Description

Technical Field

[0001] This utility model relates to the field of conveyor unloading equipment, and in particular to a controllable unloading device with upper and lower split components. Background Technology

[0002] In modern industrial production, conveyors are widely used as important material handling equipment in various fields, such as mining, metallurgy, building materials, and chemicals. Currently, common types of conveyors include belt conveyors, screw conveyors, and scraper conveyors.

[0003] For belt conveyors, a drive roller drives the conveyor belt to transport materials from one end to the other. During unloading, a discharge hopper is typically installed at the end of the conveyor belt, and the material falls into the receiving device below under its own weight. However, this unloading method makes it difficult to precisely control the discharge volume, as factors such as the conveyor belt speed and the material accumulation condition can affect the discharge amount.

[0004] Regarding the aforementioned technologies, the existing plow blades of the plow unloader are prone to friction with the conveyor belt, which can easily cause wear and tear on both the conveyor belt and the plow blades. In addition, with the development of intelligent mines, some mines need to control the conveying speed when transporting materials, and traditional plow unloaders have some difficulty in controlling the feeding amount. Utility Model Content

[0005] In order to make the unloading rate of the conveyor more controllable, this utility model provides a controllable unloading device with upper and lower split parts.

[0006] This utility model provides a controllable unloading device with upper and lower separation, which adopts the following technical solution:

[0007] A controllable unloading device with upper and lower split structure includes a support mechanism, a lifting mechanism and an unloading mechanism. The support mechanism includes a vertical frame and a connecting frame, and the connecting frame is disposed at the top of the vertical frame.

[0008] The lifting mechanism includes a first telescopic cylinder and a fixed frame. The fixed frame is fixedly installed on the connecting frame, and the cylinder body of the first telescopic cylinder is fixedly installed at the bottom end of the fixed frame.

[0009] The unloading mechanism includes an unloading plow, which includes a fixed part and two unloading parts. One end of each of the two unloading parts is fixedly connected to each other at a certain angle. Both unloading parts are fixed on the fixed part. The end of the fixed part away from the unloading part is connected to the telescopic rod of the first telescopic cylinder.

[0010] By adopting the above technical solution, when unloading is required, workers can adjust the distance between the unloading section and the belt by controlling the extension length of the telescopic rod of the first telescopic cylinder according to the actual material unloading volume. Thus, when material is conveyed on the belt, material exceeding the height of the unloading section will be smoothly pushed to both sides of the belt by the unloading section and then fall into the designated receiving area. At this point, some material will remain on the belt, which will participate in unloading again in subsequent stages as the belt continues to operate. This method achieves graded unloading, effectively reducing the pressure on the unloading plow during unloading, and allows for reasonable control of the unloading volume, thereby optimizing unloading efficiency and providing strong support for the orderly progress of industrial production.

[0011] Optionally, the lower end of the unloading mechanism is further provided with a material support mechanism, which includes a material support frame, a roller frame and rollers. The material support frame is arranged between the uprights along the conveying direction of the belt, the roller frame is arranged at the upper end of the material support frame, and multiple rollers are provided, all of which are rotatably arranged on the roller frame.

[0012] By adopting the above technical solution, during the unloading process, the belt is conveyed onto the rollers. Because the bottom end of the belt is arc-shaped during transport on the conveyor, the rollers contact the bottom end of the belt, flattening the entire belt. This allows for more uniform unloading by the unloading plow in the unloading mechanism above the belt, and more precise control of the unloading volume during the height adjustment process of the unloading plow. When the belt is flattened, the unloading plow in the unloading mechanism can achieve more uniform unloading. Material at different locations can be unloaded at different gradient rates, avoiding local accumulation or insufficient unloading, thus improving the overall unloading quality. Simultaneously, the uniformity of unloading ensured during the height adjustment process of the unloading plow allows for more precise control of the unloading volume.

[0013] Optionally, the material support mechanism further includes a movable plate, a fixed plate, a material support telescopic cylinder, a guide shaft, a guide sleeve, and a mounting frame. The fixed plate is fixedly mounted on the material support frame at both ends. The bottom end of the movable plate is slidably disposed on the upper end of the material support frame. The upper end of the movable plate is provided with multiple sliding support inclined surfaces. The bottom end of the roller frame slides on the sliding support inclined surfaces. The cylinder body of the material support telescopic cylinder is fixedly mounted on the fixed plate. The telescopic rod of the material support telescopic cylinder is connected to the movable plate. Two mounting frames are provided. The mounting frames are respectively disposed on the material support frame at the lower end of the movable plate and the fixed plate. One end of the guide shaft is fixedly mounted on the bottom end of the roller frame. The other end of the guide shaft is slidably engaged with the guide sleeve. The other end of the guide sleeve is fixedly mounted on the upper end of the mounting frame.

[0014] By adopting the above technical solution, this device demonstrates significant advantages in practical applications when adjusting the height of the rollers. The telescopic cylinder extends the telescopic rod, pushing the movable plate to slide on the upper end of the material support frame. The telescopic cylinder is typically hydraulically or electrically driven, ensuring stable movement of the movable plate and a smooth, reliable height adjustment process. During the sliding of the movable plate, the bottom end of the roller frame slides on an inclined sliding support surface, and the height of the roller frame is adjusted through the sliding cooperation of the guide shaft and guide sleeve. This design makes height adjustment more precise, and the presence of the guide shaft also improves the stability of the adjustment process, preventing the roller frame from shifting or wobbling. This device is applicable to conveyor belts of various heights, greatly improving the equipment's versatility. For example, in different industrial production scenarios, various specifications of conveyors may be used, and by adjusting the height of the roller frame, this device can easily adapt to these different devices without requiring a specific unloading device for each conveyor. Furthermore, adjusting the height of the roller frame according to working conditions brings great convenience to actual production. For example, in a narrow workshop, lowering the height of the roller frame can prevent collisions with other equipment; when it is necessary to increase the unloading speed, the height of the roller frame can be appropriately increased to optimize the unloading angle and improve unloading efficiency.

[0015] Optionally, the material support mechanism further includes a support wheel, and multiple support wheels are provided. The support wheels are all fixedly installed at the bottom end of the roller frame. A first slot is provided on the wheel surface of the support wheel, and the support wheel rolls relative to the sliding support inclined surface through the first slot.

[0016] By adopting the above technical solution, when the movable plate moves, the support roller rolls on the sliding support slopes of the movable and fixed plates. The first slot reduces the possibility of the support roller derailing from the fixed or movable plate, improving sliding stability. Simultaneously, by setting the support roller, the friction between the roller frame and the movable and fixed plates changes from sliding friction to rolling friction, reducing friction and making the movable plate move more flexibly. This also makes raising and lowering the roller frame easier and adjusting the roller height more convenient.

[0017] Optionally, a limiting slope is also provided at the upper end of the movable plate.

[0018] By adopting the above technical solution, when driving the movable plate to move, the limiting slope is set to allow the supporting rollers on the movable plate to have a rolling range, reducing the possibility of the supporting rollers exceeding the travel range and derailing, thus improving the safety of the device.

[0019] Optionally, the material support mechanism further includes multiple sliding wheels, which are disposed on the upper end of the mounting frame. A second groove is formed on the surface of each sliding wheel, and the bottom end of the movable plate rolls relative to the sliding wheel through the second groove.

[0020] By adopting the above technical solution, during the movement of the movable plate, it can move on the mounting frame by contacting the sliding wheel at the bottom. The second slot on the sliding wheel can guide the movement of the movable plate, making the movement of the movable plate more precise and reducing the possibility of derailment.

[0021] Optionally, the unloading mechanism further includes unloading plates, and two unloading plates are provided. The two unloading plates are respectively provided on both sides of the unloading part, and the end of the unloading plate away from the unloading part is set at a certain angle to the unloading part.

[0022] By adopting the above technical solution, the material, after being guided, is smoothly and orderly detached from the conveyor belt under the unique guiding and conveying action of the unloading plate. This guiding and conveying action, through route design, can be adjusted according to the characteristics of the material and the running speed of the belt, thereby ensuring that the material maintains a good trajectory at the moment of detachment from the belt, minimizing collisions and friction between the material and the equipment. At the same time, the material falling into the receiving area can be neatly piled up, facilitating subsequent centralized processing and transportation, further improving the smoothness and efficiency of the entire production process.

[0023] Optionally, the unloading mechanism further includes two side plow blades, which are disposed at the bottom end of the unloading section, with one side plow blade corresponding to one unloading section.

[0024] By adopting the above technical solution, when unloading material from the conveyor belt, the height of the unloading section can be adjusted by the lifting mechanism. This allows for precise adjustment of the bottom end of the side plow blades at the bottom of the unloading section to the optimal contact position with the belt, based on the actual height of the belt and the characteristics of the material. For example, the belt height may vary on different production lines; the lifting mechanism can respond quickly and adjust accordingly, ensuring the accuracy and stability of the unloading operation. The side plow blades play a crucial role in the unloading process. They guide the material off the belt, achieving uniform unloading. The design of the side plow blades is carefully considered; their angle and length parameters effectively guide material flow, preventing material accumulation and blockage. Furthermore, the side plow blades are typically made of wear-resistant, high-strength materials to ensure good unloading performance over long-term use. The gap between the two side plow blades allows for graded unloading. In actual production, some materials may require classification or targeted conveying at different production stages. Through this gap, the remaining material can continue to be conveyed on the belt, achieving the function of graded unloading. This provides strong support for optimizing production processes and increasing the flexibility of material handling.

[0025] Optionally, the unloading mechanism further includes guide plates, and two guide plates are provided. Both guide plates are provided at both ends of the unloading section, and one unloading section corresponds to one guide plate.

[0026] By adopting the above technical solution, when it is necessary to unload material from the belt, the unloading plow head is lowered to a designated height. Under the transport action of the belt, the material on the upper layer of the belt is unloaded into the unloading area, and the material on the lower layer passes normally through the unloading plow head. Due to the unloading plow head, after the remaining material passes through the unloading plow head, the material will be spread flat on the belt. During the continued conveying process, due to the conveyor rollers of the conveyor, the bottom end of the belt will gradually return to a bent state. During the gradual bending of the belt, the flat material will be scattered in other areas, causing some waste. By setting a guide plate at the rear end of the unloading section, the guide plate can gather the material at the edge of the belt during the conveying process. After the belt is bent, the material can be more concentrated in the middle of the belt, reducing the possibility of material spillage.

[0027] Optionally, the lifting mechanism further includes a slide, a pulley, and a crossbeam. The pulley is disposed inside the slide, and a slide is disposed at each end of the crossbeam. The slide is slidably disposed on the upright frame via the pulley, and one slide corresponds to one upright frame. An installation rod is fixedly installed at the upper end of the unloading part, and both ends of the installation rod are connected to the crossbeam.

[0028] By adopting the above technical solution, the design utilizes pulleys sliding on the upright frame, allowing the unloading section to run smoothly along a predetermined track during lifting. The sliding blocks provide support and guidance for the sliding, ensuring it doesn't deviate from its direction, while the pulleys reduce friction between the sliding block and the upright frame, making the lifting process smoother, reducing the possibility of jamming and shaking, and improving the stability and reliability of the equipment. A sliding block is installed at each end of the crossbeam, allowing the two blocks to move synchronously, ensuring the levelness of the unloading section during lifting. Simultaneously, the crossbeam also increases the rigidity and strength of the entire lifting mechanism, enabling it to withstand the weight of the unloading section and the material, preventing deformation and damage.

[0029] In summary, this utility model has at least one of the following beneficial technical effects:

[0030] 1. By setting up a unloading mechanism, it is possible to achieve graded unloading, effectively reduce the pressure on the unloading plow during the unloading process, and reasonably control the unloading volume, thereby optimizing the unloading effect and providing strong support for the orderly advancement of industrial production.

[0031] 2. By setting up a material support mechanism, materials at different locations can be unloaded at different gradient rates, avoiding local accumulation or insufficient unloading and improving the overall quality of unloading. Simultaneously, during the height adjustment process of the unloading plow, the uniformity of unloading ensures more precise control of the unloading volume.

[0032] 3. By installing a discharge plate, the material maintains a good trajectory the moment it leaves the conveyor belt, minimizing collisions and friction between the material and the equipment. Simultaneously, the material falling into the receiving area can be neatly stacked, facilitating subsequent centralized processing and transportation, further improving the smoothness and efficiency of the entire production process.

[0033] 4. By setting up side plow blades, the function of graded unloading is realized, which provides strong support for the optimization of production process and the flexibility of material handling. Attached Figure Description

[0045] The following combination Figures 1 to 10 The present invention will be described in further detail below.

[0046] This utility model discloses a controllable unloading device with upper and lower separation. (Refer to...) Figures 1-10 A controllable unloading device with upper and lower split mainly includes a support mechanism 100, a lifting mechanism 200, an unloading mechanism 300 and a material support mechanism 400. The support mechanism 100 includes a vertical frame 110 and a connecting frame 120, with the connecting frame 120 located at the top of the vertical frame 110.

[0047] The lifting mechanism 200 includes a first telescopic cylinder 210 and a fixed frame 220. The fixed frame 220 is fixedly installed on the connecting frame 120, and the cylinder body of the first telescopic cylinder 210 is fixedly installed at the bottom end of the fixed frame 220.

[0048] The unloading mechanism 300 includes an unloading plow 310, which includes a fixed part 311 and two unloading parts 312. One end of each of the two unloading parts 312 is fixedly connected to each other at a certain angle. Both unloading parts 312 are fixed on the fixed part 311. The end of the fixed part 311 away from the unloading parts 312 is connected to the telescopic rod of the first telescopic cylinder 210.

[0049] The material support mechanism 400 includes a material support frame 401, a roller frame 402, and rollers 403. The material support frame 401 is arranged between the uprights 110 along the conveying direction of the belt. The roller frame 402 is arranged at the upper end of the material support frame 401. Multiple rollers 403 are provided, and all rollers 403 are rotatably arranged on the roller frame 402.

[0050] When unloading is required, workers can adjust the distance between the unloading section 312 and the belt by controlling the extension length of the telescopic rod of the first telescopic cylinder 210, based on the actual material unloading volume. Thus, when material is conveyed on the belt, material exceeding the height of the unloading section 312 will be smoothly pushed to both sides of the belt by the unloading section 312 and then fall into the designated receiving area. At this point, some material will remain on the belt, which will participate in unloading again in subsequent stages as the belt continues to operate. This method achieves graded unloading, effectively reducing the pressure on the unloading plow 310 during unloading, and allows for reasonable control of the unloading volume, thereby optimizing unloading efficiency and providing strong support for the orderly progress of industrial production.

[0051] During the unloading process, the belt is conveyed onto the roller 403. Since the bottom of the belt is curved during transport on the conveyor, the roller 403 contacts the bottom of the belt, flattening the entire belt. This allows the unloading plow 310 in the unloading mechanism 300 above the belt to unload more evenly, and makes the unloading volume control more precise during the height adjustment process of the unloading plow 310. When the belt is flattened, the unloading plow 310 in the unloading mechanism 300 can achieve more uniform unloading. Material at different locations can be unloaded at different gradient rates, avoiding local accumulation or insufficient unloading, thus improving the overall unloading quality. Simultaneously, the uniformity of unloading ensured during the height adjustment process of the unloading plow 310 allows for more precise control of the unloading volume.

[0052] Reference Figure 1 , Figure 8 , Figure 9 and Figure 10In some embodiments, the material support mechanism 400 further includes a movable plate 404, a fixed plate 405, a material support telescopic cylinder 406, a guide shaft 407, a guide sleeve 415, and a mounting frame 408. The fixed plate 405 is fixedly mounted on the material support frame 401 at both ends. The bottom end of the movable plate 404 is slidably mounted on the upper end of the material support frame 401. The upper end of the movable plate 404 is provided with multiple sliding support inclined surfaces 411. The bottom end of the roller frame 402 slides on the sliding support inclined surfaces 411. The cylinder body of the material support telescopic cylinder 406 is fixedly mounted on the fixed plate 405. The telescopic rod of the material support telescopic cylinder 406 is connected to the movable plate 404. Two mounting frames 408 are provided. The mounting frames 408 are respectively mounted on the material support frame 401 at the lower end of the movable plate 404 and the fixed plate 405. One end of the guide shaft 407 is fixedly mounted on the bottom end of the roller frame 402. The other end of the guide shaft 407 is slidably engaged with the guide sleeve 415. The other end of the guide sleeve 415 is fixedly mounted on the upper end of the mounting frame 408.

[0053] In practical applications, this device demonstrates significant advantages when adjusting the height of roller 403. The telescopic cylinder 406 extends the telescopic rod, pushing the movable plate 404 to slide on the upper end of the support frame 401. The telescopic cylinder 406, typically hydraulically or electrically driven, stably moves the movable plate 404, ensuring a smooth and reliable height adjustment process. During the sliding of the movable plate 404, the bottom end of the roller frame 402 slides on the inclined sliding support slope 411, and the height of the roller frame 402 is adjusted through the sliding engagement of the guide shaft 407 and the guide sleeve 415. This design makes height adjustment more precise, and the presence of the guide shaft 407 also improves the stability of the adjustment process, preventing the roller frame 402 from shifting or wobbling. This device is applicable to conveyor belts of various heights, greatly improving the equipment's versatility. For example, various specifications of conveyors may be used in different industrial production scenarios. By adjusting the height of the idler frame 402, this device can easily adapt to these different devices without requiring a specific unloading device for each type of conveyor. At the same time, adjusting the height of the idler frame 402 according to working conditions also brings great convenience to actual production. For instance, in workshops with limited space, lowering the height of the idler frame 402 can prevent collisions with other equipment; when it is necessary to increase the unloading speed, the height of the idler frame 402 can be appropriately raised to optimize the unloading angle and improve unloading efficiency.

[0054] Reference Figure 8 In some embodiments, the material support mechanism 400 further includes a support wheel 409. Multiple support wheels 409 are provided, and all support wheels 409 are fixedly installed at the bottom end of the roller frame 402. A first groove 410 is provided on the wheel surface of the support wheel 409, and the support wheel 409 rolls relative to each other on the sliding support inclined surface 411 through the first groove 410.

[0055] When the movable plate 404 moves, the support roller 409 rolls on the sliding support slope 411 on the movable plate 404 and the fixed plate 405. By setting the first slot 410, the possibility of the support roller 409 derailing from the fixed plate 405 or the movable plate 404 can be reduced, thus improving the stability of sliding. At the same time, by setting the support roller 409, the friction between the roller frame 402 and the movable plate 404 and the fixed plate 405 is changed from sliding friction to rolling friction, which reduces the friction force, makes the movable plate 404 move more flexibly, makes the roller frame 402 easier to raise and lower, and makes the height adjustment of the roller shaft 403 more convenient.

[0056] Reference Figure 9 In some embodiments, a limiting inclined surface 412 is also provided at the upper end of the movable plate 404.

[0057] When the movable plate 404 is driven to move, the limiting inclined surface 412 is set to allow the supporting roller 409 on the movable plate 404 to have a rolling range, reducing the possibility of the supporting roller 409 exceeding the travel range and derailing, thus improving the safety of the device.

[0058] Reference Figure 10 In some embodiments, the material support mechanism 400 further includes a sliding wheel 413. Multiple sliding wheels 413 are provided. The sliding wheels 413 are located on the upper end of the mounting frame 408. A second slot 414 is provided on the wheel surface of the sliding wheel 413. The bottom end of the movable plate 404 rolls relative to the sliding wheel 413 through the second slot 414.

[0059] During the movement of the movable plate 404, it can move on the mounting bracket 408 by contacting the sliding wheel 413 at its bottom end. The second slot 414 on the sliding wheel 413 can guide the movement of the movable plate 404, making the movement of the movable plate 404 more precise and reducing the possibility of derailment.

[0060] Reference Figure 5 and Figure 6 In some embodiments, the unloading mechanism 300 further includes an unloading plate 320. Two unloading plates 320 are provided, and the two unloading plates 320 are respectively provided on both sides of the unloading part 312. The end of the unloading plate 320 away from the unloading part 312 is set at a certain angle to the unloading part 312.

[0061] After being guided, the material is smoothly and orderly detached from the belt by the unique guiding and conveying action of the discharge plate 320. This guiding and conveying action is designed to adjust according to the characteristics of the material and the belt speed, ensuring that the material maintains a good trajectory at the moment of detachment and minimizing collisions and friction between the material and the equipment. Simultaneously, the material falling into the receiving area can be neatly stacked, facilitating subsequent centralized processing and transportation, further improving the smoothness and efficiency of the entire production process.

[0062] Reference Figure 4 In some embodiments, the unloading mechanism 300 further includes a side plow blade 330. Two side plow blades 330 are provided and are located at the bottom end of the unloading section 312. One unloading section 312 corresponds to one side plow blade 330.

[0063] When unloading material from the conveyor belt, the lifting mechanism 200 adjusts the height of the unloading section 312, accurately positioning the bottom of the side plow blades 330 at the optimal contact point with the belt based on the actual belt height and material characteristics. For example, the belt height may vary on different production lines; the lifting mechanism 200 responds quickly and adjusts accordingly, ensuring the accuracy and stability of the unloading operation. The side plow blades 330 play a crucial role in the unloading process. They guide the material off the belt, achieving uniform unloading. The side plow blades 330 are carefully designed; their angle and length effectively guide material flow, preventing accumulation and blockage. Furthermore, the side plow blades 330 are typically made of wear-resistant, high-strength materials to ensure consistent unloading performance over long-term use. The gap between the two side plow blades 330 allows for graded unloading. In actual production, some materials may require classification or targeted conveying at different production stages. Through this gap, the remaining material can continue to be conveyed on the belt, achieving the function of graded unloading. This provides strong support for the optimization of production processes and the flexibility of material handling.

[0064] Reference Figure 6 and Figure 7 In some embodiments, the unloading mechanism 300 further includes a guide plate 340. Two guide plates 340 are provided, and both guide plates 340 are provided at both ends of the unloading section 312. One unloading section 312 corresponds to one guide plate 340.

[0065] When unloading material from the belt is required, the unloading plow 310 is lowered to a designated height. Under the transport action of the belt, the material on the upper layer of the belt is unloaded into the unloading area, and the material on the lower layer passes normally through the unloading plow 310. Due to the unloading plow 310, after the remaining material passes through the unloading plow 310, the material will be spread flat on the belt. During the continued conveying process, due to the conveyor rollers of the conveyor, the bottom end of the belt will gradually return to a bent state. During the gradual bending of the belt, the flat material will be scattered in other areas, causing some waste. By setting a guide plate 340 at the rear end of the unloading section 312, the guide plate 340 can gather the material at the edge of the belt during the conveying process. After the belt is bent, the material can be more concentrated in the middle of the belt, reducing the possibility of material spillage.

[0066] Reference Figures 1-3 ,as well as Figure 5 In some embodiments, the lifting mechanism 200 further includes a slide 230, a pulley 240, and a crossbeam 250. The pulley 240 is disposed inside the slide 230, and a slide 230 is disposed at each end of the crossbeam 250. The slide 230 is slidably disposed on the upright 110 via the pulley 240, and one slide 230 corresponds to one upright 110. An installation rod 260 is fixedly installed on the upper end of the unloading part 312, and the two ends of the installation rod 260 are connected to the crossbeam 250.

[0067] The sliding mechanism 240 on the upright 110 allows the unloading section 312 to move smoothly along a predetermined track during lifting. The sliding block 230 provides support and guidance for the sliding, ensuring it doesn't deviate from its direction, while the pulley 240 reduces friction between the sliding block and the upright 110, making the lifting process smoother, reducing the possibility of jamming and shaking, and improving the stability and reliability of the equipment. A sliding block 230 is installed at each end of the crossbeam 250, allowing the two sliding blocks 230 to move synchronously, ensuring the levelness of the unloading section 312 during lifting. At the same time, the crossbeam 250 also increases the rigidity and strength of the entire lifting mechanism 200, enabling it to withstand the weight of the unloading section 312 and the material, preventing deformation and damage.

[0068] The implementation principle of the upper and lower split controllable unloading device of this utility model is as follows:

[0069] When unloading is required, workers can adjust the extension length of the first telescopic cylinder 210 according to the material unloading volume demand, thereby adjusting the distance between the unloading section 312 and the belt. In this way, material exceeding the height of the unloading section 312 on the belt will be pushed to both sides of the belt and fall into the receiving area, while some material will continue to be unloaded. This method enables graded unloading, reduces the pressure on the unloading plow 310, and allows for reasonable control of the unloading volume.

[0070] The above are all preferred embodiments of the present invention and are not intended to limit the scope of protection of the present invention. Therefore, all equivalent changes made in accordance with the structure, shape and principle of the present invention should be covered within the scope of protection of the present invention.
