DETAILED DESCRIPTION

[0019] In order to make the purpose, technical solution and advantages of the utility model clearer, the technical solution of the utility model will be described clearly and completely below. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work belong to the scope of protection of the utility model.

[0020] The specific implementation of the utility model will be described below in conjunction with the accompanying drawings:

[0021] like Figures 1 to 5 As shown, a material conveying flow regulating device comprises a connecting pipe 1, a flow limiting mechanism 2 and a protective shell 3. Both ends of the connecting pipe 1 are provided with flanges 11, and the connecting pipe 1 is detachably connected to an external pipeline through the flanges 11. A guide pipe 12 is provided on the end face of the flange 11. When assembling the device, the connecting pipe 1 can be quickly aligned with the external pipeline by using the guide pipe 12, so as to improve the convenience of assembly.

[0022] A fixedly connected flow limiting mechanism 2 is provided inside the connecting pipe 1, and a driving mechanism 4 connected to the flow limiting mechanism 2 is provided in the protective shell 3. A special-shaped baffle 13 is provided inside the connecting pipe 1, and the flow limiting mechanism 2 is fixedly connected to the special-shaped baffle 13. The special-shaped baffle 13 divides the space inside the connecting pipe 1 into two parts, and the flow limiting mechanism 2 is connected to the internal space of the connecting pipe 1, and the material passes through the connecting pipe through the flow limiting mechanism 2. The driving mechanism 4 adjusts the flow rate of the material through the flow limiting mechanism 2 by controlling the opening of the flow limiting mechanism 2. The protective shell 3 is integrated with the connecting pipe 1, and the protective shell 3 includes a shell 31 and a flap 32. The shell 31 provides a certain degree of protection for the flow limiting mechanism 2 and the driving mechanism 4. The freely openable flap 32 facilitates the inspection and maintenance of the components inside the protective shell 3.

[0023] The flow limiting mechanism 2 includes a guide tube 21, a plug body 22 and a telescopic shaft 23. One end of the guide tube 21 is connected to the special-shaped baffle 13 and is circumferentially provided with a plurality of regularly shaped openings 211, which facilitate the control of the flow rate of the material passing through. The other end passes through the connecting pipe 1 and is provided with an internally threaded tube 212 threadedly connected to the telescopic shaft 23. One end of the telescopic shaft 23 is rotatably connected to the plug body 22 inside the guide tube 21, and the other end is connected to the driving mechanism 4. The driving mechanism 4 drives the telescopic shaft 23 to rotate, and the telescopic shaft 23 is threadedly connected to the internally threaded tube 212 to move up and down, thereby driving the plug body 22 to move up and down, and changing the opening of the opening 211. The opening of the opening 211 is linearly related to the up and down movement distance of the telescopic shaft 23, and the flow limiting mechanism 2 stably controls the flow rate of the material passing through. A groove 221 is provided at one end of the plug body 22 close to the telescopic shaft 23, and a bearing 222 is provided in the groove 221. The telescopic shaft 23 is rotatably connected to the plug body 22 through interference fit with the bearing 222. During the rotation of the telescopic shaft 23, since the plug body 22 is rotatably connected, the plug body 22 will not rotate relative to the guide tube 21, thereby reducing the friction between the plug body 22 and the guide tube 21.

[0024] The end of the telescopic shaft 23 away from the guide cylinder 21 is provided with a toothed section that cooperates with the driving mechanism 4. The driving mechanism 4 includes a cylinder 41 and a rack 42. The cylinder 41 is fixedly connected to the protective shell 3. One end of the rack 42 is fixedly connected to the output end of the cylinder 41, and the other end is meshed with the toothed section. The cylinder 41 drives the rack 42 to move, and the rack 42 drives the telescopic shaft 23 to rotate. A guide cylinder 43 that cooperates with the cylinder 41 is provided on the protective shell 3. The telescopic rod of the cylinder 41 passes through the guide cylinder 43 and is fixedly connected to the end of the rack 42. The guide cylinder 43 facilitates the telescopic rod of the cylinder 41 to drive the rack 42 to move along the length direction. The ends of the toothed section close to the internal threaded tube 212 and away from the internal threaded tube 212 are respectively provided with a first limiting ring 231 and a second limiting ring 232. The first limiting ring 231 prevents the telescopic shaft 23 from being separated from the internal threaded tube 212, and the second limiting ring 232 prevents the toothed section from falling too much and being separated from the rack 42.

[0025] The working principle of the specific embodiment of the utility model is as follows: the material flows from one end of the connecting pipe 1 to the other end, and the special-shaped baffle 13 divides the interior of the connecting pipe into two spaces. The guide tube 21 is connected to the special-shaped baffle 13, and a plurality of through ports 211 are provided on the side of the guide tube 21. The material passes through the through ports 211 from one side of the special-shaped baffle 13 to the other side. The cylinder 41 drives the telescopic shaft 23 to rotate, and the telescopic shaft 23 moves up and down and drives the plug body 22 to move, thereby adjusting the opening and closing degree of the through ports 211 and changing the flow rate of the logistics.
