Description

DETAILED DESCRIPTION OF THE INVENTION [Object of the Invention] (Industrial Application Field) The present invention relates to a tillage device for tilling and inverting tilled soil with a relatively large amount of soil.

(Prior Art) Conventionally, as means for plowing and inverting cultivated soil with a large piece of soil, for example, the plow tilling method using a plow body and the desk tilling method using a plurality of desks are known.

In the plowing method, the tilled soil is plowed with a tip metal, and the plowed soil is turned over laterally in the direction of propagation using a plow spatula connected to the plow metal.

In addition, in the above-mentioned desk tilling method, the tilled soil is tilled by a plurality of desks that rotate or drive while tilted at a predetermined angle with respect to the direction of travel, and the tilled soil is distributed to the sides of the desks in the direction of inclination. It is designed to be reversed.

(Problems to be solved by the invention) According to the plow tilling method and desk tilling method mentioned above,
The plowed soil is all turned over to the side in the direction of travel, so the entire plowed soil moves to the side by the width of the plowed soil. At the same time, furrows as large as the width of the tilled soil will be formed at the edges of the field after the last plowed soil is turned over. After the work, there is a problem in that as a correction work, for example, soil moved laterally by the rotary tiller must be returned to the opposite side of the soil reversal direction.

Therefore, the present invention has been made in view of the above points, and involves vertically cutting cultivated soil in advance to a width to be tilled, plowing this cut soil, and converting this tilled soil into It is an object of the present invention to provide a tilling device which prevents tilled soil from moving to the side by inverting it into a trench after tilling.

Further, the second tillage reversal body 14 is made of, for example, a small bottom, and a guide portion 17 having a length shorter than the guide portion 15 of the first tillage reversal body 12 is continuous at the rear of the tip portion 13. The guide portion 17 is formed so as to extend toward the rear portion thereof, and gradually toward the side portion in the traveling direction, that is, the side opposite to the curved direction of the reversing portion 16 of the first plowing reversing body 12. An inverted portion 18 curved toward is continuously formed. Therefore, the first tillage inversion body 1
2 is connected to the support frame 9 in an upwardly inclined state at a predetermined inclination angle, and the second plowing reversible body 14 is connected to the support frame 9 with its tip part 13 connected to the support frame 9. The reversing part 18 is arranged at the rear of the tip part 11 of the raising and reversing body 12, and the reversing part 18 is connected to the reversing part 1 from the middle lower surface part of the guiding part 15 of the first tilling and reversing body 12.
They are connected in a state in which they protrude halfway toward the lower surface part of 6, and in a state in which they are inclined upwardly at a predetermined inclination angle.

As a result, the first and second tillage inversion bodies 12,
14 are arranged in parallel with their inner edges close to each other, and the inverted part 16 of the first tilling inverter 12 is located at the rear upper part of the second tiller inverter 14, and The reversing section 18 of the first tillage reversing body 12
The reversible portions 16 are protruded from the lower surface portion thereof toward the other side in such a manner that they intersect with each other in the upper and lower directions.

Next, lower arms 20 having lower pins 19 at their tips are integrally provided on both sides of the main body frame 1 and protrude forward, and a connecting portion 21 is provided on the upper part of the transmission 3 of the main body frame 1. A top arm 22 provided at the distal end is integrally protruded forward, and this top arm 22
and the lower arms 20 on both sides are connected by stays 23. Further, a grounding ring 24 is supported on the lower arms 20 on both sides so as to be adjustable in height.

Next, the operation of the above configuration will be explained.

The lower links on both sides of the tractor are connected to the lower pins 19 at the ends of both sides of the main body frame 1, and the top links of the tractor are connected to the connecting parts 21 at the ends of the main body frame 1. Further, the input shaft 2 of the transmission 3 is connected to the output shaft portion of the tractor via a power transmission shaft, and the height of the grounding wheel 24 is adjusted to set a predetermined plowing depth.

Next, as the machine is towed by a tractor, the transmission 3 is interlocked by the power transmission shaft connected to the output shaft of the tractor, and the rotary shaft 5 is rotated through the interlocking medium, as shown in Fig. 3. , the tilled soil a has each cutting blade 7 attached to the rotating shaft 5.
As the rotation progresses, two rows are sequentially cut in a vertical manner for each row, and as shown in FIG. 4, three vertical kerf grooves b are formed in parallel. In this case, the rotation of each cutting blade 7 provides the driving force of the machine.

Further, following the above-mentioned vertical cutting, the two rows of cut soil c, d are cut into the first and second tillage inverters 12,
The bottom portions of the cut soil (c, d) are plowed horizontally one after the other to a predetermined depth by the tips 11 and 13 whose positions are shifted from front to back of 14. Two rows of grooves g and h are successively formed adjacent to each other in the lower part of the tilled soil e and f. In this case, the plowed soil (e, f) is plowed by cutting the bottom of the cut soil (c, d), so it is plowed with small cutting resistance.

The tilled soil e tilled by the tip part 11 of the first tillage reversal body 12 is sequentially guided rearward and upward by the guide part 15.
From the middle of the plowing process, the plowing reversing body 14 is conveyed while gradually tilting toward the second plowing reversing body 14 , and is then conveyed by the reversing unit 16 .
The plowed soil f, which has been plowed by the plowing reversing body 14, is inverted and thrown into the groove h.

Further, the tilled soil f tilled by the tip part 13 of the second tillage reversal body 14 is sequentially guided rearward by the guiding part 17, and gradually moves toward the first tillage reversal body 12. It is conveyed while being tilted to

That is, the first and second tillage inverters 12,1
As shown in Fig. 5, each of the two rows of plowed soil (e, f) plowed by No. 4 crosses each other in the groove (g) of the plowing trace of the other adjacent row. , h and are reversed, so that the two rows of plowed soil = e, f do not move to the sides as a whole, and the plowed soil = g, h remain plowed. It is directly inverted into the two rows of grooves d and e formed in .

Next, in the tilling device of the above embodiment, a case has been described in which the first tilling reversing body having a large bottom and the second tilling reversing body having a small bottom are arranged side by side. However, other embodiments of the tilling device include, for example, a first tilling inverter consisting of a large bottom and a second tilling inverter consisting of a desk.
A plowing reversal body may be arranged in parallel with the main body frame 1.

In this case, the first tillage reversal body is preferably formed in the same manner as the first tillage reversal body in the case of the above-mentioned embodiment, and is fixed to the main body frame at substantially the same inclination angle, so the explanation thereof is as follows. Although omitted, the second tillage reversal body consisting of a desk is inclined at a predetermined inclination angle with respect to the first tillage reversal body, and its rear upper part is aligned with the inversion part of the first tillage reversal body. It is rotatably mounted on the support frame via a support shaft while protruding from the lower surface.

As a result, the first tillage reversing body acts on the tilled soil in the same manner as in the embodiment described above, and transfers this tilled soil into the groove of the plowing trace of the second tillage reversing body. The second plowing inverter rotates on its own axis and cuts the tilled soil with the rotating leading edge of its outer periphery, while plowing with the curved surface continuous to the rotating leading edge. This plowed soil is inverted and released into the plowing groove of the first plowing inversion body by the rotating rear curved portion.

Therefore, the two rows of plowed soil do not move to the sides as a whole, but are directly turned over into the two rows of furrows formed in the plowing traces of this plowed soil. It is something that

Further, in each of the above embodiments, the case where the first and second tillage reversals are disposed with front end portions shifted in the front-rear direction has been described, but this is not necessarily the case. The front ends of the tillage inverters in No. 2 are arranged horizontally in line, and the tilled soil for two rows is
may be plowed at the same time.

Further, in the embodiment described above, the case where the tillage reversal body is constituted by the first tillage reversal body and the second tillage reversal body has been described, but the present invention is not limited to this. It has a tip part at the tip part with a width to till two rows of cultivated soil at once, and a guide part is connected to the rear part of this tip part with the same width as the tip part,
A drop opening is cut out on one side of the rear of this guiding part,
A reversing body consisting of a desk or the like that can be reversed is installed in the opposite side of the ditch to transfer one row of plowed soil to the opposite side of the inlet. A reversing body consisting of a desk or the like for reversing one row of plowed soil may be provided in the opposite groove.

〔Effect of the invention〕

According to the present invention, the tilled soil can be reliably turned over into the ditch at the tilled position without moving it to the side. In this case, the tilled soil can be tilled in an orderly manner by cutting it vertically to the width to be tilled in advance, and each tilled soil can be tilled horizontally at the bottom by having both sides cut in advance. Since only cutting is required, plowing can be done smoothly with low cutting resistance.
