[0023] The present invention provides a mining scraper tensioning crawler device. Figure 1-4 As shown, the tensioning crawler device of the mining slag scraper includes: a multi-point moving wheel 2 provided on the driving head 1; a mounting frame 3 installed on the driving head 1, and the mounting frame 3 is used to shovel slag; a support roller 4 rotatably installed on the mounting frame 3, and the outer movable sleeve of the support roller 4 is provided with a conveyor belt 5 for conveying slag; a motor 6 fixed on the mounting frame 3, and the output shaft of the motor 6 is fixedly connected to the support roller 4; an excavation head 8 provided on the driving head 1 for scraping slag; a dust reduction component provided on the driving head 1 for processing slag dust; and an adjustment component installed on the mounting frame 3 for adjusting the tension of the conveyor belt 5.
[0024] In this embodiment, the driving head 1 serves as the power and mobile core of the entire slag scraper. The driving head 1 not only assists the slag scraper to flexibly transfer between different positions, but also carries other key components. The multi-point moving wheels 2 installed thereon enhance maneuverability and ensure stable movement in a complex mining environment. The mounting frame 3 is the main supporting structure for shoveling and transporting slag. The support roller 4 serves as the driving shaft of the conveyor belt 5. The conveyor belt 5 is the direct medium for slag transportation. The motor 6 provides power to the support roller 4 to drive the conveyor belt 5 to operate. The excavating head 8 is used for directly excavating and collecting slag and is the front-end tool for slag scraping operations. The dust reduction component is used to deal with the dust generated during the slag transportation process, improve the working environment, and protect the health of operators. The adjustment component can flexibly adjust the tension of the conveyor belt 5, effectively avoiding the problem of loosening of the conveyor belt 5 due to long-term use, thereby ensuring that the slag scraper can continuously and stably transport slag.
[0025] In a further preferred embodiment of the present invention, the dust reduction component includes a water tank 11 installed on the driving vehicle head 1 for storing clean water; a water pump 12 fixed on the driving vehicle head 1, and the liquid inlet end of the water pump 12 extends into the water tank 11; a drain pipe 9 installed at the discharge end of the water pump 12, and the drain pipe 9 is fixed on the mounting frame 3; and a plurality of spray heads 10 arranged on the drain pipe 9 for atomizing clean water.
[0026] In this embodiment, the water tank 11 is a key part of the dust reduction component, providing water for the entire spray dust reduction system. The water pump 12 is the power source of the dust reduction component, responsible for pumping out clean water and pressurizing it to the spray system. The drain pipe 9 serves as a pipeline connecting the water pump 12 and the spray head 10 to ensure that clean water can be smoothly and stably transmitted to each spray point. The spray head 10 is used to atomize the clean water into fine water mist particles and spray them into the slag conveying area, effectively suppressing the dust generated during the slag conveying process. The number and layout of the spray heads 10 need to be adjusted according to the actual situation of the mine and the dust reduction needs.
[0027] In a further preferred embodiment of the present invention, the adjustment assembly includes two limit slots 14 arranged on the mounting frame 3, and a mounting plate 15 is slidably installed in each of the two limit slots 14; an adjustment shaft 13 is rotatably installed between the two mounting plates 15, and the adjustment shaft 13 is in contact with the conveyor belt 5; a clamping plate 16 is respectively fixed on the two mounting plates 15, and a fixing plate 18 is clamped in each of the two clamping plates 16; a plurality of cylinders 17 fixed on the mounting frame 3, and the output rods of the plurality of cylinders 17 are respectively fixedly connected to the two fixing plates 18.
[0028] In this embodiment, the limit groove 14 provides a stable sliding track for the mounting plate 15, preventing deviation and shaking, thereby ensuring the accuracy and reliability of the adjustment. The mounting plate 15, as the main part of the adjustment component, carries key components such as the adjustment shaft 13 and the fixed plate 18, and is the direct executor of the track tensioning adjustment. The adjustment shaft 13 changes the degree of compression on the conveyor track 5 by adjusting its position between the mounting plates 15, thereby achieving track tensioning adjustment to ensure stability and reliability for long-term use. The design of the clamping plate 16 provides a stable installation position for the fixed plate 18, and allows the fixed plate 18 to move under the push of the cylinder 17, thereby driving the mounting plate 15 and the adjusting shaft 13 to move together to achieve track tensioning adjustment.
[0029] In a further preferred embodiment of the present invention, pressure sensors are installed on the top of the two fixing plates 18, and rubber protective sleeves are fixed on the outside of the two pressure sensors. The two clamping plates 16 can contact the two pressure sensors respectively, and an engine is installed in the driving vehicle head 1.
[0030] In this embodiment, the pressure sensor can monitor the pressure changes on the fixed plate 18 in real time, thereby indirectly reflecting the tensioning state of the transmission track 5. By connecting to the control system, the pressure sensor can convert the detected pressure signal into an electrical signal and transmit it to the control system for processing and feedback. This design enables the equipment to automatically adjust the tension of the track to maintain the best working state, thereby improving the intelligence level and automation level of the equipment. The main function of the rubber protective cover is to protect the pressure sensor from external impact and damage and extend its service life. At the same time, the rubber material has good elasticity and wear resistance, and can buffer and disperse the pressure transmitted from the fixed plate 18 to a certain extent, thereby improving the measurement accuracy and stability of the sensor. The engine serves as the power source of the entire equipment and provides the required power support for each component.
[0031] In a further preferred embodiment of the present invention, a plurality of limit blocks are installed on the surface of the conveying crawler 5, and the two supporting rollers 4 and the adjusting shaft 13 are fixedly covered with anti-slip sleeves.
[0032] In this embodiment, the main function of the limit baffle is to limit the movement range of the slag on the conveyor belt 5, which can ensure that the slag can be transported on the belt stably and orderly, thereby improving the conveying efficiency and stability. The anti-slip sleeve is made of a material with a high friction coefficient, which can increase the friction between the support roller 4 and the adjusting shaft 13 and the conveyor belt 5, and prevent the belt from loosening or deflecting due to sliding or slipping during operation. The anti-slip sleeve reduces the direct wear between the support roller 4 and the adjusting shaft 13 and the belt, reduces the replacement frequency of these components, and extends the service life of the equipment.
[0033] In a further preferred embodiment of the present invention, the drain pipe 9 is provided with multiple threaded openings, and multiple spray heads 10 are installed with threaded connectors, and multiple threaded connectors are respectively threadedly installed in the multiple threaded openings. The top of the water tank 11 is provided with a liquid inlet for replenishing clean water, and a block is detachably installed in the liquid inlet.
[0034] In this embodiment, the threaded port provides a convenient interface for the installation of the spray head 10, so that the spray head 10 can be firmly fixed on the drain pipe 9 and is not easy to fall off or loosen. The threaded connection method also facilitates the disassembly and replacement of the spray head 10, and facilitates subsequent maintenance and servicing work. The rehydration port is used to add clean water to the water tank 11 to ensure that the dust reduction component can work continuously and stably. The block is used to seal the rehydration port when rehydration is not required to prevent external pollutants such as dust and impurities from entering the water tank 11.
[0035] In a further preferred embodiment of the present invention, an adjustment plate 7 is fixed on the mounting frame 3 , and a silicone scraper is installed on the adjustment plate 7 , and the silicone scraper can be in contact with the conveying crawler 5 .
[0036] In this embodiment, the adjustment plate 7 serves as the installation base for the silicone scraper. The silicone material has good elasticity and wear resistance, and can effectively scrape off impurities such as slag and soil attached to the surface of the conveyor belt 5 when in contact with the conveyor belt 5. The design of the silicone scraper takes into account the fit with the belt and the scraping effect, ensuring the efficient cleaning work. The clean conveyor belt 5 can better cooperate with components such as the support roller 4 and the adjustment shaft 13 to reduce the sliding or offset problems caused by impurities, thereby enhancing the overall stability and reliability of the equipment.
[0037] In a further preferred embodiment of the present invention, the mounting frame 3 is U-shaped, the adjusting shaft 13 is located in the mounting frame 3, a heat dissipation port is provided on one side of the two motors 6, and dustproof nets are installed in the two heat dissipation ports.
[0038] In this embodiment, the U-shaped structure enables effective utilization of the internal space of the mounting frame 3, facilitating the installation and maintenance of components such as the adjusting shaft 13. The design of the heat dissipation port enables the motor 6 to effectively discharge heat during operation, maintaining the normal operating temperature of the motor 6, thereby extending the service life of the motor 6 and improving the working efficiency. The main function of the dustproof net is to prevent external pollutants such as dust and impurities from entering the interior of the motor 6 through the heat dissipation port and causing damage to the motor 6.
[0039] To sum up, compared with the relevant technology, this device can adjust the tension of the conveyor belt 5 by setting the adjustment shaft 13 to contact the conveyor belt 5, and can adjust the height of the adjustment shaft 13 by adjusting the extension length of the output rod of the cylinder 17. The tension of the conveyor belt 5 can be monitored by the pressure sensor, and the automatic adjustment of the tension can be achieved by cooperating with the cylinder 17 without too much manual participation. By setting the dust reduction component, the slag dust can be processed, environmental pollution can be reduced, and the health of personnel can be protected.
