Description

Technical Field

[0001] This utility model relates to the field of material conveying technology, and in particular to a dustproof and sealing structure for a chute. Background Technology

[0002] A chute is a common material conveying channel, mainly used to guide bulk materials to flow along the direction of gravity. However, due to the high-speed movement of materials and the open design of the chute structure, it often generates a large amount of dust, polluting the working environment.

[0003] Existing dustproof sealing solutions for conveyors mainly rely on fixed covers or flexible curtains. However, some dust covers are currently fixed by welding or bolts, which makes maintenance and replacement difficult and affects the maintenance efficiency of the conveying system.

[0004] Therefore, we propose a dustproof sealing structure for the chute to solve the existing problems. Utility Model Content

[0005] The purpose of this invention is to address the problems existing in the background technology by proposing a dustproof and sealing structure for a chute.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a dustproof and sealing structure for a chute, comprising an arc-shaped frame, a positioning plate, a locking plate, and a chute body. The arc-shaped frame is provided with an arc-shaped cover, and the positioning plate and locking plate are symmetrically provided at both ends of the arc-shaped frame. The groove wall of the chute body is inserted between the positioning plate and the locking plate. The positioning plate is provided with a friction component, and the locking plate is provided with a locking component. The locking component and the friction component cooperate with each other to lock the arc-shaped frame onto the chute body.

[0007] Preferably, the locking assembly consists of a crank arm, an operating plate, a protrusion, a rotating shaft, a magnetic block, and an iron base. The rotating shaft is rotatably mounted on the locking plate, the protrusion is mounted on the outer wall of the rotating shaft, the crank arm is symmetrically mounted on the shaft end of the rotating shaft, and the operating plate is mounted on the crank arm.

[0008] Preferably, the magnetic block is embedded in the locking plate, the iron base is disposed on the operating plate, and the iron base is magnetically positioned on the magnetic block.

[0009] Preferably, the friction assembly consists of a friction plate, a slider, a groove, and a spring, wherein the groove is formed within the positioning plate, and the slider is slidably disposed within the groove.

[0010] Preferably, one end of the spring abuts against the inner wall of the groove, the other end of the spring abuts against the slider, the original length of the spring is greater than the depth of the groove, and the friction plate is disposed at the other end of the slider.

[0011] Preferably, adhesive strips are symmetrically glued to both ends of the arc-shaped frame.

[0012] Preferably, the arc-shaped cover has base blocks at both ends, and the base blocks are mounted on the arc-shaped frame by bolts. Sealing strips are provided at the contact points between the arc-shaped cover and the arc-shaped frame, as well as at the contact points between the arc-shaped frame and the upper surface of the chute body.

[0013] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0014] In use, the dustproof sealing structure for the chute can be installed on an arc-shaped frame, which is then inserted into the chute body. At this time, the operator operates the locking component, causing the inner wall of the chute body and the positioning plate to press against each other. Under the action of the friction component, the friction between the chute body and the arc-shaped frame is greatly increased, thereby locking and positioning the arc-shaped frame on the chute body. Multiple arc-shaped frames with arc-shaped covers are sequentially positioned side by side on the chute body, and the arc-shaped frames are pressed and contacted by rubber strips. In this way, multiple arc-shaped frames with arc-shaped covers form a complete dustproof sealing structure for the chute, which protects the opening of the chute body from dust.

[0015] When the locking assembly is not in use, the operating plate is in a horizontal position, and the protrusion is hidden vertically downward inside the locking plate. When the friction assembly is not in use, the friction plate protrudes from the positioning plate.

[0016] When in use, the operator pulls the control panel downward to rotate the shaft, causing the protrusion to rotate to a horizontal position and press against the outer wall of the slide body. Under the pressure, the friction component works. At this time, the positioning plate approaches the slide body, the friction plate retracts under force, and the slider slides in the groove to compress the spring. Under the elastic force of the spring, the friction plate presses against the inner wall of the slide body. Through the cooperation of the above structure, the device is locked on the slide under the action of strong friction.

[0017] Furthermore, when the locking assembly is working, the operating plate is vertically downward, and the iron base is magnetically attracted by the magnet to position the operating plate, which can prevent the rotating shaft from spinning without strong external force.

[0018] This invention achieves an overall dustproof effect through the cooperation of multiple sealing structures. At the same time, the design of the locking component and friction component makes the device easy to install and convenient to disassemble and maintain. Attached Figure Description

Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0027] Example 1

[0028] like Figures 1-5 As shown, the present invention proposes a dustproof and sealing structure for a chute, comprising an arc-shaped frame 1, a positioning plate 4, a locking plate 5, and a chute body 7. The arc-shaped frame 1 is provided with an arc-shaped cover 3. Positioning plates 4 and locking plates 5 are symmetrically arranged at both ends of the arc-shaped frame 1. The groove wall of the chute body 7 is inserted between the positioning plates 4 and the locking plates 5. A friction assembly is provided on the positioning plate 4, and a locking assembly 6 is provided on the locking plate 5. The locking assembly 6 and the friction assembly cooperate to lock the arc-shaped frame 1 onto the chute body 7. During use, the arc-shaped cover 3 can be installed on the arc-shaped frame 1, and then the arc-shaped frame 1 can be inserted into the chute body. At point 7, the operator operates the locking assembly 6, causing the inner wall of the chute body 7 to press against the positioning plate 4. Under the action of the friction assembly, the friction between the chute body 7 and the arc frame 1 is greatly increased, thereby locking and positioning the arc frame 1 on the chute body 7. Multiple arc frames 1 with arc covers 3 are sequentially positioned side by side on the chute body 7. The two ends of the arc frame 1 are symmetrically glued with adhesive strips 8, and the arc frames 1 are pressed and contacted by the adhesive strips 8. In this way, multiple arc frames 1 with arc covers 3 constitute a complete dustproof and sealing structure for the chute, which protects the opening of the chute body 7 from dust.

[0029] The arc-shaped cover 3 has base blocks 2 at both ends. The base blocks 2 are bolted to the arc-shaped frame 1. Sealing strips are provided at the contact points between the arc-shaped cover 3 and the arc-shaped frame 1, as well as at the contact points between the arc-shaped frame 1 and the upper surface of the chute body 7, to ensure the sealing effect at the contact points of the structure.

[0030] Example 2

[0031] like Figures 1-5 As shown, the dustproof sealing structure for a chute proposed in this utility model, compared with Embodiment 1, further includes: a locking assembly 6 consisting of a crank arm 601, an operating plate 602, a protrusion 603, a rotating shaft 604, a magnetic block 605, and an iron base 606. The rotating shaft 604 is rotatably mounted on the locking plate 5, the protrusion 603 is located on the outer wall of the rotating shaft 604, the crank arm 601 is symmetrically arranged on the shaft end of the rotating shaft 604, and the operating plate 602 is located on the crank arm 601. In use, the operator pulls the operating plate 602 downward to drive the rotating shaft 604 to rotate, so that the protrusion 603 rotates to a horizontal state and abuts against the outer wall of the chute body 7.

[0032] The magnetic block 605 is embedded in the locking plate 5, and the iron base 606 is set on the operating plate 602. The iron base 606 is magnetically positioned on the magnetic block 605. The operating plate 602 is vertically downward. The iron base 606 is magnetically attracted by the magnetic block 605, thereby positioning the operating plate 602 and preventing the rotating shaft 604 from spinning without strong external force.

[0033] The friction assembly consists of a friction plate 401, a slider 402, a groove 403, and a spring 404. The groove 403 is formed inside the positioning plate 4, and the slider 402 is slidably disposed within the groove 403. One end of the spring 404 abuts against the inner wall of the groove 403, and the other end of the spring 404 abuts against the slider 402. The original length of the spring 404 is greater than the depth of the groove 403. The friction plate 401 is disposed at the other end of the slider 402. Under the action of the pressure, the friction assembly works. At this time, the positioning plate 4 approaches the slide body 7, and the friction plate 401 retracts under the force. Then, the slider 402 slides within the groove 403, squeezing the spring 404. Under the elastic force of the spring 404, the friction plate 401 abuts against the inner wall of the slide body 7. Through the cooperation of the above structures, the device is locked on the slide under the action of strong friction.
