Description
Technical field
The utility model is related to agricultural cutter field, more particularly, to a kind of straw-returning knife.
Background technology
In traditional agricultural production, the stalk of plant will be gathered in and clean out ground, then be recultivated.Now in order to improve soil
The fertility on ground, is intended to using the cultivation mode of straw-returning, it is not necessary to gather in stalk and directly crush in the ground, then cultivated.
Present straw-returning blade structure, including an assembly head and a cutter hub, the cutter hub is a strip shape dress, and the cutter hub
Body middle part has bending.It is existing be medium carbon steel or high-carbon steel forging form, structure is mostly above-mentioned three tulwar structures,
Because its wearability is poor, therefore quick abrasion, replacing often, both have impact on functioning efficiency in use, and consumption blade is more.Separately
Outward, with the abrasion of blade, rust at blade, resistance increase, machine power load down, fuel consumption increases, while by
Original design shape is lost in the abrasion of blade, it is impossible to which complete crushing straw, operation quality is deteriorated, influence later ploughing
Kind.
Utility model content
Problem to be solved in the utility model is to provide a kind of straw-returning knife.
In order to solve the above technical problems, the technical solution adopted in the utility model is：A kind of straw-returning knife, its feature exists
In：Including assembly head and cutter hub, the cutter hub is divided into arc cutter hub and bar shaped cutter hub, and the body middle part of the arc cutter hub has

Connect, the arc cutter hub is set to two groups, and two groups of arc cutter hubs are in symmetrical structure on bar shaped cutter hub.
Further, the corresponding central angle of bending in the middle part of the body of the arc cutter hub is 30 degree of -50 degree.
Further, in two groups of arc cutter hubs, every group of arc cutter hub could be arranged to one or more.
Further, the assembly head is provided with external screw thread.
Further, the two sides and bottom of the cutter hub are provided with enhancing reinforcement block.
Further, the enhancing reinforcing portion is a wear-resistant coating.
The utility model is had the advantage that with beneficial effect：A kind of straw-returning knife that this programme is provided is by assembling
Cutter hub is freely assembled on head, assembling is simple, easy to use, and assembly head is set to by improvement to assemble multigroup cutter hub, makes
Obtain blade and reduce abrasion, improve and cultivate efficiency.
