It is widely used in chemical, fertilizer, new energy, pesticide intermediates and other industries. The current powder material conveyor has been improved in many aspects, making it have higher dust and odor resistance, safety and stability. There is a double-channel material conveyor, and the interior of the double channel is a reciprocating enclosed space; one channel is the material conveying space from the feed end to the discharge end, and the other channel is the return chain space from the discharge end to the feed end.

[0003] When installing a dual-channel material conveyor, pipelines are laid according to the starting and ending points of the conveyed materials. Some pipelines are laid on the ground, while some pipelines need to be erected in the air. When installing and docking the pipelines, the existing connection technology generally uses multiple bolts and nuts to tighten them. However, for a system that needs to lay a long pipeline, tightening a large number of bolts is cumbersome, resulting in low pipeline laying efficiency. For pipelines erected at high places, workers need to work at heights, and long-term climbing work will undoubtedly increase safety risks. Furthermore, when the powder material conveyor is put into use, it will encounter temporary use. At this time, the entire powder material conveyor needs to go through the installation and disassembly process.

[0042] Reference Figure 8 The two ends of the arc plate 20 are rolled outward and are arranged in a flared shape; the shape of the two ends of the arc plate 20 helps the end of the wire rope 14 to penetrate into the casing 13 to prevent the end of the wire rope 14 from hitting the casing 13 or the cross-section of the arc plate 20.

At this time, the plug plate 5 restrains the radial separation tendency of the pipe body 1, and the extrusion block 7 restrains the axial separation tendency of the pipe body 1, so that the two pipe bodies 1 are connected together; the pipe body 1 cooperates with the setting of the clamping assembly to reduce cumbersome operations, improve assembly and disassembly efficiency, make the splicing of the pipe body 1 more convenient, and can quickly realize the laying of the pipe body 1. At the same time, it is more suitable for the installation and disassembly of temporary conveyors;

[0045] The rod body 9 is connected to the plug plate 5 through a spring sheet. When the plug plate 5 is inserted into the bayonet 3, the bayonet 3 squeezes the rod body 9, and two adjacent rod bodies 9 are close to each other. When the plug plate 5 is inserted to the bottom of the bayonet 3, the rod body 9 is embedded in the arc-shaped opening 8, and the plug plate 5 is constrained in the bayonet 3, which also plays a role in stabilizing the connection between the clamping assembly and the connecting plate 2, so as to prevent the vibration generated during the operation of the powder material conveyor from vibrating and loosening the connecting plate 2;

[0046] The ends of the tube body 1 are butted together, and the positioning assembly is embedded between the two connecting plates 2. The insert tube 11 is inserted into the positioning hole 10.

The thickness of the middle plate 12 is controlled at 1MM, which will not affect the sealing between the two connecting plates 2. The insert tube 11 is inserted into the positioning hole 10, so that the two tube bodies 1 can be quickly aligned when they are butted, which is convenient for the installation of the clamping assembly.

[0047] The steel wire rope 14 penetrates into the sleeve, connects the sleeves 13 on the two adjacent connecting plates 2 in series, and the steel wire rope 14 annularly binds the clamping assembly to the pipe body 1, thereby improving the integrity and stability between the clamping assembly and the pipe body 1; the steel wire rope 14 penetrates into the sleeve 13, and the diameter and hardness of the steel wire rope 14 itself will squeeze the push rod 16, and the push rod 16 squeezes the spring 17 and moves toward the rod body 9, and the end of the push rod 16 pushes the push rod 18, and the push rod 18 squeezes the extrusion sheet 19 on the rod body 9, and squeezes the rod body 9 toward the arc-shaped opening 8, thereby improving the clamping stability between the rod body 9 and the arc-shaped opening 8, and once again improving the connection stability between the clamping assembly and the pipe body 1, and also improving the connection stability between adjacent pipe bodies 1;

[0049] The pipe body 1 is erected in the air and needs an external support to hold it. The existing support is directly fixed on the pipe body 1, and there is no room for buffering. When the pipe body 1 is running, vibration is generated, which will be transmitted to the support, affecting the stability of the support. For this reason, a compression spring 23 is also provided in this embodiment. After the pipe body 1 is spliced, the connecting rod 21 is inserted into the insert tube 11, and then the connecting rod 21 is fixed on the insert tube 11 using a screw 26 in conjunction with a nut, that is, the connecting rod 21 is fixed on the pipe body 1. At this time, the spherical shell 24 is connected to the connecting rod 21 through the compression spring 23, and the clearance hole 25 is gap-fitted with the connecting rod 21. When the pipe body 1 vibrates, the compression spring 23 buffers part of the vibration force, and the connecting rod 27 is fixed on the external support to reduce the vibration coordination of the support and ensure the stable operation of the pipe body 1; the arc-shaped limit plate 28 limits the range of axial movement of the spherical shell 24 along the connecting rod 21 to prevent the pipe body 1 from swinging too much, resulting in loosening and falling apart between adjacent pipe bodies 1.
