DESIGN AND EXPERIMENT OF KEY PART OF 2ZXS-2 CANTALOUPE TRANSPLANTER

Abstract

Aiming at the trouble of low survival rate of cantaloupe seedling in hyperthermia, drought and dry land in Turpan region of China, the existing transplanting machine is the key to mechanized and non-destructive transportation and planting of large plants of young tender melon seedlings, root water injection, and precise soil piling in planting holes，and other technical difficulties. The design of mulch film planting cantaloupe transplanter for laying pipes belts and membranes, watering and transplanting, which can complete rotary tillage, spreading drip irrigation belts, laying mulch and covering the soil around the membrane, transplanting pot seedlings on the membrane, and water injection at the bottom. This machine puts the water injection pipeline under the inner side of the transplanter, and through the multi-point linkage electric control, the seedling preservation water is injected into the bottom of the seedlings pot while the seedlings are transferred, which not only ensures the survival rate of the melon seedlings, but also an accurate piling of the planting hole is realized. The technology of transplanting with water and piled soil for planting holes effectively solved the technical problems of mechanized transplanting of cantaloupe under high temperature and arid climate conditions in Turpan. After the cantaloupe seedlings were transplanted in dry land, the probability of survival was more than 96.9% after seven point five hours of drip irrigation. Operating efficiency can reach 0.067 hectares per hour, eight times as much as manual transplanting. The speed of transplanting machine is about 1.1 m/s, the quality of transplanting rate was 93.26 percent. The operating standards of these transplanters meet the agronomic requirements for transplanting cantaloupe.
