Abstract

A jet flow type automatic aerator comprises a main frame, a floater mechanism, a supporting mechanism and a water-resistance mechanism. The main frame comprises a generator, a connection shaft, a jet flow pipe, a hollow axle, a bush, a sliding bearing, a blade wheel, a circular nut and a strainer. The floater mechanism comprises a pontoon and a square shank. The supporting mechanism comprises a holdfast and a supporting axle. The water-resistance mechanism comprises a water-proof cover and a tarpaulin. The motor bearing drives the hollow axle rolling via connection axle. The bush and sliding bearing are arranged under the hollow axle. The hollow axle and the blade wheel are fixed together by cap nuts. The strainer is arranged outside the blade wheel. The two pontoons are connected as an integral body. A holdfast on the pontoon is connected with the motor via the supporting axle. The utility model is characterized in that: when the passive and active parts of the connection axle are equipped well, a large space will exist in the neutral position of the jaw. An air inlet is arranged on the upper part of the jet flow pipe and relatives to the connection axle, therefore the air can from A to the hollow axle then to the air drain directly and then jet out with water together. A tarpaulin is arranged on the water-proof cover thereby to make the air convect and to avoid being caught in rain. The main frame and the floater mechanism are connected by a regulating stem. The regulating stem can adjust the jetting angle of the main frame thereby to meet the demands of different water depth.
