The material blockage will also damage the belt, causing economic losses and affecting the transportation of materials. Utility Model Content

[0004] In order to improve the above problems, the present application provides an automatic anti-overflow device for a belt conveyor.

[0005] The present application provides an automatic anti-overflow device for a belt conveyor adopts the following technical solution:

[0006] A belt conveyor automatic anti-overflow device includes a frame and a discharge barrel. The discharge barrel is installed on the frame. A belt conveys materials into the discharge barrel. A micro-stroke switch is installed on the frame. The micro-stroke switch is connected to the emergency stop switch of the belt conveyor. An overflow hole is opened on the discharge barrel. A movable door is rotatably connected to the discharge barrel. The movable door is located at the mouth of the overflow hole. The micro-stroke switch and the movable door are in contact with each other.

[0007] By adopting the above technical solution, the operator can transport the material into the discharge barrel through the belt. When the material in the discharge barrel is blocked, the material in the discharge barrel will gradually accumulate and accumulate to the height of the opening of the overflow hole, so that the material comes into contact with the movable door and pushes the movable door open. The movable door can trigger the micro-stroke switch, thereby causing the belt conveyor to stop suddenly, reducing the situation where the material continues to enter the discharge barrel and reducing the possibility of material waste. The operator can clean the blockage in the discharge barrel, reducing the possibility of material damaging the belt, and facilitating the transportation of materials.

[0008] Preferably, the cross-sectional area of ​​the movable door is larger than the cross-sectional area at the opening of the overflow hole.

[0009] By adopting the above technical solution, when the material flows out from the overflow hole, since the cross-sectional area of ​​the movable door is larger than the cross-sectional area at the overflow hole mouth, the material will definitely come into contact with the movable door, thereby micro-moving the travel switch, facilitating the emergency stop of the belt conveyor.

[0010] Preferably, an inclined plate is fixedly connected to the outer wall of the discharge barrel and below the opening of the overflow hole, and the end of the inclined plate close to the opening of the overflow hole is higher than the end of the inclined plate away from the opening of the overflow hole. A collecting box is provided on the frame, and the collecting box is located at the end of the inclined plate away from the opening of the overflow hole.

[0011] By adopting the above technical solution, after the material flows out of the overflow hole, the material can fall onto the inclined plate under the action of gravity, and flow from the inclined plate to the collection box. The collection box can collect the outflowing material, reducing the possibility of material waste.

[0014] By adopting the above technical solution, the first support frame can provide support for the cylinder, and the piston rod of the cylinder can drive the movement of the sliding rod, so that the sliding rod moves close to the discharge port of the discharge barrel. The sliding rod can exert force on the material, reducing the possibility of material blockage in the discharge barrel, thereby facilitating the transportation of the material.

[0015] Preferably, a rotating rod is rotatably connected inside the discharge barrel, the rotating rod is located above the discharge port of the discharge barrel, the rotating rod is in contact with the inner wall of the discharge barrel, and a second control component for controlling the rotation of the rotating rod is provided on the discharge barrel.

[0016] Preferably, the second control component is a motor, a second support frame is fixedly connected to the outer wall of the discharge barrel, the motor is installed on the second support frame, and the output shaft of the motor is fixedly connected to the rotation.

[0017] By adopting the above technical solution, the second support frame can provide support for the motor, and the output shaft of the motor can drive the rotation of the rotating rod. When the rotating rod rotates, it continues to fit with the inner wall of the discharge barrel. The rotating rod can scrape the inner wall of the discharge barrel, reducing the possibility of material adsorbing on the inner wall of the discharge barrel, thereby facilitating the transportation of materials.

[0018] Preferably, the rotating rod is provided with an inclined surface.

[0019] By adopting the above technical solution, since the rotating rod is provided with an inclined surface, the inclined surface can further facilitate the fitting of the rotating rod with the inner wall of the discharge barrel, and further facilitate the rotating rod to scrape the material on the inner wall of the discharge barrel.

[0021] 1. Through the arrangement of the micro-stroke switch, the overflow hole and the movable door, and by adopting the above technical solution, the operator can convey the material into the discharge barrel through the belt.

The movable door can trigger the micro-stroke switch, thereby causing the belt conveyor to stop suddenly, reducing the situation where the material continues to enter the discharge barrel and the possibility of material waste. The operator can clear the blockage of the discharge barrel, reducing the possibility of material damaging the belt, and facilitating the material transportation;

[0028] In order to make the purpose, features, and advantages of the invention of this application more obvious and easy to understand, the technical solutions in the embodiments of this application will be clearly and completely described below in conjunction with the drawings in the embodiments of this application. Obviously, the described embodiments are only part of the embodiments of this application, not all of the embodiments. Based on the embodiments in this application, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of this application.

[0029] The following is combined with Figure 1-4 This application is described in further detail.

[0030] The embodiment of the present application discloses an automatic anti-overflow device for a belt conveyor, such as Figure 1 As shown, it includes a frame 1 and a discharge barrel 2. The discharge barrel 2 is installed on the frame 1. The belt conveys the material into the discharge barrel 2 and discharges it from the discharge port of the discharge barrel 2. A micro travel switch 11 is fixedly installed on the frame 1, and the micro travel switch 11 is connected to the emergency stop switch of the belt conveyor.

[0031] like Figure 1 and 2 As shown, the wall of the discharge barrel 2 is provided with an overflow hole 21. A movable gate 22 is rotatably connected to the discharge barrel 2. The movable gate 22 is located at the opening of the overflow hole 21. The cross-sectional area of ​​the movable gate 22 is larger than the cross-sectional area at the opening of the overflow hole 21. The micro-stroke switch 11 abuts against the movable gate 22. When the belt conveyor conveys material into the discharge barrel 2, a blockage may occur in the discharge barrel 2. At this time, material continues to flow into the discharge barrel 2 and accumulates in the discharge barrel 2. When the material in the discharge barrel 2 accumulates to the opening of the overflow hole 21, the material flows out of the overflow hole 21 and exerts force on the movable gate 22, causing the movable gate 22 to rotate, thereby triggering the micro-stroke switch 11. The micro-stroke switch 11 can trigger the emergency stop switch of the belt conveyor, causing the belt to stop suddenly, thereby stopping the material conveying and preventing the material from continuing to accumulate in the discharge barrel 2. After the belt conveyor stops suddenly, the operator can clear the blockage in the discharge barrel 2, thereby facilitating the material conveying.

[0032] like Figure 1 and 2 As shown, an inclined plate 23 is fixedly attached to the outer wall of the lower barrel 2, below the opening of the overflow hole 21. The inclined plate 23 has an L-shaped cross-section, with the end of the inclined plate 23 near the opening of the overflow hole 21 higher than the end of the inclined plate 23 away from the opening of the overflow hole 21. A collection box 24 is fixedly mounted on the frame 1, located at the end of the inclined plate 23 away from the opening of the overflow hole 21. When material in the lower barrel 2 overflows from the overflow hole 21, it flows along the wall of the lower barrel 2 under the action of its own gravity, then flows onto the inclined plate 23 and along the length of the inclined plate 23, finally falling into the collection box 24. The collection box 24 collects the overflowed material, reducing the possibility of material waste.

[0033] like Figure 3 and 4As shown, the sliding rod 3 is slidingly connected in the discharging cylinder 2, the sliding rod 3 is inclinedly arranged, and the sliding rod 3 slides close to or away from the discharging port of the discharging cylinder 2. The first control member for controlling the sliding of the sliding rod 3 is arranged on the discharging cylinder 2, and the first control member is a gas cylinder 25. The piston rod of the gas cylinder 25 is fixedly connected with the sliding rod 3. The first support frame 26 is fixedly connected to the outer wall of the discharging cylinder 2, and the gas cylinder 25 is fixedly installed on the first support frame 26. The first support frame 26 can provide support for the gas cylinder 25, and ensure the stable installation of the gas cylinder 25. When the discharging cylinder 2 is blocked, the operator can drive the gas cylinder 25 to move the piston rod of the gas cylinder 25 to drive the sliding rod 3 to move, so that the sliding rod 3 moves close to the discharging port of the discharging cylinder 2. The sliding rod 3 can dredge the blocked material, thereby relieving the blockage in the discharging cylinder 2, without the need for manual dredging, and facilitating the conveying of the material.

[0034] As shown in Figure 3 and 4 The rotating rod 4 is rotatably connected in the discharging cylinder 2, the rotating rod 4 is located above the discharging port of the discharging cylinder 2, the rotating rod 4 is attached to the inner wall of the discharging cylinder 2, and the inclined surface 41 is arranged on the rotating rod 4. The second control member for controlling the rotation of the rotating rod 4 is arranged on the discharging cylinder 2, and the second control member is a motor 27. The output shaft of the motor 27 is fixedly connected with the rotating rod 4. The second support frame 28 is fixedly connected to the outer wall of the discharging cylinder 2, and the motor 27 is fixedly installed on the second support frame 28. The second support frame 28 can provide support for the motor 27, and ensure the stable installation of the motor 27. When the material is conveyed in the discharging cylinder 2, the material will be adsorbed on the inner wall of the discharging cylinder 2. At this time, the operator can drive the motor 27 to drive the output shaft of the motor 27 to rotate the rotating rod 4. The rotating rod 4 can scrape the inner wall of the discharging port of the discharging cylinder 2, and the material on the inner wall of the discharging cylinder 2 can be scraped off, thereby further reducing the possibility of blockage of the material, and facilitating the conveying of the material.

[0035] The implementation principle of the automatic anti-overflow device of the belt conveyor in the embodiment of the application is as follows:

[0036] When the material in the discharging cylinder 2 is blocked, the material flows out of the overflow hole 21 to exert a force on the movable door 22, thereby triggering the micro-travel switch 11 to make the belt conveyor stop urgently. The overflowed material can flow onto the inclined plate 23 and into the collecting box 24 for collection. The operator can drive the gas cylinder 25 to drive the sliding rod 3 to slide, so that the sliding rod 3 can exert a force on the blocked material to relieve the blockage. The operator can drive the motor 27 to drive the rotating rod 4 to rotate, so that the rotating rod 4 can scrape off the material on the inner wall of the collecting box 24, thereby facilitating the conveying of the material.

[0037] The above are all preferred embodiments of the present application, and are not intended to limit the scope of protection of the present application. Therefore, any equivalent changes made based on the structure, shape, and principle of the present application should be included in the scope of protection of the present application.
