Oilseed rape precision direct sowing machine applicable to sticky heavy soil in hilly region

Abstract

The invention discloses an oilseed rape precision direct sowing machine applicable to sticky heavy soil in a hilly region. The oilseed rape precision direct sowing machine comprises a seed box, a direct-current driving motor, a transmission chain, a centralized seed-metering device, a seed guide tube, a herbicide spraying device, a double-disk digger, a pesticide delivery tube, a spray pump, a frame, a pesticide box, an implement supporting rod and a power device. The seed guide tube is mounted between a seed charge port of the seed-metering device and the double-disk digger, a liquid medicinebox and a herbicide sprayer are connected through a liquid medicine tube and pressed by a water pump. The oilseed rape precision direct sowing machine applicable to the sticky heavy soil in the hillyregion integrates technologies such as centralized seed-metering and closed weeding and is applicable to oilseed rape precision sowing under the condition of the sticky heavy soil in the hilly region, 6 rows of rape seeds can be synchronously sowed, large-area closed weeding can be realized, operating efficiency is effectively improved, and an implement structure is simplified.

Description

technical field [0001] The invention relates to the technical field of crop sowing equipment, in particular to a rapeseed precision direct seeding machine used in hilly areas with high moisture content and heavy soil conditions. Background technique [0002] Rapeseed, as one of the main oil crops in my country, can be generally divided into two types of rape planting areas: the first type is the spring rape area in the north, and the second type is the winter rape area in the Yangtze River Basin. Due to the advantages of geographical conditions, mechanized sowing has been gradually promoted in the northern region in recent years. However, the level of mechanized sowing of rapeseed in the Yangtze River Basin is limited by the constraints of heavy soil compaction, large slope, geographical conditions and high rainfall during the sowing season. In 2017, the mechanized sowing level of rapeseed was only 27.89%, which led to low production efficiency and high cost, which restricte...

Problems solved by technology

In 2017, the mechanized sowing level of rapeseed was only 27.89%, which led to low production efficiency and high cost, which restricted the development of rapeseed industry

Due to the complex structure of traditional planting equipment, the ground wheel is often used to drive the seed meter, which requires high power for the supporting tractor. In addition, the plots in this area are scattered and narrow, the soil is sticky and heavy, and there is a lot of rain.

As a result, it is difficult for the seeder to go down to the ground, causing the seeder to sink deeply, and it is difficult for the seeder to work normally; and the seeder is easy to slip during operation, and the degree of compaction to the soil is severe, which affects the emergence of rape seedlings

Therefore, traditional rape seeding machines are not suitable for sowing rapeseed in this area, and manual transplanting and manual sowing are used, which has high cost, high labor intensity, low efficiency, and poor seeding quality, which seriously restricts the development of rapeseed industry.

At the same time, the traditional rapeseed seeder mostly uses a single-type seed meter, which increases the weight of the transmission system and the seed meter, and the structure is relatively complicated, which is not suitable for precise seeding of rapeseed in hilly and mountainous areas.
