Description

Technical Field

[0001] This utility model relates to the field of navel orange cultivation, specifically to a processing table used for screening navel oranges. Background Technology

[0002] Navel oranges are beloved by consumers for their unique flavor and rich nutrition. Harvesting after ripening is crucial in the cultivation process. To ensure the quality and taste of the fruit, it's necessary to screen the oranges, classifying them by size and checking for signs of pests or diseases, ensuring they are free of insect infestation or blemishes. Processing tables are used during this screening process to speed up the process.

[0003] Currently, most processing stations simply involve pouring navel oranges onto the surface and manually sorting them by size. At the same time, the oranges' peels are inspected; those with smooth peels, no obvious spots, scars, or damage are placed in the premium category, while those that don't meet the requirements are removed and placed separately. This manual sorting is not only time-consuming and labor-intensive, but also inefficient. Utility Model Content

[0004] To address the problems of existing processing tables, which mostly involve simply pouring navel oranges onto the table and manually sorting them by size while inspecting the peel (placing oranges with smooth peels, no obvious spots, scars, or damage in the premium category, and separating the substandard ones), this invention provides a processing table for sorting navel oranges.

[0005] A processing table for screening navel oranges includes a worktable with a conveying unit, a cleaning unit, and a screening unit arranged sequentially on it. The conveying unit and the cleaning unit each include several conveying rollers and cleaning rollers rotating on the worktable.

The control panel is electrically connected to several electric telescopic rods, several image acquisition devices, and three servo motors.

[0011] Compared with the prior art, the beneficial effects of this utility model are as follows: First, the navel oranges are cleaned of surface dust using a cleaning sponge on a cleaning roller. Then, they fall sequentially into a size-sorting rotating drum according to their size, where they are sorted. The sorted oranges are then transported through a conveyor channel where an image acquisition device captures images of the orange surface. Based on the presence of insects, blemishes, scars, or damage, superior and inferior oranges are automatically distinguished. Inferior oranges are pushed into the inferior orange channel for collection, while superior oranges are collected through the superior orange channel. The entire process is automated under the control system within the control panel, improving the sorting efficiency based on orange size and surface condition. Attached Figure Description

The following will refer to the accompanying drawings. Figures 1-5 The present invention will be described in detail with reference to the embodiments.

[0023] A processing table for screening navel oranges includes a workbench 1, on which a conveying unit, a cleaning unit, and a screening unit are sequentially arranged. The conveying unit and the cleaning unit each include several conveying rollers 2 and cleaning rollers 3 rotating on the workbench. The screening unit includes several large and small screening drums 4. The navel oranges are poured onto the conveying rollers 2, and the rotation of the conveying rollers 2 drives the navel oranges towards the cleaning rollers 3. Since an inverted U-shaped limiting rod 25 is fixedly installed on the workbench 1 between the conveying rollers 2 and the cleaning rollers 3, the inverted U-shaped limiting rod 25 can limit the navel oranges and prevent them from being transported to the cleaning rollers 3 in a pile, so that the navel oranges can be transported to the cleaning rollers 3 row by row. A cleaning sponge 17 is fixedly installed on the outer wall of the central shaft of the cleaning roller 3, which can clean the outer wall of the navel oranges. The cleaning sponge 17 cleans the surface of the navel oranges. When the navel oranges rotate and come into contact with the cleaning sponge 17, the cleaning sponge 17 will rub off the dust on the surface of the navel oranges, making it easier for the subsequent image acquisition device 6 to capture clearer images.

[0024] Three sets of vertical plates 12 are fixedly installed on the outer wall of the workbench 1. Each of the three sets of vertical plates 12 has a servo motor 13 installed on its outer wall via a mounting bracket. Each of the three sets of vertical plates 12 has a rotating shaft 14 rotatably installed inside. Several external bevel gears 15 are fixedly installed on the outer wall of the rotating shaft 14. The central shafts of the conveying roller 2, the cleaning roller 3, and the large and small screening rollers 4 are all rotatably installed on the workbench 1, and an internal bevel gear 16 is fixedly installed at one end of each central shaft.

[0025] Start the servo motor 13 to drive the rotating shaft 14 to rotate, which in turn drives several outer bevel gears 15 to rotate. Since the outer bevel gears 15 and the inner bevel gears 16 are meshed and connected, they can further drive several inner bevel gears 16 to rotate, that is, drive the conveying roller 2, the cleaning roller 3 and the large and small screening rollers 4 to rotate, so as to achieve the purpose of conveying, cleaning and screening.

[0026] A bevel gear 16 is fixedly connected to the central shaft at one end of the large and small screening drum 4, and an opening is provided at the other end. The outer wall of the opening is rotatably mounted on the worktable 1 via a rotating bearing. The large and small screening drum 4 has a receiving cavity inside, through which several screening holes 18 are provided. The screening holes 18 in each large and small screening drum 4 are of different sizes and arranged in order of size, with the smallest screening hole 18 being closer to the cleaning roller 3. The navel oranges conveyed in order of size fall into the receiving cavity through the screening holes 18, and then flow into the funnel-shaped guide 19 from the opening.

[0027] A funnel-shaped guide 19 is fixedly installed at the opening of the large and small screening drum 4. One end of the funnel-shaped guide 19 is connected to the feed end of the premium channel 10. The funnel-shaped guide 19 can guide the navel oranges screened by size to converge into the conveying channel 5. Each large and small screening drum 4 is equipped with a corresponding conveying channel 5. The conveying channel 5 includes a lower premium channel 10 and an upper inferior channel 11. Each navel orange moves along the premium channel 10. After the image acquisition device 6 distinguishes the navel oranges with skin defects, the pusher plate 8 pushes the defective navel oranges into the inferior channel 11.

[0028] Inside the premium channel 10, a push plate 8 and a baffle 9 are movably installed via an electric telescopic rod 7. The size of the conveying channel 5 is larger than the size of the corresponding screening hole 18. Image acquisition devices 6 are installed around the push plate 8. The overall structure of the conveying channel 5 is inclined, with the upper inclined end close to the opening of the large and small screening drums 4. There are several image acquisition devices 6, which are fixedly installed on the side wall and top wall between the funnel-shaped guide 19 and the baffle 9 in the premium channel 10. They can collect images of the navel oranges from all sides. The push plate 8 can push the inferior navel oranges from the premium channel 10 to the inferior channel 11.

[0029] The navel orange slides along the premium channel 10. During the sliding process, several image acquisition devices 6 can take pictures of the surface of the navel orange. Since the support plate 20 is also fixedly equipped with a control panel 24, and the control panel 24 is electrically connected to several electric telescopic rods 7, several image acquisition devices 6, and three servo motors 13.

[0030] When the image captures a defect on the surface of the navel orange, the control panel 24 receives the defect image and the internal control system can control the electric telescopic rod 7 to move upward, which in turn moves the baffle 9 upward to block the defective navel orange and prevent it from moving further. At the same time, another electric telescopic rod 7 moves the push plate 8 upward, which pushes the defective navel orange through the through hole 21 into the defective product channel 11, so that the defective navel orange can be collected separately along the defective product channel 11.

[0031] A support column is fixedly installed on the bottom wall of the conveying channel 5. Two support plates 20 are fixedly installed on the support column. Electric telescopic rods 7 are fixedly installed on the two support plates 20 respectively. The bottom and top walls of the premium channel 10 and the bottom wall of the inferior channel 11 are all provided with through holes 21. The through holes 21 can accommodate the passage of the push plate 8 and the baffle 9 respectively. The side wall of the premium channel 10 is also fixedly provided with a limit groove 22. The push plate 8 and the baffle 9 are slidably installed in the limit groove 22 respectively.

[0032] When the push plate 8 moves to the bottom of the limiting groove 22, the top wall of the push plate 8 is flush with the bottom wall of the premium channel 10, which facilitates the conveying of navel oranges from the premium channel 10 to the receiving box 23. When the push plate 8 moves to the top of the limiting groove 22, the top of the push plate 8 is flush with the bottom wall of the inferior channel 11, which can push the defective navel oranges onto the inferior channel 11.

[0033] Similarly, when the baffle 9 moves to the bottom of the limiting groove 22, the top wall of the baffle 9 is flush with the bottom wall of the premium channel 10, which facilitates the conveying of navel oranges from the premium channel 10 to the receiving box 23. When the baffle 9 moves to the top of the limiting groove 22, the baffle 9 is in the middle of the premium channel 10, which can prevent defective navel oranges from moving downwards.

[0034] Both the superior product channel 10 and the inferior product channel 11 have movable receiving boxes 23 below their discharge ends, which can collect qualified navel oranges and defective navel oranges respectively.

[0035] The above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model. Various modifications and variations can be made to this utility model by those skilled in the art. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
