Description

Technical Field

[0002] A belt conveyor, also known as a belt conveyor, is a machine that transports materials continuously. It mainly consists of a conveyor belt, a drive unit, rollers, idlers, a tensioning device, and a frame.

[0003] In the process of transporting raw materials, the belt conveyor needs to be driven by the drive roller of the belt conveyor to transport the raw materials. In order to save operating costs, how to drive the belt conveyor's drive roller to drive the brush roller of the cleaning device at the same time is a problem that needs to be considered by those skilled in the art.

[0004] An existing patent (publication number: CN220549647U) discloses a cleaning device for a belt conveyor and a belt conveyor. The cleaning device includes: a brush roller, which is rotatably mounted on the frame of the belt conveyor and abuts against the belt of the belt conveyor; and a chain, which drives the brush roller to rotate synchronously with the drive roller of the belt conveyor. This disclosed cleaning device connects the brush roller to the drive roller of the belt conveyor through the chain and drives the brush roller to rotate synchronously with the drive roller, thereby achieving the removal of residual material on the belt while saving operating costs.

[0005] To address the aforementioned issues, existing patents offer solutions. However, these solutions have certain limitations in practice. When conveying materials with large particle size, high drop, and high speed, existing buffer brackets cannot effectively absorb the impact force of the materials, resulting in the conveyor belt still being subjected to significant impact and affecting its service life.

[0006] To address this, a buffer bracket for belt conveyors is proposed. Utility Model Content

[0028] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. 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.

[0029] Please see Figure 1-5 The present invention provides the following technical solution:

[0030] A buffer bracket for a belt conveyor includes a conveyor belt 1, with frames 15 installed on both the front and rear sides of the conveyor belt 1, and buffer grooves 13 opened on opposite sides of the two frames 15. A buffer mechanism 4 and an auxiliary mechanism 2 are installed on the left side of the conveyor belt 1.

[0031] The buffer mechanism 4 includes a first buffer frame 401, an inflation tube 402, two arc plates 403, two limiting plates 404, and an air cushion 405. The surface of the first buffer frame 401 is in contact with the interior of the buffer groove 13. The front side of the inflation tube 402 passes through the arc plate 403 and is fixedly connected to the rear side of the air cushion 405. The top of the arc plate 403 is fixedly connected to the bottom of the first buffer frame 401. The top of the limiting plate 404 is fixedly connected to the bottom of the arc plate 403. The surface of the air cushion 405 is in contact with the bottom of the first buffer frame 401.

[0032] In this embodiment: by fixing the top of the limiting plate 404 to the bottom of the arc plate 403, the first buffer frame 401 can be easily moved and adjusted inside the buffer groove 13 by the arc plate 403, so that the limiting plate 404 limits the first buffer frame 401 by the arc plate 403. When the material impacts the first buffer frame 401, the first buffer frame 401 compresses the air in the air cushion 405 to form the pressure of the air cushion 405, thereby generating a buffering force, which facilitates the buffering of the material.

[0033] Specifically, such as Figure 2 As shown, the auxiliary mechanism 2 includes a connecting plate 201 disposed on the left side of the frame 15, and a material inclined block 202 is fixedly connected to the right side of the connecting plate 201.

[0034] Specifically, such as Figure 2 As shown, the bottom of the material inclined block 202 is provided with four hinges 203 and a support block 205. The material inclined block 202 and the support block 205 are connected by hinges 203.

[0035] Specifically, such as Figure 2 As shown, five limiting springs 204 are fixedly connected to the top of the support block 205, and the top of the limiting springs 204 is fixedly connected to the bottom of the material inclined block 202.

[0036] In this embodiment: by rotating the connection between the material inclined block 202 and the support block 205 through the hinge 203, the material inclined block 202 can easily transfer materials through the hinge 203, and the top of the limiting spring 204 can be fixedly connected to the bottom of the material inclined block 202, thereby facilitating the support block 205 to limit the material inclined block 202 through the limiting spring 204, achieving the effect of limiting the material inclined block 202.

[0037] Specifically, such as Figure 3As shown, a buffer plate 16 is fixedly connected to the right side of the material inclined block 202, and three rollers 5 are rotatably connected to the top of the buffer plate 16. The bottom of the buffer plate 16 is in contact with the top of the first buffer frame 401.

[0038] Specifically, such as Figure 3 , Figure 5 As shown, two limiting blocks 6 are fixedly connected to the front and rear sides of the top of the buffer plate 16, and two sliding grooves 14 are opened on the opposite side of the two frames 15, with the surface of the limiting block 6 in contact with the inside of the sliding groove 14.

[0039] In this embodiment: by making the bottom of the buffer plate 16 contact the top of the first buffer frame 401, the air cushion 405 can easily buffer the buffer plate 16 through the first buffer frame 401, and the surface of the limiting block 6 can contact the inside of the sliding groove 14, thereby making it easy for the limiting block 6 to limit the buffer plate 16 through the sliding groove 14, thus achieving the effect of limiting and buffering the buffer plate 16.

[0040] Specifically, such as Figure 3 , Figure 5 As shown, six rotating columns 7 are rotatably connected to the opposite side of the two limiting blocks 6, and the surface of the rotating columns 7 is in contact with the inside of the sliding groove 14.

[0041] Specifically, such as Figure 4 , Figure 5 As shown, an arc groove 8 is provided at the bottom inside the buffer groove 13, and the bottom of the limiting plate 404 extends into the interior of the arc groove 8 and is slidably connected to the interior of the arc groove 8.

[0042] In this embodiment: by making the surface of the rotating column 7 contact the inside of the sliding groove 14, the limiting block 6 can be easily moved inside the sliding groove 14 through the rotating column 7, so that the surface of the limiting plate 404 is slidably connected to the inside of the arc groove 8, thereby making it convenient for the limiting plate 404 to limit the arc plate 403 through the arc groove 8, thus achieving the effect of limiting the arc plate 403.

[0043] Specifically, such as Figure 4 , Figure 5 As shown, a protective plate 12 is fixedly connected between the bottoms of the two buffer grooves 13, and the top of the protective plate 12 is in contact with the bottom of the air cushion 405.

[0044] Specifically, such as Figure 5 As shown, four fixing blocks 3 are provided at the bottom of the frame 15. Four limiting rods 10 are slidably connected inside the fixing blocks 3. A second buffer frame 11 is fixedly connected to the top of the fixing blocks 3. A partition 9 is fixedly connected between the tops of the four fixing blocks 3. The top of the partition 9 is fixedly connected to the bottom of the frame 15.

[0045] In this embodiment: by having the top of the protective plate 12 contact the bottom of the air cushion 405, the protective plate 12 can easily limit and protect the air cushion 405, and the surface of the limiting rod 10 can slide and connect with the inside of the fixing block 3, thereby making it easy for the fixing block 3 to limit the frame 15 through the second buffer frame 11 and the limiting rod 10, thus achieving the effect of auxiliary limiting of the frame 15.

[0046] Working principle: When conveying materials, the materials move through the connecting plate 201 to the material inclined block 202, and then to the top of the buffer plate 16. This facilitates the buffer plate 16 to drive the material inclined block 202 to rotate via the hinge 203. Under the limit of the limiting spring 204, the materials are facilitated to move through the roller 5, so that the bottom of the buffer plate 16 contacts the top of the first buffer frame 401. The first buffer frame 401, through the arc plate 403, drives the limiting plate 404 to move and adjust within the buffer groove 13. The limiting plate 404, through the arc groove 8, moves against the first buffer frame 401. 1. Limiting the position allows the first buffer frame 401 to compress the air inside the air cushion 405, forming pressure in the air cushion 405, thereby generating buffering force and effectively absorbing the impact force of the material. Under the limitation of the partition plate 9 and the second buffer frame 11, the frame 15 can move and buffer through the limit rod 10, thus facilitating the transport of materials by the conveyor belt 1. This solves the problem that existing buffer brackets cannot completely and effectively absorb the impact force of materials with large particle size, high drop, and high speed, resulting in the conveyor belt 1 still being subjected to a large impact and affecting its service life.

[0047] The above are merely preferred embodiments of the present utility model and are not intended to limit the present utility model. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
