Embodiment Construction

[0010] The embodiments of the present invention will be described in detail below with reference to the accompanying drawings. A no-tillage seeder has three cutter discs for stubble-breaking and straw-breaking and anti-blocking operations. On the power drive shaft 4, the left active cutter disc 3 for cutting straw and the right active cutter disc 2 for cutting straw are fixed to each other symmetrically. On the drive shaft 4, the stubble-breaking driven cutter disc 1 is rotatable at the position between the left active cutter disc 3 for stalk breaking and the right active cutter disc 2 for stalk breaking. SizeФ 1 Larger than the outer diameter dimension Ф of the left and right active cutter heads 3 and 2 for cutting straw 2 , the rotation direction of the left and right active cutter discs 3, 2 is the same as the rotation direction of the stubble-breaking driven cutter disc 1, and the rotational speed is different. 6 and the stubble-breaking blade 5 of the stubble-breaking d...

Abstract

The invention discloses a three-cutter stubble cutting and straw cutting anti-blocking operation monomer of a no-tillage planter and belongs to agricultural machinery. Left and right straw-breaking driving cutters are fixedly arranged on a power drive shaft oppositely; a stubble-cutting driven cutter rotationally sleeves outside the part between the left and right straw-breaking driving cutters on the power driver shaft; the outer diameter of the stubble-cutting driven cutter is greater than those of the left and right straw-breaking driving cutters; straw-breaking blades of the left and right straw-breaking driving cutters and a stubble-cutting blade of the stubble-cutting driven cutter all are Archimedean spiral lines. The monomer is capable of breaking underground stubbles and cutting off over-ground straws, and has the characteristics of being novel, reasonable and simple in structure, good in stubble-cutting and straw-breaking operation quality, small in ground-breaking amount, high in anti-blocking function, low in power consumption and reliable in use.

Description

technical field [0001] The invention belongs to agricultural machinery, and mainly relates to an operation unit which can be equipped on a no-tillage seeding machine and is used for stubble breaking, straw breaking and blocking prevention. Background technique [0002] In recent years, agricultural science and technology workers have seen the significant role and effect of conservation tillage systems and methods in soil and water conservation, environmental protection and agricultural production. In the implementation of conservation tillage, no-tillage seeding equipment is the basis and premise to realize the mechanization of conservation tillage. No-tillage planters are required to operate on fields where a large amount of crop straws and stubble are retained. Breaking stubble, cutting straws and avoiding operation blockages are necessary functions. However, due to insufficient structural design, the existing no-till planters have technical defects such as large power co...
