DETAILED DESCRIPTION

[0029] In order to make the technical means, creative features, objectives and effects achieved by the present invention easy to understand, the present invention is further explained below in conjunction with specific implementation methods.

[0030] like Figures 1 to 7As shown, an ore conveying device described in an embodiment of the present invention comprises a conveyor seat 1; a plurality of fixed seats 11 are fixedly connected to the end of the conveyor seat 1; a first roller 12 is rotatably connected between two of the fixed seats 11; a fixed frame 14 is fixedly connected to both sides of the end of the conveyor seat 1; a second roller 13 is rotatably connected between the fixed frame 14 and the fixed seat 11; a universal joint 15 is installed at one end of the second roller 13 close to the fixed frame 14; a rotating rod 16 is fixedly connected to the top of the universal joint 15, and the rotating rod 16 is rotatably connected to the fixed frame 14; a conveyor belt 17 is installed on the first roller 12 and the second roller 13; a dust reduction mechanism is arranged on the outside of the fixed frame 14, and the dust reduction mechanism is used to reduce dust at the ore conveying position; when mining and conveying ore in a mine, the conveyor seat 1 is firstly built at the ore conveying position of the mine, and a plurality of fixed seats 11 are distributed and installed on the conveyor seat 1, and cooperate with a plurality of fixed frames 14 to fix and support as the frame of the ore conveying device, and the fixed seats The first roller 12 and the second roller 13 are respectively installed on the first roller 12 and the second roller 13 as the transmission parts for ore transportation. The conveyor belt 17 is placed on the outer wall of the first roller 12 and the two second rollers 13 to fit the outer wall. The conveyor belt 17 is used to store and transport the ore. The mined ore is unloaded on the conveyor belt 17. The power source of the ore conveying device drives the conveyor belt 17 for transportation. The power source is driven by a servo motor. The plurality of first rollers 12 and the second rollers 13 roll in contact with the outer wall of the conveyor belt 17 to transport the ore. The ore on the belt 17 is transported over a long distance. The No. 2 roller 13 drives the rotating rod 16 connected to the universal joint 15 to rotate synchronously when rolling. When the rotating rod 16 rotates, it can drive the dust reduction mechanism to operate and spray water mist from the upper position of the conveyor belt 17. The dust reduction mechanism is evenly spaced in multiple groups. The water mist spraying can be set at intervals according to the distance of ore transportation, which has the effect of reducing dust on the transported ore, thereby reducing the diffusion of dust in the mine, reducing the probability of safety hazards to personnel, and ensuring the production capacity of ore mining.

[0031] like Figures 1 to 5 As shown, a plurality of the fixing frames 14 are fixedly connected to the outside with a fixing plate 2; a plurality of the fixing plates 2 are fixedly connected to the outside with a shielding plate 21, and two shielding plates 21 are symmetrically arranged; when the ore is mined and transported, a plurality of the fixing frames 14 are all installed with a fixing plate 2 on the outside, and the shielding plate 21 is fixed to the fixing frames 14 through a plurality of fixing plates 2, and two symmetrically arranged shielding plates 21 are installed above the conveyor belt 17, and the two shielding plates 21 can shield the surrounding of the ore, reduce the range of dust floating when the ore is transported, and at the same time rely on the two shielding plates 21 to block the top of the conveyor belt 17, which can reduce the noise generated when a large amount of ore is transported.

[0032] The dust reduction mechanism includes a support frame 3, a water tank 31, a water pipe 32, an extrusion box 33, a No. 1 flow cylinder 34, a No. 1 spray box 35, a flow control component and an extrusion mechanism; the support frame 3 is fixedly connected to the outside of the fixed frame 14; the water tank 31 is fixedly connected to the end of the support frame 3; the water pipe 32 is fixedly connected to the outside of the support frame 3; the extrusion box 33 is fixedly connected between the baffle plate 21 and the support frame 3, and the water tank 31 can be connected to the extrusion box 33 through the water pipe 32; the No. 1 flow cylinder 34 is fixedly connected to the inner wall of the extrusion box 33; the No. 1 spray box 35 is fixedly connected to the inner wall of the baffle plate 21, and the No. 1 spray box 35 is connected to the No. 1 flow cylinder 34; the flow control component is arranged inside the support frame 3, and the flow control component is used to control the downward flow of water inside the water tank 31; the extrusion mechanism is arranged inside the support frame 3, and the extrusion mechanism is used to Extrusion spraying; when the ore is mined and transported, the ore is placed on the conveyor belt 17 for transportation, and the conveyor belt 17 drives multiple No. 2 rollers 13 to roll. The rotating rod 16 connected to one end of the No. 2 roller 13 by the universal joint 15 rotates on the fixed frame 14, and the rotating rod 16 synchronously drives the flow control component to operate. The water tank 31 is filled with water in advance and fixed on the support frame 3. The downstream water in the water tank 31 enters the flow control component inside the support frame 3. The flow control component controls the downstream speed of the water in the water tank 31. After passing through the flow control component, the water reaches the inside of the extrusion box 33 through the water pipe 32. The water in the extrusion box 33 is squeezed by the extrusion mechanism, and the water temporarily stored in the extrusion box 33 is squeezed through the No. 1 flow cylinder 34 to the No. 1 spray box 35 for spraying. The No. 1 spray box 35 is located above the conveyor belt 17 and sprays water mist, thereby playing the role of spraying and dust reduction on the transported ore and reducing the spread of dust.

[0033] like Figures 1 to 4 As shown, the flow control assembly includes a flow hole 4, a connecting rod 41, a wheel disc 42 and a crescent groove 43; the flow hole 4 is opened inside the support frame 3 near the bottom end of the water tank 31; the connecting rod 41 is fixedly connected to the top of the rotating rod 16; the wheel disc 42 is fixedly connected to the outside of the connecting rod 41, and the wheel disc 42 is located inside the support frame 3; the crescent groove 43 is opened on the wheel disc 42, and the crescent groove 43 is arranged corresponding to the water pipe 32; when the water flowing down the water tank 31 is controlled, the water inside the water tank 31 first falls from the flow hole 4 to the wheel disc 42 At the upper position, the rotating rod 16 drives the wheel 42 outside the connecting rod 41 to rotate. Whenever the crescent groove 43 coincides with the water pipe 32, the water temporarily stored on the wheel 42 can enter the inside of the water pipe 32. Since the cross-sectional shape of the crescent groove 43 is crescent-shaped, the time for the crescent groove 43 to coincide with the water pipe 32 is the time for the wheel 42 to rotate half a circle around the connecting rod 41. When the crescent groove 43 intersects with the water pipe 32, the wheel 42 can block the water inlet of the water pipe 32, thereby controlling the intermittent downstream flow of water in the water tank 31.

[0034] The extrusion mechanism includes an extrusion chamber 5, an orifice plate 51, a short rod 52, a connecting plate 53, an extrusion plate 54, an air guide 55 and a matching component; the extrusion chamber 5 is opened inside the support frame 3; the orifice plate 51 is fixedly connected to the top of the connecting rod 41; the short rod 52 is fixedly connected to the end of the orifice plate 51; the extrusion plate 54 is slidably connected to the inner wall of the extrusion chamber 5; the connecting plate 53 is hinged between the short rod 52 and the extrusion plate 54; the air guide 55 is fixedly connected between the extrusion chamber 5 and the extrusion box 33, and the extrusion chamber 5 can be connected to the extrusion box 33 through the air guide 55; the matching component is arranged inside the extrusion box 33, and the matching component is used to squeeze the water inside the extrusion box 33; when the water temporarily stored in the extrusion box 33 is squeezed and sprayed to reduce dust, the connecting rod 41 is used to drive the orifice plate 51 to rotate, and at this time, part of the water at the flow hole 4 has already flowed down, and reaches the extrusion box 33 through the orifice plate 51 and the crescent groove 43, The short rod 52 on the orifice plate 51 rotates accordingly, and the short rod 52 drives the hinged connecting plate 53 to push the extrusion plate 54, so that the extrusion plate 54 squeezes the gas in the extrusion chamber 5, and the gas in the extrusion chamber 5 is squeezed and sent into the extrusion box 33 through the air guide pipe 55, and the pushing matching component pressurizes and sprays the water temporarily stored in the extrusion box 33, which plays a role in squeezing and controlling the injection of the water in the extrusion box 33. At the same time, the frequency of the extrusion of the gas in the extrusion chamber 5 by the extrusion plate 54 can be adjusted according to the speed at which the conveyor belt 17 drives the No. 2 roller 13 to roll. When a large amount of ore is transported quickly, the conveyor belt 17 drives the No. 2 roller 13 to roll faster. The faster the frequency of the extrusion plate 54 extruding gas injection, the better the effect of spraying water mist to reduce dust. When a small amount of ore is transported slowly, the conveyor belt 17 drives the No. 2 roller 13 to roll slower, and the frequency of the extrusion plate 54 extruding gas injection is also slower, and the injected water mist initially meets the dust reduction effect.

[0035] The matching components include a rubber block 61 and a sliding plate 62; the rubber block 61 is slidably connected to the inner wall of the extrusion box 33; the sliding plate 62 is fixed between the extrusion box 33 and the rubber block 61; when the gas in the extrusion chamber 5 is squeezed into the extrusion box 33, the gas pushes the rubber block 61 to slide down the inner wall of the extrusion box 33, the sliding plate 62 is pulled and stressed, and the rubber block 61 squeezes the water temporarily stored in the extrusion box 33 into the No. 1 flow tube 34, and then the water is sprayed out from the No. 1 spray box 35, which plays the role of spraying water mist to reduce dust around the transported ore.

[0036] like Figures 1 to 4 , Figure 6As shown, the inner wall of the extrusion box 33 is fixedly connected with a No. 2 flow cylinder 7; the inner wall of the baffle plate 21 is fixedly connected with a No. 2 spray box 71, and the No. 2 flow cylinder 7 is communicated with the No. 2 spray box 71; when spraying water mist on the transported ore, the No. 2 flow cylinder 7 is fixed on the side of the extrusion box 33 away from the No. 1 flow cylinder 34, and the No. 2 spray box 71 is installed in an arc shape on the outer wall of the baffle plate 21. After squeezing the water temporarily stored in the extrusion box 33, the water can be sprayed from the No. 1 spray box 35 and the No. 2 spray box 71 respectively, thereby increasing the area of ​​dust reduction around the ore and improving the dust reduction effect in the mine.

[0037] like Figures 1 to 6 As shown, the interior of the No. 1 flow tube 34 is fixedly connected to the No. 1 connecting frame 8; the No. 1 sealing plate 81 is slidably connected to the convex rod of the No. 1 connecting frame 8; the No. 1 elastic member 82 is sleeved on the outer side of the convex rod of the No. 1 connecting frame 8; the No. 2 connecting frame 83 is fixedly connected to the interior of the No. 2 flow tube 7; the No. 2 sealing plate 84 is slidably connected to the convex rod of the No. 2 connecting frame 83; the No. 2 elastic member 85 is sleeved on the convex rod of the No. 2 connecting frame 83; when the No. 1 spray box 35 and the No. 2 spray box 71 are controlled to spray, the No. 2 roller 13 is driven to rotate by the conveyor belt 17 according to the amount of conveyed ore. If the amount of conveyed ore is small, the output power of the servo motor is reduced so that the No. 2 roller 13 rotates too slowly, so that the rubber block 61 can slowly squeeze the water inside the extrusion box 33, and the water can squeeze the No. 1 sealing plate 81 and the No. 2 sealing plate The plate 84 is pressed and slid at the same time, and the No. 1 elastic member 82 and the No. 2 elastic member 85 are squeezed and contracted at the same time. However, since the distance that the No. 2 sealing plate 84 slides to open the inside of the No. 2 flow cylinder 7 is longer than the distance that the No. 1 sealing plate 81 slides to open the No. 1 flow cylinder 34, when the water inside the extrusion box 33 is slowly squeezed, the water will be sprayed out from the No. 1 spray box 35. If the amount of ore transported is large, the output power of the servo motor is increased, so that the speed of the No. 2 roller 13 rotates too fast, so that the rubber block 61 can quickly squeeze the water inside the extrusion box 33, and the water can quickly punch the No. 1 sealing plate 81 and the No. 2 sealing plate 84 at the same time, so that when the water inside the extrusion box 33 is quickly squeezed, the water can be sprayed out from the No. 1 spray box 35 and the No. 2 spray box 71, which plays a role in controlling the spraying of the No. 1 spray box 35 and the No. 2 spray box 71.

[0038] like Figures 1 to 4 , Figure 7As shown, the bottom end of the second spray box 71 is fixedly connected to a fixed block 9; the inner wall of the fixed block 9 is rotatably connected to a hollow rotating rod 91; the end of the hollow rotating rod 91 away from the fixed block 9 is fixedly connected to a hollow roller 92; the outer side of the hollow roller 92 is provided with a plurality of flow holes 93, and the plurality of flow holes 93 can be connected to the second spray box 71 through the hollow roller 92, the hollow rotating rod 91 and the fixed block 9; when the ore is placed on the conveyor belt 17 for transportation, the ore on both sides of the conveyor belt 17 is easily rubbed to produce dust floating due to the vibration of the machine, and the dust floating is generated by the friction. The fixed block 9 is fixed and connected below the No. 2 spray box 71. Part of the water that enters the No. 2 spray box 71 can reach the inside of the hollow roller 92 along the fixed block 9 and the hollow rotating rod 91. As the hollow roller 92 rolls against the surface of the conveyor belt 17, the water inside the fixed block 9 is thrown out from multiple flow holes 93 under the action of centrifugal force, and the water is sprinkled on the edges of both sides of the conveyed ore, thereby reducing the friction of the ore and generating dust. At the same time, relying on the hollow roller 92 to cooperate with the No. 2 rotating roller 13 to roll against the conveyor belt 17, the probability of the conveyor belt 17 conveying ore deviating can be reduced.

[0039] The fixed block 9 is fixedly connected to a fixed rod 94 on the outside; a shovel plate 95 is fixedly connected to the end of the fixed rod 94 away from the fixed block 9, and the shovel plate 95 is attached to the outer wall of the conveyor belt 17; the inner wall of the shovel plate 95 is rotatably connected to a knocking rod 96 through a torsion spring; a No. 1 magnetic block 97 is fixedly connected to the outside of the knocking rod 96; a No. 2 magnetic block 98 is fixedly connected to the outside of the hollow rotating rod 91, and the No. 2 magnetic block 98 and the No. 1 magnetic block 97 can be magnetically attracted when they are close to each other; when the ore is transported, part of the ore is unloaded on the conveyor belt 17 and is easily attached to the edge of the conveyor belt 17, which causes the ore to shake and spill easily during transportation, and two sets of shovel plates 95 are used to cooperate with the fixed rod 94 to be fixed on both sides of the conveyor belt 17 At the edge position, during the process of conveying ore on the conveyor belt 17, the shovel plate 95 is attached to the edge of the conveyor belt 17 for scraping, so as to reduce the adhesion of ore on the edge of the conveyor belt 17 and reduce the probability of ore spilling during transportation. As the hollow roller 92 rolls on the conveyor belt 17, the second magnetic block 98 outside the hollow rotating rod 91 is driven to rotate, and the second magnetic block 98 intermittently attracts the first magnetic block 97. When the first magnetic block 97 is attracted, it drives one end of the knocking rod 96 to knock on the inner wall of the shovel plate 95. After the second magnetic block 98 is away from the first magnetic block 97, the torsion spring drives the knocking rod 96 to reset and knock on the inner wall of the other side of the shovel plate 95 again, thereby realizing intermittent repeated knocking and vibration of the shovel plate 95 to reduce the adhesion of ore on the shovel plate 95.

[0040] Working process: When transporting ore in a mine, first build the conveyor base 1 at the ore conveying position of the mine, and multiple fixed seats 11 are distributed and installed on the conveyor base 1, and multiple fixed frames 14 are used to fix and support the frame of the ore conveying device. The fixed seats 11 are respectively installed with a No. 1 roller 12 and a No. 2 roller 13 as transmission components for ore transportation. The conveyor belt 17 is placed on the outer wall of the No. 1 roller 12 and the two No. 2 rollers 13 to fit. The conveyor belt 17 is used to store and transport the ore. The mined ore is unloaded on the conveyor belt 17. The power source on the ore conveying device drives the conveyor belt 17 for transportation. The power source is a servo motor. The motor drives, and multiple No. 1 rollers 12 and No. 2 rollers 13 roll against the outer wall of the conveyor belt 17 to transport the ore on the conveyor belt 17 over a long distance. When rolling, the No. 2 roller 13 drives the rotating rod 16 connected to the universal joint 15 to rotate synchronously. When the rotating rod 16 rotates, it can drive the dust reduction mechanism to operate, and spray water mist from the upper position of the conveyor belt 17. The dust reduction mechanism is evenly spaced in multiple groups, and the water mist spraying can be set at intervals according to the distance of ore transportation, so as to reduce dust on the transported ore, thereby reducing the diffusion of dust in the mine, reducing the probability of safety hazards to personnel, and ensuring the production capacity of ore mining; when the ore is mined and transported, multiple A fixing plate 2 is installed on the outside of each fixing frame 14, and a shielding plate 21 is fixed on the fixing frame 14 through multiple fixing plates 2. Two symmetrically arranged shielding plates 21 are installed above the conveyor belt 17. The two shielding plates 21 can shield the surrounding of the ore, reduce the range of dust floating when the ore is transported, and rely on the two shielding plates 21 to block the top of the conveyor belt 17, which can reduce the noise generated when a large amount of ore is transported; when the ore is mined and transported, the ore is placed on the conveyor belt 17 for transportation, and the conveyor belt 17 drives multiple No. 2 rollers 13 to roll, and the rotating rod 16 connected to one end of the No. 2 roller 13 through the universal joint 15 rotates accordingly. On the fixed frame 14, the rotating rod 16 synchronously drives the flow control component to operate. The water tank 31 is filled with water in advance and fixed on the support frame 3. The water flowing down from the water tank 31 enters the flow control component inside the support frame 3. The flow control component controls the downward flow speed of the water in the water tank 31. After passing through the flow control component, the water reaches the inside of the extrusion box 33 through the water pipe 32. The water in the extrusion box 33 is squeezed by the extrusion mechanism. The water temporarily stored in the extrusion box 33 is squeezed through the No. 1 flow cylinder 34 to the No. 1 spray box 35 for spraying. The No. 1 spray box 35 is located above the conveyor belt 17 and sprays water mist, thereby playing the role of spraying and reducing dust on the transported ore and reducing the diffusion of dust;When the water flowing down the water tank 31 is controlled, the water in the water tank 31 first falls from the flow hole 4 to the upper position of the wheel disc 42, and the rotating rod 16 drives the wheel disc 42 outside the connecting rod 41 to rotate. Whenever the crescent groove 43 coincides with the water pipe 32, the water temporarily stored on the wheel disc 42 can enter the inside of the water pipe 32. Since the cross-sectional shape of the crescent groove 43 is a crescent shape, the time for the crescent groove 43 to coincide with the water pipe 32 is the time for the wheel disc 42 to rotate half a circle around the connecting rod 41. When the crescent groove 43 intersects with the water pipe 32, the wheel disc 42 can block the water inlet of the water pipe 32, thereby playing the role of controlling the intermittent downward flow of the water in the water tank 31.

[0041] When the water temporarily stored in the extrusion box 33 is squeezed and sprayed to reduce dust, the connecting rod 41 is used to drive the orifice plate 51 to rotate. At this time, part of the water has flowed down from the flow hole 4 and reaches the extrusion box 33 through the orifice plate 51 and the crescent groove 43. The short rod 52 on the orifice plate 51 rotates accordingly, and the short rod 52 drives the hinged connecting plate 53 to push the extrusion plate 54, so that the extrusion plate 54 squeezes the gas in the extrusion chamber 5. The gas in the extrusion chamber 5 is squeezed and sent into the extrusion box 33 through the air guide pipe 55. The push-matching component pressurizes and sprays the water temporarily stored in the extrusion box 33, which plays a role in squeezing and controlling the injection of the water in the extrusion box 33. At the same time, the frequency of squeezing the gas in the extrusion chamber 5 by the extrusion plate 54 can be adjusted according to the speed at which the conveyor belt 17 drives the second roller 13 to roll. When a large amount of ore is transported quickly, the conveyor belt 17 drives the No. 2 roller 13 to roll faster, the faster the frequency of the squeezing plate 54 squeezing gas injection, the better the effect of spraying water mist to reduce dust. When a small amount of ore is transported slowly, the conveyor belt 17 drives the No. 2 roller 13 to roll slower, the frequency of the squeezing plate 54 squeezing gas injection is also slower, and the sprayed water mist initially meets the dust reduction effect. When the gas in the squeezing chamber 5 is squeezed into the squeezing box 33, the gas pushes the rubber block 61 to slide down the inner wall of the squeezing box 33, the sliding plate 62 is pulled and stressed, and the rubber block 61 squeezes the water temporarily stored in the squeezing box 33 into the No. 1 flow tube 34, and then the water is sprayed out from the No. 1 spray box 35, which plays the role of spraying water mist to reduce dust around the transported ore.

[0042] When spraying water mist on the transported ore, the No. 2 flow cylinder 7 is fixed on the side of the extrusion box 33 away from the No. 1 flow cylinder 34, and the No. 2 spray box 71 is installed in an arc shape on the outer wall of the baffle plate 21. After squeezing the water temporarily stored in the extrusion box 33, the water can be sprayed from the No. 1 spray box 35 and the No. 2 spray box 71 respectively, thereby increasing the dust reduction area around the ore and improving the dust reduction effect in the mine; when controlling the spraying at the No. 1 spray box 35 and the No. 2 spray box 71, the conveyor belt 17 is used to drive the No. 2 roller 13 to rotate according to the amount of transported ore. If the amount of transported ore is small, the output power of the servo motor is reduced so that the speed of the No. 2 roller 13 rotates too slowly, so that the rubber block 61 can slowly squeeze the water inside the extrusion box 33, and the water can simultaneously punch the No. 1 sealing plate 81 and the No. 2 sealing plate 84 Sliding, the No. 1 elastic member 82 and the No. 2 elastic member 85 are squeezed and contracted at the same time, but because the distance that the No. 2 blocking plate 84 slides to open the inside of the No. 2 flow tube 7 is longer than the distance that the No. 1 blocking plate 81 slides to open the No. 1 flow tube 34, when the water inside the extrusion box 33 is slowly squeezed, the water will be sprayed out from the No. 1 spray box 35. If the amount of ore transported is large, the output power of the servo motor is increased, so that the speed of the No. 2 rotating roller 13 is too fast, so that the rubber block 61 can quickly squeeze the water inside the extrusion box 33, and the water can quickly punch the No. 1 blocking plate 81 and the No. 2 blocking plate 84 at the same time, so that when the water inside the extrusion box 33 is quickly squeezed, the water can be sprayed out from the No. 1 spray box 35 and the No. 2 spray box 71, which plays a role in controlling the spraying of the No. 1 spray box 35 and the No. 2 spray box 71;

[0043] When the ore is placed on the conveyor belt 17 for transportation, the ore on both sides of the conveyor belt 17 vibrates with the machine, which easily causes dust to float due to friction. The fixed block 9 is fixed below the No. 2 spray box 71 for communication, and part of the water entering the No. 2 spray box 71 can reach the inside of the hollow roller 92 along the fixed block 9 and the hollow rotating rod 91. As the hollow roller 92 rolls against the surface of the conveyor belt 17, the water inside the fixed block 9 is thrown out from the multiple flow holes 93 under the action of centrifugal force, and the water is sprinkled on the edges of both sides of the conveyed ore, thereby reducing the dust generated by the friction of the ore. At the same time, the probability of the conveyor belt 17 conveying ore deviating can be reduced by relying on the hollow roller 92 to cooperate with the No. 2 rotating roller 13 to roll against the conveyor belt 17; when the ore is transported, part of the ore is easily attached to the edge of the conveyor belt 17 when it is unloaded on the conveyor belt 17, thereby This causes the ore to shake and spill easily during transportation. Two sets of shovel plates 95 are used to cooperate with fixed rods 94 to be fixed at the edge positions on both sides of the conveyor belt 17. In the process of conveying ore by the conveyor belt 17, the shovel plates 95 are attached to the edge of the conveyor belt 17 to scrape and reduce the adhesion of ore on the edge of the conveyor belt 17, thereby reducing the probability of ore spilling during transportation. As the hollow roller 92 rolls on the conveyor belt 17, the second magnetic block 98 outside the hollow rotating rod 91 is driven to rotate, and the second magnetic block 98 intermittently attracts the first magnetic block 97. When the first magnetic block 97 is attracted, it drives one end of the knocking rod 96 to knock on the inner wall of the shovel plate 95. After the second magnetic block 98 is away from the first magnetic block 97, the torsion spring drives the knocking rod 96 to reset and knock on the inner wall of the other side of the shovel plate 95 again, thereby realizing intermittent and repeated knocking and vibration of the shovel plate 95, thereby reducing the adhesion of ore on the shovel plate 95.
