Abstract

The invention relates to a shredding cutter shaft with the air drafting effect, and belongs to crop straw processing devices. The shredding cutter shaft with the air drafting effect is composed of a bearing base, air drafting blades, a shredding cutter shaft body, a movable cutter base and a movable cutter, the bearing base is located at the two ends of the shredding cutter shaft body, the air drafting blades are evenly arranged outside the shredding cutter shaft body in a staggered mode, and the upper portion and the lower portion of the position, attached to the bearing base, of one end of the shredding cutter shaft body are provided with the movable cutter base and the movable cutter respectively. Through the technological improvement, the shredding cutter shaft has the advantages that crop straws, in particular to crop straws (rice straws) with the high shredding tenacity, are easily shredded; the movable equilibrium amount of the shredding cutter shaft is decreased, and the shredding cutter shaft is stable during high-speed rotation; vibration of a whole machine is reduced, and other components are easily protected.

Description

The chopping cutter shaft with air draught effect

Technical field

The invention belongs to the treating apparatus of crop straw, is a kind of chopping cutter shaft of crop straw secondary mincing and returning to the field specifically.

Background technology

The crop straw treating apparatus that market sale now and peasant use, the principle of its mincing and returning to the field is all the same.Utilize the kinetic energy of the chopping cutter shaft generation of High Rotation Speed, crop straw is picked up or crop straw is interrupted, be involved in frame housing, again through moving knife be arranged on the upper and lower blade row in frame housing cutting, impact, the long straw of crop is shredded, crop straw chopped, under the effect of air-flow and centrifugal force, is shed on the field after facility along frame inner walls.

Yet the crop straw that market sale now and peasant use cuts up and farmland returned machine, and does not also reach the object that the requirement of user institute will reach.Such as: the homogeneity question of shedding after crop straw chopping; After crop straw cutting, cut the problem that stubble is high, the end is uneven; The problems such as the easy clay stickweed of ground roll.

Summary of the invention

In order to address the above problem, the present invention aims to provide and a kind ofly by novel chopping rotor, designs, and can adsorb from the straw of combine chopping, carries out secondary chopping and sheds the straw secondary chopping of operation and shed the chopping cutter shaft with air draught effect on machine.

In order to achieve the above object, the present invention adopts following technical scheme:

The chopping cutter shaft with air draught effect, by bearing block, air draught blade, chopping cutter shaft, moving knife seat and moving knife, as technical characterictic of the present invention, bearing seat is in the two ends of chopping cutter shaft, the even distribution air draught blade straggly in outside of chopping cutter shaft, the position that bearing block is pressed close in one end of chopping cutter shaft is respectively equipped with moving knife seat and moving knife up and down.

As a further improvement on the present invention, the axle body that expose at chopping cutter shaft two ends is partly lying in the bearing block of widening at two ends; On the excircle of chopping cutter shaft, stagger and be symmetrically welded with the air draught blade of certain altitude, be interspersed between the space of cutting blade tool rest combination.

As a further improvement on the present invention, on the excircle of chopping cutter shaft, be welded with thin, the close moving knife seat differing that axial symmetry is arranged; Moving knife connects firmly on moving knife seat with bolt.

The present invention, through above-mentioned technological improvement, has reached following beneficial effect: be conducive to the chopping of crop straw, particularly shred the crop straw that toughness is very large (paddy stalk); The computing ballance correction that has reduced chopping cutter shaft, makes to shred cutter shaft more steady in High Rotation Speed; Reduce the vibrations of complete machine, to protecting other parts more helpful.

Accompanying drawing explanation

Fig. 1 is the chopping cutter shaft overall structure schematic diagram that the present invention has air draught effect;

Fig. 2 is chopping cutter shaft moving knife seat and the moving knife structural representation that the present invention has air draught effect.

Embodiment specifically

Below in conjunction with accompanying drawing, the present invention will be further described:

The chopping cutter shaft with air draught effect, by bearing block 1, air draught blade 2, chopping cutter shaft 3, moving knife seat 4 and moving knife 5, described bearing block 1 is positioned at the two ends of chopping cutter shaft 3, the even distribution air draught blade 2 straggly in outside of chopping cutter shaft 3, the position that bearing block 1 is pressed close in one end of chopping cutter shaft 3 is respectively equipped with moving knife seat 4 and moving knife 5 up and down.

The axle body that expose at described chopping cutter shaft 3 two ends is partly lying in the bearing block 1 of widening at two ends; On the excircle of chopping cutter shaft 3, stagger and be symmetrically welded with the air draught blade 2 of certain altitude, be interspersed between the space of cutting blade tool rest combination.

Described thin, the close moving knife seat 4 differing that on the excircle of chopping cutter shaft 3, are welded with axial symmetry arrangement; Moving knife 5 use bolts connect firmly on moving knife seat 4.

To rack-mounted chopping cutter shaft 3, done following design, accompanying drawing 1.The end face of two end axles bearing 1 is designed with seam; Making to shred the axle body that cutter shaft 3 two ends are exposed has packed in the bearing block 1 of widening, can prevent the winding of long straw and weeds, stop again entering of hard foreign material and silt particle, so just prevented the service life that the too early damage of bearings at both ends has improved again bearings at both ends.

On the excircle of chopping cutter shaft 3, stagger and be symmetrically welded with the air draught blade 2 of certain altitude; Making the cutting width of its whole covering moving knife, the object of air draught blade 2 is set, is the adsorption capacity that has increased the chopping cutter shaft generation of chopping cutter shaft 3 High Rotation Speeds, picks up the length stalk landing and carries out secondary chopping.

On the excircle of chopping cutter shaft 3, design is welded with thin, the close moving knife seat 4 differing that helical symmetry is arranged; The moving knife 5 every pair of light face are corresponding to be connected firmly on moving knife seat 4 with bolt.The former upper and lower fixedly blade row being fixed in frame is left and right putting the first edge on a knife or a pair of scissors; Upper and lower so every two left and right stationary knifes, just with the corresponding contact of light face that is arranged on two moving knife 5 on chopping each moving knife seat 4 on cutter shaft 3, the gap of every moving knife and stationary knife is very little; So just more be conducive to the chopping of crop straw, particularly shred the crop straw that toughness is very large (paddy stalk).It is that moving knife seat 4 is welded on the form on chopping cutter shaft 3 that helical symmetry is arranged.On the circumferencial direction of chopping cutter shaft 3, divide and have 4 Ge Xiangxian districts, in 1-3Xiang Xian district, (0-90 °, 180-270 °) is circumferentially symmetrically welded with thinner moving knife seat 4.In 2-4Xiang Xian district, (90-180 degree, 270-360 degree) is circumferentially symmetrically welded with closeer moving knife seat 4.The feature of design is the computing ballance correction that has reduced chopping cutter shaft 3 like this, makes to shred cutter shaft 3 more steady in High Rotation Speed; Reduce the vibrations of complete machine, to protecting other parts more helpful.
