Kitchen waste pretreating and sorting device

Abstract

The invention provides a kitchen waste pretreating and sorting device and belongs to the field of waste treating equipment. The kitchen waste pretreating and sorting device solves the problems of jamming and hole blocking of an existing sorting machine and mainly comprises a machine frame, a box, a material pushing mechanism and a sieve plate. The material pushing mechanism is arranged in the box and installed on the machine frame in a tilting mode; a fixing shaft of the material pushing mechanism is below a crankshaft; a plurality of swing rods with crank arms are sequentially installed on the fixing shaft; each crank on the crankshaft driven by a hydraulic motor is connected with the corresponding crank arm on the swing rod through a connected rod; the included angle between every two adjacent cranks is 90 degrees; an anti-jamming spring extensible material pushing swing head is arranged at the lower end of each swing rod; the sieve plate is an arc-shaped dynamic sieve plate with rollers and comprises the rollers, roller shafts and arc-shaped roller baffles; the roller shafts are installed on the roller baffles correspondingly; and each roller is installed on the corresponding roller shaft between every two roller baffles. The kitchen waste pretreating and sorting device has the characteristics of even material pushing with no jamming, good sieve penetrating performance, high sieving and sorting efficiency, and the like, and is suitable for sieving and sorting of all kinds of kitchen waste.

Description

technical field [0001] The invention belongs to the field of garbage treatment equipment, and mainly relates to a kitchen garbage pretreatment and sorting device capable of finely and quickly sorting kitchen garbage. Background technique [0002] The composition of food waste is relatively complex. In addition to a large amount of organic food waste, there are also impurities such as tableware, packaging and metal, which brings certain difficulties to the classification and recycling of waste. The existing utility model patent "kitchen waste sorting device" is provided with a plurality of swing legs on the horizontal axis above the screen, and the swing legs are fixed on the horizontal axis evenly and parallel to each other, and the swing is driven by the swing motor above. The dial located at the lower end of the swing foot is used to dial and sieve the food waste on the sieve surface. Since the swing foot is composed of a pole and a dial fixed at the lower end of the pole...

AI Technical Summary

Problems solved by technology

Since the swing foot is composed of a pole and a dial fixed at the lower end of the pole, it is easy to get stuck between the dial and the screen when encountering hard impurities in the garbage, which affects the normal screening operation.

In addition, if there are large impurities stuck in the mesh of the screen, it is difficult to clean up because the mesh is a fixed hole for processing.
