Description

[Detailed explanation of the idea] [Industrial application field] The present invention relates to an improvement of an earth crusher.

[Prior art] Conventionally, this type of earth crusher has a cylinder mounted horizontally in an inclined position so as to be rotatable with respect to the machine frame, and screening holes are provided in the cylinder with a uniform opening ratio over the entire area of the cylinder. The crushed soil is crushed by the disposed crushing body and the crushed soil is sorted and collected through the sorting hole, and foreign substances such as grass roots are discharged to the outside from the slanted lower end of the cylindrical body. In addition, as shown in Figure 1, it is proposed that the crushed earth body be lengthened in a stepless or stepped manner from the input side to the discharge side of the cylindrical body, or one in which all lengths are the same. has been done.

[The problem that the idea attempts to solve]

Another problem with the structure of the crushed earth body is that the screening holes are formed with a uniform opening ratio over the entire area of the cylindrical body. In other words, the soil input from the hopper contains not only clods but also a large amount of fine soil that is immediately sorted, but with the screening hole opening ratio of conventional machines, this fine soil cannot be immediately sorted and collected. Therefore, it is forced to flow toward the discharge side. This results in a longer residence time within the cylinder, which poses a problem of increasing the load on the drive mechanism from a weight standpoint.

The purpose of the present invention was to solve the problems of the prior art by simple yet rational means, to provide an excellent screening porosity, and to avoid placing a heavy burden on the cylindrical body. The purpose of this project is to provide a crusher that does not require

[Means to solve the problem]

The structure of the present invention, which solves the problems of the prior art, is to horizontally suspend a cylindrical body having a large number of sorting holes in an inclined position so as to be rotatable with respect to the machine frame, and the inclined upper end side of the cylindrical body is attached to the machine frame. In addition to connecting to the hopper provided in
Furthermore, in a soil crusher having a crushing rod having a crushing rod rotatably penetrated along the center axis of the cylinder, the opening ratio of the screening hole on the lump input side of the cylinder is increased, and the screening hole on the discharge side is increased. It is characterized by having a small pore opening ratio.

A large number of screening holes 9 are formed in substantially the entire area of the cylinder 6 in a grid pattern. As is clear from FIG. 1, the distance between the screening holes 9 increases as the group of screening holes 9 approaches the input side of the lump soil, specifically, from the sloped upper end of the cylinder to the sloped lower end discharge side. It is formed. That is, the density of the screening holes 9 gradually changes from dense to coarse from the upper end of the slope to the lower end of the slope. This forming method from dense to coarse can be done by changing the interval endlessly, or by dividing the cylindrical body 6 into a plurality of zones from the sloped upper end to the sloped lower end, and adjusting the distance between the screening holes in each zone.

[Effect of idea]

Since the present invention is configured as described above, the following effects can be obtained.

(a) Fine soil that does not require crushing and is contained in the clods fed from the hopper can be quickly and effectively sorted and collected on the input side of the cylinder with a large porosity, and then No weight burden.

(b) Since contaminants (foreign objects) such as stones are not sorted out and are gradually accumulated on the discharge side of the cylinder, and the rate of contact with the crushed earth body increases, the tip of the crushed earth body and the inner surface of the cylinder are If a stone or the like is caught between the cylinder and the cylinder, this impact can easily damage the cylinder, but this is because the opening ratio of the screening holes on the discharge side of the cylinder is small, that is, the distance between the screening holes is large compared to other areas. , the cylindrical body strength of the relevant part is high, and it is not easily damaged like in the past.
Will not be damaged.
