Description

DETAILED DESCRIPTION OF THE INVENTION [Object of the Invention] (Industrial Field of Application) The present invention relates to a tilling device, and more particularly, to one that tills soil while suppressing lateral movement of the soil.

(Prior Art) Conventionally, this type of tillage device includes, for example,
As described in Japanese Patent Application Laid-Open No. 60-214801, a plurality of vertical cutting blades that make vertical cuts in the cultivated soil are arranged side by side at predetermined intervals in the left and right direction, and the rear part between the vertical cutting blades is A horizontal cutting blade that cuts the cultivated soil horizontally is installed in the section, and a mold board for turning the soil is installed at the rear end of one side of the horizontal cutting blade, and a mold board is installed on the opposite side of the mold board.
A pushing member that presses the top surface of the soil is fixed, and a mold board that guides the soil in the reversal direction is fixed to this mold board and the rear part of the pushing member, and on the opposite side of this mold board, the soil is moved into the groove. A configuration is known in which a pressing member to be reversed is fixed.

(Problems to be Solved by the Invention) The configuration described in the above-mentioned publication is preferable in that the soil can be turned over on the spot in the groove left after plowing the soil. , the rear part of the mold board and pushing member is used to fix the mold board that guides the soil in the reversal direction and the pressing member that reverses the soil into the groove, so if the soil contains a lot of moisture or the soil quality is In these cases, if the flow of soil is poor, the soil may clog the moldboard and the pressing member, and the work may have to be stopped, Since the reversal is induced by the machine, the reversal resistance is large.Furthermore, since the mold board and the pressing member are provided at the rear of the mold board and the pressing member, the overall length of the device increases in the front-rear direction, and the number of parts increases. , and 〓
There is a problem in that a complex arrangement shape is required to sequentially fluidize the soil in reverse directions.

The present invention was developed in view of the above-mentioned problems, and provides a tillage device that smoothly suppresses and reverses the lateral movement of plowing soil, reduces tillage reversal resistance, and enables orderly plowing and reversal of soil. It is intended to provide.

(Means for Solving the Problems) The tilling device of the present invention comprises a machine frame, a drive claw shaft rotatably mounted on the machine frame, and a predetermined interval in the axial direction of the drive claw shaft. A plurality of vertical cutting claws are protruded from the top and cut the cultivated soil vertically, and a plurality of vertical cutting claws are arranged at the rear of each of the vertical cutting claws and are attached to the machine frame to plow and invert the soil between the vertical cutting claws. It consists of a plurality of plow bodies, and a rotary desk attached to the machine frame at the rear upper part of each plow body, tilted toward the plow body at a predetermined inclination angle, to suppress the lateral movement of the soil by the plow bodies. It is equipped with a plurality of suppressors.

(Function) In the tilling device of the present invention, when the drive claw shaft is rotated while moving forward, the plurality of vertical cutting claws protruding from the drive claw shaft are rotated, and the tilled soil is moved to a predetermined depth. Move forward while cutting vertically. In addition, the soil between each kerf after being vertically cut is sequentially plowed by a plurality of plow bodies installed correspondingly.
As this tilled soil is gradually moved in the reversal direction of the lateral part, the movement of each tilled soil to the lateral part is suppressed by the rotation suppressing action of the suppressor consisting of a rotating disk. During this plowing, the soil is guided toward the trenches left behind after plowing, and therefore, each plowed soil is turned over to the vicinity of each trench without moving much laterally. .

In the above case, each plow body 17 plows up the cultivated soil that has been cut vertically with the width previously plowed by the plurality of vertical cutting claws 15, so that the plowed soil can be plowed up in an orderly manner with relatively little resistance. be done. Furthermore, each plow body 17 is disposed close to the rotation locus of the vertical cutting claws 15, thereby preventing contaminants such as raw straw and grass from becoming entangled with the plow body. Furthermore, tillage reversal = soil is controlled by each rotary disk 2
Due to the rotation suppressing action of 3, the soil is smoothly guided toward the respective grooves while suppressing the flow of the soil.
There is no chance of dirt getting stuck between the two.

〔Effect of the invention〕

According to the present invention, a plurality of suppressors consisting of rotary disks for suppressing the lateral movement of soil are disposed at the rear upper part of a plurality of plow bodies, so that plowing can be achieved by the rotation suppressing action of these suppressors. 〓This tillage is done while preventing the soil from moving significantly in the lateral direction.
It is possible to smoothly and reliably guide and reverse the plowing toward the ditch, and the rotation suppressing action of this suppressor can reliably prevent soil from clogging the suppressor, and the plowing and reversal work can be performed continuously. In addition, the reversal resistance for induced reversal of the plowed soil is small, and since the plow body is provided, the plow body itself can automatically reverse the plowed soil through its own plowing reversal action. Furthermore, since the suppressor is disposed at the rear upper part of the plow body, it is possible to prevent the overall length of the device from increasing in the front-rear direction, and the plow body and suppressor Plowing = The soil can be sufficiently guided and turned over toward the groove, so the structure is simple and the number of parts is small.Therefore, overall, there is less lateral movement of the soil.Plowing = Turns over the soil in an orderly manner. It is possible to provide a tillage device that is easy to perform post-work such as crushing soil leveling work and has excellent workability.
