Embodiment Construction

[0030] Embodiments of the present invention are described in further detail below in conjunction with the accompanying drawings:

[0031] The present invention is a combination cleaning screen for multi-stage sorting of grain, which is composed of three parts: a screen box 18, a grain cleaning device 2 and a chain-type brush plate mechanism. The sieve box 18 is an integral sieve box, which is welded by multi-layer sieve plates 14 with different apertures, and the lower end is provided with a large miscellaneous outlet 15, a small miscellaneous outlet 17 and a grain net object outlet 16. Integral sieve box 18 is suspended in the body 10 by four cantilever arms 22. Driven by motor 20 and eccentric connecting rod 21, it can swing in the body 10 to carry out gravity screening to grain. The grain cleaner 2 is arranged on the top of the sieve box 18, and the feeding port 1 is located at the upper port of the grain cleaner 2. See figure 1 .

[0032] The body 10 is also provided wi...

Abstract

The invention relates to grain machinery, in particular to a combined cleaning sieve used for grain deep-processing enterprises and multistep sorting before grain warehousing. The combined cleaning device is composed of a sieve box, a grain cleaner and a chain-type brush plate mechanism, the grain cleaner is arranged on the upper portion of the sieve box, the chain-type brush plate mechanism is composed of a driving shaft, a driven shaft, a chain, a brush rod, a brush rod rail and a brush plate combined member and driven independently by a motor, the brush rod is fixed on two chains and driven by the same to be in circulating motion, and in order to prevent vibration of the brush rod during running, two ends of the brush rod are limited in the rail during running. The combined cleaning device has the advantages that the combined cleaning device is compact in structure, high in sorting efficiency, high in yield, stable and reliable in running, low in noise and little in environment pollution and is energy-saving emission-reducing efficient grain sorting equipment.

Description

technical field [0001] The invention relates to a grain machine, in particular to a combined cleaning sieve used in grain deep processing enterprises and multi-stage sorting before grain storage. Background technique [0002] After rice and other grains are harvested, there are a lot of debris such as weeds, straw, rope ends, bricks, stones, glass fragments, etc. Before the grain is put into storage, the debris must be sorted and cleaned. Due to the variety of sundries in grain, they are divided into light miscellaneous (such as rice husk, dust, broken straw, etc.) and heavy miscellaneous (such as sand, gravel, etc.) according to their quality, and divided into large and Miscellaneous and small miscellaneous. At present, the cleaning equipment in the existing grain machinery all has a single function, such as several cleaning equipment such as winnowing and gravity screening. Different equipment has its different performance and characteristics, and also has its own shortco...
