DETAILED DESCRIPTION OF THE EMBODIMENTS

[0023] As Figures 1-3 shown, the secondary picking component of the corn cobs in this embodiment includes a falling frame 41 with an opening at the middle bottom; thus, the corn cobs are concentrated and fall to gather.

[0024] The opening of the falling frame 41 is hinged with an inclined mating baffle 43; when the inclined mating baffle 43 is mated, a V-shaped structure is formed; it can realize self-positioning of corn ears when opening and at the same time, prevent debris from accumulating in the frame and can be output one by one.

[0025] An intermediate roller 44 with a convex top is disposed transversely in the middle below the inclined abutment baffle 43; the middle roller 44 can be circular, triangular prism or other shapes by utilizing the different positions of the midpoint and the center of gravity to achieve ingenious automatic sorting.

[0026] A first drop channel 45 and a second drop channel 46 are respectively arranged on the left and right sides of the middle roller 44, so as to achieve separation output. The cross-shaped structure is cleverly utilized.

[0027] A turning device 47 is provided at the obliquely lower exits of the first drop channel 45 and the second drop channel 46, so as to realize automatic separation.

[0028] A V-shaped centering gripper 42 is provided above the falling frame 41 , and the V-shaped centering gripper 42 is used to longitudinally move the falling corn ear so that the center of the corn ear is aligned with the middle roller 44 .

[0029] Guide inclined plates 48 are respectively provided at the first falling channel 45 and the second falling channel 46 for guiding the corn ears falling obliquely downward to the corresponding turning devices 47 .

[0030] The turning device 47 includes a fixedly arranged articulated bracket 49 to realize fixed support; a swing bracket 50 is hingedly connected to the articulated bracket 49, and its pitch structure is utilized to realize automatic adjustment and unified output;

[0031] As a specific description, a receiving station 51 is provided at the lower exit of the guide inclined plate 48; a dropping station 52 is provided below the receiving station 51;

[0032] When unloaded, the inlet and outlet of the swing bracket 50 face upwards and correspond to the receiving station 51;

[0033] When unloaded, the inlet and outlet of the swing bracket 50 face upwards and correspond to the receiving station 51; the center of gravity of the swing bracket 50 is located on the side of the hinged bracket 49 away from the receiving station 51;

[0034] When loading objects, the entrance and exit of the swing bracket 50 swing downward to correspond to the falling station 52 .

[0035] When loading, the inlet and outlet of the swing bracket 50 swing downward to correspond to the falling station 52; the center of gravity of the corn ear and the center of gravity of the swing bracket 50 are located on the side of the hinged bracket 49 close to the receiving station 51.

[0036] The present invention realizes ingenious output drop.

[0037] As an improvement, an elastic guide plate 56 is provided on the inner side wall of the guiding inclined plate 48 for laterally positioning the falling corn ears, so as to facilitate correct falling onto the swinging bracket 50. Of course, a V-shaped channel or a matching funnel can also be used. However, by tilting, two component velocities, one downward and one horizontal, are given to the corn ears, so that the corn ears fall obliquely onto the swinging bracket 50.

[0038] The swinging bracket 50 has an upper opening 57 for receiving the falling corn ears, so as to facilitate better receiving of the corn ears.

[0039] An auxiliary ejecting rod 58 driven by a push rod is provided at the bottom of the swinging bracket 50 to assist in ejecting the corn ears.

[0040] An elastic limit block 59 is provided on the hinge bracket 49 for contacting the swinging bracket 50. It can be a spring or rubber, etc., to reduce noise and generate vibration at the same time, so that the corn ears fall better.

[0041] A return spring 60 is provided between the hinge bracket 49 and the swinging bracket 50 to play a buffering role.

[0042] A spring drive rod 63 is connected between the falling frame 41 and the inclined mating baffle 43. When the corn ears fall, the baffle is slightly opened and closed through the spring part, so as to facilitate the better lying flat of the inclined corn ears. It can be composed of a section of rod plus a section of spring.

[0043] During use, the premise is that the center of gravity of the corn ear is close to the large end of the root relative to the center of the corn ear.

[0044] First, the corn ears fall into the falling frame 41 and lie flat in the inclined mating baffle 43 by their own weight. The inclined mating baffle 43 oscillates through the spring drive rod 63 to adjust the position of the corn ears. Then, the V-shaped centering clamp 42 is driven to clamp both ends of the corn ears for centering, so that the length center of the corn ear is directly above the protrusion of the middle roller 44. Secondly, the inclined mating baffle 43 is opened through the spring drive rod 63, so that the middle part of the falling corn ear contacts the protrusion of the middle roller 44. Under the action of its own weight, the large end of the corn ear sinks and is in the first falling channel 45 or the second falling channel 46, and falls along the guiding inclined plate 48 to the receiving station 51, falls into the swinging bracket 50 from the upper opening 57 and swings down to the falling station 52. Thirdly, the corn ear slides downward with the large end facing up to leave, so as to realize the unified vertical output of the large and small ends of the corn ear.

[0045] In the present invention, the falling frame 41 is used to carry and make the corn ear lie flat, the V-shaped centering gripper 42 is used to adjust the position of the corn ear so as to achieve centering, the inclined alignment baffle 43 is used to achieve positioning and control of falling and opening / closing. The middle roller 44 is used for sorting and selection, the first falling channel 45 and the second falling channel 46 are used to achieve separation according to different center of gravity, the turning device 47 is used to make the corn ears uniformly arranged with the large end upward and the small end downward, the guiding inclined plate 48 is used to assist in lifting and generate an oblique speed so that the corn ears maintain an oblique state, the hinged bracket 49 is used for support, the swinging bracket 50 is swingably arranged, the receiving station 51 and the falling station 52 are used for input and output of the corn ears, the elastic guiding plate 56 is used for positioning assistance, the upper opening 57 enables the corn ears to fall quickly, the auxiliary pushing rod 58 is used to assist in pushing the corn ears, the elastic limiting block 59 and the return spring 60 are used to generate vibration for better output, and the spring driving rod 63 is used to generate vibration to facilitate the adjustment of the position of the corn ears.
