JPH0591211U - Claw wheel for grooving in seeding device - Google Patents

Abstract

(57) [Summary] [Object] The present invention is a seeding device capable of sowing a groove while cutting it on the surface of a field by means of a ratchet wheel that rotates in the direction opposite to that of the drive wheel. The present invention relates to a grooving ratchet wheel in a seeding device capable of sufficiently covering the seeds with soil. According to the present invention, a soil guide cover is arranged above a grooved claw wheel that rotates in a direction opposite to a drive wheel, and the claws of the claw wheel formed in a rectangular shape are moved as much as possible in the traveling direction of the machine body. It is characterized by being arranged at right angles.

Description

[Detailed description of the device]

[0001]

[Industrial applications]

 In this invention, a grooved claw wheel that rotates in the opposite direction to the drive wheel is provided on the machine body that is supported by the drive wheels so that the soil guide cover is arranged above the claw wheel and the groove cutting is performed. The present invention relates to an improvement of a grooving ratchet in a seeding device in which a seed dropping cylinder is opened in the rear of the ratchet.

[0002]

[Prior Art]

 As a seeding device of this type, there is a direct seeding device (hereinafter referred to as a conventional device) described in Japanese Utility Model Publication No. 50-37287, which is filed by the present applicant.

FIG. 5 is a side view of the main part of the above-mentioned conventional device, and the ratchet wheel 4 is interlocked with the drive wheel 2 so as to rotate in the direction opposite to the drive wheel 2. The claws 5 of the claw wheel 4 are radially implanted in the bearing 6 and fixed to the axle 7 in the traveling direction of the machine body 1. A soil guide cover 8 is provided above the ratchet wheel 4, and a seed dropping cylinder 11 is provided behind it. FIG. 6 is the above-mentioned front view, and the claws 5 of the ratchet wheel 4 are bent so that their tips are directed inward with respect to each other, and are fixed to the axle 7 via bearings 6.

[0004]

[Problems to be solved by the device]

 As is apparent from the above, the claws 5 of the claw wheel 4 in the conventional device are curved inwardly toward each other, and are radial with respect to the axle 7 via the bearing 6 so as to be parallel to the traveling direction of the machine body 1. Since it is fixed to the ground, it is easy to rotate the ratchet wheel 4 to dig a groove with a u-shaped cross section against the surface of the earth, but scoop up a large amount of the excavated soil and flip it up toward the soil guide cover 8 above. Due to the lack of ability, there was a drawback that the seeding groove behind the ratchet wheel 4 could not be sufficiently covered with soil.

[0005]

[Means for Solving the Problems] The present invention aims to eliminate the drawbacks of the above-mentioned conventional devices, and forms a sowing groove of an appropriate depth on the ground surface according to the progress of the airframe, and at the same time Scoop a large amount of soil, hit it against the upper soil guide cover, and in response to the soil released to the rear of the ratchet wheel, the seed cutting put into the sowing groove behind the ratchet wheel can be completely covered with soil. It provides a nail wheel for use.

That is, this invention has a soil guiding cover arranged above the grooved ratchet that rotates in the direction opposite to the drive wheel, and a seed drop cylinder is opened behind the grooved ratchet. In the above, the gist of the ratchet wheel in the seeding device is characterized in that the claws of the ratchet wheel are formed in a rectangular shape and the claws are arranged at right angles to the traveling direction of the machine body. To do.

[0007]

[Action]

 Since the claws of the ratchet according to the present invention are arranged almost at right angles to the traveling direction of the machine body, a large amount of the soil dug up on the surface of the ground is scooped, hit against the soil guide cover above the ratchet, and the reaction is generated. A large amount of soil was released to the rear of the ratchet.

[0008]

【Example】

 FIG. 1 shows an embodiment of the present invention, and FIG. 1 is a side view of a seeding device according to the present invention, in which a machine body 1 is supported by a drive wheel 2 so that it can travel freely, and a handle 3 is provided at a rear portion thereof. There is. 2 is a side view of the main part, FIG. 3 is a front view, and FIG. 4 is a perspective view of the ratchet wheel. In these drawings, the ratchet wheel 4 has a rectangular tabular claw 5 fixed radially to the axle 7 via a bearing 6 so as to be supported at right angles to the traveling direction of the machine body 1. There is. The ratchet 4 is rotatable in the direction opposite to the drive wheel 2, and if the ratchet 4 is provided so as to be adjustable up and down, a seeding groove having an arbitrary depth is formed on the ground surface, which is convenient. On the other hand, a soil guide cover 8 is provided above the ratchet wheel 4 to guide the soil from which the nail 5 has flipped up to the rear of the ratchet wheel 4. The guide cover 8 is preferably made of an elastic member having high flexibility.

A seed tank 9 is provided with a seed dropping cylinder 11 that hangs down at the bottom via a seed feeding device 10. The tip of the dropping cylinder 11 is open to the rear of the ratchet wheel 4. Further, the seed feeding device 10 is interlocked with a grounding wheel 12 provided at the tip of the body 1 and is configured to feed the seeds in the seed tank 9 sequentially in response to the traveling of the body 1.

Since the embodiment of the present application is configured as described above, when the drive wheel 2 is driven to drive the machine body 1 and the ratchet wheel 4 is rotated in the opposite direction to the drive wheel 2, a seeding groove is formed on the ground surface. Be touched. Next, when the seed feeding device 10 is brought into a movable state, the seeds in the seed tank 9 are fed out according to the traveling of the machine 1, and are thrown into the seeding groove behind the ratchet wheel 4 from the tip of the seed dropping cylinder 11. However, since the claw 5 according to the present invention is a rectangular flat plate and is arranged almost at right angles to the traveling direction of the machine body 1, a large amount of the soil dug up on the ground is scooped by the claw 5, and the soil guide cover is provided. It is discharged to the rear of the ratchet wheel 4 via 8.

[0011]

[Effect of the device]

 As described above, according to the present invention, a sowing groove is formed on the ground surface as the aircraft progresses, and at the same time, a large amount of soil is discharged to the rear of the ratchet wheel through the soil guide cover. The seeds put into the sowing dip have been effectively covered with soil.
