Abstract

The invention discloses a seeder depth control system. Land unevenness is collected by an ultrasonic sensor and converted into an electrical signal; the electrical signal is transmitted to a PLC to process; processing results are output an analog output module; action of an electromagnetic valve is controlled; an oil cylinder is driven to descend or ascend; a ditcher depth regulator is controlled in real time. Seeding depth can be regulated quickly and accurately. Seeding depth of a seeder can be precisely controlled effectively. Related parameters can be set in real time through an embedded integrated touch screen. The touch screen is communicated with the PLC through a communication port. Related information acquired is centrally displayed in real time. The seeder depth control system has the advantages that the quality of crop planting is guaranteed, the copying form of each component of a seeding unit of the precision seeder can be designed into independent copying, and seeding depth can be independently controlled according to surface fluctuation.

Description

technical field [0001] The invention belongs to the field of agricultural machinery control, in particular to a seeder depth control system. Background technique [0002] The sowing depth of the precision seeder is one of the indicators strictly required in the sowing process. It has a greater impact on the yield. The sowing depth is the thickness of the soil layer covered by the seeds implanted in the ground. The thickness of the soil layer on the seeds with the same horizontal depth is also different. Therefore, to maintain the same sowing depth, it is necessary to control the openers of each sowing unit to move up and down with the undulation of the ground, that is, profiling. In order to maintain the same depth of penetration, the current planters mostly use mechanical profiling devices, which have many advantages such as relatively simple structure, low cost, no need for external energy control, and convenient maintenance. However, the profiling accuracy is relatively l...
