A dual-purpose sowing device for hole sowing of wheat and rice strips

Abstract

The invention relates to a dual-purpose sowing device for hole sowing of wheat and rice, aiming at improving the utilization rate of the sower in a wheat and rice rotation area. Including: a seeding unit, a seeding unit and a sowing unit; the seeding unit includes a seed metering device, a seed metering shaft, an inoculation funnel, a plastic seeding tube, and the plastic seeding tube is inserted into a seeding tube; the seeding unit It includes a seed guide tube and a sorting mechanism, wherein the sorting mechanism includes a crank, a connecting rod, a seed baffle, a baffle fixing shaft, and a shaft sleeve. The seed guide tube is fixed on the frame, the upper end communicates with the seeding unit, and the lower end communicates with the sowing unit. The unit is fixed and connected, the crank of the sorting mechanism is fixed on the shaft of the seed meter, the cylindrical protrusion at one end is hinged to the upper end of the connecting rod, the lower end of the connecting rod is connected to one end of the fixed shaft of the baffle, and the fixed shaft of the baffle passes through the seed tube and is installed on the seed In the shaft hole of the baffle plate, a shaft sleeve is installed between the fixed shaft of the baffle plate and the seed guide pipe; the sowing unit includes a dovetail type sowing opening and a diversion stopper, and the diversion stopper is installed on the platform at the seed outlet.

Description

technical field [0001] The invention relates to a dual-purpose sowing device for hole sowing of wheat and rice strips, which belongs to the field of agricultural machinery. Background technique [0002] Direct seeding of rice is a cultivation method that directly sows seeds in the field without raising seedlings and transplanting. Large-scale direct seeding of rice can save a lot of labor and alleviate the contradiction of labor seasonal tension. It is of great significance to realize light, professional and large-scale rice production, and has broad prospects for promotion. However, rice needs to be sown in holes, and wheat needs to be sown in wide seedling strips. For wheat-rice continuous cropping areas, two different types of seeders are required for two-season sowing. The utilization rate of the seeders is low and the planting cost is high. Contents of the invention [0003] The purpose of the present invention is to provide a dual-purpose sowing device capable of re...
