DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a ridge forming apparatus, and more particularly to a ridge forming apparatus for forming seeds such as rice paddy and vegetable seeds in paddy fields and fields.

[0002]

2. Description of the Related Art Conventionally, as a ridge forming apparatus of this type, for example, a rotary tilling body is rotatably provided on a machine frame, and a transmission case and a bracket are provided on the left and right portions of the machine frame in a rearward direction. A rotating shaft is rotatably mounted between a bearing protruding from the rear end inside of the transmission case and a bearing protruding from the rear inside of the bracket. A structure in which a large number of large-diameter drainage groove molded bodies are fixed at predetermined intervals, and a large number of small-diameter seeding groove molded bodies are fixed to the rotating shaft between the drainage groove molded bodies. There are things. A deep drainage groove having a substantially V-shaped cross section is formed by each of the drainage groove molded bodies, and a shallow seeding groove having a substantially V-shaped cross-section is formed above the ridge between the drainage grooves by each of the seeding groove molded bodies. Is to be molded.

[0003]

In the above-mentioned structure, the large-diameter drain groove formed body and the left and right transmission cases and the brackets disposed at the left and right ends of the rotating shaft have a space corresponding to the length of the bearing body. Because they are arranged at a distance ,
Form a ridge in the next process adjacent to the ridge formed in the previous process
If the by lower end portions of the left and right of the transmission case and the bracket progresses located on sowing groove you adjacent which are ridges formed in the previous step
So that it can be molded in soft or uneven areas in the field.
The right and left transmission cases and
And the bracket descends from a predetermined position , and at the lower end of the transmission case and the bracket, the adjacent shallow seeding groove formed by ridges in the previous process may be damaged. There is a problem that it is not preferable.

The present invention has been made in view of such a point, and the inner portions of the bearings provided on the transmission case and the bracket are securely provided on the outer portions of the drainage groove formed at the left and right ends. Therefore, the left and right transmission case and brackets can be disposed close to the left and right transmission case moldings and the left and right transmission case and bracket at the time of the ridge forming work after the second stroke. Part is displaced from the position on the adjacent shallow seeding groove that was ridged in the previous step, and the lower end of the transmission case and bracket did not damage the adjacent shallow seeding groove that was ridged in the previous step. It is an object of the present invention to provide a preferable ridge forming apparatus for continuously forming grooves.

[0005]

The ridge forming apparatus of the present invention comprises:
A machine frame having a mission, a rotary tilling body rotatably provided on the machine frame and rotatably driven by an output from the mission, and protruding rearward from the machine frame to each rear end. Left and right transmission cases and brackets having bearings, and rotatably provided between the bearings of the transmission case and the bearings of the brackets located behind the rotary tilling body and rotationally driven by the output from the transmission. Ridge molded body,
The ridge formed body has a rotating shaft that is rotatably supported by the left and right bearing bodies, and a large number of large-diameter drain groove formed bodies are provided on the rotating shaft at predetermined intervals in the axial direction.

Defines an accommodation recess for accommodating the left and right bearing bodies.

[0006]

In the ridge forming apparatus of the present invention, when the machine frame is towed and the mission of the machine frame is operated, the output from the mission drives the rotary tilling body and the ridge formed body to rotate. The soil in the field is sequentially plowed and crushed by the rotary tilling body, and the cultivated soil is ridge-formed by the ridge formed body. That is, a deep drain groove is continuously formed in each V-shaped section of the ridge formed body in a substantially V-shaped cross section, and a shallow seeding groove is formed in each V-shaped section of the ridge formed body with a substantially V-shaped cross section. It is continuously formed in a shape.

[0007] At this time, the ridge formed body having each drainage groove formed body and each seeding groove formed body is driven to rotate by the output from the mission, so that each drainage groove formed body and each seeding groove formed body is cultivated soil. , So that each of the deep drain grooves and the shallow seeding grooves are formed neatly, and the soil is prevented from adhering to the respective drainage groove moldings and the respective seeding groove moldings. .

Next, at the time of the ridge forming operation after the second stroke in which the direction is changed, deep drain grooves are continuously formed in each drain groove forming body of the ridge forming body in a substantially V-shaped cross section as in the case of the previous step. While being formed, a shallow seeding groove is continuously formed in a substantially V-shaped cross section in each seeding groove formed body of the ridge formed body. During each stroke of these has a lower end portion of the heat dynamic case and the bracket that Jikuka ribbed moldings, drains left and right end portions from a position of shallow seeding-groove adjacent which are ridges formed in the previous step Ru is traveling at a position deviated to the side portion of the green body-side. And this next
During ridge forming work, ridges are formed on soft or uneven ground
The transmission case and the bracket are tilted and lowered
Does not damage the adjacent shallow seeding grooves ridged in the previous process at the lower end of the transmission case and the bracket , even if the seeding groove is lowered from the predetermined position, and the drainage groove moldings and the seeding groove moldings are not damaged. , Deep drain grooves and shallow seeding grooves are continuously formed.
