At the same time, during the detection process, the detection element is easily affected by the impact of materials in the chute, resulting in equipment damage or inaccurate detection data.

[0004] Therefore, a mine chute material level detection device is proposed to address the above problems. Utility Model Content

[0022] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the scope of protection of the present utility model.

[0023] Please see Figures 1-5 As shown, a mine chute material level detection device includes a main body 1. A protective detection component 2 is provided on one side of the main body 1. The protective detection component 2 includes a detection element 3 for detection and a protective element 4 for protection. The detection element 3 includes a connecting plate 21 located at the bottom of the main body 1. Several cameras 23 are fixedly installed at the bottom of the connecting plate 21. A connecting rod 22 is fixedly installed at the bottom of the connecting plate 21. A protective chamber 24 is fixedly installed at the bottom end of the connecting rod 22. A remote control main board 25 is fixedly installed in the inner cavity of the protective chamber 24. An LED light strip 26 is fixedly installed on the bottom outer surface of the protective chamber 24. The remote control main board 25 is electrically connected to the cameras 23 and an ultrasonic distance sensor 27. The ultrasonic distance sensor 27 is fixedly installed in the inner cavity of the protective chamber 24. The protective chamber 24 has an installation groove, through which a battery 30 can be detachably installed.

[0024] During operation, the chute is filled with stone materials, which occupy the overall depth of the chute. When the detection component 3 is lowered for distance measurement, it will be blocked by the upper layer of material. Therefore, an ultrasonic distance sensor 27 is used. The ultrasonic distance sensor 27 relies on the camera 23 to determine whether the ultrasonic distance sensor 27 has reached the upper side of the stone material. Then, the ultrasonic distance sensor 27 transmits and receives ultrasonic waves from the upper layer of the stone material to the lower layer of the stone material, so as to accurately determine the depth of the material filling in the chute.

[0025] Furthermore, the main body 1 includes a torque motor 11 with a self-locking function, a winch 12 is fixedly installed at the output end of the torque motor 11, a fixed seat 13 is installed through and movably at both ends of the winch 12, and a connecting plate 21 is fixedly installed at the output end of the winch 12.

[0026] During operation, the torque motor 11 with self-locking function drives the winch 12 to move the protective detection component 2 up and down, adapting to the detection needs of chutes at different depths. The self-locking function of the torque motor 11 ensures that the detection component stays stably at the target position, avoiding positional deviation caused by material impact or gravity.

[0027] Furthermore, the protective component 4 includes a first fixed sleeve 28, and three first movable arms 29 are hinged to the outer surface of the first fixed sleeve 28. A protective plate 31 is hinged to the other side of each of the three first movable arms 29. The first fixed sleeve 28 is sleeved and fixedly installed on the outer surface of the connecting rod 22.

[0028] During operation, the first fixed sleeve 28 is hinged to the three first movable arms 29, providing basic support for the protective plate 31. During the lowering process, it initially unfolds to form a cone-shaped protective area, buffering the impact of larger particles in advance.

[0029] Furthermore, the protective component 4 also includes a second fixed sleeve 33, the outer surface of which is hinged with three second movable arms 32, the other end of each of the three second movable arms 32 is hinged with a protective plate 31, and the second fixed sleeve 33 is sleeved and fixedly installed on the outer surface of the connecting rod 22.

[0030] During operation, the addition of the second fixed sleeve 33 and the second movable arm 32 forms a double-layer hinged support structure, which keeps the protective plate 31 stably in the unfolded state and resists the continuous impact of materials.

[0031] Furthermore, the protective component 4 also includes a movable sleeve 35, the outer surface of which is hinged with three reduction arms 34, the other ends of which are all hinged to the middle of the second movable arm 32, and the movable sleeve 35 is fitted and movably installed on the outer surface of the connecting rod 22.

[0032] During operation, the hinged design of the movable sleeve 35 and the return arm 34 enables the first movable arm 29 and the second movable arm 32 to move synchronously up and down. When lowering, the movable sleeve 35 moves down and pulls the second movable arm 32 through the return arm 34 to ensure that the protective plate 31 is evenly unfolded. When impacted, the movable sleeve 35 moves up and causes the protective plate 31 to temporarily retract inward to buffer the impact energy.

[0033] Furthermore, a return spring 36 is fixedly installed on the top of the movable sleeve 35, and a first fixed sleeve 28 is fixedly installed on the top of the return spring 36.

[0034] During operation, the reset spring 36 connects the first fixed sleeve 28 and the movable sleeve 35, providing elastic buffering force: when impacted, the compressed spring absorbs energy to avoid rigid collisions damaging components. After impact, the spring resets, pushing the movable sleeve 35 downward, so that the protective plate 31 automatically returns to its initial protective state without manual intervention, thus enhancing the equipment's autonomous protection capability.

[0035] Working principle: During detection, the camera 23 at the bottom of the connecting plate 21, illuminated by the LED light strip 26, determines whether the ultrasonic distance sensor 27 has reached the upper side of the stone material. The remote control motherboard 25 controls the ultrasonic distance sensor 27 to transmit and receive ultrasonic waves from the upper layer of the material to the lower layer, thereby accurately calculating the material filling depth and performing data processing and transmission. In terms of protection, the first fixed sleeve 28 and the second fixed sleeve 33 are linked by the first movable arm 29, the second movable arm 32 and the return arm 34 to link the movable sleeve 35, so that the protective plate 31 is evenly unfolded to form a double-layer conical protective area when it is lowered. When impacted by the material, the movable sleeve 35 moves upward and drives the protective plate 31 to temporarily retract inward. The return spring 36 is used to compress and absorb the energy. After the impact, the spring returns and pushes the movable sleeve 35 downward so that the protective plate 31 returns to the initial protective state.

[0036] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of this utility model. Various changes and modifications can be made to this utility model without departing from its spirit and scope, and all such changes and modifications fall within the scope of the claimed utility model.
