Description

Technical Field

[0001] This utility model relates to the field of fruit selection technology, and in particular to a fruit selection device for fruit tree packaging. Background Technology

[0002] Fruit selection is a process involving sensory and scientific methods, aimed at picking out the best quality fruit from a pile. It is often used in fruit packaging equipment to ensure that the fruit packaged by the equipment is of high quality and to prevent the appearance of spoiled fruit.

[0003] Therefore, in the existing fruit sorting device, disclosed in CN219943679U, fruits of different sizes are filled into the sorting device body through the feed inlet. Then, the first screen screens the falling fruits of different sizes. The first motor controls the sliding rod and the first gear at the other end to rotate. The first gear drives the second gear to rotate, so the threaded rod can drive the first screen through it to move vertically up and down, which speeds up the first round of fruit sorting. The large fruits that are sorted in the first round remain above the second screen. Then, the medium-sized fruits fall above the third screen due to gravity in the second round, and the smallest fruits fall into the collection box. The large and medium-sized fruits can be pushed to the discharge hopper by the push rod controlled by the hydraulic rod. The discharge hopper is equipped with a ramp so that the fruits can be discharged smoothly due to gravity. The collection mechanism is placed below the discharge hopper for unified collection.

[0004] However, during the movement of the first screen and the falling of the fruit from different layers of screen, the fruit will come into contact, rub and collide with each other, which can easily cause damage to the fruit surface, increase the rate of spoiled fruit, and affect the packaging speed of the subsequent fruit packaging machine. Utility Model Content

[0005] The purpose of this utility model is to solve the problems existing in the prior art by proposing a fruit sorting device for fruit tree packaging.

[0006] To achieve the above objectives, the present invention adopts the following technical solution: a fruit sorting device for fruit tree packaging, comprising several screening frames arranged side by side. Along the length of the screening frames, each screening frame has a slot on its inner wall. An insert is slidably installed in the slot. An anti-slip roller is rotatably connected to the long side of the upper surface of the insert away from the slot. The anti-slip roller is arranged along the length of the screening frame. A convex shaft penetrating both ends of the screening frame is fixedly connected to the side of the insert near the anti-slip roller at both ends. A lifting frame is inserted at the middle of the bottom edge of both ends of the screening frame. The lifting frame is located between two convex shafts on the same side of the screening frame. Two symmetrically distributed push-pull arms, each rotatably connected to the ends of two convex shafts on the same side, are rotatably connected inside the lifting frame.

[0007] Preferably, the filter frame has horizontally distributed T-shaped protrusions at both ends, and an insert rail is provided between the T-shaped protrusions on the same side of two adjacent filter frames.

[0008] Preferably, one end of each of the filtering frames is provided with a fruit-separating plate, and a fruit-separating channel is provided on the side of the fruit-separating plate corresponding to the position of each filtering frame. A receiving plate is provided below each of the filtering frames.

[0009] Preferably, the screening frame has horizontally hollowed-out areas at both ends that contact the convex shaft, a spring is provided between the inner wall of the slot and the side of the insert, and a spring is also provided on the upper surface of the insert near the anti-slip roller. The spring on the upper surface of the insert is inclined and its swinging edge abuts against the long side of the upper surface of the screening frame.

[0010] Preferably, the connection between the screening frame and the lifting frame is also T-shaped and vertically distributed, and a vertically arranged electric push rod for pushing the lifting frame to rise and fall is fixedly connected to the screening frame.

[0011] Preferably, both ends of the anti-slip roller are fixedly installed with driven pulleys that extend outward through the insert strips. The upper surface of the screening frame is connected to two driven pulleys on the same side with insert plates inserted between them. One side of the insert plate is rotatably connected to a driving pulley, and the middle of the other side is connected to the screening frame with vertically distributed spring rods.

[0012] Preferably, the active pulley on the same side of the screening frame is connected to two driven pulleys via a belt drive, and the active pulley is driven by a motor.

[0013] Compared with the prior art, the advantages and positive effects of this utility model are as follows:

[0014] 1. In this utility model, by setting a screening frame, the fruits are arranged in a linear pattern within the screening frame using two anti-slip rollers. By adjusting the distance between the two anti-slip rollers, the fruits can be collected in an orderly manner from small to large, ensuring that the fruits do not collide during the falling process, thereby reducing the rate of spoiled fruits.

[0015] 2. In this utility model, the motor drives the active pulley to rotate, which in turn drives the two driven pulleys to rotate the corresponding anti-slip rollers under the transmission action of the belt. This enables the two anti-slip rollers in the screening frame to rotate in the same direction and at the same speed, and enables the fruit located between the two anti-slip rollers to rotate. This facilitates visual inspection or scanning of the fruit surface by personnel to judge the quality of the fruit. Attached Figure Description

It should be noted that, unless otherwise specified, the embodiments and features described in these embodiments can be combined with each other.

[0022] Many specific details are set forth in the following description in order to provide a full understanding of the present invention. However, the present invention may also be implemented in other ways different from those described herein. Therefore, the present invention is not limited to the specific embodiments disclosed in the following specification.

[0023] like Figure 1-4 As shown;

[0024] A fruit sorting device for fruit tree packaging includes several screening frames 3 arranged side by side. Along the length of each screening frame 3, a slot 16 is provided on the inner wall of each screening frame 3. An insert 14 is slidably installed in the slot 16. An anti-slip roller 6 is rotatably connected to the long side of the upper surface of the insert 14 away from the slot 16. The anti-slip roller 6 is arranged along the length of the screening frame 3. A convex shaft 13 penetrating both ends of the insert 14 is fixedly connected to the side of the insert 14 closest to the anti-slip roller 6. A lifting frame 11 is inserted into the middle of the bottom edge of each end of the screening frame 3. The insertion part of the screening frame 3 and the lifting frame 11 is also T-shaped and vertically distributed. A vertically arranged electric push rod 10 for pushing the lifting frame 11 to rise and fall is fixedly connected to the screening frame 3. The lifting frame 11 has two convex shafts 13 on the same side of the screening frame 3. Between them, there are two symmetrically distributed push-pull arms 12 rotatably connected inside the lifting frame 11, which are respectively rotatably connected to the ends of two convex shafts 13 set on the same side. In actual use, the lifting frame 11 is raised and lowered against both ends of the screening frame 3 by using the extension and retraction of the electric push rod 10. By using the sliding connection between the convex shafts 13 and the ends of the screening frame 3, the distance between the two convex shafts 13 can be adjusted under the connection of the push-pull arms 12 when the lifting frame 11 is raised and lowered. In turn, the distance between the two anti-slip rollers 6 inside the screening frame 3 can be adjusted. By gradually increasing the distance, it is easy to make the fruits fall one by one from small to large. And because the fruits are arranged in a linear shape along the length of the screening frame 3 when they are between the two anti-slip rollers 6, it can be ensured that the fruits will not collide with each other when they fall between the two anti-slip rollers 6.

[0025] Furthermore: both ends of the filter frame 3 are provided with horizontally distributed T-shaped protrusions, and the T-shaped protrusions on the same side of two adjacent filter frames 3 are fitted with insert rails 15. By inserting the insert rails 15 into the joint of two adjacent filter frames 3, it can be ensured that the upper surfaces of the two adjacent filter frames 3 are flush and will not be bent. In addition, in actual operation, screws or bolts can be used to connect the insert rails 15 and the filter frames 3.

[0026] Furthermore: Several screening frames 3 are provided with a fruit-separating plate 1 at one end, and a fruit-separating channel 2 is provided on the side of the fruit-separating plate 1 corresponding to the position of each screening frame 3. A receiving plate 4 is provided below several screening frames 3. The fruit-separating plate 1 is used to spread a certain amount of fruit flat, and the fruit slides down one by one through the fruit-separating channel 2 into the two anti-slip rollers 6 in the corresponding screening frame 3. The receiving plate 4 can accept fruits of different sizes that fall from the screening, and by laying sponge or other shock-absorbing and soft materials on the bottom of the receiving plate 4, it can be ensured that the fruits will not be damaged when they fall.

[0027] Furthermore, the horizontally hollowed-out areas at both ends of the screening frame 3, which are in contact with the convex shaft 13, ensure that the convex shaft 13 can only slide horizontally within the screening frame 3. A spring piece 5 is provided between the inner wall of the slot 16 and the side of the insert 14. The spring piece 5 here can help the two anti-slip rollers 6 in the screening frame 3 to move closer to each other. Specifically, when the two anti-slip rollers 6 move away from each other, the corresponding insert 14 will move away from each other, and the corresponding spring piece 5 will bend and deform elastically. Therefore, when the lifting frame 11 descends, the elastic reset of the spring piece 5 can push the insert 14 and the anti-slip roller 6 to reset. A spring piece 5 is also provided on the upper surface of the insert 14 near the anti-slip roller 6. The spring piece 5 on the upper surface of the insert 14 is inclined and its swinging edge abuts against the long side of the upper surface of the screening frame 3, ensuring that the fruit passing through the fruit separation channel 2 will not fall on both sides of the two anti-slip rollers 6.

[0028] Furthermore: Driven pulleys 8 are fixedly installed at both ends of the anti-slip roller 6, extending outwards from the insert strip 14. An insert plate 9 is inserted between the two driven pulleys 8 on the same side of the upper surface of the screening frame 3. A drive pulley 7 is rotatably connected to one top edge of the insert plate 9, and a vertically distributed spring rod 17 is connected between the middle of the other side and the screening frame 3. The drive pulley 7 on the same side of the screening frame 3 is driven by a belt, and the drive pulley 7 is driven by a motor. By rotating the drive pulley 7, the two driven pulleys 8 can be driven by the belt, thus achieving the screening function. The two anti-slip rollers 6 inside frame 3 rotate in the same direction and at the same speed, which enables the fruit located between the two anti-slip rollers 6 to rotate. This facilitates visual inspection or scanning of the fruit surface by personnel to judge the quality of the fruit. In addition, the insert plate 9 and spring rod 17 used in this solution can also be used to drive the insert plate 9 to overcome the thrust of the spring rod 17 and descend when the distance between the two anti-slip rollers 6 increases, ensuring that the belt is kept taut. Similarly, by utilizing the elastic extension of the spring rod 17, when the distance between the two anti-slip rollers 6 decreases, the insert plate 9 will drive the drive belt wheel 7 to rise under the elastic extension of the spring rod 17, ensuring that the belt is taut and will not fall.

[0029] Working principle: When in use, the fruit is placed on the fruit-separating tray 1 and laid flat. It then slides down one by one along several fruit-separating channels 2 into the two anti-slip rollers 6 in the corresponding screening frame 3. The two anti-slip rollers 6 rotate at the same speed and in the same direction using the belt drive, thereby turning the fruit over so that people can visually pick out the fruit with surface damage. Then, the electric push rod 10 is used to extend and retract to make the lifting frame 11 rise along both ends of the screening frame 3. With the sliding connection between the convex shaft 13 and the end of the screening frame 3, and the connection action of the push-pull arm 12, the distance between the two convex shafts 13 gradually increases as the lifting frame 11 rises, which makes it easy for the fruit to fall one by one from small to large and be collected in the receiving tray 4.

[0030] The wiring diagrams of the electric actuator 10 and the motor in this utility model are common knowledge in the field. Their working principle is a well-known technology. The appropriate model is selected according to actual use. Therefore, the control method and wiring layout of the electric actuator 10 and the motor will not be explained in detail.

[0031] The above description is merely a preferred embodiment of the present utility model and is not intended to limit the present utility model in any other way. Any person skilled in the art may make changes or modifications to the above-disclosed technical content to create equivalent embodiments for application in other fields. However, any simple modifications, equivalent changes, and modifications made to the above embodiments based on the technical essence of the present utility model without departing from the technical solution of the present utility model shall still fall within the protection scope of the technical solution of the present utility model.
