Combined sieve structure of medicinal material harvester and medicinal material harvester

The invention discloses a combined sieve structure of a medicinal material harvester and the medicinal material harvester. The combined sieve structure comprises a sieve barrel with sieve meshes and asieve plate, wherein the axis of the sieve barrel is parallel to the horizontal plane, and the sieve plate is located under the sieve barrel. The combined sieve structure is characterized in that onecircle of rack is fixed on the outer wall of one end of the sieve barrel, and a bearing block is nested on the outer wall of the other end of the sieve barrel; the combined sieve structure also comprises at least one gear matched with the rack, the at least one gear is also connected with a reversing gear, a crank connecting rod is fixed on the reversing gear, the other end of the crank connecting rod is connected with one end of the sieve plate, and the other end of the sieve plate is connected with an artichoke betony harvester body. The problems that soil filtering and clearing effects arepoor and a large amount of
