Abstract
Description
Technical Field
[0001] This invention relates to coal leveling technology, specifically to an intelligent hydraulic coal leveling device with an automatic control system. Background Technology
[0002] Coal leveler: A coal leveling plate installed on a gantry frame, which is lowered into the car body of the vehicle that needs to be leveled, and uses the movement of the vehicle during loading to scrape the bulk material in the car body level.
[0003] In existing technology, when a coal leveler performs coal leveling operations on the coal in the cargo compartment, excess coal on both sides of the compartment easily separates from the compartment under the push of the leveler. Excess coal in the middle falls from the end of the compartment under the push of the leveler. The leveler is not equipped with a collection device to recover the separated coal, resulting in the loss of coal resources. Furthermore, due to the uneven distribution of coal inside the compartment, some areas are missing coal after the leveling operation, reducing the amount of coal in the compartment and the amount of coal transported to the designated location. When the leveler removes excess coal from the compartment, the coal inside the leveling frame cannot move to the collection troughs on both sides on its own. As a result, the coal in the middle of the compartment easily falls off the compartment after the leveler moves to the end, causing a waste of coal resources.
[0004] To address the aforementioned technical problems, this application proposes a solution. Summary of the Invention
[0005] The purpose of this invention is to transfer excess coal to the collection box using a shaftless auger, reducing coal loss and waste during coal leveling operations. The invention then detects the amount of coal inside the cargo box and replenishes it where needed. Excess coal is collected by a second coal leveler at the rear, ensuring sufficient coal in the cargo box. During transport by conveyor belt one, scraper one pushes coal from the inside of the leveling frame into the collection troughs on both sides. This allows coal in the middle of the cargo box to be collected and replenished when insufficient coal is present. Furthermore, the movement of scraper one drives conveyor belt two, which pushes coal into the leveling frame, improving the efficiency of excess coal collection. This addresses the problem of resource waste and low efficiency caused by the inability to collect excess coal during leveling operations, and proposes an intelligent hydraulic coal leveler with an automatic control system.
[0006] The objective of this invention can be achieved through the following technical solutions:

[0014] In a preferred embodiment of the present invention, a roller is rotatably connected to the inner side of the roller frame via a rotating shaft.

[0015] In a preferred embodiment of the present invention, a drive gear is rotatably connected to the outer wall of the coal leveling frame at the position corresponding to the gear column, and a drive gear wheel is rotatably connected to the outer wall of the coal leveling frame at the position corresponding to the drive gear. A drive wheel is rotatably connected to the upper surface of the support frame via a support frame, and the drive wheel and the drive gear wheel are connected by a transmission belt. A transmission wheel is rotatably connected to the outer wall of the support frame near the drive wheel, and a transmission wheel is rotatably connected to the upper surface of the support frame near the telescopic hose via a support frame. The transmission wheel is connected to the transmission wheel through a connecting rod. A plurality of convex balls are integrally formed on the outer wall of the transmission wheel, and convex balls are also integrally formed on the lower surface of the collection box at the positions corresponding to the convex balls.
[0016] In a preferred embodiment of the present invention, mounting holes are provided on both sides of the upper surface of the coal frame. A conveyor belt is rotatably connected to the inner side wall of the coal frame at the position corresponding to the mounting holes via a conveyor roller. A plurality of evenly distributed scraper blades are installed on the outer side wall of the conveyor belt.

[0018] Compared with the prior art, the beneficial effects of the present invention are:
[0019] 1. The automatic control system enables the coal leveler to precisely stop on one side of the moving coal car's cargo compartment. The coal leveler then moves with the coal car to perform coal leveling operations and transfers excess coal to the collection box via a shaftless auger, reducing coal loss and waste during the leveling process. The coal leveler then detects the amount of coal inside the cargo compartment and replenishes the coal where it is insufficient. Any excess coal is collected by the second coal leveler at the rear, ensuring that the cargo compartment is filled with sufficient coal.
[0020] 2. During the transmission process, the conveyor belt drives the scraper to push the coal inside the coal leveling frame into the collection troughs on both sides. When the coal leveler is working, the coal in the middle of the cargo box can be collected to supplement the insufficient position. When the scraper moves, it can drive the conveyor belt to transmit and push the coal inside the coal leveling frame through the scraper. This improves the efficiency of the coal leveler in collecting excess coal and helps to improve the coal leveling efficiency. Attached Figure Description

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.
[0033] Example 1:
[0034] Please see Figure 1-4 and Figure 7-9As shown, an intelligent hydraulic coal leveler with an automatic control system includes a cargo box 1, a coal leveler 3 above the cargo box 1, hydraulic push rods 2 installed on both sides of the upper surface of the coal leveler 3, the hydraulic push rods 2 pushing the coal leveler 3 to adjust its position under the control of the automatic control system, the coal leveler 3 includes a coal leveling frame 37, a shovel plate 38 integrally formed on the lower surface of the coal leveling frame 37, the shovel plate 38 shoveling excess coal into the coal leveling frame 37 during the movement of the coal leveling frame 37, material collection troughs 34 integrally formed at both ends of the coal leveling frame 37, a conveying pipe 310 installed on the rear surface of the material collection trough 34, a material collection box 31 connected to the upper end of the material collection pipe 310 through a telescopic hose 35, a shaftless auger 33 installed inside the material collection pipe 310, and the material collection box 31. A drive motor is installed on the upper surface corresponding to the position of the shaftless auger 33. The output end of the drive motor is connected to the shaftless auger 33 and drives the shaftless auger 33 to rotate. Support frames 32 are installed on both sides of the upper surface of the coal leveling frame 37 corresponding to the positions of the conveying pipe 310. Limit rods 311 are slidably connected to the upper surface of the support frame 32 in four directions corresponding to the telescopic hose 35. A telescopic spring 39 is installed on the lower surface of the collection box 31 corresponding to the position of the limit rod 311. The telescopic spring 39 is sleeved on the outside of the limit rod 311 to support the collection box 31. Support plates 315 are installed on both sides of the outer wall of the coal leveling frame 37 near the position of the collection box 31. A connecting shaft 313 is slidably connected to the middle position of the upper surface of the support plate 315. A roller frame 312 is installed at the lower end of the 313. A mounting plate 314 is installed on the outer wall of the connecting shaft 313 near the upper part of the roller frame 312. A gear column 317 is integrally formed on the upper part of the outer wall of the connecting shaft 313. A second telescopic spring 318 is installed on the lower surface of the support plate 315 near the outer side of the connecting shaft 313. A roller is rotatably connected to the inner side of the roller frame 312 via a rotating shaft. A third drive gear is installed on the outer wall of the roller frame 312 at the position corresponding to the rotating shaft. A second transmission gear is rotatably connected on the lower surface of the mounting plate 314 at the position corresponding to the third drive gear. The second transmission gear and the third drive gear are on the same horizontal plane and interlock to drive each other to rotate. A third transmission gear is rotatably connected on the upper surface of the mounting plate 314 at the position corresponding to the second transmission gear. The third and second transmission gears are on the same horizontal plane. After the roller frame 312 is compressed and moves upward, the third transmission gear and the second transmission gear interlock and rotate. The fourth transmission gear is installed on the outer wall of the connecting shaft 313 at the position corresponding to the third transmission gear. The fourth transmission gear is perpendicular to the third transmission gear and interlocks with it, driving it to rotate. A rotating seat is installed on the outer wall of the connecting shaft 313 near the lower part of the fourth transmission gear. The connecting shaft 313 is divided into upper and lower parts by the rotating seat. The upper part of the connecting shaft 313 can rotate with the rotation of the fourth transmission gear. The first drive gear 323 is rotatably connected on the outer wall of the flat coal frame 37 at the position corresponding to the gear column 317. The first drive gear 323 and the gear column 317 interlock and drive each other to rotate.A drive gear wheel 324 is rotatably connected to the outer wall of the flat coal frame 37 at the position corresponding to the drive gear 323. The drive gear wheel 324 and the drive gear 323 are perpendicular to each other and interlock to drive each other to rotate. A drive wheel 322 is rotatably connected to the upper surface of the support frame 32 via a support frame 36. The drive wheel 322 and the drive gear wheel 324 are connected by a transmission belt 316. A transmission wheel 321 is rotatably connected to the outer wall of the support frame 36 near the top of the drive wheel 322. The drive wheel 322 and the transmission wheel 321 are connected by a transmission belt 316. A transmission wheel 325 is rotatably connected to the upper surface of the support frame 32 near the telescopic hose 35 via a support frame 319. The transmission wheel 325 is connected to the transmission wheel 321 via a connecting rod 320. Several convex balls are integrally formed on the outer wall of the transmission wheel 325. Corresponding convex balls are also integrally formed on the lower surface of the collection box 31. When the transmission wheel 325 rotates, the interaction between the convex balls on its surface and the convex balls on the lower surface of the collection box 31 causes the collection box 31 to vibrate, thus promoting a more even distribution of coal inside the collection box 31.
[0035] A coal leveler 3 with the same structure is also provided behind the coal leveler 3 connected to the lower end of the hydraulic push rod 2.
[0036] Several evenly distributed discharge pipes are installed on the lower surface of the collection box 31. Control valves are installed on the upper part of the outer wall of each discharge pipe. Flow rate sensors are installed on the outer wall of the discharge pipe near the control valves. Several evenly distributed infrared distance sensors are installed on the outer wall of the coal leveling frame 37 near the collection box 31. Infrared distance sensors are installed on the outer wall of the collection box 31 near the coal leveling frame 37.
[0037] In the prior art, when the coal leveler 3 performs coal leveling operation on the coal in the cargo compartment 1, the excess coal on both sides of the cargo compartment 1 is easily separated from the cargo compartment 1 by the coal leveler 3. The excess coal in the middle falls from the end of the cargo compartment 1 by the coal leveler 3. The coal leveler 3 is not equipped with a collection device to recover the separated coal, resulting in the loss of coal resources. In addition, due to the uneven distribution of coal inside the cargo compartment 1, some coal is missing in some places after the coal leveler 3 performs coal leveling operation, which reduces the amount of coal in the cargo compartment 1 and the amount of coal transported to the designated location.
[0038] When the coal car reaches a horizontal distance of H between itself and the leveler 3, the data reading device of the automatic control system can read the identification plate on the coal car to obtain the coal car type data G, the coal car head length data G1, the car head height data G2, the cargo box 1 height data G3, and the interval length data G4 between the car head and the cargo box 1. The data acquisition unit collects the tilt distance data C between the coal car and the infrared distance sensor 2 on the collection box 31. The tilt distance data collected for the first time is C1, and the tilt distance data detected again after time T1 is C2. The vertical distance data between the leveler 3 and the coal car's travel track is h. The travel speed data of the coal car can be calculated according to the Pythagorean theorem. The automatic control system controls the hydraulic push rod 2 to push the coal leveler 3 downward at a speed JV1 ≥ ((H-G2)F) / (H+G1). When the distance measuring device on the hydraulic push rod 2 detects that the extension distance of the hydraulic push rod 2 has reached H-G2, it stops extending. After time T2, the hydraulic push rod 2 continues to move downward at a speed JV2, where T2 = (H+G1) / F, JV2 ≥ ((G2-G3)F) / G4. When the distance measuring device on the hydraulic push rod 2 detects that the extension distance of the hydraulic push rod 2 has reached G2-G3, it stops extending. The shovel plate 38 is extended so that its lower surface fits tightly against the upper surface of the cargo box 1. Then, during the movement of the coal car, the shovel plate 38 removes and collects the excess coal in the middle of the cargo box 1. The excess coal on both sides of the cargo box 1 moves downward in a parabolic motion under the scraping action of the shovel plate 38. The falling coal can fall into the collection trough 34. The coal at the position of the shovel plate 38 also falls into the position of the collection trough 34. The coal concentrated in the collection trough 34 is transported along the transmission pipe 310 to the inside of the collection box 31 by the shaftless auger 33.
[0039] When the coal shoveling plate 38 is in close contact with the cargo box 1, the rollers in the roller frame 312 connected to the leveling frame 37 rotate by rubbing against the surface of the cargo box 1, causing the driving gear three coaxial with the inner rollers of the roller frame 312 to drive the transmission gear two to rotate. During the process of the coal shoveling plate 38 being in close contact with the cargo box 1, the rollers in the roller frame 312 first contact the surface of the cargo box 1, and then when the coal shoveling plate 38 continues to move downward, the roller frame 312 is squeezed upward, causing the squeezing deformation of the telescopic spring two 318. The transmission gear two and the transmission gear three are engaged with each other and drive to rotate, enabling the transmission gear three perpendicular to the transmission gear four to drive the upper section of the connecting shaft 313 connected to the transmission gear four to rotate. The gear column 317 connected to the upper section of the connecting shaft 313 drives the driving gear wheel 324 to rotate through the driving gear one 323 during rotation. The driving gear wheel 324 drives the driving runner 322 to rotate through the transmission belt 316. The driving runner one 321 drives the driving runner two 325 to rotate through the connecting rod 320 under the drive of the driving runner 322, causing the convex balls on the driving runner two 325 to interact with the convex balls on the bottom surface of the aggregate box 31 during rotation, making the aggregate box 31 continuously vibrate up and down, and enabling the coal material inside the aggregate box 31 to tend to be horizontally and evenly distributed under the action of the vibration force;
[0040] When the coal shoveling plate 38 removes the excess coal material on the cargo box 1, several evenly distributed infrared distance sensors one installed on one side of the leveling frame 37 can detect the vertical distance data B between the coal material inside the cargo box 1 and the infrared distance sensors one, and the time data required for the coal material to fall to the designated position If the detected data B is less than the preset falling vertical distance data K, the discharge pipe at the position corresponding to the infrared sensor one does not perform the operation of opening and replenishing materials. The falling vertical distance data K is equal to the vertical distance data between the infrared distance sensor one and the bottom surface of the coal shoveling plate 38, and the horizontal shortest distance data I between the leveling frame 37 and the discharge pipe. The time data J from the detection position to the discharge pipe position is J = I / F. If E≥J, a signal is transmitted to the control valve on the discharge pipe to keep the existing opening size of the control valve; if E<J, a signal is transmitted to the control valve on the discharge pipe to adjust the opening size of the control valve to increase. The automatic control system can obtain the shortest distance data L between the control valve opening gate on the discharge pipe and the center of the discharge pipe through the detection device, calculate the area data N of the discharge pipe opening based on the inner diameter size data M of the discharge pipe, and then calculate the discharge amount data D per second of the discharge pipe, that is, the coal material replenishment amount O at the corresponding position = ED.
[0041] Embodiment 2:
[0042] Please refer to Figure 2 and Figure 5-6As shown, mounting holes 41 are provided on both sides of the upper surface of the coal leveling frame 37. A conveyor belt 42 is rotatably connected to the inner wall of the coal leveling frame 37 via a conveyor roller 44 at the corresponding positions of the mounting holes 41. The conveyor roller 44 is connected to a drive gear wheel 324 via a coupling shaft, so that the drive gear wheel 324 can drive the conveyor belt 42 for transmission when it rotates. Several evenly distributed scraper plates 43 are installed on the outer wall of the conveyor belt 42. The scraper plates 43 are arranged at an angle on the conveyor belt 42 to facilitate scraping the coal shoveled into the inner side of the coal leveling frame 37 by the shovel plate 38 during the transmission process. A roller chamber 45 is integrally formed on one side of the lower surface of the scraper plate 43. A rolling wheel 46 is rotatably connected to the inner side of the roller chamber 45. The rolling wheel 46 rotates with the upper surface of the shovel plate 38 through friction when the scraper plate 43 moves. The drive gear 48, coaxial with the rolling wheel 46, and the transmission gear 47 are interlocked and driven to rotate. A rotating groove is provided on the outer wall of the scraper 43 at the position corresponding to the roller chamber 45. The drive gear 48 is rotatably connected to the inner side of the rotating groove through a rotating shaft. The transmission gear 47 is rotatably connected to the outer wall of the scraper 43 at the position corresponding to the drive gear 48. The outer wall of the transmission gear 47 is rotatably connected to the transmission belt 410 through the transmission roller 411. Several evenly distributed scraper 49s are installed on the outer wall of the transmission belt 410. A planetary gear structure is provided at the connection position between the transmission roller 411 and the transmission gear 47. The transmission roller 411 rotates in opposite directions with the transmission gear 47 on the same axis through the planetary gear structure, so that the scraper 49 on the transmission belt 410 can further gather the coal on the shovel plate 38 inward.
[0043] In the prior art, when the coal leveler 3 removes excess coal from the cargo box 1, the coal that has entered the inner side of the coal leveling frame 37 cannot move to the collection troughs 34 on both sides on its own. This causes the coal in the middle of the cargo box 1 to fall off the cargo box 1 after the coal leveler 3 moves to the end of the cargo box 1, resulting in a waste of coal resources.
[0044] During rotation, gear column 317 drives transmission roller 44 to rotate via drive gear 323. This causes scraper plate 43 connected to transmission roller 44 to push the coal material entering the coal leveling frame 37 to both sides during transmission. Excess coal material can move into the collection troughs 34 on both sides under the push of scraper plate 43. During the movement of scraper plate 43, rolling wheel 46 in roller chamber 45 rotates under the action of friction, causing drive gear 48, which is coaxial with rolling wheel 46, to rotate. During rotation, the transmission gear 47 can be driven to rotate. The transmission roller 411 can rotate in opposite directions with the transmission gear 47 through a planetary gear structure. This allows the transmission belt 410 driven by the transmission roller 411 to push the coal material towards the inside of the leveling frame 37 during the transmission process. As the coal material moves to both sides under the action of the scraper 43, it also moves towards the inside of the leveling frame 37 under the action of the scraper 49. It will not fall to the outside of the leveling frame 37 when moving to both sides, thus affecting the leveling effect.
[0045] In use, when the coal car reaches a horizontal distance of H between itself and the leveler 3, the data reading device of the automatic control system can read the identification plate on the coal car to obtain the coal car type data G, the coal car head length data G1, the car head height data G2, the cargo box 1 height data G3, and the interval length data G4 between the car head and the cargo box 1. The data acquisition unit collects the tilt distance data C between the coal car and the infrared distance sensor 2 on the collection box 31. The tilt distance data collected for the first time is C1, and the tilt distance data detected again after time T1 is C2. The vertical distance data between the leveler 3 and the coal car's travel track is h. The travel speed data of the coal car can be calculated according to the Pythagorean theorem. The automatic control system controls the hydraulic push rod 2 to push the coal leveler 3 downward at a speed JV1 ≥ ((H-G2)F) / (H+G1). When the distance measuring device on the hydraulic push rod 2 detects that the extension distance of the hydraulic push rod 2 has reached H-G2, it stops extending. After time T2, the hydraulic push rod 2 continues to move downward at a speed JV2, where T2 = (H+G1) / F, JV2 ≥ ((G2-G3)F) / G4. When the distance measuring device on the hydraulic push rod 2 detects that the extension distance of the hydraulic push rod 2 has reached G2-G3, it stops extending. The shovel plate 38 is extended so that its lower surface fits tightly against the upper surface of the cargo box 1. Then, during the movement of the coal car, the shovel plate 38 removes and collects the excess coal in the middle of the cargo box 1. The excess coal on both sides of the cargo box 1 moves downward in a parabolic motion under the scraping action of the shovel plate 38. The falling coal can fall into the collection trough 34. The coal at the position of the shovel plate 38 also falls into the position of the collection trough 34. The coal concentrated in the collection trough 34 is transported along the transmission pipe 310 to the inside of the collection box 31 by the shaftless auger 33.
[0046] When the coal shoveling plate 38 is in close contact with the cargo box 1, the rollers in the roller frame 312 connected to the leveling frame 37 rub against the surface of the cargo box 1 to drive the rollers to rotate, causing the drive gear three coaxial with the inner rollers of the roller frame 312 to drive the transmission gear two to rotate. During the process of the coal shoveling plate 38 being in close contact with the cargo box 1, the rollers in the roller frame 312 first contact the surface of the cargo box 1, and then when the coal shoveling plate 38 continues to move downward, the roller frame 312 is squeezed upward, causing the compression deformation of the telescopic spring two 318. The transmission gear two and the transmission gear three are engaged with each other and drive each other to rotate, enabling the transmission gear three perpendicular to the transmission gear four to drive the upper section of the connecting shaft 313 connected to the transmission gear four to rotate. The gear column 317 connected to the upper section of the connecting shaft 313 drives the drive gear wheel 324 to rotate through the drive gear one 323 during rotation. The drive gear wheel 324 drives the drive wheel 322 to rotate through the transmission belt 316. The drive wheel one 321 drives the drive wheel two 325 to rotate through the connecting rod 320 under the drive of the drive wheel 322, causing the convex balls on the drive wheel two 325 to interact with the convex balls on the bottom surface of the aggregate box 31 during rotation, making the aggregate box 31 continuously vibrate up and down, and enabling the coal material inside the aggregate box 31 to tend to be horizontally and evenly distributed under the action of the vibration force;
[0047] When the coal shoveling plate 38 removes the excess coal material on the cargo box 1, several evenly distributed infrared distance sensors one installed on one side of the leveling frame 37 can detect the vertical distance data B between the coal material inside the cargo box 1 and the infrared distance sensors one, and the time data required for the coal material to fall to the designated position If the detected data B is less than the preset falling vertical distance data K, the discharge pipe at the position of the corresponding infrared sensor one does not perform the operation of opening and replenishing materials. The falling vertical distance data K is equal to the vertical distance data between the infrared distance sensor one and the bottom surface of the coal shoveling plate 38, and the horizontal shortest distance data I between the leveling frame 37 and the discharge pipe. The time data J from the detection position to the discharge pipe position is J = I / F. If E≥J, a signal is transmitted to the control valve on the discharge pipe to continue maintaining the existing opening size of the control valve; if E<J, a signal is transmitted to the control valve on the discharge pipe to adjust the opening size of the control valve to increase;
[0048] During rotation, gear column 317 drives transmission roller 44 to rotate via drive gear 323. This causes scraper plate 43 connected to transmission roller 44 to push the coal material entering the coal leveling frame 37 to both sides during transmission. Excess coal material can move into the collection troughs 34 on both sides under the push of scraper plate 43. During the movement of scraper plate 43, rolling wheel 46 in roller chamber 45 rotates under the action of friction, causing drive gear 48, which is coaxial with rolling wheel 46, to rotate. During rotation, the transmission gear 47 can be driven to rotate. The transmission roller 411 can rotate in opposite directions with the transmission gear 47 through a planetary gear structure. This allows the transmission belt 410 driven by the transmission roller 411 to push the coal material towards the inside of the leveling frame 37 during the transmission process. As the coal material moves to both sides under the action of the scraper 43, it also moves towards the inside of the leveling frame 37 under the action of the scraper 49. It will not fall to the outside of the leveling frame 37 when moving to both sides, thus affecting the leveling effect.
