Description
Technical Field
[0001] This utility model relates to the field of skip technology, specifically to a skip unloading port anti-spillage adjustment structure. Background Technology
[0002] Skip is a common type of mining transport equipment, typically used to lift ore materials from underground mines to the surface. It is one of the key pieces of equipment in a mine's vertical shaft transport system. Skip is characterized by its simple structure, rapid loading and unloading, and high transport efficiency, and is widely used in mining production. As the core transport tool of the vertical shaft system, the design and operating efficiency of the skip directly affect the overall production capacity and economic benefits of the mine.
[0003] A mining vertical shaft skip is a type of skip specifically designed for vertical shaft transportation. Its working principle involves vertically lifting materials from underground to the surface using the traction of a hoist. The discharge port of a vertical shaft skip is typically designed at the bottom of the skip, utilizing the material's own weight for unloading. Currently, mining vertical shaft skips mainly employ the following structures for closing and opening the discharge port: gravity cover type, where the cover is closed by its own weight and opened by external force during unloading; spring-locking type, where a spring mechanism locks the discharge port and unlocks it during unloading; hydraulic or electric control type, using hydraulic cylinders or motors to drive the opening and closing of the discharge port, improving automation; and sliding door design, using a sliding rail device to control the movement of the discharge door. These closing and opening methods effectively prevent material spillage during transportation, but some problems still exist during the unloading stage.
[0004] In actual operation, the design of existing vertical shaft skip discharge ports is prone to spillage during unloading. This is because the instantaneous full opening of the discharge port causes material to flow at high speed, making it difficult to effectively control the flow direction. Some material may splash or overflow due to inertia, accumulating around the shaft opening. This spillage increases the workload of shaft opening cleaning, reduces production efficiency, and in severe cases, may even affect the safety of shaft opening equipment and personnel. Therefore, to address the problem of easy spillage during unloading of existing vertical shaft skip discharge ports, there is an urgent need for an improved structure to enhance the airtightness and flow direction control of the unloading process, reducing cleaning workload while ensuring the efficiency and safety of mining operations. In view of this, we propose a spillage prevention and adjustment structure for skip discharge ports. Utility Model Content
[0005] The purpose of this invention is to provide a spill-proof adjustment structure for the skip discharge port to solve the problems mentioned in the background art.
[0006] To achieve the above objectives, this utility model provides the following technical solution:
[0007] The skip discharge port anti-spillage adjustment structure includes an I-shaped base. The left and right sides of the top of the I-shaped base are provided with fixed vertical plates for fixing the storage box and forming the frame support structure of the device.

[0009] The rear end of the guide tube is fitted with a sleeve, and the rear end of the sleeve is a closed structure. A discharge port is opened at the bottom of the outer wall of the sleeve at the rear end, which is the outlet for the material to be discharged from the device. Two first fixed protrusions are provided on the outer wall of the guide tube near the front end, and electric telescopic rods are provided on the rear side of the two first fixed protrusions. The electric telescopic rods are connected to an external power supply and controller.

[0010] Preferably, a connecting top plate is provided between the two fixed vertical plates and near the top to enhance the rigidity and stability between the two fixed vertical plates and prevent deformation. The top of the connecting top plate is provided with two lifting rings arranged symmetrically on the left and right for hoisting and moving the device, which facilitates moving it up and down in the mine.
[0011] Preferably, the left and right sides of the storage box are respectively fixedly connected to the opposite sides of the two fixed vertical plates by bolts, so that the position of the storage box and the two fixed vertical plates is relatively fixed.
[0012] Preferably, a protective cover is provided on the front side of the mounting end plate, the motor is located inside the protective cover, and heat dissipation holes are provided on the outer wall of the protective cover. The protective cover is used to protect the motor from the influence of the external environment and prevent materials from falling and hitting the motor. At the same time, the heat dissipation holes ensure the normal heat dissipation of the motor.
[0013] Preferably, when the movable rod of the electric telescopic rod is fully retracted, the rear side of the inner wall of the sleeve is in contact with the rear side of the guide tube, ensuring that the material is not discharged during the upward movement of the skip.
[0014] Preferably, a second fixing protrusion is provided at the bottom of the outer wall of the guide tube and near the front end. A circular fixing tube is provided on the rear side of the second fixing protrusion to provide sliding positioning support for the positioning rod and ensure the stability of the sleeve when it moves.
[0015] Preferably, a second connecting protrusion is provided at the bottom of the outer wall of the sleeve and near the front end. A positioning rod is provided on the front side of the second connecting protrusion. The positioning rod is slidably connected inside the circular fixed tube to improve the movement stability of the sleeve and ensure its return accuracy.
[0016] Compared with the prior art, the beneficial effects of this utility model are:
[0017] 1. The anti-spillage adjustment structure of the skip discharge port, by setting an anti-spillage component at the bottom of the discharge pipe, including a guide pipe, a sleeve and a discharge port, and cooperating with the auger for material conveying and flow regulation, effectively controls the flow direction and speed of the material during the discharge process, and avoids the phenomenon of material scattering around the wellhead due to high-speed impact or inertial splashing. After the structure is optimized, it not only improves the airtightness of the discharge process, but also avoids the waste of resources and material accumulation.
[0018] 2. The anti-spillage adjustment structure of the skip discharge port, by improving the anti-spillage components, uses an electric telescopic rod to adjust the position of the sleeve and the opening and closing degree of the discharge port. While ensuring the smooth output of materials, it greatly reduces the possibility of leakage and reduces the workload of cleaning the wellhead from the root.
[0019] 3. The anti-spillage adjustment structure of the skip discharge port is provided with a first fixed protrusion and a second fixed protrusion on the outer wall of the guide pipe, which are used to fix the electric telescopic rod and the circular fixed pipe respectively. The sleeve is slidably connected by the positioning rod. While ensuring the flexible operation of the anti-spillage component, the stability of the overall structure is increased, which effectively avoids shaking or misalignment during the unloading process and ensures the safety and reliability of operation.
[0020] 4. The anti-spillage adjustment structure of the skip discharge port ensures that when the movable rod of the electric telescopic rod is fully retracted, the rear side of the inner wall of the sleeve fits against the rear side of the guide pipe, forming a closed state. This ensures that no material will be discharged from the skip when it is being lifted or not in operation. This design reduces the risk of accidental material falling and further improves the safety of the device. Attached Figure Description

The motor 82 is turned on to drive the auger 84 to rotate, uniformly conveying the material from the guide pipe 80 to the discharge port 850 of the sleeve 85. After unloading is completed, the controller turns off the motor 82 and the electric telescopic rod 86, causing the electric telescopic rod 86 to retract, so that the rear end of the sleeve 85 fits against the rear end of the guide pipe 80, completely sealing the discharge port 850 and preventing residual material from spilling out. Through the above operations, the efficient and safe operation of the skip discharge port anti-spillage adjustment structure can be achieved.
