Multifunctional direct seed sowing machine for coating grass on rape

Abstract

The invention discloses a multifunctional direct seed sowing machine for coating grass on rape. The multifunctional direct seed sowing machine comprises a walking system, a vehicle frame, a towing bracket, a sowing and fertilizing system, and a rotary tillage ditching system, wherein the vehicle frame is arranged on the walking system; the towing bracket is connected with the vehicle frame and arranged behind the walking system; a horizontal header, a straw chopping and conveying system and a throwing about mechanism, which are connected with each other in sequence, are arranged on the vehicle frame from front to back; the rotary tillage ditching system is arranged on the towing bracket below the throwing about mechanism; the sowing and fertilizing system is arranged on the vehicle frame; and the sowing ports and the fertilizing ports of the sowing and fertilizing system are arranged before and behind shallow winter breaking and ditching formed ridges respectively. According to the multifunctional direct seed sowing machine, six processes such as shallow ploughing, stubble cleaning, sowing, fertilizing, ridge forming ditching, and grass coating between sowed rows can be fulfilled simultaneously, so as to effectively solve the problems of complex processes, low efficiency, and grass winding and mud hilling on soil operation components, greatly improve the working performance, efficiently realize soil moisture conservation and heat insulation on rape ridges due to secondary utilization of former plant stubble, and improve the operation quality of sowing.

Description

technical field [0001] The invention relates to a seeding machine, in particular to a multi-functional rapeseed grass-covered direct-seeding seeder capable of chopping previous crops and returning them to the field. Background technique [0002] At present, the self-sufficiency rate of edible oil in my country is less than 40%, and it is necessary to vigorously develop the cultivation of oil crops to solve the national oil supply security crisis. Taking winter rapeseed as an example, the Yangtze River Basin is the main production area of ​​winter rapeseed, with an annual planting area of ​​120 million mu, and there are still nearly 80 million mu available for planting rapeseed. Traditional manual labor cannot meet the large-scale production requirements of rapeseed, and the existing planting area The level of mechanization is quite low. To increase the total output of rapeseed, we must vigorously develop the mechanization of rapeseed production. [0003] Due to its unique e...

Problems solved by technology

Taking winter rapeseed as an example, the Yangtze River Basin is the main production area of ​​winter rapeseed, with an annual planting area of ​​120 million mu, and there are still nearly 80 million mu available for planting rapeseed. Traditional manual labor cannot meet the large-scale production requirements of rapeseed, and the existing planting area The level of mechanization is quite low. To increase the total output of rapeseed, we must vigorously develop the mechanization of rapeseed production

[0003] Due to its unique environmental characteristics, the Yangtze River Basin mainly implements the "rice-rice-oil" production model, which causes seasonal conflicts between rapeseed and rice. When winter rapeseed is planted, there are often stubbles left after harvesting rice, and the height Generally, it is about 40-50cm, and there are many weeds. The existing rape seeder mainly uses the rotary tillage device to plow and bury the stubble left in the field. Due to the high stubble left after harvesting rice in the southern paddy field, the soil is heavy and hardened. It is easy to entangle rotary tiller shafts, plows and other working tools. Turning the soil before sowing will greatly affect the normal operation of the planter due to grass and mud entanglement on the tillage parts, and the effect of returning straw to the field is not good; if it is directly burned, it will cause environmental pollution. Pollution is not conducive to environmental protection. At the same time, rice straw is rich in cellulose, and also contains potassium, calcium, phosphorus and other chemical elements. It is the main source of organic matter in the soil. Natural rotting in the field can not only fertilize the field and improve soil quality It can also increase the yield of the next crop, but the complete straw decay process is relatively long, and it cannot effectively affect the growth cycle of rapeseed
