Description

DETAILED DESCRIPTION OF THE INVENTION This invention provides a conveyance passage into which grass is charged from the inlet side and which communicates with the loading chamber of the coder vehicle at the outlet side, and a conveyance passageway that passes through the upper wall and protrudes toward the bottom wall within the conveyance passageway. The present invention relates to a lawn mowing loading vehicle or loader vehicle having a number of conveyor plates which together with a cutter extend into the conveyor path through the bottom wall.

In the case of loading vehicles or loader vehicles with a cutter in the transport path, the blade of the cuckoo is continuously loaded with the material to be cut during operation and wears out over time.

The blade wears out at a speed determined by the type of grass, cutting speed, cutting width, presence of foreign matter in the harvested grass, etc. For this reason, the cutter blade has conventionally been taken out separately, sharpened and then put back in its original position, as described, for example, in DE 1916046.
k&jru.

However, after the cutter to be taken out is removed by a vise or other tightening device, it is manually removed by a grinding device.
Since the grinding is done in step b, it is a time-consuming and troublesome work that reduces the weight of the eggs. Moreover, the cutter blades are typically sharpened non-electrolytically, inaccurately and unevenly, which causes them to wear out more quickly during operation.

SUMMARY OF THE INVENTION The object of the invention is to provide a rogue mowing vehicle of the type mentioned at the beginning of this section, which makes it possible to sharpen the cutter accurately and easily without much effort.

According to the present invention, a sharpening device for sharpening the cutter is arranged in the area of the conveyor plate together with a sharpening unit movable at right angles to the conveyance direction and swingable or movable in the plane of the cutter. It is resolved by

This allows you to sharpen the cutter easily and accurately.

By rotating the sharpening unit, the operator can accurately sharpen the cutter without requiring much force.

According to a preferred embodiment of the invention, by loosening the hinge, the bottom wall can be swung together with the cutter into a lower position, which is also the sharpening position of the sharpening device.

This makes it easier to access the sharpening device, and also makes it easier to install and rotate the sharpening device.

According to another feature of the invention, the sharpening device is removably supported on the side of the conveying path (jl wall) via the horizontal pipe, and the sharpening unit is arranged on the horizontal pipe so as to be swingable and transversely movable. This lateral movement can be suppressed through suitable fixing devices.

When installing the sharpening device, it may be advantageous for off-duty use if the cutter has a concave shape and the center of curvature of the concave cutter blade coincides with the central axis of the horizontal tube when the bottom wall is swung outward. know.

While sharpening the cutter, in order to make one swing of the sharpening unit sufficient, the grinding disc is oriented diagonally in correspondence with the cutter blade, and the grinding disc is rocked on a movable bearing on the horizontal tube. It is proposed to drive by means of a drive motor connected via a drive shaft.

It is also desirable to provide the sharpening unit with a push rod mounted parallel to the handle or side tube.

By providing the push rod, the operator can sharpen the cutter from the negative side, and there is no need to dig into the bottom of the rogue wheel.

Furthermore, since almost all factories are equipped with a disc sander (disk type grinding device), it is possible to use a disc sander that can be fixed in the swing path as a sharpening unit.

Using a hydraulic motor or gearing with a flexible shaft allows the cutter to be resharpened in the field where only a tractor is available as an energy source.

This eliminates the need for extra length. If several rows of cutters are arranged in a staggered manner, it is advantageous to form further receiving openings in the side walls of the conveying channel for interchanging the inserts of the sharpening devices. This allows the same grinding conditions used for the first cutter row to exist for the next cutter row. According to a further feature of the invention, the cutters have a safety device against overload and can be swung outwards either separately or together.

In order to swing the cutter into the sharpening position, it is proposed to arrange a pushing device behind the bottom wall and limit the pushing path downwards. This reduces the rotational force required when pushing by hand.

The present invention will now be described in further detail with reference to preferred embodiments shown in the drawings. FIG. 1 shows the front part of a rogue vehicle 1 with a reaping device.

The reaping device consists of a pink amplifier and a rotating 1M feeder 4 placed behind it, and the rotary feeder 4 is followed by a plurality of feeder plates 5. The conveyor plate 5 cooperates in the conveyor path 6 with canters 7, 8 arranged in series.

The cutter 7.8 is protected by an overload safety device 9, as shown in FIG. The conveyance path 6 is formed by an upper wall 1o provided with a through hole, a closed bottom wall 11, and tRU section walls I2 and I3.

The cargo to be loaded is stored via the drag conveyor 15 to a unloading device (not shown). The loader vehicle 1 is towed by an axle 16.

As can be seen from FIG. 1.2, the bottom wall 11 is fixed in position and can swing downward around the saw pivot axis I7.

The swinging path is limited by the pushing device 18. Bottom wall】1
When the cutter 7.8 is rotated, the cutter 7.8 simultaneously follows the rotation. The cutter 7.8 can also be rotated separately from the conveying channel 6 about the pivot axis 19.2o without changing the position of the bottom wall 11. For this purpose, the cutter 7 is rotatably supported on a cutter support member 21 and a fixing device 2
It can be fixed via 2.

As can be seen from FIG. 2, the downward swinging position of the bottom wall 11 is also the sharpening position of the cutter 7.8.

A sharpening device 23 for sharpening the cutter 7.8 is supported by a cross tube 24 in the side wall I2.13+t1.

The horizontal pipe 24 is prevented from moving in its longitudinal direction by the fastening device 30.
Fixed by A longitudinally movable pivot bearing 25 is arranged on the cross tube 24, and the pivot bearing 25 carries a prime mover 27 by means of a swing shaft 26. A prime mover 27 drives a grinding disk 28 . The prime mover 27 is equipped with a manual lever or handle 29 for swinging the sharpening device 23. The driving force +a27 may be an electric motor or a hydraulic motor. 27a is a connecting conductor. As can be seen from FIG. 3, the swing shaft 26, together with the prime mover 27 and the grinding disk 28, is mounted obliquely to the cutter 7.8, which means that the blade of the cutter 7.8 is It is necessary to sharpen to the desired angle. prime mover 2
7. For this purpose, the swing shaft 26 can be carved into various swing positions and fixed at these positions.

It is also possible to use another fastening device (not shown) to fix the side portion of the swing shaft 26.

According to the embodiment of the elbow shown in FIG. 4, an independently wearable sharpening device, for example a disc sander 31, is fixed to several diagonally arranged pivot shafts 26.

For the purpose of lateral movement, the rocking shaft 26 has a push rod 32 by means of which a lateral displacement from the rogue vehicle 1 can be effected.

As shown in Figure 1.2, two sets of horizontal pipes 24 are removed.
The through holes 33a, 33b, and 33C233d are formed in pairs at different heights. The hole 33a is necessary for sharpening the lower cutter 7.

The sharpening operation is performed as follows. After stopping the reaping device 2, the bottom wall 1 is moved downwardly around the pivot axis 17 to a position where further rotation is limited by the pushing device 18.
1 is rotated by a pushing device 18.

The pushing device 18 is formed by a push rod, which acts on a rear bearing point of the bottom wall 11. The entire pushing device 18 is not shown in order to simplify the drawing. The pushing motion can be carried out manually via a Hercrankliner or via hydraulic or electric auxiliary devices.

When sharpening the upper cutter row including the cuckoo 8 while the bottom wall 11 is swung downward, the lower cuckoo row is swung downward by the cutter support member 21 (solid line position v in FIG. 2). ). Next, the sharpening device 23 is inserted obliquely into the through hole 33a together with the horizontal pipe 24, and the through hole 33a is oriented straight.
