Unmanned aerial vehicle sowing device

Abstract

The invention discloses an unmanned aerial vehicle sowing device. The unmanned aerial vehicle sowing device comprises an unmanned aerial vehicle, a seed feeding assembly and a sowing assembly, whereinthe seed feeding assembly and the sowing assembly are mounted on the unmanned aerial vehicle. The seed feeding assembly comprises a seed box cover, a seed carrying box, a flow-guiding pipe and a flow-limiting baffle, wherein the top of the seed carrying box is fixedly connected with the seed box cover, the seed carrying box is fixed below a rotorcraft frame of the unmanned aerial vehicle throughthe seed box cover, the flow-guiding pipe communicates with the bottom of the seed carrying box, the electric flow-limiting baffle is arranged at the butt joint of the flow-guiding pipe and the seed carrying box, and the cross section of the flow-guiding pipe is controlled by the flow-limiting baffle to adjust the seed feeding flow of the seed carrying box. The sowing assembly comprises a sowing mounting plate and a sowing plate driven by a sowing motor, wherein the sowing mounting plate is fixed to rod pieces of a support frame of the unmanned aerial vehicle through detachable pipe clamps, the sowing motor is fixed to the sowing mounting plate and is in transmission connection with the sowing plate which is rotationally arranged relative to the sowing mounting plate, and the flow-guidingpipe of the seed feeding assembly is positioned above the sowing plate. The unmanned aerial vehicle sowing device has a reasonable structure, can adjust sowing effects of different seeds correspondingly, and ensures optimization of the sowing effects.

Description

technical field [0001] The invention belongs to agricultural seeding equipment, in particular to an unmanned aerial vehicle sowing device. Background technique [0002] The development of agricultural mechanization is a necessary condition for the development of modern agriculture. Seed sowing is a relatively difficult technology, because the sowing density is difficult to control. If the sowing density is too high, it will lead to poor individual development and easy lodging; if the sowing density is too low, it will lead to severe yield reduction. At present, sowing is mainly divided into manpower sowing and mechanical sowing. Manpower sowing is not only labor-intensive and long working hours, but also requires certain experience to control the sowing density. Novices are prone to uneven sowing. Mechanical sowing is mainly divided into manual hand-held machinery and land machinery. Hand-held machinery needs to be carried manually to plant seeds, which is labor-intensive a...

Problems solved by technology

Seed sowing is a relatively difficult technology, because the sowing density is difficult to control. If the sowing density is too high, it will lead to poor individual development and easy lodging; if the sowing density is too low, it will lead to severe yield reduction

At present, sowing is mainly divided into manpower sowing and mechanical sowing. Manpower sowing is not only labor-intensive and long working hours, but also needs certain experience to control the sowing density. Novices are likely to cause uneven sowing.

Mechanical sowing is mainly divided into manual hand-held machinery and land machinery. Hand-held machinery needs to be carried manually to plant seeds, which is labor-intensive and inefficient. Land machinery is suitable for large-scale sowing and has high efficiency, but it is difficult to go to the ground. Strict terrain requirements for sowing, heavy weight, easy to cause damage to the land and other shortcomings

[0003] With the advancement of science and technology, emerging unmanned aerial vehicles have begun to be applied to agricultural mechanization. High-power unmanned aerial vehicles have the characteristics of simple structure, small size, light weight, heavy load, and simple operation. They are widely used, such as application The Chinese patent No. 201410455577.1 discloses a precision seeding operation system and method based on an unmanned aerial vehicle platform, using a single-rotor UAV as a platform for wind field sowing; the Chinese patent application No. 201521123128.3 discloses a drone The human sowing and fertilizing device is designed for the sowing structure carried by the drone, but when the seeding opening is small, the effect of seed leakage is not good, and at the same time, the position of the seeding opening relative to the spreading disc is fixed, so that the seeds fall on the spreading disc The position is immutable, and the position where the seeds fall on the disc has a great influence on the final sowing effect, which will cause the distribution of the sown seeds to be basically fixed, and the parameter adjustability is not high
