Abstract
Description
Technical Field
[0001] This invention relates to the field of belt conveyor technology, and in particular to a non-powered material spreading and recycling belt conveyor. Background Technology
[0002] Material spillage is a common fault in belt conveyors, frequently occurring at the tail end, the concave section of the belt where it is suspended, and transfer points. Spillage at transfer points mainly occurs at the hopper and guide chute, while spillage at the tail end is primarily caused by material backflow, especially severe on steeply angled belts, resulting in a large amount of material spilling onto the ground below the tail end. Furthermore, the impact of large amounts of material in the chute onto the belt can also cause spillage on both sides. This spillage leads to transport losses and economic damage, while also increasing the amount of manual cleaning required.
[0003] The belt conveyor material recovery device disclosed in CN117302908A includes a conveying device, a conveyor belt installed inside the conveying device, and a recovery and cleaning mechanism located below the conveyor belt. The top of the conveying device has a feed inlet located above one end of the conveyor belt. A motor is mounted on the outer wall of the conveying device, and the output end of the motor is connected to the shaft end of the conveyor belt. The end of the conveying device forms a discharge outlet, and both the recovery and cleaning mechanism and the end of the conveyor belt extend to the discharge outlet. This invention installs a recovery and cleaning mechanism at the discharge outlet of the conveying device. A blowing mechanism within the recovery and cleaning mechanism can blow off the material adhering to the belt and blow it towards the discharge outlet. Some material falls onto the discharge belt, which continues to move and conveys the material on top towards the discharge outlet, achieving a secondary feeding effect. This reduces the amount of material adhering to the conveyor belt surface, reduces the trouble of subsequent cleaning, and improves the service life of the conveyor belt.
[0004] The above technical solution has some problems in practical application. The solution adds an extra conveyor belt below the original conveyor belt. Although it can solve part of the material drop problem, the extra conveyor belt requires an additional power mechanism, which is not only more expensive, but also affects the original conveyor belt.
[0005] Therefore, it is necessary to invent a non-powered material spreading and recycling belt conveyor to solve the above problems. Summary of the Invention

[0014] Preferably, a plurality of guide rollers are provided at equal intervals on the outside of the baffle. The guide rollers are in contact with the outside of the recovery belt, and the recovery belt moves along the end of the conveyor belt in a semi-circular trajectory under the guidance of the guide rollers.
[0015] The guide plate is designed with an inclined structure and is located at the bottom of the baffle. The guide plate is in contact with the surface of the recycling belt and can guide the material falling above the recycling belt toward the direction of the corrugated belt.
[0016] Preferably, the slide rod and the slide hole are provided, the slide rod is located on the outside of the baffle, the slide hole is located in the middle of the support frame, the slide rod can slide in the slide hole, and the slide rod and the slide hole can guide the baffle to slide horizontally to adjust its position relative to the conveyor belt;
[0017] The system includes a positioning plate, a positioning sleeve, and an adjusting screw. The positioning plate is located at one end of the slide rod, the positioning sleeve is located in the middle of the positioning plate, and the adjusting screw is located inside the positioning sleeve and rotatably positioned in the middle of the support frame. The adjusting screw and the positioning sleeve can adjust the position of the baffle.
[0018] Preferably, there are multiple transmission blocks located on the surface of the recovery belt, and the partitions on the surface of the conveyor belt can drive the recovery belt to move by pushing the transmission blocks;
[0019] The transmission block has an extension groove on the side near the direction of the recovery belt movement, and the extension groove is designed as an inclined structure to facilitate fastening with the partition.
[0020] Preferably, the movable rod is located at the end of the tensioning roller and connected to the tensioning roller via a bearing;
[0021] An extension frame is located outside the movable rod and fixed to the top of the support frame. Both ends of the extension frame are provided with inclined grooves, and the movable rod can slide in the grooves to adjust the position of the tension roller.
[0022] Preferably, the positioning seat is located at one end of the movable rod and has a strip-shaped pressure groove on its upper surface;

[0029] The technical effects and advantages of this invention are as follows:
[0030] 1. This invention provides a recovery belt installed below the conveyor belt. The recovery belt is in contact with the corrugated belt on the surface of the conveyor belt. When the conveyor belt is conveying materials, the corrugated belt on the surface of the conveyor belt can directly drive the recovery belt through friction, thereby achieving direct drive of the recovery belt. Furthermore, the horizontal width of the recovery belt is greater than that of the conveyor belt, so the material spilled on the conveyor belt can fall directly onto the recovery belt and be guided back to the top of the conveyor belt under the guidance of the recovery belt. This achieves material recovery from the conveyor belt without the need for an additional power mechanism. Moreover, the recovery belt can be directly installed at the bottom end of the conveyor belt based on the frame of the conveyor belt, with minimal impact on the original structure of the conveyor belt.
[0031] 2. This invention provides a baffle between the recovery belt and the conveyor belt. The corrugated belt on the surface of the conveyor belt and the baffle can form a closed channel. During the movement of the recovery belt, the spilled material can be driven through the closed channel, thereby achieving the purpose of recovering the spilled material. Furthermore, an inclined guide plate is provided at the bottom of the baffle. The guide plate can guide the spilled material to ensure that the spilled material can pass through the channel and return to the top of the conveyor belt. At the same time, the position of the baffle can be adjusted to ensure the closed state of the channel formed by the baffle and the corrugated belt.
[0032] 3. This invention provides a support frame on the outside of the recycling belt to support it. A tension roller is installed at the top of the support frame, and its position can be adjusted. This adjustment allows for adjustment of the tension of the recycling belt. Furthermore, the adjustment of the tension roller's position is guided by an inclined chute, allowing it to be adjusted towards the direction of the conveyor belt. This ensures that the recycling belt is pressed against the corrugated belt surface, thereby guaranteeing that the conveyor belt can drive the recycling belt during its movement.

[0044] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.
[0045] like Figures 1 to 10 As shown, the non-powered material spillage and recycling belt conveyor provided by the present invention is essentially a belt conveyor composed of a conveyor belt 1 and a recycling belt 2 distributed vertically. The conveyor belt 1 can convey materials through the partition 12 and the corrugated belt 13 on its surface. Furthermore, the conveyor belt 1 can drive the recycling belt 2 to move through the friction between the corrugated belt 13 and the recycling belt 2. The materials spilled on the conveyor belt 1 can fall onto the recycling belt 2, and the spilled materials can be conveyed by the recycling belt 2 to the top of the conveyor belt 1 to achieve the purpose of material spillage and recycling.
[0046] In terms of specific structural installation, the structural body can be constructed according to the inventive concept of this embodiment. In this embodiment, no special limitations are imposed.

[0053] Mounting base 32 is located at the bottom outer side of support frame 3. Mounting base 32 has a mounting screw 33 in the middle and two nuts in the middle. The two nuts are located on both sides of mounting base 32. The nuts can lock the position between mounting base 32 and mounting screw 33.
[0054] The connecting seat 34 is located at the bottom outer side of the frame 11 and is connected to the frame 11 by bolts. The connecting seat 34 is connected to one end of the mounting screw 33.
[0055] The baffle 4 is designed with an arc shape and is located between the conveyor belt 1 and the recovery belt 2. The inner wall of the baffle 4 is in contact with the outer side of the conveyor belt 1, and the edge of the baffle 4 is in contact with the surface of the recovery belt 2. The radius of the baffle 4 is greater than the distance between the conveyor belt 1 and the recovery belt 2. The baffle 4 and the corrugated belt 13 form a channel for guiding the material to be spread.
[0056] Guide rollers 41 are provided in multiple and equally spaced positions on the outside of baffle 4. Guide rollers 41 are in contact with the outside of the recovery belt 2.

[0057] The guide plate 42 is designed with an inclined structure and is located at the bottom of the baffle 4. The guide plate 42 is in contact with the surface of the recycling belt 2. The guide plate 42 can guide the material falling above the recycling belt 2 toward the corrugated belt 13.
[0058] The slide rod 43 is located on the outside of the baffle 4, and the slide hole 44 is located in the middle of the support frame 3. The slide rod 43 can slide in the slide hole 44. The slide rod 43 and the slide hole 44 can guide the baffle 4 to slide horizontally to adjust its position relative to the conveyor belt 1.
[0059] The positioning plate 45, the positioning screw sleeve 46, and the adjusting screw 47 are located at one end of the slide rod 43, the positioning screw sleeve 46 is located in the middle of the positioning plate 45, and the adjusting screw 47 is located inside the positioning screw sleeve 46 and rotatably located in the middle of the support frame 3. The adjusting screw 47 and the positioning screw sleeve 46 can adjust the position of the baffle 4.
[0060] Tensioning roller 5 is located on top of support frame 3 and is in contact with the inner side of recovery belt 2. Tensioning roller 5 can adjust the tension of recovery belt 2 and make it closely fit with corrugated belt 13. There are two tensioning rollers 5, and the two tensioning rollers 5 are set horizontally. The horizontal setting ensures that the recovery belt 2 passing through the tensioning roller 5 is parallel to the conveyor belt 1, thereby ensuring that the recovery belt 2 can be closely fitted with corrugated belt 13.
[0061] The movable rod 51 is located at the end of the tension roller 5 and is connected to the tension roller 5 via a bearing;
[0062] The extension frame 52 is located outside the movable rod 51 and fixed to the top of the support frame 3. Both ends of the extension frame 52 are provided with inclined grooves 53, and the movable rod 51 can slide in the grooves 53 to adjust the position of the tension roller 5.
[0063] The positioning seat 54 is located at one end of the movable rod 51 and has a strip-shaped pressure groove 55 on its upper surface;
[0064] The positioning bolts 56 are threaded onto the top of both sides of the extension frame 52. The bottom of the positioning bolts 56 can be squeezed through the pressure groove 55 to drive the tension roller 5 to move downward. When the positioning seat 54 is squeezed, it can move obliquely downward along the slide groove 53 to adjust the extension force of the recovery belt 2.
[0065] The guide hopper 6 is located above the support frame 3 and its bottom end corresponds to the middle of the conveyor belt 1. A connecting plate 61 is provided on one side of the bottom end of the guide hopper 6, and the connecting plate 61 is bolted to the top of the extension frame 52. The bottom end of the guide hopper 6 is provided with an inwardly converging side plate 62. The side plate 62 can ensure that the guide hopper 6 guides the material toward the middle of the conveyor belt 1.
[0066] When using the non-powered material spreading and recycling belt conveyor of this embodiment, the recycling belt 2 can be installed at the bottom end of the conveyor belt 1 through the support frame 3. The connecting seat 34 at the bottom outer side of the support frame 3 can be fixed to the frame 11 by bolts. By adjusting the position between the mounting screw 33 and the mounting seat 32, the position of the recycling belt 2 can be adjusted so that the recycling belt 2 can be tightly fitted with the corrugated belt 13 on the surface of the conveyor belt 1. By rotating the adjusting screw 47, the position of the positioning screw sleeve 46 and the baffle 4 can be adjusted so that the baffle 4 is fitted with the edge of the conveyor belt 1. At this time, the baffle 4 and the corrugated belt 13 on the surface of the conveyor belt 1 form a channel.
[0067] The material spilled above the conveyor belt 1 can fall onto the recovery belt 2, and the recovery belt 2 can follow the corrugated belt 13 under the action of friction, so that the recovery belt 2 follows the conveyor belt 1. At this time, the recovery belt 2 can drive the material spilling, and the material spilled can enter the channel between the baffle 4 and the corrugated belt 13 under the guidance of the guide plate 42. The material spilled follows the recovery belt 2 in the channel and is transported to the top of the conveyor belt 1. At this time, the material spilled can be recovered.
[0068] During the recycling process, the transmission block 21 in the middle of the surface of the recycling belt 2 can engage with the partition 12 on the surface of the conveyor belt 1. The partition 12 and the transmission block 21 can provide auxiliary traction for the recycling belt 2 to prevent slippage between the recycling belt 2 and the corrugated belt 13, thereby ensuring the recycling effect of the recycling belt 2 on the scattered material.
[0069] Finally, it should be noted that the above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features.
