Description

[Detailed Description of the Invention] Industrial Application Field The present invention is a tillage device using disks, more specifically, a plurality of disks formed into a spherical shape with a gently curved surface and having an appropriate gearing angle. By installing the disc and forcibly rotating the disc,
The present invention relates to a mechanism for treating an uncultivated portion of land that occurs at one end of the tillage device diagonally toward the rear of the tillage device installed to cut and turn soil, that is, a ridge treatment mechanism.

BACKGROUND TECHNOLOGY In general, in a tillage device using a disk, the rotating shaft has an appropriate angle of inclination with respect to the central axis along the traveling direction, that is, an appropriate gear angle is set so that the rotation axis extends from diagonally forward to diagonally rearward. A plurality of spherical disks are provided at a corner and have a gently curved surface on the rotation axis, and the disks are rotated at regular intervals with their concave surfaces facing diagonally forward toward one end of the rotation axis. mounted on. By forcibly rotating each disk through the rotating shaft, the outer circumferential edge of the disk cuts the soil, and the concave surface of the disk serves to turn over the cut soil.

Problems to be solved by the invention However, in the case of the above-mentioned tillage device, each disk is attached with its concave surface facing one end diagonally forward of the rotation axis, and the soil cut by each disk is By being provided so that it is reversed toward one end of the rotating shaft diagonally toward the front,
At one end of the rotating shaft diagonally toward the rear, the soil that has not been cut by the disk will remain as uncultivated land.

The present invention is an attempt to improve the above-mentioned problems in order to solve them.The purpose of the present invention is to make it possible to perform tillage without leaving any residual tillage at one end of the rotating shaft diagonally toward the rear. There is a particular thing.

The specific means and actions for achieving the above purpose are as follows.

Means for Solving the Problem The disk is positioned in front of the disk which is mounted on one end of the rotating shaft provided at an appropriate gearing angle, and the disk is slid with its concave surface facing inward. Installed in a rotatable manner.

That is, the disk is rotatably adjustable in the left-right direction (both width directions of the aircraft body), and its rear end is provided inside the front end of the disk, which is pivoted at one end of the rotating shaft diagonally toward the rear. .

Function The soil at the edge of the ridge is cut and turned inward through the rolling action of the disk, and the soil that has been cut and turned inward in this way is further cut and turned over by the succeeding disk. . That is, it is possible to obtain the effect of tilling the soil by the disk without leaving the soil at the edge of the ridge as uncultivated land.

Next, specific embodiments of the present invention will be described with reference to illustrative drawings.

Embodiment 1 is a four-wheeled tractor body, 2 is a three-point link hitch that is connected to the rear of the tractor body via a hydraulic mechanism (not shown) so that it can be raised and lowered, and 4 is a horizontal link between the left and right lower links of the three-point link hit 2. Frame rod 4 is the frame rod for hanging the tractor body 1.
It is installed diagonally so as to extend from diagonally forward to diagonally rearward at an appropriate Giyoung angle with respect to the center line in the direction of travel.

Although not shown, the frame rod 4 is formed in the shape of a hollow pipe, and a drive shaft is housed in the hollow portion. Furthermore, a frame rod 4 is provided at an intermediate position to protrude rearward from the tractor body 1.
A gear box 5 is provided in correspondence with the PTO shaft, and the PTO shaft is provided so as to be connected to a Pepel gear mechanism built in the gear box 5.

At one end of the frame rod 4, that is, at one end diagonally toward the front, a chain case 3 has a built-in chain mechanism.
is fixed, and a side plate 8 is fixed to the other end, that is, one end diagonally toward the rear. Also, a chain case 3 extending downward from the frame rod 4
A rotary shaft 9 is horizontally mounted between the lower ends of the side plate 8 and the side plate 8, and a plurality of disks 10 are mounted on the rotary shaft 9 at regular intervals. More specifically, each disk 10 is formed into an arc shape with a gently curved surface, as if a part of a sphere is cut out, and the concave surface faces in the direction of movement with respect to the rotating shaft 9. The shaft is mounted toward one end of the rotating shaft 9 diagonally toward the front.

Further, at one end of the frame rod 4 diagonally toward the rear, a disk 14 for ridge treatment is mounted in front of the disk 10 so as to be freely rotatable. More specifically, a bracket 12 is provided extending from the connecting rod 11a that connects the three-point link hitch 2 and the frame rod 4 toward one end of the frame rod 4 near the diagonal rear side, and the bracket 12 has a connecting rod installed vertically at its tip. A connecting arm 13 is fitted through the post 12' so as to be vertically and rotatably adjustable, and a disc 14 formed into a spherical shape with a gently curved surface is provided at the lower end of the arm 13, and the concave surface is turned inside. It is mounted on a shaft for free rotation.

More specifically, the disk 14 is rotatably adjustable in the left and right directions (in both width directions of the tractor body 1), and its rear end is mounted on one end of the rotating shaft 9 diagonally toward the rear, as shown in FIG. The disk 10 is provided so as to be located inside the front end of the disk 10.

On the other hand, an arm 16 is provided at one end of the frame rod 4 diagonally rearward and extends diagonally rearward and inward from the side plate 8, and the rear end of the arm 16 is bent into a substantially F-shape. A shaft 15 is fixed to be rotatably adjustable by tightening bolts and nuts, and a stabilizing ring 22 is rotatably mounted on the tip of the support shaft 15.

From the support shaft 15 that supports the stable wheel 22,
A bracket 24 is provided to protrude in the radial direction of the stabilizing wheel 22, and a mud scraping plate 23 is attached to the tip of the bracket 24.

Next, its effect will be explained.

By driving an engine (not shown) mounted on the tractor body 1, the driving force is transmitted to the traveling mechanism and the traveling action of the tractor body 1 is obtained.The driving force is also transmitted from the PTO shaft to the gear box 5. The information is transmitted to the rotary shaft 9 via a bevel gear mechanism, a drive shaft in the frame rod 4, and a chain mechanism in the chain case 3, and each disc 10 is connected to the tractor body 1.
A state in which the disk 14 rotates at a speed slightly faster than the traveling speed of the tractor body 1 (approximately 3.5 times the vehicle speed) and a state in which the disk 14 rotates at the same speed as the traveling speed of the tractor body 1 can be obtained.

As each disk 10 rotates at a speed slightly faster than the traveling speed, the soil is cut by its peripheral edge, and the thus cut soil is transferred to the frame rod 4 through its concave surface. On the other hand, by rotating the disk 14 at the same speed as the traveling speed, the soil at one end of the frame rod 4 is cut diagonally to the rear, and An effect of inverting it inward can be obtained. However,
Since the disk 14 is installed in front of the disk 10, the soil that has been cut and turned inward by the disk 14 can be further cut and turned over by the subsequent disk 10. It will be done. That is, the soil at one end of the frame rod 4 on the diagonally rear side is not left uncultivated, and the disk 10 can till the soil.

Effects of the invention The invention is constructed as described above.
As mentioned above, among the plurality of disks arranged diagonally from the front to the rear with an appropriate gearing angle, one disk is located in front of the disk provided at one end of the disk diagonally toward the rear. By providing two discs and using the discs to cut inward and turn it over,
It has become possible to reliably till the same soil using subsequent disks, and as a result, it has become possible to reliably till the soil without leaving the soil at the edge of the ridge as uncultivated land.
