Abstract

PURPOSE:To prevent rattling of tilling cover at transferring control position by pressing pin shaft stopping guide rail freely shakable to front and rear on clamping piece by cam. CONSTITUTION:Tilling cover is controlled to transfer in longitudinal direction to machine body and guide rail 4 is transferred relative to guiding part material 3, thus the pin shaft 5 is changed by inserting into the pin hole of the guiding rail 4. The pin shaft 5 after the control is revolved and clamped to a clamping piece 16 of machine body side by a cam 6, then rattling of the pin shaft 5 is stopped.

Description

DETAILED DESCRIPTION OF THE INVENTION Field of Industrial Application The present invention relates to a tilling cover and can be used in a tilling device that is attached to a tractor for tilling.

PRIOR ART AND PROBLEMS TO BE SOLVED BY THE INVENTION The tilling cover of a tilling device often moves back and forth to adjust the plowing depth, etc., but it is difficult to insert the pin shaft into the pin hole of the rail provided in the tilling cover. In this configuration in which the movement adjustment position of the tilling cover is locked, the pin shaft is likely to rattle due to vibrations during tilling work, making it easy to remove and making noise due to rattling.

Means for Solving the Problems The present invention provides a mechanism for covering the rotational upper circumference of the tilling claw (1).
The guide rail (4) supported so as to be movable back and forth relative to the guide member (3) on the 2) side is locked at the movement adjustment position by inserting and removing the pin shaft (5), and the guide rail (4) is supported around the pin shaft (5). The tilling cover has a structure in which a rotating cam (6) is provided so as to be tightened on the machine body (2) side.

Functions and Effects of the Invention When adjusting the tillage cover in the longitudinal direction relative to the body (2) of the tillage device, the pin shaft (5) is moved by moving the guide rail (4) relative to the guide member (3). Replace it with the pin hole of the guide rail (4). When the adjusted pin shaft (5) is rotated, it is tightened by the cam (6) against the member on the body (2) side, so that the rattling of the pin shaft (5) can be stopped.

In this way, attach the pin shaft (5) to the guide rail (4) of the tilling cover.
) by inserting and removing it from the guide rail (4).
), as well as adjusting and determining the movement position of this pin shaft (5).
By rotating the cam (6) around this axis, the cam (6) is tightened and fixed to the member on the machine body (2) side, so the adjustment and fixing operation and configuration are both simple and stable tilling. The adjustable position of the cover can be maintained.

Example In addition, in turning, the tiller body (2) is equipped with a transmission case (
7) is provided with a mast (8) etc. connected to the tractor body on the upper part, and an input shaft for inputting power from the power take-off shaft of the tractor body, and a transmission device for transmitting and rotating the lower plowing shaft (9) from this input shaft. ing. Pipe-shaped brackets (10) are provided on both left and right sides of this transmission case (7), and guide rolls (IIlflZ) are provided above and below the guide member (3) at the outer end of this bracket (!υ). 0

At the opposing position where the pin shaft (5) moves, the guide member (3) is provided with a pin shaft (5) that is movable in the lateral direction.
The pin shaft (5) is provided with an eccentric cam (6), and this cam (6) is connected to the guide member ( 3) to the tightening piece (1) protruding from the circumferential surface of this cam (6).
