DETAILED DESCRIPTION

[0021] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0022] Example 1: Reference Figure 1-Figure 12 The ear picking and separation device shown includes a harvester 1 and a header 2 mounted on the harvester 1, wherein the header 2 includes a plurality of harvesting modules, and the harvesting modules include a translation component 3, an oblique movement component 4 and a cutting component 5; The translation assembly 3 includes two translation units 31 and a translation driving unit 32. The translation unit 31 includes a translation chain 311 and a plurality of translation rods 312. The plurality of translation rods 312 are evenly fixedly mounted on the translation chain 311. The translation chain 311 can drive the translation rods 312 to move. The tilt assembly 4 includes a plurality of tilt units 41 and a tilt drive unit 42. The tilt unit 41 includes a tilt wheel 411. The tilt wheel 411 is tilted. The tilt drive unit 42 can drive the tilt wheels 411 in all the tilt units 41 to rotate. The harvesting module further includes a pressing assembly 6, which includes a pressing spring 61 and an adjusting unit 62. The pressing spring 61 can press the oblique shift wheel 411, and the adjusting unit 62 can adjust the elastic force of the pressing spring 61. The cutting assembly 5 can cut the straw.

[0023] The harvester 1 drives the header 2 to move, and the corn stalks enter between two adjacent harvesting modules. The translation components 3 in the two harvesting modules drive the corn stalks to move. The translation component 3 moves the corn stalks toward the oblique movement component 4, and the cutting component 5 cuts the corn stalks. The oblique movement wheels 411 in the two adjacent harvesting modules rotate to move the corn stalks obliquely downward. The corn stalks move toward the harvester 1 while moving downward. The cutting component 5 located below the oblique movement component 4 chops the corn stalks into pieces. The corn fruits on the corn stalks are too large to pass through the gap between the adjacent translation rods 312 and are separated from the corn stalks. The corn fruits are moved into the harvester 1 by the translation rod 312, and the compression spring 61 compresses the oblique movement wheels 411 in the two harvesting modules. The compression force of the oblique movement wheels 411 in the two harvesting modules is adjusted by the adjustment unit 62.

[0024] The corn stalks are compacted by the oblique wheel 411, and are driven to move obliquely downward, and the corn stalks are moved horizontally and downward at the same time, so that the corn stalks are chopped by the cutting assembly 5 below, and the corn kernels are blocked by the translation rod 312 and separated from the corn stalks, so that the corn stalks and corn kernels can be continuously separated and processed separately, thereby improving the processing capacity. The oblique wheel 411 has a better compacting effect on the corn stalks to prevent the corn stalks from slipping, and the compacting wheel that can adjust the oblique wheel 411 ensures that the corn stalks with inconsistent thickness due to different growth conditions have a better compacting force, and the compacting spring 61 is used to make the oblique wheel 411 have a certain horizontal movement amount, thereby ensuring that the compacting force on the corn stalks is moderate, preventing the corn stalks from being broken and the corn stalks from being continuously driven downward.

[0025] The translation rods 312 in the two translation units 31 limit the corn stalks to prevent the corn stalks from tilting, ensuring that the oblique wheels 411 continuously drive the corn stalks to move downward, and also ensuring the cutting effect of the cutting assembly 5 on the corn stalks.

[0027] When the rotating shaft 413 rotates, the rotating shaft 413 drives the rotating driving pulley to rotate, the rotating driving pulley drives the rotating driven pulley to rotate, and the rotating driven pulley causes the oblique shift wheel 411 to rotate.

[0028] Example 3, reference Figure 1-Figure 12 , which is different from the above-mentioned embodiment, the oblique shift assembly 4 also includes a plurality of linkage belt members 7, and the plurality of linkage belt members 7 are respectively arranged on two adjacent rotating shafts 413, and the linkage belt members 7 include two linkage pulleys and a linkage belt, and the two linkage pulleys are respectively fixedly installed on the two adjacent rotating shafts 413, and the linkage belt is connected to the two linkage pulleys.

[0029] When one rotating shaft 413 rotates, the rotating shaft 413 drives the corresponding linkage pulley to rotate, and the linkage pulley rotates another linkage pulley through the linkage belt, and the other linkage pulley drives the corresponding oblique shift wheel 411 to rotate, thereby driving all the oblique shift wheels 411 to rotate.

[0033] The clamping spring 61 clamps the skew wheel 411. When the skew wheel 411 and the driving shell 421 move, the driving shell 421 drives the stabilizing bar 65 to move in the stabilizing groove, making the driving shell 421 and the skew wheel 411 more stable and less likely to shake. At the same time, the driving shell 421 moves in the clamping shell 66 to ensure that no impurities enter the clamping shell 66.
