Abstract

The invention discloses a safe and high-efficiency grain air injection screening device. The safe and high-efficiency grain air injection screening device comprises a feeding pipe, a screening box, amaterial shaking plate, a dust collector, a rotary drum, scraper plates, bristle brushes, a filter plate, an aerating device, an inclined guide plate and a rotary motor. The feeding pipe is arranged at the top end of the screening box. The material shaking plate is arranged in the screening box. The top end of the screening box communicates with the dust collector. A dust collection pipe is arranged on the dust collector. A dust collection port is formed in the outlet end of the dust collection pipe. The inner walls of the screening box are movably connected with the two ends of the filter plate. A discharging pipe is arranged on one side of the screening box. The screening box communicates with the aerating device. The rotary drum is arranged above the filter plate. The scraper plates arearranged on the outer edge wall of the rotary drum. The bristle brushes are arranged at the ends of the scraper plates. Full grain is screened out, meanwhile, the situation that dust and other thingsfly to the air and affect the air quality is avoided, the health safety of the working environment is improved, the safety and health of respiratory tracts are ensured, the working efficiency and effect are improved, and the safe and high-efficiency grain air injection screening device is simple in structure, convenient to use and beneficial for popularization.

Description

technical field [0001] The invention relates to the field of agriculture, in particular to a safe and high-efficiency air jet screening device for grain. Background technique [0002] Agriculture has been the foundation of the national economy since ancient times, in order to realize the economic take-off and the improvement of the comprehensive strength of our country. Our country has been exploring the path of agricultural development, and has made great achievements in agricultural technology, economy and various aspects. But now China's agriculture has problems in society, economy and ecology, which seriously restrict the development of agriculture. The development of my country's agriculture must set clear goals, choose an agricultural development model suitable for my country's actual conditions, and finally realize agricultural modernization. For a long time, it is an indisputable fact that the profit level of agricultural production is not high. On the one hand, it...
