Description

Cutter for crusher

Technical Field

The application relates to the technical field of crusher parts, in particular to a movable cutter.

Background

The existing cutters of the crusher are integrally formed, the cutters are repaired by overlaying after being worn, and the cutters are treated as waste after the repairing times reach the limit.

The integrally formed cutter consumes materials, and the whole cutter is used as a waste part after the service life is reached, so that the condition of resource waste exists.

Disclosure of Invention

In order to save the resources that the cutter consumes, this application provides a cutter for breaker.

The application provides a cutter for breaker adopts following technical scheme:

the utility model provides a cutter for breaker, is including being blade holder and the blade that can dismantle the connection, the shaping has the sword tooth on the blade holder, blade holder and blade are different material goods, and the blade is a plurality of, and is a plurality of the blade distributes in the both sides face of blade holder, the blade encircles the central evenly distributed of blade holder be provided with the sword groove on the blade holder, the sword groove is the dovetail, the sword inslot has the sword piece, sword piece and blade are same material.

Preferably, both sides of the cutter are provided with blade grooves for accommodating the blades, the blades are arc plates, cutting protrusions are formed on the blades and attached to cutter teeth of the cutter holder, and one side of each blade is provided with a thrust notch.

Preferably, the outer edge of the blade protrudes beyond the outer edge of the seat.

Preferably, the side of the knife block far away from the center of the knife seat is flush with the outer edge of the knife blade.

Preferably, the thrust notch is concave towards a direction away from the centre of the holder.

In summary, the present application includes at least one of the following beneficial technical effects: the cutter of the crusher adopts a split type, when the cutter is worn, the cutter blade and the cutter block are worn firstly, so that the service life can be prolonged; in addition, when the bolt is used, partial shearing stress of the bolt is shared by the thrust notch, and damage and breakage of the bolt are reduced.

Description of reference numerals: 1. a tool apron; 11. cutter teeth; 2. a blade; 21. cutting the bulge; 22. a thrust notch; 3. and a knife block.

Detailed Description

The present application is described in further detail below with reference to the attached drawings.

The embodiment of the application discloses cutter for breaker.

Referring to fig. 1 and 2, cutter for breaker is including being blade holder 1 and the blade 2 that can dismantle the connection, the shaping has sword tooth 11 on the blade holder 1, blade holder 1 and blade 2 are different material goods, and blade 2 is a plurality of, and is a plurality of blade 2 distributes in the both sides face of blade holder 1, blade 2 encircles the central evenly distributed of blade holder 1, all sets up the perforation that a plurality of confession bolts passed on every blade 2, and blade 2 and cutter pass through bolted connection.

The knife holder 1 is provided with a knife groove which is a dovetail groove, a knife block 3 is embedded in the knife groove, the knife block 3 and the blade 2 are made of the same material, the knife block 3 is positioned on one side of the knife teeth 11 contacting with a broken material, and one side surface of the knife block 3 is supported by the knife teeth 11.

In order to reduce the protrusion of the blade 2 out of the tool holder 1 and increase the overall thickness, the two side surfaces of the tool are both provided with a blade groove for accommodating the blade 2, the blade 2 is an arc plate, a cutting bulge 21 is formed on the blade 2, and the cutting bulge 21 is attached to the side surface of the cutter tooth 11 of the tool holder 1.

A thrust notch 22 is provided at one side of the blade 2. The thrust notch 22 is concave towards the direction far away from the center of the tool apron 1; because during the cutting, blade holder 1 drives blade 2 on it to rotate and to cut the material, and the bolt of connecting blade holder 1 and blade 2 receives the shearing force on the contact surface of blade holder 1 and blade 2, appears the cracked phenomenon of bolt easily, consequently the thrust breach 22 conducts the power of blade 2 to blade holder 1 to this shearing force that reduces the bolt and received.

In order to prolong the service life of the cutter, the outer edge of the blade 2 protrudes out of the outer edge of the cutter holder 1, when in use, the partial blade 2 protruding out of the cutter holder 1 is worn firstly until the part of the blade 2 protruding out of the cutter holder 1 is completely worn, after the blade 2 and the cutter holder 1 are worn and leveled, the blade 2 and the cutter holder 1 are worn at the same time, and after the blade 2 and the cutter holder are worn more again, surfacing repair is carried out.

The blade 2 protruding out of the blade holder 1 is easy to bend due to the thin thickness, one side of the blade block 3 away from the center of the blade holder 1 is flush with the outer edge of the blade 2, and the blade block 3 is supported by the blade holder 1, is not easy to bend and supports the blades 2 on two sides of the blade block; in addition, the position of the cutter block 3 is contacted with materials, so that the probability that the cutter blade 2 is contacted with the materials can be reduced.

The above embodiments are preferred embodiments of the present application, and the protection scope of the present application is not limited by the above embodiments, so: all equivalent changes made according to the structure, shape and principle of the present application shall be covered by the protection scope of the present application.
