Abstract

A kind of chipper tooth head, it includes a square bulk tooth head body, described tooth head body upper surface is work surface, and the work surface is made up of in the tangent circular arc end face for being formed in tooth head body upper surface a spherical surface body, and makes four corners form convex sharp sharp knife angle；The lower surface of the tooth head body is fitting surface, and the middle setting of the fitting surface has a counter sink, and the middle setting in counter sink has positioning threads through hole vertically upward；Four sides of the tooth head body are the inclined-plane for inside contracting from the top down, form four bullets of the top area more than bottom area, and four arms of angle between four sides are respectively arranged with chamfered transition side；It has rational in infrastructure, and easy to install and use, overall tooth header structure fastness is good, wear-resisting, so as to reduce use cost, the features such as improve work efficiency.

Description

Chipper tooth head

Technical field

The utility model relates to a kind of chipper tooth head, belongs to particle mechanical equipment technical field.

Background technology

Material disintegrator is a kind of common particle equipment, is generally used for the crushing of trees and rubbish.The machine tooth of existing Material disintegrator After pivotally connected with driving, collision type contact is carried out to trees and rubbish at work, so as to material is smashed；But Existing Material disintegrator machine tooth is made using hard metal material, and under the shock and vibration of material, tooth header structure is easily damaged, i.e., Using Hardmetal materials etc. but not reasonable because of structure design in the working head of tooth head, easily cause tooth head its Its position is clashed into by material, so that whole tooth header structure is damaged, it is often necessary to even if changing tooth head, affect work effect Rate, increases use cost.

The content of the invention

The purpose of this utility model is to overcome the shortcomings of that prior art is present, and provides a kind of rational in infrastructure, using peace Dress is convenient, and overall tooth header structure fastness is good, wear-resisting, so as to reduce use cost, improves the chipper tooth head of work efficiency.

The purpose of this utility model is addressed by following technical proposals：A kind of chipper tooth head, it includes one Square bulk tooth head body, described tooth head body upper surface is work surface, and the work surface is in tooth head sheet by a spherical surface body The circular arc end face of the tangent formation in body upper surface is constituted, and makes four corners form convex sharp sharp knife angle；The tooth head sheet The lower surface of body is fitting surface, and the middle setting of the fitting surface has counter sink, and the middle setting in counter sink has vertically upward Positioning threads through hole.

As preferred：Four sides of the tooth head body are the inclined-plane for inside contracting from the top down, form a top area More than four bullets of bottom area, four arms of angle between four sides are respectively arranged with chamfered transition side.

This utility model is improvements over the prior art, and it has rational in infrastructure, easy to install and use, overall tooth header structure Fastness is good, wear-resisting, so as to reduce use cost, the features such as improve work efficiency.

Description of the drawings

Fig. 1 is structural representation of the present utility model.

Fig. 2 is the A direction views of Fig. 1.

Fig. 3 is the B direction views of Fig. 1.

Specific embodiment

This utility model is described in detail below in conjunction with accompanying drawing：Shown in Fig. 1-3, one kind described in the utility model Chipper tooth head, it includes a square bulk tooth head body 1, and described 1 upper surface of tooth head body is work surface 2, the work Face 2 is made up of in the tangent circular arc end face for being formed in 1 upper surface of tooth head body a spherical surface body, and makes four corners form convex Sharp knife angle 3；The lower surface of the tooth head body 1 is fitting surface 4, and the middle setting of the fitting surface 4 has counter sink 5, and in countersunk head The middle setting in hole 5 has positioning threads through hole 6 vertically upward.

Shown in figure, four sides of the tooth head body 1 are the inclined-plane 7 for inside contracting from the top down, form a upper side Four bullets of the product more than bottom area, four arms of angle between four sides are respectively arranged with chamfered transition side 8.

This utility model adopts four sharp nose angles（Sharp knife angle 3）And knife-edge design, substantially increase the work of product Efficiency, single screwed hole design play good positioning action.

Claims

1. a kind of chipper tooth head, it includes a square bulk tooth head body, it is characterised in that described tooth head body upper end Face is work surface, and the work surface is made up of in the tangent circular arc end face for being formed in tooth head body upper surface a spherical surface body, and makes four Individual corner forms convex sharp sharp knife angle；The lower surface of the tooth head body be fitting surface, the middle setting of the fitting surface There is a counter sink, and the middle setting in counter sink has positioning threads through hole vertically upward.

2. chipper tooth head according to claim 1, it is characterised in that four sides of the tooth head body are from upper The inclined-plane for inside contracting downwards, forms four bullets of the top area more than bottom area, four arms of angle between four sides point Chamfered transition side is not provided with.
