In order to avoid water accumulation inside the outer casing 1 , a plurality of drainage holes 21 are provided at the bottom of the outer casing 1 .

In order to realize that the main joint 7 and the auxiliary joint 8 can be connected after being docked, and can be closed separately after being separated; the main joint 7 and the auxiliary joint 8 are both one-way valves, and a push rod is fixed on the spool inside the one-way valve; The push rods of the main joint 7 and the auxiliary joint 8 are opposite.

In order to fully pour the fruits and vegetables in the filter frame 5 onto the material receiving plate 11 , the bottom of the filter frame 5 is inclined, and an extended rubber pad is installed on the end of the material receiving plate 11 inside the outer casing 1 .

For better cleaning, the main joint 7 of the E station is connected with a detergent box, and there is a certain pressure in the detergent box, and the pressure of the water inlet pipe is greater than the pressure in the detergent box. The main joint 7 of the bit is blocked by a plug.

In order to realize automatic cleaning, described control method is:

The first step: the auxiliary motor 18 is reversed, so that the water tank 6 is lowered to be out of contact with the filter frame 5, the filter frame 5 is drained, and the water falls into the water tank 6;

Step 2: The stepper motor rotates, so that the upper bracket 3 rotates 72 degrees counterclockwise, and the lower bracket 4 rotates 72 degrees clockwise at the same time, and the filter frame 5 and the water tank 6 are respectively fed to a station; at this time, it corresponds to the B station The fruits and vegetables in the filter frame 5 begin to fall.

Step 3: The auxiliary motor 18 is reversed to drive the water tank 6 down to the main joint 7 and the auxiliary joint 8 for docking; at this time, the water in the water tank 6 corresponding to the A station is emptied, and the water tank 6 corresponding to the B station filled with water;

Step 4: The auxiliary motor 18 rotates forward, drives the water tank 6 up to the maximum stroke, and puts it on the outside of the filter frame 5;

The fifth step: wait for soaking and add new fruits and vegetables in the hopper 9 .

In the present invention, the filter frame 5 is designed to be five, and it rotates counterclockwise. Starting from the A station, the one corresponding to the A station is responsible for feeding, and the one corresponding to the E station, D station, and C station is responsible for soaking. Cleaning and unloading corresponding to station B. Corresponding water tanks 6 are also designed to be five, rotating clockwise, with station A as the starting point, the one corresponding to station A is responsible for drainage, the one corresponding to station B is responsible for adding water, and the one corresponding to station C, station D, The corresponding station is responsible for soaking and cleaning; the C station, D station, and E station can all add cleaning agents, and the cleaning agents added by the three should not interact, that is, they are all acidic or alkaline. The brine can be added at will without any reaction.

Through the above design, it can be known that the fruits and vegetables are fed in a counterclockwise direction, while the water tank is fed in a clockwise direction. Fruits and vegetables are soaked and cleaned through three stations E, D, and C in sequence. The concentration of pesticide residues in the water tank 6 decreases successively from E, D, and C, and the C station is flushed with clear water.

Therefore, after the fruits and vegetables are continuously cleaned, they will first enter the water tank 6 corresponding to the E station for cleaning. The concentration of drug residues on the surface of strawberries and the content of dust are also relatively high. Through preliminary cleaning, the dust and pesticide residues on the surface of strawberries can be preliminarily cleaned. Then the water in station E will be turned to station A for emptying.

Then strawberry can enter D station to clean, and the content of water medicine residue and dust in the water tank 6 of D station is all less, and now strawberry is soaked for a certain period of time at D station, and most of them can be removed. Drug residues are removed.

Then the strawberries will enter the C station for cleaning. The water in the C station can further rinse and soak the small amount of pesticide residues left on the surface of the strawberries, so as to realize the thorough cleaning of the strawberries.

Finally, the strawberries after three-stage cleaning will fall at 10 outlets corresponding to station B.

The above is an illustration based on the running track of strawberries. The strawberries were cleaned three times respectively. At the same time, it is better to add cleaning agent at the E station. Water with high levels of pesticide residues is directly discarded.

Because it is difficult to completely remove pesticide residues in the traditional one-time cleaning, strawberries in this device will be washed three times, and the water quality is getting better and better, so as to achieve the final and thorough removal of pesticide residues.

Carry out another aspect explanation with the motion locus of water tank 6 below,

First of all, the clean water corresponding to station C will rinse the strawberries that have been washed twice, so the clean water at station C can ensure the least pesticide residue on the surface of the tank after washing; at the same time, the strawberries have been washed twice, so the strawberries at station C The water does not contain a high concentration of pesticide residues, so it can be fed to station D for a second rinse of strawberries that have been washed once; similarly, the water at station D has been used twice at this time, and the pesticide residue content It has been gradually improved, and finally the water in station D will be fed to station E, and the strawberries that have not been rinsed will be rinsed for the first time, and the floating ash, insect eggs, pesticide residues and other residues on the surface of strawberries will be washed, and station E can Add cleaning agent for more powerful flushing, and finally go to station A for emptying.

The water-saving embodiment of this device is generally a larger water tank 6 in the tradition, and the repeated cleaning requires a larger amount of water once. And this device adopts the mode of soaking in small batches, and the fruits and vegetables in the filter frame 5 have occupied a larger space, so only a small amount of water is needed in the water tank 6, and the water can fully immerse the fruits and vegetables.

And because it uses less water each time, it can continuously add clean water to achieve a method similar to running water washing, but it is also the purpose of interval cleaning, so as to obtain better cleaning and soaking effects.

This device uses small batches of water each time, so that the water can be replaced quickly, and then ensure that each batch of fruits and vegetables can be washed by clean water when cleaning, and at the same time, the recycling method is used to realize water reuse. The purpose of saving water and multi-stage cleaning is achieved, and the cleaning process is accelerated.

In this device, the fruits and vegetables rotate intermittently counterclockwise, in conjunction with the intermittent clockwise rotation of the water tank 6, in addition, the feeding and discharging of fruits and vegetables, as well as the water inlet and outlet of the water tank 6 are designed to realize fast multi-stage fruit and vegetable cleaning and avoid unnecessary water replacement. Timely impact on the cleaning effect, and at the same time, it can realize multi-stage cleaning, improve the cleaning effect and reduce the residue of pesticide residues.
