Description

Technical Field

[0001] The invention relates to a novel stone coal crusher, belonging to the technical field of coal processing equipment. Background Art

[0002] Pebble coal is a coarse-grained waste residue produced during the combustion process of coal-fired power plant boilers. It is mainly composed of unburned coal particles, ash, and a small amount of metal impurities. Due to its large particle size and high hardness, pebble coal needs to be crushed to break large pieces of pebble coal into fine particles, which can facilitate subsequent transportation, secondary combustion, and other operations. At the same time, crushing large pieces of pebble coal into fine particles can also reduce the blockage of the slag discharge system and the wear of the equipment. At present, most of the pebble coal crushers in the existing technology directly use crushing rollers to crush larger coal blocks, without performing corresponding pretreatment on the larger coal blocks, which can easily shorten the service life of the crushing rollers and increase maintenance costs.

[0003] To this end, in the prior art, there is a utility model patent with Chinese patent application number CN202121330248.6, which discloses a coal crusher for coal mining. By setting up multiple cutting discs, it can cut larger coal blocks until the volume becomes smaller and then crush them through crushing rollers, thereby extending the service life of the crushing rollers.

[0004] However, in actual use, the following problems still exist: the existing coal crushing process mostly involves first using a forklift to move the coal from the coal pile into the upper hopper, then using a belt conveyor to transport the coal from the upper hopper to the top of the crusher feed port, allowing the coal to fall into the crusher for crushing and decomposition. The above device does not have a corresponding buffer structure, which means that the coal will fall directly into the crusher, which may cause the coal to collide with the internal crushing components and splash outside the crusher. In addition, the coal feeding speed cannot be controlled, which makes it very easy for the coal to be overloaded and piled up, affecting the coal crushing efficiency. Summary of the Invention

[0005] The object of the present invention is to provide a new type of pebble coal crusher, which provides a feeding frame and a guide roller, adopts a baffle plate inside the feeding frame to carry the pebble coal, and allows the baffle plate to flip and tilt under the action of the gravity of the pebble coal material, so that the pebble coal material can slide along the upper end face of the inclined baffle plate into the feeding channel, thereby realizing the feeding and shielding of the pebble coal, and preventing the pebble coal from directly falling into the crusher and colliding with the crushing component and splashing to the outside of the crusher. At the same time, the pebble coal in the feeding channel is guided by the guide roller, and the feeding speed and quantity of the pebble coal can be controlled to avoid the situation where the pebble coal material is stuck on the crushing component due to excessive accumulation of the crushing component, thereby improving the crushing efficiency and effect, and solving the problems existing in the above-mentioned background technology.

[0016] The present invention has the following beneficial effects: The present invention provides a material conveying device for conveying the coal into the feed frame, wherein the coal is conveyed into the feed frame by the belt conveyor and the coal is conveyed into the feed frame by the belt conveyor. The coal is conveyed into the feed frame by the belt conveyor and the coal is conveyed into the feed frame by the belt conveyor. The coal is conveyed into the feed channel by the belt conveyor under the action of its own gravity, the coal is accumulated on the coal baffle plate, and the coal is guided by the coal baffle plate to slide into the feed channel, thereby preventing the coal from directly falling into the crusher and colliding with the crushing assembly and splashing to the outside of the crusher. At the same time, the coal from the coal entering the feed channel falls into the clamping groove between the two support plates on the guide roller, and the guide roller is driven by the motor to rotate, so that the coal in the clamping groove can fall into the crusher body, thereby controlling the feeding speed and amount of the coal.

[0017] 2. The present invention arranges an elastic buffer rod between the material baffle plate and the cavity.

This can be done by pressing the material baffle plate to make it flip and tilt in the cavity, thereby expanding the feeding channel, so that the stones and coal materials stuck in the feeding channel can pass through the feeding channel. In this process, the elastic buffer rod is forced to contract and generate a reset force. After the feeding channel is unblocked, the weight of the stones and coal materials on the material baffle plate becomes lighter. At this time, the elastic buffer rod can make the material baffle plate rebound to restore the feeding channel to its initial state, thereby avoiding the situation where the stone and coal materials are discharged too quickly due to the excessive diameter of the feeding channel, so as to ensure that the crushing assembly is not prone to jams, and has the advantage of ensuring the efficiency and effect of stone and coal material crushing.

In addition, the term "including" and any variations thereof are intended to cover non-exclusive inclusions.

[0021] Example 1: Please refer to Figures 1 to 5 This embodiment provides a new type of pebble coal crusher, comprising an upper hopper 1 and a crusher body 2. A belt conveyor 3 is arranged at an angle between the upper hopper 1 and the crusher body 2. The loading end of the belt conveyor 3 is arranged at the discharge port of the upper hopper 1 for receiving the pebble coal, and the lower end of the belt conveyor 3 is arranged at the feed port 10 of the crusher body 2 for conveying the pebble coal into the crusher body 2 for crushing. During use, the pebble coal material in the coal pile is moved to the upper hopper 1 by a forklift, and the pebble coal material falls from the discharge port at the bottom of the upper hopper 1 onto the belt of the belt conveyor 3. The belt conveyor 3 is then used to transport the pebble coal material to above the feed port 10 of the crusher body 2, allowing the pebble coal material to fall into the crusher body 2 for crushing and decomposition, thereby realizing automatic loading of the pebble coal material.

[0022] In this embodiment, a feed frame 4 is provided at the feed port 10 of the crusher body 2. A cavity 5 for the flow of gravel and coal is defined within the feed frame 4. This cavity 5 is connected to the crusher body 2, allowing gravel and coal fed by the belt conveyor 3 to enter the crusher body 2 through the cavity 5. A feed port 10 communicating with the cavity 5 is defined on the sidewall of the feed frame 4 proximal to the belt conveyor 3. The discharge end of the belt conveyor 3 engages with the interior of the feed port 10 and extends into the cavity 5, thereby establishing communication with the cavity 5. The belt conveyor 3 transports the gravel and coal to the feed port 10, where it falls into the cavity 5 under its own gravity, completing the conveyance of the gravel and coal.

[0023] In this embodiment, the cavity 5 is provided with a symmetrically arranged baffle plate 6 forming an inverted eight-shaped structure. The ends of the baffle plates 6 on both sides that are away from each other are rotatably connected to the cavity 5 by a common rotating shaft structure. The unloading end of the belt conveyor 3 is located above the baffle plates 6 on both sides to ensure that the gravel and coal materials can fall above the baffle plates 6 on both sides. Elastic buffer rods 7 with elasticity are rotatably installed between the lower end surfaces of the baffle plates 6 on both sides and the corresponding side walls of the cavity 5. The baffle plates 6 on both sides can be flipped inside the cavity 5 by the rotating shaft structure, and can perform corresponding reset actions inside the cavity 5 by the action of the corresponding elastic buffer rods 7. When the elastic buffer rods 7 on both sides are in normal state, a feeding channel 8 is left between the baffle plates 6 on both sides. The specific diameter of the feeding channel 8 can be selected and set according to actual conditions, and no excessive restrictions are imposed here. During use, the belt conveyor 3 conveys the gravel and coal materials into the feed frame 4. The gravel and coal materials fall under the action of their own gravity and accumulate on the baffle plate 6. Then, under the guidance of the baffle plate 6, they slide into the feed channel 8. The baffle plate 6 supports the gravel and coal materials that fall into the cavity 5, so as to prevent the gravel and coal materials from falling directly into the crusher, colliding with the crushing components, and splashing outside the crusher.

[0024] In this embodiment, a guide assembly 9 for guiding the gravel and coal materials in the feed channel 8 is further provided inside the cavity 5 below the feed channel 8. The guide assembly 9 includes a guide roller 91 rotatably provided in the cavity 5. The outer wall of the guide roller 91 is provided with a plurality of support plates 92 in a circumferential manner. The specific number of support plates 92 can be selected and set according to actual conditions. A clamping groove 93 for holding the gravel and coal materials is provided between each adjacent support plate 92, and the angle of each clamping groove 93 is 60°. The maximum diameter of the feed channel 8 can be smaller than the diameter of the guide roller 91 to ensure that the gravel and coal materials entering the feed channel 8 can fall onto the guide roller 91. The outer wall of the feed frame 4 is also provided with a motor for driving the guide roller 91 to rotate. The motor drives the guide roller 91 to rotate in the cavity 5 to guide the gravel and coal materials. By driving the guide roller 91 to rotate inside the cavity 5 through the motor, the gravel and coal materials in the clamping groove 93 can fall into the crusher body 2, so as to realize the dredging of the gravel and coal materials in the feeding channel 8, thereby achieving the purpose of controlling the feeding speed and quantity of the gravel and coal materials, avoiding the jamming of the crushing components due to excessive accumulation of gravel and coal materials, and improving the crushing efficiency and effect. Moreover, since the maximum diameter of the feeding channel is smaller than the diameter of the guide roller 91, the flipping of the baffle plates 6 on both sides will not interfere with the guide roller 91, thereby ensuring the use of the baffle plates 6 and the guide roller 91.

[0025] When the spring 74 is compressed and contracts, the two end plates 73 will pull the telescopic inner rod 72 back to its original position under the action of the spring 74 itself, so that the baffle plate 6 can be pushed upward, thereby realizing the resetting of the baffle plate 6. The telescopic sleeve 71 and the telescopic inner rod 72 are further provided with connecting ears 75 on the ends away from each other, and the first rotating shaft seats 11 are provided on the lower end surfaces of the baffle plates 6 on both sides and the side walls of the cavity 5 on both sides. The telescopic sleeve 71 is rotatably connected to the first rotating shaft seats 11 at the corresponding position through the connecting ears 75 to be rotatably connected to the baffle plate 6, and the telescopic inner rod 72 is rotated with the first rotating shaft seats 11 at the corresponding position through the connecting ears 75 to be rotatably connected to the cavity 5, so that when the baffle plate 6 is flipped, the telescopic sleeve 71 and the telescopic inner rod 72 can perform corresponding movements so as not to interfere with the normal flipping work of the baffle plate 6.

[0026] By the arrangement of the elastic buffer rod 7, when the material jam occurs in the feeding channel 8, the stone and coal materials will continue to accumulate on the material retaining plate 6, which can be pressed to flip and tilt the material retaining plate 6 in the cavity 5, thereby expanding the feeding channel 8, so that the stone and coal materials stuck in the feeding channel 8 can pass through the feeding channel 8. In this process, the rear spring 74 in the elastic buffer rod 7 is forced to contract to generate a reset force, and the telescopic inner rod 72 slides along the telescopic sleeve 71 accordingly. The telescopic inner rod 72 and the telescopic sleeve 71 flip accordingly under the action of the first rotating shaft seat 11. After the feeding channel 8 is unblocked, the weight of the stone and coal materials on the material retaining plate 6 becomes lighter. At this time, the elastic buffer rod 7 can make the material retaining plate 6 rebound to restore the feeding channel 8 to its original state, thereby avoiding the situation where the stone and coal materials are discharged too quickly due to the excessive diameter of the feeding channel 8, so as to ensure that the crushing assembly is not easily jammed.

[0027] In this embodiment, a slot 76 is further defined within the telescopic sleeve 71, and the telescopic inner rod 72 is slidably mounted within the slot 76. An end cap 77 for closing the slot 76 is provided on the end of the telescopic sleeve 71 proximal to the telescopic inner rod 72. A sliding hole 78 is defined in the end cap 77, and the telescopic inner rod 72 is disposed so as to extend through the sliding hole 78. A limit stopper 79 is provided on the end of the telescopic inner rod 72 located within the slot 76, and the limit stopper 79 is configured to prevent the telescopic inner rod 72 from sliding within the sliding hole 78 from passing through the sliding hole 78. The position of the limit stopper 79 is limited by the end cap 77, thereby preventing the telescopic inner rod 72 from sliding within the sliding hole 78 from disengaging from the slot 76, thereby preventing the elastic buffer rod 7 from becoming unusable due to the telescopic inner rod 72 disengaging from the telescopic sleeve 71, thereby ensuring the use of the elastic buffer rod 7.

[0028] In the first embodiment, the blockage in the material passage 8 is cleared only by the elastic buffer rod 7 and the gravity of the stone and coal materials accumulated on the material retaining plate 6. However, the blockage is not cleared in time, which has a significant impact on the crushing efficiency of the stone and coal materials. Therefore, based on the first embodiment, the second embodiment is proposed.

[0029] Example 2: Please refer to Figures 6-10This embodiment provides a new type of stone coal crusher, including all the structures of the first embodiment. Furthermore, a plurality of detection components 12 are provided in the material guide component 9. The specific number of the detection components 12 can be selected and set according to actual conditions. In this embodiment, only one detection component 12 is required. The detection assembly 12 includes a first detection shell 121 embedded in one side wall of one of the support plates 92, an infrared sensor emitting end 122 is provided in the first detection shell 121, and a first through hole 123 is provided on the end of the first detection shell 121 away from the corresponding support plate 92, the infrared light emitted by the infrared sensor emitting end 122 can be emitted outward from the first through hole 123 and emitted to the wall of another adjacent support plate 92 in the same clip groove 93, a second detection shell 124 is embedded in the wall of this support plate 92, an infrared sensor receiving end 125 is provided in the second detection shell 124, and a second through hole 126 is provided on the end of the second detection shell 124 close to the first detection shell 121, the infrared light emitted by the infrared sensor emitting end 122 is emitted outward from the first through hole 123 and enters the second through hole 126 and is received by the infrared sensor receiving end 125. Through the above-mentioned configuration, the detection assembly 12 can detect whether there is an object in the corresponding clamping groove 93. If there is no object in the clamping groove 93 for a long time, this indicates that the stone coal material may be blocked in the feeding channel 8, resulting in the stone coal material being unable to fall into the clamping groove 93. To enhance the detection effect, a convex lens can also be provided in the first detection housing 121. The convex lens is provided between the first through hole 123 and the infrared sensor transmitting end 122. The infrared light emitted by the infrared sensor transmitting end 122 is first concentrated by the convex lens before being emitted outward from the first through hole 123 to ensure the light intensity, thereby ensuring the accuracy of the detection effect. At the same time, the first detection housing 121 located above the first through hole 123 and the second detection housing 124 located above the second through hole 126 can also be provided with a protective cover with a cleaning structure. The provision of the protective cover can prevent the stone coal material from directly hitting the first through hole 123 and the second through hole 126, causing residue to be stuck in the first through hole 123 and the second through hole 126, thereby affecting the detection effect.

[0030] In conjunction with the setting of the detection component 12, in this embodiment, a pull rod component 13 is also provided between the lower end surface of the two side baffles 6 and the corresponding side wall of the cavity 5, which can pull the baffle plate 6 to swing toward the corresponding side wall of the cavity 5. The pull rod component 13 is electrically connected to the infrared sensor receiving end 125. The infrared sensor receiving end 125 generates an electrical signal after not receiving infrared light. After receiving this electrical signal, the pull rod component 13 pulls the baffle plate 6 to swing toward the corresponding side wall of the cavity 5, so as to expand the diameter of the feed channel 8 and realize the dredging of the feed channel 8, so that the stone and coal materials stuck in the feed channel 8 can quickly pass through the feed channel 8, realizing timely dredging of the feed channel 8, thereby ensuring the crushing efficiency of the stone and coal materials by this crusher.

[0031] In this embodiment, the rod assembly 13 includes a rod sleeve 131, and a rod body 132 is slidably provided in the inner cavity of the rod sleeve 131. The end of the rod body 132 away from the rod sleeve 131 extends to the outside of the rod sleeve 131 in a movable manner. The ends of the rod sleeve 131 and the rod body 132 away from each other are both rotatably connected to the lower end surface of the baffle plate 6 at the corresponding position and the corresponding side wall of the cavity 5 by providing a second rotating shaft seat 133, so as to adapt to the subsequent flipping movement of the baffle plate 6. A limit block 134 is provided on the end of the rod body 132 located inside the rod sleeve 131, and a limit step 135 is provided on the end of the rod sleeve 131 close to the rod body 132. The limit block 134 is set so that it cannot pass through the limit step 135, thereby preventing the rod body 132 from slipping out of the rod sleeve 131. A magnetostrictive ring 136 is provided in the end of the pull rod sleeve 131 close to the pull rod body 132, and the pull rod body 132 is arranged to movably pass through the magnetostrictive ring 136. The rod wall of the pull rod body 132 is gradually expanded outward in the direction close to the pull rod sleeve 131. A battery 137 electrically connected to the magnetostrictive ring 136 is also provided on the outer wall of the telescopic sleeve 71. The battery 137 is provided with a control module electrically connected to the infrared sensor receiving end 125. After receiving the electrical signal generated by the infrared sensor, the control module controls the battery 137 to discharge. After the battery 137 is energized, the magnetostrictive ring 136 contracts under the action of the current so as to squeeze the rod wall of the pull rod body 132 and make it move in the direction close to the pull rod sleeve 131, so that the corresponding material baffle 6 can be pulled and flipped in the direction close to the corresponding side wall of the cavity 5, thereby achieving the expansion of the diameter of the material passage 8. After the infrared sensor receiving end 125 receives the infrared light emitted by the infrared sensor transmitting end 122, the infrared sensor receiving end 125 stops generating electrical signals, and the control module controls the battery 137 to stop discharging after not receiving the electrical signal. At this time, the magnetostrictive ring 136 will recover and expand accordingly after being de-energized, so that the pull rod body 132 can move freely through the magnetostrictive ring 136 without being affected by the magnetostrictive ring 136, so as to adapt to the flipping movement of the material baffle 6 and the telescopic movement of the elastic buffer rod 7, so that the pull rod assembly 13 will not affect the movement of the material baffle 6 and the elastic buffer rod 7 when it is not powered.
