Bumping-prevention aerial spraying medical kit structure

Abstract

The invention relates to the technical field of aerial pesticide spraying, in particular to a bumping-prevention aerial spraying medical kit structure which is characterized in that one or two sliding rods (3) are vertically and rigidly fixed at the bottom of a medical kit (1), a compression wave floating plate (2) is arranged in the medical kit (1), one or two sliding holes (9) corresponding to the sliding rods (3) in position are arranged on the compression wave floating plate (2), tubular sliding sleeves (4) are arranged above or below or at the position above and below the sliding holes (9), the internal diameter of the sliding sleeves (4) and the hole diameter of the sliding holes (9) are the same and are respectively equal to the value obtained by adding the diameter of the sliding rods (3) to the mutual sliding gap; or three sliding rods (3) not in the straight-line position are vertically and rigidly fixed at the bottom of the medical kit (1), the compression wave floating plate (2) is arranged in the medical kit (1), three sliding holes (9) corresponding to the sliding rods (3) in position are arranged on the compression wave floating plate (2), the sliding holes (9) on the compression wave floating plate (2) are sleeved on the corresponding sliding rods (3), and the hole diameter of the sliding rods (3) is equal to the value obtained by adding the diameter of the sliding rods (3) to the mutual sliding gap. The bumping-prevention aerial spraying medical kit structure ensures that gravity center shifting and shaking are avoided during plane flying, and plane safety is greatly improved.

Description

technical field [0001] The invention relates to the technical field of aerial pesticide spraying, in particular to an improved structure of an aerial spraying medicine box. Background technique [0002] Paddy fields account for about 34% of the pest and weed control area in my country over the years, accounting for one-third of the total control amount. For a long time, the prevention and control of rice pests and weeds has mainly relied on manual sprayers and knapsack motorized sprayers. Not only is the labor intensity high, the work quality is poor, and the work efficiency is low, it is difficult to meet the requirements of rapid and effective control of major outbreaks of diseases, insect pests and weeds. It has also become the main technical bottleneck restricting the realization of the goal of rice mechanization. Aerial spraying is an effective means to solve the special field operation conditions of paddy fields, but conventional fixed-wing aircraft spraying technolog...

AI Technical Summary

Problems solved by technology

[0003] An indispensable and important component in aviation spraying technology is the airborne medicine box, in which the pesticide solution for spraying is injected. , there will be rising and falling, sudden airflow changes, etc., which will inevitably cause fluctuations in the medicine box, and the liquid medicine in the medicine box will shake, sometimes when the vibration of the medicine liquid is close to the inherent vibration frequency of the aircraft itself. The amplitude of vibration will be very large, which will affect the stability of aircraft driving, affect the quality of spraying, and in serious cases, it will affect the safety of aircraft flight and cause destructive accidents

The method generally adopted at present is to place a floating plate on the liquid medicine surface of the medicine box to reduce some splashed liquid medicine and reduce the oscillation fluctuation of some liquid medicine, but practice proves that the effect is not ideal, and the floating plate floating on the medicine surface Without support and lead climbing, it will still shake with the shaking of the liquid medicine, the vibration reduction effect is not obvious, and there are still potential safety hazards

[0004] There is an improvement plan to add springs or other suction mechanisms on the floating plate. Since the floating plate will rise and fall with the rise and fall of the liquid level, the height will change, and the elastic force of the spring and other forces will also change when the distance and height change. Therefore, It is impossible to guarantee that the liquid level is at any height, and the pressure force and stability maintenance force of the floating plate on the liquid level are constant, so it is difficult to realize the effect of such an improved mechanism
