An anti-blocking device for wheat no-tillage seeder with opposite spiral straw returning

Abstract

The invention belongs to the field of agricultural machinery, and particularly relates to an anti-blocking device for a wheat no-tillage seeder with opposing spiral straws. A rotary tiller (4), a drive Mechanism, opposing spiral straw feeding mechanism (1), straw returning anti-blocking mechanism (2) and ditch opener (3); opposing spiral straw feeding mechanism (1) includes blade shaft (603), opposing A double-helical blade group (301), a frame (302), a bearing (303) and a support seat (304); the straw returning anti-blocking mechanism (2) includes n straw returning anti-blocking units (401) , said n≥1; the device can effectively reduce the blockage of the seeder and the opener, improve the operation stability and the consistency of the ditch depth; it can effectively clean the straw on the sowing belt, and realize the orderly return of the straw in the field, which can Reduce the seed drying rate, improve the quality of no-tillage sowing, and help increase crop production.

Description

technical field [0001] The invention belongs to the field of agricultural machinery, and in particular relates to an anti-blocking device for wheat no-tillage planters with opposed spiral straws. Background technique [0002] Conservation tillage is a farming mode that implements no-tillage and less-tillage on the uncultivated land covered with the straw of previous crops. This farming method can increase the content of soil organic matter, effectively reduce soil wind erosion and water erosion, and improve soil fertility and drought resistance. . The planting mode of no-tillage operation in the drip irrigation area adopts the arrangement of wide and narrow rows, and the field has good ventilation and light transmission. Combining the protective tillage technology with the wide and narrow row planting mode in the drip irrigation area can save costs and increase efficiency. effect. During the no-tillage planting operation in the wide and narrow rows of the Bole drip irrigat...

AI Technical Summary

Problems solved by technology

During the no-tillage planting operation in the wide and narrow rows of the Bole drip irrigation area in Xinjiang, due to the dryness and wind, the amount of straw on the surface is large and hard, and the distribution is disorderly. On the one hand, the no-tillage planter consumes a lot of power and often blocks. On the other hand, if the planter spills straw and stubble into the sowing row during operation, it will affect the contact effect between the seeds and the soil, reduce the quality of seed implantation, and increase the difficulty of effective sowing

Therefore, in order to solve the problem that the no-tillage seeder is easy to be blocked and the messy straws are returned in an orderly manner, a device that can discharge the straws from the seeder in time, gather them in an orderly manner to the non-sowing area and effectively Anti-blocking return device to improve the cleanliness of the seed belt
