Description

Technical Field

[0001] The utility model relates to the technical field of screening mechanisms, in particular to a harvesting device with a screening mechanism. Background Art

[0002] Rice, commonly known as rice, is an annual aquatic herb of the Poaceae family. When harvesting rice, a corresponding harvester with screening function is needed to harvest and screen it.

[0003] At present, in the prior art, a Chinese patent with a publication number of CN219698486U discloses a harvesting device for rice planting, wherein a second motor is arranged on one side of a support frame, and a first connecting rod is rotatably connected to the output end of the second motor, and one end of the first connecting rod is rotatably connected to the second connecting rod, so that when the second motor is started, the support frame is driven to move back and forth under the restriction of a limiting bottom bar, so as to avoid excessive concentration of rice grains and inconvenience in collection, and to avoid clogging of the sieve holes during the screening process. However, in actual use, the device cannot effectively prevent the clogging of the sieve holes during the screening process only by the reciprocating motion of the drag frame, and the sieve holes may still be blocked by large grains of rice. In view of this, we propose a harvesting device with a screening mechanism. Utility Model Content
