Description

Technical Field

[0001] The utility model relates to the technical field of crushers, in particular to a crusher with a dust reduction structure. Background Technique

[0002] Coal mining refers to the process of separating and transporting valuable coal from underground or the surface. The mining methods are mainly divided into two categories: open-pit mining and underground mining. A crusher is a mechanical device that crushes large-sized solid raw materials into required sizes. According to the use scenarios and requirements, crushers can be divided into various types, such as hammer mills, roller mills, claw mills, etc., and crushers are widely used in multiple fields such as mines, building materials, environmental protection, resource recovery, and chemical industries.

[0003] When it is necessary to assist in crushing the mined ore through a crusher, the ore is first poured into the crusher through the opening at the top of the crusher. Then, the motor chamber drives the crushing roller A and the crushing roller B to rotate. At this time, a relative rotation mechanism is formed between the crushing roller A and the crushing roller B, and then the large-volume ore is broken into a smaller state. After that, it is exported from the crushing box through the outlet. However, during the process of the crusher crushing the ore, a large amount of dust will inevitably be scattered around, resulting in a relatively high dust concentration in the area around the crusher. And if the dust is inhaled into the lungs by the staff, it will endanger their physical health, thus affecting the use of the crusher. Content of the Utility Model

[0004] The purpose of the utility model is to provide a crusher with a dust reduction structure to solve the problems raised in the above background technique.

[0005] To achieve the above purpose, the utility model provides the following technical solution: A crusher with a dust reduction structure, including a crushing box, a crushing roller A, and a crushing roller B. The top end of the inner wall of the crushing box is connected with the crushing roller A, and one side of the inner wall of the crushing box close to the crushing roller A is connected with the crushing roller B. And the top end of the outer wall of the crushing box is welded with a support platform. A dust reduction mechanism is arranged on the outer wall of the support platform, and the dust reduction mechanism includes a high-pressure water pump, a water supply pipeline, an output pipeline, an atomizing nozzle, a double-shaft motor, a rotating column, an eccentric plate, a sieve plate, a fixed seat, a spring, a turntable, a guiding seat, a transmission seat, a fixing plate, a rack, and a gear. The high-pressure water pump is installed in the middle of the top end of the support platform, and the top end of the high-pressure water pump is butted with the water supply pipeline. And the bottom end of the water supply pipeline is connected with the output pipeline through a jet hose. The atomizing nozzle is connected to the outer wall of the output pipeline. The double-shaft motor is installed at the bottom end of the outer wall of the crushing box. One output end of the double-shaft motor is butted with the rotating column, and the other output end of the double-shaft motor is butted with the turntable. The eccentric plate is sleeved in the middle of the outer wall of the rotating column. The sieve plate is arranged below the crushing roller A.

[0010] Preferably, the inside of the gear is connected to an output pipe, and the top of the fixing plate is welded to a support platform.

[0011] Compared with the prior art, the beneficial effects of the present utility model are as follows: When the crusher with a dust reduction structure is in use, the atomizing nozzle sprays the water flow in an atomized manner through the dust reduction mechanism, thereby reducing the dust concentration in the surrounding area of the crusher. And starting the double-shaft motor causes the sieve plate to repeatedly collide with the fixed seat, and then shakes off the ore blocking the sieve plate, preventing it from blocking the sieve holes of the sieve plate and affecting the screening work.

Detailed implementation mode

[0019] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without making creative efforts belong to the protection scope of the present invention.

[0020] Please refer to Figures 1-6 , the present invention provides a technical solution: a pulverizer with a dust reduction structure, including a pulverizing box 1, a pulverizing roller A 2 and a pulverizing roller B 3. The top end of the inner wall of the pulverizing box 1 is connected with the pulverizing roller A 2, and the side of the inner wall of the pulverizing box 1 close to the pulverizing roller A 2 is connected with the pulverizing roller B 3. And a support platform 4 is welded to the top end of the outer wall of the pulverizing box 1. A dust reduction mechanism 5 is arranged on the outer wall of the support platform 4. The dust reduction mechanism 5 includes a high-pressure water pump 501, a water supply pipe 502, an output pipe 503, an atomizing nozzle 504, a double-shaft motor 505, a rotating column 506, an eccentric plate 507, a sieve plate 508, a fixed seat 509, a spring 510, a turntable 511, a guiding seat 512, a transmission seat 513, a fixing plate 514, a rack 515 and a gear 516. The middle part of the top end of the support platform 4 is installed with a high-pressure water pump 501, and the top end of the high-pressure water pump 501 is butted with a water supply pipe 502. And the bottom end of the water supply pipe 502 is connected with an output pipe 503 through a jet hose. The outer wall of the output pipe 503 is connected with an atomizing nozzle 504. A double-shaft motor 505 is installed at the bottom end of the outer wall of the pulverizing box 1. And one output end of the double-shaft motor 505 is butted with a rotating column 506, and the other output end of the double-shaft motor 505 is butted with a turntable 511. The middle part of the outer wall of the rotating column 506 is sleeved with an eccentric plate 507. A sieve plate 508 is arranged below the pulverizing roller A 2; a fixed seat 509 is slidably connected inside the sieve plate 508, and a spring 510 is connected inside the fixed seat 509; one side of the outer wall of the fixed seat 509 is welded to the pulverizing box 1. One side of the outer wall of the turntable 511 is connected with a guiding seat 512 through a transmission pin; a transmission seat 513 is welded to the top end of the guiding seat 512, and a fixing plate 514 is slidably connected inside the transmission seat 513; a rack 515 is welded to the top end of the transmission seat 513, and a gear 516 is meshed with the outer wall of the rack 515; the inside of the gear 516 is connected with the output pipe 503, and the top end of the fixing plate 514 is welded to the support platform 4; the atomizing nozzles 504 are evenly distributed on the output pipe 503. The two sides of the outer wall of the output pipe 503 are rotatably connected with the support platform 4. An elastic telescopic mechanism is formed between the sieve plate 508, the fixed seat 509 and the spring 510. The side of the rotating column 506 away from the double-shaft motor 505 is connected with the pulverizing box 1 through a bearing seat. Sieve holes are formed inside the sieve plate 508.

[0021] During specific implementation, during the process of crushing ore by the crusher, in order to reduce the dust concentration in the air, first, water flow is introduced into the high-pressure water pump 501 through the water supply pipeline 502, then the high-pressure water pump 501 is started to direct the water flow to the output pipeline 503, and then the water flow is atomized and sprayed out through the atomizing nozzle 504. At this time, the water mist contacts the dust in the air for dust reduction, thereby reducing the dust concentration in the area around the crusher;

[0022] After the crushed ore contacts the sieve plate 508, the sieve plate 508 is used to screen the ore to prevent the ore that does not meet the requirements from flowing into the next process. Since one output end of the double-shaft motor 505 is connected to the rotating column 506, when the double-shaft motor 505 is started, it drives the rotating column 506 to rotate. The rotation of the rotating column 506 drives the eccentric plate 507 to rotate. Then, when the side of the eccentric plate 507 away from the rotating column 506 contacts the sieve plate 508, an upward thrust will be generated on the sieve plate 508, causing the sieve plate 508 to move upward along the fixed seat 509. When the sieve plate 508 moves upward, it squeezes the spring 510, causing it to deform. After that, when the eccentric plate 507 is disengaged from the sieve plate 508, the spring 510 resets, causing the sieve plate 508 to repeatedly collide with the fixed seat 509, thereby shaking off the ore blocking the sieve plate 508 and preventing it from blocking the sieve holes of the sieve plate 508 and affecting the screening work;

[0023] Since the other output end of the double-shaft motor 505 is connected to the turntable 511, when the double-shaft motor 505 is started to make the sieve plate 508 vibrate repeatedly, it will drive the turntable 511 to rotate together. And because the turntable 511 is connected with the guide seat 512 through a transmission pin, the rotation of the turntable 511 will generate a thrust on the guide seat 512 to make it move up and down reciprocally. And because the guide seat 512 is connected to the transmission seat 513, the movement of the guide seat 512 drives the transmission seat 513 to move together. Then, when the transmission seat 513 moves upward, it drives the rack 515 to move together. Since the transmission seat 513 is slidably connected to the fixing plate 514, at this time, the movement of the transmission seat 513 is guided by the fixing plate 514. And because the rack 515 is meshed with the gear 516, the movement of the rack 515 drives the gear 516 to rotate. And because the gear 516 is connected to the output pipeline 503 on the support table 4, the rotation of the gear 516 drives the output pipeline 503 to rotate together, thereby making the output pipeline 503 drive the atomizing nozzle 504 to swing reciprocally, and then increasing the spraying range of the water mist of the atomizing nozzle 504 and improving the dust reduction effect. Thus, when the crusher is in use, it plays a role in facilitating dust reduction and preventing the sieve plate 508 from being blocked.

[0024] In summary, when the crusher with a dust reduction structure is in use, first pour the ore into it through the opening at the top of the crusher. Then drive the crushing roller A2 and the crushing roller B3 to rotate through the motor compartment. At this time, a relative rotation mechanism is formed between the crushing roller A2 and the crushing roller B3, thereby crushing the large-volume ore into a smaller state. After that, export it from the crushing box 1 through the outlet. This is the prior art and will not be elaborated here. The atomizing nozzle 504 sprays the water in an atomized manner through the dust reduction mechanism 5. Then start the double-shaft motor 505 to make the sieve plate 508 repeatedly collide with the fixed seat 509, thereby shaking off the ore blocking the sieve plate 508 to prevent it from blocking the sieve holes of the sieve plate 508 and affecting the screening work. And when the sieve plate 508 vibrates, the atomizing nozzle 504 also swings reciprocally, thereby increasing the spraying range of the water mist of the atomizing nozzle 504 and improving the dust reduction effect, effectively reducing the dust concentration in the surrounding area of the crusher and improving the dust reduction effect. The content not described in detail in this specification belongs to the prior art well known to those skilled in the art.

Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present invention shall be included in the protection scope of the present invention.
