[0002] A greenhouse is a tool for facility cultivation, usually constructed of metal or plastic materials. It is mainly used to control environmental factors such as temperature, humidity and light, thereby providing relatively constant growth conditions, which is conducive to the growth and harvest of plants. Greenhouses can be used to grow vegetables and fruits. When harvesting fruits and vegetables in the greenhouse, transportation equipment is required to transport the picked fruits and vegetables.

[0003] In the prior art, a Chinese patent with publication number CN110341772A discloses a greenhouse vegetable, fruit and melon picking and transport vehicle, including a frame mounting plate, a support foot, a universal wheel and a vegetable basket, wherein four support feet are provided, and the top of the support foot is fixedly connected to the bottom of the frame mounting plate, the bottom of the support foot is fixedly connected to the top of the universal wheel, and one side of the top of the frame mounting plate is fixedly connected to a first support block. The present invention relates to the technical field of greenhouse vegetable, fruit and melon picking and transport vehicles. The greenhouse vegetable, fruit and melon picking and transport vehicle is fixedly connected to a first support block through one side of the top of the frame mounting plate, and a second support block is fixedly connected to the other side of the top of the frame mounting plate. One side of the top of the first support block is hinged with a mounting base plate through a hinge, and the side of the bottom of the mounting base plate away from the first support block is in contact with the top of the second support block, so that the vegetable basket can be loaded and unloaded by the transfer vehicle at one time, avoiding the problem of low efficiency of the existing unloading method.

[0004] The above-mentioned device operates by loading vegetable baskets onto trucks for transportation. However, in actual use, the temperature in the greenhouse is generally higher than the external temperature, so the water in the greenhouse evaporates quickly. If the fruits and vegetables are not moisturized after picking, the rapid evaporation of water will affect the quality of the fruits and vegetables after picking. Summary of the invention

[0005] The object of the present invention is to provide a fruit and vegetable picking and transportation device for a solar greenhouse to solve the problem of poor moisturizing effect mentioned in the above background technology.

[0006] To achieve the above-mentioned purpose, the present invention provides the following technical solutions: a fruit and vegetable picking and transporting device for a sunlight greenhouse, comprising a transport vehicle with a flat plate structure, the transport vehicle being slidably connected to a moving track fixedly installed on the ground inside the greenhouse, a power box for power supply fixedly installed on the upper right side of the transport vehicle, and picking frames neatly stacked on the top of the transport vehicle, and through holes are opened on the lower surface of the picking frames, and a protective mechanism for preventing the picking frames from tipping over is arranged on the left side of the transport vehicle; A water spraying mechanism for spraying water on the picked fruits and vegetables to keep them moisturized is arranged above the power box, and the water spraying mechanism includes a water storage tank fixedly installed on the upper surface of the power box and an atomizing nozzle fixedly installed above the water storage tank; a lifting mechanism for lifting the picking frame to reduce the bending operation of the staff is arranged above the transport vehicle.

[0007] Preferably, the protection mechanism comprises two protection plates on the left side of the transport vehicle, and a connecting rod for driving the protection plate to move is fixedly mounted at the bottom end of the protection plate.

[0008] Preferably, a buffer pad made of rubber is fixedly installed on the outer surface of the protective plate, and the connecting rod is fixedly installed between a telescopic cylinder fixedly installed inside the transport vehicle.

[0009] Preferably, a delivery pump connected to the atomizing nozzle is fixed on the upper surface of the water storage tank, and a connecting pipe is fixedly installed on the side of the water storage tank.

[0010] Preferably, the bottom end of the connecting pipe is communicated with a recovery tank fixedly installed inside the transport vehicle, and the recovery tank is communicated with a water leakage net fixedly installed on the upper surface of the transport vehicle.

[0011] Preferably, the lifting mechanism comprises two lifting plates installed above the transport vehicle, and two support rods are rotatably installed on the lower surface of the lifting plates, and a movable slider is rotatably installed on the lower end of the support rod.

[0012] Preferably, a transmission screw rod rotatably connected to the transport vehicle is installed through a thread inside the movable slider, and the transmission screw rod is driven by a servo motor.

[0013] Compared with the prior art, the beneficial effects of the present invention are as follows: the fruit and vegetable picking and transportation device for the solar greenhouse adopts a new structural design, and its specific contents are as follows: 1. Put the picked fruits and vegetables into the picking frame, and then stack the picking frame neatly on top of the transport vehicle. The transportation is achieved by sliding between the transport vehicle and the moving track. After loading is completed, the telescopic cylinder is turned on to drive the connecting rod to make the protective plate squeeze the picking frame to achieve the purpose of protection and avoid tipping during transportation.

[0014] Furthermore, during the transportation process, the delivery pump sprays the water in the water tank through the atomizing nozzle, so that the water is sprayed on the surface of the picked fruits and vegetables, achieving the purpose of moisturizing in a short time and avoiding the high temperature in the greenhouse to quickly evaporate the moisture of the fruits and vegetables.

[0015] Furthermore, excess water after spraying enters the recovery tank through the through holes and the water leakage net for recycling, and the recycled water is transported to the water storage tank through the connecting pipe. The water flowing in the connecting pipe can take away part of the heat of the power box to achieve the purpose of heat dissipation.

[0016] 2. During the loading and unloading process of the picking frame, the servo motor drives the transmission screw to rotate, so that the transmission screw drives the moving slider connected with the threaded connection on the outside to move, so that the support rod pushes the lifting plate upward, and moves the bottom picking frame upward, reducing the bending operation of the staff during loading and unloading.
