DETAILED DESCRIPTION

[0014] In order to provide a further understanding of the purpose, structure, features, and functions of the present invention, the following detailed description is given in conjunction with the embodiments.

[0015] Please refer to Figure 1 The present invention provides a fully automatic fruit cleaning and sorting device, the device comprises a transmission structure, a cleaning structure and a sorting structure; the transmission structure comprises a transmission gear 3, a brush power rod 4, a transmission rod 5, a connecting rod 6, a motor 7, a motor pad 8 and a power rod 9; the cleaning structure comprises a water storage cover plate 1, a fruit inlet groove 2, a fruit storage bin 10, a central transport shaft 11, a brush 12 and a fruit outlet hole 17; the sorting structure comprises a screening bin 13, a fruit blocking plate 14, a spring 15, a screening disc 16 and a lower fruit hole 18; the central transport shaft 11 is provided with a spiral cone pattern; the fruit storage bin 10 drives the fruit to move in a spiral direction through the rotation of the central transport shaft 11; the water storage cover plate 1 stores cleaning water and introduces the water into the fruit storage bin 10 through the hole to clean the fruit together with the brush 12; the screening bin 13 sorts the fruit according to weight through the rotation of the screening disc 16; and the fruit is controlled to fall by the fruit blocking plate 14 and the spring 15.

[0016] The fully automatic fruit cleaning and sorting device completes the tasks of cleaning, sorting and processing fruits through the synergy of three main structures. The transmission structure is responsible for providing power, the cleaning structure ensures the cleanliness of the fruits, and the sorting structure accurately classifies the fruits according to their characteristics (such as weight). This device is highly automated and efficient, suitable for large-scale fruit processing, improving production efficiency and reducing the need for manual operation.

[0017] Preferably, the transmission gear 3 and the inner surface of the transmission rod 5 are matched with a gear rack; the incomplete gears at both ends of the brush power rod 4 are meshed with the racks on the outer surface of the transmission rod 5; the transmission rod 5 is connected to the power rod 9 through the connecting rod 6; the motor 7 provides power to the power rod 9; the motor pad 8 supports the motor 7; an incomplete bevel gear 19 is also provided on the end of the power rod 9; and a bevel gear 20 is also connected to the incomplete bevel gear 19.

[0018] The cooperation between the transmission gear 3 and the rack on the inner surface of the transmission rod 5 means that when the transmission gear 3 rotates, it will move along the rack on the inner surface of the transmission rod 5, so that the transmission rod moves in a straight line; when the transmission rod 5 moves, the rack on the inner surface of the transmission rod 5 will drive the transmission gear 3 to rotate; the incomplete gears at both ends of the brush power rod 4 mean that there is an incomplete gear at each end of the brush power rod, which may be an arc or partial gear (not a full gear ring); these incomplete gears are meshed with the rack on the outer surface of the transmission rod 5, indicating that the brush power rod plays a role in motion transmission in this system.

[0019] The function of the connecting rod 6 is to convert the linear motion of the transmission rod 5 into the motion of the power rod 9; this transmission mode allows the transmission rod 5 and the power rod 9 to work in coordination with each other, and then perform other actions, such as pushing, pushing and pulling, etc. The motor 7 is the core power source for driving the system, and the motor 7 usually provides power to the mechanical part through rotation or other forms of energy output. In the entire system, the function of the motor is to drive the power rod 9, and the power rod 9 transmits power to other parts through the connecting rod 6.

[0020] Preferably, the water storage cover plate 1 is installed above the fruit storage bin 10; the central transport shaft 11 is fixed to the central axis of the fruit storage bin 10 through the limiting holes at the front and rear ends of the fruit storage bin 10; the fruit outlet hole 17 is arranged at the end of the fruit storage bin 10, and a drainage hole is opened at the bottom; a layer of soft rubber pad is attached to the inner wall of the fruit storage bin 10; the front end of the central transport shaft 11 is fixedly coaxially matched with the transmission gear 3; the brush 12 is fixed to the fruit storage bin 10 through the limiting holes at the front and rear ends of the fruit storage bin 10; the front end of the brush 12 is fixedly coaxially matched with the brush power rod 4.

[0021] The fruit enters the device through the fruit inlet trough 2, and then enters the fruit storage bin 10, and is driven to move in a spiral direction by the rotation of the central transport shaft 11; during the movement, water is stored through the water storage cover 1 and guided to the cleaning area through the water holes, and the fruit is cleaned under the rotation of the brush 12; the cleaned fruit is discharged through the fruit outlet hole 17 and is ready to enter the sorting stage.

[0022] The function of the water storage cover plate 1 may be to prevent external water sources or pollutants from entering the fruit storage bin 10, and it may also be to maintain internal humidity or moisture. Installed above the fruit storage bin 10, it can avoid direct contact with the items in the fruit storage bin 10, ensuring that the fruits in the bin are not affected by the external environment during storage; the central transport shaft 11 is used to transmit power or serve as the rotating part of a mechanical device. By fixing with the limit hole, it is ensured that the central transport shaft 11 is stably docked with the central axis of the fruit storage bin 10. This design helps to keep the transport shaft running stably during operation, reduce axial deviation or vibration, and thus improve the stability and efficiency of mechanical operation.

[0023] The fruit outlet hole 17 is used to allow the fruit in the fruit storage bin to be discharged smoothly; the setting of the drainage hole effectively prevents water accumulation during the storage of the fruit, which causes the fruit to rot or deteriorate in quality. Through the drainage hole, the accumulated water can be discharged in time to ensure a dry storage environment, which is conducive to the long-term preservation of the fruit.

[0024] The soft rubber pad is mainly provided to prevent the fruit from directly contacting the inner wall of the fruit storage bin 10, thereby avoiding damage or squeezing of the fruit. The soft rubber material can provide a buffering effect, reduce the impact of collision on the fruit, and increase the service life of the fruit storage bin. In addition, the soft rubber material may have a certain moisture absorption function, further protecting the storage environment of the fruit.

[0025] The function of the brush 12 is to clean or scrub the fruit in the fruit storage bin, remove dust or debris on the surface, or shake and clean the fruit during transportation. The brush 12 is fixed by the limit hole to ensure that the brush 12 is stable and does not shift during operation, thereby avoiding affecting the cleaning effect. The coaxial matching design of the brush power rod 4 and the brush 12 ensures the effective transmission of power and ensures that the rotation or vibration function of the brush 12 can operate smoothly.

[0026] Preferably, two holes are provided at the bottom of the screening bin 13; one of the holes is used to place the fruit blocking plate 14 to allow large fruits to fall, and the other hole is not provided with the fruit blocking plate 14 to allow small fruits to fall; the fruit blocking plate 14 is fixed to the screening bin 13 by pins; the two ends of the spring 15 are respectively fixed to the inner surface of the screening bin 13 and the top of the groove of the fruit blocking plate 14, so that the fruit blocking plate 14 remains in a normally closed state; the screening disc 16 is installed on the central axis of the screening bin 13.

[0027] In each cycle, the motor 7 transports the fruits so that they fall into the guide U-shaped holes on the screening disc 16; the rotation of the motor 7 drives the rotation of the central transport shaft 11 and the power rod 9 at the same time, and the rotation of the central transport shaft 11 drives the fruits to move; the rotation of the power rod 9 drives the incomplete bevel gear 19 to rotate at the same speed, and the complete bevel gear 19 drives the bevel gear 20 to realize the rotation of the screening disc 16 to screen the fruits.

[0028] The washed fruits enter the screening bin 13 and are sorted by the rotation of the screening disc 16; the rotation of the screening disc enables the fruits to be sorted according to their weight or size; during the sorting process, the fruits are restricted by the fruit blocking plate 14 to ensure that only qualified fruits can fall into the designated position; the spring 15 can adjust the falling path or position of the fruits to help sort the fruits according to the required standards; finally, the fruits fall into the appropriate area or container through the fruit lowering hole 18, completing the entire sorting process.

[0029] A fruit blocker 14 is placed above one hole to intercept large fruits. The function of the fruit blocker 14 is to ensure that larger fruits cannot fall through the hole. Ensure that the larger fruits remain in the screening bin; the other hole is not provided with a fruit blocker 14, allowing smaller fruits to fall freely. Due to their smaller size, small fruits can easily fall through the hole without a fruit blocker to the collection area below; this design enables the screening process to effectively separate the fruits by size.

[0030] The screening disc 16 is mounted on the central axis of the screening bin 13. It is used to rotate or vibrate during the screening process, thereby helping the fruits to flow or vibrate more evenly, so that the fruits fall through different holes according to their sizes. The design of the screening disc 16 may help screen the material to ensure the uniform distribution of the fruits, or it may help the fruits to better contact the fruit baffle or screen by rotating or vibrating, thereby further ensuring the sorting effect; the fruit baffle 14 is kept in a normally closed state by a spring 15. The normally closed state means that when there is no external force, the fruit baffle 14 remains in a position to prevent large fruits from falling; the two ends of the spring 15 are fixed to the inner surface of the screening bin 13 and the top of the groove of the fruit baffle 14 to ensure that the fruit baffle 14 will not change position due to the collision or vibration of the fruit.

[0031] Preferably, the spring 15 maintains a normally closed state, and only when the weight of the fruit is greater than the elastic force of the spring 15, the fruit blocking plate 14 will open to allow the fruit to fall.

[0032] The function of the spring 15 is to provide an appropriate force to ensure that the position of the fruit blocking plate is stable and can react flexibly; the two ends of the spring 15 are respectively fixed to the inner surface of the screening bin 13 and the top of the groove of the fruit blocking plate 14. This design ensures that the fruit blocking plate 14 is in a normally closed state. When the fruit to be screened passes through the screening bin 13, the spring 15 provides a restoring force for the fruit blocking plate 14. If a large fruit contacts the fruit blocking plate 14, the spring 15 will be compressed to allow the large fruit to pass through; but when the fruit does not contact the fruit blocking plate 14, the spring 15 restores the fruit blocking plate 14 to its original position, thereby preventing the large fruit from continuing to pass through.

[0033] Preferably, the surface of the central transport shaft 11 is covered with a soft rubber layer.

[0034] Preferably, a method for a fully automatic fruit cleaning and sorting device, the specific steps of the method are as follows: S1: The motor drives the power rod, which drives the transmission rod to move through the connecting rod, and then drives the transmission gear to rotate and drive the brush; S2: The fruits are placed in the fruit storage bin, pushed forward by the central transport shaft, and washed with water and brushes, and the waste water is discharged; S3: The washed fruits are sorted in the screening bin according to their weight through the fruit baffles, and the larger fruits fall through the fruit holes.

[0035] Specific implementation: The fruit enters the fruit storage bin 10 through the fruit inlet groove 2; at this time, the fruit in the fruit storage bin 10 will follow the spiral cone pattern of the central transport shaft 11 and move in the spiral direction under the rotation of the shaft; the motor 7 in the transmission structure provides power, and drives the brush 12 to start working through the transmission gear 3, the connecting rod 6, the transmission rod 5 and the brush power rod 4; in the process of fruit movement, the water storage cover plate 1 above the fruit storage bin 10 introduces cleaning water into the fruit storage bin 10 through the water storage hole, and cleans the fruit together with the brush 12; the brush 12 rotates through the brush power rod 4 and contacts the surface of the fruit, effectively removing the dirt on the surface of the fruit; during the cleaning process, the soft rubber pad in the fruit storage bin 10 reduces friction and avoids damage to the fruit; after the fruit is cleaned, the fruit continues to move along the central transport shaft 11 through the action of the brush 12, and finally passes The fruit is discharged through the fruit outlet hole 17; there is a drainage hole at the bottom of the fruit outlet hole 17, and the cleaning water is discharged through the drainage hole to keep the device clean; the cleaned fruit enters the sorting stage; after the fruit enters the screening bin 13, the screening disc 16 starts to rotate, and the fruit is automatically sorted according to its weight; the fruit passes through the fruit baffle 14, and if the fruit is heavy, it falls directly, otherwise the fruit will continue to be transported until it falls into another hole without a fruit baffle; there are two holes at the bottom of the screening bin 13, one of which is equipped with a fruit baffle 14 to control the fall of larger fruits, and the other hole is without a fruit baffle 14, allowing smaller fruits to fall; the fruit baffle 14 is fixed in the screening bin 13 by a pin, and the spring 15 keeps the fruit baffle 14 in a normally closed state. Only when the fruit reaches a certain weight will the fruit baffle 14 be pressed by the spring to allow the fruit to fall. The two ends of the spring 15 are respectively fixed to the inner surface of the screening bin 13 and the top of the groove of the fruit blocking plate 14; the sorted fruits will fall into different collection areas according to their size and weight, realizing automatic sorting; large fruits fall through the fruit blocking plate 14, and small fruits fall through the holes without the fruit blocking plate. The whole process realizes automation from cleaning to sorting, greatly improving efficiency and accuracy.

[0036] The present invention has been described by the above-mentioned relevant embodiments, however, the above-mentioned embodiments are only examples for implementing the present invention. It must be pointed out that the disclosed embodiments do not limit the scope of the present invention. On the contrary, changes and modifications made without departing from the spirit and scope of the present invention are all within the scope of patent protection of the present invention.
