Description

Technical Field

[0001] The utility model relates to the technical field of fruit cleaning, in particular to a cleaning device used for picking apples. Background Art

[0002] Fruit refers to juicy, edible fruit from plants that primarily tastes sweet and sour. Fruit is not only rich in vitamins and nutrients, but also helps digestion. Apples are rich in vitamins and nutrients, and have a sweet taste, making them popular. However, apples need to be cleaned after picking to remove surface stains, which requires the use of cleaning equipment.

[0003] Existing published patent: CN202322114821.5 A fruit picking and cleaning equipment, the soft bristles can contact the fruit to be cleaned during the forward and backward movement, and then the fruit to be cleaned can be turned over, and the outer surface of the fruit to be cleaned can be wiped at the same time. The turned fruit can contact with the sponge roller to further improve the cleaning effect. The sponge ring can contact the fruit to be cleaned by rotating forward and backward, thereby achieving all-round cleaning of the cleaned fruit.

[0004] However, in this comparative example, the apple is flipped only by the rotation of the sponge roller, resulting in a smaller flipping range of the apple. This is because the apple is generally round, and the increased water rinsing results in less friction between the apple and the sponge roller, making it easy for the apple to get stuck between the two sponge rollers during the flipping process. This will result in incomplete cleaning of the outer surface of the apple, thereby reducing the cleaning effect of the cleaning equipment on the apple and reducing the practicality of the cleaning equipment.

[0089] Among them, a plurality of silicone columns 11 are fixedly connected to the outer surface of the rubber sleeve 6 , and the silicone columns 11 are mirror-imaged with the rotating rod 5 as the center.

[0090] Furthermore, in the initial state, the mounting spring 4 is in a stretched state. When in use, it is necessary to start the first motor 12 and the second motor 16, and turn on the faucet. Water will be sprayed into the positioning frame 2 through the second fixed tube 10, the first fixed tube 9 and the water spray head 8. Then the apple is placed in the positioning frame 2. The first motor 12 starts to drive the first gear 13 to rotate, and then synchronously drives the second gear 14 to rotate. Driven by the third gear 15, all the second gears 14 rotate, and the rotation of the second gear 14 synchronously drives the rotating rod 5 to rotate, and then synchronously drives the rubber sleeve 6 and the silicone column 11 to rotate. During the rotation of the rubber sleeve 6 and the silicone column 11, the apple is driven to roll, and the rubber sleeve 6 and the silicone column 11 can also perform friction cleaning on the surface of the apple during the rotation, so that the water sprayed by the water spray head 8 can clean the apple more comprehensively, avoiding the situation where the apple is stuck between the two rubber sleeves during the flipping process, so that the apple is cleaned more comprehensively, thereby increasing the practicality of the cleaning equipment and improving the efficiency of the cleaning equipment.

[0091] Furthermore, in this solution, the rubber sleeve 6 is made of elastic rubber material, and the silicone column 11 is made of elastic silicone material, which makes the rubber sleeve 6 and the silicone column 11 elastic, which can greatly reduce the occurrence of bumps during the apple cleaning process, thereby increasing the practicality of the cleaning device;

[0092] As mentioned above, when the second motor 16 is started, the second motor 16 starts to drive the connecting rod 18 to rotate, and the rotation of the connecting rod 18 drives the two worms 19 to rotate, and then synchronously drives the worm gear 17, the positioning rod 21, the pushing slider 22, etc. to rotate. Because the installation spring 4 is initially in a stretched state, and the pushing slider 22 is elliptical, the pushing slider 22 will push the positioning frame 2 to shake up and down through the two connecting blocks 24 during the rotation process, and the pushing slider 22 shakes up and down, so that the water sprayed by the water spray head 8 can clean the apple more comprehensively, avoiding the situation where the apple is stuck between the two rubber sleeves during the turning process, so that the apple is cleaned more comprehensively, thereby increasing the practicality of the cleaning device and improving the efficiency of the cleaning device.

[0093] As mentioned above, in this solution, the distance between the rubber sleeves 6 is much smaller than the diameter of the apple.

[0094] As mentioned above, in this solution, the vibration amplitude of the positioning frame 2 is a high-frequency small-amplitude vibration to avoid the vibration amplitude causing the apples to bump, and the number of washed apples in the positioning frame 2 cannot be too large, and the washed apples cannot be piled up.

[0095] Working principle: When the device is in the initial state, the mounting spring 4 is in a stretched state. When in use, it is necessary to start the first motor 12 and the second motor 16, and turn on the faucet. Water will be sprayed into the positioning frame 2 through the second fixed tube 10, the first fixed tube 9 and the water spray head 8. Then the apple is placed in the positioning frame 2. The first motor 12 starts to drive the first gear 13 to rotate, and then synchronously drives the second gear 14 to rotate. Driven by the third gear 15, all the second gears 14 rotate, and the rotation of the second gear 14 synchronously drives the rotating rod 5 to rotate, and then synchronously drives the rubber sleeve 6 and the silicone column 11 to rotate. During the rotation of the rubber sleeve 6 and the silicone column 11, the apple is driven to roll, and the rubber sleeve 6 and the silicone column 11 can also perform friction cleaning on the surface of the apple during the rotation process, so that the water sprayed by the water spray head 8 can clean the apple more comprehensively, avoiding the situation where the apple is stuck between the two rubber sleeves during the flipping process, so that the apple is cleaned more comprehensively, thereby increasing the practicality of the cleaning equipment and improving the efficiency of the cleaning equipment.

[0096] Furthermore, in this solution, the rubber sleeve 6 is made of elastic rubber material, and the silicone column 11 is made of elastic silicone material, which makes the rubber sleeve 6 and the silicone column 11 elastic, which can greatly reduce the occurrence of bumps during the apple cleaning process, thereby increasing the practicality of the cleaning device;

[0097] As mentioned above, when the second motor 16 is started, the second motor 16 starts to drive the connecting rod 18 to rotate, and the rotation of the connecting rod 18 drives the two worms 19 to rotate, and then synchronously drives the worm wheel 17, the positioning rod 21, the pushing slider 22, etc. to rotate. Because the initial state of the installation spring 4 is in a stretched state, and the pushing slider 22 is elliptical, so during the rotation of the pushing slider 22, the positioning frame 2 will be pushed up and down through the two connecting blocks 24, and the pushing slider 22 will shake up and down, so that the water sprayed by the sprinkler head 8 can clean the apple more comprehensively, avoiding the situation where the apple is stuck between the two rubber sleeves during the flipping process, so that the apple is cleaned more comprehensively, thereby increasing the practicality of the cleaning equipment and improving the efficiency of the cleaning equipment.
