Description

Technical Field

[0001] The invention belongs to the technical field of harvesters, and in particular relates to a radish harvester. Background Art

[0002] Radish is a common root vegetable, and its edible rhizome is buried in the soil. You need to grab the top of the radish leaves by hand to pull the radish out of the soil, and then cut off the radish leaves. This method of harvesting is more laborious when planted in large quantities, and it is easy to fall down when pulling out the radish because the soil is hard.

[0003] A Chinese patent with authorization announcement number CN215011649U discloses a radish harvester, comprising a body, a conveying frame, a radish positioning device, a parallel conveyor belt, a splitting blade and a chopping blade; the conveying frame is fixed to the body; the conveying frame comprises an inclined frame; the radish positioning device is installed at the lower end of the inclined frame, close to the ground, and can gather the radish leaves to be harvested in the field; the parallel conveyor belt is installed in the inclined frame following the movement of the inclined frame, can clamp the gathered radish leaves, and pull the radish out of the ground and convey it to the higher end of the inclined frame; the splitting blade is installed under the inclined frame, located between the roots and leaves of the radish conveyed by the parallel conveyor belt; the chopping blade is installed below the top of the inclined frame, and the radish leaves cut by the splitting blade fall into the chopping blade.

[0004] Although this type of radish harvester can meet the needs of some scenarios, the fields in some mountainous and hilly areas are located on hillsides and mountain tops, and it is difficult for large machines to reach the fields through narrow mountain roads.
