Description

DETAILED DESCRIPTION OF THE INVENTION FIG. 1 shows the generally implemented prior art to which the present invention is directed. In FIG. 1, A is a rectangular container, and the container A has a vertical front wall a. , vertical left and right side walls b, vertical rear wall C, horizontal bottom wall d
It is formed by a tractor and is towed in the direction of arrow A.

B is a vertical opening provided in the front wall a, and C is a hawk body that is attached to the front side of the opening B and digs up the topsoil of the field.

Its action is that when the container A is attached to a tractor and pulled through the field, the topsoil is scraped by the flower body C attached to the front side of the opening B, and the scraped soil flows into the container A from the opening B.
When Container A is full, it travels to a lower part of the field, dumps it, and embanks it.

The drawbacks of the known example shown in Fig. 1 are that it cannot be used when the topsoil of the field is soft, that it is difficult to use because it does not work unless it is pulled at a considerable speed, and that it cannot scrape all the way to the corners of the field.

In other words, the soil scraped by Hayabusa C is lifted up to opening B and thrown into container A, so in the case of a field before cultivation, the scraped soil forms a continuous soil lump and is conveniently placed. It flows into container A, but in a field after cultivation, the soil is soft, so
It does not become a continuous lump of soil, that is, sludge, and is not guided as shown in Figure 1.

In addition, as shown in Figure 1, in order to guide the clod with container C, the tractor must move forward at a considerable speed, but if the speed of the tractor is too fast, the clod will jump over container A due to excessive force. I end up.

Furthermore, since the projectile body C protrudes forward from the front wall a, only the protruding portion cannot be excavated.

Therefore, in the present invention, a horizontal opening is formed in the bottom wall of a rectangular container consisting of a front wall, left and right side walls, a rear wall, and a bottom wall, which communicates the outside of the container with the inside of the container. , a green body is attached to the lower side of the opening, which is lower towards the front, and the shape of the firing body when viewed from above is formed into a symmetrical approximately triangular shape with a pointed front end in the center; The front end of the container is designed not to protrude further forward than the front wall, and the gist of the device is to connect such a container to the rear of a tractor by a well-known connecting means.

To explain this with reference to the drawings, reference numeral 1 denotes a container towed by a traveling vehicle in the direction of arrow A, with a vertical front wall 2, vertical left and right side walls 3, 4, a vertical rear wall 5, and a horizontal bottom wall 6. It is usually formed without a lid (earth wall).

The front wall 2 is fixed to the bottom wall 6 and cannot be opened or closed, but the left and right side walls 3, 4 and the rear wall 5 are pivoted so that they can be opened and closed (not shown). In the case of the known side shown in the figure, a vertical opening B was formed in the front wall a, but
The opening I in the present invention is horizontal, and the horizontal bottom wall 6
It is installed in a part of.

That is, a horizontal opening 7 that communicates the lower outside of the container 1 with the inside of the container 1 is formed in the front part of the central part of the bottom wall 6, and from the rear edge 8 part of the horizontal opening I, the horizontal opening 7 is formed. Attach the Hayabusa body 9 which becomes lower as it goes.

The housing 9 has a sharp shape with its central front end protruding most forwardly, and the width increases toward the rear so as to take on a symmetrical triangular shape.

The frontmost end of the housing 9 does not protrude further forward than the front wall 2.

Therefore, when towed by a tractor, the front wall 2 moves forward until it reaches the ridge as the tractor pulls it over the ridge.

Therefore, when comparing the known example shown in FIG. 1 with the one of the present invention, there are differences in the position of the opening, the position of the blade, and the size of the blade. There are also significant differences as shown below.

(1) Since the horizontal opening 7 is much lower than the vertical opening B of the known example, the height required to lift the soil is low, and therefore, even swollen and soft cultivated soil immediately after tilling can flow into the container 1. I can do it.

(2) Due to the configuration described in the previous item (1), the Hayabusa body 9 is
It can be made overwhelmingly smaller compared to .

(3) As is clear from the comparison between FIG. 1 and FIG. 2, according to the present invention, the soil can be scraped until the two portions of the front wall reach the ridge.

The one in Figure 1 cannot be expected because there is a falcon body C in front of the anterior wall a.

(4) In the model shown in Fig. 1, the action is to throw the excavated soil lifted by the projectile C into the container A, so it does not work unless the tractor moves forward at a predetermined high speed. Because the soil is forced into the container 1 through the opening 7 at the bottom and stored therein, the container 1 can move forward at an extremely slow speed.

Therefore, work can be done accurately.
