[0031] Please refer toFigure 1 As shown in FIG. 6, the front of the output hopper 210 is fixedly connected with a winding drum 306, the winding baffle 305 is slidingly connected to the inside of the winding drum 306, the outer surface of the conveyor main body 1 is fixedly connected with a conveying feed pipe 208, and the top end of the conveying feed pipe 208 is fixedly connected with an extension ring 209. With the conveying feed pipe 208, the material can be conveniently conveyed into the conveyor main body 1, and through the extension ring 209, the external pipeline can be connected with the conveying feed pipe 208.

[0032] Please refer to Figure 1 and Figure 4 As shown in FIG. 6, the inside of the winding drum 306 is rotatably connected with a winding rod 307, the winding baffle 305 is sleeved on the outer surface of the winding rod 307, the left end of the winding rod 307 and the right end of the winding rod 307 are both fixedly connected with a rotating disc 308, the side face of the two rotating discs 308 close to each other is both fixedly connected with a torsion spring 309, the ends of the two torsion springs 309 close to each other are respectively fixedly connected with the two side faces of the winding drum 306, the outer surface of the winding rod 307 is fixedly connected with two blocking rings 310, and the side faces of the two blocking rings 310 close to each other are respectively in contact with the two side faces of the winding drum 306. Through the two blocking rings 310, the winding rod 307 rotating in the winding drum 306 can be limited, so that the winding rod 307 stably rotates in the winding drum 306.

[0033] In use, the conveyor motor 204 and the adjusting hydraulic rod 303 are first connected to the power supply. When the screw conveyor is needed to transport materials, it is first placed manually on a level surface. The support structure composed of the support frame 201 and the bottom plate 202 can stably support the screw conveyor in the required position to transport materials. Then, the height of the winding baffle 305 is adjusted manually according to the flow characteristics of different materials. The power supply of the adjusting hydraulic rod 303 fixed to the inner wall of the fixed frame 302 is manually controlled to facilitate the sliding block 304 at the telescopic end of the adjusting hydraulic rod 303 to slide the winding baffle 305 in the two sliding grooves 301. This allows the winding baffle 305 to slide and adjust its height in the output hopper 210. The adjusting hydraulic rod 303 drives the winding baffle 305 to slide within the two sliding grooves 301. While moving, the take-up rod 307 can rotate within the take-up drum 306, allowing the take-up baffle 305, which is fixed outside the take-up rod 307, to be conveyed from the take-up drum 306 into the output hopper 210. The rotation of the take-up rod 307 causes the rotating disk 308 to rotate, which in turn causes the torsion springs 309, which are fixed between the two rotating disks 308 and both sides of the take-up drum 306, to rotate and tighten, thereby accumulating elastic force. When the hydraulic rod 303 is controlled to not pull the take-up baffle 305 and it is necessary to lower the height of the take-up baffle 305, the elastic force accumulated in the torsion springs 309 is released, causing the take-up rod 307 to rotate in the opposite direction within the take-up drum 306. This facilitates the winding of the take-up baffle 305 onto the outer surface of the take-up rod 307, thus allowing the height of the take-up baffle 305 to be easily adjusted according to the flow characteristics of different materials. Then, by controlling the power supply of the conveyor motor 204, the conveyor motor 204 can drive the rotating shaft 205 to rotate, thereby enabling the spiral blades 206 to rotate inside the conveyor body 1. The material to be conveyed is manually conveyed from the conveyor feed pipe 208 into the conveyor body 1, and then conveyed to the output hopper 210 by the rotating spiral blades 206. By setting the output hopper 210, the powder material can be piled up to fill the lower part of the conveyor body 1 first, and the lower part of the entire conveyor body 1 is in a full state. Then, the material passes through the stabilizing layer at an angle above and is scraped up and extruded by the spiral blades 206. The flow rate sensed by the front-end frequency converter is in a relatively stable state, and the conveying speed tends to be stable, solving the problems of unstable conveying and inaccurate metering.

Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model shall be included within the protection scope of the present utility model.
