[0002] Pear sorting is an important link in agricultural production. It ensures that pears are classified according to standards such as quality, size, and maturity, thereby improving the market competitiveness and economic benefits of products. Currently, mechanical automation sorting equipment is often used in the market to sort pears by size for better subsequent processing of pears;
[0003] In the existing technical solutions, when pears are sorted on a sorting machine, conveyor rollers with different spacings are usually used for sorting. As the conveyor belt moves, the pears gradually fall through the gaps between the conveyor rollers into the corresponding collection boxes. However, the pears fall from a relatively high position, and the impact force when landing is large. The strong impact may cause damage to the internal structure of the pears, accelerate the decay process, shorten the shelf life, and the collision may also cause bruises, scratches or indentations on the surface of the pears, thus affecting their appearance and product quality.
[0004] In view of this, we propose a pear sorting device. Utility Model Content

Detailed implementation manners
[0023] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present utility model.
[0024] Referring to Figure 1 , a pear sorting device provided by this application includes a base 1. A controller is installed on the base 1. Above the base 1, there are a feeding component and a sorting component. The feeding component includes a feeding conveyor belt 2, a feeding hopper 3 installed at one end of the feeding conveyor belt 2, and a discharging hopper 4 installed at the other end of the feeding conveyor belt 2. The sorting component is arranged below the discharging hopper 4. The sorting component includes a sorting machine 5. Among them, the sorting machine 5 includes conveying rollers. The conveying rollers are usually composed of a series of parallel rollers, and the spacing between the rollers can be adjusted according to the size of the pears. The rollers are driven by a motor, sprockets, chains, etc. The pears gradually pass through the gaps between the conveying rollers, and the pears are sorted into different areas according to their sizes. Since both the feeding conveyor belt 2 and the sorting machine 5 are prior arts, they will not be described in detail here;
[0025] Referring to Figures 1 - 5 , below the sorting machine 5, there is an aggregate component, and there are three groups of aggregate components. Each group of aggregate components includes a material receiving box 6, a channel 7, and a collection box 8. Among them, the material receiving box 6 and the collection box 8 are connected through the channel 7, and the material receiving box 6, the channel 7, and the collection box 8 are integrally designed. Both sides at one end of the channel 7 are designed to be inclined inward. This design can facilitate the guiding of the pears. Among them, a support seat is fixed at the bottom end of the inner wall of the material receiving box 6. The support seat is inclined towards the direction of the channel 7. Above the support seat, a number of brush rollers 9 are rotatably connected. When the pears are fed onto the brush rollers 9, it plays a role of buffering and decelerating. And both ends of each group of brush rollers 9 are rotatably connected to the inner wall of the material receiving box 6 through bearings. When the pears roll and fall on the surface of the brush rollers 9, the brush rollers 9 can wipe the surface of the pears, thereby playing a role in cleaning the pears;
[0026] It should be noted that a guiding plate 10 is rotatably provided in the middle of one end of the channel 7 close to the collecting box 8. The guiding plate 10 is used to guide and disperse the pears. A rotating shaft 11 is fixed to the inner wall of the guiding plate 10. The bottom end of the rotating shaft 11 is rotatably connected to the inner wall of the channel 7 through a bearing. A support frame 12 is detachably installed above one end of the channel 7 close to the collecting box 8. The detachable installation method can be bolt connection. An electric push rod 13 is installed on the upper surface of the support frame 12. The electric push rod 13 is electrically connected to the controller. A rack plate 14 is fixed to the output end of the electric push rod 13. A slider is fixed to the bottom end of the rack plate 14. The slider can be limited and slide in a chute opened on the inner wall of the support frame 12. The rack plate 14 can be used to limit the movement of the electric push rod 13. The top end of the rotating shaft 11 penetrates through the support frame 12 and is fixed with a gear 15. The gear 15 is meshed with the rack plate 14. By controlling the electric push rod 13, the rack plate 14 can be driven to move back and forth to control the rotation of the rotating shaft 11 and the guiding plate 10 by the gear 15, and then control the guiding plate 10 to swing back and forth to play a role in guiding the pears. By changing the movement track of the pears, not only can the number of pears piled up together be reduced, but also the sorting speed of the pears can be reduced, and continuous collisions caused by the fast speed when the pears converge can be avoided.
[0027] Wherein, both sides of the bottom end inner wall of the collecting box 8 are fixed with deceleration belts 17. The deceleration belts 17 are used to decelerate the pears. The deceleration belts 17 can further decelerate the pears after they are dispersed by the guiding plate 10, so as to improve the quality of the sorted pears.
[0028] It should be noted that a first rubber pad 16 is adhesively fixed to the outer wall of one side of the guiding plate 10 close to the material receiving box 6, and a second rubber pad 18 is adhesively fixed to the inner wall of the collecting box 8. Both the first rubber pad 16 and the second rubber pad 18 can play a role in buffering and protecting the pears.
[0029] The implementation principle of a pear sorting device according to an embodiment of the present application is as follows:
[0030] First of all, the pears are poured into the feeding hopper 3, and with the continuous transmission of the feeding conveyor belt 2, the pears enter the sorting machine 5 through the discharging hopper 4 for sorting. The pears gradually pass through the gaps between the conveying rollers and fall into the corresponding material receiving boxes 6. When the pears fall into the material receiving boxes 6, they contact a number of brush rollers 9. When the brush rollers 9 rotate, they can convey the pears and wipe the surfaces of the pears at the same time.
[0031] Secondly, when the pear comes to the inside of the channel 7 after passing through the brush roller 9, the electric push rod 13 is started at this time. The electric push rod 13 is used to control the movement of the rack plate 14, drive the rotation of the gear 15, the gear 15 drives the rotation of the rotating shaft 11, so that the guide plate 10 swings back and forth, guides the pear and changes the movement track of the pear, reduces the sorting speed. At the same time, after the pear enters the collection box 8 through the guide plate 10, it is decelerated again through the speed reducer 17.
[0032] The above are all the preferred embodiments of this application. The protection scope of this application is not limited accordingly. Therefore, all equivalent changes made according to the structure, shape and principle of this application should be covered within the protection scope of this application.
