Description

[Detailed Description of the Invention] Technical Field The present invention relates to a tilling method using a disc, and more specifically, to a method for obtaining a tilling action by forcibly driving a disc formed into a disc shape with a gently curved surface. The present invention relates to a tilling method in a tilling device provided.

Conventional technology plowing In addition to plows and rotaries, disc plows have been commonly used as working machines for a long time.
Since the tip is not sharp, it cannot be plowed deeply in dry, hard soil unless a certain amount of weight is applied. ■If you increase the speed to increase work efficiency, too much dust will fly. ■If the distance between the disks is too narrow or if they are installed in parallel, the soil will get caught between the disks, making it impossible for the disks to rotate. It has the following disadvantages.

As a way to overcome these shortcomings of disc plows, a method of forcibly driving the disc has been proposed (for example, British Patent No. 934,865), but until now there has been no method to effectively reduce the soil resistance against the disc plow. There is no way to treat it, so the reality is that it has not become widely available until today.

However, the cause seems to be the rotation ratio between the drive wheel on the tractor side and the disc. In other words, if the rotation of the disc is too fast relative to the rotation of the drive wheel of the tractor, the rapid rotation of the disc will result in the soil being immediately excavated and the dust being sent in between each disc at a high speed while continuously turning over nine times. In this case, the dust gets stuck between the discs before the tractor moves forward, creating a large resistance to the rotation of the disc. Friction and excavation resistance make the propeller unable to rotate.

Although the above problems can be solved by slowing down the rotation of the disc and increasing the torque, it also reduces the slip rate of the disc against the soil, which slows down the forward movement of the tractor. A problem occurs in which deep plowing is not achieved due to insufficient soil excavation and turning time, resulting in a loss of l''L.

Purpose of the Invention The present invention is an attempt to improve the above-mentioned conventional situation, and the purpose of the present invention is to limit the peripheral speed ratio of the disc sliding against the drive wheel within a certain range. The structure of the invention, that is, the present invention improves a conventional disc plow to forcibly drive the disc 2, and the disc? The circumferential speed ratio of the disk to the drive wheel of the Rakuta Isoko is set within a certain range [Thus, the traction resistance is small and an effective soil inversion effect is obtained. In other words, the disk must be forcibly driven. Gender etc. have a complex influence, but misfire #J
& In this case, by properly determining the rotation ratio between the drive wheels and the disc, the delicate action of the disc digging and turning the soil, and the time during which the tractor continuously moves forward, can be controlled appropriately. While the excavated and plowed dirt is being reversed with the discs, the tractor moves forward, and the dirt that has been raised is reversed diagonally backwards with a slight delay in time. The rotational resistance of the disc will not increase due to the soil foundation competing or pinching, and the tractor will not move forward unless the rotation is slow and the disc does not dig deep into the soil. By making it possible to obtain the ratio with the rotational speed in a simple way, that is, by numerically determining the high speed at the upper limit and the slow speed at the lower limit, and using it within that limited range, the lowest resistance can be obtained. It is characterized by being able to exhibit the best performance, and the gist of the present invention is to set the circumferential speed ratio of the disc to the drive wheel in a range of 2 times to 20 times that of the drive wheel. There is a particular thing.

EXAMPLES Different embodiments of the invention will now be described with reference to the illustrative drawings.

In each drawing, (1) shows the rear wheels of a four-wheeled tractor machine;
Namely, the drive wheel, (3) is a PTO shaft that protrudes rearward from the rear of the tractor body (1), and (2) is the drive wheel that is connected to the rear of the tractor body (1) via a hydraulic mechanism (not shown). The three-point link hitch (4) is a frame rod that spans horizontally between the left and right lower links of the three-point link hit (2). It is installed diagonally from the front to the rear at an appropriate angle of inclination (Gyoung machining allowance is an angle) with respect to the center line. The same frame rod (4) is provided with a gear box (5) at an intermediate position corresponding to the above-mentioned P T O11i1+1 (3).
The tip of 1+1 (3) is provided to connect with a hebbel gear mechanism (not shown) built in the same gear box (5).

A chain case (7) containing a chain machine (not shown) is fixed to one end of the frame rod (4), that is, one end that is diagonally toward the front, and the other end, that is, one end that is toward the rear of 9FI. ε Side play 1- (8) is fixed.

The chain case (7) and side plate (8), which extend downward from the frame rod (4), are equipped with the same hinges! /I
A rotating shaft (9) is horizontally mounted across the M section G.
9), a plurality of grained disks (10) are mounted on a shaft at regular intervals. History [For more details, each disc 00] is formed into an arc with a gently curved surface with just a portion of the ball's pressure cut out, and its concave surface opposite to the rotation axis (9)
It will be placed on the shaft. That is, the disk (10) can be forcibly driven via the drive 2 of the rotating shaft (9), and the disk (10) has a circumferential speed ratio of 2 to 20 times with respect to the drive wheel (1). will be established. Also, between the chain case (7) and the side plate (8), a mudguard plate θ2), which will be described later, is located near the upper end and is attached to the rod 01.
) is installed parallel to the frame rod (4), and the mudguard plate (12) is attached to the rod (1) so that the plate (12) can be attached and removed in sliding contact with each disc (10). It will be installed vertically.

On the other hand, one end 9 of the frame rod (4) near the diagonal front side is connected to the arm 03 toward the diagonally front inward side from the chain case (7).
) is extended, the tip of the arm (13) is connected to a stabilizing roller (height-adjustable), and one end of the frame rod (4) diagonally rearward is connected to a side plate (8).
An arm (16) extends obliquely rearward and inward from ), and a stabilizing shaft (15) is connected to the rear end of the arm (16) so as to be height adjustable. That is, the stabilizing shaft (15) is provided so as to be located behind the disk (10) which is mounted on one end of the drive shaft (9) diagonally toward the rear.

Next, I will explain the details of its creation.

By driving an engine (not shown) mounted on the inside of the tractor, its driving force is transmitted to the traveling mechanism, and the traveling action of the tractor machine 1 is obtained. On the other hand, the driving force is generated by the PTO shaft (3), the bevel gear mechanism in the gear box (5), the drive shaft in the frame rod (4), and the chain case (
7) Inside the chain mechanism (all not shown), the eave axis (9) is rotated in diameter! , : It is possible to obtain an operation in which each disc (10) rotates at a speed slightly higher than the traveling speed of the tractor function, that is, at a peripheral speed that is 2 times to 20 times the peripheral speed of the drive wheel (1). It will be done. In this way, the disc (1, 0) rotates at a speed slightly faster than the taxis speed inside the tractor machine, and the rotation of the disc (1, 0) actively cuts the soil while moving one tractor machine forward. In other words, it is possible to obtain the effect of turning over the soil without applying almost any traction resistance to the traction machine.

Effects of the Invention The present invention is constructed as described above, and as described above, the disc is rotated at a circumferential speed in the range of 2 to 20 times relative to the driving wheel G. By doing so, we were able to significantly reduce the drag [resistance 2], and as a result, we were able to achieve faster tilling work.
