The transmission roller 42 is provided with an upper support rod 42-2 and a lower support rod 42-1. A front shaft is connected with a driven wheel 42-3, and a rear shaft is connected with a driving wheel 42-4. A rear upper support rod 42-2 is fixed with a box 44-1 on one side.

The transmission roller 42 is fixed with the first frame 2 through a locking screw. The hexagonal shaft 24 on the first frame 2 passes through the box 44-1 of the transmission roller 42. The power of the rotating hexagonal shaft 24 is transmitted to the driving wheel 42-4 through the bevel gears. The hexagonal shaft 24 is connected with a motor outside the first frame 2, which drives the hexagonal shaft to rotate. The special-shaped clamping belt 43 has two layers.

The two sets of wavy guardrails at the bottom are closed and connected by a connecting rod. The upper opening of the spring-tooth conveying trough is the same as that of the adjacent non-circular conveyor belt, and the lower end narrows. The two sets of wavy guardrails 84 and the bottom slides form a conveying track. The leafy vegetables slide down one by one inside the two semi-circular wavy guardrails on the left and right, and finally enter the secondary conveying mechanism horizontally. The 8-tooth conveyor trough comes in two types: one is shorter with its tail located at the innermost part of the secondary conveyor, and the other is longer with its tail located in the middle of the secondary conveyor mechanism. The 8-tooth conveyor troughs are arranged with alternating lengths to prevent leafy vegetables from crowding when sliding from the primary conveyor mechanism to the secondary conveyor mechanism.
