Abstract

The invention which belongs to the technical field of seeders concretely relates to an internal inflation blow type compatible precision seed sowing device for rape and wheat. The precision seed sowing device has a closed cavity formed by connecting a seed sowing roller with cover casings, and the closed cavity is divided into a seed protecting zone, a seed inflating zone, a seed clearing zone and a seed unloading zone. The precision seed sowing device comprises the cover casings, the seed sowing roller, a seed protecting plate, a seed conveying tube, an air inlet tube, air separating plates, a seed unloading port, a seed sowing tube and the like; the cover casings are connected into one body through bolts, one cover casing is provided with a balance pore, and the part of one cover casing connected with the seed sowing tube is provided with the seed unloading port; the seed protecting plate and the air separating plates are welded on the inner side of one cover casing; the air inlet tube is welded on the outside of one cover casing; the seed conveying tube which traverses through the circular hole in the middle of one cover casing has a clearance fit with the seed sowing roller; and holes are uniformly distributed on the seed sowing roller along the circumferential direction, the seed sowing roller has a clearance fit with the cover casings, the seed protecting plate and the air separating plates, the seed unloading zone is connected with the positive pressure end of a fan through the air inlet tube, and the seed unloading zone adjusts the flow of an air chamber through the balance pore.

Description

technical field [0001] The invention relates to the technical field of sowing in agricultural machinery, in particular to an internal air-blowing type precision seed metering device for rapeseed and wheat. precision seeding. Background technique [0002] The precision metering device is widely used at home and abroad to sow row crops such as corn, soybean, cotton, sorghum, and sugar beet. Its advantages are: saving good seeds, no need for thinning, evenly distributed plants in the field, achieving reasonable dense planting, and benefiting the growth of seedlings. However, the existing precision seed metering devices are mainly used in large-grained crops, and generally can only achieve one kind of crop seeding, and the versatility is poor; and the existing mechanical precision seed metering devices in There is a serious problem of hole blockage; the main disadvantages of the pneumatic seed metering device are the high processing accuracy requirements of the seed metering d...
