[0002] In the production operation of open-pit mines, belt conveyors are important transportation equipment. However, in some areas, the outdoor temperature is generally low in winter. The moisture in materials such as coal and factors such as external snowmelt will cause the materials to freeze and adhere to the outer side of the belt to form frozen objects. As the thickness of the frozen objects on the outer side of the belt continues to increase, the normal operation of the belt conveyor is affected. Since the frozen objects have a high hardness, they have a strong adhesion to the outer side of the belt. In addition, during the operation of the belt conveyor, especially at positions where the belt conveyor has a large inclination angle, the belt will jump, pile up, scatter, and deviate. At the same time, it will aggravate the wear of the rollers, and the load of the roller shaft will also increase. The current cleaning device mainly breaks the frozen objects by beating and vibrating, and the cleaning effect is poor. It is not only easy to shake off the materials carried on the belt, but also easy to cause damage to the belt conveyor. Summary of the invention

[0033] The present invention provides a freezing material cleaning device 100 for a belt conveyor 200.

[0034] Please refer to Figure 1 - Figure 2 , the belt conveyor 200 has two rollers 202 and a belt 201 sleeved outside the two rollers 202 and used for conveying materials. The belt 201 has a load-carrying section 2011 and a return section 2012 located on the upper and lower sides of the roller 202, and one end of the return section 2012 that is turned upwards is a scraping end 2013.

[0035] In an embodiment of the present invention, the freezing material cleaning device 100 includes a support frame 1, a crushing mechanism 2, an adjusting mechanism 3, and a scraping mechanism 4; each roller 202 is rotatably installed on the support frame 1; the crushing mechanism 2 includes a crushing roller 22 and a pressing roller 21 located above the crushing roller 22. The crushing roller 22 and the pressing roller 21 are both rotatably installed on the support frame 1, and the pressing roller 21 and the crushing roller 22 are respectively arranged on the inner and outer sides of the return section 2012 to cooperate in crushing the frozen materials adhered to the outer side of the return section 2012; the adjusting mechanism 3 is installed on the support frame 1, and the adjusting mechanism 3 is connected to the pressing roller 21 and used to drive the pressing roller 21 to move up and down; the scraping mechanism 4 is installed on the support frame 1 and is arranged close to the scraping end 2013, and the scraping mechanism 4 is used to scrape the outer side of the return section 2012.

[0036] The freezing material cleaning device 100 of the present invention is provided with a crushing mechanism 2 on the support frame 1. The crushing mechanism 2 includes a crushing roller 22 and a squeezing roller 21, and the crushing roller 22 and the squeezing roller 21 are respectively located inside and outside the return section 2012. When the return section 2012 passes between the crushing roller 22 and the squeezing roller 21, the squeezing roller 21 can prevent the return section 2012 from moving upward. Through the cooperation of the crushing roller 22 and the squeezing roller 21, the freezing material attached to the outside of the return section 2012 can be squeezed and crushed; in addition, a scraping mechanism 4 is also provided near the scraping end 2013. The scraping mechanism 4 is installed on the support frame 1 to maintain stable structure. Since some of the crushed freezing material may still remain on the outside of the return section 2012, the scraping mechanism 4 helps to scrape the remaining freezing material clean to ensure that there is no freezing material on the loading section 2011, so as to facilitate the loading and transportation of materials and ensure the normal operation of the belt conveyor 200. Compared with the prior art method of crushing freezing materials by patting and vibrating, the freezing material cleaning device 100 of the present invention uses the method of extrusion to crush freezing materials, which can not only effectively crush freezing materials, reduce the impact on the belt conveyor 200 caused by vibration and patting, and is not easy to damage the belt conveyor 200. In addition, a scraping mechanism 4 is also provided to scrape the remaining crushed freezing materials, and the cleaning effect is better.

[0037] It should be noted that, according to the working mode, the loading section 2011 is a part for loading and transporting materials, while the return section 2012 is located below the loading section 2011 and is not used for loading goods. The forward direction of the return section 2012 is opposite to that of the loading section 2011, and the return section 2012 and the loading section 2011 are connected end to end to form a closed loop.

[0038] It can be understood that when the return section 2012 moves forward, due to the relatively thick thickness of the freezing material on its outside, it is in mutual contact with the crushing roller 22 and the squeezing roller 21. Since both the crushing roller 22 and the squeezing roller 21 can rotate, when the crushing roller 22 rotates, the freezing material on the outside of the return section 2012 is crushed.

[0039] Among them, the scraping mechanism 4 is relatively stationary, and during the movement of the belt 201, it passes through the scraping mechanism 4 to scrape off the freezing material on the outside of the return section 2012.

[0040] Specifically, in this embodiment, both the crushing roller 22 and the squeezing roller 21 are arranged along the width direction of the belt 201. The scraping end 2013 is located outside the roller 202, and the scraping end 2013 is located at the end position of the return section 2012 along its forward direction.

[0041] Further, the support frame 1 includes two support rods 12, the two support rods 12 are respectively located at opposite ends of each roller 202, and the roller shafts 203 of each roller 202 are respectively rotatably connected to the two support rods 12; to ensure that the support rod 12 remains relatively stable relative to the roller 202, with good reliability.

[0042] Both ends of the crushing roller 22 and the pressing roller 21 are respectively rotatably connected to the two support rods 12.

[0043] In an embodiment, a plurality of protrusions 221 are circumferentially spaced along the outer periphery of the crushing roller 22, and the plurality of protrusions 221 are all spirally wound around the outer periphery of the crushing roller 22, and a guiding groove is formed between any two adjacent protrusions 221.

[0044] It can be understood that the spirally arranged protrusions 221 can exert a stronger and more uniform shearing force and pressing action on the frozen material when the crushing roller 22 rotates, which helps to more effectively crush the material frozen on the tape 201. Moreover, the existence of the guiding groove can help guide the crushed frozen material to move along the extending direction of the guiding groove, avoid the material from accumulating in the guiding groove during the crushing process, and contribute to maintaining the continuous operation ability of the crushing roller 22.

[0045] In an embodiment, two mounting ears 11 are provided on the support frame 1, two vertical sliding holes 111 are respectively formed in the two mounting ears 11, and both ends of the pressing roller 21 are respectively rotatably mounted on the two mounting ears 11 through two first rotating shafts 211; both ends of the crushing roller 22 are respectively rotatably inserted into the two sliding holes 111 through two second rotating shafts 222, and can slide vertically along the sliding holes 111; the number of the adjusting mechanisms 3 is two, the two adjusting mechanisms 3 are respectively mounted on the two mounting ears 11, and each adjusting mechanism 3 can drive the corresponding second rotating shaft 222 to move up and down to drive the pressing roller 21 to move up and down.

[0046] It can be understood that by providing two mounting ears 11 on the support frame 1 and forming vertical sliding holes 111 in each mounting ear 11, the crushing roller 22 can slide vertically along the sliding holes 111 according to actual needs, and then adjust the distance from the pressing roller 21, so as to flexibly adjust the pressing pressure between the two, so as to achieve the best crushing effect, with better flexibility and can be adaptively adjusted according to the freezing situation.

[0047] Specifically, the two mounting ears 11 are respectively arranged at the bottoms of the two support rods 12, and the two mounting ears 11 are integrally formed with the two support rods 12 respectively.

[0048] In one embodiment, slide rails 113 extending vertically are provided on two opposite hole walls of the sliding hole 111; a slider 223 is rotatably connected to the outside of the second rotating shaft 222, and first sliding grooves (not shown in the figure) that are slidably engaged with the two slide rails 113 are respectively formed on opposite sides of the slider 223.

[0049] It can be understood that the cooperation between the slide rails 113 and the first sliding grooves enables the second rotating shaft 222 to move up and down in the sliding hole 111 more smoothly, avoiding problems such as shaking or deviation that may be caused by simply relying on the inner wall of the sliding hole 111 for guiding. This helps to ensure the uniform distribution of the pressure between the crushing roller 22 and the extrusion roller 21, improving the crushing effect; at the same time, it also makes it more convenient and fast for the crushing roller 22 to move vertically.

[0050] As Figure 1 shown, the left slider 223 cooperates with the left sliding hole 111, and the right slider 223 cooperates with the right sliding hole 111, so as to respectively realize the vertical adjustment of the two second rotating shafts 222, with higher precision.

[0051] Specifically, slide rails 113 extending vertically are formed on the front and rear hole walls of each sliding hole 111. Among them, the front and rear hole walls of each sliding hole 111 have a certain thickness in the left-right direction, which is also the width direction of the tape, so as to enhance the structural strength of each mounting ear 11 and realize more stable limiting of the crushing roller 22 in the front-rear direction, so that when the return section 2012 travels in the front-rear direction, the crushing roller 22 remains relatively stable, thereby better crushing the frozen material.

[0052] In one embodiment, an opening 112 communicating with the sliding hole 111 is formed at the bottom of each mounting ear 11. Each adjusting mechanism 3 includes an adjusting rod 32, an end plate 31 and an elastic component 33. The end plate 31 is detachably connected to the corresponding mounting ear 11 and closes the opening 112. The adjusting rod 32 is movably connected to the end plate 31 at a position corresponding to the opening 112, and the adjusting rod 32 can move vertically relative to the end plate 31. The top of the adjusting rod 32 extends into the sliding hole 111 from the opening 112 and is connected to the bottom end of the elastic component 33. The top end of the elastic component 33 is connected to the bottom of the slider 223.

[0053] It can be understood that an opening 112 is provided at the bottom of the connecting ear, so that when the slider 223 is installed, the slider 223 can enter the sliding hole 111 from the opening 112 and slide with the hole wall of the sliding hole 111, and an end plate 31 is provided at the opening 112 to prevent the slider 223 from sliding off the opening 112, thereby improving reliability; and an elastic component 33 is provided between the end plate 31 and the slider 223, so that the slider 223 has a certain vertical movement space, when some larger frozen objects move to abut against the crushing roller 22, the crushing roller 22 can compress the elastic component 33 to move downward, thereby avoiding the tape 201 being limited and stuck; and the elastic component 33 can exert an elastic force on the crushing roller 22, so that the crushing roller 22 can give a certain extrusion force to the frozen object, thereby crushing the frozen object, and has strong adaptability.

[0054] In addition, by setting the adjustment rod 32, the elastic force applied by the elastic component 33 to the crushing roller 22 can be adjusted, and the pressure applied by the crushing roller 22 to the return section 2012 is further adjusted, while ensuring that the tape 201 is not damaged and the frozen objects can be effectively crushed.

[0055] It can be understood that the two adjustment mechanisms 3 are arranged in a one-to-one correspondence with the two mounting ears 11 , and the two adjustment mechanisms 3 are used to adjust the two second rotating shafts 222 respectively.

[0056] In one embodiment, the adjusting rod 32 is an adjusting screw. A threaded hole is provided at a position of the end plate 31 corresponding to the opening 112 . The adjusting rod 32 is threadedly matched with the threaded hole, and the screw head of the adjusting screw is located at the bottom of the end plate 31 .

[0057] It is understood that very fine height adjustment can be achieved by means of an adjusting screw. Since the spacing between the threads is very small, the position of the crushing roller 22 can be changed in small increments when the adjusting screw is turned, thereby providing accurate control of the extrusion pressure to accommodate frozen objects of different thicknesses and hardnesses.

[0058] The two adjusting screws are used to drive the two elastic components 33 to move vertically, so as to adjust the elastic force applied by the two elastic components 33 to the two second rotating shafts 222 of the crushing roller 22; the screw head is located at the bottom of the end plate 31 to facilitate the turning of the adjusting screw.

[0059] In one embodiment, each elastic component 33 includes a slide plate 331 and a plurality of springs 332, the plurality of springs 332 are arranged on the top of the slide plate 331, and second slide grooves slidably matched with the two slide rails 113 are respectively opened on opposite sides of the slide plate 331, the top of the adjusting rod 32 is connected to the slide plate 331, and the top of the plurality of springs 332 is connected to the slider 223.

[0060] Understandably, a plurality of springs 332 are arranged on the top of the slide plate 331, and the tops of these springs 332 are connected to the slider 223. Such a design can keep the springs 332 stable during the crushing process and can apply a greater elastic force to the crushing roller 22, thereby effectively crushing the frozen matter.

[0061] In one embodiment, the scraping mechanism 4 includes a mounting frame 41 and a scraper 42 for scraping the outer side of the return section 2012. The bottom of the mounting frame 41 is detachably mounted on the support frame 1, and the scraper 42 is detachably mounted on the top of the mounting frame 41.

[0062] Understandably, since the bottom of the mounting frame 41 also adopts a detachable mounting method, the position of the scraping mechanism 4 can be flexibly adjusted according to actual needs to ensure good contact between the scraper 42 and the surface of the tape 201. The scraper 42 is detachably mounted on the top of the mounting frame 41, which is convenient for replacing the scraper 42 separately after it is damaged, saving costs.

[0063] In one embodiment, a connecting groove is provided on one side of the mounting frame 41 facing the tape 201; one end of the scraper 42 away from the tape 201 is the connecting end 421, and the end close to the tape 201 is the working end 422. The connecting end 421 extends into the connecting groove and is fastened to the connecting groove by a fastener. The working end 422 is used for scraping the outer side of the return section 2012, and the scraper 42 is arranged to be inclined downward from the connecting end to the working end 422.

[0064] Understandably, the downward inclination of the scraper 42 makes the contact angle with the surface of the tape 201 an obtuse angle, which is convenient for the scraper 42 to more effectively remove the frozen matter during the movement of the tape 201.

[0065] In addition, the connecting end 421 extends into the connecting groove and is fastened to the connecting groove by a fastener, making the scraper 42 more stable and reliable.

[0066] Furthermore, two fixing seats 13 are respectively arranged on the two support rods 12, and the two ends of the mounting frame 41 are respectively fixedly connected to the two fixing seats 13, enhancing the structural stability of the mounting frame 41.

[0067] Specifically, a card slot is provided at the top of each fixing seat 13, and card joints 411 that are engaged with the card slots are respectively arranged at the two ends of the mounting frame 41. The card joints 411 extend into the card slots and are fastened to the card slots by bolts. Understandably, through the cooperation of the card joints and the card slots, the mounting frame 41 is further limited to prevent the mounting frame 41 from shaking or moving.
