[0093] The user stands behind the main vehicle body, puts a number of rubber bands 619 on the rubber band conveying belt one 609, the rubber band conveying belt two 610, the rubber band conveying belt three 611, and the rubber band conveying belt four 612, holds the handrail 102 with his hand, pushes the main vehicle body 100 to move forward, and manually opens the cutting driving motor 208 and the rear roller driving motor one 305 and the rear roller driving motor two 306. At this time, the harvesting device 200 and the belt conveying device 300 in front begin to work. The leek growing in the soil is guided by the conical table-shaped converging device 201, enters from the front end of the belt conveying device 300, and is clamped by the conveying belt one 303 and the conveying belt two 304. The root of the leek is cut off by the cutting blade 202, and then is conveyed upward and falls into the V-shaped collection space formed by the metering flat plate 402 and the sliding table 401 while being clamped by the conveying belt one 303 and the conveying belt two 304. At this time, the metering flat plate 402 is in theFigure 5b As shown in the position, when the leeks fill the V-shaped collection space, the user first stops the main vehicle body 100, and drives the metering plate 402 to rotate to the position shown in the figure by rotating the metering plate drive motor 404. Figure 5e And Figure 5f As shown in the position, at this time, the leeks in the V-shaped collection space can slide together along the slide table 401 to the lower collection and shaping device 500. The leeks in the collection and shaping device 500 are vertically arranged.

[0094] The user manually opens the baling device drive motor 620 switch, and the baling device drive motor 620 starts to work. Under the action of the crank 621, the connecting rod 622, the bracket guide rod one 623 and the bracket guide rod two 624, the bracket 617 moves vertically and linearly from the highest point to the lowest point. At this time, about two-thirds of the vertically arranged leeks in the collection and shaping device 500 are located inside the bracket 617. Then the user manually opens the four rubber band conveyor drive motor switches, and the rubber band conveyor drive motor one 613, the rubber band conveyor drive motor two 614, the rubber band conveyor drive motor three 615 and the rubber band conveyor drive motor four 616 start to work, driving the pulley one 601, the pulley three 603, the pulley five 605 and the pulley seven 607 to rotate, thereby further driving the rubber band conveyor one 609, the rubber band conveyor two 610, the rubber band conveyor three 611 and the rubber band conveyor four 612 to move. When the lowest rubber band moves to the bottom end of the pulley two 602, the pulley four 604, the pulley six 606 and the pulley eight 608, it automatically falls off and is tightly wrapped around the leeks in the collection and shaping device 500, realizing the leek baling operation. The user controls the four rubber band conveyor drive motors to stop rotating.

[0095] At this time, the eccentric circular plate 701 is in the position shown in the figure. Figure 8b The user manually opens the eccentric circular plate drive motor 706, and the eccentric circular plate drive motor 706 starts to work. After driving the eccentric circular plate 701 to rotate to the position shown in the figure through the pinion 705 and the gear 702, the leeks baled in the cylindrical hole 501 at the lower end of the collection and shaping device 500 can automatically fall to the ground under the action of gravity, completing the discharging operation. The user controls the eccentric circular plate drive motor 706 to reverse, so that the eccentric circular plate 701 returns to the starting position shown in the figure. The user controls the baling device drive motor 620 to reverse, so that the bracket 617 runs upward to the highest point. At this time, the leek baling operation is completed, and the user can continue to push the main vehicle body 100 forward to enter the next working cycle. Figure 8d Figure 8b
