Embodiment Construction

[0016] The cutter shaft assembly of the rotary tiller includes a cutter shaft 1, a tiller seat 2, a rotary tiller 3 and a weed protection ring 4. The cutter shaft 1 is fixed with assembly discs 5 at intervals, and the circumferences of two adjacent assembly discs 5 are A plurality of cultivating knife seats 2 are welded between. The cultivating knife seat 2 is in the shape of a strip, and its cross section is "∩"; the cultivating knife seat 2 is arranged in a dislocation shape between the assembly disks 5 . A plurality of rotary cultivating knives 3 are welded on the cultivating knife seat 2, and the rotary cultivating knives 3 on the adjacent cultivating knife seats 2 between each assembly disc 5 are installed in a dislocation shape, and the rotary cultivating knives on the adjacent cultivating knife seats 2 3 are opposite to each other. Thereby reducing the resistance of the rotary tiller 3 into the soil, so that the soil is not compacted after rotary tillage; effectively i...

Abstract

The invention relates to a rotary tiller blade shaft assembly, and belongs to the technical field of agricultural machine components. The rotary tiller blade shaft assembly comprises a blade shaft, rotary blade bases, rotary blades and grass-preventing rings, wherein assembly discs are fixedly installed on the blade shaft at intervals, the rotary blade bases are welded between the circumferences of the assembly discs, rotary blades are welded to the rotary blade bases, and the grass-preventing rings are arranged at the two ends of the blade shaft respectively; corner blades and grass cutting blades are evenly distributed on the circumferences of the assembly discs close to the grass-preventing rings, the rotary blade bases of the rotary tiller blade shaft assembly are installed on the blade shaft in a staggered mode, and the rotary blades are oppositely installed on the adjacent rotary blade bases. Soil penetration resistance of the blades is small, soil does not harden after rotary tillage, and the rotary tillage effect is greatly improved. The rotary tiller blade shaft assembly is adaptable to rotary tillage operation on upland fields and paddy fields, and reduces cost of investment in agricultural machines by farmers. The rotary blades are pentagonal, abrasion can be effectively reduced, and the service life can be prolonged.

Description

technical field [0001] The invention relates to a cutter shaft assembly of a rotary tiller, which belongs to the technical field of agricultural machinery components. Background technique [0002] The rotary tiller is a kind of tillage machine developed in our country in recent years, and the rotary tiller shaft assembly is one of the most important parts of the rotary tiller. The knife shaft assembly of the rotary tiller is installed on the frame of the rotary tiller through the short shaft and the bearing seat, and the rotary tiller is installed on the knife shaft through the knife seat, and the knife seat is installed symmetrically in a cross shape on the knife shaft; it integrates Plowing and harrowing are integrated, and one rotary plowing operation on the farmland can achieve the working effect of plowing and harrowing several times with oxen. Due to the limitation of the structural form of the cutter shaft assembly, the current rotary tiller cannot be used in both dr...
