Description

Technical Field

[0001] This utility model relates to the field of coal sample preparation technology, specifically to an intelligent integrated crushing and splitting device. Background Technology

[0002] Conveyor belt slitting equipment is widely used in coal sample preparation technology. However, due to the continuous nature of conveyor belt transport, operators often find it difficult to continuously and precisely adjust the slitting ratio when preparing coal samples with different required quantities. Furthermore, as the primary transport medium in conveyor belt slitting equipment, the length, width, and drive system configuration of the conveyor belt mean that this equipment occupies a significant amount of production space, posing challenges to the layout and planning of the production site, and causing considerable inconvenience to the installation, commissioning, and maintenance of the equipment. Utility Model Content

[0003] This utility model is based on the inventor's discovery and understanding of the following facts and problems:

[0004] Conveyor belt sample reduction equipment utilizes a conveyor belt as the transport medium for coal samples, achieving continuous and uniform transport and reduction of coal samples, greatly improving the efficiency and automation level of coal sample preparation. However, despite the many advantages exhibited by conveyor belt sample reduction equipment in the coal sample preparation process, some problems that cannot be ignored have also been exposed in practical applications.

[0005] While the continuous transport of coal samples via conveyor belts ensures uninterrupted delivery, it presents challenges for operators in adjusting the reduction ratio when preparing samples of varying quantities. Due to the uninterrupted nature of the conveyor belt, operators find it difficult to achieve continuous and precise adjustments to the reduction ratio during sample transport. This often necessitates manual adjustment of equipment parameters or replacement of different slitting devices, increasing operational complexity and labor intensity, and potentially impacting the accuracy and efficiency of sample preparation. This problem is particularly pronounced in production scenarios requiring frequent adjustments to the reduction ratio.

[0006] Furthermore, as the primary transmission medium in conveyor belt-type slitting equipment, the physical characteristics of the conveyor belt significantly influence the overall size and structure of the equipment. The length and width of the conveyor belt directly determine the equipment's footprint and transmission capacity, while the configuration of the drive system further affects the overall size and weight of the equipment. These factors combined mean that conveyor belt-type slitting equipment often occupies a significant amount of space on the production site, posing considerable challenges to the layout and planning of the production area. To meet the equipment's installation requirements, sufficient space often needs to be reserved on the production site, which not only increases production costs but may also affect the layout and operational efficiency of other equipment.

[0007] Therefore, embodiments of this utility model propose an intelligent crushing and splitting integrated device, which can achieve stepless adjustment of the splitting ratio, realize integrated structural design, help reduce size, and reduce the equipment's dependence on site space.

[0008] An embodiment of this utility model provides an intelligent crushing and splitting integrated device, comprising a crushing component, a transport component, and a splitting component.

[0015] In some embodiments, the crushing assembly includes a crushing chamber and a hammer, the hammer being rotatably disposed within the crushing chamber, and the feed inlet being disposed on the side wall of the crushing chamber along the axial direction of the hammer.

Detailed Implementation

[0031] The embodiments of the present invention are described in detail below, examples of which are illustrated in the accompanying drawings. The embodiments described below with reference to the accompanying drawings are exemplary and intended to explain the present invention, and should not be construed as limiting the present invention.

[0032] like Figures 1 to 6As shown, an embodiment of the present invention provides an intelligent crushing and dividing integrated device, which includes a crushing component 10, a transport component 20, and a dividing component 30. The crushing component 10 has an inlet 11 and is used to crush materials. The transport component 20 is used to transport the crushed materials from the crushing component 10 to the dividing component 30. The dividing component 30 includes a cavity 31, a guide plate 32, and a driver 33. The cavity 31 includes a feeding cavity 311, a sample retention cavity 312, and a sample rejection cavity 313. The feeding cavity 311 is located below the transport component 20. The guide plate 32 is rotatably connected to the output end of the driver 33. The guide plate 32 has a first position and a second position relative to the cavity 31. When the guide plate 32 is in the first position, the guide plate 32 disconnects the feeding cavity. The feed chamber 311 is connected to the sample rejection chamber 313, and the feed chamber 311 is connected to the sample retention chamber 312. When the guide plate 32 is in the second position, the guide plate 32 disconnects the connection between the feed chamber 311 and the sample retention chamber 312, and connects the feed chamber 311 to the sample rejection chamber 313. The guide plate 32 includes a main plate 324, a first side plate 325, and a second side plate 326. Both the first side plate 325 and the second side plate 326 are connected to the main plate 324. The first side plate 325 and the second side plate 326 are positioned opposite each other on both sides of the main plate 324. The first side plate 325, the main plate 324, and the second side plate 326 can form a U-shaped structure, which not only enhances the overall strength and stability of the guide plate 32, but also effectively limits the flow range of the material, preventing side leakage and overflow of the material during the reduction process. The shape and size of the first side plate 325 and the second side plate 326 match the main plate 324 to ensure that they can fit tightly together to form a smooth material channel. The first side plate 325 and the second side plate 326 can be connected to the main plate 324 by welding, bolting, or snap-fitting. The sample retention chamber 312 and the sample disposal chamber 313 are arranged alternately, and both the sample retention chamber 312 and the sample disposal chamber 313 extend vertically, which can effectively reduce the air resistance when the coal sample falls.

[0033] Specifically, when the coal sample falls freely from a high place to a low place, its falling direction perfectly matches the extension direction of the sample retention chamber 312 or the sample disposal chamber 313, forming a near-straight falling trajectory. This reduces the frictional resistance between the coal sample and the air during the fall. Air resistance is generally greatest when perpendicular to the direction of motion and least when aligned with it. Therefore, the vertically extending chamber 31 design allows the coal sample to fall more smoothly and efficiently, avoiding slowing down or trajectory deviation caused by excessive air resistance.

[0034] Specifically, the crushing component 10, the conveying component 20, and the reducing component 30 are arranged vertically from top to bottom to achieve integration of the overall structure and reduce space occupation. The driver 33 drives the guide plate 32 to rotate within the cavity 31. When the guide plate 32 is in the first position, it can block the space between the feed cavity 311 and the sample disposal cavity 313, allowing the material crushed by the crushing component 10 to flow through the conveying component 20 and the feed cavity 311 into the sample retention cavity 312.

[0035] When the guide plate 32 is in the second position, it can block the space between the feed chamber 311 and the sample retention chamber 312, connecting the feed chamber 311 and the waste sample chamber 313. This allows the material crushed by the crushing component 10 to flow through the transport component 20 and the feed chamber 311 into the waste sample chamber 313. The sample retention chamber 312 can be connected to a sample retention container to collect materials that need to be retained, and the waste sample chamber 313 can be connected to a waste sample container to collect discarded materials.

[0036] In other words, when the driver 33 drives the guide plate 32 to rotate from the first position to the second position, the guide plate 32 can rotate relative to the cavity 31 until the connection between the feed cavity 311 and the sample retention cavity 312 is broken, so that the feed cavity 311 is connected to the sample rejection cavity 313, so that the material crushed by the crushing component 10 can flow through the transport component 20 and the feed cavity 311 into the sample rejection cavity 313, thus realizing the automatic rejection of unwanted materials.

[0037] Conversely, when the driver 33 drives the guide plate 32 to rotate from the second position to the first position, the guide plate 32 can rotate relative to the cavity 31 until the connection between the feed cavity 311 and the discard cavity 313 is broken, so that the feed cavity 311 is connected to the retention cavity 312, so that the material crushed by the crushing component 10 can flow through the transport component 20 and the feed cavity 311 into the retention cavity 312 for subsequent analysis or testing.

[0038] In summary, the intelligent crushing and reducing integrated device provided by this utility model can achieve stepless adjustment of the reducing ratio by driving the guide plate 32 to rotate through the driver 33, thereby solving the problem of the inability to continuously adjust the reducing ratio and realizing integrated sample preparation and reducing. Furthermore, the integrated setting of the crushing component 10, the transport component 20 and the reducing component 30 can also reduce the size and reduce the dependence on site space.

[0039] like Figure 2 and Figure 3As shown, in some embodiments, the splitting assembly 30 further includes a transmission rod 34 and two limiters 35. The guide plate 32 has a rotating shaft 321. One end of the transmission rod 34 is connected to the output end of the driver 33, and the other end of the transmission rod 34 is connected to the rotating shaft 321 of the guide plate 32. The limiters 35 are used to abut against the transmission rod 34. The two limiters 35 are respectively located at the first position and the second position of the guide plate 32, thereby limiting the rotation range of the guide plate 32.

[0040] That is, one of the two limiters 35 is located at the first position of the guide plate 32, and the other of the two limiters 35 is located at the second position of the guide plate 32. When the guide plate 32 rotates to the first position or the second position, the transmission rod 34 will abut against the corresponding limiter 35, thereby effectively preventing the guide plate 32 from continuing to rotate, thus ensuring that the guide plate 32 can accurately stop at the predetermined position.

[0041] Furthermore, the transmission rod 34 includes a first arm 341, a second arm 342, and a positioning post 343. A clamping cavity 344 and a gap groove 345 are provided between the first arm 341 and the second arm 342. The rotating shaft 321 of the guide plate 32 is located in the clamping cavity 344. The gap groove 345 extends along the length of the transmission rod 34 and communicates with the clamping cavity 344. The first arm 341 and the second arm 342 are both provided with positioning holes 347. The positioning post 343 is detachably inserted into the positioning hole 347 to connect the first arm 341 and the second arm 342, so that the first arm 341 and the second arm 342 clamp the rotating shaft 321 of the guide plate 32, thereby fixing the rotating shaft 321 of the guide plate 32 to the transmission rod 34.

[0042] Specifically, the transmission rod 34 has a main rod 346, and the first arm 341 and the second arm 342 both extend from the main rod 346 toward the distal end. A clamping cavity 344 is located at the connection between the main rod 346, the first arm 341, and the second arm 342; that is, both the first arm 341 and the second arm 342 extend from the clamping cavity 344 toward the distal end. A gap groove 345 extends from the distal end of the transmission rod 34 along the length of the transmission rod 34 toward the clamping cavity 344 and communicates with the clamping cavity 344, making the clamping cavity 344 open and providing elasticity between the first arm 341 and the second arm 342, facilitating the clamping and installation of the guide plate 32.

[0043] Furthermore, both the first arm 341 and the second arm 342 are provided with positioning holes 347, which can maintain a stable shape when the transmission rod 34 is under force, avoiding deformation or twisting. The positioning post 343 plays a key role in connecting the first arm 341 and the second arm 342. It is detachably inserted into the positioning hole 347, tightly connecting the first arm 341 and the second arm 342 together to form a stable integral structure. This not only ensures a stable and reliable connection between the first arm 341 and the second arm 342, but also allows for convenient disassembly and replacement as needed.

[0044] In this embodiment, the length of the first arm 341 is less than the length of the second arm 342, and the cross-sectional area of ​​the second arm 342 gradually decreases from the positioning hole 347 towards the distal end. This not only optimizes material utilization and reduces overall weight, but also significantly enhances the stability and load-bearing capacity of the structure. Furthermore, reducing the cross-sectional area at the distal end effectively reduces bending deformation caused by stress, thereby improving the overall structural rigidity. Simultaneously, this design allows for more economical and efficient material use while ensuring structural strength, reducing production costs.

[0045] In this embodiment, the material reduction assembly 30 further includes a fixing post 37. A fixing hole 348 is provided on the side wall of the clamping cavity 344. One end of the fixing post 37 passes through the fixing hole 348 and connects to the rotating shaft 321 of the guide plate 32 to fix the rotating shaft 321 and the transmission rod 34. The connection between the fixing post 37 and the rotating shaft 321 of the guide plate 32 after passing through the fixing hole 348 not only enhances the connection strength between the transmission rod 34 and the guide plate 32 but also ensures the synchronization and stability of the two during rotation. Furthermore, due to the presence of the fixing post 37, even when the guide plate 32 is operating at high speed or subjected to large external forces, the connection between the transmission rod 34 and the guide plate 32 will not loosen or detach, thereby ensuring the normal operation of the equipment and the accuracy of material reduction.

[0046] Furthermore, the rotating shaft 321 has a first plane 322 and a second plane 323 disposed opposite to each other, and the first plane 322 and the second plane 323 are disposed on the outer periphery of the rotating shaft 321. The clamping cavity 344 has an abutment portion that is adapted to the first plane 322 and the second plane 323, thereby making the rotating shaft 321 more firmly fixed in the clamping cavity 344, and facilitating the transmission rod 34 to drive the rotating shaft 321 to rotate.

[0047] Furthermore, the rotating shaft 321 is provided with a through hole, and the fixing post 37 is inserted into the through hole to fix the rotating shaft 321 and the transmission rod 34, so as to prevent the transmission rod 34 and the rotating shaft 321 from offset rotation.

[0048] In this embodiment, the actuator 33 includes a pneumatic cylinder or a hydraulic cylinder. Pneumatic cylinders offer advantages such as simple structure, rapid action, ease of control, and low maintenance costs. They utilize compressed air as the working medium, driving the piston rod to reciprocate linearly through the expansion and contraction of the compressed air, thereby rotating the transmission rod 34 and the guide plate 32. Hydraulic cylinders, on the other hand, use an oil pump to deliver hydraulic oil into the working chamber, using the oil pressure to drive the piston in linear motion, thus rotating the transmission rod 34 and the guide plate 32.

[0049] It should be noted that the choice between pneumatic cylinders and hydraulic cylinders depends on the specific application scenario and user needs. For example, pneumatic cylinders may be more suitable for situations requiring rapid response and frequent adjustments to material flow; while hydraulic cylinders may be more advantageous for situations requiring larger loads or smoother movement.

[0050] In some embodiments, the limiter 35 includes a push rod 351 and a rubber head 352. The push rod 351 is movably disposed on the cavity 31, and the rubber head 352 is disposed on the push rod 351. The rubber head 352 is used to abut against the transmission rod 34. When the transmission rod 34 moves under the action of the driver 33, the rubber head 352 abuts against the transmission rod 34 at appropriate times, thereby limiting its range of motion. This limiting method is not only simple and effective, but also reduces the noise and vibration generated by the transmission rod 34 during movement, improving the overall stability and reliability of the equipment.

[0051] Furthermore, the limit switch 35 is designed with ease of maintenance and replacement in mind. Both the push rod 351 and the rubber head 352 can be easily disassembled and replaced. When they wear out or become damaged during use, the user does not need to replace the entire limit switch 35; only the damaged parts need to be replaced. This design not only reduces equipment maintenance costs but also improves user convenience.

[0052] Furthermore, the limiter 35 also includes a drive element 353. The push rod 351 is connected to the output end of the drive element 353. The drive element 353 can be a cylinder or a hydraulic cylinder, thereby adjusting the position of the glue head 352 to achieve adjustment of different positions of the guide plate 32. That is, the drive element 353 can adjust the position of the glue head 352 through the push rod 351, thereby changing the rotation angle of the guide plate 32, and thus changing the first position and the second position of the guide plate 32 to adapt to the reduction requirements of different materials.

[0053] Furthermore, the split assembly 30 also includes a mounting base 38, which has a bearing 381 inside. The rotating shaft 321 passes through the bearing 381, and the mounting base 38 is used to fix it to the cavity 31.

[0054] In some embodiments, there is a certain gap between the sample retention chamber 312 and the sample rejection chamber 313, and the gap distance is 20mm to 50mm.

[0055] like Figure 1 and Figure 4 As shown, in some embodiments, the crushing assembly 10 includes a crushing chamber 12 and a hammer 13. The hammer 13 is rotatably disposed within the crushing chamber 12, and the feed inlet 11 is disposed on the side wall of the crushing chamber 12 along the axial direction of the hammer 13. This effectively prevents the hammer 13 from carrying material out of the crushing chamber 12 during rotation, thereby reducing the risk of material blockage. This not only improves the continuity and stability of the crushing process but also ensures the long-term reliable operation of the equipment. It should be noted that the crushing assembly 10 also includes drive components such as a motor or electric motor, which will not be described in detail here.

[0056] like Figure 1 , Figure 5 , Figure 6 and Figure 7 As shown, in some embodiments, the transport assembly 20 includes a frame 21, a transport belt 22, side baffles 23, and a shaping scraper 25. The transport belt 22 is rotatably mounted on the frame 21 and has a transport trough 221. Two side baffles 23 are provided, which are arranged opposite each other on the frame 21 along the width direction of the transport belt 22. At least a portion of the side baffles 23 are located within the transport trough 221. The shaping scraper 25 is mounted on the frame and positioned above the transport belt 21. This ensures that the coal sample has a fixed width and height after being transported by the transport belt 21, which helps to accurately control the amount of coal sample transported and ensure the accuracy of sample reduction.

[0057] Specifically, the frame 21 has an upper top plate 211, and the side baffles 23 are disposed between the upper top plate 211 and the conveyor belt 22. The two side baffles 23 are disposed opposite to each other on the frame 21 along the width direction of the conveyor belt 22, and at least part of the side baffles 23 are located within the conveyor trough 221, thereby effectively preventing material leakage and overflow along the side of the conveyor belt during transportation, and ensuring that the coal sample can be accurately delivered to the reducing assembly.

[0058] The shaping scraper 25 can shape and flatten the coal sample during transport, and combined with the limiting effect of the side baffle 23 on the coal sample, the coal sample has a uniform width and height on the conveyor belt, which helps to improve the accuracy and stability of the reduction.

[0059] Furthermore, the conveyor belt 22 includes a strip-shaped bottom plate 222 and two side strips 223. The strip-shaped bottom plate 222 and the side strips 223 define the conveyor trough 221. The two side strips 223 are disposed opposite to each other on both sides of the strip-shaped bottom plate 222 in the width direction. The side strips 223 are disposed in a one-to-one correspondence with the side baffles 23, and the side strips 223 are disposed on the outside of the side baffles 23.

[0060] In the width direction of the conveyor belt 22, the side strip 223 is attached to the side baffle 23. In the height direction of the conveyor belt 22, there is a gap between the side baffle 23 and the strip-shaped bottom plate 222, and the height of the side strip 223 is greater than the gap to seal it, thereby preventing coal samples from overflowing from the side of the conveyor belt. It should be noted that the position of the coal sample on the conveyor belt is considered the inner side, and the position away from the coal sample is considered the outer side.

[0061] Furthermore, in some embodiments, the strip base plate 222 may be integrally formed with the side strip 223, or it may be separately formed; details will not be elaborated here. In this embodiment, the strip base plate 222 and the side strip 223 are integrally formed.

[0062] Furthermore, the transport assembly 20 also includes two guide plates 26, which are disposed opposite to each other at the ends of the frame 21 along the width direction of the transport belt 22, thereby guiding the coal sample from the direction of falling from the transport belt, preventing the coal sample from flowing to the sides of the frame, and ensuring that the coal sample flows completely into the reducing assembly.

[0063] In some embodiments, the frame 21 is provided with a limiting post 212, and the shaping scraper 25 is provided with a moving groove 251. The moving groove 251 is sleeved on the positioning post 343, and the shaping scraper 25 is movable relative to the frame 21. The moving groove 251 is designed as an oblong groove. That is to say, the user can easily adjust the position and angle of the shaping scraper 25 according to the properties of the material and the required conveying speed to achieve the best shaping effect. This design not only improves the accuracy and stability of material conveying, but also allows the shaping scraper 25 to be flexibly adjusted according to different material characteristics and conveying requirements, thereby meeting more diverse application scenario requirements.

[0064] In some embodiments, the transport component 20 includes a flow guide 27 disposed below the transport belt 22, the cross-sectional area of ​​which gradually decreases vertically from top to bottom. That is, the flow guide 27 has a funnel-like shape, effectively guiding and concentrating the material. When material pours down from above the transport belt 22, the flow guide 27 can quickly capture and guide this material, allowing it to flow smoothly along a predetermined path, preventing scattering and accumulation of material during transport.

[0065] Furthermore, in the practical application of the intelligent crushing and splitting integrated device provided by this utility model, it is first necessary to obtain the basic physical parameters of the coal sample, including the weight m of the coal sample, the width w and height h of the coal flow after rectification by the shaping scraper 25 of the transport component 20, and the transmission speed v of the transport belt 22 of the transport component 20. Meanwhile, we assume that the density ρ of the coal sample is a known constant. Based on these key parameters, the required transmission time t of the coal sample on the transport belt 22 can be accurately calculated using the following formula:

[0067] Next, if the user needs to adjust the reduction ratio to a specific 1 / 60, then a finer division can be made based on the previously calculated transmission time t. Specifically, the transmission time t of the coal sample on the conveyor belt 22 can be divided into 60 equal parts, with each part corresponding to one subsample. Thus, the total sampling time is t / 60, and the total time that the guide plate 32 spends at the waste disposal chamber 313 to collect or remove the coal sample is also t / 60. It is worth noting that this operation not only meets the reduction ratio requirement but also ensures the uniformity and representativeness of each subsample.

[0068] Furthermore, according to relevant industry standards and specifications, the minimum number of cuts required for synthesizing a coal sample from all subsamples or reduced subsamples should be 60. Therefore, the total number of oscillations of the guide plate 32 during the entire reduction process can be calculated to be 60. The time for each oscillation can be obtained using the formula t / (60×60), which ensures that the guide plate 32 can accurately stop at the predetermined position during each cut, thereby completing an effective sample collection.

[0069] In actual operation, the driver 33 drives the guide plate 32 to rotate via a precision transmission rod 34. When the guide plate 32 reaches the predetermined position to collect the sample, it only needs to stay for a very short time t / (60×60) to complete a precise cutting operation. This process is repeated 60 times until the entire coal sample is uniformly reduced to 60 subsamples. In this way, not only is the precise adjustment of the intelligent reduction ratio achieved, but the automation level and efficiency of the reduction process are also greatly improved.
