[0032] Below, the embodiments of the utility model are described in detail with reference to the accompanying drawings.

[0033] Example

[0034] Please refer to Figure 1 , a continuous fruit and vegetable washing device provided in this embodiment includes a rough washing system, a fine washing system, a soaking system, a draining system, a conveying line and a control system 19;

[0035] The rough washing system includes a washing tank 1, inside which a bubbling washing machine is installed; the bubbling washing machine is connected in sequence to a circulation pump 2 and a filter 3, and the washing tank 1, the circulation pump 2 and the filter 3 are connected in sequence to form a circulation loop; a sewage pipe 6 is connected to the bottom of the washing tank 1 for discharging sewage and sediment generated during the cleaning process.

[0036] When the rough washing system is working, the fruits and vegetables in the washing box 1 are roughly washed by the bubbling washing machine, and the circulating pump 2 extracts the sewage in the washing box 1, and the sewage is filtered by the filter 3 and then transported back to the washing box 1. The sediment deposited in the washing box 1 can be discharged through the sewage pipe 6, and a valve is provided on the sewage pipe 6. When the sediment in the washing box 1 needs to be discharged, the valve can be opened, and the valve can be closed after the discharge is completed. The valve can also be an electronically controlled valve, connected to the control system 19, and the control system 19 controls the switch.

[0037] In this embodiment, 4 first scrapers are provided on the bubbling cleaning machine, and the structure of the first scraper 4 adopts existing product technology. The first scraper 4 is made of a flexible and elastic rubber material, and is in a long strip shape as a whole. The width of the first scraper 4 is slightly larger than the width of the conveyor belt 8, and the thickness is moderate to ensure sufficient strength and flexibility. The front end of the first scraper 4 is designed to be thin and smooth to facilitate scraping of vegetables. The back of the first scraper 4 is connected to a horizontally movable slide rail through a plurality of evenly distributed metal brackets. The slide rail is arranged on the conveying bracket 7 and can move along the conveying bracket 7 driven by the motor. The slide rail is driven by a motor, and precise linear motion is achieved through transmission methods such as gear racks or lead screw nuts.

[0038] When the vegetables on the conveyor belt 8 reach the predetermined position, the motor starts, and the driving rail drives the first scraper 4 to move horizontally. Since the front end of the first scraper is in close contact with the surface of the conveyor belt 8, the vegetables are gradually scraped off the conveyor belt 8 during the movement of the first scraper 4, and placed in the cleaning box 1. After the scraping is completed, the motor reverses, so that the first scraper 4 returns to the initial position, ready for the next scraping operation.

[0039] The fine washing system includes a spray frame 10, on which a plurality of spray heads are arranged; a water collection tank is located below the spray frame 10, and the spray frame 10 is arranged above the water collection tank, which is in the washing tank, so that the spray heads can be aimed at the fruits and vegetables transported from the rough washing system; the spray frame 10 is connected with a plurality of water pipes, and the spray frame 10 is in the shape of a frame as a whole, and the spray heads are connected with the water pipes; the spray frame 10 is provided with a water inlet, which is connected with a water pump 11 through a water pipe, and the water pump 11 is fixedly installed in the equipment cavity 12, and the water pump 11 is connected with a clean water tank, which can be connected with a water supply device, and the water pump 11 is connected with a control system 19. When the conveyor belt 8 passes through the spray frame 10, the direction of the conveyor belt 8 is changed by the redirecting wheel installed on the conveying bracket 7, so that the fruits and vegetables on the conveyor belt 8 can be better cleaned.

[0040] When the fine washing system is working, the water pump 11 is started, clean water is pumped out from the clean water tank, and the fruits and vegetables that have been roughly washed are rinsed through the nozzles on the spray frame 10, and the fruits and vegetables are finely washed. The water after spraying and washing the fruits and vegetables falls into the water collection tank and is discharged through the water collection tank.

[0041] An ozone sterilization device is installed above the water collection tank, which can clean and sterilize at the same time.

[0042] The cleaning equipment is equipped with a circulating water device, and the water tank is filled with circulating water. The circulating water device includes a pump, which is connected to the water collection tank, filter, and clean water tank through pipelines. The pump draws water from the water collection tank, filters it through the filter, and then delivers it to the clean water tank.

[0043] The soaking system includes a soaking water tank 15 for soaking fruits and vegetables. The soaking water tank 15 is filled with preservative solutions of different concentrations according to different vegetables. The soaking water tank 15 is a cylindrical water tank. The staff prepares CaCl2 solutions of appropriate concentrations according to different vegetables in advance and puts them into the soaking water tank 15. A drain plate 20 is arranged at the bottom of the soaking water tank 15. The drain plate 20 is connected to a lifting mechanism. The lifting mechanism is connected to the control system 19. The lifting mechanism is an existing technology and can drive the drain plate 20 to rise and fall in the soaking water tank 15. A drain port is arranged at the bottom of the soaking water tank 15. The drain port is provided with a valve, and the valve is connected to the control system 19.

[0044] After the fruits and vegetables are sent to the soaking water tank 15, the fruits and vegetables are soaked in the soaking water tank 15 for a set time, and the control system 19 controls the drain plate 20 to rise, and the fruits and vegetables are sent to the conveyor belt 8 of the conveyor line.

[0045] The drain plate 20 is tilted as a whole, forming a certain angle with the horizontal direction. A plurality of vibrators are installed at the bottom of the drain plate 20, and the vibrators are connected to the control system 19. When the draining is completed and the fruits and vegetables need to be dumped onto the conveyor belt, the vibrators are started to make the drain plate 20 vibrate at a high frequency. The surface of the drain plate 20 is designed with fine drainage grooves to facilitate drainage. At the same time, the surface adopts an anti-slip texture to prevent the fruits and vegetables from sliding excessively during the vibration process. At one end of the drain plate 20 close to the conveyor belt, a downwardly inclined transition section is set. The edge of the transition section adopts an arc design to reduce the collision damage of fruits and vegetables during movement. Due to the vibration and tilt angle of the drain plate 20, the fruits and vegetables will gradually move to the transition section under the action of vibration, and finally slide through the transition section onto the conveyor belt.

[0046] The soaking water tank 15 is a cylindrical water tank with a smooth inner surface, which can prevent mechanical damage to fruits and vegetables caused by collision during the soaking process. The soaking time is controlled by the control system 19, and it is easy to use.

[0047] The draining system includes two rows of air-drying drainers 17, which are conventional products and are used to dry washed fruits and vegetables. The air-drying drainer 17 is connected to a fan, which is connected to a control system 19 and has multiple air outlets. The wind force of the fan is controlled by the control system 19.

[0048] The air-drying drainer has the function of swinging direction, which can expand the blowing direction of the wind and further avoid the loss of moisture in vegetables caused by air drying.

[0049] The fruit and vegetable continuous cleaning device of this embodiment is provided with a radiator 21, which can release the excess heat of the device and protect the machine.

[0050] The conveying line passes through the rough washing system, the fine washing system, the soaking system and the draining system in sequence; the control system is connected with the rough washing system, the fine washing system, the soaking system, the draining system and the conveying line.

[0051] The conveyor line includes a conveyor bracket 7, a drive motor 16 and a conveyor belt 8. Part of the conveyor bracket 7 is arranged in the cleaning box 1, the drive motor 16 is arranged on one side of the upper part of the conveyor bracket, and the conveyor belt 8 is arranged between the conveyor brackets. The drive motor 16 drives the conveyor belt 8 to rotate through the transmission mechanism. The control system 19 sends a signal to the drive motor 16 to control its start, stop and speed regulation. The drive motor 16 directly drives the conveyor belt 8 to make it run continuously and drive the vegetables to move.

[0052] The conveyor belt emergency brake 5 is installed under the conveying bracket 7; the drive motor 16 is fixedly installed on the top side of the conveying bracket. The drive motor 16 is connected to the control system 19, and the control system 19 is used to set the start and stop of the conveyor belt 8.

[0053] Since a large amount of water vapor and water splashes will be generated during the fruit and vegetable washing process, placing the drive motor 16 and the conveying bracket 7 at a relatively large distance can effectively reduce the erosion of the motor by water vapor, reduce the risk of motor failure, and increase its service life and operational stability. During assembly line operation, the vibration frequency and amplitude of each link may be different. A relatively large distance can prevent the vibration of the conveying bracket 7 from being directly transmitted to the drive motor 16, thereby reducing the impact on the motor performance and ensuring the accuracy and stability of its output power. At the same time, considering the possible subsequent upgrades and modifications of the assembly line, a large space is reserved to facilitate the addition of new components or adjustment of the existing structure, and the distance between the conveying bracket 7 and the drive motor 16 provides such flexibility.

[0054] A plurality of material baffles 18 are evenly spaced on the conveyor belt 8 to minimize mechanical damage caused by collision of vegetables. The fruits and vegetables can be taken out of the washing box 1 and transported to the fine washing system through the material baffles 18.

[0055] The second scraper 14 is arranged on the conveying bracket 7 at the fine washing system. The second scraper 14 adopts the same structure as the first scraper 4. The structure of the second scraper 14 adopts the existing product technology. When the vegetables on the conveyor belt 8 reach the predetermined position, the motor starts, and the driving rail drives the second scraper 14 to move horizontally. Since the front end of the second scraper 14 is in close contact with the surface of the conveyor belt 8, during the movement of the second scraper 14, the vegetables are gradually scraped off the conveyor belt 8 and placed in the washing pool. After the scraping is completed, the motor reverses to return the scraper to the initial position to prepare for the next scraping operation.

[0056] When the fruit and vegetable continuous cleaning device of this embodiment is working, first place the vegetables on the conveyor belt 8 at the right end of the cleaning device, turn on the control system 19, and the cleaning device starts working. The vegetables will enter the cleaning box 1 along the conveyor belt 8, turn on the circulating water pump 2 of the bubbling cleaning machine, and generate bubbles by the circulating water pump 2. The control system 19 can adjust the running speed of the conveyor belt 8 according to the different settings of the vegetable types to ensure the residence time of the vegetables in the water. In this process, the vegetables are washed multiple times by bubbling, spraying, surfing, etc. After rough washing, the vegetables automatically enter the fine washing system along the conveyor belt 8, turn on the water pump 11 and the spray frame 10, and an ozone sterilization device 13 is installed above the water collection tank, so that the vegetables can be washed and sterilized at the same time. The clean water tank is connected to a water circulation filter, which filters water more thoroughly and saves more water. The washed vegetables are placed along the conveyor belt 8 into the cylindrical soaking water tank 15 to be soaked in CaCl2 solution. The soaking time is controlled by the control system 19. After soaking, the soaking water tank 15 will automatically drain the water, and the drain plate 20 at the bottom will automatically rise to send the vegetables to the conveyor belt 8 and enter the draining system. The wind force of the draining system is controlled by the control system 19. Material baffles 18 are installed at equal intervals on the conveyor belt 8 to minimize mechanical damage caused by collision of vegetables. The air-dried vegetables are removed along the conveyor belt.

[0057] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the utility model, rather than to limit it. Although the utility model has been described in detail with reference to the aforementioned embodiments, those skilled in the art should understand that they can still modify the technical solutions described in the aforementioned embodiments, or make equivalent replacements for some of the technical features therein.
