Intelligent fine soil preparation device

Abstract

The invention relates to an intelligent fine soil preparation device, and belongs to the technical field of agricultural machinery. The intelligent fine soil preparation device comprises a sensing control circuit, a deep ploughing knife roll assembly (4) supported in the front of a machine frame (1), a fine preparation knife roll assembly (17) and a pressing wheel (19), wherein the fine preparation knife roll assembly (17) and the pressing wheel (19) are supported in the back of the machine frame (1) and driven by a hydraulic motor (16). The signal input end of the sensing control circuit is connected with a force sensor (26) located between the deep ploughing knife roll assembly (4) and the fine preparation knife roll assembly (17), the control output end of the sensing control circuit is connected with a stepping motor (13), and the motion output end of the stepping motor (13) is connected with an adjusting oil cylinder (10) located in an oil transportation channel of a hydraulic motor (16) through a transmission mechanism. The sensing control circuit comprises an intelligent control device outputting corresponding signals for controlling the opening position of the adjusting oil cylinder according to the signals of the force sensor (26). According to the intelligent fine soil preparation device, the secondary fine ploughing operation strategy is determined in an intelligent mode, and standard requirement of fine soil preparation of vegetable fields is met actually.

Description

technical field [0001] The invention relates to a plowing machine, in particular to an intelligent fine land leveling device, which belongs to the technical field of agricultural machinery. Background technique [0002] In the whole process of mechanization of vegetable production, soil preparation is the most basic and one of the most important links. Vegetable production has the highest requirements for soil preparation. The surface soil needs to be finely crushed and loose, the surface should be flat, and the ridges and furrows should be straight, so as to provide good conditions for seed germination or vegetable seedling growth; etc.) has gradually become the key to the application and development of vegetable precision direct seeding technology and high-speed transplanting technology, and is the basis for subsequent mechanized operations. [0003] According to the applicant's knowledge, most of the existing open-field vegetable soil preparation equipment is borrowed fr...

Problems solved by technology

The transmission ratio of the two shafts is fixed, and the rotating speed of the crushing shaft cannot be adjusted in time for large soil blocks in operation, thus affecting the quality of crushed soil on the ridge-shaped surface; secondly, the internal structure of the gearbox is compact during the movement process, resulting in The heat is very large, and the large shape and volume of the gearbox affect the quality of the side of the ridge; at the same time, the pressure roller behind it is passively rotating, and the soil flatness of the ridge surface after operation is not good.
