[0050] Working principle:

[0051] When in use, the citrus is introduced into the unloading barrel assembly 2, and the PLC controller 11 controls the motor 305 to open the unloading transmission belt assembly 3. The output shaft of the motor 305 rotates to drive the connected first pulley 303 to rotate. The first pulley 303 rotates and drives the second pulley 304 to rotate through the transmission belt 306. The transmission belt 306 meshes and rotates between the first pulley 303 and the second pulley 304. The transmission belt 306 drives the citrus to move downward through friction, and the cutting knife assembly 9 cuts the citrus skin, and then pushes the citrus located at the bottom of the main barrel to move downward in turn. When the lowest citrus moves to the unloading limit structure 4, the citrus abuts against the bottom wheel 403, and pushes the bottom wheel 403 and the slider 404 to move along the axial direction of the sliding shaft 405, thereby compressing the spring 406, and the citrus falls from the lower port of the main barrel. At this time, the infrared sensor 10 detects the fallen citrus, and the PLC controller 11 controls the push rod of the hydraulic cylinder 8b. The push rods of the hydraulic cylinders 8b of the two squeezing assemblies 8 are extended at the same time, thereby driving the two juice pressing plates 8c to move closer to each other, so that the citrus is squeezed. The juice flows out from the cutout on the outer skin of the citrus and is temporarily stored in the juice pressing bucket 5. The PLC controller 11 controls the electric telescopic rod 6c of the opening and closing assembly 6. The electric telescopic rod 6c push rod drives the door body 6a to move axially along the guide rod 6f to separate the two door bodies 6a. At this time, the discharge hole 5a is opened, and the PLC controller 11 controls the push rods of the hydraulic cylinders 8b of the two squeezing assemblies 8 to retract at the same time, thereby driving the two juice pressing plates 8c to move away from each other. The squeezed fruit and juice fall from the discharge hole 5a to the discharge hopper 7a of the solid-liquid separation assembly 7, and the squeezed fruit falls on the screen 7g. The juice continues to be discharged from the drain pipe 7e, and the squeezed fruit falling on the screen 7g can be blown away by the discharge pipe 7b under the blowing of the high-pressure fan 7c. The above actions are repeated to realize automatic juicing of the citrus.

[0052] The above is only a specific embodiment of the present invention, but the protection scope of the present invention is not limited thereto. Any person skilled in the art can easily think of changes or substitutions within the technical scope disclosed by the present invention, which should be included in the protection scope of the present invention. Therefore, the protection scope of the present invention should be based on the protection scope of the claims.
