detailed description

Below in conjunction with accompanying drawing and specific embodiment the utility model is described in further detail.

As shown in Figures 1 to 3, the multifunctional single-ear rice thresher of the present embodiment includes a frame 1, and the frame 1 is provided with a threshing chamber 2 with a threshing drum inside, and a joint with a rotating twist piece inside. Material chamber 3, air-flow type separation material cylinder 4 and a driving mechanism for driving the threshing drum and the rotary blade to rotate. The top of the threshing chamber 2 is provided with a feed hopper 5, and the material receiving chamber 3 communicates with the bottom of the threshing chamber 2. The air-flow separation material barrel 4 is provided with a top outlet 41 at the top, a bottom outlet 42 at the bottom, and a side inlet 43 at the side. The side inlet 43 communicates with the material receiving chamber 3, and the top outlet 41 is connected to an exhaust fan through the pipeline 7. 6 are connected, the outlet of exhaust fan 6 is connected with debris discharge port 8, and the bottom outlet 42 is connected with discharge port 9.

When the multi-functional single ear rice thresher of this embodiment is working, the driving mechanism and the exhaust fan 6 are started, and the harvested rice is artificially fed into the feeding hopper 5 at the top of the threshing chamber 2, and the rice passes through the threshing drum in the threshing chamber 2. After threshing, the separated millet and sundries enter the material receiving chamber 3, the rotation of the rotating blade in the material receiving chamber 3 and the airflow formed by the operation of the exhaust fan 6 suck the millet and sundries into the airflow and separate them out of the material cylinder 4 , due to the principle of gravity, the millet is heavier than the impurities, and is discharged through the bottom outlet 42 at the bottom of the barrel 4 through the airflow type separation.
