[0019] like Figure 1-6As shown, the green soybean harvester includes a self-propelled power chassis 11, a harvesting and sorting box 7, and a header bracket 13. The harvesting and sorting box 7 is arranged on the self-propelled power chassis 11. The upper part of the harvesting and sorting box 7 is a picking area 5. The picking area 5 is provided with a picking conveying clamping chain 6. The front end of the self-propelled power chassis 11 is provided with a header bracket 2. The inner side of the bottom of the header bracket 2 is hinged to the self-propelled power chassis 11 through a hinge 10. The front side of the bottom is connected to the self-propelled power chassis 11 through an oil cylinder 12. Through the action of the oil cylinder 12, it can swing slightly around the hinge 10 to adjust the working height. The header bracket 2 is provided with a pulling conveying clamping chain 1 for the green soybean plant 1. 3. A No. 1 steering conveyor clamping chain 3 and a No. 2 steering conveyor clamping chain 8 are arranged between the pulling-up conveyor clamping chain 13 and the picking conveyor clamping chain 6. The green soybean plant 1 passes through the pulling-up conveyor clamping chain 13, the No. 1 steering conveyor clamping chain 3, the No. 2 steering conveyor clamping chain 8 and the picking conveyor clamping chain 6 in sequence. A side pressure spring pressure rod 14 is fitted at the front end of the No. 1 steering conveyor clamping chain 3, and an upper pressure spring pressure rod 15 is fitted at the rear end. An upper pressure spring pressure rod extension section 16 at the tail of the upper pressure spring pressure rod 15 extends from the No. 1 steering conveyor clamping chain 3 to the front end of the No. 2 steering conveyor clamping chain 8, and a spring pressure rod 17 is arranged on the No. 2 steering conveyor clamping chain 8.

[0020] The No. 1 steering conveying clamping chain 3 and the No. 2 steering conveying clamping chain 8 are connected by a connecting rod 9. When the cutting platform bracket 2 swings to a certain angle, the No. 2 steering conveying clamping chain 8 makes corresponding deflection under the traction of the connecting rod 9 to maintain the matching distance with the No. 1 steering conveying clamping chain 3 to ensure smooth transmission; the No. 2 steering conveying clamping chain 8 is connected to the inlet end of the picking conveying clamping chain 6 through the swing fulcrum shaft 4, and the end swing fulcrum shaft 4 of the No. 2 steering conveying clamping chain 8 is coaxial with the power shaft at the front end of the picking conveying clamping chain 6, and can deflect around the swing fulcrum shaft 4.

[0021] The front section of the No. 1 steering conveying clamping chain 3 is arranged below the last section of the pulling-up conveying clamping chain 13 , and the last section is arranged inside the front end of the No. 2 steering conveying clamping chain 8 .

[0022] The forward speed of the No. 2 steering conveying clamping chain 8 and the picking conveying clamping chain 6 is greater than the forward speed of the No. 1 steering conveying clamping chain 3 .

[0023] The No. 1 steering conveying clamping chain 3 is hinged by multiple sprockets 21, and the sprockets 21 include an upper tooth piece 18, a lower tooth piece 19, and a roller 20. The upper tooth piece 18 is an L-shaped tooth piece, one side is a triangular piece, and the other side is a mountain-shaped piece, which is integrally formed to form the upper tooth piece 18. The lower tooth piece 19 is a mountain-shaped piece, which is hinged to one side of the mountain-shaped piece of the upper tooth piece 18 through the roller 20. The triangular piece of the upper tooth piece 18 is arranged on the outside, and the side pressure spring pressure rod 14 is arranged between the mountain-shaped piece of the upper tooth piece 18 and the lower tooth piece 19. The upper pressure spring pressure rod 15 is arranged between the angle formed by the mountain-shaped piece and the triangular piece of the upper tooth piece 18.

[0024] When the device is used, the green soybean plant 1 grows vertically to the ground before harvesting, and is still vertical to the ground when it is pulled up and transported upward by the pulling conveying clamping chain 13. Continue to move forward in direction A and enter the No. 1 steering conveying clamping chain 3. During the forward movement of the soybean plant 1 on the No. 1 steering clamping chain 3, due to the special combined tooth shape of the No. 1 steering clamping chain 3 and the combined action of the upper pressure spring pressure rod 15 and the auxiliary pressure rod, the soybean plant changes from an approximately vertical state to an approximately horizontal state. Then, under the combined action of the No. 1 steering clamping chain 3 and the No. 2 steering conveying clamping chain 8, since the speed V2 of the No. 2 steering conveying clamping chain 8 is greater than the speed V1 of the No. 1 steering clamping chain 3, the soybean plant completes the horizontal angle change, and is sent to the picking area by the picking conveying clamping chain 6 in a state where the root is in front and the tip is in the back. After picking, the bean pods continue to be sent back to the field by the picking conveying clamping chain 6 along direction D.

[0025] When the device of the present invention is adopted, the roots of the green soybean plants enter first, which can avoid the bean pods from breaking branches to the greatest extent, improve the harvest rate and reduce the loss.
