Embodiment Construction

[0023] The working mode of the present invention is described in detail below in conjunction with each accompanying drawing, as figure 1 As shown, lettuce 4 is planted in the planting hole 5 on the planting plate 3, after the lettuce 4 matures, the planting plate 3 is transported to the position of the lettuce cutting and harvesting device by the transport carrier 1 in the transport tank 2; figure 2 As shown, in the process that the planting plate 3 continues to move forward, the double helix rod 15 in the cutting and harvesting device will completely pull out the lettuce 4 from the planting hole 5, and under the joint action of the supporting baffle plate 9 and the top conveyor belt 7 Next, the lettuce 4 that will be extracted continues to be transported obliquely upwards until the root of the lettuce is transported to the root conveyor belt 10 and the position of the lettuce to be cut is close to the cutting tool 22; The conveyor belt 10 is also automatically delivered to t...

Abstract

The invention discloses a device for cutting and harvesting lettuces cultivated on field planting plates and belongs to the technical field of agricultural mechanical automation. The device comprises a drawing mechanism, a supporting mechanism, a root conveying mechanism, a harvesting device, a control system and the like, a double-helix rod in the drawing mechanism can draw out a whole lettuce in each field planting hole, the supporting mechanism mainly consists of a lettuce baffle, a top conveying belt and a double-helix rod and ensures that lettuces are smoothly cut and harvested, the root conveying mechanism makes the cut lettuces conveyed to designated positions in a unified mode, the harvesting device makes the cut lettuces automatically conveyed to a lettuce collecting box, the control system mainly controls the speeds of drive systems through a single chip microcomputer, accordingly the energy consumption is reduced, and a best operating effect is achieved. The device is reasonable in structure, high in operating efficiency, reliable in use and convenient to adjust, produces few faults and can achieve mechanization and automation of harvesting operation of a plant factory.

Description

technical field [0001] The invention discloses a cutting and harvesting device for cultivating lettuce with a planting board, in particular to a device for cultivating lettuce with a planting board and automatically cutting and harvesting it, which is widely used in facility agricultural plant factories, and belongs to the technical field of agricultural machinery automation. Background technique [0002] Plant factory is recognized as the most advanced form of facility agriculture. It uses artificially built facilities to precisely control the environment inside the facility. The growth of crops is almost not affected by the external environment, so it has low requirements for the planting area; The growth rate is faster and the utilization rate per unit of land is higher. Therefore, plant factories have developed rapidly in recent years. [0003] The scientific name of lettuce is leaf lettuce, which is an annual herb of Compositae. It has high nutritional value. It is one...
