Description

[Detailed Description of the Invention] (Background of the Invention) A soil transport device for a tractor is, for example,
As shown in Publication No. 57-41254 or Publication No. 57-26941, it has a structure in which a window is provided on the front side of the container and a plow is attached to the window, and this is attached to the rear of a tractor for towing. It was designed to scoop up soil and transport it (Figure 1). In other words, in the figure,
A is a tractor, B is a three-point link mechanism, and C is a container. A window E is opened in the front wall D of the container C, a plow F is attached to the window E, and the plow F is set by driving the tractor A to move forward. The excavated soil is flowed into the container C through the window E and transported.

This device has a snow removal blade G on the rear edge of the container C so that it can be used for snow removal by backing up the tractor A.
is formed.

The disadvantage (characteristic) of the known example in Figure 1 is that the soil scraped by the plow F is poured into the container C from above, and the subsequent excavated soil is poured in one after another so as to be piled up above the preceding excavated soil. , the container C is filled.
In order to do this, it is necessary to raise the excavated soil by the plow F to a certain height, and therefore the tractor A must be moved at a considerable speed
39282 explains that it is 40 to 50 km/h).

Therefore, the swollen and soft cultivated soil cannot flow into the container C.

FIG. 2 shows an improvement on this point, in which the plow F is attached not to the front wall D but to the bottom wall H of the container C. That is, by forming a window E in the bottom wall H and attaching a plow F to the window E, cultivated soil can be forced into the container C from below like a mole embankment. Moreover, since tractor A can be used even when moving forward at a slow speed, accurate work can be performed.

Therefore, the present invention is a further improvement of the one shown in FIG.

That is, the container C shown in FIG. 2 is provided on the front side of the tractor A so that it can be used while being backed by the tractor A.

The tractors shown in Figures 1 and 2 have to look back while driving, so before they know it, Tractor A may collide with a ridge or fall into a stream. Also, if too much soil is placed in the container C, it may spill out. This means that container C is attached to the rear of tractor A.

Therefore, in the present invention, the container C is attached to the front side of the tractor A so that the operator can work while monitoring the tractor 24/7.

The present invention provides a container in front of a tractor via a three-point linkage mechanism, a snow removal blade is formed at the frontmost edge of the bottom wall of the container, and a snow removal blade is formed on the rear side of the snow removal blade on the bottom wall of the container. The gist of this invention is a tractor transport device in which a window is provided at the front of the vehicle, and a plow is attached to the window, which is lower toward the front.

To explain with reference to the drawings, reference numeral 1 indicates a tractor, and a normal tractor or a reverse type tractor is used. 2 is a lower link, 3 is an upper link, 4 is a lift arm, and 5 is a rod. The lower end of the rod 5 is pivoted to the lower link 2, and by moving the lift arm 4 upward, the lower link 2 is moved upward. By doing so and releasing the hydraulic pressure of the lift arm 4, the lower link 2 is lowered by its own weight. 6 is lower link 2 and atsupa link 3
This is a mounting frame attached to the rear part of the container 7, and a container 7 is pivotally attached to the mounting frame 6. 8 is a bottom wall, 9 is a rear wall, 10 is a left and right side wall, and a detachable front wall is provided as the case requires. Usually, the bottom wall 8 and the rear wall 9 are fixed, but
The left and right side walls 10 can be attached to and detached from the bottom wall 8 and the rear wall 9, or can be opened and closed. A blade portion 11 is formed on the front edge of the bottom wall 8 in the left-right direction. Therefore, when the tractor 1 is moved forward, the blade part 11 can scoop up accumulated snow, or the blade part 11 can scoop up mud from a muddy mountain.
Similarly, piled compost, grass, etc. can also be scooped out by the blade part 11. A horizontal window 12 is formed immediately behind the blade part 11, and a forward facing plow 13 is attached to the horizontal window 12. The plow 13 becomes lower toward the front.

Therefore, when the container 7 is lowered and moved forward through a flat field, the soil surface is excavated by the plow 13 and the soil can be stored in the left and right side walls 10 through the horizontal window 12. During this time, the work is extremely accurate as it can be observed at all times.
