The labor intensity in the manual tray inserting process is high. Although the action of inserting the tray is simple and easy to learn, cutting and inserting, commonly called as a three-knife method, the planting area is large, so that the labor intensity is huge. The efficiency of the sunflower receptacle can be greatly reduced due to the fact that the labor workers are few and the same action is repeated repeatedly.

The manual inserting plate has high harvesting cost. The average cost of hiring workers per person in the sunflower transplanting tray investigation process is about 300-500 per day, and the labor cost is huge due to the large sunflower planting area.

Along with the improvement of life quality of people, the demands of the market for sunflower seed oil and sunflower seeds are increased year by year. However, in recent 10 years, the growing speed of the planting area of the sunflower is slow and the sunflower tends to slide downwards, mainly because the manual harvesting efficiency is low, the cost is high and the harvesting difficulty is high, and the development of the sunflower industry is restricted.

one path is that power is transmitted from a power output shaft (501) of the tractor to a lower gear box (502), the lower gear box (502) is fixed on a walking platform (6) and is connected with an upper gear box (504) positioned right behind a cab through a vertical power transmission shaft (503), and the power is transmitted to a two-way power conversion box (506) through a horizontal power transmission shaft (505); one output end of the two-way power conversion box (506) transmits power to a rear gear (207) of a conveying chain through a power shaft (208) of the conveying chain, and then transmits power to the trapezoid cutter (101) through a conveying chain (205); the other output end of the two-way power conversion box (506) transmits power to the rectangular cutter (106);

The other path is that power is transmitted from a power output shaft (501) of the tractor to two front gear boxes (507) which are symmetrical on two sides with the cab as a center, and the power is transmitted to a rear gear box (509) through a power transition shaft (508); the front gear box (507) and the rear gear box (509) are respectively arranged on the walking platform (6), and the front gear box (507) and the rear gear box (509) respectively transmit power to the walking wheels (603) through wheel power shafts (5010).

10. The self-propelled working machine for sunflower cutting discs and inserting discs according to claim 1, wherein the ratchet (301) and the cylindrical gear (406) are synchronously driven by the electric push rod (4017), and when the chute push rod (305) drives the disc turning plate (3011) to rotate to the left limit position, the disc cam (4012) drives the platen (4015) with the rod to move above the disc turning plate (3011); when the chute push rod (305) drives the turnover plate (3011) to rotate to be vertical and horizontal, the disc cam (4012) drives the platen (4015) with the rod to move to an inlet of the fixed barrel (4016); when the chute push rod (305) drives the turnover plate (3011) to rotate to the right limit position, the disc cam (4012) drives the platen (4015) with the rod to extend into the fixed barrel (4016).
