A fully hydraulic crawler type unmanned rape seeding machine

Abstract

The invention discloses a full hydraulic crawler-type unmanned rapeseed direct sowing machine, and relates to the technical field of agricultural equipment. The full hydraulic crawler-type unmanned rapeseed direct sowing machine comprises a chassis, a hydraulic device, a sowing device and a control device. According to the direct sowing machine, the chassis is a rubber crawler chassis and driven by a hydraulic motor. A hydraulic oil tank is carried on the chassis, the hydraulic device and the control device are fixed onto the oil tank, and the sowing device is mounted at the tail of a body. The direct sowing machine takes hydraulic pressure as power, so that walking and steering of the chassis and rising and falling of the sowing device are achieved. An unmanned control system is built bya software control system, an electric control hydraulic valve set, a satellite positioning receiver, a vision sensor, an electronic compass, a photoelectric sensor, a data acquisition card and a signal processing module, geographic information of a land and position information of the direct sowing machine are automatically acquired, paths are automatically planned and tracked, field turning andobstacle avoidance are automatically implemented, the sowing device automatically rises and falls, seeds are automatically discharged along with the speed of the direct sowing machine and the like. Bythe aid of module design, the direct sowing machine is compact in structure, portable, flexible, good in field passing ability and easily and automatically controlled.

Description

technical field [0001] The invention relates to the technical field of agricultural equipment, in particular to a fully hydraulic crawler-type unmanned rape direct seeding machine. Background technique [0002] China's rapeseed planting area ranks among the top in the world, with about 100 million mu planted per year. Among them, winter rapeseed accounts for more than 85%, and the middle and lower reaches of the Yangtze River are the main production areas of winter rapeseed in my country. In the middle and lower reaches of the Yangtze River, the previous crop of winter rapeseed is mostly rice, and the soil is compacted and heavy. However, traditional rapeseed planting machinery is generally heavy, and the field is prone to slipping and subsidence. In addition, factors such as small and scattered fields severely limit the operation. Efficiency, resulting in a low level of mechanized sowing of rapeseed. Traditional rape seeding machines cannot meet the requirements of rape s...

Problems solved by technology

In the middle and lower reaches of the Yangtze River, the previous crop of winter rapeseed is mostly rice, and the soil is compacted and heavy. However, traditional rapeseed planting machinery is generally heavy, and the field is prone to slipping and subsidence. In addition, factors such as small and scattered fields severely limit the operation. Efficiency, leading to low level of mechanized seeding of rapeseed

Traditional rape seeding machines cannot meet the requirements of rape seeding in this area. With the innovation and development of agricultural technology, small and light rape seeding machines with good field passability have appeared, but such seeders usually need to be walked under the control of the driver. As well as the operation process, it is not only difficult to continue to operate for a long time, but also the seeding effect depends to a large extent on the driver's experience, which is difficult to guarantee

This production mode will consume a lot of labor costs, and it is very unfavorable for the intelligent and industrialized development of rapeseed under the current situation of shortage of rural labor force
