Problems solved by technology

[0002] At present, in agriculture and forestry, pests and diseases are very troublesome things. The existing methods of spraying pesticides, or spraying plants one by one manually, are inefficient, incomplete insecticide, and cause a lot of waste, which is not suitable for large-scale cooperative production; Renting an aircraft to spray pesticides is limited by the altitude requirements of the aircraft and cannot fly close to the ground. There is a lot of waste of pesticides, polluting the environment and air, and the rent is very expensive

Embodiment 1

[0036] Example 1, such as image 3 The steady flow valve 5 includes a drogue valve seat 9 arranged at the bottom of the water tank 4 with a large bottom and a small top; The guide frame 8 in 4, the buoy airbag 7 floating in the guide frame 8 and the lower end connected to the upper end of the cone valve 6, as preferably, can include an upside-down upper electric screw that is arranged on the top of the water tank 4 and is used to push down the buoy airbag 7 10;

[0037] After the water tank 4 was filled with liquid, the buoyancy of the buoy air bag 7 was greater than the sum of the gravity of the cone valve 6 and the positive pressure of the liquid on the cone valve 6 upper surface.

[0038] When the pesticide is filled, the buoy air bag 7 floats up, so that the cone valve 6 is in sealing contact with the taper sleeve valve seat 9 to realize sealing. The screw rod 10 moves downward for a displacement, thereby pressing down the buoy airbag 7, and the buoy airbag 7 moves downw...

Embodiment 2

[0039] Example 2, Figure 4 The steady flow valve 5 includes a drogue valve seat 9 arranged at the bottom of the water tank 4 with a large bottom and a small top; The flow sensor 16, the processor 17 arranged on the UAV 1, and the opening driving electric screw 18 on the upper part and used to drive the opening of the adjusting spool 15 up and down.

[0040] The flow sensor 16 is electrically connected with the processor 17, and the processor 17 is electrically connected with the opening driving electric screw 18 through the controller. The flow sensor 16 receives the flow signal, and the processor drives the electric screw 18 through the controller to control the opening, and adjusts the opening of the spool 15 to keep increasing, so as to ensure uniform flow. Valves such as electronically controlled ball valves can also be used to achieve precision. control.

[0041] A booster valve 13 is also arranged between the temporary storage chamber 11 and the water nozzle 14 , and th...

Abstract

The invention relates to an unmanned aerial vehicle used for spraying pesticides in agriculture and forestry. The unmanned aerial vehicle used for spraying pesticides comprises the unmanned aerial vehicle and a liquid spraying device arranged on the unmanned aerial vehicle. The liquid spraying device comprises a water tank arranged on the upper end of the unmanned aerial vehicle, at least three water spraying nozzles arranged below the unmanned aerial vehicle, and water pipes used for conveying liquid in the water tank into the water spraying nozzles. Since the unmanned aerial vehicle is used for spraying pesticides, low-altitude flight and automatic navigation are realized, pesticides are prevented from being carried away by wind and polluting air, pesticide waste is avoided, remote control is convenient, and cost is low; the water pipes are provided with electric on / off switches which are standard members; and a camera is arranged on the unmanned aerial vehicle, so remote-control observation can be conveniently realized, and a top view of the conditions of farmland or forest land can be acquired.

Description

technical field [0001] The invention relates to an unmanned aerial vehicle for spraying pesticides in agriculture and forestry. Background technique [0002] At present, in agriculture and forestry, pests and diseases are very troublesome things. The existing methods of spraying pesticides, or spraying plants one by one manually, are inefficient, incomplete insecticide, and cause a lot of waste, which is not suitable for large-scale cooperative production; Renting an aircraft to spray pesticides is limited by the height requirements of the aircraft and cannot fly close to the ground. There is a lot of waste of pesticides, polluting the environment and air, and the rent is very expensive. Contents of the invention [0003] In view of the above, the technical problem to be solved by the present invention is generally to provide an agricultural and forestry tool with reasonable design, low cost, durable, safe and reliable, easy to operate, save time and effort, save money, co...
