Description

Technical Field

[0001] This utility model relates to the field of belt conveyor technology, and in particular to a belt conveyor blockage detection device. Background Technology

[0002] A belt conveyor is short for belt conveyor, and it comes in stationary and mobile types. It is a simple and efficient machine that uses a flexible conveyor belt as the material-carrying and traction component. An endless conveyor belt wraps around a drive drum and a redirecting drum. The upper and lower branches between the two drums are each supported by several idlers. Material is placed on the upper branch, and the friction between the drive drum and the belt pulls the conveyor belt and the material along.

[0003] Traditional material blockage detection devices installed at the head of belt conveyors may malfunction or trigger false alarms due to improper installation location or different material stacking angles. Utility Model Content

[0004] The purpose of this invention is to address the aforementioned problems and shortcomings by proposing a belt conveyor blockage detection device: when material comes into contact with a pressure sensor at any position on the detection rod, the controller receives the signal, triggers an alarm, and simultaneously stops the conveyor motor. The pressure sensors evenly installed on the detection rod increase the detection range and reduce the probability of false triggering.

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

[0006] A belt conveyor blockage detection device includes two support plates, with conveyor rollers rotatably connected to both ends of the two support plates. A conveyor belt is installed on the outer wall of the conveyor rollers. A detection component is installed at the center of the top outer wall of the support plate, and an auxiliary component is provided on the bottom outer wall of one end of the support plate. The detection component includes a mounting frame installed on the top outer wall of the support plate, an electric push rod I embedded in the center of the mounting frame, a detection rod installed on the bottom outer wall of the electric push rod I, and pressure sensors installed at equal distances on one side outer wall of the detection rod. The auxiliary component includes two sets of mounting frames, an electric push rod II installed on the bottom inner wall of the mounting frame, and a bearing seat installed on the top outer wall of the electric push rod II.

[0007] Preferably, a controller is mounted on one outer wall of the mounting frame, and the signal input terminal of the pressure sensor is connected to the signal input terminal of the controller;

[0008] When material comes into contact with the pressure sensor at any position on the detection rod, the controller receives the signal, issues an alarm, and stops the conveyor motor. The pressure sensors, evenly installed on the detection rod, increase the detection range and reduce the chance of false triggering.

[0009] Preferably, a cleaning roller is installed between the bearing seats, and the outer wall of the cleaning roller is provided with metal wires distributed at equal intervals. The two outer walls of the bearing seats are slidably connected to the inner outer wall of the mounting frame.

[0010] Preferably, a drive motor is mounted on one side outer wall of one of the bearing housings, and the output shaft of the drive motor is connected to one end of the cleaning roller.

[0011] Preferably, the bottom of the cleaning roller is provided with a feeding sloping plate, and one end of the metal wire is slidably connected to the outer wall of the conveyor belt;

[0012] The drive motor rotates the cleaning roller on the bearing housing. The electric push rod 2 starts and drives the cleaning roller to rise and contact the conveyor belt, sweeping off the material adhering to the conveyor belt, preventing the conveyor belt from carrying the material back, facilitating material discharge and preventing material blockage at the discharge end.

[0013] Preferably, a conveying motor is installed at one end of the support plate on the conveying roller, and the output shaft of the conveying motor is connected to one end of the conveying roller.

[0014] Preferably, the conveying motor, electric push rod one, electric push rod two, and drive motor are connected to the controller via wires, and the controller is connected to the power supply via wires.

[0015] The beneficial effects of this utility model are as follows:

[0016] 1. When the material comes into contact with the pressure sensor at any position on the detection rod, the controller will receive the signal, sound an alarm, and stop the conveyor motor. The pressure sensors are evenly installed on the detection rod to increase the detection range and reduce the chance of false triggering.

[0017] 2. The drive motor drives the cleaning roller to rotate on the bearing seat. The electric push rod 2 starts and drives the cleaning roller to rise and contact the conveyor belt, sweeping off the material adhering to the conveyor belt, preventing the conveyor belt from carrying the material back, facilitating material feeding and preventing material blockage at the feeding end.

Detailed Implementation

[0023] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0024] Example 1:

[0025] Reference Figure 1 and Figure 4 A belt conveyor blockage detection device includes two support plates 1, with conveyor rollers rotatably connected at both ends between the two support plates 1, and a conveyor belt 14 installed on the outer wall of the conveyor rollers. A detection component 2 is installed at the center of the top outer wall of the support plate 1, and an auxiliary component 3 is provided on the bottom outer wall of one end of the support plate 1, which facilitates the adjustment of the detection position according to the height of the conveyed material and reduces the probability of accidental triggering.

[0026] A conveyor motor 15 is mounted on one end of the support plate 1 and the output shaft of the conveyor motor 15 is connected to one end of the conveyor roller.

[0027] The detection component 2 includes a mounting bracket 4 installed on the top outer wall of the support plate 1, an electric push rod 5 embedded in the center of the mounting bracket 4, a detection rod 6 installed on the bottom outer wall of the electric push rod 5, and pressure sensors 7 installed at equal intervals on one side outer wall of the detection rod 6. When the material comes into contact with the pressure sensor 7 at any position on the detection rod 6, the controller 16 receives the signal and alarms while stopping the conveying motor 15. The pressure sensors 7 installed evenly on the detection rod 6 increase the detection range and reduce the probability of false triggering.

[0028] The conveyor motor 15, electric push rod 1 5, electric push rod 2 9 and drive motor 13 are connected to controller 16 through wires, and controller 16 is connected to power supply through wires. When electric push rod 1 5 is started, it drives the detection rod 6 to move on the mounting frame 4, and adjusts the distance between the detection rod 6 and the conveyor belt 14.

[0029] Example 2:

[0030] Reference Figure 2-4The auxiliary component 3 includes two sets of mounting frames 8, an electric push rod 2 9 mounted on the inner wall of the bottom of the mounting frame 8, and a bearing seat 10 mounted on the outer wall of the top of the electric push rod 2 9. When the drive motor 13 is started, it drives the cleaning roller 11 to rotate on the bearing seat 10. When the electric push rod 2 9 is started, it drives the cleaning roller 11 to rise. The metal wire 12 contacts the conveyor belt 14 and sweeps off the material adhering to the conveyor belt 14, preventing the conveyor belt 14 from bringing the adhering material back, which facilitates material feeding and prevents material blockage at the feeding end.

[0031] A controller 16 is installed on one outer wall of the mounting frame 8, and the signal input terminal of the pressure sensor 7 is connected to the signal input terminal of the controller 16.

[0032] A cleaning roller 11 is installed between the bearing seats 10, and the outer wall of the cleaning roller 11 is provided with metal wires 12 distributed at equal intervals. The outer walls of both sides of the bearing seats 10 are slidably connected to the inner outer wall of the mounting frame 8.

[0033] A drive motor 13 is mounted on one outer wall of a bearing housing 10, and the output shaft of the drive motor 13 is connected to one end of the cleaning roller 11.

[0034] The bottom of the cleaning roller 11 is provided with a feeding sloping plate 17, and one end of the metal wire 12 is slidably connected to the outer wall of the conveyor belt 14. The feeding sloping plate 17 guides the swept material.

[0035] Working principle: In use, the detection component 2 and auxiliary component 3 are respectively installed on the support plate 1 and one end of the conveyor belt 14. The electric push rod 5 is activated to move the detection rod 6 on the mounting frame 4, adjusting the distance between the detection rod 6 and the conveyor belt 14 to facilitate adjustment of the detection position according to the height of the conveyed material, reducing the probability of false triggering. The conveyor motor 15 conveys the material through the conveyor rollers and the conveyor belt 14. The material passes under the detection rod 6. If the material on the conveyor belt 14 is higher than or level with the detection rod 6, the material contacts the pressure sensor 7 at any position on the detection rod 6, triggering the control. After receiving the signal, the controller 16 alarms and stops the conveyor motor 15. The pressure sensors 7, which are evenly installed on the detection rod 6, increase the detection range and reduce the probability of false triggering. The conveyor belt 14 discharges material at one end. Since the blockage is partly related to the moisture content of the material, the drive motor 13 is started to drive the cleaning roller 11 to rotate on the bearing seat 10. The electric push rod 2 9 is started to drive the cleaning roller 11 to rise. The metal wire 12 contacts the conveyor belt 14 and sweeps off the material adhering to the conveyor belt 14 to prevent the conveyor belt 14 from carrying the adhering material back, which facilitates material discharge and prevents blockage at the discharge end.
