The leaf vegetable shoveling supporting mechanism 34 is arranged on the flip shaft 33, and the flip shaft 33 is rotatably arranged on the support frame 32. The flip motor 31 is used to drive the flip shaft 33 to rotate to realize the flipping of the leaf vegetable shoveling supporting mechanism 34, so that the leaf vegetable shoveling supporting mechanism 34 scoops up and lifts the hydroponic leaf vegetables to separate them from the harvesting tray 22. The leaf vegetable shoveling supporting mechanism 34 includes a connecting plate 344, a shovel plate 343 and a horizontal insert plate 342. The connecting plate 344 is tilted downward on the flip shaft 33. The connecting plate 344 is concave and has two connecting arms. The end of the connecting arm A fixing ring 341 is provided, which is fixedly sleeved on the flip shaft 33. A through slot 321 is provided on the support frame 32 for the connecting arm to pass through when flipping upward. The through slot 321 is also U-shaped, and the opening faces outward.

[0032] The working principle of the leafy vegetable shovel supporting mechanism 34: under the action of the first conveying mechanism 2, each hydroponic leafy vegetable in the front row is embedded in the U-shaped area of ​​the corresponding shovel plate 343, and the flip shaft 33 rotates and flips, driving the leafy vegetable shovel supporting mechanism 34 to flip, and lift up the entire row of hydroponic leafy vegetables. During the flipping process, the hydroponic leafy vegetables will lean on the horizontal insertion plate 342, which plays a supporting and anti-slipping role. In addition, the horizontal insertion plate 342 and the shovel plate 343 form a V-shaped accommodating space, which further avoids the slipping of hydroponic leafy vegetables during the flipping process and ensures the stability of the operation. In addition, the leafy vegetable shovel supporting machine 34 constitutes an arrow-shaped shovel supporting structure. Such a structure better ensures the stability of the operation during the lifting and flipping movement of the hydroponic leafy vegetables, and greatly avoids the phenomenon of hydroponic leafy vegetables slipping during the flipping process due to the lack of a support plate.

The second conveying mechanism 4 is perpendicular to the first conveying mechanism 2. Specifically, the collection area is a collection box, which is located at the end of the conveying direction of the conveyor belt 42. The collection box can be placed on the ground. The collection box is used to receive hydroponic leafy vegetables that fall from the conveyor belt 42.

[0034] The brush root separation mechanism 1 of the present invention can realize the breaking of the roots of hydroponic leafy vegetables. The first conveying mechanism 2 conveys the hydroponic leafy vegetables at a uniform speed along the extension direction of the belt 23. During the movement, it passes through the brush root separation mechanism 1. The two root brush bars 15 are driven by the reverse motor 11 and the forward motor 12 to rotate in opposite directions. This operation breaks the roots of the hydroponic leafy vegetables during the movement. The harvesting plate 22 continues to move until the first row of ...

[0035] Furthermore, when the leafy vegetable shovel supporting mechanism 34 lifts up the entire row of hydroponic leafy vegetables, the first conveying motor 21 drives the belt 23 to move in the opposite direction for a fixed distance, that is, the first conveying motor 21 drives the belt 23 to move in the opposite direction, thereby causing the harvesting plate 22 to move in the opposite direction for a fixed distance. This process avoids the adhesion and lifting of the hydroponic leafy vegetables to be harvested while lifting up the hydroponic leafy vegetables to be harvested, and also avoids the leafy vegetable shovel supporting mechanism 34 causing crushing to the hydroponic leafy vegetables to be harvested in the rear row when returning to the harvesting position after harvesting the hydroponic leafy vegetables in the first row.

[0036] The whole design structure of the application is simple, the processing cost is low, and the separation of the roots of the water-cultivated leafy vegetables is ensured, which is different from the traditional root cutting harvesting. The water-cultivated characteristics and commodity value of the water-cultivated leafy vegetables are maintained while avoiding the adverse effects of the mutual connection between the roots of the water-cultivated leafy vegetables on subsequent leaf peeling and packaging activities.

[0040] 3) The water-cultivated leafy vegetables are conveyed to the shovel overturning mechanism 3, that is, the frontmost row of water-cultivated leafy vegetables is embedded in the U-shaped area of the shovel plate 343, the leafy vegetable shovel supporting mechanism 34 is driven by the overturning motor 31 to support the whole row of water-cultivated leafy vegetables, at the same time, the first conveying motor 21 drives the belt 23 to move in the opposite direction by a fixed distance and remains stationary, the leafy vegetable shovel supporting mechanism 34 overturns to unload the water-cultivated leafy vegetables onto the second conveying mechanism, and then the leafy vegetable shovel supporting mechanism 34 overturns back to the initial position;

[0041] 4) The second conveying mechanism 4 conveys the water-cultivated leafy vegetables into the collection box;

[0042] 5) Steps 3) and 4) are repeated until the harvesting of all the water-cultivated leafy vegetables on the harvesting disc 22 is completed.
