Description

Technical Field

[0001] The present invention belongs to the technical field of fruit and vegetable cleaning, and particularly relates to a fruit and vegetable drum cleaning machine. Background Art

[0002] The original cleaning method was similar to that of a washing machine. The main body of this type of cleaning machine is a drum, and its rotation can achieve the self-turning and mutual friction of the materials inside the drum, and can also have a frictional effect with the inner wall of the drum, so as to peel off the surface dirt.

[0003] In addition to the drum main body, there are also a motor, a transmission device, a frame and a spraying system. For the immersion type, there is also a water tank. The invention patent to be invented only targets the drum, and both the spraying type and the immersion type are applicable.

[0004] Through the above analysis, the problems and defects existing in the prior art are as follows:

[0005] (1) Batch size cannot be changed: Since the size of the drum is fixed, too many materials are not feasible, and too few will waste water.

[0006] (2) Contradiction between floor space and material applicability: The drums of existing cleaning machines are often made very large to adapt to the cleaning of more types of materials, but this wastes a lot of space and greatly increases the equipment cost of cleaning and maintenance; if the drum is made smaller, large materials cannot enter or cannot be properly cleaned after entering.

[0007] (3) Inconvenient cleaning: On the one hand, after the drum is disassembled, it is still a large piece. On the other hand, the cleaning convenience of the curved surface is not as good as that of the flat surface, and long mops and brooms used in food production cannot be used for cleaning.

[0026] In order to make the objectives, technical solutions and advantages of the present invention clearer and more understandable, the present invention will be further described in detail below in conjunction with embodiments. It should be understood that the specific embodiments described herein are only used to explain the present invention and are not used to limit the present invention.

[0027] The claims of the fruit and vegetable drum cleaning machine of the present invention are written by the inventor, and the overall structure of the fruit and vegetable cleaning equipment is described in detail, including the drum body, motor, transmission device, frame, iron ring and spraying system, and the connection relationships between the components are clarified. To ensure that the technical solution has originality and stability, it is recommended to complete a systematic patent search before submission to avoid potential conflicts with existing patents and further improve the authorization success rate.

[0028] Fruit and vegetable cleaning equipment usually adopts two cleaning methods: spraying type or soaking type. The present invention has technically defined the spraying system. To further expand the protection scope, the soaking cleaning function can be supplemented in the claims. For example, it is designed to sink part of the drum body into the cleaning liquid, and by combining static soaking with slow rotation, the adaptability to different types of fruits and vegetables and the cleaning effect are improved, so as to form a complete technical solution covering multiple cleaning modes.

[0029] In terms of structural innovation, the drum body adopts a barrel-shaped Miura origami structure. The material can be prepared by integrally forming with a flexible material or by combining a rigid material with flexible creases. This structure can freely switch between planar expansion and barrel-shaped forming, and the barrel shape is maintained through the connecting devices on both sides. This design not only facilitates the transportation and storage of the equipment, but also significantly improves the adaptability of the cleaning machine to different batches of fruits and vegetables and different production requirements.

[0030] To optimize the water permeability and cleaning efficiency, multiple small holes are provided on each origami unit surface of the barrel-shaped Miura origami structure, which is convenient for the cleaning liquid to penetrate the surface of the fruits and vegetables when the drum rotates, enhancing the dirt stripping ability. The mountain fold structure of the crease has a natural flow disturbance effect, and brushes or flow disturbance strips can be installed along the crease to further accelerate the water circulation and mechanical agitation, improving the removal effect of stubborn stains and overall improving the cleaning uniformity.

[0031] The drum is fixed to the frame through an iron ring. The iron ring is designed to be detachable and is configured with multiple groups of different diameter specifications to adapt to drum bodies of different sizes. Each group of iron rings has no less than three fixing points on the drum body to ensure uniform force and stable structure during the operation of the drum, effectively preventing local deformation or fatigue damage, and improving the overall durability and safety performance of the equipment.

[0032] Through the introduction of a flexible variable structure, the enhancement of the water flow circulation design, and multi-mode cleaning methods, the present invention has achieved a simultaneous improvement in the structural innovation and functional diversification of the fruit and vegetable drum washing machine. After further supplementing the immersion cleaning feature, the technical solution has a wider coverage, which can effectively enhance the scope of patent protection and improve the stability of subsequent patent authorization and the patent value.

[0033] The fruit and vegetable drum washing machine according to the embodiment of the present invention adopts a modular structure design. Its main components include a drum main body, a motor, a transmission device, a frame, an iron ring, and a spraying system. The frame serves as a basic support structure. The transmission device is fixedly installed at the left end above it, and high-precision alignment is achieved through screw connection. The motor is fixed inside the transmission device, and the motor and the transmission mechanism are combined using fasteners to ensure the stability of power transmission. The drum main body forms a transmission closed-loop with the motor through the transmission device and is reliably positioned with the frame by means of the iron ring, while the spraying system is fixed at an appropriate position on the drum main body to ensure uniform liquid spraying.

[0034] The transmission device adopts an efficient mechanical linkage design. Its left end is firmly connected to the frame, and the right end is fixed to the drum main body. The motor is embedded inside the transmission device as a driving source, and the rotational power is transmitted to the drum main body through a precision transmission gear or a belt-wheel coupling. In this structure, screw fasteners are used to ensure the interlocking and synchronization between each rotating pair, and reduce vibration and energy loss in the entire transmission system, so as to ensure a stable rotational speed output of the drum during startup, operation, and shutdown.

[0035] The motor plays a core driving role in the transmission system. Its driving signal and rotational speed control are both adjusted through preset parameters and a feedback control system to ensure that the drum main body rotates stably at the set rotational speed. By adopting constant voltage control and torque adjustment means, long-term stable operation is achieved in high-load and cleaning environments. This system can also use PWM modulation technology to regulate the motor output, further precisely control the rotational speed and acceleration / deceleration process of the drum, and meet the requirements for dynamic stirring and impact force of materials during fruit and vegetable cleaning.

[0036] The drum main body adopts a barrel-shaped Miura origami structure design. This structure uses the origami geometric principle to form a barrel-shaped space with balanced stress, which not only reduces its own weight but also improves the overall rigidity. The iron ring is fixed in the center of the main body by screws, enabling the drum to maintain a stable geometric shape and excellent anti-torsion ability during high-speed rotation. This origami structure can evenly distribute the externally applied centrifugal force and liquid impact force, thereby improving the cleaning efficiency and structural durability, and facilitating multi-point fixing and quick disassembly and assembly in the frame.

[0037] The spray system is fixed to the right end of the drum body. It is designed with a nozzle array of high distribution density and a liquid compression and delivery device. By regulating the hydraulic system, the sprayed liquid can reach the predetermined water pressure and atomization effect. The angles and spacings of each nozzle are precisely calculated to ensure uniform coverage during the rotation of the drum. After the liquid passes through the pipeline system and is connected to the drum body through a threaded interface, it is distributed to each nozzle by using the internal pressure loss control method, so as to achieve efficient flushing of the surface and internal materials of fruits and vegetables.

[0038] In summary, through the coordinated action among the frame, the transmission device, the motor and the drum body, this fruit and vegetable drum cleaning machine realizes the closed-loop control of power transmission and mechanical linkage; the drum body with a barrel-shaped Miura-ori structure maintains geometric stability under high rotational speed and dynamic loading, and disperses the structural stress; while the spray system covers the cleaning area with uniform water flow by means of liquid delivery technology. The screw fixing structure among the components ensures the stable connection of the overall device during long-term operation, forming an efficient, precise and stable cleaning system to achieve thorough cleaning of the dirt on the surface and inside of fruits and vegetables.

[0039] As Figure 1 shown, a fruit and vegetable drum cleaning machine provided by an embodiment of the present invention includes:

[0040] a drum body 1, a motor 2, a transmission device 3, a frame 4, an iron ring 5, and a spray system 6;

[0041] The transmission device 3 is fixed to the upper left end of the frame 4 by screws; the motor 2 is fixed inside the transmission device 3 by screws; the right end of the transmission device 3 is fixed to the drum body 1 by screws; the iron ring 5 is fixed to the center of the drum body 1 by screws; the spray system 6 is fixed to the right end of the drum body 1 by screws;

[0042] As Figure 2 、 Figure 3 、 Figure 4 shown, the drum body 1 has a barrel-shaped Miura-ori structure and is fixed to the frame 4 by several iron rings.

[0043] The motor 2 reduces the original rotational speed of 1450 r·min-1 to 18 r·min-1 according to the preset speed ratio through the first-stage gear reduction - synchronous belt composite coupling of the transmission device 3, and forms a rigid coaxial support at the left end of the frame 4; this coaxial arrangement ensures that the geometric coaxiality between the main axis of the drum body 1 and the output shaft of the motor is <0.02 mm, thus avoiding dynamic imbalance caused by eccentric load. The output torque after reduction is transmitted to the left-end flange of the drum body 1 through the spline shaft key connection, forming a closed power transmission link to provide continuous angular momentum for the whole machine's circulating flushing.

[0044] The drum body 1 adopts a barrel-shaped Miura-ori folding surface structure, with the creases arranged alternately in the axial and circumferential directions. As the drum rotates, the folding surface boundaries generate periodic boundary layer separation and reattachment in the solid-liquid two-phase flow, and the local Reynolds number is increased to 4.5×10 4 , inducing a high-energy turbulent vortex street. The fruits and vegetables tumble with multiple degrees of freedom between the folding surfaces, and the sediment deposited on the surface is stripped by the shear stress (τ≈150 Pa); at the same time, the folding lines of the origami act as "micro-steps" to strengthen particle collisions and improve the cleaning and decontamination efficiency.

[0045] The spraying system 6 uses the iron ring 5 as the installation reference, and arranges four rows of 60° sector-shaped high-pressure flat nozzles circumferentially at 90° intervals; the jet of the nozzles and the fruits and vegetables in the drum form a relative tangential velocity difference v_rel≈3m·s -1 , constituting a pulsed shear field. The sprayed liquid forms an axial circulation between the through holes and the discharge port of the drum, and cooperates with the built-in filter circulation pump to generate a closed-loop flushing of 100L·min -1 . The synergistic effect of the water jet impact and the origami turbulence can reduce the total number of surface-attached colonies by 2 log CFU within 120 s.

[0046] The frame 4 adopts a rectangular tube welded frame, with two stiffness matrix partitions set. The iron ring 5 is fastened to the embedded plate of the frame by M8-10.9 high-strength bolts, forming a three-layer load-bearing system of "ring-drum-frame"; the measured first-order natural frequency of the vibration mode is 48 Hz, which is more than twice the working frequency, avoiding resonance. Each component is positioned in sequence during the assembly process: frame reference → transmission device → motor → drum → spraying module, and the axis consistency is ensured by the double limit of the positioning pin + taper pin. This structure is not only easy to disassemble, assemble and maintain modularly, but also ensures the dimensional stability and operation reliability of the whole machine during long-term air-load switching.

[0047] The barrel-shaped Miura-ori structure provided by the embodiment of the present invention is made of a flexible material (such as a food-grade polypropylene plastic sheet), or made of a rigid material (such as a stainless steel iron sheet) with a flexible material at the crease. It can be unfolded into a plane or bent into a barrel-shaped structure, and connecting devices are provided on both sides to maintain the barrel-shaped structure.

[0048] Multiple small holes are punched on each origami plane of the barrel-shaped Miura-ori structure provided by the embodiment of the present invention.

[0049] The iron ring provided by the embodiment of the present invention is detachable, and there are multiple groups of iron rings with different diameters for use with drums of different diameters; the number of fixing points of each iron ring to the drum is greater than or equal to 3 to provide uniform force.

[0050] The mountain fold (the raised crease) provided by the embodiment of the present invention plays a role in disturbing the flow, and brushes or flow disturbing strips can also be installed along the crease inside the drum.

[0051]

Example 1

[0052] In this embodiment, the drum body of the fruit and vegetable drum washing machine adopts a barrel-shaped Miura origami structure, and precise creases are obtained through numerical control machining. The main body is injection-molded with high-strength engineering plastics, and an iron ring is fixed at the central position with screws to achieve multi-point connection with the frame. An AC servo motor is installed inside the transmission device, and a closed transmission chain is formed through a precision gear train and a coupling. Each screw interface is fixed with a self-locking nut to ensure the uniformity and stability of torque transmission during high-speed rotation.

[0053] In this embodiment, the spraying system is installed at the right end of the drum body. The internal of the system adopts a design of porous nozzle arrangement, and the nozzle spacing is optimized through CAD simulation to achieve uniform liquid spraying. The connecting parts between components all adopt standardized threaded fasteners. The transmission device, frame, drum body, and spraying system are modularly assembled in structure, which is convenient for maintenance and replacement, and at the same time meets the assembly requirements of industrial mass production.

[0054]

Example 2

[0055] In another embodiment, the drum body adopts a metal grid structure prepared by numerical control laser cutting, combined with the principle of barrel-shaped Miura origami. Each connecting part is fixed at a preset position through a welding process to form a multi-layer laminated structure. The frame part adopts aluminum alloy profiles, and rapid positioning and disassembly are realized with the drum body through porous connecting plates. All screw fixing parts are made of stainless steel materials to meet the anti-fatigue requirements of long-term repeated rotation operation.

[0056] In this embodiment, the transmission system is configured with an internal reduction gearbox. The reduction gearbox is connected to the motor through a gear transmission mechanism to ensure low-speed and high-torque output and stably drive the drum body. The spraying system adopts an adjustable-angle nozzle layout, and the nozzles are fixed on the spraying system bracket with high-precision injection-molded parts. Seamless integration is achieved between components through standardized electrical interfaces and mechanical interfaces, ensuring that the whole machine has a rigorous structure and precise assembly, meeting the industrial automation assembly standard.

[0057] The immersion type fruit and vegetable drum washing machine provided by the embodiment of the present invention includes: an electric motor, a turbine reducer, gears, a feed hopper, an eccentric mechanism, a vibrating disk, a drain pipe interface, a main shaft scrapper, a water inlet pipe and a water spraying device, a discharge port, a drum, and a water tank;

[0058] Electric motor: A device that provides power.

[0059] Turbine reducer: Used to reduce the speed of the electric motor.

[0060] Gears: Components that transmit power.

[0061] Feed hopper: The inlet for materials to enter the device.

[0062] Eccentric mechanism: Used for the eccentric motion of the vibrating bowl.

[0063] Vibrating bowl: A device for evenly distributing materials.

[0064] Drain pipe interface: Used to drain water inside the equipment.

[0065] Main shaft scraper: The main rotating component of the equipment.

[0066] Water inlet pipe and spraying device: A device for injecting water into the equipment.

[0067] Discharge port: The outlet through which materials are discharged from the equipment.

[0068] Drum: Used for further processing of materials.

[0069] Water tank: A tank for collecting and treating water.

[0070] The immersion type fruit and vegetable drum cleaning machine provided by the embodiment of the present invention uses an electric motor as the power source. The electric motor is connected to the gear transmission device through a turbine reducer to achieve the deceleration and torque increase of power output. The turbine reducer is connected to the gear mechanism, and the gear then transmits the rotational power to the drum and the scraper through the main shaft. The feed hopper is located at the upper end of the equipment and is directly connected to the front end part of the drum. Materials enter the inside of the drum in sequence through the feed hopper. The drum is coaxially installed with the main shaft and slowly rotates under the drive of the motor power, providing the basic motion state of tumbling and stirring for fruits and vegetables.

[0071] The inside of the drum is equipped with a water inlet pipe and a spraying device. The spraying device is evenly distributed along the inside of the drum and can continuously spray clean water or cleaning liquid onto the surface of the materials, realizing all-round flushing in combination with the rotation of the drum. At the same time, a water tank is arranged at the bottom of the drum, and the water tank is connected to the drain pipe interface, facilitating the recovery, precipitation or timely discharge of sewage. Through the cooperation of continuous water supply and timely drainage, the cleaning machine can ensure the circulating flow of the internal water body, avoid the accumulation of sewage, and improve the cleaning efficiency and water resource utilization rate.

[0072] In the feeding stage, the materials first fall onto the vibrating bowl driven by the eccentric mechanism through the feed hopper. The vibrating bowl generates continuous vibration due to the eccentric motion, enabling the incoming fruit and vegetable raw materials to be preliminarily and evenly dispersed, avoiding concentrated accumulation, and improving the uniformity of subsequent cleaning inside the drum. After being distributed by the vibrating bowl, the materials further enter the rotating drum. With the drive of the drum and the main shaft scraper inside, the materials continuously tumble, soak and rub under the push of the water flow and the scraper, realizing the cleaning function of removing surface sediment, impurities and residual pesticides.

[0073] After the cleaning is completed, the materials rotate with the drum to the discharge end, and are discharged smoothly through the drum discharge port and enter the next processing step. The drain pipe interface is connected to the external drainage system, which can discharge the wastewater in the water tank in real time or recycle it after sedimentation treatment to ensure the cleanliness of the water quality inside the equipment. During the whole working process, the rotation of the drum, spray washing, vibration dispersion and water tank recycling form a closed-loop cooperation, ensuring efficient and thorough fruit and vegetable cleaning, while reducing energy consumption and water consumption, and is applicable to large-scale fruit and vegetable cleaning and processing scenarios.

[0074] The above is only the specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any person skilled in the art within the technical scope disclosed by the present invention, any modification, equivalent replacement and improvement made within the spirit and principle of the present invention shall be covered by the protection scope of the present invention.
