Helical ridge cleaning device

Abstract

The invention discloses a helical ridge cleaning device which is applied to a corn ridge-planting no-till planter, and belongs to the technical field of agricultural machinery. The helical ridge cleaning device is arranged in front of an opener, and mainly comprises a cutter shaft and a circular knife welded on the cutter shaft; the surface of the circular knife is formed by constant speed movement of element lines which are vertical to the cutter shaft around the cutter shaft; the helical angle of the circular knife at the outer diameter position is minimum, and the helical angle at the inner diameter position is maximum, the helical angle alpha r at the inner diameter position is 48 to 50 degrees, the helical angle alpha g at the average radius position is 26 to 30 degrees, and the screw pitch S is 90 to 110mm, which ensures the straws in the ridge can be successfully cleaned to the field ditch. Compared with the single-disk cleaning device, during operation, the cut straws and stubbles be cleaned to the field ditch when cutting off the straws and stubbles on the ridge so as to prevent the field ditch from clogging; meanwhile, the helical ridge cleaning device has the advantages of small buried depth, no throwing-soil, small power consumption and small damage on the shape of ridge.

Description

technical field [0001] The invention belongs to the technical field of agricultural machinery, and in particular relates to a spiral ridge cleaning device applied to a no-tillage seeder for corn ridge cultivation. Background technique [0002] Ridge farming Conservation tillage is a farming technique that combines conservation tillage technology with traditional ridge farming techniques. Northeast ridge farming areas are the main corn producing areas in my country. For the sustainable development of agriculture, ridge tillage conservation tillage has become the main feature of corn planting in this area , but during the implementation of ridge farming protective tillage technology, due to the thick corn stalks and high amount of corn stalks, when the original ridge no-tillage sowing occurs, the seeder lacks the ridge platform cleaning device, resulting in poor corn no-tillage ridge planting quality and ridge protection. There are problems such as difficulties in tillage promot...

AI Technical Summary

Problems solved by technology

The ridge cleaning device used in my country's corn ridge no-tillage planter is mainly a strip rotary tillage type. Its advantage is that it can form a seed bed that is more suitable for seed germination. The disadvantage is that it consumes a lot of power and the ridge is seriously damaged. not obvious
