Description

Technical Field

[0001] The invention relates to the technical field of fruit and vegetable cleaning equipment, in particular to a ring-type fruit and vegetable circulation cleaning device. Background Art

[0002] There are many types of fruit and vegetable cleaning machines on the market, and different types and models are used in different places. At present, fruit and vegetable cleaning machines mainly use high-pressure spray cleaning, bubble cleaning, drum friction cleaning, brush cleaning, ultrasonic cleaning and other methods.

[0003] Among them, high-pressure spray cleaning mainly relies on the force generated by the high-pressure water sprayed from the nozzle to remove the dirt attached to the surface of the vegetables. Brush cleaning is to brush off the dirt on the surface of the material by direct contact between the bristles and the material in the water. It is not suitable for cleaning some soft and easy to crack fruits and vegetables, and it is easy to damage the fruits and vegetables. The cleaning machines using other methods need to put the fruits and vegetables into the clean water of the machine body and then clean them in their own way. Since the fruits and vegetables are picked from the land or fruit trees, there is a lot of dirt or stains on their surfaces. Directly putting them into the machine body for cleaning will quickly pollute the cleaning water in the machine body. The cleaning water needs to be frequently replaced to ensure the subsequent good cleaning of the fruits and vegetables, which is not conducive to water saving. At the same time, replacing the cleaning water requires draining and then storing water, which takes a long time and affects the subsequent cleaning of fruits and vegetables.

The principle is the same as above and will not be repeated. This is repeated so that the cage net 32 ​​floats up and down while moving, and the fruits and vegetables are fully in contact with the cleaning water, thereby improving the cleaning effect; then the cage net 32 ​​moves to the rising station 11, the lower spur gear 23 meshes with the second lower long rack 17, the cage net 32 ​​rises through the partition 4, and moves from the immersion chamber 6 to the spray chamber 5.

After the cage net 32 ​​passes through the initial washing and lifting station 8, the first solenoid valve 50 is closed to achieve a water-saving effect. At the same time, the lower spur gear 23 meshes with the first lower long rack 13 and drives the first rotating shaft 20 to rotate. The lower spur gear 23 is always meshed with the driven spur gear 26, thereby driving the driven spur gear 26 and the screw 22 to rotate in the opposite direction. The nut block 29 converts the rotational motion of the screw 22 into a linear upward motion under the guidance of the sliding rod 30. The nut block 29 drives the cage net 32 ​​to rise through the mounting frame 31, so that the cage net 32 ​​passes through the partition 4 and enters the immersion chamber 6;

The nut block 29 drives the cage net 32 ​​to descend through the mounting frame 31, so that the cage net 32 ​​moves to the lowest point and is immersed in the cleaning water of the immersion chamber 6.

[0037] Then the cage net 32 ​​passes through the undulating station 10. The stroke of the undulating station 10 is long, which is convenient for fully cleaning the fruits and vegetables. At the undulating station 10, the lower spur gear 23 is meshed with the lower short rack 15, and the nut block 29 drives the cage net 32 ​​to descend. After the lower spur gear 23 is disengaged from the lower short rack 15, the upper spur gear 24 is meshed with the upper short rack 16, and the nut block 29 drives the cage net 32 ​​to rise. The principle is the same as above and will not be repeated. This is repeated so that the cage net 32 ​​floats up and down while moving, and the fruits and vegetables are fully in contact with the cleaning water, thereby improving the cleaning effect;

[0038] Subsequently, the cage net 32 ​​moves to the ascending station 11, the lower spur gear 23 meshes with the second lower long rack 17, the cage net 32 ​​rises through the partition 4, and moves from the immersion chamber 6 to the spray chamber 5; when moving to the final washing downward shifting station 12, the second proximity switch 55 detects that the cage net 32 ​​is approaching, the second water supply pipe 52 supplies water to the second spray pipe 53, and the second spray pipe 53 sprays washing water to the cage net 32, and the fruits and vegetables are finally washed to ensure the cleanliness of the fruits and vegetables. At the same time, the upper spur gear 24 meshes with the second upper long rack 18, the cage net 32 ​​descends, and after the cage net 32 ​​passes through the final washing downward shifting station 12, the second solenoid valve 54 is closed to save water; after the cage net 32 ​​passes through the final washing downward shifting station 12, it immediately moves to the fruit and vegetable access port 7, and the annular conveyor line 3 is controlled to pause by the controller 2.
