Description

Technical Field

[0001] The invention belongs to the technical field of mining equipment, in particular to a coal crushing device used for coal mining. Background Art

[0002] As a key fossil energy source, coal occupies a crucial position in the global energy mix. It is widely used in numerous industries, including electricity, steel, and chemicals, providing essential energy for industrial production and daily life. However, due to the varying depths at which coal resources are buried, they are typically mined through both underground and open-pit mining. Only 7.5% of my country's reserves are mineable, primarily through underground mining.

[0003] A coal-mining equipment with publication number CN113833460B further crushes the coal inside the mine to achieve transportation through a crushing device installed in the shovel plate. However, when the crushing head of the equipment is working, it rotates centrifugally at high speed, so it will knock away the ore it contacts, making it difficult for the ore to fall into the shovel plate below, resulting in a large amount of ore accumulating inside the mine, reducing the ore collected by the device, so improvement is needed. Summary of the Invention

[0004] Aiming at the problem that the crushing head of the prior art easily throws away the ore when rotating at high speed, the technical solution adopted by the present invention is: a coal mine crushing equipment for coal mining, comprising: Excavation components, used to break up the coal from the inner walls of the mine; Transfer unit, used to collect coal crushed by the tunneling unit; The transmission component is arranged inside the transfer component and is used to transport the coal to the rear; The excavation component comprises: An oblique supporting shell, wherein a pressurizing component is provided at the bottom of the oblique supporting shell, and a moving component is provided at the bottom of the pressurizing component; A propulsion inner plate, the outer surface of which is slidably connected to the inner wall of the oblique support shell via meshing rollers, and a rotation joint is provided at the top end of the propulsion inner plate; The screwing unit has a bottom that is fixedly connected to the outer surface of the oblique support shell, and a rotating shaft at the top of the screwing unit that is plugged into the axis of the rotating joint. The screwing unit is composed of a connecting plate on the side and a screwing motor on the top. The connecting plate can extend and lengthen as the inner plate moves in a directional manner to ensure that the screwing motor is always located on the side of the rotating joint. The rotating housing has a torque motor installed in its inner cavity. The axis of the rotating housing is connected to the top of the inner plate through a rotating joint. When the screwing unit controls the rotating joint to rotate, the rotating housing is driven to rotate. Crushing drum, the axis of which is plugged into the outer surface of the torque motor shaft. The outer surface of the crushing drum has metal spikes, which can crush the mineral materials it touches when it rotates; The receiving component is arranged outside the crushing drum and is used to collect the crushed coal. The inner wall of the receiving component does not contact the crushing drum and a large enough space is reserved for collecting the ore. The guiding component is used to transport the coal from top to bottom out of the storage component.

[0005] Furthermore, the guide component includes: A guide tube shell, the guide tube shell being plugged into the bottom of the inner cavity of the receiving component; A sliding inner tube, wherein the outer surface of the sliding inner tube is slidably connected to the inner wall of the guide tube shell, the top end of the sliding inner tube is fixedly connected to an elastic sleeve, and the top end of the elastic sleeve is fixedly connected to the top of the inner wall of the guide tube shell; A fixed base, a connecting hose is fixedly connected to the axis of the upper surface of the fixed base, and the top of the connecting hose is fixedly connected to the bottom end of the sliding inner tube. Since the bottom of the sliding inner tube is connected to the connecting hose that can be bent and deformed, the guide tube shell can drive the sliding inner tube to perform a certain degree of lateral movement, thereby synchronously rotating the box shell.

[0006] Furthermore, the pressurizing component includes: A transfer box, wherein the top of the inner cavity of the transfer box is symmetrically provided with exhaust grooves, and the bottom of the transfer box is fixedly connected to the upper surface of the moving component; A flow diverter, wherein the outer surface of the flow diverter is sleeved with the inner wall of the transfer box, and the top of the inner wall of the flow diverter is evenly provided with through suction ports, and the through suction ports extend to the outside of the transfer box; A control switch, the outer surface of the control switch is fixedly connected to the outer surface of the transfer box, the top of the inner cavity of the control switch is connected to a guide shaft through a rotating motor, and the outer surface of the guide shaft is provided with a closed baffle. The control switch can drive the closed baffle to rotate by rotating the guide shaft, so that the closed baffle fits the opening of the transfer box. At this time, the opening on the left side of the transfer box will fit with the transport belt, so that the deflector will inhale air through the opening on the right side of the transfer box, and pressurize the transfer component on the right. At this time, because there is no reserved space on the upper part of the transport belt, the transport belt cannot continue to transport the coal to the left side of the device, and the material transportation work is temporarily stopped.

[0007] Furthermore, the transfer component includes: A transport belt, wherein a middle portion of an outer surface of the transport belt is slidably connected to an inner wall of the transfer box; A filling inner plate, wherein the outer surface of the filling inner plate is slidably connected to the inner wall of the transport belt, and both ends of the filling inner plate are rotatably connected to the transmission roller; The transmission motor has an outer surface of an output shaft of the transmission motor plugged into the inner cavity of the transmission roller shaft, an outer surface of the left transmission motor is fixedly connected to the left side of the outer surface of the moving component, and the right transmission motor is arranged inside the transfer component.

[0008] Furthermore, the transfer component includes: An extended bottom shell, wherein the outer surface of the extended bottom shell is fixedly connected to the outer surface of the transfer box, and the top of the inner cavity of the extended bottom shell is plugged into the outer surface of the fixed base through a docking groove; Side guide rails are provided on the inner wall of the extended bottom shell. The outer surface of the transport belt is slidably connected to the inner wall of the extended bottom shell through the side guide rails. The side guide rails are used to guide the transport belt to rotate and tighten the transport belt to prevent the transport belt from being squeezed and deformed by the coal. The metal parts are removed. The metal parts are arranged on the side of the inner wall of the extended bottom shell away from the transfer box. The lower part of the outer surface of the metal parts is pressed against the outer surface of the transport belt. A discharge chute is provided at the bottom of the inner cavity of the extended bottom shell. The transport belt rotates counterclockwise on the way. When it returns to the position where the metal parts are removed, it will rub against the bottom of the metal parts, thereby cleaning the coal slag attached to the outer surface of the transport belt through the discharge chute at the bottom. A built-in monitor is provided in the inner cavity of the extended bottom shell, and the lens of the built-in monitor extends to a side close to the transport belt. The built-in monitor observes the coal transported above the transport belt and transmits the image to a display screen outside the cave.

[0009] Furthermore, the storage component includes: The material holding shell has through-holes evenly formed on the bottom of the inner cavity of the material holding shell, and the top of the outer surface of the guide tube shell is plugged into the bottom of the inner cavity of the material holding shell through the through-holes; A pressure plate, the bottom of which is plugged into the top of the inner cavity of the material holding shell, and the top of which extends to the outside of the material holding shell; An oblique slide plate, the outer surface of which is slidably connected to the lower part of the inner cavity of the material holding shell, and a return spring belt is fixedly connected to the inner wall of the oblique slide plate, the bottom end of which is fixedly connected to the inner cavity of the material holding shell. When the oblique slide plate completely slides out from the interior of the material holding shell, it will not contact the conical teeth on the outer surface of the crushing drum, but will narrow the gap between the crushing drum and the material holding shell, thereby reducing the amount of coal entering the guiding component below. The filling swivel is used to fill the gap between the material shell and the crushing drum, so that the crushing drum can rotate stably.

[0010] Furthermore, the filling swivel includes: A sleeve ring shell, wherein the outer surface of the sleeve ring shell is fixedly connected to the axis of the inner wall of the material holding shell, and the axis of the inner wall of the sleeve ring shell is rotatably connected to the outer surface of the torque motor shaft; A sliding rod shell, the top end of which extends to the outside of the sleeve ring shell through a sliding opening, and the front end of the sliding rod shell is pressed against the outer surface of the crushing drum, and a counterweight striker is sleeved on the inner wall of the sliding rod shell; The outer surface of the sliding rod shell is sleeved with a spring sleeve, and the inner wall of the material holding shell is evenly provided with docking holes on the side close to the sleeve ring shell. The end of the counterweight impact rod away from the sliding rod shell is squeezed against the inner wall of the material holding shell through the docking hole. When the crushing drum rotates, the docking protrusions on the flat parts on both sides of it will continuously contact and squeeze with the circular surface of the sliding rod shell, and then separate from the sliding rod shell. Therefore, the sliding rod shell will drive the counterweight impact rod to continuously hit the docking hole of the sleeve ring shell, causing the material holding shell to vibrate at high frequency as a whole.

[0011] The beneficial effects of the present invention are as follows: 1. The device crushes the mineral materials it contacts through the high-speed rotating crushing drum. At this time, part of the crushed mineral materials falls into the inside of the receiving component under the action of their own gravity, and the other part of the mineral materials will adhere to the outer surface of the crushing drum. As the crushing drum rotates, it will be centrifugally thrown sideways, and then it will contact the inner wall of the receiving component and gather inside the receiving component, thereby greatly increasing the collected mineral materials and avoiding the problem of too little mineral materials being collected due to the centrifugal rotation of the crushing drum. The receiving component is sleeved on the outside of the crushing drum, and the shaft rings filled on both sides of the crushing drum axis can make the crushing drum rotate more stably, reduce the load on the rotating shaft of the rotating box shell, and extend the service life of the device.

[0012] 2. The excavation component can propel and deflect the receiving component, thereby controlling the movement of the crushing drum, so that the crushing drum can adjust its position according to the actual situation inside the mine, ensuring that the crushing drum can carry out mining work and avoiding the problem of idling of the crushing drum. After the relevant pipe body of the guide component is modified, it is ensured that the pipe body has the function of guiding coal. The sliding inner tube can be offset and slided to a certain extent with the receiving component, avoiding the problem of the sliding inner tube breaking due to pulling.

[0013] 3. The pressurizing component can give the receiving component a certain degree of adsorption capacity, so that the crushed fine coal can enter the interior of the receiving component through adsorption and guidance, reducing the coal particles diffused inside the mine, thereby avoiding the problem of smoke and dust explosion. The through-suction port maintains a certain distance from the upper surface of the transport belt, so the coal on the upper surface of the transport belt will not block the through-suction port due to adsorption, thereby enabling the drain to perform suction and pressurization work inside the mine for a long time.

[0014] 4. When the amount of coal collected exceeds the actual transfer capacity of the transport belt, in order to prevent the coal from blocking the transport passage of the transport belt, the amount of ore entering the guide component can be reduced by adjusting the distance between the inclined slide and the crushing drum. Without changing the speed of the crushing drum, the transfer amount of coal on the upper surface of the transport belt is limited, so that the crushing drum can rotate at a constant speed. The torque motor rotating at a constant speed does not need to be adjusted and controlled, avoiding the problem that the crushing drum frequently adjusts its speed due to changes in the amount of coal collected, which makes the torque motor easily damaged due to high-frequency adjustment work.

[0015] 5. During the high-speed rotation of the crushing drum, the circular surface on the side of the crushing drum will continuously push the sliding rod shell that is sleeved with the raised ring shell, and the counterweight impact rod sleeved with the sliding rod shell will continuously hit the inner wall of the material containing shell. Then the material containing shell will continuously vibrate, so that the coal accumulated on the inner wall of the material containing shell can be loosened by shaking, and the coal can pass through the through-hole at the bottom more easily. To a certain extent, it can avoid the problem of coal accumulating at the bottom of the inner wall of the material containing shell and clogging the through-hole. BRIEF DESCRIPTION OF THE DRAWINGS

[0018] The present invention will be described in further detail below with reference to the accompanying drawings and specific embodiments. The embodiments of the present invention are provided for purposes of illustration and description and are not intended to be exhaustive or to limit the invention to the disclosed forms. Many modifications and variations will be apparent to those skilled in the art. The embodiments are chosen and described to better illustrate the principles of the invention and its practical application, and to enable those skilled in the art to understand the invention and design various embodiments with various modifications suitable for specific applications.

[0019] Example 1, please refer to Figure 1-Figure 5 The present invention provides a technical solution: a coal crushing device for coal mining, comprising: Excavation component 1, used to break up the coal on the inner wall of the mine; The transfer component 2 is used to collect the coal crushed by the excavation component 1; The transmission component 3 is arranged inside the transfer component 2 and is used to transport the coal to the rear; The excavation component 1 comprises: An oblique support shell 11 is provided with a pressurizing component 4 at the bottom of the oblique support shell 11, and a moving component 5 is provided at the bottom of the pressurizing component 4; The outer surface of the pushing inner plate 12 is slidably connected to the inner wall of the oblique support shell 11 through meshing rollers, and a rotating joint 14 is provided at the top of the pushing inner plate 12; The screwing unit 13 has its bottom fixedly connected to the outer surface of the oblique support shell 11, and its top shaft is plugged into the axis of the rotary joint 14. The screwing unit 13 is composed of a connecting plate on the side and a screwing motor on the top. The connecting plate can extend and lengthen as the inner plate 12 moves in a directional sliding manner, ensuring that the screwing motor is always located on the side of the rotary joint 14. The rotating housing 15 has a torque motor installed in its inner cavity. The axis of the rotating housing 15 is connected to the top of the pushing inner plate 12 through a rotating joint 14. When the screwing unit 13 controls the rotating joint 14 to twist, the rotating housing 15 is driven to rotate. Crushing drum 16, the axis of the crushing drum 16 is plugged into the outer surface of the torque motor shaft. The outer surface of the crushing drum 16 has metal spikes, which can crush the mineral materials it touches when it rotates; The receiving component 6 is arranged outside the crushing drum 16 and is used to collect the crushed coal. The inner wall of the receiving component 6 does not contact the crushing drum 16 and a large enough space is reserved for collecting the ore. The guiding component 7 is used to transport the coal from the top to the bottom of the storage component 6.

[0020] The guide component 7 includes, The guide tube shell 71 is plugged into the bottom of the inner cavity of the receiving component 6; The sliding inner tube 73 has an outer surface that is slidably connected to the inner wall of the guide tube shell 71 , and the top of the sliding inner tube 73 is fixedly connected to the elastic sleeve 72 , and the top of the elastic sleeve 72 is fixedly connected to the top of the inner wall of the guide tube shell 71 ; A fixed base 74 is provided, and a connecting hose 75 is fixedly connected to the axis of the upper surface of the fixed base 74, and the top end of the connecting hose 75 is fixedly connected to the bottom end of the sliding inner tube 73. Since the bottom end of the sliding inner tube 73 is connected to the connecting hose 75 that can be bent and deformed, the guide tube shell 71 can drive the sliding inner tube 73 to perform a certain degree of lateral movement, thereby synchronously rotating the box shell 15.

[0021] The pressurizing component 4 includes: Transfer box 41, the top of the inner cavity of transfer box 41 is symmetrically provided with exhaust grooves 43, and the bottom of transfer box 41 is fixedly connected to the upper surface of moving part 5; The flow guider 42 has an outer surface that is sleeved with the inner wall of the transfer box 41 , and a through suction port 44 is evenly provided on the top of the inner wall of the flow guider 42 , and the through suction port 44 extends to the outside of the transfer box 41 ; Control switch 45, the outer surface of the control switch 45 is fixedly connected to the outer surface of the transfer box 41, and the top of the inner cavity of the control switch 45 is connected to the guide shaft 46 through a rotating motor. The outer surface of the guide shaft 46 is provided with a closed baffle 47. The control switch 45 can drive the closed baffle 47 to rotate by rotating the guide shaft 46, so that the closed baffle 47 fits the opening of the transfer box 41. At this time, the opening on the left side of the transfer box 41 will fit the transport belt 31, so that the deflector 42 draws air through the opening on the right side of the transfer box 41, and pressurizes the transfer component 2 on the right side. At this time, because there is no reserved space on the upper part of the transport belt 31, the transport belt 31 cannot continue to transport the coal to the left side of the device, and the material transportation work is temporarily stopped.

[0022] The transfer unit 2 includes: The transport belt 31 has a middle portion of an outer surface thereof slidably connected to an inner wall of the transfer box 41; The filling inner plate 33 has an outer surface that is slidably connected to the inner wall of the transport belt 31, and both ends of the filling inner plate 33 are rotatably connected to transmission rollers; The transmission motor 32, the outer surface of the output shaft of the transmission motor 32 is plugged into the inner cavity of the transmission roller shaft, the outer surface of the left transmission motor 32 is fixedly connected to the left side of the outer surface of the moving part 5, and the right transmission motor 32 is arranged inside the transfer part 2.

[0023] When the device is used for operation, the device is automatically driven into the mine through the movable part 5 at the bottom. Figure 1 For example, relevant transport equipment is connected to the left side of the transmission component 3 to transport the ore out of the mine.

[0024] When the moving part 5 advances into the interior of the mine, the excavation part 1 crushes the mineral material that comes into contact with the inner wall of the mine by twisting the crushing roller 16. The crushed mineral material then enters the interior of the storage part 6 and is transferred to the area on the right side of the upper surface of the transport belt 31 through the guide part 7. Since the transmission motor 32 controls the transport belt 31 to rotate counterclockwise, the mineral material will be transported to the left through the transport belt 31. Through the connected transfer equipment, the mineral material is continuously mined out from the interior of the mine.

[0025] Since the environment inside the mine is relatively complex, in order to enable the device to perform more reliable automated operation, the excavation component 1 also needs to be continuously adjusted by the external remote control component through the matching monitoring component. The meshing rollers inside the oblique support shell 11 push the inner plate 12 outward by actively rolling, and then the screwing units 13 on both sides can control the deflection of the rotating box shell 15 by screwing the rotating joint 14 to ensure that the crushing drum 16 can fully contact the inner wall of the mine, so as to perform the mineral crushing action normally. On the one hand, the crushed mineral will fall into the interior of the storage component 6 under the action of its own gravity. On the other hand, in the process of the crushing drum 16 throwing the contacted mineral to the side, the flying mineral will contact the inner wall of the storage component 6, and then fall along the inner wall of the storage component 6 and will also be collected inside the storage component 6.

[0026] When the mineral material slides down to the bottom area along the storage component 6, it will be guided along the tube body composed of the guide tube shell 71 and the sliding inner tube 73 to slide to the upper surface of the transport belt 31. As the rotating box shell 15 drives the storage component 6 to move and deflect, the sliding inner tube 73 will also perform corresponding sliding movement along the inner wall of the guide tube shell 71. The fixed base 74 can ensure that the sliding inner tube 73 is always connected to the transfer component 2, and the connecting hose 75 can enable the sliding inner tube 73 to bend and deform to a certain extent as the storage component 6 deflects.

[0027] The crushed ore needs to be guided into the interior of the storage component 6, so a pressure component 4 is set in the middle. When the control switch 45 on the left side of the pressure component 4 closes the closed baffle 47 by rotating the guide shaft 46, the opening on the left side of the transfer box 41 will be greatly reduced. At this time, when the deflector 42 performs a vacuum operation on the interior of the transfer box 41 through the through suction port 44, since the transfer box 41 is connected to the transfer component 2 on the right, and the transfer component 2 is connected to the storage component 6 through the guide component 7, the storage component 6 has adsorption capacity, and the crushed fine coal can enter the interior of the storage component 6 by adsorption guidance, but the through suction port 44 maintains a certain distance from the upper surface of the transport belt 31, so the coal on the upper surface of the transport belt 31 will not block the through suction port 44 due to adsorption. When the coal on the upper part of the transport belt 31 needs to be transported out of the mine, the closed baffle 47 is opened again to enable the transport belt 31 to perform the transfer work.

[0028] Example 2, please refer to Figures 1-8 The present invention provides a technical solution: based on embodiment 1, the transfer component 2 includes: The extended bottom shell 21, the outer surface of the extended bottom shell 21 is fixedly connected to the outer surface of the transfer box 41, and the top of the inner cavity of the extended bottom shell 21 is plugged into the outer surface of the fixed base 74 through the docking groove; The side guide rails 22 are provided on the inner wall of the extended bottom shell 21. The outer surface of the transport belt 31 is slidably connected to the inner wall of the extended bottom shell 21 through the side guide rails 22. The side guide rails 22 are used to guide the transport belt 31 to rotate and tighten the transport belt 31 to prevent the transport belt 31 from being squeezed and deformed by the coal. The metal piece 23 is removed. The metal piece 23 is arranged on the side of the inner wall of the extended bottom shell 21 away from the transfer box 41. The lower part of the outer surface of the metal piece 23 is pressed against the outer surface of the transport belt 31. A discharge chute 24 is provided at the bottom of the inner cavity of the extended bottom shell 21. The transport belt 31 rotates counterclockwise on the way. When it returns to the position where the metal piece 23 is located, it will rub against the bottom of the metal piece 23, thereby cleaning the coal slag attached to the outer surface of the transport belt 31 through the discharge chute 24 at the bottom. The built-in monitor 25 is arranged in the inner cavity of the extended bottom shell 21, and the lens of the built-in monitor 25 extends to the side close to the transport belt 31. The built-in monitor 25 observes the coal transported above the transport belt 31 and transmits the image to the display screen outside the cave.

[0029] The storage component 6 includes: The material holding shell 61 has through-holes 62 evenly formed at the bottom of the inner cavity of the material holding shell 61, and the top of the outer surface of the guide tube shell 71 is plugged into the bottom of the inner cavity of the material holding shell 61 through the through-holes 62; A pressure plate 63, the bottom of which is plugged into the top of the inner cavity of the material holding shell 61, and the top of which extends to the outside of the material holding shell 61; The oblique slide 64 has an outer surface that is slidably connected to the lower portion of the inner cavity of the material holding shell 61, and a return spring belt 65 is fixedly connected to the inner wall of the oblique slide 64. The bottom end of the return spring belt 65 is fixedly connected to the inner cavity of the material holding shell 61. When the oblique slide 64 completely slides out from the interior of the material holding shell 61, it will not contact the conical teeth on the outer surface of the crushing drum 16. However, it will reduce the gap between the crushing drum 16 and the material holding shell 61, thereby reducing the amount of coal entering the guide component 7 below. The filling swivel 8 is used to fill the gap between the material holding shell 61 and the crushing drum 16, so that the crushing drum 16 can rotate stably.

[0030] The filling swivel 8 comprises, The outer surface of the sleeve ring shell 82 is fixedly connected to the axis of the inner wall of the material holding shell 61, and the axis of the inner wall of the sleeve ring shell 82 is rotatably connected to the outer surface of the torque motor shaft; The sliding rod shell 83 has its top end extended to the outside of the sleeve ring shell 82 through the sliding opening, and the front end of the sliding rod shell 83 is pressed against the outer surface of the crushing drum 16, and the inner wall of the sliding rod shell 83 is sleeved with a counterweight striker 84; The outer surface of the sliding rod shell 83 is sleeved with a spring sleeve, and the inner wall of the material holding shell 61 close to the sleeve ring shell 82 is evenly provided with docking holes 81. The end of the counterweight striker 84 away from the sliding rod shell 83 is squeezed against the inner wall of the material holding shell 61 through the docking hole 81. When the crushing drum 16 rotates, the docking protrusions on the flat parts on both sides of it will continuously contact and squeeze with the circular surface of the sliding rod shell 83, and then separate from the sliding rod shell 83. Therefore, the sliding rod shell 83 will drive the counterweight striker 84 to continuously hit the docking hole 81 of the sleeve ring shell 82, causing the material holding shell 61 to vibrate at high frequency as a whole.

[0031] Since the fixed base 74 is connected to the slot of the extended bottom shell 21, the coal dropped from the fixed base 74 will fall to the right side of the transport belt 31 and be transported from right to left by the transport belt 31. The two sides of the transport belt 31 are restricted in the side guide rails 22, and the interior of the transport belt 31 is provided with a filling inner plate 33, so the transport belt 31 can bear a certain degree of coal without collapse and deformation, thereby realizing the normal work of transporting coal. The height of the coal transported on the upper surface of the transport belt 31 is observed by the built-in monitor 25 on the side to obtain the transportation flow of the coal and judge whether it is necessary to increase or decrease the mining speed of the coal. When the rotating transport belt 31 passes through the area where the removal metal part 23 is located, the sharp surface of the removal metal part 23 will rub against the outer surface of the transport belt 31, thereby removing the coal slag adhered to the outer surface of the transport belt 31 and discharging it through the discharge trough 24 at the bottom, preventing the coal from adhering to the outer surface of the transport belt 31 for a long time.

[0032] The structure of the material holding shell 61 is as follows: Figure 7As shown, since the bottom of the material holding shell 61 is an arc-shaped structure, the coal falling into the material holding shell 61 usually enters the guide tube shell 71 from the through-hole 62 due to the effect of gravity to realize the transfer work. When the amount of coal collected is too much and exceeds the actual transfer capacity of the transport belt 31, in order to prevent the coal from blocking the transport passage of the transport belt 31, the pressure plates 63 on both sides will pressurize the inner cavity of the material holding shell 61 to push the oblique slides 64 on both sides obliquely upward. At this time, it is difficult for the coal to pass through the crushing drum 16 and the oblique slides. The gap of the slide 64 is increased, so the coal falling downward through the through-hole 62 will be further reduced. Therefore, while ensuring that the rotation speed of the crushing drum 16 remains unchanged, the amount of coal entering the transfer component 2 is reduced, and the transfer load of the transport belt 31 is reduced. When the transport belt 31 transports less coal, the inclined slide 64 is retracted to the inside of the material holding shell 61, increasing the gap between the crushing drum 16 and the inclined slide 64, and the coal entering the through-hole 62 will be further increased, thereby increasing the coal flow rate transported by the transport belt 31.

[0033] During the high-speed rotation of the crushing drum 16, the circular surface on the side of the crushing drum 16 will continuously push the sliding rod shell 83 that is raised by the sleeve ring shell 82, and the counterweight impact rod 84 that is sleeved by the sliding rod shell 83 will continuously hit the inner wall of the material holding shell 61. Then the material holding shell 61 will continuously vibrate, so that the coal accumulated on the inner wall of the material holding shell 61 can be loosened by shaking, and the coal can more easily pass through the through socket 62 at the bottom. To a certain extent, it can avoid the problem of coal accumulating at the bottom of the inner wall of the material holding shell 61 and clogging the through socket 62.

[0034] Obviously, the embodiments described are only some of the embodiments of the present invention, not all of them. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field and related fields without making creative efforts should fall within the scope of protection of the present invention. Structures, devices, and operating methods not specifically described and explained in the present invention shall be implemented in accordance with conventional means in the field unless otherwise specified or limited.
