Ground clearance monitoring system for crushing blades of cassava stem crushing and field returning machine

Abstract

The invention discloses a ground clearance monitoring system for crushing blades of a cassava stem crushing and field returning machine. The system comprises a profiling detection mechanism for detecting ground fluctuation, a hydraulic actuating mechanism for controlling the blades to lift, and a microprocessor in signal connection with the profiling detection mechanism and the hydraulic actuatingmechanism. The invention further discloses a cassava stem crushing and field returning machine monitoring system loaded with the system, and the monitoring system further comprises a vehicle-mountedterminal and a satellite positioning device. The informatization and the automation level of the cassava stem crushing and field returning machine are effectively improved, the problem that the cassava crushing and field returning effect is affected due to the fact that the ground clearance of the cassava stem crushing and field returning machine cannot be automatically adjusted along with the uneven ground surface due to topographic changes is solved, the operation efficiency of the cassava stem crushing and field returning machine is improved, and technical support is provided for supervision of operation efficiency.

Description

technical field [0001] The invention relates to a crop stalk crushing and returning machine, in particular to a ground clearance monitoring system for crushing blades of the cassava stem crushing and returning machine. Background technique [0002] Cassava is a kind of economic crop introduced and planted in the southern region of my country in the 1980s and 1990s. In addition, the southern hilly landform and supporting agronomic facilities cannot keep up with the perfect pace, and there are relatively few researches on its production and harvesting and other agricultural machinery and equipment, especially when it is related to cassava. Agricultural machinery and equipment related to stalk harvesting and processing. At present, cassava production operations need to meet higher requirements for mechanical production operations, and the existing cassava stalk crushing and returning machines still have low operating efficiency, and cannot effectively solve various internal and ...

AI Technical Summary

Problems solved by technology

If the ground clearance of the blade is too large, the crushing of cassava stalks is not thorough enough, which will seriously affect the mechanical harvesting and cause the cassava stalks to germinate in the next year and affect the planting of crops; Knives wear and damage shallow cassava roots

At present, the ground clearance of cassava stalk shredder blades has not been monitored in China, which limits the development demand of cassava industry to a certain extent.

[0003] When the cassava stem crushing and returning machine is operating in the field, due to the undulating state of the ground surface during operation, the ground clearance of the crushing blade cannot follow the fluctuation of the ground surface, which will cause different lengths of remaining cassava stems after crushing, and the effect of crushing and returning to the field is difficult to guarantee

The ground clearance of the crushing blade is one of the important operating parameters of the straw crushing and returning machine. At present, the domestic straw crushing and returning machine is still in the mechanical operation stage, and there is no measuring device and control method for the ground clearance of the crushing blade in China.
