Description

DETAILED DESCRIPTION OF THE INVENTION (Industrial Application Field) Uninventively, regarding the disk graph ve1m, it is possible to prevent the disk from lifting up and to enable it to be plowed.

(Prior Art) As a disc plow device that is used by being towed behind a tractor, a plurality of disc shafts are arranged in pairs on the left and right in the shape of a square in plan view, and the discs are attached to the disc shafts. There are some that are rotatable around the axis.l
There are two types of disks: one is a forced drive type in which the disk is forcibly driven via a disk shaft, and the other is a non-drive type in which it is freely rotatable.

(Problems to be Solved by the Invention) However, this kind of device is so compact that the disk rotates around the axis of a horizontal disk shaft, and the butterfly disk does not cut in easily in hard fields. - That is, there is a problem that the device metal body lifts up.Therefore, in order to prevent this lifting, conventionally, the Kuite was installed on the machine frame on the rear side of the disk axis, or If the tractor gets loose when turning with the throat, the balance between the front and rear of the tractor may be lost, and there are disadvantages such as the need to prepare a separate ``!7''. .

[Friendly means of solving problems]

Inventive line - As a concrete concrete means to solve such conventional problems, a plurality of disks are provided, and a pair of left stones are arranged with the disk shaft in a figure-eight shape when viewed from above, and the disks are In a disc plow device that is rotatable around the axis of the disc shaft, a digging resistor that digs into the soil is installed on the rear side of the disc shaft to prevent the disc from becoming buoyant. It is.

(Function) When plowing a field with the disc Oη, the excavation resistor of the disc shaft penetrates into the soil and excavates.
Even if a force in the lifting direction acts on the disk aη, the digging resistor prevents it from lifting.

(Example) Hereinafter, the non-invention will be described in detail regarding the example shown in F5.

Disc plow device (6) consists of a machine frame (a) and a pair of O discs on the left side. It has a side plate (141) which extends downward from the outer end of each of its prongs, and has a support plate (141) which is shaped like a letter (in plan view when viewed from both sides of the upper part).
The rear panes of each of the prongs of the casing are connected to each other by connecting members 0[0]. Each disc (II) fl transmission-

The transmission case has a built-in transmission mechanism that forcibly drives each disc shaft with the help received from the inputs at the top, and also connects the input shaft a to the tractor ltl via the universal joint shaft Sakaki.
is connected to the PTO shaft (3). [disc 0η
It consists of a pair of left and right disc plows (placed at the rear of the 10-room) and a pair of them on the left and right, each of which has a soil board book (c). are arranged so that the plowed gravel is brought to the center.Each clay board book@ has a support @, and seven support posts c!
2 is inserted into the III' holding fitting @ housed in the connecting member 01 so that the upper T:III can be adjusted freely. The holding fitting @ can be changed in position laterally to the connecting member.

In the above configuration, when cultivating a field, the disk aη of the disk plaque 111 is forcibly cultivated in the direction of the arrow a around the disk axis +III with the help of the PTO shaft (3) of the tractor (1). While the disk drive device (

Therefore, even if a force in the direction of lifting up from the field acts on the disk Oη, this beam will work on the clay plate plaque @ and cause the disk 0
It is possible to prevent η from rising. At the same time, since the Hatsu clay board book @ plows the plowed area (c), it is possible to prevent the plowed area from becoming furrowed.

In this case, the clay plate plaque is shifted forward and backward, so
Even though the soil is brought inward, the soil does not interfere with the soil, preventing unnecessary resistance, and allowing for good plowing.

As long as the Hatsu clay plate plaque @ has a small amount of soil turnover,
It is also possible to provide the mechanism shown in Fig. 4 at the same front and rear positions. That is, in FIG. 4, a rotary tilling section (2) is provided on each of the left and right disc plaques (111), and the portion corresponding to the remaining tillage is tilled in advance. Therefore, in this case,
The plowing function of Nitsu Soil Plate Plaque@ is the rotary plowing part (to)
It is only necessary to plow at a depth l slightly deeper than the plowing depth, and since the amount of soil turnover can be reduced, it is also possible to FRV'r at the same position. The tilling claws of the rotary tilling section (to) face outside the company, and are interlocked and connected to each disk shaft through a bevel gear mechanism (4). In addition, the 10,000-disc shaft tilt is connected to the input shaft through a chain transmission mechanism (2) in the chain case (2).

Digging resistor @i,! ! It is also possible to configure the machine knife Q shown in Fig. 5 with a chisel @ full-equipment ratio subsoiler (to). In this case, if the tilling depth of the rotary tiller is made shallow, and the subsoiler (to) side is deeper than the disk aη side, the uplift prevention effect can be sufficiently maintained. . In this case, the soil is cultivated without inverting the soil plate wh of the tiller of the digging resistor to both the left and right sides. Therefore, disk O
In addition to preventing the lifting of
Plowing trace f: Creates two rows of embankment. In addition, since it is distributed to the left and right, not only the tilled soil collides with the excavation resistor (7) itself, but also the gravel (to) thrown away from the gravel and the disc Oη that are far away from the disk aη. Mona (
It is also possible to combine the excavation resistor of the double soil type shown in FIG. 9 with the rotary tilling section. Of course, in this case, the groove of the digging resistor (to) is made deeper than the rotary tiller SQa.

Digging resistor - may be mineral or other material, such as wood. The excavation resistor is not limited to the middle dog, but it can also be simply installed symmetrically.

(Effect of the invention) According to the invention, the digging resistor, which penetrates into the soil and digs, is placed on the rear side of the disk axis, which prevents the disk from lifting, so it is not as difficult as the conventional method. There is no need for eight, and the important balance between l[%
A1-E plowing can be done while reducing weight.
