Description

Technical Field

[0001] This utility model belongs to the field of crusher technology, specifically a structure for preventing blockage at the feed inlet of a crusher. Background Technology

[0002] In modern industrial production, crushers are key equipment in many fields such as ore processing, food manufacturing, and chemical raw material processing, undertaking the important task of crushing and refining materials. However, the feed inlet of traditional crushers is prone to clogging, which seriously restricts production efficiency and equipment stability.

[0003] From a production process perspective, traditional crushers typically employ a simple gravity-feed design, relying on the material's own weight to fall freely into the crushing chamber. However, in actual production, material characteristics are complex and varied. When processing materials with high moisture content and strong viscosity, such as sludge from wastewater treatment or pectin-rich fruit raw materials, the material easily adheres to the inner wall of the feed inlet, forming an accumulation layer and clogging the channel. For materials with uneven particle size, large pieces cannot be crushed in time, getting stuck in the narrow part of the feed inlet, causing subsequent material conveying to be interrupted. Taking the ore processing industry as an example, when processing ores containing clay, the clay becomes more viscous after coming into contact with water, frequently clogging the feed inlet and forcing the crusher to be stopped frequently for cleaning. This reduces the effective operating time of the equipment by more than 30%, resulting in a significant decrease in production capacity.

[0004] Therefore, this utility model provides an anti-clogging structure for the feed inlet of a crusher. Utility Model Content

[0005] In order to overcome the shortcomings of the existing technology and solve at least one of the problems mentioned in the background technology, a clogging prevention structure for the feed inlet of a crusher is proposed.

[0006] The technical solution adopted by this utility model to solve its technical problem is as follows: A pulverizer inlet anti-clogging structure, comprising a base plate; a support leg fixedly installed on the top of the base plate, a pulverizer fixedly installed on the top of the support leg, an inlet fixedly installed on the top of the pulverizer, a dividing mechanism provided on the inner wall of the inlet, scraping components provided on both sides of the inner wall of the inlet; a feeding component provided on the top of the inner wall of the pulverizer, a driving mechanism provided on the side of the pulverizer near the first gear; a transmission mechanism provided on the side of the pulverizer near the first gear; the dividing mechanism includes a first rotating roller, a cone spike, and a first gear; the first rotating roller is rotatably installed in the middle of the bottom of the inner wall of the inlet, the cone spike is fixedly installed on the surface of the first rotating roller, and the first gear is rotatably installed on one side of the inlet, with one side of the first gear fixedly installed to the first rotating roller; the cooperative use of the first rotating roller, the cone spike, and the first gear can initially pulverize the material inside the inlet, allowing larger materials to be broken down, thus enabling them to enter the pulverizer normally without jamming or clogging, ensuring the efficiency of the equipment during use.

[0007] Preferably, the scraping assembly includes a second rotating roller and a scraper. Two sets of the second rotating roller are provided, and the two sets of the second rotating roller are rotatably installed on both sides of the bottom of the feed inlet. The surface of the second rotating roller is fixedly installed with the scraper. In this scheme, the cooperation between the second rotating roller and the scraper can continuously scrape the inner wall of the feed inlet to prevent sticky materials from sticking to the narrow part of the inner wall of the feed inlet and causing blockage. At the same time, it can also work with the cone to crush the material.

[0008] Preferably, the feeding assembly includes a limiting block and a metering wheel. The limiting block is fixedly installed on the top of the inner wall of the crusher, and the metering wheel is rotatably installed on the top of the inner wall of the crusher. The metering wheel is located on the inner wall of the limiting block. In this scheme, the cooperation between the limiting block and the metering wheel can quantitatively convey small pieces of material, prevent too much material from being conveyed into the crusher at the same time and causing blockage, and ensure the normal use of the crusher.

[0009] Preferably, the drive mechanism includes an L-shaped support frame, a motor, and a connecting plate. The L-shaped support frame is fixedly installed on the side of the crusher near the first gear, and the inner wall of the L-shaped support frame away from the crusher is fixedly installed with the motor. The output end of the motor is fixedly installed with the connecting plate. In this scheme, the coordinated use of the L-shaped support frame, the motor, and the connecting plate can provide the main power output for the use of the entire equipment, ensuring that the dividing mechanism, the scraping component, and the feeding component can be used normally.

[0010] Preferably, the transmission mechanism includes a gear ring, a second gear, and a third gear. The gear ring is fixedly installed on the side of the connecting plate away from the motor. Two sets of the second gear are provided, and the two sets of the second gear are rotatably installed on both sides of the crusher near the first gear. The side of the second gear away from the connecting plate is fixedly installed with the second rotating roller. The third gear is fixedly installed on the side of the crusher near the first gear, and the side of the third gear near the crusher is fixedly installed with the metering wheel. The first gear, the second gear, and the third gear all mesh with the gear ring. In this scheme, the coordinated use of the gear ring, the second gear, and the third gear can drive the gear ring to rotate through the driving of the connecting plate, and simultaneously drive the second gear, the third gear, and the first gear to rotate, ensuring that the kinetic energy of the motor can be fully utilized and reducing power waste.

[0011] Preferably, the vibrating motor is fixedly installed on the side of the crusher away from the first gear. In this design, the vibrating motor can make the material fall more smoothly through the vibration it generates, further preventing material blockage and ensuring normal material flow.

[0012] The beneficial effects of this utility model are as follows: 1. The anti-clogging structure for the feed inlet of a crusher described in this utility model, through the arrangement of a first rotating roller, a cone spike, and a first gear, enables the first rotating roller, the cone spike, and the first gear to perform preliminary crushing of the material inside the feed inlet, so that larger materials can be broken down and can enter the crusher normally without jamming or clogging, thus ensuring the efficiency of the equipment during use.

[0013] 2. The anti-clogging structure for the feed inlet of a crusher described in this utility model, through the arrangement of a second rotating roller and a scraper, enables the second rotating roller and the scraper to work together to continuously scrape the inner wall of the feed inlet, preventing sticky materials from sticking to the narrow part of the inner wall of the feed inlet and causing blockage. At the same time, it can also work with the cone to crush the material. Attached Figure Description

The scraping assembly 6 includes a second rotating roller 61 and a scraper 62. Two sets of second rotating rollers 61 are provided, and the two sets of second rotating rollers 61 are rotatably mounted on both sides of the bottom of the feed inlet 4. The surface of the second rotating roller 61 is fixedly mounted to the scraper 62. The feeding assembly 7 includes a limiting block 71 and a metering block. Wheel 72 and limiting block 71 are fixedly installed on the top of the inner wall of the crusher 3. Metering wheel 72 is rotatably installed on the top of the inner wall of the crusher 3. Metering wheel 72 is located on the inner wall of limiting block 71. The drive mechanism 8 includes an L-shaped support frame 81, a motor 82 and a connecting plate 83. The L-shaped support frame 81 is fixedly installed on the side of the crusher 3 near the first gear 53. The inner wall of the L-shaped support frame 81 away from the crusher 3 is fixedly installed with the motor 82. The output end of the motor 82 is fixedly installed with the connecting plate 83. The transmission mechanism 9 includes a gear ring 91, a second gear 92 and a third gear 93. The gear ring 91 is fixedly installed on the top of the inner wall of the crusher 3. On the side of the connecting plate 83 away from the motor 82, there are two sets of second gears 92. The two sets of second gears 92 are rotatably installed on both sides of the crusher 3 near the first gear 53. The side of the second gear 92 away from the connecting plate 83 is fixedly installed with the second rotating roller 61. The third gear 93 is fixedly installed on the side of the crusher 3 near the first gear 53. The side of the third gear 93 near the crusher 3 is fixedly installed with the metering wheel 72. The first gear 53, the second gear 92 and the third gear 93 are all meshed with the gear ring 91. The vibrating motor 100 is fixedly installed on the side of the crusher 3 away from the first gear 53.

[0020] like Figures 1 to 6As shown, the combined use of the first rotating roller 51, the cone spike 52, and the first gear 53 can initially crush the material inside the feed inlet 4, allowing larger materials to be broken down and thus enter the crusher 3 normally without jamming or clogging, ensuring the efficiency of the equipment. The combined use of the second rotating roller 61 and the scraper 62 can continuously scrape the inner wall of the feed inlet 4, preventing sticky materials from adhering to the narrow part of the inner wall of the feed inlet 4 and causing blockage. At the same time, it can also work with the cone spike 52 to crush the material. The combined use of the limiting block 71 and the metering wheel 72 can quantitatively convey small pieces of material, preventing too much material from being conveyed into the crusher 3 at the same time and causing blockage, ensuring the efficiency of the equipment. To ensure the normal operation of the crusher 3, the L-shaped support frame 81, motor 82, and connecting plate 83 work together to provide the main power output for the entire equipment, ensuring the normal operation of the dividing mechanism 5, scraping assembly 6, and feeding assembly 7. The gear ring 91, second gear 92, and third gear 93 work together to drive the gear ring 91 to rotate through the connecting plate 83, and simultaneously drive the second gear 92, third gear 93, and first gear 53 to rotate, ensuring that the kinetic energy of the motor 82 is fully utilized and reducing power waste. The vibrating motor 100 can make the material fall more smoothly through the vibration it generates, further preventing material blockage and ensuring normal material flow.

[0021] Working principle: During operation, the base plate 1 is first placed on a flat surface. Then, the motor 82 is started to drive the connecting plate 83 to rotate. The rotation of the connecting plate 83 drives the gear ring 91 to rotate. The rotation of the gear ring 91 simultaneously drives the second gear 92, the third gear 93, and the first gear 53 to rotate. When the first gear 53 rotates, it causes the first rotating roller 51 to drive the cone 52 to rotate. When the second gear 92 rotates, it drives the second rotating roller 61 and the scraper 62 to rotate. When the third gear 93 rotates, it drives the metering wheel 72 to rotate. Then, the user pours the material into the feed inlet 4. After the material enters the feed inlet 4, it is separated by the cone 52, allowing the material to be... The cone 52 scrapes a hole to allow larger materials to be crushed. The crushed material then falls onto the top of the metering wheel 72. As the metering wheel 72 rotates, it conveys the material into the crusher 3. At the same time, the scraper 62 continuously scrapes the surface of the feed inlet 4 during feeding. This not only helps to crush the material in conjunction with the cone 52 but also prevents the material from sticking to the inner wall of the feed inlet 4 and causing blockage. During feeding, the user can start the vibration motor 100 to make it vibrate, which makes the material fall faster. The vibration also causes the cone 52 to continuously pierce the material with its spikes, making it more pulverized and reducing the crushing pressure of the crusher 3.
