Embodiment 1
[0053] Please refer to Figure 1 to Figure 3 , a soil scraping device for a potato harvester, comprising a rack and a soil scraping mechanism 1;
[0054] The raking mechanism 1 includes two raking wheels 11, and the 2 raking wheels 11 are symmetrically connected to both sides of the frame, and the raking wheels 11 are used for raking the soil on both sides of the ridge to the corresponding side furrow;
[0055] The raking wheel 11 includes a rotating shaft 111 and a raking blade 112;
[0056] The angle between the rotating shaft 111 and the vertical direction is 5-15 degrees, and the upper end of the rotating shaft 111 is inclined to the rear of the advancing direction of the rack;
[0057] A plurality of the raking blades 112 are distributed and connected to the rotating shaft 111 in a circular array, and the raking blades 112 include an L-shaped plate 1121 and a raking rod 1122;
[0058] The L-shaped plate 1121 includes a connecting portion 11212 for connecting the rotati...

The invention relates to the technical field of agricultural machinery, in particular to a soil digging device and method of a potato harvester, two soil digging wheels symmetrically distributed on the two sides of the front portion of a rack are designed, the included angle between a rotating shaft of each soil digging wheel and the vertical direction is 5-15 degrees, and the upper end of each rotating shaft inclines towards the rear portion of the advancing direction of the rack; and a plurality of soil digging blades are distributed on a rotating shaft of the soil digging wheel in a circumferential array. According to the design, soil on the two sides of a ridge is rotatably scrabbed to furrows on the corresponding sides by adopting a soil digging mechanism in the form of a vertical small-backward-inclined soil digging wheel, the soil digging effect is good, meanwhile, consumed power is small, the workload of digging, pushing and separating of the whole machine and corresponding resistance are greatly reduced, and the working efficiency is improved. Meanwhile, after the digging operation, soil in the middle of a ridge becomes loose and is beneficial to digging, pushing and separation, so that the operation power consumption can be greatly reduced, the potato-soil separation effect is improved, and the potato burying rate is reduced.
Description
technical field [0001] The invention relates to the technical field of agricultural machinery, in particular to a soil ploughing device for a potato harvester and a method thereof. Background technique [0002] Existing potato crop harvesters mainly use digging shovels to excavate the entire ridge and furrow and push the potato-soil mixture to the conveying and separating device to separate the soil and potato pieces. , the corresponding excavation resistance and separation resistance are also large, resulting in a large power consumption of the machine tool. When the machine is used in conjunction with small tractors (such as walking tractors) in hilly and mountainous areas, due to the heavy soil and high moisture content, problems such as excavation, push, separation resistance, unclear separation of potato soil and potato burial are common. As a result, the power consumption of machinery and tools is too large, which affects the use. As a result, many tuber crops in hill...
