Description

[Detailed Description of the Invention] The present invention provides a bullet culvert machine and a self-propelled vehicle body such as a tractor.
A ground work method in which a work machine for ground work that requires large horsepower to pull for subsoil crushing, etc. is mounted so that it vibrates using a vibrating device, and a vibratory ground work machine used to carry out the method. Regarding improvements.

A sub-soil crusher is installed on a self-propelled vehicle body such as a tractor with a chisel attached to the lower end of a vertically long blade-like shank, and a bullet (molle) is towed and connected to the rear of the lower end of the sub-soil crusher. A work machine that performs ground work that requires large traction horsepower, such as a bullet culvert machine, is mounted so that it vibrates with a vibration device, and the work machine is vibrated while being towed by the vehicle body. Means for making work more efficient are known in the art.

However, in the conventional means, the vibration device uses a cam or a crank, and the direction of motion of the vibration given to one work machine is the front-back direction along the towing direction of the work machine. As a result, when the work equipment moves backward, it pulls the towed vehicle body backward, increasing the traction resistance, and the work can only be done with a high-horsepower tractor.

In addition, if you perform ground work while towing the machine while it is still vibrating, the left and right balance will be poor and the direction of movement of the machine will be biased to one side. When multiple working machines are arranged side by side on the left and right, there is a problem that the working machines located on one side of the left and right may float up or the progress of one machine may meander.

The present invention has been made in order to solve these problems, and it reduces the traction resistance of the work machine during ground work performed by vibrating the work machine, so that the vibration-type ground work can be carried out without requiring large horsepower. The first purpose is to provide a new means to perform work efficiently, and also to improve the left and right balance so that even if multiple work machines are installed side by side on the left and right, the - side A second object of the present invention is to provide a new means that does not cause lifting of the working machine or bias the progress of the machine.

The present invention was completed based on the knowledge obtained through various studies and experiments for the above-mentioned purpose. That is, in order to solve the above-mentioned problem, as shown in FIG. When supporting it so that it vibrates, the vibration excitation device C
By configuring the machine so that the direction of vibration generated by it is in the vertical direction, the machine for ground work mainly vibrates in the vertical direction, and when the machine vibrates, the towing vehicle body This eliminates the inconvenience of pulling the plow backwards, reduces traction resistance, and makes it easier to perform ground work by vibrating the work equipment with relatively low horsepower. Ta. However, this result does not mean that the traction resistance can be reduced in the same way if the vibration excitation device C that vibrates the work machine is made to vibrate in the vertical direction. There were differences in the reduction of traction resistance depending on the mounting position of the machine.

Therefore, we conducted further experiments and found that when a work machine for ground work is vibrated using a vibrating device C whose vibration direction is vertical, the traction resistance of the work machine is as follows:
It changes depending on the mutual positional relationship between the evoking force line W of the vibration generating device C and the approximate center P of the traction resistance of the work implement, and the approximate center P of the traction resistance of the work implement is Vibrating device C
It can be seen that this traction resistance is reduced by supporting the device so that it is located near the evoking force line W of the excitation device C.The center of the drag is located near the evoking force line W of the excitation device C. This is because the unnecessary stress applied to the machine frame a that supports the work machine will be reduced, and the work 411b will be vibrated with no loss in the vibration force of the vibration excitation device C. It is thought that.

In addition, when supporting a vibrating work machine on a machine frame, a vertical imaginary line passing through the approximate center of the traction resistance of the work machine is the same as the evoking vibration force line of the vibration excitation device when viewed from the rear. By arranging them so that they overlap and supporting them on the machine frame, the balance between left and right is improved and the straightness of the machine is improved. When viewed from the rear, the vertical imaginary lines passing through approximately the center of their traction resistance are arranged symmetrically to the left and right about the axis of symmetry, and the axis of symmetry is aligned with the vibration exciter. When the machine was supported on the machine frame so that it overlapped with the eccentric force line when viewed from the rear, the left and right balance was well maintained, and problems such as lifting of the work machine on the negative side were eliminated. -It was.

From this, in the present invention, as a means for achieving the above-mentioned first object, a towed type is provided on a machine frame supporting a vibration excitation device whose movement direction of vibration is the vertical direction. A working machine for ground work is supported in a key such that the approximate center of its traction resistance is located in the vicinity of the fti-induced vibration direction of the vibration exciter when viewed from the side, and the machine is caused to act on the ground. We have proposed a vibration-type ground work method characterized by carrying out ground work by towing it while vibrating it from a vibration device, and in order to carry out this method, we have developed a device such as a tractor as a second device to carry out this method. A vibration excitation device whose vibration direction is vertical is installed on a machine frame provided on a self-propelled vehicle body. Abbreviation for traction resistance! M1
Means for achieving the second object by providing a vibratory ground working machine which is arranged and supported so that its parts are located substantially on the line of force of the vibration excitation device in side view, and As a machine frame installed on the body of a self-propelled vehicle such as a tractor,
By assembling a vibration excitation device in which the direction of vibration is vertical, the type 9 work machine for ground work can be transformed into 1. A vibratory ground work center supported so that a vertical imaginary line passing through the approximate center of the traction resistance substantially overlaps the imaginary vibration force line of the vibration excitation device in rear view. and for machine frames installed on self-propelled vehicles such as tractors.

In addition to assembling a vibration excitation device whose vibration movement direction is the vertical direction, the towed type ground work work equipment that is vibrated by the vibration excitation device is arranged in multiple rows in the left and right direction, symmetrical about the axis of symmetry. parallel to.

In addition, the present invention proposes a vibratory ground working machine which is arranged and supported so that its axis of symmetry substantially overlaps the bale-induced vibration force line of the vibration excitation device when viewed from the rear.

Next, an example of implementation will be described in detail with reference to the drawings.

FIG. 2 is a side view of the vibrating ground working machine A used for carrying out the method of the present invention, which is attached to the rear side of the vehicle body of a tractor T.
In the figure, T indicates a tractor, and A indicates a vibrating ground-based working machine mounted on the rear of the vehicle body of the tractor T.

A top link 10, left and right lower links 11@11 (one is omitted in the drawing), a lift arm 12, and a PTO shaft 13 are installed on the rear side of the vehicle body.

A vibrating ground work machine A has a machine frame a and a work machine supported on the machine frame a.
The machine frame a, which is made up of the vibration mount Mc assembled to the An assembling machine frame 20 is mounted so that it can be raised and lowered, and a connecting fulcrum 21 is mounted on the rear side of the assembly machine frame 20.

4 and more. And a frame 2 formed into the shape of a machine casing.
The vibration device IC for vibrating the work machine is installed inside the 4.

A tool bar 25, which serves as a hitch for attaching the working machine, is installed at the bottom of the rear side with a mounting bracket 26.

The work machine has a shank 30 that is shaped like a long blade plate on the top and bottom.
3, the chisel 31 and wing 32 are installed in one stage or in multiple stages as shown in Fig. 3, and the shank 30 of the
The upper end portion of the tool bar 25 is provided on the frame 24 described above.
It is integrally assembled to the frame body 24 by being fastened to a clamp 27 which is slidably fitted to the frame body 24.

As shown in FIG. 4, the clamp 27 has a sheath cylinder 270 formed into a rectangle in side view so as to hold together the tool bar 25 and the upper end of the shank 30 of the working machine.
Fitting slots 271, 271 in the front and back direction through which the upper end of the shank 30 loosely passes are provided on the rear sides of both the upper and lower walls of the shank. Fitting protrusions 2 formed at both upper and lower ends of the plates 272, 272
72a and 272a, respectively, and a threaded rod 273 that pushes forward the rear patch plate 272 of the two patch plates 272 and 272 is screwed onto the rear wall of the sheath cylinder 270. The sheath tube 270 is placed on the tool bar 25.
The upper end of the shank 30 is positioned between the two backing plates 272 when inserted into the sheath *
Fitting groove 271-2 opened in the earthen wall and lower wall of 270
71 and then tightening the screw rod 273 in this state, the fixation to the tool bar 25 and the tightening of the shank 30 are performed at the same time.

Then, the clamp 27 is pulled out from the tool bar 25, rotated 180 degrees so that the rear end side protrudes forward, and in that state is inserted again into the tool bar 25 to secure the upper end of the shank 30 of one work machine. By doing so, the work implement is attached to the front side of the tool bar 25. That is, in this way, one assembly of the working machine is attached to the frame 2.
It is designed to serve as an adjusting means for displacing the head back and forth with respect to 4. In addition, a pair of backing plates 272 are provided before and after the clamp 27.
・272 is connected by a flexible joint 274.

As shown in FIG. 5, the vibration excitation device C assembled in the frame body 24 is placed between the front wall 240 and the rear wall 241 of the frame body 24, which is formed in the shape of a machine casing. Two rotary shafts 40 @ 41, which are oriented in the same direction, are arranged side by side on the left and right and supported across a rack, and unbalancers 42 are respectively attached to these rotary shafts 40 @ 41, and gears 43 and 44 mesh with each other.
The gears 43 and 44 are engaged with each other with the unbalancers 42 . . . positioned below as shown in FIG. Before! ! ! The input shaft 4 is projected forward from 240.
5 is an unbalancer type vibration excitation device, and when its input shaft 45 is driven, a pair of parallel rotating shafts 40 and 41 rotate in synchrony and oppositely, thereby causing the unbalancer 42 42 rotates synchronously in the direction of the arrow in FIGS. 8 and 9, thereby eliminating the movement in the left and right directions and generating vibrations in which one direction of movement is the up and down direction. The input shaft 45 is connected to the PTO shaft 13 of the tractor T via a universal joint shaft 46, and is driven by the prime mover on the tractor T side.

The vibration excitation device C that generates vibrations in which the direction of motion is vertical is composed of two unbalancers 42, 42, which are a set of two unbalancers. 42, 42 may be provided in multiple rows in the left and right direction. In this way, when the unbalancers 42, 42 of the set that generates vibrational force in the vertical direction are arranged in parallel in the left and right direction, one working machine is arranged in parallel in the left and right on the tool bar 25 provided on the frame 24 mentioned above. This makes it more suitable for multiple installations.

In addition, the vibration excitation device C configured by combining two unbalancers 42, 42 into a -set only needs to be such that the direction of movement of the generated vibration is in the vertical direction, The rotating shafts 40 and 41 of 42 may be combined vertically in parallel with the direction of the axis line along the front-rear direction, or the direction of the axis line of the rotation axis 40 and 41 may be in the left-right direction. They may be configured by combining them so that they are arranged in front and back or vertically in a posture along the same lines.

Therefore, the work machine C supported on the frame 24 so as to move mainly in the vertical direction by this vibration excitation device C (the frame 24 is elastically expanded and contracted like a shock absorber with the lower arm 22 rotating vertically). By being supported by the upper arm 23 and moving in a direction that is a combination of the up-down direction and the front-back direction as shown in FIG. ), when the tool bar 25, which is a pitch provided on the frame body 24, is supported via the clamp 27, the portion P, which is approximately the center of the traction resistance of the work implement, is as shown in FIG. 2 in a side view.
It is arranged so as to be located below the vibration excitation device C provided on the machine frame a, and is assembled to the frame body 24, so that the approximate center P of the traction resistance of the work ab is It is arranged to ride on the evoking force line W of the oscillating device C.

When viewed from the side, the line of force W appears to be a zone in the vertical direction with the width of the unbalancer 42 built into the frame 24 and pivotally supported, but here it is shown as the center line of that zone, and Approximately the center P of the traction resistance is placed on the quasi-reflective vibration normal line W, which is the center line, when viewed from the side. However, as the frame body 24 is regulated by the movement of the lower arm 22 and the upper arm 23 as described above and moves in the front-back direction, the evocative force line W does not always remain at a constant position. Since it fluctuates somewhat around 1,
Approximately, it is sufficient that the approximate center P of the traction resistance of the working machine rests on this simulated vibration force MAW when viewed from the side.

Further, the relationship between this evoking force line W and the approximate center P of the traction resistance of the working machine in rear view is as follows in the work II of supporting the work machine on the frame 24! When 1b is single, as shown in Fig. 11, the vertical bale imaginary line Y passing through the approximate center P of the traction resistance of the working machine is placed on the bale imaginary vibration force line W.

Next, FIG. 13 shows another embodiment.

In this example, one working machine has a chisel 31 installed on the shank 30.
This is an example of a bullet underdrain machine with a bullet (underdrain forming machine) 33 towed behind it, and the rest of the basic configuration is the same as the above-mentioned embodiment except for the change in work Itb. The same constituent members are given the same reference numerals and detailed explanations are omitted.Next, Fig. 1.4 shows a tool bar 25 which is a pitch part on which a working machine is assembled and supported on a frame 24.
3 shows another embodiment of the part. In this example, the tool bar 25 constituting the pitch portion is supported by a mounting bracket 26 that is attached to the belt, and the mounting bracket 26 is attached to the frame body 24 or to the frame body 24 by an assembly port 250. By assembling it to the mounting plate 251, it can be attached to the frame body 24. And, on the mounting plate 251, 1

The mounting angle of the tool bar 25 changes, and the tool bar 2
The posture of the work equipment attached to the frame 24 changes, and this causes the adjustment of the approximate center P of the traction resistance of the work mb back and forth with respect to the frame 24, that is, the adjustment of the vibration excitation device C assembled to the frame 24. This is so that adjustments can be made back and forth with respect to the line of vibrational force W.

As explained above, in the means of the present invention, while vibrating a towed type work machine for ground work with high traction resistance such as Shinshi crushing machine, bullet culvert machine, deep cultivating machine, etc. using vibration exciter C, By towing, it can crush subsoil, form bullet culverts,
When performing ground work such as deep plowing, the vibration excitation device C is configured so that the movement direction of the generated vibration is in the vertical direction, and the vibration excitation device C is configured so that the approximately center point P of the traction resistance of the work machine b is the vibration excitation device C when viewed from the side. Since the device 2tc is mounted on the machine frame so as to be located approximately on the bale-induced vibration force line W, the vibration force in the vertical direction generated by the vibration device C is reduced by a loss. This effectively vibrates the work equipment even when the machine is not in use, improving the vibration effect and reducing traction resistance.Furthermore, the work equipment mainly vibrates in the vertical direction, making it difficult to tow. The inconvenience of pulling the vehicle backwards is eliminated, and the work can be done even with a small horsepower tractor.

In addition, when supporting a work machine for ground work that is towed while being vibrated by the vibration mount MC on the machine frame, the vertical dimension MY that passes through the approximate center P of the traction resistance of the work Ilb is determined when viewed from the rear. Since it is designed to approximately overlap the evoking force line W of the vibration excitation device C, the vertical vibration force generated by the vibration excitation device C can be applied to the work machine without losing the horizontal balance of the work machine. This will allow you to perform ground work in a well-balanced manner.

Also, when multiple working machines are arranged in parallel on the left and right, vertical bales pass through the approximate center P of the traction resistance of the working machines!
