[0033] The present invention will now be described in further detail with reference to the accompanying drawings and embodiments. These drawings are simplified schematic diagrams that only illustrate the basic structure of the present invention in a schematic manner, and therefore only show components related to the present invention.

[0034] It's worth explaining that lotus roots, water chestnuts, and water caltrops (commonly known as horseshoes) all grow in fertile, organic-rich soils found in ponds, swamps, ditches, and paddy fields. Currently, lotus roots and water chestnuts are widely used in a variety of fields, including food service, healthcare, and health preservation. Demand is particularly high in the food service industry. Water chestnuts, on the other hand, are not only highly valued for their edible value but are also highly regarded for their exceptional medicinal properties, generating equally significant market demand.

[0035] The high-efficiency composite aquatic crop harvester provided by the utility model is used for picking the above-mentioned lotus roots, water chestnuts and water caltrops (commonly known as water chestnuts), but is not limited to the picking of these three aquatic crops.

[0036] like Figure 1 and Figure 2As shown, a high-efficiency composite aquatic crop harvester comprises a harvester body 1, a harvesting unit 2, a conveying unit 3, and a collection unit 4. The harvester body 1 is sequentially mounted with the harvester body 2, conveying unit 3, and collection unit 4. A water pump 5 is provided on the harvester body 1. One end of the water pump 5 is connected to both the harvesting unit 2 and conveying unit 3, and the other end is connected to a water source. The water pump 5 provides a stable water source for the harvesting unit 2 and conveying unit 3, ensuring a smooth harvesting process. Furthermore, the water pump enables the system to flexibly draw water from an external source, improving the adaptability and flexibility of the harvester.

[0037] The harvesting unit 2 is used to flush out aquatic crops growing in the mud; one end of the conveying unit 3 is used to gather the flushed aquatic crops and convey them to the other end. The water pump 5 draws water from the water source and sprinkles it onto the conveying unit 3 to clean the mud remaining on the surface of the aquatic crops. The other end of the conveying unit 3 cooperates with the collecting unit 4, and the aquatic crops fall into the collecting unit 4 for centralized processing.

[0038] like Figure 3 As shown, a fixed plate 1.1 is provided at one end of the harvester body 1 near the harvesting unit 2, and a regulating pump 1.2 is movably connected to the fixed plate 1.1. The harvesting unit 2 includes: a high-pressure nozzle 2.1, a mounting plate 2.2, a connecting pipe 2.3 and a U-shaped frame 2.4 fixed to the bottom of the mounting plate 2.2. One end of the regulating pump 1.2 is hinged to the U-shaped frame 2.4, and the connecting pipe 2.3 is fixed to the harvester body 1. One end of the connecting pipe 2.3 is connected to the water pump 5, and the other end is connected to the high-pressure nozzle 2.1. The regulating pump 1.2 is used to adjust the working height of the high-pressure nozzle 2.1.

[0039] Multiple high-pressure nozzles 2.1 are fixedly mounted on a mounting plate 2.2. A telescopic tube connects the nozzles 2.1 to the connecting pipe 2.3. This controls the extension and retraction of the support rod at the end of the regulating pump 1.2, as well as the tilt angle of the regulating pump 1.2, to adjust the height of the nozzles 2.1. The nozzles 2.1 effectively flush aquatic crops trapped in silt, improving harvesting efficiency. The regulating pump 1.2 allows the nozzles to be adjusted in height, accommodating aquatic crops at varying depths and enhancing the harvester's versatility. Furthermore, the telescopic tube further increases the nozzle's flexibility, facilitating adjustments to its position and angle based on actual needs.

[0040] like Figure 4 As shown, the conveying unit 3 includes: a conveyor belt 3.1, a tooth plate 3.2 and a leakage hole 3.3. The tooth plate 3.2 is located on the outer surface of the conveyor belt 3.1, and a leakage hole 3.3 is provided on the conveyor belt 3.1 between each two adjacent tooth plates 3.2. A water pipe 6 connected to a water pump 5 is provided on one side of the conveyor belt 3.1, and a sprinkler head for spraying clean water onto the conveyor belt 3.1 is provided on the water pipe 6.

[0041] The conveying unit 3 also includes baffles 3.4 fixed to both sides of the conveyor belt 3.1, a collection roller 3.5, and roller teeth 3.6 fixed to the collection roller 3.5. The roller teeth 3.6 and the tooth plate 3.2 are both made of rubber or silicone. During operation, the collection roller 3.5 is completely immersed in the water source and, by changing the fluctuations in the water source, transfers the flushed aquatic crops to the conveyor belt 3.1. The combination of the conveyor belt 3.1 and the tooth plate 3.2 effectively gathers and transfers the flushed aquatic crops, preventing them from being scattered and lost. The leak holes 3.3 allow excess water and soil to be drained away in a timely manner, reducing the burden of subsequent cleaning. The sprinkler head further cleans any residual soil on the crop surface, improving the cleanliness of the crop. The collection roller 3.5 and roller teeth 3.6 increase the efficiency and accuracy of crop collection, maintaining a stable collection effect, especially in situations with large water source fluctuations.

[0042] like Figure 5 、 6 As shown in Figure 7 , the collection unit 4 includes a collection frame 4.1, a buffer table 4.2, a fixed frame 4.3, and a rotating shaft 4.4. The fixed frame 4.3 is mounted and fixed to the harvester body 1. The collection frame 4.1 and the fixed frame 4.3 are rotatably connected via the rotating shaft 4.4. The buffer table 4.2 is located in the middle of the collection frame 4.1. The top of the buffer table 4.2 is higher than the height of the collection frame 4.1 and is located at the bottom of the conveyor belt 3.1. The collection frame 4.1 and the fixed frame 4.3 are rotatably connected via the rotating shaft 4.4, so that the angle of the collection frame can be adjusted as needed, facilitating the unloading and collection of crops. The buffer table 4.2 and the cushion reduce the impact of crops falling, protecting the integrity of the crops and improving the collection quality. In addition, the collection unit also makes the entire harvester more adaptable to different working environments and operational requirements.

[0043] The top of the buffer platform 4.2 is provided with a cushion made of rubber, silicone, or sponge. The bottom of the harvester body 1 is provided with a mounting groove into which the fixing bracket 4.3 fits. The angle formed between the collecting frame 4.1 and the fixing bracket 4.3 is 0 to 90 degrees.

[0044] When the utility model is used, first, start the harvester body 1 and ensure that the water pump 5 is connected to the water source to provide the necessary water flow for the entire system. The regulating pump 1.2 adjusts the working height of the high-pressure nozzle 2.1 according to the growth depth of the aquatic crops. By controlling the extension and tilt angle of the support rod at the end of the regulating pump 1.2, the precise adjustment of the nozzle position is achieved.

[0045] The water pump 5 draws water from the water source and delivers it to the high-pressure nozzle 2.1 through the connecting pipe 2.3. The high-pressure nozzle 2.1 releases high-pressure water flow to flush out the aquatic crops growing in the silt, preparing for subsequent treatment.

[0046] The flushed aquatic crops are captured by the collecting roller 3.5. The roller teeth 3.6 work in conjunction with the tooth plate 3.2 to effectively transfer the flushed aquatic crops to the conveyor belt 3.1 by changing the fluctuation in the water source. The tooth plate 3.2 on the conveyor belt 3.1 helps to gather the aquatic crops. At the same time, the leakage holes 3.3 allow excess water and soil to pass through, reducing the burden of subsequent cleaning. The sprinkler head on the water pipe 6 sprays clean water to further clean the soil remaining on the surface of the aquatic crops, thereby improving the cleanliness of the collected crops.

[0047] After cleaning, the aquatic crops travel along conveyor belt 3.1 to collection unit 4, where they ultimately fall onto buffer platform 4.2. A cushion on top of buffer platform 4.2 reduces the impact of the crops falling, protecting them from damage. The design of buffer platform 4.2 allows the crops to slide smoothly into collection basket 4.1 for subsequent centralized processing. Collection basket 4.1 is rotatably connected to fixed frame 4.3 via shaft 4.4, allowing for adjustment of angle as needed to facilitate unloading and collection of the crops.

[0048] During the entire harvesting process, the water pump 5 continuously supplies water to ensure the normal operation of each unit. According to actual conditions, the height of the high-pressure nozzle 2.1 can be adjusted by adjusting the pump 1.2, and the working conditions of the collecting roller 3.5 and the conveyor belt 3.1 can be adjusted to optimize the harvesting efficiency.

[0049] The above description is based on the ideal embodiment of the present invention. Based on the above description, relevant personnel can make various changes and modifications without departing from the technical scope of the present invention. The technical scope of the present invention is not limited to the content of the specification, but must be determined according to the scope of the claims.
