Description

Technical Field

[0001] This invention relates to the field of unloader technology, and in particular to a non-lifting single-sided unloader. Background Technology

[0002] In many industrial sectors such as power, metallurgy, coal, chemical, and building materials, belt conveyors are the core equipment for continuous transport of bulk materials. Their matching unloading devices directly determine the efficiency, accuracy, and stability of material transport and equipment operation. As a key component of belt conveyors, the single-sided unloader is widely used in production scenarios that require single-sided diversion unloading due to its compact structure and controllable unloading direction. It can be adapted to belt conveyors of various types and widths to achieve multi-point precise unloading operations.

[0003] Most existing single-sided unloaders adopt a lifting structure design. Their core working principle is to drive the plow and the lifting device to lift and lower as a whole through the lifting mechanism, thereby realizing the switching between the unloading state and the non-unloading state. Although this type of lifting unloader meets the basic unloading requirements to a certain extent.

[0004] The unloading state switching is inflexible and its applicable scenarios are limited. When switching between unloading and non-unloading states, the lifting single-sided unloader must ensure that the conveyor belt is empty. It is impossible to complete the state switching in the middle of the conveyor belt feeding. This makes it extremely unsuitable for production scenarios with continuous conveying and frequent unloading, which greatly reduces the overall production efficiency and cannot meet the continuous and efficient operation requirements in industrial production.

[0005] The equipment suffers from poor versatility and insufficient adaptability. The lifting device height of existing lifting single-sided unloaders is mostly fixed, making it impossible to adapt to the thickness and wear of the conveyor belt. This makes it difficult to adapt to belt conveyors of different specifications, thus limiting its applicability.

[0006] Therefore, it is necessary to invent a non-lifting single-sided unloader to solve the above problems. Summary of the Invention

[0007] The purpose of this invention is to provide a non-lifting single-sided unloader to solve the problems of poor flexibility in switching unloading states and limited applicability in the above-mentioned background art.

[0008] To achieve the above objectives, the present invention provides the following technical solution: a non-lifting single-sided unloader, comprising a conveyor belt used in conjunction with a conveying mechanism, including a support, an unloading lifting device located above the support, and a plow device, characterized in that a hydraulic device for driving the plow device to rotate is installed on the top of the support. Also includes: A synchronous adjustment device installed on the top of the support drives the unloading lifting device to rise and fall when the plow device rotates clockwise and counterclockwise. The power storage device is installed at the unloading lifting device and the synchronous adjustment device. It stores power when the synchronous adjustment device slides, and applies upward falling force to the unloading lifting device and reset force to the synchronous adjustment device, respectively.

[0009] Optionally, the synchronous adjustment device includes several rails mounted on the top of the support and sliding components that slide along the rails. The sliding components lift or lower the unloading lifting device by sliding. Two gears are symmetrically mounted on the top of the bracket. One of the gears rotates with the plow mechanism, thereby pushing the sliding assembly to slide back and forth.

[0010] Optionally, the sliding assembly includes a sliding plate that slides along the length of the track, with gear racks provided at both ends of the sliding plate, and the front gear rack meshing with gear 1. A support frame plate is installed on the top of the sliding plate, and a right-angled triangular groove is opened on the top of the support frame plate to cooperate with the unloading and lifting device.

[0011] Optionally, the unloading lifting device includes a lifting frame set below the conveyor belt and two sets of roller frames slidably mounted on the lifting frame. The roller frames are U-shaped, and there is an adjustment space between the inner wall of the roller frames and the lower surface of the lifting frame for the energy storage device to pass through. A small wheel is rotatably mounted on the outer side of the roller frame, rolling along the hypotenuse of a right-angled triangular groove; Two limiting plates are installed on the top of the bracket, which contact the two ends of the support frame respectively, to limit the sliding of the support frame.

[0012] Optionally, the power storage device includes a U-shaped frame plate with its opening facing the synchronous adjustment device and a pad plate passing through the unloading lifting device. The pad plate is provided with a pad plate assembly for adjusting the height of the unloading lifting device, and a power storage assembly is provided between the inner side wall of the U-shaped frame plate and the end of the synchronous adjustment device.

[0013] Optionally, the power storage component includes an elastic structure fixed to the inner wall of the U-shaped frame plate. A pad plate 2 is fixedly installed at the end of the elastic structure away from the U-shaped frame plate, and multiple ball bearings that are in contact with the synchronization adjustment device are rotatably installed on the pad plate 2.

[0014] Optionally, the pad assembly is in the shape of a right triangle, and the hypotenuse of the pad assembly has the same inclination angle as the inner wall of the roller frame and is in contact with it.

[0015] Optional, also includes: Several pressing devices are installed on the top of the support and connected to the synchronous adjustment device. The pressing devices rotate with the plow device in the initial stage of rotation. In the unloading state, they cooperate with the unloading lifting device to flatten the conveyor belt. In the non-unloading state, they clean the edge of the conveyor belt.

[0016] Optionally, the pressing device includes a mounting bracket rotatably mounted on top of the bracket, a gear two fixedly mounted on the outside of the mounting bracket, and a pressing plate mounted on top of the mounting bracket; Gear 2 meshes with the rack at the rear end and drives the lower pressure plate to rotate under the drive of the rack; When the unloading lifting device is in the rising state, the lower pressure plate rotates to the longitudinal horizontal state, and when the unloading lifting device is in the descending state, the lower pressure plate rotates to the inclined state to clean the edge of the conveyor belt.

[0017] Optionally, the plow assembly includes a plow body and a support shaft rotatably mounted on top of the bracket and fixed to the plow body. A cleaning pad that contacts the conveyor belt in the unloading state is bonded to the bottom of the plow body, and a hinge frame that is hinged to the hydraulic device is fixedly mounted on the rear side of the plow body.

[0018] The technical effects and advantages of this invention are as follows: This invention utilizes a rotating plow-type device to intercept and unload materials during the conveyor belt feeding process. This avoids material buildup between the lifting unloader and the conveyor belt during the descent interception. Furthermore, the accumulator device compresses the unloading support device, preventing jamming issues and improving the unloading efficiency of the plow-type device on the conveyor belt, thus preventing material residue.

[0019] The present invention enables adaptive adjustment of the overall height of the unloading lifting device during the storage of energy by setting up a power storage device, thereby improving the applicability of the unloading lifting device. At the same time, it ensures a tight fit between the plow device and the conveyor belt, and can also drive the synchronous adjustment device to actively achieve transmission with the plow device when contacting the unloading.

[0020] The adjustable space of this invention can ensure that the power storage device can pass through smoothly, and also provide sufficient room for the roller frame to slide up and down, avoiding interference between the roller frame and the power storage device. At the same time, it provides adjustment space for the pad assembly to adjust the initial height of the lifting frame, ensuring that the unloading lifting device can be adapted to conveyor belts of different thicknesses and improving the versatility of the equipment.

[0021] The present invention can simultaneously store force when the sliding plate slides horizontally by setting the force storage component, which not only provides sufficient reset force for the sliding plate to reset, but also transmits upward auxiliary lifting force to the lifting frame through the pad and the pad assembly.

[0022] The pressing device of this invention is a key component in the equipment that has the dual functions of flattening the conveyor belt and cleaning materials. Its operation rhythm is synchronized with the rotation of the plow device. In the initial stage when the plow device starts to rotate counterclockwise and clockwise under the drive of the hydraulic device, it will follow the rotation under the power transmission of the synchronization adjustment device, adjust its posture in advance, and prepare for the subsequent unloading operation, so as to avoid problems such as conveyor belt wrinkles or material residue caused by the lag in the operation.

[0025] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0026] Most existing single-sided unloaders adopt a lifting structure, that is, the plow and the lifting device are raised or lowered as a whole through the lifting mechanism to achieve the switching between unloading and non-unloading states.

[0027] The lifting-type single-sided unloader has many defects: 1. When switching unloading states, the conveyor belt must be empty before switching, and it cannot be switched during feeding; 2. During the lifting process, problems such as jamming and deviation are prone to occur, resulting in a decrease in unloading accuracy and even damage to the conveyor belt; 3. It is difficult to effectively clean the edge of the conveyor belt when not unloading, which can easily cause material residue.

[0028] This invention provides, for example Figure 1-12 The non-lifting single-sided unloader shown is used in conjunction with the conveyor belt of the conveying mechanism. It can be precisely adapted to belt conveyors of different widths and thicknesses to achieve efficient single-sided unloading of bulk materials. Its core structure includes a support 100, an unloading lifting device 200 located above the support 100, and a plow device 300. The two are matched to each other to ensure smooth and coordinated unloading action and flexible rotation of the plow device 300 to complete the switching between unloading and non-unloading states. A hydraulic device 400 for driving the plow device 300 to rotate is installed on the top of the support 100. In this embodiment, the hydraulic device 400 can be implemented using various existing technologies such as linear motors, hydraulic rods, or electric push rods; To solve the problems of asynchronous operation and unstable operation of existing unloaders: The unloader also includes: The synchronous adjustment device 500 installed on the top of the bracket 100 drives the unloading lifting device 200 to rise and fall when the plow device 300 rotates counterclockwise and clockwise, ensuring that the conveyor belt is always in a flat state during unloading. In this embodiment, the synchronous adjustment device 500 can use various existing technologies such as linkage mechanism, gear transmission mechanism or hydraulic circuit drive to drive the unloading lifting device 200 to rise and fall while driving the plow device 300 to rotate counterclockwise and clockwise. The power storage device 600 is installed at the unloading lifting device 200 and the synchronous adjustment device 500. It stores power when the synchronous adjustment device 500 slides. On the one hand, it applies an upward lifting force to the unloading lifting device 200 to assist it in smooth lifting and reducing the driving load. At the same time, it can adapt to conveyor belts of different thicknesses or wear levels. On the other hand, it applies a reset force to the synchronous adjustment device 500 to ensure that it can quickly and accurately reset after the unloading action is completed.

[0029] The hydraulic device 400 adopts a hydraulic cylinder structure, which has sufficient driving force and smooth operation. It is specifically used to drive the plow device 300 to rotate clockwise and counterclockwise around its support structure to meet the needs of different unloading scenarios.

[0030] The plow device 300, with its rotating design, can intercept and unload materials during the conveyor belt feeding process. This prevents residual material from being compacted between the lifting unloader and the conveyor belt during the descent interception. In addition, the accumulator device 600, in conjunction with the extrusion device 200, compresses the unloading support device, avoiding the problem of jamming. This also improves the unloading effect of the plow device 300 on the conveyor belt and prevents material residue.

[0031] The storage device 600 allows for adaptive adjustment of the overall height of the unloading lifting device 200 during storage, thereby expanding the applicability of the unloading lifting device 200. It also ensures a tight fit between the plow device 300 and the conveyor belt, and can drive the synchronous adjustment device 500 to actively transmit power to the plow device 300 when contacting the unloading device.

[0032] The working principle of this embodiment is as follows: During unloading, the hydraulic device 400 is activated to extend, driving the plow device 300 to rotate upwards on the conveyor belt. During this rotation, the synchronous adjustment device 500 slides, driving the unloading lifting device 200 to rise as a whole. Simultaneously, the accumulator device 600 is compressed and stored. Just as the plow device 300 is about to rotate above the conveyor belt, the unloading lifting device 200 completes its lifting and disconnects the drive to the synchronous adjustment device 500, causing the synchronous adjustment device 500 to stop sliding.

[0033] When unloading stops, the hydraulic device 400 is activated to retract, causing the hydraulic device 400 to drive the plow device 300 to rotate and reset. Due to the reset force applied by the accumulator 600 to the synchronizing device 500, the synchronizing device 500 resumes transmission at the first moment the plow device 300 resets, so that the plow device 300 drives the synchronizing device 500 to reset at the same time, thereby causing the unloading lifting device 200 to descend and the accumulator 600 to release the accumulator.

[0034] In some embodiments of the present invention, reference is made to... Figure 3 and Figure 4 As shown, the synchronous adjustment device 500 includes several tracks 510 installed on the top of the support 100 and sliding components 520 that slide along the tracks 510. Preferably, there are two tracks 510, which are installed parallel and symmetrically on the top end face of the support 100. Their extension direction is consistent with the direction of the conveyor belt. They are used to limit and guide the sliding of the sliding components 520 to avoid deviation during the sliding process. The sliding components 520 lift or lower the unloading lifting device 200 by sliding. The sliding components 520 convert the horizontal kinetic energy into the vertical lifting kinetic energy of the unloading lifting device 200 through their own horizontal sliding, thereby smoothly lifting or lowering the unloading lifting device 200 and ensuring that the conveyor belt can be lifted to a height that matches the plow device 300 during unloading. Two gears 530 are symmetrically mounted on the top of the bracket 100. One of the gears 530 rotates with the plow device 300 and pushes the sliding component 520 to slide back and forth. The gear 530 is used to convert the rotational motion of the plow device 300 into the horizontal back and forth sliding of the sliding component 520, thereby driving the unloading lifting device 200 to complete the lifting action, so as to realize the synchronous linkage between the plow device 300 and the unloading lifting device 200.

[0035] In some embodiments of the present invention, reference is made to... Figure 12 As shown, the shafts of both gears 530 extend to the bottom of the bracket 100, and gears 540 are rotatably mounted on the bottom of the bracket 100 and the bottom of one of the gears 530. The two gears 540 mesh with each other, and one of the gears 540 is connected to the other gear 530 through a belt pulley drive, so that the two gears 530 rotate simultaneously and in opposite directions, thereby ensuring the smoothness of the sliding component 520 and preventing the sliding component 520 from tilting due to uneven force during the sliding process, which would affect the unloading effect.

[0036] In some embodiments of the present invention, reference is made to... Figure 5 , Figure 6 It's hot Figure 10As shown, the sliding assembly 520 includes a sliding plate 521 that slides along the length of the track 510. The bottom of the sliding plate 521 is rolled with balls to reduce friction. Both ends of the sliding plate 521 are provided with gear racks 522. The gear rack 522 at the front end meshes with the gear 530 and is responsible for receiving the rotational power transmitted by the gear 530, driving the sliding plate 521 to slide back and forth. After sliding a certain distance, it disconnects from the gear 530, causing the sliding plate 521 to stop sliding without affecting the normal rotation of the plow device 300. Under the action of the power storage device 600, it immediately re-meshes with the gear 530 when the plow device 300 rotates in the opposite direction. A support frame plate 523 is installed on the top of the sliding plate 521. The support frame plate 523 is made of thickened steel plate and has sufficient structural strength to stably support the weight of the unloading lifting device 200 and the conveyor belt, avoiding deformation due to long-term stress. The top of the support frame plate 523 is provided with a right-angled triangular groove 524 that works with the unloading lifting device 200. Through the cooperation of the right-angled triangular groove 524 and the unloading lifting device 200, the horizontal sliding of the sliding plate 521 is smoothly converted into the vertical lifting of the unloading lifting device 200, realizing the efficient conversion of power transmission.

[0037] The right-angled triangular groove 524 has a rubber pad bonded to its vertical inner wall to buffer the impact force between the unloading lifting device 200 and the inner wall. It can also push the gear rack 522 and the gear 3 540 to re-engage when the gear rack 522 is disengaged by compression.

[0038] In some embodiments of the present invention, reference is made to... Figure 5-9 As shown, the unloading lifting device 200 includes a lifting frame 210 disposed below the conveyor belt and two sets of roller frames 220 slidably mounted on the lifting frame 210. The lifting frame 210 is square in shape and has straight rollers or flat plates installed inside, which can be adjusted according to actual conditions. The upper surface of the straight rollers or flat plates is higher than the upper surface of the lifting frame 210. The roller frames 220 are U-shaped. The roller frames 220 and the lifting frame 210 are connected by the cooperation of guide grooves and guide blocks. The guide blocks are mounted on the lifting frame 210 and slide along the guide grooves. An adjustment space 230 is provided between the inner wall of the 220 and the lower surface of the lifting frame 210, allowing the energy storage device 600 to pass through. The adjustment space 230 can ensure that the energy storage device 600 can pass through smoothly, and can also provide sufficient room for the vertical sliding of the roller frame 220, avoiding interference between the roller frame 220 and the energy storage device 600. At the same time, the adjustment space 230 is reserved for the pad assembly 630 to adjust the initial height of the lifting frame 210, ensuring that the unloading lifting device 200 can adapt to conveyor belts of different thicknesses and improve the versatility of the equipment. A small wheel 240 is rotatably mounted on the outer side of the roller frame 220, which rolls along the hypotenuse of the right-angled triangular groove 524. The roller frame 220 moves smoothly up and down by the rolling of the small wheel 240 along the right-angled triangular groove 524, ensuring the synchronicity and stability of the lifting action of the lifting frame 210. Two limiting plates 250, which are respectively in contact with both ends of the lifting frame 210, are installed on the top of the bracket 100 by bolts or welding. These plates are used to limit the sliding of the lifting frame 210 and can limit the left and right sliding of the lifting frame 210 throughout the process, ensuring that the lifting frame 210 always rises and falls along the preset trajectory, and ensuring the linkage and coordination between the unloading lifting device 200, the plow device 300, and the synchronous adjustment device 500.

[0039] In some embodiments of the present invention, reference is made to... Figure 10 and Figure 11 As shown, the power storage device 600 includes a U-shaped frame plate 610 with its opening facing the synchronous adjustment device 500 and a pad plate 620 passing through the adjustment space 230. The U-shaped frame plate 610 and the pad plate 620 are integrally formed, and the upper surface of the pad plate 620 contacts the lower surface of the lifting frame 210. A pad plate assembly 630 is provided on the pad plate 620 for adjusting the height of the unloading lifting device 200. This assembly is used to adjust the initial height of the unloading lifting device 200 to adapt to conveyor belts of different thicknesses, thereby improving the versatility and adaptability of the equipment. A power storage assembly 640 is provided between the inner wall of the U-shaped frame plate 610 and the end of the synchronous adjustment device 500. This assembly can simultaneously store power when the sliding plate 521 slides horizontally, providing sufficient reset force for the reset of the sliding plate 521 and transmitting an upward auxiliary lifting force to the lifting frame 210 through the pad plate 620 and the pad plate assembly 630.

[0040] In some embodiments of the present invention, reference is made to... Figure 11 As shown, the energy storage component 640 includes an elastic structure 641 fixed on the inner wall of the U-shaped frame plate 610. The elastic structure 641 is preferably made of a high-strength cylindrical helical spring. This spring is made of high-strength spring steel and has the advantages of stable elastic coefficient, strong load-bearing capacity and long fatigue life. It can maintain good elastic performance during long-term repeated compression and reset and is not prone to plastic deformation. A pad 642 is fixedly installed at the end of the elastic structure 641 away from the U-shaped frame plate 610. This pad can stably bear the elastic force of the elastic structure 641 and evenly transmit it to the synchronous adjustment device 500, while avoiding bending deformation of itself under force. In order to reduce the friction between the synchronous adjustment device 500 and the pad 642 when sliding and reduce component wear, multiple balls 643 that rotatably contact the synchronous adjustment device 500 are mounted on the pad 642.

[0041] Among them, the ball bearing 643 makes precise contact with the end of the sliding plate 521 of the synchronous adjustment device 500, which can ensure that the elastic force of the elastic structure 641 is evenly transmitted to the sliding plate 521. This ensures that the sliding plate 521 has sufficient power and smooth operation when it resets, and also provides a stable auxiliary lifting force for the unloading lifting device 200 through the force storage effect of the elastic structure 641.

[0042] In some embodiments of the present invention, reference is made to... Figure 6 and Figure 7 As shown, the pad assembly 630 is a right-angled triangle, which is highly compatible with the inner wall structure of the roller frame 220 and the linkage logic of the synchronous adjustment device 500. This ensures efficient transmission of auxiliary lifting force and height adjustment. The inclined side of the pad assembly 630 has the same inclination angle as the inner wall of the roller frame 220 and is in contact with it. To achieve precise matching between the pad assembly 630 and the roller frame 220 and ensure that the auxiliary lifting force is transmitted evenly and the height adjustment is smooth, the inclined side of the pad assembly 630 and the inclination angle of the inner wall of the roller frame 220 are strictly kept consistent. The inclination angle is determined through mechanical calculation and actual debugging. This ensures that the roller frame 220 fits tightly with the inclined side of the pad assembly 630 when sliding up and down, and avoids problems such as jamming, displacement or uneven force during sliding.

[0043] The inclined side of the pad assembly 630 and the inner wall of the roller frame 220 are always in close contact. On the one hand, this ensures that the pad assembly 630 provides stable support and guidance for the roller frame 220, and assists the roller frame 220 in driving the lifting frame 210 to rise and fall smoothly. On the other hand, by adjusting the installation position of the pad assembly 630 on the pad 620, the initial height of the lifting frame 210 can be changed, thereby adapting to conveyor belts of different thicknesses and specifications, improving the versatility and adaptability of the equipment, and ensuring that the conveyor belt can accurately fit with the plow device 300 during unloading, thus ensuring the unloading effect.

[0044] In some embodiments of the present invention, reference is made to... Figure 3 As shown, it also includes: Several pressing devices 700 are installed on the top of the support 100 and connected to the synchronous adjustment device 500. The pressing devices 700 rotate with the plow device 300 in the initial stage of rotation. In the unloading state, they cooperate with the unloading lifting device 200 to flatten the conveyor belt. In the non-unloading state, they clean the edge of the conveyor belt. The pressing devices 700 are always located above the unloading lifting device 200. When the equipment enters the unloading state, the pressing devices 700 will rotate synchronously to be directly above the unloading lifting device 200. The pressing plate 730 on its top cooperates with the lifting frame 210 of the unloading lifting device 200. The synergistic effect of the two devices limits and flattens the conveyor belt from both the top and bottom, ensuring that the plow device 300 can rotate normally above the conveyor belt and prevent it from being lifted. When the equipment switches to the non-unloading state, the pressing device 700 will rotate in the opposite direction under the reset drive of the synchronous adjustment device 500 and adjust to the tilted state. The end of its pressing plate 730 will make precise contact with the edge of the conveyor belt, and the contact pressure has been precisely adjusted to ensure that the residual material on the edge of the conveyor belt is effectively cleaned without causing wear on the surface of the conveyor belt. As the conveyor belt continues to run.

[0045] Among them, the pressing device 700 is a key component in the equipment that has the dual functions of flattening the conveyor belt and cleaning materials. Its operation rhythm is synchronized with the rotation of the plow device 300. In the initial stage when the plow device 300 starts to rotate counterclockwise and clockwise under the drive of the hydraulic device 400, it will follow the rotation under the power transmission of the synchronization adjustment device 500, adjust its posture in advance, and prepare for the subsequent unloading operation, so as to avoid problems such as conveyor belt wrinkles or material residue caused by the lag in the operation.

[0046] In some embodiments of the present invention, reference is made to... Figure 3 As shown, the pressing device 700 includes a mounting bracket 710 rotatably mounted on the top of the bracket 100, a gear 720 fixedly mounted on the outside of the mounting bracket 710, and a pressing plate 730 mounted on the top of the mounting bracket 710 by bolts or welding. The mounting bracket 710 is made of high-strength alloy steel plate in one piece. Gear 2 720 meshes with gear rack 522 located at the rear end, and drives the lower pressure plate 730 to rotate under the drive of gear rack 522. It can effectively transmit the driving force of gear rack 522, drive the mounting bracket 710 to rotate synchronously, and thus realize the attitude adjustment of lower pressure plate 730. When the unloading lifting device 200 is in the rising state, the lower pressure plate 730 rotates to a longitudinal horizontal state. When the unloading lifting device 200 is in the descending state, the lower pressure plate 730 rotates to an inclined state to clean the edge of the conveyor belt. Because the lower pressure plate 730 has a large transverse diameter, the slight shaking caused by the reciprocating action of the elastic structure 641, the gear rack 522 and the gear 530 will not affect the flattening effect of the conveyor belt. When the plow device 300 rotates to the conveyor belt, it is tangentially set with the lower pressure plate 730 and engages with the lower pressure plate 730. The side of the lower pressure plate 730 near the plow device 300 can have a slight deformation capability to compensate for the impact of shaking.

[0047] The lower pressure plate 730 is designed to maintain the same height as the unloading lifting device 200, preventing the conveyor belt from overlapping with the plow device 300 under the support of the unloading lifting device 200, which would affect the normal rotation and use of the plow device 300.

[0048] The lower pressure plate 730 is made of wear-resistant and tough engineering plastic material, which can not only avoid wear on the surface of the conveyor belt, but also has sufficient structural strength to withstand the force when flattening the conveyor belt and the friction when cleaning materials. The gear 720 and the gear rack 522 at the rear end of the sliding plate 521 are continuously meshed. When the sliding plate 521 of the synchronous adjustment device 500 slides back and forth, the gear rack 522 will drive the gear 720 to rotate synchronously, thereby driving the mounting frame 710 to rotate around its rotation axis, and finally realizing the attitude switching of the lower pressure plate 730.

[0049] The working principle of this embodiment is as follows: When the unloading lifting device 200 rises under the drive of the synchronous adjustment device 500 and enters the unloading state, the sliding plate 521 slides forward, and the gear rack 522 at its rear end moves forward synchronously, driving the second drive gear 720 to rotate in the forward direction, driving the mounting frame 710 to rotate synchronously, so that the lower pressure plate 730 rotates to be directly above the unloading lifting device 200. At this time, the lower pressure plate 730 and the lifting frame 210 cooperate with each other to limit and flatten the conveyor belt from the upper and lower sides, ensuring that the conveyor belt always remains flat and avoiding conveyor belt damage caused by material impact and uneven lifting force. Wrinkles and offsets ensure unloading accuracy; when the unloading lifting device 200 descends and the equipment switches to the non-unloading state, the sliding plate 521 slides backward, the gear rack 522 moves backward in sync, driving the second gear 720 to rotate in the opposite direction, driving the mounting frame 710 to rotate in the opposite direction, so that the lower pressure plate 730 is adjusted to an inclined state, and its end makes precise contact with the edge of the conveyor belt. The contact pressure is precisely adjusted so that it can effectively scrape off the residual material on the edge of the conveyor belt without damaging the surface of the conveyor belt. As the conveyor belt continues to run, it achieves real-time cleaning of the edge of the conveyor belt.

[0050] In some embodiments of the present invention, reference is made to... Figure 2 As shown, the plowshare device 300 includes a plowshare body 310 and a support shaft 320 rotatably mounted on the top of the bracket 100 and fixed to the plowshare body 310. The support shaft 320 is made of high-strength alloy steel, which can stably bear the weight of the plowshare body 310 and the impact load of the material during unloading, avoiding bending deformation due to long-term stress. It enables the plowshare body 310 to rotate synchronously clockwise and counterclockwise around the support shaft 320, achieving precise adjustment of the unloading posture. A cleaning pad 330 is bonded to the bottom of the plowshare body 310, which contacts the conveyor belt in the unloading state. In the unloading state, the cleaning pad 330 is in close contact with the surface of the conveyor belt, thus... The surface can enhance the sealing between the plow body 310 and the conveyor belt, prevent material leakage from the gap, and improve the unloading effect. On the other hand, it can effectively buffer the friction between the plow body 310 and the conveyor belt, reduce the wear of the plow body 310 on the surface of the conveyor belt, protect the conveyor belt, and extend the service life of the conveyor belt. The rear side of the plow body 310 is fixedly installed with a hinge frame 340 that is hinged to the hydraulic device 400. The hinge frame 340 ensures that the extension and retraction of the hydraulic device 400 can be smoothly transmitted to the plow body 310, driving the plow body 310 to rotate smoothly around the support shaft 320, realizing the precise switching between unloading and non-unloading states.

[0051] Among them, the plow body 310 has a wedge-shaped structure. Its tilt angle has been precisely calculated and actually adjusted. It can ensure that the material is smoothly diverted and unloaded to one side under the conveying power of the conveyor belt, and can also avoid material accumulation and jamming, thus improving unloading efficiency.

[0052] The cleaning pad 330 uses materials such as MXene / graphene oxide nanocomposite coating to reduce the coefficient of friction, achieving a coefficient of friction as low as 0.065 under high contact pressure (1GPa), and combining high wear resistance and environmental adaptability; and the bottom of the lower pressure plate 730 and the upper surface of the flat plate on which the support frame 210 is mounted are both bonded with the same material as the cleaning pad 330.

[0053] The working method of this invention: Unloading state: The hydraulic device 400 is activated, the hydraulic cylinder extends, pushing the articulated frame 340, causing the plow body 310 to rotate counterclockwise around the support shaft 320. Simultaneously, the rotation of the support shaft 320 drives the gear 530 fixed to it to rotate. The gear 530 meshes with the gear rack 522 at the front end of the sliding plate 521, driving the sliding plate 521 to slide forward along the track 510. As the sliding plate 521 slides, it also moves the support frame plate 523 and the rear gear rack 522, causing the right-angled triangular groove 524 to move relative to the small wheel 24. The movement of the 0-axis causes the small wheel 240 to rise along the inclined surface of the right-angled triangular groove 524, lifting the lifting frame 210 and the corresponding area of ​​the conveyor belt. The height of the lifting is limited by the lower pressure plate 730, which flattens the conveyor belt to facilitate the entry of the subsequent plow body 310. When the support frame plate 523 slides, it will also squeeze the elastic structure 641, causing the elastic structure 641 to compress and store force. When the rear gear rack 522 moves, it will drive the second gear 720 to rotate, which in turn causes the second gear 720 to drive the lower pressure plate 730 to rotate to a horizontal state through the mounting frame 710. After the lifting frame 210 rises to the corresponding height and the lower pressure plate 730 rotates to the corresponding state, the gear 530 disengages from the gear rack 522 at the front end of the sliding plate 521, so that the plow body 310 rotates to the corresponding angle and enters the working state with minimal disturbance to the lifting frame 210 and the lower pressure plate 730. Under the action of the plow body 310, the material conveyed by the conveyor belt is unloaded to one side, completing the unloading operation.

[0054] In non-unloading state: Control hydraulic device 400, hydraulic cylinder retracts, pulling articulated frame 340 to drive plow body 310 to rotate counterclockwise around support shaft 320. During the initial rotation of support shaft 320 and plow body 310, rack 522, pushed by elastic structure 641, meshes with gear one 530, causing gear one 530 to drive support frame plate 523 to reset and gear two 720 to rotate in the opposite direction via rack 522. Tin wheel 240 rolls downwards along the hypotenuse of right-angled triangular groove 524, driving the roller... The wheel frame 220 moves downward, the lifting frame 210 descends, and drives the lower pressure plate 730 to rotate to an inclined state and contact the edge of the conveyor belt. As the conveyor belt runs, it cleans up the residual material on the edge of the conveyor belt. Since the vertical inner wall of the right-angle triangular groove 524 is bonded with a rubber pad, the compression of the rubber pad can temporarily disengage the gear rack 522 from the gear one 530 and the gear two 720, providing conditions for the plow body 310 to continue rotating until the plow body 310 disengages from the conveyor belt and rotates to the initial position.
