[0002] As people pursue a higher quality of life, more and more people are demanding higher quality fruits and vegetables, making automated sorting of fruits and vegetables an important technology.

[0003] In automated fruit and vegetable sorting, fruits and vegetables are placed in fruit cups, which are then transported by a conveyor assembly to different devices where they undergo various processing steps. Finally, the fruits and vegetables in the cups are conveyed to different sorting channels to complete the sorting process. As the fruits and vegetables move between different conveyor units, they may change direction, requiring interception and guidance. This is typically achieved using a roller brush device.

[0004] However, existing roller brush devices often have multiple sets of roller brushes installed. After prolonged contact with fruits and vegetables, the roller brushes are prone to wear and tear, requiring the complete removal of the transmission components on the roller brushes for replacement. This results in a large workload and long time for disassembly and installation, affecting production efficiency. Utility Model Content

The terminology used in this specification is for the purpose of describing particular embodiments only and is not intended to limit the scope of the invention.

[0046] Please refer to the following: Figure 1 and Figure 2 , Figure 1 This is a schematic diagram of the structure of a roller brush assembly provided in one embodiment of the present invention; Figure 2 yes Figure 1 An exploded view of the drive rollers and drums in the diagram.

[0047] An embodiment of this utility model provides a roller brush assembly 100, including roller brush components 10, rollers 20, drive rollers 30, and fasteners 40. Multiple roller brush components 10 are provided, each sleeved on the roller 20 and spaced apart. The roller 20 has a receiving cavity 21 that extends through it. One end of the roller 20 has a mounting groove 22 that connects the receiving cavity 21 to the outside. One end of the drive roller 30 is used to connect to a drive device, and the other end of the drive roller 30 extends into the receiving cavity 21. The fasteners 40 are connected to the end of the drive roller 30 near the roller 20. The end of the fasteners 40 facing away from the drive roller 30 abuts against the wall of the mounting groove 22, so that when the drive roller 30 rotates, the fasteners 40 can drive the drive roller 20 to rotate.

[0048] Specifically, during the installation of the drive roller 30, a fastener 40 is installed at one end of the drive roller 30, with one end of the drive roller 30 passing through the roller 20 along its axial direction. The fastener 40 is aligned with the mounting groove 22 so that it abuts against the groove wall, ensuring that the fastener 40 abuts against the roller 20 while the drive roller 30 rotates, thus driving the roller 20 to rotate. During the installation and disassembly of the drive roller 30, the drive roller 30 is detached from the roller 20 along its axial direction. This achieves the effect of quick installation and disassembly of the drive roller 30 and the roller 20. The mounting groove 22 is a U-shaped groove.

[0049] It should be noted that the drive device can drive the transmission roller 30 to rotate, and the fastener 40 rotates together with the transmission roller 30. The fastener 40 abuts against the wall of the mounting groove 22 of the roller 20. The fastener 40 drives the roller 20 to rotate together, and the roller brush 10 on the roller 20 also rotates. The roller brush 10 blocks and buffers the fruits and vegetables, and plays a protective role on the surface of the fruits and vegetables to prevent damage to the surface of the fruits and vegetables. When the roller brush 10 rotates, it moves relative to the surface of the fruits and vegetables to guide the fruits and vegetables and prevent the fruits and vegetables from stopping and accumulating on one side of the roller brush 10.

[0050] In one embodiment, the drive roller 30 has a threaded hole 31 at the end near the drum 20, and the fastener 40 is partially received in the threaded hole 31 and threadedly connected to the threaded hole 31. The end of the fastener 40 abuts against the groove wall of the mounting groove 22.

[0051] Specifically, the fastener 40 is a cup-head bolt. One end of the fastener 40 is threadedly connected to the transmission roller 30, and the other end of the fastener 40 abuts against the groove wall of the mounting groove 22. When the roller 20 rotates, the end of the cup-head bolt provides the torque drive source.

[0052] In this embodiment, the end of the transmission roller 30 near the drum 20 is provided with an abutment surface 32. The abutment surface 32 is a planar structure. The fastener 40 near the bottom of the transmission roller 30 abuts against the abutment surface 32 to ensure that the end face of the fastener 40 is placed horizontally.

[0053] In another embodiment, the fastener 40 and the drive roller 30 are an integral structure, and the fastener 40 extends radially along the drive roller 30.

[0054] Specifically, this can reduce the number of steps required to install the fastener 40 onto the drive roller 30, further improving the efficiency of installation and disassembly between the drive roller 30 and the drum 20.

[0055] See Figure 3 , Figure 4 and Figure 5 , Figure 3 yes Figure 1 A schematic diagram of the middle roller brush assembly from another angle; Figure 4 yes Figure 3 Enlarged structural diagram of section A; Figure 5 yes Figure 1 A schematic diagram of the structure of the middle roller brush component.

[0056] In one embodiment, each roller brush 10 includes a mounting portion 11 and a roller brush portion 12. The roller brush portion 12 is arranged around the circumferential surface of the mounting portion 11. The mounting portion 11 has a mounting cavity 111. The roller 20 passes through the mounting cavity 111 to connect the roller brush 10 with the roller 20. The end of the fastener 40 facing away from the drive roller 30 protrudes from the mounting groove 22. The mounting portion 11 has a clearance groove 112 that communicates with the mounting cavity 111. The clearance groove 112 of one roller brush 10 near the drive roller 30 receives the end of the fastener 40 facing away from the drive roller 30.

[0057] Specifically, the end of the fastener 40 facing away from the drive roller 30 can be accommodated in the relief groove 112 so that the roller brush 10 is installed in a direction close to the drive roller 30, thereby reducing the gap between the roller brush 10 and the frame 210 during actual operation; if there is a gap between a roller brush 10 located on the roller 20 and close to the drive roller 30 and the frame 210, it may cause fruits and vegetables to accumulate in the gap.

[0058] In addition, the roller brush 12 is a brush, and the roller brush 12 can be installed on the circumferential surface of the mounting part 11 by means of Velcro. The roller brush 12 extends outward along the radial direction of the mounting part 11. When the roller brush 12 is rotated, it moves relative to the surface of the fruit and vegetables to guide the movement of the fruit and vegetables.

[0059] In one embodiment, each roller brush 10 further includes a protrusion 13, and a plurality of protrusions 13 are provided. The plurality of protrusions 13 are arranged circumferentially around the cavity wall of the mounting cavity 111, and a clearance groove 112 is provided between two adjacent protrusions 13. The protrusions 13 abut against the surface of the roller 20.

[0060] Specifically, a clearance groove 112 is formed between two adjacent protrusions 13, increasing the number of clearance grooves 112 to improve the alignment efficiency between the clearance grooves 112 and the end of the fastener 40. Moreover, the protrusions 13 abut against the surface of the roller 20, which can increase the contact area between the roller brush 10 and the roller 20, improve the friction between the roller brush 10 and the roller 20, and ensure that the roller brush 10 is installed more securely.

[0061] In this embodiment, the protrusion 13 and the mounting portion 11 are integrated, which can reduce the manufacturing cost of the roller brush 10. One end of the protrusion 13 is connected to the inner wall of the mounting portion 11, and the other end of the protrusion 13 extends radially along the axis of the roller brush 10. Multiple protrusions 13 are evenly spaced along the circumference of the mounting cavity 111 on the cavity wall of the mounting cavity 111, and a clearance groove 112 is formed between two adjacent protrusions 13.

[0062] In one embodiment, the mounting part 11 has a first mounting hole 113, which connects the mounting cavity 111 to the outside. The roller 20 has a second mounting hole 23, which connects the receiving cavity 21 to the outside. There are multiple second mounting holes 23, which are spaced apart along the length of the roller 20. The first mounting hole 113 of each roller brush 10 is connected to a corresponding second mounting hole 23.

[0063] Specifically, the second mounting hole 23 is used for mounting the roller brush 10. More specifically, the first mounting hole 113 and the second mounting hole 23 are aligned and locked together using fastening components. In this embodiment, bolts are used for locking, allowing the roller brush 10 to be quickly mounted on the roller 20 and preventing the roller brush 10 from detaching from the roller 20. In this embodiment, multiple first mounting holes 113 are provided, with one mounting hole located on a corresponding protrusion 13, to improve the alignment efficiency between the first mounting hole 113 and the second mounting hole 23.

[0064] In this embodiment, the first mounting hole 113 is located on one side of the roller brush portion 12 to facilitate quick and accurate confirmation of the position of the first mounting hole 113.

[0065] See Figure 2 and Figure 6 , Figure 6 This is a schematic diagram of the structure of a protective device provided in one embodiment of this utility model.

The mounting base 230 is installed on the frame 210. The end of the transmission roller 30 away from the roller 20 is installed on the mounting base 230. One end of the transmission roller 30 is connected to the driving device. The driving device is used to drive the transmission roller 30 to rotate.

[0067] Specifically, fruits and vegetables are transported within the conveyor 220. When the fruits and vegetables reach one side of the protective device 200, they are blocked. The roller brush 10 on the protective device 200 rotates, causing relative movement between the roller brush 10 and the fruits and vegetables. The fruits and vegetables move away from the roller brush 10 and are transported along the conveyor 220. The support 50 supports one end of the roller 20, and the drive roller 30 is connected to the mounting base 230, which supports the other end of the roller 20, allowing the roller 20 to be mounted on the frame 210. It should be noted that in this embodiment, the central axis of the roller 20 and the central axis of the drive roller 30 are horizontally positioned. The drive device includes a motor, and the conveyor 220 can be a conveyor belt located below the roller brush 10.
