Description

Technical Field

[0001] The utility model belongs to the technical field of belt conveyors, and in particular relates to a material unloading device for a belt conveyor. Background Art

[0002] In the process of recycling and reusing aluminum products, the collected aluminum products (such as cans, etc.) are first crushed, and the crushed materials are transported to the silo by belt conveyors for temporary storage. Then, impurities such as shredded paper mixed in them are separated and subsequently processed;

[0003] When the belt conveyor is conveying materials to the silo, the discharge end of the belt conveyor is set above the silo so that the conveyed materials fall into the silo. Since the crushed aluminum products will adhere to the surface of the belt, as the belt drives, they will fall off when they reach the lower end of the belt away from the silo, causing material waste and difficulty in cleaning. Summary of the invention

[0004] The utility model aims to solve the problem that in the process of conveying crushed aluminum waste to a silo by an existing belt conveyor, the material adheres to the belt surface and does not fall directly into the silo, but scatters around after leaving the top of the silo, causing waste and being difficult to clean. A belt conveyor unloading device is provided, which cleans the material adhered to the belt surface by a scraper and guides it to a first guide block by an inclined plate, and buffers it by the first guide block to avoid it from being scattered and guides it to fall into the silo.

[0005] In order to achieve the above purpose, the technical solution of the utility model is:

[0006] The discharging opening of the belt conveyor is an opening through the bottom of the belt conveyor and a discharging opening of the belt conveyor is connected with the discharging opening of the belt conveyor.

[0007] Preferably, connecting pieces are fixedly provided on both sides of the limit box, and the two connecting pieces are fixedly connected with long plates by bolts and nuts. A second material guide block is fixedly provided between the ends of the two long plates away from the limit box, and the second material guide block corresponds to the outlet of the discharge barrel. The material discharged from the discharge barrel is buffered and diverted by the second material guide block and then falls into the silo.

[0008] Preferably, both ends of the transmission roller at the discharge end of the belt conveyor are fixedly provided with a first connecting column, the first connecting column passes through the corresponding bracket plate and the side wall of the limit box and is fixedly connected to the second connecting column, the axes of the first connecting column and the second connecting column do not coincide, the second connecting column is rotatably connected with an L-shaped rod, a collision rod is fixedly provided between the two L-shaped rods, and an impact block is fixedly provided on the collision rod, the impact block is located below the middle of the inclined plate and is arranged close to the inclined plate, the rotation of the transmission roller drives the first connecting column to rotate, drives the second connecting column to rotate around the first connecting column, drives the L-shaped rod to swing, drives the collision rod to swing, drives the impact block to swing and hit the inclined plate to avoid residual material on the inclined plate.

[0009] Preferably, strip plates are fixedly arranged above both sides of the inclined plate, and the strip plates are arranged parallel to the bracket plates. The strip plates are used to limit the material on the inclined plate to prevent it from falling from both sides and ensure that it falls above the first guide block.

[0010] Preferably, the first material guide block and the second material guide block are both in the shape of a triangular prism, and are both located directly above the silo to ensure diversion and buffering of the materials falling thereon.

[0011] Through the above technical solution, the beneficial effects of the utility model are:

[0012] 1. The utility model scrapes the material adhered to the belt surface by a scraper arranged under the belt conveyor, so that the material falls on the inclined plate, and the inclined plate is tilted to make the material fall above the first guide block, and then falls into the silo after being diverted and buffered by the first guide block, effectively preventing the material adhered to the belt surface from leaving the silo as the belt rotates and spilling on the ground, causing problems of difficulty in cleaning and waste.

[0013] 2. The utility model provides a first material guide block and a second material guide block in the shape of a triangular prism to buffer the material that falls from the belt conveyor to the discharge end and the material that is cleaned out by the scraper, so as to prevent impurities in the material, such as paper scraps, from flying around, and at the same time ensure that the material falls into the silo to prevent it from splashing out of the silo above the silo. At the same time, the fallen material is diverted to prevent the material that falls into the silo from forming a separate material pile, resulting in the ineffective use of the space in the silo, and to prevent the material level at the corresponding discharge barrel position from being too high to affect subsequent material dropping.

[0014] 3. The utility model sets strip plates on both sides of the inclined plate to limit the material on the inclined plate, and transports the material to the top of the first guide block by holding the inclined plate, and then falls into the silo after being buffered by the first guide block, which effectively avoids the problem that when the material falls directly into the silo from both sides of the inclined plate, the material falls in a floating state in the air due to the high falling position of the material, and then the material cannot fall into the silo, causing waste and difficulty in cleaning.

[0015] 4. The utility model drives the first connecting column to rotate through the transmission roller at the discharge end of the belt conveyor, and then drives the second connecting column to rotate around the first connecting column, drives the L-shaped rod and the impact rod to swing circumferentially, realizes the uninterrupted impact of the impact block on the inclined plate, realizes the vibration discharge of the inclined plate, ensures that the material falls above the first guide block, and avoids material residue on the inclined plate.

DETAILED DESCRIPTION

[0022] The utility model is further described below in conjunction with the accompanying drawings and specific embodiments:

[0023] like Figure 1 to Figure 5As shown, the present embodiment provides a belt conveyor unloading device, comprising a belt conveyor 1, which is arranged between two bracket plates 2, comprising a transmission roller and a belt, the transmission roller is driven to rotate by a motor and a reducer (not shown in the figure), and drives the belt to rotate for conveying materials to a silo (not shown in the figure), and also comprises a plurality of connecting rods 3, the discharging end of the belt conveyor 1 is fixedly sleeved with a limit box 4, the side and the lower side of the limit box 4 close to the belt conveyor 1 are both set as open structures, a discharging cylinder 5 is arranged below the limit box 4, the limit box 4 is connected with the discharging cylinder 5, the lower opening of the limit box 4 is connected with the discharging cylinder 5, the material at the discharging end of the belt conveyor 1 is limited by the limit box 4 to avoid splashing, and at the same time ensure that it falls into the discharging cylinder 5, an inclined plate 6 is arranged below the belt conveyor 1, the The upper end of the inclined plate 6 is fixedly connected to the bracket plate 2, and the inclined plate 6 is used to receive the materials that are cleaned and dropped after the belt of the belt conveyor 1 adheres. Two baffles 7 are arranged under the belt conveyor 1, and the two baffles 7 are fixedly connected to the bracket plate 2 through the connecting rod 3. A first guide block 8 is fixedly arranged between the two baffles 7, and the upper side of the baffle 7 arranged close to the inclined plate 6 is fixedly connected to the lower end of the inclined plate 6. The cross-section of the first guide block 8 is triangular, and the vertex of the triangle faces upward and is located in the middle of the baffle 7. The material on the inclined plate 6 falls above the first guide block 8 and falls into the silo after being diverted and buffered by the first guide block 8. On the one hand, the material is diverted to ensure that the material falls more evenly in the silo, and the silo space is fully and effectively utilized. On the other hand, a single material pile is avoided in the silo, resulting in too high a material level that affects the subsequent feeding of the silo.

[0024] A scraper 9 is fixedly provided above the inclined plate 6 by the connecting rod 3. The scraper 9 is a brush or a scraper, which is used to clean the material adhered to the belt surface of the belt conveyor 1, so that the material adhered to the belt is cleaned by the scraper 9 during the reverse conveying process after passing through the discharge cylinder 5, and the material on the lower side of the belt is scraped and cleaned so that it falls onto the inclined plate 6, and slides to the top of the first guide block 8 as the inclined surface of the inclined plate 6 is inclined.

[0025] Connecting pieces 10 are fixedly arranged on both sides of the limit box 4, and the two connecting pieces 10 are fixedly connected with a long plate 11 by bolts and nuts. A second material guide block 12 is fixedly arranged between the ends of the two long plates 11 away from the limit box 4. The second material guide block 12 corresponds to the outlet of the discharge barrel 5. By loosening the bolts and nuts, the angle of the long plate 11 can be adjusted to ensure that the material falling from the discharge barrel 5 falls on the second material guide block 12 and then falls into the material bin. The second material guide block 12 is a triangular prism or a conical structure. On the one hand, the material falling through the discharge barrel 5 passes through the second The buffering of the guide block 12 can effectively prevent the material from being scattered or splashed when it falls from a higher position, causing part of the material or lighter impurities such as paper in the material to be scattered, and then the material flies out of the silo or causes environmental problems, ensuring that the material falls directly into the silo from a lower position after being buffered by the second guide block 12. On the other hand, the material falling from the discharge barrel 5 is diverted by the second guide block 12 to avoid the formation of a separate material pile at the position corresponding to the discharge barrel 5, resulting in the problem that the material level is too high and the space in the silo that does not correspond to the position of the discharge barrel 5 cannot be utilized.

[0026] The transmission rollers at the discharging end of the belt conveyor 1 are fixedly provided with first connecting columns 13 at both ends, and the first connecting columns 13 penetrate the corresponding bracket plate 2 and the side wall of the limit box 4 and are fixedly connected to the second connecting columns 14. The axes of the first connecting columns 13 and the second connecting columns 14 do not coincide with each other. When the transmission rollers at the discharging end of the belt conveyor 1 are working, they drive the two first connecting columns 13 to rotate, and then drive the corresponding second connecting columns 14 to rotate around the axis of the first linking columns 13. The second connecting column 14 is rotatably connected with an L-shaped rod 15, and a striker rod 16 is fixedly provided between the two L-shaped rods 15. When the second connecting column 13 rotates, the L-shaped rod 15 and the striker rod 16 are driven to swing circumferentially. An impact block 17 is fixedly provided on the striker rod 16, and the impact block 17 is located below the middle part of the inclined plate 6 and is arranged close to the inclined plate 6. The striker rod 16 drives the impact block 17 to swing to achieve uninterrupted impact on the inclined plate 6, thereby achieving vibration unloading of the inclined plate 6, ensuring that the material above the inclined plate 6 slides more thoroughly to the first guide block 8, and avoiding residual material on the inclined plate 6.

[0027] Strip plates 18 are fixedly arranged above both sides of the inclined plate 6. The strip plates 18 are arranged parallel to the bracket plate 2. The strip plates 18 prevent the materials on the inclined plate 6 from falling directly into the silo from both sides of the inclined plate 6 during sliding or vibration.

[0028] The first material guide block 8 and the second material guide block 12 are both in the shape of a triangular prism, and are both located directly above the silo. The first material guide block 8 and the second material guide block 12 are used to buffer and divert the falling material, thereby ensuring that the material fully falls into the silo and that the material fully fills the space inside the silo.

[0029] When in use, the material is transported to the limit box 4 through the belt conveyor 1, and falls into the silo through the discharge barrel 5. During this process, the material at the discharge end of the belt conveyor 1 is first limited by the limit box 4 to prevent the material from being scattered, and a second guide block 12 is arranged below the discharge barrel 5. The material falling from the discharge barrel 5 is buffered and diverted by the second guide block 12, and falls into the silo fully and evenly.

[0030] During the conveying process, a part of the material will adhere to the surface of the belt, and as the belt rotates, it will be transported along the lower side of the belt conveyor 1 to the feeding end of the belt conveyor 1. If the material falls on the ground after leaving the top of the silo, it will cause material waste on the one hand, and on the other hand, it is difficult to clean the material that falls on the ground. Therefore, after the material adhered to the surface of the belt leaves the position of the discharge barrel 5, it is cleaned by the scraper 9, so that the material adhered to the surface of the belt falls on the inclined plate 6. As the drive roller at the discharge end of the belt conveyor 1 rotates, the two first connecting columns 13 are driven to rotate. Since the second connecting column 14 is fixed It is arranged at the end of the first connecting column 13, and the axes of the first connecting column 13 and the second connecting column 14 do not coincide, the second connecting column 14 rotates around the axis of the first connecting column 13, and one end of an L-shaped rod 15 is sleeved on the second connecting column 14, driving the L-shaped rod 15 to swing, driving the impact rod 16 and the impact block 17 to swing, and the impact block 17 continuously hits the inclined plate 6 when swinging, so that the inclined plate 6 realizes vibration unloading, ensuring that the material falling on the inclined plate 6 fully slides down, and falls on the first guide block 8 between the two baffles 7, and after being buffered and diverted by the first guide block 8, it fully falls into the silo.

[0031] The embodiments described above are only preferred embodiments of the present invention and are not intended to limit the scope of implementation of the present invention. Therefore, any equivalent changes or modifications made based on the structures, features and principles described in the patent scope of the present invention should be included in the patent application scope of the present invention.
