Description

Tearing machine blade

Technical Field

The patent of the utility model relates to a tool bit structure of tear machine, specifically speaking relates to a tear machine blade.

Background

The tearing machine is widely applied to the treatment of construction waste, decoration waste and household waste, mainly aims at the tearing and bag breaking of soft strip-shaped materials such as plastics, rubber, cloth, wood blocks and the like in the waste, and also can give consideration to the breaking function of some hard materials. As shown in fig. 1, 2 and 3, the two sets of blades are staggered to form a scissors-like structure, and when the two sets of blades rotate relatively, the material can be cut or shredded like scissors. However, the blade is worn most quickly at the edge part, once the blade is worn, the blade grinding is removed, which is time-consuming and labor-consuming, and after two or three times of grinding, the height of the edge part is greatly reduced, the effects of biting materials and shearing and tearing cannot be achieved, the blade is scrapped, the running cost is high, and the blade is basically intact except the edge is worn (generally, the blade is manufactured by spring steel plus quenching, which is expensive), and is very uneconomical.

SUMMERY OF THE UTILITY MODEL

The utility model aims at providing a tear machine blade, the tool bit can be changed to the tool bit is made with carbide, erects admittedly wear-resisting.

The purpose of the utility model is realized through the following technical scheme:

a tearing machine blade comprises a blade body, and at least two alloy blade heads are fixed on the blade body through bolts.

The alloy cutter head of the tearing machine blade consists of a cutter blade body and hard alloy embedded on the cutter blade body.

The alloy cutter head is brazed on the cutter body.

The alloy cutter head of the tearing machine blade is of a symmetrical structure.

The blade body between adjacent alloy cutter heads of the tearing machine blade is also provided with an auxiliary cutter head.

Adopt above-mentioned technical scheme, the utility model discloses following beneficial technological effect has:

the utility model discloses a blade for removable cutting edge to the cutting edge is made with carbide, and is firm wear-resisting, has an auxiliary blade simultaneously in the middle of the working circle of per two cutting edges, plays a function of helping to bite into the material.

Detailed Description

The structure and operation of the present invention will be described in detail with reference to fig. 4 and 5.

In the drawings, the reference numbers are as follows:

1. alloy tool bit, 2, bolt, 3, blade body, 4, auxiliary tool bit, 5, blade body, 6, carbide.

In the description of the present invention, it is to be understood that the terms "center", "radial", "lateral", "length", "width", "thickness", "upper", "lower", "front", "rear", "left", "right", "vertical", "horizontal", "top", "bottom", "inner", "outer", "clockwise", "counterclockwise", and the like indicate orientations or positional relationships based on the orientations or positional relationships shown in the drawings, and are only for convenience of description and to simplify the description, but do not indicate or imply that the device or component referred to must have a particular orientation, be constructed and operated in a particular orientation, and therefore should not be construed as limiting the present invention.

In the present invention, unless otherwise expressly stated or limited, the terms "mounted," "connected," and "fixed" are to be construed broadly and may, for example, be fixedly connected, detachably connected, or integrally formed; either directly or indirectly through intervening media, either internally or in any other relationship. The specific meaning of the above terms in the present invention can be understood according to specific situations by those skilled in the art.

As shown in fig. 4 and 5, the tearing machine blade comprises a blade body 3, at least two alloy cutting heads 1 are arranged on the blade body, and the alloy cutting heads 1 are fixed on the blade body 3 through bolts 2. The alloy cutter head on the blade body is convenient to replace.

The alloy tool bit of the utility model consists of a blade body 5 and a hard alloy 6 embedded on the blade body.

Alloy tool bit is symmetrical structure, after 1 wearing and tearing of alloy tool bit, loosens bolt 2, transfers 180 with the tool bit, continues to use after screwing up with bolt 2.

The utility model discloses still be provided with vice tool bit 4 on the blade body between the adjacent alloy tool bit, play a function of helping to bite the material.

The working principle of the utility model is as follows:

as shown in figures 2 and 3, when the two rows of blades rotate relatively, the alloy cutter head 1 bites materials and forms a scissor structure to shred the materials, when the alloy cutter head 1 is worn, the bolt 2 is loosened, the cutter head is turned by 180 degrees and is screwed by the bolt 2 to be continuously used, and the alloy cutter head is completely and symmetrically designed.

When two working faces of the alloy cutter head 1 are worn and failed, the bolt 2 can be loosened, the alloy cutter head 1 can be replaced by a new one, the blade body 3 can be repeatedly used without detaching the blade.

The raised secondary tips 4 of the blade body 3 serve as auxiliary engagement means for engaging the material, which increases the shredding effect and also increases the output of the shredder.

If the auxiliary cutter head 4 is worn, hard wear-resistant welding materials can be used for surfacing, because the material of the alloy cutter blade 3 does not use a method of quenching high-carbon steel, but uses a method of quenching and tempering medium-carbon steel, the weldability is greatly improved, and the manufacturing cost is lower than that of the traditional cutter blade.

What has been described above is only the preferred embodiments of the present invention, and it should be noted that, for those skilled in the art, without departing from the overall concept of the present invention, a plurality of changes and improvements can be made, and these should also be regarded as the protection scope of the present invention, and these will not affect the effect of the present invention and the utility of the patent.
