Technical Field

[0001] This utility model belongs to the technical field of waste steel recycling equipment, specifically relating to a dust removal device for a steel waste crusher. Background Technology

[0002] Steel scrap shredders are devices used to process scrap steel, aiming to break it into smaller particles for subsequent processing and recycling. This scrap steel mainly includes end-of-life vehicles, household appliances, and construction waste. Processing these materials with a shredder produces a large amount of fine metal particles, dust, and other minute substances.

[0003] Patent publication number CN211514779U discloses a steel crusher, including an internal cutting mechanism, a crusher frame, and a bottom elastic shock-absorbing structure. The cutting mechanism includes two cutting wheels with cutting blades on their surfaces, and support rods at the ends of the bearings of the two cutting wheels. The crusher frame includes a feed inlet slide plate, a feed inlet slide plate support rod, an anti-rebound plate, a shock-absorbing layer, and an outer steel plate layer. The bottom elastic shock-absorbing structure comprises three components: an upper support plate, a lower support plate, and a middle spring vibration isolator. This patent is designed based on the concept of vibration reduction and noise reduction. The bottom shock-absorbing structure, together with the internal shock-absorbing layer of the crusher, significantly reduces the noise during machine operation. At the same time, the cutting blades on the cutting wheels can be matched to each other, cutting scrap steel into smaller pieces.

[0004] However, the current steel crusher has the following problems: when the device is crushing, the large amount of waste material accumulates, causing the crushing device to stop and jam. Therefore, we propose a dust removal device for steel waste crusher. Utility Model Content

[0005] The purpose of this utility model is to provide a dust removal device for a steel scrap crusher, which can solve the problem in related technologies where the crushing device stops and jams due to the large accumulation of waste material during crushing operations.

[0006] The specific technical solution adopted by this utility model is as follows:

[0007] A dust removal device for a steel scrap crusher includes a fixed frame, a crushing chamber fixedly connected to the top of the fixed frame, a crushing component arranged on the side of the crushing chamber, a material distribution device arranged on the top of the crushing chamber, the material distribution device including a material distribution cylinder, the bottom of the material distribution cylinder fixedly connected to the top of the crushing chamber, a batching component arranged on the top of the material distribution cylinder, and a feeding trough fixedly connected to the moving end of the batching component.

[0008] The crushing assembly includes a high-speed motor, the side of which is fixedly connected to the side of the crushing chamber. The output shaft of the high-speed motor is fixedly connected to a forward roller. A linkage gear is fixedly connected to the side of the forward roller away from the high-speed motor. A reverse roller is rotatably connected to the inner wall of the crushing chamber. A follow-rotation gear is fixedly connected to the side of the reverse roller away from the high-speed motor. The linkage gear and the follow-rotation gear mesh with each other.

[0009] The batching component includes a feeding cover, the bottom of which is fixedly connected to the top of the distributing cylinder. A drive motor is fixedly connected to the top of the feeding cover, and a central rotating shaft is fixedly connected to the output shaft of the drive motor. A scraper is fixedly connected to the circumferential surface of the central rotating shaft. A limiting disc is fixedly connected to the inner wall of the distributing cylinder. The top of the feeding trough is through and fixedly installed on the circumferential surface of the central rotating shaft. A fixing buckle is fixedly connected to the outer wall of the distributing cylinder. A feeding groove is opened on the top of the feeding cover. The central rotating shaft is the moving end of the batching component.

[0010] The top of the limiting plate is in contact with the bottom of the feeding trough, and the outer wall of the scraper is in contact with the inner wall of the distributing cylinder.

[0011] The bottom of the limiting disc is provided with a grinding aid device, which includes a telescopic rod. The fixed end of the telescopic rod is fixedly connected to the bottom of the limiting disc, and the telescopic end of the telescopic rod is fixedly connected to a pressure plate. The top of the pressure plate is provided with a transverse groove, and the top of the pressure plate is fixedly connected to a hanger. The top of the hanger is threadedly connected to a reciprocating screw, and the top of the reciprocating screw is fixedly connected to the bottom of the central rotating shaft.

[0012] A gap is provided between the bottom of the pressing plate and the outer wall of the forward rolling roller, a gap is provided between the bottom of the pressing plate and the outer wall assembly of the reverse rolling roller, and a gap is provided between the outer wall of the pressing plate and the inner wall of the crushing chamber.

[0013] The technical effects achieved by this utility model are as follows:

[0014] This utility model, through the setting of a material distribution device, enables the material distribution cylinder, feeding cover, drive motor, central rotating shaft, scraper, limiting plate, feeding trough, fixing buckle, and feeding trough to cooperate. When the scraper rotates, it scrapes and spreads the waste material. When the notch of the feeding trough aligns with the notch of the limiting plate during the rotation process, the waste material flows from the notch of the feeding trough and the limiting plate to the crushing chamber. This avoids the crushing device from stopping and jamming due to the large accumulation of waste material during crushing.

[0015] This utility model, through the setting of the grinding aid device, enables the telescopic rod, the pressing plate, the cross groove, the hanger, and the reciprocating screw to work together. The up-and-down movement of the hanger drives the pressing plate to move up and down repeatedly under the restriction of the telescopic rod, so that the pressing plate can repeatedly push and press the waste in the crushing chamber, ensuring that the waste can be fully crushed during the crushing process, and reducing the range of debris splashing during the crushing process.

[0023] To make the objectives and advantages of this utility model clearer, the following detailed description is provided in conjunction with embodiments. It should be understood that the following text is merely used to describe one or more specific embodiments of this utility model and does not strictly limit the scope of protection specifically claimed by this utility model.

[0024] like Figure 1-5As shown, a dust removal device for a steel scrap crusher includes a fixed frame 1. A crushing chamber 2 is fixedly connected to the top of the fixed frame 1. A crushing component is provided on the side of the crushing chamber 2. A material distribution device 8 is provided on the top of the crushing chamber 2. The material distribution device 8 includes a material distribution cylinder 81. The bottom of the material distribution cylinder 81 is fixedly connected to the top of the crushing chamber 2. A batching component is provided on the top of the material distribution cylinder 81. A feeding trough 87 is fixedly connected to the moving end of the batching component. The feeding trough 87 can effectively control the feeding amount.

[0025] The crushing assembly includes a high-speed motor 3, which is fixedly connected to the side of the crushing chamber 2. The output shaft of the high-speed motor 3 is fixedly connected to a positive roller 4. A linkage gear 5 is fixedly connected to the side of the positive roller 4 away from the high-speed motor 3. A reverse roller 6 is rotatably connected to the inner wall of the crushing chamber 2. A follow-rotating gear 7 is fixedly connected to the side of the reverse roller 6 away from the high-speed motor 3. The linkage gear 5 and the follow-rotating gear 7 mesh with each other. This is existing technology and will not be further elaborated.

[0026] The batching component includes a feeding cover 82, the bottom of which is fixedly connected to the top of the distributing cylinder 81. A drive motor 83 is fixedly connected to the top of the feeding cover 82. A central rotating shaft 84 is fixedly connected to the output shaft of the drive motor 83. A scraper 85 is fixedly connected to the circumferential surface of the central rotating shaft 84. A limiting disc 86 is fixedly connected to the inner wall of the distributing cylinder 81. The top of the feeding trough 87 passes through and is fixedly installed on the circumferential surface of the central rotating shaft 84. A fixing buckle 88 is fixedly connected to the outer wall of the distributing cylinder 81. A feeding groove 89 is opened on the top of the feeding cover 82. The central rotating shaft 84 is set as the moving end of the batching component to ensure stable operation of the device.

[0027] The top of the limiting plate 86 contacts the bottom of the discharge trough 87, and the outer wall of the scraper 85 contacts the inner wall of the distribution cylinder 81. The necessary contact can reduce the adhesion of waste material in the distribution cylinder 81.

[0028] According to the above structure, when the device is in crushing operation, the operator manually turns on the drive motor 83. The output shaft of the drive motor 83 rotates, which drives the central rotating shaft 84 to rotate. The rotation of the central rotating shaft 84 drives the scraper 85 and the discharge trough 87 to rotate. When the operator pours the steel scrap into the distribution cylinder 81 from the feed trough 89, the scraper 85 scrapes and spreads the scrap flat under rotation. When the discharge trough 87 aligns its notch with the notch of the limiting plate 86 during rotation, the scrap flows from the notch of the discharge trough 87 and the notch of the limiting plate 86 into the crushing chamber 2, thus preventing the crushing device from stopping and jamming due to the large accumulation of scrap during crushing operation.

[0029] like Figure 1-5As shown, a grinding aid device 9 is provided at the bottom of the limiting material plate 86. The grinding aid device 9 includes a telescopic rod 91. The fixed end of the telescopic rod 91 is fixedly connected to the bottom of the limiting material plate 86. The telescopic end of the telescopic rod 91 is fixedly connected to a pressure plate 92. A transverse groove 93 is provided on the top of the pressure plate 92. A hanger 94 is fixedly connected to the top of the pressure plate 92. A reciprocating screw 95 is threadedly connected to the top of the hanger 94. The top of the reciprocating screw 95 is fixedly connected to the bottom of the central rotating shaft 84. The basic structural cooperation ensures the stable operation of the device.

[0030] A gap is provided between the bottom of the pressing plate 92 and the outer wall of the positive roller 4, a gap is provided between the bottom of the pressing plate 92 and the outer wall assembly of the reverse roller 6, and a gap is provided between the outer wall of the pressing plate 92 and the inner wall of the crushing chamber 2 to prevent motion interference during the operation of the device.

[0031] According to the above structure, the rotation of the central shaft 84 drives the reciprocating screw 95 to rotate, and the rotation of the reciprocating screw 95 drives the hanger 94 to move up and down in a threaded motion. The up and down movement of the hanger 94 drives the pressure plate 92 to move up and down repeatedly under the restriction of the telescopic rod 91, so that the pressure plate 92 can repeatedly push and press the waste in the crushing chamber 2, ensuring that the waste can be fully crushed during the crushing process, and reducing the range of debris splashing during the crushing process.

[0032] The above description is merely a preferred embodiment of this utility model. It should be noted that those skilled in the art can make various improvements and modifications without departing from the principle of this utility model, and these improvements and modifications should also be considered within the scope of protection of this utility model. Structures, devices, and operating methods not specifically described or explained in this utility model, unless otherwise specified or limited, shall be implemented using conventional methods in the field.
