[0032] An intelligent control device for a coal mine belt conveyor, such as Figure 1As shown in the figure, it includes a conveyor belt 1. A guiding bracket 100 is arranged on the lower side of the conveyor belt 1. The number of guiding brackets 100 can be adjusted according to the length of the conveyor belt conveyor. It also includes a U-shaped frame A201. A deviation rectifying mechanism for adjusting the position of the conveyor belt 1 is arranged on the guiding bracket 100. Through the deviation rectifying mechanism, the conveyor belt 1 can be effectively prevented from running off track. Two U-shaped frames A201 are respectively arranged at the head and the tail of the conveyor. Rotating rollers A202 are rotatably connected to both of the two U-shaped frames A201. An adjusting mechanism for adjusting the tension of the conveyor belt 1 is arranged on the side of the rotating roller A202. Through the adjusting mechanism, the conveyor belt 1 can be effectively prevented from continuously slipping. The adjusting mechanism includes a sleeve 301. The surface of the sleeve 301 is in contact with one side of the conveyor belt 1 close to the rotating roller A202. A U-shaped frame B203 is arranged on one side of each U-shaped frame A201. Rotating rollers B204 are rotatably connected to both of the U-shaped frames B203. Both the rotating roller A202 and the rotating roller B204 are in driving connection with the conveyor belt 1. A driving motor 205 is installed on the side of the right U-shaped frame A201. The output shaft of the driving motor 205 is fixedly connected to the rotating roller A202.

[0033] As Figure 2 shown, the adjusting mechanism further includes a connecting frame 302. The connecting frame 302 is fixedly connected to the right U-shaped frame B203. An electric push rod A303 is installed on the connecting frame 302. The movable end of the electric push rod A303 is fixedly connected to a U-shaped frame C304.

The transmission component is composed of a first sprocket, a second sprocket and a chain. Among them, the first sprocket is fixedly connected to the right rotating roller A202, the second sprocket is fixedly connected to the rotating shaft 305, and a chain is connected between the first sprocket and the second sprocket. The sleeve 301 is sleeved on the rotating shaft 305. A first elastic member is arranged between the sleeve 301 and the rotating shaft 305. The first elastic member is a torsion spring.

[0034] As Figure 3 shown, the adjusting mechanism further includes a pressing block 306. The pressing block 306 is fixedly connected to the middle part of the inner wall of the sleeve 301. A trigger switch 307 is fixedly installed on the rotating shaft 305. The trigger switch 307 is electrically connected to the electric push rod A303. When the pressing block 306 moves, it contacts the trigger switch 307.

[0035] As Figure 2As shown in the figure, the adjusting mechanism further includes an intelligent control cabinet 308. The intelligent control cabinet 308 is installed in the middle of the front side of the C-shaped frame A201. The trigger switch 307 is electrically connected to the intelligent control cabinet 308. An electric push rod B309 is installed at the lower part of the C-shaped frame A201. The electric push rod B309 is electrically connected to the intelligent control cabinet 308. The movable end of the electric push rod B309 is fixedly connected to a C-shaped frame D310. A regulating shaft 311 is rotatably connected to the C-shaped frame D310. The regulating shaft 311 contacts the conveyor belt 1. By driving the regulating shaft 311 to move up and down through the electric push rod B309, the tension of the conveyor belt 1 can be adjusted.

[0036] As Figure 4-5 shown in the figure, the deviation rectifying mechanism includes a support frame 401. The support frames 401 are fixedly connected to the upper parts of the guiding brackets 100. L-shaped frames 402 are symmetrically and fixedly connected to the tops of the support frames 401. Rotating sleeves 403 are rotatably connected to the ends of the L-shaped frames 402. When the conveyor belt 1 deviates, the conveyor belt 1 can contact the rotating sleeves 403. Turntables 4031 are rotatably connected to the inner tops of the rotating sleeves 403. Lifting plates 404 are slidably connected to the interiors of the rotating sleeves 403. A second elastic member is arranged between the turntables 4031 and the lifting plates 404. The second elastic member is a tension spring. Spiral tracks 405 are formed in the interiors of the rotating sleeves 403. Convex shafts are symmetrically and fixedly connected to the side walls of the lifting plates 404. The convex shafts of the lifting plates 404 are respectively caught in the corresponding spiral tracks 405 and slide in the spiral tracks 405.

[0037] As Figure 4-6 shown in the figure, the deviation rectifying mechanism further includes a spline shaft 501. The spline shaft 501 is fixedly connected to the bottom of the lifting plate 404. Spline sleeves 502 are rotatably connected to the left sides of the bottoms of the L-shaped frames 402. The bottoms of the spline shafts 501 are respectively caught in the corresponding spline sleeves 502 and slide in the spline sleeves 502. Gears 503 are fixedly connected to the bottoms of the spline sleeves 502. Rack bars 504 are meshed with the sides of the gears 503. The rack bars 504 are slidably connected to the L-shaped frames 402. Elastic pawls 505 are hinged to the rack bars 504. Limit grooves are formed in the L-shaped frames 402. The elastic pawls 505 are caught in the limit grooves of the L-shaped frames 402.

[0038] As Figure 7-8 shown in the figure, the deviation rectifying mechanism further includes an adjusting rod 601. The adjusting rods 601 are slidably connected to one sides of the bottoms of the L-shaped frames 402. The adjusting rods 601 are fixedly connected to the rack bars 504. Discs 602 are rotatably connected to the support frames 401. Teeth are arranged at positions of the adjusting rods 601 close to the discs 602. Tooth grooves are formed in the side walls of the discs 602. The teeth of the adjusting rods 601 are caught in the tooth grooves of the discs 602. Side frames 603 are fixedly connected to the tops of the discs 602 through connecting shafts. Roller supports C604 are rotatably connected to the side frames 603. The roller supports C604 contact the conveyor belt 1.

[0039] As Figure 7-8As shown, a cleaning mechanism is also included, which includes an elastic slider A701, the elastic slider A701 is slidably connected in the side frame 603, a tooth plate A702 is hinged between the two elastic sliders A701, a third elastic member is arranged between the tooth plate A702 and the two elastic sliders A701, the third elastic member is a torsion spring, the tooth plates A702 are in contact with the lower surface of the roller C604, and the sides of the elastic sliders A701 are rotatably connected with damping wheels A703, no damping is generated when the damping wheel A703 rotates clockwise, and damping is generated when the damping wheel A703 rotates counterclockwise, and the damping generated by the damping wheel A703 can slow down the speed at which the elastic slider A701 slides upward, and the damping wheel A703 is in contact with the side frame 603.

[0040] like Figure 9-10 As shown, the cleaning mechanism also includes a connecting plate 801, and the connecting plates 801 are symmetrically fixed on the support frame 401. The upper parts of the two connecting plates 801 are commonly rotatably connected with a roller D802. The upper parts of the adjacent side walls of the two connecting plates 801 are slidably connected with elastic sliders B803. A tooth plate B804 is hinged between the two elastic sliders B803, and the tooth plate B804 is in contact with the lower surface of the roller D802. The side of the elastic slider B803 is rotatably connected with a damping wheel B805, and the damping wheel B805 is in contact with the connecting plate 801. No damping is generated when the damping wheel B805 rotates clockwise, and damping is generated when the damping wheel B805 rotates counterclockwise. The damping generated by the damping wheel B805 can slow down the speed at which the elastic slider B803 slides upward.

[0041] Initially, the conveyor belt 1 is in a flat state without being affected by external forces. When coal needs to be transported, the coal is placed on the conveyor belt 1 through equipment in the prior art. The middle part of the conveyor belt 1 collapses downward due to the weight of the coal until it contacts the roller C604 and the roller D802. Then the drive motor 205 is started, and the output shaft of the drive motor 205 drives the conveyor belt 1 to start moving through the roller A202 on the right. Driven by the roller A202, the conveyor belt 1 starts to move around the two rollers A202 and the two rollers B204 to transport the coal.

[0042] When the conveyor belt 1 is put into production for the first time or after being used for a long time, it is necessary to adjust the tension of the conveyor belt 1 to prevent the conveyor belt 1 from slipping during movement. If the conveyor belt 1 slips for a long time, the conveyor belt 1 is easily broken due to the friction of the rollers, which leads to the interruption of coal mine transportation. It is necessary to invest a lot of time, manpower and funds to repair and maintain the conveyor line. The adjustment mechanism in this device can effectively avoid the above situation. Specifically, the first sprocket in the transmission assembly is driven to rotate by the roller A202 on the right side, and the first sprocket drives the second sprocket to rotate through the chain. The second sprocket drives the rotating shaft 305 to rotate synchronously with the roller A202 on the right side. At the same time, the friction between the conveyor belt 1 and the outer surface of the casing 301 makes the casing 301 rotate with the conveyor. The conveyor belt 1 rotates synchronously with the movement speed. When the conveyor belt 1 does not slip, the rotation speeds of the sleeve 301 and the shaft 305 are kept consistent, and the sleeve 301 drives the extrusion block 306 to keep a distance from the trigger switch 307. When the conveyor belt 1 slips, the sleeve 301 rotates due to the slip of the conveyor belt 1 and will stop briefly with the conveyor belt 1, while the shaft 305 will continue to rotate, thereby shortening the distance between the trigger switch 307 and the extrusion block 306, and contracting the first elastic member between the sleeve 301 and the shaft 305. When the conveyor belt 1 continues to slip, the distance between the trigger switch 307 and the extrusion block 306 will shorten again, and the first elastic member between the sleeve 301 and the shaft 305 will continue to contract. As the conveyor belt 1 continues to slip, the trigger switch 307 and the extrusion block 306 gradually approach each other, and the extrusion block 306 contacts and squeezes the trigger switch 307. After the trigger switch 307 is squeezed, the electric push rod A303 is activated, and the movable end of the electric push rod A303 drives the rotating shaft 305 to drop a short distance downward through the yoke C304. After the rotating shaft 305 moves, it drives the sleeve 301 to move until it is no longer in contact with the surface of the conveyor belt 1. At this time, the sleeve 301 is released through the first elastic member to drive the extrusion block 306 to rotate and reset, so that the extrusion block 306 is reset to the initial position, and the electric push rod A303 transmits a signal to the intelligent control cabinet 308, and the intelligent control cabinet 308 controls the movable end of the electric push rod B309 to drive the adjusting shaft 311 through the yoke D310. Move downward, and after the adjusting shaft 311 moves downward, the tension of the conveyor belt 1 is adjusted by squeezing the surface of the conveyor belt 1, so that the friction between the conveyor belt 1 and the roller A202 is increased, thereby solving the slippage of the conveyor belt 1, and then the movable end of the electric push rod A303 moves to drive the sleeve 301 to reset. After the sleeve 301 is reset, it contacts the surface of the conveyor belt 1 again and rotates synchronously with the speed of the conveyor belt 1. The contact between the sleeve 301 and the conveyor belt 1 can monitor the slippage of the conveyor belt 1 in real time, and the sleeve 301 is stopped briefly when the conveyor belt 1 slips, so that the rotation angle of the sleeve 301 and the rotating shaft 305 can be misaligned, so as to more accurately judge whether the conveyor belt 1 slips and adjust the tension of the conveyor belt 1 in time.

[0043] When conveyor belt 1 is transporting coal, the uneven distribution of the center of gravity of the coal carried by conveyor belt 1 will cause different degrees of contact between conveyor belt 1 and roller C604, thereby causing conveyor belt 1 to deviate. If it is not adjusted in time, conveyor belt 1 will be worn and its service life will be shortened. In severe cases, conveyor belt 1 will detach from roller C604 and roller D802, and then the coal mine belt conveyor will need to be shut down for maintenance, which is time-consuming and labor-intensive, and causes huge losses to the project.

[0044] When the conveyor belt 1 is not offset, the transverse center line of the conveyor belt 1 coincides with the transverse center line of the roller D802, and there is a gap between the two side edges of the conveyor belt 1 and the two adjacent rotating sleeves 403. When the conveyor belt 1 is offset, the conveyor belt 1 will contact the rotating sleeve 403 on the front or rear side. At this time, the rotating sleeve 403 is affected by the friction of the conveyor belt 1 and rotates around the connection point of the L-shaped frame 402 as the center. Since the position where the coal mine falls on the conveyor belt 1 cannot be accurately controlled, the conveyor belt 1 may only be briefly offset and then automatically return to the center line of the roller D802. Taking the rotating sleeve 403 on the front side as an example, when the conveyor belt 1 briefly deviates to the front side, the conveyor belt 1 briefly contacts the rotating sleeve 403, and the rotating sleeve 403 is forced to rotate counterclockwise and squeeze the convex shaft of the lifting plate 404 through the spiral track 405 to make the lifting plate 404 rotate. The lowering plate 404 moves vertically downward, and the second elastic member between the lifting plate 404 and the rotating plate 4031 is forced to extend along the lifting plate 404. The lifting plate 404 drives the spline shaft 501 to slide downward in the limiting hole of the spline sleeve 502. At this time, the lifting plate 404 cannot drive the spline sleeve 502 to rotate. When the conveyor belt 1 is reset, it no longer contacts the rotating sleeve 403. The rotating sleeve 403 no longer rotates after being released from the restriction. At this time, the second elastic member between the lifting plate 404 and the rotating plate 4031 contracts and drives the lifting plate 404 to move and reset. After the lifting plate 404 moves, the convex shaft thereon squeezes the spiral track 405 to make the rotating sleeve 403 rotate clockwise. After the rotating sleeve 403 rotates, the lifting plate 404 can rise and reset along the spiral track 405, thereby preventing the conveyor belt 1 from being triggered when it is temporarily offset. The deviation correction mechanism is thus prevented.

[0045] When the conveyor belt 1 continues to deviate, the conveyor belt 1 continues to contact the rotating sleeve 403 to make the rotating sleeve 403 continue to rotate. The rotating sleeve 403 squeezes the convex shaft of the lifting plate 404 through the spiral track 405 to make the lifting plate 404 move downward to the bottom of the spiral track 405. At this time, the lifting plate 404 cannot continue to descend. The spiral track 405 squeezes the convex shaft of the lifting plate 404 to drive the lifting plate 404 to rotate synchronously with the rotating sleeve 403. The lifting plate 404 drives the spline sleeve 502 to rotate counterclockwise through the spline shaft 501. The sleeve 502 drives the gear 503 to rotate counterclockwise, so that the gear 503 drives the elastic pawl 505 and the adjusting rod 601 to move to the left through the rack 504. When the elastic pawl 505 moves, it is squeezed by the limit groove of the L-shaped frame 402 and continuously rotates with the connection point of the rack 504 as the center. When the adjusting rod 601 moves, the teeth on it squeeze the tooth groove of the shaft disc 602, so that the shaft disc 602 drives the side frame 603 to rotate clockwise, and the side frame 603 drives the roller C604 to rotate. After the roller C604 rotates, the conveyor belt 1 is driven by the roller C604. 4. The angle of the conveyor belt 1 can gradually move to coincide with the center line of the roller D802 again and reset. After the conveyor belt 1 is reset, it no longer contacts the rotating sleeve 403. After the rotating sleeve 403 is freed from the restriction, it no longer rotates. At this time, the second elastic member between the lifting plate 404 and the rotating plate 4031 contracts to drive the lifting plate 404 to move and reset. When the lifting plate 404 moves upward, it will not drive the spline sleeve 502 to rotate, so that the angle of the roller C604 remains stable, and the roller C604 can be made stable by the elastic ratchet 505 being stuck in the limit groove of the L-shaped frame 402. The angle of C604 is further kept stable. After the lifting plate 404 moves, the convex shaft thereon squeezes the spiral track 405 to make the rotating sleeve 403 rotate clockwise. After the rotating sleeve 403 rotates, the lifting plate 404 can rise and reset along the spiral track 405, thereby completing the deviation correction of the conveyor belt 1 by the correction mechanism. When the conveyor belt 1 deviates, the movement state of the conveyor belt 1 can be monitored in real time through the timely contact between the rotating sleeve 403 and the conveyor belt 1, thereby preventing the conveyor belt 1 from seriously deviating during the movement process.

[0046] Due to the working environment, during the movement of conveyor belt 1, smaller coal particles will fall on the side of conveyor belt 1 that contacts roller A202, roller B204, roller C604 and roller D802. If the coal particles are not cleaned in time, they will move with conveyor belt 1. When the coal particles move to rollers A202, roller B204, roller C604 and roller D802, the coal particles will be squeezed and stuck into the surface of conveyor belt 1 or rollers A202, roller B204, roller C604 and roller D802. In this case, the continued use of conveyor belt 1, rollers A202, rollers B204, rollers C604 and roller D802 will cause conveyor belt 1 to deviate, conveyor belt 1 to rupture and rollers A202 to break. 02. Roller B204, roller C604 and roller D802 are damaged. When conveyor belt 1 moves, conveyor belt 1 contacts and rubs with the surfaces of roller C604 and roller D802 respectively, causing roller C604 and roller D802 to rotate around the connection between side frame 603 and connecting plate 801. The top surface of tooth plate A702 fits with the bottom surface of roller C604. When coal particles are stuck in the surface of roller C604, roller C604 drives the coal particles to rotate to tooth plate A702. After tooth plate A702 contacts the coal particles, it rotates clockwise around the connection between elastic slider A701 and the third elastic member between tooth plate A702 and elastic slider A701 is contracted by force. , after the tooth plate A702 rotates, the corner fits with the surface of the roller C604. At this time, the corner of the tooth plate A702 is squeezed by the surface of the roller C604, so that the elastic slider A701 drives the damping wheel A703 to quickly shrink and slide downward in the side frame 603. When the damping wheel A703 slides downward, the damping wheel A703 itself will not generate damping, so that the elastic slider A701 can slide smoothly. After the roller C604 continues to rotate, the coal particles on its surface fit with the bottom surface of the corner of the tooth plate A702. At this time, the roller C604 continues to rotate, and the tooth plate A702 can scrape off the coal particles on the surface of the roller C604. After the coal particles are scraped off, the surface of the roller C604 becomes flat again, and the coal particles fall off It falls to the bucket-shaped area at the bottom of the side frame 603. At this time, the tooth plate A702 is released to rotate and reset through the third elastic member. At the same time, the elastic slider A701 drives the damping wheel A703 and the tooth plate A702 to release and slide to reset. If the elastic slider A701 resets too fast, the top corner of the tooth plate A702 is not rotated and reset in time, which may collide with the surface of the roller C604 and cause damage to the equipment. When the damping wheel A703 fits the side frame 603 and moves to reset, the damping wheel A703 can drive the elastic slider A701 to slowly release and reset through the damping generated by itself, so that the tooth plate A702 completes the rotation and reset before it rises to the initial position, so that the tooth plate A702 avoids collision with the roller C604 after rising and resetting.

[0047] When coal particles are stuck on the surface of the roller D802, the elastic slider B803, the tooth plate B804 and the damping wheel B805 repeat the same steps as above to clean the surface of the roller D802.

[0048] Example 2

[0049] like Fig.11 As shown, the cleaning mechanism also includes a support rod 901, the support rod 901 is arranged at the lower part of the conveyor belt 1, a collecting bucket 902 is fixedly connected to the support rod 901, the collecting bucket 902 is in contact with the conveyor belt 1, a cleaning frame 903 is fixedly connected to the collecting bucket 902, the cleaning frame 903 is in contact with the conveyor belt 1, the contact portion between the cleaning frame 903 and the conveyor belt 1 is V-shaped, the side of the cleaning frame 903 is rotatably connected with a tooth plate C904, and the tooth plate C904 is in contact with the conveyor belt 1.

[0050] When the inner surface of the conveyor belt 1 in contact with the roller is stuck with coal particles, the conveyor belt 1 drives the coal particles to the tooth plate C904 as the conveyor belt 1 moves. The coal particles contact the tooth plate C904. At this time, the toothed surface at the bottom of the tooth plate C904 is forced to rotate counterclockwise with the connection point of the elastic slider B803 as the center. The fourth elastic member between the tooth plate C904 and the sliding rod is forced to shrink. After the tooth plate C904 rotates, the corner fits the surface of the conveyor belt 1. Due to the material of the conveyor belt 1, the tooth plate After C904 rotates, it will not have a hard collision with the conveyor belt 1. After the conveyor belt 1 continues to move, the corner of the tooth plate C904 will scrape off the coal particles on the surface of the conveyor belt 1. The scraped coal particles continue to move with the conveyor belt 1 to the V-shaped surface of the cleaning frame 903. The continued movement of the conveyor belt 1 can make the coal particles move along the V-shaped surface of the cleaning frame 903 and fall into the collecting bucket 902, thereby completing the cleaning of the contact surface between the conveyor belt 1 and the roller, which can effectively extend the service life of the conveyor belt 1.
