Description

DETAILED DESCRIPTION OF THE INVENTION [Technical Field of the Invention] The present invention relates to a pasture reseeding device, for example, one that employs a rotary for normal tillage and performs partial tillage to regenerate grassland.

[Technical background of the invention and its problems]

The vigor of grass deteriorates over time. Therefore, the yield of pasture also tends to gradually decrease. One of the reasons for this is thought to be that grass roots become tense with each other and lose their activation. Therefore,
In such cases, it is possible to completely plow the pasture and sow new grass seeds, but this method requires several months for the grass to grow to the point where it is suitable for harvesting. During this period, there is a disadvantage that there is no harvest, even if it is temporary. Further, in the case of full-scale plowing, there is a disadvantage that soil is washed away in the direction of the slope when the land is sloped, and there is also the problem that a working machine for full-scale plowing requires a large amount of horsepower.

[Purpose of the invention]

The present invention has been made in view of the above-mentioned problems, and makes it possible to partially re-sow grass seeds in a pasture while maintaining a state in which the grass can be harvested.
It aims to revitalize existing grasses that have deteriorated over time, prevent soil erosion on sloped areas, and renew grasslands so that grass can be harvested continuously using relatively low horsepower. The purpose is to

[Summary of the invention]

The pasture reseeding device of the present invention rotatably mounts a tilling shaft on which tilling claws are removably protruded radially at predetermined intervals in the axial direction, and the tilling shaft is moved at a selected position. In place of the tilling claws, straight-edged root cutting claws are removably protruded, and a cover body covering the upper part of the tilling claws except for the root cutting claws is provided on the tilling shaft, and the rear part of this cover body A seeding machine is connected to the tiller to sow seeds in the partially cultivated area using the tilling claws.

It is detachably attached at 12. Further, each flange 10 at a selected position where the tilling claw 11 is not attached, that is, the tilling claw 11 is removed, has a tilling claw 1 attached thereto.
1, straight-edged root cutting claws 13 are removably attached with bolts and nuts 14 facing in opposite directions. Therefore, instead of the tilling claws 11 left on the flange 10 and the tilling claws 11, the flange 1
The root cutting claws 13 attached to 0 are alternately arranged in the axial direction of the tilling shaft 7.

Furthermore, the chain case 5 and bracket 6
A cover body unit 15 is removably attached in place of the full-face cover body that covers the entire upper surface of the rotary tillage work body constructed by attaching tillage claws 11 to each flange 10 between the rotary tillage work body and the rotary tillage work body. This cover body unit 15 has plate-shaped side frames 17 and 1 on both sides which are detachably attached to the inside of the chain case 5 and the inside of the bracket 6 with bolts and nuts 16.
8, and support rods 19 and 20 are horizontally suspended between the front and rear parts of the side frames 17 and 18 on both sides, and the tilling claws 1 are arranged in the axial direction of the front and rear support rods 19 and 20.
A plurality of box-shaped cover bodies 2 with a U-shaped cross section and consisting of an arc-shaped top plate covering the upper part of the cover body 1 and side plates on both sides.
1 is attached so as to be adjustable in position, that is, to be slidable in the axial direction, via mounting fittings 22 and bolts/nuts 23 provided at the front and rear of the cover body 21.
A connecting fitting 25 having an attachment 24 is integrally protruded from the mounting fitting 22 at the rear of the cover body 21, and a screen 27 and a leveling plate 27 are attached to the rear portion of each cover body 21.

Next, a connecting frame 29 of a seeding machine 28 is removably connected to the connecting fittings 25 of each cover body 21 via an attachment 24. In this seeding machine 28, the connecting frame 29 is fixed to the front part of the main body frame 30, and a suppression drive wheel 31 is rotatably mounted on the rear part of the main body frame 30. In addition, the main body frame 30
A hopper 32 containing seeds is provided at the middle upper part of the hopper 32, and an agitator 33 is rotatably built into the feeding portion of the hopper 32.
An interlocking medium 35 is suspended between one end of the shaft 34 and the suppression drive wheel 31. Further, a sowing body 36 for sowing seeds from the dispensing part is vertically disposed below the dispensing part, and the lower part of the dispensing body 36 extends into an opener 37 attached to the main body frame 30.

In addition, in the figure, 38 is a connecting frame protruding from the front part of the machine frame 1.

In this structure, the connecting frame 38 of the machine frame 1 is connected to the connecting portion of the tractor, and the input shaft 2 is interlocked and connected to the output shaft portion of the tractor.

Next, the tractor is driven to tow the machine in the pasture A, and the tilling shaft 7 is driven in conjunction with the input shaft 2, transmission 4, output shaft 8, and chain 9.

As a result, the pasture A corresponding to the part of the tilling shaft 7 having the tilling claws 11 is continuously divided into multiple rows of partial tillage B with a predetermined width by the tilling claws 11 arranged at predetermined intervals. The pasture A, which corresponds to the part of the tillage shaft 7 that has the straight-edged root cutting claws 13, has roots of pasture C that are cut by the root cutting claws 13 arranged at predetermined intervals. A cut is made, and this is a predetermined narrow width and multiple rows of excavation grooves D.
It is done continuously as follows. As a result, grass C is activated. By moving the tractor back and forth in the pasture A, multiple rows of partial plowing B and excavated grooves D are alternately formed at predetermined intervals in the pasture A. At the same time, the suppression drive wheel 31 of the seeding machine 28 connected to the connecting fitting 25 of each cover body 21, which is in contact with the pasture A, rotates, and the agitator 33 of the hopper 32 is rotated in conjunction with the interlocking medium 35. At the same time, the grass seeds E stored in the hopper 32 are continuously sown from the feeding section via the sowing body 36 onto the partially tilled upper surface B, and are crushed by the crushing drive wheel 31.

In the above case, the upper part of each tilling claw 11 partially left on the tilling shaft 7 is covered by a cover body 2 formed by providing side plates on both sides and an arc-shaped top plate between the upper parts.
1, the cultivated soil that is scattered when tilled by the tilling claws 11 is covered by the grass C on the outside.
Instead of scattering and burying the pasture C, it is guided to fall onto the partially tilled B, forming a sowing bed while tilling the grass.

Also, depending on the situation of pasture A, tillage claws 1 will be left.
1, the cover body 21 is slid along the support rods 19 and 20 in accordance with the settings so as to cover the upper part of each tilling claw 11 at the set position. Make it.

In this way, it is possible to maintain the grass C in a state where it can be harvested, sow new seeds between the grasses C, cultivate this grass, wait for growth, and prepare for harvest.

In the embodiment, the connecting fitting 25 of the cover body 21
Although the case where the seeding machine 28 is attached has been described, the present invention is not limited to this, and a fertilizing machine or a fertilizing/seeding machine may be attached.

〔Effect of the invention〕

According to the present invention, it is possible to partially till the meadow so that grass seeds can be re-sown in the meadow using the tilling claws of each row while maintaining the state in which the meadow can be harvested. Seeds for supplementary sowing can be reliably sown in the partially cultivated area of each row, and in addition to this partial plowing and sowing, root cutting claws in each row can reliably sow seeds for established pasture that has changed over time. It is possible to activate the grass by cutting the roots, and since it is partial tillage and not front tillage,
It can prevent soil from being washed away even on sloped land.
In addition, seeding work and pasture activation work can be performed with less horsepower than front tillage, and therefore, grassland can be cultivated so that pasture can be harvested continuously using a rotary for normal tillage work. Can be updated.
