Description

DETAILED DESCRIPTION OF THE INVENTION (a) Field of Industrial Application This invention relates to an improvement in a tillage device for invert tilling soil.

(b) Prior art and its problems There are generally two types of methods for inversion tillage of soil using a plow: inside tillage and outside tillage.

However, in the inside-out cultivation method, the known center part is raised, grooves are formed on both sides, and the center part becomes higher overall.

On the other hand, in the case of the everting cultivation method, a groove is created in the center,
It has the drawback that both sides are raised and the central part is lower overall, making it impossible to plow a section of the field flat in either case.

(c) Means for solving the problem This invention is proposed in view of the above-mentioned problem, and it is proposed that the land leveling work after plowing, which was conventionally done in order to obtain a truly flat surface, will be improved. It is an object of the present invention to provide a tillage device that can omit the above.

For this reason, the present invention has taken the following technical measures.

That is, a reversing rotor 8 and a guide body 9 that covers the upper and rear parts of the rotating part of the reversing rotor 8 are provided at the rear and upper part of the mowing body 7 that scoops out the cultivated soil in a band shape, and the cultivated soil scooped out by the above-mentioned housing body 7 is disposed. The tilling device has a structure in which the tilled soil is cut into pieces of appropriate length by a reversing rotor 8, and the cultivated soil is turned over while being guided and held by a guide body 9.

(d) Examples and their effects Hereinafter, the present invention will be described in detail based on the drawings.

First, to explain the structure, a tilling device 4 is connected to the rear part of a tractor 1 via a top link 2 and lower links 3, 3 so as to be movable up and down.

A pair of left and right frames 5 provided along the front and back direction,
Vertical rods 6, 6 are provided hanging down in the middle part of 5, and these vertical rods 6
, 6, the plate surfaces of the 6 housing bodies 7, 7 to which the housing bodies 7, 7 are fixed are inclined so that the rear side becomes higher when viewed from the side, and a twisted curved surface is formed on the lateral side. No, target 7a, 7
When the tractor 1 is driven with the tractor 1 set at an arbitrary depth position, the surface portion of the soil is scooped out to an appropriate depth, formed into a belt, and transported rearward. The tilling device 4 includes the above-mentioned housings 7, 7, a reversing rotor 8 connected to the rear and upper part of the housing 7, a guide body 9° frame 5.5 that covers the upper and rear parts of the rotating part of the reversing rotor 8. Coulters 10, 10 vertically installed in the front part so as to be vertically adjustable
．． It consists of 10 mag.

In addition, the reversing rotor 8 has a rotary drum 13 mounted on the left and right chain cases 11 and side plates 12, which are provided hanging at the rear of the frame 45.5.The outer peripheral surface of the one-rotation drum 13 has helical blades for one pitch. 14 is wound around the guide member 9 to shred the soil, and at the same time, it is reversed to guide and hold the soil through cooperation with the guide body 9. Then, by making the circumferential speed of the rotating drum 13 that rotates in reverse slightly faster than the traveling speed, the soil scooped out by the containers 7, 7 slides straight up the plate surface and is rotated by the rotating drum 13. It is rolled up from above and held in an inverted position, during which time it is divided into predetermined lengths by the spiral blades 14.

From the lower end of the guide body 9, the soil is turned over and discharged again into the groove formed by tilling.

Note that reference numeral 15 in the figure is an input shaft that projects forward from the gear box 16 of the tilling device 4, and rotary power is transmitted from the PTO shaft of the tractor 1 via a universal joint.

1 is a mast erected upward at the front of the frames 5, 5, and 18 is an auxiliary frame that connects the upper part of the mast 17 and the upper part of the gear box 16.

Further, reference numeral 19 denotes a stopper member fixed along the lateral side of the guide body 9 to prevent the cultivated soil from being transferred in the lateral direction by the thrust force of the spiral blade 14 while the spiral blade 14 is rotating. It works as expected.

In this embodiment, the frames 5, 5 support two housing bodies 7°7, and one reversing rotor 8 is provided at the rear and upper part of these bodies. It is also possible to use a structure in which the soil is formed into a curved shape so that the soil is scooped out and turned over by the rotor 8.

While moving the tractor 1 forward on the upper side, the tilling device 4
When the rotary part is driven to perform soil tillage work, the cultivated soil scooped out to an appropriate depth through the tip 7a of the container 7 is cut simultaneously by the left and right coulters 10 and 10, and the soil is cut into grass. 7 and is pulled in by the rotating drum 13 of the reversing rotor 8, which is rotating in the reverse direction.

The soil divided into predetermined lengths is turned over while the outer peripheral part is held by a guide body 9, and the cut tilled soil is backfilled into the groove part which has just been plowed by the housing body 7. During this time, there is no horizontal movement of the cultivated soil, which eliminates the problem of the cultivated land in one section of the field becoming medium-high or low in the center, making it impossible to obtain a flat surface.

In particular, in this embodiment, since the reversing rotor 8 is constituted by the rotary drum 13 and the spiral blades 14, the soil can be divided and reversed accurately, and the soil can also be discharged well.

(E) Effects of the Invention Since the present invention is configured as described above, it has the following technical effects. That is, the cultivated soil scooped out by the grass body 7 slides up the plate surface and is smoothly passed to the following reversing rotor 8, and while it is being rotated while being held by the guide body 9, the soil is Since it is divided and turned over, and is forcibly released from the lower end of the guide body 9, this cultivated soil is separated from the tip 7.
The area that was gouged out by step a will be backfilled. Therefore, the tilled soil is sent laterally one after another, creating grooves on the outside of the field and creating mountains in the center, or conversely, causing problems such as the center becoming lower, and the entire field can be plowed flat. It is possible.
