Technical Field

[0001] This utility model relates to the field of pomelo sorting technology, and in particular to an automatic pomelo grading device. Background Technology

[0002] The pomelo is a plant of the genus Citrus in the family Rutaceae. It is distributed in regions south of the Yangtze River in China and Southeast Asia. Its young branches, the back of the leaves, the pedicels, the calyx and the ovary are all covered with soft hairs. The young leaves are usually dark purplish-red. The young branches are flat and angular. The leaves are quite thick, dark green, and broadly ovate or elliptical. The inflorescence is a raceme, sometimes with axillary solitary flowers. The flower buds are pale purplish-red, rarely milky white.

[0003] In the existing technology, pomelos need to be packaged and sold after harvesting. However, due to the difficulty in distinguishing between unripe and ripe fruits during mechanical harvesting, and the possibility of fruits being crushed or damaged during transportation, the existing technology can only classify fruits by size. Therefore, it is easy for defective fruits to be mixed in when the product is being packaged. Utility Model Content

[0004] In view of the shortcomings of the existing technology, the purpose of this utility model is to provide an automatic grading device for pomelos, so as to solve the technical problems mentioned in the background art.

Detailed Implementation

[0022] The present invention will be further described in detail below with reference to the accompanying drawings.

[0023] Example:

[0024] Reference Figure 1 - Figure 4 The present invention discloses an automatic grading device for pomelos, including a collection frame 1, a sliding roller 2 slidably disposed on the upper end of the collection frame 1, an inlet frame 3 disposed on one end of the collection frame 1 above the sliding roller 2, a roller adjustment structure 4 disposed on the front end of the collection frame 1, and a storage frame 5 disposed on the end of the collection frame 1 away from the inlet frame 3.

[0025] Two sliding rollers 2 are provided, and sliding blocks 6 are rotatably provided at both ends of the sliding rollers 2. The sliding blocks 6 are slidably provided at the edge of the collection frame 1. The outer peripheral wall of the sliding rollers 2 is provided with guide threads 7, and the spiral directions of the guide threads 7 provided on the outer peripheral walls of the two sliding rollers 2 are opposite.

[0026] In this embodiment, when in use, grapefruits of the same size are put into the top of the inlet frame 3, and the distance between the two sliding rollers 2 is adjusted by the roller adjustment structure 4 so that the distance between the two sliding rollers 2 is slightly smaller than the diameter of the grapefruit. At this time, the grapefruit falls between the two sliding rollers 2 after being guided by the inlet frame 3. The sliding rollers 2 are then driven to rotate relative to each other, and the grapefruit is pushed to move by the guide thread 7 on the outside of the sliding rollers 2. During the movement of the grapefruit, bad and unripe fruits are removed.

[0027] Specifically, in the existing technology, the problem of rotten pomelo fruit is that the pulp rots. The rotten pulp will cause the pomelo to soften and there will be obvious indentation and collapse when pressed. Therefore, when the sliding roller 2 rotates relative to each other, it will cause the rotten pomelo fruit to deform and squeeze the rotten fruit out between the two sliding rollers 2, so as to achieve the purpose of expelling the rotten fruit.

[0028] The rougher surface of the unripe pomelo with uneven spots greatly increases the friction with the sliding roller 2. Furthermore, when pressing the unripe pomelo peel, the peel is softer and easily dents. As the sliding roller 2 rotates relative to each other, the unripe pomelo deforms and is squeezed out between the two sliding rollers 2, thus achieving the purpose of expelling the unripe pomelo.

[0029] When you press a ripe pomelo, the plump fruit has a certain elasticity and feels firm. The ripe pomelo is also relatively round, so it can roll well between the two sliding rollers 2, which makes it easier to enter the storage box 5 through the push of the guide screw 7.

[0030] In a further preferred embodiment of this utility model, such as Figure 1-4 As shown, the roller adjustment structure 4 includes a side plate 401. Two side plates 401 are provided and are respectively provided on both sides of the guide frame 3. An adjustment shaft 402 is rotatably provided between the two side plates 401. The two ends of the adjustment shaft 402 are provided with adjustment threads 403, and the two sets of adjustment threads 403 are arranged opposite to each other. Two sets of adjustment sliders 404 are threadedly connected to the outer peripheral wall of the adjustment shaft 402. The two sets of adjustment sliders 404 are respectively fixedly connected to two sliding blocks 6.

[0031] In this embodiment, by rotating the adjusting shaft 402, the adjusting sliders 404 at both ends of the adjusting shaft 402 can move synchronously, so that the adjusting sliders 404 can move relative to each other, thereby controlling the sliding block 6 to slide on the edge of the collection frame 1, thereby adjusting the gap between the two sliding rollers 2, so that the device can grade pomelos of different sizes.

[0032] In a further preferred embodiment of this utility model, such as Figure 1-4 As shown, a sliding groove 101 is provided on the bottom side of the collection frame 1, and an inclined plate 102 is provided inside the collection frame 1, with the inclined plate 102 facing the sliding groove 101.

[0033] In this embodiment, by setting the sliding groove 101, when the rotten fruit and the unripe fruit pass between the two sliding rollers 2 and fall into the collection frame 1, the tilting plate 102 guides the rotten fruit and the unripe fruit to be discharged through the sliding groove 101.

[0034] In a further preferred embodiment of this utility model, such as Figure 1-4 As shown, the storage frame 5 is provided with an anti-collision net 501 inside. The anti-collision net 501 is concave and elastic. The bottom end of the anti-collision net 501 is provided with a hole 502.

[0035] In this embodiment, the anti-collision net 501 is used to buffer the ripe fruit when it falls into the storage box 5, so as to prevent the ripe fruit from being damaged.

[0036] In a further preferred embodiment of this utility model, such as Figure 1-4 As shown, the top of the adjusting slider 404 is provided with a drive motor 8, and the motor shaft of the drive motor 8 is fixedly connected to the end of the sliding roller 2.

[0037] In this embodiment, the drive motor 8 is used to drive the sliding roller 2 to rotate.

[0038] In a further preferred embodiment of this utility model, such as Figure 1-4 As shown, a guide platform 503 is provided at the top of the storage frame 5 and between the two sliding rollers 2.

[0039] In this embodiment, the guide platform 503 is arc-shaped and extends into the interior of the storage frame 5. The guide platform 503 guides the grapefruit falling into the storage frame 5.

[0040] The embodiments described herein are preferred embodiments of this utility model and are not intended to limit the scope of protection of this utility model. Therefore, all equivalent changes made to the structure, shape, and principle of this utility model should be included within the scope of protection of this utility model.
