The vibration shakeout section is an exposed part of the front vibration conveying groove in front of the shot blasting chamber, and is divided into an upper layer and a lower layer, wherein the upper layer is a grid and is used for impacting casting shakeout and conveying the casting; the lower layer is a steel plate and is used for conveying sand, nails, flashes, burrs and the like falling from the upper layer, when the casting is molded by sand casting, a large amount of sand, nails, flashes, burrs and the like which impact the casting and fall into the lower layer are transversely conveyed out by falling into the belt conveyor 16 from an outlet at the lower end of the section, and at the moment, the casting is provided with a small amount of sand after vibrating and falling; when the casting is molded by non-sand casting, the section directly conveys the upper falling objects to a pit funnel at the lower part of the shot blasting chamber.
The belt conveyor 16 is transversely arranged, is crosswise arranged with the vibration conveying groove and is positioned at the lower part of the tail end of the steel plate of the vibration shakeout section.
The shot recovery section is an exposed part of the rear vibration conveying groove behind the shot blasting chamber, and is divided into an upper layer and a lower layer, wherein the upper layer is a grid and is used for conveying castings after sand falling and shot blasting cleaning and shaking off residual shots in uncomplicated inner cavities of the castings; the lower layer is a steel plate and is used for conveying the shot falling from the upper layer to the bottom outlet at the tail end part of the vibration conveying groove and conveying the shot to the pit hopper at the lower part of the shot blasting chamber by the screw conveyor 12 at the lower part of the steel plate.

When the longitudinal partition 1503 and the impeller head 4 corresponding to the lower part of the shot blasting cleaning section are thrown, the jet directions of all the shots in the range of the fan-shaped angle alpha in the circumferential direction of the impeller blade of the impeller head 4 are matched. Each partition plate is designed according to different angles, the longitudinal partition plates meet the requirement of normal conveying of castings on the upper portion of the grid and correspond to alpha angles of shot jet flows of the shot blasting devices on the lower portion, the size of the alpha angles is determined by setting windows of the shot blasting device orientation sleeves, the direction of the shooting angle of each shot in the range of the alpha angles is different, and the shooting angle of each shot in the range of the alpha angles follows a certain movement rule, so that the design angle corresponding to each longitudinal partition plate in the range also follows the shot flying direction of the movement rule. The three parts of the corresponding structure grid 15 for shot blasting can be welded parts formed by wear-resistant steel plates or wear-resistant steel castings.
The structure of the corresponding structure grid 15 for shot blasting can lead the shot blasting device 4 arranged below the vibrating conveying groove to throw the shot to be subjected to only small resistance when passing through the part, thereby leading the shot blasting quality on the upper part and the lower part of the cleaned casting to be basically the same. The ejection principle of the impeller head 4 is that the jet direction of each shot refers to the jet direction of all the shots within the range of the scattering angle beta formed by the shot in the width direction of the impeller blade of the impeller head and the fan-shaped scattering angle alpha of the impeller blade of the impeller head in the circumferential direction when the impeller head ejects the shot.
