Pneumatic type rice hill-direct-seeding centralized seeding device

Abstract

The invention discloses a pneumatic type rice hill-direct-seeding centralized seeding device which is composed of a seed box, an outer shell body and a seeding body, wherein the outer shell body is composed of a seed unloading opening, an air inlet, a seed guiding pipe, a seed layer adjusting device, a machine seat, a left end cover, a right end cover, an observing opening plate, a lower outer shell and an upper outer shell; the seeding body composed of a seeding roller, a stopping plate, a rib plate, the air inlet, the seed guiding pipe and a transmission shaft is arranged in the outer shellbody; a hole of the seeding roller is an inclined hole, easiness in filling seeds and feeding seeds is achieved, and accurate rice hill-drop is achieved. The pneumatic type rice hill-direct-seeding centralized seeding device simplifies a seeding process; a modularization design brings convenience to adjustment, installation and disassembling; seed hole forming and accurate seeding are achieved; thus, the seeding device which can achieve accurate rice hill direct seeding is provided.

Description

technical field [0001] The invention relates to the technical field of crop seeding equipment, in particular to a pneumatic hole direct seeding centralized seeding device for rice. Background technique [0002] Rice is one of the main food crops in my country, and the national rice planting area is more than 32 million ha 2 , accounting for about 14% of the country's total arable land, accounting for 20% of the world's rice planting area. At present, rice planting includes two methods: transplanting and direct seeding. With the shortage of high-quality labor in rural areas, direct seeding saves the links of seedling raising, transporting and transplanting, and saves more labor costs. The area of ​​direct seeding rice is increasing year by year. The performance of the seeder will directly affect the productivity of sowing operations and the quality of grain emergence, thereby affecting the growth and yield of seedlings. Improving the operating efficiency of the seeder, deve...
