Driving type corrugated disc ditching device

Abstract

The invention discloses a driving type corrugated disc ditching device which comprises a transplanter box shifting main beam and a machine frame. The device further comprises a power input part, a hydraulic drive part, a ditching assembly and a pressing and depth limiting part. The pressing and depth limiting part is arranged below the transplanter box shifting main beam, the power input part arranged on the machine frame drives the ditching assembly to work through the hydraulic drive part, and the ditching assembly comprises a plurality of ditching units. A hydraulic-drive corrugated disc is adopted for automatic ditching, the problem that ditching and soil piercing of untilled rice stubbly field are difficult can be solved, the rotation direction of the corrugated disc can be conveniently changed, the rotation direction of the corrugated disc is opposite to the machine forwarding direction in parcel of rice field with many stubbles and straw, the situations that weed is wound on a cutter head and soil is attached to the cutter head are avoided, the rotation direction of the corrugated disc should be consistent to the machine forwarding direction during work of normal parcel of rice field, and energy consumption is reduced.

Description

technical field [0001] The invention discloses a driving type corrugated disk ditching device, which is used for blanket seedlings of rapeseed or other dryland crops that need to be cut and transplanted, and relates to the technical field of hydraulically driven ditching devices. Background technique [0002] The planting mechanisms of traditional dry land transplanters mainly include clamp type (chain clamp type), seedling guide tube type, hanging basket type (duckbill type), conveyor belt type and flexible disc type, etc. Plow and plow the loose soil to open ditches or make holes for transplanting, artificially feed the seedlings, and cover the soil to suppress the solid seedlings. The ditching method is passive ditching through single disc, double disc, corrugated disc and other ditching parts, that is, the disc is buried in the soil by the weight of the machine tool, and the ditch is squeezed or pulled. There are many requirements for the weight of the machine and the n...

AI Technical Summary

Problems solved by technology

Especially in the condition of sticky and heavy soil where the rice has just been harvested, there are many rice stubbles and straws covered, and the soil is highly viscous, which greatly increases the difficulty of cutting the cutter head into the soil, and it is difficult to realize passive ditching.
