Abstract
The invention relates to a ditching device, comprising a circular disc, a cutter shaft and cutter teeth, wherein, the circular disc is fixed on the cutter shaft and is equipped with locating steps protruding the surface of the circular disc; the locating steps are enclosed into a boss which is concentric with the circular disc; the cutter teeth are arranged on the circular disc; and the locating steps are used for fixing and limiting the cutter teeth. The ditching device has the advantages that while a seeding machine works, the circular disc of the ditching device rotates, and the cutter teeth cut into soil alternately; and the pressure borne by the circular disc is completely concentrated on the tip part of the cutter teeth, thus more powerfully and conveniently cutting soil and being especially suitable for no-tillage ditching on hard soil.
Description
Technical field
The present invention relates to a kind of parts of agriculture combined machine, be specifically related to a kind of plough.
Background technology
The degeneration and the desertification problem on China arid and semi-arid grassland are very serious, the ecological environment problem that having become to take the necessary measures solves, with the grassland, Tibet is example, existing 3.64 hundred million mu of whole district degeneration grassland, account for and can utilize 42% of area, in recent years, doing a lot of work aspect the high and cold meadow of improvement, the after-culture herbage in the Tibet region, but tempo is slower, and reason is to lack the suitable careless machinery of broadcasting.Because the soil layer on degeneration grassland is very thin, so be not suitable for adopting traditional ploughing mode to sow, publication number is that the Chinese invention patent of CN 2781735Y discloses a kind of seed-sowing machine that adopts the rotary tillage mode to ditch.This seed-sowing machine mainly is made up of banded rotary tillage ditching device, fertilizer dispenser, a kind bed treating apparatus, suppression of soil device four major parts.This seed-sowing machine can not well adapt to the natural environment on grassland, Tibet in production operation.Grassland, Tibet condition uniqueness, the meadow development degree is very low, and soil layer is thin but very hard, also has a large amount of stones in the face of land and the soil, uses the trench digging device of above-mentioned seed-sowing machine can't leave enough dark groove, causes the herbage survival rate of sowing lower, influences seeding operation.
Summary of the invention
The technical problem to be solved in the present invention provides a kind of defective that overcomes traditional product, and a kind of plough that can realize no-tillage trench digging on hard soil is provided.
Plough of the present invention comprises circular disk body, cutter axis and cutter tooth, circular disk body is fixed on the cutter axis, the positioning step that comprises the herniated disk surface on the circular disk body, positioning step surrounds the boss with the circular disk body concentric, described cutter tooth is fixedly installed on the described circular disk body, and described positioning step carries out fixed limit to described cutter tooth.
Plough of the present invention, wherein, described cutter tooth comprises working portion and fixedlys connected part, described working portion is structure as a whole with the described part of fixedlying connected,
Plough of the present invention, wherein, the drift angle a of described working portion is 60 degree.
Plough of the present invention, wherein, the dual-side of described working portion has sword.
Plough of the present invention, wherein, the positioning step of described each circular disk body is ten, and described ten positioning steps surround the regualr decagon boss with the circular disk body concentric, and described ten described cutters tooth are installed on described each circular disk body.
Plough of the present invention, wherein, the material selection high-quality manganese alloy steel of cutter tooth.
Plough of the present invention, wherein, the working portion plating hard chromium on surface of cutter tooth.
Plough of the present invention, wherein, cutter tooth thermal treatment is surface hardening, and the surface is wear-resisting firmly, and core is tough, shock resistance.
The advantage of plough of the present invention is: when carrying out the sower operation, the circular disk body of plough is rotated, cutter tooth is cut in the soil in turn, the pressure that circular disk body is born concentrates entirely on the point of a knife part of cutter tooth, it is just more strong to cut soil, fast, be particularly suitable for realizing on the hard soil no-tillage trench digging.
Plough of the present invention when some cutters tooth wear and tear or run into the obstacle damage, can easily be changed.
Description of drawings
Fig. 1 is the front view of plough of the present invention;
Fig. 2 is the right view of Fig. 1;
Fig. 3 is the front view of cutter tooth among Fig. 1.
Embodiment
As shown in Figure 1 and Figure 2, plough of the present invention comprises cutter axis 10, circular disk body 22 and cutter tooth 23, and wherein, three circular disk body 22 are fixedly installed on the cutter axis 10 by centre bore.Circular disk body 22 also can be one or two or more.
24, ten positioning steps 24 of positioning step that comprise ten herniated disk surfaces on each circular disk body 22 surround the regualr decagon boss 25 with the circular disk body concentric.
Ten cutters tooth 23 are installed on the circular disk body 22 by bolt respectively.Ten positioning steps 24 are respectively in order to carry out fixed limit to ten cutters tooth 23.
In conjunction with shown in Figure 3, cutter tooth 23 comprises working portion 231 and fixedlys connected part 232.Working portion 231 with fixedly connected part 232 and be structure as a whole.Working portion 231 roughly is equilateral triangle, and drift angle a is 60 degree, and for being convenient to bury, dual-side has sword.Have two screws on the coupling part 232, be convenient to fixedly connected with circular disk body 22.
In order to improve the service life of cutter tooth 23, the material selection high-quality manganese alloy steel of cutter tooth 23 is in order to strengthen wearability, working portion 231 plating hard chromium on surface of cutter tooth 23.Surface hardening is adopted in cutter tooth 23 thermal treatments, and the surface is hard, core is tough, not only wear-resisting but also shock resistance.
When using plough of the present invention to carry out the sower operation, be installed on sower or broadcast on the frame of careless machine the cutter axis 10 that one or more circular disk body 22 are installed is rotating, its mounting means can adopt but not limit axle commonly used-bearing mounting means, the bearing block that promptly fixedly has bearing on frame, cutter axis 10 are installed on the frame by bearing block.When using plough of the present invention to carry out the sower operation, cutter axis 10 drives the circular disk body 22 that is fixed on the cutter axis 10 and rotates, and ten cutters tooth 23 are cut in the soil in turn, leaves the groove of del.
Some cutters tooth 23 wearing and tearing or when running into obstacle and damaging can easily be changed.
The above embodiment only is that preferred implementation of the present invention is described; be not that scope of the present invention is limited; design under the prerequisite of spirit not breaking away from the present invention; various distortion and improvement that those of ordinary skills make technical scheme of the present invention all should fall in the definite protection domain of claims of the present invention.
