Abstract

The invention relates to an air suction type precision pseudo-ginseng seed sowing device and belongs to the technical field of agricultural machinery. A chain wheel is connected with a right end cover through a fixed bolt; a hollow shaft is mounted on an end cover of a roller through a bearing I; a draught fan is communicated with one end of the hollow shaft; a chain wheel is mounted on the outer side of the right end cover of the roller and the chain wheel is connected with the hollow shaft through the bearing I; a friction roll is arranged at the bottom of the roller and is in interference fit with the inner wall of the roller; the friction roll is equipped with a bearing II and a bearing sleeve sleeves an outer ring of the bearing II; a forward and backward rotary adjusting mechanism is mounted between the bearing sleeve and the hollow shaft through a mounting hole II and the bottom of the forward and backward rotary adjusting mechanism is connected with the bearing sleeve; seed suction holes are formed in the roller; the bearing I is fixed by a clamp spring fixed bearing outer ring and a shaft shoulder fixed bearing inner ring of the hollow shaft; the bearing I is sealed by a framework oil seal; a left end cover and the right end cover are fixedly connected with the roller; and the diameters of the seed suction holes are smaller than those of seeds. The air suction type precision pseudo-ginseng seed sowing device has low use cost and is easy to operate; and damage to the seeds is not caused so that the survival rate of the seeds is high.

Description

technical field [0001] The invention relates to an air suction type Panax notoginseng precision seed metering device, which belongs to the technical field of agricultural machinery. Background technique [0002] Wenshan, Yunnan is the origin and production area of ​​the precious medicinal material Panax notoginseng. It has gone through a long time from wild to home-grown. In the 21st century, the production of Panax notoginseng has developed rapidly and has formed a large-scale and industrialized development pattern. However, in the In the process of cultivation technology, it is still in the manual stage of farming, and there is basically no application of agricultural machinery. During the planting and harvesting seasons, due to the short time, heavy workload, and the fact that no one is welcome during the season, a lot of labor must be used to complete the planting and harvesting work. The Panax notoginseng planting season is from late November to mid-January of the foll...
