Description

Technical Field

[0001] The utility model belongs to the technical field of sand making machines, and particularly relates to a throwing head for a mine sand making machine. Background Technique

[0002] The throwing head belongs to the core part of a vertical impact crusher (sand making machine), and is widely used in industries such as mines, sand and gravel, cement, metallurgy, and hydropower projects. The throwing head is fixedly installed on the rotor of the sand making machine. When the sand making machine operates, the rotor drives the throwing head to rotate together, and collides with the thrown materials at high speed, thereby crushing large-particle and high-hardness materials. The throwing head is composed of a matrix and carbide bars. The carbide bars are embedded at the bottom of the matrix and bonded with glue.

[0003] During the working process of the existing sand making machine, it will be continuously impacted and rubbed by the materials, which causes wear of the throwing head and requires continuous replacement. This not only affects the working efficiency of the sand making machine but also increases the economic cost. Therefore, we propose a throwing head for a mine sand making machine. Content of the Utility Model

[0004] The purpose of the utility model is to provide a throwing head for a mine sand making machine to solve the problem of the short service life of the throwing head of the existing sand making machine mentioned in the above background technique.

[0005] To achieve the above purpose, the utility model provides the following technical solution: A throwing head for a mine sand making machine, including a steel sleeve. One end of the steel sleeve is provided with a throwing head main body. The outer side of the throwing head main body is provided with a wear-resistant alloy layer. One end of the throwing head main body is provided with an installation groove. The inner side of the installation groove is provided with carbide bars. The inner side of the installation groove is provided with urethane sealant. The bottom end of the steel sleeve is provided with an installation block. The surface of the installation block is provided with threaded holes. The inner side of the steel sleeve is provided with a fixing groove. The inner side of the fixing groove is provided with a connecting rod.

[0006] Preferably, one end of the steel sleeve is fixedly welded with the throwing head main body, and the outer side of the throwing head main body is wrapped and welded with a wear-resistant alloy layer.

[0007] Preferably, one end of the throwing head main body is fixedly provided with an installation groove, and carbide bars are embedded in the inner side of the installation groove.

[0008] Preferably, urethane sealant is adhesively connected in the gap between the installation groove and the carbide bars, and the bottom end of the steel sleeve is fixedly connected with an installation block.

[0009] Preferably, the surface of the installation block is fixedly provided with threaded holes, the inner side of the steel sleeve is fixedly provided with a fixing groove, and a connecting rod is fixedly welded in the inner side of the fixing groove.

[0010] Compared with the prior art, the beneficial effects of the utility model are as follows:

[0011] By setting the steel sleeve, wear-resistant alloy layer, cemented carbide strip, and urethane sealant, the overall hardness of the throwing head body is improved, and its service life is extended. The urethane sealant is used to fill the gap in the installation groove, further strengthening the connection stability between the throwing head body and the cemented carbide strip. With the steel sleeve set at one end, while ensuring sufficient toughness of the throwing head body, it can prevent the throwing head body from experiencing fatigue wear, making the throwing head body both wear-resistant and impact-resistant.

[0016] The following will clearly and completely describe the technical solutions in the embodiments of the present utility model with reference to the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all of the embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present utility model.

[0017] Please refer to Figures 1-3 , the present utility model provides a technical solution: a throwing head for a mine sand making machine, including a steel sleeve 1. One end of the steel sleeve 1 is provided with a throwing head body 2. The outer side of the throwing head body 2 is provided with a wear-resistant alloy layer 3. One end of the throwing head body 2 is provided with an installation groove 4. The inner side of the installation groove 4 is provided with a cemented carbide strip 5.
