Description

Technical Field

[0001] The utility model relates to the technical field of orchard pollination machinery and equipment, and in particular to a tethered electrostatic pollination drone. Background Art

[0002] Kiwifruit is a dioecious plant, and the pollination effect determines the fruit yield and quality. my country has abundant kiwifruit varieties and a large planting area. The pollination flowering period of female kiwifruit plants is only 3 to 5 days, and the pollination operation time window is narrow. Handheld assisted pollination devices have high labor intensity, low operation efficiency, and high pollen consumption. With the reduction of agricultural labor, mechanized and intelligent operation equipment has become an inevitable choice for replacing human labor.

[0003] At present, there are two main types of handheld electric pollination devices. One is the wind-transported pollinator for single-flower target operation (such as CN113924974A, CN112293244A, etc.), which is operated by manually finding flowers and targeting, and one-handed point pollination, and each operation can only complete the pollination of one flower; the other is the wind-transported duster for trellis diffuse spraying (such as CN212660785U, etc.), which spreads pollen to the canopy space through a fan, and the operation efficiency is improved, but the utilization rate of pollen is low, and generally multiple operations are required to ensure sufficient pollination. Due to the heavy weight of the duster, the labor intensity is high. Kiwifruit mainly adopts the trellis planting mode, the canopy is relatively flat, and most of the female flowers grow drooping. Kiwifruit pollination devices for mechanized and precise operations generally adopt the target pollination operation mode, obtain the spatial coordinate position of the flower through the identification system, and use the motion control of the mechanical target mechanism to achieve single flower targeting, and then the pollinator moves to achieve flower-by-flower pollination. Since this type of pollination device needs to be mounted on a mobile platform, the undulation of the ground will affect the posture of the mobile platform, and the continuous moving operation mode (such as: CN210017334U, CN216626995U) will reduce the accuracy of flower positioning and target positioning, and the step-by-step operation mode (such as: CN216753104U) has low operating efficiency. In addition, the mechanical target mechanism is rigidly connected to the mobile chassis, and the operating space is small, which limits the improvement of the target pollination operation efficiency.

[0004] Therefore, there is an urgent need for a tethered electrostatic pollination drone to solve the problems of low target pollination efficiency and low pollen utilization in the prior art. Utility Model Content

[0052] In a specific embodiment of the present application, the drone 300 is a quad-rotor drone, and several drones 300 are provided. It is understandable that the drone 300 includes but is not limited to a quad-rotor drone.

The operation efficiency is improved by connecting several drones 300 to a mobile platform. Preferably, several pollen bottles 110 can be set on the mobile platform, each pollen bottle 110 is connected to one drone 300 or multiple drones 300, and one pollen bottle 110 can also be set, each pollen bottle 110 is connected to several drones 300.

[0053] In a specific embodiment of the present application, the windshield 310 and the mounting plate 320 are fixed by bolts, and the mounting plate 320 and the drone 300 are connected by bolts.

[0054] The working principle of the utility model is as follows: before pollination, the operator needs to put pollen into the pollen bottle 110, control the mobile platform 100 to move the drone 300 to the bottom of the kiwifruit trellis; manually guide the drone 300 to fly directly under the flower through the remote control 700, so that the pollen outlet tube 111 is aimed at the flower. Then start the air pump 200 and the electrostatic generator 400, and the airflow in the air inlet pipe 210 blows the pollen in the pollen bottle 110 into the pollen delivery tube 112 and the pollen outlet tube 111. The connecting line of the discharge electrode 410 is arranged in the pollen outlet tube 111. The airflow carries the pollen through the high-voltage electric field generated by the discharge of the discharge electrode 410 at the pollen outlet, so that the pollen carries static electricity. At the same time, under the action of high-voltage static electricity, an electrostatic field is generated between the charged pollen and the female flower stigma, so that the charged pollen grains improve the targeting and stigma attachment rate of the pollen transport process under the dual action of the airflow field and the electrostatic field, thereby improving the utilization rate of the pollen and the success rate of pollination. When all the flowers above the drone 300 have been pollinated, the operator controls the drone 300 to move to the next flower to continue pollination.

[0055] In summary, the mobile platform 100 can drive the pollen bottle 110 to move in multiple directions on the ground, which is very convenient; the drone 300 can drive the pollen outlet tube 111 for pollination, which improves the pollination rate compared to traditional manual pollination; the windshield 310 can reduce the influence of surrounding air turbulence, improve the targeting of pollen after spraying, increase the probability of the stigma capturing pollen under the action of the pollen electrostatic field, and improve the utilization rate of pollen; the electrostatic generator 400 and the discharge electrode 410 can make the pollen carry static electricity, generate an electric field force between the pollen and the female flower stigma at a certain distance, and cooperate with the air pump 200, which makes it easier for the pollen to be adsorbed to the female flower stigma to complete fertilization, reduces the ineffective dispersion of pollen, and improves the efficiency of pollination.

[0056] Furthermore, a battery pack 500 is provided on the mobile platform 100, which can conveniently power the air pump 200 and the electrostatic generator 400, and is more convenient to use than directly connecting to an external power source. The controller 600 is electrically connected to the battery pack 500, and can control the battery pack 500 to power the air pump 200 and the electrostatic generator 400; the controller 600 is electrically connected to the mobile platform 100, that is, the controller 600 is electrically connected to the driving component of the mobile platform 100, and can control the movement parameters such as the moving direction and moving speed of the mobile platform 100; the controller 600 is electrically connected to the drone 300, and can control the ascending and descending height, flight direction and flight speed of the drone 300, and the controller 600 is wirelessly connected to the remote controller 700, and can remotely control the controller 600 through the remote controller 700, so as to realize the control of the above parameters by the controller 600, which is highly intelligent and convenient.

[0057] Furthermore, the provision of a circular bracket 330 is convenient for fixing the pollen outlet pipe 111 and the distance between the pollen outlet pipe 111 and the inner wall of the windshield 310. The pollen outlet pipe 111 and the pollen delivery pipe 112 are deformable, which can facilitate the reversing flight of the drone 300. When the drone 300 and the mobile platform 100 are not in a vertical straight line, pollination is not affected. The mobile platform 100 and the drone 300 are flexibly connected by the pollen outlet pipe 111 and the pollen delivery pipe 112, which eliminates the influence of the ground on the pollination operation of the flight unit and expands the pollination operation range of the drone 300.

[0058] Furthermore, by fixing the pollen outlet tube 111 and the pollen transport tube 112 with a dividing clip, the pollen outlet tube 111 and the pollen transport tube 112 can be easily connected and disassembled. The ground wire 120 can conduct the static electricity generated by the electrostatic generator 400 into the earth to avoid excessive accumulation of static electricity and damage to equipment or personnel. Two discharge electrodes 410 are arranged on the pollen transport tube 112, so that the pollen can carry more static electricity, so that it is easier to adsorb to the female flower stigma, thereby improving the pollination efficiency. The drone 300 includes but is not limited to a four-rotor drone 300. The operation efficiency is improved by connecting multiple drones 300 to a mobile platform.
