Embodiment Construction

[0019] The present invention will be described in detail below in conjunction with the accompanying drawings and embodiments.

[0020] When the sweet potato is harvested, the present invention utilizes the material mechanics characteristics of the strong tensile force of the potato tendril, and the sweet potato harvester is driven by a tractor to work on the sweet potato ridge platform, and the potato tendril is continuously lifted along with the soil by clamping the conveying chain. When it is separated from the digging shovel group, the loose soil will fall off by its own weight, realizing the separation of potato pieces and soil, so as to complete the joint operation of potato piece harvesting and stem crushing. Sweet potato harvesting method of the present invention comprises the following steps:

[0021] (1) First, the sweet potato ridges are loosened by the suppression wheel, and the intertwined potato vines are cut off by the disc cutter (such as figure 1 shown), formi...

Abstract

The invention relates to a sweet potato harvesting method and a sweet potato harvester. The sweet potato harvesting method comprises the following steps of: (1) pressing and loosening ridges and cutting potato vines; (2) gathering the cut potato vines at the middle parts of the ridges; (3) loosening the ridges and lifting upturned soil by using a digging shovel set; (4) clamping the potato vines and continuously lifting the potato vines; (5) picking off the potatoes by using a fruit picking plate when the potato vines and the potatoes are conveyed backwards; and (6) crushing the potato vines which are continuously conveyed backwards by using a crushing roll. The sweet potato harvester comprises a frame, wherein the rear end at the bottom of the frame is provided with supporting and conveying wheels; the bottom of the frame is provided with two working sets; each working set comprises a pressing wheel, a disc cutter, an offset rotary harrow, a vibrating digging shovel set, the fruit picking plate and the crushing roll; the top of the frame is provided with a gearbox which is connected with a truck tractor; and the gearbox is in transmission connection with a clamping and conveying chain controlled by an opening and closing control wheel. The method and the harvester can greatly reduce the power consumption for separating the potatoes from soil and can be widely applied to harvesting of various potato crops.

Description

technical field [0001] The invention relates to a method for harvesting crops and a harvester thereof, in particular to a method for harvesting sweet potatoes and a harvester thereof. Background technique [0002] Sweet potato is an annual or perennial vine herb, also known as sweet potato, sweet potato, sweet potato, etc. Sweet potato cultivation in my country is dominated by ridge planting, and the main production links include soil preparation, fertilization, ridge formation, transplanting, field management, stem harvesting, and harvest transportation. The potato (potato, sweet potato) crop harvesting process mainly includes: removal of stems and leaves, digging, separation, picking up, loading and transportation. Harvesting methods of tuber crops can be divided into three types: manual harvesting, partial mechanical harvesting and mechanical harvesting, among which mechanized harvesting can be divided into segmental harvesting and combined harvesting according to the co...
