[0016] Compared with the prior art, the present application has the following advantages: 1. When the present invention is working, the drive mechanism drives the active rollers of the two conveying mechanisms to rotate synchronously in opposite directions, thereby driving the corresponding conveyor belts to synchronously reverse transmission, forming a double-layer synchronous reverse conveying structure. This structure does not require the configuration of two independent single-layer conveyors to achieve bidirectional material transmission as in the traditional solution, effectively reducing equipment investment costs, simplifying layout and saving planar space. At the same time, the synchronous drive of the two conveying mechanisms by the drive mechanism ensures the coordination of the double-layer conveyor belt operation, avoiding the problems of asynchronous transmission and low efficiency that are prone to occur in traditional multiple independent equipment, and meeting the process requirements of bidirectional parallel flow of materials. 2. This invention uses a reducer to convert the high-speed, low-torque power output of motor A into low-speed, high-torque power, which is then transmitted to the main gear. This not only matches the speed and torque requirements required for the main gear to drive the upper drive gear, the transition gear, and the lower drive gear, but also avoids excessive gear transmission and material conveying speed loss due to excessively high output speed of motor A. Furthermore, by increasing the torque, it ensures stable meshing and transmission of each gear, preventing jamming or stoppage caused by insufficient power. 3. The present invention designs the drive mechanism and the belt conveyor to be detachably connected. When the drive mechanism fails, only the connection between the drive mechanism and the conveyor needs to be separated to remove the entire drive mechanism for repair or replacement, avoiding the problems of complicated operation and excessive time consumption caused by overall disassembly. 4. This invention can be optionally equipped with or without reinforcement components. When reinforcement components consisting of a movable plate, a square block, nut B, a telescopic rod, and screw B are installed, it can effectively prevent the connecting slot and the connecting block from loosening during the operation of the drive mechanism. The square block is inserted into the square groove to restrict the radial rotation of the connecting block, preventing relative slippage caused by gear transmission torque. It can also improve the overall load-bearing capacity of the connection and meet the reliable operation requirements under heavy load or high vibration conditions. When the reinforcement components are not installed, there is no need to operate the above-mentioned reinforcement components. The basic fixation or reverse disassembly can be completed simply by fixing the drive mechanism and slider A with the nut A and engaging the motor B drive protrusion with the groove seat. This greatly reduces the operation steps and is suitable for scenarios where efficiency is paramount, such as emergency maintenance and temporary replacement of the drive mechanism.

[0020] The base 3 is connected to the support frame 103 of the lower conveying mechanism 1 through a plurality of support columns 5 at the bottom end, and the base 3 is made of cast iron material, which has high density and can support the belt conveyor stably. The driving mechanism 4 is used for driving the driving rollers 101 of the two conveying mechanisms 1 to rotate in opposite directions synchronously, so that the two conveying mechanisms 1 form a double-layer synchronous reverse conveying structure with opposite conveying directions.

[0021] The two conveying mechanisms 1 arranged vertically constitute the core conveying structure, each conveying mechanism 1 supports the driving roller 101 and the driven roller 102 through the support frame 103, and the conveying belt 104 sleeved on the outer periphery of the driving roller 101 and the driven roller 102 can rotate with the roller body to realize material conveying, the support frames 103 of the two conveying mechanisms 1 are connected through the connecting rod 2 to ensure the stability of the vertical structure, and the support frame 103 of the lower conveying mechanism 1 is connected to the base 3 through a plurality of support columns 5 to ensure that the whole device is placed stably; during work, the driving mechanism 4 drives the driving rollers 101 of the two conveying mechanisms 1 to rotate in opposite directions synchronously, thereby driving the corresponding conveying belts 104 to transmit reversely synchronously, forming a double-layer synchronous reverse conveying structure, which does not need to configure two independent single-layer conveyors as in the traditional scheme to realize bidirectional transmission of materials (such as conveying qualified fruits and vegetables and returning unqualified fruits and vegetables), effectively reducing equipment investment cost, simplifying layout and saving plane space, and ensuring the coordination of the double-layer conveying belts 104 through the synchronous driving of the driving mechanism 4 on the two conveying mechanisms 1, avoiding the problems of asynchronous transmission and low efficiency of traditional multiple independent equipment, and meeting the process requirement of bidirectional parallel circulation of materials.

[0022] The specific structure of the driving mechanism 4 is as follows: the driving mechanism 4 comprises a square shell 401 connected to the top end of the base 3, a main gear 402 installed inside the square shell 401, an upper driving gear 403 located above the main gear 402 and in meshing connection with the main gear 402, a transition gear 404 located below the main gear 402 and in meshing connection with the main gear 402, and a lower driving gear 405 located below the transition gear 404 and in meshing connection with the transition gear 404, the transition of the transition gear 404 makes the rotation directions of the upper driving gear 403 and the lower driving gear 405 opposite, the upper driving gear 403 and the lower driving gear 405 are respectively connected to the transmission shafts of the upper and lower driving rollers 101, the main gear 402 is driven by a driving device 406, the driving device 406 comprises a speed reducer 4061 installed on the surface of the square shell 401 and a motor A 4062, the power of the motor A 4062 is transmitted to the main gear 402 after being reduced by the speed reducer 4061, the main gear 402, the upper driving gear 403, the transition gear 404 and the lower driving gear 405 are all in rotational connection with the inner wall of the square shell 401 through rotating rods 407 and bearings 408, a plurality of bearings 408 are fixed on the square shell 401, a plurality of rotating rods 407 are in turn connected to the above-mentioned gears at one end and are embeddedly fixed in the inner ring of the bearings 408 at the other end.

[0023] The driving mechanism 4 takes the square shell 401 connected with the top end of the base 3 as the installation carrier, and the inner wall of the square shell 401 is matched with the bearing 408 through the rotating rod 407 (one end of the rotating rod 407 is connected with the corresponding gear, and the other end is embeddedly fixed in the inner ring of the bearing 408, and the bearing 408 is fixed on the square shell 401), so as to realize the stable rotating installation of the main gear 402, the upper driving gear 403, the transition gear 404 and the lower driving gear 405 (that is, when the above gears rotate, the rotating rod 407 will rotate, the rotating rod 407 drives the inner ring of the bearing 408 to rotate, and the inner ring rotates along the outer ring fixed on the inner wall of the square shell 401), and the upper driving gear 403 is located above the main gear 402 and is engaged with the main gear 402, the transition gear 404 is located below the main gear 402 and is engaged with the main gear 402, and the lower driving gear 405 is located below the transition gear 404 and is engaged with the transition gear 404; during work, the driving device 406 installed on the surface of the square shell 401 provides power, and the power output by the motor A 4062 is first transmitted to the main gear 402 after being decelerated by the speed reducer 4061, so as to drive the main gear 402 to rotate; the main gear 402 directly drives the upper driving gear 403 engaged with it to rotate on one side, and drives the lower driving gear 405 engaged with the transition gear 404 to rotate through power transmission and rotation change on the other side, and the upper driving gear 403 and the lower driving gear 405 form opposite rotation directions by the transition effect of the transition gear 404; finally, the upper driving gear 403 and the lower driving gear 405 connected with the upper and lower driving rollers 101 transmission shafts respectively synchronously transmit the reverse rotation power to the corresponding driving rollers 101, so as to realize the synchronous reverse rotation of the two driving rollers 101 of the conveying mechanism 1.

[0024] The above-mentioned high-speed, low-torque power output by the motor A 4062 is converted into low-speed, high-torque power by the speed reducer 4061 and transmitted to the main gear 402, which not only matches the speed and torque requirements of the main gear 402 driving the upper driving gear 403, the transition gear 404 and the lower driving gear 405 to rotate, but also avoids the problem that the gear transmission is too fast and the material conveying speed is out of control due to the too high output speed of the motor A 4062, and can also ensure the stable meshing transmission of the gears by increasing the torque to prevent the problem of jamming or stop caused by insufficient power.

[0025] Embodiment 2 As shown in Figures 1-11 In this embodiment, the driving mechanism 4 and the belt conveyor in embodiment 1 are designed to be detachably connected, when the driving mechanism 4 fails, only the connection part of the driving mechanism 4 and the conveyor needs to be separated, and then the driving mechanism 4 can be taken down as a whole for maintenance or replacement, so as to avoid the problems of complicated operation and too long time caused by overall disassembly.

[0027] When installing, first, the square shell 401 of the driving mechanism 4 is connected to the bottom block 9 through the bottom end vertical rod 8, is aligned with the upper open slot seat 10 connected to the sliding block A7 on the top end guide rail A6 of the base 3, and is inserted into the upper open slot seat 10, so that the screw rods A11 on both sides of the bottom end of the bottom block 9 pass through the through holes A1001 at the bottom end of the upper open slot seat 10, and nuts A12 are screwed to complete the preliminary fixation of the driving mechanism 4 and the sliding block A7; at this time, the connecting slot seat 22 is aligned with the connecting block 24 (if not aligned, the connecting slot seat 22 can be rotated), and then the sliding block A7 is pushed to slide along the guide rail A6, the connecting block 24 at the end of the transmission rod 23 connected to the upper layer driving gear 403 and the lower layer driving gear 405 of the driving mechanism 4 is inserted into the connecting slot seat 22 at the end of the transmission shaft of the driving roller 101 of the two conveying mechanisms 1 (at this time, the protrusion 20 is aligned with the recessed slot seat 21), and then the motor B14 is started to drive the rotation of the double-thread symmetric screw rod 15 (the threads on both sides of the double-thread symmetric screw rod 15 are opposite and symmetric at the middle part, so that the rod sleeves 16 on both sides of the outer side wall are synchronously moved to both sides or to the middle part by rotation in different directions), the rod sleeves 16 on both sides of the outer side wall are synchronously approached along the guide rail B17 through the sliding block B18, the protrusion 20 is inserted into the recessed slot seat 21 on both sides of the upper open slot seat 10 through the connecting plate 19, the position fixation of the sliding block A7 is completed, and the basic fixation of the connecting slot seat 22 and the connecting block 24 is completed at this time; if reinforcement is needed (the corresponding reinforcement components are installed thereon, and the reinforcement components are the sum of the moving plate 26, the square block 29, the nut B28, the telescopic rod 25, and the screw rod B27), the moving plate 26 on both sides of the connecting slot seat 22 can be pushed (the telescopic rod 25 is shortened), so that the moving plate 26 moves to the direction of the connecting slot seat 22, finally, the square block 29 on the moving plate 26 passes through the square through slot 2201 of the connecting slot seat 22 and is inserted into the square recess 2401 of the connecting block 24, the nut B28 is screwed on the outer side wall of the screw rod B27 to lock the moving plate 26, and the reinforcement is completed. When disassembling, the nut B28 is unscrewed and the moving plate 26 is pulled to move away from the connecting slot seat 22, so that the square block 29 is separated from the square recess 2401 and the square through slot 2201 (the telescopic rod 25 is elongated, and the back-and-forth linear movement of the moving plate 26 is maintained through the telescopic rod 25), and the reinforcement is released; the motor B14 is started to drive the reverse rotation of the double-thread symmetric screw rod 15, so that the rod sleeve 16 drives the protrusion 20 to separate from the recessed slot seat 21, and the fixation of the sliding block A7 is released; then the sliding block A7 is pushed to make the connecting block 24 separate from the connecting slot seat 22, finally, the nut A12 is unscrewed and the bottom block 9 is taken out of the upper open slot seat 10, and the disassembly of the driving mechanism 4 and the belt conveyor is completed.

The matching structure of the square block 29 inserted into the square groove 2401 can limit the radial rotation of the connection block 24 in the connection groove seat 22, prevent the relative slipping of the connection block 24 and the connection groove seat 22 caused by the torque generated by the gear transmission, and further improve the load bearing capacity of the overall connection, thereby improving the fatigue resistance of the connection structure, slowing down the wear speed of the components even under the action of periodic load for a long time (such as frequent start-stop conveying of different weight materials), prolonging the service life of the connection structure, reducing the cost of frequent maintenance and replacement of components caused by insufficient bearing, and enabling the equipment to still operate reliably under heavy load working conditions.

[0029] When reinforcing without installing reinforcing components, the square block 29 is not inserted into the square through groove 2201 and the square groove 2401, and the nut B28 is not locked, and only the basic fixation of the driving mechanism and the slider A7 is completed by fixing the nut A12 and driving the protrusion 20 to engage the groove seat 21 by the motor B14, or the reverse operation can be performed to disassemble, which greatly reduces the operation steps, is especially suitable for emergency maintenance, temporary replacement of the driving mechanism, and other scenes where efficiency is prioritized, and can be selected according to actual needs.

[0030] The application also provides a use method of the double-layer synchronous transmission belt conveyor.

Step three: start the motor B14 in the surface connecting shell 13 of the support column 5, drive the double-thread symmetric screw rod 15 to rotate, make the rod sleeve 16 slide along the rail B17 through the slider B18, and then drive the protrusion 20 to insert into the groove seat 21 on both sides of the upper opening groove seat 10 through the connecting plate 19, to complete the position fixation of the slider A7, and at this time, the basic connection of the driving mechanism 4 and the conveyor main body is in place. Step four: start the motor A4062 of the driving device 406 on the surface of the square shell 401 of the driving mechanism 4, the high-speed and low-torque power output by the motor A4062 is converted into low-speed and high-torque power by the speed reducer 4061, and then the low-speed and high-torque power is transmitted to the main gear 402 and drives the main gear 402 to rotate, the main gear 402 drives the upper driving gear 403 to rotate in one direction and drives the lower driving gear 405 to rotate in the opposite direction through the transition gear 404, the upper driving gear 403 and the lower driving gear 405 drive the driving rollers 101 of the upper and lower conveying mechanisms 1 to rotate in opposite directions through the transmission rods 23, the connecting blocks 24 and the connecting groove bases 22, and then drive the conveying belts 104 on the outer peripheries of the driving rollers 101 and the driven rollers 102 to rotate in opposite directions, so that the materials can be placed on the upper and lower conveying belts 104, and bidirectional parallel conveying is realized; Step five: when the driving mechanism 4 is disassembled, the motor B14 is started to drive the double-thread symmetric screw rod 15 to rotate in the opposite direction, so that the rod sleeve 16 drives the protrusion 20 to move away from the groove base 21, the position of the sliding block A7 is fixed, the sliding block A7 is pushed to slide along the guide rail A6, the connecting block 24 is separated from the connecting groove base 22, the power connection between the driving mechanism 4 and the driving roller 101 is disconnected, finally the nut A12 on the screw rod A11 is unscrewed, and the bottom block 9 is taken out from the upper opening groove base 10, so that the driving mechanism 4 can be taken out as a whole.

[0031] The double-layer synchronous transmission belt conveyor and the use method thereof have the following advantages: When working, the driving mechanism 4 drives the driving rollers 101 of the two conveying mechanisms 1 to rotate in opposite directions, and then drives the conveying belts 104 corresponding to the driving rollers 101 to rotate in opposite directions, so that a double-layer synchronous reverse conveying structure is formed, the double-layer synchronous reverse conveying structure does not need to configure two independent single-layer conveyors to realize bidirectional conveying of materials, effectively reduces the equipment investment cost, simplifies the layout and saves the plane space, and can ensure the coordination of the operation of the double-layer conveying belts 104 through the synchronous driving of the driving mechanism 4 on the two conveying mechanisms 1, avoids the problems of asynchronous transmission and low efficiency of the traditional multiple independent devices, and meets the process requirement of bidirectional parallel flow of materials. The high-speed and low-torque power output by the motor A4062 is converted into low-speed and high-torque power by the speed reducer 4061 and then transmitted to the main gear 402, which is suitable for the speed and torque requirements of the rotation of the main gear 402, the upper driving gear 403, the transition gear 404 and the lower driving gear 405, avoids the problem that the gear transmission is too fast and the material conveying speed is out of control due to the too high output speed of the motor A4062, and can ensure the stable meshing transmission of the gears through the improvement of the torque and prevent the gears from being stuck or stopped due to insufficient power. The detachable connection between the driving mechanism 4 and the belt conveyor is designed, when the driving mechanism 4 fails, only the connection part of the driving mechanism 4 and the conveyor needs to be separated, the driving mechanism 4 can be taken out as a whole for maintenance or replacement, avoiding the problem of complicated operation and long time caused by overall disassembly; The reinforcing components can be selected to be added or not to be added. When the reinforcing components composed of the moving plate 26, the square block 29, the nut B28, the telescopic rod 25 and the screw rod B27 are added, the loosening of the connecting groove seat 22 and the connecting block 24 during the operation of the driving mechanism 4 can be effectively avoided. The radial rotation of the connecting block 24 is limited by the square block 29 inserted into the square groove 2401, the relative slipping caused by the gear transmission torque is prevented, and the carrying capacity of the overall connection is improved, meeting the reliable operation requirement under heavy load or high vibration working condition. When the reinforcing components are not added, the above reinforcing components are not needed to be operated, and only the nut A12 is used to fix the driving mechanism and the slider A7, and the motor B14 is used to drive the block 20 to be clamped in the groove seat 21, so that the basic fixation or reverse disassembly can be completed, the operation steps are greatly reduced, and the scenes of efficiency priority such as emergency maintenance and temporary replacement of the driving mechanism are adapted.
