Embodiment

[0018] Embodiment: The combination device for rice hole sowing quantitative seeding according to the present invention includes a seeding shaft 1 , two side baffles 2 , a blank filling wheel 3 , an involute type seeding wheel 4 and a transmission sprocket 5 . The two side baffles 2, the blank filling wheel 3, and the involute type seeding wheel 4 are all installed on the seeding shaft 1, and the seeding shaft 1 passes through the two side baffles 2, the blank filling wheel 3, the involute type seeding wheel 4, and The open-line type seeding wheel 4 is combined as a whole. The position where the two side baffles 2, the blank filling wheel 3, and the involute type seeding wheel 4 are installed on the described seeding shaft 1 is a hexagonal shaft structure, so that the two side baffles 2, the blank filling wheel 3, the involute The linear seeding wheel 4 is positioned radially. The two ends of the hexagonal shaft structure of the seed metering shaft 1 are respectively equipped ...

Abstract

The invention discloses a hole sowing and quantitative seed-metering combined device for paddy rice. The hole sowing and quantitative seed-metering combined device comprises a seed-metering shaft, twoside baffle plates, blank filling wheels, involute linear seed-metering wheels and a transmission chain wheel, wherein the two side baffle plates, the blank filling wheels and the involute linear seed-metering wheels are mounted on the seed-metering shaft; the sum of the involute linear seed-metering wheels and the blank filling wheels is 8, the involute linear seed-metering wheels can be adjusted between 3 to 8 sections; the detached involute linear seed-metering wheels can be replaced with the blank filling wheels. According to the hole sowing and quantitative seed-metering combined devicefor the paddy rice, seed-metering mold holes are of an involute shape; the seed-metering mold holes realize hole sowing and seed metering through a manner of separating by space teeth; meanwhile, paddy rice seeds are easy to fill and release; the hole sowing and quantitative seed-metering combined device for the paddy rice is simple in structure and is applicable to precision hole sowing of the paddy rice, the working efficiency and the sowing precision can be remarkably improved.

Description

technical field [0001] The invention relates to the technical field of sowing of agricultural machinery, in particular to a rice hole sowing quantitative seeding combined device for concentrated rice sowing. Background technique [0002] Rice is an important ration crop in my country, and planting is still a weak link in the whole mechanization of rice. Mechanized rice planting includes machine transplanting and machine direct seeding. Machine transplanting has the characteristics of strong tillering ability, perfect agronomic technology and stable yield. It is the main rice mechanized planting method in Japan, South Korea and my country; The machine-directed planting method, which saves labor and costs, has developed rapidly in recent years and has become an important method of rice mechanized planting. The sowing quality of machine direct seeding mainly depends on the seeding performance of the seed metering device. [0003] Most of the currently used rice metering device...
