Description

Technical Field

[0001] The utility model relates to a multi-stage conveying device with a seedling rowing function for potato harvesting, belonging to the technical field of agricultural product harvesting. Background Art

[0002] Potatoes, also known as potatoes, yam eggs, ground eggs, sweet potatoes, Dutch potatoes, etc., are annual herbaceous plants of the Solanaceae family. The aboveground stems of potatoes are diamond-shaped and hairy. The leaves are simple when they are first born, and gradually grow into odd and unequal pinnate compound leaves, which are ovate to oblong in shape. With the advancement of technology, agricultural machinery is often used for sowing and harvesting of agricultural products.

[0003] For example, a desludging conveying device for a potato harvester with patent number CN202220137028.X is composed of a frame, a driving wheel, a desludging sprocket, a lifting belt, a collecting chute, a lifting sprocket, a lifting roller, a desludging conveying rod, and a packaging bin. Two chains connect two driving wheels to form a chain transmission system. A desludging conveying rod is connected at a certain distance between the two chains, which is called a desludging mechanism. Two lifting rollers are connected by a lifting belt to form a lifting mechanism.

[0004] Since the above-mentioned conveying device is used to convey and collect potatoes after harvest, but the stalks of potatoes are killed before or after the potato harvest, the stalks will be collected in the subsequent potato harvesting process, which affects the collection of impurities such as the stalks in the potatoes and makes it difficult to clean them, which has a certain adverse effect on actual use, and therefore needs to be improved.

The first conveyor belt 5 can be used to collect potatoes. The crushed stalks and potatoes are transported upward, and the guide rollers 8 of the screening frame 6 at a high position are driven to screen potatoes and crushed stalks. Because the potato is much larger than the crushed stalk, the crushed stalk can be dropped through the gap between the adjacent guide rollers 8. If the crushed stalk does not fall and abuts between the two guide rollers 8, the electric telescopic rod 9 can be operated to drive the lifting plate 10 to move. The dredging head 12 above the lifting plate 10 moves upward to push the crushed stalks that have not fallen down and drop them. Under the action of the spring telescopic rod 11, it moves elastically, and the crushed stalks can be concentrated through the focusing plate 20. Under the collective guidance, the movement trajectory of the lifting plate 10 is limited by the setting of the balance plate 21 and the balance groove 22, which reduces the tilting of the lifting plate 10 during the movement. The rotation of the rotating wheel rod 13 can drive the pulling hook 14 to rotate, and the stalks gathered on the left side of the inner wall of the screening frame 6 can be pushed to the right side, reducing the tilting and accumulation of the broken stalks.
