Universal connection mechanism for screw conveyor

Abstract

The invention relates to the technical field of production of water-soluble fertilizers, and in particular relates to a universal connecting mechanism for a spiral conveyor. The mechanism comprises a main conveying pipe and a secondary conveying pipe, wherein a main transmission shaft is transversely arranged in the main conveying pipe; the secondary transmission shaft is transversely arranged in the main conveying pipe; spiral blades for conveying materials are fixedly connected to the main transmission shaft and the secondary transmission shaft. According to the universal connecting mechanism for the spiral conveyor, a split type right connecting cover is fixed to the main conveying pipe through a bolt; an integral left connecting cover sleeves the secondary conveying pipe; the split type right connecting cover sleeves the integral left connecting cover to movably connect the main conveying pipe and the secondary conveying pipe, so that the main conveying pipe and the secondary conveying pipe can be conveniently mounted and dismounted; in addition, the adjustable angle range is expanded; a limiting block on the integral left connecting cover is inserted into a limiting groove in the inner side of the split type right connecting cover to improve the sealing performance, and thus the overall durability can be greatly improved.

Description

technical field [0001] The invention relates to the technical field of water-soluble fertilizer production, in particular to a universal connection mechanism for a screw conveyor. Background technique [0002] The screw quantitative conveyor uses the rotating screw blade to push the powdery or granular material for conveying. It is widely used in metallurgy, building materials, chemical industry, grain and mechanical processing and other departments. The screw conveyor is generally composed of three parts: the conveyor body, the inlet and outlet, and the driving device. Ordinary screw conveyors can only be used to convey materials in a straight line. In the production of water-soluble fertilizers with a large number of elements, due to production needs or limited by the site, the entrance of the material and the required exit are not on the same straight line, or there are obstacles between the two, and it is necessary to bypass the obstacles for non-linear transmission.
