[0068] The motor 12 is fixedly mounted on the top of the threaded rod 15. Two first electric slide rails 5 are provided. The first electric slide rails 5 form a lifting structure through the limit sleeve 33, the threaded rod 15 and the motor 12. The limit sleeve 33 outside the threaded rod 15 can be threadedly moved up and down and rotated through the interaction between the motor 12 and the threaded rod 15, so that the corn cobs can be flexibly adjusted and picked according to the height of the corn cobs.

[0083] The connecting shaft 24 is movably connected to the inside of the fixed side plate 23 ; the guide plate 22 is movably connected to the middle part of the outside of the connecting shaft 24 .

[0084] In summary, when the corn ear picking device is used, firstly Figure 1-Figure 6The structure shown in the figure, firstly, through the interaction between the motor 12 and the threaded rod 15, the limit sleeve 33 outside the threaded rod 15 can be threadedly moved up and down and rotated, so that it can be flexibly adjusted and picked according to the height of the corn cob. At the same time, the design of the rotating structure can perform a wider range of picking processing according to the planting range of the corn cob. It is flexible to use, and the interaction between the first electric slide rail 5 and the first slider 6 can be used to drive the manipulator 10 to move left and right, which can increase the picking range of the corn cob. At the same time, the design of the servo motor inside the motor outer frame 8 can be used to drive the manipulator 10 to rotate quickly, so that the corn stalks rooted in the ground can be pulled out. The manipulator 10 is height-adjustable and can pick the corn cobs and pull out the corn cob stalks, eliminating the step of the working people cutting the corn stalks in the ground. Then, the picked corn cobs will be placed on the conveyor When the outer surface of the belt 16 is transported to a certain position by the conveyor belt 16, the user can place the placement plate 20 inside the second slide 27 in advance, and can selectively control the transfer direction of the placement plate 20 according to the use, that is, the interaction of the limit frame 25, the block 26, the second slide 27, the second slider 31, the electric push rod 32 and the second electric slide 30 can be used to control the up and down movement range and horizontal movement direction of the block 26, thereby realizing the movement of the position of the placement plate 20. The specific operation of the placement plate 20 is that it is integrally connected to the end of the electric push rod 32. The user can place the placement plate 20 inside the second slide 27 in advance, and can move the placement plate 20 placed in the second slide 27 in advance to a horizontal position through the cooperation of the electric push rod 32, the second electric slide 30, the second slide 27 and the second slider 32. The placement plate 20 is conveniently located at the end of the left conveyor belt 16 or the end of the right conveyor belt 16, so that the corn ears in the conveyor belt 16 can be collected in the placement plate 20, which is convenient for the trial pack to uniformly collect the corn ears in the placement plate 20 without waiting for the conveyor belt 16 to collect the corn ears individually. In summary, the placement plate 20 receives and collects the corn ears in the two groups of conveyor belts 16, avoiding the user from intermittently collecting the corn ears in the conveyor belt 16, and then the placement plate 20 will be placed outside the end of the conveyor belt 16 according to the movement needs, and then a mechanical auxiliary gripper is provided outside the end of the pushing mechanism 18, so that when the corn ears after picking are placed on the conveyor belt 16 for transmission, when they are transmitted to a certain position, the corn ears will fall onto the surface of the placement plate 20 placed in advance, and the design of the mechanical auxiliary gripper can be used to synchronously cooperate with the interaction of the hydraulic rod 28 at the rear end of the pushing mechanism 18 to move back and forth, so as to facilitate the unified storage and re-transmission of the corn ears, which brings convenience to the collection of subsequent users;

[0085] Finally, through the design of the protective plate 9, when the ear picking device is not needed, the user can manually limit the protective plate 9 to the inside of the connecting bottom frame 11, so that the ear picking device can be shielded and protected from the front and back sides. At the same time, it is also convenient to subsequently store the manipulator 10 between the two protective plates 9, which has a certain hiding effect.
