Self-propelled air-conveying type orchard spraying machine

Abstract

The invention discloses a self-propelled air-driven orchard sprayer, which comprises a frame, a power system arranged on the frame, a spray system arranged at the tail of the frame, a transmission system connected between the power system and the spray system, The cockpit set at the head of the frame and the walking wheels set under the frame, the spray system includes a liquid medicine tank set on the frame to hold the liquid medicine, a diaphragm pump connected to the liquid medicine tank through the diaphragm pump inlet pipe, A diaphragm pump outlet pipe connected to the diaphragm pump outlet and a high-pressure spray mechanism arranged on the frame and connected to the diaphragm pump outlet pipe. The spraying system of the present invention adopts high-pressure spiral air delivery and automatic swing to carry out the spraying operation, which is the first at home and abroad, and can greatly reduce the particle spectrum range of the droplets. Penetrates the canopy of fruit trees, and can greatly increase the sap penetration rate of leaves.

Description

technical field [0001] The invention belongs to the field of agricultural medicine equipment, and in particular relates to a self-propelled air-driven orchard sprayer. Background technique [0002] Through a large number of observations on the process of pesticide application in orchards in various places and research on domestic and imported medical equipment, the root of the problem is that the medical equipment is not professional enough and not dedicated enough. Just as the experts say, "one device can control all kinds of crops with one hundred drugs", it is unscientific and cannot keep up with the requirements of the times. As early as 30 years ago, from the replacement of artificial knapsack and push-pull sprayers to the adjustable spray gun spray based on plunger pumps, semi-mechanized progress has been achieved. Until now, plunger pumps are still used for large-capacity spraying Washing method is used to apply pesticides to orchards. The utilization rate of pestici...

AI Technical Summary

Problems solved by technology

[0004] (1) Waste of water and medicine, uneven spraying, impermeable spraying, low liquid penetration rate, high production cost, low mortality rate of pests and diseases, unsatisfactory control effect, short interval between spraying and many times of spraying

The loss rate of fruit due to pests and diseases is high, and the pesticide residues seriously exceed the standard

[0005] (2) Worrying, laborious, and labor-intensive

Pesticide spraying of fruit trees has become the biggest labor pain for fruit farmers in my country. The work efficiency is low and the operation cycle is long. It cannot adapt to the occurrence of disease and insect pests in my country's forestry and fruit industry. It is difficult to realize the unified prevention and control of forestry and fruit industry.

[0006] (3) The wind pressure of the axial flow fan is small, the spray air flow is mostly in a fixed direction, and the air flow of the liquid medicine is sprayed in a straight water flow. The liquid medicine cannot penetrate the canopy of the fruit tree, and the liquid penetration rate of the leaves is not good.

[0007] (4) The plunger pump uses a hand-held spray gun to spray, which is unstable and unreliable

Spraying with fine mist at close range has no penetrating power, and the canopy cannot be sprayed through. Spraying with columnar mist at a long distance costs water and medicine.

[0008] (5) The wind blowing misting machine cannot evenly spray the front and back of the leaves in the center of the canopy

[0009] Through the above five aspects, we can see the current status of chemical control in my country's forestry and fruit industry: troublesome, laborious, costly, and unsatisfactory control effects, resulting in low fruit quality, low yield, low benefit, excessive pesticide residues, and serious environmental pollution
