Soil-cutting excavation-type potato harvesting machine

Abstract

The invention discloses a soil-cutting excavation-type potato harvesting machine. The soil-cutting excavation-type potato harvesting machine includes a cutting device, an excavation device, a conveying device, a walking device, a three-point hanging device, a transmission device and a rack. The cutting device is composed of a first cutter shaft, a first cutter rest, a third soil cutting circular disc and the like. The excavation device is composed of a first excavation shovel, a second excavation shovel, a third excavation shovel, a fourth excavation shovel and a fifth excavation shovel; the conveying device is composed of a conveying chain and baffle plates. The walking device is composed of wheels and wheel shafts. The three-point hanging device is composed of an upper suspension, a first lower suspension, a second lower suspension and a rear support frame. The power transmission device is composed of a decelerator, a first belt, a first cutter shaft drive belt wheel, a second belt wheel, a fourth belt and the like. All soil cutting circular discs are mounted on the forefront of the whole machine, all the excavation shovels are mounted behind the soil cutting circular discs, during operation, the soil cutting circular discs enter and cut soil, and then the excavation shovels conduct secondary excavation on the cut soil. By adopting the soil-cutting excavation-type potato harvesting machine, the problems are solved that by adopting a single excavation shovel, excavation operation resistance is large and the excavation effect is poor; therefore, soil breaking and harvestingoperation can be better conducted.

Description

technical field [0001] The invention relates to a soil cutting digging type potato harvester, which belongs to the field of agricultural machinery equipment. Background technique [0002] The potato staple food strategy has rapidly expanded the potato planting area. It is very necessary to mechanize the whole process of potato planting and harvesting. Most of the current potato harvesters use fixed digging shovels for digging. The digging resistance is very large, the digging effect is poor, and it is easy to deform the digging shovel. , reduce the excavation efficiency, and a single fixed digging shovel needs a large-horsepower tractor for traction to harvest potatoes, which consumes a lot of energy, and small plots in hilly and mountainous areas are small, making it difficult for large tractors to enter, resulting in shortcomings in potato harvesting in hilly and mountainous areas, which affects the industry Healthy and rapid development, so it is necessary to develop a me...

[0002] The potato staple food strategy has rapidly expanded the potato planting area. It is very necessary to mechanize the whole process of potato planting and harvesting. Most of the current potato harvesters use fixed digging shovels for digging. The digging resistance is very large, the digging effect is poor, and it is easy to deform the digging shovel. , reduce the excavation efficiency, and a single fixed digging shovel needs a large-horsepower tractor for traction to harvest potatoes, which consumes a lot of energy, and small plots in hilly and mountainous areas are small, making it difficult for large tractors to enter, resulting in shortcomings in potato harvesting in hilly and mountainous areas, which affects the industry Healthy and rapid development, so it is necessary to develop a method that can reduce the excavation resistance, change the traditional single fixed shovel excavation method to the excavation method after cutting the soil, improve the excavation quality, speed up the excavation speed, and reduce the supporting power demand for excavation
