Description

Double screw feeder

technical field

The utility model relates to a conveying device, in particular to a double-screw feeder used for conveying garbage.

Background technique

At present, in the garbage disposal, the garbage feeder used for garbage transmission is a feeder in the general sense. The common mine feeder on the market is mainly used to transfer materials from storage bins or other storage equipment. Evenly or quantitatively supplied to the receiving equipment, used in crushing and screening production lines in mines, gravel yards, metallurgy, building materials, chemicals, mineral processing, coal mines and other industries. The garbage feeder is specially designed for the garbage generation pipeline, which requires the delivery of household garbage to be more uniform in the feeding process, and can control the supply volume, so as to realize the automation of assembly line operation.

Utility model content

In order to solve the above-mentioned defects of the prior art, the purpose of this utility model is to provide a double-screw feeder with fast transmission and high conveying efficiency.

The technical solution adopted by the utility model for achieving the above purpose is: a double screw feeder, including a base frame 1, two groups of screw feeding devices are installed in parallel on the base frame 1, and the screw feeding devices include sequentially installed on The frequency conversion motor 2 with reducer on the bottom frame 1, the transmission shaft 4 is installed on the bottom frame 1 through the bearing seat 5 and the bearing seat 6, the transmission shaft 4 is linked with the frequency conversion motor 2 through the coupling 3, and the screw conveying shaft 8 is installed In the cabinet 9 placed on the bottom frame 1, the screw conveying shaft 8 is connected with the transmission shaft 4 in linkage, and the feeding port 10 is arranged at the upper part of the front part of the cabinet 9, and the discharging port 7 is arranged at the lower part of the tail part of the cabinet 9 .

The screw transmission shaft 8 is welded by a main shaft 81 and a spiral fan blade 82. The main shaft 81 is welded with seamless steel pipe and round steel.

The beneficial effects of the utility model are as follows: the utility model adopts two parallel and uniform screw conveying shafts for conveying, and each shaft can carry out forward and reverse rotation through a frequency conversion motor to directly drive the material from one end to the other end, and can The rotation speed of each screw shaft is adjusted through the console. The material enters from the feed port of the chassis and then rotates through two parallel and uniform screw shafts, and the material is evenly transported to the discharge port through the screw blades. When encountering a blockage of large objects, the PLC will control the automatic positive and negative rotation to discharge the large objects. If there is no discharge or other reasons, there is an inspection door on the side wall of the screw feeder, and the fault can be manually eliminated. The utility model will be further described below in conjunction with the accompanying drawings and specific embodiments.
