Description

[Detailed description of the invention] The present invention allows even a heavy working machine to be mounted on a farm vehicle by a single worker by supporting it on a support stand without having to topple it, and by simply moving the vehicle forward or backward. The present invention relates to a work implement attachment/detachment device for an agricultural vehicle that allows for easy removal work.

Conventionally, a mounting frame is provided at the front of an agricultural vehicle, and the mounting frame is tilted in such a manner that the front is low and the rear is high, and a support base for supporting an appropriate working machine, such as a front loader, is removably mounted on the mounting frame. It is well known that front loaders can be used to accomplish agricultural tasks.

By the way, in the past, when carrying out agricultural work by mounting a heavy working machine as mentioned above on a mounting frame, or depending on the type of agricultural work, it was removed from the mounting frame in order to replace it with another agricultural machine. In some cases, many workers would have to lift the entire working machine and attach it to and remove it from the mounting frame.

Therefore, there is an inconvenience in that this kind of agricultural work cannot be accomplished without many working tools, and there is a drawback that this kind of agricultural work cannot be carried out by farmers who are workers, and there is a strong desire to improve this. It is something.

In view of the foregoing, the present invention has been devised to ensure that heavy work equipment is supported securely without falling over by using a separately prepared support stand even when a worker is working, and at the same time, the proximal end of the supported work equipment is The side can be easily lifted up and separated from the mounting frame by rotating the vibration adjustment screw, and it can be quickly removed from the agricultural vehicle by simply moving the vehicle backwards, and the work equipment can be easily attached. During work, the work equipment supported on the support frame is adjusted in advance to a height that allows it to be placed at the specified position on the mounting frame, and then it can be easily mounted on the mounting frame by simply moving the agricultural vehicle forward. The present invention is intended to provide a work equipment attaching/detaching device for an agricultural vehicle that can be easily achieved, and the configuration of the device according to the present invention will be described below with reference to a preferred embodiment shown in the accompanying drawings.

In the drawings, reference numeral 1 denotes an agricultural vehicle, and the agricultural vehicle 1 includes a chassis 2 on which a large number of wheels 3 to be driven and rotated are mounted on respective shafts, and a chassis 2 provided at a position in front of the chassis 2.

Note that the mounting base 17 is provided so as to have the same slope as the mounting frame 8 in order to be accurately placed on the mounting frame 8.

A horizontal bearing cylinder 19 is attached to the lower part of the support base 15 along the traveling direction of the agricultural vehicle 1.

20 is a support stand for the work machine 11 prepared separately,
As clearly shown in FIGS. 3 and 4, the supporting frame 20 includes a base 20a which has a triangular shape when viewed from above, and the base 20.
When viewed from the side, the vertical support rod 20b is combined with the vertical support rod 20b that stands from the center of one side of a to form an approximately 7-shaped shape,
At a position above the vertical support rod 20b, a vertical proximal end 21a of a bending support arm 21, which is equipped with a shaft 22 that can be removably inserted into the horizontal bearing cylinder 19, is attached to the vertical support rod 20b.
They are pivotally supported by a pivot pin 23 so as to be able to freely vibrate in the state in which they are joined together.

A vibration adjusting screw rod 24 is screwed onto the bending support arm 21 at a position near the bend, and the tip side thereof is connected to the vertical support rod 2.
0b.

Note that when the shaft body 22 is fitted into the horizontal bearing sleeve 19, the two are fastened together using a fastener (not shown) to ensure the fitted state.

Next, the operation of the present invention will be explained.

Now, the mounting table 17 provided on the support base 15 of the work equipment 11, for example, a front loader, is mounted on the mounting frame 8 provided on the front of the agricultural vehicle 1. If you want to make a distant relative, first move the support frame 20 to the vicinity of the support base 15 of the front loader 11, then raise the front loader 11 which was in the lying position, and then move it to the tip side of the bending support arm 21. The mounted shaft body 22 is inserted into the horizontal bearing cylinder 19 and firmly connected with an appropriate tensioning tool.

Note that when fitting the shaft body 22 into the horizontal bearing sleeve 19, the horizontal bearing sleeve 19 and the shaft body 22 are preset at the same height, so the insertion operation is facilitated by simply moving the support base 20. I can be a distant relative of

In this way, even the heavy front loader 11 can be supported upright by the support frame 20 without being laid down.

Once the front loader 11 is supported upright in this way, if the agricultural vehicle 1 is gradually advanced toward the support stand 20 as shown in FIG. The mounting table 17, which is integrally attached to the support base 15 at an inclined angle, responds to the forward movement of the agricultural vehicle 1 by locking the locking piece 1G on the front end side.
, 10 is mounted on the mounting frame 8.

Therefore, once the mounting base 17 is completely placed on the mounting frame 8, the forward movement of the agricultural vehicle 1 is stopped, and then the mounting base 17 on the opposite side to the locking side is attached with the tensioning tool 18. Then, a heavy front loader can be easily installed in front of the agricultural vehicle 1 by one worker using the support frame 20, and agricultural work by the front loader 11 can be performed efficiently.

Note that after the front loader 11 is completely mounted on the mounting frame 8, the support frame 20 can be removed after rotating the front loader 11 to either the left or right about the support tube 16.

In addition, if the mounting table 17 cannot be installed at a predetermined position on the mounting frame 8 during the above-mentioned installation work, the vibration adjustment screw rod 24 can be screwed into the vertical support rod 20b, and the bending support arm 21 can be attached to the pivot pin 23. The vibration is adjusted to the position indicated by the chain line in FIG. 3, with the mounting table 17 as the axis, and the mounting table 17 side is slightly lifted to allow the mounting operation to be carried out more easily.

Next, when the agricultural work using the front loader 11 is finished and you want to remove the front loader 11 from the agricultural vehicle 1, first rotate the front loader 11 to the left or right about the support cylinder 16 as described above, and attach it to the mounting frame. After fitting the shaft body 22 provided on the support frame 20 into the horizontal bearing cylinder 19 attached to the lower part of the support base 15 placed on the stand 8 while operating the vibration adjustment screw 24, the tension is tightened.
