[0029] To make the technical solution of this utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and specific embodiments.

[0030] Reference Figures 1-7A belt conveyor with variable conveying direction includes a main frame 1. The main frame 1 is equipped with a first belt conveyor unit assembly 2 and a second belt conveyor unit assembly 3 with opposite conveying directions. It should be noted that the first belt conveyor unit assembly 2 and the second belt conveyor unit assembly 3 have identical configurations and can be driven by a drive motor to convey fruit. This is an existing product. A channel 4 is provided between the first belt conveyor unit assembly 2 and the second belt conveyor unit assembly 3 for transferring fruit from the first belt conveyor unit assembly 2 to the second belt conveyor unit assembly 3, changing its conveying direction. The main frame 1 is equipped with a mounting frame 5, which is equipped with a damaged fruit sorting unit. It should be noted that the first belt conveyor unit... The camera directly above the first belt conveyor assembly 2 captures real-time images of the transported fruit. The captured images are transmitted to the image analysis module of the control system. The system uses a preset fruit damage determination algorithm to quickly compare the characteristic parameters of the fruit with those of normal fruit, accurately identify the damaged fruit, and then uses a robotic arm to grab the damaged fruit from the first belt conveyor assembly 2 and transfer it to the second belt conveyor assembly 3. This changes the transport direction of the screened damaged fruit, thus transporting the damaged fruit to another area, sorting out the damaged fruit, and collecting it in a concentrated manner by changing the transport direction. This is an existing and common-sense method, and will only be briefly explained without further elaboration. The main frame 1 is equipped with a belt cleaning mechanism 6, located below the first belt conveyor assembly 2 and the second belt conveyor assembly 3.

[0031] The belt cleaning mechanism 6 includes a connecting frame 61 fixedly connected to the main frame 1. A first roller brush 62 and a second roller brush 64 are rotatably mounted on the connecting frame 61. The first roller brush 62 and the second roller brush 64 are connected by a connecting seat 63 and are respectively located below the second belt conveyor unit assembly 3 and the first belt conveyor unit assembly 2 to clean the first belt conveyor unit assembly 2 and the second belt conveyor unit assembly 3. In addition, if it is necessary to keep the first belt conveyor unit assembly 2 and the second belt conveyor unit assembly 3 dry, they can be dried by a fan after cleaning. Since the fan has little impact on this solution, it can be installed as needed.

[0032] The belt cleaning mechanism 6 also includes a first motor 66 mounted on the main frame 1, which drives the first roller brush 62 and the second roller brush 64 to rotate.

[0033] Furthermore, a gearbox 65 is provided on the main frame 1, and a bidirectional rotation component 67 is provided inside the gearbox 65 to make the first roller brush 62 and the second roller brush 64 rotate in opposite directions.

[0034] Specifically, by driving the first roller brush 62 and the second roller brush 64 to rotate from below by the first motor 66, the juice and pulp of the damaged fruit can be promptly removed from the first belt conveyor assembly 2 and the second belt conveyor assembly 3. This prevents the fruit pulp and juice from adhering to the first belt conveyor assembly 2 and the second belt conveyor assembly 3 for a long time, thus avoiding corrosion and contamination. Furthermore, since the first belt conveyor assembly 2 and the second belt conveyor assembly 3 rotate in opposite directions, the bidirectional rotation component 67 can control the first roller brush 62 and the second roller brush 64 to rotate in opposite directions, resulting in better cleaning performance.

[0035] Furthermore, the bidirectional rotation assembly 67 includes an active rotating shaft 671 connected to the output end of a first motor 66. A first gear 673 is provided on the active rotating shaft 671. The first gear 673 meshes with a second gear 674. The second gear 674 meshes with a third gear 676. The third gear 676 meshes with a fourth gear 678. A sleeve 679 is fixedly connected to the inner side of the fourth gear 678.

[0036] The sleeve 679 is sleeved on the outside of the active rotating shaft 671. The sleeve 679 is fixedly connected to the first roller brush 62, and a first connecting shaft 672 is fixedly connected to the active rotating shaft 671. The first connecting shaft 672 is fixedly connected to the second roller brush 64.

[0037] Specifically, the first motor 66 drives the drive shaft 671 to rotate, which in turn drives the first connecting shaft 672 to rotate. The first connecting shaft 672 then drives the second roller brush 64 to rotate, and the second roller brush 64 rotates in the opposite direction to the roller shaft in the first belt conveyor unit assembly 2. Therefore, the second roller brush 64 can be used to clean the fruit pulp and juice remaining on the first belt conveyor unit assembly 2. During the rotation of the drive shaft 671, the first gear 673 is driven to rotate, which in turn drives the second gear 674 to rotate. Since the second gear 674 is also meshed with the third gear 676, the third gear 676 drives the fourth gear 678 to rotate in the opposite direction. The fourth gear 678 drives the first roller brush 62 to rotate below the second belt conveyor unit assembly 3 through the sleeve 679, thereby cleaning the fruit remaining on the second belt conveyor unit assembly 3.

[0038] Furthermore, a water supply mechanism 8 is provided below the belt cleaning mechanism 6. The water supply mechanism 8 includes a water tank 85 located directly below the first roller brush 62 and the second roller brush 64. Half of the first roller brush 62 and the second roller brush 64 are immersed in the clean water inside the water tank 85, which can wet the first roller brush 62 and the second roller brush 64. During the cleaning process, the pulp and juice attached to the brush body can be washed away in time, reducing the frequency of manual cleaning of the roller brushes and ensuring the continuous and efficient operation of the cleaning mechanism. The overall design enhances the equipment's ability to clean and maintain the conveyor belt and is adapted to the hygiene requirements of fruit transportation scenarios.

[0039] The water supply mechanism 8 also includes a lifting component for adjusting the height of the water tank 85.

[0040] Furthermore, the lifting component includes a second motor 81, and the main frame 1 is provided with a support base 7 for mounting the second motor 81.

[0041] The output end of the second motor 81 is provided with a lead screw 82, which is rotatably connected to the main frame 1 through a bearing 9. A threaded sleeve 84 for matching use is threadedly connected to the lead screw 82, and the threaded sleeve 84 is connected to the water tank 85 through a first connecting block 83.

[0042] Specifically, the rotation of the lead screw 82 is driven by the second motor 81. The rotation of the lead screw 82 causes the threaded sleeve 84 to move on the lead screw 82, which in turn drives the water tank 85 to move through the first connecting block 83. This makes it easier to lower the water tank 85 to replace the water and remove any fruit pulp that has fallen into the water tank 85.

[0043] Furthermore, the water tank 85 is equipped with a screen 88 inside, and the bottom of the screen 88 is provided with a water outlet 810 for draining the water inside the water tank 85. It should be noted that a valve can be installed on the water outlet 810 to control the start and stop of the water flow, or the water outlet 810 can be made of rubber material, which can be directly tied and sealed. Both solutions are acceptable, which can intercept the fruit pulp above the screen 88, and allow the water to drain from below.

[0044] Furthermore, the third gear 676 is rotatably mounted inside the gearbox 65 via the third connecting shaft 677, and the second gear 674 is rotatably connected inside the gearbox 65 via the second connecting shaft 675.

[0045] Furthermore, a fixing ring 89 is provided on the screen 88 to facilitate the removal of the screen 88 from the water tank 85 through the fixing ring 89.

[0046] Furthermore, a sliding rod is provided on the main frame 1, and a second connecting block 86 is provided on the outer wall of the water tank 85. The second connecting block 86 is provided with a guide groove 87 that matches the sliding rod, so that the sliding rod and the guide groove 87 can play a limiting role during the up and down movement of the water tank 85.

[0047] The embodiments described above are merely illustrative of several implementations of this utility model, and while the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of this utility model patent. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this utility model, and these all fall within the protection scope of this utility model. Therefore, the protection scope of this utility model patent should be determined by the appended claims.
