Problems solved by technology

[0006] Although the above-mentioned drone sowing operation has improved the uniformity of sowing compared with manual sowing, it still has the following shortcomings: 1) After the seeds are discharged from the seed metering device, due to the interference of the rotor wind, the position of the seeds falling is uncontrollable and the seeds fall evenly. The performance is not good enough; 2) The seeds fall on the surface, which is easy to be eaten by birds and rodents or washed by rain, resulting in seedling shortage; 3) The seed meter is easy to arch and block; It is difficult to form rows and holes, the poor ventilation and air permeability of crops is easy to breed diseases and insect pests, and it is not convenient for field management during the growth period, etc.
This device adopts the friction wheel to accelerate the seeds, which reduces the interference of the rotor wind on the whereabouts of the seeds, but the device has the following disadvantages: 1) there are many types of crops, and there are differences in the external dimensions of the seeds of different varieties of the same crop, and the size and shape of the seeds of the same variety are different. It is also difficult to achieve the same, and the distance between the friction wheels in the prior art cannot be adjusted adaptively with the different shapes of the seeds, which may easily cause damage or blockage; The limit is large, and the seeds cannot be lined up into the friction wheel, which is prone to the problem of seed jamming; 3) During operation, it is necessary to adjust the motor according to the pitch angle, so it is difficult to achieve precise sowing
Although this method can increase the initial velocity of the seed exit, the acceleration range is limited, and it is still susceptible to external wind interference such as the rotor wind field when the seeds are dropped, and the structure is complex, and the weight of the whole machine is relatively large. For UAVs with high load requirements Poor applicability

Embodiment 1

[0097] A kind of sowing method of row-type seeding drone, such as Figure 9 shown, including the following steps:

[0098] S1: Calibration parameters: Calibrate and store the control parameters of the row-type sowing;

[0099] The row seeding control parameters are determined by the following relationship models: the relationship model between the working height, the shooting angle and the row spacing, the relationship model between the seeding frequency of the burst sowing module, the sowing operation speed and the plant spacing, the friction wheel speed, and the working height The relationship model with the depth of seed penetration into the soil;

[0100] S2: Centralized seed supply: when sowing, the seeds enter the seed meter from the seed box, and the seed discharge is controlled by the seed meter;

[0101] S3: Sowing by the seed divider: the seeds discharged by the seed meter are divided into multiple parts, and are guided and dispersed to each burst sowing module by ...

Embodiment 2

[0111] Such as figure 1 , a row-type seeding drone applied to the row-type sowing method, comprising a drone body 1, a seed box 2, a seed meter 3, a seed divider 4 and several The burst seeding module 5; the seed meter 3 is used to discharge the seeds to the seed divider 4; the seed divider 4 is used to disperse and transport the seeds to the corresponding burst seeding module 5; the burst seeding module 5 Distributed side by side in a fan shape, the burst seeding modules 5 are used for queuing up the seeds and accelerating their ejection.

[0112] In this embodiment, the row-type sowing UAVs are as follows from top to bottom: seed box 2, UAV body 1, seed meter 3, seed divider 4 and five burst seeding modules 5; The seeds in the box 2 are discharged into the seed divider 4 through the seed meter 3. The seed divider 4 divides the seeds into five parts and transmits them to the corresponding burst seeding module 5. The burst seeding module 5 can accelerate the seeds After inje...

Abstract

The present invention relates to the field of agricultural aviation technology, in particular, to a method of projecting seeding and a method of projecting sowing UAVs, which are used to solve the problem of external problems such as rotor wind and other problems in the prior art of using UAVs for sowing. The problems of airflow interference, inaccurate sowing, and inability to better meet the sowing requirements of rows and holes; the present invention provides a sowing method for a row-type sowing drone, the steps of which are: calibration parameters, centralized seed supply, and sorting Sowing by device and row-type sowing; the present invention also provides a row-type sowing unmanned aerial vehicle applied to the row-type sowing method.

Description

technical field [0001] The present invention relates to the technical field of agricultural aviation, and more specifically, to a row-type sowing method and a row-type sowing unmanned aerial vehicle applying the method. Background technique [0002] In recent years, with the continuous advancement of UAV technology, the accuracy and stability of its flight routes have been continuously improved, and its application in agricultural production has become more and more extensive. Compared with ground machinery, the use of drones for sowing has better trafficability, avoids vehicle trapping and damage to field ridges, and drones have fast seeding speed and simple operation. They are gradually being accepted by farmers and have become a new The unique sowing method is especially suitable for paddy fields with small plots, large height differences, and deep mud feet in southern my country. [0003] At present, the sowing operation of drones is mainly sowing, and the seeding device...
