Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0022] Reference Figure 1-5 The present invention provides an adjustable spacing blueberry sorting conveyor belt, including a fixed frame 1, a slide rail 2 fixedly connected to the top of the fixed frame 1, the number of slide rails 2 is two, the interior of each slide rail 2 is provided with a slide groove 3, the interior of the two slide grooves 3 is slidably connected with a first slider 4 and a second slider 11 in a front-to-back sequence, the first slider 4 and the second slider 11 are rotatably connected with a connecting shaft 5, the number of connecting shafts 5 is three, the exterior of each of the three connecting shafts 5 is fixedly connected with a roller 6, and the exterior of the three rollers 6 is fitted with a conveyor belt 19;

[0023] A transmission assembly 10 is movably connected between the connecting shaft 5 in the middle and the connecting shafts 5 at both ends. Two sets of transmission assemblies 10 are provided. The output end of the motor 8 is fixedly connected to the end of the connecting shaft 5 on the outer side away from the second slider 11. A first threaded hole 12 is provided on the top of the slide rail 2. A first limiting screw 13 is threaded into the first threaded hole 12, and the bottom of the first limiting screw 13 is in contact with the top of the first slider 4. In use, rotating the first limiting screw 13 releases the restriction on the first slider 4 and the second slider 11, thereby synchronously adjusting the distance between multiple sets of first sliders 4 from both sides of the slide rail 2, thus achieving the adjustment of the spacing of this utility model. After adjustment, rotating the first limiting screw 13 again limits the first sliders 4 and the second slider 11 on both sides, thus facilitating the adjustment of the spacing of this utility model. Furthermore, the three rollers 6 form a group, and the interval between each group of rollers 6 can be adjusted according to the size of the blueberries.

[0024] The transmission assembly 10 includes a first transmission wheel 1001 and a second transmission wheel 1002. A transmission belt 1003 is movably connected between the first transmission wheel 1001 and the second transmission wheel 1002. The second transmission wheels 1002 inside both sets of transmission assemblies 10 are mounted on the connecting shaft 5 located in the middle. In use, the motor 8 is started, which drives the connecting shaft 5 located on the outer side to rotate. This causes the three connecting shafts 5 to rotate synchronously through the two sets of transmission assemblies 10, so that the three rollers 6 rotate synchronously, and the blueberries are transported by the conveyor belt 19.

[0025] Both the first slider 4 and the second slider 11 are provided with limiting blocks 9 at their bottoms, and the limiting blocks 9 are in contact with the inner wall of the slide groove 3.
