Rapeseed precision rotary planter matched with a hand tractor

Abstract

The invention belongs to the technical field of seeders and particularly relates to a small rapeseed precision rotary sower associated with a walking tractor; the small rapeseed precision rotary sower comprises a fertilizer feeding unit, a positive and negative pressure working unit and a rotary tillage unit; the positive and negative pressure working unit comprises a positive and negative pressure machine and a positive and negative pressure combined seed-metering device; the positive and negative pressure combined seed-metering device is connected with a fixed plate of the seed-metering device through a bolt; the fixed plate of the seed-metering device is equidistantly welded above a front positive and negative pressure distribution pipe and a rear positive and negative pressure distribution pipe; the positive and negative pressure distribution pipes are integrally connected with the machine rack connecting plates at left and right ends through welding; and a machine rack fixed plate welded before the positive and negative pressure distribution pipes forms a three-point linkage together with a left machine rack hanging rod and a right machine rack hanging rod. The small rapeseedprecision rotary sower saves sowing time and effort and has the advantages of high sowing precision, good uniformity, low re-sowing rate, low sowing leakage rate, strong stubbing ability, as well as high tillage operation quality, which can achieve the combined operation of fertilization, precision sowing and rotary tillage. The small rapeseed precision rotary sower can be also used for precisiondirect sowing of other spherical small-diameter seeds.

Description

technical field [0001] The invention relates to the technical field of seeders in agricultural machinery, in particular to a rapeseed precision rotary sowing machine matched with a walking tractor. Background technique [0002] At present, the domestic rapeseed planting is still dominated by the traditional planting mode of growing seedlings first and then transplanting or artificial slipping, thinning and setting seedlings after sowing, which is labor-intensive and low in production efficiency; mechanized planting is mainly direct seeding, that is, using equipment sockets The seed drill of the wheel type seed meter mixes the rapeseed with chemical fertilizers and sediment or mixes a certain proportion of fried rapeseed in the seed before sowing. Moreover, the vertical socket wheel seed metering device itself will squeeze the rapeseed and cause damage during the working process. After several damaged rapeseeds condense into balls, it is easy to block the socket and cause mis...
