Mechanical screw conveyor device, tensioning and flexible traction component composition drive wheel main structure, therefore, they are often referred to as the lead components of flexible conveyor device. Screw conveyor is different, fluent strip is based on as the main component of the material transport to achieve a rigid screw, often referred to as the conveyor device of rigid "traction" members. Screw conveyor machine commonly known as the transport of bulk material conveyor equipment is continuous horizontal or vertical aspects of the short distance.

Its main characteristics are: simple structure, small size, low cost, good sealing, can be discharged into the more points, the material has a mixing effect, but its small short distance transportation, housing and blade wear, more energy high material crushing effect is stronger.

According to the structure characteristics and performance of the fluent strip, screw conveyor equipment is usually used for conveying materials in the production process of grain and oil, feed plant. It should be noted that it should not transmit blocks, more fiber impurities, wear resistance, easy to break or easy to bond materials, so as not to lead to clogging and broken materials. According to the installation in the form of fluent conveyor equipment can be divided into horizontal and vertical slow two fixed and mobile, according to the transmission direction or speed, can be divided into work in engineering practice more commonly used a fixed, horizontal screw conveyor slow.

First, as shown in the structure and working principle 1 of the general structure of the structure of the part of the horizontal screw conveyor device, it consists of a screw, bearings, grooves, projected out and driving device. A rigid screw passes through the head, tail and middle portion of the groove bearing, and a fluent strip is formed to form the rotating member capable of achieving material handling. The magnetic head drive operates the screw device through mounting, the rear side of the chute on the material inlet and outlet is opened and the lower side of the head.
