Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of seeding devices, and more specifically to an unmanned aerial vehicle seeding device. Background Art
[0002] Drone rice direct seeding is a new rice cultivation technology that uses a machine to accurately locate the field and then directly direct seeding. Compared with the traditional sowing method, it directly eliminates the two links of raising and transplanting rice seedlings. The sowing uniformity is better than manual sowing, and the production efficiency is also higher. It is of great significance to realize the lightweight, professional and large-scale rice production. Gao'an was the first to adopt the early rice direct seeding technology among the large grain growers, which not only saves time and labor, but also ensures the yield.
[0003] However, the existing UAV sowing controls the discharging speed to control the sowing amount. However, the seeds are mainly discharged by rotating the seeder, driving the seeds to be broadcast horizontally or vertically. The seeds are unevenly distributed during broadcasting, which is not suitable for crops with high sowing accuracy requirements. Utility Model Content
[0004] The utility model aims to provide a UAV sowing device, which can evenly distribute the sown seeds and is suitable for crops with high sowing accuracy requirements.
[0005] In order to achieve the above purpose, the technical solution of the utility model is as follows:
[0006] A drone seeding device comprises a silo and a seeding barrel horizontally installed at the bottom of the silo, a discharge trough is provided at the bottom of the seeding barrel, a feed trough connected to the silo is provided at the top of the seeding barrel, a seeding roller is rotatably arranged in the seeding barrel, a seeding trough group facing the discharge trough and the feed trough is provided on the side wall of the seeding roller, the seeding trough group comprises a plurality of seeding troughs distributed along the axis of the seeding roller, a first drive motor for driving the seeding roller to rotate is installed on the outer side of the seeding barrel, and a seed spreading mechanism is provided in the silo.
[0007] Furthermore, the seed spreading mechanism includes a screw rotatably arranged in the silo, a second driving motor driving the screw to rotate is installed on the outside of the silo, a scraper is threadedly connected to the screw, and the bottom of the scraper is arranged close to the feed trough.
[0008] Furthermore, a guide rod is fixedly connected inside the silo, and the scraper is slidably sleeved on the guide rod.
[0009] Furthermore, the sowing slot groups are provided in a plurality of groups, and the plurality of sowing slot groups are evenly distributed around the axis of the sowing roller.
[0010] Furthermore, a mounting frame is provided on the top of the silo.
[0011] Compared with the prior art, the utility model has the following beneficial effects:
[0012] Seeds are placed in a silo, which is installed under the drone. The seeds fall into the sowing trough, and the sowing roller is driven by the first drive motor to rotate, driving the sowing trough with seeds to move to the discharge trough, and the seeds are spread out. The seeds are evenly distributed through multiple sowing troughs. After the seeds are spread for a period of time, the seeds are evenly spread into each sowing trough through the seed spreading mechanism to avoid uneven distribution of seeds in each sowing trough. This is suitable for crops with high sowing accuracy requirements. BRIEF DESCRIPTION OF THE DRAWINGS
