Abstract
Description
Technical Field
[0001] This utility model relates to the field of belt conveyor technology, specifically to an anti-clogging chute device for a belt conveyor transfer point. Background Technology
[0002] In material conveying systems, the chute device at the transfer point of a belt conveyor is a key component for transferring materials from the upstream conveyor to the downstream conveyor.
[0003] However, existing chute devices lack anti-clogging functionality during actual use. This means that the chute device can only rely on its own performance for conveying materials. When the material is viscous, it cannot be guided in time, leading to blockage of the chute device. To address this, we propose an anti-clogging chute device for the transfer point of a belt conveyor. Utility Model Content
[0004] The purpose of this invention is to provide an anti-clogging chute device for the transfer point of a belt conveyor, so as to solve the problems mentioned in the background art.
[0005] To achieve the above objectives, this utility model provides the following technical solution: an anti-clogging chute device for a belt conveyor transfer point, comprising a base plate, electric telescopic rods fixedly installed on the left and right sides of the top of the base plate by bolts, a lifting plate fixedly connected to the top of the electric telescopic rods, chute plates fixedly connected to the top of the lifting plate by support rods around its perimeter, a motor fixedly installed on one side of the lifting plate by bolts, a rotating rod fixedly connected to the output end of the motor, a rotating cylinder fixedly connected to the surface of the rotating rod, a first vibrating rod fixedly connected to the left side of the rotating cylinder, and a second vibrating rod fixedly connected to the right side of the rotating cylinder.
[0006] Preferably, a fixing plate is fixedly connected to both sides of the chute plate, and a feed hopper is fixedly connected to the inner side of the fixing plate.
[0007] Preferably, a battery box is fixedly connected to the top of the base plate by bolts, and a storage battery is fixedly connected to the inner cavity of the battery box by bolts. A charging port is provided at the middle of one side of the battery box, and the output end of the charging port is unidirectionally electrically connected to the input end of the storage battery.
[0008] Preferably, the lifting plate has a through hole at its middle end, and the through hole has a rectangular structure.
[0009] Preferably, a base is fixedly connected to the right side of the top of the lifting plate, a damping shock absorber is fixedly connected to the top of the base, a telescopic spring is provided on the surface of the damping shock absorber, a movable plate is fixedly connected to the top of the damping shock absorber, a dredging rod is fixedly connected to the middle of the top of the movable plate, and the top of the dredging rod penetrates the inner cavity of the feed hopper and extends into the inner cavity of the feed hopper.
[0010] Preferably, a PLC controller is fixedly mounted on the top of the base plate by bolts, and the output terminal of the PLC controller is unidirectionally electrically connected to the input terminal of the motor and the electric telescopic rod.
[0011] Compared with the prior art, the beneficial effects of this utility model are as follows:
[0012] 1. This utility model uses an electric telescopic rod to drive the lifting plate to move up and down, thereby raising and lowering the chute plate and the feed hopper as a whole. The height can be adjusted according to the conveying volume to avoid material accumulation. The motor drives the rotating rod and rotating cylinder to rotate, causing the first and second vibrating rods to periodically strike the chute plate, generating vibration to prevent material adhesion. Combined with the real-time unblocking of the feed hopper by the unblocking rod, a dual anti-blocking mechanism of "vibration anti-sticking + mechanical unblocking" is formed.
[0013] 2. This utility model utilizes a buffer system composed of a damping shock absorber and a telescopic spring to absorb the impact force when materials fall, reducing equipment vibration and noise. When a large amount of material impacts the feed hopper, the movable plate compresses the damping shock absorber and the telescopic spring, providing a buffering effect. After the material decreases, the elastic components return to their original shape, ensuring that the unblocking rod always maintains an effective working position, improving equipment stability and service life. The fixed plates on both sides of the chute are fixedly connected to the feed hopper, forming a closed conveying channel and reducing dust emissions. The rectangular through-hole design of the lifting plate reduces equipment weight and facilitates observation and cleaning of internal material accumulation. All components are connected by bolts, making disassembly and replacement easy and reducing maintenance difficulty. Attached Figure Description

[0020] Example 1:
[0021] Please see Figures 1-3 The following technical solution is provided, specifically disclosing: a chute device for preventing blockage at the transfer point of a belt conveyor, including a base plate 1, electric telescopic rods 18 are fixedly installed on the left and right sides of the top of the base plate 1 by bolts, a lifting plate 2 is fixedly connected to the top of the electric telescopic rods 18, a chute plate 3 is fixedly connected to the top of the lifting plate 2 by support rods 7, a motor 14 is fixedly installed on one side of the lifting plate 2 by bolts, a rotating rod 12 is fixedly connected to the output end of the motor 14, a rotating cylinder 20 is fixedly connected to the surface of the rotating rod 12, a first vibrating rod 19 is fixedly connected to the left side of the rotating cylinder 20, and a second vibrating rod 21 is fixedly connected to the right side of the rotating cylinder 20;
[0022] In actual use, the lifting plate 2 is driven up and down by the electric telescopic rod 18, which in turn drives the chute plate 3 and the feed hopper 4 to rise and fall as a whole. The height can be adjusted according to the conveying volume to avoid material accumulation. The motor 14 drives the rotating rod 12 and the rotating cylinder 20 to rotate, so that the first vibrating rod 19 and the second vibrating rod 21 periodically strike the chute plate 3 to generate vibration, which prevents material from sticking. Combined with the real-time unblocking of the feed hopper 4 by the unblocking rod 6, a dual anti-blocking mechanism of "vibration anti-sticking + mechanical unblocking" is formed.
[0023] Example 2:
[0024] Please see Figure 1 and Figure 2 The following technical solution is provided, specifically: A fixing plate 5 is fixedly connected to both sides of the chute plate 3; a feed hopper 4 is fixedly connected to the inner side of the fixing plate 5; a battery box 17 is fixedly connected to the top of the bottom plate 1 by bolts; a storage battery 16 is fixedly connected to the inner cavity of the battery box 17 by bolts; a charging port 15 is provided at the middle of one side of the battery box 17; the output end of the charging port 15 is unidirectionally electrically connected to the input end of the storage battery 16; a through hole 11 is provided at the middle of the lifting plate 2; the through hole 11 has a rectangular structure; and a fixed... A base 8 is fixedly connected, and a damping shock absorber 9 is fixedly connected to the top of the base 8. A telescopic spring 22 is provided on the surface of the damping shock absorber 9. A movable plate 10 is fixedly connected to the top of the damping shock absorber 9. A dredging rod 6 is fixedly connected to the middle of the top of the movable plate 10. The top of the dredging rod 6 passes through the inner cavity of the feed hopper 4 and extends into the inner cavity of the feed hopper 4. A PLC controller 13 is fixedly installed on the top of the base plate 1 by bolts. The output end of the PLC controller 13 is unidirectionally electrically connected to the input end of the motor 14 and the electric telescopic rod 18.
[0025] In actual use, the buffer system composed of damping shock absorber 9 and telescopic spring 22 can absorb the impact force when materials fall, reducing equipment vibration and noise. When a large amount of material impacts the feed hopper 4, the movable plate 10 compresses the damping shock absorber 9 and telescopic spring 22, playing a buffering role; after the material decreases, the elastic component returns to its original shape, ensuring that the unblocking rod 6 always maintains an effective working position, improving equipment stability and service life. The fixed plates 5 on both sides of the chute plate 3 are fixedly connected to the feed hopper 4, forming a closed conveying channel and reducing dust emission. The rectangular through hole 11 design of the lifting plate 2 reduces the weight of the equipment and facilitates observation and cleaning of internal accumulated materials. All components are connected by bolts, making them easy to disassemble and replace, reducing maintenance difficulty.
[0026] In use: The PLC controller 13 starts the electric telescopic rod 18 according to the preset program to adjust the height of the lifting plate 2, so that the feed hopper 4 and the conveyor belt maintain the optimal distance. At the same time, the motor 14 drives the rotating rod 12 to rotate, which drives the first vibrating rod 19 and the second vibrating rod 21 on the rotating drum 20 to periodically strike the chute plate 3. The vibration breaks the friction between the materials and prevents them from clumping and blocking. At the same time, when the second vibrating rod 21 rotates, it will squeeze the movable plate 10 and force the movable plate 10 to compress the damping shock absorber 9 and the telescopic spring 22 downward. When the second vibrating rod 21 separates from the movable plate 10, the damping shock absorber 9 returns to its original position and drives the unblocking rod 6 to move up and down to realize material conveying. The unblocking rod 6 continuously stirs the material to prevent bridging or blockage. At the same time, the buffer system protects the equipment from impact damage. The charging port 15 is connected to an external power source to charge the battery 16. The battery supplies power to the motor 14 and the electric telescopic rod 18.
