Description

Technical Field

[0001] The utility model relates to the technical field of shot blasting machines, and particularly relates to a crawler type shot blasting machine for metal heat treatment. Background Art

[0002] The crawler type shot blasting machine for metal heat treatment is a device used to improve the surface quality of metal workpieces, mainly applied in the heat treatment process. It sprays hard shot materials, such as steel shots or iron shots, onto the surface of metal workpieces through a high-speed rotating shot blasting device to remove oxide scales, rust, or other impurities, and form a uniform roughness on the surface. This treatment can not only enhance the surface hardness of the metal, but also improve the effect of subsequent heat treatment and the durability of the material. The working principle of the crawler type shot blasting machine is to place the workpieces on the crawler and send the workpieces into the shot blasting area through the transmission system of the crawler. The shot blasting device inside the equipment shoots the shot materials at high speed to impact the surface of the workpieces. The crawler type design allows continuous and efficient processing of a large number of workpieces, suitable for large-scale production. This equipment is widely used in industries such as machinery manufacturing, automobiles, ships, and construction to ensure the quality and performance of metal components.

[0003] The prior art has the following defects or problems: The prior art with the publication number of: CN213498581U discloses a crawler type shot blasting machine for metal heat treatment, specifically relating to the technical field of shot blasting machines, including a working chamber. One side of the top of the working chamber is detachably installed with a shot and sand separation device. The other side of the top of the working chamber is fixedly installed with a mounting block. The top of the working chamber is detachably installed with a shot blasting device. The top inside the working chamber is communicated with an air extraction pipe. One side of the air extraction pipe is fixedly installed with a mounting plate. One side of the working chamber is detachably installed with a feeding door. The bottom end inside the working chamber is fixedly installed with a fixing rod.

[0004] During the use of the above equipment, by setting the temperature cooperation between the dust removal device and the filtering device, the effect of air purification is achieved, avoiding the need to recycle the shot blasting sand after the shot blasting machine finishes shot blasting. Since a large amount of dust will be generated during the shot blasting process, these dusts will float in the air. Once the dust is directly discharged into the air, it will cause environmental pollution problems, enhancing the practicability of the device.

[0005] In the structure of the shot blasting machine described above, there is no structure for adjusting the throwing speed of the shots during shot blasting, and it cannot be adjusted according to the working requirements. At the same time, it cannot collect and clean the debris generated after shot blasting. Therefore, a crawler type shot blasting machine for metal heat treatment is proposed to address the above deficiencies.
