Problems solved by technology

[0002] No matter what kind of technical means is used in the traditional soil mechanical resistance measurement method, the collected soil mechanical resistance values ​​are limited to some scattered points in the farmland, the accuracy will be greatly limited, the working process is intermittent, and the test efficiency is not high
Although the telemetry method can get rid of the heavy mechanical structure and cause minimal damage to the ground, due to the complexity of the soil, soil sample research is currently only carried out in the laboratory, and it does not have the conditions for field application

Embodiment Construction

[0010] The specific embodiment of the present invention is described below in conjunction with accompanying drawing:

[0011] exist figure 1 Among them, the present invention consists of a frame 1, a force sensor 2, a three-point suspension frame 3, a displacement sensor 4, a profiling wheel 5, a blade 6, a safety pin 7, a hydraulic cylinder 8, and a slider 9. The subsoiling shovel passes through The three-point suspension frame 3 is connected with the tractor to realize the continuous measurement of soil mechanical resistance. The tailstock of the hydraulic cylinder 8 is installed on the two channel steels in the middle of the frame 1, the piston rod is connected with the slider 9, and the blade 6 is connected with the slider. The block 9 is hinged. When the cultivated land has little resistance and the shovel 6 is not damaged, the hydraulic cylinder 8 prevents the shovel 6 from moving backward through the slider 9. The resistance of the hydraulic cylinder 8 will exceed the ...

Abstract

The invention discloses a subsoiler capable of measuring the mechanical resistance of soil continuously, and aims to measure the mechanical resistance of the soil. A displacement sensor is used for measuring the tillage depth of the subsoiler and installed between a machine frame and a profiling wheel. A scraper knife of the subsoiler is hinged to a sliding block, and a hydraulic cylinder is connected with the sliding block. Under the condition that the tillage resistance is not large and the scraper knife can not be damaged, the hydraulic cylinder prevents the scraper knife from moving backwards. In the tillage process, if the scraper knife meets foreign bodies, the value of the resistance on the scraper knife exceeds the set pressure value of the hydraulic cylinder, the hydraulic cylinder contracts, and the scraper knife moves backwards and avoids the foreign bodies. The scraper knife is connected with a force sensor used for measuring the resistance of tillage.

Description

technical field [0001] The invention relates to a subsoiling shovel capable of continuously measuring soil mechanical resistance, in particular to the design of a device capable of automatically avoiding foreign objects in cultivated land. We can judge the degree of shovel by monitoring the change of the hydraulic cylinder pressure value in the avoiding device Whether it encounters foreign objects, remove the abnormal soil mechanical resistance value, so as to measure the soil mechanical resistance value more accurately. Background technique [0002] No matter what technical method is used in the traditional soil mechanical resistance measurement method, the collected soil mechanical resistance values ​​are limited to some scattered points in the farmland, the accuracy will be greatly limited, the working process is intermittent, and the test efficiency is not high. Although the telemetry method can get rid of the heavy mechanical structure and cause minimal damage to the gr...
