AI Technical Summary
Traditional multi-brush cleaning equipment is prone to causing material jamming when cleaning root and stem materials, and the cleaning effect is not good.
The brush on a single disc works in conjunction with an agitator. The agitator rotates in the same direction as the disc but at a different speed, creating a coordinated up-and-down motion. Combined with water flow and centrifugal force, this achieves 360-degree tumbling cleaning, preventing gaps from getting stuck.
It significantly reduces the risk of material jamming, improves cleaning efficiency and effectiveness, protects the integrity of the root and stem epidermis, and reduces cleaning dead spots.

Technical Field
[0001] This application relates to the field of cleaning machine technology, and in particular to a fully automatic cleaning machine for root and stem plants. Background Technology
[0002] In agricultural product processing and food manufacturing, cleaning root vegetables (such as potatoes, sweet potatoes, radishes, and ginger) is an important pre-treatment step. These materials often contain impurities such as mud, soil, and pesticide residues, and their surfaces may have uneven textures or grooves, posing many challenges to traditional cleaning methods.
[0003] With the increase in mechanization, some mechanical equipment for cleaning root and stem materials has appeared on the market. Most existing cleaning equipment cleans materials through methods such as stirring and brush scrubbing. However, these devices have certain design flaws. For example, traditional multi-brush roller equipment usually uses multiple sets of rollers rotating in opposite directions, and the gaps formed by the fixed arrangement of the rollers can easily cause material to get stuck.

[0015] The technical solutions in this application will be clearly and thoroughly described below with reference to the accompanying drawings. In the description of the embodiments of this application, unless otherwise stated, " / " means "or," for example, A / B can mean A or B. "And / or" in the text is merely a description of the relationship between related objects, indicating that three relationships can exist. For example, A and / or B can represent: A existing alone, A and B existing simultaneously, and B existing alone. Furthermore, in the description of the embodiments of this application, "multiple" refers to two or more than two.
[0016] Hereinafter, the terms "first" and "second" are used for descriptive purposes only and should not be construed as implying or suggesting relative importance or implicitly indicating the number of technical features indicated. Thus, a feature defined as "first" or "second" may explicitly or implicitly include one or more of that feature.
[0017] Please see Figure 1 This application provides a fully automatic root and stem cleaning machine, including a material tank 10, a stirring mechanism 20, and a cleaning mechanism 30. It is understood that the root and stem materials in this application include, but are not limited to, potatoes, sweet potatoes, and snow lotus fruit. In this application embodiment, snow lotus fruit is used as an example for description.
[0018] Specifically, the material tank 10 has a material cavity 10a and an inlet 10b and a outlet 10c connected to the material cavity 10a. The material cavity 10a is the core container for the cleaning operation, providing space for the cleaning process. The inlet 10b is located at the upper end of the side wall of the material tank 10, and the outlet 10c is located at the lower end of the side wall of the material tank 10. It is understood that the material tank 10 is also provided with a water inlet pipe 10d and a drain pipe 10e connected to the material cavity 10a. The water inlet pipe 10d can be used to inject tap water, and the drain pipe 10e is used to discharge the water after the cleaning is completed.
[0019] The stirring mechanism 20 includes a first drive assembly 21 and a stirring element 22. The first drive assembly 21 is connected to the material tank 10. The first drive shaft of the first drive assembly 21 extends to the material chamber 10a and is rotatably connected to the stirring element 22. The cleaning mechanism 30 includes a first drive assembly 21, a disc 32, and a brush 33 disposed on the disc 32. The first drive assembly 21 is connected to the material bucket 10, and the second drive shaft of the first drive assembly 21 extends to the material cavity 10a and is rotatably connected to the disc 32. The stirring element 22 is located above the disc 32. The stirring element 22 and the disc 32 rotate in the same direction, but the stirring element 22 and the disc 32 rotate at different speeds.
[0020] In this embodiment, the stirring element 22 and the disc 32 and brush 33 rotate in the same direction, forming a coordinated motion of "upper layer stirring and tumbling + lower layer brush 33 chasing and brushing": The agitator 22 uses a high rotation speed to lift and throw the yacon into the working area of the disc 32 and brush 33, thereby breaking down the mud clump structure attached to the surface of the material. The brush 33 performs directional brushing of the snow lotus fruit at a relatively low rotation speed. The difference in relative linear velocity between the brush 33 and the material can remove stubborn impurities and avoid skin damage caused by reverse friction.
[0021] During the cleaning process of the yacon, the inlet 10b, outlet 10c, water inlet pipe 10d, and drain pipe 10e are all closed. After cleaning, the wastewater is discharged through the drain pipe 10e. Alternatively, the inlet 10b and outlet 10c can be closed, while the water inlet pipe 10d and drain pipe 10e are connected, allowing water to be added, cleaned, and discharged simultaneously. After cleaning, the outlet 10c is opened, and the centrifugal force generated by the rotation of the agitator 22 and the disc 32 throws the yacon out through the outlet 10c.
[0022] In this embodiment, the stirring component 22 is mainly responsible for dispersing and turning the material to prevent the snow lotus fruit from accumulating; while the brush 33 below focuses on surface brushing. This three-dimensional cleaning mode with the upper and lower parts working together reduces cleaning dead corners compared to a single cleaning method (such as relying solely on roller rolling or relying solely on air bubbles).
[0023] Furthermore, compared to traditional multi-fixed-gap roller brushes that are prone to causing material jamming, the brushes 33 on the disc 32 are distributed in a planar pattern with more flexible gaps. Combined with the mixing element 22, this allows for continuous material displacement, significantly reducing the risk of jamming. Simultaneously, the gentle brushing combined with water flow is more effective in protecting the integrity of the root and stem epidermis than purely mechanical impact.
[0024] In some of these embodiments, please refer to Figure 1The fully automatic root and stem cleaning machine in this embodiment of the application also includes a lifting machine 40, which has a feeding end 41 and a discharging end 42 arranged opposite to each other, and the discharging end 42 is connected to the feeding port 10b.
[0025] The elevator 40 can be a belt elevator 40 or a scraper elevator 40. These are products currently available on the market. We will not provide a further description of the specific structure here.
[0026] By directly aligning the discharge end 42 of the elevator 40 with the feed inlet 10b of the cleaning machine, the material, after being lifted, can automatically and smoothly enter the cleaning machine by gravity or auxiliary devices. This avoids material accumulation and waiting in intermediate stages, ensuring the continuity of the production line.
[0027] On the other hand, by using the elevator 40 to directly transport the yacon from the ground to the high-level feed inlet 10b, the physical exertion of the operators and the number of personnel required are significantly reduced, thus lowering labor costs.
[0028] In one embodiment of this application, a first baffle is provided at the feed inlet 10b. The first baffle is connected to a third drive assembly, which is used to drive the first baffle to move so as to open or close the feed inlet 10b. A second baffle is provided at the discharge outlet 10c. The second baffle is connected to a fourth drive assembly, which is used to drive the second baffle to move so as to open or close the discharge outlet 10c.
[0029] The first and second baffles can move in either a translational or a flipping manner. The driving method can be pneumatic (pneumatic push rod) or electric (micro electric push rod). In one embodiment, taking the first baffle as an example, it is a circular or arc-shaped steel plate. One side is hinged to the edge of the feed inlet 10b via a pin, and the other side is connected to a pneumatic push rod. It flips upwards around the pin to open the feed inlet 10b, and then closes due to gravity and a spring, achieving a seal with a silicone sealing ring. The second baffle works similarly. Since opening the baffles or cabinet doors electrically or pneumatically in a barrel-shaped structure is a fairly mature technology, its working principle and structure will not be further described here.
[0030] Therefore, the following method can be used to realize a fully automatic root and stem cleaning machine: This equipment uses a PLC intelligent control system as the control center. It collects status signals in real time through a sensor group (photoelectric sensor, liquid level sensor, pressure sensor) and combines them with a preset cleaning program to achieve a complete process of "feeding-cleaning-draining-discharging" without human intervention.
[0031] After the operator selects the cleaning program on the interface and presses the "Start" button, the PLC sends a start signal to the hoist 40 drive unit and simultaneously sends an "Open Door" command to the third drive component. After the preset time is reached, the elevator 40 is immediately stopped and the feed inlet 10b is closed.
[0032] Both the inlet pipe 10d and the outlet pipe 10e have solenoid valves. In the first embodiment, when the inlet port 10b is closed, the PLC opens the solenoid valve of the inlet pipe 10d to inject clean tap water into the material chamber 10a. After a preset time is reached, the solenoid valve of the inlet pipe 10d is closed, and the PLC sends a signal to the first drive component 21 and the second drive component 31 to start stirring and cleaning the snow lotus fruit. After a preset time is reached, the PLC opens the solenoid valve on the outlet pipe 10e to complete the drainage.
[0033] In the second embodiment, the PLC opens the solenoid valve of the water inlet pipe 10d to inject clean tap water into the material chamber 10a. At the same time, the PLC sends signals to the first drive component 21 and the second drive component 31 to achieve simultaneous spraying and cleaning of the snow lotus fruit. During this process, the solenoid valve on the drain pipe 10e is always in the open state to facilitate timely discharge of sewage.
[0034] In the second embodiment, neither the inlet pipe 10d nor the outlet pipe 10e may be equipped with a solenoid valve. The inlet pipe 10d may be directly connected to the external water tank via a water pump, and the PLC may directly control the switching on and off of the water pump, as well as the pumping time.
[0035] After cleaning is completed, the PLC sends a signal to the fourth drive assembly to open the door of the second baffle plate. The snow lotus fruit is then thrown out to the discharge port 10c by the centrifugal force generated by the rotation of the disc 32 and the agitator 22 and discharged. Then the PLC sends a signal to the first drive assembly 21 and the second drive assembly 31 to stop rotating, thus completing the entire "feeding-cleaning-draining-discharging" process.
[0036] In one embodiment of this application, please refer to Figures 1 to 3 The stirring component 22 includes a stirring shaft 221 and a plurality of silicone plates 222. The stirring shaft 221 can be connected to the first drive shaft via a coupling, and the plurality of silicone plates 222 are connected to the side wall of the stirring shaft 221 along the circumference of the stirring shaft 221.
[0037] The surface of the silicone plate 222 is made of a flexible material, which reduces the rate of skin damage when in contact with the yacon. Furthermore, in this embodiment, the silicone plate 222 is an arc-shaped plate, arched in the direction of rotation, thus more effectively guiding the water flow and the movement of the yacon. When the arc-shaped plate rotates forward, its arched surface acts like an airplane wing, guiding the yacon along the arc surface for easy discharge from the discharge port 10c.
[0038] Furthermore, in this embodiment, since the stirring element 22 and the disc 32 rotate in the same direction, and the silicone plate 222 (stirring element 22) and the brush 33 of the disc 32 rotate in the same direction, the centrifugal projectile force and the tangential friction force on the material are in the same direction, forming a "combined force boosting" effect. After the material is thrown out by the silicone plate 222, it moves at a faster speed (forward) than the disc 32. At this time, the rotation direction of the brush 33 of the disc 32 is the same as the flight direction of the material, and it will not generate a reverse resistance force on the material, so that the material can also be thrown out through the discharge port 10c.
[0039] Furthermore, both the disc 32 and the agitator 22 are spaced apart from the inner wall of the material container 10. Preferably, the gap between the disc 32 and the agitator 22 and the inner wall of the material container 10 is 5mm. This can prevent the disc 32 and the agitator 22 from interfering with the material container 10 when they rotate, and also prevent root materials from getting stuck between the edge of the disc 32, the edge of the agitator 22 and the inner wall of the material container 10, thus ensuring the smoothness of the material during cleaning.
[0040] On the other hand, the brush 33 and the agitator 22 are spaced axially on the first drive shaft, and the distance between them can also be 5mm. The axial gap divides the inside of the material bucket 10 into an "upper tumbling zone" and a "lower brushing zone", forming a stepped cleaning process. The upper mixing element 22 throws the material upward at a high speed, using centrifugal force to remove loose mud and sand adhering to the surface of the material, thus achieving initial cleaning. Under the influence of gravity, the material falls to the lower layer through the axial gap and is finely scrubbed by the brush 33 rotating in the same direction, thus achieving secondary cleaning.
[0041] Please continue reading. Figure 1 In one embodiment of this application, a mechanical frame 50 is also included. The mechanical frame 50 is disposed at the bottom of the material bucket 10 to support the material bucket 10. The mechanical frame 50 forms an installation cavity 50a, and the second drive assembly 31 is disposed in the installation cavity 50a.
[0042] like Figure 1 As shown, the second drive assembly 31 includes a motor power part, a drive part such as a transmission belt and a transmission wheel. By placing the second drive assembly 31 in the mounting cavity 50a, the reliability of the overall operation can be guaranteed.
[0043] In this embodiment, the power source of the first drive component 21 is also a motor, which is purchased from a commercially available product. Therefore, its installation method and specific principle will not be described in detail here.
[0044] The above-disclosed embodiments are merely preferred embodiments of this application and should not be construed as limiting the scope of this application. Therefore, any equivalent variations made in accordance with the claims of this application shall still fall within the scope of this application.
