Description

Technical Field

[0001] The utility model relates to the technical field of conveyors, in particular to a blanking mechanism for the tail of a flat conveyor belt. Background Technique

[0002] A chain plate conveyor is a continuous conveying device with a chain as the traction part and a chain plate as the bearing surface. The motor drives the sprocket to rotate through a speed reducer, the sprocket drives the chain to move, and the chain plate conveys materials forward along with the movement of the chain. The materials are placed on the chain plate and are conveyed from one end of the conveyor to the other end under the drive of the chain plate.

[0003] In the existing chain plate conveyor, the distance between each conveying plate becomes larger at the tail turning point. When conveying smaller particles such as grains, the smaller particles at the tail end will fall into the gaps between the chain plates, resulting in material loss, reducing the conveying efficiency, and increasing the production cost. Moreover, the small particles falling into the gaps may cause wear to the chain plates and chains, affecting the service life of the equipment. Content of the Utility Model

[0004] The utility model aims to provide a blanking mechanism for the tail of a flat conveyor belt to solve the problems put forward in the above background technique.

[0005] To achieve the above object, the utility model provides the following technical solution:

[0006] A blanking mechanism for the tail of a flat conveyor belt includes a housing. The housing is rotatably connected with a first rotating shaft and a second rotating shaft. The housing is connected with a motor, and the output end of the motor is connected with the first rotating shaft. The first rotating shaft and the second rotating shaft are respectively connected with a first sprocket and a second sprocket. The first sprocket and the second sprocket are jointly movably connected with a chain plate. The housing is provided with a chute, the side wall of the chute is slidably connected with a connecting block, the bottom wall of the chute is connected with a positioning rod, the connecting block is slidably connected with the positioning rod, the connecting block is connected with a transition plate and a positioning block, and both the transition plate and the positioning block are in contact with the chain plate.

[0007] Preferably, the positioning rod is connected with a limiting block, and a spring is sleeved outside the positioning rod. The two ends of the spring are respectively in contact with the limiting block and the connecting block.

[0008] Preferably, the limiting block is detachably connected with the positioning rod.

[0009] Preferably, the side of the transition plate in contact with the chain plate is inclined.

[0010] Preferably, the motor is detachably connected with the housing, the first rotating shaft and the second rotating shaft are slidably connected with the housing, and the first sprocket and the second sprocket are respectively slidably connected with the first rotating shaft and the second rotating shaft.

[0011] Preferably, the first rotating shaft is detachably connected with a first limiting plate, and both ends of the second rotating shaft are detachably connected with second limiting plates.

[0012] Beneficial effects of this technical solution compared with the prior art:

[0013] (1) By providing a transition plate in this technical solution, when transporting small-particle materials such as grains, it can effectively prevent these small particles from falling into the gaps of the chain plates, thereby reducing material loss. This helps improve the conveying efficiency of the materials and reduce production costs. Avoiding small-particle materials from falling into the chain plate gaps can prevent wear on the chain plates and sprockets or cause equipment blockages. Reducing the accumulation of materials inside the equipment makes the cleaning work easier and reduces the workload and difficulty of cleaning. During the operation of the chain plate conveyor, due to various reasons, the height of the chain plates may change slightly. By providing a chute, a connecting block, and a positioning block, the transition plate can automatically adapt to this change and always maintain contact with the chain plates. This improves the adaptability of the equipment and reduces the frequent adjustments and maintenance required due to chain plate changes. Ensuring seamless connection during the transfer of materials from the chain plates to the transition plate and the sliding of materials from the transition plate, avoiding materials getting stuck in the gaps, and ensuring the continuity and stability of the conveying.

[0014] (2) By providing a spring, it always provides appropriate pressure to the connecting block, ensuring that the transition plate always maintains close contact with the surface of the chain plates. Even when vibrations occur during the operation of the chain plate conveyor or there are slight changes in the height of the chain plates, the pressure of the spring can enable the connecting block to adjust its position in a timely manner to maintain the contact state of the transition plate.

[0015] (3) By providing a detachable limiting block, when the transition plate or the connecting block is damaged, worn, or malfunctioning, it can be conveniently removed from the housing for repair or replacement. There is no need to disassemble the entire chain plate conveyor on a large scale, saving repair time and labor costs.

[0016] (4) By providing an inclined side surface of the transition plate, the height difference between the transition plate and the chain plates is eliminated, providing a smooth transition channel for the materials. The materials can naturally slide from the chain plates onto the transition plate without being blocked or stuck due to a sudden change in height. This helps improve the conveying efficiency of the materials and reduce losses and waste during the transfer process.

[0017] (5) By setting a detachable motor, a first rotating shaft and a second rotating shaft that are slidably connected to the housing, and a first sprocket and a second sprocket that are slidably connected to the first rotating shaft and the second rotating shaft, the wear conditions, connection states, etc. of each component can be inspected more intuitively, potential problems can be discovered in a timely manner and processed, and the probability of equipment failure can be reduced. Moreover, during the installation of the equipment, the detachable structure makes the installation process more flexible. By setting a first limiting plate and a second limiting plate, the positions of the first rotating shaft and the second rotating shaft in the housing can be effectively restricted, ensuring that the rotating shafts will not slide out of the housing due to factors such as vibration and external impact during rotation, maintaining the normal operation of the equipment, and avoiding equipment failures and production interruptions caused by the displacement of the rotating shafts.

Detailed Description of the Preferred Embodiments

[0022] The present utility model will be further described in detail below with reference to the drawings and embodiments:

[0023] As Figures 1-3 shown, a blanking mechanism for the tail of a flat conveyor belt includes a housing 2. A first rotating shaft 4 and a second rotating shaft 5 are rotatably connected to the side wall of the housing 2. The first rotating shaft 4 is located at the front end of the housing 2, and the second rotating shaft 5 is located at the tail of the housing 2. A motor 13 is connected to the outer side wall of the housing 2, and the output end of the motor 13 is connected to the first rotating shaft 4. A first sprocket 3 and a second sprocket 6 are respectively connected to the first rotating shaft 4 and the second rotating shaft 5, and a chain plate 1 is jointly movably connected to the first sprocket 3 and the second sprocket 6. The transmission principle between the chain plate 1 and the sprockets belongs to the prior art and will not be elaborated here. As Figures 2-3As shown in the figure, a chute 15 is provided on the inner side wall of the tail of the housing 2. A connecting block 8 is slidably connected to the side wall of the chute 15. A positioning rod 12 is connected to the bottom wall of the chute 15. The connecting block 8 is slidably connected to the positioning rod 12. The top end of the positioning rod 12 is detachably connected with a limiting block 10. A spring 11 is sleeved on the outer side of the positioning rod 12. The two ends of the spring 11 are respectively in contact with the limiting block 10 and the connecting block 8. A positioning block 9 is rotatably connected to the side wall of the connecting block 8. The longitudinal section of the positioning block 9 is circular. The left and right groups of connecting blocks 8 are jointly connected with a transition plate 7.

[0024] As Figure 1 shown in the figure, the tail of the longitudinal section of the transition plate 7 is arc-shaped. The transition plate 7 completely covers the gap between the chain plates 1 at the turning position of the tail of the conveying device. Both the transition plate 7 and the positioning block 9 are in contact with the chain plate 1. The lowest point of the positioning block 9 is flush with the bottom surface of the end of the transition plate 7 in contact with the chain plate 1. When the chain plate 1 is driven, the positioning block 9 rotates relative to the connecting block 8 under the action of the frictional force between the positioning block 9 and the chain plate 1 and is in contact with the surface of the chain plate 1. When the height of the chain plate 1 slightly increases, the chain plate 1 squeezes the positioning block 9 upward, causing the connecting block 8 to slide upward along the positioning rod 12 and squeezing the spring 11; when the height of the chain plate 1 slightly decreases, the spring 11 squeezes the connecting block 8, causing the connecting block 8 to slide downward until the positioning block 9 is in contact with the chain plate 1. When there is a slight change in the height of the chain plate 1, the part of the transition plate 7 flush with the lowest point of the positioning block 9 always remains in contact with the upper surface of the chain plate 1. The side of the end of the transition plate 7 in contact with the chain plate 1 is inclined. The material on the chain plate 1 can be smoothly transferred to the transition plate 7 through the inclined surface. The material just transferred from the chain plate 1 pushes the material located at the tail of the transition plate 7, causing the material to fall from the transition plate 7 to the conveying end position.

[0025] As Figures 1-2 shown in the figure, the motor 13 is detachably connected to the housing 2. Both ends of the first rotating shaft 4 and the second rotating shaft 5 are slidably connected to the side wall of the housing 2. The first sprocket 3 and the second sprocket 6 are respectively slidably connected to the first rotating shaft 4 and the second rotating shaft 5. Convex strips are provided on the parts of the first rotating shaft 4 and the second device located inside the housing 2. Holes that can be closely attached to the first rotating shaft 4 and the second rotating shaft 5 are respectively provided at the central positions of the first sprocket 3 and the second sprocket 6. When the first rotating shaft 4 and the second rotating shaft 5 rotate, the convex strips can prevent the first rotating shaft 4 and the second rotating shaft 5 from rotating relative to the first sprocket 3 and the second sprocket 6, so that the first sprocket 3 and the second sprocket 6 rotate together. A first limiting plate 14 is detachably connected to the end of the first rotating shaft 4 away from the motor 13. Second limiting plates 16 can be detachably connected to both ends of the second rotating shaft 5. Both the first limiting plate 14 and the second limiting plate 16 are in contact with the outer side wall of the housing 2 to prevent the first rotating shaft 4 and the second rotating shaft 5 from sliding relative to the housing 2 due to the vibration during the operation of the conveying device.

[0026] The specific implementation process is as follows:

[0027] During use, start the motor 13, and feed materials to the front end of the conveying device. The materials move towards the tail of the conveying device along with the moving chain plate 1. Under the action of the spring 11, the transition plate 7 is always in close contact with the moving chain plate 1. The materials are smoothly transferred onto the transition plate 7 along the inclined side of the transition plate 7, and then fall from the transition plate 7 to the end position.

[0028] During maintenance, the limit block 10 can be removed from the positioning rod 12, and the spring 11 can be removed from the positioning rod 12 for replacement. Or the connecting block 8 together with the transition plate 7 and the positioning block 9 can be removed from the housing 2 for replacement or repair. When maintaining the plate chain, sprocket or rotating shaft, the first limit plate 14 can be removed from the first rotating shaft 4. Then, remove the motor 13 from the housing 2, and pull the motor 13 to draw out the first rotating shaft 4 from the housing 2. At the same time, the first sprocket 3 also slides off the first rotating shaft 4. Remove any one of the second limit plates 16 from the second rotating shaft 5, and pull the other second limit plate 16 to draw out the second rotating shaft 5 from the housing 2. At the same time, the second sprocket 6 also slides off the second rotating shaft 5. At this time, each component can be maintained or replaced.

[0029] The above are only embodiments of the present invention. Specific technical solutions and / or common knowledge such as characteristics well known in the art are not described in detail here. It should be noted that for those skilled in the art, without departing from the technical solution of the present invention, several deformations and improvements can be made, which should also be regarded as the protection scope of the present invention, and these will not affect the implementation effect of the present invention and the practicability of the patent. The protection scope required by this application should be based on the content of its claims, and the specific implementation manners described in the specification can be used to interpret the content of the claims.
