Description

Technical Field

[0001] This utility model belongs to the technical field of conveyor belt equipment and relates to a conveyor belt feeding anti-crushing device. Background Technology

[0002] Belt conveyors are widely used in industries such as chemical, metallurgy, building materials, and food for the continuous quantitative transport of granular and powdery materials. During actual operation, due to material characteristics (such as moisture, viscosity, and particle size distribution) or uneven feeding, material can easily accumulate at the feed inlet or in the conveying channel. When the accumulated material reaches a certain height, it can cause a sudden increase in the load on the feeder's drive motor, even leading to "seal-off" conditions, resulting in equipment shutdown, motor burnout, or material waste. Currently, most cases involve on-site operators manually stopping the conveyor belt and handling the situation only when accumulation is observed. Failure to detect this in time can easily lead to equipment damage. Utility Model Content

[0003] The purpose of this invention is to address the problem that existing conveyor belts cannot promptly detect and handle material pushing when they are pushed, and to provide a conveyor belt anti-crushing device.

[0004] Therefore, the present invention adopts the following technical solution: A conveyor belt anti-crushing device includes a conveyor belt, a hopper above the conveyor belt, a discharge cylinder connected to the bottom of the hopper, a discharge port at the bottom of the side wall of the discharge cylinder facing the conveyor belt's feeding direction, a detection baffle hinged to the upper side of the discharge port, a detection rod inclined towards the conveyor belt's feeding direction on the upper side of the discharge port, a pressure sensor at the end of the detection rod away from the discharge port, and a controller connected to the conveyor belt.

[0005] Furthermore, the length of the detection rod is less than the length of the detection baffle.

[0006] Furthermore, the feeding cylinder is arranged vertically.

[0007] Furthermore, the hopper is equipped with multiple buffer rods arranged in parallel to each other.

[0008] Furthermore, the buffer rod is positioned horizontally.

[0009] Furthermore, a vibration motor is fixed to the side wall of the hopper.

[0010] Furthermore, the length of the detection baffle is less than the height of the discharge port.

[0011] The advantages of this utility model are as follows: a detection baffle is set at the material cylinder of the hopper, and a pressure sensor is set on one side of the detection baffle. When the material pushes, the material can make the detection baffle rotate and apply pressure to the pressure sensor, thereby detecting the material push in time. At this time, the controller can control the conveyor belt to stop running in time to avoid equipment damage. The structure is simple and the method of use is convenient. Attached Figure Description

Detailed Implementation

[0013] The present invention will now be described in detail with reference to the accompanying drawings: like Figures 1-3 As shown, a conveyor belt anti-crushing device includes a conveyor belt 1, a hopper 2 above the conveyor belt 1, and a vertically arranged discharge cylinder 3 connected to the bottom end of the hopper 2. Material in the hopper 2 can fall onto the conveyor belt 1 through the discharge cylinder 3. The bottom end of the discharge cylinder 3 is located near the upper surface of the conveyor belt 1, which prevents material from bouncing off the conveyor belt and falling outside the belt after falling onto it. A discharge port 4 is provided at the bottom of the side wall of the discharge cylinder 3, facing the conveying direction of the conveyor belt 1. After falling onto the conveyor belt 1 through the discharge cylinder 3, the material moves with the conveyor belt 1. During the movement, the material passes through the discharge port 4. The discharge port 4 prevents the discharge cylinder 3 from interfering with the material movement. A detection baffle 5 is hinged to the upper side of the discharge port 4. The length of plate 5 is less than the height of outlet 4. When the material at outlet 4 reaches the bottom of detection baffle 5, the material can contact detection baffle 5 during movement, causing detection baffle 5 to rotate. An detection rod 6 is provided on the upper side of outlet 4, facing the conveyor belt 1 and inclined. The length of detection rod 6 is less than the length of detection baffle 5. A pressure sensor 7 is provided at the end of detection rod 6 away from outlet 4. After detection baffle 5 rotates, it can contact pressure sensor 7 and apply pressure to pressure sensor 7. Pressure sensor 7 is connected to controller 8. Controller 8 adopts existing conventional PLC controller. Controller 8 is connected to conveyor belt 1. Pressure sensor 7 can send signals to controller 8. Controller 8 can control conveyor belt 1 to stop running.

[0014] The hopper 2 is equipped with multiple parallel and horizontally arranged buffer rods 9. When the material is fed into the hopper 2 from the top, the buffer rods 9 can buffer the material and slow down the falling speed, preventing the material from accumulating rapidly at the bottom of the feed cylinder 3. The side wall of the hopper 2 is also fixed with a vibration motor 10, which can discharge all the material in the hopper 2 to prevent residue.

[0015] The method of using this utility model is as follows: During material transportation, the material is first added to the hopper 2, and then falls through the feed cylinder 3 onto the conveyor belt 1 to be transported to the corresponding position. During the transportation process, the material passes through the discharge port 4. When the material is pushed at the bottom of the feed cylinder 3, the height of the material on the conveyor belt 1 increases. When it moves to the discharge port 4, it comes into contact with the detection baffle 5, causing the detection baffle 5 to rotate. When a large amount of material accumulates at the bottom of the feed cylinder 3, the detection baffle 5 can come into contact with the pressure sensor 7 and apply pressure to the pressure sensor 7. When the pressure sensor 7 detects that the pressure has reached the set value, it can send a signal to the controller 8. The controller 8 controls the conveyor belt 1 to stop running so that the operator can handle the situation in time and prevent damage to the equipment.
