Description

[Detailed description of the invention] The present invention allows a heavy container with a rabbit to be lifted onto a pedestal that is placed on the rear body of an agricultural vehicle so that it can be moved up and down precisely by the backward movement of the agricultural vehicle. This invention relates to a lifting device for containers with legs on agricultural vehicles that can easily achieve the following.

Conventionally, as part of agricultural work using agricultural vehicles, a heavy container with legs is installed in advance at a predetermined height on the ground via multiple fixed support legs, and a guide rail provided at the bottom of the container with legs is used. The agricultural vehicle enters the bottom of the container with legs while moving backwards along the road.The agricultural vehicle then lifts it onto a platform that can be raised and lowered, and after transporting it to a desired location, lowers the container with legs to the ground again, leaving only the agricultural vehicle alone. A lot of work is being carried out to transport containers with legs, in which the containers are moved forward and placed in a desired location to carry out agricultural work.

By the way, in the past, all of the multiple support legs attached to the bottom of the container were fixed, so when lifting a container with legs, it was necessary to accurately move the agricultural vehicle backwards along the guide rail. However, if the agricultural vehicle does not enter the bottom of the container with legs, the pedestal and guide rail will collide and the agricultural vehicle will not be able to enter, or the collision load when reversing will be applied to the fixed support legs, causing them to bend or break. This caused unexpected accidents, and as a result, there was an inconvenience that required considerable skill to work on mounting agricultural vehicles.

In view of the above, the present invention is equipped with a pair of pedestal entry guide upright walls in the longitudinal direction of the bottom of a container with legs, which is equipped with two non-rotating legs at the front and one rotating leg at the center of the rear. At the same time, on the outside of the stand entry guide upright wall, a pair of stands are mounted on the rear body of the agricultural vehicle so as to be movable up and down, and furthermore, a pair of stands having a plurality of rolling rollers arranged on the upper surface can enter while in contact with each other. Alternatively, a removable guide rail can be provided to allow the container with legs to be pivoted around the single pivoting support leg provided at the center of the rear, even if the backward movement of the agricultural vehicle is inaccurate when the container with legs is mounted on top of the container. A container with legs can be rotated to suit the direction of approach of an agricultural vehicle, and the container with legs can be smoothly mounted on the stand without colliding with the platform, and the transportation and installation work of the container with legs can be accomplished without requiring any operating skills. The purpose of the present invention is to provide a device for hoisting a container with legs on an agricultural vehicle, which prevents accidental breakage or bending of the supporting legs in order to eliminate collisions during hoisting operations, and the following: DESCRIPTION OF THE PREFERRED EMBODIMENTS A preferred embodiment of the configuration of the device according to the present invention will be described below, as shown in the accompanying drawings.

In FIG. 1, reference numeral 1 denotes a multi-wheeled agricultural vehicle. A driver's cab 4 and a motor room 5 are provided in the vehicle body 2, and a frame 7 is installed at the rear of the vehicle body 2 via a hydraulic lifting device 6.

The hydraulic lifting device 6 includes parallel links 8a and 8b having one end pivotally connected to the vehicle body 2, the other end pivotally connected to the frame 7, and a piston rod 1 of a hydraulic cylinder 9 having one end pivotally connected to the vehicle body 2.
The other end of 0 is pivotally connected to the pedestal 7.

The above-mentioned pedestal 7 is constructed by integrally connecting two left and right parts at intervals, and a plurality of rolling rollers 11 are provided on the upper surface of the pedestal 7 at appropriate intervals. There is.

Reference numeral 12 is a container with legs that can store harvested grass, etc., dry harvested paddy, and perform other appropriate agricultural work at any time. has two non-rotating support legs 13, 13,
Further, one rotary support leg 14 is vertically attached to the lower center surface of the rear portion.

The rotation support leg 14 consisting of the above-mentioned one rotation support leg 1
The legged container 12 may be any type as long as it can freely rotate in the left and right direction about the fixed supporting leg 14a. It is constructed by connecting and installing the two.

In the bottom longitudinal direction of the legged container 12 formed as described above, the front edges 16a, 16a and the rear edges 16b, 16b are folded inwardly, as shown in FIGS. 2 and 3. A pair of curved pedestal entry guide standing walls 16,1
6 are installed at intervals between the frames 7, and the two frames 7 are installed on the outside of the pair of frame entry guide upright walls 16.16 while maintaining the abutting state. A guide rail 17.17 that can be entered or removed along the guide rail 17.16 is installed, and the starting end side 17a, 17a and the rear end side 1 of the guide rail 17.17 are installed.
Both 7b and 17b are obliquely cut.

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

Now, there are two non-rotating supporting legs 13.13 and one rotating supporting leg 14.
A mount 7 is provided at the rear of the agricultural vehicle 1 so that the container 12 with legs installed on the ground can be raised and lowered freely.
If you want to transport the legged container 12 to an arbitrary location by lifting it up, first, as shown in FIG. After raising the agricultural vehicle 1 horizontally to a height slightly above the ground, the agricultural vehicle 1 is moved into a container with legs so that the pedestal 7 comes into contact with the lower surface of the guide rail 17.17 while following the pair of pedestal entry guide upright walls 16.16. Move backwards towards 12.

Then, as the agricultural vehicle 1 moves backward, the gantry I is guided by the pair of gantry entry guide upright walls 16 and 16 and enters in contact with the pair of guide rails 17 and 17, and reaches the front of the legged container 12. Lift up the section and place it on the pedestal 7.

When the front part of the legged container 12 is mounted on the pedestal 7 in this way, if the agricultural vehicle 1 is further moved backwards under the same condition, the pedestal I and the guide rails 17, 17 will be connected to the rolling rollers 1.
1..., the pedestal 7 smoothly enters deep into the legged container 12, and the entire legged container 12 is placed on the pedestal 7.

By the way, during the above-mentioned overhead work, due to a maneuvering error or the like, the direction of approach of the gantry 1 may be incorrect due to the pair of gantry entry guide upright walls 16.
, 160 When the container is entered from an oblique direction that does not match the installation direction, the container 12 with legs rotates around the rotating support leg 14 at the center of the rear part that is in contact with the ground, and guides the gantry into the gantry so that it follows the direction in which the gantry 7 enters. Since the direction of the upright wall 16.16 is automatically corrected, simply reversing the agricultural vehicle 1 will cause the mount 7 to smoothly move along the guide rail 1 along the mount guide upright wall 16.16.
7.17 It can be entered while rolling on the top and the lifting work can be easily accomplished.

Therefore, even those who are not skilled in operating the container with legs can
Is it a scam that can easily accomplish the work on the 2.
Accidents in which the supporting legs are bent or broken due to the collision load caused by the approach operation from an unreasonable angle can be prevented.

When the cape-equipped container 12 is completely mounted on the pedestal 7, the legged container 12 is further raised by the lifting/lowering operation of the pedestal 7, and after the supporting legs are not in contact with the ground, it is transported to a desired location by the agricultural vehicle 1.

When the desired installation position is reached, the container 12 with legs may be placed on the ground by performing the exact opposite operation as described above.

Note that the tip edges 16 of the pair of gantry entry guide upright walls 16, 16
a, 16a and rear end edges 16b, 16b, respectively, are bent inward, and a pair of guide rails 17, 17 are formed.
Since both the starting end sides 17a, 17a and the rear end sides 17b, 17b are cut obliquely, the entry and removal actions of the frame 7 can be achieved smoothly.

In short, the present invention has two non-rotating support legs 13.13 at the front.
In addition, a pair of gantry entry guide upright walls 16.16 are attached to the bottom longitudinal direction of the legged container 12, each of which has one rotary support leg 14 at the rear center, and the gantry entrance guide upright walls 16.16 A guide rail 17 is placed on the outside of the rear body 2 of the agricultural vehicle 1 so as to be movable up and down, and a pedestal 7 having a plurality of transfer rollers on its upper surface can enter or leave while in contact with the guide rail 17. 17, the heavy legged container 12, which has been previously installed on the ground via three supporting legs, can be lifted onto the pedestal 7 by simply reversing the agricultural vehicle 1, and easily transported to a desired location. However, if there is a case where the approach direction of the gantry 7 is different from the installation direction of the gantry entry guide upright walls 16, 16 due to a maneuvering error or the like during the work on the upper structure, The container 12 with legs is freely rotated around one rotation support leg 14, and the direction of the pedestal entry guide upright wall 16.16 is automatically matched with the direction of entry of the pedestal 7. As a result, bending and breakage of the supporting legs caused by forced entry from an unreasonable angle are completely eliminated, and even an individual can smoothly carry the container 12 with legs. Make the most of your efforts.
