Description

Technical Field

[0001] This invention relates to the field of soil improvement technology, and more particularly to a coal gangue-based organic carbon soil conditioner and a fluidization device. Background Technology

[0002] Coal gangue is a solid waste generated during coal mining and washing. Large-scale stockpiling of coal gangue not only wastes valuable land resources but also poses a risk of spontaneous combustion and environmental pollution. However, coal gangue is also an important secondary resource that can be used to produce building materials, generate electricity, and extract rare metals, thus achieving resource reuse. But the amount of coal gangue consumed by these methods is small, resulting in a rate of coal gangue consumption that is lower than the rate of coal gangue production, meaning that the problem of coal gangue accumulation occupying land resources has not been completely solved.

[0003] my country has actively explored various ways to effectively utilize coal gangue, aiming to reduce environmental pollution while promoting the development of a circular economy. Since the elemental composition of coal gangue is similar to that of soil, only the content is different, coal gangue can also be used as a soil conditioner to increase soil fertility. Through these measures, not only can the environmental problems caused by coal gangue be solved, but waste can also be turned into treasure and new economic value can be created.

[0004] However, most existing methods for applying coal gangue to improve soil use involve using solid coal gangue, which requires transportation by vehicle, resulting in high transportation costs, low efficiency, and high difficulty. Therefore, existing methods cannot effectively utilize coal gangue as a soil conditioning and improvement component on a large scale. Summary of the Invention

[0005] This invention provides a coal gangue-based organic carbon soil conditioner and a fluidization device to overcome the problem of low utilization of existing coal gangue, which leads to coal gangue accumulation and occupies land resources.

[0006] The technical solution of this invention is: a coal gangue-based organic carbon soil conditioner, which is composed of the following raw materials in weight percentage: coal gangue; catalytic decomposition enzymes, at a ratio of 0.005%-0.5%, used to decompose large molecular carbon into small molecular carbon that is easily absorbed by plants; heavy metal resistant bacteria, at a ratio of 0.005%-0.5%, used to convert highly toxic heavy metals into low-toxicity heavy metals; sulfate or quicklime, at a ratio of 0.5%-2%, used to adjust soil pH; bio-based CMC cellulose, at a ratio of 0.3%-2%, used to slow-release nutrients and increase viscosity, which helps prevent segregation during pipeline transportation; and TWEEN-80 surfactant, at a ratio of 0.1%-1%, used to retain moisture and increase the activity of carbon fertilizer.

[0007] Furthermore, coal gangue is a mixture of microparticles and granules. By blending multiple particle sizes, it improves the physical structure of the soil and ensures soil permeability.

[0014] Furthermore, the detection component includes:

[0015] A detection frame is disposed on the cover, the cover having a rectangular through hole. The detection frame slides within the rectangular through hole and is located above the active roller group and the adjusting roller group, for detecting the height of coal gangue accumulated between the active roller group and the adjusting roller group.

[0017] A friction component is installed on the second power element, and the friction component is provided with a friction part, which frictionally engages with the cover.

[0018] A limiting component is provided on the detection frame to reduce the squeezing force of the detection frame on the coal gangue accumulated between the active roller group and the adjusting roller group;

[0020] Furthermore, the radius of the friction part is equal to the distance between the center of the friction element and the cover, and the radius of the remaining positions of the friction element is smaller than the distance between the center of the friction element and the cover.

[0021] Furthermore, the limiting component includes:

[0022] An extrusion strip is slidably connected inside the detection frame, and the extrusion strip extends out of the lower side of the detection frame, so that the extrusion strip contacts the coal gangue before the detection frame.

[0023] An elastic element is fixed to the extrusion strip near the rectangular through hole, and is used to provide support and reset force for the extrusion strip. The elastic element is slidably connected to the detection frame.

[0024] An elliptical piston is fixed to the elastic element, and a compression chamber is provided inside the detection frame. The elliptical piston slides in a sealed manner within the compression chamber.

[0025] Symmetrically distributed limiting blocks are slidably connected to the detection frame. A tension spring is fixed between the limiting blocks and the detection frame. The symmetrically distributed limiting blocks and the detection frame cooperate to form a limiting cavity. The limiting cavity is connected to the extrusion cavity. Two sets of symmetrical limiting grooves are provided on the cover near the rectangular through hole. The limiting blocks cooperate with the adjacent limiting grooves.

[0026] Furthermore, the transmission assembly includes:

[0027] A transmission cylinder is fixedly connected to the cover. A piston rod is slidably connected inside the transmission cylinder. The piston rod is fixedly connected to the detection frame. A sealing piston is slidably connected inside the transmission cylinder. A spring is fixedly connected between the sealing piston and the transmission cylinder.

[0033] Furthermore, the arc length of the friction part is less than the height of the telescopic member.

[0034] Furthermore, the spring force between the sealing piston and the transmission cylinder is greater than the centrifugal force on the weight.

[0035] Furthermore, the delay component includes:

[0036] A flow-limiting plate is fixed to the transmission cylinder and located in the transfer cavity. The flow-limiting plate is provided with multiple flow-limiting holes, some of which are equipped with one-way valves.

[0037] In summary, this application includes at least one of the following beneficial technical effects: This invention prepares a soil conditioner by mixing coal gangue with other substances, enabling large-scale utilization of accumulated coal gangue, increasing the utilization speed of coal gangue, and alleviating the land resource occupation problem caused by coal gangue accumulation.

[0038] By crushing coal gangue into a mixture of microparticles and granules, and then mixing it with other substances to prepare a soil conditioner, it can be transported via pipelines in a fluidized manner, reducing the cost of coal gangue transportation and improving transportation efficiency.

[0039] By changing the position of the weight, the amplitude generated by the eccentric block during rotation is altered, thus changing the feeding speed of the feed shell. In this way, the accumulated coal gangue is processed preferentially under a limited crushing speed, reducing the volume of accumulated coal gangue and minimizing the wear caused by coal gangue on the active roller group and the regulating roller group, thereby extending the service life of the active roller group and the regulating roller group.

[0040] By intermittently moving the detection frame upwards and then downwards, ensuring that the detection frame is always positioned above the coal gangue, the distance between the detection frame when it stops falling and its initial position is the thickness of the coal gangue accumulation. This allows us to determine the thickness of the coal gangue accumulated on the active roller group and the adjusting roller group.

[0041] When the extrusion bar comes into contact with the coal gangue, the transmission limit block limits the detection frame, preventing all the weight on the detection frame from being squeezed onto the accumulated coal gangue, thus reducing the wear caused by the coal gangue on the active roller group and the adjusting roller group.

[0042] By slowing down the reset speed of the heavy block through the delay component, the volume of coal gangue accumulated on the active roller group and the regulating roller group is reduced rapidly, thereby reducing the wear caused by coal gangue on the active roller group and the regulating roller group.

Detailed Implementation

[0053] To make the above-mentioned objects, features, and advantages of the present invention more apparent and understandable, specific embodiments of the present invention will be described in detail below with reference to the accompanying drawings. Many specific details are set forth in the following description to provide a thorough understanding of the present invention. However, the present invention can be practiced in many other ways different from those described herein, and those skilled in the art can make similar modifications without departing from the spirit of the present invention. Therefore, the present invention is not limited to the specific embodiments disclosed below.

[0054] A coal gangue-based organic carbon soil conditioner, comprising the following raw materials by weight percentage: coal gangue; catalytic decomposition enzymes, at a ratio of 0.005%-0.5%, used to decompose large molecular carbon into small molecular carbon that is easily absorbed by plants; heavy metal-resistant bacteria, at a ratio of 0.005%-0.5%, used to convert highly toxic heavy metals into less toxic heavy metals; sulfates or slaked lime, at a ratio of 0.5%-2%, used to adjust soil pH; bio-based CMC cellulose, at a ratio of 0.3%-2%, used to slow-release nutrients and increase viscosity, which helps prevent segregation during pipeline transportation; and TWEEN-80 surfactant, at a ratio of 0.1%-1%, used to retain moisture and increase the activity of carbon fertilizer.

[0055] Coal gangue is a mixture of microparticles and granules. By blending various particle sizes, it improves the physical structure of the soil and ensures its permeability.

[0056] The above-mentioned solution aims to address the problem that the utilization rate of coal gangue is lower than the production rate, leading to the accumulation of coal gangue and the occupation of land resources. The solution involves mixing coal gangue with other substances to prepare a soil conditioner, enabling large-scale utilization of accumulated coal gangue and alleviating the land resource occupation problem caused by coal gangue accumulation. Coal gangue particles can be broken down into small, round particles using crushers or sand making machines, facilitating fluidized pipeline transportation. Furthermore, by crushing coal gangue into a mixture of particle sizes, the soil structure is improved, restoring it to a loose, porous state with appropriate compaction and stability, which helps the soil retain moisture and nutrients while resisting weathering and erosion.

[0057] The preparation steps are as follows: S1: The coal gangue is crushed into a mixture of large and small particle sizes by a jaw crusher and a double-roll sand making machine in sequence; S2: Then, the catalytic decomposition enzyme, heavy metal resistant bacteria, sulfate or quicklime, bio-based CMC cellulose and TWEEN-80 surfactant are mixed in proportion, and the remaining part is supplemented by coal gangue microparticles and granules to form an organic carbon soil conditioner; S3: An appropriate amount of water and a carefully selected thickener are added to the organic carbon soil conditioner to prepare a fluid medium with high stability and that is not prone to segregation and sedimentation.

[0058] A fluidization apparatus for preparing a coal gangue-based organic carbon soil conditioner, based on the aforementioned coal gangue-based organic carbon soil conditioner, please refer to [link to relevant documentation]. Figures 1-4 The system includes: a mounting base 1; a cover 2, mounted on the mounting base 1, with a drive roller assembly 201 rotatably connected inside the cover 2 and a sliding roller assembly 202 rotatably connected inside the cover 2 and slidably connected to the mounting base 1, the drive roller assembly 201 and the sliding roller assembly 202 cooperating to crush coal gangue; and a feed shell 3, mounted on the mounting base 1, located above the cover 2, for feeding material into the cover 2, the feed shell 3 being fixedly connected to a first drive roller assembly. The first power element 301 is equipped with an eccentric block 302; a weight 4 is installed inside the eccentric block 302, and a sliding cavity 303 is opened inside the eccentric block 302. The weight 4 slides in a sealed manner within the sliding cavity 303. A flow control channel 401 communicating with the sliding cavity 303 is opened inside the eccentric block 302; a detection component is set at the position of the cover 2 near the feed shell 3, and is used to detect the volume of coal gangue accumulated between the active roller group 201 and the regulating roller group 202.

[0059] Both the active roller group 201 and the adjusting roller group 202 consist of a crushing roller and two rectangular seats rotatably connected to the crushing roller. The crushing roller on the active roller group 201 is rotatably connected to the cover 2, and the rectangular seats on the active roller group 201 are connected to the mounting base 1 by bolts. The crushing roller on the adjusting roller group 202 is slidably and rotatably connected to the cover 2, and the rectangular seats on the adjusting roller group 202 are slidably connected to the mounting base 1.

[0060] The above solution aims to address the problem that uneven particle size distribution of coal gangue during the crushing of coal gangue in existing double-roll crushers easily leads to material accumulation and severe wear of the double-roll crusher. The flow control channel 401 can store transmission fluid, which is then used for power transmission. A feed shell 203 can be installed above the cover 2 to guide the coal gangue from the feed shell 3 into the cover 2, reducing the probability of coal gangue spilling out of the cover 2. The feed shell 3 and the mounting base 1 can be connected by springs or other elastic materials to reduce the impact of vibration of the feed shell 3 on the mounting base 1. The first power element 301 can be a motor or hydraulic motor, or other components with the same function.

[0061] The position of the weight 4 is changed by the flow of the transmission fluid in the flow control channel 401, thereby changing the position of the center of gravity of the eccentric block 302. When coal gangue accumulates on the active roller group 201 and the adjusting roller group 202, the detection component detects the accumulation and controls the weight 4 to move closer to the rotation axis of the eccentric block 302 by controlling the transmission fluid. This reduces the distance between the center of gravity of the eccentric block 302 and the weight 4 and the rotation axis of the eccentric block 302, that is, reduces the eccentricity of the eccentric block 302 and the weight 4. When the eccentric block 302 and the weight block 4 rotate together, the centrifugal force they experience decreases, which in turn reduces the amplitude of the vibration generated by the eccentric block 302 during rotation. This reduces the volume of coal gangue that the feed shell 3 feeds into the cover 2 per unit time. Thus, under a limited crushing speed, the coal gangue accumulated on the active roller group 201 and the adjusting roller group 202 is processed first, reducing the volume of coal gangue accumulated on the active roller group 201 and the adjusting roller group 202, and reducing the wear of the active roller group 201 and the adjusting roller group 202 on the coal gangue during rotation.

[0062] Please see Figure 5 The detection assembly includes: a detection frame 5, disposed on the cover 2, the cover 2 having a rectangular through hole 501, the detection frame 5 sliding within the rectangular through hole 501, and the detection frame 5 positioned above the active roller group 201 and the adjusting roller group 202, used to detect the height of coal gangue accumulated between the active roller group 201 and the adjusting roller group 202; a second power element 6, mounted on the detection frame 5 and located outside the cover 2; a friction element 7, mounted on the second power element 6, the friction element 7 having a friction part 701, the friction part 701 frictionally engaging with the cover 2; a limiting assembly, disposed on the detection frame 5, used to reduce the squeezing force of the detection frame 5 on the coal gangue accumulated between the active roller group 201 and the adjusting roller group 202; and a transmission assembly, disposed on the detection frame 5, used to adjust the position of the weight 4 based on the detection result of the detection frame 5.

[0063] The radius of the friction part 701 is equal to the distance between the center of the friction member 7 and the cover 2, and the radius of the other parts of the friction member 7 is smaller than the distance between the center of the friction member 7 and the cover 2.

[0064] In the above scheme, the purpose is to detect the accumulation of coal gangue between the active roller group 201 and the adjusting roller group 202 by the position of the detection frame 5; the cross-section of the detection frame 5 is approximately "U"-shaped, and the width of the "U" shape on the detection frame 5 is greater than the gap between the active roller group 201 and the adjusting roller group 202, so as to reduce the impact on the falling path of the coal gangue; the two ends of the detection frame 5 can be fixed with symmetrically distributed baffles 502, which are used to block the adjacent rectangular through holes 501 to prevent the coal gangue in the cover 2 from entering the rectangular through holes 501 and obstructing the movement of the detection frame 5; the second power element 6 can be a component with the same function, such as an electric motor or a hydraulic motor; the friction element 7 can be made of a material with a high coefficient of friction, such as hard rubber.

[0065] The second power element 6 drives the friction element 7 to rotate, causing the friction part 701 to intermittently contact the cover 2. When they are in contact, as the friction element 7 rotates, the friction between the friction part 701 and the cover 2 drives the detection frame 5 to move upward a certain distance until the friction part 701 loses contact with the cover 2. Then, the detection frame 5 falls under its own gravity until it resets or comes into contact with the accumulated coal gangue. At this point, the detection frame 5 stops moving downward. Then, the above steps are repeated to make the detection frame 5 move upward and fall intermittently, keeping the detection frame 5 always above the coal gangue. Thus, the distance between the detection frame 5 when it stops falling and the initial distance is the thickness of the accumulated coal gangue.

[0066] Please see Figure 5 and Figure 6 The limiting components include: an extrusion strip 8, slidably connected to the detection frame 5, the extrusion strip 8 protruding from the lower side of the detection frame 5, so that the extrusion strip 8 contacts the coal gangue before the detection frame 5; an elastic element 9, fixedly connected to the extrusion strip 8 near the rectangular through hole 501, used to provide support and reset force for the extrusion strip 8, the elastic element 9 is slidably connected to the detection frame 5; an elliptical piston 10, fixedly connected to the elastic element 9, the detection frame 5 is provided with an extrusion chamber 101, the elliptical piston 10 slides in a sealed manner within the extrusion chamber 101; symmetrically distributed limiting blocks 11, sealed and slidably connected to the detection frame 5, a tension spring is fixedly connected between the limiting blocks 11 and the detection frame 5, the symmetrically distributed limiting blocks 11 and the detection frame 5 cooperate to form a limiting cavity 111, the limiting cavity 111 communicates with the extrusion chamber 101, and two sets of symmetrical limiting grooves 112 are provided on the cover 2 near the rectangular through hole 501, the limiting blocks 11 cooperate with the adjacent limiting grooves 112 for limiting.

[0067] In the above scheme, the aim is to reduce the squeezing force of the detection frame 5 on the accumulated coal gangue, and to prevent the detection frame 5 from squeezing the coal gangue when it comes into contact with it, which would increase the squeezing force of the coal gangue on the active roller group 201 and the adjusting roller group 202, thus increasing the wear on the active roller group 201 and the adjusting roller group 202. The squeezing strips 8 can be two symmetrically distributed, and the distances between the active roller group 201 and the adjusting roller group 202 and the adjacent squeezing strips 8 are equal, which improves the sensitivity of the movement of the squeezing strip 8 transmission limit block 11. The number of subsequent elastic elements 9, elliptical pistons 10, limit blocks 11, and limit grooves 112 changes synchronously. The squeezing strips 8 can correspond to two symmetrically distributed elastic elements 9, and one side of the elastic element 9 corresponds to the adjacent elliptical piston 11. 0 is fixed, and the elastic element 9 on the other side simply provides the power for the adjacent extrusion strip 8 to reset; the elastic element 9 can be made of plastic or metal elastic material. Initially, the elastic element 9 is in a bent state. The minimum distance between the fixed position of the elastic element 9 and the end of the adjacent extrusion strip 8 is less than the length of the elastic element 9 when it is unfolded. When the extrusion strip 8 moves upward relative to the detection frame 5, it squeezes the elastic element 9 to a straight state. During this process, the end of the elastic element 9 moves along the detection frame 5; the two symmetrically distributed limiting blocks 11 have inclined surfaces facing upward on opposite sides. When the limiting block 11 is engaged with the adjacent limiting groove 112, it can only move upward in one direction. Without changing the above scheme, the limiting block 11 and the adjacent limiting groove 112 can be replaced with a structure similar to a ratchet and pawl.

[0068] As the detection frame 5 descends, it causes the extrusion strip 8 to move downwards. The distance between the extrusion strip 8 and the accumulated coal gangue gradually decreases until the extrusion strip 8 contacts the coal gangue, at which point it stops moving. The detection frame 5 then continues to descend, and the extrusion strip 8 moves upwards relative to the detection frame 5 and enters the frame. During this process, the extrusion strip 8 drives the elliptical piston 10 to move via the elastic element 9. The elliptical piston 10 extrudes the transmission fluid in the adjacent extrusion chamber 101 into the limiting chamber 111. The transmission fluid in the limiting chamber 111 pushes the symmetrically distributed limiting blocks 11 to move backwards and stretches the adjacent tension springs. The limiting blocks 11 then enter the adjacent limiting grooves 112. The detection frame 5 is positioned so that its position reflects the height of the coal gangue accumulated between the active roller group 201 and the adjusting roller group 202. When the detection frame 5 moves upward again, the limiting block 11 is squeezed by the adjacent limiting groove 112 and retracts into the limiting cavity 111 to reset. At the same time, the squeezing strip 8 is reset relative to the detection frame 5 under the action of the elastic element 9. In this way, the squeezing strip 8 drives the limiting block 11 to move and limits the detection frame 5, preventing all the weight on the detection frame 5 from being squeezed onto the coal gangue accumulated between the active roller group 201 and the adjusting roller group 202, thus reducing the wear caused by the coal gangue on the active roller group 201 and the adjusting roller group 202.

[0069] Please see Figure 1 , Figure 3 , Figure 4 , Figure 7 and Figure 8 The transmission assembly includes: a transmission cylinder 12, fixedly connected to the housing 2; a piston rod 13 is slidably connected inside the transmission cylinder 12 and fixedly connected to the detection frame 5; a sealing piston 14 is slidably connected inside the transmission cylinder 12 and a spring is fixedly connected between the sealing piston 14 and the transmission cylinder 12; the transmission cylinder 12, piston rod 13, and sealing piston 14 cooperate to form a transmission cavity 141; a telescopic member 15, fixedly connected to the sealing piston 14 and communicating with the transmission cavity 141; a transfer cavity 121 is opened inside the transmission cylinder 12 and communicates with the telescopic member 15; a first connecting member 161 is fixedly connected to the transmission cylinder 12 and communicates with the transfer cavity 121; the first connecting member 161 communicates with the transfer cavity 121. The flow control channel 401 is connected, and the eccentric block 302 is rotatably connected to the first connecting member 161; the sealing plate 16 is slidably connected to the transmission cylinder 12, and the first connecting member 161 and the sealing plate 16 are sealed together; the hydraulic telescopic rod 17 is fixed to the transmission cylinder 12, and the telescopic end of the hydraulic telescopic rod 17 is fixed to the sealing plate 16; the arc-shaped liquid bladder 18 is fixed to the friction member 7, and the friction member 7 has a connecting flow channel 181 that communicates with the arc-shaped liquid bladder 18. The friction member 7 is rotatably connected to a second connecting member 182 that communicates with the connecting flow channel 181, and the second connecting member 182 communicates with the hydraulic telescopic rod 17; the delay component is set in the transfer cavity 121 to delay the reset of the weight 4.

[0070] The arc length of the friction part 701 is less than the height of the telescopic part 15.

[0071] The spring force between the sealed piston 14 and the transmission cylinder 12 is greater than the centrifugal force on the weight 4.

[0072] In the above scheme, the movement of the weight 4 is controlled by the transmission fluid based on the coal gangue accumulation detected by the detection component. The arc-shaped liquid bladder 18 can be made of elastic material, or the hydraulic telescopic rod 17 can be a spring telescopic rod, used to drive the sealing plate 16 to reset. The position where the second connecting member 182 is rotatably connected to the friction member 7 can be made of rigid material to prevent the second connecting member 182 from getting tangled under the action of the friction member 7. The position where the second connecting member 182 is rotatably connected to the friction member 7 can be fixed to the detection frame 5 by a bracket to improve the stability of the second connecting member 182 when the friction member 7 rotates. The position where the first connecting member 161 is rotatably connected to the eccentric block 302 can be made of rigid material. The position where the first connecting member 161 is rotatably connected to the eccentric block 302 can be fixed to the lower side of the feed shell 3 by a bracket to improve the stability of the first connecting member 161 when the eccentric block 302 rotates. The telescopic member 15 can be a bellows or other parts with a contraction function to make the telescopic member 15 move with the sealing piston 14.

[0073] As the detection frame 5 moves upward, it drives the piston rod 13 upward as well. The piston rod 13, through the transmission fluid in the transmission chamber 141, squeezes the sealing piston 14 upward and compresses the telescopic member 15 and the spring adjacent to the upper side of the sealing piston 14. When the detection frame 5 falls to contact the coal gangue, the position of the detection frame 5 changes relative to its initial position. Similarly, the position of the piston rod 13 moves upward relative to its initial position. When the arc-shaped liquid bladder 18 contacts the cover 2, the cover 2 squeezes the arc-shaped liquid bladder 18, causing the transmission fluid inside the arc-shaped liquid bladder 18 to pass through... The flow through the connecting channel 181 and the second connecting member 182 flows into the hydraulic telescopic rod 17. The telescopic end of the hydraulic telescopic rod 17 extends and drives the sealing plate 16 to move. The sealing plate 16 releases the blockage of the first connecting member 161. At this time, the sealing piston 14 moves down and resets under the action of its adjacent spring, and squeezes the transmission fluid in the transmission chamber 141, so that the transmission fluid enters the first connecting member 161 through the telescopic member 15 and the transfer chamber 121. The transmission fluid in the first connecting member 161 drives the weight 4 to move, thus realizing the adjustment of the position of the weight 4.

[0074] As the friction element 7 rotates, the arc-shaped liquid bladder 18 loses contact with the cover 2. After that, the arc-shaped liquid bladder 18 resets and retracts through the telescopic end of the transmission hydraulic telescopic rod 17, so that the sealing plate 16 re-seals the first connecting piece 161, thus completing the adjustment of the position of the weight 4.

[0075] Please see Figure 8 and Figure 9 The delay component includes: a flow limiting plate 19, which is fixed to the transmission cylinder 12 and located in the transfer chamber 121. The flow limiting plate 19 is provided with a plurality of flow limiting holes 191, and a one-way valve 192 is installed in some of the flow limiting holes 191.

[0076] In the above scheme, the aim is to delay the change in the feed flow rate of the feed shell 3 as the volume of coal gangue accumulated between the active roller group 201 and the regulating roller group 202 gradually decreases, so that the accumulated coal gangue is quickly crushed and the wear caused by the coal gangue on the active roller group 201 and the regulating roller group 202 is reduced. The number of flow-limiting holes 191 can be two or more. Here, two flow-limiting holes 191 are selected. One of the flow-limiting holes 191 is equipped with a one-way valve 192. The one-way valve 192 flows from bottom to top. When the position of the weight 4 is adjusted by the transmission fluid, the transmission fluid flows through the two flow-limiting holes 191. When the weight 4 is reset, the transmission fluid flows through the two flow-limiting holes 191. At this time, the transmission fluid flows only through a single flow-limiting hole 191, so that under the condition of the same single connection time (i.e. the time when the sealing plate 16 is released and the first connecting member 161 is resealed), the volume of transmission fluid flowing in a single time is different. This allows the weight block 4 to be quickly adjusted when the coal gangue is piled up. As the volume of the piled coal gangue gradually decreases, the weight block 4 is slowly reset, so that the feeding speed of the feed shell 3 is kept less than the crushing speed of the device. This causes the volume of coal gangue piled between the active roller group 201 and the adjusting roller group 202 to decrease rapidly, shortening the time for the coal gangue to wear on the active roller group 201 and the adjusting roller group 202.

[0077] The specific operation of this device for crushing coal gangue is as follows: First, the detection component is activated, causing the detection frame 5 to intermittently move upward and then fall. Workers continuously feed the coal gangue processed by the jaw crusher into the feed housing 3 using a loader or conveyor belt, ensuring a stable flow of coal gangue into the housing 2. The coal gangue is crushed by the counter-rotating motion of the active roller group 201 and the adjusting roller group 202. When the coal gangue particles falling between the active roller group 201 and the adjusting roller group 202 are too large, the device will further crush the coal gangue. The reduced speed causes coal gangue to accumulate between the active roller group 201 and the adjusting roller group 202. The detection component detects the volume of the accumulated coal gangue and adjusts the position of the weight block 4 through the transmission component, causing the center of gravity of the eccentric block 302 and the weight block 4 to shift, reducing the amplitude of the feed shell 3 and reducing the amount of material fed by the feed shell 3 per unit time. In this way, the accumulated coal gangue is crushed preferentially under the limited crushing speed, reducing the wear on the device and eliminating the need for active shutdown, thus improving production efficiency.

[0078] Although embodiments of the invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the invention.
