Description

Technical Field

[0001] This invention relates to the field of conveyor technology, and in particular to an adjustable tilt guide plate mechanism and a spill prevention device and method for a belt conveyor transfer point. Background Technology

[0002] Conveyors are used for industrial transportation of materials such as mineral powder, coal powder, and sand. Belt conveyors, with their economic, reliable, safe, and continuous transport characteristics for conveying bulk materials, have been widely adopted in various industries. However, due to limitations such as site conditions and the size of the conveyor itself, multiple transfers are often required during the material transport process. A belt conveyor transfer point refers to the connection point where material is transferred from one conveyor to another during the transport process. However, because materials are prone to spilling out of the conveyor at transfer points, guide plates are installed to guide the falling material, preventing spillage and waste.

[0003] While the design of the guide plate has a good guiding effect, most existing guide plates are installed at a fixed angle as described in the cited patent CN203877477U. However, during the transfer of bulk materials, due to factors such as the drop height, the size of the material, and the unevenness of the incoming material, the material on the downstream conveyor often falls off-center. The inherent structure of the commonly used guide trough cannot adjust for the receiving conditions, which ultimately causes the belt to run off-center and is difficult to correct. This can lead to problems such as spillage and dust, or even belt tearing, which increases the daily maintenance for production users and causes certain economic losses and environmental pollution. Summary of the Invention

[0004] The purpose of this invention is to solve the problems existing in the prior art, and to propose an adjustable tilt angle guide plate mechanism and a spill prevention device and method for the transfer point of a belt conveyor.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: An adjustable tilt guide plate mechanism includes a bracket fixed to an upstream belt conveyor by bolts, and further includes: A material leveling seat is connected to the bottom end of the bracket, and a material leveling component is provided on the material leveling seat; An S-shaped guide seat is located on top of the material leveling seat and is used to guide the material from the end of the upstream belt conveyor into the material leveling component of the material leveling seat. An adjustable material guide shell is slidably disposed at the bottom of the material distribution seat; A hydraulic cylinder is movably positioned between the adjustable guide shell and the support.

[0006] Preferably, a protective shell is provided on the outside of the material leveling seat, and a fan device is provided on the protective shell. The fan device includes: The fan housing is fixedly mounted on the protective shell; A drive shaft is disposed inside the fan housing and is used to drive the impeller inside the fan housing; A drive motor is connected to one end of the drive shaft; The air inlet of the blower is connected to a dust extraction hose, and the end of the dust extraction hose away from the blower is connected to an S-shaped guide seat. The material leveling seat is fixed with a support for the drive motor.

[0007] Preferably, the drive shaft is configured as a crankshaft, and a movable rod is sleeved on the outer side of the crank portion of the drive shaft. A connecting plate is movably connected to the end of the movable rod away from the crank portion, and the connecting plate is fixedly connected to the S-shaped guide seat.

[0008] Preferably, the uniform material assembly comprises: The material distribution trough is located on the material distribution seat and is circular in shape. A rotating tube is rotatably disposed within the material equalization trough; Multiple partitions are evenly arranged in a circular pattern on the rotating tube; A material loading area is formed between two adjacent partitions; The material leveling seat has an upper inlet and a lower outlet on the upper and lower sides of the material leveling trough, respectively. The material leveling assembly is provided in two sets and is arranged horizontally on both sides of the material leveling base.

[0009] Preferably, the bottom of the connecting plate passes through the protective shell and is connected to a rack plate; Each of the two sets of material leveling components has a movable gear on its rotating tube, and both movable gears are meshed with a rack plate.

[0010] Preferably, the movable gear is configured as a one-way gear; When the rack plate meshes with one of the movable gears and drives the rotating tube to rotate, the other movable gear meshing with the rack plate is in a one-way free-spinning state.

[0011] Preferably, each of the rotating tubes is further provided with a limiting mechanism at its end, the limiting mechanism comprising: A fixing plate, which is fixed inside the protective shell; An elastic telescopic insertion rod, which is fixed to a fixed plate; A connecting pipe is fixed to the end of the rotating pipe, and the connecting pipe is provided with limiting holes that are evenly distributed around the circumference. The elastic telescopic rod is inserted into the limiting hole, and both the ends of the elastic telescopic rod and the limiting hole are tapered.

[0012] Preferably, the inner wall of the protective shell is fixed with a fixed rod coaxially arranged with the rotating tube. The fixed rod has a protrusion fixed on the rod body inside the rotating tube. The rotating tube has several concave holes between two adjacent partitions. A top rod is slidably connected in the concave holes. A force-bearing block that moves against the protrusion is connected to one end of the top rod. An elastic element with both ends connected to the inner wall of the rotating tube and the force-bearing block is sleeved on the outside of the top rod.

[0013] A spill prevention device for a belt conveyor transfer point includes an adjustable tilt guide plate mechanism, and further includes: Sealing plates are installed on both sides of the bottom of the S-shaped guide seat; The sealing plate is slidably connected to the uniform material seat via a slide rail.

[0014] This invention also discloses a method for preventing spillage at the transfer point of a belt conveyor, which involves the application of a spillage prevention device at the transfer point of a belt conveyor and includes the following steps: S1: Secure the bracket to the end of the upstream belt conveyor with bolts to ensure a stable connection between the mechanism and the belt conveyor; S2: The material from the upstream belt conveyor falls into the S-shaped guide seat, and its curved path prolongs the descent time, achieving multiple decelerations and reducing the impact on the downstream belt conveyor. S3: Start the fan equipment and use the dust extraction hose to suck up the dust generated by the falling material in the S-shaped guide seat, reducing dust pollution; S4: When the drive motor starts, the drive shaft drives the movable rod to reciprocate through its crank. The movable rod drives the S-shaped guide seat to swing horizontally through the connecting plate to prevent material blockage. At the same time, it drives the rack plate to move horizontally back and forth. S5: When the rack plate moves, since the movable gear is a one-way gear: The rack plate meshes with the movable gear of one of the material leveling components, driving the rotating tube to rotate. The rotating tube overcomes the resistance of the elastic telescopic rod, allowing the material to fall from the lower outlet into the adjustable guide shell. When the rack plate meshes with the movable gear of another set of material leveling components, the movable gear rotates in one direction and does not drive the rotating tube. The rotating tube stops to receive material under the insertion and engagement of the elastic telescopic rod and the limiting hole. When the rack plate moves back, it drives another set of rotating tubes to rotate and unload the material, while the movable gear that was originally meshed with the rack plate idles. At the same time, the limiting mechanism locks the previously unloaded rotating tube to ensure that it is stationary and receiving material; S6: When the rotating tube rotates to unload material, the force block abuts against the protrusion of the fixed rod. The force block pushes the push rod out under force, forcibly pushing out the stuck material. After unloading, the elastic element resets the push rod. S7: By extending and retracting the hydraulic cylinder, the inclination angle of the adjustable guide shell is adjusted to control the landing point of the material on the downstream belt conveyor.

[0015] Compared with the prior art, the present invention provides an adjustable tilt angle guide plate mechanism and a spill prevention device and method for a belt conveyor transfer point, which has the following beneficial effects: 1. The adjustable tilt guide plate mechanism and the anti-spillage device and method at the transfer point of the belt conveyor extend the material path by setting an S-shaped guide seat, realize multiple deceleration, reduce the impact force on the downstream belt, and at the same time, the double uniform material components work alternately to ensure that the material is evenly distributed on the downstream belt by quantitatively loading the material and rotating to unload it, thus solving the problems of material impact, uneven distribution, dust and blockage at the transfer point, and significantly improving the reliability and environmental protection of the belt conveyor system; 2. The adjustable tilt guide plate mechanism and the anti-spillage device and method for the transfer point of the belt conveyor are as follows: the output shaft of the drive motor drives the drive shaft to rotate, and the drive shaft drives the movable rod to move through its crank structure. The movable rod drives the S-shaped guide seat to move horizontally and reciprocally through the connecting plate. The shaking of the S-shaped guide seat can prevent the material from accumulating in the S-shaped guide seat and allow the material in the S-shaped guide seat to fall smoothly into the equalization trough. 3. The adjustable tilt guide plate mechanism and the anti-spillage device and method at the transfer point of the belt conveyor, through the alternating unloading of two sets of equalizing components, when the rack plate reciprocates and meshes with the movable gears of the two sets of equalizing components, the material moves to the left: the rack plate drives the left rotating tube to rotate and unload, while the right movable gear idles (the right rotating tube is locked by the limiting mechanism and is stationary to receive material); the material moves to the right: the rack plate drives the right rotating tube to unload, while the left movable gear idles (the left rotating tube is locked to receive material). The two equalizing components work alternately, quantitatively loading and rotating to unload material, ensuring that the material is evenly distributed on the downstream belt, effectively avoiding local overload of the downstream belt due to uneven material inflow, which could cause belt deviation and dust. 4. The adjustable tilt guide plate mechanism and the anti-spillage device and method for the transfer point of the belt conveyor, by setting an elastic telescopic rod to be inserted into the limiting hole, locks the position of the rotating tube at this time, ensuring that the rotating tube is stationary when receiving material, so that the material fills the loading area between the partitions; only when the rack plate meshes with the movable gear and drives the rotating tube to rotate, the rotating tube abuts against the conical surface of the elastic telescopic rod through the inner wall of the limiting hole, overcomes the limiting effect of the elastic telescopic rod on the rotating tube, and allows the elastic telescopic rod to avoid the rotation of the rotating tube, so that the rotating tube can be accurately unlocked when unloading, and avoids uneven distribution caused by the impact of material rotation before the material is full; 5. The adjustable tilt guide plate mechanism and the anti-spillage device and method for the transfer point of the belt conveyor use a hydraulic cylinder to push the adjustable guide shell to slide along the bottom of the material leveling seat, thereby changing the outlet angle of the guide shell and controlling the material drop point. It can cope with different material characteristics, conveyor belt speed and transfer height differences, and has strong applicability. Attached Figure Description

[0018] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments.

[0019] In the description of this invention, it should be understood that the terms "upper", "lower", "front", "rear", "left", "right", "top", "bottom", "inner", "outer", etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are only for the convenience of describing this invention and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this invention.

[0020] like Figures 1 to 3 As shown, this embodiment proposes an adjustable tilt guide plate mechanism, belonging to the technical field of belt conveyors. It includes a support 1 fixed to an upstream belt conveyor by bolts, and further includes: a material leveling seat 2, an S-shaped guide seat 3, an adjustable guide shell 4, and a hydraulic cylinder 5. The material leveling seat 2 is connected to the bottom end of the support 1, and a material leveling component is provided on the material leveling seat 2. The material leveling component evenly distributes the introduced material to the downstream belt conveyor, avoiding material accumulation or uneven loading. The S-shaped guide seat 3 is located at the top of the material leveling seat 2 and is used to guide the material from the end of the upstream belt conveyor into the material leveling seat 2. Inside the material leveling assembly, an S-shaped guide seat 3 is installed to extend the material path within a limited space, enabling multiple decelerations and reducing the impact on the downstream belt, replacing the method of material directly sliding down the guide plate at an incline; the adjustable guide shell 4 is slidably set at the bottom of the material leveling seat 2; the hydraulic cylinder 5 is movably set between the adjustable guide shell 4 and the support 1, and the hydraulic cylinder 5 extends and retracts to drive the adjustable guide shell 4 to slide along the bottom of the material leveling seat 2, changing the guide angle to adapt to different material drop requirements, solving the problems of material impact and uneven distribution at the transfer point, and significantly improving the reliability and environmental friendliness of the belt conveyor system.

[0021] like Figure 2 , Figure 3 and Figure 6As shown, in a preferred embodiment, based on the above method, a protective shell 201 is further provided on the outside of the material leveling seat 2. A fan device 6 is provided on the protective shell 201. The air inlet end of the fan device 6 is connected to a dust extraction hose 601. The end of the dust extraction hose 601 away from the fan device 6 is connected to the S-shaped material guide seat 3. The fan device 6 is connected to the S-shaped material guide seat 3 through the dust extraction hose 601, forming a closed dust collection path. The closed suction reduces the operation and greatly reduces the concentration of dust in the environment, effectively solving the problem of dust dispersion caused by the impact of falling materials at the transfer point. The fan device 6 includes components fixed to the protective shell. The fan housing 602 on 201, the drive shaft 603 for driving the impeller inside the fan housing 602, and the drive motor 604 connected to one end of the drive shaft 603 are all included. A support 605 for supporting the drive motor 604 is fixed on the material distribution seat 2. The support 605 is rigidly connected to the material distribution seat 2 to ensure the stability of the motor operation. The drive motor 604 drives the impeller to rotate through the drive shaft 603, generating a negative pressure airflow to extract dust. The rotation of the impeller directs the dust-laden airflow to be discharged or filtered. The fan equipment 6 is based on an existing centrifugal fan, and the structure of the drive shaft 603 of the drive motor 604 is improved and optimized as follows: It should be noted that the drive shaft 603 is configured as a crankshaft, and a movable rod 7 is sleeved on the outer side of the crank portion 6031 of the drive shaft 603. A connecting plate 701 is movably connected to the end of the movable rod 7 away from the crank portion 6031, and the connecting plate 701 is fixedly connected to the S-shaped guide seat 3. The drive motor 604 drives the crankshaft to rotate, and the drive shaft 603 forms an eccentric rotation mechanism with the movable rod 7 through the crank portion 6031, converting the rotational motion into linear reciprocating motion. The movable rod 7 is hinged to the connecting plate 701 fixed to the S-shaped guide seat 3 to achieve power transmission. When rotated, the connecting plate 701 is periodically displaced, driving the S-shaped guide seat 3 to move back and forth left and right, which can make the material inside shake, avoid the material blockage inside, and ensure that the material in the S-shaped guide seat 3 falls smoothly into the uniform material seat 2. It should be noted that since the upper end of the S-shaped guide seat 3 is at the end of the upstream belt conveyor, the opening of the S-shaped guide seat 3 should be set to a large opening so that it can move smoothly across the end of the upstream belt conveyor and catch the falling material. In addition, an anti-stick coating is added to the bottom of the S-shaped guide seat 3 to prevent sticky materials (such as wet coal) from adhering and blocking.

[0022] like Figure 2 , Figure 6 , Figure 7 , Figure 8 , Figure 9 , Figure 10 , Figure 11 and Figure 12As shown, in a preferred embodiment, based on the above method, the material leveling assembly further includes a circular material leveling trough 8 opened on the material leveling base 2, a rotating tube 801 rotatably connected in the material leveling trough 8, and partitions 802 evenly arranged on the rotating tube 801 in a circular pattern. A material loading area is formed between two adjacent partitions 802. The material leveling base 2 has an upper inlet 803 and a lower outlet 804 opened on the upper and lower sides of the material leveling trough 8, and two sets of material leveling assemblies are arranged horizontally on both sides of the material leveling base 2. The material enters the material leveling trough 8 from the upper inlet 803, and the rotating tube 801 drives the partitions 802 to rotate, so as to evenly distribute the material to each loading area. The material is discharged through the lower outlet 804. It should be noted that the bottom of the connecting plate 701 passes through the protective shell 201 and is connected to the rack plate 9; wherein, each of the rotating tubes 801 of the two sets of material leveling components is provided with a movable gear 10, and both movable gears 10 are meshed with the rack plate 9; furthermore, the movable gear 10 is set as a one-way gear, which is existing technology and will not be described in detail here. When the rack plate 9 meshes with one of the movable gears 10 and drives the rotating tube 801 to rotate, the other movable gear 10 meshing with the rack plate 9 is in a one-way free rotation state and will not drive the rotating tube 801 to rotate for unloading work; Specifically, the rack plate 9 is linked to the crank mechanism via the connecting plate 701. When the rack plate 9 moves, it drives two sets of movable gears 10 to rotate. The movable gears 10 adopt a one-way gear design to ensure that when one side of the movable gear 10 is driven, the other side of the movable gear 10 idles. The rotating tubes 801 of the two sets of feeding components achieve intermittent rotation through the gear and rack. Figure 7 Taking the front view as an example, when the rack plate 9 reciprocates and meshes with the movable gears 10 of the two sets of material leveling components, the rack plate 9 moves to the left: the meshing of the rack plate 9 and the movable gear 10 causes the left movable gear 10 to drive the left rotating tube 801 to rotate and unload the material, while the right movable gear 10 idles and cannot drive the rotating tube 801 to rotate, and the right rotating tube 801 remains stationary to receive the material; the rack plate 9 moves to the right: the rack plate 9 meshes with the right movable gear 10 and drives the right rotating tube 801 to unload the material, while the left movable gear 10 idles and cannot drive the rotating tube 801 connected to it to rotate, and the left rotating tube 801 remains stationary to receive the material. The two material leveling components work alternately, quantitatively loading the material and rotating to unload it, ensuring that the material is evenly distributed on the downstream belt, effectively avoiding local overload of the downstream belt due to uneven material intake, which could cause belt deviation and dust.

[0023] like Figure 2 , Figure 6 , Figure 7 , Figure 8 , Figure 9 , Figure 10 and Figure 11As shown, in a preferred embodiment, based on the above method, to further ensure that the rotating tube 801 connected to the movable gear 10 does not easily rotate in the idling state, each rotating tube 801 is also provided with a limiting mechanism. The limiting mechanism includes: a fixed plate 11, which is fixed inside the protective shell 201; an elastic telescopic rod 111, which is fixed on the fixed plate 11; and a connecting tube 12, which is fixed at the end of the rotating tube 801. The connecting tube 12 is provided with limiting holes 121 that are evenly distributed in a circle. The elastic telescopic rod 111 is inserted into the limiting hole 121. The ends of the elastic telescopic rod 111 and the limiting hole 121 are both set to be tapered. The tapered setting is beneficial to the quick insertion of the end of the elastic telescopic rod 111 into the limiting hole 121. On the other hand, when the movable gear 10 drives the rotating tube 801 to rotate, the tapered shape facilitates the elastic telescopic rod 111 to be inserted into the limiting hole 121. The retraction of rod 111 allows the elastic telescopic insert rod 111 to avoid the rotation of the rotating tube 801. When the movable gear 10 no longer drives the rotating tube 801 to rotate, the elastic telescopic insert rod 111 quickly resets under the action of the internal spring and inserts into the limiting hole 121. In actual use, in order to prevent the rotating tube 801 connected to the idling movable gear 10 from being unrestricted, causing the partition 802 on the rotating tube 801 to shake randomly due to the impact of the material falling from the upper inlet 803, thus affecting the loading capacity of the material between two adjacent partitions 802 of the rotating tube 801, a limiting mechanism is set to allow the rotating tube 801 to have sufficient time to fill the material loading area between two adjacent partitions 802 during the restriction period. This prevents the material loading area from being unfilled and then rotating to the lower outlet 804 under the subsequent meshing drive of the rack plate 9 and the movable gear 10, resulting in uneven distribution of the material falling onto the belt of the downstream belt conveyor. When the rack plate 9 meshes with the movable gear 10 and drives the connected rotating tube 801 to rotate, the meshing of the rack plate 9 with another movable gear 10 will not drive the connected rotating tube 801 to rotate. When the rotating tube 801 rotates, it will cooperate with the partition 802 to move the material contained between two adjacent partitions 802. As the rotating tube 801 rotates, the material between the two partitions 802 falls from the lower outlet 804 into the adjustable guide shell 4. As the rack plate 9 moves back, the movable gear 10 on the other rotating tube 801 meshes with the rack plate 9. During engagement, the rotating tube 801 is driven to rotate. When the rotating tube 801 rotates, the material in its equalization component is driven to rotate to the lower outlet 804 that matches it and falls down through the partition 802. When the rotating tube 801 rotates, the limiting hole 121 presses the end face of the elastic telescopic rod 111, so that the elastic telescopic rod 111 avoids the rotating tube 801 driven by the movable gear 10. This enables the two equalization components to work alternately and intermittently. During the intermittent stop, the material can be fully received, avoiding uneven distribution caused by the material being impacted and rotated before the material is full.

[0024] like Figure 2 , Figure 3 and Figure 4 As shown, in a preferred embodiment, based on the above method, a further step is to fix a fixed rod 13 coaxially arranged with the rotating tube 801 on the inner wall of the protective shell 201. A protrusion 131 is fixed on the rod body inside the rotating tube 801 of the fixed rod 13. Several recesses 8011 are opened between two adjacent partitions 802 in the rotating tube 801. A push rod 14 is slidably connected inside the recesses 8011. A force-bearing block 141 that moves against the protrusion 131 is connected to one end of the push rod 14 in the rotating tube 801. A sleeve with two ends respectively connected to the inner walls of the rotating tube 801 is fitted on the outside of the push rod 14. The elastic element 142 is connected to the wall and the force-bearing block 141; the fixed rod 13 is coaxially arranged with the rotating tube 801 and is fixed to the inner wall of the protective shell 201 to achieve radial positioning. When the rotating tube 801 rotates, the protrusion 131 periodically squeezes the force-bearing block 141, the push rod 14 is pressed out of the concave hole 8011, the push rod 14 forcibly pushes out the stuck object, the elastic element 142 stores energy, after the protrusion 131 is disengaged, the elastic element 142 resets and drives the push rod 14 to retract, so as to avoid the material between two adjacent partitions 802 being stuck and unable to be discharged smoothly, and improve the uniformity of material discharge.

[0025] like Figures 1 to 3 As shown, this embodiment proposes a spill prevention device for a belt conveyor transfer point, including the aforementioned adjustable tilt guide plate mechanism, and further including: a sealing plate 15, which is disposed on both sides of the bottom of the S-shaped guide seat 3 to prevent material from spilling out without entering the upper inlet 803 of the uniform material seat 2 when the S-shaped guide seat 3 moves back and forth; wherein, the sealing plate 15 is slidably connected to the uniform material seat 2 through a slide rail to improve the smoothness of sliding between the sealing plate 15 and the uniform material seat 2.

[0026] This invention also discloses a method for preventing spillage at the transfer point of a belt conveyor, which involves the application of a spillage prevention device at the transfer point of a belt conveyor and includes the following steps: S1: Fix bracket 1 to the end of the upstream belt conveyor with bolts to ensure a stable connection between the mechanism and the belt conveyor; S2: The material from the upstream belt conveyor falls into the S-shaped guide seat 3, and its curved path prolongs the descent time, achieving multiple decelerations and reducing the impact on the downstream belt conveyor. S3: Start the fan equipment 6 and use the dust extraction hose 601 to suck up the dust generated by the falling material in the S-shaped guide seat 3, thereby reducing dust pollution; S4: When the drive motor 604 starts, the drive shaft 603 drives the movable rod 7 to reciprocate through its crank. The movable rod 7 drives the S-shaped guide seat 3 to swing horizontally through the connecting plate 701 to prevent material blockage. At the same time, it drives the rack plate 9 to move horizontally back and forth. S5: When the rack plate 9 moves, since the movable gear 10 is a one-way gear: The rack plate 9 meshes with the movable gear 10 of one of the material equalization components, driving the rotating tube 801 to rotate. The rotating tube 801 overcomes the resistance of the elastic telescopic insertion rod 111, allowing the material to fall from the lower outlet 804 into the adjustable guide shell 4. When the rack plate 9 meshes with the movable gear 10 of another set of material leveling components, the movable gear 10 rotates in one direction and does not drive the rotating tube 801. The rotating tube 801 stops to receive material under the insertion and engagement of the elastic telescopic rod 111 and the limiting hole 121. When the rack plate 9 moves back, it drives another set of rotating tubes 801 to rotate and unload the material, and the movable gear 10 that was originally meshed with the rack plate 9 idles. At the same time, the limiting mechanism locks the previously unloaded rotating tube 801 to ensure that it is stationary and receiving material; S6: When the rotating tube 801 rotates to unload material, the force block 141 abuts against the protrusion 131 of the fixed rod 13. The force block 141 is pushed by the force to push the push rod 14 out, forcibly pushing out the stuck material. After unloading, the elastic element 142 resets the push rod 14. S7: By extending and retracting the hydraulic cylinder 5, the tilt angle of the adjustable guide shell 4 is adjusted to control the landing position of the material on the downstream belt conveyor.

10. A method for preventing spillage at a transfer point of a belt conveyor, comprising applying the anti-spillage device for a transfer point of a belt conveyor as described in claim 9, characterized in that... Includes the following steps: S1: Fix the bracket (1) to the end of the upstream belt conveyor with bolts to ensure a stable connection between the mechanism and the belt conveyor; S2: The material from the upstream belt conveyor falls into the S-shaped guide seat (3), and the descent time is extended through its curved path to achieve multiple decelerations and reduce the impact on the downstream belt conveyor. S3: Start the fan equipment (6) and use the dust extraction hose (601) to suck up the dust generated by the falling material in the S-shaped guide seat (3) to reduce dust pollution; S4: When the drive motor (604) starts, the drive shaft (603) drives the movable rod (7) to reciprocate through its crank. The movable rod (7) drives the S-shaped guide seat (3) to swing horizontally through the connecting plate (701) to prevent material blockage.
