The utility model discloses an exhaust port structure for a PVB single screw extruder, which comprises an extruder main body, one side of the top of the extruder main body is respectively provided with a mounting pipe and an air outlet, the inner side of the mounting pipe is sleeved with an exhaust pipe, the top of the exhaust pipe is provided with a cleaning mechanism, and the outer side of the exhaust pipe is provided with a fixing mechanism. An annular plate is mounted at the top of the mounting pipe; the exhaust pipe is connected to the inner side of the mounting pipe in a sleeving manner, so that the exhaust pipe can be directly rotated to adjust the exhaust direction, gas can be exhausted to a specified direction under the arrangement of the L-shaped structure of the exhaust pipe, the influence of the exhausted gas on workers is avoided, and the working efficiency is improved by utilizing the structural adjustment of the fixing mechanism. The exhaust pipe rotating by an angle can be conveniently positioned, rotation of the exhaust pipe is avoided, and the adjusting flexibility and the fixing effect of the exhaust pipe are improved.

The utility model discloses a kind of grain screening devices for smart agriculture, including support frame, U-shaped connecting frame is movably arranged on support frame, several filter plates are arranged on U-shaped connecting frame, the arrangement of several filter plates is arranged in perpendicular inclination state from top to bottom by the way of aperture from big to small, double-shaft motor is installed on support frame, eccentric wheel is installed on the two output shafts of double-shaft motor, eccentric wheel is connected with connecting rod, another end of connecting rod is connected with transmission shaft, transmission shaft is fixed at the bottom of U-shaped connecting frame, in the utility model, by several filter plates from top to bottom, the setting of aperture gradually reduces, the different size of grain particle is distinguished and screened, thereby realizing the fine screening of grain particle, further improve the precision of grain screening, satisfy the production demand of fine screening of grain.
