Abstract

The utility model relates to a simple-structured and clean-threshing automatic thresher for rice and wheat, which comprises a machine frame, a basic shaft, a threshing drum, a conic barrel, a sieve plate and a cleaning blower. The utility model is characterized in that the basic shaft as well as the axle bearing is fixed on the machine frame; along the transverse direction of the automatic thresher for rice and wheat, an eccentric shaft, the threshing drum and the conic barrel are arranged orderly on the basic shaft; a fixed sieve and a vibration sieve are arranged under the threshing drum; a cleaning blower is arranged on one end of the basic shaft, the upper air intake of the blower is opposite to the top part of the threshing drum and the lower part is opposite to the vibration sieve through a cleaning drum. The automatic thresher for rice and wheat can complete the process steps of feeding, threshing, screening and bagging seeds continuously, and the work efficiency is improved.

Description

Automatic thresher for rice and wheat

The utility model relates to a kind of agricultural machinery, particularly a kind of rice wheat automatic thresher.

Need artificial hand to take straw threshing on the cylinder of rotation during traditional rice-wheat threshing machine operation, seed also need manually be cleaned.Though the thresher after the improvement increases by a cover seed cleaning plant, more complicated needs two cleaning fans of coaxial installation arranged side by side; weeds that siphon away in the cylinder, foreign material that siphon away in the seed, body heaviness; personnel selection is many, and labour intensity, threshing cleannes are low.

The purpose of this utility model provides a kind of simple in structure, the threshing cleannes are high and can finish threshing continuously, clean, the rice wheat automatic thresher of seed pack.

The purpose of this utility model is achieved in that rice wheat automatic thresher comprises frame; main shaft; threshing cylinder; conically shaped; sieve plate and cleaning fan; main shaft by bearing fixing on frame; along rice wheat automatic thresher laterally; setting-up eccentricity axle successively on main shaft; threshing cylinder and conically shaped; support one end that is arranged on the main shaft below is fixed on the frame; the other end and connecting lever flexibly connect; this connecting lever is connected with the vibratory sieve that is arranged on the threshing cylinder below; the lower end and the food output groove of vibratory sieve join; one gravity flow screen is set between threshing cylinder and vibratory sieve; one scourclean also is set below conically shaped; end at main shaft is installed a cleaning fan; the air inlet of blower fan is divided into two parts up and down, and top is facing to the end of threshing cylinder, and the lower part faces toward vibratory sieve by scourclean.

The utility model will be further described below in conjunction with accompanying drawing.
