Description

Technical Field

[0001] The invention discloses an elevated forestry sprayer, belonging to the field of sprayers. Background Art

[0002] In recent years, with the development of the national economy, the domestic people's awareness of environmental protection has gradually increased. At the same time, the national strategy of protecting the environment has been steadily advancing, and forestry development has become one of the main means of environmental protection in my country.

[0003] Most trees in northern my country can grow to about 25 meters, with a crown diameter of 5 to 6 meters. In order to protect trees from pests or provide conservation pesticides, airplanes are often used to spray pesticides on a large scale in forestry areas or sprayers are used to directly hit the crowns from the ground.

[0004] However, during the spraying process, it is best to spray the pesticide on every leaf of the tree, otherwise it is easy for pests, such as the gypsy moth, to hide in the tree crown. Although it has a certain insecticidal and conservation effect, the effect is greatly reduced, resulting in great waste. Summary of the invention

[0005] In order to solve the above technical problems, the present invention provides an elevated forestry sprayer capable of spraying pesticides within a tree crown.

[0006] In order to achieve the above technical objectives, the technical solution provided by the present invention is:

[0007] The elevated forestry sprayer comprises: a tractor, an aerial frame and a spray module; the aerial frame is vertically fixed on the tractor, the aerial frame is a vertical rod, the spray module is fixed on the upper part of the aerial frame, and the spray module is connected to the high-pressure water pump on the tractor.

[0008] The aerial frame comprises: a fixed rod and an elastic rod, wherein the fixed rod is a hollow tube, an elastic rod is fixed to the upper end of the fixed rod, the elastic rod is a hollow tube, and a spray module is fixed to the upper part of the elastic rod.

[0009] The spray module comprises: a spray bracket, an atomizing nozzle and a water supply hose. The spray bracket is a tubular structure with a sealed upper portion. The spray bracket (31) is fixedly connected to the upper end of the elastic rod. A plurality of atomizing nozzles are fixed on the outer wall of the spray bracket. Each atomizing nozzle is connected to the water supply hose. The water supply hose is arranged in the spray bracket and extends to the lower end of the elastic rod.

[0010] The length of the water supply hose is not less than 1.2 times the total length of the elastic rod and the spray module.

[0011] The spray bracket includes: a bracket tube body and a protrusion protection body; the bracket tube body is a vertically arranged tubular structure, and a plurality of protrusion protection bodies are fixed on the outer wall of the bracket tube body in sequence from bottom to top, and the protrusion protection body is an annular protrusion, and a plurality of atomizing nozzles are inlaid on the tube wall of the bracket tube body of adjacent protrusion protection bodies, and the nozzle tip of the atomizing nozzle is located in a groove between two protrusion protection bodies.

[0012] The fixing rod comprises a plurality of connecting rods, which are fixedly connected end to end in sequence to form the fixing rod, and the fixing rod is no higher than 25m.

[0013] The spray module is 3 to 4 meters long, and the elastic rod is 6 to 8 meters high.

[0014] The elastic rod is made of glass fiber or carbon fiber or a composite material of glass fiber and carbon fiber.

[0015] The lower end of the elastic rod is inserted into the pipe opening at the upper end of the fixed rod, and the upper end of the fixed rod is fixedly connected to the elastic rod through a fastening nut.

[0016] The support tube body is made of rubber.

[0017] A connecting pipe is arranged inside the fixing rod, and the connecting pipe connects the water supply hose with the high-pressure water pump.

[0018] Compared with the prior art, the present invention has the following beneficial effects:

[0019] 1. The present invention adopts a high-altitude frame to lift the spray module to the same height as the tree crown, ensuring that the pesticide is sprayed on the leaves inside the tree crown to the greatest extent during the operation of the spray module, thereby improving the efficiency of pesticide spraying and reducing the growth and reproduction of forest pests.

[0020] Second, the present invention adopts an elastic rod. When the spray module moves between the tree crowns and encounters branches blocking it, the elastic rod deforms to allow the spray module to pass through the blocking branches smoothly, ensuring smooth operation during the pesticide spraying process.

[0021] 3. The present invention adopts a water supply hose, which is convenient for cooperating with the deformation of the elastic rod. At the same time, the water supply hose has sufficient margin during the deformation of the elastic rod to prevent the pipeline from being torn off.

[0022] Fourth, the present invention adopts a raised protective body to reduce the damage of branches to the atomizing nozzle. BRIEF DESCRIPTION OF THE DRAWINGS
