Detailed implementation manners

[0043] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present invention without creative efforts shall fall within the protection scope of the present invention.

[0044] Embodiment 1: Refer to Figures 1-12 A kind of ear picking and separating device shown, including a harvester 1 and a cutting table 2 installed on the harvester 1. The cutting table 2 includes a plurality of harvesting modules. The harvesting module includes a translation assembly 3, an oblique shifting assembly 4 and a cutting assembly 5;

[0045] The translation component 3 includes two translation units 31 and a translation drive unit 32. The translation unit 31 includes a translation chain 311 and a number of translation rods 312. The number of translation rods 312 are evenly and fixedly installed on the translation chain 311, and the translation chain 311 can drive the translation rods 312 to move;

[0046] The inclined translation component 4 includes a number of inclined translation units 41 and an inclined translation drive unit 42. The inclined translation unit 41 includes an inclined translation wheel 411. The inclined translation wheel 411 is inclined. The inclined translation drive unit 42 can drive the inclined translation wheels 411 in all the inclined translation units 41 to rotate;

[0047] The harvesting module further includes a pressing component 6. The pressing component 6 includes a pressing spring 61 and an adjustment unit 62. The pressing spring 61 can press the inclined translation wheels 411, and the adjustment unit 62 can adjust the elastic force of the pressing spring 61;

[0048] The cutting component 5 can cut off the straw.

[0049] The harvester 1 drives the cutting table 2 to move. The corn straw enters between two adjacent harvesting modules. The translation components 3 in the two harvesting modules drive the corn straw to move. The translation component 3 moves the corn straw in the direction of the inclined translation component 4. The cutting component 5 cuts off the corn straw. The inclined translation wheels 411 in two adjacent harvesting modules rotate to move the corn straw obliquely downward. The corn straw moves toward the harvester 1 while moving downward. The cutting component 5 located below the inclined translation component 4 cuts the corn straw into pieces. The corn fruits on the corn straw are too large in volume to pass through the gaps between the adjacent translation rods 312 and are separated from the corn straw. The corn fruits are moved by the translation rods 312 into the harvester 1. The pressing spring 61 presses the inclined translation wheels 411 in the two harvesting modules, and the pressing force of the inclined translation wheels 411 in the two harvesting modules is adjusted through the adjustment unit 62.

[0050] The corn straw is pressed by the inclined translation wheels 411 and is driven by the inclined translation wheels 411 to move obliquely downward, moving horizontally and downward at the same time, so that the cutting component 5 below cuts the corn straw into pieces. The corn fruits are blocked by the translation rods 312 and separated from the corn straw. The corn straw and the corn fruits can be continuously separated and processed separately, improving the processing capacity. The pressing effect of the inclined translation wheels 411 on the corn straw is better, preventing the corn straw from slipping. And the pressing wheels of the inclined translation wheels 411 can be adjusted to ensure good pressing force on corn straws with different thicknesses caused by different growth conditions. And through the pressing spring 61, the inclined translation wheels 411 have a certain amount of horizontal movement, ensuring that the pressing force on the corn straw is moderate and preventing the corn straw from being crushed and unable to continuously drive the corn straw to move downward.

[0051] The translation rods 312 in the two sets of translation units 31 limit the corn straws, preventing the corn straws from tilting, ensuring that the inclined translation wheels 411 continuously drive the corn straws to move downward, and also ensuring the cutting effect of the cutting assembly 5 on the corn straws.

[0052] Example 2. Refer to Figures 1-12 , which is different from the above example in that the inclined translation unit 41 further includes a support block 412, a rotating shaft 413, a rotating belt member 414, and a belt protective shell 415.

The rotating driving belt pulley is fixedly installed on the rotating shaft 413, the rotating driven belt pulley is fixedly installed on the inclined translation wheel 411, and the rotating belt is connected between the rotating driving belt pulley and the rotating driven belt pulley.

[0053] When the rotating shaft 413 rotates, the rotating shaft 413 drives the rotating driving belt pulley to rotate. The rotating driving belt pulley drives the rotating driven belt pulley to rotate, and the rotating driven belt pulley makes the inclined translation wheel 411 rotate.

[0054] Example 3. Refer to Figures 1-12 , which is different from the above example in that the inclined translation assembly 4 further includes a plurality of linkage belt members 7.

The two linkage belt pulleys are respectively fixedly installed on two adjacent rotating shafts 413, and the linkage belt is connected between the two linkage belt pulleys.

[0055] When one rotating shaft 413 rotates, this rotating shaft 413 drives the corresponding linkage belt pulley to rotate. This linkage belt pulley makes another linkage belt pulley rotate through the linkage belt, and the another linkage belt pulley drives the corresponding inclined translation wheel 411 to rotate, thereby driving all the inclined translation wheels 411 to rotate.

[0059] The pressing spring 61 presses the inclined shift wheel 411. When the inclined shift wheel 411 and the drive housing 421 move, the drive housing 421 drives the stabilizing strip 65 to move in the stabilizing groove, making the drive housing 421 and the inclined shift wheel 411 more stable and not prone to shaking.
