Description

Technical Field

[0001] This utility model belongs to the field of mechanical equipment, specifically the field of dust suppression equipment, and particularly relates to a dust suppression device for feeding a crusher. Background Technology

[0002] In mining operations, the ore being mined is often large in volume and unsuitable for direct beneficiation. Therefore, mining trucks are typically used to transport the ore to a crusher for initial crushing, thus laying the foundation for subsequent ore transport.

[0003] However, dust is inevitably generated during the unloading of ore from the mining truck to the crusher, polluting the working environment. Furthermore, the crusher's crushing efficiency is affected when processing large-sized ore. Therefore, to optimize this process, hydraulic breakers are usually installed around the crusher. Workers first screen out large-sized ore, then use the hydraulic breakers to crush and break them, effectively improving the crusher's processing efficiency. However, the hydraulic breakers also generate dust during operation.

[0004] To combat dust pollution, mist cannons are typically installed around crushers for dust suppression. However, because the large amount of dust generated during crusher operation tends to rise, traditional mist cannon layouts often fail to achieve the desired dust suppression effect, and the working environment is still affected by pollution to some extent. Utility Model Content

[0005] This invention addresses the technical problem of poor dust suppression effect of mist cannons on crushers by providing a dust suppression device for crusher feeding. By adjusting the posture of the telescopic arm and auxiliary support arm and controlling the position of the transfer water tank, damage to the transfer water tank during feeding can be avoided. The transfer water tank is used for dust suppression, and the rotating and diffused water mist coverage area of ​​the transfer water tank improves the dust suppression effect.

[0006] The technical solution adopted by this utility model is as follows: a crusher feeding and dust suppression device is provided, including a water tank, a water pump installed in the water tank, and a water outlet pipe connected to the water outlet of the water pump. A vertical main support arm is installed on the water tank. A secondary support arm and a telescopic component are rotatably hinged on the main support arm, and the telescopic component is rotatably hinged to the secondary support arm. A telescopic arm is fixedly installed on the secondary support arm, and an installation platform is fixedly installed on the telescopic arm. A sleeve is installed on the installation platform, and both ends of the sleeve pass through the installation platform and are rotatably installed with the installation platform by means of a driving component. The top of the sleeve is connected to the water outlet pipe by means of a rotary joint, and a transfer water tank is connected to the bottom of the sleeve. Atomizing nozzles are evenly installed on the side wall and bottom surface of the transfer water tank.

[0007] When the vehicle feeds material into the crusher, the telescopic arm retracts, and the telescopic component drives the auxiliary support arm to rotate along the main support arm to a vertical position. This allows the transfer water tank to be removed from above the crusher to prevent damage from falling rocks. After the material is unloaded, the telescopic component drives the auxiliary support arm to rotate to a vertical position with the main support arm, and the extension of the telescopic arm pushes the transfer water tank above the crusher. Subsequently, the water pump inside the tank operates, pumping water into the transfer water tank, and water mist is sprayed outward from the atomizing nozzles on the transfer water tank, thereby absorbing the dust and causing it to settle. The transfer water tank is mounted on the installation platform with the help of a sleeve. The drive component drives the transfer water tank to rotate, throwing the water mist outward, spreading the coverage area of ​​the water mist and improving dust suppression efficiency. At the same time, the sleeve is connected to the water outlet pipe through a rotary joint, which ensures the smooth rotation of the sleeve.

[0008] To further optimize this technical solution, a base plate is fixedly installed at the bottom of the water tank, the outer side wall of the base plate protrudes from the outer side wall of the water tank, and a through hole is opened on the base plate along the circumferential direction.

[0009] The water tank is placed around the crusher, and anchor bolts are installed on the support surface, passing through the through holes in the bottom plate of the water tank. After being locked with nuts, the stability of the water tank installation is ensured, as well as the stability and safety of the water tank in use.

[0010] To further optimize this technical solution, the telescopic component includes a telescopic cylinder, the cylinder body of which is rotatably hinged to the main support arm or the auxiliary support arm, and the output shaft of the telescopic cylinder is rotatably hinged to the auxiliary support arm or the main support arm.

[0011] The cylinder body of the telescopic cylinder is rotatably hinged to the main support arm (or auxiliary support arm), and the output shaft of the telescopic cylinder is rotatably hinged to the auxiliary support arm (or main support arm). Through the telescopic operation of the telescopic cylinder, the angle of the main support arm and the auxiliary support arm is driven to rotate. The telescopic cylinder has a simple structure and is stable and reliable in use.

[0012] To further optimize this technical solution, the telescopic arm includes a main sleeve and a secondary sleeve that are fitted together. The main sleeve is fixedly installed with the secondary support arm, and the secondary sleeve is fixedly installed with the installation platform. The main sleeve and the secondary sleeve are driven to slide by a linear drive assembly.

[0013] The telescopic boom consists of a main sleeve and a secondary sleeve, which has a simple structure. The main sleeve and the secondary sleeve are driven to slide by a linear drive assembly, ensuring stability during use.

[0014] To further optimize this technical solution, the main sleeve and the auxiliary support arm are inserted together and fixed by means of pins.

[0015] The main sleeve is fixed to the secondary support arm by means of pins, which is simple in structure and stable and secure in use.

[0016] To further optimize this technical solution, the installation platform is provided with a slot, and the installation platform is inserted into the secondary sleeve through the slot and fixed by means of a pin.

[0017] The mounting platform is inserted into the secondary sleeve via a slot and secured with pins, ensuring a firm and stable installation.

[0018] To further optimize this technical solution, the linear drive assembly includes a power structure disposed within the main sleeve, a lead screw coaxially fixedly mounted on the output shaft of the power structure, and a lead screw nut meshing with the lead screw; a connecting block is fixedly sleeved within the secondary sleeve, and the connecting block is installed in conjunction with the lead screw nut.

[0019] The power structure inside the main sleeve drives the lead screw to rotate, which in turn engages the lead nut to move the auxiliary sleeve along the main sleeve. This makes the operation simple, flexible, and reliable.

[0020] To further optimize this technical solution, the driving component includes a drive motor that is fixedly installed on the mounting platform, and the output shaft of the drive motor is driven and mounted to the sleeve via a transmission assembly.

[0021] The drive motor on the mounting platform drives the sleeve to rotate via a transmission assembly, ensuring stable operation.

[0022] To further optimize this technical solution, the transmission assembly includes a matching transmission wheel and a transmission belt, and the transmission wheel is respectively connected to the output shaft of the drive motor and the sleeve.

[0023] The matching drive pulley and drive belt have a simple structure and are flexible and reliable in use.

[0024] The beneficial effects of this utility model are as follows:

[0025] 1. When the vehicle dumps material into the crusher, the telescopic arm retracts and drives the auxiliary support arm to rotate to a vertical position, so that the transfer water tank is removed from above the crusher, which can avoid damage to the transfer water tank. After the material is unloaded, the auxiliary support arm is driven to rotate to the vertical position of the main support arm. At the same time, the telescopic arm extends to push the transfer water tank above the crusher and sprays water mist outward to absorb and sink the dust raised by the unloading.

[0026] 2. The transfer water tank is installed on the installation platform with the help of a sleeve. When the transfer water tank sprays water mist, the drive motor drives the sleeve to rotate through the transmission belt, which in turn makes the transfer water tank rotate. The transfer water tank throws the water mist outward, which expands the coverage area of ​​the water mist and improves the dust suppression efficiency. At the same time, the sleeve is connected to the water outlet pipe through a rotary joint, which ensures the smooth rotation of the sleeve.

[0027] 3. After placing the water tank around the crusher, anchor bolts are installed on the support surface, passing through the through holes in the bottom plate of the water tank, and then tightened with nuts to ensure the stability of the water tank installation and the stability and safety of its use.

[0035] The present invention will now be described in further detail with reference to the accompanying drawings and specific embodiments.

[0036] Please see the appendix Figure 1 Appendix Figure 2The dust suppression equipment for crusher feeding includes a water tank 1 installed around the crusher. A base plate 101 is fixedly installed at the bottom of the water tank 1. The outer side wall of the base plate 101 protrudes from the outer side wall of the water tank 1, and a through hole 1011 is opened on the base plate 101. By pre-fabricating anchor bolts on the support surface, they pass through the through hole 1011 and the nuts are tightened to fix the water tank 1 on the support surface to ensure the firmness of use. A water pump 2 is installed in the water tank 1. A water outlet pipe 201 is connected to the outlet of the water pump 2. After water is injected into the water tank 1, the water pump 2 draws the water flow to produce water mist using atomizing nozzles 801 to absorb and suppress the dust scattered during the crushing operation and feeding operation of the crusher.

[0037] Please see the appendix Figure 1 Appendix Figure 2 A vertical main support arm 3 is installed on the water tank 1. A secondary support arm 4 is rotatably hinged to the main support arm 3. The main support arm 3 and the secondary support arm 4 can rotate at an angle by means of a telescopic component. The telescopic component includes a telescopic cylinder 9. The telescopic cylinder 9 can be a hydraulic telescopic cylinder 9 or a pneumatic telescopic cylinder 9. The cylinder body of the telescopic cylinder 9 is rotatably hinged to the main support arm 3 (or the secondary support arm 4). The output shaft of the telescopic cylinder 9 is rotatably hinged to the secondary support arm 4 (or the main support arm 3). The telescopic operation of the telescopic cylinder 9 drives the main support arm 3 and the secondary support arm 4 to rotate at an angle.

[0038] Please see the appendix Figure 1 Appendix Figure 6 A telescopic arm 5 is fixedly installed on the secondary support arm 4, and an installation platform 6 is fixedly installed on the telescopic arm 5. The telescopic arm 5 includes a main sleeve 501 and a secondary sleeve 502 that are slidably connected. The main sleeve 501 is fixedly installed on the secondary support arm 4, and the secondary sleeve 502 is fixedly installed on the installation platform 6. The main sleeve 501 is inserted into the secondary support arm 4 and fixed by means of a pin 10. The installation platform 6 has a slot 601, which is inserted into the secondary sleeve 502 and can also be fixed by means of a pin 10. The structure is simple and ensures the reliability of use.

[0039] Please see the appendix Figure 5 The main sleeve 501 and the auxiliary sleeve 502 are driven to slide linearly by a linear drive assembly. The linear drive assembly includes a power structure 11 set in the main sleeve 501. The power structure 11 can be a servo motor, etc. A lead screw 12 is coaxially fixedly installed on the output shaft of the power structure 11. A lead screw nut 13 is engaged with the lead screw 12. A connecting block 5021 is fixedly sleeved in the auxiliary sleeve 502. The connecting block 5021 is matched with the lead screw nut 13. After the power structure 11 drives the lead screw 12 to rotate, it engages the lead screw nut 13 and drives the auxiliary sleeve 502 to move linearly in the main sleeve 501, thereby stretching and contracting the telescopic arm 5 and adjusting the position of the installation platform 6.

[0040] Please see the appendix Figure 6A sleeve 7 is installed on the mounting platform 6. Both ends of the sleeve 7 pass through the mounting platform 6 and are rotated and installed with the mounting platform 6 by means of a driving component. The driving component includes a drive motor 14 fixedly installed with the mounting platform 6. The drive motor 14 can be fixedly installed on the top surface of the mounting platform 6. Its output shaft passes through the mounting platform 6 and is driven and installed with the sleeve 7 by means of a transmission assembly. The transmission assembly can be a matching transmission wheel 15 and a transmission belt 16. The transmission wheel 15 is sleeved with the output shaft of the drive motor 14 and the sleeve 7 respectively, thereby driving the sleeve 7 to rotate.

[0041] Please see the appendix Figure 1 Appendix Figure 3 Appendix Figure 6 The top of the sleeve 7 is connected to the outlet pipe 201 via a rotating structure, and the bottom of the sleeve 7 is connected to and installed with a transfer water tank 8. The side walls and bottom surface of the transfer water tank 8 are evenly equipped with atomizing nozzles 801. The water pump 2 draws water from the water tank 1 into the transfer water tank 8 through the sleeve 7 and sprays it out through the atomizing nozzles 801 on the transfer water tank 8. The rotating joint 701 ensures the smooth rotation of the sleeve 7.

[0042] The working principle of the dust suppression equipment for the crusher is as follows: A water tank 1 is placed around the crusher, and anchor bolts are installed on the support surface, passing through the through holes 1011 on the bottom plate 101 of the water tank 1. After tightening with nuts, the stability and safety of the water tank 1 are ensured. When a vehicle dumps material into the crusher, the telescopic arm 5 retracts, and simultaneously, the telescopic cylinder 9 drives the auxiliary support arm 4 to rotate along the main support arm 3 to a vertical position, thereby removing the transfer water tank 8 from above the crusher and effectively avoiding potential damage to the transfer water tank 8 caused by falling rocks. After the material is unloaded, the telescopic cylinder 9 drives the auxiliary support arm 4 to rotate to a vertical position on the main support arm 3. At the same time, the drive motor 14 inside the main sleeve 501 of the telescopic arm 5 operates, causing the lead screw 12 to rotate and engage with the lead nut 13, pushing the auxiliary sleeve 502 to move linearly along the main sleeve 501, thus extending the telescopic arm 5 and pushing the transfer water tank 8 above the crusher. Subsequently, the water pump 2 inside water tank 1 operates, pumping water into the transfer water tank 8, and spraying water mist outward from the atomizing nozzles 801 on the transfer water tank 8, thereby adsorbing the raised dust and causing it to settle. The transfer water tank 8 is mounted on the installation platform 6 via a sleeve 7. When the transfer water tank 8 sprays water mist, the drive motor 14 drives the sleeve 7 to rotate via the transmission belt 16, causing the transfer water tank 8 to rotate. The transfer water tank 8 then throws the water mist outward, expanding the coverage area of ​​the water mist and improving dust suppression efficiency. At the same time, the sleeve 7 is connected to the water outlet pipe 201 via a rotary joint 701, which ensures the smooth rotation of the sleeve 7.
