Precise direct seeding device with lateral seed guide function

Abstract

The invention discloses a precise direct seeding device with a lateral seed guide function. The precise direct seeding device comprises a shell, a lateral seed guide pipe, a rotating shaft and a plurality of seed cavity dividing brushes, wherein the seed cavity dividing brushes are arranged in the shell; the seed cavity dividing brushes are connected to the rotating shaft, and are uniformly arranged around the circumferential direction of the rotating shaft, thereby forming a flexible buffer disk; two adjacent seed cavity dividing brushes and the inner wall of the shell form seed cavities; theside face of the shell is provided with a pipe interface; the pipe orifice of the lateral seed guide pipe is communicated with the pipe interface; the bottom of the shell is provided with a seed outlet; when the rotating shaft drives the seed cavity dividing brushes to rotate, the seed cavities passing by the pipe interface are communicated with the lateral seed guide pipe; when the seed cavitiespass by the seed outlet, the seed cavities are communicated with the seed outlet. The precise direct seeding device is simple in structure, and is suitable for changing strip seeding of quantitatively-conveyed seed stream into hole seeding; meanwhile, a lateral seed guide effect is achieved. Moreover, the situations of seed clamping and seed damage are reduced effectively, stable running of the flexible buffer disk is ensured, and the hole forming property is enhanced greatly.

Description

technical field [0001] The invention relates to an agricultural machine, in particular to a side-guiding rice precision direct seeding hole-forming device. Background technique [0002] Rice is a food crop with a large planting area and a large yield per unit area in my country. my country's rice production ranks first in the world. Rice production is related to my country's food security, agricultural efficiency, and farmers' income. At present, the mechanization level of rice planting in my country is relatively low compared with that of other crops. The key to solving this problem is to optimize the sowing quality of rice planting machinery. The existing rice planting methods mainly contain direct seeding and transplanting. Live broadcast is divided into manual sowing, mechanical drill sowing, mechanical hole sowing and so on. The mechanical drilling is done in rows but not into holes. The existing hole forming mechanism can basically realize hole formation, but there i...

AI Technical Summary

Problems solved by technology

The mechanical drilling is done in rows but not into holes. The existing hole forming mechanism can basically realize hole formation, but there is a problem that the seeds are stuck at the entrance or cut off by the rotating compartment plate when the seeds are injected, which affects the sowing problem and the seed damage rate. Higher, affects the emergence rate of rice, and cannot meet the planting requirements of rice in rows and holes
