In this embodiment, by using the open port 8, the roller 2 and the pusher frame 28 together, the purpose of quickly feeding sweet potatoes before washing and quickly unloading them after washing and conveying them to the crushing station is achieved, which significantly improves the material transfer efficiency.

[0014] Furthermore, through the combined action of the cleaning brush 10 inside the drum 2 and the feeding plate 13 on the hollow tube 12, the sweet potatoes are fully turned over and washed inside the drum 2. Combined with the coordinated shearing and crushing of the two crushing rollers 35, the cleanliness and crushing uniformity of the final product are significantly improved.

[0015] Working principle: When using the device, the opening 8 at the top of the drum 2 is initially facing upwards and connected to the outlet of the hopper 9. The sweet potato raw material is directly fed into the drum 2 through this opening. Then, the drum 2 is rotated so that the opening 8 is misaligned with the hopper 9, so that water will not splash from the hopper 9 to the outside when sprayed. Subsequently, the motor 15 is started, and the hollow tube 12 and the material-pulling plate 13 on it are driven to rotate inside the drum 2 through the meshing of gear 16 and gear 2 17, thereby turning the sweet potatoes and allowing them to be brushed by the cleaning bristles 10. At the same time, external water is sprayed into the drum 2 through the rotary joint 18 and the water spray hole 14 on the hollow tube 12 for rinsing. The mud and water generated by brushing are discharged through the water permeable hole 11 on the arc-shaped mounting plate 5 and fall down, and finally discharged through the drain pipe 27 at the bottom of the processing box 1. After cleaning is completed, the motor 2 40 is started, and the transmission shaft 21 drives the water flow. The meshing of the worm gear 22, worm wheel 23, and gear 24 with the gear ring 19 drives the roller 2 to rotate, causing its opening 8 to face downwards. The cleaned sweet potatoes fall through the opening 8 onto the mesh plate 26 below under the action of gravity and are located inside the pusher frame 28. Then, the motor 32 starts and drives the lead screw 33 to rotate, causing the pusher frame 28, which is connected to it through the sliding nut 29, to slide to the right along the surface of the mesh plate 26, pulling the sweet potatoes in the frame out of the connecting groove 25, so that they are guided by the guide plate 34 at the top of the crushing box 3 and fall between the two parallel crushing rollers 35. The motor 47 starts and drives the two crushing rollers 35 to rotate in opposite directions through the meshing drive gear and driven gear in the gearbox 36, squeezing and tearing the sweet potatoes to complete the crushing. The crushed sweet potato particles finally fall into the receiving box 39 located at the bottom of the crushing box 3 in the pull-out groove 38, completing the entire process.

[0016] It should be noted that, in the specific implementation of this technical solution, the motors 15, 40, 32, and 37 can be configured with conventional motor drive control systems (such as PLC-based controllers, relay circuits, or frequency converters). Although such control systems are not described in detail in this technical solution, they are components that can be conventionally selected by those skilled in the art based on the actual action sequence and power requirements. Their circuit connections and control logic follow well-known technologies in this field and do not affect the implementation of the core innovation of this solution. In practical applications, this system is mainly used to coordinate the rotation and positioning of the drum 2, the rotation of the hollow tube 12, the reciprocating motion of the pusher frame 28, and the start and stop of the crushing roller 35. However, its specific type and connection method can be adjusted according to production requirements, all of which fall within the reasonable extension range of this technical solution.

[0017] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely preferred examples and are not intended to limit the utility model.
