Abstract

The invention provides a soil cutting device based on self-excited vibration, which comprises a rotary blade mounted in a shell, a handle welding block welded at the bottom of the rotary blade is inserted into a waist-shaped hole at one end of a spring mandrel in the shell, and a self-excited spring is mounted on the spring mandrel; when rotary tillage operation is carried out, the cutter handle welding block swings in the kidney-shaped hole, one side of the cutter handle welding block makes contact with the end face of the self-excitation spring, the self-excitation spring can be compressed, and therefore self-excitation vibration is generated; when the self-excited vibration frequency is the same as the inherent frequency of the whole cutting device, the best soil cutting effect is achieved, and the resistance reduction and consumption reduction effects are the best at the moment. Threads are machined at the two ends of the spring mandrel and fastened through the nuts, the horizontal position of the spring mandrel is changed by screwing the nuts, the relative position of the kidney-shaped hole in the spring mandrel and the tool handle welding block can be changed, the rotation amplitude of the rotary blade is limited, and the rotary blade vibration cutting device can adapt to tillage vibration cutting work under different soil properties and different working conditions.

Description

technical field [0001] The invention belongs to the technical field of agricultural soil cultivation, and in particular relates to a soil cutting device based on self-excited vibration. Background technique [0002] As the most important farming machinery, the rotary tiller is widely used in plain areas because of its strong soil breaking ability and flat surface after tillage. Defects such as high resistance. According to statistics, the rotary tiller needs to consume a lot of energy in the process of soil crushing, which is about 3 to 6 times that of other tillage operations. Therefore, it is particularly important to study the resistance and consumption reduction of soil tillage, especially rotary tillage. [0003] With the introduction of the theory of vibratory drag reduction cutting, some scholars at home and abroad have carried out related research on vibratory subsoiling technology and achieved fruitful results. At present, domestic research on self-excited vibrat...
