Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of fruit selection equipment, in particular to a fruit selection device for screening pomegranates. Background Art
[0002] Pomegranate is a deciduous tree or shrub. Its leaves are simple, usually opposite or clustered, without stipules. Its flowers are terminal or subterminal, solitary or in clusters or cymes. They are nearly bell-shaped, with 5-9 lobes and 5-9 petals, often wrinkled and imbricate. The ovules are numerous. The berries are spherical, with persistent calyx lobes at the apex and a thick pericarp. The seeds are numerous, nearly spherical, and ripen in September-October. The outer seed coat is translucent and juicy, while the inner seed coat is leathery. After ripening, pomegranates are often sorted using a sorting device to separate the fruits by size.
[0003] Currently, pomegranates are generally screened by visual inspection to classify pomegranates of different sizes. Another method is screening, which uses a sieve plate with multiple holes of different sizes distributed on the sieve plate. The pomegranates are classified through the holes of different sizes. However, the size of the holes on the sieve plate is basically fixed. If the pomegranate is too large or too small, it is easy to cause the pomegranate to get stuck, thereby affecting the normal classification of the pomegranate. Utility Model Content

[0033] See also Figures 1-4 A pomegranate screening device includes a first base 1 and a second base 2. A groove 3 is opened on one side of the first base 1 and the second base 2. The bottom end of the inner groove 3 of the first base 1 is symmetrically connected to a rotating rod 4, and the surface of the rotating rod 4 is connected to a gear 5, and the surface of the rotating rod 4 is connected to a conveying roller 6; the inner groove 3 is rotatably connected to a screw 7, and the two sides of the surface of the screw 7 are respectively threadedly connected to connecting strips 8, and the surface of the connecting strip 8 is connected to a rack 9; the bottom end of the conveying roller 6 is provided with a plurality of collecting boxes 10 The inclined conveying rollers 6 are used to facilitate the conveying of pomegranates. When the diameter of the pomegranate is smaller than the gap between the two conveying rollers 6, the pomegranate will fall from the gap into the inside of the collection box 10. The protective pad 18 provided inside the collection box 10 can cushion the falling pomegranates. After the protective pad 18 is hit, the baffle 17 at its bottom will be flipped by the rotating tube 16, causing the pomegranate to fall into the inside of the collection box 10 and then pass through the guide plates 19 on both sides of the collection box 10 to be guided to the inner center of the collection box 10.
[0034] See also Figure 1 A partition 11 for blocking pomegranates is provided at the top of the conveyor roller 6. The partition 11 prevents the pomegranates from falling from the surface of the conveyor roller 6 when being conveyed on the surface of the conveyor roller 6. The partition 11 can be used to block the pomegranates and prevent them from falling.
[0035] See also Figure 2 The rack 9 and the surface of the gear 5 are meshed and connected, so that when the rack 9 moves on the surface of the gear 5, the gear 5 can drive the rotating rod 4 and the conveying roller 6 to rotate, thereby adjusting the distance between the two conveying rollers 6 to facilitate adjustment according to the size of the pomegranate.
[0036] See also Figure 2 A slide groove 12 is provided on the inner wall of the groove 3 on the surface of the first base 1, and a slider 13 is slidably connected to the inside of the slide groove 12, and one side of the slider 13 is connected to a connecting rod 14 connected to one side of the connecting bar 8. The slider 13 and the slide groove 12 are convenient for the screw 7 to drive the connecting bar 8 to move, and the connecting bar 8 can be limited and moved inside the slide groove 12 through the slider 13, and the connecting rod 14 is convenient for connecting the connecting bar 8 and the slider 13.
[0037] See also Figure 1 A loading chute 15 is inclined at the top of the first base 1. The inclined loading chute 15 is convenient for conveying the pomegranates between the two conveying rollers 6. The pomegranates can be conveyed by the two inclined conveying rollers 6. After being conveyed to the designated position, the pomegranates can fall into the designated collection box 10. That is, when the diameter of the pomegranate is smaller than the distance between the two conveying rollers 6, the pomegranates will fall into the collection box 10 through the gap between the two conveying rollers 6.
[0038] See also Figure 1 The inner wall of the collection box 10 is rotatably connected to a rotating tube 16, and the surface of the rotating tube 16 is connected to a baffle 17, and a protective pad 18 is provided on the top of the baffle 17. The protective pad 18 prevents the pomegranate from falling directly onto the surface of the baffle 17, causing a collision between them, which may easily damage the pomegranate. The baffle 17 and the rotating tube 16 are convenient for flipping and moving, so that after the pomegranate falls onto the surface of the protective pad 18, the baffle 17 can be flipped and moved by the rotating tube 16 under force, so that the pomegranate can roll into the interior of the collection box 10.
[0039] See also Figure 3 Guide plates 19 are arranged obliquely on both sides of the inner wall of the collection box 10. The guide plates 19 are used to guide the pomegranates that fall on both sides of the inner wall of the collection box 10 to the inner center of the collection box 10, so as to avoid the pomegranates from piling up on both sides of the inner wall of the collection box 10, thereby affecting the subsequent flipping of the baffle 17.
[0040] See also Figure 4 A fixing rod 20 and a torsion spring 21 are respectively provided inside the rotating tube 16. The torsion spring 21 is used to facilitate resetting the rotating tube 16 and the baffle 17.
[0041] See also Figure 2 The threads on both sides of the surface of the screw 7 are set in opposite directions, so that when the screw 7 rotates, the connecting strips 8 on both sides of its surface move towards or away from each other at the same time, so that the gears 5 on one side of the two connecting strips 8 can rotate in opposite directions.
[0042] Working principle: When in use, first put the pomegranate into the feeding chute 15, and the pomegranate inside can be rolled onto the surface of the two conveying rollers 6 by the inclined feeding chute 15. The pomegranate can be conveyed by the inclined conveying rollers 6. When the pomegranate moves to the specified position, that is, when the diameter of the pomegranate is smaller than the distance between the two conveying rollers 6, the pomegranate can be dropped to the top of the protective pad 18 inside the collecting box 10. The protective pad 18 can cushion the falling pomegranate to avoid collision between the pomegranate and other objects, which may cause damage to the pomegranate. After the protective pad 18 is subjected to the impact force, the baffle 17 at the bottom end of the protective pad 18 can be flipped and moved by the rotating tube 16, and the pomegranate on the top of the protective pad 18 can be flipped to one side of the collecting box 10, and then passed through the collecting box 10. The guide plates 19 on both sides of the inner wall are used to guide the pomegranates on both sides to the inner center of the collection box 10 to prevent the pomegranates from piling up on both sides of the collection box 10 and affecting subsequent collection. When it is necessary to adjust the distance between the two conveying rollers 6 according to the size of the pomegranate, the screw 7 can be rotated to allow the connecting strips 8 on both sides of its surface to be limited and moved through the connecting rod 14, the slider 13 and the slide groove 12, so that the connecting strip 8 can drive the rack 9 to move on the surface of the gear 5, so that the gear 5 can drive the rotating rod 4 and the conveying roller 6 connected thereto to rotate, so that the distance between the two conveying rollers 6 can be adjusted according to the different sizes of pomegranates, so that when the diameter of the pomegranate is less than the distance between the two conveying rollers 6, it can fall into the designated collection box 10 for collection.
