Description

[Detailed description of the invention] This invention allows for easy movement of the multi-wheeled agricultural vehicle by simply moving the multi-wheeled agricultural vehicle back and forth even when the height of the cargo box loaded with various agricultural machinery or crops does not match the height of the multi-wheeled agricultural vehicle's chassis. It is possible to carry out various agricultural tasks smoothly and improve cargo handling and transportation efficiency by loading the cargo boxes directly onto the chassis or by loading them on the ground. At the same time, the present invention attempts to provide a device for attaching and detaching a cargo box for a multi-wheeled agricultural vehicle, which is capable of firmly locking the cargo box to the chassis and preventing accidents such as accidental movement and falling of the cargo box during driving operation. The configuration of the device of the present invention will be described below with reference to a preferred embodiment shown in the accompanying drawings.

Reference numeral 1 denotes a multi-wheeled agricultural vehicle which is composed of a driver's seat 2, a chassis 3 with a large number of wheels 4 on both left and right sides, and a cargo box 5, and the chassis 3 and the cargo box 5 are constructed separately. ing. A guide rail 6 having an entry guide 7 tilted downward and provided on the starting end side is directly fixed to the approximately central longitudinal position on the chassis 3, and a pair of fittings are attached to the left and right rear end positions of the chassis 3. Locking metal fittings 8, 8 are attached. On the front back side of the loading box 5, which is separated from the chassis 3 and can be loaded with appropriate agricultural machinery or agricultural products, is a roller 9 that rolls along a guide rail 6 and whose extension can be freely adjusted and can be raised or lowered. A jack 10 whose proximal end side is pivoted so that
The packing box 5 can be easily placed on the chassis 3 by pushing it onto the chassis 3. At the left and right positions on the rear back side of the cargo box 5, there are a pair of fitting metal fittings that are fitted and engaged with the extension adjustment and undulating jacks 11, 11 whose base ends are pivotally connected, and the fitting locking fittings 8, 8, respectively. Tools 12, 12 are attached.

An engaging protrusion 13 is protruded from the front of the cargo box 5, and the engaging protrusion 13 is connected to a fitting installed at an appropriate location on the multi-wheeled agricultural vehicle 1 when the cargo box 5 is placed on the chassis 3. It is fitted into the alloy tool 14 and locked. Reference numeral 15 denotes a bullet for towing the jack 10 so that it is always upright.

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

Now, the cargo box 5 with a suitable agricultural implement (not shown) installed therein is roughly adjusted to match the height of the chassis 3 of the multi-wheeled agricultural vehicle 1 by the raising and lowering action of the three jacks 10, 11, and 11. Stand it horizontally. Next, the multi-wheel agricultural vehicle 1 is connected to the guide rail 6, the rollers 9, the fitting locking fittings 8 and the fitting fittings 12.
The cargo is moved backward toward the cargo box 5 so that they match. Then, the roller 9 is guided by the entry guide 7 provided at the starting end and tilted downward and is quickly fitted into the guide rail 6, and the rolling action allows the roller 9 to easily move the chassis 3 to the lower part of the cargo box 5. to enter. However, during the approach operation of the chassis 3, the jack 10 pivotally attached to the front back surface of the cargo box 5 is forced to fall down against the urging force of the bomb 15 as the chassis 3 moves in. As the backward motion of the chassis 3 gradually moves toward the terminal position, the front side of the cargo box 5 is completely supported by the rollers 9 rolling in the guide rail 6 while being mounted on the chassis 3. At the end of the backward motion, the cargo box 5 is loaded onto the chassis 3, and the engagement fittings 12, 12
are fitted into the fitting locking fittings 8, 8, and the engaging protrusion 13 is fitted into the fitting fitting 14, respectively, to securely lock and place the cargo box 5 without moving it inadvertently in the left, right, front and rear directions.
Once it has been placed as described above, the two jacks 11, 11 that are pivoted on the rear back side are folded, the vehicle is driven to the destination, and agricultural work is carried out at the site with the agricultural machine still mounted in the cargo box 5. . However, depending on various conditions of agricultural work, there may be cases where it is desired to replace the agricultural machine mounted on the packing box 5 with a separate working machine to perform a different agricultural work.

In such a case, the engaging metal fitting 13 and the fitting metal fitting 14
A pair of jacks 11, 11 pivotally mounted at rear right and left positions push out the cargo box 5 mounted on the chassis 3 in the direction of the arrow backward along the guide rail 6 as shown in FIG. When the cargo box 5 is raised up, the fitting locking fittings 8 and the fitting fittings 12 are disengaged, and the cargo box 5 is smoothly moved rearward.
The moment the front jack 10 setting position passes the starting end side of the guide rail 6, it automatically springs into an upright state.

After adjusting the jack 10 that is now in the upright position to make the height of the jack 10 in the forward position higher than the set height of the guide rail 6, the multi-wheeled agricultural vehicle 1 is then moved in the direction of the dashed-dotted line arrow. The chassis 3 of the multi-wheeled agricultural vehicle 1 smoothly slides out of the cargo box 6 and the two are completely separated.
This time, enter the lower part of the cargo box 5 containing another agricultural machine, and move the chassis 3 according to the same operation sequence as the first one.
By placing the packing box 5 on top, other agricultural work can be carried out in a short time. Note that if the above-described attachment/detachment operation is applied to the case where harvested agricultural products are loaded onto the packing box 5 and transported, the cargo handling work and transportation efficiency can be significantly improved.

In short, the present invention has the above-mentioned configuration, so that even when various types of agricultural work or the height of the cargo box 5 loaded with agricultural products do not match the height of the chassis 3 of the multi-wheeled agricultural vehicle 1, the extension of the jacks 10 and 11 is possible. The multi-wheel agricultural vehicle 1 can be easily matched with the adjustment operation, and the multi-wheeled agricultural vehicle 1 can be smoothly slid along the guide rail 6 and mounted directly on the chassis 3 by simply moving the vehicle backward, allowing various agricultural operations to be carried out even if the vehicle has a simple configuration. When the cargo box 5 is mounted directly on the chassis 3, it is possible to achieve this efficiently, and when the cargo box 5 is mounted directly on the chassis 3, the fitting engagement locking fittings 8 provided at the left and right rear ends of the chassis 3 and the rear position on the back side of the cargo box 5 are connected. The fitting fitting 12 provided on the multi-wheel agricultural vehicle 1 and the fitting protrusion 13 provided on the multi-wheeled agricultural vehicle 1 are automatically fitted and locked to securely lock the loading box 5. It prevents the cart from accidentally moving from side to side or back and forth, eliminates all accidents of the cargo box 5 falling off, and allows you to carry out your favorite agricultural work or work on any soft ground, sand dune, slope, or snowy ground. Not only can agricultural products be transported efficiently, but the overall structure of the device can be simplified and the cost can be reduced.
