Abstract
The invention relates to modification of a blade structure of a straw returning machine and provides a blade set of the straw returning machine. The blade set is low in power consumption, high in crushing power and convenient to repair. The blade set comprises a drive shaft and is structurally characterized in that three blade rests are disposed on the drive shaft and are connected with connectors of moving blades through bolts, fixed blades corresponding to the moving blades are disposed on the tool rests, and a cutting edge of each moving blade is arced.
Description
Technical field:
The present invention relates to a kind of improvement of straw returning machine knife blade.
Background technology:
The field-returning machine blade is the main working parts of straw cutting apparatus.The quality of blade has a significant impact work quality and the power consumption of field-returning machine.For adapting to the needs to the stalk of pulverizing all kinds of crops, recent year has been developed the blade of multiple pattern, roughly can be summarized as three classes:
1, L-type blade:
Blade shapes is similar to L shaped, because blade and stalk joint part are comparatively sharp, so this blade is comparatively thin, therefore, blade abrasion is fast, and intensity is low; When farm work, owing to the blade machining shape is that L-type makes its appearance beat native phenomenon, if run into the also easy maintenance difficult of damaged and blade of the hard thing such as stone.
2, hammer pawl formula blade:
Such blade exactly likes pawl with its shape and gains the name, and its intensity is large, wear-resistant and the life-span is long.This adaptability of tool is strong, the hard stalks such as the soft stalk of rice and wheat and corn, jowar, cotton all had good smashing capability, but the energy storage during owing to its rotation is large, be usually used on the big-and-middle-sized straw cutting apparatus, small-sized straw returning machine can not be used this blade owing to be short of power, so so that the use of this blade is promoted significant limitation is arranged.
3, straight knife type blade:
This straight knife type blade is formed by three straight knife sheets, horizontal blade and sleeve pipe assembly welding, and this blade adopts cut mode crushing straw; But, fit together because this blade is form by welding, thus after breaks down wherein replacement cost height and processing difficulties.
Summary of the invention:
The present invention is exactly for the problems referred to above, provides a kind of power consumption little, comminuted strong, and a kind of straw returning machine knife blade easy to maintenance.
For reaching above-mentioned purpose of the present invention, the present invention adopts following technical scheme, the present invention includes driving shaft, is provided with three knife rests on its structural feature driving shaft, links to each other with the connector of moving knife by bolt on the knife rest, is arranged on the tool rest corresponding to the stationary knife of moving knife; The blade of moving knife is set to arc.
Beneficial effect of the present invention:
1, power consumption is little, and is comminuted strong:
The blade of moving knife of the present invention is set to arc, thereby has increased the linear velocity of moving knife end, because the increase of linear velocity increases the kinetic energy of moving knife, and can cut off easily and pulverize various stalks; And because the effect of inertia and structure has reduced the consumption of power;
2, be easy to repair:
Moving knife of the present invention links to each other with knife rest by bolt, when single moving knife damages, moving knife all need not be changed, and only needs to change broken parts and gets final product, and novel being easy to of this use repaired thus.
Description of drawings:
Fig. 1 is structural representation of the present invention;
Fig. 2 is that the A of Fig. 1 is to view;
1 is that tool rest, 2 is that stationary knife, 3 is that blade, 4 is that moving knife, 5 is that connector, 6 is that bolt, 7 is that knife rest, 8 is driving shaft in the accompanying drawing.
Embodiment:
The present invention adopts following technical scheme, the present invention includes driving shaft 8, is provided with three knife rests 7 on its structural feature driving shaft 8, links to each other with the connector 5 of moving knife 4 by bolt 6 on the knife rest 7, is arranged on the tool rest 1 corresponding to the stationary knife 2 of moving knife 4; The blade 3 of moving knife 4 is set to arc.
Below in conjunction with description of drawings one-off process of the present invention:
During work, driving shaft 8 rotations are rotated with the moving knife 4 on the movable knife rack 7, by the blade 3 of moving knife 4 and cooperating of stationary knife 2, stalk are shredded;
During maintenance, only need the part that moving knife 4 damages is unloaded, simply change just passable.
Claims (1)
1. straw returning machine knife blade, comprise driving shaft (8), it is characterized in that being provided with on the driving shaft (8) three knife rests (7), knife rest (7) is upper to link to each other with the connector (5) of moving knife (4) by bolt (6), is arranged on the tool rest (1) corresponding to the stationary knife (2) of moving knife (4); The blade (3) of moving knife (4) is set to arc.
