Description

Technical Field

[0001] The utility model relates to the technical field of solid material conveying, in particular to a screw conveyor. Background Art

[0002] A screw conveyor is a machine that uses a motor to drive the screw to rotate and push materials to achieve the purpose of conveying. Figure 1 The figure shows a common screw conveyor 100. The material enters the tube shell 1 from the feed port 11, and is evenly distributed in the tube shell 1 under the push of the screw auger 2, and is discharged from the discharge port 12. A major advantage of the screw conveyor is that it can feed at a constant speed without clogging, because the rotation of the screw auger 2 can quickly and evenly distribute the material in the tube shell 1.

[0003] Screw conveyors are mostly used to transport granular materials and powders. One of the major advantages of screw conveyors is that they can achieve constant speed feeding, especially in some occasions where the application amount is relatively high, such as feed or drug preparation. However, some materials have strong adhesion and are prone to clogging. Although the screw auger 2 can ensure that there is no clogging in the tube shell 1, during the feeding process (for example, Figure 1 There is no measure to ensure that the feed pipe 111 is not blocked. Once the material has strong cohesiveness and is blocked in the feed pipe 111, the existence of the spiral auger 2 is of no avail, which obviously has an adverse effect on the constant speed and quantitative discharge. At this time, the operator has to stop the machine for maintenance, resulting in a loss of efficiency and time.

[0004] The utility model provides a screw conveyor to solve the problem of blockage in the feeding process. Utility Model Content

[0020] In order to provide a further understanding of the purpose, structure, features, and functions of the present invention, the present invention is described in detail below with reference to the embodiments.

[0021] Figure 2 Shown is a schematic structural diagram of a screw conveyor according to an embodiment of the utility model. Figure 3 Shown Figure 2 A schematic diagram of the partial structure of the embodiment shown.

[0022] like Figure 2As shown, the utility model provides a screw conveyor 200, including: a tube shell 1, the tube shell 1 is respectively provided with a feed port 11 and a discharge port 12 at both ends; a spiral auger 2, the spiral auger 2 is arranged in the tube shell 1; a silo 3, the silo 3 is arranged at the feed port 11; and a stirring module 4, the stirring module 4 includes a stirring shaft 41 and a stirring blade 42, the stirring blade 42 is arranged at the end of the stirring shaft 41, the stirring shaft 41 extends vertically, and the stirring blade 42 extends into the vicinity of the spiral auger 2. The screw conveyor 200 also includes a silo cover 31, and the stirring shaft 41 passes through the center of the silo cover 31. The stirring shaft 41 is driven to rotate by a motor 5, and the motor 5 is located above the feed port 11. Under the stirring of the stirring shaft 41, the material in the silo 1 can smoothly enter the tube shell 1 without congestion.
