Description

Technical Field

[0001] The utility model belongs to the technical field of blade improvement structure and relates to a rhombus self-sharpening knife. Background Art

[0002] The impact gyratory crusher uses high-speed rotation to throw out the blade, which collides with the material through the blade edge as the shaft rotates to crush the material.

[0003] The blades on both sides of the traditional blade are convex towards the middle, and the convex parts are relatively sharp. After it continuously collides with stones, the blade edge is easily worn due to the thin thickness of the sharp part of the blade, and the blade life is short. Utility Model Content

[0004] The utility model aims to solve the above problems in the prior art and proposes a diamond-shaped self-sharpening knife.

[0005] The purpose of the utility model can be achieved through the following technical solutions: a diamond-shaped self-sharpening knife, comprising a knife body and a handle arranged on the knife body, the width of the knife body away from the handle is greater than the width of the knife body close to the handle, blade parts are respectively arranged on both sides of the knife body, the blade parts include a first blade and a second blade, the first blade is vertically arranged, and the second blade is an inclined surface cut toward the bottom of the knife body.

[0006] In the above-mentioned diamond-shaped self-sharpening knife, the width of the first blade gradually increases toward the handle side.

[0007] In the above-mentioned diamond-shaped self-sharpening knife, the blade portions on both sides are arranged in a centrally symmetrical manner.

[0008] In the above-mentioned diamond-shaped self-sharpening knife, the handle and the knife body are designed in an integrated manner. The handle and the knife body are melted in an integrated manner using a mold to avoid forming a connection point at the connection between the handle and the knife body, thereby preventing the handle and the knife body from breaking after the self-sharpening knife is used for a long time.

[0009] In the above-mentioned diamond-shaped self-sharpening knife, a mounting hole is provided on the knife handle, and a worker can install the knife handle on the knife disc by passing a bolt through the mounting hole, which is convenient for the worker to install and disassemble.

[0010] In the above-mentioned diamond-shaped self-sharpening knife, the side of the knife body away from the knife handle is arranged in a parallelogram shape.

[0011] Compared with the prior art, the utility model provides a first blade and a second blade, wherein the first blade is in a vertical state and its thickness gradually becomes wider, so that the connecting portion of the first blade and the second blade has a certain thickness, thereby avoiding the occurrence of notches in the blade after the knife hits the stone for a long time, thereby improving the service life of the self-sharpening knife; at the same time, the second blade has an inclined surface cut toward the bottom of the blade body, which can increase the contact area between the blade and the stone, thereby making the stone smaller after being crushed.

[0014] The following are specific embodiments of the present invention and the accompanying drawings to further describe the technical solution of the present invention, but the present invention is not limited to these embodiments.

[0015] Example

[0016] like Figure 1 As shown, a diamond-shaped self-sharpening knife comprises a knife body 1 and a knife handle 2 arranged on the knife body 1, wherein the knife handle 2 is designed as an integral part with the knife body 1. The knife handle 2 and the knife body 1 are integrally melted by a mold to avoid forming a connection point at the connection between the knife handle 2 and the knife body 1, thereby preventing the knife handle 2 and the knife body 1 from breaking after the self-sharpening knife is used for a long time.

[0017] The width of the blade body 1 at the side away from the handle 2 is greater than the width of the blade body 1 at the side close to the handle 2. Blade parts 3 are respectively arranged on both sides of the blade body 1, and the blade parts 3 on both sides are arranged symmetrically to the center.

[0018] The blade portion 3 includes a first blade 31 and a second blade 32 , and the width of the first blade 31 gradually increases toward the handle 2 .

[0019] The first blade 31 is vertically arranged, and the second blade 32 is an inclined surface inclined toward the bottom of the blade body 1 .

[0020] The handle 2 is provided with a mounting hole 4. The staff can install the handle 2 on the cutter head by passing a bolt through the mounting hole 4, which is convenient for the staff to install and disassemble.

[0021] The side of the knife body 1 away from the knife handle 2 is arranged in a parallelogram shape.

[0022] The utility model provides a first blade 31 and a second blade 32. The first blade 31 is in a vertical state and its thickness gradually becomes wider, so that the connecting portion of the first blade 31 and the second blade 32 has a certain thickness, thereby avoiding the occurrence of a notch in the blade after the knife hits the stone for a long time, thereby improving the service life of the self-sharpening knife; at the same time, the second blade 32 is an inclined surface cut toward the bottom of the knife body 1, which can increase the contact area between the blade portion 3 and the stone, so that the stone can be broken into smaller pieces.

[0023] The specific embodiments described herein are merely examples of the spirit of the present invention. Those skilled in the art may make various modifications or additions to the specific embodiments described or replace them in similar ways, but they will not deviate from the spirit of the present invention or exceed the scope defined by the appended claims.
