Abstract

The invention provides a sowing machine for dry land. The sowing machine comprises a traction frame, driving land wheels, a rack, roller type seeder units, a ditching depth wheel, furrow openers and covering devices, wherein the traction frame is arranged at the front end of the rack; the ditching depth wheel and the plurality of roller type seeder units are respectively arranged at the front and the back of the rack; the furrow openers and the covering devices are respectively arranged at the fronts and the backs of all the roller type seeder units in a way of one-to-one correspondence; the roller type seeder units are fixed on a transmission shaft; the transmission shaft is fixed on the rack; the two ends of the transmission shaft are respectively provided with the driving land wheel. The sowing machine for the dry land is simple in mechanical structure and convenient to use, is capable of adjusting plant spacing and accurately sowing so as to save seeds, and is rapid in sowing speed, uniform in sowing and good in sowing effect.

Description

technical field [0001] The patent of the invention belongs to the technical field of agricultural machinery, and specifically relates to a device for dry land. Background technique [0002] Most precision seeders can sow a variety of crops. By replacing the seeding discs (wheels) or seeding rollers with different apertures, the seeder can adapt to the sowing requirements of various crop seeds. Change the size of the hole or increase the hole forming mechanism so that it can meet the requirements of hole sowing; change the working speed of the seed meter to meet the requirements of different plant distances. All this increases the versatility of the planter. [0003] In order to meet the requirements of different regions, different soils, and different soil preparation conditions, most seeders are equipped with various types of openers (double disc type, sliding knife type, etc.) wheels, wide wheels, narrow wheels, etc.), for selection. It can be matched with tractors of v...
