Intelligent apparatus for separating walnut kernels and red coats by belt conveying and heat radiation based on thermal expansion and contraction principle

A continuous feeding mechanism, which is adapted to receive and transfer objects from a source to a designated conveying device, the continuous feeding mechanism comprising:

• a rotatable pulley, which has an external circumferential surface in which a plurality of grooves are formed, the plurality of grooves having openings formed in the external circumferential surface, such that rotation of the rotatable pulley brings the openings of the plurality of grooves to sequentially receive the objects from the source;
• a plurality of pushing pins, which are respectively and movably received in the plurality of grooves, each of the plurality of pushing pins being connected to and supported by a spring to be set at a home position;
• and
• a slide block, which is arranged at a working position relative to the rotatable pulley, such that the rotation of the rotatable pulley causes the plurality of pushing pins to sequentially approach and get in contact with the slide block at the working position, wherein the contact of the slide block with each pushing pin of the plurality of pushing pins causes a movement of said each pushing pin in the respective groove from the home position to a dump position, where the object received in the respective groove of said each pushing pin is forced out of the respective groove by the movement of the pushing pin.
