Description

Technical Field

[0001] This utility model relates to the field of melon sorting technology, and in particular to a fully automatic weight sorting machine for melons. Background Technology

[0002] Melon is an annual creeping or climbing herbaceous plant belonging to the Cucurbitaceae family and the Cucurbita genus. It originated in Africa and India and is widely cultivated throughout China. The fully automatic weight sorting machine uses advanced sensors and weighing technology to accurately measure the weight of melons and sort them accurately according to the preset weight range, thus ensuring sorting accuracy.

[0003] The melons are fed evenly into the sorting machine via a conveyor belt. They are then weighed and sorted; sensors detect the weight of the melons and transmit the data to the system, which compares the data with parameters to determine the grade. Further sorting occurs when the system sends a signal to the sorting device, which then sorts the melons according to grade. Finally, the different grades of melons are collected separately, and personnel periodically remove them for further processing, improving efficiency and quality while reducing human error.

[0004] In existing technologies, some fully automatic weight sorting machines for melons experience problems during transportation. The melons may shift and collide with other parts of the sorting machine, causing damage to the melon's skin, such as scratches, dents, or breaks, affecting its appearance and quality. Therefore, to address these shortcomings, a fully automatic weight sorting machine for melons is proposed to solve these problems. Utility Model Content

[0035] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0036] Reference Figures 1 to 3 This utility model provides an embodiment of a fully automatic weight sorting machine for melons, including a transport platform 1, which provides support for the transport of melons. A support frame 2 is fixedly connected to the bottom side of the transport platform 1, and is fixed by welding to provide stable support for the transport platform 1. A fixed frame 3 is fixedly connected to the top side of the transport platform 1, and is fixed by welding to provide stable support for the fixed frame 3. A drive assembly is fixedly connected inside the fixed frame 3, and the drive assembly provides a drive source. The drive assembly includes a motor 4, which is externally fixedly connected inside the fixed frame 3 and fixed by welding to ensure the stability of the motor 4 during operation. A gear 5 is fixedly connected to the drive end of the motor 4, and when the motor 4 starts, it can transmit power to the gear 5, driving the gear 5 to rotate.

[0037] Two sliding plates 6 are slidably connected inside the fixed frame 3, allowing the sliding plates 6 to slide stably due to the constraint of the fixed frame 3. A limiting opening 7, which is square, is provided inside the sliding plate 6. A rack 8 is fixedly connected to each adjacent side of the sliding plate 6, causing the sliding plate 6 to slide synchronously during sliding. The rack 8 is slidably connected to the inside of the limiting opening 7, allowing it to slide within another non-fixed sliding plate 6. A gear 5 is meshed with the two racks 8; when the gear 5 rotates, its meshing with the two racks 8 causes the two sliding plates 6 to move relative to or in opposite directions. A fixing block 9 is fixedly connected to the bottom of the sliding plate 6, causing it to slide synchronously. The two fixing blocks 9 are slidably connected to the front and rear ends of the fixed frame 3, allowing them to slide smoothly within the frame 3. A limiting plate 10 is fixedly connected to the bottom of the fixing block 9, causing it to slide synchronously. The fixed frame 3 has a strip opening 11 inside, which is adapted to the limiting plate 10. A sorting frame 12 is fixedly connected to the right side of the transport table 1. The sorting frame 12 is used to sort melons of different sizes.

[0038] Reference Figure 1 and Figure 2 The sorting frame 12 has multiple sorting components rotatably connected inside, each including a sorting plate 13. The external parts of the sorting plates 13 are rotatably connected inside the sorting frame 12, allowing them to rotate according to the weight of the melon. The external parts of the multiple sorting plates 13 are rotatably connected inside the sorting frame 12, ensuring stable rotation. Multiple positioning blocks 14 are fixedly connected to the front and rear sides of the sorting frame 12 via welding, providing support for the positioning blocks 14. A connecting plate 17 is fixedly connected to the bottom side of the sorting plates 13 via welding, providing support for the connecting plate 17. Convex posts 16 are fixedly connected to the opposite sides of the multiple positioning blocks 14 and the front and rear sides of the connecting plate 17 via welding, providing support for the convex posts 16. Two convex pillars 16 are fitted with torsion springs 15. When the sorting plate 13 rotates under the weight of the melon, the torsion springs 15 will deform accordingly, storing and releasing energy, so that the sorting plate 13 can return to its initial position at the appropriate time and divide into three pairs of torsion springs 15. The elastic potential energy stored in each pair of torsion springs 15 is different, and the order from left to right is large, medium and small. This allows the sorting plate 13 to withstand the weight of different melons, thereby achieving the sorting function.

[0039] Reference Figure 1 , Figure 4 and Figure 5A protective cylinder 18 is fixedly connected to the rear side of the transport platform 1, and is secured by welding to provide support for the protective cylinder 18. A second motor 19 is fixedly connected inside the protective cylinder 18, and is also secured by welding to ensure the stability of the second motor 19 during operation. A drive wheel 20 is fixedly connected to the drive end of the second motor 19, which drives the drive wheel 20 to rotate when the second motor 19 starts. A belt 21 is fitted tightly around the drive wheel 20, transmitting power through friction.

[0040] Reference Figures 6 to 8 A driven shaft 22 is rotatably connected to the right end of the transport platform 1. The transport platform 1 restricts the stable rotation of the driven shaft 22. A transmission wheel 29 is fixedly connected to the rear end of the driven shaft 22. When the transmission wheel 29 rotates, it drives the driven shaft 22 to rotate synchronously. The transmission wheel 29 is sleeved inside the belt 21, allowing the power from the driving wheel 20 to be transmitted to the transmission wheel 29, which in turn drives the driven shaft 22 to rotate. A transmission belt 23 is installed on the outside of the driven shaft 22. When the driven shaft 22 rotates, it drives the transmission belt 23 to rotate, thus transporting the melons. Transmission components are fixedly connected to both the front and rear ends of the driven shaft 22, and these transmission components are used to transmit rotational force.

[0041] Both transmission components include rotating plates 24, which are fixedly connected to the front and rear ends of the driven shaft 22, respectively, and can rotate with the driven shaft 22. Fixed rods 25 are fixedly connected to adjacent sides of the two rotating plates 24, and the rotating plates 24 drive the fixed rods 25 to rotate synchronously. An opening plate 26 is slidably connected to the outside of the transmission components. The opening plate 26 has a rectangular square opening 27 inside. The fixed rods 25 are slidably connected to the inside of the square opening 27, allowing the fixed rods 25 to push the opening plate 26 up and down. Partition plates 28 are fixedly connected to the top sides of the two opening plates 26, and the partition plates 28 are used for separating the transported melons. The partition plates 28 are slidably connected to the inside of the right end of the transport platform 1, allowing the partition plates 28 to slide stably.

[0042] Working principle: First, the melon is placed on the transmission belt 23. Then, the motor 19 is started to drive the drive wheel 20 to rotate, which in turn drives the belt 21 to rotate, which in turn drives the transmission wheel 29 to rotate, which in turn drives the driven shaft 22 to rotate. The driven shaft 22 drives the transmission belt 23 to rotate and transport the melon. At the same time, the motor 4 is started to drive the gear 5 to rotate, which in turn drives the two meshing racks 8 to slide relative to each other, which in turn drives a sliding plate 6 to slide, which in turn drives the fixed block 9 to slide, and then drives the limiting plate 10 to slide. The distance between the two limiting plates 10 can be adjusted to guide the melon to slide, prevent impact, and thus avoid reducing the quality of the melon.

[0043] At the same time, the driven shaft 22 will also drive the rotating plate 24 to rotate, thereby driving the fixed rod 25 to rotate, thereby driving the opening plate 26 to slide up and down, and then driving the partition plate 28 to slide, so that the partition plate 28 can slide intermittently, thereby achieving the effect of uniformly feeding melons, avoiding blockage and inaccurate sorting, and thus improving sorting efficiency.

[0044] When the melons fall onto the sorting plate 13, the sorting plate 13 causes the connecting plate 17 to rotate, and the torsion springs 15, which have different elastic potential energies, to rotate, depending on the weight of the melons. From left to right, the three pairs of torsion springs 15 have elastic potential energies of large, medium, and small, corresponding to melons of different weight ranges. Heavier melons cause the sorting plate 13 to rotate against the torsion springs 15 with greater elastic potential energy, while lighter melons cause the sorting plate 13 to rotate against the torsion springs 15 with less elastic potential energy, thus achieving the sorting of melons of different weights.

[0045] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
