[0022] Compared with the prior art, the beneficial effects of the utility model are:

[0023] 1. The utility model adopts the arrangement of sound insulation cotton, sound insulation and noise reduction structure, glass wool, sound insulation board and high-density foam material in the noise reduction and soundproofing cover. The sound insulation cotton is a porous material that can effectively absorb sound waves and reduce the propagation of sound. In the drum shot blasting machine, the sound insulation cotton is usually placed inside the outer shell of the equipment or near the key noise source. By absorbing noise, the sound insulation cotton can significantly reduce the noise level of the equipment during operation and provide a quieter working environment for the operator. At the same time, reducing noise also helps to reduce noise pollution to the surrounding environment; glass wool is a porous material made of glass fiber with excellent sound absorption performance. Glass wool not only has good sound absorption performance, but also has high fire resistance. Glass wool also has good weather resistance and stability, and can maintain its performance for a long time; the honeycomb-arranged sound insulation and noise reduction structure can effectively reflect and scatter sound waves, thereby reducing the direct propagation of sound waves to the external environment. When sound waves propagate in the honeycomb structure, due to the complex structure and diverse sound wave paths, the sound wave energy will be dissipated during multiple reflections and refractions, thereby reducing the noise intensity. The cavity in the honeycomb structure can effectively absorb sound, especially medium and high frequency sounds, thereby further reducing the noise level. The honeycomb-arranged sound insulation and noise reduction structure can effectively reduce the noise generated by equipment such as drum shot blasting machines, providing operators with a quieter working environment, while reducing the interference of noise to the surrounding environment. Reducing the noise level can significantly improve the working environment of operators, reduce the potential harm of noise to personnel health, and improve work satisfaction and production efficiency; sound insulation board is a board specially used for sound insulation, usually made of high-density material, and the sound insulation board reduces the propagation of noise by reflecting sound waves. The sound insulation board can effectively block the propagation of sound waves, thereby reducing the noise level outside the equipment. At the same time, the sound insulation board also has high strength and durability, and can withstand the vibration and impact generated by the operation of the equipment; high-density foam material is a lightweight porous material with excellent sound insulation and shock absorption performance. In the drum shot blasting machine. By absorbing sound waves and reducing vibration, high-density foam materials can significantly reduce the noise level during the operation of the equipment. At the same time, due to its lightweight characteristics, high-density foam materials will not have a significant impact on the overall weight of the equipment. In addition, high-density foam materials also have good weather resistance and stability, and can maintain their performance for a long time. BRIEF DESCRIPTION OF THE DRAWINGS

[0049] See also Figure 6A drum structure 21 is arranged inside the drum shot blasting machine body 2, and the drum structure 21 is inlaid and connected with the drum shot blasting machine body 2. The drum structure 21 is divided into an inner drum and an outer drum, and the inner drum is inlaid in the outer drum. A waste chip groove 22 is arranged inside the drum body of the drum shot blasting machine body 2, and the waste chip groove 22 is integrally formed with the inside of the drum body of the drum shot blasting machine body 2. The waste chip groove 22 is connected to the pipe of the shot blasting recovery device 12 extending into the drum shot blasting machine body 2. The drum structure 21 is the core part of the drum shot blasting machine, which is used to load and rotate the workpiece so that the surface of the workpiece is evenly shot blasted. The waste chip groove 22 is used to collect waste chips and impurities generated during the shot blasting process, keep the inside of the drum clean, and facilitate subsequent cleaning and treatment.

[0050] Working principle: When in use, the drum structure 21 in the drum shot blasting machine body 2 is composed of an inner and outer drum. The inner drum is embedded in the outer drum. The drum cover 9 is connected to the drum shot blasting machine body 2 by a connecting hinge, which is convenient for opening and closing the drum and loading and unloading of workpieces. The workpiece is placed in the drum and driven by the driving device through the driving transmission structure 11 to rotate. The drum structure 21 starts to rotate, causing the workpiece to continuously roll in the drum, thereby ensuring that the surface of the workpiece is evenly shot blasted. Initially, the shot is thrown into the bucket-shaped box on the top of the shot blasting lifting and processing device 3, and then the shot blasting lifting and processing device 3 ejects the shot from the shot blasting box and throws the shot blasting material into the drum through the shot blasting channel pipe 31. During the rotation of the drum, the shot blasting material hits the surface of the workpiece at high speed, removes impurities such as rust and oxide layer on the surface of the workpiece, and strengthens the surface of the workpiece. After the shot blasting acts on the workpiece, the mixture of debris and shot blasting is shaken left and right by the two-way drive motor 8, so that the mixture is gathered in the waste chip trough 22 in the drum shot blasting machine body 2, and then the mixture is sucked into the shot blasting recovery device 12, and then the shot blasting recovery device 12 sends the mixture to the shot blasting pretreatment structure 13 through a pipeline. In the pretreatment structure, the screening mesh structure 1311 on the partition screen plate 131 performs preliminary screening on the mixture to remove impurities and oversized particles therein, and the screened mixture enters the shot blasting lifting treatment device 3, and then flows into the separation conveying spiral after entering the shot blasting lifting treatment device 3. During this period, the debris in the mixture, such as oxide skin, broken shot, complete shot, dust, etc., begins to be further separated. The spiral will evenly distribute the mixture along the separator, thereby forming a full flow curtain state, preparing for the next sorting stage. After entering the sorting stage, the dust collector fan starts to exhaust air through the exhaust holes. Effectively separate the complete shot and scale fragments, broken shot, and dust. After separation, the waste flows out from the separator shot overflow port, while the fine shot and dust flow out from the waste port. The complete shot will be collected into the shot bin for reuse. During the operation of the drum shot blasting machine 1, the machine will make a loud noise, and the staff working in this environment for a long time will have an impact on their health. The noise reduction and sound insulation cover 5 effectively reduces the noise generated by the drum shot blasting machine 1 during operation through its internal sound insulation cotton 52, sound insulation and noise reduction structure 53, glass wool 54, sound insulation board 55 and high-density foam material 56 and other multi-layer sound insulation materials. This not only protects the hearing of the operator, but also reduces the interference of noise to the surrounding environment.
