The application relates to an inlay type patch material distributing device for drip irrigation belts and relates to the technical field of inlay type patch production for drip irrigation belts, which comprises a material distributing mechanism, a leftover material conveying mechanism, an inlay type patch conveying mechanism and a screening mechanism. The application carries out secondary screening on the material preliminarily separated through the gap of the material distributing mechanism by arranging the screen in the screening mechanism. When the material falls to the screen, the forward and reverse motor drives the rotating rod and the cam to rotate, the cam cooperates with the lower surface of the screen to make the screen vibrate. Under the vibration, the qualified inlay type patch with small size can smoothly pass through the screen mesh hole and fall to the upper surface of the inlay type patch conveying mechanism, while the unqualified patch and leftover material with large size are intercepted, high-precision separation of the patch and the leftover material is realized, the problem that the traditional device cannot completely separate is solved, and the problems of patch adhesion and stacking are effectively solved.

The utility model discloses a kind of steel sand recycling screening devices of shot blasting machine, it is related to shot blasting machine technical field, including selection device main body, the upper surface of screening device main body is provided with feed pipe, and the lower surface of feed pipe is provided with support frame, the upper surface of support frame is provided with vibration device, and the both sides surface of support frame is provided with elastic restorer, and the front surface of support frame is provided with discharge plate.The steel sand recycling screening device of shot blasting machine, compared with the shot blasting screening recycling device of existing ordinary shot blasting machine, by the setting of double layer screen mesh hole plate, steel sand can be graded and screened by the setting of size hole, improve screening speed, reduce the frequency of steel sand jam in screen mesh hole plate simultaneously;By the setting of connecting plate one, double layer screen mesh hole plate can be extracted between to carry out quick update maintenance, to improve the maintenance speed of screen mesh hole plate, improve the working efficiency of screening device.
