Description

Technical Field

[0001] The utility model relates to the technical field of sorting equipment, in particular to a sorting device for baby cabbage. Background Art

[0002] Baby cabbage is a pocket-sized cabbage belonging to the Brassica rapa subspecies of the Cruciferae family. The general growth period is 45 to 55 days. When the whole plant is 30 to 35 cm tall and the ball is tightly wrapped, it can be harvested. When harvesting, the whole plant should be pulled out, the excess outer leaves should be removed, the base should be flattened, and it can be put on the market after sorting and packaging with plastic wrap. Baby cabbage sorting is an important part. By sorting, baby cabbages with consistent shapes are obtained, which is convenient for packaging and can improve the aesthetics at the same time, and is convenient for sale. In the prior art, the sample is first determined during sorting, and then sorted by manual comparison with the sample, which is time-consuming, labor-intensive and subjective.

DETAILED DESCRIPTION

[0015] In order to achieve the above-mentioned purpose and effect, the technical means and structure adopted by the utility model are described in detail with reference to the accompanying drawings for the preferred embodiments of the utility model and their features and functions.

[0016] like Figure 1-2As shown, the utility model provides a sorting device for baby cabbage, comprising a first conveyor belt 1, a plurality of measuring and pushing mechanisms are arranged on the frame of the first conveyor belt 1, and a waste chute 2 is arranged at the end of the frame of the first conveyor belt 1; the measuring and pushing mechanism comprises a measuring unit and a pushing unit arranged behind the measuring unit; the measuring unit comprises two sliding sleeves 7 symmetrically arranged on both sides of the frame of the first conveyor belt, and sliding rods 8 are slidably arranged in the two sliding sleeves 7, and the tops of the two sliding rods 8 are connected to a central shaft 9 in common, and a first roller 10 is rotatably sleeved on the central shaft 9, and a displacement sensor 11 is arranged on one side of the frame of the first conveyor belt 1, and the displacement sensor 11 is located below the central axis 9 and the working end of the displacement sensor 11 is connected to the central axis 9; the pushing mechanism includes a cylinder 5 arranged on one side of the frame of the first conveyor belt 1, and a U-shaped bracket 4 is arranged at the output end of the cylinder 5. The second roller 6 is rotatably arranged at the open end of the U-shaped bracket 4. In a normal state, the cylinder 5 is in an extended state, and the second roller 6 is located on one side of the frame; an opening 12 is arranged on the side of the frame of the first conveyor belt 1 opposite to the second roller 6, and a discharging chute 13 is arranged on the opening 12. The width of the first conveyor belt 1 is greater than the maximum diameter of the baby cabbage and less than the minimum length of the baby cabbage, so that the baby cabbage can only pass vertically but not horizontally.

[0017] When in use, the baby cabbage is placed vertically on the first conveyor belt 1, and the first conveyor belt 1 drives the baby cabbage to move forward. When passing through the first measuring and pushing mechanism, the baby cabbage enters from under the first roller 10. Under the continuous squeezing of the baby cabbage, the first roller 10 is lifted up, and the first roller 10 synchronously drives the central axis 9 to move upward, and then pulls out the pull rod of the displacement sensor 11 to measure the displacement value. After the baby cabbage passes, the first roller 10 falls back to its position due to its own gravity, and the measuring unit completes the measurement and takes the maximum value. When the maximum value meets the set range, the control cylinder 5 retracts and extends out again to reset. When retracting, it drives the second roller 6 to move toward the opening 12, and pushes the baby cabbage into the discharging chute 13. The next process is carried out below the discharging chute 13; when the maximum value does not meet the set range, the cylinder 5 does not move, and the baby cabbage will continue to be conveyed by the first conveyor belt 1. Similarly, when passing through other measuring and pushing mechanisms, such actions are performed to complete the sorting. Finally, unqualified baby cabbage is discharged from the waste chute 2. The utility model can sort baby cabbages according to their diameters, and can obtain baby cabbages with uniform shapes. By arranging a plurality of measuring and pushing mechanisms, a plurality of diameter range sorting standards are formed, which is not affected by human subjectivity, and adopts a conveyor belt for transportation, thus saving time and labor.

[0018] In another embodiment, if Figure 3As shown, the front end of the first conveyor belt 1 is provided with a second conveyor belt 14, the width of the second conveyor belt 14 is greater than the width of the first conveyor belt 1, the frame side of the first conveyor belt 1 is aligned with the frame side of the second conveyor belt 14, and connected by a connecting plate 18; the front end of the frame side of the first conveyor belt 1 away from the connecting plate 18 is provided with a first support rod 15, the middle part of the frame side of the second conveyor belt 14 away from the connecting plate 18 is provided with a second support rod 17, and a third roller 16 is rotatably provided between the first support rod 15 and the second support rod 17. By providing the second conveyor belt 14, the feeding range is expanded, and manual sorting is not required. The third roller 16 will automatically arrange the baby cabbages in a vertical form to ensure that each baby cabbage entering the first conveyor belt 1 is arranged vertically.

[0019] In another embodiment, a plurality of rotatable stop posts 3 are provided on both sides of the frames of the first conveyor belt 1 and the second conveyor belt 14 for correcting the position of the baby cabbage and preventing the baby cabbage from escaping from the first conveyor belt 1 and the second conveyor belt 14 .

[0020] In another embodiment, the first roller 10, the second roller 6, the third roller 16 and the blocking column 3 are all made of materials such as rubber to prevent the baby cabbage from being damaged.

[0021] The above description is only the preferred embodiment of the utility model, not all embodiments. Anyone should be aware that structural changes made under the inspiration of the utility model, and all technical solutions that are the same or similar to the utility model, belong to the protection scope of the utility model.
