Description

Pommel horse type crusher tooth head

Technical Field

The invention relates to the technical field of machinery, in particular to a pommel horse type crusher tooth head.

Background

The crusher is a common large crusher, a tooth head of the crusher is a consumable product which is very easy to damage, so that the tooth head can be durable, under a common condition, alloy materials are embedded on the surface of the tooth head or in the tooth head, the tooth head is more wear-resistant, the tooth head is not uniformly worn due to the fact that the alloy materials are arranged on the surface or embedded in the tooth head, the whole surface is embedded possibly, only a small block is formed when the tooth head is seriously worn, the abrasion is very waste, and the shape of the tooth head is also very related to the position of abrasion.

Disclosure of Invention

An object of the utility model is to overcome the portion that prior art exists enough, and provide a structural design reasonable, the installation is fixed convenient, wear-resisting, the fastness is strong, long service life reduces use cost, improves work efficiency's a pure machine's of powder mechanical toothholder.

The utility model aims at accomplishing through following technical scheme, a pommelled horse type crushed aggregates machine tooth head, it includes the tooth head body of pommelled horse form, the top both ends of tooth head are equipped with the sharp bight of perk that makes progress respectively, and wherein the top of the sharp bight of one end is equipped with a recess that is used for putting the stereoplasm alloy layer, the terminal surface is provided with the skew front of S-shaped before the tooth head body of tooth head below, and this inclined plane extends to both sides all the way to on the both sides socle of bottom, tooth head bottom is equipped with the bottom surface of a parallel, and is 90 degrees vertically between the socle, forms the assembly bottom surface of an L shape, be equipped with a bellied oval-shaped locating hole on this assembly bottom surface, be equipped with 2 circular and the inside pilot hole of body directly in the locating hole.

Preferably, the method comprises the following steps: an embedding groove is transversely and downwards formed in the sharp corner part at the top end of the tooth head body, and a hard alloy block is transversely embedded and fixed in the embedding groove; the center of the top of the tooth head body extends to the sharp corner part towards two sides and is bent to form a concave surface, so that a saddle-shaped top is formed; and a row of uniformly distributed granular hard alloy layers are embedded on the surface of the sharp corner part on one side of the hard alloy block.

Preferably, the method comprises the following steps: granular hard alloy layers which are uniformly distributed are respectively welded on the bottom edges of the two sides of the leg columns, the length of the leg columns on the two sides is larger than that of the tooth body, and two fixed mounting holes are respectively symmetrically formed in the left side surface and the right side surface of the tooth body.

The utility model belongs to the improvement to prior art, it has structural design rationally, and the installation is fixed convenient, and is wear-resisting, fastness is strong, long service life, reduces use cost, improves characteristics such as work efficiency.

Detailed Description

The present invention will be described in detail with reference to the accompanying drawings: fig. 1-2 show, a pommel horse type crushed aggregates machine tooth head, it includes the tooth head body 1 of pommel horse form, the top both ends of tooth head are equipped with the sharp bight 2 of perk that makes progress respectively, wherein the top of the sharp bight of one end is equipped with a recess 3 that is used for putting the stereoplasm alloy layer, tooth head body front end face of tooth head below the tooth head is provided with the oblique front surface 4 of S-shaped, and this inclined plane extends to both sides all the way to the both sides socle 5 of bottom on, tooth head bottom is equipped with a parallel bottom surface 6, and is 90 degrees perpendicular 7 between the socle 5, forms the assembly bottom surface 8 of an L shape, be equipped with a bellied oval-shaped locating hole 9 on this assembly bottom surface 8, be equipped with 2 circular and the inside pilot hole 10 of body in the locating hole 9 directly.

As shown in the figure: an embedding groove 11 is transversely and downwards formed in the sharp corner part at the top end of the tooth head body, and a hard alloy block 12 is transversely embedded and fixed in the embedding groove; the center of the top of the tooth head body 1 extends to the sharp corner 2 towards two sides and is bent to form a concave surface 13, so that a saddle-shaped top is formed; a row of granular hard alloy layers 14 which are uniformly distributed are embedded on the surface of the sharp corner part 2 at one side of the hard alloy block 12.

The bottom edges of two sides of the leg post 5 are respectively welded with granular hard alloy layers 15 which are uniformly distributed, the length of the leg post at two sides is greater than that of the tooth body, and two fixed mounting holes 16 are respectively symmetrically arranged on the left side surface and the right side surface of the tooth body.

The tooth head is a saddle-shaped tooth head, the wear-resistant point of the tooth head is the sharp corner part of two ends, the design can enable stress to be concentrated, the stress point is provided with a hard alloy layer, and a granular hard alloy layer is added near the alloy layer, so that the double-layer wear-resistant tooth head is durable, the durability of the tooth head is durable, and the granular hard alloy layer is arranged at the position of the connecting hole at the bottom, so that the stress protection of the connecting position is protected, and the tooth head is durable. The replacement frequency is reduced.
