Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a tillage device, and more specifically to an improvement in a tillage device that is provided to obtain the cutting and reversing action by forcibly driving a disk curved in an arc shape. .

One of the methods of cultivating soil is to forcibly rotate a disc that is curved into a spherical shape with a gentle arc.
A tillage method in which the soil is cut and turned over by the rotation of the same disc was previously proposed by the applicant of the present invention (Japanese Patent Laid-Open No. 1125833/1983).

However, in the above proposal, each disk is provided with an appropriate angle of elevation so that its concave surface faces the traveling side, so that a significant tilling resistance is generated on each disk, and this resistance causes the tractor's main body to The present invention is an attempt to improve the above-mentioned conventional situation, and the purpose of the invention is to maintain the straightness of the disc, thereby reducing the amount of dirt caused by the disc. The objective is to improve the cutting and reversing effects of the machine.

That is, a feature of the present invention is that the straightness of the tiller is maintained by a stabilizing wheel connected to one end near the rear end of the tiller, which is connected to the rear of the tractor body at an appropriate angle of inclination. The gist of the present invention is to install a rotary shaft horizontally behind the tractor body so that it can be driven strongly, and the rotary shaft has an appropriate inclination angle with respect to the center line in the traveling direction of the tractor body. A number of disks curved in an arc shape are mounted on the rotating shaft at regular intervals, while a conical disk is mounted on one end of the rotating shaft at a rear position of the disk mounted on the same part. The structure is such that a stabilizing ring formed by a pedestal part and a disk part having a larger diameter than the truncated cone part is disposed.

DESCRIPTION OF THE PREFERRED EMBODIMENTS In the following, tongue-like embodiments of the present invention will be explained with reference to the illustrative drawings. In each drawing, (1) is the four-wheeled tractor body, (3) is the PTO shaft that protrudes rearward from the rear of the tractor body (1), and (2) is the tractor body fil.
(4) is a three-point link hitch that is connected to the rear of the vehicle via a hydraulic mechanism (not shown) so that it can be raised and lowered freely.
The frame rod (4) is horizontally suspended between the left and right lower links of 2), and the frame rod (4) has an appropriate inclination angle with respect to the center line in the traveling direction of the tractor body (1), that is, the frame rod (4) It is installed diagonally toward the rear. Same frame rod (4)
A gear box is provided at an intermediate position in correspondence with the PTO shaft (3), and the tip of the PTO shaft (3) is connected to a bevel gear mechanism (FA not shown) built in the gear box (51). It is set up as follows.

A φ encasing (7) containing a chain@structure (not shown) is fixed to one end of the frame rod (4), that is, one end that is located diagonally to the front, and the other end, that is, one end that is located diagonally to the rear, is fixed to the side The plate (8) is attached by Vi.

The chain case (7-inch and side play h) extends downward from the frame rod (4), and the lower end f
! A rotating shaft (9) is horizontally mounted across the AS I river, and a plurality of disks OQ are mounted on the rotating shaft (9) at regular intervals.More specifically, each disk 00 is exactly spherical. It is formed into an arc shape with a gently curved surface as if a part has been cut out, and is mounted on the rotating shaft (9) with its concave surface facing the direction of movement. Between the side plates (8), a mudguard, which will be described later, is located near the upper end, and the plate υ is installed with a rod (b) parallel to the frame rod (4), and the same is installed on the rod 011. The mudguard above is a board @
is detachably installed vertically so as to be able to come into sliding contact with each disk QQ.

On the other hand, at one end of the frame rod (4) diagonally toward mI, an arm Oa is extended diagonally forward and inward from the enclosure (7), and at the tip of the arm Oa is a stabilizing roller 0.
4 are connected in a height-adjustable manner, and at one end of the frame rod (4) diagonally toward the rear, an arm 06 extends diagonally rearward and inward from the side plate (81), and the rear end of the arm 〇〇 A stabilizing wheel (to) is also connected to the part so that the quality can be adjusted freely.That is, the stabilizing wheel (to) is provided so as to be located behind the disk ag which is mounted on one end of the drive shaft (9) diagonally toward the rear. It will be done.

More specifically, the stable I# (g) is formed of a truncated conical part (15a) and a disk part (15b) having a larger diameter than the truncated conical part (15a), and is oriented inward with respect to the arm αQ. and are connected in a forward sloping manner. That is, the truncated conical portion (15a) is placed in contact with the slope of the 49F plate cut by the disk αQ, and the disk portion (15b) is provided so as to cut into the tiller plate.

Next, the operation will be explained.◇ By driving the engine (not shown) mounted on the tractor body, the driving force is transmitted to the traveling mechanism 4, and the traveling action of the tractor body is obtained.

On the other hand, the same driving force is generated by the PTO shaft (3) and the gearbox (5).
The bevel gear mechanism inside, the drive shaft inside the frame lever 4), and the engagement mechanism inside the chain case (7) (all not shown)
is transmitted to the rotating shaft (9) by the diameter of
．． (approximately 5 times). More specifically, as described above, through the rotational action of each disc αQ, a cutting action of soil destruction is obtained, and an action of turning over the soil thus cut is continuously obtained.

On the other hand, the stabilizing wheel OI9 provided at one end of the frame rod (4) on the diagonally rearward side is positioned behind the disk 00 which is mounted on one end of the rotating shaft (9) on the diagonal rearward side. The truncated cone part (15a) is in contact with the slope of the tiller cut by the disc OQ,
In addition, since the disk portion (lOb) is provided so as to bite into the tiller, it is possible to obtain the effect of absorbing the reaction force of the tillage resistance generated in the disk QG, that is, the effect of maintaining the straightness of the tiller.

The present invention is constructed as described above, and in addition to being able to improve the cutting reversal effect against earth damage, it also improves the straightness of the Kasuri-goshi. It has now become possible to maintain the soil and obtain an effective tillage effect.
