The ejector pins 242 can eject the shrimp shell to turn the shrimp shell. When the shrimp shell is placed, the water stored in the shrimp shell is different according to the placing posture of the shrimp shell, and when the shrimp shell is placed with the back facing downwards, the water stored in the shrimp shell is the largest. Because the shrimp shell surface is the curved surface, by the jack-up back, can overturn automatically for the water of storage in the shrimp shell can flow automatically, and finally flow from perforation 610, avoid the remaining water of shrimp shell to influence drying efficiency, can improve drying efficiency and stoving effect greatly. In addition, the elastic lifting of the ejector plate 241 and the middle plate 243 is utilized to play a role of elastic buffering, so that the collision of the lifting process of the ejector plate 241 is buffered, and the damage to equipment caused by the over rigidity of the lifting process of the ejector plate 241 is avoided. In addition, in order to reduce the structural interference, the upper end of the thimble 242 is chamfered, and the diameter of the thimble 242 is smaller than that of the through hole 610.

To avoid structural interference, the wobble drive 260 and the lift mechanism 230 may be operated alternately. Of course, the size of the through hole 610 in the left-right direction may also be designed to be enough for the thimble 242 to relatively rock left and right therein without collision, so that the rocking driving device 260 and the lifting mechanism 230 can work simultaneously to perform synchronous dewatering operation, thereby improving dewatering effect.

In a further embodiment of the present invention, the shaking driving device 260 is a motor, an output shaft of the motor is connected with an eccentric wheel 261, the eccentric wheel 261 is disposed between one of the supporting plates 220 and the sidewall of the drying box 210, and the eccentric wheel 261 can contact with the corresponding supporting plate 220 during rotation and push the supporting plate 220 to shake left and right to drive the shrimp shells to shake left and right to remove the residual moisture therein. Of course, in other embodiments, the shaking driving device may be a telescopic driving mechanism, such as a telescopic motor, a vibration motor, an air cylinder, a hydraulic cylinder, etc., which drives the supporting plate 220 and the tray 600 to shake left and right. As shown in fig. 5, the inner wall of the drying chamber 201 is provided with a mounting table 219 for mounting a motor.

In some embodiments of the present invention, the drying structure 250 is installed on the top wall of the drying chamber 201, the top wall of the drying chamber 201 is provided with an air inlet 212, the drying structure 250 includes a heating structure 251 and a blower 252, the heating structure 251 is used for heating air, the blower 252 is used for conveying the heated air towards the tray 600 below, so as to perform a hot air drying function, and in addition, an air outlet is opened on the side wall of the lower half of the drying box 210, so as to discharge hot and humid air.
