[0031] The embodiments of the present invention are described in detail below with reference to the accompanying drawings, but the present invention can be implemented in many different ways as defined and covered by the claims.

[0032] See also Figure 1 , Figure 3 As shown in Figure 5, a device for removing agricultural residues from fruits and vegetables comprises a base 1, a soaking frame 2, a cleaning component 3, a liquid outlet component 4, a liquid inlet component 5, a waste liquid frame 6 and a water supply component 7. The base 1 is placed on the ground, the upper end surface of the base 1 is fixedly connected to the soaking frame 2 through a support frame, the lower end surface of the soaking frame 2 is fixedly connected to the liquid outlet component 4, the cleaning component 3 is installed inside the soaking frame 2, the left end surface of the soaking frame 2 is fixedly connected to the liquid inlet component 5, the upper end surface of the base 1 is fixedly connected to the waste liquid frame 6, the waste liquid frame 6 is located below the soaking frame 2, and the right end surface of the soaking frame 2 is installed with the water supply component 7.

The lower end surface of the immersion frame 2 is fixedly connected to the rotating motor 31 through a motor seat. The output shaft of the rotating motor 31 passes through the lower end surface of the immersion frame 2 and is fixedly connected to the vertical shaft 32. The screen frame 33 is slidably connected to the vertical shaft 32. The outside of the vertical shaft 32 is located inside the screen frame 33 and is sleeved with a connecting sleeve 34. The connecting sleeve 34 is rotatably connected to the inner bottom surface of the screen frame 33. The outside of the vertical shaft 32 is located above the screen frame 33 and is sleeved with a screen cover plate 35. A plurality of clamping mechanisms 36 are installed between the screen cover plate 35 and the connecting sleeve 34. The front and rear ends of the cover plate are fixedly connected to the fixed end blocks 37. The front and rear side walls of the immersion frame 2 are fixedly connected to the clamping blocks 8, and the clamping blocks 8 are provided with end block grooves that match the fixed end blocks 37.

[0034] During the specific operation, the net cover plate 35 is first moved upward manually, and then the fruits and vegetables that need to be free of pesticide residues are placed inside the placement net frame 33. Then, the net cover plate 35 is moved downward and the clamping mechanism 36 is used to clamp the net cover plate 35 on the upper end surface of the connecting sleeve 34. The external mobile device moves the placement net frame 33 down to the bottom of the immersion frame 2. During the downward movement, the fixed end blocks 37 at both ends of the net cover plate 35 just move into the end block grooves of the clamping blocks 8. When the water supply component 7 completes the internal water supply and the liquid inlet component 5 completes the addition of the purifier, the rotating motor 31 is manually started, and the output shaft of the rotating motor 31 drives the vertical shaft 32 to rotate, and the vertical shaft 32 drives the placement net frame 33 to rotate. Because the end block groove limits the fixed end block 37, the net cover plate 35 is stationary, and the connecting sleeve 34 is further stationary, thereby achieving the cleaning of the internal fruits and vegetables.

[0035] See also Figure 3 The outer surface of the connecting sleeve 34 is provided with a No. 1 brush, and the inner side surface of the screen frame 33 is provided with a No. 2 brush.

[0036] During specific operation, when the cleaning component 3 rotates to clean, the No. 2 brush rotates, while the No. 1 brush remains stationary, so that there is a displacement difference between the two brushes, thereby achieving all-round scrubbing of the internal fruits and vegetables.

[0037] See also Figure 4 The clamping mechanism 36 includes a diamond groove 361, a loading plate 362, a No. 1 clamping plate 363, a No. 2 clamping plate 364 and a support spring 365. The upper end surface of the connecting sleeve 34 is evenly provided with a plurality of diamond grooves 361 along its circumferential direction. The lower end surface of the mesh cover plate 35 is fixedly connected with a plurality of loading plates 362 corresponding to the positions of the diamond grooves 361. The lower end surface of the loading plate 362 is hingedly connected to the No. 1 clamping plate 363 on one side close to the vertical axis 32 and on the side away from the vertical axis 32. The two No. 1 clamping plates 363 are symmetrically arranged. The lower end of each No. 1 clamping plate 363 is provided with a No. 2 clamping plate 364 by a hinge connection. The two No. 2 clamping plates 364 are hingedly connected on the side away from the No. 1 clamping plate 363. A support spring 365 is arranged between one end of the No. 1 clamping plate 363 close to the loading plate 362 and the lower end surface of the loading plate 362.

[0038] During specific operation, when the mesh cover plate 35 needs to be clamped on the connecting sleeve 34, first align the mesh cover plate 35 with the connecting sleeve 34, and then press the two No. 1 clamping plates 363 against the upper end surface of the diamond groove 361. During this process, the diamond groove 361 applies an extrusion force to the No. 1 clamping plate 363 and the No. 2 clamping plate 364 and increases the angle of their connection, the support spring 365 is extended, and then the mesh cover plate 35 continues to be pressed downward and the No. 1 clamping plate 363 and the No. 2 clamping plate 364 are squeezed into the diamond groove 361. At this time, the No. 1 clamping plate 363 and the No. 2 clamping plate 364 are reset and abutted against the inner wall of the diamond groove 361 under the action of the support spring 365, thereby realizing multi-directional fixation between the mesh cover plate 35 and the connecting sleeve 34, and the mesh cover plate 35 can be quickly removed from the connecting sleeve 34, so as to facilitate the removal and placement of fruits and vegetables inside.

[0039] See also Figure 3 , Figure 6 and Figure 7 The liquid inlet assembly 5 includes a liquid storage tank 51, a rotating shaft 52, a liquid inlet wheel 53, a ratchet 54, a gear ring 55, a pawl 56, a rack 57, a linkage rod 58 and a float 59. The left end surface of the immersion frame 2 is fixedly connected with the liquid storage tank 51. The bottom surface of the liquid storage tank 51 is provided with an arc groove, and a liquid inlet hole is provided in the arc groove. The liquid inlet hole is communicated with the inside of the immersion frame 2. The left end of the liquid storage tank 51 is provided with a rotating hole, and the rotating hole is rotatably connected with the rotating shaft 52. The left end of the rotating shaft 52 is fixedly connected with the liquid inlet wheel 53. The liquid inlet wheel 53 rotates along its A plurality of liquid storage tanks are evenly arranged on the annular surface, the right end of the rotating shaft 52 passes through the left side wall of the immersion frame 2 and is fixedly connected to a ratchet 54, a gear ring 55 is rotatably connected to the left inner wall of the immersion frame 2, the gear ring 55 is sleeved on the outside of the ratchet 54, a plurality of ratchet pawls 56 are rotatably connected to the inner surface of the gear ring 55, a rack 57 is meshed at the rear end of the gear ring 55, a connecting rod 58 is fixedly connected to the rear end face of the rack 57, the connecting rod 58 is slidably connected to the left inner wall of the immersion frame 2, a buoy 59 is fixedly connected to the bottom of the right end face of the connecting rod 58.

[0040] In specific operation, when the water level inside the immersion frame 2 rises, the water level drives the buoy 59 to rise, and the buoy 59 drives the linkage rod 58 to move upward, further driving the rack 57 to move upward, and the rack 57 drives the gear ring 55 to rotate, and the gear ring 55 drives multiple pawls 56 to rotate at the same time. At this time, the pawls 56 abut against the radial surface of the ratchet 54, so that the pawls 56 can drive the ratchet 54 to rotate, and then the ratchet drives the rotating shaft 52 and the liquid inlet wheel 53 to rotate. During the rotation process, the liquid storage tank on the liquid inlet wheel 53 will The purifier is filled and rotated to the inside of the arc groove, and then when it rotates to the liquid inlet hole, the purifier inside the liquid storage tank flows into the inside of the immersion frame 2 through the liquid inlet hole, thereby realizing the control of the added amount of the purifier by the rise of the water level. When the water level inside the immersion frame 2 drops, the buoy 59 drives the connecting rod 58 to drop, causing the gear ring 55 to rotate in the opposite direction. At this time, the pawl 56 will slide on the tooth slope of the ratchet 54 without driving the ratchet 54 to rotate, thereby ensuring that the purifier will not be added to the immersion frame 2 when the liquid is discharged.

[0041] See also Figure 5 The liquid outlet assembly 4 includes a connecting block 41, a piston column 42, a threaded rod 43, a limit rod 44, a telescopic spring 45, an adjusting rod 46 and a pull ring 47. The lower end surface of the immersion frame 2 is fixedly connected with the connecting block 41, and the lower end surface of the immersion frame 2 is provided with a piston hole. The upper end surface of the connecting block 41 is provided with a sliding groove at a position corresponding to the liquid outlet hole. The piston column 42 is slidably connected in the piston hole. The piston column 42 is provided with an inclined liquid outlet hole. The left end surface of the sliding groove is provided with a circulation pipeline. The lower end surface of the piston column 42 is rotatably connected with the threaded rod 4 3. The threaded rod 43 penetrates through and is threadedly connected to the lower end surface of the connecting block 41. A limiting hole is provided on the right end surface of the piston column 42. A storage hole is provided at a position corresponding to the limiting hole on the right end surface of the sliding groove. A limiting rod 44 is slidably connected in the storage hole. A telescopic spring 45 is fixedly connected between the left end of the limiting rod 44 and the inside of the storage hole. An adjusting rod 46 is passed through the inside of the telescopic spring 45. The left end of the adjusting rod 46 is fixedly connected to the right end surface of the limiting rod 44. The right end of the adjusting rod 46 penetrates through the right end surface of the connecting block 41 and is fixedly connected to a pull ring 47.

[0042] During specific work, when it is necessary to open the liquid outlet component 4, the pull ring 47 is manually pulled, and the pull ring 47 drives the adjusting rod 46 to move to the left so that the limiting rod 44 exits the limiting hole. At this time, the telescopic spring 45 is compressed, and then the threaded rod 43 is manually rotated to further drive the piston column 42 to move downward. During the downward movement, the pull ring 47 is released, and the liquid outlet hole on the piston column 42 connects the inside of the immersion frame 2 with the circulation pipeline, so that the internal waste liquid is discharged. When the waste liquid is completely discharged, the threaded rod 43 is rotated in the opposite direction to make the piston column 42 move upward. When it returns to its original position, the telescopic spring 45 extends out to drive the limiting rod 44 to enter the limiting hole, thereby realizing the limiting fixation of the piston column 42.

[0043] See also Figure 3 The water supply assembly 7 includes a water inlet hole 71 and a flushing nozzle 72. The right end surface of the immersion frame 2 is provided with a water inlet hole 71. A flushing nozzle 72 is fixedly connected to the corresponding position of the water inlet hole 71 inside the immersion frame 2. The inside of the flushing nozzle 72 is connected to the water inlet hole 71.

[0044] During specific work, after the liquid is discharged, an external mobile device is used to raise the cleaning component 3 to the top of the inside of the immersion frame 2. At this time, the mesh frame 33 is placed just at the flushing nozzle 72. At this time, the rotating motor 31 is started and the external water supply is turned on. The mesh frame 33 drives the internal fruits and vegetables to rotate while the flushing nozzle 72 flushes the internal fruits and vegetables to remove the cleaning waste liquid remaining on the surface of the fruits and vegetables. The flushing water will remain in the immersion frame 2 and drive the liquid inlet component 5 to add a purifier to prepare for the next batch of fruits and vegetables to remove agricultural residues. If it is the last batch of fruits and vegetables to remove agricultural residues, it can be flushed with the liquid outlet component 4 opened to avoid waste of purifiers.

[0045] In addition, the present invention also provides a method for removing pesticide residues from fruits and vegetables, and the specific method steps are as follows: S1: first, manually move the net cover plate 35 upward and then put the fruits and vegetables that need to remove pesticide residues into the inside of the placement net frame 33, then move the net cover plate 35 downward and use the clamping mechanism 36 to clamp the net cover plate 35 on the upper end surface of the connecting sleeve 34, and use an external mobile device to move the placement net frame 33 downward to the bottom of the inside of the soaking frame 2. During the downward movement, the fixed end blocks 37 at both ends of the net cover plate 35 just move into the end block grooves of the clamping block 8.

[0046] S2: Use the water supply component 7 to supply water to the immersion frame 2. When the water level inside the immersion frame 2 rises, the water surface drives the buoy 59 to rise, and the buoy 59 drives the connecting rod 58 to move upward, further driving the rack 57 to move upward, and the rack 57 drives the ring gear 55 to rotate, and the ring gear 55 simultaneously drives multiple pawls 56 to rotate. At this time, the pawl 56 abuts against the radial surface of the ratchet 54, so that the pawl 56 can drive the ratchet 54 to rotate, and then the ratchet drives the rotating shaft 52 and the liquid inlet wheel 53 to rotate. During the rotation process, the liquid storage tank on the liquid inlet wheel 53 will be filled with the purifier and rotate to the inside of the arc groove. Then, when it rotates to the liquid inlet hole, the purifier inside the liquid storage tank flows into the immersion frame 2 through the liquid inlet hole, thereby realizing the control of the additive amount of the purifier by the water surface rising amplitude. When the water level inside the immersion frame 2 drops, the buoy 59 drives the connecting rod 58 to drop, so that the ring gear 55 rotates in the opposite direction. At this time, the pawl 56 will slide on the tooth inclined surface of the ratchet 54 and will not drive the ratchet 54 to rotate.

[0047] S3: Manually start the rotating motor 31, the output shaft of the rotating motor 31 drives the vertical shaft 32 to rotate, and the vertical shaft 32 drives the placement net frame 33 to rotate. Because the end block groove limits the fixed end block 37, the net cover plate 35 is stationary, and the connecting sleeve 34 is further stationary, so as to achieve the cleaning of the internal fruits and vegetables. Manually pull the pull ring 47, the pull ring 47 drives the adjustment rod 46 to move leftward so that the limit rod 44 exits the limit hole, at this time the telescopic spring 45 is compressed, and then the threaded rod 43 is manually rotated to further drive the piston column 42 to move downward. During the downward movement, the pull ring 47 is released, and the liquid outlet hole on the piston column 42 connects the inside of the soaking frame 2 with the circulation pipeline, so that the internal waste liquid is discharged. When the waste liquid is completely discharged, the threaded rod 43 is rotated in the opposite direction to make the piston column 42 move upward. When it returns to the initial position, the telescopic spring 45 extends to drive the limit rod 44 into the limit hole, so as to achieve the limit fixation of the piston column 42, and then the external mobile device lifts the cleaning component 3 to the top of the inside of the soaking frame 2.

[0048] S4: At this time, the rotating motor 31 is started and the external water supply is turned on. The net frame 33 is placed to drive the internal fruits and vegetables to rotate while the flushing nozzle 72 flushes the internal fruits and vegetables to remove the residual cleaning waste liquid on the surface of the fruits and vegetables. The flushing water will remain in the soaking frame 2 and drive the liquid inlet component 5 to add a purifier to prepare for the next batch of fruits and vegetables to remove agricultural residues.

[0049] S5: Take out the fruits and vegetables that have been cleaned of pesticide residues in the cleaning component 3, and then put in the fruits and vegetables that need to be cleaned of pesticide residues later. The external mobile device moves the cleaning component 3 down to the bottom of the soaking frame 2 and repeats steps S3, S4 and S5.
