a seeder

Abstract

The invention discloses a seeder and relates to the field of agricultural machinery. The seeder comprises a vehicle body, a transmission component and a seeding component, wherein the transmission component and the seeding component are arranged on the vehicle body; and the seeding component is provided with a soil turning component, an earthing shovel and an adjusting component. The seeder allowstwo rows to be planted at the same time, and allows the sowing spacing and the row spacing to be adjusted; when the sowing row spacing is adjusted, the ditching depth is automatically adjusted; moreover, fertilization can be carried out while seeding is realized, so that the labor amount of workers is reduced; in addition, the utilization rate of fertilizer is increased, and waste is avoided; thetransmission component allows a seeding turntable to rotate through the movement of the vehicle body, no additional driving devices are required, and cost is reduced; the vehicle body can be driven to move through an external driving device, and the problem can be solved that the driving device for driving the seeding turntable is damaged, so that seeding cannot be carried out, and time is wasted.

Description

technical field [0001] The invention relates to the field of agricultural machinery, in particular to a seeder. Background technique [0002] The seeder is an indispensable agricultural machinery in agricultural production. For the planting of some crops, it is necessary to sow a single seed on demand. One is that the quantitative sowing is easy to grow, and the other is to save crop resources. [0003] Most of the existing seeders use drills, which are divided into wide row drills and narrow row drills. Wide row drills are suitable for crops that have a large area per plant and require intertillage, such as corn and soybeans, and narrow row drills are suitable for rice. , flax, etc. The sowing depth of each crop is different. For example, the suitable sowing depth of corn and soybean is 3-5cm, and the sowing depth of rice and flax is 1-1.5cm. According to different crops to adjust the ditching shovel, the sowing efficiency is low, and the distance between the rows of the m...

Problems solved by technology

[0003] Most of the existing seeders use drills, which are divided into wide row drills and narrow row drills. Wide row drills are suitable for crops with a large area per plant that require intertillage, such as corn and soybeans, and narrow row drills are suitable for rice. , flax, etc. The sowing depth of each crop is different. For example, the suitable sowing depth of corn and soybean is 3-5cm, and the sowing depth of rice and flax is 1-1.5cm. According to different crops to adjust the trenching shovel, the sowing efficiency is low, and the distance between the rows of the multi-row seeding machine cannot be adjusted, and it drives the rotation of the sowing turntable through a separate drive device, and through Adjusting the rotating speed to realize the adjustment of the spacing between seeds, on the one hand, setting the driving device alone will increase the production cost, on the other hand, if the driving mechanism is damaged, it will be impossible to sow seeds, which wastes time. At the same time, the existing seeders can only sow seeds. After sowing, manual fertilization is required, which increases the workload of workers on the one hand, and on the other hand, when workers fertilize, they usually sprinkle the fertilizer directly into the field, and the fertilizer cannot be fully absorbed, resulting in a low utilization rate of the fertilizer.
