Description

DETAILED DESCRIPTION OF THE INVENTION The present invention seeks to provide a reverse crushing earth shaking screen fertilization and seeding rotor having a novel configuration.

Reference numeral 1 is a reverse crushed soil shaking screen fertilization and seeding rotor of the present invention.

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 above 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 stretched from above to the rear side of the rotor 4. A regulating plate 9 is installed behind the sieve body F at a predetermined distance from the sieve body F, and a pressure plate 10 is connected to the lower end of the regulating plate so as to constantly press it downward. On the other hand, a fertilizer hopper 11 and a seeding device 1 are installed in front and rear positions above the regulating plate.
2 is provided, and a guide pipe 11 from the hopper 11 is provided.
A is suspended behind the sieve body F, and a seeding guiding pipe 12A from the seeding device 12 is suspended slightly below the pin P.

Therefore, the rotor 4 is attached below the cover-like frame 3, which is attached in a direction perpendicular to the direction in which the frame 2 moves.

Further, inside the cover-like frame, a rubber cover 5 is provided which covers the front side of the rotor 4 from above.
has a substantially square cross-section, and the upper part on the rear side of the cover is connected to the lower surface of the cover-shaped frame 3 via a spring 5A or a cushion, and the lower part on the front side is connected to the lower surface of the frame 2. It is connected to the cover-shaped frame 3 via a spring 5A' such as a coil spring with a lower position on the traveling direction side, and a projecting edge 5B extending slightly rearward is connected to the upper part of the cover. The projecting edge may be constructed so that the support angle can be adjusted using a bolt 5C that can be raised and lowered from above.

Furthermore, the structure of the sieve body F is 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 on the horizontal rod 2B stretched on the horizontal rod 2B, and a fixed grid arranged between the fixed grids 7 has the same shape as the fixed grid. The upper end of the swing grid 8 is configured to be forcibly swung by an appropriate power via a connecting metal fitting 13.

Therefore, this swing grid 8 is connected to an output shaft 20 via a connecting rod 8A, a connecting hardware 13, a shock absorber 14, and a crank 15.

This buffer device 14 is connected to the connecting hardware 13.
A shaft 14B from the crank 15 is inserted into the vertical plate of the U-shaped frame 14A which is connected via a pin P to the shaft 14B, and front and rear coil springs 14C and 14D are attached to the shaft 14B, centering on the frame 14A. .

14C' and 14D' are washers.

As a result, when the crank 15 moves forward due to the rotation of the output shaft, the shaft 14B is pulled forward.

At this time, the rear coil spring 14D is temporarily compressed, and when the shaft 14B moves rearward, the front coil spring 14C is temporarily compressed.

By repeating such actions, the rotational force from the output shaft can be transmitted to the oscillating grid while being buffered.

The regulating plate 9 and the suppressing plate 10 are connected by a pin P, and are configured to be constantly pressed downward by a downwardly acting spring 9A having a fulcrum on the regulating plate 9.

As shown in FIG. 11, this pressing plate 10 is provided with a curved portion 10A having a substantially inverted U-shape on the back surface and forming ridges.

12B is an opener connected to the lower end of the seeding guide pipe 12A, and the seeds fall through this opener.

In this case, this opener 12B is the pressure plate 10
It penetrates from above, and its lower end is opened in the space of an inverted U-shaped curved portion 10A provided on the suppressing plate 10.

This opener can also be adjusted up and down.

13' is a tail wheel, and 21 is an iron wheel connected as necessary.

As shown in FIG. 9, the frame 2 is attached to a support rod 19 that is swingably erected on the upper surface of the cover-like frame 3.
It may be configured such that a coil spring 19A is applied between the cover-like frame 3 and the cover-like frame 3 to act downwardly with a predetermined pressure.

Furthermore, as shown in FIG. 10, the arm 2A to be connected to the hitch of the tractor can be configured to be reversible in the front and back direction with respect to the pipe-shaped horizontal frame 3A attached to the top of the cover-shaped frame 3 and the transmission case 3B. can.

Since the direction of movement is reversed by reversing the arm, the transmission case 3B is also provided with an input shaft 3B' projecting in the front-rear direction.

22 is a seed, 16 is a coarse soil layer, 17 is a fine soil layer, and 18 is a 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.

This sieve body then sieves the material, but the soil that is too large to pass through the sieve body falls to the front, and the fine 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 9 and falls.

As a result, large soil that cannot pass through the sieve forms a coarse soil layer 16, and fine soil that passes through the sieve forms a fine soil layer 17 on top of this.

In this case, since the sowing guide pipe 12A is provided behind the regulating plate 9, the seeds 2 from the sowing machine can be
2 falls into the ground as an opener.

The fine earth and sand guided along the lower surface of the regulating plate 9 and the suppressing plate becomes the soil covering layer 18 and is scattered over 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.

Moreover, when the earth and sand crushed by the earth crushing rotor hits the cover, since the cover is supported by a spring, it vibrates, thereby preventing the phenomenon of adhesion of earth and sand.

In addition, since the projecting edge portion 5B is raised and lowered by raising and lowering the bolt 5C, it is possible to adjust the soil scattering angle from the rotor.

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.

That is, since the pressing plate 10 is configured to be constantly pressed downward by the spring 9A as described above, it performs a soil-covering action.

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