[0008] Preferably, guide arcs are provided between adjacent guide cones of adjacent conveyor belt groups to push the spinach to the sides. Since the sides of the conveyor belts of adjacent conveyor belt groups move downward, the guide arcs are provided to guide the spinach to the sides to prevent the spinach from entering the space between the adjacent conveyor belt groups.

[0009] Preferably, the lowest position of the cutting blade extending out is lower than the bottom surface of the guide cone. The guide cone is higher than the soil surface to avoid generating additional resistance, and the cutting blade needs to be inserted into the soil when extending to cut the spinach roots.

[0010] Preferably, the upper ends of the left conveyor belt and the right conveyor belt are respectively provided with driving pulleys and the lower ends are respectively provided with driven pulleys, and the lower surface of the conveying plate is provided with a conveying motor that drives the driving pulleys, and each driving pulley is independently controlled or linked controlled.

[0011] Preferably, the cutting blade as a whole is a first-level sawtooth, and each cutting edge of the first-level sawtooth of the cutting blade is a second-level sawtooth.

[0012] Preferably, a weighing sensor is provided at the bottom of the material box.

[0013] Preferably, a front wheel and a rear wheel are provided at the bottom of the frame, the front wheel is a universal driven wheel, the rear wheel is a driving wheel, and a travel motor for driving the driving wheel is provided on the frame.

[0014] Preferably, the top surface of the material box is not higher than the upper end of the conveying plate.

[0015] The utility model cuts the roots of spinach and automatically completes the collection of the cut spinach. The device has a simple structure and is easy to operate. Multiple conveyor belt groups are provided to harvest multiple rows of spinach at the same time. BRIEF DESCRIPTION OF THE DRAWINGS
