Description

[Detailed description of the invention] Technical field of the invention The invention relates to a ridge bed forming device, for example, which uses a rotary tiller to partially till an additional seeding bed for sowing grass seeds, etc. in rows of a predetermined width in a meadow or the like. Concerning what forms.

Technical background of the invention and its problems In general, grass in pastures grows for about 5 to 50 minutes after sowing.
After 6 years, the grass vigor gradually deteriorates and the yield tends to decrease.

In such cases, the conventional practice is to plow, turn over, crush, and level the entire surface of the pasture including the old pasture, and then sow new pasture seeds. However, with this method, there are times when grass cannot be harvested, albeit temporarily, and requires a great deal of labor due to full cultivation, and if the pasture is on a slope, the cultivated soil may be washed away by rain. There are drawbacks such as:

Therefore, as a way to compensate for the shortcomings of the above methods, the pasture is partially tilled to form a row bed for row sowing.
One possibility is to supplementally sow grass seeds, but with this method, the tilled soil will be scattered in areas other than the row bed for row sowing, and the remaining pasture that will not be reversed will be covered with tilled soil and buried. In addition, there is a problem that row beds for row sowing cannot be formed in an orderly manner.

Purpose of the invention The present invention is to make it possible to form row beds for row sowing in an orderly manner by reliably guiding tilled soil to fall onto the remains of the tilled area without scattering it onto the remaining crops. This is the purpose.

Summary of the invention The invention consists of a machine frame, a rotary work body that is attached to the machine frame so as to be rotatable in the up-cut direction and leaves tilling claws at each ridge formation interval, and a cover body that covers the upper part of the rotary work body. and a guide cover unit which is detachably attached to the lower surface of the cover body at each ridge formation interval and which guides the tilled soil cultivated by the tiller claws onto the tillage mark.

Due to the earth pressure released against the lower end part, it moves forward and backward against the coil spring 19 and is elastically deformed, and its upper part swings and comes into contact with the cover body 12. While the front cover 22 is separated, each eccentric block of the pressing mechanism 24 provided close to the front part of the front cover 22 presses the front cover 22 separately, and each part of the front cover 22 is irregularly pressed. Therefore, in combination with the flexibility of the front cover 22, the cultivated soil on the front cover 22 is prevented from adhering to the front cover 22 and rising up even in the case of highly humid cultivated soil.

In addition, the cultivated soil guided into each guide cover unit 35 is controlled by the side plates 38 on both sides and the auxiliary side plates 44 on both sides connected to the side plates 38, and is thrown backwards so that it does not scatter to the sides. It is reliably guided to fall onto the remains of the tillage area. At the same time, relatively large grass stocks and coarse debris are guided to fall by each control rod 41 of the screen 42, and each control rod 4 is placed above the grass stocks and coarse debris.
The cultivated soil that passed between 1 falls and covers it,
Therefore, a plurality of row beds for row seeding in which organic matter is buried are formed at predetermined intervals. Also in this case,
A rubber plate 39 is provided on the inner surface of the induction cover unit 35.
Since the guide cover unit 35 is stretched, cultivated soil will not adhere to the inner surface of the guide cover unit 35. In addition, each guide cover unit 35 is removed from the cover body 12, and each flange 7 from which the tilling claw 8 has been removed is removed.
By again attaching the tilling claws 8 radially to a, a tilling work machine including a series of rotary work bodies can be constructed.

In addition, when carrying out the work, with the guidance cover unit 35 installed as described above, the machine frame 1
By attaching a fertilizing seeding machine to the top and arranging a fertilizer discharge port and a seed discharge port above the ridge bed for each row sowing, the ridge bed can be formed in one process and this partially formed Fertilization and sowing operations can be performed on each row bed.

Effects of the invention According to the invention, a rotary work body with tilling claws left at each ridge formation interval is attached to the machine frame so as to be rotatable in the up-cutting direction, and a cover body is provided on the top of the rotary work body to prevent this. A guide cover unit is detachably attached to the lower surface of this cover body to guide the cultivated soil cultivated by the tiller claws onto the tillage mark at each ridge bed formation interval. As a result, the tilled soil can be reliably guided to fall onto the tillage area using the width of the guiding cover unit, without scattering and falling on the remaining crops, thereby forming a row bed for row sowing in an orderly manner.
In addition, this guide cover unit is detachably attached to the cover body, so by attaching it to the cover body of the rotary tillage machine as appropriate and leaving the necessary tillage claws, the rotary tillage machine can be used as a ridge bed forming device for row seeding. The rotary tiller can be used for multiple purposes and is therefore suitable as a ridge bed forming device for row sowing grass seeds, for example.
