Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a subsoiler for reviving grassland, and more particularly to a subsoiler for reviving grassland suitable for reviving corner plates of grass.

Grasslands, especially pastures, have been trampled over many years by livestock grazing, and the roots of the grass gradually become hardened, making it difficult for the grass to regenerate smoothly, which in turn reduces the yield of pasture and reduces the number of livestock grazed will be forced to decrease.

In this way, a decrease in the yield of pasture leads to a decrease in the number of livestock and can affect the scale of farming, so it is something that must be avoided at all costs.

Therefore, in pastures, in order to resuscitate grasses, the soil that has become hard due to trampling pressure is expanded and softened to improve water permeability and water retention. Pasture disks must be cut to encourage new root growth.

In order to make the Makisada soil soft, a slit of a certain thickness is formed using a sub-soiler, and a wing or a culvert-forming body, commonly known as a cannonball, is pulled by the knife of the sub-soiler. Subsoiler alone does not actively resuscitate grass.

Therefore, with the purpose of increasing the yield of pasture grass, this invention aims to increase the growth of pasture grass by cutting off the important roots of grass, especially the disc part, along with the grassland expansion and softening work using a subsoiler, and promoting the development of new roots. To this end, a cutting blade is connected to the lower end of the subsoiler knife that extends almost horizontally to the trailing edge, and as the subsoiler moves, this cutting blade cuts the disc to an appropriate depth. This feature is characterized in that it is constructed so that it can be cut at this point.

Hereinafter, details of the present invention will be explained with reference to the accompanying drawings.

First, in the figure, reference numeral 1 indicates a subsoiler connected to a tractor T via a three-point hitch t, and this subsoiler 1
A strut 12 is erected at the front end of the subsoiler frame 11 constituting the subsoiler frame 11, and this strut 12 is reinforced with a rear strut 13 extending from its upper end toward the rear end of the subsoiler frame 11.

A box-shaped knife holder 14 is provided at the rear end of the subsoiler frame 11, and the end of a knife 15 is inserted into this knife holder 14 and fixed at an appropriate position with a lock screw 16.

A chisel 17 is provided on the front side of the lower end of the knife 15 so as to be able to excavate the soil.

A plurality of bolt holes 15a are drilled in the rear edge of the lower end of the knife 15, and brackets 18, which are located on both sides of the bolt holes 15a and can sandwich the knife 15, are connected to the bolt holes 15a. There are bolt holes 18a that can be coaxially arranged in parallel, and the mounting position can be arbitrarily determined by appropriately selecting the bolt holes 15a.

A boss portion 19 having a pivot 19a is formed at the rear end of the bracket 18, and a cutting blade 22 is attached to the pivot 19a.
1 is attached to the front end of the blade plate 20 so that it can rotate in a horizontal plane about a pivot 19a.

The width of this blade plate 20 increases from the front end to the rear end, and a cutting blade 21 is formed on the front edge in the direction of movement. 2
It can be cut in 1.

Next, operations using the subsoiler according to the present invention will be explained.

Prior to subsoiler work in a grassy area, etc., the position of the blade plate 20 to be attached to the knife 15 is selected, and the corner plate is cut according to the depth of the roots.

When subsoiler work is performed in a grassland, the cutting blade 21 of the blade plate 20 cuts the roots R of the grass G at appropriate locations as the work progresses.

New roots can grow from the cut root R and absorb nutrients from the soil.

Of course, the work of the subsoiler forms slits in the soil, and the area around the slits is swollen and softened, improving water absorption and retention.

In addition to the embodiment described above, the blade plate 20 is provided with a vertical blade 22 on the rear edge of the blade plate 20 to form a slit in the vertical direction, as shown in FIGS. 4 and 5. It is also possible to cut the corner boards that are stretched over the edges.

The vertical blades 22 are located on both the upper and lower sides of the blade plate 20, and are located inside of both side edges of the blade plate 20, but as shown in FIGS. 6, 7, and 8. Alternatively, the vertical blades 22 may be located on both sides of the blade plate, or, as shown in FIG. 7, the vertical blades 22 may be formed only on the upper side of the blade plate 20.

As is clear from the above description, the subsoiler of the present invention has a structure in which a blade plate with a cutting edge is attached to the trailing edge at the lower end of the knife. It can be cut to promote grass resuscitation.
