Description

DETAILED DESCRIPTION OF THE INVENTION [Object of the Invention] (Industrial Field of Application) 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 in the direction of inclination of the desks. 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. Later, 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 was made in view of these points.
It is an object of the present invention to provide a tillage device that can prevent the tilled soil from moving to the side by inverting it into the furrow after tilling.

[Structure of the invention]

(Means for Solving the Problems) The tillage device of the present invention has a main body frame that plows tilled soil in two rows, and has a cutter in the center that divides the tilled soil into each row. A first reversing body and a first reversing body are attached to the dividing body, and each of the divided rows of plowed soil is replaced and inverted in the groove of the other row at the rear of the tilling dividing body. Two inverters are provided facing each other.

(Function) According to the tilling device of the present invention, when the main body frame is towed and moved forward, the tilling dividing body simultaneously tills two rows of tilled soil and sequentially divides the tilled soil into each row. Then, one row of tilled soil of the two rows of tilled soil is transferred into the groove of the other row of tilled soil by the first inverter, and the other row of tilled soil is One row of plowed soil is guided into the grooves of the one row of plowed soil by the second inverter and turned over.

(Example) Next, the configuration of an example of the present invention will be described based on the drawings.

In the figure, reference numeral 1 denotes a main body frame, and the main body frame 1 has lower pins 2, 2 protruding from both ends thereof to be removably connected to the lower link of the tractor, and a top of the tractor at the middle of the upper part of the main body frame 1. A connecting piece 3 that is detachably connected to the link is provided in a protruding manner.

Further, 4 is a tillage division body, and this tillage division body 4 is
It is formed to extend in the front-rear direction with a width for cultivating two rows of cultivated soil, and a tip portion 5, 5 having a substantially triangular shape in plan view for tilling the cultivated soil is formed at the tip end. A guide part 6 is formed at the rear of the guide part 5 to continuously extend rearward, and a discharge recess 7 as a discharge part for discharging one row of plowed soil is provided on one rear side of the guide part 6. An extension guide piece 8 is formed by cutting out the guide part 6 and extends rearward at the other rear side of the guide part 6 for guiding one row of tilled soil. A cutter 9 for dividing two rows of plowed soil is integrally installed at approximately the middle part in the width direction at the front upper part between the cutter 8 and the cutter 9. and,
This tillage division body 4 is fixed to the main body frame 1 in a rearwardly upwardly inclined state at a predetermined inclination angle.

Further, 10 is a first inverting body, and this first inverting body 10 includes, for example, a disk 11 formed in a disk shape.
This desk 11 consists of the main body frame 1
A predetermined slope is provided at the rear end of the connecting frame 12 extending rearward from one side, with the inverted surface 13 facing the inner lower part from the outer side facing the discharge recess 7 of the tilling division body 4. It is rotatably mounted via a support shaft 14 in an inclined state.

Further, 15 is a second inverting body, and this second inverting body 15 includes, for example, a disk 16 formed in a disk shape.
The desk 16 includes a support frame 1 extending rearward from the other side of the main body frame 1.
At the rear end of 7, an extending guide piece 8 of the tilling division body 4 is provided.
It is rotatably supported via a support shaft 19 with its inverted surface 18 facing the rear end and inclined at a predetermined inclination angle toward the first inverted body 10 .

As a result, the connecting frame 1 is connected to the main frame 1.
2 and the first shaft supported by the support frame 17
The second reversing bodies 10 and 15 are located in front and rear of each other so that each of the plowed soil can be exchanged and inverted into the groove of the other row, and the respective inverting surfaces 1
3 and 18 are provided facing each other at the rear of the tilling division body 4 so as to cross each other.

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 2, 2 on both ends of the main body frame 1, and
The top link of the tractor is connected to the connecting piece 3 of the main body frame 1.

Next, when the machine is towed by a tractor in the field, the tilled soil a is successively tilled in two rows of a predetermined width by the tips 5, 5 of the tillage division body 4. Two rows of tilled soil = b is the guiding part 6
, and two rows of grooves c and d are successively formed adjacent to each other in the lower part of the two rows of plowed soil b.

Then, the two rows of plowed soil b, which are successively guided backward and upward by the guide section 6, are sequentially divided into two for each row by a cutter 9 installed midway through the guide section 6. , one row of plowed soil 〓e is dropped from the discharge recess 7 and transferred to the first inversion body 1
0, the first reversing body 10 rotates and its reversing surface 13 inverts it into one of the grooves c, and one row of the other plowed soil f is transferred to the extension guiding piece 8. As well as being guided further backwards by
It is guided from this extension guide piece 8 to the second reversing body 15, and as the second reversing body 15 rotates, it is reversed into the other groove d by its reversing surface 18.

That is, the tilled soil for two rows b cultivated by the tillage dividing body 4 is divided into two by the cutter 9 for each row, and each divided tilled soil b is divided into two by the cutter 9. , f are replaced and reversed in the grooves c and d of the plowing traces of the other adjacent row so as to intersect with each other, as shown in FIGS. 2 and 3. The tilled soil for the rows (e, f) is generally cultivated without moving to the sides.
Two rows of grooves c, d formed on the plowing traces e, f
It is turned over and released inside.

〔Effect of the invention〕

According to the present invention, the tilled soil can be reliably turned over to the tilled position without moving to the side. Furthermore, by plowing two rows, there will be no uncultivated areas in the two rows of furrows. Further, by providing a cutter in the center of the tillage dividing body, two rows of tilled soil can be automatically divided into each row.
