Abstract
The utility model relates to a flat hook -type rotary tillage tooth. The utility model provides a can reduce into the ground resistance, increase the flat hook -type rotary tillage tooth of the efficiency of ploughing. Flat hook -type rotary tillage tooth, including the handle of a knife, its characterized in that: be equipped with the arc blade at the handle of a knife front end, arc blade front end is circular -arcly, circular -arc blade front end is that the arbor center of using the handle of a knife bottom to connect is partly for radial circle as the centre of a circle, use arbor center to distance between the blade front end, interior thick outer thin T font blade is personally submitted for the crosscut to the blade, blade and handle of a knife integrated into one piece.
Description
Technical field
The utility model belong to agricultural or forestry wholely; The parts of general agricultural machinery or farm implements, part or field of accessories, especially relate to a kind of improvement of rotary tillage toothing.
Background technology
Rotary blade is a kind of being arranged on rotary tiller shaft for revolving the instrument on ground.Existing rotary blade blade thick and when using crosscut bury (as accompanying drawing 1), soil-entering resistance is large, causes blade stressed very large, easily fractures.Cause locomotive energy loss very large, affect locomotive work efficiency.
Summary of the invention
The utility model is exactly for the problems referred to above, provides a kind of and reduces into ground resistance, the flat hook-type rotary tillage tooth increasing efficiency of ploughing.
For realizing above-mentioned purpose of the present utility model, the utility model adopts following technical scheme, flat hook-type rotary tillage tooth, comprise handle of a knife, it is characterized in that: be provided with arc blade in handle of a knife front end, described arc blade front end is arc-shaped, and described arc-shaped blade front end is the cutter shaft center connected with handle of a knife bottom is the center of circle, with a part for the spacing of cutter shaft center to the blade front end circle that is radius, described blade is cross section is interior thick outer thin T-shaped blade; Described blade and handle of a knife one-body molded.
As a kind of preferred version, the outer edge of described blade and the tangent line angle of arc-shaped blade front end are between 25 degree to 40 degree.
As another kind of preferred version, the side that described T-shaped blade is thicker is trapezium structure; The both sides of trapezium structure are thinner, and centre is thicker, and so in use first wear and tear in both sides, and middle wearing and tearing are comparatively slow, formed pointed.
The beneficial effects of the utility model.
At grade, and the utility model blade is arc to the utility model entirety, a part for the circle that to be the cutter shaft center connected with handle of a knife lower end be in blade front end does for the center of circle, and such blade leading inside is inevitable pointed; First the tip formed with blade leading inside during use buries, and reduces resistance.In addition, arc-shaped blade front end described in the utility model be with handle of a knife center bottom be the center of circle, with a part for the handle of a knife bottom circle that is radius to blade front end, during use, when cutter shaft rotates and blade is buried carry out to revolve ground, blade front end keeps unified movement track, blade front end embedded depth is identical, can make to support to greatest extent inside blade outside blade, makes blade not frangibility.In addition, the utility model blade is cross section is interior thick outer thin T-shaped blade, and thicker one end is in the inner side of arc blade, this kind of structure makes antiwear property inside blade be far longer than outside, ensure that tip, blade front end can not be ground bald, solve the problem that blade front end polishes the rear soil-entering resistance increase occurred.
Accompanying drawing explanation
Fig. 1 is existing rotary blade structural representation.
Fig. 2 is the utility model structural representation.
Fig. 3 is A-A view in Fig. 2.
Fig. 4 is the utility model and cutter shaft connection diagram.
In figure, 1 be blade, 2 be handle of a knife, 3 for cutter shaft.
Embodiment
As in Figure 2-4, flat hook-type rotary tillage tooth, comprise handle of a knife 2, it is characterized in that: be provided with arc blade 1 in handle of a knife 2 front end, described arc blade 1 front end is arc-shaped, described arc-shaped blade 1 front end is cutter shaft 3 center connected with handle of a knife 2 bottom is the center of circle, with a part for the circle that is radius of the spacing of 1 end before cutter shaft 3 center to blade, described cutter shaft 3 center is the cutter shaft 3 tangent plane center of circle; Described blade 1 for cross section be interior thick outer thin T-shaped blade.
The outer edge of described blade 1 and the tangent line angle of arc-shaped blade front end are between 25 degree to 40 degree.
Embodiment:
Locomotive is equipped with common rotary blade to carry out working with revolving, and locomotive uses two gear speed to advance reluctantly; And the rotary tillage degree of depth is at about 15cm.
Locomotive is equipped with the utility model rotary tillage tooth to carry out working with revolving, and locomotive can be advanced by three gear speed, and the rotary tillage degree of depth is at about 25cm.
Use the utility model flat hook-type rotary tillage tooth to improve after tested and revolve ground efficiency more than 50%.
