Description

[Detailed description of the invention] (Industrial application field) The invention is used in a soil cultivation device for agricultural machinery, and in particular, a guide tube is suspended from the feeding part of a supply tank arranged above a float, and the guide tube is A trenching body is installed at the bottom, and a soil plate is installed at the rear of the trench.
The present invention relates to a specific structure of a soil cultivating device that backfills soil using the soil plate into a groove that has been cut by the trench cutting body and has been sown or fertilized.

(Prior Art) The tilling plate in the above-mentioned tilling device which is conventionally used is configured so that the flat plate body is tilted backwards and the whole is tilted with respect to the direction of propagation so as to fill the seeding groove with soil.

(Problem that the invention aims to solve) However, this method does not backfill the rice seeds in the sowing furrow with soil from above, but instead presses the sowing furrow from the sides and fills the soil all at once. There was a fear that the seed rice would be pushed out. As a result, the seed rice floats and the sowing depth becomes unstable.
This resulted in defects such as poor seedling growth and tendency to lodge.

The technical problem of this invention is to move the mud on the sides of the trench where seeds are sown or fertilized to the trench side without forcibly pressing the trench, and to fill the trench sequentially from above with the mud on the surface in advance. In this way, it is an object of the present invention to provide a specific structure of a soil cultivation device that can prevent seeds and fertilizers from floating up and keep the depth of sowing or fertilization constant.

(Technical means for solving the problem) In order to solve the above-mentioned problem, the soil cultivation device for the agricultural machine according to the present invention has a guide tube hanging down from the feeding part of the supply tank arranged above the float. In an agricultural machine that is provided with a groove-forming body at the lower front and a soil plate behind the groove-forming body and the guide tube, the soil plate is formed by forming a groove along the field surface with a gap above the lower surface of the float. At the same time, a bend is formed on the flat side, the forward sloped side in front of the flat side, and the backward downward sloped side at the rear of the flat side, and the backward downward slope is formed on the outside of the seeding or fertilization groove made by the groove making body. It is characterized in that the front end of the side is disposed, and the rear end of the sloped side is provided obliquely with respect to the traveling direction so that the rear end of the sloped side faces the groove.

(Function) As the aircraft moves forward, the muddy soil near the outside of the trench to be sown or fertilized is guided by the forward sloped side and flat side of the soil plate, and the muddy soil on the upper surface is guided back into the trench to be sown or fertilized, and the seeds are After stabilizing the soil and fertilizer at a predetermined depth, the final soil is placed on the sloped side.

(Example) To explain the configuration of the present invention with reference to an example shown in the drawings, the one shown is a submerged soil seeding machine,
This seeding machine has an engine 2 mounted on the front part of a traveling body 1, and wheels 4 for propulsion of the machine are supported on both left and right sides of a transmission case 3 in the center so as to be movable up and down via a swing case 5. A sowing unit 8 consisting of a tank 6 for storing rice seeds and a sowing drive mechanism 7 interlocked with the transmission case 3 is attached to the rear of the machine, and a steering handle 9 is extended to the rear of the sowing unit 8. There is a central float 10 in the center below.
a, Side floats 10b, 10b are arranged on both sides.

A guide tube 11 is vertically installed below the tank 6, and the floats 10a and 10b are each provided with a receiving gutter 12 corresponding to the guide tube 11. A conduit 13 fitted onto the guide tube 11 is interposed therebetween.

A groove-making piece 14 is provided at the ground contact point in front of the conduit 13, and a cultivating soil plate 15 and a soil covering plate 16 are provided at the rear of the receiving gutter 12 for each sowing row (four rows in this embodiment).
The seed rice stored in the tank 6 is sequentially delivered in a predetermined amount by the rotation of a delivery device 17 provided in the tank 6 as the machine travels, passes through a guide tube 11, a conduit 13, and a receiving gutter 12, and is formed by a groove piece 14. After falling into the trench in the soil, the subsequent soil plate 15 and soil covering plate 16
The seeds are being sown and covered with soil in sequence.

The tank 6 is fixed to the traveling body 1 via a horizontal stay 18, and floats 10a, 10b
The rear part is pivoted to the traveling body 1, and the front part can move up and down to slide on the rice field.

At the rear of each of the floats 10a and 10b, a recess 20 is formed which is bifurcated in plan view and open at the rear, as shown in FIG. A base 12a portion of the formed receiving gutter 12 is attached.

As shown in FIGS. 7 and 8, the soil plate 15 has a flat side 15b along which the body is placed along the field surface with a gap above the lower surface of the float, an upwardly sloping side 15a in front of the flat side 15b, and a flat side 15b. A mounting portion 25 is formed by bending the rear downwardly inclined side 15c and protrudes upward from the upper surface of the flat side 15b.
It is screwed onto the base 12a of the receiving gutter 12 via a screw. Then, the front end of the downwardly downwardly inclined side 15c is arranged on the outside of the seeding groove formed by the groove forming piece 14,
The rear end of the inclined side 15c faces the seeding groove, and the downwardly downward inclined side 15c is aligned in the machine traveling direction (seventh direction).
It is installed obliquely with respect to the direction (parallel to X-Y in the figure). Therefore, the front upwardly sloped side 15a can be arranged so as to form a gap substantially parallel to the opposing float side wall, and there is no possibility that mud will accumulate in between.

In addition, the flat side 15b has a gap above the lower surface of the float so as to follow the field surface, and is made wider at the front and narrower toward the rear. It becomes easier to slide down the flat side 15b, and the entire soil plate 15 has a streamlined shape, resulting in less mud resistance and better flow.

The soil covering plate 16 provided at the rear of the soil plate 15 has its tip base screwed to the base 12a of the receiving gutter 12, and a rubber plate 16a for leveling the ground is provided at the lower end. .

The present invention is configured as described above, and the power of the engine 2 is transmitted from the mission case 3 to the feeding device 17 via the seeding drive mechanism 7.
As the traveling machine 1 moves, the seed rice stored in the tank 6 is fed out from the guide tube 11 by a predetermined amount through the conduit 13 from the receiving gutter 12 to the seeding groove formed by the groove forming piece 14. fall inside.

Then, the upper layer of mud near the sides of the seeding groove is guided by the front upwardly sloping side 15a of the soil plate 15 and slides below the flat side 15b. At this time, the front-sloping side 15a is slanted forward with respect to the direction of travel, so that the mud is smoothly guided to the rear, and the tip of the flat side 15b extends widely to the outside of the seeding groove, and Since the lower surface of the flat side 15b is above the lower surface of the float, the guided mud smoothly slides below the flat side 15b.

Since the rear downward slope side 15c is inclined so that the rearward side is closer to the seeding groove, the mud that has slipped below the flat side 15b is moved toward the seed groove by the rear downward slope side 15c, and the seed groove is backfilled sequentially from above. , the soil is in good condition at the rear end of the soil plate 15. That is, as the aircraft 1 advances, the soil plate 1
5 progresses, mud is guided below the flat side 15b, and it becomes filled with mud as described above.

When this happens, the mud trying to slide from the upward slope side 15a to the flat side 15b is no longer able to slide and is instead pushed out toward the seeding furrow, creating a situation similar to waves rolling backwards, and the relatively soft mud on the surface The trench is backfilled little by little from above so as to cover the seed rice, and the seed rice is buried at a predetermined depth. Thereafter, the mud on the side surfaces of the groove is collected using the rear downward slope side 15c to cultivate the seeding groove.

At this time, the seeding trench is backfilled one by one without being filled with soil from the sides all at once by the soil plates 15, so the seed rice in the trench is not pushed out or floated up, which will prevent the seeding depth from becoming unstable.

The upper surface of the seeding groove filled with soil by the soil plate 15 is leveled by the rubber plate 16a of the soil cover plate 16 provided at the rear.

Although the present invention has been described in the case of a seeding machine, the same effects can be obtained even when the present invention is applied to a fertilizer applicator such as a granular fertilizer applicator.

(Effects of the invention) The present invention is particularly advantageous in forming the soil plate 15 by forming a flat side 15b along the field surface with a gap above the lower surface of the float, an upwardly sloped side 15a in front of the flat side 15b, and the above-mentioned flat side 15b along the field surface. The rearwardly downwardly inclined side 15c at the rear of the flat side 15b is bent, and the front end of the rearwardly downwardly inclined side 15c is arranged outside the seeding or fertilizing groove formed by the groove-making body, and the inclined side is bent. Since the rear downward slope side part is provided diagonally with respect to the traveling direction so that the rear end part of 15c faces the groove part, the mud on the side of the groove to be sown or fertilized is guided by the front upward slope side 15a, and the flat side 15b In addition to making it slide smoothly downward, the terminal end of the rear downward slope side 15c, which is inclined with respect to the direction of travel, faces the groove for sowing or fertilizing, so that the front upward slope side 15a and the flat side 15b are The muddy soil on the surface is gradually brought into the groove and the groove is backfilled sequentially from above, and then the sloped side 15c at the back is used to ensure that the soil is cultivated. This prevents the seeds and fertilizers in the furrow from floating up or making the depth of sowing or fertilization unstable by pressing the soil all at once.
This has made it possible to always maintain a constant seeding and fertilization depth.
