Five-rod hole forming type no-tillage hole sowing mechanism

Abstract

The invention discloses a five-rod hole forming type no-tillage hole sowing mechanism and belongs to agricultural machines. The five-rod hole forming type no-tillage hole sowing mechanism comprises a rack, a left supporting part, a right supporting part, a five-rod hole forming part, a ratchet wheel intermittent mechanism and a seed discharging mechanism. The five-rod hole forming part comprises a five-rod mechanism and a duckbilled hole forming mechanism, the five-rod mechanism serves as a track forming mechanism, drives the duckbilled hole forming mechanism during motion, and is matched with the ratchet wheel intermittent mechanism and the seed discharging mechanism, and the no-tillage sowing process of seed discharging, seed receiving, hole forming and seed falling can be repeatedly completed. The five-rod hole forming type no-tillage hole sowing mechanism has the advantages that the structure is simple, mounting and maintenance are easy, duckbilled hole forming can be directly carried out on the premise of not touching straw stubbles or distributing soil, no-tillage sowing is completed, and the problems that when an existing no-tillage sowing machine carries out sowing in a shearing mode and a removing mode, power consumption is large, environment pollution is serious, and winding and blocking are prone to be caused when a large amount of straw exists are avoided.

Description

technical field [0001] The invention belongs to the field of agricultural machinery and relates to a five-rod hole forming no-tillage hole sowing mechanism. Background technique [0002] Conservation tillage is an effective way to transform the traditional farming system of dry land in my country, and it is an important strategic measure to improve the ecological environment and achieve sustainable development. It can not only reduce consumption and operating costs, but also help to conserve water and moisture, and improve soil fertility and drought resistance . As one of the four major contents of conservation tillage, no-tillage seeding is the key technology to implement conservation tillage. For this reason, researchers at home and abroad have developed a series of no-tillage seeders for no-tillage seeding technology. In order to ensure the smooth sowing of seeds, the existing no-tillage seeder mainly adopts two methods. One is to use a disc cutter to cut Straw (root stu...

AI Technical Summary

Problems solved by technology

[0003] The purpose of the present invention is to address the above existing problems, to provide a five-bar hole-forming no-tillage hole sowing mechanism, to avoid the large power consumption of the existing no-tillage seeder when using two methods of cutting and removing. , the environment is seriously polluted, and when the amount of straw is large, it is easy to cause problems such as entanglement and blockage. It is possible to complete no-tillage sowing without moving the straw residue and disturbing the soil.
