Description

Detailed Description of the Invention The present invention relates to a traveling device in an axle working machine.

In other words, in an axle work machine configured by attaching tillage tines or the like to both axles extending out on either side of the transmission case and attaching circular plates with a smaller diameter than the tillage tines or the like to the free ends of both axles, when the axle work machine is driven on the road surface or loaded onto and unloaded from a transport vehicle, it can be moved forward and backward stably, reliably, and smoothly without damaging the tillage tines or the like of the axles or damaging the road surface, and its simple shape makes it easy to attach and detach, making it suitable for practical use.

Next, the embodiment shown in the drawings will be described.

FIG. 1 shows a side view of the entire axle-axle working machine. This machine, which is usually called a management working machine, has a front frame 8 connected to the front part of a transmission case 1 which has a handle 7 connected to its upper side. , from the engine E mounted above the front frame 8 to the transmission case 1
The driving shafts 10, 10 protruding from both sides of the lower part of the Mitsushiyo case 1 are equipped with both axles 2, 2 having a large number of tilling claws 3 arranged around them. Bolts 11 and 1 are fitted and inserted into both axles 2 and 2, respectively.
1, but both discs 4, 4 are fitted to both ends of both axles 2, 2 to allow the machine to move straight and stabilize the plowing depth, and are fixed with bolts 11, 11. Numerals 4 and 4 are formed approximately in the shape of a bowl and have a slightly smaller diameter than the tilling claws 3, similar to the conventional structure.

Note that a drum rotor or other working equipment can be attached to the drive shafts 10, 10,
It can be equipped with wheels.

Keyhole-shaped holes 12 each having a large diameter hole 12a at one end are formed at three equally spaced positions on the side surfaces near the outer periphery of both discs 4, 4, facing in the same direction.

A shows the entire ground wheel plate, which is formed so that an annular side plate part 14 with a circular hole 13 punched in the center can be joined to the outer surface of the disk 4, and the side plate part 1
The outer circumferential surface connected to the outer periphery of the tilling claws 4 is integrally pressed and formed into a narrow cylindrical contact surface through the arc-shaped curved surface portion R, and the outer circumferential surface 5 has a diameter larger than that of the tilling claws 3. Form it into a foil shape so that the side plate part 1
One locking tool 6 made of bolt is placed at the 3rd equally spaced position of 4.
One end of two locking tools 6b, 6b made of a riveted pin having a head 15 at the tip of the locking tool 6a is secured to the locking tool 6a, and a wing nut 16 is installed on the locking tool 6a so that it can be hinged. do.

Note that only the locking tool 6a is attached to the ground wheel plate A.
Alternatively, only the locking tool 6b is installed,
It can also be configured to be detachable using other locking tools.

Further, FIG. 15 shows another embodiment, which is indicated by the same reference numerals as the previous embodiment and has substantially the same structure, except that the side plate portion 14 has the mounting portions for the fasteners 6a, 6b, and 6b left. It is constructed by punching out a large size to make it lightweight.

As shown in FIG. 16, several weld nuts 17 are fixed on the inside of both discs 4, and a ground wheel plate A is joined to both discs 4, and a butterfly bolt 18 is inserted from the outside of the ground wheel plate A. The ground wheel plate A may be attached by inserting the ground wheel plate A through the welding nuts 17 and hinged to the weld nuts 17.

Therefore, during normal work, the ground wheel plates A,
With A removed, the work is carried out in the same manner as before in the conditions shown in Figures 1 and 2, and the discs 4 and 4 at both ends are removed.
4 allows the machine to move straight and stabilizes the plowing depth.

When driving on the road or loading/unloading onto a transport vehicle, align the side plate portions 14 of both grounding wheel plates A, A with the outer surfaces of both discs 4, 4, and tighten each locking tool 6a, 6b, 6.
Align the tip of b with the large-diameter hole 12a side of each hole 12, and insert the locking tool 6a as it is, and fit the head 15 of both locking tools 6b with the large-diameter hole 12a, and from that state, insert the ground ring. Rotate plates A and A to attach each locking tool 6.
a, 6b, 6b are fitted into the other end of each hole 12 to prevent the head 15 from falling out.
When the wing nut 16 is screwed onto the tip of the locking tool 6a protruding inward from the inside and tightened, both ground wheels A, A are fixed to both discs 4, 4. You will be able to do that.

Therefore, the outer circumferential surfaces 5 of both grounding wheels A, A come into contact with the ground, and it is possible to support the tilling claws 3 so that they do not touch the ground, and when driving on the road, the tilling claws 3 do not touch the ground and are therefore not damaged. It is possible to move the aircraft forward and backward without damaging the road surface, and it does not sway when loading or unloading onto a transport vehicle.
This will allow you to maneuver smoothly.

In this way, the present invention is constructed by attaching tilling claws, etc. to both axles extending on both sides of the transmission case, and attaching disks with a smaller diameter than the tilling claws, etc. to the free ends of both axles. In the axle working machine, the outer surfaces of both discs have a grounding surface having a larger diameter than the discs and the tiller claws, etc., and the outer peripheral surface is bent to one side to form a narrow ground surface. The wheel plate is attached so as to be removably fixed via a locking device, and the ground plane covers the outer periphery of the disk, so it can be driven on a road surface or loaded onto and unloaded from a transport vehicle. In such cases, by aligning the ground wheel plate with the outer surface of the disc and easily fixing it with a locking device, it is possible to prevent the tiller claws, etc. from being damaged due to contact with the outer peripheral surface, which has a larger diameter than the tiller claws, etc. Alternatively, it is possible to move forward or backward stably, reliably, and smoothly without damaging the road surface, and it is safe because the outer periphery of the disc is covered to prevent the disc from harming other objects. In addition, a ground wheel plate can be installed to prevent the width of the axle from becoming wider, improving running performance.
The ground wheel plate has the advantage that it can be easily manufactured by press molding, can be made lightweight, has a simple shape, can be easily attached and detached, and can be suitably implemented.
