Tilling depth on-line measuring system and method of agricultural implements subsoiling working

Abstract

The present invention discloses a tilling depth on-line measuring system of agricultural implements subsoiling working. The system comprises a tilling depth measurement sensor and a data processor connected with the tilling depth measurement sensor, the tilling depth measurement sensor comprises a first inclination angle sensor arranged on a lower pull rod and a second inclination angle sensor arranged on a plow frame, and the data processor is used to receive the inclination angles of the first and second inclination angle sensors, and real-timely calculate the tilling depth according to a following formula. According to the present invention, the inclination angle sensors are used to measure the tilling depth, so that the influences of the uneven ground and the straw fertilizer blocking on the depth measurement results of the distance measuring sensors are solved. Moreover, the second inclination angle sensor arranged on the plow frame can monitor the level change state of a subsoiling plow, so that the situation that the plow is lifted to plough shallowly or a small plow is replaced to plough shallowly during the subsoiling process is avoided, and the accurate tilling depth measurement is provided.

Description

technical field [0001] The invention relates to a system and method for real-time monitoring of subsoiling of agricultural machinery and tools, in particular to a system and method for real-time measurement of tillage depth of subsoiling of agricultural machinery and tools. Background technique [0002] At present, my country's agricultural production mode has realized an era dominated by mechanized operations. With the transfer of rural labor force to cities, agricultural machinery is widely used in various fields of agricultural production, and agricultural production is increasingly dependent on agricultural machinery. The level of agricultural mechanization is getting higher and higher, and farmers have higher and higher requirements for the quality of agricultural machinery field operations. How to improve the management level of field operations and thus increase the yield of grain crops is a new challenge for the agricultural machinery management department. [0003] ...

AI Technical Summary

Problems solved by technology

[0005] The purpose of the present invention is to completely solve the problem of unqualified plowing depth due to the backwardness of detection means and the influence of human factors, and to provide an on-line measurement system and method for plowing depth of agricultural machinery and tools for subsoiling operations, which can be used on the lower rod and subsoiling plow Install an inclination sensor each, and use the tillage depth measurement module of the vehicle-mounted terminal to real-time subsoil depth
