Description

Technical Field

[0001] This invention relates to the field of agricultural sowing and fertilization machinery technology, and in particular to a rice-fertilizer-oil spreading device mounted on a drone. Background Technology

[0002] With the development of national agriculture, corresponding farmland planting policies have been formulated according to the characteristics of different regions. Many regions have promoted crop rotation systems such as "rice-rapeseed" or "rice-rice-rapeseed". With the rapid development of agricultural drone technology, agricultural drones have greatly improved the efficiency of sowing and fertilization operations in agricultural production. By mounting seeding devices on drones and using the drones to fly with seeding devices, seeds or fertilizers can be efficiently sown into the fields.

[0003] In the existing technology, the types of drone seeding devices are mostly centrifugal discs, which have good versatility and can be used for granular fertilizers and crop seeds, with a wide range of applications, but the effective width is small and the working efficiency is low.

[0037] The first motor is mounted on the support leg;

[0038] A coupling is used to connect to the first motor;

[0039] Mounted bearings are installed at both ends of the conveying screw;

At a spreading angle of 100°, it has an effective spreading width of 7.5m, thus improving work efficiency.

[0075] The spreading component 420 is rotatably mounted on the base plate 410 and is used to receive materials and spread them into the field.

[0076] The second transmission component 430 is mounted on the base plate 410 and connected to the spreading component 450 to drive the spreading component 450 to perform oscillating spreading.

[0077] It should be noted that in some embodiments, a loading area for the material box 200 is reserved in the middle area of ​​the multi-rotor drone 100, so that the material box 200 can be installed in this area. This can better ensure the balance of the multi-rotor drone 100 during flight. A spiral metering mechanism 300 is provided below the material box 200. The spiral metering mechanism 300 is fixedly connected to the material box 200. The fixed connection can be a threaded connection or a snap-fit ​​connection. The specific connection method is selected according to the actual needs.

[0078] Optionally, the support leg 110 is fixedly connected to the base plate 410, and the oscillating tube spraying mechanism 400 is installed on the base plate 410 and kept at a certain distance from the ground. The support leg 110 is configured to raise the multi-rotor drone 100 to a certain height, and when the drone is placed on a horizontal ground, the oscillating tube spraying mechanism 400 will not touch the ground when it is running.

[0079] It should be noted that the dissemination component 420 includes:

[0080] Base 421;

[0081] The rotating groove 422 is rotatably connected to the base 421. The upper end of the rotating groove 422 is provided with a third feed port 4221, which is connected to the discharge port of the spiral metering mechanism 300. The rotating groove 422 is provided with a third discharge port 4222. In this embodiment, the center line angle between the third discharge port 4222 and the third feed port 4221 on the rotating groove 422 is 80 degrees. This angle is the optimal parameter for the oscillating tube spreading mechanism, which can obtain the optimal spreading uniformity.

[0082] The slide rail 423 is fixedly connected to the rotating groove 422;

[0083] The oscillating tube 424 is fixedly connected to the rotating groove 422. One end of the oscillating tube 424 is provided with a fourth feed port 4241, which is connected to the third discharge port 4222.

[0084] It should be noted that the slide rail 423 is provided with an arc-shaped slide groove 4231, and the second transmission assembly 430 includes:

[0085] The second motor is mounted on the base plate 410;

[0086] Crank 431 is connected to the output shaft of the second motor;

[0087] The crank shaft 432 is fixedly connected to the crank 431;

[0088] The slider 433 is fixedly connected to the crank shaft 432. The end of the slider 433 away from the crank shaft 432 is installed in the arc-shaped groove 4231. The second motor rotates to drive the crank 431 and the crank shaft 432 to rotate, which drives the slider 433 to move in the arc-shaped groove 4231 to drive the arc-shaped groove 4231 to swing back and forth, thereby increasing the spreading range.

[0089] It should be noted that the oscillating tube 424 is also provided with a fourth discharge port 4242 and a uniform material port 4243, and a material distribution bar 4244 is provided at the fourth discharge port 4242.

[0090] It should be noted that the surface of the oscillating tube 424 is provided with at least two material distribution ports 4243, which can increase the spreading width of the material. The material distribution strip 4244 can disperse the material at the fourth discharge port 4242 and improve the uniformity of spreading. In this embodiment, the length of the oscillating tube 424 is 250mm, which is an optimal parameter and can obtain a relatively large width under the interference of the UAV wind field.

[0091] It should be noted that the spiral metering mechanism 300 includes:

[0092] The conveying assembly 310 is connected to the receiving cavity 210 and is used to convey the material in the receiving cavity 210 to the oscillating tube spreading mechanism 400.

[0094] It should be noted that the conveying assembly 310 includes:

[0095] The spiral shell 311 has a first inlet 3111 and a first outlet 3112. The spiral shell 311 is provided with a blade 3113 that cooperates with the distribution plate 220 to divide the material passing through the inlet 3111 into two parts.

[0096] A spiral groove 312 is installed inside the spiral housing 311. The spiral groove 312 has a second inlet 3121 and a second outlet 3122, wherein the second inlet 3121 communicates with the first inlet 3111 and the second outlet 3122 communicates with the first outlet 3112.

[0097] The conveying screw 313 is coaxially installed in the spiral groove 312. The surface of the conveying screw 313 is provided with spiral blades 3131 along the length direction, which are used to quantitatively convey materials from the feed port 3121 to the second discharge port 3122. Specifically, under the restriction of the cylindrical space inside the spiral groove 312 and the forced drive of the spiral blades 3131, it has good adaptability to rice seeds, rapeseed seeds and inorganic granular fertilizer.

[0098] A movable feed vane 314 is installed inside the spiral groove 312 to control the flow of the feed inlet 3111.

[0099] It should be noted that the first transmission assembly 320 includes:

[0104] It should be noted that the lower end of the material container 200 is provided with a material distribution plate 220, which is used to divide the material in the receiving cavity 210 into two parts.

[0105] The rice fertilizer and oilseed spreading device mounted on an unmanned aerial vehicle according to the present invention has at least the following advantages compared with the prior art:

[0106] By using multi-rotor drones as carriers, the efficiency of sowing and fertilization operations in agricultural production can be improved. The device's conveying screw, with its spiral blades, has excellent adaptability for conveying materials and can be used for rice / rapeseed planting as well as the application of granular drone fertilizer, thereby improving the operational efficiency and utilization rate of agricultural drones.

[0107] This invention employs a swivel tube structure for the spreading mechanism, which distributes the spread material in a trapezoidal symmetrical pattern in the field. The spread material is symmetrically distributed with respect to the forward path, and the spreading angle can reach 100°, resulting in a wider effective spreading width and improved work efficiency.

[0108] The invention has been verified through actual measurements, and its effects are shown in Table 1 below.

[0109] Table 1 shows the seeding effect results at different seeding angles in this embodiment.

[0110]

[0111] In the table above, a larger coefficient of variation for spreading uniformity indicates a less uniform spreading effect.

[0112] Actual measurements show that increasing the swing angle to the range of 60° to 80° does not significantly increase the effective sowing width, and the sowing effect fluctuates greatly within this angle range. However, when the swing angle is increased to 90° to 100°, not only is there a significant increase in the effective sowing width, but the sowing effect is also more stable and uniform. Therefore, the rice-fertilizer-oilseed dual-purpose sowing device of this application not only improves work efficiency but also enhances sowing uniformity.

[0113] Example 2

[0114] This embodiment makes further improvements based on embodiment 1, and provides a rice fertilizer and oil spreading device mounted on a drone, wherein each side of the surface of the spiral groove 312 is provided with at least one second feed port 3121;

[0115] The spiral blades 3131 are spiral blade segments with different spiral directions, used to convey materials from multiple second feed ports 3121 to the second discharge ports 3122. In this embodiment, for sowing materials with a large usage per acre, such as rice and fertilizer, the second feed ports 3121 are always open, and the required sowing amount is controlled by adjusting the corresponding rotation speed. For rapeseed planting, which requires a smaller usage per acre, the movable feed distribution plate 314 can be controlled to close one side of the second feed port 3121, and the rotation speed of the first motor can be adjusted to meet the required sowing amount per acre for rapeseed planting. It is worth mentioning that in this embodiment, the rotation speed of the first motor should not be too low, as this will lead to poor conveying stability.
