While an intermediate part of a control lever 9 is pivotally supported through a hinge 8 to the upper side of a U-shaped metal fixture 7 secured to the upper end center in a vertical part of the frame 3, and a stopper plate 12 stopped to and detached from a receiving metal fixture 15 provided to an upper face in a vertical part of the frame 4 is provided to a point end of said lever 9. Then a load bed 16 in the above constitution is mounted to a tractor through a three-point link by plural pins 6 provided to the frame 3.

Description

DETAILED DESCRIPTION OF THE INVENTION The present invention provides composting,
Related to loading platforms for transporting fertilizers, etc. 0 Conventionally, when using a tractor to transport compost and fertilizers, a two-wheeled trolley is used to transport it, and loading and unloading onto and off the two-wheeled trolley is carried out. It took a lot of time and effort to do so, and four-wheeled carts also had drawbacks such as being expensive to purchase.

In order to solve the above-mentioned drawbacks, the present invention has a support frame having a side view type, and an under frame having a side view type, which is pivotally attached to the side view type support frame so as to be rotatable rearward, and the upper end is locked with a locking rod. , a loading platform in which a support frame is supported by a three-point link of a tractor,
It is characterized in that it is supported by a three-point link during transportation and is allowed to land on the ground during loading and unloading, thereby saving labor.

Hereinafter, the present invention will be explained in detail with reference to embodiment figures.

A support frame 3 is formed by connecting the upper and lower ends of the vertical parts of a pair of left and right L-shaped rods 1.1 with horizontal rods 2.2, and the front and rear, left and right widths of the support frame 3 are wide. The front part of the underframe 4 is mounted on the upper surface of the support frame 3, and hinges 5, 5 are provided on the lower surface of the front part of the underframe 4 to pivot the rear ends of the L-shaped rods 1, 1 of the support frame 3. A pin 6.6 for attaching the lower link of the tractor is protrudingly provided at the center position on both sides of the vertical part of the support frame 3, and a U for attaching the upper link is provided at the front center of the upper end of the vertical part of the support frame 3. The molded metal fitting 7 is tightened and the pin 6 is inserted, a hinge 8 is provided on the upper surface of the U-shaped metal fitting 7, and the lower surface of the operating lever 9, which is bent into a V-shape, is pivotally connected, and the supporting frame 3 is attached. A plate piece 10 is installed diagonally upward from the center of the upper end of the vertical part of the underframe 4, a long hole is drilled in the center of the plate piece 10, and the plate piece 10 is pivoted to a hinge 11 on the upper surface of the rear end of the long hole. The triangular locking plate 12 is loosely fitted, and the front end of the triangular locking plate 12 is loosely attached to the bifurcated arm rod 13 at the rear end of the operating lever 9.
A spring 14 is stretched between the inner lower surface of the L-shaped metal fitting 7, and a receiving metal fitting 15'f is attached to the center position of the upper surface of the vertical part of the underframe 4, and the lower end of the triangular locking plate 12 is removably engaged. It is made to constitute a loading platform 16. In addition, 17 in the figure
indicates the tractor, and 18.18' indicates the three-point hitch of the tractor.

Next, the effects of the present invention will be explained with reference to embodiment figures.

In the loading platform 16 according to the present invention, an upper link 18 protruding from the rear of the tractor 17 is attached to a pin 6 of a U-shaped metal fitting on the front surface of the upper end of the support frame 3, and a pair of lower links 181 are attached to pins 6 and 6 at the center of both sides of the support frame 3. It is connected to and supported by.

When transporting compost, fertilizer, etc., the driver of the tractor 17 lowers the upper link 18 and lower link 18' to land the loading platform 16 on the ground, loads it onto the top surface of the underframe 4, and then lowers the upper link again. 18 and lower link 1
81 is raised, the loading platform 16 is supported at an appropriate height, and the tractor 17 is driven to transport the truck to a desired location. When unloading the compost or fertilizer loaded onto the loading platform 16, the driver of the tractor 17 lowers the upper link 18 and lower link 18' to land the loading platform 16 on the ground, and in this state, moves the front end of the operating lever 9 to the first position. As shown in FIG. 6, by pressing downward against the elasticity of the spring 14, the triangular locking plate 12 at the rear end is rotated upward around the hinge 11 at the rear end, and the receiving bracket 15 of the underframe 4 is rotated. When the support frame 3 is further disengaged and the support frame 3 is raised, the underframe 4 tilts and rotates rearward about the pivot point with the support frame 3, and the conveyed object automatically lands on the ground. After loading and unloading, tractor 1
7 is moved forward a little and the loading platform 16 is landed on the ground, the underframe 4 which had been rotating backward returns to the front and supports the support frame 3.
The receiving metal fitting 15 at the upper end is again locked by the lower end of the triangular locking plate 12, and the conveyor is moved to the next conveyance operation.

Therefore, the loading platform 16 according to the present invention can be raised and lowered using the three-point linkage of the tractor, and can also be rotated backwards by unlocking the underframe, thereby saving time and effort in loading and unloading objects. It has the remarkable effects mentioned above, such as being inexpensive to manufacture compared to two-wheeled carts, and being able to be easily installed and removed as a tractor attachment to improve the efficiency of transport work. be.
