Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of coal mine loading devices, in particular to an environmentally friendly and energy-saving loading device for coal mine machinery. BACKGROUND

[0002] The coal mine loading device is a device for transporting mined coal. It generally moves along a track laid in the coal mine, and drives the coal mine loading device to move from the mining area to the coal transportation area, effectively improving the efficiency of coal mining and transportation.

[0003] The existing Chinese patent application No. CN114607455A discloses a loading device for underground coal transportation, which includes a vehicle frame, a transportation frame, and a control console. The control console is installed on one side of the transportation frame. The loading device also includes a digging mechanism installed on the upper part of the transportation frame, a crushing mechanism installed on the opposite front part of the transportation frame, and a transportation mechanism installed at the bottom of the transportation frame. The digging mechanism is used to dig coal onto the transportation frame, the crushing mechanism is used to crush the coal transported onto the transportation frame, and the transportation mechanism is used to transport the crushed coal. This invention can solve the problem of needing to combine multiple machines to process collected coal when collecting underground coal, which is not conducive to improving coal collection efficiency.

[0004] However, the loading device has the following defects when used in detail: 1. When the existing loading device is used for coal transportation, the mined coal needs to be moved into the loading device through a conveying belt. In actual loading of coal, the mined coal can be divided into coal and coal residue (including coal dust) according to its grade and form. Coal has a high value and can be processed into high-value honeycomb coal through subsequent simple processing, while coal residue (including coal dust) has a low value and needs to be processed through complex processes such as re-calcination or sold as inferior products. Traditional loading devices generally transport different types of coal uniformly, making it difficult to separate coal according to type, resulting in the need for additional classification of coal when transported to the coal transportation area, which is inefficient. 2. When the existing loading device unloads the loaded coal, it needs to open the discharge port of the loading device and then tilt the loading device to remove the coal inside. However, during actual unloading of coal, due to the high humidity inside the mined coal, some of the loaded coal tends to stick to the inside of the loading device, making it difficult to unload all at once. Therefore, workers need to manually shovel out the stuck coal, affecting the efficiency of coal loading and unloading. SUMMARY

[0040] In the coal mine machinery environment-friendly and energy-saving loading device, when the unloaded coal residue is unloaded, the L-shaped support 5013 moves downward, pushes the lower toothed rod 5031 to move downward, and enables the lower gear 5032 meshed and connected on the side of the lower toothed rod 5031 to rotate. When the lower gear 5032 rotates, the lower reciprocating wire rod 5033 connected on the side of the lower gear 5032 rotates, so that the lower reciprocating wire rod 5033 on the outside can move through the lower sliding seat 5034 connected by the ball, and drive the bottom closing plate 402 to move outward, open the discharge port position of the loading inner frame 20.

[0041] In the present application, the directions of the internal spiral raceways of the two lower reciprocating wire rods 5033 are opposite, and the lock structure is installed at the ports of the two lower reciprocating wire rods 5033.

[0042] Example two

[0043] On the basis of the above-mentioned examples, it is found that when the oblique unloading assembly 30 drives the loading inner frame 20 to move, the loading inner frame 20 is in an inclined state and unloads the coal mine in the loading inner frame 20, and then the loading inner frame 20 needs to be returned to the initial position, and the loading inner frame 20 is supported by the bearing plate 101, so as to reduce the pressure on the oblique unloading assembly 30. However, the loading inner frame 20 is returned to the initial position by the connecting rod structure, and the loading inner frame 20 is returned to the initial position in an arc-shaped manner. At this time, in the process of returning the loading inner frame 20, the arc-shaped extrusion force is easy to cause inconsistent extrusion on each part of the buffer part (air bag or rubber, etc.) on the top of the bearing plate 101, and is easy to wear or even damage the buffer part of the bearing plate 101.

[0044] Therefore, with reference to Figure 13 A guide groove 60 is formed on the left and right sides of the inner wall of the loading outer frame 10, a hydraulic system 601 is installed on the inner bottom of the guide groove 60 through screws, a supporting spring 602 located in the guide groove 60 is installed on the outside of the hydraulic system 601, the top of the supporting spring 602 is installed on the bottom of the bearing plate 101 through a damping block, the bearing plate 101 and the guide groove 60 are in sliding connection, and the output end of the hydraulic system 601 abuts against the bottom of the bearing plate 101.

[0045] In the coal mine machinery environment-friendly and energy-saving loading device, through the movable bearing plate 101, when the arc-shaped moving loading inner frame 20 is in contact with the bearing plate 101, the bearing plate 101 is driven to move towards each other by extrusion, space is left for the movement of the bearing plate 101. And after the bearing plate 101 moves to the initial position (horizontal direction), the supporting spring 602 will move downward due to the weight of the coal mine, so that the hydraulic system 601 and the bearing plate 101 will be in contact. At this time, the loading inner frame 20 for loading coal mine can be supported by the hydraulic system 601, reducing the probability of damage to the inclined unloading assembly 30 and the bearing plate 101 buffer part due to the overloading of the coal mine. At the same time, in the process of driving the loading inner frame 20 to swing, the supporting spring 602 can cooperate with the hydraulic system 601 to buffer the deflection force during swinging, improving safety.

[0046] Therefore, any person skilled in the art within the technical scope disclosed by the present application, according to the technical scheme and the inventive concept of the present application, can make equivalent replacement or change, which should be covered by the protection scope of the present application.
