Vibratory digging harvester for winter potato

Abstract

The invention relates to a vibratory digging harvester for winter potato, comprising a frame, a gearbox, a vibratory digging device, a two-stage conveyer and a separation mechanism, with the gearbox,the vibratory digging device, the two-stage conveyer and the separation mechanism mounted on the frame. The gearbox powers the vibratory digging device, the two-stage conveyer and the separation mechanism. The vibratory digging device comprises a vibratory digging blade to dig crops. The two-stage conveyer comprises a conveying chain screen to convey and primarily screen silt. The separation mechanism comprises a vibratory flow-combing slide mesh to screen silt, the front end of the conveying chain screen is positioned at the rear of the digging blade, and the rear end of the conveying chain screen is positioned above the front end of the vibratory flow-combing slide mesh. The vibratory digging harvester for winter potato is simple in structure and convenient to operate, has adjustable positions and adjustable vibrational amplitude, digging depth and penetrating angle, may arrive at optimal digging as practice requires so as to achieve reduced digging drag, increased potato exposure rate and reduced damage rate, has a promising market in the harvest of potato and other tubers, and is a harvesting machine for potato and other tuberous crops.

Description

technical field [0001] The invention relates to a harvesting machine for tuber crops such as potatoes, in particular to a vibration digging and harvesting machine for winter potatoes. Background technique [0002] At present, in the field of winter potato harvesting in southern my country, most farmers mainly harvest manually in order to reduce the rate of potato damage, which is labor-intensive, takes a long time to harvest, and requires high labor costs. The existing small potato harvesters on the market mainly use fixed mechanical harvesting, but it is easy to cause potato soil adhesion during harvesting, the potato yield is low, and it is difficult to dig potatoes manually; there are also some small vibrating potato harvesters that use fixed amplitude and Excavation depth, the same excavation method is adopted for excavation in different soil conditions, which is prone to problems such as large excavation resistance, easy blockage, and high potato damage rate.

[0002] At present, in the field of winter potato harvesting in southern my country, most farmers mainly harvest manually in order to reduce the rate of potato damage, which is labor-intensive, takes a long time to harvest, and requires high labor costs.

The existing small potato harvesters on the market mainly use fixed mechanical harvesting, but it is easy to cause sticking of potato soil during harvesting, the rate of potato production is low, and it is difficult to dig potatoes manually; there are also some small vibrating potato harvesters that use fixed amplitude and Excavation depth, the same excavation method is adopted for excavation in different soil conditions, which is prone to problems such as large excavation resistance, easy blockage, and high potato damage rate
