Abstract
The utility model discloses a cutter for cutting crop straw, bamboo and wood, which comprises a cutter body (1) and a handle (2) connected with the cutter body (1). The cross section of the cutter body (1) is in a trapezoidal shape, and the cutter is mainly characterized in that the thickness of an upper bottom edge (1-1) is smaller than that of a lower bottom cutter back (1-3). The cutter has the advantages of steel material saving, convenience in cutter operation, labor saving and the like.
Description
Technical field
The utility model relates to a kind of cutter that cuts lumbering agricultural crop straw and bamboo, belongs to the agricultural equipment technology.
Background technology
The cutter that cuts lumbering agricultural crop straw and bamboo that the utility model is related, the reaping hook that mainly comprises harvesting paddy and wheat etc., gather in the chopper of Chinese sorghum, corn, millet and sugarcane etc. and in agrisilviculture, be used for chopper of cutting down in shrub, little trees and bamboo etc. or the like.
Existing described cutter, its cross section is consistent by the edge of a knife to the thickness of the knife back substantially.So the cutter of structure not only seems heavy, and the felling operation is hard, and tool also will grind away thicker metal material when its edge of a knife puts the first edge on a knife or a pair of scissors in its preparation process, and this is the consumption energy consumption worker not only, but also can cause the waste of metal material.
Summary of the invention
The utility model aim to provide a kind of can economical with materials consumption, the cutter of lumbering agricultural crop straw and bamboo is cut in the relative labour-saving of felling operation, to overcome the deficiency of prior art.
The utility model realizes that the technical scheme of its purpose is:
A kind of cutter that cuts lumbering agricultural crop straw and bamboo comprises cutter hub, with the handle that is connected with cutter hub; Its innovative point is that described cutter hub cross 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.
Can understand by above given technical scheme, the utility model since its edge of a knife thickness thinner relatively than knife back thickness, use material and can save, the minimizing edge of a knife put the first edge on a knife or a pair of scissors the time, cut cut down brisk relatively laborsaving, thereby realized the purpose of this utility model.
The edge of a knife thickness of described cutter hub, in 0.5～1.8mm scope, the knife back thickness of described cutter hub is in 2.5～3.5mm scope; The ridge of the described knife back is circular-arc.The utility model is not limited to described edge of a knife thickness and knife back thickness.And edge of a knife thickness of being advocated and knife back thickness can satisfy the specification requirement of the above cutter.And the ridge of the described knife back is circular-arc technical scheme, will bring tangible benifit for safe in utilization.
The utility model advocates that also described cutter hub is the bow body shape that the edge of a knife is inwardly arranged, perhaps cutter hub is the edge of a knife and the approaching flat that is arranged in parallel of the knife back.But be not limited to this.And the described described cutter that is bow body shape mainly is applicable to the reaping hook of harvesting paddy and wheat and mowing etc., and is the described cutter of flat, mainly is applicable to the chopper of felling bamboo and wood and sugarcane etc.
The utility model advocates that also when cutter hub was bow body shape, the edge of a knife was provided with the saw thorn.Described saw thorn has 5～8 in every 1cm length range.But be not limited to this.
The utility model also advocates, is positioned at the knife-edge part with handle link cutter hub, is provided with the V-arrangement recess.The positive effect of this technical scheme is, can avoid using in the cutter operating process in reality, and staff and cutting edge saw thorn come in contact, and hinder the hand accident and cause.
The utility model is also advocated, is positioned at the free-ended knife-edge part of cutter hub, has one not have the flat segments that saw stings; Be positioned at the V-arrangement recess of cutter hub and the junction of the edge of a knife, have one not have second flat segments that saw stings.Because the existence of described flat segments, not only can avoid edge of a knife free end and near the generation of problem of relatively easily hurting sb.'s feelings of handle place, enter cutting edge and cut in the scope of cutting down but also help gathering in crop, and convenient actually operate with cutter.
After technique scheme was implemented, the materials that the utility model had were economized, and operated light characteristics such as laborsaving with cutter, were conspicuous.
Description of drawings
Fig. 1 is the front view of a kind of embodiment of the utility model; Given among the figure is the reaping hook that a kind of cutter hub 1 is bow body shape; 1-9 shown in the 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 (amplify, Rotate 180 °) of cutter hub 1 shown in Figure 1; By this figure as seen, the cutter hub cross section is trapezoidal, and its upper base is edge of a knife 1-1, goes to the bottom to be knife back 1-3; And, be that equivalent continuity symmetry is amplified by the thickness of edge of a knife 1-1 to knife back 1-3.Certainly its thickness also can be asymmetric amplification.For example described trapezoidal transverse face, a waist in its two waist is with upper base and going to the bottom respectively and just intersects etc.
Fig. 3 is the front view of the another kind of embodiment of the utility model, and given among the figure is edge of a knife 1-1 and the approaching chopper that is arranged in parallel of knife back 1-3.
