Abstract

PURPOSE:To prevent the thick adhesion of soil to the inner surface of a soil- guiding cover placed above a furrow-opening tine wheel by forming the soil- guiding cover with an elastic material having high flexibility. CONSTITUTION:A soil-guiding cover 7 placed above a furrow-opening tine wheel 4 rotating opposite to the rotation of a driving wheel is formed with an elastic material having high flexibility. The thick adhesion of soil splashed with the tine wheel on the inner surface of the cover can be prevented to prevent the hindrance of the rotation of the tine wheel.

Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a soil guide cover above a grooving claw wheel of an agricultural work machine capable of sowing or transplanting a groove while digging the groove on the surface of a field.

[0002]

2. Description of the Related Art As this type, a soil guide cover for a claw wheel for grooving in a seeding device of Japanese Utility Model Publication No. 52-19858, which is filed by the present applicant (hereinafter referred to as "prior art").
It has been known.

To explain this prior art with reference to FIG. 4, a soil guide cover 7 made of an iron plate provided above the ratchet 4 is swingably supported on a spindle 11 which is horizontally supported on the machine body. Has been done. That is, the soil guide cover 7 is swingably supported with respect to the support shaft 11 through the sliding support hole 13 of the gate type support fitting 12 provided at the top,
The guide retaining rod 14 provided on the support shaft 11 is slidably and loosely fitted into the retaining hole 16 of the retaining metal fitting 15 provided on the front portion of the soil guide cover 7, and the spring supporting rod 17 is The soil guide cover 7 is biased upward and supported via a spring 18.

[0004]

As described above, in the conventional device, the soil guide cover 7 is swingably supported on the support shaft 11, which has a drawback that the structure is complicated and the cost is high. In addition, the result of the practical test is that, regardless of the rocking of the soil guide cover 7, the soil from which the ratchet wheel 4 is flipped up adheres thickly to the inner surface of the cover 7, which impedes the rotation of the ratchet wheel 4 and finally becomes unrotatable. There was a flaw. It is presumed that this is because the cover 7 in the conventional device is made of an iron plate, so that even if the soil flipped up by the ratchet wheel 4 hits the cover 7, the impact is absorbed by the cover 7 and the attached soil does not separate from the cover 7.

[0005]

This invention is intended to eliminate the above-mentioned drawbacks of the prior art, and simplifies the construction to reduce the cost, and the agricultural work in which soil does not easily adhere to the inner surface of the cover. A soil guide cover for a machine is provided. That is, this invention is an agricultural working machine provided with a grooved ratchet wheel that rotates in the opposite direction to the drive wheel, and the soil guide cover provided above the grooved ratchet wheel is formed by a flexible elastic member. The gist is the structure of the soil guide cover in the agricultural working machine characterized by the above.

[0006]

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS The invention of the present application will be described with reference to FIG.
In FIG. 1, reference numeral 1 denotes a machine body, which is movably supported by drive wheels 2 and has a handle 3 at a rear portion thereof. The ratchet wheel 4 provided on the lower front portion of the machine body 1 is interlocked with the drive wheel 2 via an appropriate interlocking mechanism so as to rotate in the opposite direction to the drive wheel 2. Reference numeral 5 is a support fitting, and a guide cover 7 made of an elastic member is suspended and supported above the ratchet 4 via a leaf spring 6 so as to be swingable. The guide cover 7 is a gutter-shaped cover formed of an elastic member having a high flexibility, for suppressing the scattering of the soil splashed by the ratchet wheel 4 and guiding the soil behind the ratchet wheel 4 to drop it. , Curved in a semicircular shape. The relationship between the drive wheel 2, the ratchet wheel 4 that rotates in the reverse direction with respect to the drive wheel 2, and the soil guide cover 7 stretched above the ratchet wheel 4 will be described below. When the vehicle runs, the ratchet wheel 4 rotates in the reverse direction, and a groove for seeding or transplanting is dug on the ground surface. At that time, the soil repelled by the ratchet 4 hits the inner surface of the cover 7 and the cover 7
While being shocked and vibrated, the particles are scattered backward and the claw wheel 4 appropriately covers the groove formed on the ground surface. That is,
In the present invention, the soil guide cover 7 is formed of an elastic member having high flexibility, and is locked by the leaf spring 6 having high elasticity. It vibrates greatly without interruption. Therefore, the soil hitting the inner surface of the cover 7 is hardly peeled off by the vibration of the cover 7 and adhered to the inner surface of the cover 7, so that the ratchet wheel 4 smoothly rotates. It is presumed that this is because the soil guide cover 7 according to the present invention is made of an elastic member having high flexibility and has an essentially strong elastic force.

In the illustrated embodiment, 8 is a seed tank, and a seed feeding device 9 is provided at the bottom. The feeding device 9 intermittently feeds the seeds in the seed tank 8 in a fixed amount in conjunction with the rotation of the drive wheels 2, and a seed guide pipe 10 is communicably connected to the bottom portion. Seed guide tube 10
Has its tip opened close to the ground surface behind the ratchet wheel 4. Then, when the drive wheel 2 is driven to advance the machine body 1, the ratchet wheel 4 rotates in the opposite direction of the drive wheel 2 to dig up a seeding groove of a certain depth on the ground surface, and to raise the body 1 above the seeding groove. Seeds fed from the seed tank 8 of the guide tube 1
It will flow through 0 and be seeded. On the other hand, the ratchet 4
The soil bounced up by is hit on the inner surface of the cover 7 and then discharged to the upper surface of the seeding groove behind the ratchet wheel 4, and the seed seeded in the groove is covered with soil. As described above, the agricultural working machine according to the present invention can form the seeding groove only by traveling in the field, and can appropriately cover the seed placed in the groove with soil. Although the above example is related to a seeding machine, while digging a groove on the ground surface, even in a transplanting machine configured to transplant a plant seedling into the groove, the same effect as the above example It is self-evident to play.

[0008]

As described above, according to the soil guide cover of the present invention, the soil from which the ratchet wheel is flipped up does not thickly adhere to the inner surface of the cover and does not hinder the rotation of the ratchet wheel. Has an effect that farming work such as transplanting can be easily continued. There is also an effect that can be reduced.
