Abstract
The invention discloses a cutter cutting crops straws and bamboo & wood; the cutter comprises a cutter body (1) and a handle (2) connected with the cutter body (1); the cutter body (1) has a trapezoid cross section, and the thickness of the upper base cutter edge (1-1) is smaller than the thickness of the lower base cutter back (1-3). The cutter can save steel, is convenient in operation, and is laborsaving.
Description
Technical field
The present invention relates to a kind of cutter cutting lumbering agricultural crop straw and bamboo, belong to agricultural equipment technology.
Background technology
The involved in the present invention cutter cutting lumbering agricultural crop straw and bamboo, mainly includes the reaping hook of harvesting paddy and wheat etc., the chopper of harvesting Sorghum vulgare Pers., Semen Maydis, Semen setariae and Caulis Sacchari sinensis etc., and is used for chopper cutting down shrub, little trees and bamboo etc. etc. in agrisilviculture.
Existing described cutter, its transverse section is substantially coincident by the thickness of the edge of a knife to the knife back.The cutter of such structure, not only seems heavy, and felling operation is hard, and has in its preparation process, also when its edge of a knife puts the first edge on a knife or a pair of scissors, to grind away the metal material that comparison is thick, this work consuming that not only consumes energy, but also can cause the waste of metal material.
Summary of the invention
It is desirable to provide one can save material consumption, felling operates relative labour-saving and cuts the cutter of lumbering agricultural crop straw and bamboo, to overcome the deficiency of prior art.
The present invention realizes the technical scheme of its purpose:
A kind of cutter cutting lumbering agricultural crop straw and bamboo, including cutter hub, and the handle being connected with cutter hub；Its innovative point is in that, described cutter hub transverse section is trapezoidal, and the thickness of its upper base edge of a knife, less than the thickness of the knife back of going to the bottom.
By technical scheme given above it is understood that due to the fact that its knife edge thickness is more relatively thin than knife back thickness, and can save with material, reduce the edge of a knife and put the first edge on a knife or a pair of scissors the time, cut cut down relatively brisk laborsaving, it is achieved thereby that the purpose of the present invention.
The knife edge thickness of described cutter hub, within the scope of 0.5～1.8mm, the knife back thickness of described cutter hub, within the scope of 2.5～3.5mm；The ridge of the described knife back is arc-shaped.The present invention is not limited to described knife edge thickness and knife back thickness.And the knife edge thickness advocated and knife back thickness, it is possible to meet the technology requirement of the above cutter.And the ridge of the described knife back is arc-shaped technical scheme, for using safety will bring obvious benifit.
The present invention also advocates, described cutter hub is the bow body shape that the edge of a knife is inwardly arranged, or cutter hub is the edge of a knife flat that is arranged in parallel close with the knife back.But it is not limited to this.And the described described cutter in bow body shape, it is primarily adapted for use in the reaping hook of harvesting paddy and wheat and mowing etc., and in the described cutter of flat, is primarily adapted for use in the chopper of felling bamboo and wood and Caulis Sacchari sinensis etc..
The present invention also advocates, when cutter hub is in bow body shape, the edge of a knife is provided with saw thorn.Described saw thorn has 5～8 in every 1cm length range.But it is not limited to this.
The present invention also advocates, is positioned at and the knife-edge part of handle attachment end cutter hub, is provided with V-arrangement recess.The positive effect of this technical scheme is in that, it is possible to avoid in reality cutter operating process, and staff comes in contact with cutting edge saw thorn, and causes and hinder hands accident.
The present invention also advocates, is positioned at the knife-edge part of cutter hub free end, has a flat segments stung without saw；It is positioned at the V-arrangement recess of cutter hub and the junction of the edge of a knife, has second flat segments stung without saw.Due to the existence of described flat segments, not only can avoid edge of a knife free end and the generation of problem of relatively easily hurting sb.'s feelings close to handle place, but also be conducive to harvesting crop to enter cutting edge and cut in the scope of cutting down, and convenient reality cutter operates.
After technique scheme is carried out, the materials that the present invention has relatively are economized, and operate the features such as Portable power saving with cutter, are apparent from.
Accompanying drawing explanation
Fig. 1 is the front view of a kind of detailed description of the invention of the present invention；Given by figure is a kind of cutter hub 1 reaping hook in bow body shape；1-9 shown in figure is the limit line that the edge of a knife puts the first edge on a knife or a pair of scissors；
Fig. 2 is the schematic cross-sectional view (amplifying, rotate 180 °) of cutter hub 1 shown in Fig. 1；It may be seen that cutter hub transverse section is trapezoidal, its upper base is edge of a knife 1-1, goes to the bottom as knife back 1-3；And by the thickness of edge of a knife 1-1 to knife back 1-3, be that equivalent continuity symmetry is amplified.Certainly its thickness can also be asymmetric amplification.Such as described trapezoidal transverse face, a waist in its two waist, respectively with upper base and go to the bottom in just intersecting；
Fig. 3 is the front view of another kind detailed description of the invention of the present invention, and given by figure is the close chopper being arranged in parallel of edge of a knife 1-1 and knife back 1-3.
Detailed description of the invention
Hereinafter compareing accompanying drawing, by the description of detailed description of the invention, the invention will be further described:
One of detailed description of the invention, as shown in accompanying drawing 1,2:
Cut a kind of cutter cutting down agricultural crop straw and bamboo wood, including cutter hub 1, and the handle 2 being connected with cutter hub 1；The edge of a knife 1-1 of cutter hub 1, is provided with the saw thorn 1-2 of layout continuously, and described cutter hub 1 transverse section is trapezoidal, and the thickness of its upper base edge of a knife 1-1, less than the thickness of the knife back 1-3 that goes to the bottom.And the edge of a knife 1-1 thickness of described cutter hub 1, within the scope of 0.5～1.8mm, the thickness of the knife back 1-3 of described cutter hub 1, within the scope of 2.5～3.5mm；The ridge of described knife back 1-3 is arc-shaped.The bow body shape that described cutter hub 1 is inwardly arranged in edge of a knife 1-1, the saw thorn 1-2 set by edge of a knife 1-1, is 5～8 in every 1cm length range.It is positioned at the edge of a knife 1-1 place with handle 2 link cutter hub 1, is provided with V-arrangement recess 1-4.It is positioned at the edge of a knife 1-1 place of cutter hub 1 free end, has one to sting the flat segments 1-5 of 1-2 without saw；It is positioned at the junction of the V-arrangement recess 1-4 and edge of a knife 1-1 of cutter hub 1, has one to sting the second flat segments 1-6 of 1-2 without saw.Described by this embodiment is reaping hook.
