However, during this series of separations, a large amount of crushed corn kernels would be mixed with corn silk, corn cobs, corn leaves and their debris and could not be separated.

[0066] The cross section of the elastic key 11 is T-shaped; A spring or an electromagnetic part or an air bag is arranged between the step surface of the elastic key 11 and the inner wall of the fastening cone set 8; The inclination angle of the oblique end portion is 45 degrees.

[0067] At the stirring station 15, the rotary manipulator 14 rotates, and the rotary manipulator 14 simultaneously realizes rotation and revolution in the circular box, so that the finger part 31 rotates and wraps the corn silk or corn leaf; Then, the rotary manipulator 14 rotates with the axis of the oblique end of the oblique base 13 as a reference, so that the conical shaft portion 32 swings from the vertical state of the stirring station 15 to the horizontal state of the replacement station 16; Secondly, at the replacement station 16, the robot arm of the cleaning frame assembly 12 is extended or the rotating spindle assembly 4 is extended, so that the cone sleeve 8 enters the front section of the hollow inner hole 33 of the hand cone sleeve portion 30 and is tightened; Again, the mechanical arm of the cleaning rack assembly 12 is retracted or withdrawn, and the cone sleeve 8 with the hand cone sleeve portion 30 is separated from the rotating cone shaft portion 32; Afterwards, the rotating spindle assembly 4 is rotated by a set angle so that the cleaned cone sleeve 8 faces the rotating cone shaft portion 32; Then, the mechanical arm of the cleaning frame assembly 12 is extended or the rotating spindle assembly 4 is extended, so that the rotating cone shaft portion 32 enters the rear section of the hollow inner hole 33 of the hand cone sleeve portion 30 and is tightened; Afterwards, the elastic key 11 is separated from the inner wall of the hollow inner hole 33 of the hand cone sleeve 30 by pressure, and the replacement is completed.

The carrier storage component 1 realizes the rapid collection and centralized cleaning of the winding long and thin fibers, and the cleaning does not affect the normal work. The cleaning component 2 realizes the winding by rotation and revolution. However, the existing method of rotation and revolution structure, the prior art does not propose a solution and technical inspiration to solve the long and thin soft debris such as long and thin corn silk.

[0069] The present invention uses a conventional structure for the carrier base 3, a rotating spindle assembly 4 to realize rotation, and a carrier rotating disk 5 to realize the installation of a carrier clamp 6, so as to facilitate the replacement of the taper sleeve. The elastic key 11 is elastically movable through the tapered shaft portion 7, the taper sleeve 8, the front top nut head 9, and the lateral through slot 10, so as to realize the clamping of the taper friction force.

[0070] The present invention adopts a conventional structure by cleaning the frame group 12, and realizes driving the hand cone sleeve part 30 to rotate through the inclined base 13 and the rotating manipulator 14, and realizes winding through the finger part 31. The rotating cone shaft part 32 is preferably a taper, and the hollow inner hole 33 is preferably a double taper, that is, the rear section cooperates with the rotating cone shaft part 32, and the front section cooperates with the head 9 laterally. By rotating 45 degrees, the movement of the stirring station 15 and the replacement station 16 is realized, and components such as motors and bolts are omitted.

[0072] In order to realize neutral gear, low speed gear and high speed gear through the fork frame 22, the fork arm 23 and the sliding gear set 24, the fingers can rotate and revolve, so as to complete the winding of the hair according to the adjustment. If the self-rotation winding speed does not match the revolution winding speed, the revolution speed is too fast, and effective winding cannot be achieved, and the cleaning is not clean, and it is impossible to use the long hair to carry the winding of the short hair. If the revolution speed is too slow, the efficiency is low. The present invention realizes effective rotation through three gears, and each indexing motor is preferentially rotated synchronously. In order to achieve synchronization, synchronization can be coordinated with a frequency converter. Of course, three synchronizations can be achieved through chain transmission.

[0073] The first gear shaft A25, the first shifting tooth A26, the second gear shaft B27, the second shifting tooth B28, and the third gear shaft C29 cooperate with each other, and the shifting tooth structure is used to realize the decelerated rotation. The hand cone sleeve part 30 adopts a replacement setting, and winding is realized by the finger part 31. The support installation is realized by rotating the cone shaft part 32. The storage disk 34 integrates a funnel function, and the water tank part 35 is used to separate stones and bad corn kernels. The soaked corn kernels are output through the vibration output part 36. The inclined vibration part 37 realizes the screening of small particles and debris. At the same time, the waste box 39 and the sundry material box 42 are used to collect waste through accessories such as the blowing component 38. The guide plate 40 realizes the guiding setting, which is preferably inclined at 45 degrees. The vibrating screen conveyor belt 41 is vibrated by the cam to make the corn seeds fall and guide A conventional guide channel is installed on the frame 43 to realize the falling of corn seeds, and multi-stage output is realized through the collecting conveyor belt 44. The corn seeds are cleaned in the temporary storage box 45, which has built-in supporting components such as a stirring paddle or a water pump. The collecting conveyor belt 46 realizes the output of corn seeds 47, which is air-dried and can be equipped with side supports and cross baffles. Ventilation and water leakage are realized through mesh holes. The screened corn mixture is stored through the storage shell 48. The inner conical bottom 49 realizes the concentration of corn seeds, which is convenient for stirring and falling. The central falling channel 50 realizes the falling of corn seeds, the falling guide channel 52, and the flip conical baffle 51 use the conical surface to realize the falling of corn seeds. The blowing nozzle 53 realizes the blowing of debris upwards, and the upper part thereof can be equipped with a suction part, thereby realizing the collection of floating debris.
