Abstract

The invention relates to a tuber type crop excavating harvester and belongs to the field of agricultural machinery. The tuber type crop excavating harvester comprises an excavating shovel, a rack and a transmission mechanism, wherein a hanging frame is arranged above the front of the rack, the excavating shovel is arranged below the front of the rack, a conveying mechanism is arranged behind the excavating shovel, the conveying mechanism is arranged below the middle part of the rack, a secondary separating mechanism is arranged behind the conveying mechanism, and the secondary separating mechanism is arranged at the rear end of the rack. According to the tuber type crop excavating harvester provided by the invention, a U-shaped cross beam is adopted for protecting a reversing gear case, so that crop stalks or weeds are prevented from tangling the reversing gear case and a power shaft in an operation process of the machine tool; and an eccentric mechanism and a planar four-link mechanism are adopted to jointly form the secondary separating mechanism, and an eccentric rotational motion is converted into a planar four-link motion to drive a shaking sieve to shake, so that clay on the surfaces of tuber type crops is reduced, and manual cleaning in a later period is convenient. The tube type crop excavating harvester provided by the invention is reasonable in the whole structure arrangement, high in operational reliability, complete in function and adaptability and is applicable to excavating harvesting operation of tuber type crops.

Description

technical field [0001] The invention relates to the field of agricultural machinery, in particular to a digging and harvesting machine for tuber crops. Background technique [0002] At present, there are tuber crop harvesting machines with various structures in the domestic market, which can basically meet the operating requirements. The main common problems are: low separation rate, high clay rate, and heavy manual cleaning workload in the later stage; The stalks of medium crops are easy to wrap around the power transmission parts of the machine, which affects the performance of the machine. Therefore, the improvement of tuber crop digging and harvesting machines has become an inevitable trend. Contents of the invention [0003] The technical problem to be solved by the present invention is to provide a tuber crop that can prevent crop stalks and weeds from being entangled in the power transmission parts of the machine tool and can effectively clean up the clay content o...
