Description

Technical Field

[0001] The invention relates to the technical field of coal recovery from a ramming coke oven coal car, in particular to a coal recovery device from a ramming coke oven coal car. Background Art

[0002] At present, coal briquette is formed on a coal loading car, a coal loading and coke pushing machine or a tamping coal loading and coke pushing integrated machine (SCP), which requires the help of a tamping machine. The feeder is shaken to inject the coking coal inside the coal tower into the tamping coal box in layers. The hammer rod of the tamping machine reciprocates up and down, and the coking coal is tamped into briquette in layers under the action of its own weight and free fall, and then pushed into the coke oven for coking treatment.

[0003] After the crushed coal is rammed into coal cakes, it is necessary to push them from the ramming coal box into the coke oven. However, due to the heavy weight of the coal cakes and the different degrees of ramming in different places, it is inevitable that slag will fall off or even the entire coal cake will collapse. When processing this part of the crushed coal in the existing technology, it is mostly transported to one place through a conveyor, and then recycled and reused in a unified manner. This processing method is more troublesome.

[0004] It should be noted that the above contents belong to the technical knowledge of the inventor and do not necessarily constitute prior art. Summary of the invention

[0005] Based on this, it is necessary to provide a coal recovery device for a ramming coke oven coal car to address the above technical problems.

[0006] In order to achieve the above object, the present invention provides a coal recovery device for a ramming coke oven coal car, comprising: coke oven; A walking tamping coal pusher, comprising a tamping coal box, a conveyor, a storage box, a material elevator, a bucket lifting mechanism, a temporary storage box, a discharge barrel, a rotating discharge mechanism and a vibrating bucket mechanism, wherein the feed end of the conveyor is located between the tamping coal box and the coke oven, the discharge end of the conveyor is located at the top of the storage box, a plurality of bucket lifting mechanisms are installed on the material elevator, the discharge end of the storage box is located directly above the lifting direction of the bucket lifting mechanism, the temporary storage box is installed on one side of the discharge end at the top of the material elevator, the discharge barrel is installed at the bottom of the temporary storage box, the discharge barrel is installed with a rotating discharge mechanism, the output end of the discharge barrel is located above the tamping coal box, and a vibrating bucket mechanism is provided in the material elevator; The bucket lifting mechanism includes a U-shaped frame, a storage hopper, a card slot and a card block. The U-shaped frame is installed on the material hoist. A plurality of card slots are provided on both sides of the storage hopper. Card blocks corresponding to the card slots are installed on both sides of the U-shaped frame. The card blocks are slidably connected to the card slots. Among them, the vibration bucket mechanism includes a gravity plate, an abutment frame, a base, a telescopic support mechanism and a top block. The gravity plate and the abutment frame are rotatably installed in the temporary storage box. The base is hinged on the gravity plate, the telescopic support mechanism is installed on the base, the top block is hinged on the abutment frame, and the output end of the telescopic support mechanism is connected to the top block.

[0007] By adopting the above technical scheme, after the coal cakes in the tamping coal box are pushed out, the broken slag or the whole collapse will fall on the conveyor between the coke oven feeding port, and after being transported by the conveyor, it will be sent to the storage box for storage, and the broken coal in the storage box will fall out from its discharge port after being accumulated to a certain extent, and fall into the bucket lifting mechanism on the material elevator, and can be transported to the temporary storage box by the bucket lifting mechanism, and then the coal in the temporary storage box is transported to the top of the tamping coal box through the rotating discharge mechanism installed in the discharge barrel, so that the fallen broken coal can be transported along with the coal cakes The coal is then fed into the coke oven for coking, so that the crushed coal can be directly recycled and reused; since the diameter of the tamping hammer in the tamping mechanism on the walking tamping coal pusher is slightly smaller than the width of the tamping coal box, there will be loose coal fragments on the top edge of the coal cake, so transporting the crushed coal to the top of the coal cake will not affect its coking; in order to make the crushed coal tamped into coal cakes, the crushed coal needs to contain a certain amount of moisture, so that the crushed coal is easy to adhere to the bucket lifting mechanism, and the telescopic support structure can be supported by a heavier gravity plate that is always perpendicular to the ground when not subject to external force, so that the abutment frame The U-shaped frame is kept perpendicular to the gravity plate, and when the storage hopper slidably connected to the U-shaped frame abuts the abutment frame, the storage hopper can be retracted back into the U-shaped frame through the sliding engagement relationship between the card slot and the card block. When the storage hopper slides to the innermost part of the U-shaped frame, the U-shaped frame begins to exert pressure on the abutment frame driven by the material hoist, causing the abutment frame to start rotating and the telescopic support structure to start shortening. When the abutment frame compresses the telescopic support structure to the shortest, the telescopic support structure begins to exert pressure on the gravity plate, causing it to deflect to a certain extent, thereby enabling The abutment frame passes by the side of the U-shaped frame. At this time, the storage hopper no longer contacts the abutment frame, and collides with the block on the U-shaped frame through the card slot under the action of its own gravity, so that the material in the storage hopper can be vibrated down and fall into the temporary storage box along the curved surface of the previous U-shaped frame; therefore, it is necessary to ensure that the telescopic support mechanism will not be squeezed and rotated by the gravity of the storage hopper, and the gravity plate will not rotate due to its large dead weight before the telescopic support mechanism is compressed to the maximum; the abutment frame is hollow in the middle, and its frame part abuts against the storage hopper.

[0008] Optionally, the walking tamping coal pushing car also includes a pushing plate, a baffle plate, a matching groove, a matching block, a linear actuator, a second linear actuator, a lower pressure frame, a lower pressure groove, a lower pressure block, a spring, a flat material roller, a material returning plate and a control mechanism. The pushing plate and the baffle plate are both slidably connected in the tamping coal box. A matching groove is provided in the pushing plate. The matching groove is slidably connected with a matching block. A linear actuator is installed in the matching groove. The output end of the linear actuator is connected to the matching block. The second linear actuator is installed on the tamping coal box. A lower pressure frame is installed at the output end of the linear actuator. There are several symmetrically arranged lower pressure grooves, in which lower pressure blocks are slidably engaged, and springs are installed in the lower pressure grooves. The output end of the spring is connected to the lower pressure block, and the corresponding lower pressure block is rotatably connected to the same flat material roller. Two symmetrically arranged return plates are installed on the lower pressure frame, and the end of the return plate away from the lower pressure frame abuts against the inner wall of the tamping coal box. Several flat material rollers are distributed in a stepped manner, and the flat material rollers closer to the return plate are higher. The flat material rollers, return plates and matching blocks are all located above the baffle plate, and there is also a control mechanism on the walking tamping coal pusher for controlling the movement of the push plate and the baffle plate.

[0009] By adopting the above technical scheme, the tamping mechanism for tamping the coal cake has an action range between the push plate and the baffle plate, so the return plate will not affect the tamping. When the tamping is completed, the control mechanism removes the baffle plate and starts to control the push plate to push the coal cake out. When pushing out, the linear actuator located above the coal cake drives the matching block in the matching groove during tamping to extend, and pushes the untamped broken coal at the top edge of one end of the coal cake close to the push plate, and it can be retracted after the pushing is completed; and the floating coal at the top edge of the pushed out coal cake is pushed to the middle by the return plate, and then the linear actuator 2 drives several flat rollers on the pressing frame to press down to a suitable height The floating coal on the top of the coal cake and the crushed coal that is collected and re-added are gradually compacted by a number of flat rollers that gradually decrease in height, and the floating coal at one end of the top of the coal cake is pushed by the matching block, so that the coal that is squeezed and accumulated when the flat roller presses the material can be pressed to the part without floating coal pushed out by the matching block. When the pushing plate is pushed to the return plate, the linear actuator 2 drives the lower pressure frame to move upward as a whole; the lower pressure block squeezed by the spring in the lower pressure groove allows the flat roller to bounce up when encountering a thicker coal seam; the flat roller only simply compacts the floating coal and crushed coal to reduce falling, and will not affect the firmness of the coal cake that has been compacted.

[0010] Optionally, a second conveyor is also installed on the walking tamping coal pusher, the discharge end of the discharge cylinder is located on the second conveyor, and the tamping mechanism for tamping the coal cakes is located between the second conveyor and the tamping coal box.

[0011] By adopting the above technical solution, conveyor 2 transports the crushed coal to a position close to the return plate, so that the crushed coal can fall onto the entire coal cake to the greatest extent, and the tamping mechanism is located between conveyor 2 and the tamping coal box, so it will not affect the tamping work.

[0012] Optionally, the rotary discharging mechanism includes a rotary drive device, a screw rod and a spiral blade. The screw rod is rotatably mounted on the discharging barrel, the rotary drive device is mounted on the discharging barrel, the output end of the rotary drive device is transmission-connected to the screw rod, and the spiral blade is mounted on the screw rod.

[0013] By adopting the above technical solution, the spiral blades on the spiral rod are driven by the rotary drive device to transport the crushed coal. The rotary drive device should be connected to the control mechanism signal, so that when the push plate is pushed to a certain position, the rotary drive device stops working to prevent the crushed coal from falling onto the push plate.

[0014] Optionally, a shovel hopper is installed on the top of the storage hopper, and a discharge guide block is installed in the shovel hopper.

[0015] By adopting the above technical solution, the material output from the storage box can be completely guided into the storage hopper through the shovel hopper with the same width as the top of the U-shaped frame. Similarly, when the material in the storage hopper is dumped and output and the hopper is vibrated, the crushed coal can be transported to the temporary storage box through the guiding effect of the discharge guide block and the guiding effect of the previous U-shaped frame.

[0016] Optionally, the telescopic support mechanism includes a sleeve, an intermediate sleeve, a push rod and a second spring. The sleeve is installed on the base, the output end of the push rod is connected to the top block, the intermediate sleeve is slidably connected in the sleeve, the push rod is slidably connected in the intermediate sleeve, and the second spring is installed in the sleeve and the intermediate sleeve, and the output ends of the two second springs are respectively connected to the intermediate sleeve and the push rod.

[0017] By adopting the above technical solution, the telescopic support mechanism has a certain supporting force through the support of two pairs of intermediate sleeves and the top rod by two springs, and the intermediate sleeve is slidably connected in the sleeve, and the top rod is slidably connected in the intermediate sleeve, so that the telescopic support mechanism has retractability, and the multi-stage method of sleeve, intermediate sleeve and top rod is adopted to increase its length.

[0018] Optionally, a top plate and a bottom plate are installed in the temporary storage box, the top plate is arranged in cooperation with the U-shaped frame, and the bottom plate is arranged in cooperation with the vibration bucket mechanism.

[0019] By adopting the above technical solution, the top plate and the bottom plate are matched with the gap of the outer wall of the U-shaped frame, and the top plate and the bottom plate respectively guide and collect the crushed coal that naturally dumps out of the storage hopper and after the hopper is vibrated.

[0020] Optionally, a discharge plate is hinged at the discharge end of the storage box, two L-shaped plates are installed at the bottom of the storage box, the L-shaped plates are abutted against the bottom of the discharge plate, and a lifting block is installed on the side of the U-shaped frame close to the discharge plate; the thickness of the discharge plate is greater than the thickness of the shovel hopper.

[0021] By adopting the above technical scheme, when the lifting block does not abut against the discharge plate and lifts it, that is, the storage hopper is located below the discharge plate, the crushed coal in the storage box can fall into the storage hopper through the discharge plate along an arc parabola; when the lifting block abuts against the discharge plate, the thicker discharge plate can still allow the crushed coal to fall into the storage hopper through the shovel hopper; when the lifting block lifts the discharge plate, no more crushed coal enters the storage hopper, and when the discharge plate is lifted to a certain height, it no longer contacts the lifting block, but rotates downward again according to its own gravity, thereby producing a certain vibration effect on the crushed coal in the storage box at the edge of the discharge plate and the crushed coal adhered to the discharge plate, so that the dropping effect is good and the adhesion of the crushed coal is reduced.

[0022] A telescopic stabilizing rod is installed on the tamping coal box, and the output end of the telescopic stabilizing rod is connected to the lower pressing frame.

[0023] By adopting the above technical solution, the telescopic stabilizer bar plays a role of stabilizing support for the lower pressure frame, and can move up and down with the second linear actuator, thereby avoiding damage to the second linear actuator.

[0024] This technical solution has at least the following beneficial effects: The scattered broken coal is transported by the conveyor and enters the storage box, and then is lifted by the bucket mechanism on the material elevator, and cooperates with the rotating discharging mechanism to transport the broken coal to the coal cakes that have been tamped in the tamping coal box, thereby reducing the complicated process of collecting it, transporting it to the coal storage site, and then transporting it to the traveling tamping coal pusher by the conveyor. The broken coal can be directly recycled and reused and sent to the coke oven for coking, saving manpower and financial resources, and can be modified according to the existing traveling tamping coal pusher to further save costs; The storage hopper in the bucket lifting mechanism is vibrated by the bucket vibrating mechanism to avoid the crushed coal with a certain humidity from sticking to it during recycling, which would result in poor recycling effect. 3. Several flat rollers are used to perform simple compaction on the floating coal on the top of the coal cake and the recycled crushed coal, which reduces the possibility of the floating coal on the top falling off when the coal cake is pushed out.

DETAILED DESCRIPTION

The above structures are directly or indirectly installed on the walking tamping coal pusher 2 and can be driven to move. The conveyor 22 can be a belt conveyor or a scraper, and preferably a scraper with a strong force bearing capacity. The material elevator 24 can be a bucket elevator, and the rotating discharge mechanism 28 can be a spiral discharge device. The feeding end of the conveyor 22 is located between the tamping coal box 21 and the coke oven 1. The discharging end of the conveyor 22 is located at the top of the storage box 23, and a plurality of bucket lifting mechanisms 25 are installed on the material hoist 24. The discharging end of the storage box 23 is located directly above the lifting direction of the bucket lifting mechanism 25. The temporary storage box 26 is installed on one side of the discharging end at the top of the material hoist 24. The discharging cylinder 27 is installed at the bottom of the temporary storage box 26. The discharging cylinder 27 is installed with a rotating discharging mechanism 28. The output end of the discharging cylinder 27 is located above the tamping coal box 21. The material hoist 24 is provided with a vibrating bucket mechanism 29, and also includes a tamping mechanism for tamping coal, which is a prior art and is not shown in the figure; The bucket lifting mechanism 25 includes a U-shaped frame 251, a storage hopper 252, a slot 253 and a block 254. The U-shaped frame 251 is installed on the material lifting machine 24. A plurality of slots 253 are provided on both sides of the storage hopper 252. Blocks 254 corresponding to the slots 253 are installed on both sides of the U-shaped frame 251. The blocks 254 are slidably connected to the slots 253. Among them, the bucket vibration mechanism 29 includes a gravity plate 291, an abutment frame 292, a base 293, a telescopic support mechanism 294 and a top block 295. The telescopic support mechanism 294 is a telescopic structure that can generate a strong abutment support force on the abutment frame 292, such as an electric cylinder or a telescopic rod with a spring installed in it, and the spring can support its output end, etc. The gravity plate 291 and the abutment frame 292 are both rotatably installed in the temporary storage box 26, the gravity plate 291 is hinged with a base 293, the base 293 is installed with a telescopic support mechanism 294, the abutment frame 292 is hinged with a top block 295, and the output end of the telescopic support mechanism 294 is connected to the top block 295; the material hoist 24, the bucket lifting mechanism 25, the rotary discharging mechanism 28, etc. should all be connected through the signal processor signal, so that they can work together when the coal cake is pushed out, and when the coal cake collapses, the other devices all work but the rotary discharging mechanism 28 stops transporting crushed coal into the tamping coal box 21.

[0028] After the coal cakes in the tamping coal box 21 are pushed out, the broken slag or the whole collapse will fall onto the conveyor 22 between the feeding port of the coke oven 1, and after being transported by the conveyor 22, they are sent to the storage box 23 for storage. After the broken coal in the storage box 23 is accumulated to a certain extent, it falls out from its discharge port and falls into the bucket lifting mechanism 25 on the material elevator 24, and can be transported to the temporary storage box 26 by the bucket lifting mechanism 25. Then, the coal in the temporary storage box 26 is transported to the top of the tamping coal box 21 through the rotating discharge mechanism 28 installed in the discharge cylinder 27, so that the fallen broken coal can enter the coke oven 1 together with the coal cakes for coking, so that it can be directly The crushed coal is then recycled for reuse; since the diameter of the tamping hammer in the tamping mechanism on the walking tamping coal pusher 2 is slightly smaller than the width of the tamping coal box 21, there will be loose crushed coal on the top edge of the coal cake, so transporting the crushed coal to the top of the coal cake will not affect its coking; in order to enable the crushed coal to be tamped into coal cakes, the crushed coal needs to contain a certain amount of moisture, so that the crushed coal is easy to adhere to the bucket lifting mechanism 25, and the telescopic support structure 294 can be supported by a heavier gravity plate 291 that is always perpendicular to the ground when not subject to external force, so that the abutment frame 292 remains perpendicular to the gravity plate 291, and when the storage hopper 25 is slidably connected to the U-shaped frame 251 When the material storage hopper 252 abuts against the abutting frame 292, the material storage hopper 252 can be retracted back into the U-shaped frame 251 through the sliding engagement relationship between the card slot 253 and the card block 254. When the material storage hopper 252 slides to the innermost part of the U-shaped frame 251, the U-shaped frame 251 begins to exert pressure on the abutting frame 292 under the drive of the material hoist 24, so that the abutting frame 292 begins to rotate and the telescopic support structure 294 begins to shorten. When the abutting frame 292 compresses the telescopic support structure 294 to the shortest, the telescopic support structure 294 begins to exert pressure on the gravity plate 291, causing it to deflect to a certain extent, so that the abutting frame 292 can be pulled out of the U-shaped frame 251. 251, and the material in the hopper 252 is vibrated down and falls into the temporary storage box 26 along the arc surface of the previous U-shaped frame 251; therefore, it is necessary to keep the telescopic support mechanism 294 from being squeezed and rotated by the gravity of the hopper 252, and the gravity plate 291 will not rotate due to its greater deadweight before the telescopic support mechanism 294 is compressed to the maximum; the abutment frame 292 is hollow in the middle, and its frame portion abuts against the hopper 252.

[0029] In one embodiment, see Figure 7 and Figure 8The walking tamping coal pusher 2 also includes a push plate 201, a blocking plate 202, a matching groove 203, a matching block 204, a linear actuator 205, a linear actuator II 206, a lower pressure frame 207, a lower pressure groove 208, a lower pressure block 209, a spring 210, a flat material roller 211, a material return plate 212 and a control mechanism 213. The linear actuator 205 and the linear actuator II 206 can both be electric cylinders. The control mechanism 213 is a walking tamping coal pusher in the prior art. 2, the mechanism for controlling the movement of the push plate 201 and the baffle plate 202 is not described in detail. The control mechanism 213 for controlling the baffle plate 292 to rotate and move out is not shown in the figure. The push plate 201 and the baffle plate 202 are both slidably connected in the tamping coal box 21. The push plate 201 is provided with a matching groove 203, and the matching groove 203 is slidably connected with a matching block 204. A linear actuator 205 is installed in the matching groove 203, and the output end of the linear actuator 205 is connected to the matching block 2 04 connection, the linear actuator 206 is installed on the tamping coal box 21, the output end of the linear actuator 206 is installed with a lower pressing frame 207, the lower pressing frame 207 is provided with a plurality of symmetrically arranged lower pressing grooves 208, a lower pressing block 209 is slidably connected in the lower pressing groove 208, a spring 210 is installed in the lower pressing groove 208, the output end of the spring 210 is connected to the lower pressing block 209, and the corresponding lower pressing block 209 is rotatably connected with the same flat material roller 211, the lower pressing frame 2 07 are provided with two symmetrically arranged material returning plates 212, one end of the material returning plate 212 away from the lower pressing frame 207 is in contact with the inner wall of the tamping coal box 21, and a plurality of flat material rollers 211 are distributed in a stepped manner, and the flat material rollers 211 closer to the material returning plate 212 are higher, and the flat material rollers 211, the material returning plates 212 and the matching blocks 204 are all located above the material baffle plate 202. There is also a control mechanism 213 on the walking tamping coal pusher 2 for controlling the movement of the material pushing plates 201 and the material baffle plate 202.

[0030] By adopting the above technical solution, the tamping mechanism for tamping the coal cake has an action range between the push plate 201 and the baffle plate 202, so the return plate 212 will not affect the tamping. When the tamping is completed, the control mechanism 213 moves the baffle plate 202 away and starts to control the push plate 201 to push the coal cake out. When pushing out, the linear actuator 205 located above the coal cake drives the matching block 204 in the matching groove 203 during tamping to extend, and pushes the untamped broken coal at the top edge of one end of the coal cake close to the push plate 202, and it can be retracted after the pushing is completed; and the floating coal at the top edge of the pushed coal cake is pushed to the middle by the return plate 212, and then the linear actuator 206 drives several flat rollers 211 on the lower pressing frame 207 to press down to a suitable The floating coal on the top of the coal cake and the crushed coal that is collected and re-added are gradually compacted by a number of flat rollers 211 whose heights are gradually reduced, and a part of the floating coal at one end of the top of the coal cake is pushed by the matching block 204, so that the coal that is squeezed and accumulated when the flat roller 211 presses the material can be pressed to the part without floating coal pushed out by the matching block 204. When the pushing plate 201 is pushed to the returning plate 212, the linear actuator 206 drives the lower pressing frame 207 to move upward as a whole; the lower pressing block 209 squeezed by the spring 210 in the lower pressing groove 208 is used to make the flat roller 211 bounce up when encountering a thicker coal seam; the flat roller 211 only simply compacts the floating coal and crushed coal to reduce falling, and will not affect the firmness of the coal cake that has been compacted.

[0031] In one embodiment, see Figure 2 A conveyor 214 is also installed on the walking tamping coal pusher 2. The conveyor 214 can be a belt conveyor. The discharge end of the discharge cylinder 27 is located on the conveyor 214. The tamping mechanism for tamping coal cakes is located between the conveyor 214 and the tamping coal box 21.

[0032] By adopting the above technical solution, the crushed coal is transported by conveyor 214 to the place close to the return plate 212, so that the crushed coal can fall on the entire coal cake to the greatest extent, and the tamping mechanism is located between conveyor 214 and the tamping coal box 21, so it will not affect the tamping work.

[0033] In one embodiment, the rotary discharging mechanism 28 includes a rotary drive device 281, a screw rod 282 and a spiral blade 283. The rotary drive device 281 can be a motor. The screw rod 282 is rotatably mounted on the discharging barrel 27. The rotary drive device 281 is mounted on the discharging barrel 27. The output end of the rotary drive device 281 is transmission-connected to the screw rod 282, and the spiral blade 283 is mounted on the screw rod 282.

[0034] By adopting the above technical solution, the spiral blade 283 on the spiral rod 282 is driven by the rotary drive device 281 to transport the crushed coal. The rotary drive device 281 should be connected to the signal of the control mechanism 213, so that when the push plate 201 is pushed to a certain place, the rotary drive device 281 stops working to prevent the crushed coal from falling onto the push plate 201.

[0035] In one embodiment, a shovel hopper 2521 is installed on the top of the storage hopper 252 , and a discharge guide block 2522 is installed in the shovel hopper 2521 .

[0036] By adopting the above technical solution, the material output from the storage box 23 can be completely guided into the storage hopper 252 through the shovel hopper 2521 which is the same width as the top of the U-shaped frame 251. Similarly, when the material in the storage hopper 252 is dumped and output and the bucket is vibrated, the crushed coal can be transported to the temporary storage box 26 through the guiding effect of the discharge guide block 2522 and the guiding effect of the previous U-shaped frame 251.

[0037] In one embodiment, see Figure 6 The telescopic support mechanism 294 includes a sleeve 2941, an intermediate sleeve 2942, a push rod 2943 and a spring 2944. The sleeve 2941 is installed on the base 293, the output end of the push rod 2943 is connected to the top block 295, the sleeve 2941 is slidably connected with the intermediate sleeve 2942, the intermediate sleeve 2942 is slidably connected with the push rod 2943, the sleeve 2941 and the intermediate sleeve 2942 are both installed with a spring 2944, and the output ends of the two springs 2944 are respectively connected to the intermediate sleeve 2942 and the push rod 2943.

[0038] By adopting the above technical solution, the telescopic support mechanism 294 has a certain supporting force through the support of the middle sleeve 2942 and the top rod 2943 by two springs 2944, and the middle sleeve 2942 is slidably connected in the sleeve 2941, and the top rod 2943 is slidably connected in the middle sleeve 2942, so that the telescopic support mechanism 294 has telescopicity, and the multi-stage method of the sleeve 2941, the middle sleeve 2942 and the top rod 2943 is adopted to increase its length.

[0039] In one embodiment, a top plate 261 and a bottom plate 262 are installed in the temporary storage box 26 . The top plate 261 is arranged in cooperation with the U-shaped frame 251 , and the bottom plate 262 is arranged in cooperation with the vibration bucket mechanism 29 .

[0040] By adopting the above technical solution, the top plate 261 and the bottom plate 262 are matched with the outer wall of the U-shaped frame 251, and the top plate 261 and the bottom plate 262 respectively guide and collect the crushed coal naturally dumped in the storage hopper 252 and after the hopper is vibrated.

[0041] In one embodiment, see Fig. 9 A discharge plate 231 is hinged at the discharge end of the storage box 23, and two L-shaped plates 232 are installed at the bottom of the storage box 23, the L-shaped plates 232 are abutted against the bottom of the discharge plate 231, and a lifting block 233 is installed on the side of the U-shaped frame 251 close to the discharge plate 231; the thickness of the discharge plate 231 is greater than the thickness of the shovel bucket 2521.

[0042] By adopting the above technical scheme, when the lifting block 233 does not abut against the discharge plate 231 and lifts it, that is, the storage hopper 252 is located below the discharge plate 231, the crushed coal in the storage box 23 can fall into the storage hopper 252 through the discharge plate 231 along the arc parabola; when the lifting block 233 abuts against the discharge plate 231, the thicker discharge plate 231 can still allow the crushed coal to fall into the storage hopper 252 through the shovel hopper 2521; when the lifting block 233 lifts the discharge plate 231, the storage hopper 252 no longer enters the crushed coal, and when the discharge plate 231 is lifted to a certain height, it no longer contacts the lifting block 233, but rotates downward again according to its own gravity, thereby producing a certain vibration effect on the crushed coal in the storage box 23 at the edge of the discharge plate 231 and the crushed coal adhered to the discharge plate 231, so that the dropping effect is good and the adhesion of the crushed coal is reduced.

[0043] In one embodiment, a telescopic stabilizing rod 215 is installed on the tamping coal box 21 , and the output end of the telescopic stabilizing rod 215 is connected to the lower pressure frame 207 .

[0044] By adopting the above technical solution, the telescopic stabilizing rod 215 plays a role of stabilizing and supporting the lower pressure frame 207, and can move up and down with the second linear actuator 206, thereby avoiding damage to the second linear actuator 206.
