Description

Technical Field

[0001] The utility model relates to the field of self-moving tails, in particular to a self-moving tail for a belt conveyor. Background Art

[0002] The self-moving tail is a device used in coal mining, mainly used in coal mining working faces. It can move automatically during the mining process and adjust its position as the mining progress changes. Its main advantages are improved work efficiency, reduced demand for manual operation, and the ability to adapt to different mining conditions. The self-moving tail usually includes an electric drive system, a moving mechanism, and a control system, which can achieve smooth and automatic movement and adjustment to ensure the continuity and safety of coal mine operations.

[0003] After searching, the Chinese patent "A self-moving tail for a belt conveyor" authorization announcement number is "CN215158116U". The utility model relates to a self-moving tail for a belt conveyor, including a tail frame, a hydraulic support device, a hydraulic pushing device, a base, a guide rail, casters and a connecting piece. The bottom end of the guide rail is fixedly connected to the top end of the base, the top end of the connecting piece is fixedly connected to the bottom end of the hydraulic support device, the top end of the hydraulic support device is fixedly connected to the bottom end of the tail frame, one end of the hydraulic pushing device is fixedly connected to the bottom end of the tail frame through a fixed block, and the other end is fixedly connected to the top end of the guide rail. A fixed plate is fixedly provided at the top of the tail frame, a fixed rod and a sliding rod are provided at the top of the fixed plate, a guardrail is hinged between the fixed rod and the sliding rod, a screw motor is fixedly provided at the top of the fixed plate, a screw motor is fixedly provided at the output end of the screw motor, the other end of the screw is hinged to a limiting block, the bottom end of the limiting block is fixedly connected to the top end of the fixed plate, a screw slider is slidably provided on the screw, and the top end of the screw slider is fixedly connected to the bottom end of the sliding rod.

[0004] The above-mentioned guardrail intercepts coal blocks during the process of transferring coal blocks to prevent coal blocks from splashing and ensure the safety of workers. However, the surface of the guardrail is hollowed out, and smaller particles will still splash out through the gaps in the guardrail, reducing the protective effect.

[0023] When implementing: Figure 1-4 As shown, a self-moving tail for a belt conveyor comprises: a conveyor body 1, pulleys 2 are arranged on both sides of the bottom of the conveyor body 1, a conveyor belt body 3 is arranged in the inner cavity of the conveyor body 1, limit plates 4 are fixedly connected to both sides of the top of the conveyor body 1, a self-moving tail body 5 is arranged in the inner cavity of the conveyor body 1, and a mounting shell 6 is fixedly connected to the bottom of the self-moving tail body 5; a protective mechanism 7, the protective mechanism 7 is arranged at the bottom of the mounting shell 6; wherein the protective mechanism 7 comprises a support plate 705 arranged in the inner cavity of the mounting shell 6, two positioning shells 708 are symmetrically fixedly connected to the top of the support plate 705, and pull rods 709 are inserted on both sides of the positioning shell 708, one end of the pull rod 709 passes through the inner cavity of the positioning shell 708 and is fixedly connected to an extrusion block 710, one side of the extrusion block 710 is fixedly connected to a tension spring 711, and one end of the tension spring 711 is fixedly connected to the inner cavity of the positioning shell 708 One side of the cavity is fixedly connected, the inner cavity of the extrusion block 710 is inserted with a baffle 712, the protection mechanism 7 also includes a hydraulic rod 701 fixedly connected to one side of the inner cavity of the mounting shell 6, the extended end of the hydraulic rod 701 is fixedly connected to the movable plate 702, both sides of the movable plate 702 are fixedly connected to the first movable shell 703, the inner cavity of the first movable shell 703 is hinged with the first movable rod 704, one end of the first movable rod 704 is hinged to the bottom of the support plate 705, the bottom of the support plate 705 is symmetrically slidably connected to two second movable rods 706, one end of the second movable rod 706 is hinged to the second movable shell 707, the bottom of the second movable shell 707 is fixedly connected to the inner bottom of the mounting shell 6, the inner cavity of the baffle 712 is symmetrically fixedly connected to two sliding rods 713, the surface of the sliding rod 713 is slidably connected to a sliding sleeve 714, and one side of the sliding sleeve 714 is fixedly connected to an extension plate 715.

[0024] First, insert the baffle plate 712 into the positioning shell 708, and squeeze the extrusion block 710 through the baffle plate 712. The extrusion block 710 is driven to retract backwards by the tension spring 711, and the baffle plate 712 is clamped and positioned in the extrusion block 710. Then, the tail body 5 of the self-moving machine is moved out, and the movable plate 702 is moved by the hydraulic rod 701. With the cooperation of the first movable shell 703, the second movable shell 707, the first movable rod 704 and the second movable rod 706, the baffle plate 712 on the support plate 705 is driven to move upward, and the baffle plate 712 is moved to the self-moving machine.

With the cooperation of the first movable shell 703, the second movable shell 707, the first movable rod 704 and the second movable rod 706, the baffle plate 712 on the support plate 705 is driven to move upward, and the baffle plate 712 is moved out. Move to both sides of the self-moving machine tail body 5, and adjust the baffle 712 to a suitable length by pulling the extension plate 715 to block the coal splashing during unloading. When the baffle 712 is not needed, similarly, the baffle 712 is driven downward by the support plate 705, and the baffle 712 is stored in the mounting shell 6 for storage.
