[0004] In order to solve the problems existing in the prior art, the utility model provides a drum-type blueberry screening device, comprising a conveyor belt and a screening body, a conveyor belt is provided at the top of one side of the screening body, a screening drum is provided inside the screening body, a lower hopper is provided at the bottom of the screening body, a mounting seat is provided inside the screening body at the top of the screening drum, an electric push rod is provided at the top of the mounting seat, and a knocking block is provided at the bottom of the electric push rod at the bottom of the mounting seat.
[0005] Furthermore, both sides of the top of the lower hopper are connected to the screening body through springs, and a buffer pad is provided on the inner side of the lower hopper. The buffer pad is used to buffer the blueberries that fall onto the lower hopper to avoid damage. The vibration generated by the knocking block causes the screening body to vibrate slightly, and the vibration can be transmitted to the lower hopper through the spring, so that the materials accumulated on the lower hopper can be quickly discharged to avoid blockage.
[0006] Further, the knocking block is spaced a certain distance from the top of the two ends of the screening drum, and the bottom of the knocking block is an arc-shaped surface. The knocking block with the arc-shaped bottom surface is adapted to the circular screening drum, so that the knocking work is convenient.
[0007] Furthermore, the top of the knocking block is connected to the bottom of the electric push rod, and the electric push rod is electrically connected to the timing control component. The timing control component controls the electric push rod to start at a fixed time, and drives the knocking block to perform reciprocating telescopic motion through the electric push rod.
[0008] Furthermore, both ends of the screening drum are connected to the screening body through shaft seats, and the shaft seat at the other end of the screening drum is connected to the output end of the driving motor through a shaft rod. After the driving motor is started, the shaft rod is driven to rotate on the shaft seat, and the screening drum is driven to rotate through the rotation of the shaft rod.
[0009] Furthermore, a guide plate is provided between the screening rollers, and the mesh sizes of the screening rollers are all different. The screening rollers with different mesh sizes cooperate to rotate to screen the blueberries by size, and the guide plate can transfer the blueberries to the next screening roller.
[0010] Compared with the prior art, the beneficial effects of the utility model are:
[0011] During the screening process of the utility model, after the electric push rod is started, it can drive the knocking block to reciprocate and extend. When the knocking block extends out to knock the screening drum, the blueberries on the screening drum bounce up with the vibration generated by the knocking, so that the blueberries stuck in the mesh can be vibrated out, avoiding the blueberries stuck in the mesh and being squeezed and damaged. The vibration generated by the knocking block makes the screening body vibrate slightly, and the vibration can be transmitted to the lower hopper through the spring, so that the material accumulated on the lower hopper can be quickly discharged, avoiding the situation of blockage, thereby increasing the practicality of the device.
