The structure is such that a crushing rotor 4 is attached to a frame 2 that is configured to be towed by a tractor or the like so that the rotor 4 has a direction of movement of the frame and is reversed with respect to the front side, which is the direction of movement of the frame. A vibrating rubber cover 5 is stretched from the top to the front side, and a sieve body F consisting of a fixed grid 7 and a swinging grid 8 that swings between the fixed grids is installed from the top to the rear side of the rotor 4. A regulation plate 19 is swingably provided behind the sieve body F at a predetermined distance from the sieve body F, and an opening 19A is formed above the regulation plate. , an adjustment plate 19B for adjusting the flow rate of the covering soil is provided in this opening 19A, and the regulation plate 19
A seeding pipe 20 is suspended behind the seeding pipe. Therefore, the rotor 4 is connected to the frame 2.
The cover-shaped frame 3 is attached below the cover-like frame 3, which is attached in a direction perpendicular to the direction of movement of the cover. Further, inside the cover-shaped frame, there is a rubber cover 5 that covers the front side of the rotor 4 from above, and the cross section is omitted.
The upper part on the rear side of the cover is connected to the lower surface of the frame 3 via a spring 5A or a cushion, and the lower part on the front side is located at a lower position in the traveling direction of the frame 2. The cover is connected to the cover-shaped frame 3 via a spring 5A' such as a coil spring, and the cover has a projecting edge 5 extending slightly rearward at the top of the cover.
B are connected to each other, and this projecting edge is configured so that the support angle can be adjusted by a bolt 5C that can be raised and lowered from above. Furthermore, the structure of the sieve body F is such that the horizontal rods 2B are stretched over the side plates 2A of the frame 2.
A fixed grid 7 is stretched at a predetermined interval so as to cover the rear side of the rotor 4 from above, and a swinging grid 8 is disposed between the fixed grid 7 and has the same shape as the fixed grid. The upper end of the grid 8 is configured to be forcibly swung by an appropriate power via a connecting metal fitting 9. Therefore, this swing grid 8 is connected to an output shaft 14 via a connecting rod 8A, a connecting hardware 9, a shock absorber 10, and a crank 11. This device 10 includes a U-shaped frame 10 connected to the connecting hardware 9 via a pin P.
A shaft 10B from the crank 11 is inserted into the vertical plate of A, and the frame 10 is inserted into this shaft 10B.
Front and rear coil springs 10C, 10 around A
D is attached. 10C' and 10D' are washers. As a result, when the output shaft rotates and the crank 11 moves forward, the shaft 10B is pulled forward. At this time, the rear coil spring 10D is temporarily compressed, and when the shaft 10B moves rearward, the front coil spring 10C is temporarily compressed. By repeating such actions, the rotational force from the output shaft can be transmitted to the oscillating grid while being buffered. Regarding the operation of the oscillating grating relative to the fixed lattice, as shown in FIG. However, as shown in FIG. 8, the drive from the crankshaft 8C is transmitted to the one side grid 8D through the link 8B by the gear 8D', and the drive from the other side is transmitted through the gear 8E' meshing with this gear 8D'. Even if the grids 8D and 8E are configured to swing alternately by being connected to the grid 8E, as shown in FIG.
Even if the grating 8 is configured to swing by transmitting the signal B to a swinging rod 8F pivotally attached to the side plate 2A and connecting the swinging grating 8 to this swinging rod, as shown in FIG. A connecting plate 8G is connected to the upper end of the swing lattice 8, and front and rear metal fittings 8H are separately fixed to the frame 2 side with a predetermined distance from the connecting plate 8G. Even if the structure is such that the grid 8 is swung using vibration by placing a spring 8H' between them, as shown in FIG.
is similar to the above, but the movement of the connecting plates is connected to the gratings 8D, 8 through gears 8D', 8E' that mesh with each other.
Even if the structure is configured so that the signals are transmitted to E and swing each other, as shown in FIG. Tell the lifting rod 8I′ to
It may be configured such that the lattice 8 connected above the lifting rod is swung. On the other hand, a connecting rod 19C is connected to the upper end of the regulating plate 19, and this connecting rod is connected to a metal fitting 19E fixed to the frame 2 side via a spring 19D stretched in the front-rear direction. Further, the tip of the adjusting plate 19B is inserted into the opening 19A and connected to the regulating plate by a pin 19F, and a turnbuckle 19G is stretched between the lower surface of the rear end of the adjusting plate and the regulating plate. Therefore, by expanding and contracting this turnbuckle, the support angle of the adjustment plate can be adjusted. 1
9G' is a lid that opens and closes the opening 19A,
The degree of opening can be adjusted by raising and lowering this lid. 20A is a sowing device, 21 is a cover provided above the rear of the regulation plate 19, 22 is a suppression plate connected to this cover 21, 23 is a suppression wheel, 24 is a tail wheel, 2
5 is a material hopper, 25A is a guide pipe, 26 is a speed reducer, 27 is a seed, 28 is a coarse soil layer, 29 is a fine soil layer, and 30 is a soil covering layer.

Next, the operation of the present invention will be explained together with the effects.

The earth and sand crushed by the earth crushing rotor hits the cover 5 and is blown toward the sieve body while being guided by the cover 5. Sediment that is too large to pass through the sieve body falls to the front, while fine-grained soil falls to the rear of the sieve body. The earth and sand that has passed through the sieve body in this way is guided by the regulating plate 19 and falls, but some of it passes through the opening 19A and is blown backward. As a result, large soil that cannot pass through the sieve forms a coarse soil layer 28, and fine soil that passes through the sieve forms a fine soil layer 29 on top of this. In this case, since the sowing guide pipe 20 is provided behind the regulating plate 19, the seeds 27 from the sowing device fall and are deposited on the seeds 27 at the opening 19A.
The soil that has passed through becomes the soil covering layer 30 and is scattered on the upper surface of the seeds. In this case, since the sieve body consists of a fixed grid and a swinging grid, clogging phenomenon can be prevented. Further, since the opening 19A is provided with an adjusting plate 19B whose angle can be freely adjusted, the flow of the amount of soil covered can be adjusted as appropriate. Further, when the earth and sand crushed by the earth crushing rotor hits the cover, the cover vibrates because it is supported by a spring, so that the phenomenon of adhesion of earth and sand can be prevented. In addition, the above bolt 5C
Since the projecting edge portion 5B is raised and lowered by raising and lowering the rotor, the soil scattering angle from the rotor can be adjusted.
Furthermore, since the fertilizer hopper conduit pipe 25A is provided in front of the soil crushing rotor, fertilizer can be spread before the soil crushing operation.

As described above, the present invention can be said to be a useful invention that can perform a series of soil crushing, sowing, and soil covering operations reliably and quickly while achieving the following items.

That is, large soil that cannot pass through the sieve becomes a coarse soil layer 28, and fine soil that passes through the sieve forms a fine soil layer 29 on top of this, making it possible to create a field with an ideal cross section.

Since the earth and sand that has passed through the opening is spread over the top surface of the fallen seeds as a soil cover layer 30, the work can be done in an extremely labor-saving manner.

Since the sieve body consists of a fixed grid and a swinging grid that swings relative to the fixed grid, clogging can be prevented.

The opening 19A has an adjustment plate 1 that can be freely adjusted in angle.
Since the 9B is provided, the flow of the amount of soil covering can be adjusted appropriately, so the work can be performed optimally depending on the field conditions.

In addition, the product of the present application can pull the remaining barley and rice stalks and rice plants that remain after harvesting into the ground, and also exerts the action of pulling rice plants when used for puddling. Become.
