[0002] Fruit refers to juicy, sweet and sour, edible plant fruits. Fruits are not only rich in vitamins and nutrients, but also can promote digestion. During the picking process, fruits carry many impurities such as leaves, insects, straws and dust, which need to be screened, which requires the use of fruit screening machines.

[0003] The utility model patent is named "A drum-type fruit screening device" (application number 202321857979.5) and proposes "This utility model discloses a drum-type fruit screening device, including a bracket and a U-shaped frame, a hopper is welded to one side of the upper part of the bracket, and a support is arranged below the upper hopper; in this utility model, by starting the reduction motor, the output end of the reduction motor drives the screening drum inside the U-shaped frame under the action of the pulley, the transmission belt and the end shaft, so that the discharge port of the screening drum reciprocates with the through port of the second baffle. The opening of the screening cylinder is reciprocatingly connected to the material nozzle of the upper hopper. At this time, by putting the blueberries to be screened into the upper hopper, the blueberries are forced to pass through the opening into the screening cylinder under the action of gravity, and the impurities carried by them are screened out by the filter net of the screening cylinder, so that the blueberries intermittently fall into the collection box from the discharge port and the through port, so as to achieve efficient screening of blueberries. Compared with the traditional screening device, it does not need to stop loading and unloading, and has the advantage of continuous screening.

The material enters the screening component 2 through the feed port 1 for screening and impurity removal, and then enters the storage box 4 through the discharge port 3 for storage, and the impurities fall on the U-shaped frame 5. This process is usually equipped with a spray pipe or other water spray for cleaning to achieve a better cleaning effect; it is worth noting that when the impurities and clean water fall on the U-shaped frame 5, most of the impurities and clean water are discharged into the waste collection box 6 along the guide plate 19 and the baffle plate 7 under the action of their own gravity. , the remaining impurities and clean water adhere to the U-shaped frame 5. When cleaning is needed, the first motor 9 is started first. The power output end of the first motor 9 drives the bidirectional screw 10 to rotate to make the slider 11 move back and forth in the slide groove 8, so the scraper 12 moves back and forth to push the remaining impurities and clean water into the waste collection box 6; when the impurities and clean water in the waste collection box 6 need to be discharged, the valve 16 is first opened, and the second motor 17 is started. The power output end of the second motor 17 drives the auger 18 to rotate, and the auger 18 runs to discharge the impurities and clean water through the discharge pipe 14 and finally discharged from the discharge port 15.

[0029] Preferably, a sealing rubber ring is installed at the contact point between the waste collection box 6 and the discharge pipe 14. Such a structural design makes the equipment more sealed and prevents the cleaning liquid from leaking out.

[0030] Preferably, a sealing rubber ring is installed at the contact point between the discharge pipe 14 and the discharge port 15. Such a structural design makes the equipment more sealed and prevents the cleaning liquid from leaking out.

[0031] Preferably, a rubber cushion is installed on the chute 8. Such a structural design reduces the friction damage to the chute 8 and prolongs the service life of the equipment.
