Description

Technical Field

[0001] The utility model relates to the field of screw conveyors, in particular to an anti-blocking mechanism of 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 transportation. It can transport horizontally, obliquely or vertically, and has the advantages of simple structure, small cross-sectional area, good sealing, easy operation, easy maintenance, and convenient closed transportation. Screw conveyors are divided into two types of conveying forms: shaft screw conveyors and shaftless screw conveyors, and are divided into U-shaped screw conveyors and tubular screw conveyors in appearance. In the prior art, screw conveyors are usually used in mixing stations, and materials are transported to designated equipment through screw conveyors. However, during the use of existing screw conveyors, since the screw conveyors do not have anti-blocking measures, once a large amount of material enters the screw conveyor through the feed port, it will easily cause blockage, which requires shutdown for maintenance, thereby reducing the efficiency of the screw conveyor in conveying materials.

[0003] According to the published patent 202321411067.5, a screw conveyor includes a screw conveyor body, an anti-blocking mechanism is set in cooperation with the use of the screw conveyor body, and the second drive motor drives the output end and drives the two-way adjustment screw to rotate through the second rotating rod, so that the symmetrical adjustment plates can make opposite displacement operations along the two-way adjustment screw through the threaded holes opened on the connecting block, so that the feeding amount and feeding speed of the material can be controlled by adjusting the size of the gap formed between the symmetrical adjustment plates, so as to avoid the problem of blockage caused by inputting a large amount of material into the screw conveyor body through the feed port at one time, and The first driving motor drives the output end to drive the stirring roller to rotate through the first rotating rod, and the stirring roller stirs the material through the stirring rod on the outer wall, which can break up the condensed lumps in the material, thereby ensuring that the material will not be blocked when entering the screw conveyor body. In the process of realizing the utility model, the inventor found that at least the following problems in the prior art have not been solved. Although the anti-blocking mechanism is used in conjunction with the use of the screw conveyor body, the second driving motor drives the output end and drives the bidirectional adjustment screw to rotate through the second rotating rod, so that the symmetrical adjustment plate can pass through the threaded hole opened on the connecting block along the double The adjusting screw rod is displaced in the opposite direction, so that the feeding amount and feeding speed of the material can be controlled by adjusting the size of the gap formed between the symmetrical adjusting plates, so as to avoid the problem of blockage caused by inputting a large amount of material into the screw conveyor body through the feeding port at one time, and the stirring roller is driven to rotate by the first rotating rod through the output end of the first driving motor, so that the stirring roller stirs the material through the stirring rod on the outer wall, which can break up the condensed lumps in the material, thereby ensuring that the material will not be blocked when entering the screw conveyor body, so as to ensure the normal conveying efficiency of the screw conveyor body for the material, and solve the problem of the problem of the screw conveyor body being blocked due to the screw conveyor The conveyor does not have anti-blocking measures, which will easily cause blockage once a large amount of material enters the screw conveyor through the feed port, requiring shutdown for maintenance, thereby reducing the screw conveyor's material transportation efficiency. However, during use, the anti-blocking mechanism of the traditional screw conveyor also requires an additional drive motor to drive the stirring roller, resulting in the need to set up multiple drive motors for the screw conveyor equipment, resulting in poor energy efficiency of the equipment. Moreover, only the feed port is stirred to prevent blockage, and there is also a blockage problem at the discharge port due to the large amount of material output. For this reason, a new technical solution needs to be designed to solve the problem. Utility Model Content
