Description

Technical Field

[0001] This invention relates to the field of material conveying technology, and in particular to a conveying device for conveying materials at large angles. Background Technology

[0002] In industrial production, such as mining operations, due to geographical limitations, tunnels are gradually dug deeper within a small area. During the deep digging process, soil, gravel, and other materials need to be transported outside the tunnel. In many situations, conditions make it unsuitable to use trucks for transportation. Similarly, in the construction industry, such as foundation pit excavation, the entire foundation pit is small in size, making trucks unable to transport materials. During the excavation process, there is a continuous need to transport soil, gravel, and other materials.

[0003] To facilitate the transport of excavated soil and gravel, a material conveyor is used to transport the soil and gravel from the deep pit. Due to the height difference between the pit and the ground, the conveyor needs to be tilted at a certain angle during the material transport process. To prevent the material from sliding down during transport, the base belt, partitions, and sidewalls on the conveyor work together to form a conveyor box. The material is transported with the cooperation of the base belt, partitions, and sidewalls. However, the transported material has high viscosity, causing it to stick to the belt. Due to the obstruction of the partitions and sidewalls, it is inconvenient to clean the material on the belt. Summary of the Invention

[0004] The purpose of this invention is to solve the shortcomings of existing technologies where materials are conveyed using a base belt, partitions, and sidewalls, and where it is inconvenient to clean the materials on the belt due to the obstruction of the partitions and sidewalls. Therefore, this invention proposes a conveying device for conveying materials at large angles.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0006] Design a conveying device for large-angle conveying, including a first frame, a second frame fixedly connected to the upper end of the first frame, two parallel rotating rollers rotatably connected to the second frame, two symmetrically arranged transmission belts connected between the two rotating rollers, a plurality of first connecting rods equally spaced along the length direction between the two transmission belts, a material box connected to each first connecting rod, a rotating shaft rotatably connected to the first frame below the head roller, a first scraper for cleaning the conveyor belt connected to the rotating shaft, the first scraper being connected to the first frame via a first spring.

[0010] Preferably, the elastic cleaning block is an elastic sponge block.

[0011] Preferably, the second frame is connected to a smoothing mechanism to improve the conveying effect of the material box. The smoothing mechanism includes two parallel fixed seats, both of which are fixedly connected to the second frame. Each fixed seat is slidably connected to a first movable plate. One end of each of the two first movable plates is fixedly connected to the same second scraper, which is in contact with the material box. Both sides of the bottom end of the second scraper are fixedly connected to baffles, one side of each baffle is in contact with the outer wall of the material box. The other ends of the two first movable plates are fixedly connected to the same first connecting plate. The upper end of the first connecting plate is connected to a second spring, one end of which is fixedly connected to the second frame.

[0012] Preferably, the second scraper is inclined downwards toward the material box.

[0013] Preferably, the first movable plate is connected to an anti-blocking mechanism to prevent the conveyed material from accumulating between the baffle and the second scraper. The anti-blocking mechanism includes two symmetrically arranged guide plates. Each guide plate is slidably inserted into a corresponding first movable plate. One end of each guide plate is fixedly connected to a second movable plate. Each second movable plate is fixedly connected to a third spring. One end of each third spring is fixedly connected to a corresponding first movable plate. One end of each second movable plate is fixedly connected to a push plate.

[0028] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments.

[0029] Example 1: Refer to Figure 1-5A conveying device for large-angle conveying includes a first frame 1. Several legs 2 are evenly spaced along the length of the bottom end of the first frame 1. A head roller 3 is rotatably connected to one end of the first frame 1, and a tail roller 4 is rotatably connected to the other end. A conveyor belt 5 connects the head roller 3 and the tail roller 4. A drive motor 6 for rotating the head roller 3 is connected to the first frame 1. A second frame 7 is fixedly connected to the upper end of the first frame 1. Two parallel rotating rollers 8 are rotatably connected to the second frame 7. One of the rotating rollers 8 is connected to the output end of the drive motor 6 via a belt drive component 10. Two symmetrically arranged transmission belts 9 are connected between the two rotating rollers 8. The transmission belts 9 are one of a transmission belt, chain, or wire rope. Several first connecting rods 11 are connected at equal intervals along the length of the first frame 9. Each first connecting rod 11 is connected to a material box 12. The material box 12 is in contact with the upper end of the conveyor belt 5. A rotating shaft 14 is rotatably connected to the first frame 1 below the head roller 3. A first scraper 15 for cleaning the conveyor belt 5 is connected to the rotating shaft 14. The first scraper 15 is connected to the first frame 1 through a first spring 16. Several first springs 16 are provided and are distributed at equal intervals along the length of the first scraper 15. A guide hopper 13 is connected to the second frame 7 above the tail roller 4. A support frame 17 is fixedly connected to the first scraper 15. An elastic cleaning block 18 is fixedly connected to the upper end of the support frame 17. The elastic cleaning block 18 is in contact with the conveyor belt 5. The elastic cleaning block 18 is an elastic sponge block.

[0030] Working principle:

[0031] Several support legs 2 support and fix the first frame 1, so that the first frame 1 maintains a certain tilt angle. After the drive motor 6 starts, it drives the head roller 3 to rotate. The head roller 3 drives the tail roller 4 to rotate through the conveyor belt 5. With the cooperation of the head roller 3 and the tail roller 4, the conveyor belt 5 is in a taut state. At the same time, the output end of the drive motor 6 drives the rotating roller 8 to rotate through the belt drive component 10. The rotating roller 8 drives the transmission belt 9 to rotate. The transmission belt 9 synchronously drives the first connecting rod 11 to rotate. The first connecting rod 11 drives the material box 12 to rotate. When the material box 12 rotates to the bottom of the rotating roller 8, it presses and contacts the upper end of the conveyor belt 5. At this time, the middle area of ​​the conveyor belt 5 is concave downward and the two sides are raised upward. A loading area is formed between the material box 12 and the conveyor belt 5. The material box 12 and the conveyor belt 5 move synchronously.

[0032] Material is fed into the guide hopper 13, and the material in the guide hopper 13 falls into the loading area. The loading area limits the material. After being limited, the material moves with the conveyor belt 5 towards the head roller 3. When the material moves to the head roller 3, the material box 12 rotates upward and separates from the conveyor belt 5, causing the material to fall from the head roller 3. After the material box 12 rotates upward, it is located above the conveyor belt 5. The material adhering to its surface falls onto the conveyor belt 5 under its own gravity.

[0033] After the conveyor belt 5 releases the material from the head roller 3, it continues to rotate to the bottom of the head roller 3. At this time, the conveyor belt 5 comes into contact with the first scraper 15. The first spring 16 provides elastic support for the first scraper 15, keeping the two in a state of compression contact. When the conveyor belt 5 moves, it slides relative to the first scraper 15, thereby scraping off the material adhering to the belt and achieving the initial cleaning. After being cleaned by the first scraper 15, the conveyor belt 5 continues to come into contact with the elastic cleaning block 18, which performs a second cleaning on the belt surface, significantly improving the cleaning effect.

[0034] During the material conveying process, the conveyor belt 5 and the material box 12 work together. After the material is released, the conveyor belt 5 and the material box 12 separate and reset. At this time, the material box 12 and the conveyor belt 5 are completely separated, so that the belt is fully exposed. The material adhering to the material box 12 automatically falls off under the action of gravity. The exposed conveyor belt 5 can be fully cleaned by the first scraper 15. The design of separating the conveyor belt 5 and the material box 12 makes the surface of the conveyor belt 5 unobstructed, which is convenient for cleaning operations and improves the maintainability of the entire conveying equipment.

[0035] Example 2: Each time the material box 12 rotates to the point where the bottom end of the rotating roller 8 makes contact with the upper end of the conveyor belt 5, the material easily adheres to the contact surface between the material box 12 and the conveyor belt 5. With continuous feeding, the amount of material adhering to the contact surface between the material box 12 and the conveyor belt 5 gradually increases, thus affecting the coordination between the material box 12 and the conveyor belt 5 in limiting and conveying the material. (Refer to...) Figure 6-7As another preferred embodiment of the present invention, the difference from embodiment 1 is that a smoothing mechanism 19 for improving the conveying effect of the material box 12 is connected to the second frame 7. The smoothing mechanism 19 includes two parallel fixed seats 191, both of which are fixedly connected to the second frame 7. A first movable plate 192 is slidably connected to each fixed seat 191. The same second scraper 193 is fixedly connected to one end of the two first movable plates 192. The second scraper 193 is inclined downward toward the material box 12 and contacts the material box 12. Baffles 194 are fixedly connected to both sides of the bottom end of the second scraper 193. One side of each baffle 194 contacts the outer wall of the material box 12. The same first connecting plate 195 is fixedly connected to the other end of the two first movable plates 192. A second spring 196 is connected to the upper end of the first connecting plate 195. One end of the second spring 196 is fixedly connected to the second frame 7.

[0036] Working principle:

[0037] The second spring 196 pushes the first connecting plate 195 downward, and the first connecting plate 195 drives the first movable plate 192 to move downward. The first movable plate 192 moves smoothly under the guidance of the fixed seat 191, and drives the second scraper 193 to move downward, so that the bottom end of the second scraper 193 is pressed into contact with the material box 12.

[0038] During the movement of the material box 12, it slides relative to the second scraper 193. The second scraper 193 scrapes and cleans the side of the material box 12 that contacts the conveyor belt 5, keeping the contact surface clean, thereby ensuring that the cooperation between the material box 12 and the conveyor belt 5 can stably limit the conveying of materials.

[0039] In addition, during the scraping process, the baffle 194 limits the scraped material so that it falls into the material box 12, preventing the material from falling onto the transmission belt 9, thus not affecting the normal operation of the transmission belt 9 driving the rotating drum 8.

[0040] Example 3: When the second scraper 193 cleans the contact surface between the material box 12 and the conveyor belt 5, the scraped material tends to accumulate between the second scraper 193 and the baffle 194. As the material continues to increase, the material accumulated between the second scraper 193 and the baffle 194 pushes the second scraper 193 upward, creating a gap between the second scraper 193 and the material box 12, thereby reducing the cleaning effect of the second scraper 193 on the material box 12. (Refer to...) Figure 7-9In another preferred embodiment of the present invention, the difference from Embodiment 2 is that an anti-blocking mechanism 20 is connected to the first movable plate 192 to prevent the conveyed material from accumulating between the baffle 194 and the second scraper 193. The anti-blocking mechanism 20 includes two symmetrically arranged guide plates 201, each guide plate 201 being slidably inserted into the corresponding first movable plate 192. One end of each guide plate 201 is fixedly connected to a second movable plate 202, and each second movable plate 202 is fixedly connected to a third spring 203, one end of each third spring 203 being fixedly connected to the corresponding first movable plate 192. One end of each second movable plate 202 is fixedly connected to a push plate 204, one side of each push plate 204 passing through the corresponding baffle 194. A second connecting plate 205 is fixedly connected between the two first movable plates 192, and two sliding connections are provided on the second connecting plate 205. Parallel guide rods 206 are arranged, and a third movable plate 207 is fixedly connected between the bottom ends of the two guide rods 206. A third connecting plate 208 is fixedly connected to the upper end of the third movable plate 207. Steel ropes 209 are fixedly connected to both sides of the third connecting plate 208. One end of each steel rope 209 is fixedly connected to the corresponding second movable plate 202. A second connecting rod 2010 is fixedly connected to both sides of the upper end of the second connecting plate 205. A guide wheel 2011 is connected to one end of each second connecting rod 2010. Each guide wheel 2011 is in contact with the upper end of the corresponding steel rope 209. A fixing plate 2012 is fixedly connected to both sides of each second connecting rod 2010. A limit ring 2013 is fixedly connected to one end of each fixing plate 2012. The steel rope 209 passes through the limit ring 2013. The guide wheel 2011 and the limit ring 2013 are on the same straight line.

[0041] Working principle:

[0042] As the material box 12, which is separated from the conveyor belt 5, rotates upward, it pushes the third movable plate 207 to move upward. Under the guidance of the second connecting rod 2010, the third movable plate 207 moves smoothly and drives the third connecting plate 208 to move upward. After the third connecting plate 208 moves upward, it pulls the steel rope 209. After being guided by the guide wheel 2011, the steel rope 209 pulls the second movable plate 202 horizontally, causing the two second movable plates 202 to move towards each other. The fixed plate 2012 fixes the limiting ring 2013, and the limiting ring 2013 limits the steel rope 209 to prevent the steel rope 209 from separating from the guide wheel 2011.

[0043] The second movable plate 202 moves smoothly under the guidance of the guide plate 201. After the two second movable plates 202 move towards each other, they pull the third spring 203. The third spring 203 is stretched and generates elastic force. At the same time as the two second movable plates 202 move towards each other, they drive the push plate 204 to move. The push plate 204 gradually extends between the second scraper 193 and the baffle 194 to push the material accumulated between them, so that the accumulated material falls into the material box 12. This can prevent the material from accumulating between the second scraper 193 and the baffle 194, so as not to push the second scraper 193 to move upward. It can maintain the squeezing strength of the second scraper 193 on the contact surface between the material box 12 and the conveyor belt 5, thereby maintaining its cleaning effect.

[0044] When the material box 12 is misaligned and separated from the third movable plate 207, the third movable plate 207 moves downward and resets under its own gravity. At the same time, the elastic force of the third spring 203 drives the second movable plate 202 to reset. The second movable plate 202 then pushes the push plate 204 to reset. As the conveyor belt 5 drives the material box 12 to rotate upward continuously, the material box 12 continuously pushes the third movable plate 207, so that the push plate 204 continuously pushes the material accumulated between the second scraper 193 and the baffle 194 forward, preventing the material from accumulating between the second scraper 193 and the baffle 194.

[0045] The above description is only a preferred embodiment of the present invention, but the scope of protection of the present invention is not limited thereto. Any equivalent substitutions or modifications made by those skilled in the art within the scope of the technology disclosed in the present invention, based on the technical solution and inventive concept of the present invention, should be covered within the scope of protection of the present invention.
