Description

TECHNICAL FIELD The present invention relates to a tillage cover.

In the conventional technology and the problem to be solved by the invention, in the form in which the auxiliary tilling device is mounted outside the tilling shaft of the main tilling device, the tilling cover of the auxiliary tilling device is fixed. In the cultivating device, the position of the cultivating cover is adjusted depending on the cultivating condition and the like. Generally, when the plowing depth is deep, the flat plate at the rear side of the tillage cover is raised, and the flat plate at the time of scraping work is adjusted so that the tilling device is floated so that it can be lowered for work. In this case, the cultivating cover is moved back and forth around the cultivating axis in order to maintain a constant ground contact angle of the flat plate. In such a form, if the tilling cover of the auxiliary tilling device on the outer side is fixed, a vertical step is generated on the soil surface.

Means for Solving the Problems This invention proposes that the upper part of the main tiller (4) bearing the left and right ends of the tiller shaft (2) on which the tiller claw (1) is arranged against the machine body (3). Main tillage cover (5), which is made rotatable around the tiller axis (2) and covers it
And an auxiliary tilling cover (8) covering the upper part of the auxiliary tilling device (7) mounted on the outside of the bearing portion (6) of the tiller shaft (2) and connected so as to rotate integrally. The structure of the tillage cover will be used.

Effect of the Invention The main tiller (4) is tilled by the tilling claw (1) by the transmission rotation of the tiller shaft (2), and the bearing portion of the tiller shaft (2) is also provided.
(6) The outside auxiliary tilling device (7) is simultaneously cultivated. The main cultivating cover (5) of each of these main cultivating devices (4) and the auxiliary cultivating cover (8) of the auxiliary cultivating device (7) prevent the scattering of the cultivated soil and level the cultivated soil surface. The positions of the main tillage cover (5) and the auxiliary tillage cover (8) differ depending on the working conditions such as the working depth and the scraping work, but when the leveling pressure is increased or the working depth is shallow, these tilling covers are used. Cover (5) (8)
When the leveling pressure is lowered or the plowing depth is increased, the plowing covers (5) and (8) are swung forward or adjusted or controlled.

Effect of the invention Main tillage cover at the time of tilling action by such a tiller
When (5) is rotated around the tilling shaft (2) to the front side or the rear side, an auxiliary tilling device outside the bearing portion (6) at one end of this tilling shaft (2)
The auxiliary tillage cover (8) that covers (7) is also rotated integrally. For this reason, the rotation adjustment, or control, of these both tilling covers (5) (8) is performed easily and easily, and the leveling of the tilling soil by the auxiliary tilling device (7) is performed evenly in the main tilling device (4). It can be molded almost flush with the flat surface.

This auxiliary tillage cover (8) is provided on the side plate (10) side of the left and right side wall parts (23) with respect to the rotating metal (24) fitted rotatably around the bearing part (6). Bolt (25)
It is detachably installed.

The main tillage cover (5) and the auxiliary tillage cover (8) are provided between the side wall portions (16) and (23) on the rear side or the front side of the side plate (10) located in these gaps. , The connecting plate (26) having a U-shaped cross section is interposed, and the connecting plate (26) and the side wall portion (16)
(23) and the fasteners (27) such as bolts and nuts are tightened to be integrally connected. The ceiling part of this auxiliary tillage cover (8) has the connecting plate (26) part as the main tillage cover (5).
