Problems solved by technology

Household garbage enters the conveying shell from the feeding port above the conveying body, and the reducer starts to drive the two screw shafts to rotate respectively. It also has the function of avoiding blockage for large block materials. This structure has a good dredging effect, but there are other shortcomings. First, the spiral blade has a central shaft structure, which takes up a large space. Compared with the shaftless blade It is more likely to cause blockage, and the second is that when one of the fixed shafts or one of the moving shafts fails, the entire machine will have to stop working, and it needs to be repaired before it can continue to run. , because the bottom side of the fixed shaft and the moving shaft are connected, the extrusion of the material during operation will cause great damage to the other shaft, and it is extremely inconvenient to clean the material in the tank during maintenance

Abstract

The double screw feeder includes one casing, two sets of parallel no-axle screw blades inside the casing, and two driving motor devices to drive these two sets of parallel screw blades separately. The casing has discharge port in the tail, two parallel semi-circular channels corresponding to these two sets of parallel screw blades separately and with lining board, and one connecting board to connect the near ends of two semi-circular channels. The present invention is suitable for feeding lumpy and easy-to-twist material and has great feeding space, stable structure and easy maintenance.

Description

technical field [0001] The invention relates to a garbage conveying device used in garbage treatment, in particular to a screw feeder. Background technique [0002] In the existing garbage disposal industry, the screw conveyor specially transporting the original domestic garbage has a single-axis screw structure, and its transmission is simple, closed operation, and it is very convenient to transport powder, granular or small pieces of materials. However, for bulky or easily entangled garbage, it is very easy to block and entangle the garbage, which will affect the transportation, and even cause the transportation to fail and stop. In order to overcome this problem, the applicant also applied for a tubular screw machine on June 14, 2006. It adopts a structure without a center shaft, which greatly increases the channel space for conveying materials inside the outer cylinder, increasing the material The delivery flow reduces the blockage, but on the whole, the delivery volume...
