[0003] The discharging screw is a common and important material conveying equipment, which is widely used in various material conveying scenes due to its stable conveying capacity and relatively simple structure. The traditional discharging screw mainly comprises a feeding port, a spiral blade, a screw shaft, a shell and a driving device. When in operation, the materials enter the closed inner cavity of the shell through the feeding port, the power output by the motor drives the screw shaft to rotate at high speed, the screw shaft drives the spiral blade connected thereto to rotate synchronously, and in the rotation process of the spiral blade, the spiral structure formed by the spiral blade applies a pushing force to the materials, pushes the materials along the predetermined path in the shell, and continuously moves towards the discharging port, so as to complete the conveying of the materials.
[0004] However, the existing discharging screw has certain limitations in use: the feeding port part and the shell part of the existing discharging screw are mostly formed into a relatively fixed structure by welding, bolt fastening and the like, so the discharging direction of the existing discharging screw is relatively fixed, and the adaptability is limited. When the processed materials need to be conveyed to different packaging equipment in the packaging area or temporarily stored in storage containers at different positions in actual production, a series of complex pipe connection systems need to be added to change the flow direction of the materials through elbows, tees and other pipe fittings, so as to greatly increase the equipment procurement, installation and maintenance costs. At the same time, after the number of pipes increases, the materials are prone to be blocked and left in the conveying process, which reduces the production efficiency, and even a large amount of manpower, material resources and time cost need to be consumed.
