[0020] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0021] Example 1: Please refer to Figure 1-5The utility model provides an embodiment: a pneumatic belt transfer machine, which is driven by a pneumatic motor 5. There are factors such as moisture and dust in the underground environment, which can easily cause electrical equipment failure. Since the pneumatic motor 5 has no electrical components, the risk of being affected by factors such as moisture and dust is reduced, and the reliability of the equipment is improved. The pneumatic motor 5 does not need to use electricity or fuel. It is driven by wind power, so no emissions are generated during use. It is an environmentally friendly and energy-saving driving method. Since there are no complex electrical components, it is not easily affected by power fluctuations, circuit failures and other problems. Therefore, it is more reliable than electric motors in underground coal mines. It includes a belt bracket 1, a moving wheel 2, a locking device 303, and an adjusting device 306. The belt bracket 1 is a welded frame. The belt bracket 1 is used to support and fix the belt and related components. The left and right sides of the belt bracket 1 are respectively connected to hydraulic rods. The hydraulic The rod is widely applicable to conveyor lines or material stacking heights of different heights, which increases its applicability and flexibility. The hydraulic rod is located at the front and rear ends of the left and right sides of the belt support 1. The bottom end of the hydraulic rod is connected to a moving wheel 2. The left and right hydraulic rods are connected by reinforcing ribs. The moving wheel 2 is connected to the bottom end of the hydraulic rod, so that the conveyor can move. The reinforcing ribs form an integral linkage for left and right movement, which is convenient for movement. A number of belt rollers 302 are evenly distributed on the top of the belt support 1. The belt rollers 302 are evenly distributed on the top of the belt support 1 to support and guide the operation of the belt. The right end of the belt roller 302 is evenly distributed with fixed blocks, which are fixedly connected to the belt support 1. The fixed block is hinged with a coal collecting plate 3301 A locking device 303 is connected to the coal collecting plate 3301. A roller 301 is hinged on the front side end of the belt bracket 1 for driving the belt transportation. A belt is arranged on the roller 301. The roller 301 is located at the left side end of the belt bracket 1 for installing the belt and is connected to the output end of the pneumatic motor 5 to transmit power to the belt. The roller 301 is connected to the output end of the pneumatic motor 5. An adjusting frame 304 is welded to the rear side end of the belt bracket 1. An adjusting device 306 is connected to the adjusting frame 304. A flat roller 305 is slidably matched between the two adjusting devices 306. A coal collecting hopper 6 is welded to the bottom end of the adjusting frame 304 for collecting coal. The flat roller 305 cooperates with the adjusting device 306 to help adjust the belt. The tension also includes a fall chain 4, which is installed at the two belt joints to tighten the belt joints to ensure the continuity and stability of the belt. The belt joints connect two sections of belts, but because the belts will relax and stretch to a certain extent during use, this causes the belts at the joints to loosen or even detach. The function of the fall chain 4 is to tighten the belts at the joints through its own tension to ensure that the belts at the joints can be closely connected, thereby avoiding the occurrence of belt breakage or jamming. The fall chain 4 is installed at the two belt joints to tighten the belt joints. A coupling 7 is connected between the output end of the pneumatic motor 5 and the drum 301. The coupling 7 adopts a flange connection structure, in which the front end is connected to the shaft sleeve and the other end is connected to the gear sleeve.The design of coupling 7 simplifies the installation of coupling 7. The installer only needs to connect the sleeve and gear sleeve to the corresponding shaft respectively, without having to perform complicated alignment operations on the same shaft. The design of coupling 7 helps to reduce the vibration and impact caused by misalignment of the shaft or uneven load in the transmission system, which helps to extend the life of the equipment and bearings and improve the stability of the overall system.
