A self-excited vibrating subsoiling shovel

Abstract

The invention discloses a self-excited vibrating subsoiling shovel, which comprises a shovel handle, an upper soil retaining cover plate, a positioning flat-head bolt, a left earth retaining plate, a right earth retaining plate, an adjusting bolt, a coil spring, a blade and a fastening bolt. The shovel handle is respectively provided with an adjustment mounting hole, an upper soil retaining cover plate mounting hole, a limit guide chute, a coil spring mounting seat, an adjusting bolt hole, a shovel edge mounting seat and a shovel tip, and the shovel tip is located on the shovel handle The bottom and the front side of the shovel handle are set; the invention can improve the subsoiling effect, reduce the working resistance, and enhance the adaptability of the self-excited vibration subsoiling shovel; during work, it does not require additional tractor power consumption, but uses the screw The expansion and contraction of the spring drives the shovel blade to vibrate, thereby quickly loosening the soil and reducing drag; when the soil conditions and working methods change, the adjusting bolt can be adjusted to change the vibration parameters of the self-excited vibration deep loosening shovel, which has a simple structure , low energy consumption, strong adaptability and easy installation.

Description

technical field [0001] The invention belongs to the technical field of agricultural machinery, and in particular relates to a self-excited vibration subsoiling shovel. Background technique [0002] At present, there are two main methods of soil tillage vibration resistance reduction: forced vibration and self-excited vibration. The forced vibration farming method can achieve good drag reduction effects under specific frequency, amplitude, soil conditions and working methods. However, forced vibration requires an additional additional vibration device, which also increases the cost and power consumption of the system. Moreover, its adaptability is limited, that is, when soil conditions, working methods, etc. change, if the vibration parameters such as vibration frequency or amplitude are not adjusted, the power consumption of the system may increase sharply. [0003] The principle of self-excited vibration is the core of the application in soil cutting mechanics: to make th...

AI Technical Summary

Problems solved by technology

[0004] However, the self-excited vibration in the prior art cannot well adjust the subsoiling ability and achieve an improved subsoiling effect during actual work, and the working resistance is relatively large, easily affected by soil and foreign objects, and the adaptability is not enough. Small scope of application

In addition, it is difficult to adjust the vibration parameters of the subsoiler shovel to adapt to changes in soil conditions, working methods, etc.

Moreover, the existing self-excited vibrating subsoiling shovel also needs to receive the power drive of an additional tractor, which consumes energy
