Description

Screw dish harvester

Technical field

It the utility model is related to farm equipment technical field, more particularly to a kind of screw dish harvester.

Background technology

The entitled Chinese artichoke of screw dish Chinese medicine, also known as have cutworm, Chinese artichoke, Talinum crassifolium, myrmeleontid larva grass, Chinese artichoke, township's spiral shell dish, Snail dish, scraper-trough conveyer etc., all parts of the country be distributed.The peaceful backlands area in Ningxia is especially suitable for screw dish due to weather and soil property Growth, along with the advantage of human cost, so being the main producing region that national screw colza is planted.Screw dish and young silkworm phase in a measure Seemingly, its shape is pointed at both ends, broad in the middle.The diameter of screw dish is generally 1~2 centimetre, and length is 3~6 centimetres.

In Ningxia, China, the general plantation in April of screw dish, harvesting in October.The harvesting of screw dish is similar to potato, first The cauline leaf of ground is cut off, and is then dug out the stem tuber of underground finally to be broken from root stem tuber with hand disconnected with farm implements such as spade, forks. According to the difference of soil property, the stem tuber of general sandy soil is bigger, while excavates that process is more laborsaving, and recovery process need to only carry main root Rise, stem tuber can also be brought out together, then harvests personnel and multiple stem tubers together strip get off.But if being clay soil, Excavation process is just relatively harder, while stem tuber is easier to glue with soil and sticked, and causes recovery process slower.The harvesting of screw dish Operating environment is more severe, and people is couchant in recovery process or the operation that is seated of curling up, therefore plucks personnel often after plucking one day Soreness of waist and ache in legs, while the hand of people is very dirty after harvesting, there is native adhesion in nail slot.

Screw menu plant can typically produce 20~40 stem tubers, and be centered around in umbrella around main root.0.07 hectare Having under normal circumstances probably has 10000 plant.Approximately time of 7 days could harvest and finishes 5 people of 0.07 hectare.According to current The human cost of Ningxia, China calculates, and 0.07 hectare probably needs 4000 yuan of harvesting cost.The general per mu yield 3000 of screw dish~ 4000 jin, for one jin of price steadiness at 1.5~2 yuan, per mu yield benefit is preferable.The crisp taste of screw dish, it is adapted to pickle.According to market Analysis, at 100,000 tons or so, market prospects are more wide for the domestic demand of screw dish.But because human cost is higher, limitation The development of screw dish industry.
