Description

Technical Field

[0001] This utility model relates to the field of lotus root harvesting technology, specifically to an adaptive lotus root harvesting machine based on water depth conditions. Background Technology

[0002] Lotus root, scientifically known as *Nelumbo nucifera*, is an aquatic plant widely cultivated in Asia. Its rhizome, known as lotus root, is an important food and medicinal herb. Traditionally, lotus root harvesting relied on manual labor, which was not only labor-intensive but also inefficient. Especially with rising labor costs, this traditional method can no longer meet the needs of modern agriculture. While technological advancements have led to the development of mechanized lotus root harvesting methods, existing techniques still have limitations, such as poor adaptability to water depth, unsatisfactory harvesting efficiency and quality, complex operation, and high costs.

[0003] In the field of lotus root harvesting technology, there are currently various harvesting methods, including manual and mechanical harvesting. While manual harvesting is flexible, it is labor-intensive, inefficient, and its economic viability is declining due to rising labor costs. Mechanical harvesting can improve efficiency, but current equipment often has poor adaptability to water depth conditions and is prone to damaging lotus roots during the harvesting process, resulting in a high breakage rate and affecting the quality and market value of the lotus roots. Furthermore, existing lotus root harvesting machinery is often limited in function and has a low degree of automation, failing to meet the high-efficiency harvesting needs under different paddy field conditions.

[0004] Therefore, based on the above-mentioned technical problems, it is necessary for those skilled in the art to develop an adaptive lotus root harvesting machine based on water depth conditions. Utility Model Content

[0005] The purpose of this invention is to provide an adaptive lotus root harvester based on water depth conditions to solve the problems mentioned in the background art.

[0006] To achieve the above objectives, this utility model provides the following technical solution:

[0007] A technical solution for an adaptive lotus root harvester based on water depth conditions includes a frame. Motor bases are symmetrically arranged on the top of the frame, and a forward / backward moving motor is mounted on each motor base. Gears are connected to the output ends of the forward / backward moving motors, and a rack meshes with the gears below them. Two motor bases are connected by a reinforcing rod, and two sets of adaptive spring cylinders are mounted on the reinforcing rod. A cantilever is connected to the tail end of each adaptive spring cylinder. A forward and reverse spiral roller is located at the front end of the cantilever, and high-pressure nozzles are located on adjacent sides of the forward and reverse spiral rollers. A drive motor is installed inside the frame, and a cantilever belt drive assembly is located at the output end of the drive motor. The cantilever belt drive assembly is connected to the forward and reverse spiral rollers.

[0008] As a preferred technical solution, a walking motor is installed on both sides of the bottom of the frame, and a walking belt drive assembly is provided at the output end of the walking motor, and a track float type walking device is installed on the walking belt drive assembly.

[0009] As a preferred technical solution, a cleaning box is provided at the tail end of the cantilever, a cleaning motor is provided on the outside of the cleaning box, a cleaning chain drive assembly is connected to the output end of the cleaning motor, multiple sets of cleaning brush rollers are connected to the cleaning chain drive assembly, the multiple sets of cleaning brush rollers are located inside the cleaning box, and a collection box is provided at the tail end of the cleaning box.

[0010] As a preferred technical solution, the cleaning box is provided with multiple sets of rinsing pipes, and a water pump is installed at the bottom of the frame, which is used to supply water to the rinsing pipes and the high-pressure nozzle device.

[0011] As a preferred technical solution, a collection motor is provided below the cleaning box, the output end of the collection motor is connected to a collection belt drive assembly, the collection belt drive assembly is connected to a collection conveyor belt, and an auxiliary collection frame is provided below the collection conveyor belt.

[0012] As a preferred technical solution, the auxiliary collection frame is connected to eccentric wheels at both ends, and the eccentric wheels are connected to the collection belt drive assembly to realize the reciprocating motion of the auxiliary collection frame. A collection baffle is installed at the front end of the auxiliary collection frame.

[0013] As a preferred technical solution, a top cover is installed on the top of the rack, the top cover is used to protect the internal components, and an inspection door is installed on the top cover, with a control module located below the inspection door.

[0014] Compared with the prior art, the beneficial effects of this utility model are:

[0015] This invention relates to an adaptive lotus root harvester based on water depth conditions. Employing a forward and reverse spiral mechanism and adaptive arm technology, it effectively scrapes the surface soil to both sides, quickly removing hardened topsoil. This solves the problem of harvesting deep soil and compacted soil, which is difficult in traditional techniques. The adaptive arm automatically adjusts the height of the mechanism according to soil hardness, thereby reducing damage to the lotus roots during harvesting.

[0016] In addition, we adopted a high-pressure nozzle device with a main and auxiliary nozzle design. The main nozzle is equipped with multiple high-pressure nozzles and achieves multi-angle spraying through a cam mechanism, significantly increasing the flushing area in a single operation and quickly separating the lotus root from the soil. At the same time, the auxiliary nozzle performs a secondary flushing of the soil and cleans the forward and reverse spiral mechanism. This not only improves the efficiency of lotus root harvesting but also prevents lotus root strips and other debris from getting tangled in the equipment, ensuring continuous operation of the equipment.

[0017] To address the problem in existing technologies where lotus roots are covered by mud after being sprayed by high-pressure nozzles, preventing them from floating to the surface in time and resulting in missed harvesting, a stirring and spraying mechanism is added. This mechanism stirs the lotus roots in the muddy water a second time and applies an upward force, causing the lotus roots to float quickly, thereby reducing the missed harvesting rate.

[0018] Integrating conveying, cleaning, and storage functions, it quickly transports lotus roots to the collection box, effectively solving the problems of low lotus root collection efficiency and high labor costs in traditional technologies, realizing intelligent lotus root collection, and reducing the damage rate of lotus roots.

[0019] In terms of control, intelligent remote modules and IoT technology were adopted to automate and remotely control the lotus root harvesting operation, making the harvesting process unmanned. This not only improved the intelligence level of the equipment but also significantly reduced labor costs. Attached Figure Description

[0025] The features and exemplary embodiments of various aspects of this utility model will now be described in detail. To make the objectives, technical solutions, and advantages of this utility model clearer, the following description, in conjunction with the accompanying drawings and specific embodiments, will provide a further detailed description. For those skilled in the art, this utility model can be implemented without some of these specific details. The following description of the embodiments is merely intended to provide a better understanding of this utility model by illustrating examples.

[0026] like Figure 1 , Figure 2 , Figure 3 and Figure 4 As shown, this utility model provides a technical solution for an adaptive lotus root harvester based on water depth conditions: the frame 1 serves as the main structure of the entire harvester, and a top cover 11 is installed on its top to protect the internal components. A maintenance door 12 is also installed on the top cover 11, and a control module is located below the maintenance door 12 to control the operation of the harvester.

[0027] The bottom two sides of the frame 1 are equipped with walking motors 41. The output end of the walking motors 41 is equipped with a walking belt drive assembly 42. The walking belt drive assembly 42 is equipped with a tracked float-type walking device 43, which enables the harvester to walk smoothly in the lotus root field.

[0028] Two motor mounts 3 are connected by a reinforcing rod 36. Two sets of adaptive spring cylinders 34 are mounted on the reinforcing rod 36, and cantilever 35 is connected to the tail end of the adaptive spring cylinder 34. A forward and reverse spiral roller 37 is located at the front end of the cantilever 35, and a high-pressure nozzle device 38 is located on the adjacent side of the forward and reverse spiral roller 37. A drive motor 39 is installed in the frame 1. A cantilever belt drive assembly 391 is provided at the output end of the drive motor 39. The cantilever belt drive assembly 391 is connected to the forward and reverse spiral roller 37 and drives the forward and reverse spiral roller 37 to rotate.

[0029] A cleaning box 5 is located at the tail end of the cantilever 35. A cleaning motor 51 is installed on the outside of the cleaning box 5. The output end of the cleaning motor 51 is connected to a cleaning chain drive assembly 52. ​​Multiple sets of cleaning brush rollers 53 are connected to the cleaning chain drive assembly 52. ​​The multiple sets of cleaning brush rollers 53 are located inside the cleaning box 5 and are used to clean the lotus roots. A collection box 2 is installed at the tail end of the cleaning box 5 to collect the cleaned lotus roots.

[0030] The cleaning box 5 is equipped with multiple sets of rinsing pipes, and a water pump is installed at the bottom of the frame 1. The water pump is used to supply water to the rinsing pipes and the high-pressure nozzle device 38.

[0031] A collection motor 61 is installed below the collection box 2. The output end of the collection motor 61 is connected to a collection belt drive assembly 62, which is connected to a collection conveyor belt 63. An auxiliary collection frame 65 is installed below the collection conveyor belt 63. Eccentric wheels 64 are connected to both ends of the auxiliary collection frame 65. The eccentric wheels 64 are connected to the collection belt drive assembly 62 to realize the reciprocating motion of the auxiliary collection frame 65. A collection baffle 66 is installed at the front end of the auxiliary collection frame 65 to guide the lotus root into the collection conveyor belt 63.

[0032] With the above structure, the adaptive lotus root harvester of this utility model can automatically adjust the harvesting height according to the water depth conditions, reduce damage to the lotus root, improve harvesting efficiency, and realize the automation and remote control of lotus root harvesting operations through intelligent remote module and Internet of Things technology, which significantly reduces labor costs and improves the level of intelligence.

[0033] According to the above scheme, in this embodiment, the operator can start the harvester through remote control equipment. During harvesting, the harvester reaches the designated lotus field and controls the cantilever 35 to descend to a suitable height. As the harvester moves forward, the forward and reverse spiral rollers 37 scrape away the surface soil layer and push down and remove the lotus stalks. The high-pressure nozzle device 38 at the front end flushes away the first layer of silt in the lotus field and assists in cleaning the mud on the forward and reverse spiral rollers 37. The high-pressure nozzle at the rear end swings and washes away the second layer of silt. At the same time, the swinging and washing can flush out the lotus roots growing in the same direction as the harvester, improving harvesting efficiency. After the lotus roots are flushed out, they follow the harvester... The lotus root is moved forward and floats to the front and below the conveyor belt. The auxiliary collection frame 65 moves in an elliptical trajectory to prevent the lotus root from slipping under the collection conveyor belt 63. The medium-pressure water flow sprayed by the auxiliary nozzles agitates the water in front and below the conveyor belt, causing the lotus root to float up quickly and reach the conveyor belt. The collection baffle 66 prevents the lotus root from drifting to the sides. The lotus root reaches the washing box 5 through the collection conveyor belt. After being washed in the washing box 5, it falls into the collection box 2. After the collection box 2 is full, the harvester is driven to the shore, the bottom plate of the collection box 2 is pulled out, and the lotus root is unloaded, completing one round of lotus root harvesting.

[0034] In summary, this adaptive lotus root harvester not only improves the efficiency and quality of lotus root harvesting operations, but also reduces labor costs through intelligent technology, providing strong support for the modernization of the lotus root planting industry.
