Specific embodiment

The utility model is described in detail below with reference to attached drawing and in conjunction with the embodiments.It should be noted that not conflicting In the case where, the feature in the embodiments of the present invention and embodiment can be combined with each other.For sake of convenience, hereinafter such as There is "upper", "lower", "left", "right" printed words, only indicates consistent with the upper and lower, left and right direction of attached drawing itself, not to structure Play restriction effect.

As shown in Figure 1, the stalk crasher provided by the embodiment includes rack 1, pulverizer ontology 2, pulverizing device frame 3, conveyer belt 4, crushing driving motor 5 and feed drive motor 6.

The rack 1 is frame structure, and is obliquely installed.Its high one end is equipped with the pulverizer ontology 2.Pulverizer machine Frame 3 is set to the lower section of 2 discharge port 21 of pulverizer ontology.The conveyer belt 4 tilts in the rack 1 along the rack 1 Setting, one end is close to ground, the other end up to pulverizer ontology feed inlet 22.

It is interior with crushing chamber 23 for the pulverizer ontology 2, and top is covered with pulverizer upper cover 24, is enclosed with below Sieve 25.Multiple circumferentially spaced hammer leaves 26 are contained in the crushing chamber 23, the crushing driving motor 5 is for driving Dynamic hammer leaf 26 rotates.

Conveyer belt 4 conveys stalk to the feed inlet 22 of pulverizer ontology 2, and the direction of rotation of hammer leaf 26 is the counterclockwise of Fig. 1, That is, 26 direction of rotation of hammer leaf is mutually cut with 4 conveying direction of conveyer belt.Mutually it is defeated to refer to that the direction of rotation of hammer leaf 26 is directed toward for incision Send the conveying direction of band 4.As shown in Figure 1 and Figure 2, the hammer leaf 26 is extended vertically from its direction of rotation, the sawtooth of the hammer leaf 26 Set on the both ends of its extending direction.

It is by four angles of hammer leaf 26 chopping material that stalk, which crushes, and in addition hammer leaf end sawtooth also has the effect of blank, will saw Tooth is set to both ends, so that blank effect doubles, and will not bridging.If there is material on sawtooth, can also be got rid of because of centrifugal force, so At this moment a kind of pulverizer for being suitable for crushing two kinds of dry and wet material, strong applicability.In addition, end face is that there are one weights for broached-tooth design The effect wanted is exactly most edge wedge angle by after rounding, and sawtooth thereafter will undertake main particle effect, so that this hammer leaf has for a long time There is preferable particle effect.The hammer leaf moderate cost of this structure, good economy performance.

As shown in Figure 1, Figure 3,2 outside of the pulverizer ontology is circumferentially arranged at intervals with multiple for fixed grit 25 Sieve press fastening device 27.The sieve press fastening device 27 includes the screen baffle 271 for being set to 25 side of sieve, is connected to sieve 25 The compression bar 272 of the other side and the mounting base 273 being connect with pulverizing device frame 3, the mounting base 273 be L-type structure, one end with Pulverizing device frame 3 is detachably connected by bolt, and the other end is equipped with adjusting rod 274 and is connected to one of compression bar 272 far from sieve 25 Side.

The adjusting rod 274 include the screw rod 2741 being threadedly coupled with the mounting base 273 and be set to the mounting base 273 Outside with and screw rod 2741 cooperate nut 2742,2741 end of screw rod is connected to the compression bar 272.In the present embodiment In, the screw rod 2741 welds together with compression bar 272, when being dismantled to sieve 25, the mounting base 273 that need to only come loose and pulverizer machine The bolt of frame 3 can be realized.

The quantity of the mounting base 273 is two, is respectively arranged on 25 both ends of sieve, the quantity of the screen baffle 271 is It is two, corresponding with 273 position of mounting base.

Multiple sieve press fastening devices 27 are used for 25 fixation of sieve.When sieve 25 is installed, sieve 25 is attached to sieve Baffle 271, then compression bar 272 and mounting base 273 are loaded onto, mounting base 273 is fixed by bolts on pulverizing device frame 3.Use spiral shell The spiral rotating adjustment length of bar 2741 uses 2742 tie down screw 2741 of nut to hold out against compression bar 272 afterwards.At this point, sieve 25 is just It is completely fixed, does not need to tear pulverizer upper cover 24 open.When disassembly or replacement sieve 25, mounting base 273 and pulverizer machine need to be only removed The installation bolt of frame 3, removes press fastening device 27, can unload lower screen cloth 25, convenient and efficient.

As shown in Figure 1, pulverizing device frame 3 is fallen to via sieve 25 by the material that hammer leaf 26 shreds, because particle amount is big, in order to Convenient for the timeliness of blanking and the quick collection of blanking, the pulverizing device frame 3 is opening knot far from the side that conveyer belt 4 is fed Structure.

The above description is only the embodiments of the present invention, and therefore it does not limit the scope of the patent of the utility model, all Equivalent structure or equivalent flow shift made based on the specification and figures of the utility model, is applied directly or indirectly in Other relevant technical fields, are also included in the patent protection scope of the utility model.
