Example 1

Referring to fig. 1-2, the present invention provides a low noise and low vibration wood pulverizer, comprising a crushing cylinder 1, wherein the crushing cylinder 1 is a rectangular tube structure, a feed inlet 2 is arranged at the top of the crushing cylinder 1, a snap ring 3 is arranged at the bottom end of the feed inlet 2, the snap ring 3 comprises a plurality of fan-shaped blades, a through hole is arranged at the center inside the snap ring 3, the ends of the plurality of fan-shaped blades are gathered towards the through hole at the center inside the snap ring 3, two first crushing knives 4 are arranged at the center inside of the crushing cylinder 1, a connecting shaft 5 is arranged at the center shaft of the first crushing knives 4, the end of the connecting shaft 5 extends to the outer surface of the crushing cylinder 1, second crushing knives 6 are fixedly arranged at the edges of the two first crushing knives 4, third crushing knives 7 are arranged at the outer sides of the first crushing knives 4, the third crushing knives 7 are respectively arranged on the inner walls at both sides of the crushing cylinder 1, a first motor 8, and first motor 8 fixed mounting is on the outside surface of garrulous feed cylinder 1, and crushing screw 9 is installed to the bottom of first crushing sword 4, and the outside of crushing screw 9 is connected with second motor 10, installs shock pad 11 between crushing screw 9 and the second motor 10, plays the effect that reduces crushing screw 9 vibration, and the bottom of crushing screw 9 is provided with screen cloth 12, and the bottom of garrulous feed cylinder 1 is provided with discharge gate 13, is provided with on the inner wall of garrulous feed cylinder 1 and falls the layer 14 of making an uproar.

Further, snap ring 3 is made by rubber materials, and has the interval between the fan-shaped blade of polylith on the snap ring 3, with timber through 2 back of input garrulous feed cylinder 1 of feed inlet, ligneous gravity pushes down snap ring 3, polylith fan-shaped blade downward sloping on the snap ring 3, increases the through-hole of 3 central authorities of snap ring, smashes through first crushing sword 4 after timber slowly falls.

The interval between two first crushing sword 4 is greater than the interval between two second crushing sword 6, and timber is at crushing in-process, and partial wood residue probably remains on two crushing sword 4, because second crushing sword 6 fixed mounting is on first crushing sword 4, and after first crushing sword 4 rotation, second crushing sword 6 also along with the motion, can play the effect of cutting different bore size timber.

The first crushing cutter 4 is externally connected with a driving device through a connecting shaft 5, and the first crushing cutter 4 is rotationally cut and crushed wood after being externally connected with the driving device through the connecting shaft 5, such as a motor.

First motor 8 and the transmission of third crushing sword 7 are connected, and first motor 8 drives third crushing sword 7 and vertically cuts on the inner wall of garrulous feed cylinder 1, can prevent that timber cutting in-process from blockking up between first crushing sword 4 and garrulous feed cylinder 1 inner wall.

The second motor 10 is in transmission connection with the crushing screw 9, and the second motor 10 drives the crushing screw 9 to transversely rotate in the crushing barrel 1 to crush the wood, so that the effect of further crushing the wood without completely crushing the wood is achieved.

The noise reduction layer 14 is a low-frequency sound-insulation vibration-reduction plate, has good vibration-reduction and sound-insulation effects, and has the effects of low noise and small vibration amplitude, and the plate is the prior known technology.

Specifically, when wood is crushed and cut, after the wood is put into the crushing cylinder 1 through the feeding hole 2, the clamping ring 3 is pressed down by the gravity of the wood, a plurality of fan-shaped blades on the clamping ring 3 incline downwards to form a string bag structure with through holes, the through holes in the center of the clamping ring 3 are increased, the wood slowly falls into the crushing cylinder 1 through the through holes and then is crushed through the first crushing knife 4, after the wood completely falls into the crushing cylinder 1, the clamping ring 3 slowly rebounds due to the characteristic of rubber materials, so that the through holes at the position of the clamping ring 3 are in the initial size, the noise reduction and sound insulation effects can be realized, in the crushing and cutting process of the wood through the first crushing knife 4, as the distance between the first crushing knife 4 is larger than the distance between the two second crushing knives 6, the second crushing knives 6 are fixedly arranged on the first crushing knife 4, and after the first crushing knife 4 rotates, the second crushing knives 6 move along with the wood, can play the effect of cutting different bore size timber, first motor 8 drives third crushing sword 7 and vertically cuts on the inner wall of garrulous feed cylinder 1, can prevent that the timber from cutting the in-process and blockking up between first crushing sword 4 and garrulous feed cylinder 1 inner wall, last second motor 10 drives crushing screw 9 and transversely rotates crushing timber in the inside of a garrulous feed cylinder 1, play further crushing and do not smash the effect of complete timber, the timber after smashing passes through screen cloth 12 and screens and discharges from discharge gate 13, be provided with the low frequency sound insulation vibration damping plate as falling the noise reduction layer 14 on the inner wall of a garrulous feed cylinder 1, can make the timber rubbing crusher have the low noise, the little effect of vibration range.

The utility model discloses because the interval between the first sword 4 of smashing is greater than the interval between the two second smashes sword 6, the second is smashed sword 6 fixed mounting and is on first crushing sword 4, after the rotation of first crushing sword 4, the second is smashed sword 6 and also along with the motion, can play the effect of cutting different bore size timber, prevent that the timber cutting in-process from blockking up between first crushing sword 4 and 1 inner wall of a crushed aggregates section of thick bamboo, can make timber rubbing crusher have the low noise, the effect that the vibration range is little.

Finally, it should be noted that: although the present invention has been described in detail with reference to the foregoing embodiments, it will be apparent to those skilled in the art that modifications may be made to the embodiments described in the foregoing embodiments, or equivalents may be substituted for elements thereof. Any modification, equivalent replacement, or improvement made within the spirit and principle of the present invention should be included in the protection scope of the present invention.
