Description

Technical Field

[0001] This invention relates to the field of conveying device technology, specifically to a biomass power generation raw material conveying system. Background Technology

[0002] Biomass pellet fuel, as a new type of energy, is widely used in existing technologies. In the production process of biomass pellet fuel, the pressurization step of the pellet mill is a crucial process, responsible for pressing the processed biomass raw materials into pellets for subsequent storage and transportation.

[0003] However, after biomass pellet fuel is produced, it often needs to be packaged in containers such as cloth bags or boxes. This often requires a lot of manpower for packaging, which is not suitable for large-scale processing and production. This not only leads to a slowdown in processing speed and a reduction in production efficiency, but also increases the production cost of biomass pellet fuel. Summary of the Invention

[0004] In view of the shortcomings of the prior art, the present invention provides a biomass power generation raw material conveying system and its usage method that enables workers to conveniently pack materials into boxes or bags in a quantitative manner.

[0005] This invention is achieved through the following technical solution: a biomass power generation feedstock conveying system is provided, including a conveyor chain, a gravity lifting platform on the conveyor chain, two push plates on the gravity lifting platform, a feeding cylinder located between the two push plates at the top of the conveyor chain, a through hole extending laterally along the left and right directions of the conveyor chain and flush with the left and right inner side walls of the feeding cylinder on the rear side wall, an insert plate adapted to the inner side wall of the through hole is provided in the through hole, a resetting device for retracting the front end of the insert plate into the through hole is provided on the rear side wall of the feeding cylinder, a material gate is provided on the lower end face of the feeding cylinder, a crossbar adapted to the push plates is provided on the rear side wall of the insert plate, and a driving device for opening and closing the material gate is provided on the crossbar. When the front end of the insert plate contacts the front side plate of the feeding cylinder, the driving device controls the material gate to open; when the front end of the insert plate retracts into the through hole, the driving device controls the material gate to close.

[0006] In use, this invention features a gravity lifting platform mounted on a conveyor chain. Two push plates are mounted on the gravity lifting platform, and a feeding cylinder is positioned above the conveyor chain between the two push plates. A through hole extending laterally along the left-right direction of the conveyor chain and aligned with the inner sidewalls of the feeding cylinder is formed on the rear sidewall of the feeding cylinder. An insert plate, adapted to the inner sidewall of the through hole, is placed within the through hole. A material gate is located at the lower end of the feeding port. A crossbar, adapted to the push plates, is mounted on the rear sidewall of the insert plate, and a driving device for opening and closing the material gate is mounted on the crossbar. When the front end of the insert plate is in contact with the front sidewall of the feeding cylinder, the driving device controls the material gate to open; when the front end of the insert plate retracts into the through hole, the driving device controls the material gate to close. During use, the conveyor chain needs to be activated to move the gravity lifting platform, thereby causing the push plates on the gravity lifting platform to move and engage with the horizontal... The lever contacts and pushes the crossbar towards the output end of the conveyor chain, causing the insert plate to move in the through hole towards the output end of the conveyor chain and fit against the front side plate of the feeding cylinder. This separates the space inside the feeding cylinder vertically. During this process, the drive device on the crossbar controls the material gate to open, causing the material between the insert plate and the material gate to fall onto the gravity lifting platform. The gravity lifting platform then moves downward under the gravity of the material falling onto it, driving the push plate downward and disengaging it from the crossbar. The insert plate is no longer pushed forward by the crossbar, and the front end of the insert plate returns to the through hole under the drive of the reset device, no longer separating the space inside the feeding cylinder vertically. The drive device then controls the material gate to close, and the push plate loses its backward push. The gravity lifting platform moves to the output end of the conveyor chain under the drive of the gravity lifting platform. This allows workers to conveniently pack materials into boxes or bags in a quantitative manner.

[0007] Preferably, the gravity lifting platform includes a vertical plate mounted on a conveyor chain. A sliding plate is mounted on the side wall of the vertical plate facing the output end of the conveyor chain. A first spring is provided between the sliding plate and the conveyor chain. A groove is formed on the side wall of the vertical plate facing the output end of the conveyor chain. The lower end of the push plate extends into the groove and is fixedly connected to the sliding plate. The gravity lifting platform includes a vertical plate mounted on a conveyor chain. A sliding plate is mounted on the side wall of the vertical plate facing the output end of the conveyor chain. A first spring is provided between the sliding plate and the conveyor chain. A groove is formed on the side wall of the vertical plate facing the output end of the conveyor chain. The lower end of the push plate extends into the groove and is fixedly connected to the sliding plate. Using the groove, vertical plate, sliding plate, and first spring, not only can the material in the feeding cylinder easily fall onto the sliding plate, but the increased material volume on the sliding plate also compresses the first spring, causing the sliding plate to move downwards. This causes the push plate to move downwards within the groove, thereby disengaging the push plate from the horizontal plate.

[0008] Preferably, the material gate includes two horizontal plates positioned below the feeding cylinder. The two horizontal plates are distributed along the front-back extension direction of the conveyor chain, and the adjacent side walls of the two horizontal plates are attached to and cover the discharge port of the feeding cylinder. The upper surface of the horizontal plates is flush with the lower surface of the feeding cylinder. Two rotating shafts are also provided below the feeding cylinder, and the two horizontal plates are located between the two rotating shafts. The rotating shafts extend laterally in the left-right direction and have a connecting plate fixedly connected to the lower surface of the feeding cylinder at their ends. The horizontal plates and rotating shafts are aligned and fixedly connected along the front-back extension direction of the conveyor chain. The material gate includes two horizontal plates positioned below the feeding cylinder. The two horizontal plates are distributed along the front-to-back extension direction of the conveyor chain, with their adjacent side walls abutting and covering the feeding cylinder outlet. The upper surface of the horizontal plates is flush with the lower surface of the feeding cylinder. Two rotating shafts are also positioned below the feeding cylinder, with the two horizontal plates located between them. The rotating shafts extend laterally in the left-right direction, and their ends are fixedly connected to connecting plates that are fixedly connected to the lower surface of the feeding cylinder. The horizontal plates and rotating shafts are aligned and fixedly connected along the front-to-back extension direction of the conveyor chain. As the insert plate moves towards the output end of the conveyor chain within the through hole and abuts against the front side plate of the feeding cylinder, the drive device controls the horizontal plates to rotate downwards around the rotating shafts, thereby opening the material gate. As the front end of the insert plate returns to the through hole under the drive of the reset device, the drive device controls the horizontal plates to return to their initial position around the rotating shafts, thereby closing the material gate.

[0009] Preferably, the driving device includes a steel wire rope that extends laterally along the front-rear direction of the conveyor chain and passes through two horizontal plates. The rear end of the steel wire rope is fixed to the crossbar, and the front end of the steel wire rope is fixed to the front side wall of the feeding cylinder. The drive unit includes a steel wire rope extending laterally along the conveyor chain and passing through two horizontal plates. The rear end of the steel wire rope is fixed to a crossbar, and the front end is fixed to the front side wall of the feeding cylinder. As the insert plate moves towards the output end of the conveyor chain within the through hole and comes into contact with the front side plate of the feeding cylinder, the distance from the rear end of the steel wire rope to the feeding cylinder shortens, and the steel wire rope is loosened and no longer fixes the horizontal plate. At this time, the horizontal plate loses the upward thrust of the steel wire rope and rotates downward around the axis under the action of gravity, thereby causing the drive unit to control the material gate to open. As the front end of the insert plate returns to the through hole under the drive of the reset device, the distance from the rear end of the steel wire rope to the feeding cylinder increases, and the steel wire rope is tightened. At this time, the horizontal plate, due to the upward thrust of the steel wire rope, rotates upward around the axis to return to the initial position, thereby causing the drive unit to control the material gate to close.

[0010] Preferably, two wire ropes are provided on the crossbar, and the two wire ropes are located on the left and right sides of the feed cylinder outlet. By providing two wire ropes on the crossbar and positioning them on the left and right sides of the feed cylinder outlet, the stability of the device during use is improved.

[0011] Preferably, a weighing sensor is provided on the upper surface of the slide plate, and an electromagnet fixedly connected to the conveyor chain is provided between the slide plate and the conveyor chain. The weighing sensor is electrically connected to the electromagnet. By providing a weighing sensor on the upper surface of the slide plate and an electromagnet fixedly connected to the conveyor chain between the slide plate and the conveyor chain, and electrically connecting the weighing sensor and the electromagnet, the material on the slide plate can be weighed. When the material on the slide plate reaches a certain weight, an electrical signal is sent to the electromagnet, activating the electromagnet to attract and fix the slide plate, causing the push plate to move downward in the slide groove, causing the push plate to disengage from the crossbar. This allows for precise control of the weight of the material fed from the feeding cylinder onto the slide plate.

[0012] Preferably, a counting sensor adapted to the vertical plate is provided on one side of the output end of the conveyor chain, and the counting sensor is electrically connected to the conveyor chain. By providing a counting sensor adapted to the vertical plate on one side of the output end of the conveyor chain and electrically connecting the counting sensor to the conveyor chain, the number of times the material is conveyed can be controlled. When the number of material conveying times reaches a preset number, the counting sensor can send an electrical signal to the conveyor chain to control the conveyor chain to stop moving, thereby facilitating the workers to bag or box the materials.

[0013] Preferably, the gravity lifting platform further includes a support plate disposed on the side of the slide away from the vertical plate and in contact with the slide. The support plate prevents material conveyed to the slide by the feeding cylinder from spilling out, thereby improving the stability of the device during use.

[0014] Preferably, the reset device includes a fixing plate fixedly connected to the upper surface of the insert plate. A second spring, extending laterally towards the feeding cylinder and fixedly connected to the rear side wall of the feeding cylinder, is provided on the side wall of the fixing plate facing the conveyor chain. The fixing plate and the second spring not only allow the front end of the insert plate to return to the through hole after losing forward thrust, but also compress the second spring during the process of the insert plate moving towards the output end of the conveyor chain and fitting against the front side plate of the feeding cylinder, thus avoiding interference with the normal operation of the device.

[0015] A method of using a biomass power generation feedstock transportation system includes the following steps:

[0016] a. First, preset the weighing sensor and the counting sensor, then start the conveyor chain to make the conveyor chain drive the gravity lifting platform to move.

[0017] b. During the movement, the push plate on the gravity lifting platform contacts the crossbar, pushing the insert plate to move in the through hole and compressing the second spring, so that the front end of the insert plate contacts the front side plate of the feeding cylinder, separating the space inside the feeding cylinder vertically. This shortens the distance between the wire rope on the crossbar and the feeding cylinder, so that the wire rope no longer fixes the crossbar. At this time, the crossbar loses the upward thrust of the wire rope and will rotate downward around the axis under the action of gravity, thereby opening the material gate and letting the material between the material gate and the insert plate fall onto the sliding plate between the support plate and the vertical plate.

[0018] c. When the weight of the material on the slide reaches the preset value of the weighing sensor, the weighing sensor sends an electrical signal to the electromagnet, which then activates the electromagnet to attract and fix the slide. This causes the slide to compress the first spring and move downwards within the slide groove, thus separating the push plate from the cross plate and ceasing contact with the crossbar. The gravity lifting platform loses its backward thrust and continues to move towards the output end of the conveyor chain under the drive of the conveyor chain. The material on the slide between the support plate and the vertical plate is then poured off from the output end of the conveyor chain for boxing or bagging. During this process, the push plate is counted by the counting sensor. When the counting sensor reaches the preset value, it sends an electrical signal to the conveyor chain, causing the conveyor chain to stop rotating. After the material is poured off the slide, the weight of the material on the slide is less than the preset value of the weighing sensor. The weighing sensor then sends an electrical signal to the electromagnet, ceasing to attract and fix the slide. The first spring loses its downward thrust and drives the slide and push plate to move away from the conveyor chain back to their initial position.

[0019] d. When the crossbar loses its forward thrust, the fixed plate no longer compresses the second spring, and the front end of the insert plate returns to the through hole under the push of the second spring. This stops the vertical separation of the space inside the feeding cylinder, increases the distance between the rear end of the wire rope and the feeding cylinder, and tightens the wire rope. This causes the crossbar to move upward around the rotation axis back to its initial position, closes the material gate, and the material inside the feeding cylinder moves downward to refill the space between the insert plate and the material gate. The above operation is repeated.

[0020] The beneficial effects of this invention are as follows: A gravity lifting platform is provided on the conveyor chain, two push plates are provided on the gravity lifting platform, and a feeding cylinder is provided above the conveyor chain between the two push plates. A through hole is provided on the rear side wall of the feeding cylinder, extending laterally along the left and right directions of the conveyor chain and flush with the inner side walls of the feeding cylinder. An insert plate adapted to the inner side wall of the through hole is provided in the through hole, and a material gate is provided on the lower end face of the feeding port. A crossbar adapted to the push plate is provided on the rear side wall of the insert plate, and a driving device for opening and closing the material gate is provided on the crossbar. When the front end of the insert plate is in contact with the front side plate of the feeding cylinder, the driving device controls the material gate to open. When the front end of the insert plate retracts into the through hole, the driving device controls the material gate to close. When the device is in use, the conveyor chain needs to be started to move the gravity lifting platform, so that the push plates on the gravity lifting platform move and the crossbar moves with the push plates. The lever contacts and pushes the crossbar towards the output end of the conveyor chain, causing the insert plate to move in the through hole towards the output end of the conveyor chain and fit against the front side plate of the feeding cylinder. This separates the space inside the feeding cylinder vertically. During this process, the drive device on the crossbar controls the material gate to open, causing the material between the insert plate and the material gate to fall onto the gravity lifting platform. The gravity lifting platform then moves downward under the gravity of the material falling onto it, driving the push plate downward and disengaging it from the crossbar. The insert plate is no longer pushed forward by the crossbar, and the front end of the insert plate returns to the through hole under the drive of the reset device, no longer separating the space inside the feeding cylinder vertically. The drive device then controls the material gate to close, and the push plate loses its backward push. The gravity lifting platform moves to the output end of the conveyor chain under the drive of the gravity lifting platform. This allows workers to conveniently pack materials into boxes or bags in a quantitative manner. Attached Figure Description

Detailed Implementation

[0030] To clearly illustrate the technical features of this solution, the following detailed implementation method will be used to explain the solution.

[0031] like Figures 1-7 The biomass power generation feedstock conveying system of the present invention includes a conveyor chain 4, on which a gravity lifting platform is provided. Two push plates 6 are provided on the gravity lifting platform. A feeding cylinder 3 is located above the conveyor chain 4, between the two push plates 6. A through hole 13 is provided on the rear side wall of the feeding cylinder 3, extending laterally along the left-right direction of the conveyor chain 4 and flush with the left and right inner side walls of the feeding cylinder 3. An insert plate 19 adapted to the inner side wall of the through hole 13 is provided within the through hole 13. The rear side wall of the feeding cylinder 3 is provided with a reset device for the front end of the insert plate 19 to retract into the through hole 13. The lower end face of the feeding cylinder 3 is provided with a material gate. The rear side wall of the insert plate 19 is provided with a crossbar 11 adapted to the push plate 6. The crossbar 11 is provided with a drive device for opening and closing the material gate. When the front end of the insert plate 19 contacts the front side plate of the feeding cylinder 3, the drive device controls the material gate to open. When the front end of the insert plate 19 retracts into the through hole 13, the drive device controls the material gate to close.

[0032] The gravity lifting platform includes a vertical plate 1 mounted on a conveyor chain 4. A sliding plate 14 is mounted on the side wall of the vertical plate 1 facing the output end of the conveyor chain 4. A first spring 16 is mounted between the sliding plate 14 and the conveyor chain 4. A groove 17 is formed on the side wall of the vertical plate 1 facing the output end of the conveyor chain 4. The lower end of the push plate 6 extends into the groove 17 and is fixedly connected to the sliding plate 14. By utilizing the groove 17, the vertical plate 1, the sliding plate 14, and the first spring 16, not only can the material in the feeding cylinder 3 fall onto the sliding plate 14 easily, but the sliding plate 14 can also compress the first spring 16 due to the increase of material, causing the sliding plate 14 to move downward. This causes the push plate 6 to move downward within the groove 17, thereby causing the push plate 6 to detach from the horizontal plate 10. The material gate includes two horizontal plates 10 positioned below the feeding cylinder 3. The two horizontal plates 10 are distributed along the front-to-back extension direction of the conveyor chain 4, with their adjacent sidewalls abutting and covering the discharge port of the feeding cylinder 3. The upper surface of the horizontal plates 10 is flush with the lower surface of the feeding cylinder 3. Two rotating shafts 12 are also positioned below the feeding cylinder 3, with the two horizontal plates 10 located between them. The rotating shafts 12 extend laterally in the left-right direction and are fixedly connected at their ends to connecting plates 9 that are fixedly connected to the lower surface of the feeding cylinder 3. The horizontal plate 10 is aligned and fixedly connected with the rotating shaft 12 along the front and rear extension direction of the conveyor chain 4. As the insert plate 19 moves towards the output end of the conveyor chain 4 within the through hole 13 and fits against the front side plate of the feeding cylinder 3, the drive device controls the horizontal plate 10 to rotate downward around the rotating shaft 12, thereby opening the material gate. As the front end of the insert plate 19 returns to the through hole 13 under the drive of the reset device, the drive device controls the horizontal plate 10 to return to the initial position around the rotating shaft 12, thereby closing the material gate. The drive device includes a steel wire rope 8 that extends laterally along the conveyor chain 4 and passes through two horizontal plates 10. The rear end of the steel wire rope 8 is fixed to the crossbar 11, and the front end of the steel wire rope 8 is fixed to the front side wall of the feeding cylinder 3. As the insert plate 19 moves towards the output end of the conveyor chain 4 within the through hole 13 and comes into contact with the front side plate of the feeding cylinder 3, the distance from the rear end of the steel wire rope 8 to the feeding cylinder 3 will shorten, and the steel wire rope 8 will be loosened and will no longer fix the horizontal plate 10. At this time, the horizontal plate 10 will rotate downward around the rotating shaft 12 under the action of gravity because it loses the upward thrust of the steel wire rope 8, thereby enabling the drive device to control the material gate to open. As the front end of the insert plate 19 returns to the through hole 13 under the drive of the reset device, the distance from the rear end of the steel wire rope 8 to the feeding cylinder 3 will increase, and the steel wire rope 8 will be tightened. At this time, the horizontal plate 10 will rotate upward around the rotating shaft 12 to return to the initial position due to the upward thrust of the steel wire rope 8, thereby enabling the drive device to control the material gate to close. By setting two steel wire ropes 8 on the crossbar 11, and placing the two steel wire ropes 8 on the left and right sides of the discharge port of the feeding cylinder 3, the stability of the device during use is improved.By installing a weighing sensor 18 on the upper surface of the slide plate 14 and an electromagnet 15 fixedly connected to the conveyor chain 4 between the slide plate 14 and the conveyor chain 4, the weighing sensor 18 and the electromagnet 15 are electrically connected. The weighing sensor 18 and the electromagnet 15 can be used to weigh the material on the slide plate 14. When the material on the slide plate 14 reaches a certain weight, an electrical signal is sent to the electromagnet 15 to activate the electromagnet 15 to attract and fix the slide plate 14, which drives the push plate 6 to move downward in the slide groove 17, causing the push plate 6 to disengage from the crossbar 11. In this way, the weight of the material from the feeding cylinder 3 to the slide plate 14 can be precisely controlled. A counting sensor 20, adapted to the vertical plate 1, is installed on one side of the output end of the conveyor chain 4 and electrically connected to the conveyor chain 4. The counting sensor 20 can control the number of material conveying cycles. When the preset number of material conveying cycles is reached, the counting sensor 20 sends an electrical signal to the conveyor chain 4, controlling it to stop moving. This facilitates the bagging or boxing of materials by workers. The gravity lifting platform also includes a support plate 2 installed on the side of the slide plate 14 away from the vertical plate 1 and attached to the slide plate 14. The support plate 2 prevents material conveyed by the feeding cylinder 3 from spilling onto the slide plate 14, thereby improving the stability of the device during use. The reset device includes a fixed plate 5 fixedly connected to the upper end face of the insert plate 19. A second spring 7 is provided on the side wall of the fixed plate 5 facing the conveyor chain 4, extending laterally towards the feeding cylinder 3 and fixedly connected to the rear side wall of the feeding cylinder 3. Using the fixed plate 5 and the second spring 7, not only can the front end of the insert plate 19 return to the through hole 13 after losing forward thrust, but the second spring 7 can also be compressed during the movement of the insert plate 19 towards the output end of the conveyor chain 4 and its contact with the front side plate of the feeding cylinder 3, thus avoiding interference with the normal operation of the device. By positioning the wire rope 8 on the side of the rotating shaft 12 away from the feeding cylinder 3, the horizontal plate 10 can easily rotate around the rotating shaft 12. By setting the front end of the insert plate 19 to a tapered shape, the insert plate 19 can easily move within the through hole 13 towards the output end of the conveyor chain 4 and its contact with the front side plate of the feeding cylinder 3. By providing two reset devices on the insert plate 19, with the two reset devices laterally distributed along the left and right directions of the insert plate 19, the reset effect of the insert plate 19 during use can be improved.

[0033] A method of using a biomass power generation feedstock transportation system includes the following steps:

[0034] a. First, preset the weighing sensor 18 and the counting sensor 20, and then start the conveyor chain 4 to make the conveyor chain 4 drive the gravity lifting platform to move.

[0035] b. During the movement, the push plate 6 on the gravity lifting platform contacts the crossbar 11, pushes the insert plate 19 to move in the through hole 13, and compresses the second spring 7, so that the front end of the insert plate 19 contacts the front side plate of the feeding cylinder 3, and the space inside the feeding cylinder 3 is separated vertically, thereby shortening the distance between the wire rope 8 on the crossbar 11 and the feeding cylinder 3, so that the wire rope 8 no longer fixes the crossbar 10. At this time, the crossbar 10 loses the upward pushing force of the wire rope 8, and under the action of gravity, it will rotate downward around the rotating shaft 12, thereby opening the material gate and causing the material between the material gate and the insert plate 19 to fall onto the sliding plate 14 between the support plate 2 and the vertical plate 1.

[0036] c. When the weight of the material on the slide plate 14 reaches the preset value of the weighing sensor 18, the weighing sensor 18 sends an electrical signal to the electromagnet 15, activating the electromagnet 15 to attract and fix the slide plate 14. This causes the slide plate 14 to compress the first spring 16 and move downwards within the slide groove 17, thereby causing the push plate 6 to detach from the horizontal plate 10 and no longer contact the horizontal bar 11. The gravity lifting platform loses its backward thrust and, driven by the conveyor chain 4, continues to move towards the output end of the conveyor chain 4, dumping the material on the slide plate 14 between the support plate 2 and the vertical plate 1 from the output end of the conveyor chain 4. During the process of packing or bagging, the pusher plate 6 will be counted by the counting sensor 20. When the counting sensor 20 reaches the preset value, the counting sensor 20 will send an electrical signal to the conveyor chain 4 to stop the conveyor chain 4 from rotating. After the material is poured off the slide plate 14, the weight of the material on the slide plate 14 is less than the preset value of the weighing sensor 18. The weighing sensor 18 sends an electrical signal to the electromagnet 15 and no longer attracts and fixes the slide plate 14. The first spring 16 loses its downward thrust and drives the slide plate 14 and the pusher plate 6 to move away from the conveyor chain 4 and return to the initial position.

[0037] d. When the crossbar 11 loses its forward thrust, the fixed plate 5 no longer compresses the second spring 7, and the front end of the insert plate 19 returns to the through hole 13 under the push of the second spring 7, no longer separating the upper and lower spaces in the feeding cylinder 3, increasing the distance between the rear end of the wire rope 8 and the feeding cylinder 3, and tightening the wire rope 8, it drives the crossbar 10 to move upward around the rotating shaft 12 back to the initial position, closes the material gate, and the material in the feeding cylinder 3 moves downward to refill the space between the insert plate 19 and the material gate, and repeats the above operation.

[0038] Of course, the above description is not limited to the examples above. Technical features not described in this invention can be implemented by or using existing technology, and will not be repeated here.

A second spring (7) is provided on the side wall of the fixing plate (5) facing the conveyor chain (4), extending laterally toward the feeding cylinder (3) and fixed to the rear side wall of the feeding cylinder (3).

6. The method of using the biomass power generation feedstock conveying system according to claim 5, characterized in that, Includes the following steps: a. Set the preset values ​​for the symmetrical weighing sensor (18) and the counting sensor (20), and start the conveyor chain (4) so ​​that the conveyor chain (4) drives the gravity lifting platform to move. b. Make the push plate (6) on the gravity lifting platform contact the crossbar (11) during the movement, push the insert plate (19) to move in the through hole (13), and compress the second spring (7) so that the front end of the insert plate (19) contacts the front side plate of the feeding cylinder (3), so that the space inside the feeding cylinder (3) is separated vertically, thereby shortening the distance between the wire rope (8) on the crossbar (11) and the feeding cylinder (3), so that the wire rope (8) is no longer fixed to the cross plate (10). The cross plate (10) loses the upward pushing force of the wire rope (8) and will rotate downward around the pivot (12) under the action of gravity, thereby opening the material gate and causing the material between the material gate and the insert plate (19) to fall onto the slide plate (14) between the support plate (2) and the vertical plate (1). c. When the weight of the material on the slide plate (14) reaches the preset value of the weighing sensor (18), the weighing sensor (18) sends an electrical signal to the electromagnet (15), activating the electromagnet (15) to attract and fix the slide plate (14), causing the slide plate (14) to compress the first spring (16) and move downward in the slide groove (17), thereby causing the push plate (6) to separate from the crossbar (11) and no longer contact the crossbar (11). The gravity lifting platform loses its backward thrust and will continue to move towards the output end of the conveyor chain (4) under the drive of the conveyor chain (4), and dump the material on the slide plate (14) between the support plate (2) and the vertical plate (1) from the output end of the conveyor chain (4). As the material is loaded into boxes or bags, the pusher plate (6) will be counted by the counting sensor (20). When the counting sensor (20) reaches the preset value, the counting sensor (20) will send an electrical signal to the conveyor chain (4) to stop the conveyor chain (4) from rotating. After the material is poured off the slide plate (14), the weight of the material on the slide plate (14) is less than the preset value of the weighing sensor (18). The weighing sensor (18) sends an electrical signal to the electromagnet (15) and no longer holds the slide plate (14) in place. The first spring (16) loses its downward thrust and drives the slide plate (14) and the pusher plate (6) to move away from the conveyor chain (4) and return to their initial positions. d. The crossbar (11) loses its forward thrust, the fixed plate (5) no longer compresses the second spring (7), and the front end of the insert plate (19) returns to the through hole (13) under the push of the second spring (7), no longer separating the space inside the feeding cylinder (3), increasing the distance between the rear end of the wire rope (8) and the feeding cylinder (3), and tightening the wire rope (8), causing the crossbar (10) to move upward around the rotating shaft (12) back to the initial position, closing the material gate, and the material in the feeding cylinder (3) moves downward to refill the space between the insert plate (19) and the material gate, and repeats the above steps.
