Description

A kind of pulley type straw granule-forming machine

Technical field

The utility model belongs to a kind of farm equipment, more particularly to specifically related to a kind of pulley type straw granulating dress Put.

Background technology

Straw granulating technology is one kind of biomass utilization technologies.In the market stalk forming technology is mainly with ring Based on mould, flat-die grain forming, the mold use life-span is low, and the requirement to material is higher, needs to enter stalk mostly before shaping Row comminution pretreatment, and need to be heated material in forming process, energy consumption is big, complex process, and occupation area of equipment is big, raw Bad environments are produced, dust pollution is more serious, and production efficiency is relatively low.

Such as：Number of patent application 201020519186.9, mandate publication number CN201841002U provide a kind of bimodulus pair Pressure mutually squeezes straw granulator, and the equipment is difficult to realize carrying out extrusion molding, and the thing larger to particle diameter while shredding material Expect easy jam.

The content of the invention

Based on the shortcoming of existing these straw granulating technology and equipments, in order to overcome it not enough, one has now been invented Plant new production efficiency height, the low straw granule-forming machine of energy consumption and forming method.

The technical solution of the utility model is：

A kind of pulley type straw granule-forming machine, includes the hollow roller drum of a pair of intermeshings rotation, each hollow roll Double wedge and groove are evenly arranged with cylinder, the head of groove is provided with the horn mouth communicated with circular hole, is provided with the middle part of hollow roller drum The discharging chamber communicated with circular hole；The double wedge of hollow roller drum is embedded just below in the groove of another hollow roller drum, while another hollow roll The double wedge of cylinder is also embedded just below in the groove of a hollow roller drum, and both install in interlaced arrangement, and adjacent double wedge side wall It is provided with gap and recess sidewall between, adjacent double wedge, double wedge both sides side wall seamed edge are blade-like.

The forming principle of the technical scheme：Using the characteristic of stalk compressible formation compactness solid under high pressure entering The production and processing of row stalk particle.The stalk of chopping is clamp-oned in narrow and small cavity volume, as stalk is continuously passively clamp-oned, The pressure that stalk bears in fixed cavity volume is increasing, and local pressure under high pressure, sends out stalk up to more than 100MPa Raw mutually to slide, space each other is reduced, and which part can produce plastic deformation, between stalk it is mutually nested reach it is certain Adhesion, and along with the cementation of emplastic in stalk, makes mutually to be tangled between stalk, is tightly combined, loose, pressure Make the effigurate solid particle of tool.

The utility model has the advantage of：The technical matters is very simple, without the need for being crushed to stalk, being heated before shaping Deng pretreatment measure, directly rod-shpaed particle can be processed into in field through the stalk for drying naturally.And grain forming is imitated Really good, according to the difference of stalk material, grain density is up to 0.6～0.8t/m³；Production efficiency is high, and energy consumption is low.The technology is adapted to Property it is quite varied, can be used in combination with stalk pickup machinery, directly stalk is processed into into particle while stalk is picked up, can be with Greatly save intermediate transition time and the cost of stalk；Also apply be applicable to fix in factory building, carry out the production in enormous quantities of particle.

Specific embodiment

The utility model is described further below in conjunction with the accompanying drawings.

In the utility model, the noun of locality for using as " upper and lower, left and right " typically refer to it is upper shown in refer to the attached drawing, Under, it is left, it is right；" inside and outside " is referred to relative in each part profile of itself, outward.

Referring to shown in Fig. 1, Fig. 2, the core texture of the utility model is the hollow roller drum that a pair of intermeshings are rotated.Roller A is rotated clockwise with certain rotating speed, and roller B is rotated counterclockwise with identical rotating speed, and the rotary state of roller is similar to gear Gear motion.Double wedge and groove are machined with the circumference barrel of roller A and roller B, double wedge and groove are staggered, groove Some circular holes are uniformly machined with circumference, the porch of circular hole is horn mouth.When two rollers are installed, the double wedge of roller A is just In the groove of embedded roller B, while the double wedge of roller B is also embedded just below in the groove of roller A, both interlaced arrangement peaces Dress, and ensure between double wedge side wall and recess sidewall with certain gap.

Simultaneously the centre distance of roller must be fixed, to guarantee that each double wedge crown will be embedded in the horn mouth of circular hole necessarily Depth, and roller will not interfere with when mutually rotating.To feed from the centre position on two roller top through the stalk for drying naturally Enter, when roller is mutually rotated, double wedge is brought into together rotation by material, and the both sides side wall seamed edge of two roller double wedges is similar to scissors Cutting edge, will bring material cut-out herein into, by double wedge crown press-in circular hole horn mouth while material is cut off.So follow Ring, go round and begin again, material is cumulative in horn mouth, and packing gradually increases, discharge finally by circular hole, generate bar-shaped Particle.

The implementation case is further elaborated referring to Fig. 3.The forming process of stalk：Roller A is rotated clockwise, Roller B is rotated counterclockwise；With the rotation of roller, the crown 21 on crown 11 and roller B on roller A brings stalk downwards into Motion, while stalk herein is tentatively extruded, some tiny stalk particles can be forced in horn mouth 14, tentatively extruded Larger longer stalk continue to move downward, roller A and roller B cutting edges 12,22 also operate downwards, when cutting edge 12,22 start phase During friendship, the cutting edge of now relative motion similar to the scissors for shearing material, by the straw cutting with edge contacts；Stalk quilt While cut-out, crown 11,21 is clamp-oned in roller horn mouth 13 and roller horn mouth 23 on roller, continuous with roller Rotate, stalk is constantly cut off, is constantly squeezed in roller horn mouth, and the stalk in horn mouth is cumulative, increasingly Closely knit, the pressure that stalk bears is also increasing, and when pressure increases to a certain extent, the stalk block being extruded can slowly enter roller In the circular hole of cylinder.Circular hole has a segment distance, and the length of the segment distance is the several times of Circularhole diameter.The section is referred to as stalk guarantor's type Section, in guarantor's type section, stalk block is further compressed, while the stalk block and circular hole wall generation for bearing high pressure is prolonged relative Substantial amounts of heat can be produced after slip, the heat raises the temperature of stalk block itself and circular hole wall.At high temperature, which part Stalk block can produce emplastic in plastic deformation, and stalk block and can produce certain cementation, make mutually to be twined between stalk Knot, combination are more tight, while the circular hole wall being heated can make stalk block surface local charing occur so as to be hardened not loose. Finally, closely have figurate stalk block to extrude from circular hole end, form circular shaping bar 15.

The utility model is not limited to above-mentioned embodiment, using identical or approximate with the above-mentioned case study on implementation of the utility model Structure, and obtain other structures design, within protection domain of the present utility model.Such as：The profile of change double wedge For other concaveconvex shapes, circular discharge opening is changed to into square or other shapes etc., belongs to protection domain of the present utility model.
