[0052] The cleaning mechanism 3 includes a driving shaft 31 rotatably connected to the inner side of the first conveying frame 1, two first pulleys 32 are fixedly arranged on the surface of the driving shaft 31 and located on the inner side of the first conveying frame 1, two rotating brackets 33 are fixedly arranged at the bottom of the first conveying frame 1, and a cleaning brush roller 34 is rotatably connected to the opposite side of the two rotating brackets 33, and two second pulleys 35 are fixedly arranged on the surface of the cleaning brush roller 34, and the two first pulleys 32 and the second pulley 35 are divided into two groups, front and rear, and the surface of each group is sleeved with a first belt 36, and a driving motor 37 for driving the driving shaft 31 to rotate is arranged on the back of the first conveying frame 1;

[0053] Please combine Figure 3 : Start the driving motor 37, the driving motor 37 rotates to drive the driving shaft 31 and the two first pulleys 32 to rotate, the two first pulleys 32 drive the two second pulleys 35 to rotate through the first belt 36, the two second pulleys 35 rotate to drive the cleaning brush roller 34 to rotate, and the bottom of the first conveyor belt 22 is cleaned by the rotation of the cleaning brush roller 34;

[0054] Further, the driving motor 37 is started to rotate forward and reversely, and the driving motor 37 drives the cleaning brush roller 34 to rotate forward and reversely through the driving shaft 31, the first pulley 32, the first belt 36 and the second pulley 35. When one side of the rotten or deteriorated vegetable leaves is strongly adhered to the first conveyor belt 22, the cleaning brush roller 34 can clean the rotten or deteriorated vegetable leaves from the other direction, thereby improving the cleaning effect of the cleaning brush roller 34;

[0055] The detection mechanism 4 includes two first tooth plates 41 slidably connected to the inner side of the first conveying frame 1, two driving gears 42 are fixedly arranged on the surface of the driving shaft 31 and located on the outer side of the first conveying frame 1, and the two driving gears 42 are respectively meshed with the two first tooth plates 41, and a sliding frame 43 is fixedly arranged on the surface of the first tooth plate 41 on the front side, and a vertical plate 44 is vertically slidably connected to the inner side of the sliding frame 43, and a return spring 45 is fixedly arranged at the bottom of the inner wall of the sliding frame 43, and the top of the return spring 45 is fixedly connected to the bottom of the vertical plate 44, an industrial camera 46 is fixedly arranged on the back side of the top of the vertical plate 44, and a rotating wheel 47 is rotatably connected to the inner side of the top of the vertical plate 44, a supporting frame 48 is fixedly arranged on the top of the first conveying frame 1, and a trapezoidal plate 49 is fixedly arranged on the front side of the supporting frame 48;

[0056] Please combine Figure 5 and Figure 6: During the rotation of the driving shaft 31, the two driving gears 42 will be driven to rotate clockwise at the same time. The two driving gears 42 will rotate clockwise to drive the two first tooth plates 41 to move to the left. During the movement of the front first tooth plate 41 to the left, the sliding frame 43, the vertical plate 44, the rotating wheel 47 and the industrial camera 46 will be driven to move to the left at the same time. During the movement of the vertical plate 44 to the left, the rotating wheel 47 and the trapezoidal plate 49 are used in coordination, so that the vertical plate 44 drives the industrial camera 46 to move downward, and the reset spring 45 is contracted, and the industrial camera 46 moves to the lower left, so that the vegetables are tracked and detected while changing the detection direction, thereby improving the detection effect of the industrial camera 46 on vegetables;

[0057] Furthermore, when the industrial camera 46 moves to the left and completes the tracking and detection of the vegetables, the two driving gears 42 are driven to rotate counterclockwise by the reverse rotation of the driving shaft 31. The two driving gears 42 rotate counterclockwise and then drive the two first tooth plates 41 to move rightward. When the front first tooth plate 41 moves rightward, it will simultaneously drive the sliding frame 43, the vertical plate 44, the rotating wheel 47 and the industrial camera 46 to move rightward. Through the elastic force of the reset spring 45, the rotating wheel 47 will be close to the bottom of the trapezoidal plate 49 during the movement, so that the industrial camera 46 is reset to the upper right, so as to facilitate the detection of the next vegetable.

[0058] The scraping mechanism 5 comprises a connecting rod 51 fixed to the right side of the bottom of the two first tooth plates 41, the surfaces of the two connecting rods 51 are provided with arc-shaped scraping plates 52, and the surfaces of the two connecting rods 51 and the top and bottom of the arc-shaped scraping plates 52 are threadedly connected with locking nuts 53;

[0059] Please combine Figure 7 and Figure 8 : When the two first tooth plates 41 move to the left, the two connecting rods 51 will be driven to move to the left at the same time, and the arc scraper 52 will be driven to move to the left by the movement of the two connecting rods 51. When the vertical plate 44 drives the industrial camera 46 to the leftmost position, the arc scraper 52 will contact the cleaning brush roller 34. When the cleaning brush roller 34 rotates, the bottom of the first conveyor belt 22 and the surface of the arc scraper 52 will be cleaned at the same time, so as to avoid the accumulation of a lot of vegetable leaves on the surface of the arc scraper 52 and affect the cleaning effect of the first conveyor belt 22;

[0060] Furthermore, when the two first tooth plates 41 move to the right, the arc scraper 52 will be driven to move to the right at the same time through the two connecting rods 51, thereby resetting the position of the arc scraper 52;

[0061] Preferably, the arc scraper 52 has a scraping effect on the vegetable leaves stuck to the bottom of the first conveyor belt 22. By adjusting the position of the locking nut 53, the contact position between the top of the arc scraper 52 and the bottom of the first conveyor belt 22 can be adjusted, thereby improving the flexibility of the arc scraper 52 when in use.

[0062] A groove is provided on the inner side of the first conveying frame 1 for cooperating with the two first tooth plates 41 to allow the two first tooth plates 41 to slide left and right. The rotating wheel 47 is used in conjunction with the trapezoidal plate 49. When the vertical plate 44 moves to the left, the vertical plate 44 slides downward on the inner side of the sliding frame 43 under the cooperation of the rotating wheel 47 and the trapezoidal plate 49.

[0063] The curvature of the inner side of the arc-shaped scraper 52 is the same as the curvature of the outer surface of the cleaning brush roller 34 , and a through hole for use with the connecting rod 51 is provided on the inner side of the arc-shaped scraper 52 .

[0064] In this embodiment, unlike the existing pickle pretreatment conveying device, the present case drives the driving shaft 31 and the cleaning brush roller 34 to rotate forward and backward through the forward and reverse rotation of the driving motor 37, so that the vegetable leaves adhering to the surface of the first conveyor belt 22 can be cleaned from two different directions, thereby improving the cleaning effect of rotten or deteriorated vegetable leaves, and the clockwise rotation of the driving shaft 31 will drive the two first tooth plates 41 to move to the left through the driving gear 42, and the movement of the front first tooth plate 41 will drive the industrial camera 46 to move to the lower left, thereby tracking and detecting the vegetables and changing the detection position. The two first tooth plates 41 move to the left, which will drive the arc scraper 52 to move to the left through the two connecting rods 51. When the vertical plate 44 drives the industrial camera 46 to the leftmost position, the arc scraper 52 will come into contact with the cleaning brush roller 34, so as to not affect the cleaning effect of the arc scraper 52 on the first conveyor belt 22. At the same time, the cleaning brush roller 34 is used to clean the residual vegetable leaves on the surface of the arc scraper 52 without stopping the machine for manual cleaning, thereby improving the processing efficiency of pickles and the cleaning effect of rotten or spoiled vegetable leaves.

[0065] Second embodiment:

[0066] See also Figures 9 to 11, a material blocking mechanism 6 is slidably connected to the inner side of the first conveying frame 1, and the material blocking mechanism 6 includes a second tooth plate 61 slidably connected to the inner side of the first conveying frame 1, the second tooth plate 61 is meshed with the driving gear 42 on the front side, a first rotating seat 62 is fixedly provided on the right side of the top of the second tooth plate 61, a sliding seat 63 is fixedly provided on the top of the first conveying frame 1, a slide rail 64 is longitudinally slidably connected to the inner side of the sliding seat 63, a material blocking plate 65 is fixedly provided on the top of the slide rail 64, and a second rotating seat 66 is fixedly provided on the front side of the bottom of the slide rail 64, and a connecting rod 67 is rotatably connected to the surfaces of the first rotating seat 62 and the second rotating seat 66;

[0067] Please combine Fig. 9 and Fig.10 : When the driving shaft 31 drives the two driving gears 42 to rotate clockwise, the front driving gear 42 drives the second tooth plate 61 to move rightward, and the second tooth plate 61 moves rightward and then drives the slide rail 64 to slide backward on the inner side of the sliding seat 63 through the connecting rod 67, and the movement of the slide rail 64 drives the blocking plate 65 to block the vegetables, so that the vegetables stay in the same position for a short time, which is convenient for the staff to distinguish the quality of the vegetables with the naked eye, reduces the amount of neck activity of the staff, and thus reduces the fatigue of the staff, and the short stay of the vegetables gives the industrial camera 46 and the background processor enough time to distinguish the quality of the vegetables;

[0068] Furthermore, when the driving shaft 31 drives the two driving gears 42 to rotate counterclockwise, the front driving gear 42 will drive the second tooth plate 61 to move to the left. The second tooth plate 61 moves to the left and drives the slide rail 64 to slide forward on the inner side of the sliding seat 63 through the connecting rod 67, thereby resetting the position of the slide rail 64 and the material baffle plate 65, so that the vegetables continue to move to the left under the transmission of the first conveyor belt 22.

[0069] A flexible pushing mechanism 7 is fixedly arranged on the right side of the top of the first conveying frame 1, and the flexible pushing mechanism 7 includes a mounting bracket 71 fixedly arranged on the right side of the top of the first conveying frame 1, a hydraulic rod 72 is fixedly arranged on the top of the mounting bracket 71, a connecting plate 73 is fixedly arranged on the output end of the hydraulic rod 72, two guide rods 74 are fixedly arranged on the surface of the connecting plate 73, and pusher plates 75 are slidably connected to the surfaces of the two guide rods 74, and buffer springs 76 are sleeved on the surfaces of the two guide rods 74 and located in front of the pusher plates 75;

[0070] Please combine Fig.11: After the vegetables are inspected by the industrial camera 46, if the surface of the vegetables is rotten or the surface of the leaves is severely damaged, the background processor will issue a command to the hydraulic rod 72, and the hydraulic rod 72 will extend and drive the connecting plate 73 and the pushing plate 75 to move backward. The pushing plate 75 moves backward to push the vegetables that do not meet the inspection standards away from the first conveyor belt 22, and then the rotten or damaged leaves on the surface of the vegetables are manually removed. After removal, the qualified vegetables are placed on the top of the first conveyor belt 22, and the first conveyor belt 22 is used to transport the vegetables to the next work position.

[0071] In this embodiment, the driving shaft 31 and the driving gear 42 rotate clockwise to move the second tooth plate 61 to the right, and the slide rail 64 and the baffle plate 65 are driven to slide backward on the inner side of the sliding seat 63 under the action of the connecting rod 67, so that the vegetables stay in the same position for a short time, which is convenient for the staff to distinguish the quality of the vegetables with the naked eye, reduce the amount of neck activity of the staff, and thus reduce the fatigue of the staff. The short stay of the vegetables allows the industrial camera 46 and the background processor to have sufficient time to distinguish the quality of the vegetables. Vegetables that do not meet the inspection standards will be driven by the hydraulic rod 72 and pushed away from the first conveyor belt 22 by the push plate 75. After the rotten or damaged leaves on the surface are manually removed, the vegetables are transported to the next work position by the first conveyor belt 22.

[0074] Please combine Fig.12 : The rotation of the two second conveying rollers 82 can drive the second conveying belt 83 to rotate, and the setting of the protective seat 84 can prevent rotten or deteriorated vegetable leaves from separating from the second conveying belt 83 during the conveying process;

[0075] Preferably, the longitudinal width of the second conveyor belt 83 is greater than that of the first conveyor belt 22, so that when rotten or spoiled leaves fall from the first conveyor belt 22, they can accurately fall on the top of the second conveyor belt 83, facilitating the subsequent collection of the rotten or spoiled leaves.

[0076] A driving mechanism 9 is fixedly arranged at the front end of the first conveying roller 21 on the left side, and the driving mechanism 9 includes a third pulley 91 fixedly arranged at the front end of the first conveying roller 21 on the left side, a protective frame 92 is fixedly arranged on the left side of the front face of the second conveying frame 81, and the back side of the protective frame 92 is rotatably connected to two transmission gears 93, and the two transmission gears 93 are meshed with each other, and the back side of the bottom transmission gear 93 is fixedly connected to the front end of the second conveying roller 82 on the left side, and the back side of the top transmission gear 93 is fixedly arranged with a fourth pulley 94, and the surfaces of the third pulley 91 and the fourth pulley 94 are sleeved with a second belt 95;

[0079] Preferably, the workbench 10 is used to store unqualified vegetables. The staff will remove the rotten or spoiled leaves on the surface and throw them on the guide frame 11. The rotten or spoiled leaves will fall on the top of the second conveyor belt 83 after passing through the guide frame 11. The rotten or spoiled leaves transported by the second conveyor belt 83 will eventually fall into the collection box 12. Through the setting of the laser distance sensor 14, it can sense whether there are vegetables on the top of the first conveyor belt 22 to be transported to the left, thereby facilitating the control of the drive motor 37 to work.

[0080] In this embodiment, when the first conveyor belt 22 conveys vegetables to the left, the first conveyor roller 21 rotates counterclockwise to drive the third pulley 91 to rotate counterclockwise, and the third pulley 91 drives the fourth pulley 94 to rotate counterclockwise through the second belt 95. The fourth pulley 94 rotates in cooperation with the two transmission gears 93, causing the left second conveyor roller 82 to rotate clockwise, and then the second conveyor belt 83 is used to convey the rotten or spoiled leaves to the right, and the rotten or spoiled leaves are conveyed to the collection box 12.

[0081] Please refer to Figures 1 to 13 The working principle of the intelligent conveying device for pickle pretreatment provided by the present invention is as follows:

[0082] Step S1, firstly, place the vegetables on the right side of the top of the first conveyor belt 22, then start the conveying motor 23, the conveying motor 23 rotates to drive the first conveying roller 21 on the right side to rotate counterclockwise, the first conveying roller 21 on the right side rotates to drive the first conveyor belt 22 and the first conveying roller 21 on the left side to rotate, so as to transport the vegetables to the left side;

[0083] Step S2, starting the driving motor 37 to rotate forward and reversely, and the driving motor 37 drives the cleaning brush roller 34 to rotate forward and reversely through the driving shaft 31, the first pulley 32, the first belt 36 and the second pulley 35, and the bottom of the first conveyor belt 22 is cleaned by the forward and reverse rotation of the cleaning brush roller 34;

[0084] When the driving shaft 31 rotates clockwise, it drives the two driving gears 42 to rotate clockwise. The two driving gears 42 rotate clockwise and drive the two first tooth plates 41 to move to the left. When the front first tooth plate 41 moves to the left, it drives the sliding frame 43, the vertical plate 44, the rotating wheel 47 and the industrial camera 46 to move to the left. When the vertical plate 44 moves to the left, the rotating wheel 47 cooperates with the trapezoidal plate 49 to make the vertical plate 44 drive the industrial camera 46 to move downward, and the reset spring 45 contracts. The industrial camera 46 moves to the lower left, so that the vegetables are tracked and detected while changing the detection direction, thereby improving the detection effect of the industrial camera 46 on the vegetables;

[0085] When the two first tooth plates 41 move to the left, the two connecting rods 51 are driven to move to the left at the same time. The movement of the two connecting rods 51 drives the arc scraper 52 to move to the left. When the vertical plate 44 drives the industrial camera 46 to the leftmost position, the arc scraper 52 contacts the cleaning brush roller 34. When the cleaning brush roller 34 rotates, the bottom of the first conveyor belt 22 and the surface of the arc scraper 52 are cleaned at the same time.

[0086] Step S3, when the driving shaft 31 drives the two driving gears 42 to rotate clockwise, the front driving gear 42 drives the second tooth plate 61 to move rightward, and the second tooth plate 61 moves rightward and drives the slide rail 64 to slide backward inside the slide seat 63 through the connecting rod 67, and the movement of the slide rail 64 drives the blocking plate 65 to cover the vegetables, so that the vegetables stay in the same position for a short time, which is convenient for the staff to distinguish the quality of the vegetables by naked eyes, reduces the amount of neck activity of the staff, and thus reduces the fatigue of the staff;

[0087] When the driving shaft 31 drives the two driving gears 42 to rotate counterclockwise, the front driving gear 42 drives the second tooth plate 61 to move leftward, and the second tooth plate 61 moves leftward and drives the slide rail 64 to slide forward inside the slide seat 63 through the connecting rod 67, thereby resetting the positions of the slide rail 64 and the baffle plate 65, so that the vegetables continue to move leftward under the transmission of the first conveyor belt 22;

[0088] After the vegetables are inspected by the industrial camera 46, if the surface of the vegetables is rotten or the surface of the leaves is seriously damaged, the background processor will issue a command to the hydraulic rod 72, and the hydraulic rod 72 will extend and drive the connecting plate 73 and the push plate 75 to move backwards, and the vegetables that do not meet the inspection standards will be pushed away from the first conveyor belt 22 by the push plate 75 moving backwards, and then the rotten or damaged leaves on the surface of the vegetables will be manually removed, and after removal, the qualified vegetables will be put on the top of the first conveyor belt 22 again, and the first conveyor belt 22 will be used to transport the vegetables to the next working position;

[0089] Step S4, when the first conveyor belt 22 conveys vegetables to the left, the first conveyor roller 21 rotates counterclockwise to drive the third pulley 91 to rotate counterclockwise, and the third pulley 91 drives the fourth pulley 94 to rotate counterclockwise through the second belt 95. The fourth pulley 94 rotates in cooperation with the two transmission gears 93, so that the left second conveyor roller 82 rotates clockwise, and then the second conveyor belt 83 is used to convey the rotten or deteriorated vegetable leaves to the right;

[0090] After the staff removes the rotten or spoiled leaves on the surface of the vegetables on the workbench 10, they are thrown onto the guide frame 11. The rotten or spoiled leaves will fall on the top of the second conveyor belt 83 after passing through the guide frame 11. The leaves cleaned by the cleaning brush roller 34 and the arc scraper 52 will also fall on the top of the second conveyor belt 83 under the influence of gravity. The rotten or spoiled leaves are transported to the collection box 12 through the transportation of the second conveyor belt 83.
