を示している。 1 is the proposed agricultural soil processing machine. The structure is such that a shaft 3 is installed below a frame 2 which is located at the rear of a tractor or a tailor and is configured to be towed, in a direction perpendicular to the direction of movement of the tractor. A chain drive is used to reverse the direction of movement of the tractor, etc., and a machete 4 for crushing soil is planted, and a cover 5 made of a rubber plate having a substantially square cross section is stretched over the top surface of the shaft. At the same time, a sieve body 6 in which fixed frames 6A and swinging rods 6B are alternately arranged in a lattice pattern is installed on the rear edge of the cover, and a chain for operating the shaft is attached to the swinging rods of this sieve body. It is configured to be connected with a chain tension 8 and a connecting rod 9 to provide vibration. Therefore, the connecting rod 9 consists of a lower rod 9A and an upper rod 9C connected to this lower rod with a pin 9B,
The lower rod is tensioned by the chain 8 with spring 9D.
is drawn so that it is always in contact with the chain. 6B' is an arm fixed to the swinging rod. In the figure, 2A is a cover made of iron plate, 2B is a rubber saucer, 2
C indicates the tail wheel, 2D indicates the hitch, and 2E indicates the drive joint case between the main body and the rotor. 5 and 6 show the center drive type, and FIGS. 7 and 8 show the side drive type.

調整できることが示されている。 As shown in FIGS. 9 and 10, the above-mentioned mechanism may be attached to a structure 11 in which a rotor 11A is horizontally suspended on the front surface of the shaft 3. Regarding this rotor, there is a screw-shaped rotor 11A' as shown in FIG. 11, a rotor 11B with an inclined disk or square disk attached as shown in FIG.
It may also be a type 11C in which small plates are implanted as shown in Figure 6.
In addition, in FIG. 10, a turnbuckle 9C' is provided on the upper rod 9C to connect the lower rod 9A and the arm 6.
It is shown that the pressing force of the chain tension 8 on the chain can be finely adjusted by finely adjusting the distance between B' and by connecting the outer end of the spring 9D to the screw 9E that moves back and forth. .

バーへの土の付着を防止することができる。 Since the proposed proposal is structured as described above,
Vibrations due to the unevenness of the driven chain 7 are transmitted to the chain tension 8, and are transmitted via the connecting rods 9 to the swinging rods 6B of the sieve body. As a result, since the swinging rod vibrates minutely between the swinging rod and the fixed rod, clogging caused by earth and sand scraped up by the reversing machete 4 is prevented. In addition, crushed soil larger than the gap between the fixed rod and the swinging rod of the sieve body falls on the front side of the sieve body, and crushed soil smaller than the gap between the sieve body falls to the rear through the gap between the sieve body. As a result, coarse crushed soil is layered at the bottom and fine crushed soil is layered at the top. Moreover, the crushed soil scraped up by the reversing machete advances along the lower surface of the cover 5 and reaches the sieve body. In this case, since the rear end of the cover 5 is connected to the swinging rod,
Since the vibrations of the swinging rod are also transmitted to this cover, it is possible to prevent soil from adhering to the cover.
