Problems solved by technology

However, at present, the small unmanned rotorcraft has a small weight and a short time in the air, which has become a technical bottleneck for application and promotion.
The accident rate of small unmanned rotorcraft is high when it takes off and lands. Due to the small load, high-frequency take-off and landing operations during spraying operations will increase accident costs and directly affect operational efficiency.

Embodiment 1

[0024] like figure 1 , figure 2 , image 3 As shown, a land-air combined agricultural spraying device includes an aircraft 1 and a transport vehicle 7; the transport vehicle 7 is provided with a hoisting mechanism support rod 4, a power supply system 5, a liquid storage tank 6 and a pressure pump 8, and the hoisting mechanism supports The upper end of the rod 4 is fixed with a hoisting mechanism 3, and the hoisting mechanism 3 is used to control the retractable length of the connecting pipeline 2; the internal channel 9 is divided into two parts: a water circuit and an electric circuit, and the medicinal liquid of the liquid storage tank 6 is pumped into the interior by the pressure pump 8 The water circuit of the channel 9, the output power line of the power supply system 5 enters the circuit of the internal channel 9, the internal channel 9 is connected with the connecting pipeline 2 through the interior of the support rod 4 of the hoisting mechanism, and the connecting pi...

Embodiment 2

[0030] The principle is the same as in Example 1. If the spraying radius is too large, the weight of the longer connecting pipeline 2 will affect the normal flight of the aircraft 1. One connecting pipeline 2 can be used to connect multiple aircraft 1 in series. The weight of the connecting pipeline 2 is determined by Multiple aircraft 1 share, such as Figure 4 shown.

Embodiment 3

[0032] The principle is the same as in Example 1, two or more connecting pipelines 2 can be assembled, and multiple areas can be sprayed at the same time to improve work efficiency, such as Figure 4 shown.

Abstract

The invention discloses an air-ground combined agricultural spraying device and application of the air-ground combined agricultural spraying device. The air-ground combined agricultural spraying device comprises an aircraft, connecting pipelines, a winch mechanism, a winch mechanism supporting rod, a power system, a liquid pesticide storage tank, a transport vehicle, a pressure pump, an inner passage, a propeller, a propeller beam, a propeller drive motor, an aircraft bracket and spray heads. According to the air-ground combined agricultural spraying device, the large-size heavy liquid pesticide tank, the pressure pump and the power system are installed on the transport vehicle, a spraying mechanism is installed on the small unmanned rotorcraft, and an air device and a ground device are connected through hoses and wires. In this way, aerial spraying in a limited area within ultra-long auto-hover time is achieved, and meanwhile long-distance ground transportation of an aircraft is achieved.

Description

technical field [0001] The invention relates to the field of agricultural machinery, in particular to a land-air combined agricultural spraying device and its application. Background technique [0002] Agricultural aviation spraying has great application prospects. For small and medium-sized plots where airports cannot be built or complex terrains, it is more suitable to use small rotorcraft for spraying operations. A hot spot in the field of aviation spraying. However, at present, small unmanned rotorcraft has low carrying weight and short stay in the air, which has become a technical bottleneck for application and promotion. Small unmanned rotorcraft has a high accident rate during take-off and landing. Due to the small load, the high-frequency take-off and landing operations during spraying operations will increase the accident cost and directly affect the operation efficiency. SUMMARY OF THE INVENTION [0003] The purpose of the present invention is to overcome the s...
