Tube type spiral feeder

Abstract

The invention discloses a tube type spiral feeder which comprises a storage bin fixedly erected on a horizontal working table. The tube type spiral feeder further comprises a pushing device, wherein the pushing device is communicated with a feed port of the storage bin and is used for feeding materials in a pushing mode. The pushing device comprises a hollow feed tube body, a spiral pushing shaft and a variable frequency motor, the spiral pushing shaft is coaxially arranged in the feed tube body, the variable frequency motor drives the spiral pushing shaft to rotate around the axial line of the feed tube body, one end of the feed tube body is communicated with the feed port, and a discharge port is formed in the other end of the feed tube body. The tube type spiral feeder is characterized in that the spiral pushing shaft is sleeved with at least two hanging bearings, and the hanging bearings comprise shaft sleeves coaxially arranged on the spiral pushing shaft in a sleeved mode and hanging arms used for fixing the hanging bearings on the inner wall of the feed tube body in a hanging mode. The tube type spiral feeder solves the problem that the spiral pushing shaft is prone to bending and deformation in the long-distance material conveying process, and has the advantages of being simple in structure, long in service life and even and stable in material feeding.

Description

technical field [0001] The invention relates to a feeder suitable for conveying materials over a long distance, in particular to a tubular screw feeder. Background technique [0002] The horizontal screw feeder is a push shaft driven by a motor in the horizontally erected feeding pipe, and the spiral blade is continuously welded on the push shaft. Driven by the motor, the spiral blade conveys the material from one end to the other end. Uniform and stable, high efficiency, strong adaptability and other advantages. During the working process of the existing horizontal screw feeder, the rotating push shaft will be bent and deformed due to the gravity of the material and the friction generated during the rotation process, especially when the material needs to be transported over a long distance. The length of the push shaft itself is relatively long, and its middle part is prone to be bent downward during the rotation process. Once the push pipe bends, it will no longer be coa...
