Embodiment 1

[0033] Embodiment 1: This embodiment aims to provide an unmanned aerial vehicle launching device capable of launching Trichogramma ball in the field, such as Figure 1-4 As shown, a Trichogramma launching device based on a drone includes a drone and a launching device. The drone is a quadrotor drone; the drone frame 1 includes a fuselage, For the arm and landing gear, a bee ball storage box 2 is installed at the bottom of the fuselage through a connecting rod. The bee ball storage box 2 is placed between the landing gears; the bee ball storage box 2 is in the shape of a funnel with a large upper and a lower one. The upper and lower parts of the bee ball storage box 2 are respectively provided with a feed port and a discharge port. The discharge port is in a cylindrical shape and is fixedly connected and communicated with the upper end of the throwing device. The bottom plate of the bee ball storage box 2 is inclined The angle is larger than the natural angle of repose of the bee...

Embodiment 2

[0043] Embodiment 2: This embodiment is basically the same as Embodiment 1, and the difference lies in that: this embodiment further illustrates the bee ball storage box, the height of the buffer tube, and the diameter of the buffer tube.

[0044] The capacity of the bee ball storage bin 2 is determined by the size of the bee ball, the pitch of the bee ball, the flying speed of the drone, and the endurance time of the drone. It is not advisable to throw all the bee balls at work, otherwise it will cause missed throws at the end of the mission, and at least 5% of the margin should be left. The calculation formula for the capacity of the bee ball storage box 2 is V=1.05*60D 3 tv / a, where d is the diameter of the bee ball, the unit is cm; t is the drone's flight time, the unit is min; v is the flying speed of the drone, the unit is m / s; a is the pitch of the bee ball, the unit is Is cm. The diameter of the buffer tube 10 is d 1 , The diameter of the buffer tube is equal to the diam...

Embodiment 3

[0046] Embodiment 3: This embodiment is basically the same as Embodiment 1, and the difference lies in that: the entrance edges of the ball-entry hole and the ball-throwing hole are provided with chamfers.

[0047] The velocity of the bee ball relative to the hole during the filling process v r Important, if v r Too small, the bee ball can be smoothly filled into the hole, but it will lead to low delivery efficiency; if v r If it is too large, the bee ball will not have time to fill the hole, causing missed shots. Therefore, in order to ensure that the throwing device has a good throwing performance, it is necessary to study the limit speed at which the bee ball can be filled into the ball hole or the pitching hole. In the process of putting the bee balls, whether the bee balls in the bee ball storage box 2 are filled into the ball hole by the lever and fall into the buffer tube 10, or the bee balls in the buffer tube 10 rotate due to the moving volleyball plate Carrying and char...

Abstract

The invention discloses a trichogramma ball releasing device based on an unmanned aerial vehicle. The trichogramma ball releasing device based on the unmanned aerial vehicle comprises the unmanned aerial vehicle and a releasing device; a ball shifting device comprises a cylindrical ball shifting shell; the upper part of the ball shifting shell is open; the opening communicates with a material outlet; a shaft hole and a ball inlet hole are correspondingly formed in the center and eccentric position of a bottom plate of the ball shifting shell; a shifting rod is arranged in the ball shifting shell; a circular hole and a ball outlet hole are correspondingly formed in the center and the eccentric position of a top plate of a ball releasing shell; a movable ball arranging disc is arranged in the ball releasing shell; a semicircular arc shifting opening is formed in the external peripheral edge of the movable ball arranging disc; a ball releasing opening is formed in the eccentric position at the bottom of the ball releasing shell; the ball inlet hole and the ball outlet hole communicate with each other through a caching pipe; a U-shaped shaft coupling is correspondingly fixed on a shifting rod rotating shaft and a movable ball arranging disc rotating shaft so that the shifting rod rotating shaft and the movable ball arranging disc rotating shaft are enabled to synchronously rotate;a steering engine and a control mechanism are connected to form an unmanned aerial vehicle and steering engine control system; and therefore, the workload of operation personnel is reduced, the operation time is shortened, the releasing is accurate, and the releasing speed is high.

Description

Technical field: [0001] The Trichogramma dropping device of the present invention belongs to the technical field, and specifically relates to a Trichogramma dropping device based on a drone. Background technique: [0002] Trichogramma is currently the most widely used egg parasitic wasp in the world for production and release. After emergence in the field, female Trichogramma will actively look for pest eggs, pierce the pest egg shells with oviposit tubes, lay their eggs in them and absorb the nutrients of pest eggs to grow and grow. The parasitic pest eggs cannot develop normally, so the purpose of pest control is achieved in this way. This method can effectively control pests and has achieved certain economic, ecological and social effects. [0003] Trichogramma is mainly released by "submerged", and the existing release method is to rely on artificial walking in the field to hang the bee card to release. This method has low efficiency and poor uniformity; it is more difficult...
