Background technique

Plant protection drones, as the name suggests, are unmanned aerial vehicles used for agricultural and forestry plant protection operations. This type of unmanned aerial vehicle consists of an aircraft platform (fixed-wing, helicopter, multi-axis flying chess), navigation flight control and spraying mechanism. Remote control or navigation flight control is used to achieve spraying operations, but spraying chemicals, seeds, powders, etc., among which the most common is spraying chemicals. The existing chemical spraying mechanism includes a medicine storage box. The medicine storage box is pumped out by a pump, and finally sprayed out through multiple nozzles. In this case, the spraying range is often small, and some tall trees sometimes need to be sprayed from the side. Spraying, the existing spraying mechanism can not be achieved.

Utility model content

The purpose of the utility model is to solve the deficiencies in the prior art, and to provide a plant protection drone spraying mechanism with a wider spraying range and at the same time side spraying.

The utility model is achieved through the following technical solutions:

That is, a plant protection drone spraying mechanism, including a fuselage, a plurality of arms on the fuselage, a propeller on the arms, two frames at the lower end of the fuselage, and supports are connected between the two frames A medicine storage box is arranged on the support rod, and a medicine pump is arranged at the lower end of the support rod. The medicine pump is connected with the medicine storage box through a hose, and two electric telescopic rods are symmetrically arranged at the lower end of the support rod. The ends of the electric telescopic rods are connected with a horizontally arranged connecting rod. A liquid outlet pipe and an installation head are arranged between the two connecting rods. The liquid outlet pipe and the installation head are connected with each other. The rotating pipe is connected with the upper part of the mounting head by a bearing, the upper end of the bearing is also installed with a bearing end cover, the lower end of the rotating pipe is connected with two spray pipes through a tee joint, and the spray pipes are provided with multiple For atomizing nozzles, the atomizing nozzles on the two spray pipes are inclined in different directions.

The spray pipe in the utility model can rotate spontaneously under the spray reaction force, and under the action of centrifugal force, the spraying range will be wider, and the atomizing nozzles are all inclined, which can take into account the downward spraying and Spray sideways.

Further preferably, an annular liquid outlet is provided on the rotating pipe, and the rotating pipe is communicated with the liquid outlet pipe through the annular liquid outlet.

Further preferably, the connection modes between the liquid outlet pipe and the installation head and the rotary pipe and the installation head are all plug-in connections.

Compared with the prior art, the beneficial effects that the utility model has are:

The spray pipe in the utility model can rotate spontaneously under the spray reaction force, and under the action of centrifugal force, the spraying range will be wider, and the atomizing nozzles are all inclined, which can take into account the downward spraying and Spray sideways.

Detailed ways

The specific embodiments of the present utility model will be described in further detail below with reference to the accompanying drawings.

As shown in Figures 1 to 5, a plant protection drone spraying mechanism includes a fuselage 1, a plurality of arms 2 are arranged on the fuselage 1, a propeller 3 is arranged on the arms 2, and the lower end of the fuselage 1 is provided with Two racks 4, a support rod 8 is connected between the two racks 4, a medicine storage box 5 is arranged on the support rod 8, and a medicine pump 7 is arranged at the lower end of the support rod 8, and the medicine pump 7 passes through a hose 6 is connected to the medicine storage box 5, the lower end of the support rod 8 is also symmetrically provided with two electric telescopic rods 19, and the end of each electric telescopic rod 19 is connected with a horizontally arranged connecting rod 10, between the two connecting rods 10 There is a liquid outlet pipe 9 and a mounting head 16, the liquid outlet pipe 9 and the mounting head 16 are communicated with each other, and a rotating pipe 11 is provided through the mounting head 16 up and down, and a rotating pipe 11 and the upper part of the mounting head 16 pass through a The bearing 17 is connected, the upper end of the bearing 17 is also installed with a bearing end cover 18, and the lower end of the rotating pipe 11 is connected with two spray pipes 13 through a tee joint. The atomizing nozzles 14 on the spray pipe 13 are inclined in different directions.

The rotary pipe 11 is provided with an annular liquid outlet 15 , and the rotary pipe 11 communicates with the liquid outlet pipe 9 through the annular liquid outlet 15 .

The connection modes between the liquid outlet pipe 9 and the mounting head 16 and between the rotating pipe 11 and the mounting head 16 are all plug-in connections.

work process:

The prepared medicine is loaded into the medicine storage box 5 in advance, the plant protection drone flies over the spray area, and the two electric telescopic rods 19 are extended, so that the height of the spray pipe 13 is lower than the lower end of the rack 4, and the medicine is drawn. The pump 7 pumps the medicine in the medicine storage box 5 into the liquid outlet pipe 9, and then the medicine enters the rotary pipe 11 through the annular liquid outlet 15, and finally enters the two spray pipes 13 by the atomizing nozzle 14. After spraying, after the spraying operation is completed, the two telescopic rods 19 are retracted upward, so that the height of the spray pipe 13 is higher than the lower end of the rack 4, which facilitates the smooth landing of the plant protection drone. Wherein, there is a certain gap between the contact surface of the rotating tube 11 and the connecting head 16, and there will be a little drug leakage, but this will not affect the application of the present invention.

In the description of the present invention, the orientation or positional relationship indicated by the terms "inner", "outer", "upper", "lower", "top", "bottom", etc. are based on the orientation or positional relationship shown in the accompanying drawings , is only for the convenience of describing the present invention, rather than requiring the present invention to be constructed and operated in a specific orientation, so it cannot be construed as a limitation on the present invention.
