Description

Technical Field

[0001] This application relates to the technical field of conveyor pushing devices, and in particular to a pushing assembly for a hopper conveyor line. Background Technology

[0002] Currently, the pushing components used in bucket conveyor lines are usually installed on one side or above the conveyor line. The pusher is driven by a drive mechanism to move back and forth, pushing the bucket forward to the next process, thus realizing the automated flow of the bucket. With the continuous improvement of the automation level of industrial production, higher requirements are placed on the pushing efficiency, pushing accuracy, and stability of the bucket during the pushing process of the bucket conveyor line.

[0003] Regarding the aforementioned related technologies, for example, an automatic feeding push rod mechanism with authorization announcement number CN224118225U includes a frame, a pushing module, and a push rod connected to the pushing module. The pushing module includes a motor, a driving wheel, a driven wheel, and a transmission belt. The driving wheel and the driven wheel are respectively installed at opposite ends of the frame and connected by the transmission belt. The motor is connected to the driving wheel, and the push rod is connected to the transmission belt. This feeding mechanism drives the push rod to reciprocate by the motor driving the transmission belt, thereby realizing the automatic feeding of materials.

[0004] The position, height, and stroke of the push rod or push plate in existing pusher assemblies are usually fixed, making it difficult to adapt to different sizes of material buckets. At the same time, during the pushing process, the material buckets move only with the support of the conveyor line itself, lacking effective support and restraint for the bottom of the material buckets. Especially for longitudinally inverted cylindrical material buckets, they are prone to rolling or shifting during the pushing process, resulting in inaccurate pushing positions. In addition, existing support structures are mostly fixed, making it difficult to flexibly adjust the support width and position according to changes in the diameter of the material buckets, resulting in poor versatility. Summary of the Invention

[0005] The purpose of this application is to provide a pushing assembly for a hopper conveyor line to solve the problems in the prior art.

[0006] The material pushing component for a material bucket conveying line provided in this application adopts the following technical solution: it includes a supporting profile, a synchronous conveyor belt and a material pushing structure. The supporting profile is externally connected to the synchronous conveyor belt, and the synchronous conveyor belt is externally connected to the material pushing structure. The material pushing structure pushes the material bucket with the synchronous conveyor belt. It also includes an adjustable support device installed on the outside of the material pushing end of the material pushing structure.

[0007] By adopting the above technical solution, namely, using the supporting profile to provide the installation foundation for the whole, and using the synchronous conveyor belt as the active transmission component to drive the pushing structure to move back and forth along the conveying direction, thereby realizing the continuous pushing of the material bucket; the adjustable support device is installed on the outside of the pushing end of the pushing structure, which can adaptively adjust the support range according to the size and position of the material bucket, improve the stability of the material bucket during the pushing process, avoid the material bucket from tipping over or deviating, and solve the problems of poor adaptability and unstable pushing of the existing pushing components.

[0008] Preferably, the adjustable support device includes a base plate, with clamps installed on both sides of the upper end of the base plate, and the base plate is connected to the pushing end of the pushing structure through the clamps on both sides of the upper end. A first motor is installed at the lower end of one clamp, and a transmission rod is connected to the output end of the first motor. The transmission rod is externally connected to the support structure, and the support structure is installed on the three sides of the upper end of the base plate.

[0009] By adopting the above technical solution, the adjustable support device can be quickly disassembled and connected to the pushing end of the pushing structure through the base plate and clamps, which is convenient for maintenance and replacement. The first motor serves as the drive source and transmits power to the support structure through the transmission rod, so that the support structure can adjust the support range according to the actual position of the material bucket, thereby ensuring that the material bucket can be effectively supported during the pushing process and improving the versatility and reliability of the pushing component.

[0010] Preferably, the pushing structure includes a connecting plate, which is internally connected to the upper end of the synchronous conveyor belt via fasteners. Side frames are locked on both sides of the connecting plate, and the upper and lower ends of the side frames are symmetrically equipped with limiting wheels that abut against the outer shell. The left and right ends of the front side of the connecting plate are rotatably connected to first rotating plates, and a locking rod is locked between the front ends of the two first rotating plates. A limiting plate is locked on the outside of the first rotating plate, and the upper end of the limiting plate abuts against a limiting shaft that locks against the outer shell. The outer side of the first rotating plate is connected to one output end of a bidirectional cylinder, and the other output end of the bidirectional cylinder is connected to a second rotating plate. The second rotating plate is rotatably installed on the left and right ends of the rear side of the connecting plate. Rotating rods are rotatably connected between the left and right first rotating plates and the second rotating plate, and a pushing rod is connected to the rear side of the rotating rod. A pushing plate for pushing the material bucket is provided on the rear side of the pushing rod.

[0011] By adopting the above technical solution, the material pushing structure is fixedly connected to the synchronous conveyor belt through the connecting plate, and moves as a whole with the movement of the conveyor belt; the limiting wheel on the side frame abuts against the outer shell, playing a guiding and limiting role, ensuring the smooth operation of the material pushing structure; the bidirectional cylinder drives the first rotating plate and the second rotating plate to rotate synchronously, so that the rotating rod and the pushing rod are raised to the pushing position, and the pushing plate connected to the back of the pushing rod will be transported with the synchronous conveyor belt to realize the forward pushing and conveying of the material bucket.

[0012] Preferably, the supporting structure includes a rotating cylinder connected to the outside of the transmission rod, and both the front and rear sides of the rotating cylinder are rotatably connected to the side blocks. Guide rods for sliding guidance are connected between the four corners of the front and rear side blocks. The rotating cylinder and the guide rods are externally connected to the adjustment assembly, and a support component is installed on the outside of the adjustment assembly. An unfolding component is provided inside the upper end of the support component.

[0013] By adopting the above technical solution, the supporting structure receives the rotational power of the transmission rod through the rotating drum, and under the support and guidance of the side blocks and guide rods, the adjusting component slides axially along the guide rod, thereby driving the supporting component to adjust its position above the base plate; the unfolding component is used to adjust the supporting width at the upper end of the supporting component to adapt to material barrels of different diameters, thereby achieving multi-dimensional and multi-directional supporting adjustment during the material pushing process, effectively preventing the material barrel from tipping over during pushing.

[0014] Preferably, the adjusting component includes a transmission groove, which is opened on the outside of the rotating drum, and a connecting shaft is opened inside the transmission groove. The connecting shaft is externally connected to the slider. The slider has connecting holes on all four sides, and a sleeve is installed inside each connecting hole. The sleeve is slidably connected to the outside of the guide rod, and the outside of the slider is connected to the support member.

[0015] By adopting the above technical solution, the adjusting component utilizes the cooperation between the connecting shaft and the slider inside the transmission groove. When the drum rotates, the slider moves along the trajectory of the transmission groove under the drive of the connecting shaft. At the same time, the sliding cooperation between the sleeve and the guide rod ensures that the slider can only slide linearly along the axial direction of the guide rod. Thus, the rotational motion of the drum is accurately converted into the linear displacement of the slider, thereby driving the support component to move smoothly and achieving precise adjustment of the support position.

[0016] Preferably, the support includes a locking shaft, which is fixed to the left and right sides of the slider, and a bracket is locked to the outside of the locking shaft on both sides. The top of the bracket is connected to a support plate, and an unfolding component is provided inside the upper end of the support plate.

[0017] By adopting the above technical solution, the support component is fixed to both sides of the slider by the locking shaft and moves synchronously with the slider; the top support plate of the support directly contacts the bottom of the material barrel and provides a support surface; the unfolding component is built into the upper part of the support plate, and the support width of the support plate can be adjusted without increasing the external space occupation, thus taking into account both structural compactness and support adaptability.

[0018] Preferably, the unfolding assembly includes a protective shell, which is connected to the lower middle part of the support plate. A second motor is provided on the left side inside the protective shell. The output end of the second motor is connected to a bidirectional screw, and a guide rod is provided opposite to the upper end of the bidirectional screw. Both sides of the bidirectional screw and the guide rod are connected to transmission bars. The upper end of the transmission bar is connected to a first connecting arm. One end of the first connecting arm is movably inserted into the guide groove, and the other end of the first connecting arm is rotatably connected to a rotating plate. The guide groove is opened on the rear wall inside the protective shell. The rotating plate is rotatably connected to the upper end inside the protective shell, and a second connecting arm is connected to the other side of the rotating plate. The upper end of the second connecting arm is rotatably connected to a support bar, and the support bar is rotatably installed inside the support plate. The support bar is covered with an anti-slip sleeve.

[0019] By adopting the above technical solution, the unfolding assembly is driven by a second motor to rotate a bidirectional screw, causing the two transmission bars on both sides to move closer or further apart along the guide rod; the transmission bars drive the rotating plate to rotate through the first connecting arm, and the rotating plate then pushes the support bar to unfold outward or retract inward relative to the support plate through the second connecting arm, thereby achieving rapid adjustment of the support width; the guide groove constrains the movement trajectory of the first connecting arm to ensure the synchronicity and consistency of the unfolding actions on the left and right sides; the anti-slip sleeve increases the friction between the support bar and the bottom of the material barrel, preventing the material barrel from sliding during the pushing process, and further improving the stability and safety of the pushing process.

[0020] Preferably, the transmission grooves are opened sequentially from the middle of the rotating drum to the front and rear sides, and the front and rear transmission grooves are gradually inclined as curved grooves.

[0021] By adopting the above technical solution, namely, the transmission groove is opened sequentially from the middle to both sides and gradually inclined in a curve, multiple sliders on the front and rear sides can slide synchronously in opposite directions along the guide rod when the drum rotates. This enables multiple supporting parts on the front and rear sides to move towards each other or away from each other. While ensuring the synchronization of adjustment, the supporting position can be symmetrically adjusted according to the actual size of the material barrel, thereby improving the adjustment efficiency and supporting accuracy.

[0022] Preferably, the bracket and the support plate form a portal frame structure, and the top support position of the support plate and the material pushing position of the push plate are at the same horizontal level.

[0023] By adopting the above technical solution, the portal frame structure formed by the bracket and the support plate has high structural strength and bending stiffness, which can withstand the gravity and inertial force generated during the pushing process of the material bucket; at the same time, the top support position of the support plate and the pushing position of the push plate are at the same level, so that when the material bucket is pushed, the supporting force of the support plate on the bottom and the pushing force of the push plate on the side are in the same horizontal plane, avoiding the generation of additional overturning moment and ensuring that the material bucket always maintains a stable posture during the pushing process.

[0024] Preferably, a ball bearing is integrally embedded at the bottom of the transmission bar, and a vertical hollow groove is integrally formed at the upper end of the transmission bar, which is connected to the external transmission of one side of the first connecting arm.

[0025] By adopting the above technical solution, the ball bearings embedded at the bottom of the transmission bar can reduce the sliding friction between the transmission bar and the bottom of the protective shell, making the transmission bar move more smoothly under the bidirectional screw drive, reducing energy loss and wear; the vertical hollow groove opened at the upper end of the transmission bar is connected to the external transmission on one side of the first connecting arm, so that while the first connecting arm moves with the transmission bar, it can also generate relative sliding in the vertical hollow groove, thereby converting the horizontal linear motion of the transmission bar into the swing motion of the first connecting arm, realizing the conversion of the direction of motion.

[0026] Preferably, the rotating plate is arranged in the shape of a triangular plate, and the triangular part of the rotating plate is rotatably connected to the protective shell, the first connecting arm and the second connecting arm respectively.

[0027] By adopting the above technical solution, namely, the rotating plate adopts a triangular plate structure, with its three corners serving as the fixed rotation fulcrum with the protective shell, the power input connection point with the first connecting arm, and the power output connection point with the second connecting arm, respectively, the stability of the triangular structure and the lever principle are utilized to amplify the small displacement input by the first connecting arm into a large displacement output by the second connecting arm, thereby doubling the stroke of the support bar when it unfolds or retracts. At the same time, the triangular plate structure itself has good rigidity and is not easily deformed, which can ensure the transmission accuracy and reliability under long-term use.

[0028] In summary, this application includes the following beneficial technical effects: 1. This application employs a material pushing structure, which is fixedly connected to a synchronous conveyor belt via a connecting plate, allowing the entire structure to move with the conveyor belt. Limiting wheels on the side frame abut against the outer casing, providing guidance and limiting to ensure smooth operation of the material pushing structure. A bidirectional cylinder drives the first and second rotating plates to rotate counter-clockwise synchronously, raising the rotating rod and pushing rod to the pushing position. The pushing plate, positioned behind the pushing rod, is then conveyed by the synchronous conveyor belt, achieving forward pushing of the material bucket. The limiting plate abuts against limiting shafts locked inside the outer casing on both sides. The highest point of the upper surface of the limiting plate abuts against the limiting shafts, achieving mechanical limiting to determine whether the material bucket has been pushed forward to the designated position. A control signal is triggered to drive the bidirectional cylinder in the opposite direction, causing the pushing rod and pushing plate to fall back to their initial unlifted state. This ensures the accuracy and reliability of each pushing action, achieving stable, precise, and efficient pushing and conveying.

[0029] 2. This application incorporates an adjustable support device that allows for quick assembly and disassembly of the material pushing end of the pushing structure via a base plate and clamps, facilitating maintenance and replacement. A first motor serves as the drive source, transmitting power to the support structure via a transmission rod. This allows the support structure to adjust its support range according to the actual position of the material bucket, ensuring effective support for the bucket during the pushing process. Simultaneously, the top support position of the support plate is at the same level as the pushing position of the push plate, ensuring that the supporting force from the support plate on the bottom and the pushing force from the push plate on the sides of the bucket are within the same horizontal plane during pushing. This avoids additional overturning moments, ensuring the stability and safety of the bucket pushing process and improving the versatility and reliability of the pushing assembly.

[0030] 3. This application utilizes an adjustment component and a support component. The adjustment component employs the connection between the connecting shaft and the slider inside the transmission groove. When the drum rotates, the slider moves along the trajectory of the transmission groove under the drive of the connecting shaft. Simultaneously, the sliding cooperation between the sleeve and the guide rod ensures that the slider can only slide linearly along the axial direction of the guide rod. This precisely converts the rotational motion of the drum into the linear displacement of the slider, driving the support component to move smoothly and achieving precise adjustment of the support position. The transmission groove adopts a layout that opens sequentially from the middle to both sides and gradually slopes in a curve. This allows multiple sliders on the front and rear sides to slide synchronously in opposite directions along the guide rod when the drum rotates. This enables multiple support components on the front and rear sides to move towards each other or away from each other, allowing the support position to be symmetrically adjusted according to the actual size of the drum, improving adjustment efficiency and support accuracy.

[0031] 4. This application incorporates an unfolding component. Before the push plate rises and contacts the material bucket, the unfolding component is pre-adaptively adjusted according to the actual bottom dimensions of the material bucket on site. If no adjustment is needed, each support bar is completely flat and built into the support plate, which provides planar auxiliary support. If adjustment is required, the second motor drives the bidirectional screw to rotate, bringing the two transmission bars closer together. The first connecting arm drives the triangular rotating plate to rotate, and the second connecting arm pushes the support bar upward to a V-shaped support state, forming a V-shaped support groove that is low in the middle and high at both ends. This groove perfectly fits the bottom arc surface of the vertically inverted cylindrical material bucket, achieving automatic centering. The anti-slip sleeve increases friction to prevent slippage. After reverse drive, the support bar can be restored to a flat and retracted position, balancing structural compactness and support adaptability. Attached Figure Description

[0034] The following is in conjunction with the appendix Figure 1 -Appendix Figure 7 This application will be described in further detail below.

[0035] A pusher assembly for a hopper conveyor line, as shown in the reference. Figures 1-2 It includes a support profile 1, a synchronous conveyor belt 2 and a pushing structure. The support profile 1 is externally connected to the synchronous conveyor belt 2, and the synchronous conveyor belt 2 is externally connected to the pushing structure. The pushing structure pushes the material bucket along with the synchronous conveyor belt 2. It also includes an adjustable support device 15 installed on the outside of the pushing end of the pushing structure.

[0036] Specifically, the supporting profile 1 provides the installation foundation for the whole, and the synchronous conveyor belt 2 acts as the active transmission component to drive the pushing structure to move back and forth along the conveying direction, thereby realizing the continuous pushing of the material bucket; the adjustable support device 15 is installed on the outside of the pushing end of the pushing structure, which can adaptively adjust the support range according to the size and position of the material bucket, improve the stability of the material bucket during the pushing process, avoid the material bucket from tipping over or shifting, and solve the problems of poor adaptability and unstable pushing of the existing pushing components.

[0037] Furthermore, the pushing structure includes a connecting plate 3, which is internally connected to the upper end of the synchronous conveyor belt 2 via fasteners, allowing it to move back and forth with the synchronous conveyor belt 2. Side frames 4 are locked to both sides of the connecting plate 3, and symmetrically mounted at both ends of the side frames 4 are limit wheels 5 that abut against the outer casing. First rotating plates 6 are rotatably connected to both the left and right ends of the front side of the connecting plate 3, and locking rods 7 are locked between the front sides of the two first rotating plates 6. Limit plates 8 are locked to the outside of the two first rotating plates 6, and the upper surface of the limit plates 8 gradually rises from front to back, with the upper surface of the limit plates 8 abutting against and locking against the outer casing. When the limiting shaft 9, i.e. the limiting plate 8, moves forward with the synchronous conveyor belt 2 to push the material bucket forward, the limiting signal is triggered by the abutment of the limiting shaft 9 at the inclined position of the upper surface. The outer side of the first rotating plate 6 on both sides is connected to the front output end of the bidirectional cylinder 10, and the rear output end of the bidirectional cylinder 10 is connected to the second rotating plate 11. The second rotating plate 11 is rotatably installed on the left and right ends of the rear side of the connecting plate 3. The left and right first rotating plates 6 and the second rotating plate 11 are connected to the rotating rod 12 through the shaft rotation, and the rear side of the rotating rod 12 is longitudinally connected to the push rod 13. The push plate 14 for pushing the material bucket is provided on the rear side of the push rod 13.

[0038] Specifically, the pushing structure is fixedly connected to the synchronous conveyor belt 2 via the connecting plate 3, and moves as a whole with the conveyor belt; the limiting wheel 5 on the side frame 4 abuts against the outer shell, playing a guiding and limiting role, ensuring the smooth operation of the pushing structure; the bidirectional cylinder 10 drives the first rotating plate 6 and the second rotating plate 11 to rotate synchronously, so that the rotating rod 12 and the pushing rod 13 are raised to the pushing position, and thus the pushing plate 14 connected to the rear side of the pushing rod 13 will be transported with the synchronous conveyor belt 2 to realize the forward pushing and conveying of the material bucket.

[0039] Reference Figure 3 The adjustable support device 15 includes a base plate 151. Clamps 152 are installed on both the front and rear sides of the upper end of the base plate 151. The base plate 151 is locked to the outside of the push rod 13 by the clamps 152 on the front and rear sides of the upper end. A first motor 153 is installed on the outside of the lower end of the front clamp 152. The output end of the first motor 153 is connected to a transmission rod 154. The transmission rod 154 is longitudinally arranged on the upper end of the base plate 151. The outside of the transmission rod 154 is connected to the support structure 155. The support structure 155 is installed on the three sides of the upper end of the base plate 151.

[0040] Specifically, the adjustable support device 15 can be quickly connected and disassembled with the pushing end of the pushing structure through the base plate 151 and the clamp 152, which facilitates maintenance and replacement; the first motor 153 serves as the drive source and transmits power to the support structure 155 through the transmission rod 154, so that the support structure 155 can adjust the support range according to the actual position of the material bucket, thereby ensuring that the material bucket can be effectively supported during the pushing process and improving the versatility and reliability of the pushing component.

[0041] Reference Figure 4 The supporting structure 155 includes a rotating cylinder 1551, which is connected to the three sides of the outer end of the transmission rod 154. The front and rear ends of each rotating cylinder 1551 are rotatably connected to the side block 1552, and the bottom of the front and rear side blocks 1552 are locked to the base plate 151. The four corners of the front and rear side blocks 1552 are longitudinally connected with guide rods 1553 for sliding guidance. The rotating cylinder 1551 and the guide rods 1553 are externally connected to the adjustment assembly 1554. The adjustment assembly 1554 is externally mounted with a support member 1555, and the upper end of the support member 1555 is internally provided with an unfolding assembly 1556.

[0042] Specifically, the support structure 155 receives the rotational power of the transmission rod 154 through the rotating drum 1551, and under the support and guidance of the side block 1552 and the guide rod 1553, the adjustment component 1554 slides axially along the guide rod 1553, thereby driving the support member 1555 to adjust its position above the base plate 151; the unfolding component 1556 is used to adjust the support width at the upper end of the support member 1555 to adapt to material barrels of different diameters, thereby achieving multi-dimensional and multi-directional support adjustment during the material pushing process, effectively preventing the material barrel from tipping over during pushing.

[0043] Reference Figure 5 The adjustment component 1554 includes a transmission groove 15541, which is located on the outside of the rotating drum 1551. A connecting shaft 15542 is provided inside the transmission groove 15541. The outside of the connecting shaft 15542 is connected to the slider 15543. There are eight connecting shafts 15542 and eight sliders 15543. Each slider 15543 has a connecting hole 15544 on all four sides. A sleeve 15545 is installed inside each connecting hole 15544. Each sleeve 15545 is slidably connected to the outside of each guide rod 1553. Each slider 15543 has an adjustable support member 1555 connected to its outer end.

[0044] Specifically, the adjusting component 1554 utilizes the cooperation between the connecting shaft 15542 and the slider 15543 inside the transmission groove 15541. When the rotating drum 1551 rotates, the slider 15543 moves along the trajectory of the transmission groove 15541 under the drive of the connecting shaft 15542. At the same time, the sliding cooperation between the sleeve 15545 and the guide rod 1553 ensures that the slider 15543 can only slide linearly along the axial direction of the guide rod 1553. Thus, the rotational motion of the rotating drum 1551 is accurately converted into the linear displacement of the slider 15543, thereby driving the support component 1555 to move smoothly and achieving precise adjustment of the support position.

[0045] Furthermore, the transmission groove 15541 is opened sequentially from the middle of the rotating cylinder 1551 to the front and rear sides, and the front and rear transmission grooves 15541 are opened gradually at an incline as curved grooves.

[0046] Specifically, the transmission groove 15541 adopts a layout that opens sequentially from the middle to both sides and gradually slopes in a curve. This allows multiple sliders 15543 on the front and rear sides to slide synchronously in opposite directions along the guide rod 1553 when the rotating drum 1551 rotates. This enables multiple support members 1555 on the front and rear sides to move towards each other or away from each other. While ensuring the synchronization of adjustment, the support position can be symmetrically adjusted according to the actual size of the material barrel, thereby improving the adjustment efficiency and support accuracy.

[0047] Reference Figure 6 The support component 1555 includes a locking shaft 15551, which is fixed to the left and right sides of the slider 15543. Both sides of the locking shaft 15551 are locked with brackets 15552. The top of the brackets 15552 on both sides are connected to the support plate 15553. The upper end of the support plate 15553 is provided with an unfolding component 1556. The support plate 15553 is arranged in a horizontal strip shape.

[0048] Specifically, the support component 1555 fixes the bracket 15552 to both sides of the slider 15543 through the locking shaft 15551, and moves synchronously with the slider 15543; the top support plate 15553 of the bracket 15552 directly contacts the bottom of the material barrel and provides a support surface; the unfolding component 1556 is built into the upper part of the support plate 15553, which can adjust the support width of the support plate 15553 without increasing the external space occupation, thus taking into account both structural compactness and support adaptability.

[0049] Furthermore, the bracket 15552 and the support plate 15553 form a portal frame structure, and the top support position of the support plate 15553 and the material pushing position of the push plate 14 are at the same horizontal level.

[0050] Specifically, the portal frame structure formed by the bracket 15552 and the support plate 15553 has high structural strength and bending stiffness, and can withstand the gravity and inertial force generated during the pushing process of the material bucket; at the same time, the top support position of the support plate 15553 and the pushing position of the push plate 14 are at the same level, so that when the material bucket is pushed, the bottom of the support plate 15553 and the side of the push plate 14 are in the same horizontal plane, avoiding the generation of additional overturning moment and ensuring that the material bucket always maintains a stable posture during the pushing process.

[0051] Reference Figure 7The unfolding assembly 1556 includes a protective shell 15561, which is connected to the lower middle part of the support plate 15553. A second motor 15562 is located on the left side inside the protective shell 15561. A bidirectional screw 15563 is connected to the output end of the second motor 15562, and a guide rod 15564 is located opposite the upper end of the bidirectional screw 15563. Transmission bars 15565 are connected to the outer sides of both the bidirectional screw 15563 and the guide rod 15564, and are threaded to the outer side of the bidirectional screw 15563. The transmission bars 15565 are slidably connected to the outer side of the guide rod 15564. A first connecting arm 15566 is connected to the upper end of each transmission bar 15565, and one end of each first connecting arm 15566 has a detachable rear side. The first connecting arm 15566 is inserted into the guide groove 15567, and the other end of the first connecting arm 15566 is rotatably connected to the rotating plate 15568. The guide groove 15567 is opened on both sides of the inner rear wall of the protective shell 15561, and the two guide grooves 15567 are opened in opposite inclined directions to guide the two first connecting arms 15566 in a stable push-pull transmission state. The two rotating plates 15568 are rotatably connected to the upper end of the inner shell 15561, and the other side of the two rotating plates 15568 is connected to the second connecting arm 15569. The upper end of the two second connecting arms 15569 is rotatably connected to the support bar 155610, and the support bar 155610 is rotatably installed on the left and right sides inside the support plate 15553. The two support bars 155610 are covered with anti-slip sleeves 155611.

[0052] Specifically, the unfolding component 1556 drives the bidirectional screw 15563 to rotate via the second motor 15562, causing the two transmission bars 15565 to move closer or further apart along the guide rod 15564. The transmission bars 15565 drive the rotating plate 15568 to rotate via the first connecting arm 15566, and the rotating plate 15568 then pushes the support bar 155610 to unfold outward or retract inward relative to the support plate 15553 via the second connecting arm 15569, thereby achieving rapid adjustment of the support width. The guide groove 15567 constrains the movement trajectory of the first connecting arm 15566 to ensure the synchronicity and consistency of the unfolding actions on the left and right sides. The anti-slip sleeve 155611 increases the friction between the support bar 155610 and the bottom of the material barrel, preventing the material barrel from sliding during the pushing process, and further improving the stability and safety of the pushing process.

[0053] Furthermore, a ball bearing is integrally embedded at the bottom of the transmission bar 15565, and a vertical hollow groove is integrally formed at the upper end of the transmission bar 15565, which is connected to the external transmission of one side of the first connecting arm 15566.

[0054] Specifically, the ball bearings embedded at the bottom of the transmission bar 15565 can reduce the sliding friction between the transmission bar 15565 and the bottom of the protective shell 15561, making the transmission bar 15565 move more smoothly under the drive of the bidirectional screw 15563, reducing energy loss and wear; the vertical hollow groove opened at the upper end of the transmission bar 15565 is externally connected to one side of the first connecting arm 15566, so that while the first connecting arm 15566 moves with the transmission bar 15565, it can also slide relative to the first connecting arm 15566 in the vertical hollow groove, thereby converting the horizontal linear motion of the transmission bar 15565 into the swing motion of the first connecting arm 15566, realizing the conversion of the direction of motion.

[0055] Furthermore, the rotating plate 15568 is arranged in the shape of a triangular plate, and the triangle of the rotating plate 15568 is rotatably connected to the protective shell 15561, the first connecting arm 15566 and the second connecting arm 15569 respectively.

[0056] Specifically, the rotating plate 15568 adopts a triangular plate structure, with its three corners serving as the fixed rotation fulcrum with the protective shell 15561, the power input connection point with the first connecting arm 15566, and the power output connection point with the second connecting arm 15569, respectively. Utilizing the stability of the triangular structure and the lever principle, the small displacement input by the first connecting arm 15566 is amplified into a large displacement output by the second connecting arm 15569, thereby doubling the stroke of the support bar 155610 when it unfolds or retracts. At the same time, the triangular plate structure itself has good rigidity and is not easily deformed, which can ensure the transmission accuracy and reliability under long-term use.

[0057] The working principle of this application is as follows: First, the pushing structure moves backward along with the synchronous conveyor belt 2 to the corresponding position at the bottom rear of the material bin to be pushed. During this process, the bidirectional cylinder 10 is not activated, the first rotating plate 6 and the second rotating plate 11 maintain the initial angle, and the rotating rod 12, the pushing rod 13 and the pushing plate 14 are all in a standby state without being raised, ensuring that the pushing structure can move smoothly to the rear of the material bin without interfering with the material bin. Before the material pushing structure moves into position and the bidirectional cylinder 10 drives the push plate 14 to rise and contact the material bucket, the unfolding assembly 1556 can be pre-adaptively adjusted according to the actual bottom size of the material bucket on site. Specifically: If the current size of the material bucket does not require adjustment of the support width, the unfolding component 1556 remains stably stored, and each support bar 155610 is completely flat and built into the support plate 15553 of the support component 1555, without any unfolding action; at this time, the horizontally elongated support plate 15553 serves as the main support component, and its upper support surface is flat, providing basic planar auxiliary support for the bottom of the material bucket, which is suitable for material buckets with smaller diameters or no additional limiting; If adjustments are needed based on the size of the hopper, the second motor 15562 starts, driving the bidirectional screw 15563 to rotate. This causes the two transmission bars 15565 to move closer together along the guide rod 15564. The two transmission bars 15565 then engage with the vertical hollow groove at the top and the guide grooves 15567 on both sides of the inner rear wall of the protective shell 15561. The guide grooves 15567 are inclined in opposite directions to guide the first connecting arms 15566 to a stable push-pull transmission state. This causes the first connecting arms 15566 to rotate the triangular rotating plate 15568. The rotating plate 15568 then pushes the support bar 155610 relative to the support plate 15553 through the second connecting arm 15569, causing the support bars 155610 to rotate from... Initially flat and level, the material gradually tilts upwards with the linkage of the mechanism, eventually adjusting to a V-shaped support state with an adjustable opening size. This forms a V-shaped support groove that is low in the middle and high at both ends. This V-shaped support groove can perfectly fit the bottom arc surface of the vertically inverted cylindrical material barrel. The V-shaped slope achieves automatic centering, firmly embedding the material barrel into the groove and effectively preventing the material barrel from rolling left and right during the pushing process. At the same time, by controlling the flipping angle of the two side support bars 155610, the size of the V-shaped opening can be flexibly adjusted to accommodate material barrels of different diameters. In this unfolded state, the support plate 15553 serves as the mounting base for the support bars 155610 and does not directly contact the bottom of the material barrel. Only the V-shaped support surface formed by the two upward-flipping support bars 155610 provides auxiliary support for the material barrel. After the adjustment of the unfolding component 1556 is completed, the bidirectional cylinder 10 starts to run. Its two output ends drive the first rotating plate 6 and the second rotating plate 11 to rotate counterclockwise in sync. In this way, the first rotating plate 6 and the second rotating plate 11 will drive the push rod 13 to rise upward through the rotating rod 12, so that the push plate 14 rises to the push position that abuts against the rear side of the material barrel. At the same time, the limiting plate 8 locked outside the first rotating plate 6 changes its angle as the rotating plate rotates. When the push plate 14 is raised to abut against the rear of the material bucket, the synchronous conveyor belt 2 starts running again, driving the connecting plate 3 and the entire pushing structure fixed thereto to move forward along the support profile 1. During this process, the limiting wheel 5 on the side frame 4 rolls against the outer shell, which guides and limits the forward movement of the pushing structure, ensuring that the pushing structure runs smoothly. The push plate 14 moves forward with the entire pushing structure, continuously pushing the material bucket forward to the designated transmission position. When the pushing structure moves backward and is lifted, the adjustable support device 15 simultaneously makes adaptive adjustments. Specifically, the first motor 153 drives the rotating drum 1551 to rotate through the transmission rod 154. The transmission groove 15541 on the outer side of the rotating drum 1551 drives the slider 15543 to slide axially along the guide rod 1553 through the connecting shaft 15542, thereby driving the support members 1555 on each side to adjust their position in the front and back directions above the bottom plate 151, so that the support plate 15553 moves to a support position that is compatible with the bottom of the material barrel. At this time, the support method is as follows, depending on the different states of the unfolding component 1556: if the unfolding component 1556 is not running, the support plate 15553 will support the material barrel. The upper plane provides auxiliary support to the bottom of the material bucket. If the unfolding component 1556 is in operation, the support bars 155610 that flip upward on both sides together form a V-shaped support groove to limit and support the material bucket. The anti-slip sleeves 155611 on the outside of the support bars 155610 can increase the friction with the material bucket and prevent slippage. At the same time, the top support position of the support plate 15553 and the pushing position of the push plate 14 are at the same level, so that the support force of the support plate 15553 on the bottom of the material bucket and the pushing force of the push plate 14 on the side are in the same horizontal plane during the pushing process, avoiding the generation of additional overturning moment and ensuring the stability and safety of the material bucket pushing. When the device moves to the designated transmission position, the limiting plate 8 will come into contact with the limiting shafts 9 locked inside the outer housing on both sides. The contact between the highest point of the inclined surface of the limiting plate 8 and the limiting shaft 9 triggers a control signal to drive the bidirectional cylinder 10 to rotate the first rotating plate 6 and the second rotating plate 11 in the opposite direction, causing the push rod 13 and the push plate 14 to fall back to the initial unlifted state. At the same time, the unfolding component 1556 drives the support bar 155610 to return from the V-shaped flip state to a flat and horizontal state and stably store it inside the support component 1555. Then, the synchronous conveyor belt 2 drives the entire pushing structure to move backward and reset again, ready for the next pushing cycle. During this cycle, the cooperation between the limiting plate 8 and the limiting shaft 9 continuously detects the pushing stroke to ensure the accuracy and reliability of each pushing action. In summary, through the sequential and orderly actions of the pusher structure's rearward repositioning, the unfolding component 1556's pre-adaptive adjustment of the V-shaped groove posture according to the diameter of the material bucket before the pusher plate is lifted, or maintaining flat storage, the pusher plate 14 driven by the bidirectional cylinder 10 being lifted, and the synchronous conveyor belt 2 driving the overall forward push, combined with the position adjustment function of the adjustable support device 15, stable, accurate, and efficient pushing and conveying of the longitudinally inverted cylindrical material bucket is achieved, effectively solving the problems of poor adaptability and unstable pushing of existing pusher components.

Through the sequential actions of the pushing structure's backward repositioning, the unfolding component 1556's pre-adaptive adjustment of the V-shaped groove posture according to the material bucket diameter before the push plate 14 is raised (or maintaining flat storage), the lifting of the push plate 14 driven by the bidirectional cylinder 10, and the synchronous conveyor belt 2 driving the entire assembly forward, combined with the position adjustment function of the adjustable support device 15, stable, precise, and efficient pushing and conveying of longitudinally inverted cylindrical material buckets is achieved.
