Seeding robot

Technical Field

The invention relates to the field of agricultural planting, in particular to a sowing robot.

Background

In recent years, vegetable planters have been reported in China, and the vegetable planters are only popularized in a small range due to factors such as unreliable performance and limitation of sowing conditions. At present, in rural vegetable planting, manual and simple labor tools are mainly used for both field planting and facility agricultural planting, so that the labor and the labor are wasted, the efficiency is low, the seeds are wasted, and vegetable growers are very bitter. The manual seeding mode has three kinds: namely broadcast sowing, drill sowing and hole sowing.

The existing vegetable planter has the following defects: firstly, the density of the sowed seeds is not uniform, the seeds are sparse and deficient, the seedlings are thinned and need thinning, the seeds are very troublesome to scatter, sometimes the seeds are scattered outside the ridge, the seed emergence rate is influenced, and secondly, the seeds are thinned and need thinning while overcoming some defects of the sowing, and the waste of the seeds is also caused. Scientific hole sowing, seed saving, good illumination and ventilation effects, uniform nutrition and low thinning labor intensity, but low sowing efficiency. In addition, at present, all the vegetable planting machines are large, some of the vegetable planting machines are provided with power, air is polluted during operation, the price of the whole machine is high, the movement is inconvenient, and the vegetable planting machines are difficult to apply to vegetable seeding in facility agriculture.
