Description

Technical Field

[0001] The present invention relates to the technical field of agricultural product processing and transportation, and particularly to an intelligent conveying device for pickled vegetable pretreatment processing. Background Art

[0002] Pickled vegetables are a kind of food that has been pickled and marinated, famous for its unique flavor and long preservation time, and widely distributed throughout the country. The pretreatment processing of pickled vegetables is a key step to ensure the quality and taste of pickled vegetables, specifically including steps such as raw material selection, cleaning, cutting, pickling, and marinating. These steps together ensure the high-quality production of pickled vegetables. In the production workshop, to ensure the smooth transfer of materials between steps, a conveying device is needed to transport the materials.

[0003] In the related art, the vegetables used to make pickled vegetables generate heat during freight transportation. Coupled with the action of bacterial decomposition and protease, the vegetables will deteriorate or the leaves will rot, so the vegetables need to be selected before making pickled vegetables. When the existing conveying device conveys and selects vegetables, some deteriorated or rotten vegetable leaves will stick to the conveyor belt or the cleaning scraper due to the water on their surfaces, which is very inconvenient to clean. In necessary cases, it is necessary to stop the machine for manual cleaning, which will affect the processing efficiency of pickled vegetables, and the vegetable leaves sticking to the surface of the conveyor belt may affect the sorting and rejection effect of the device on vegetables.

[0004] Therefore, it is necessary to provide an intelligent conveying device for pickled vegetable pretreatment processing to solve the above technical problems. Summary of the Invention

[0046] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention

[0047] The present invention provides an intelligent conveying device for pickled vegetable pretreatment processing

[0048] First embodiment

[0049] Please refer to Figures 1 to 8 , an intelligent conveying device for pickled vegetable pretreatment processing, including a first conveying frame 1, a first conveying mechanism 2, a cleaning mechanism 3, a detection mechanism 4 and a scraping mechanism 5

[0050] The first conveying mechanism 2 includes two first conveying rollers 21 rotatably connected to the inner side of the first conveying frame 1. A first conveyor belt 22 is sleeved on the surfaces of the two first conveying rollers 21. A conveying motor 23 for driving the right first conveying roller 21 to rotate is arranged on the right side of the back surface of the first conveying frame 1

[0051] Please combine Figure 2 and Figure 3 : Start the conveying motor 23. The rotation of the conveying motor 23 drives the right first conveying roller 21 to rotate. The rotation of the right first conveying roller 21 further drives the first conveyor belt 22 and the left first conveying roller 21 to rotate

[0052] The cleaning mechanism 3 includes a drive shaft 31 rotatably connected to the inside of the first conveyor frame 1. On the surface of the drive shaft 31 and inside the first conveyor frame 1, two first belt pulleys 32 are fixedly provided. At the bottom of the first conveyor frame 1, two rotating brackets 33 are fixedly provided. On the opposite sides of the two rotating brackets 33, a cleaning brush roller 34 is rotatably connected. On the surface of the cleaning brush roller 34, two second belt pulleys 35 are fixedly provided. The two first belt pulleys 32 and the second belt pulleys 35 are divided into front and rear groups, and a first belt 36 is sleeved on the surface of each group. On the back of the first conveyor frame 1, a drive motor 37 is provided for driving the drive shaft 31 to rotate;

[0053] Please combine Figure 3 : Start the drive motor 37. The drive motor 37 rotates to drive the drive shaft 31 and the two first belt pulleys 32 to rotate. The two first belt pulleys 32 drive the two second belt pulleys 35 to rotate through the first belt 36. The two second belt 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, start the drive motor 37 to make the drive motor 37 rotate forward and backward. The drive motor 37 drives the cleaning brush roller 34 to rotate forward and backward through the drive shaft 31, the first belt pulley 32, the first belt 36 and the second belt pulley 35. When the side of the rotten or spoiled vegetable leaf adheres strongly to the first conveyor belt 22, the cleaning brush roller 34 can clean the rotten or spoiled vegetable leaf from the other direction, thereby improving the cleaning effect of the cleaning brush roller 34;

[0055] The detection mechanism 4 includes two first toothed plates 41 slidably connected to the inside of the first conveyor frame 1. On the surface of the drive shaft 31 and outside the first conveyor frame 1, two drive gears 42 are fixedly provided. The two drive gears 42 are respectively engaged with the two first toothed plates 41. On the surface of the front first toothed plate 41, a sliding frame 43 is fixedly provided. Inside the sliding frame 43, a vertical plate 44 is slidably connected. At the bottom of the inner wall of the sliding frame 43, a return spring 45 is fixedly provided. The top of the return spring 45 is fixedly connected to the bottom of the vertical plate 44. On the back of the top of the vertical plate 44, an industrial camera 46 is fixedly provided. Inside the top of the vertical plate 44, a rotating wheel 47 is rotatably connected. On the top of the first conveyor frame 1, a support frame 48 is fixedly provided. On the front side of the support frame 48, a trapezoidal plate 49 is fixedly provided;

[0056] Please combine Figure 5 and Figure 6During the rotation of the drive shaft 31, two drive gears 42 will be driven to rotate clockwise at the same time. The two drive gears 42 rotate clockwise to drive the two first toothed plates 41 to move to the left. During the movement of the front first toothed 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, through the cooperation of the rotating wheel 47 and the trapezoidal plate 49, the vertical plate 44 will drive the industrial camera 46 to move downward, and the return spring 45 will contract. By moving the industrial camera 46 to the lower left, the vegetables can be tracked and detected while changing the detection orientation, thereby improving the detection effect of the industrial camera 46 on the vegetables;

[0057] Further, when the industrial camera 46 moves to the left and completes the tracking and detection of the vegetables, the drive shaft 31 rotates in reverse to drive the two drive gears 42 to rotate counterclockwise. The two drive gears 42 rotate counterclockwise to drive the two first toothed plates 41 to move to the right. When the front first toothed plate 41 moves to the right, the sliding frame 43, the vertical plate 44, the rotating wheel 47 and the industrial camera 46 will be driven to move to the right at the same time. Through the elastic force of the return spring 45, the rotating wheel 47 will closely adhere to the bottom of the trapezoidal plate 49 during the movement, so that the industrial camera 46 can be reset to the upper right for detecting the next vegetable;

[0058] The scraping mechanism 5 includes connecting rods 51 fixed to the right sides of the bottoms of the two first toothed plates 41. Arc-shaped scraping plates 52 are arranged on the surfaces of the two connecting rods 51. Locking nuts 53 are threadedly connected to the surfaces of the two connecting rods 51 and located at the top and bottom of the arc-shaped scraping plates 52;

[0059] Please combine Figure 7 and Figure 8 : During the movement of the two first toothed plates 41 to the left, the two connecting rods 51 will be driven to move to the left at the same time. Through the movement of the two connecting rods 51, the arc-shaped scraping plate 52 will be driven to move to the left. When the vertical plate 44 drives the industrial camera 46 to reach the leftmost position, the arc-shaped scraping plate 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-shaped scraping plate 52 will be cleaned at the same time, avoiding the accumulation of too many vegetable leaves on the surface of the arc-shaped scraping plate 52 and affecting the cleaning effect of the first conveyor belt 22;

[0060] Further, when the two first toothed plates 41 move to the right, the arc-shaped scraping plate 52 will be driven to move to the right at the same time through the two connecting rods 51, so as to reset the position of the arc-shaped scraping plate 52;

[0061] Preferably, the arc-shaped scraper 52 can scrape the vegetable leaves adhered 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-shaped scraper 52 and the bottom of the first conveyor belt 22 can be adjusted, thereby improving the flexibility of the arc-shaped scraper 52 during use.

[0062] A groove for the cooperation of the two first toothed plates 41 is provided inside the first conveying frame 1 to provide left and right sliding for the two first toothed plates 41. The rotating wheel 47 is used in cooperation with the trapezoidal plate 49. When the vertical plate 44 moves to the left, under the cooperation of the rotating wheel 47 and the trapezoidal plate 49, the vertical plate 44 slides downward inside the sliding frame 43.

[0063] The inner arc of the arc-shaped scraper 52 is the same as the outer surface arc of the cleaning brush roller 34. A through hole for the cooperation of the connecting rod 51 is provided inside the arc-shaped scraper 52.

[0064] In this embodiment, different from the existing pickled vegetable pretreatment conveying device, in this case, the forward and reverse rotation of the driving motor 37 drives the driving shaft 31 and the cleaning brush roller 34 to rotate forward and backward, so that the vegetable leaves adhered to the surface of the first conveyor belt 22 can be cleaned from two different directions, improving the cleaning effect on rotten or deteriorated vegetable leaves. When the driving shaft 31 rotates clockwise, it will drive the two first toothed plates 41 to move to the left through the driving gear 42. During the movement of the front first toothed plate 41, it will drive the industrial camera 46 to move left and downward, so as to change the detection angle during the process of tracking and detecting vegetables, thereby improving the detection effect of the industrial camera 46 on vegetables. When the two first toothed plates 41 move to the left, they will drive the arc-shaped scraper 52 to move to the left through the two connecting rods 51. When the vertical plate 44 drives the industrial camera 46 to reach the leftmost position, the arc-shaped scraper 52 will contact the cleaning brush roller 34, so that while not affecting the cleaning effect of the arc-shaped scraper 52 on the first conveyor belt 22, the cleaning brush roller 34 is used to clean the vegetable leaves remaining on the surface of the arc-shaped scraper 52, eliminating the need for manual cleaning during downtime, and thus improving the processing efficiency of pickled vegetables and the cleaning effect on rotten or deteriorated vegetable leaves.

[0065] Second Embodiment:

[0066] Please refer to Figures 9 to 11, a material blocking mechanism 6 is slidably connected to the inner side of the first conveying rack 1. The material blocking mechanism 6 includes a second toothed plate 61 slidably connected to the inner side of the first conveying rack 1. The second toothed plate 61 meshes with the front driving gear 42. A first rotating seat 62 is fixedly provided on the right side of the top of the second toothed plate 61. A sliding seat 63 is fixedly provided on the top of the first conveying rack 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. A second rotating seat 66 is fixedly provided on the front side of the bottom of the slide rail 64. 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 Figure 9 and Figure 10 : When the drive shaft 31 drives the two driving gears 42 to rotate clockwise, the front driving gear 42 will drive the second toothed plate 61 to move to the right. The second toothed plate 61 moves to the right and then drives the slide rail 64 to slide backward inside the sliding seat 63 through the connecting rod 67. The movement of the slide rail 64 drives the material blocking plate 65 to block the vegetables, so that the vegetables stay at the same position briefly, facilitating the staff to visually distinguish the quality of the vegetables, reducing the activity of the staff's neck, and thus reducing the fatigue of the staff. Moreover, 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;

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

[0069] A flexible material pushing mechanism 7 is fixedly provided on the right side of the top of the first conveying rack 1. The flexible material pushing mechanism 7 includes a mounting bracket 71 fixedly provided on the right side of the top of the first conveying rack 1. A hydraulic rod 72 is fixedly provided on the top of the mounting bracket 71. The output end of the hydraulic rod 72 is fixedly provided with a connecting plate 73. Two guide rods 74 are fixedly provided on the surface of the connecting plate 73. A material pushing plate 75 is slidably connected to the surfaces of the two guide rods 74. Buffer springs 76 are sleeved on the surfaces of the two guide rods 74 and located on the front side of the material pushing plate 75;

[0070] Please combine Figure 11: After the vegetables are detected by the industrial camera 46, if the surface of the vegetables shows rot or the surface of the vegetable leaves is severely damaged, the background processor will issue an instruction to the hydraulic rod 72, and the hydraulic rod 72 will then extend and drive the connecting plate 73 and the pushing plate 75 to move backward. By the backward movement of the pushing plate 75, the vegetables that do not meet the detection standard are pushed away from the first conveyor belt 22. Then, the rotten or damaged vegetable leaves on the surface of the vegetables are removed manually. After the removal, the qualified vegetables are placed back on the top of the first conveyor belt 22, and the first conveyor belt 22 is used to transport the vegetables to the next working position.

[0071] In this embodiment, by the clockwise rotation of the drive shaft 31 and the drive gear 42, the second toothed plate 61 moves to the right. Under the action of the connecting rod 67, the slide rail 64 and the baffle 65 slide backward inside the sliding seat 63, so that the vegetables stay at the same position briefly, which is convenient for the staff to distinguish the quality of the vegetables by the naked eye, reduces the activity of the staff's neck, and then reduces the fatigue of the staff. And the brief stay of the vegetables enables the industrial camera 46 and the background processor to have sufficient time to distinguish the quality of the vegetables. The vegetables that do not meet the detection standard will be driven by the hydraulic rod 72, and the pushing plate 75 is used to push them away from the first conveyor belt 22. After the rotten or damaged vegetable leaves on the surface are removed manually, the first conveyor belt 22 is used to transport the vegetables to the next working position.

[0072] Third Embodiment:

[0073] Please refer to Figure 1 、 Figure 2 、 Figure 12 and Figure 13 The bottom of the first conveyor frame 1 is provided with a second conveying mechanism 8.

Two second conveyor rollers 82 are rotatably connected inside the second conveyor frame 81. A second conveyor belt 83 is sleeved on the surfaces of the two second conveyor rollers 82. Protective seats 84 are fixedly arranged on both sides of the top of the second conveyor frame 81;

[0074] Please combine Figure 12 : The rotation of the two second conveyor rollers 82 can drive the second conveyor belt 83 to rotate. Through the arrangement of the protective seats 84, it can be avoided that the rotten or deteriorated vegetable leaves are separated from the second conveyor 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 the rotten or deteriorated vegetable leaves fall on the first conveyor belt 22, they can accurately fall on the top of the second conveyor belt 83, which is convenient for the subsequent collection work of the rotten or deteriorated vegetable leaves.

[0076] At the front end of the first conveying roller 21 on the left side, a driving mechanism 9 is fixedly installed. The driving mechanism 9 includes a third pulley 91 fixedly installed at the front end of the first conveying roller 21 on the left side.

The back surface of the bottom transmission gear 93 is fixedly connected to the front end of the second conveying roller 82 on the left side. The back surface of the top transmission gear 93 is fixedly provided with a fourth pulley 94. A second belt 95 is sleeved on the surfaces of the third pulley 91 and the fourth pulley 94;

[0077] Please combine Figure 1 and Figure 13 : When the first conveying roller 21 on the left side rotates counterclockwise, it will drive the third pulley 91 to rotate counterclockwise at the same time. The rotation of the third pulley 91 drives the fourth pulley 94 to rotate counterclockwise through the second belt 95. When the fourth pulley 94 rotates, it will drive the top transmission gear 93 to rotate counterclockwise at the same time. The counterclockwise rotation of the top transmission gear 93 drives the bottom transmission gear 93 to rotate clockwise. The clockwise rotation of the bottom transmission gear 93 drives the second conveying roller 82 on the left side to rotate clockwise, so that the second conveyor belt 83 conveys the rotten or spoiled vegetable leaves to the right.

[0078] On the left side of the back surface of the first conveying frame 1, a workbench 10 is fixedly installed. A guide frame 11 is fixedly installed at the bottom of the workbench 10. A collection box 12 is arranged on the right side of the bottom of the second conveyor belt 83. Six support legs 13 are fixedly installed on the surfaces of the first conveying frame 1 and the second conveying frame 81. A laser distance sensor 14 is fixedly installed on the front surface of the rear support leg 13. A punching protection plate 15 is fixedly installed on the front surface of the front support leg 13;

[0079] Preferably, the workbench 10 is used to store the vegetables that fail the inspection. After the staff remove the rotten or spoiled vegetable leaves on the surface and throw them on the guide frame 11, the rotten or spoiled vegetable leaves will fall on the top of the second conveyor belt 83 after passing through the guide frame 11. The rotten or spoiled vegetable leaves conveyed by the second conveyor belt 83 will finally fall into the collection box 12. Through the setting of the laser distance sensor 14, it can sense whether there are vegetables being transported to the left on the top of the first conveyor belt 22, so as to facilitate controlling the driving motor 37 to work.

[0080] In this embodiment, when the first conveyor belt 22 conveys vegetables to the left, the third pulley 91 is driven to rotate counterclockwise by the counterclockwise rotation of the first conveyor roller 21. The third pulley 91 drives the fourth pulley 94 to rotate counterclockwise through the second belt 95. When the fourth pulley 94 rotates, under the cooperation of the two transmission gears 93, the second conveyor roller 82 on the left rotates clockwise, and then the rotten or deteriorated vegetable leaves are conveyed to the right by the second conveyor belt 83 and are conveyed into the collection box 12.

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

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

[0083] Step S2, start the driving motor 37 to make the driving motor 37 rotate forward and backward. The driving motor 37 thus drives the cleaning brush roller 34 to rotate forward and backward through the driving shaft 31, the first pulley 32, the first belt 36 and the second pulley 35, and uses the forward and backward rotation of the cleaning brush roller 34 to clean the bottom of the first conveyor belt 22.

[0084] When the driving shaft 31 rotates clockwise, it drives the two driving gears 42 to rotate clockwise. The two driving gears 42 rotating clockwise drive the two first toothed plates 41 to move to the left. During the process of the front first toothed plate 41 moving to the left, it will simultaneously drive the sliding frame 43, the vertical plate 44, the rotating wheel 47 and the industrial camera 46 to move to the left. During the process of the vertical plate 44 moving to the left, through the cooperation of the rotating wheel 47 and the trapezoidal plate 49, the vertical plate 44 drives the industrial camera 46 to move downward, and the return spring 45 is contracted. By the industrial camera 46 moving to the lower left, while tracking and detecting the vegetables, the detection orientation is changed, so as to improve the detection effect of the industrial camera 46 on the vegetables.

[0085] During the process of the two first toothed plates 41 moving to the left, they will simultaneously drive the two connecting rods 51 to move to the left. The movement of the two connecting rods 51 drives the arc-shaped scraper 52 to move to the left. When the vertical plate 44 drives the industrial camera 46 to reach the leftmost position, the arc-shaped scraper 52 will contact the cleaning brush roller 34, and when the cleaning brush roller 34 rotates, it will simultaneously clean the bottom of the first conveyor belt 22 and the surface of the arc-shaped scraper 52.

[0086] Step S3, when the drive shaft 31 drives the two drive gears 42 to rotate clockwise, the front drive gear 42 will drive the second toothed plate 61 to move to the right. The second toothed plate 61 moves to the right and drives the slide rail 64 to slide backward inside the sliding seat 63 through the connecting rod 67. The movement of the slide rail 64 drives the baffle plate 65 to block the vegetables, so that the vegetables stay at the same position briefly, facilitating the staff to visually distinguish the quality of the vegetables, reducing the movement of the staff's neck, and thus reducing the fatigue of the staff;

[0087] When the drive shaft 31 drives the two drive gears 42 to rotate counterclockwise, the front drive gear 42 will drive the second toothed plate 61 to move to the left. The second toothed plate 61 moves to the left and drives the slide rail 64 to slide forward inside the sliding seat 63 through the connecting rod 67, thereby resetting the positions of the slide rail 64 and the baffle plate 65, and enabling the vegetables to continue moving to the left under the conveyance of the first conveyor belt 22;

[0088] After the vegetables are detected by the industrial camera 46, if the surface of the vegetables shows rot or the surface of the vegetable leaves is severely damaged, the background processor will issue an instruction to the hydraulic rod 72. The hydraulic rod 72 will then extend and drive the connecting plate 73 and the pushing plate 75 to move backward. The backward movement of the pushing plate 75 pushes the vegetables that do not meet the detection standard away from the first conveyor belt 22. Then, the staff manually removes the rotten or damaged vegetable leaves on the surface of the vegetables. After the removal, the qualified vegetables are placed back on the top of the first conveyor belt 22, and the first conveyor belt 22 is used to transport the vegetables to the next working position;

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

[0090] After the staff removes the rotten or deteriorated vegetable leaves on the surface of the vegetables on the workbench 10 and throws them on the guide frame 11, the rotten or deteriorated vegetable leaves will fall on the top of the second conveyor belt 83 after passing through the guide frame 11. The vegetable leaves cleaned by the cleaning brush roller 34 and the arc-shaped scraper 52 will also fall on the top of the second conveyor belt 83 under the influence of gravity. Through the conveyance of the second conveyor belt 83, the rotten or deteriorated vegetable leaves are conveyed into the collection box 12.

[0091] The above are only the preferred embodiments of the present invention, and do not limit the patent scope of the present invention. Any equivalent structural transformation made under the concept of the present invention by using the content of the specification and drawings of the present invention, or directly / indirectly applied in other related technical fields, is included in the patent protection scope of the present invention.
