Description

Technical Field

[0001] The utility model relates to the technical field of triangular blades for crushing silicon dioxide materials, in particular to a wear-resistant tungsten steel triangular blade. Background Art

[0002] Triangular blades are used to crush silica and are generally installed in crushing equipment. The shape of this blade has obvious advantages. The triangular design can produce efficient cutting and impact effects on silica during rotation. Its edge can cut into the space between silica particles like a sharp blade, and its surface frequently collides with particles during high-speed rotation, gradually crushing the silica into smaller pieces. The material of the blade usually has high hardness and good wear resistance to resist the wear of hard materials such as silica. At the same time, a reasonable installation angle is also critical, which can ensure that the material is fully turned over during the crushing process to ensure uniform crushing effect.

[0003] Existing triangular blades often suffer from severe wear during welding, causing the blades to fall off during operation, and the service life of the working blades is short. Utility Model Content

[0004] In order to overcome the above technical problems, the utility model provides a wear-resistant tungsten steel triangular blade to improve the problems of weak welding and poor wear resistance.

[0005] In order to achieve the above-mentioned purpose, the utility model proposes a wear-resistant tungsten steel triangular blade, including a gear ring and a blade, a plug-in groove recessed into the interior of the gear ring is formed on the contact surface between the gear ring and the blade, a plug-in strip matching the plug-in groove structure is formed on the contact surface between the blade and the gear ring, and the contact surface between the blade and the gear ring is connected by welding.

[0006] Triangular blades are commonly used to crush silica materials. Because silica is a hard material, the triangular blades will quickly wear out when they collide with the silica material. Therefore, triangular blades are commonly used in structures where the blades are welded to a ring gear. When the blades are worn, the ring gear can replace the worn blades with new ones and continue to use them. The connection between the blades and the ring gear is more critical. If the connection is unstable, the blades will fall off during the collision and wear with the silica material.

[0007] A plug-in groove is set on the gear ring, and a plug-in strip is set on the blade. The blade is plugged into the gear ring, and then the blade and the gear ring are welded. This greatly increases the connection force between the blade and the gear ring. The stability and firmness far exceed direct welding, thereby enhancing the firmness between the blade and the gear ring.

[0008] Preferably, the cross section of the insertion slot perpendicular to the length direction is hexagonal.

[0009] The cross section of the insertion slot is hexagonal, the two sides are inclined surfaces and the upper and lower sides are parallel planes. The two sides are the main force bearing surfaces. When the blade rotates with the gear ring, the two sides bear the pressure. Therefore, the larger the inclined surface is, the greater the bearing capacity is, and the greater the support force on the insertion strip is.

[0010] Preferably, the insertion strip comprises an upper plane, a lower plane and an inclined plane, and the elastic expansion strip is mounted on the inclined plane.

[0011] The elastic expansion strip is arranged on the inclined plane of the insertion strip. When the insertion strip is inserted into the insertion slot, the elastic expansion strip can fasten the insertion strip, so that the inserted insertion strip does not shake due to the existence of a small gap around, thereby causing the subsequent welding to crack. In addition, the insertion strip also has a certain support force. Before welding, the insertion strip is tightly fixed with the insertion slot to form a support force.

[0012] Preferably, one end of the elastic expansion strip is fixed to the inclined plane, and the other end abuts against the inclined plane.

[0013] One end of the elastic expansion strip is fixed to the inclined plane, and the other end abuts against the inclined plane. When the elastic expansion strip is inserted into the insertion slot and bears a force, the abutting end of the elastic expansion strip automatically expands according to the force condition, so that the elastic expansion strip has both elastic support force and adjustable elastic space, and the insertion strip is more easily inserted into the insertion slot.

[0014] Preferably, the insertion slot is formed with anti-slip lines circumferentially surrounding the side wall of the insertion slot.

[0015] The anti-slip lines are arranged in the insertion slot. The main function is to cooperate with the elastic expansion strip to increase the friction force between the elastic expansion strip and the insertion slot, so as to ensure the stability of the insertion strip.

[0016] Preferably, the contact surface of the elastic expansion strip with the inner wall of the insertion slot is formed with anti-slip grooves.

[0017] The anti-slip grooves are formed on the elastic expansion strip, which also play a role of anti-slip in cooperation with the anti-slip lines.

[0018] Preferably, the blade is made of tungsten steel.

[0019] The blade is made of tungsten steel, which has greater hardness and is not easy to be worn by silicon dioxide, thereby increasing the service life of the blade.

[0020] Preferably, the gear ring is made of iron-tungsten alloy.

[0021] The gear ring is made of iron-tungsten alloy. The iron-tungsten alloy has good toughness and good bending performance in work rotation, and is not easy to break.

[0022] The wear-resistant tungsten steel triangular blade provided by the utility model is provided with a plug-in groove on the gear ring and a plug-in strip on the blade. The blade and the gear ring are plugged and then welded together, so that the blade and the gear ring are not only fixed by welding. The plug-in groove can provide a certain supporting force for the plug-in strip, so that the blade is more firmly combined with the gear ring when working. In addition, the blade is made of tungsten steel, which is more wear-resistant and not easy to be damaged. BRIEF DESCRIPTION OF THE DRAWINGS

[0028] The following describes embodiments of the present invention with reference to the accompanying drawings. Elements and features described in one drawing or one embodiment of the present invention may be combined with elements and features shown in one or more other drawings or embodiments. It should be noted that for the sake of clarity, the drawings and descriptions omit the representation and description of components or processes that are not relevant to the present invention and are known to those of ordinary skill in the art.

[0029] The present invention will be further described below in conjunction with the accompanying drawings.

[0030] like Figures 1 to 3 As shown, the wear-resistant tungsten steel triangular blade provided by the utility model includes a gear ring 1 and a blade 2. A plug-in groove 3 recessed into the interior of the gear ring 1 is formed on the contact surface between the gear ring 1 and the blade 2. A plug-in strip 4 matching the structure of the plug-in groove 3 is formed on the contact surface between the blade 2 and the gear ring 1. The contact surface between the blade 2 and the gear ring 1 is connected by welding.

[0031] Triangular blades are commonly used to crush silica materials. Since silica is a hard material, the triangular blades will quickly wear out when they collide with the silica material. Therefore, triangular blades are commonly used with a structure where the blade 2 is welded to the ring gear 1. When the blade 2 is worn, the ring gear 1 can replace the worn blade 2 with a new blade 2 and continue to use it. The connection between the blade 2 and the ring gear 1 is more critical. If the connection structure is unstable, the blade 2 will fall off during the collision and wear with the silica material.

[0032] A plug-in groove 3 is provided on the gear ring 1, and a plug-in strip 4 is provided on the blade 2. The blade 2 is plugged into the gear ring 1, and then the blade 2 and the gear ring 1 are welded, so that the connection force between the blade 2 and the gear ring 1 is greatly increased, and the stability and firmness far exceed direct welding, thereby enhancing the firmness between the blade 2 and the gear ring 1.

[0033] In one embodiment of the present invention, the cross section of the plug slot 3 perpendicular to the length direction is hexagonal.

[0034] The cross-section of the plug-in slot 3 is set to be hexagonal, and the inclined surfaces extending to both sides are parallel to each other above and below. The inclined surfaces on both sides are the main force-bearing surfaces. When the blade 2 rotates with the gear ring 1, the inclined surfaces on both sides bear the pressure. Therefore, the larger the inclined surface connection, the greater the bearing capacity, and the greater the supporting force on the plug-in strip 4.

[0035] In one embodiment of the present invention, the plug-in strip 4 includes an upper plane, a lower plane, and an inclined plane 5 , and an elastic expansion strip 6 is installed on the inclined plane 5 .

[0036] An elastic expansion strip 6 is provided on the inclined plane 5 on the plug-in strip 4, so that the plug-in strip 4 can be fastened by the elastic expansion strip 6 when inserted into the plug-in slot 3, so that the plug-in strip 4 will not shake due to the presence of tiny gaps around it, thereby causing subsequent welding cracks. In addition, it also provides a certain supporting force for the plug-in strip 4. Before welding, the plug-in strip 4 is tightly fixed to the plug-in slot 3 to form a supporting force.

[0037] In one embodiment of the present invention, one end of the elastic expansion strip 6 is fixed to the inclined plane 5 , and the other end thereof abuts against the inclined plane 5 .

[0038] One end of the elastic expansion strip 6 is fixed to the inclined plane 5, and the other end is not fixed. When the elastic expansion strip 6 is inserted into the plug-in slot 3 and subjected to force, the abutting end of the elastic expansion strip 6 automatically extends according to the force conditions, so that the elastic expansion strip 6 has both elastic supporting force and adjustable elastic space, making it easier for the plug-in strip 4 to be inserted into the plug-in slot 3.

[0039] In one embodiment of the present invention, anti-slip grooves are formed in the plug-in slot 3 and circumferentially surround the side wall of the plug-in slot 3 .

[0040] Anti-slip grooves are provided in the plug-in slot 3 , the main function of which is to cooperate with the elastic expansion strip 6 , increase the friction between the elastic expansion strip 6 and the plug-in slot 3 , and ensure the stability of the plug-in strip 4 .

[0041] In one embodiment of the present invention, an anti-slip groove is formed on the contact surface of the elastic expansion strip 6 with the inner wall of the plug-in slot 3 .

[0042] The anti-skid grooves are formed on the elastic expansion strip 6 to cooperate with the anti-skid patterns to play an anti-skid role.

[0043] In one embodiment of the present invention, the blade 2 is made of tungsten steel.

[0044] The blade 2 is made of tungsten steel, which has greater hardness and is not easily worn by silicon dioxide, thereby increasing the service life of the blade 2.

[0045] In one embodiment of the present invention, the gear ring 1 is made of iron-tungsten alloy.

[0046] The gear ring 1 is made of iron-tungsten alloy, which has good toughness, good bending performance during working rotation, and is not easy to break.

[0047] The wear-resistant tungsten steel triangular blade provided by the utility model is provided with a plug-in groove 3 on the gear ring 1 and a plug-in strip 4 on the blade 2. The blade 2 and the gear ring 1 are plugged and then welded together, so that the blade 2 and the gear ring 1 are not only fixed by welding. The plug-in groove 3 can provide a certain supporting force for the plug-in strip 4, so that the blade 2 is more firmly combined with the gear ring 1 when working. In addition, the blade 2 is made of tungsten steel, which is more wear-resistant and not easy to be damaged.
