Combined mechanism for crop straw pullout and cutting

Abstract

The invention relates to the field of agricultural machinery, in particular to a combined mechanism for crop straw pullout and cutting. Crop straws are uprooted by a straw pullout mechanism, and thenthe crop straws are cut by a straw cutting mechanism, and the crop straws are cut into segments for convenient recycling and utilization, so that integrated operations of crop straw pullout and cutting are realized. In the conveying mechanism, one or more transition servo rotors installed at the rear part of the straw pullout mechanism play roles of crop straw supporting and conveying, the pulledcrop straws are conveyed between the upper and lower guide servo rotors, and then conveyed to the cutting mechanism through the guide servo rotors, so that the crop straw cutting according to a set length is conducive to being realized, and then the cut crop straws are collected. Therefore, compared with an existing technology, the technology can significantly improve the operation quality and production efficiency.

Description

technical field [0001] The invention relates to the field of agricultural machinery, in particular to a combined mechanism for removing and cutting crop stalks. Background technique [0002] my country is the world's largest cotton producing country. When the production is high, the planting area of ​​more than 20 provinces and regions in the country reaches 90 million mu. It is an important economic crop in my country's agricultural production. For thousands of years, the cotton stalks after cotton picking are artificial Pulling and cleaning, cotton stalk removal and cleaning has become a very heavy physical work for cotton planting. This work is heavy and inevitable, and there is no good solution once and for all. For a long time, agricultural machinery experts from scientific research departments and enterprises in my country have invested a lot Manpower and material resources. In recent years, some technicians have used two chains to clamp the stalks for the stalk pulling ...

[0002] my country is the world's largest cotton producing country. When the production is high, the planting area of ​​more than 20 provinces and regions in the country reaches 90 million mu. It is an important economic crop in my country's agricultural production. For thousands of years, the cotton stalks after cotton picking are artificial Pulling and cleaning, cotton stalk removal and cleaning has become a very heavy physical work for cotton planting. This work is heavy and inevitable, and there is no good solution once and for all. For a long time, agricultural machinery experts from scientific research departments and enterprises in my country have invested a lot Manpower and material resources. In recent years, some technicians have used two chains to clamp the stalks for the stalk pulling test. However, due to the uneven size and density of the cotton stalks, the high pull-out force requirements lead to the failure of the equipment to pull out and Severe broken stalks cannot meet the agronomic requirements

So so far, there is still no mature machine that can meet the requirements of cotton stalk pulling, let alone cutting the cotton stalks into 2-8cm sections for recycling when the cotton stalks are pulled out.
