Male parent cutting machine for hybrid rape seed production field

Abstract

The invention discloses a male parent cutting machine for a hybrid rape seed production field. The male parent cutting machine comprises a rack which is provided with a handle, an engine, a gear shifting handle, a walking gearbox, a spiral conveying roller gearbox, two cutter gearboxes, two reel mechanisms and two dividing plate assemblies. A first output shaft on the engine is in transmission connection with an input shaft of the walking gearbox through a first transmission mechanism, an input shaft of the cutter gearbox is in transmission connection with an input shaft of the walking gearbox through a second transmission mechanism, and the reel mechanism is in transmission connection with an output shaft of the cutter gearbox. A second output shaft on the engine is in transmission connection with an input shaft of the spiral conveying roller gearbox through a power output transmission box, a pair of spiral conveying rollers is arranged on an output shaft of the spiral conveying roller gearbox, and a double-layer cutting knife is arranged on an output shaft of the cutting knife gearbox. According to the cutting machine, the cutting efficiency and effect of the rape male parents are greatly improved, time and labor are saved, and the labor cost is reduced.

Description

technical field [0001] The invention relates to the technical field of agricultural machinery, and more specifically relates to a male parent cutting machine for hybrid rapeseed farming. Background technique [0002] Rapeseed is the most important oil crop with the largest planting area in my country. With the advancement of science, the use of rapeseed is not only satisfied with food, but also extended to other fields such as feed, fertilizer, industry, medicine, etc. Requirements, high oil content, strong resistance, good new varieties suitable for mechanical operations are needed, and their planting area is also expanding. The seed production link in the production of rapeseed hybrids is particularly important in the process of popularizing rapeseed varieties. [0003] At present, fine varieties of rapeseed are generally hybrids, and their seed production generally uses lines with stable agronomic characteristics, excellent economic characteristics, and qualified quality ...

AI Technical Summary

Problems solved by technology

In order to ensure the seed purity of rapeseed hybrid seed production, all hybrid plants must be uprooted when the father / female parent is removed; after the male parent completes the pollination task, the male parent must also be cut off (cut off), and then held outside the seed production field for concentration, and Transport away from the farming field for destruction; if the miscellaneous plants and male parents are not removed in time, not only will they compete for the water and fertilizer of the remaining plant, but also the purity of the seeds will be affected due to the mixing of the male parents

In the actual operation, the male parent can be cut off manually in the experimental field with a small area, and the field seed production area of ​​the new rapeseed variety is as small as tens of mu, generally hundreds of mu, and sometimes thousands of mu when the area is large. The workload is very large, it takes a lot of manpower, material and financial resources, and the effect is relatively poor
