Specific implementation

[0019] As Figures 1-5 The residual film picking mechanism includes the rolling roller 1, the guide roller 2 and the demoulding roller 3 sequentially rotatingly installed on the frame of the residual film picking machine from bottom to top, the axes of the rolling roller 1, the guide roller 2 and the demoulding roller 3 are arranged in parallel, and the three are driven to rotate by the power equipment installed on the frame of the residual film picking machine, the power equipment can be a motor, a hydraulic motor or a power output end of a traction tractor, the power transmission mode is the same as that of the prior art residual film picking machine, and the specification will not be repeated here.

[0020] Four groups of long nail tooth belts 4 are arranged on the rolling roller 1, the guide roller 2 and the demoulding roller 3 in common along the axial direction, and the four groups of long nail tooth belts 4 correspond to the mulch film of the film-laying planting crop edge film part and the film of the wheel rolling part of the crop harvesting machinery (such as a cotton picker).

[0021] A plurality of long nail teeth 6 are fixedly installed on the outer side of the long nail tooth belt 4 at uniform intervals, a plurality of short nail teeth 7 are fixedly installed on the outer side of the short nail tooth belt 5 at uniform intervals, and the length of the long nail tooth 6 is greater than the length of the short nail tooth 7.

[0022] The roller 1 is a smooth roller structure, which is used to press the long nails 6 on the long nail belt 4 and the short nails 7 on the short nail belt 5 into the soil and lift the mulch on the ground. In this process, the long nails are pressed into the edge row and the vehicle roller position of the harvesting machine, and the mulch in the lower position is lifted, while the short nails are pressed into the other ground and the corresponding position of the mulch is lifted. Then the lifted mulch moves with the long nail belt 4 and the short nail belt 5 to the position of the guide roller 2.

[0023] The guide roller 2 includes a guide roller shaft 2-1, and large guide wheels 2-2 are arranged on both sides of each long nail belt 4, and small guide wheels 2-3 are arranged on both sides of each short nail belt 5. The wheel groove for accommodating the long nail belt 4 is formed between the two adjacent large guide wheels, and the wheel groove for accommodating the short nail belt 5 is formed between the two adjacent small guide wheels and the adjacent small guide wheel and large guide wheel, so as to prevent the left and right sliding of each nail belt. The distance between the outer wall of the large guide wheel and the outer surface of the long nail belt on the guide roller shaft is less than the length of the long nail, and the distance between the outer wall of the small guide wheel and the outer surface of the short nail belt on the guide roller shaft is less than the length of the short nail, so that the end of the long nail and the short nail is outside the corresponding large guide wheel or small guide wheel. When the residual film passes through the guide roller 2, on the one hand, the residual film is pushed to the end of the nail by the large guide wheel and the small guide wheel of the guide roller 2, and on the other hand, it can also ensure that the residual film does not deviate from the corresponding nail, and the broken straw or other impurities near the end of the nail tip are removed, and then the residual film moves with the long nail belt and the short nail belt to the direction of the demoulding roller.

[0024] The demoulding roller 3 includes a demoulding roller shaft 3-1, and large demoulding wheels 3-2 are arranged on both sides of each long nail belt 4, and small demoulding wheels 3-3 are arranged on both sides of each short nail belt 5. The wheel groove for accommodating the long nail belt 4 is formed between the two adjacent large demoulding wheels 3-2, and the wheel groove for accommodating the short nail belt 5 is formed between the two adjacent small demoulding wheels and the adjacent small demoulding wheel and large demoulding wheel. The distance between the outer wall of the large demoulding wheel 3-2 and the outer surface of the long nail belt 4 on the demoulding roller shaft 3-1 is more than 10mm than the length of the long nail 6, and the distance between the outer wall of the small demoulding wheel 3-3 and the outer surface of the short nail belt 5 on the demoulding roller shaft 3-1 is more than 10mm than the length of the short nail 7. When the residual film runs to the demoulding roller 3 with the nail belt, each long nail completely enters the wheel groove between the two adjacent large demoulding wheels 3-2, and each short nail completely enters the wheel groove between the two adjacent small demoulding wheels and the adjacent small demoulding wheel and large demoulding wheel, so that the mulch on each position of the nail is completely separated from the nail by the demoulding wheel, and the automatic demoulding operation is completed.
