Small-sized beam rotary cleaning and screening machine

Abstract

The invention discloses a small-sized beam rotary cleaning and screening machine. A shell is provided with a motor, a sundry layer, a coarse screening net box and a fine screening box; the motor is arranged on the upper part of the shell; a coarse screening net plate and a cleaning brush are arranged in the coarse screening net box; the fine screening box is arranged under the coarse screening net box; a fine screening net plate is arranged on the middle part of the fine screening box; an air cylinder device is arranged at the lower right corner of the shell; and a push broach, a suction disk and a vibrating block are arranged in the air cylinder device. The coarse screening net box of the small-sized beam rotary cleaning and screening machine is driven by the motor to rotate at high speed to generate a centrifugal force, beans are remained in the net by the net, fine sundries are removed, the vibrating block driven by the air cylinder device vibrates to enable the beans to fall down after the beans arrive at the fine screening box, lightweight sundries are sucked by the suction disk, and the push broach pushes the fallen materials flatly and pushes out the sundries, so that agricultural production is facilitated.

Description

technical field [0001] The invention belongs to the technical field of agricultural machinery, and in particular relates to a small-sized bean rotary cleaning and screening machine. Background technique [0002] At present, the beans harvested in agricultural production are often mixed with many impurities. If the impurities are not removed in time, the storage and sowing will be affected. The traditional manual method of removing impurities is time-consuming, laborious, slow and inefficient. The existing machine removal of impurities is generally Vibrating screening machine, but there is a vibrating device between the screens of the vibrating screening machine, so the vibration is easy to cause uneven force, and the maintenance cost is high. Therefore, a bean screening machine with high screening efficiency and high screening accuracy is needed. Clean beans, etc. features. For example, the new patent with the Chinese patent application number CN201510061799.X discloses a b...

AI Technical Summary

Problems solved by technology

Because the bean screening machine of the present invention is used to store the bean container and a vibrating generator is fixedly connected, the vibration of the vibrating generator can make the bean in the bean storage be layered according to the size, and the impurity with big particle can be left in At the top, it is easy to remove, the whole device has a simple structure and low cost, thus greatly reducing the production cost, but this invention does not perform more accurate removal of impurities on the beans and cannot clean the beans hygienically
