TECHNICAL FIELD
[0001] The present application belongs to the technical field of scraper conveyors, and particularly relates to a scraper conveyor for coal mining. BACKGROUND
[0002] A coal mine is an area where human beings mine coal resources in a coal-rich mining area. It is generally divided into underground coal mines and open-pit coal mines. When the coal seam is far from the ground surface, a tunnel is generally excavated underground to mine coal, which is an underground coal mine. A scraper conveyor is the core transport equipment of a fully-mechanized coal mining face, and bears the dual functions of coal transportation and a track for a coal mining machine. The mainstream scraper conveyor currently comprises a machine head driving part, a scraper chain, a middle trough, a machine tail tensioning part, etc. The chain form adopts a round link chain or a compact chain, and a double-side chain, a single middle chain or a double middle chain arrangement form is adopted. The scraper is connected with the chain to realize synchronous movement in the machine cabin.
[0003] For the scraper conveyor, when material is transported, the material can be pushed out of the material inlet to the discharge port by moving the scraper in the cabin wall. In this process, since the scraper is not completely attached to the cabin wall, part of the material will adhere to the cabin wall during the pushing process. Generally, a scraper strip is connected behind the scraper to move the scraper strip to wipe the cabin wall. However, due to the stickiness of the material, the wiping action alone has limited cleaning ability for the cabin wall, and the scraper strip needs to be separately disassembled and assembled when cleaning is not required, which is a relatively cumbersome process.

The technical solutions of the present application are described in detail below in conjunction with the embodiments and drawings, but the protection scope is not limited thereto.
[0035] As shown in Fig. Figure 1 The present application provides a coal mining with scraper conveyor, which comprises a conveyor cabin 1, a conveying cavity is arranged on the upper side inside the conveyor cabin 1, a group of chains 5 is arranged on the left and right sides of the conveying cavity respectively, a conveying scraper 7 is fixedly arranged between the two groups of chains 5, a rubber strip carrier plate 14 which can rebound is slidingly arranged on the rear side of the conveying scraper 7 in the vertical direction, and a cleaning rubber strip 19 is arranged at the lower end of the rubber strip carrier plate 14; a sliding transverse rod 22 is slidingly arranged in the inner side of the left and right sides of the rubber strip carrier plate 14 respectively, and a cabin wall track 40 is fixedly arranged on the inner wall of the left and right sides of the conveying cavity; when the two sliding transverse rods 22 on the rubber strip carrier plate 14 are extended outward and inserted into the cabin wall tracks 40 on the left and right sides, the lower end of the cleaning rubber strip 19 keeps sliding contact with the inner bottom surface of the conveying cavity; when the two sliding transverse rods 22 on the rubber strip carrier plate 14 are retracted inward, the sliding transverse rods 22 are separated from the cabin wall tracks 40, the rubber strip carrier plate 14 rebounds upward, and the lower end of the cleaning rubber strip 19 is separated from the inner bottom surface of the conveying cavity.
[0036] An upward feeding bin 2 is fixed on the front upper side of the conveyor cabin 1, and a downward discharging bin 3 is fixed on the rear lower side of the conveyor cabin 1. A driving shaft is rotatably arranged inside the rear end of the conveyor cabin 1, and a driving sprocket is fixedly sleeved on the outer side of each end of the driving shaft. A driven shaft is rotatably arranged inside the front end of the conveyor cabin 1, and a driven sprocket is fixedly sleeved on the outer side of each end of the driven shaft. Two sets of chains 5 are sleeved between the driving sprockets and the driven sprockets on both sides. A driving mechanism 4 is fixed on the outer side of the rear end of the conveyor cabin 1, and the output shaft of the driving mechanism 4 is fixedly connected with the end of the driving shaft. The driving mechanism 4 drives the driving shaft to rotate, the driving shaft drives the two driving sprockets to rotate, the two driving sprockets drive the two sets of chains 5 to rotate under the cooperation of the two driven sprockets, and the two sets of chains 5 drive the conveying scraper 7 to move inside the conveying cavity from front to rear. The conveying scraper 7 in motion conveys the material inside the conveying cavity from front to rear until the material is discharged outward from the discharging bin 3.
[0037] The conveying scraper 7 is in a circular arc plate structure, and the circular arc groove of the conveying scraper 7 faces the front side. A conveying chain plate 6 is fixedly arranged on the side where the two sets of chains 5 are close to each other, and a scraper reinforcing block 8 is fixedly arranged on the left and right ends of the conveying scraper 7. The conveying chain plate 6 on the same side and the scraper reinforcing block 8 are fixedly connected through a plurality of bolts and nuts, so as to fixedly connect the conveying scraper 7 with the chains 5 on both sides, and the chains 5 on both sides drive the conveying scraper 7 to move synchronously. Since the conveying scraper 7 is in a circular arc plate structure, the material can be better concentrated in front of the conveying scraper 7 during the movement of the conveying scraper 7, so that the gathering capacity of the conveying scraper 7 for the material is stronger, and thus the conveying efficiency of the conveying scraper 7 is improved.
[0038] A main bin plate 10 is fixedly arranged on the rear side of the conveying scraper 7, a main bin cavity 11 is arranged inside the main bin plate 10, and an inner cavity sliding block 12 is slidably arranged inside the main bin cavity 11 in the vertical direction. A vertical reset spring 13 is arranged inside the main bin cavity 11, the upper end of the reset spring 13 is fixedly connected with the inner top surface of the main bin cavity 11, and the lower end of the reset spring 13 is fixedly connected with the upper end surface of the inner cavity sliding block 12. A plate reinforcing strip 15 is fixedly arranged on the upper end of the rubber strip carrier plate 14, and the bolts are screwed with the outer side surface of the inner cavity sliding block 12 after penetrating through the plate reinforcing strip 15, so as to fixedly connect the rubber strip carrier plate 14 with the inner cavity sliding block 12, and the rubber strip carrier plate 14 slides synchronously with the inner cavity sliding block 12.
[0039] An arc-shaped inclined baffle plate 16 is fixedly arranged on the upper end of the rear side of the conveying scraper 7, and the upper end of the arc-shaped inclined baffle plate 16 is inclined forward. An assembly bottom plate 17 is fixedly arranged on the lower end of the arc-shaped inclined baffle plate 16, two vertically bottom plate insertion columns 18 which are symmetrical left and right are fixedly arranged on the lower end surface of the assembly bottom plate 17, and an inner side fixed hole is arranged on the outer side surface of the bottom plate insertion column 18 along the radial direction of the bottom plate insertion column 18. An upper end of the assembly main warehouse plate 10 is fixedly arranged with a functional top plate 9, and a vertical top plate longitudinal hole 41 is arranged on the upper end surface of the functional top plate 9 left and right respectively. Two horizontal top plate transverse holes 42 which are symmetrical left and right are arranged on the rear side of the functional top plate 9, and the inner side end of the top plate transverse hole 42 is in communication with the same side top plate longitudinal hole 41. The two bottom plate insertion columns 18 of the lower end of the assembly bottom plate 17 are respectively inserted into the inside of the two top plate longitudinal holes 41 of the functional top plate 9, the inner side fixed hole of the bottom plate insertion column 18 corresponds to the top plate transverse hole 42 of the functional top plate 9, two locking bolts are screwed with the inner side fixed holes of the two bottom plate insertion columns 18 after passing through the two top plate transverse holes 42 of the functional top plate 9, so as to fix the arc-shaped inclined baffle plate 16 on the upper end of the rear side of the conveying scraper 7. The arc-shaped inclined baffle plate 16 is suitable for the scraper conveyor which is placed in an inclined state after being combined with the conveying scraper 7. When the scraper conveyor is inclined at a large angle with the horizontal plane, the conveying capacity of the conveying scraper 7 to the material will be weakened, the material will be separated from the upper end of the inclined conveying scraper 7, and then the material conveying efficiency will be reduced. At this time, through the connection of the arc-shaped inclined baffle plate 16 and the conveying scraper 7, the top area of the conveying scraper 7 can be shielded, and then the conveying effect of the material is enhanced.
[0040] Two lateral horizontal plate horizontal holes 20 are respectively arranged on the lateral sides of the left and right sides of the rubber strip carrier plate 14, and two sliding horizontal rods 22 are arranged in the two plate horizontal holes 20 along the lateral horizontal direction. A lateral horizontal moving horizontal hole 21 is arranged on the rear side wall of each plate horizontal hole 20. A sliding plate is fixedly arranged at the inner side of one end of the sliding horizontal rod 22, and the sliding plate extends to the outside of the rear end of the rubber strip carrier plate 14 through the moving horizontal hole 21. A moving external block 23 is fixedly arranged at the outer side of one end of the sliding plate, and a pushing positioning plate 24 is rotatably arranged in the moving external block 23. An arc-shaped spring part 25 is arranged between the pushing positioning plate 24 and the moving external block 23. A positioning plate hole 27 is arranged on the pushing positioning plate 24. Two positioning insertion plates 26 are arranged on the rear end of each plate horizontal hole 20, one of which is fixedly arranged on the rubber strip carrier plate 14, and the other of which is slidably arranged on the rubber strip carrier plate 14 along the lateral horizontal direction. A fixed plate is arranged between the two positioning insertion plates 26, and the fixed plate is fixedly arranged on the rubber strip carrier plate 14. A lateral horizontal transverse spring 229 is fixedly arranged between the fixed plate and the positioning insertion plate 26 close to the hole of the plate horizontal hole 20.
[0041] Due to the arc spring part 25 arranged between the poking positioning plate 24 and the moving external block 23, the poking positioning plate 24 is in vertical state under the resilience of the arc spring part 25. When the sliding horizontal rod 22 is located inside the loading plate horizontal hole 20, the positioning plate hole 27 on the poking positioning plate 24 is sleeved outside the positioning plug plate 26 at the side away from the hole opening of the loading plate horizontal hole 20, and the poking positioning plate 24 and the sliding horizontal rod 22 are limited by the positioning plug plate 26 at the side away from the hole opening of the loading plate horizontal hole 20, so as to prevent the sliding horizontal rod 22 from moving to the outside of the loading plate horizontal hole 20. When it is needed to extend the sliding horizontal rod 22 to the outside of the loading plate horizontal hole 20, the poking positioning plate 24 is turned upward, so that the positioning plate hole 27 on the poking positioning plate 24 is separated from the positioning plug plate 26 at the side away from the hole opening of the loading plate horizontal hole 20, and the arc spring part 25 is compressed in this process. Then the poking positioning plate 24 is slid toward the hole opening side of the loading plate horizontal hole 20, and the poking positioning plate 24 drives the sliding horizontal rod 22 to slide toward the outside of the loading plate horizontal hole 20 through the moving external block 23 and the sliding plate, until the outside end of the sliding horizontal rod 22 extends to the outside of the hole opening of the loading plate horizontal hole 20. At this time, the poking positioning plate 24 is turned downward under the resilience of the arc spring part 25, until the positioning plate hole 27 on the poking positioning plate 24 is sleeved outside the positioning plug plate 26 at the side close to the hole opening of the loading plate horizontal hole 20. Since the positioning plug plate 26 at the side close to the hole opening of the loading plate horizontal hole 20 is slidably arranged on the fixed plate through the horizontal spring 229, the positioning plug plate 26 at the side close to the hole opening of the loading plate horizontal hole 20 can drive the sliding horizontal rod 22 to slide inside the loading plate horizontal hole 20, but the outside end of the sliding horizontal rod 22 is always located outside the hole opening of the loading plate horizontal hole 20 in the sliding process.
[0042] Two cleaning rubber strips 19 are arranged at the lower end of the rubber strip loading plate 14, and the cleaning rubber strips 19 are located in the vertical plane in the left-right direction.

An adjusting push plate 223 is slidably arranged in the vertical direction inside the crossbar top groove 222, and a contact inclined surface is arranged at the upper end face of the adjusting push plate 223 near the side edge of the walking roller 221. A left-right horizontal push plate connecting rod 224 is arranged inside the mounting cavity of the sliding crossbar 22, one end of the push plate connecting rod 224 is fixedly connected with the lower end of the adjusting push plate 223, and the other end of the push plate connecting rod 224 extends to one end of the mounting cavity away from the walking roller 221. A plurality of vertical abutting springs 226 are arranged inside the mounting cavity of the sliding crossbar 22, the plurality of abutting springs 226 are equidistantly arranged along the axis of the sliding crossbar 22, the lower end of the abutting spring 226 is fixedly connected with the inner bottom surface of the mounting cavity of the sliding crossbar 22, the upper end of the abutting spring 226 is fixedly connected with the lower end face of the push plate connecting rod 224, and the abutting spring 226 is in contact with the inner top surface of the mounting cavity through the elastic force of the abutting spring 226.

[0045] A rubber long strip 32 is fixedly arranged on the rear end surface of the rubber strip carrier plate 14, and is located at the rear side of the two groups of cleaning rubber strips 19 and extends along the left-right direction. Two groups of avoiding grooves are arranged on the rubber long strip 32, and are respectively located at the two push positioning plates 24 and the two groups of positioning plug plates 26, so as to prevent the interference caused by the action of the two push positioning plates 24.

[0047] The working principle of the present application is as follows:
[0048] When the scraper conveyor is conveying materials, the inner part of the conveyor cabin 1 is not cleaned. Therefore, the two sliding cross bars 22 are located in the two carrier plate cross holes 20, the reset springs 13 are in a free rebound state, the sliding cross bars 22 are separated from the cabin wall track 40, at this time, the cleaning rubber strips 19 and the rubber long strip 32 are all at the highest position, and the lower ends of the cleaning rubber strips 19 and the rubber long strip 32 are spaced apart from the inner bottom surface of the conveying cavity. At the same time, the two auxiliary rubber strips 29 are detached from the cleaning rubber strips 19.
[0049] When the scraper conveyor finishes conveying the material, the inside of the conveyor cabin 1 needs to be cleaned. First, hold the two toggle positioning plates 24 and turn them upward, so that the positioning plate holes 27 on the two toggle positioning plates 24 are detached from the positioning plug plates 26 on the sides of the hole openings of the two plate cross holes 20. In this process, the arc-shaped spring parts 25 are compressed. While turning the two toggle positioning plates 24 upward, pull them downward, and through the two toggle positioning plates 24, drive the rubber strip plate 14 and the cleaning rubber strips 19 and the rubber strips 32 to move downward as a whole, so that the reset springs 13 are stretched, until the two sliding cross bars 22 inside the rubber strip plate 14 move downward to the same height as the cabin wall tracks 40 on the two sides, at which time the rubber inclined strip parts 33 and the rubber pressing strip 35 at the lower end of the rubber strips 32 are in contact with the inside bottom surface of the conveying cavity.
[0050] Then slide the two toggle positioning plates 24 toward the hole opening sides of the plate cross holes 20, and through the moving external blocks 23 and the sliding plates, the toggle positioning plates 24 drive the sliding cross bars 22 to slide toward the outside of the plate cross holes 20, until the outer ends of the two sliding cross bars 22 respectively extend to the outside of the hole openings of the two plate cross holes 20. At this time, the walking rollers 221 at the outer ends of the two sliding cross bars 22 are inserted into the inside of the cabin wall tracks 40, and the walking rollers 221 are in contact with the wave-shaped guide rails 228 inside the cabin wall tracks 40. In the process of inserting the walking rollers 221 into the inside of the cabin wall tracks 40, the contact inclined surfaces at the upper ends of the adjusting toggle plates 223 inside the sliding cross bars 22 are in contact with the inside top surfaces of the cabin wall tracks 40, so that the adjusting toggle plates 223 are pressed downward into the cross bar top grooves 222, the adjusting toggle plates 223 drive the toggle plate connecting rods 224 to move downward synchronously, the toggle plate connecting rods 224 drive the lower end cleaning rubber strips 19 to move downward synchronously through the toggle plate vertical rods 225, until the front rubber friction blocks 30 and the rear rubber friction blocks 31 at the lower ends of the two cleaning rubber strips 19 are in contact with the inside bottom surface of the conveying cavity.
[0051] Then turn the two toggle positioning plates 24 downward under the rebounding force of the arc-shaped spring parts 25, until the positioning plate holes 27 on the two toggle positioning plates 24 are respectively sleeved outside the two positioning plug plates 26 near the hole opening sides of the plate cross holes 20.
[0052] Then install a secondary rubber strip 29 on each of the two cleaning rubber strips 19, and the mutually distal ends of the two secondary rubber strips 29 are respectively in sliding contact with the inner walls on the left and right sides of the conveying cavity.
[0053] Then the control driving mechanism 4 starts to run, the two sides of the chain 5 drive the conveying scraper 7 to move again, the conveying scraper 7 drives the rubber strip carrier plate 14 and the cleaning rubber strip 19, the rubber long strip 32 to move synchronously, the front side rubber friction block 30 and the rear side rubber friction block 31 at the lower end of the cleaning rubber strip 19 and the rubber inclined strip part 33 and the rubber pressing strip 35 at the lower end of the rubber long strip 32 are scraped and wiped on the inner bottom surface of the conveying cavity in the forward movement, and the two sides of the auxiliary rubber strip 29 are scraped and wiped on the two side inner walls of the conveying cavity.
[0054] Since the positioning plug plate 26 on one side near the hole of the carrier plate transverse hole 20 is slidably arranged on the fixed plate through the transverse spring 229, the positioning plug plate 26 on one side near the hole of the carrier plate transverse hole 20 can drive the sliding transverse rod 22 to slide inside the carrier plate transverse hole 20. When the walking roller 221 at one end outside the sliding transverse rod 22 is in rolling contact with the wave guide rail 228 inside the cabin wall rail 40, the walking roller 221 drives the sliding transverse rod 22 to slide inside the carrier plate transverse hole 20 away from the wave guide rail 228, and the transverse spring 229 drives the sliding transverse rod 22 to slide inside the carrier plate transverse hole 20 towards the wave guide rail 228, so that the sliding transverse rod 22 reciprocally slides left and right inside the carrier plate transverse hole 20, and the reciprocally sliding sliding transverse rod 22 drives the two cleaning rubber strips 19 to reciprocally slide left and right through the lever vertical rod 225, and the two cleaning rubber strips 19 drive the two auxiliary rubber strips 29 to reciprocally slide left and right, thereby enhancing the cleaning effect on the inner bottom surface and the left and right side inner walls of the conveying cavity.
[0055] After cleaning, the two auxiliary rubber strips 29 are removed, then the two pieces of the driving positioning plate 24 are turned upwards, so that the positioning plate hole 27 on the two pieces of the driving positioning plate 24 is separated from the positioning plug plate 26 on one side near the hole of the carrier plate transverse hole 20, and then the two pieces of the driving positioning plate 24 are slid away from the hole of the carrier plate transverse hole 20, the driving positioning plate 24 drives the sliding transverse rod 22 to slide towards the inside of the carrier plate transverse hole 20 through the moving external block 23 and the sliding plate, until the two sliding transverse rods 22 are slid into the two carrier plate transverse holes 20. Then the two pieces of the driving positioning plate 24 are turned downwards, and the positioning plate hole 27 on the two pieces of the driving positioning plate 24 is respectively sleeved outside the positioning plug plate 26 away from one side of the hole of the carrier plate transverse hole 20. Then the two pieces of the driving positioning plate 24 are loosened, and the rubber strip carrier plate 14, the cleaning rubber strip 19 and the rubber long strip 32 start to rise under the rebound force of the reset spring 13, until they return to the initial height.
[0056] It will be apparent to those skilled in the art that the application is not limited to the details of the above-exemplified embodiments and that the present application can be implemented in other particular forms without departing from the spirit or essential characteristics of the present application.
