Furthermore, fixed vertical coal bunkers are difficult to locate, have strict geological requirements, and are subject to significant limitations, resulting in substantial engineering investment. They also cannot be stored, transported, and weighed near the tunnel face to reduce site selection and construction costs, leaving room for further improvement in economic efficiency.

[0003] Now, a novel horizontal quantitative loading device for coal bunkers with a detection mechanism is proposed to solve the above problems. Utility Model Content

Multiple sets of support rollers are movably connected between the front and rear ends of the top of the main frame.

[0007] As a further technical solution of this utility model, the top end of the speed measuring roller is in contact with the belt, and the belt can drive the speed measuring roller to rotate.

[0008] As a further technical solution of this utility model, the front end of the speed measuring roller is connected to the input end of the speed sensor, and the top end of the speed sensor is fixedly connected to the main frame.

The pulling screw passes through the left side of the square frame. The internal thread of the positioning nut matches the external thread of the pulling screw.

[0012] Compared with the prior art, the beneficial effects of this utility model are: the horizontal quantitative loading device for coal bunkers with a detection mechanism not only realizes the functions of convenient nearby storage and weighing, but also the functions of convenient conveying and discharging, and the functions of convenient adjustment of belt tension; Equipped with a speed measuring roller, speed sensor, sensor bracket, load cell, bearing housing, weighing force roller, idler roller, and belt, the main frame is erected near the tunnel face during operation. The excavated bulk material is directly stored in the horizontal bin. The belt supports the bulk material at the bottom of the horizontal bin, and multiple sets of idler rollers provide support to the belt. The drive motor unit drives the head drum to rotate at a constant speed, which in turn drives the belt to rotate at a constant speed, conveying the bulk material from the tail end of the horizontal bin to the head end, preventing excessive accumulation at the tail. As the belt carries the bulk material past the weighing force roller... The belt conveyor above presses down on the bearing seat under the force of the weighing roller, and the weighing sensor can measure the weight of the bulk material in the upper section in real time. The movement of the belt also drives the rotation of the speed measuring roller. The speed sensor calculates the belt speed based on the number of rotations of the speed measuring roller. The speed and weight data are combined, and the continuous output weight can be calculated by the algorithm. The horizontal silo itself can store a large amount of coal, and its installation and layout are simpler and the cost is lower than that of the vertical storage silo. It can also complete the initial storage work at the tunneling face, realizing the function of convenient local storage and weighing. With the addition of a belt, curved guide plates, and a discharge port, the two sets of curved guide plates guide the material in the horizontal bin to the belt, preventing it from overflowing from the bottom due to pressure. As the drive motor unit drives the head roller to rotate continuously, the material in the horizontal bin is continuously transported by the belt to the discharge port and discharged, facilitating its transfer to the subsequent conveying system and realizing the function of easy conveying and discharging. The belt is equipped with a square frame, slide rail, sliding block, tension roller, traction screw, and positioning nut. During use, the belt is supported by the head roller, belt, redirecting roller, tension roller, and tail roller. Its tension can be adjusted by adjusting the position of the tension roller. By rotating the positioning nut, the position of the traction screw can be adjusted. The traction screw drives the sliding block to slide along the slide rail inside the square frame, thus changing the tension roller and the belt tension, achieving the function of easily adjusting the belt tension.

The tops of the weighing force roller 9 and the idler roller 10 are flush with each other. The tops of the weighing force roller 9 and the idler roller 10 are in contact with the belt 11, which can drive the weighing force roller 9 and the idler roller 10 to rotate, which facilitates nearby storage and weighing. Specifically, such as Figure 1 , Figure 2 , Figure 4 and Figure 5 As shown, as the belt 11 carries the bulk material past the weighing roller 9, the weighing roller 9 presses down on the bearing seat 8, and the weighing sensor 7 can measure the weight of the bulk material at the upper section in real time.

[0019] Working Principle: In use, the main frame 1 is first erected in the roadway near the excavation face. The excavated bulk material is directly stored in the horizontal bin 2. The belt 11 supports the bulk material at the bottom of the horizontal bin 2, and multiple sets of idlers 10 provide support for the belt 11. The drive motor unit 23 drives the head roller 3 to rotate at a constant speed, which in turn drives the belt 11 to rotate at a constant speed, conveying the bulk material from the tail of the horizontal bin 2 to the head, preventing excessive accumulation at the tail. As the belt 11 carries the bulk material past the belt above the weighing roller 9... 11. The weighing roller 9 presses down on the bearing seat 8, and the weighing sensor 7 can measure the weight of the bulk material at the upper section in real time. The movement of the belt 11 drives the rotation of the speed measuring roller 4. The speed sensor 5 measures the speed of the belt 11 based on the number of revolutions of the speed measuring roller 4. The speed and weight data are combined, and the continuous output weight can be calculated by the algorithm. The horizontal silo 2 itself can store a large amount of coal, and its installation and layout are simpler and less expensive than that of a vertical storage silo. It can also complete the initial storage work at the tunneling face. Two sets of arc-shaped guide plates 12 can guide the material in the horizontal silo 2 to the belt 11 to prevent it from overflowing from the bottom due to pressure. As the drive motor unit 23 drives the head roller 3 to operate continuously, the material in the horizontal silo 2 is continuously transported by the belt 11 to the discharge port 22 and discharged, which is convenient for connecting to the subsequent conveying system for external transfer. The belt 11 is supported by the head roller 3, belt 11, redirecting roller 13, tension roller 17, and tail roller 21. Its tension can be adjusted by adjusting the position of tension roller 17. By rotating the positioning nut 19, the position of the traction screw 18 can be adjusted. The traction screw 18 drives the sliding block 16 to slide along the slide rail 15 in the square frame 14, thus changing the tension roller 17 and the tension of belt 11.
