Description

Disk cover with scale indication

technical field

The invention relates to an agricultural machine tool, which belongs to the field of agricultural machinery, and in particular provides a disc cover device with scale indication, which can realize multi-directional precise indication and adjustment of the opening angle, inclination angle, cover width and cover depth of sowing cover soil.

Background technique

The disc cover device is the most common cover device installed on the seeder used in agricultural production in my country at present. The cover disc of the traditional double disc cover device cannot be adjusted, which makes the adaptability and operation quality of the sowing operation poor. In recent years, the adjustable disc cover device has been applied in agricultural production, but due to the problems in its structural design, the existing disc cover device has few adjustment parameters, the adjustment operation is inconvenient, and the adjustment amount cannot be controlled, which affects the The quality of soil covering operation reduces the operation efficiency of sowing.

Contents of the invention

In order to solve the above problems, the present invention provides a multi-directional adjustment, convenient and quick adjustment, and controllable scale disc soil cover device with scale indication.

The present invention is realized by adopting the following technical solutions: a disc cover device with scale indication, including a hitch device, a locking device, an adjustment device and a disc, etc., wherein the hitch device serves to connect the seeder and the depth adjustment disc The locking device plays the role of connecting and positioning locking, and the adjusting device plays the role of multi-directional adjustment of depth adjustment, width adjustment, opening angle adjustment and inclination adjustment. The adjustment angle value is engraved on the outside of the arc groove at the outer end of the width adjustment plate and the opening angle adjustment plate, and the covering soil width value is engraved on the outside of the width adjustment mother plate; the degree of rotation of the arc groove on the depth adjustment plate corresponds to the depth scale value on the outside Proportional relationship, adjustment angle value, rotation angle adjustment range 0-90 ^o , cover soil width value, cover soil width adjustment range 400-600mm.

Compared with the prior art, the present invention has the following advantages:

1. It can realize the multi-directional adjustment of the overburden opening angle, inclination angle, overburden width and overburden depth, and the overburden quality is good and the adaptability is strong;

2. Equipped with adjustable scale value, convenient measurement, controllable scale and fast adjustment.
