Description
Technical Field
[0001] This utility model relates to the field of coal feeding technology, and in particular to a feeding device for a coal sample preparation machine. Background Technology
[0002] A feeding device for a coal-fired sample preparation machine is a transitional component connecting the coal raw material and the sample preparation system. It consists of a storage hopper, a quantitative conveying mechanism, a flow regulating valve, and an anti-clogging component. The hopper temporarily stores the coal to be processed, the conveying mechanism feeds the coal at a set rate, the regulating valve precisely controls the feed amount, and the anti-clogging component can prevent the coal from caking and blocking. The whole device is modularly designed to meet the raw material conveying needs of continuous operation of the sample preparation machine.
[0003] The core function of the feeding device of a coal-fired sample preparation machine is to provide a stable and controllable supply of raw materials for the sample preparation process. First, by feeding the material evenly, it avoids the impact of raw material quantity fluctuations on crushing and grinding accuracy, ensuring accurate sample preparation results. Second, the anti-clogging design reduces equipment downtime, improves sample preparation efficiency, and at the same time can buffer the impact of raw materials, protect subsequent sample preparation components, and extend the service life of the whole machine.
[0004] A feeding device for a coal sample preparation machine has a significant shortcoming. The core problem is that the feed inlet has no size adjustment function and can only be adapted by constantly changing different sizes of feed inlets. This means that when dealing with coal of different particle sizes or adjusting the sample preparation feed rate, it is necessary to stop the machine to disassemble and replace parts. This not only interrupts the operation process, prolongs the sample preparation time, and reduces the overall efficiency, but also causes wear and tear on the feed inlet seals due to frequent disassembly and assembly, increasing the cost of component wear. Utility Model Content
[0005] To overcome the above shortcomings, this utility model provides a feeding device for a coal-fired sample preparation machine, which aims to improve the problem that the feed inlet in the prior art has no size adjustment function and can only be adapted by constantly changing feed inlets of different specifications.
[0006] To achieve the above objectives, the present invention adopts the following technical solution: a feeding device for a coal-fired sample preparation machine, comprising a crusher and a feeding trough, wherein a pushing mechanism is provided on the upper right side of the feeding trough, the pushing mechanism being used to adjust the size of the feeding inlet, a flow speed control mechanism is provided at the bottom of the feeding trough, the flow speed control mechanism being used to adjust the feeding speed at the feeding inlet, a discharge mechanism is provided at the bottom of the crusher, and a moving mechanism is provided at the bottom of the discharge mechanism; The pushing mechanism includes a partition plate, the top right side of which is rotatably connected to the inside right side of the feed trough.

Multiple stabilizing components are provided around the outer wall of the feed trough, and mounting components are provided at the bottom of each of the multiple stabilizing components.
[0008] As a further description of the above technical solution: The discharge mechanism includes a base plate, the top of which is fixedly connected to the bottom of the crusher, and a discharge port is provided inside the base plate.
[0009] As a further description of the above technical solution: The moving mechanism includes multiple connecting frames, the tops of which are fixedly connected to the bottom perimeter of the base plate, and wheels are rotatably connected to the bottom of each connecting frame.
[0010] As a further description of the above technical solution: The vibration assembly includes two mounting rings, the left sides of which are fixedly connected to the right side of the feed chute, and the same vibrator is installed on the inner wall of both mounting rings.
[0011] As a further description of the above technical solution: The opening and closing assembly includes a cover, the bottom of which is installed on the top of the feed trough.

[0013] As a further description of the above technical solution: The stabilizing components include multiple brackets, each bracket having a connecting rod fixedly connected to its bottom, and each connecting rod having a thick spring installed on its outer wall.
[0014] This utility model has the following beneficial effects: 1. In this utility model, the top feeding channel of the feeding trough is opened by the opening and closing component. The rotating handle of the rotating push mechanism drives the threaded rod to rotate, and the threaded rod drives the push rod to move. The push rod slides along the guide rails on the front and rear sides of the partition plate through the slider, thereby driving the partition plate to rotate around the right side of the inside of the feeding trough to adjust the size of the feeding port. The vibration component is activated to prevent the raw material from accumulating in the feeding trough. The flow speed control mechanism adjusts the speed at which the raw material enters the crusher. The crushed raw material is discharged through the discharge mechanism.

The flow control plate slides inside the placement groove to change the overlapping area with the discharge channel at the bottom of the feed trough, thereby adjusting the material passing speed. After the position is determined, the triangular bolt is passed through the front side of the flow control plate, and then the flow control plate is tightened and fixed with the threaded connection of the nut. The stabilizing components around the outer wall of the feed trough assist in stabilizing the structure, and the installation components at the bottom fix the stabilizing components, reducing the impact of vibration and impact. This achieves precise and controllable speed of material entering the crusher, avoiding the crusher from being overloaded and blocked due to excessive speed or affected by efficiency due to excessively slow speed. It also enhances the structural stability of the feed trough, prevents the device from shifting due to vibration, and ensures continuous and stable feeding and crushing processes.

[0018] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0019] Reference Figures 1-5 An embodiment of this utility model is provided: a feeding device for a coal-fired sample preparation machine, including a crusher 1 and a feeding trough 2. A pushing mechanism 3 is provided on the upper right side of the feeding trough 2. The pushing mechanism 3 is used to adjust the size of the feeding inlet. A flow speed control mechanism 4 is provided at the bottom of the feeding trough 2. The flow speed control mechanism 4 is used to adjust the feeding speed of the feeding inlet. A discharge mechanism 5 is provided at the bottom of the crusher 1. A moving mechanism 6 is provided at the bottom of the discharge mechanism 5. The pushing mechanism 3 includes a partition plate 31. The top right side of the partition plate 31 is rotatably connected to the inside right side of the feed trough 2. Two guide rails 32 are fixedly connected to the front and rear sides of the partition plate 31. Slider 33 is slidably connected to the right side of the two guide rails 32. Push rods 34 are slidably connected inside the two sliders 33. The same threaded rod 35 is threaded inside the two push rods 34. Rotating handle 36 is threadedly connected to the right side of the threaded rod 35. A vibration component 37 is provided in the upper middle part of the right side of the feed trough 2. An opening and closing component 38 is provided at the top of the feed trough 2. Specifically, the opening and closing assembly 38 at the top of the feed trough 2 controls the opening of the feed channel at the top of the feed trough 2. The coal raw material enters the feed trough 2 through the opened feed channel. When it is necessary to adjust the size of the feed opening, the rotating handle 36 in the push mechanism 3 is operated. The rotating handle 36 drives the threaded rod 35 to rotate. Since the threaded rod 35 and the two push rods 34 are all threadedly connected, the rotation of the threaded rod 35 will drive the two push rods 34 to move along their own axis. At the same time, the push rod 34 is slidably connected to the slider 33, the slider 33 is slidably connected to the guide rail 32, and the guide rail 32 is fixedly connected. On the front and rear sides of the partition plate 31, the top right side of the partition plate 31 is rotatably connected to the inside right side of the feed trough 2. The movement of the push rod 34 will drive the partition plate 31 to rotate around the rotation point at its top right side through the cooperation of the slider 33 and the guide rail 32. Through the linkage of this series of components, the size of the feed inlet can be adjusted. During the process of the raw material moving down along the feed trough 2, the vibration component 37 in the upper middle part of the right side of the feed trough 2 is activated. The vibration generated by the vibration component 37 is transmitted to the feed trough 2. In conjunction with the internal channel structure of the feed trough 2, the raw material is prevented from accumulating and blocking in the feed trough 2, ensuring that the raw material moves down smoothly and continuously. When the raw material moves to the bottom of the feed trough 2, the flow control mechanism 4 starts to work. Through the adjustment of the discharge channel at the bottom of the feed trough 2, the flow control mechanism 4 controls the speed at which the raw material enters the crusher 1 through this channel. This avoids the crusher 1 from being overloaded and blocked due to the raw material entering too quickly, or from being too slow and affecting the sample preparation efficiency. Through the cooperation between the flow control mechanism 4 and the bottom channel of the feed trough 2, the feeding speed is precisely controlled. After the raw material enters the crusher 1, the crusher 1 crushes the raw material. The crushed raw material falls into the discharge mechanism 5 at the bottom of the crusher 1. The discharge mechanism 5, through its own structural design, discharges the crushed raw material outward, completing the crushing and discharge process. In addition, when it is necessary to adjust the working position of the entire feeding device and the crusher 1, the moving mechanism 6 at the bottom of the discharge mechanism 5 is activated. Through the operation of the moving mechanism 6, the entire device is moved, realizing the switching of the device in different working areas. Through the cooperation between the moving mechanism 6 and the overall structure of the device, the flexibility of the device is improved.
[0020] Reference Figures 1-5 The flow control mechanism 4 includes a placement groove 41, the rear top of the placement groove 41 is installed at the bottom of the feed trough 2, a flow control plate 42 is slidably connected inside the placement groove 41, a triangular bolt 43 is threadedly connected inside the front side of the flow control plate 42, a nut 44 is threadedly connected to the bottom of the triangular bolt 43, and multiple stabilizing components 46 are provided around the outer wall of the feed trough 2, and mounting components 45 are provided at the bottom of the multiple stabilizing components 46. Specifically, the feeding channel is opened by the opening and closing component 38 at the top of the feeding trough 2, and the coal raw material enters the feeding trough 2. When the size of the feeding port is adjusted, the rotating handle 36 of the pushing mechanism 3 is operated to drive the threaded rod 35 to rotate. The threaded rod 35 drives the two push rods 34 to move. The push rods 34 slide along the guide rail 32 through the sliding cooperation with the slider 33. The guide rail 32 is fixed on the front and rear sides of the partition plate 31. The top right side of the partition plate 31 is rotatably connected to the right side inside the feeding trough 2, and finally drives the partition plate 31 to rotate around the rotation point. Through the cooperation of this series of components, the size of the feeding port can be adjusted. At the same time, the vibration component 37 in the upper middle part of the right side of the feeding trough 2 is activated, and the vibration is transmitted to the feeding trough 2 to avoid the accumulation and blockage of raw materials. Through the cooperation of the vibration component 37 and the feeding trough 2, the raw materials can move smoothly downward. When the raw material moves to the bottom of the feed trough 2, the flow control mechanism 4 starts to operate. The top rear side of the placement trough 41 is installed at the bottom of the feed trough 2. The flow control plate 42, which is slidably connected inside the placement trough 41, can slide along the placement trough 41. By pushing the flow control plate 42, its position in the placement trough 41 is changed, adjusting the overlapping area of the placement trough 41 and the bottom discharge channel of the feed trough 2. After adjusting to the target position, the triangular bolt 43 is passed through the front interior of the flow control plate 42, and then the nut 44 is threaded onto the bottom of the triangular bolt 43 and tightened. The flow control mechanism is fixed by the cooperation of the triangular bolt 43 and the nut 44. The position of the plate 42 is used to stabilize and control the speed at which the raw material enters the crusher 1. Through the linkage of the flow control plate 42, triangular bolts 43, nuts 44 and placement groove 41, the feeding speed can be precisely controlled. In addition, multiple stabilizing components 46 around the outer wall of the feeding trough 2 can enhance the structural stability of the feeding trough 2. The bottom of each of the multiple stabilizing components 46 is provided with mounting components 45. By cooperating with the mounting surface, the stabilizing components 46 are fixed, thereby improving the stability of the feeding trough 2 during the raw material conveying process and preventing the feeding trough 2 from being displaced due to vibration or raw material impact. After the raw material enters the crusher 1 at the controlled speed, the crusher 1 crushes the raw material. The crushed raw material falls into the discharge mechanism 5, which discharges the raw material outward. When the position of the device needs to be adjusted, the moving mechanism 6 is started, which drives the entire device to move. Through the cooperation of the moving mechanism 6 and the whole device, the device can switch between different working areas.
[0021] Reference Figures 1-2 The discharge mechanism 5 includes a base plate 51, the top of which is fixedly connected to the bottom of the crusher 1. The discharge port 52 is opened inside the base plate 51. The moving mechanism 6 includes multiple connecting frames 61, the tops of which are fixedly connected to the bottom of the base plate 51 around the perimeter. The bottoms of the multiple connecting frames 61 are rotatably connected to wheels 62. The vibration assembly 37 includes two mounting rings 371, the left sides of which are fixedly connected to the right side of the feed chute 2. The same vibrator 372 is installed on the inner wall of both mounting rings 371. Specifically, the feeding channel is opened by the opening and closing component 38 at the top of the feeding trough 2, allowing the coal raw material to enter the feeding trough 2. When the size of the feeding inlet is adjusted, the rotating handle 36 of the pushing mechanism 3 is operated, causing the threaded rod 35 to rotate. The threaded rod 35 drives the two push rods 34 to move. The push rods 34 slide along the guide rails 32 fixed to the front and rear sides of the partition plate 31 through sliding cooperation with the slider 33. The top right side of the partition plate 31 is rotatably connected to the right side inside the feeding trough 2, ultimately causing the partition plate 31 to rotate. The moving point rotates, and the size of the feed inlet is adjusted through the cooperation of the partition plate 31, guide rail 32, slider 33, push rod 34 and threaded rod 35. Then, the vibration assembly 37 is started. The two mounting rings 371 are fixedly connected to the right side of the feed trough 2 on the left side. The same vibrator 372 installed on the inner wall of the two rings generates vibration. The vibration is transmitted to the feed trough 2 through the mounting rings 371. Through the cooperation of the vibrator 372, the mounting rings 371 and the feed trough 2, the raw material is prevented from accumulating and blocking in the feed trough 2, and the raw material is ensured to move continuously downward. When the raw material moves to the bottom of the feed trough 2, the flow control mechanism 4 operates. The top of the rear side of the placement trough 41 is installed at the bottom of the feed trough 2. The flow control plate 42, which is slidably connected inside, slides along the placement trough 41, changing the overlapping area with the discharge channel at the bottom of the feed trough 2. After adjustment, the triangular bolt 43 is passed through the front side of the flow control plate 42, and the nut 44 is threaded to the bottom of the triangular bolt 43 and tightened. Through the cooperation of the flow control plate 42, the triangular bolt 43, the nut 44 and the placement trough 41, the position of the flow control plate 42 is fixed, realizing precise control of the feed speed. After the raw material enters the crusher 1 at the controlled speed, the crusher 1 crushes the raw material. The crushed raw material falls into the discharge mechanism 5, and the top of the bottom plate 51 is fixed. Connected to the bottom of the crusher 1, the discharge port 52 inside receives the crushed raw material. Through the cooperation of the bottom plate 51 and the discharge port 52, the raw material is discharged outward. In addition, multiple stabilizing components 46 around the outer wall of the feed trough 2 enhance the structural stability of the feed trough 2. The mounting components 45 at the bottom of the multiple stabilizing components 46 cooperate with the mounting surface to fix the stabilizing components 46, further improving the stability of the feed trough 2. When the position of the device needs to be adjusted, the moving mechanism 6 is activated. The tops of multiple connecting frames 61 are respectively fixedly connected to the bottom of the bottom of the bottom plate 51. The wheels 62 connected to the bottom of the frame 61 rotate and roll. Through the cooperation of the connecting frames 61 and the wheels 62, the entire device is moved, realizing the switching of the device in different working areas.
[0022] Reference Figures 1-4The opening and closing assembly 38 includes a cover 381, the bottom of which is installed on the top of the feed chute 2. A buckle 382 is fixedly connected to the right side of the cover 381, and a slot 383 is provided on the right side of the buckle 382. Two hinges 384 are fixedly connected to the left side of the cover 381. The mounting assembly 45 includes multiple mounting plates 451, the bottom of which is installed around the top of the crusher 1. Multiple threads 452 are threaded to the front and rear sides of the multiple mounting plates 451. The stabilizing assembly 46 includes multiple brackets 461, the bottom of which is fixedly connected to a connecting rod 462. A coarse spring 463 is installed on the outer wall of the multiple connecting rods 462. Specifically, first operate the opening and closing component 38. The bottom of the cover 381 is installed on the top of the feed trough 2. Two hinges 384 fixedly connected to its left side can drive the cover 381 to rotate. Through the cooperation between the cover 381 and the hinges 384, the feed channel at the top of the feed trough 2 is opened. The buckle 382 fixedly connected to the right side of the cover 381 engages with the corresponding slot 383. Through the cooperation between the buckle 382 and the slot 383, the position of the cover 381 is fixed, preventing the cover 381 from shifting when raw materials are fed. The coal raw material passes through the opening and closing mechanism. The feed channel opens into the feed trough 2. If the size of the feed opening needs to be adjusted, the rotating handle 36 of the push mechanism 3 is operated to drive the threaded rod 35 to rotate. The threaded rod 35 drives the two push rods 34 to move. The push rods 34 and the slider 33 slide together, causing the slider 33 to slide along the guide rails 32 fixed on the front and rear sides of the partition plate 31. The top right side of the partition plate 31 is rotatably connected to the right side of the feed trough 2. Through the cooperation of the partition plate 31, the guide rail 32, the slider 33, the push rods 34 and the threaded rod 35, the size of the feed opening can be adjusted. When the vibration assembly 37 is activated, the two mounting rings 371 are fixedly connected to the right side of the feed trough 2 on the left side. The same vibrator 372 installed on the inner wall of the vibrator 371 generates vibration. The vibration is transmitted to the feed trough 2 through the mounting rings 371. Through the cooperation of the vibrator 372, the mounting rings 371 and the feed trough 2, the raw material is prevented from accumulating and blocking in the feed trough 2. When the raw material moves down to the bottom of the feed trough 2, the flow control mechanism 4 operates. The top of the rear side of the placement trough 41 is installed at the bottom of the feed trough 2. The flow control plate 42, which is internally slidably connected, slides along the placement trough 41, changing the overlapping area with the discharge channel at the bottom of the feed trough 2. The triangular bolt 43 passes through the front interior of the flow control plate 42. The nut 44 is threadedly connected to the bottom of the triangular bolt 43 and tightened. Through the cooperation of the flow control plate 42, the triangular bolt 43, the nut 44 and the placement trough 41, the position of the flow control plate 42 is fixed, and the feeding speed is precisely controlled. After the raw material enters the crusher 1 at the controlled speed, the crusher 1 crushes the raw material. The crushed raw material falls into the discharge mechanism 5. The top of the bottom plate 51 is fixedly connected to the bottom of the crusher 1, and the discharge port 52 inside the bottom plate 51 receives the raw material. Through the cooperation between the bottom plate 51 and the discharge port 52, the raw material is discharged outward. At the same time, the stabilizing components 46 around the outer wall of the feed chute 2 are activated. The connecting rods 462, which are fixedly connected to the bottom of multiple supports 461, are fitted with coarse springs 463 on their outer walls. Through the cooperation between the supports 461, the connecting rods 462, and the coarse springs 463, the material is buffered. The impact of raw material impact and vibration on the feed trough 2 is addressed by mounting multiple mounting plates 451 at the bottom of the mounting assembly 45 around the top of the crusher 1. Multiple threads 452 connected to the front and rear sides of the mounting plate 451 are fixed to the mounting surface. Through the cooperation of the mounting plate 451 and the threads 452, the assembly 46 is fixed and stabilized, further enhancing the stability of the feed trough 2. When the device position needs to be adjusted, the wheels 62 connected to the bottom of the multiple connecting frames 61 of the moving mechanism 6 rotate. Through the cooperation of the connecting frames 61 and the wheels 62, the entire device is moved, realizing the switching of the working area.
[0023] Working principle: Before starting the device, the feeding preparation work is completed first. The opening and closing component 38 is operated to open the top feeding channel of the feeding trough 2. The bottom of the cover 381 of the opening and closing component 38 is installed on the top of the feeding trough 2. Two hinges 384 are fixedly connected to the left side of the cover 381. The rotation characteristics of the hinges 384 drive the cover 381 to rotate around the axis of the hinges 384, so that the cover 381 is released from the covered state of the top of the feeding trough 2, thereby opening the feeding channel at the top of the feeding trough 2. After the cover 381 is rotated to the target opening angle, the cover 381... The buckle 382 fixedly connected on the right side engages with the corresponding slot 383 set in the feed trough 2. Through the engagement of the buckle 382 and the slot 383, the current position of the cover 381 is fixed, preventing the cover 381 from shifting due to vibration or impact of raw materials during subsequent raw material feeding. This ensures that the feed channel is continuously and stably open. Through the synergistic effect of the cover 381, hinge 384, buckle 382 and slot 383, the controllable opening and fixed position of the feed channel at the top of the feed trough 2 are achieved, preparing for the coal raw material to enter the feed trough 2. After the coal feedstock enters the feed trough 2 through the open feed channel, the size of the feed inlet can be adjusted by the push mechanism 3 according to the particle size of the feedstock and the feeding requirements. Operating the rotating handle 36 on the right side of the push mechanism 3 causes the threaded rod 35 to rotate synchronously as it is threaded to the right side of the threaded rod 35. The threaded rod 35 passes through two push rods 34 and is threaded to both of them. The rotation of the threaded rod 35 drives the two push rods 34 to move in opposite directions along their own axes. Simultaneously, the push rods 34 are slidably connected to the slider 33, and the slider 33 is slidably connected to the guide rail 32. The guide rail 32 is fixedly connected to the front and rear sides of the partition plate 31. The top right side of the partition plate 31 is rotatably connected to the inside right side of the feed trough 2. The movement of 34 is transmitted to the guide rail 32 through the slider 33, causing the slider 33 to slide along the guide rail 32, which in turn pushes the partition plate 31 to rotate around the rotation point on its right top, so that the width of the feed inlet formed between the partition plate 31 and the inner wall of the feed trough 2 changes. When the partition plate 31 rotates to the target angle and the size of the feed inlet meets the current raw material feeding requirements, the rotating handle 36 stops rotating, the threaded rod 35 stops rotating, and the positions of the push rod 34, slider 33, guide rail 32 and partition plate 31 remain fixed. Through the linkage of rotating handle 36, threaded rod 35, push rod 34, slider 33, guide rail 32 and partition plate 31, the feed inlet is precisely adjusted to ensure that the size of the feed inlet is compatible with the particle size of the raw material and to avoid the raw material from being blocked due to the feed inlet being too small or losing control of the feed due to the feed inlet being too large. As the raw material moves downward along the internal channel of the feed trough 2, to prevent the raw material from accumulating and blocking inside the feed trough 2, the vibration component 37 located on the upper right side of the feed trough 2 is activated. The two mounting rings 371 of the vibration component 37 are fixedly connected to the right side of the feed trough 2 on their left sides. The same vibrator 372 is installed on the inner wall of the two mounting rings 371. After the vibrator 372 is activated, it generates vibration energy, which is transmitted to the side wall of the feed trough 2 through the mounting rings 371, and then to the internal channel of the feed trough 2. The vibration causes the raw material particles inside the feed trough 2 to jump slightly, breaking the adsorption and friction between the raw material particles, preventing the raw material from forming an accumulation layer on the inner wall of the feed trough 2, and ensuring that the raw material can move smoothly and continuously along the internal channel of the feed trough 2. Through the cooperation of the vibrator 372, the mounting rings 371 and the feed trough 2, the anti-blocking effect of the raw material during the conveying process is achieved, ensuring the continuity of the feeding process. As the raw material continues to move down to the bottom of the feed trough 2, the flow control mechanism 4 starts to work to control the speed at which the raw material enters the crusher 1. The top of the rear side of the placement trough 41 of the flow control mechanism 4 is installed at the bottom of the feed trough 2. A flow control plate 42 is slidably connected inside the placement trough 41. The flow control plate 42 can slide along the length of the placement trough 41. By manually pushing the flow control plate 42 to change its position in the placement trough 41, the overlapping area between the flow control plate 42 and the discharge channel at the bottom of the feed trough 2 can be adjusted. The larger the overlapping area, the larger the effective diameter of the discharge channel, and the faster the raw material passes through. The smaller the overlapping area, the smaller the effective diameter of the discharge channel, and the slower the raw material passes through. Once the flow control plate 42 is adjusted to the target position, the raw material... When the material passes through the crusher 1 at a speed that meets the processing requirements, the triangular bolt 43 is passed through the threaded hole inside the front side of the flow control plate 42, and the nut 44 is threaded onto the bottom of the triangular bolt 43. The nut 44 is then tightened clockwise so that the triangular bolt 43 and the nut 44 together clamp the flow control plate 42 and the placement groove 41, fixing the current position of the flow control plate 42 and preventing the flow control plate 42 from shifting under the impact of the material. Through the cooperation of the flow control plate 42, the placement groove 41, the triangular bolt 43 and the nut 44, the speed at which the material enters the crusher 1 is precisely controlled. This prevents the crusher 1 from being overloaded and blocked due to the material entering too quickly, and also prevents the sample preparation efficiency from being affected by the speed being too slow, ensuring that the crusher 1 is always in a stable working state. After the raw material enters the crusher 1 through the discharge channel at the bottom of the feed trough 2 at the controlled speed, the crusher 1 starts and crushes the raw material. The crusher 1 applies impact or extrusion force to the incoming coal raw material through the internally preset crushing components, crushing the raw material with larger particle size to the particle size that meets the sample preparation requirements. After the crushing process is completed, the crushed raw material falls from the bottom outlet of the crusher 1 into the discharge mechanism 5 set below it under its own gravity. The bottom plate 51 of the discharge mechanism 5 is fixedly connected to the bottom of the crusher 1. The bottom plate 51 has a discharge port 52 inside, which corresponds vertically to the bottom outlet of the crusher 1. After the crushed raw material falls onto the upper surface of the bottom plate 51, it slides along the inclined structure of the bottom plate 51 to the discharge port 52, and then is discharged downward to the external receiving device through the discharge port 52, completing the crushing and discharge process of the raw material. Through the cooperation of the crusher 1, the bottom plate 51 and the discharge port 52, the raw material is transformed from coarse material to fine material and collected, providing the raw material that meets the requirements for the sample preparation process. Multiple stabilizing components 46 arranged around the outer wall of the feed trough 2 work together with the mounting components 45 to ensure the structural stability of the device. Multiple supports 461 of the stabilizing components 46 are fixedly connected to the outer wall of the feed trough 2. Each support 461 has a connecting rod 462 fixedly connected to its bottom. A coarse spring 463 is installed on the outer wall of the connecting rod 462. When the feed trough 2 shakes due to vibration of the vibration component 37 or impact from raw materials, the coarse spring 463 absorbs the shaking energy through its elastic deformation. The connecting rod 462 then transmits this buffering force. The supports 461 transfer the buffering effect to the feed trough 2, reducing the shaking amplitude of the feed trough 2 and preventing long-term shaking at the connection between the feed trough 2 and the crusher 1. If loosening occurs, the bottom of the multiple mounting plates 451 of the mounting assembly 45 are respectively installed around the top of the crusher 1. Each mounting plate 451 has multiple threads 452 threaded on its front and rear sides. The threads 452 are screwed into the pre-set threaded holes on the mounting surface to fix the position of the mounting plate 451. Then, the mounting plate 451 fixes the bottom support point of the stabilizing assembly 46, so that the stabilizing assembly 46 can continuously and stably play a buffering role. Through the bracket 461, the connecting rod 462, the coarse spring 463, the cooperation of the mounting plate 451 and the threads 452, the structure of the feed chute 2 and the crusher 1 is stabilized, avoiding displacement of the device due to vibration or impact during operation, and ensuring the coordination accuracy of each mechanism. When the working position of the entire feeding device and crusher 1 needs to be adjusted, the moving mechanism 6 set at the bottom of the discharge mechanism 5 is activated. The tops of the multiple connecting frames 61 of the moving mechanism 6 are fixedly connected to the bottom of the base plate 51 around the perimeter. Each connecting frame 61 is rotatably connected to a wheel 62 at its bottom. The wheel 62 can roll freely around the rotation axis at the bottom of the connecting frame 61. By manually pushing the crusher 1 or the feeding chute 2, a horizontal thrust is applied to the entire device. This thrust is transmitted to the connecting frame 61, causing the wheel 62 to roll on the mounting surface, thereby moving the entire device along the direction of the thrust. After the device moves to the target working position, the thrust is stopped, the wheel 62 stops rolling, and the device position is fixed. Through the cooperation of the connecting frame 61 and the wheel 62, the device can be flexibly switched between different working areas, improving the ease of use and site adaptability of the device, and meeting the position requirements of different sample preparation scenarios.
