Description

Technical Field

[0001] The utility model relates to the technical field of mechanical equipment, in particular to a large-angle flushing integrated lotus root harvesting device. Background Art

[0002] Lotus roots generally grow in rivers, ponds, still waters or slow-flowing lakes and other water bodies. They grow in deep soil layers with high soil viscosity. At present, lotus roots in my country are mainly harvested manually or semi-mechanically and semi-manually. Manual harvesting mainly involves directly pulling out the fruits with a single-point force or using a high-pressure water gun to flush the silt to harvest the fruits. Harvesting is difficult, inefficient and labor-intensive, and the labor cost is high. At the same time, harvesting is greatly affected by environmental factors. Semi-mechanically and semi-manually mainly use the existing lotus root harvesting machinery on the market, which is manually pushed in the water. It has a low degree of automation, is highly dependent on labor, and has low environmental adaptability. At the same time, the manufacturing cost is high.

[0003] There are some problems or shortcomings in the traditional lotus root harvesting technology in some aspects. These problems may limit the speed, efficiency and scope of application of lotus root harvesting. The following are some common problems or shortcomings of lotus root harvesting technology: 1. Poor adaptability to different water depth environments: Traditional lotus root collection devices, such as jet-type lotus root diggers, cannot adjust the spray height of the nozzle. When encountering deep water areas, their work efficiency is greatly reduced; 2. Limited jet area: Traditional lotus root digging devices, such as floating bucket duckbill lotus root diggers, cannot adjust the spray angle of the nozzle, and can only spray water at a fixed angle, which greatly limits the spray area; 3. Poor mobility: Traditional lotus root harvesting devices, such as boat-type lotus root diggers, cannot be remotely controlled or automatically walked, and one person is required to push it underwater to operate; 4. Unable to achieve integrated harvesting: Traditional lotus root picking machinery, such as self-propelled hydraulic lotus root digging machines, can complete the collection work through water jets, but cannot realize the collection function.

[0004] In order to overcome these problems, new agricultural machinery, such as crawler self-propelled hydraulic lotus root harvesters, are being developed to provide more efficient lotus root harvesting solutions. After overcoming the shortcomings of traditional technologies, these new technologies have gradually reduced the cost of harvesting lotus roots, improved collection efficiency, and promoted the development of lotus roots and their by-products.

[0005] Therefore, it is necessary to provide a large-angle flushing harvesting integrated lotus root harvesting device, which has the advantages of high degree of automation, remote operation through the Web terminal, high efficiency in harvesting lotus roots, low cost and no damage to lotus roots during the harvesting process.

The following are the technical problems solved by the lotus root harvesting device with integrated large-angle flushing harvesting: 1. Expansion of the flushing range: Traditional lotus root harvesting machinery arranges the nozzles in a straight line, which cannot flush the lotus roots on both sides of the front end of the machine. There is a disadvantage of a small flushing range. The nozzles are arranged in a semi-circular arc, which can make the impact water flow flush the lotus roots in a fan-shaped range with a larger radius in front, and also have an effect on the lotus roots on both sides of the machine. 2. Improved flushing effect: The nozzle can rotate freely in the vertical direction. During the rotation and rotation process, the lotus roots can be repeatedly flushed, so that the silt that binds the lotus roots is completely detached to ensure high-quality harvesting of lotus roots. 3. Improved adaptability to underwater depth: The nozzle of the large-angle flushing harvesting integrated lotus root harvesting device can rotate and rise and fall at the same time, and can be adjusted according to different water depth environments to ensure that it can always be close to the silt, adapt to the different water depths in the lotus field, and improve the effect of impacting the lotus root. 4. Improved collection quality of lotus roots: The lotus roots are collected by crawlers with lotus hooks and stored in the collection basket. During this process, the lotus hooks can ensure that the lotus roots are collected without slipping. 5. Simple and stable structure: In order to overcome the problem of complex structure of some existing machines, the most complex water jet system mainly adopts planetary gear sets and screw transmission structures, which are simple and easy to maintain. 6. The overall structure is simple and easy to mass produce: The machine has no complex transmission structure, and each functional system is easy to control, which can reduce the cost of mass production of the machine. 7. Remote control and monitoring: Equipped with a high-performance intelligent control system, it can perform remote control and real-time information recording, which can improve work efficiency and reduce labor costs. In short, the large-angle flushing integrated lotus root harvesting device optimizes the water jet system and adopts a planetary gear mechanism and a screw transmission structure to control the rotation and lifting of the nozzle, so that it can improve its adaptability and operating efficiency to different water depth environments. At the same time, it is equipped with a belt collection device to achieve integrated harvesting.

[0062] The solar panel 8 and the battery 49 provide electric energy for the water pump 14. The water pump 14 extracts water from the pond and pressurizes the water. The water is transported to the four-way water divider 44 through the hose 43. The four-way water divider 44 divides the water into four ways and transports it to the water jet pinion nozzle 22 through the hose 43, and then transports it to the water jet nozzle 15. The nozzle sprays high-pressure water to wash the silt covering the lotus root. After the silt around the lotus root is completely removed, the lotus root floats up by itself. The planetary reduction motor 46 drives the rotating long shaft 34 to rotate, thereby rotating the impeller 18 to provide forward thrust for the fuselage. During the forward movement of the fuselage, the GA25-370 reduction motor 27 drives the upper rotating shaft 4 of the collection system to rotate, thereby rotating the crawler chain mesh belt 5. The lotus root hook 25 buckled on the crawler chain mesh belt 5 grabs the collected lotus root and transports it to the collection basket 2, realizing the integrated lotus root harvesting.

[0063] When the water jet nozzle 15 sprays high-pressure water, the steering gear 39 drives the transmission shaft 38 to rotate and then drives the water jet pinion nozzle 22 to rotate, thereby rotating the water jet nozzle 15. This process enables the device to flush silt over a large area at the same position, greatly improving the efficiency of lotus root collection.

[0064] At the same time, during the rotation process, the screw motor 50 fixed to the upper layer 6 of the frame rotates, driving the screw to rotate and thus enabling the vertical moving layer 11 of the frame to move up and down. Since the water jet system is fixed to the vertical moving layer 11 of the frame, the water jet system moves vertically during its vertical movement. This function allows the water jet nozzle 15 to be lowered as the depth of the sludge being flushed decreases, so that the water jet nozzle 15 is always close to the sludge, further improving the collection efficiency. At the same time, this function enhances the device's ability to adapt to different water depth environments, and has a wider range of applications than traditional lotus root harvesters.

[0065] Although the implementation scheme of the utility model has been disclosed as above, it is not limited to the applications listed in the specification and the implementation scheme. It can be fully applied to various fields suitable for the utility model. For those familiar with the art, additional modifications can be easily implemented. Therefore, without departing from the general concept defined by the claims and the scope of equivalents, the utility model is not limited to the specific details and the illustrations shown and described herein.
