Field.
Background technique
Pulverizer and the machinery of waste disposal are a kind of common particle equipment, commonly used in waste products such as trees, rubbish
The crushing of material.After the mechanical tooth head of existing pulverizer and stone crusher with driving by being pivotally connected, at work to trees and
The waste products material such as rubbish carries out collision type contact, so that waste product material be smashed；But existing pulverizer and waste disposal are mechanical
Tooth head is made of hard metal material, and under the shock and vibration of material, tooth header structure is easily damaged, even in tooth head
Working head is but not reasonable because of structure design using cemented carbide material etc., easily causes the other positions of tooth head by object
The shock of material needs to be replaced frequently tooth head to keep entire tooth header structure impaired, influences working efficiency, increases use cost.
Summary of the invention
The purpose of the utility model is to overcome the shortcomings of the prior art, and provide a kind of structurally reasonable, use peace
Dress is convenient, and whole tooth header structure fastness is good, wear-resisting, to reduce use cost, improves service life, improves working efficiency
The mechanical tooth head of pulverizer and stone crusher.
The purpose of this utility model is addressed by following technical proposals: a kind of machine of pulverizer and stone crusher
Tool tooth, it includes a block-shaped body, and the side upper end of the block-shaped body is provided with the tooth head portion of wedge angle type, the tooth head
The two sides in portion are respectively arranged with the short slot arcwall face inside contracted, and form the step surface of arc in both wings, in the extension of the step surface
Lower end be provided with vertically downward, more than lower end plane and block-shaped body is the same as wide pillar；The tooth head the-head to
Lower edge is equipped with the block-like, front end bulky grain hard alloy blocks convex in point angle；Another upper lateral part of the block-shaped body
Be provided with assembly through-hole vertically downward in flat surface, and the assembly through-hole lower part be provided with it is comprising assembly through-hole, to
Lower convexity and thickness be no more than pillar cylindrical body.
As preferred: above the bulky grain hard alloy blocks in tooth head portion and front is arranged by boundary of center line respectively
The oriented inclined inclined-plane in two sides, extands rearward to always above the block-shaped body of connection above, passes through no more than middle position
Be facing perpendicularly to down be transitioned into fit on plane, the fit on plane is arranged in the assembly through-hole, before always downwards
It is extended down under and pillar bottom surface after arc inside contracts again after in the middle part of extending to；The block-shaped body two sides go ahead from rear end is in
The arc-shaped transition inside contracted is constituted together with the inclined-plane that front arc-shaped step face and front arc inside contract to the step surface of front arc
The step surface that three stratiforms inside contract；The rear end face of the block-shaped body is provided with two sides evagination, the interior vertical configuration groove in through slot type.
The utility model is improvements over the prior art, it has structurally reasonable, easy to install and use, whole tooth header structure
The features such as fastness is good, wear-resisting, to reduce use cost, improves service life, and improves working efficiency.
Detailed description of the invention
Fig. 1 is the structural schematic diagram of the utility model.
Fig. 2 is the A direction view of Fig. 1.
Fig. 3 is the B direction view of Fig. 1.
Specific embodiment
The utility model is described in detail below in conjunction with attached drawing: shown in Fig. 1-3, one kind described in the utility model
The mechanical tooth of pulverizer and stone crusher, it includes a block-shaped body 1, and the side upper end of the block-shaped body 1 is provided with wedge angle
The tooth head portion 2 of type, the two sides in tooth head portion 2 are respectively arranged with the short slot arcwall face 3 inside contracted, and form arc in both wings
Step surface 4, the extension lower end of the step surface 4 be provided with vertically downward, it is more than lower end plane 5, with tooth head ontology 1
With wide pillar 6；Tooth head portion 2 is inlayed downwardly over is equipped with a block-like, front end in the bulky grain hard of point angle convex 7
Alloy block 8；Assembly through-hole 10 vertically downward is provided in the other side fit on plane 9 of the block-shaped body 1, and described
Assembly 10 lower part of through-hole is provided with the cylindrical body 11 that comprising assembly through-hole, downwardly convex and thickness is no more than pillar 6.
As shown in the figure, the bulky grain hard alloy blocks 8 in tooth head portion 2 are set by boundary of center line with front respectively above
It is equipped with to the inclined inclined-plane 12 in two sides, is extanded rearward to always above the block-shaped body 1 of connection above, be no more than middle position
It is transitioned into fit on plane 9 downwards by vertical plane 13, the fit on plane 9 is arranged in the assembly through-hole 10, preceding
Face extends downward into always behind middle part and is extended down under and 6 bottom surface of pillar after arc inside contracts 14 again；1 two sides of block-shaped body from
