[0011] Preferably, one end of the DC water pump is connected to the water tank through a pipeline, and the other end of the DC water pump is connected to multiple groups of the sprinkler head components through pipelines.

[0012] Compared with the prior art, the beneficial effects of the present invention are as follows:

[0013] The leek harvester of the present invention has the following important components: a leek clamping mechanism, a leek cutting mechanism, a leek packaging mechanism and a nutrient solution spraying mechanism; the leek clamping mechanism is provided with an adaptive guide trough, which can gather loose leeks and improve the harvesting efficiency of leeks. The whole mechanism is composed of a fixed diverter trough in the middle and movable rectifying troughs on both sides. The movable rectifying trough is composed of a first connecting buckle of a connecting bayonet and a first spring push rod. The connecting buckle integrates a limiting device and a movable bearing into one, giving the movable rectifying trough the ability to move on a plane. The spring push rod is connected to the movable rectifying trough so that the cantilever of the movable rectifying trough is close to the limiting device. The working process is that the fixed diverter trough diverts dense leeks from the middle guide trough to the movable rectifying troughs on both sides. Leeks accumulate in the movable rectifying trough, forcing the movable rectifying trough to open outwards. The spring push rod pushes the movable rectifying trough tightly, which can keep the clamping force of the belt on the leeks consistent, so that the belt does not fall during the leek transportation process.

[0014] 2. The leek harvester is also equipped with a belt tensioning device, which consists of a spring push rod, a second spring push rod, a connecting bearing, a connecting bearing base, and a second limit device. When the movable rectifier trough in the front opens to both sides due to too many leeks, the belt tensioning device comes into play. Since the transmission device is connected to the frame by the connecting bearing base, the second spring push rod pushes the transmission device backward slightly to compensate for the expansion capacity of the belt; because this machine has a multi-terrain adaptability function, when the leek harvesting site changes, it is necessary to lift and lower the harvesting parts in front as needed. The belt tensioning device will move with the harvesting parts in front, so that the belt will not be too loose or too tight, affecting the harvesting efficiency and the life of the belt;

[0015] 3. The belt drive structure on this device uses two encoder motors as the basic power for clamping the belt, and the two gears mesh with each other to realize the object rotation of the belt, thereby realizing the next stage of continuous transportation of leeks; the leek cutting mechanism uses a TT high-speed right-angle motor to directly drive the blade to rotate and cut the leek; the cutting device uses a rear-placed cutting blade, so that when the belt is clamped in the middle of the leek, the leek is cut off from the root, which greatly improves the success rate of clamping the leek and the chance of the leek not falling; the cutting lifting device is mainly composed of a lifting electric push rod, a bearing connection buckle and a cutting The overall composition of the device is that when the lifting electric push rod retracts, the cutting device in the front is lifted up as a whole, and when the lifting electric push rod is extended, the cutting device in the front moves downward as a whole; this structure is used to adapt to different sites and different cutting lengths of leeks; in the leek packaging mechanism, the machine can place the leeks on the leek flip plate, and the leeks are collected here. The bundling wire shortening device has a wire feeding gear here; through the cooperation of various components in the packaging mechanism, the classification and packaging of leeks are completed. This kind of leek harvester not only improves agricultural production efficiency, but also ensures the quality of crops. It is one of the indispensable tools in modern agriculture and improves the practical performance of the device.

[0016] 4. The multifunctional leek harvester proposed in the present invention is also provided with a nutrient solution spraying mechanism. The nutrient solution required for use is pre-filled in the water tank. In order to subsequently maintain the leek, the nutrient solution in the water tank is extracted by the DC water pump on the device, and the nutrient solution is sprayed out through multiple groups of nozzles on the front side of the device, so that the nutrient solution is evenly sprayed on the surface of the leek. The device is also provided with a motion mechanism. The main power of the machine is rear-wheel drive. The horizontally opposed stepping motor is directly output to the differential as the main power, which reduces the power loss in the mechanical transmission. At the same time, it cooperates with the front steering mechanism, such as the steering connecting rod, to achieve a smaller turning radius; the front steering mechanism adopts a steering mechanism connected to the steering connecting rod, which makes the steering more flexible and powerful. This setting improves the overall working efficiency of the device, not only enables the leek to have a cutting function, but also facilitates the subsequent maintenance of the leek, which can be completed without the help of external environment equipment, reducing the working cost, improving the scope of application of the equipment, and improving the functional practicality of the device.
