Description

Technical Field

[0001] This utility model relates to the field of sorting equipment technology, specifically to a fruit size sorting device. Background Technology

[0002] Guangxi is a major fruit-producing province in my country. Every year after the fresh fruit is harvested, it undergoes simple processing and is then sieved according to its actual size to separate it into different grades, thereby maximizing the benefits of the product.

[0003] Currently, fruit sorting generally relies on sorting cylinders and sieve-type sorting methods. Sorting cylinders typically involve arranging multiple cylinders of varying sizes on their surfaces, forming a conveyor channel. The fruit moving through this channel is guided by each cylinder, allowing it to adaptively fall into the corresponding size cylinder based on its individual size, thus achieving the sorting purpose. For example, the technical solution disclosed in patent CN202322982938.5 – An Automatic Fruit Size Sorting Device. While this method is highly efficient, the sidewalls of the sorting holes on the rotating cylinders can scratch the fruit's skin, making it only suitable for sorting fruits with thicker peels.

[0004] Screen-type sorting, similar to a sieve, uses different grid spacings to separate fruits of different sizes. Its roll height is controllable, making it suitable for sorting soft fruits, as illustrated in patent CN202222456515.5 – A Fruit Sorting Machine for Size Sorting. Because the equipment used in the sorting cylinder is more complex than that used in screen-type sorting, its manufacturing cost is higher, making it more suitable for large distributors. Currently, screen-type sorting only separates fruits of relatively fixed sizes, which cannot be adjusted, making it inconvenient to use and less adaptable. Utility Model Content

[0027] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only for explaining this utility model and are not intended to limit this utility model.

[0028] Reference Figures 1 to 4 The fruit size sorting device shown includes a frame 10 and several sorting mechanisms 20. All sorting mechanisms 20 are arranged side by side. Each sorting mechanism 20 includes a pair of rollers 21. Both ends of the pair of rollers 21 are movably connected by an adjusting component 22. The adjusting component 22 can adjust the distance between the two rollers 21. Both adjusting components 22 are mounted on the frame 10. The two rollers 21 are inclined on the frame 10, and the two rollers 21 are arranged in a V-shape with the larger opening end located at the bottom. A shock-absorbing baffle 11 is provided at the lower end of the frame 10 of the two rollers 21. Several collection boxes 30 are provided below all sorting mechanisms 20 on the frame 10. All collection boxes 30 are arranged side by side along the length of the rollers 21.

[0029] In this application, the sorting mechanism 20 is preferably provided in three groups, and each group of sorting mechanisms 20 is separated by a partition. The adjusting component 22 can be composed of two L-shaped block structures connected by threads, which can adjust the distance between the rollers 21 at both ends of the adjusting component 22. The shock-absorbing baffle 11 is mainly used to limit the rolling of excessively large fruits and prevent them from rolling out of the ends of the two rollers 21. The back of the shock-absorbing baffle 11 is connected to the frame 10 by a spring to prevent excessive impact during the rolling of the fruit and damage to the fruit. Of course, in some embodiments, a sponge is provided on the side of the shock-absorbing baffle 11 that collides with the fruit to prevent frontal impact with the fruit.

[0030] This fruit size sorting device features a multi-group sorting mechanism 20. This structure facilitates large-scale sorting and improves sorting efficiency. Each sorting mechanism 20 consists of two V-shaped rollers 21 forming the basic sorting structure. Different sizes of fruit are sorted by utilizing the varying spacing between the two rollers 21 at different positions, making the process simple and convenient. The two ends of the rollers 21 are fixed by the adjusting component 22, which not only facilitates installation and fixation but also allows adjustment of the spacing between the two rollers 21 to accommodate different sorting requirements and the sorting needs of different types of fruit, thus improving ease of use and adaptability.

[0031] See Figures 1 to 2 To facilitate movement, the bottom of the frame 10 is provided with several casters 16 with brakes.

[0032] In some embodiments, to facilitate the collection of fallen fruit, a guide plate 17 is inclinedly arranged below the sorting mechanism 20 on the frame 10. The guide plate 17 is provided with a plurality of partitions 12, and all the partitions 12 divide the guide plate 17 into a plurality of guide channels 13. Each guide channel 13 is lined with a sponge layer 14. A support plate 15 is provided on one side of the bottom of the guide plate 17 on the frame 10. All the collection boxes 30 are arranged on the support plate 15 and receive the fruit discharged from the corresponding guide channel 13.

[0033] See Figures 3 to 4 In one embodiment of this application, to facilitate adjustment without interfering with fruit sorting, each adjustment component 22 includes a mounting base 23, a double-ended screw 24 rotatably mounted on the mounting base 23, and sliding blocks 25 screwed onto both ends of the double-ended screw 24. The mounting base 23 is mounted on the frame 10, and both sliding blocks 25 are slidably mounted on the mounting base 23. The same end of each of the two rollers 21 is movably mounted on the two sliding blocks 25, and the threads on both ends of the double-ended screw 24 rotate in opposite directions. When it is necessary to adjust the distance between the two sliding blocks 25, simply rotate the double-ended screw 24. An operating structure is provided in the middle of the double-ended screw 24. The operating structure is either a conventional six-headed nut or two parallel cuts on opposite sides of the sidewall of the double-ended screw 24, facilitating rotation with a wrench. Alternatively, an operating arm can be welded directly to the middle of the double-ended screw 24. The operating arm and the double-ended screw 24 are arranged in a T-shape, so that the user only needs to push the operating arm to make the double-ended screw 24 rotate.

[0034] In the above-mentioned improved scheme, in order to facilitate the sliding of the sliding block 25, slide rails 26 are provided on both ends of the mounting base 23, and the two sliding blocks 25 are respectively slidably mounted on the two slide rails 26.

[0035] In the above-mentioned improved solution, in order to facilitate installation, the mounting base 23 is provided with a plurality of mounting holes 29, and the mounting base 23 is installed on the frame 10 by means of screws passing through the mounting holes 29.

[0036] In one embodiment of this application, to accommodate the installation of the roller 21 and to prevent partial contact between the roller 25 and the center, each roller 25 is provided with a slot 27. One end of the roller 21 is movably engaged in the slot 27, and the side of the top of the roller 21 can extend out of the opening of the slot 27. In actual use, the position of the roller 21 in the slot 27 varies depending on the distance between the two rollers 21. Therefore, the roller 21 can deform to a certain extent. This structural design allows the roller 21 to adapt to the changes in fit caused by variations in the distance between the two rollers 25. In actual use, the roller 25 is generally connected to the end of the roller 21. In this case, the end of the roller 21 can be pre-bent to accommodate different distances between the two rollers 25. The slot 27 is located on the upper part of the opposite side of the two rollers 25, and the opening of the slot 27 is actually inclined upwards.

[0037] Of course, in one embodiment of this application, the sliding block 25 is a split design, with a sliding part at the bottom and a rotatable mounting part on the sliding part. The slot 27 is provided on the mounting part. This structure can also adapt to the two sliding blocks 25 automatically fitting the outer wall of the roller 21 due to position adjustment, ensuring normal contact and stable connection between the two.

[0038] Furthermore, in order to prevent the roller 21 from coming out of the slot 27, in one embodiment of this application, the sliding block 25 is provided with a locking screw 28 for locking the roller 21 on the periphery of the slot 27.

[0039] See Figure 5 In this application, to facilitate material feeding, a feeding hopper can be installed at the feeding end of all sorting mechanisms 20, allowing for manual, gradual feeding. Alternatively, in an improved embodiment, a feeding mechanism 40 is provided on the frame 10, with its output end connected to the upper ends of a pair of rollers 21 within all sorting mechanisms 20. The feeding mechanism 40 can be a conventional conveyor belt structure or a hopper structure.

[0040] In the improved embodiment described above, the feeding mechanism 40 includes a conveyor belt 41 and a confluence hopper 42. The conveyor belt 41 is mounted on the frame 10, and the confluence hopper 42 is mounted on the output end of the conveyor belt 41. The upper ends of a pair of rollers 21 in all the sorting mechanisms 20 are connected to the discharge end of the confluence hopper 42. The confluence hopper 42 is inclined and is used to connect the conveyor belt 41 and the feed end of the rollers 21 of each sorting mechanism 20. The outlet of the confluence hopper 42 automatically adapts to the number of different sorting mechanisms 20, and the two can be connected by a snap-fit ​​mechanism.

[0041] The above embodiments are merely preferred embodiments of this utility model and should not be construed as limiting the scope of protection of this utility model. Any non-substantial changes and substitutions made by those skilled in the art based on this utility model shall fall within the scope of protection claimed by this utility model.
