[0015] The utility model is further described below in conjunction with the accompanying drawings.
[0016] Reference Figure 1 to Figure 6 , a harvesting system applied to a self-propelled harvester, installed on a walking system, comprising a harvesting mechanism and a screw mechanism for moving the harvesting mechanism up and down, the harvesting mechanism being installed on the screw mechanism, and the screw mechanism being installed on a front side frame of the walking system;
[0017] The harvesting mechanism includes a shearing plate 10, a cutting side plate 16, two seedling supporting side plates 3, 4, two trapezoidal grain supporting frames 1, 2, two thirty-eight-degree seedling supporting inclined blocks 5, 6 and a cutting knife. The rear end of the shearing plate 10 is installed on the cutting side plate 16, the cutting side plate 16 is installed on the screw mechanism, the two thirty-eight-degree seedling supporting inclined blocks 5, 6 are installed on the front part of the shearing plate 10, the two seedling supporting side plates 3, 4 are symmetrically installed on the left and right ends of the shearing plate 10, the two trapezoidal grain supporting frames 1, 2 are inclined forward and downward and are symmetrically installed on the two seedling supporting side plates 3, 4 respectively, and a grain supporting opening for leeks to enter is formed between the two trapezoidal grain supporting frames 1, 2, and the grain supporting opening is a structure that is wide at the bottom and small at the top. The cutting knife is installed at the bottom of the shearing plate 10 and is connected to the power output end of the DC motor 8. The DC motor 8 is located behind the thirty-eight-degree seedling supporting inclined block and is installed on the shearing plate 10.
[0018] The cutting knife adopts a movable and fixed knife structure, including two cutting blades 13 and 14, which are respectively a movable blade and a fixed blade. The two cutting blades 13 and 14 are installed at the bottom of the shearing plate 10 through the cutting knife connecting parts 7 and 15. The pressing plate 9 is located above the shearing plate 10, and the movable blade is connected to the power output end of the DC motor. The DC motor 8 is arranged between the two cutting knife connecting parts 7 and 15, and the cutting blades 13 and 14 are driven by the DC motor 8. The pressing plate 9 connects the shearing plate 10 and the cutting knife connecting parts 7 and 15 to reduce the vibration and looseness generated by the cutting knife when cutting.
[0019] The middle part of the cutting knife connecting piece is raised. The cutting knife is kept at a vertical distance of 5 to 7 cm from the ridge, which is conducive to maintaining the quality and efficiency of leek harvesting and can ensure that the damage to the leek roots is minimized.

[0021] The cutting principle of the utility model is: through the movement of the movable blade and the support of the fixed blade, the relative position and movement between the cutting knife and the harvested material are controlled, so as to realize efficient and fast cutting; the actual working process is that according to the actual height between the ridges, the slider of the screw mechanism slides up and down, so that the cutting knife is lowered to 3 to 5 cm from the height of the ridge. During the translational movement of the walking system, the seedling-like harvested material enters the supporting mouth of the harvesting mechanism, and is guided to the cutting position by the 38-degree seedling supporting inclined blocks 5 and 6, and the DC motor 8 enables the cutting blade to realize fast cutting and harvesting.
[0022] The actual working scenario of this harvesting system is mainly the harvesting of seedlings in some rural field ridges. The height of the harvesting knife can be adjusted according to the height of the field ridges. It can efficiently cut the plants while effectively protecting the roots, which is suitable for continuous harvesting of seeds.
