Abstract
The utility model discloses a cutter blade for cutting stubbles and cultivating and preparing field installed on a cage style stubble cutter roller, which is composed of a cutter body, a cutting edge and installation holes. The cutter body forms a strip shape, and the side edge of the cutter body is provided with the cutting edge; the installation holes are positioned on both ends of the cutter body. The utility model has the advantages of simple structure, low cost, small working resistance, convenient and flexible installation and operation, etc.
Description
The utility model relates to a kind of agricultural stubble cleaner workpiece, particularly relates to a kind of blades for cutting stubbles and soil working that is installed on the squirrel-cage stubble cutter.
Operation rotor on existing stubble cleaner or the rotovator all combines with " L " type tulwar, complex structure not only, and the cost height, working resistance is also bigger.For overcoming the deficiency of prior art, we have invented a kind of squirrel-cage stubble cutter.Change because of essence has taken place its version, thus the requirement of this novel rotor of incompatibility of existing " L " type tulwar, demand urgently developing a kind of can associated novel blades for cutting stubbles and soil working.
The purpose of this utility model is exactly will provide a kind of can satisfy the blades for cutting stubbles and soil working that the new type squirrel-cage stubble cutter is installed and used requirement.
The purpose of this utility model is achieved in that this blade by blade, and blade and installing hole constitute, and blade is strip, and its blade is positioned at the side of strip blade, and mounting hole site is in the both ends of blade.The length of blade is: L=200～600mm, width is: B=40～80mm, thickness is: δ=4～10mm, sword face angle is θ=10～40 °.
Concrete structure of the present utility model is provided by following embodiment and accompanying drawing thereof:
Fig. 1: be a kind of overall structure schematic diagram of blades for cutting stubbles and soil working.
Describing concrete structure of the present utility model in detail below in conjunction with accompanying drawing forms and embodiment:
This blade is by blade 1, and blade 3 and installing hole 2 constitute.Its blade 1 can be the uiform section strip, also can be made into the strip of central protruding song.But side at blade 1 is shaped on blade 3, is rectilinear edge also can be convex camber line blade according to the blade shape.Blade 3 can one-sidedly be made on blade 1, but also dual-side is all made blade.The blade shape of blade 1 can be the single face side edge, also two-sided symmetrical middle cutter.Installing hole 2 is positioned at the both ends of blade 1.The length of blade 1 generally can be: and L=200～600mm (recommended parameter is: 355mm), and for adapting to wide cut operation, the longest L=2000mm that reaches of blade; The width of blade is: (recommended parameter is: 55mm), thickness is: (recommended parameter is: 7mm), sword face angle is θ=10～40 ° (recommended parameter is: 20 °) to δ=4～10mm to B=40～80mm.During manufacturing, adopt 65Mn steel or the close steel of performance, directly make the specification blank that the side has cutting edge, get final product through fracture, punching and thermal treatment again through rolling.Also can adopt material, specification all to conform to the band steel section bar of requirement, make by machining.
