In the process of rotating the rotating rod 61, under the action of gravity, the opening above the placing box 64 always keeps upward, in the process of keeping the opening above the placing box 64 upward, the round rod 63 is driven to rotate, and the placing box 64 rotates around the round rod 63, in the process of rotating the placing box 64, the rubber gear 610 is driven to rotate along with the round rod 63, because the arc toothed plate 67 keeps motionless, in the process of rotating the rubber gear 610, the meshing effect of the arc toothed plate 67 drives the rubber gear 610 to rotate, thereby driving the connecting rod 69 to rotate, in the process of rotating the rubber gear 610, the round gear 612 meshed with the rubber gear 610 is driven to rotate along with the round rod 611, in the process of rotating the round gear 612, the first worm 613 rotates along with the round rod 613, thereby driving the first worm 615 meshed with the first worm 613 to rotate along with the round rod 614, in the process of rotating the screw lead screw 614, the worm wheel 616 connected on the wall of the screw rod is driven to move along with the screw rod 614, thereby the position of the worm gear 616 is driven to move along with the round rod 617, and the position of the round rod 617 is kept in contact with the fruit and vegetable plate 66 is continuously in the opposite direction, and the rotating direction of the reciprocating rod 617 is changed, and the position of the rotating along with the sliding rod 66 is continuously, and the rotating along with the rotating rod is continuously in the rotating direction of the rotating along with the reciprocating rod 66, the fruits and vegetables above are continuously changed to the position contacted with the supporting slide bar 66, so that the fruits and vegetables can be uniformly cooled to the greatest extent in the quick-freezing process, partial situations of incomplete quick-freezing or excessive quick-freezing of the fruits and vegetables are avoided, the quality and the taste of the fruits and vegetables can be kept, in the quick-freezing process, the moisture on the surfaces of the fruits and vegetables can be gradually frozen, the adhesion between the fruits and vegetables or between the fruits and vegetables and the surface of the supporting slide bar 66 can be prevented through slight vibration of the fruits and vegetables, each fruit and vegetable can be independently quick-frozen and cannot be adhered together, the fruits and vegetables can be stored one by one after quick-freezing, and the quick-freezing efficiency and the use effect of the equipment are improved;
In the quick freezing process of the quick freezing box 1, at this time, the transmission rod 72 drives the supporting rod 82 to rotate along with the transmission of the transmission belt 83 in the continuous rotating process, the second worm 87 is driven to rotate along with the rotation of the supporting rod 82, so that the second worm wheel 86 meshed with the second worm 87 rotates along with the rotation of the second worm wheel 86, the reciprocating screw rod 84 is driven to rotate along with the rotation of the reciprocating screw rod 84 under the limiting effect of the guide rod 88, the moving plate 616 can reciprocate on the rod wall of the reciprocating screw rod 84 along with the rotation of the reciprocating screw rod 84, the transmission toothed plate 814 is driven to move in the reciprocating movement process of the moving plate 616, so as to drive the winding rod 812 to rotate, the stay wire 816 is continuously wound on the rod wall of the winding rod 812 in the rotating process of the winding rod 812, so that the sealing piston 815 is pulled to move towards one end of the winding rod 812, and in the moving process of the sealing piston 815, because the check valve 818 arranged at the air outlet pipe 811 can not intake air, at the moment, the outside air can be pumped into the sealing shell 89 through the air inlet pipe 810 along with the movement of the sealing piston 815, and when the transmission toothed plate 814 moves towards the other end, the stay wire 816 wound on the rod wall of the winding rod 812 can be continuously moved out, at the moment, the moving piston can be pulled towards one end of the air outlet pipe 811 under the elastic force of the return spring 817, because the check valve 818 arranged at the air inlet pipe 810 can not exhaust air, at the moment, the air in the sealing shell 89 can be conveyed into the quick-freezing box 1 through the air outlet pipe 811, thereby improving the air circulation in quick-freezing equipment, promoting the evaporation of moisture on the surfaces of fruits and vegetables, helping to prevent the moisture on the surfaces of fruits and vegetables from being trapped, reducing the frost formed in the quick-freezing process, improving the quick-freezing effect and uniformity of the equipment, and the outside air contains rich oxygen, the oxygen content in the quick freezing equipment can be increased by injecting external air, so that the oxidization reaction of fruits and vegetables can be slowed down, and the color and nutrition of the fruits and vegetables can be maintained.
The foregoing is only a preferred embodiment of the present invention, but the scope of the present invention is not limited thereto, and any person skilled in the art, who is within the scope of the present invention, should make equivalent substitutions or modifications according to the technical scheme of the present invention and the inventive concept thereof, and should be covered by the scope of the present invention.
