Technical Field

The invention belongs to a subsoiling machine, in particular to a vibrating type subsoiling device.

Background

The soil deep scarification can effectively break a hard plough bottom layer formed by ploughing or stubble cleaning for a long time, greatly improve the water permeability and air permeability of the soil and improve the crop yield. The self-excited vibration subsoiling is a subsoiling mode with low energy consumption and high efficiency. In the existing vibration subsoiling machinery, a plough shovel is fixedly connected with a plough column, and when the working resistance exceeds the adjustment range of a spring or the soil penetration angle is improperly adjusted, the plough shovel is easy to break. In addition, when the cultivation speed is high or the soil is hard, the phenomenon that the excitation spring is completely compressed and loses the self-excited vibration performance is easily caused. In view of the above, there is an urgent need for a subsoiler that is capable of maintaining a self-excited vibration state at all times.

Referring to fig. 3, 8 and 9, the self-adjusting self-excited vibration subsoiler operates as follows: when the device works, the motor 6-2 drives the cam 6-1 to rotate.

When the working speed is too high or the soil resistance is too large, the spring 12-5 is completely compressed along with the integral anticlockwise rotation of the subsoiler, and the self-excited vibration performance is lost; at the moment, the cam 6-1 is in contact with the connecting rod plate 7, the whole deep scarification device rotates clockwise under the action of the pushing force of the cam 6-1 on the connecting rod plate 7, the spring 12-5 recovers a part of self-excited vibration performance, and the reciprocating operation is carried out until the normal working state is recovered.
