Abstract
Description
Technical Field
[0001] This invention belongs to the field of material transportation technology, specifically a scraper conveyor for coal mining. Background Technology
[0002] Scraper conveyors are transportation machines used in coal mining faces. They are mainly used for transportation in coal mining faces and mining area roadways, and can also be used in coal roadways and semi-coal-rock roadway excavation faces.
[0003] Existing scraper conveyors mainly consist of a motor and a conveyor belt. During operation, the motor moves the coal mine via the conveyor belt. The motor's power consumption is directly proportional to the mass of the conveyor belt itself and the mass of the coal mine it carries. The higher the ratio of the coal mine's mass to the conveyor belt's mass, the higher the motor's effective power consumption. For long-distance transportation and indirect feeding processes, when the mass of the coal mine is less than the mass of the conveyor belt, the motor's effective power consumption will be lower than its ineffective power consumption. As the length of the conveyor belt increases, its ineffective power consumption will also increase, resulting in a large amount of ineffective energy consumption during transportation.

[0011] The beneficial effects of this invention are as follows:
[0012] 1. This invention uses a first support mechanism to drive the thin belt to rotate, thereby minimizing the mass of the thin belt, increasing the ratio between the coal mass and the thin belt mass, improving energy efficiency, and facilitating installation. Then, through a forward-starting drive mechanism, the sleeve block sequentially passes through the elastic element, the second push plate, and the load plate in the left-side housing cavity, pressing the load plate above the carrier rod tightly against the back of the water tank. Next, the coal is inverted onto the upper surface of the load plate at the top of the carrier rod. As the amount of coal on the upper surface of the load plate increases, the downward pressure on the carrier rod on the second support mechanism increases. Move the load until the bottom of the load plate is completely separated from the top of the support rod. At this point, the pressure on the support rod during movement can be controlled by increasing or decreasing the number of weights. This adjusts the amount of coal transported on the upper surface of a single load plate each time, ensuring that the coal above the load plate does not slip. When the coal density is high, increasing the number of weights increases the coal transport volume, while when the coal density is low, decreasing the number of weights prevents the coal from piling up too high above the load plate and slipping. At the same time, reducing the number of load plates used increases the ratio between the coal mass and the belt mass.
[0013] 2. In this invention, after the bottom surface of the carrying plate is completely separated from the top of the carrying rod, the compressed elastic element recovers. The second pusher pushes the carrying plate inside the housing that is in contact with it to the top of the carrying rod. Then, the drive mechanism is activated in reverse. The drive mechanism drives the first pusher to squeeze the carrying plate above the first support block and move it into the housing through the first slot. When the thin belt and the conical teeth move the carrying plate to the upper surface of the inclined block, the conical teeth moving to the right drive the carrying plate to push the stopper to the right. The inclined block on the unloading mechanism pushes the carrying plate upward until the carrying plate separates from the conical teeth. The carrying plate on the upper surface of the inclined block tilts backward under the action of the inclined surface of the inclined block. The tilted carrying plate carries the coal and slides into the unloading box and flips over, so that the coal is separated from the upper surface of the carrying plate. Then, the carrying plate slides from the opening at the bottom of the unloading box to the inner side of the bottom of the thin belt and is finally transported by the thin belt to the upper surface of the first support block, thereby realizing automatic installation of the carrying plate, recovery of the carrying plate and unloading.

[0022] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.
[0023] like Figures 1 to 7As shown, this embodiment of the invention provides a scraper conveyor for coal mining, including two first support mechanisms 1. Thin belts 2 are symmetrically sleeved on the front and rear sides of the two first support mechanisms 1. A reinforcing wire is provided in the middle of the thin belt 2. The reinforcing wire is made of a high-strength, low-ductility material, specifically steel wire. This increases the strength of the thin belt 2 while reducing its ductility, thus preventing excessive bending due to excessive pressure when the small-diameter rubber thin belt 2 carries a large amount of coal-carrying load plates 17, which could lead to its collapse. Plastic deformation and fracture reduce the service life of the thin strip 2. Multiple conical teeth 201 are fixedly installed at equal intervals on the outer curved surface of the thin strip 2. The top of each conical tooth 201 is conical. A collection shell 3 is fixedly installed on the rear right side of the left first support mechanism 1. A first slot 301 is opened at the bottom front of the collection shell 3, and the bottom surface of the first slot 301 is flush with the inner curved surface of the bottom of the thin strip 2. A second slot 302 is opened at the top of the collection shell 3. Pressure plates 303 are symmetrically fixedly installed at the upper front of the collection shell 3. The pressure plates 303 are symmetrically arranged... The second slot 302 is located on both sides, thus guiding the loading plate 17 pushed out from the second slot 302 and preventing the loading plate 17 from shifting left and right, thereby preventing the top of the carrying rod 1306 from falling off. A first mounting base 4 is fixedly installed at the bottom front of the housing 3. A first support block 5 is fixedly installed on the upper surface of the first mounting base 4 near the housing 3. The first support block 5 is located in the middle of the two thin strips 2. The upper surface of the first support block 5 is flush with the inner side of the bottom of the thin strip 2. The upper surface of the first mounting base 4 is far away from the housing 3. A side plate 6 is fixedly installed on the side. A first guide rail 7 is fixedly installed on the left side behind the side plate 6. The first guide rail 7 is fixedly connected to the collection shell 3. A second guide rail 8 is fixedly installed on the right side behind the side plate 6. A first push plate 9 is slidably sleeved between the first guide rail 7 and the second guide rail 8. A drive mechanism 10 is provided between the first push plate 9 and the collection shell 3. A feeding mechanism 11 is provided between the drive mechanism 10 and the rear of the collection shell 3. A second support mechanism 13 is provided at the front of the collection shell 3. A discharge mechanism 14 is provided in the middle of the rear first support mechanism 1.
[0024] like Figure 2 and Figure 3 As shown, the first support mechanism 1 on the left includes two shaft plates 101. Three belt shafts 102 are equidistantly arranged on the middle circumference of the two shaft plates 101. Clamping rings 103 are symmetrically fixedly sleeved on the front and rear sides of the curved surfaces of the three belt shafts 102. Two thin belts 2 are respectively sleeved in the middle of the two front and two rear clamping rings 103, so as to avoid the thin belts 2 from shifting during rotation, which would increase the distance between the two thin belts 2 and cause the load plate 17 to fall off the two thin belts 2. A driving component 104 is fixedly installed on the front of the front shaft plate 101. The output shaft of the driving component 104 is fixedly connected to the belt shaft 102 on the left.
[0025] like Figure 4As shown, a rubber pad 15 is fixedly installed at the bottom of the inner cavity of the housing 3, and a block 16 that slides and engages with the housing 3 is fixedly installed at the top of the rubber pad 15. Multiple sets of carrying plates 17 that slide and engage with the housing 3 are arranged on the upper surface of the block 16. The carrying plates 17 are made of high-strength, lightweight materials, such as PP or TPX plastic, to reduce their weight and decrease the load on the drive unit 104 and the wasted energy consumption during long-distance transportation. The distance between the bottom surface of the slot 301 and the upper surface of the block 16 is between one-third and one-half the thickness of the carrier plate 17. Both the front and rear ends of the carrier plate 17 are chamfered, and both the front and rear ends of the carrier plate 17 are equally spaced with slots, so that the conical teeth 201 on the outer side of the thin belt 2 can limit the carrier plate 17 through the slots, so as to prevent the carrier plate 17 from falling off the thin belt 2 when the thin belt 2 drives the carrier plate 17 to accelerate, decelerate, move upward or downward.
[0026] like Figure 1 , Figure 2 and Figure 5 As shown, the drive mechanism 10 includes a hydraulic rod 1001, which is fixedly sleeved on the bottom of the housing 3. A middle block 1002 is fixedly installed on the front of the telescopic end of the hydraulic rod 1001. A connecting rod 1003 is fixedly installed on the left end of the middle block 1002. The connecting rod 1003 passes through the bottom of the housing 3 and slides through the housing 3. The contact surface between the connecting rod 1003 and the housing 3 is a smooth surface, thereby reducing the frictional resistance between the connecting rod 1003 and the housing 3, reducing the load when the hydraulic rod 1001 drives the connecting rod 1003 to move back and forth through the middle block 1002, and reducing the energy consumption of the connecting rod 1003. A connecting block 1004 is fixedly installed on the front end of the connecting rod 1003. The top end of the connecting block 1004 is fixedly installed on the side of the lower surface of the second guide rail 8 away from the housing 3. A vertical rod 1005 is fixedly installed on the rear end of the connecting rod 1003.
[0027] like Figure 1 and Figure 2As shown, the feeding mechanism 11 includes a second mounting base 1101, which is fixedly mounted on the upper part of the rear of the housing 3. The upper surface of the second mounting base 1101 is flush with the bottom surface of the second slot 302, so that the second push plate 1103 can slide smoothly through the second slot 302 into the interior of the housing 3, avoiding jamming of the second push plate 1103. Slide rails 1102 are symmetrically provided on the left and right sides of the second mounting base 1101, and a second slide rail 1102 is slidably sleeved in the middle of the two slide rails 1102. Two push plates 1103 are symmetrically fixedly mounted with limiting shafts 1104 on the side away from the housing 3. Limiting blocks 1107 are fixedly mounted on the rear ends of the two limiting shafts 1104. Elastic elements 1105 are sleeved in the middle of the two limiting shafts 1104. The elastic elements 1105 are fixedly connected to the second push plates 1103. A sleeve block 1106 is fixedly mounted on the end of the elastic element 1105 away from the second push plates 1103. The sleeve block 1106 is slidably sleeved with the limiting shafts 1104.
[0028] like Figure 1 As shown, the second support mechanism 13 includes a third mounting plate 1301, which is fixedly installed in the middle of the front of the first support mechanism 1 on the left. A water tank 1302 is fixedly installed on the side of the upper surface of the third mounting plate 1301 away from the housing 3. Multiple weights 1303 are slidably arranged in the middle of the water tank 1302. A connecting pipe 1304 is fixedly installed at the bottom of the water tank 1302 near the housing 3. A sleeve 1305 is fixedly installed at the end of the connecting pipe 1304 near the housing 3. The sleeve 1305 is located in the middle of the two thin belts 2. A carrier rod 1306 is slidably sleeved in the middle of the sleeve 1305. The weights 1303 are made of high-density material and can be made of solid steel, thereby increasing the pressure when the carrier rod 1306 moves downward and increasing the coal loading capacity of the load plate 17 above the carrier rod 1306. In use, the single load of the load plate 17 can be adjusted by increasing or decreasing the number of weights 1303.
[0029] like Figure 2 , Figure 4 and Figure 7As shown, the unloading mechanism 14 includes a fourth mounting plate 1401, which is fixedly installed at the bottom left side of the first support mechanism 1 on the right. A second support block 1402 is fixedly installed in the middle of the upper surface of the fourth mounting plate 1401. The height of the upper surface of the second support block 1402 is the same as the height of the inner side of the bottom of the thin strip 2. The front side of the upper surface of the fourth mounting plate 1401 is fixedly installed on a second side plate 1403. The rear of the second side plate 1403 slides in contact with the front of the front thin strip 2. The height of the second side plate 1403 is greater than the height of the inner side of the bottom of the thin strip 2. A fifth mounting plate 1404 is fixedly installed in the middle of the right side of the first support mechanism 1 on the right. A sleeve 1405 is fixedly installed in the middle of the upper surface of the fifth mounting plate 1404. A sleeve rod 1406 is slidably sleeved in the middle of the sleeve 1405. An inclined block 1 is fixedly installed at the top of the sleeve rod 1406. 407, the rear side of the upper surface of the inclined block 1407 is provided with an inclined surface, the edge of the inclined surface of the upper surface of the inclined block 1407 is close to the front side of the inclined block 1407, the upper surface of the inclined block 1407 is a smooth plane, so that the loading plate 17 on the upper surface of the inclined block 1407 can more easily slide into the interior of the unloading box 1412. The upper surface of the fifth mounting plate 1404 is fixedly installed with a hydraulic box 1408. The middle part of the hydraulic box 1408 is slidably sleeved with a stopper 1409. The height of the stopper 1409 is greater than the height of the inclined block 1407. The front side of the stopper 1409 is fixedly installed with a sealing plate 1410. The sealing plate 1410 is slidably sleeved with the hydraulic box 1408. The right side of the front of the hydraulic box 1408 is fixedly installed with a middle tube 1411. The left end of the middle tube 1411 is fixedly connected to the bottom of the second side plate 1403. The rear side of the right first support mechanism 1 is fixedly installed with the unloading box 1412.
[0030] Working principle:
[0031] Before use, first start the drive unit 104. The output shaft of the drive unit 104 drives the belt shaft 102 fixed to it to rotate. The belt shaft 102 drives the thin belt 2 to rotate. The thin belt 2 drives the inner belt shaft 102 to rotate. The thin belt 2 drives the bevel gear 201 to move. Then start the hydraulic rod 1001 in the forward direction. The telescopic end of the hydraulic rod 1001 pushes the middle block 1002 to move forward. The middle block 1002 drives the connecting rod 1003 to move forward. The connecting rod 1003 drives the connecting block 1004. Moving forward, the connecting block 1004 drives the first push plate 9 to move forward along the first guide rail 7 and the second guide rail 8 and fit tightly against the side plate 6. At the same time, the forward-moving connecting rod 1003 drives the vertical rod 1005 to move forward. The vertical rod 1005 drives the sleeve block 1106 to move forward along the limiting shaft 1104. At this time, the sleeve block 1106 passes through the elastic element 1105, the second push plate 1103 and the loading plate 17 in the inner cavity of the left collection shell 3 in sequence to squeeze the loading plate 17 above the loading rod 1306 and press it tightly against the back of the water tank 1302. At the same time, the elastic element 1105 is squeezed and contracted by the sleeve block 1106.
[0032] The mined coal is then inverted onto the upper surface of the load plate 17 at the top of the load rod 1306. As the amount of coal on the upper surface of the load plate 17 increases, the downward pressure on the load rod 1306 increases. When the weight of the coal on the upper surface of the load plate 17 exceeds the weight of the weight block 1303, the load plate 17 and the coal on its upper surface squeeze the load rod 1306 downwards. The load rod 1306 squeezes the hydraulic fluid at the bottom of the inner cavity of the sleeve 1305, which flows into the bottom of the inner cavity of the water tank 1302 through the connecting pipe 1304, pushing the weight block 1303 upwards. At the same time, the load plate 17 and the coal on its upper surface follow the load rod 1306 downwards. When the lower surface of the load plate 17 contacts the conical teeth 201 on the upper surface of the thin belt 2, the conical teeth 201 and the load plate... When relative sliding occurs at 17, the conical teeth 201 insert into the slots on the front and rear sides of the carrying plate 17. The conical teeth 201, which move with the thin belt 2, pull the carrying plate 17 to move to the right with the coal ore until the bottom surface of the carrying plate 17 is completely separated from the top of the carrying rod 1306. At this time, the pressure of the carrying rod 1306 when moving can be controlled by increasing or decreasing the number of weights 1303. This adjusts the amount of coal ore transported on the upper surface of a single carrying plate 17 each time. Thus, while ensuring that the coal ore above the carrying plate 17 does not slip, when the coal ore density is high, the number of weights 1303 can be increased to increase the coal ore transport volume. When the coal ore density is low, the number of weights 1303 can be decreased to prevent the coal ore above the carrying plate 17 from accumulating too high and slipping.
[0033] When the load plate 17 above the load rod 1306 is completely disengaged from the top of the load rod 1306, the compressed elastic element 1105 recovers, pushing the second push plate 1103 forward. The second push plate 1103 drives the limiting shaft 1104 to slide forward along the sleeve block 1106 until the limiting block 1107 contacts the sleeve block 1106. The second push plate 1103 then pushes the load plate 17 inside the housing 3 that is in contact with it forward. The forward-moving load plate 17 moves along the second slot 302 to the load rod 1306. At the top of 306, the hydraulic rod 1001 is then activated in reverse. The telescopic end of the hydraulic rod 1001 drives the middle block 1002 to move rearward. The middle block 1002 drives the connecting rod 1003 to move rearward. The connecting rod 1003 drives the connecting block 1004 to move rearward. The connecting block 1004 drives the first push plate 9 to move rearward. The first push plate 9 presses the load plate 17 above the first support block 5 to move rearward. The rearward-moving load plate 17 presses the square block 16 inside the housing 3 downward through the first slot 301. The block 16 compresses the rubber pad 15 to shrink and inserts into the housing 3, thereby automatically inserting the retracted load plate 17 from the upper surface of the first support block 5 into the middle of the housing 3. Simultaneously, the connecting rod 1003 moves rearward, driving the vertical rod 1005 to move rearward. The vertical rod 1005 drives the sleeve block 1106 to move rearward, which in turn pushes the limiting block 1107 to move rearward. The limiting block 1107 then drives the limiting shaft 1104 to move rearward, which in turn drives the second push... Plate 1103 moves to the rear side, and the second push plate 1103 disengages from the inner cavity of the housing 3. At this time, the elastic element 1105 is in a relaxed state, and the carrying plates 17 inside the housing 3 re-contact each other. Then, the hydraulic rod 1001 is activated in the forward direction, so that the first push plate 9 fits against the side plate 6. The sleeve block 1106, through the second push plate 1103, the carrying plate 17 inside the housing 3, and the carrying plate 17 on the upper part of the carrying rod 1306, re-squeezes the elastic element 1105 to contract, thereby realizing the automatic installation and recycling of the carrying plate 17.
[0034] When the thin belt 2 and the conical teeth 201 move the carrying plate 17 to the upper surface of the inclined block 1407, the conical teeth 201, moving to the right, drive the carrying plate 17 to push the stopper 1409 to the right. The stopper 1409 compresses the hydraulic oil at the bottom of the hydraulic tank 1408 and flows through the middle pipe 1411 into the bottom of the sleeve 1405. The hydraulic oil flowing into the bottom of the sleeve 1405 pushes the inclined block 1407 upward, and the upward-moving inclined block 1407 pushes the carrying plate 17 to the right. The load plate 17 moves upward until it disengages from the bevel tooth 201. Under the action of the inclined surface of the inclined block 1407, the load plate 17 on the upper surface of the inclined block 1407 tilts backward. The tilted load plate 17 carries the coal ore and slides into the unloading box 1412 and flips over, causing the coal ore to detach from the upper surface of the load plate 17. Then the load plate 17 slides from the opening at the bottom of the unloading box 1412 onto the inner side of the bottom of the thin belt 2, and is finally transported by the thin belt 2 to the upper surface of the first support block 5.
