Abstract

The present invention relates to a crushing processing device which is used for plant stalk in the industries of papermaking, clean energy, etc. Specifically the invention relates to a combined dead knife straw crusher. The device comprises at least one rotatable knife roll which is arranged with a plurality of knife discs. The circumferences of knife discs are uniformly installed with a plurality of fly knife blades. The edges of two sides of each fly knife blade are provided with transverse cutting edges. The radial outer margin of each fly knife blade is provided with a longitudinal cutting edge. The side part of knife roll is fixed with a longitudinal dead knife in longitudinal direction. The rotation track of longitudinal cutting edge of fly knife blade is next to the longitudinal edge of longitudinal dead knife so that the longitudinal cutting edge and the longitudinal dead knife can execute relative shearing movement. The side of knife roll next to the longitudinal is also fixedly installed with a plurality of transverse dead knifes which are transversely installed and are positioned in the clearance between the adjacent knife discs, so that the transverse cutting edges of fly knife blades and the transverse dead knifes can execute relative shearing movement. The crushing processing device of the invention greatly increases the homogeneity of crushing and simultaneously has the advantages of smooth crashing process, little impact vibration and high reliability.

Description

Straw crushing device with combined bed knife
Technical field
The present invention relates to a kind of broken process equipment of the plant stem that uses in industries such as papermaking, clean energy resource, specifically is a kind of combined bed-knife straw crusher.
Background technology
Existing straw crushing device commonly used generally comprises a pair of rotor that is installed in the crusher chamber, each rotor upper edge axially spaced-apart a plurality of cutterheads of arranging, a plurality of roll bars evenly are set on the circumference of cutterhead, cutterhead on two rotors is interlaced, carry out the relative shear campaign by the cutterhead on two rotors in the course of the work, the side edge that utilizes roll bar is with the straw shearing-crushing.In this structure, the shear surface of roll bar is vertical with the rotor rotor shaft direction, therefore is merely able to the straw of vertical feeding is produced shear effect preferably, then can't effectively shear the straw of horizontal feeding, influence shear effect, reduced the uniformity of shearing; In addition, when the straw of feeding is mixed and disorderly, also cause the clamping stagnation between cutterhead easily, influence normally carrying out of broken processing.
Summary of the invention
Technical problem to be solved by this invention is, a kind of simple in structure, crushing effect good, shattering process is smooth, reliability is high combined bed-knife straw crusher is provided.
Straw crushing device with combined bed knife of the present invention includes at least one the rotatable rotor that is positioned at crusher chamber, rotor upper edge axially spaced-apart be placed with a plurality of cutterheads, on the circumference of cutterhead, evenly be provided with a plurality of roll bars; The both sides of the edge of roll bar have transverse blade, and the radially outer edge of roll bar has vertical blade; Be fixed with a vertical longitudinally bed plate in the rotor side, the rotational trajectory of vertical blade of roll bar makes vertical blade carry out the relative shear campaign with vertical bed plate near the longitudinal edge of vertical bed plate; In the side of rotor near vertical bed plate, also fixed in position has a plurality of horizontal bed plaves that are horizontally arranged with, and in the space of horizontal bed plate between adjacent cutterhead, makes the transverse blade of roll bar carry out the relative shear campaign with horizontal bed plate.
Described rotor can have two, and two rotors are arranged side by side, vertical bed plate between two rotors, vertical bed plate both sides be provided with two groups respectively with two corresponding horizontal bed plaves of rotor.
The circumferential position that roll bar distributes on each cutterhead and the roll bar on the adjacent cutterhead certain angle that staggers makes that the roll bar on each cutterhead is sheared with bed plate successively, with the minimizing shock loading.
The present invention is provided with the bed plate and the roll bar with longitudinal and transverse blade with matching of longitudinal and transverse direction, make the straw that feeds no matter how can both be sheared preferably by direction, thereby improved broken uniformity greatly, simultaneously its shattering process smoothness, impact shock is little, reliability is high.

Fig. 2 is two rotors of the embodiment of the invention and the planar structure schematic diagram of bed plate;
Fig. 3 is the distribution schematic diagram of roll bar on the different cutterheads of the embodiment of the invention.
Embodiment
As shown in Figure 1 and Figure 2, embodiments of the invention have two rotors that are arranged side by side 1, be placed with a plurality of cutterheads 2 rotor upper edge axially spaced-apart, on the circumference of cutterhead, evenly be provided with a plurality of roll bars 3, the both sides of the edge of roll bar have transverse blade 31, and the radially outer edge of roll bar has vertical blade 32; A vertical longitudinally bed plate 4 is set between two rotors, and vertical bed plate both sides are provided with two groups and extend transversely into the horizontal bed plate 5 in the space between the cutterhead.In the course of work, the transverse blade 31 of roll bar cooperates with horizontal bed plate 5, can effectively shear the straw of vertical feeding, and vertical blade 32 of roll bar cooperates with vertical bed plate 4, can effectively shear the straw of horizontal feeding.
As shown in Figure 3, the circumferential position that roll bar 3 distributes on each cutterhead 2 and the roll bar 3 on the adjacent cutterhead certain angle that staggers, thus on the rotor total length, form the edge of a knife helix of some interruptions, to reduce the shock loading of cutting off generation when broken.
