Abstract

The invention relates to an intelligent air-suction seeder unit, which belongs to the technical field of seeders. By adopting the intelligent air-suction seeder unit, the accurate control of a planting depth and a plant distance can be realized, the seeds can be precisely fed in place, the seeds can be saved, and the crop yield can be increased. A pressure control oil cylinder of a feeler mechanism is fixedly installed on a unit fixing frame and used for controlling a furrowing depth of a furrowing disc of a seeding mechanism, a depth limiting wheel pressure sensor of the feeler mechanism is installed on a tail end of an a depth limiting wheel adjusting handle of a depth limiting mechanism, and the depth limiting wheel pressure sensor is matched with the pressure control oil cylinder and used for transmitting a signal to the pressure control oil cylinder; and a seed metering device of the seeding mechanism is an electric control air-suction seed metering device. By adopting the hydraulic oil cylinder and the depth limiting wheel pressure sensor matched with each other, the hydraulic oil cylinder outputs stable setting pressure according to the signal and the depth limiting wheel pressure sensor, the change of seed quantity and unit weight of a seed box does not influence the seeding depth, the stable work of a furrowing device can be ensured, and the consistency of the furrowing depth and the seeding depth can be ensured.

Description

technical field [0001] The invention belongs to the technical field of seeders, in particular to an intelligent air-suction seeder unit. Background technique [0002] Sowing operation is a key link in agricultural production. From the earliest artificial sowing to the rise of large precision seeders, the efficiency and quality of sowing operations have attracted more and more attention. At present, most of the domestic seeders have seeder monitoring systems, but only simple monitoring has not realized the combination of monitoring. With the development of science and technology, the demand for intelligent control of seeders is getting higher and higher, which requires the realization of precision seeding machinery. intelligent control. Contents of the invention [0003] The object of the present invention is to provide an intelligent air-suction type seeder unit, which can realize precise control of planting depth and plant spacing, make seeds in place accurately, save se...
