Description

Technical Field

[0001] This utility model relates to the field of fruit processing technology, specifically to a fruit spraying and washing machine. Background Technology

[0002] Guangxi is located in the subtropical monsoon zone, with an average annual temperature above 20℃. This results in relatively hot weather throughout the year, which, along with abundant rainfall, is beneficial for agricultural production. Guangxi is an important fruit production base in my country, especially for dragon fruit and Wogan tangerines. While dragon fruit is typically intercropped for aesthetic purposes and pest control, Wogan tangerines, due to their unique characteristics, are rarely intercropped. Currently, Wogan tangerines are generally sprayed with lime water for pest control. However, this lime water accumulates on the surface of the tangerines, making the ripe fruit unsightly and hindering sales. Therefore, after harvesting, Wogan tangerines usually undergo a fruit-wiping process. Currently, the basic procedure involves workers wiping the fruit with towels. While this method ensures quality and avoids scratching the skin of different tangerine stems during wiping, the overall work efficiency is low.

[0003] In response to this situation, some manufacturers have designed automatic fruit washing equipment, such as patent CN201820549715.6 - a fruit washing device for juice production. This patent features brush rollers inside the washing tank and water spray pipes above the tank, which simultaneously brush the fruit and apply water pressure, significantly improving the washing effect and efficiency. Furthermore, ultrasonic transducers at the bottom of the tank generate ultrasonic vibrations in the water medium, ensuring a more thorough cleaning. Air jets on the feed conveyor belt pre-blow away dirt from the fruit, reducing contamination of the water in the washing tank. However, this technology is primarily designed for washing fruit used in juice production. Secondly, the brush roller method can easily cause the fruit to collide with each other. If such equipment is used to wash Wogan oranges, which have relatively hard stems and are typically sold individually without further processing, the stems can easily scratch the surface of the oranges during washing, affecting the later sale of the whole fruit.

[0004] In view of the above, in patent CN202321502923.8 - a dragon fruit cleaning device, water is connected by a connector, water is drawn by a pumping mechanism and pressurized by a pressurizing device before entering the water storage chamber and sprayed downwards from a high-pressure nozzle. The dragon fruit is tumbled and conveyed backwards by the rotation of the conveyor rollers. During this process, it is cleaned by the spray of water from the high-pressure nozzles, and the surface of the dragon fruit is scrubbed by the cleaning brush during tumbling, thus thoroughly cleaning the dragon fruit and ensuring the cleaning effect. At the same time, the conveying rollers and the cleaning brush are made of soft bristles to reduce damage to the dragon fruit. Although this patent solves the problem of scratches caused by the collision of the fruit during the washing and soaking process, it is still difficult to remove some stubborn stains by relying solely on the combination of high-pressure spraying and cleaning brushes. A second manual cleaning is still required later, which is very troublesome. Utility Model Content

[0005] In order to overcome one of the shortcomings of the existing technology, the purpose of this utility model is to provide a fruit spraying machine that can effectively remove stains from the surface of the fruit and avoid mutual rubbing during the washing process.

[0006] To solve the above problems, the technical solution adopted by this utility model is as follows:

[0007] A fruit washing machine includes a mesh conveyor belt, an ultrasonic soaking tank, a high-pressure rinsing device, and a drying device.

[0026] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain this utility model and are not intended to limit this utility model.

[0027] Reference Figures 1 to 4 The fruit washing machine shown includes a mesh conveyor belt 10, an ultrasonic soaking tank 20, a high-pressure rinsing device 30, and a drying device 40. One end of the ultrasonic soaking tank 20 is connected to the input end of the mesh conveyor belt 10 via a chain conveyor belt 50. Several water-spraying actuators 21 are provided on both sides of the ultrasonic soaking tank 20. An ultrasonic cleaning oscillator 22 is provided inside the ultrasonic soaking tank 20. The water flow sprayed by all the water-spraying actuators 21 has a spatial component that faces the input end of the chain conveyor belt 50. The output end of the mesh conveyor belt 10 passes through the high-pressure rinsing device 30 and the drying device 40 in sequence.

[0028] Both the mesh conveyor belt 10 and the chain plate conveyor belt 50 are conventional transmission structures, which will not be described in detail here. In this application, the high-pressure rinsing device 30 can adopt the structure in patent CN202321502923.8 - A Dragon Fruit Washing Equipment, and the drying device 40 can be a conventional hot air drying method. In this application, the water-flushing actuator 21 is actually a spray pipe. The water flow sprayed from the spray pipe pushes the floating fruit in the ultrasonic soaking tank 20, causing these fruit to flow to the feed end of the chain plate conveyor belt 50 and be carried forward by the chain plate conveyor belt 50.

[0029] This fruit washing machine uses an ultrasonic soaking tank 20 to soak the harvested fruit, facilitating subsequent cleaning. Soaking helps dissolve surface stains and reduces overall stickiness, making secondary cleaning easier. Ultrasonic waves in the ultrasonic soaking tank 20 clean the fruit surface, improving cleaning efficiency and effectiveness. A water-pumping device 21 transports the fruit within the ultrasonic soaking tank 20, preventing damage from mechanical transport and protecting the fruit. A high-pressure rinsing device 30 performs a second rinse, effectively removing stubborn stains and residual wastewater, ensuring cleanliness. Finally, a drying device 40 dries the fruit, aiding in preservation and preventing spoilage caused by residual water.

[0030] See Figures 1 to 3 In one embodiment of this application, for better rinsing, the high-pressure rinsing device 30 includes a frame 31, a water tank 32 mounted on the frame 31, and a protective cover 33. The protective cover 33 is positioned above the water tank 32, forming a passageway between them. The mesh conveyor belt 10 passes through the passageway. Spray pipes 34 are provided on the inner wall of the protective cover 33 and above the water tank 32 in the circumferential direction of the passageway. Several nozzles 35 are provided on the spray pipes 34, and all the nozzles 35 face the mesh conveyor belt 10. A water supply mechanism is provided inside the water tank 32, and the water supply mechanism is connected to the spray pipes 34.

[0031] In the above embodiment, the protective cover 33 can be opened relative to the water tank 32, facilitating later maintenance. The protective cover 33 is made of a transparent material, such as acrylic sheet, allowing staff to easily view the interior. The spray pipe 34 has a portion that is ring-shaped and fitted around the mesh conveyor belt 10, allowing for comprehensive rinsing of the fruit conveyed on the mesh conveyor belt 10. Furthermore, in the above embodiment, the water tank 32 is used for water supply, while the water sprayed from the nozzle 35 falls directly back into the water tank 32, thus achieving water recycling.

[0032] In the above embodiments, to facilitate water supply, the water supply mechanism includes an inlet pipe 36 and a water pump 37 installed on the inlet pipe 36. One end of the inlet pipe 36 is connected to the spray pipe 34. Furthermore, to prevent particulate impurities from entering the water in the water tank 32, a filter head 38 is installed at the inlet end of the inlet pipe 36, thus preventing impurities in the water from clogging the spray nozzle 35.

[0033] See Figure 3 In the above-described improved embodiment, to better recycle wastewater, a funnel-shaped collecting plate 39 is provided at one end of the water tank 32 with an opening. The collecting plate 39 divides the water tank 32 into a water collection chamber 3a and a confluence chamber 3b. The confluence chamber 3b is located above the water collection chamber 3a. The inlet end of the water supply mechanism is connected to the water collection chamber 3a. The protective cover 33 is fastened above the confluence chamber 3b and forms the passageway. An installation opening 3c is provided at the lowest point of the collecting plate 39. The installation opening 3c connects the water collection chamber 3a and the confluence chamber 3b. A filter box 3d is provided on the installation opening 3c, and a filter element 3e is provided inside the filter box 3d. The water sprayed by the nozzle 35 washes the fruit and then flows into the collecting plate 39. This wastewater is filtered by the filter element 3e inside the filter box 3d and then re-enters the water collection chamber 3a to continue supplying water to the water supply mechanism, thus achieving recycling. The filter box 3d is designed to be detachable, which makes it easier to remove and replace the internal filter element 3e later.

[0034] In the above embodiment, in order to facilitate the later discharge of sewage from the water tank 32, the bottom of the water tank 32 is provided with a drain pipe that can be opened and closed. Of course, the water tank 32 is also connected to a water inlet pipe to facilitate the supply of water from an external water source to the water tank 32.

[0035] In an improved embodiment, to prevent stains from splashing during the spraying process, a baffle 3f is provided in the middle of the protective cover 33, which divides the protective cover 33 into two independent spaces, each of which is equipped with the spray pipe 34 and the nozzle 35. This dual-chamber design allows for staged spraying, minimizing cross-splashing of stains during the spraying process.

[0036] See Figure 3In one embodiment of this application, to allow the fruit to tumble and adapt to the rinsing of the nozzles 35 in various directions, and to avoid adjacent fruit pieces leaning too close together and creating cleaning dead zones, a plurality of roller brushes 3g are rotatably arranged inside the protective cover 33. All roller brushes 3g are located above the mesh conveyor belt 10, and all roller brushes 3g can cooperate with the mesh conveyor belt 10 to roll the fruit conveyed on the mesh conveyor belt 10 forward. The two ends of the roller brushes 3g are mounted on the inner wall structure of the protective cover 33 through elastic structures, such as springs. In this case, the roller brushes 3g can adjust their position according to the different sizes of the fruit pieces, adapting to different operating conditions. When the fruit pieces are conveyed forward with the mesh conveyor belt 10, the roller brushes 3g can cooperate with the mesh conveyor belt 10 to clamp the fruit pieces, causing the fruit pieces to shift forward or backward to adjust their position, facilitating the repositioning of the nozzles 35. Ideally, the roller brushes 3g should be positioned behind the output direction of the baffle curtain 3f.

[0037] See Figure 4 In one embodiment of this application, to better dry the water stains on the surface of the fruit, the drying device 40 includes a drying chamber 41 and a hot air blower 42 disposed at the bottom of the drying chamber 41. The drying chamber 41 has inlets and outlets on opposite sides, and curtains 43 are disposed on both inlets and outlets. The mesh conveyor belt 10 passes through the two inlets and outlets. Furthermore, the top of the drying chamber 41 is provided with an openable flip-top cover 43. This structural design facilitates subsequent maintenance and repair of the equipment inside the drying chamber 41.

[0038] The above embodiments are merely preferred embodiments of this utility model and should not be construed as limiting the scope of protection of this utility model. Any non-substantial changes and substitutions made by those skilled in the art based on this utility model shall fall within the scope of protection claimed by this utility model.
