Abstract
The invention discloses an anti-winding tool component of a tillage machine. The anti-winding tool component comprises a tool shaft, tool bases and blades, wherein the tool bases are fixedly connected to the tool shaft by virtue of arc welding edges; the blades are fixedly connected in the tool bases; the lower parts of the tool bases extend along the arc directions of the arc welding edges and are gradually reduced in width so as to form arc-shaped sharp corners; further improvements are as follows: the tool bases are distributed along the spiral lines of the outer walls of the tool shaft; the spiral lines for distributing the tool bases have helix angles of 5-15 degrees; one side, which is back onto arc welding edges, of each arc-shaped sharp corner is provided with a grass cutting edge; the central axes of blade mounting holes of the cutter base deviate from the center of the tool shaft for certain distances. The anti-winding tool component is capable of preventing grass and straws from being wound on the tool shaft, obviously reducing the manual cleaning workload and improving the working efficiency, and is small in tool shaft and good in working stability during use.
Description
Technical field
The present invention relates to a kind of harvesting and tillage machine toolbox.
Background technology
Along with the development of agricultural, harvesting and tillage machine is widely used in agricultural production.Existing harvesting and tillage machine toolbox comprises cutter shaft, tool rest, blade; Tool rest is fixedly connected on cutter shaft by circular arc seam limit, blade is fixedly connected in tool rest, easily occur hanging grass in this toolbox operation process, extension stalk makes cutter shaft twine grass, twines the situation of stalk, increase the power consumption of rotary cultivator attachment, reduce operation quality, machinery can be made time serious normally to work, in order to make, machinery is normal to be run, people need manual cleanup, thus cause the waste of human and material resources resource.
Summary of the invention
The present invention is directed to the deficiencies in the prior art, propose one and cutter shaft can be avoided to twine grass, twine stalk, significantly reduce labor cleaning's workload, the antiwind toolbox of the harvesting and tillage machine of increasing work efficiency.
The present invention is achieved through the following technical solutions technical goal.
The antiwind toolbox of harvesting and tillage machine, comprises cutter shaft, tool rest, blade; Tool rest is fixedly connected on cutter shaft by circular arc seam limit, and blade is fixedly connected in tool rest; Its improvements are: described tool rest bottom extends along circular arc direction, circular arc seam limit, and width diminishes gradually, form arc wedge angle.
Further improvement is: described tool rest is arranged along the helix of cutter shaft outer wall.
Further improvement is: the helical angle that layout is used for the helix of tool rest is 5 ~ 15 °.
Further improvement is: the opposing side of described arc wedge angle and circular arc seam limit is provided with chaffcutter sword.
Further improvement is: described tool rest blade mounting holes central axis and the certain distance of cutter shaft off-centring.
The present invention compared with prior art, has following good effect:
1 tool rest bottom is provided with arc wedge angle, during work the weeds at cutter shaft outer rim place and straw arcuately wedge angle to slide and away from cutter shaft center, thus make cutter shaft straw winding and straw, like this, operationally, rotary tillage consumed energy is little in the present invention, operation quality is high, prosthetic is often cleared up, and operating efficiency is high.
2. arc wedge angle is provided with chaffcutter sword, weeds and stalk not only can be made away from cutter shaft center, also can cut off weeds and stalk during work, stops cutter shaft to be wound around by weeds and stalk further, significantly improves operating efficiency.
3. blade mounting holes center and cutter shaft off-centring, add the arm of force of blade cut power, under equal torque condition, significantly reduces the cutting force of blade, improve the service life of blade.
4. tool rest is arranged along the helix of cutter shaft outer wall, make harvesting and tillage machine set of knives in rotary course, a cutter is only had to be in the state of putting forth effort in any time period, sheet in whole like this cutter group just can cut off root stubble and earth and fragmentation progressively, overcomes existing harvesting and tillage machine set of knives because of intermittent the operation severe impact produced and the defect of beating.
Accompanying drawing explanation
Fig. 1 is structural representation of the present invention.
Fig. 2 is the A-A cutaway view of Fig. 1.
Embodiment
Below with reference to the accompanying drawings and the invention will be further described in conjunction with the embodiments.
The cutter of harvesting and tillage machine shown in accompanying drawing group, comprises cutter shaft 1, tool rest 2, blade 4; Tool rest 2 is fixedly connected on cutter shaft 1 by circular arc seam limit 2.1, and blade 4 is fixedly connected in tool rest 2; Tool rest 2 bottom extends along circular arc direction, circular arc seam limit 2.1, and width diminishes gradually, forms arc wedge angle 2.2, and in the present embodiment, arc wedge angle 2.2 side opposing with circular arc seam limit 2.1 is provided with chaffcutter sword 2.3.
Tool rest 2 is arranged along the helix of cutter shaft 1 outer wall, arranges that the helical angle of the helix being used for tool rest 2 is 5 ~ 15 °, in the present embodiment, arranges that the helical angle of the helix being used for tool rest 2 is 7 °.
Tool rest 2 blade mounting holes central axis and the certain distance of cutter shaft 1 off-centring.
