After the fruits and vegetables output by the fruit feeding mechanism 5 are introduced into the fruit groove, the fruits and vegetables are spread out in a single layer in the fruit groove along the axis of the fruit rack 44, and the fruits and vegetables will not be squeezed by each other, so as to prevent the fruits and vegetables from being crushed; when one of the fruit racks 44 is full of fruits and vegetables, the first driving mechanism 43 drives the turntable 42 to rotate, so that the other fruit rack 44 is close to the output end of the fruit feeding mechanism 5, and continues to receive the fruits and vegetables output from the fruit feeding mechanism 5; the principle of the cache mechanism 4 is similar to that of a Ferris wheel, and when the turntable 42 rotates, the opening of the fruit groove is always upward; when the cache mechanism 4 needs to output fruits and vegetables, the flipping part drives one of the fruit racks 44, and after the fruit rack 44 rotates, the notch of the fruit groove tilts downward, so that the fruits and vegetables therein fall into the fruit delivery mechanism 6, so that the fruit delivery mechanism 6 can transport the fruits and vegetables to the net mechanism 8. Among them, the flipping part can be in the form of a rotating cylinder, etc., which can be adopted according to actual needs.

[0053] As an implementation method, the fruit racks 44 are arranged in sequence along the circumference of the turntable 42; the fruit feeding mechanism 5 includes: a fruit feeding barrel 51, a feeding mechanism (not shown in the figure) and a second driving mechanism 53; a accommodating space 511 for accommodating fruits and vegetables is formed in the fruit feeding barrel 51, and a fruit outlet 512 connected to the accommodating space 511 is provided on the upper side of the fruit feeding barrel 51, and the fruit feeding barrel 51 is arranged parallel to the inner side of the fruit rack 44; the feeding mechanism is installed on the frame 41, and the feeding mechanism can guide the fruits and vegetables of the picker into the fruit feeding barrel 51 through the fruit outlet 512; the second driving mechanism 53 is installed on the frame 41, and the second driving mechanism 53 can drive the fruit feeding barrel 51 to rotate, so as to pour the fruits and vegetables in the fruit feeding barrel 51 through the fruit outlet 512 onto one of the fruit racks 44.

[0054] As an implementation method, an avoidance hole 421 is provided at the center of one of the turntables 42, and one end of the fruit feeding barrel 51 passes through the avoidance hole 421 to extend to the outside of the turntable 42; the accommodating space 511 includes a fruit receiving part 5111 located on the outside of the turntable 42, and a fruit output part 5112 located between the two turntables 42; the feeding mechanism is arranged on the outside of the turntable 42 to deliver the fruits and vegetables output by the picking machine into the fruit receiving part 5111; the fruit feeding mechanism 5 also includes: a push plate 54, a push rod 55 and a third driving mechanism 56; the push plate 54 is arranged in the fruit receiving part 5111; one end of the push rod 55 is connected to the push plate 54, and the other end of the push rod 55 is facing away from the fruit output part 5112 and extends to the outside of the fruit feeding barrel 51; the third driving mechanism 56 is installed on the frame 41, and can drive the push plate 54 through the push rod 55 to push the fruits and vegetables in the fruit receiving part 5111 into the fruit output part 5112.

[0055] Through the above arrangement, it is convenient for the feeding mechanism to transport fruits and vegetables from the outside to the inside of the buffer mechanism 4, and it is convenient to install the feeding mechanism.

[0056] In the present application, the length of the fruit outlet portion 5112 is substantially the same as the length of the fruit rack 44. After the fruits and vegetables in the fruit outlet portion 5112 are poured into the fruit rack 44, the entire fruit rack 44 can be substantially filled, thereby improving the utilization rate of the fruit rack 44. The feeding mechanism can be in the form of a conveyor belt or an auger roller to transport the fruits and vegetables picked by the picking machine into the fruit receiving portion 5111 of the fruit feeding barrel 51. The third driving mechanism 56 drives the push plate 54, and the push plate 54 pushes the fruits and vegetables into the fruit outlet portion 5112. The sensor is used to count the number of fruits and vegetables entering the fruit feeding barrel 51. When the fruit outlet 5112 is basically full of fruits and vegetables, the second driving mechanism 53 drives the fruit feeding barrel 51 to rotate, and the fruit outlet 512 of the fruit feeding barrel 51 is downward. After the fruits and vegetables in the fruit outlet 5112 are poured onto the fruit rack 44 below, the second driving mechanism 53 drives the fruit feeding barrel 51 to rotate in the opposite direction and reset. The first driving mechanism 43 drives the turntable 42 to rotate, so that another empty fruit rack 44 moves to the bottom of the fruit feeding barrel 51 to prepare for the next round of fruit feeding.

[0057] As an implementation method, the fruit feeding mechanism 5 also includes a stopper 57, which is installed in the fruit feeding tube 51 and arranged between the fruit receiving portion 5111 and the fruit output portion 5112. Fruits and vegetables can roll through the upper side of the stopper 57 to the fruit output portion 5112 under the action of the push plate 54.

[0058] Through the above arrangement, the fruits and vegetables entering the fruit output portion 5112 can be prevented from rolling back into the fruit output portion 5112 .

[0059] It should be understood that those skilled in the art can make improvements or changes based on the above description, and all these improvements and changes should fall within the scope of protection of the claims attached to the utility model.
