Abstract
The invention discloses an anti-winding rotary tillage tool apron which comprises a front plate, a rear plate, a left side plate, a right side plate and a blade mounting hole, wherein the front plate is provided with a front plate tool shaft welding edge; the rear plate is provided with a rear plate tool shaft welding edge; the front plate tool shaft welding edge and the rear plate tool shaft welding edge are arc-shaped edges adhered to outer walls of a tool shaft; the lower part of the rear plate extends along the arc direction of the rear plate tool shaft welding edge, and is gradually reduced in width so as to form an arc-shaped sharp corner; further improvements are as follows: one side, which is opposite to the rear plate tool shaft welding edge, of the arc-shaped sharp corner is provided with a grass cutting edge; the front plate, the rear plate, the left side plate and the right side plate are formed by bending and welding a whole plate; the central axis of the blade mounting hole deviates from the center of the tool shaft for a certain distance. According to the anti-winding rotary tillage tool apron, the dead angle at the joint of the tool apron and the tool shaft can be eliminated, the energy consumption of a rotary tillage device is reduced, the operation quality is improved, the frequency of manually cleaning machines is reduced and the working efficiency is obviously improved.
Description
Technical field
The present invention relates to the tool rest a kind of agriculture rotary tillage machine being fixed rotary blade.
Background technology
At present, existing rotovator is all provided with the tool rest of fixing rotary blade, but the tool rest of existing fixing rotary blade exists following problem: tool rest and cutter shaft weld exist dead angle, easily occur hanging grass in 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 a kind of dead angle of eliminating tool rest and cutter shaft junction, reduce the energy consumption of rotary cultivator attachment, improve operation quality, reduce the antiwind rotary tillage cutter holder of labor cleaning's machinery number of times.
The present invention is achieved through the following technical solutions technical goal.
Antiwind rotary tillage cutter holder, comprises header board, rear plate, left plate, right plate, blade mounting holes; Described header board is provided with header board cutter shaft seam limit; Described rear plate is provided with rear plate cutter shaft seam limit; Described header board cutter shaft seam limit, rear plate cutter shaft seam limit are the arc-shaped edges fitted with cutter shaft outer wall; Its improvements are: described rear plate bottom extends along circular arc direction, rear plate cutter shaft seam limit, and width diminishes gradually, form arc wedge angle.
Further improvement is: the opposing side of described arc wedge angle and rear plate cutter shaft seam limit is provided with chaffcutter sword.
Further improvement is: described header board, rear plate, left plate, right plate are a whole plate, through bending, are welded.
Further improvement is: described 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. after, the bottom of plate 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, eliminate the dead angle that tool rest and cutter shaft weld exist, what can solve the existence of prior art tool rest makes rotary cultivator attachment energy consumption large, operation quality is poor, machinery needs frequent labor cleaning, the defect wasted time and energy.
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. header board, rear plate, left plate, right plate are an entirety, form tool rest, significantly improve the intensity of whole tool rest after bending, welding.
4. 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.

Embodiment
Below with reference to the accompanying drawings and the invention will be further described in conjunction with the embodiments.
Antiwind rotary tillage cutter holder shown in the drawings, comprises header board 1, rear plate 2, left plate 3, right plate 4, blade mounting holes 5; Header board 1 is provided with header board cutter shaft seam limit 1.2; Rear plate 2 is provided with rear plate cutter shaft seam limit 2.3; Header board cutter shaft seam limit 1.2, rear plate cutter shaft seam limit 2.3 are the arc-shaped edges fitted with cutter shaft outer wall; Rear plate 2 bottom extends along circular arc direction, rear plate cutter shaft seam limit 2.3, and width diminishes gradually, forms arc wedge angle 2.2.
In the present embodiment, arc wedge angle 2.2 side opposing with rear plate cutter shaft seam limit 2.3 is provided with chaffcutter sword 2.4, weeds and stalk not only can be made when such the present invention works away from cutter shaft center, also can cut off weeds and stalk, play and better prevent cutter shaft by weeds and stalk winding effect.
For improving the intensity of whole tool rest, in the present embodiment, header board 1, rear plate 2, left plate 3, right plate 4 are a whole plate, through bending, are welded.
In the present embodiment, blade mounting holes 5 central axis and the certain distance of cutter shaft 6 off-centring, like this, add the arm of force of blade cut power, under equal torque condition, significantly reduce the cutting force of blade, improve the service life of blade.
