Mounting structure for attitude instrument of pesticide spraying unmanned aerial vehicle

Abstract

The invention discloses a mounting structure for an attitude instrument of a pesticide spraying unmanned aerial vehicle (UAV). The mounting structure for the attitude instrument of the pesticide spraying UAV comprises a main UAV cabin and the attitude instrument, wherein a partition plate is arranged in the main UAV cabin; a position-fixing plate is arranged at the bottom of the attitude instrument; the position-fixing plate is rectangular and parallel to the partition plate; the parts, near the four corners, of the bottom of the position-fixing plate are supported on the partition plate by shock absorbers; the shock absorbers comprise upper guide cylinders, lower guide cylinders and springs; the top ends of the upper guide cylinders are fixed to the position-fixing plate; the upper ends of the lower guide cylinders are sleeved on the lower ends of the upper guide cylinders; the lower guide cylinders are in sliding cooperation with the upper guide cylinders; the lower ends of the lowerguide cylinders are fixed to the partition plate; each spring is arranged in the enclosed space formed by the corresponding upper guide cylinder and the corresponding lower guide cylinder; a gap is arranged between each spring and the inner side wall of the corresponding lower guide cylinder; the upper end of each spring abuts against the inner top wall of the corresponding upper guide cylinder;and the lower end of each spring abuts against the inner bottom wall of the corresponding lower guide cylinder. The mounting structure for the attitude instrument of the pesticide spraying UAV supports the attitude instrument by virtue of the four shock absorbers distributed in a rectangular manner, so as to not only ensure the firmness of the mounting of the attitude instrument, but also effectively reduce the influence of flying vibration on the attitude instrument, thereby ensuring the reliability and long service life of the attitude instrument.

Description

technical field [0001] The invention belongs to the technical field of agricultural machinery, and in particular relates to an attitude meter installation structure on a pesticide spraying machine. Background technique [0002] At present, the UAV that sprays pesticides automatically generally includes a main engine cabin, a cantilever and a power cabin, and the opening on the top of the main engine cabin is sealed by the main engine cabin cover. The attitude indicator is an important instrument on the unmanned pesticide spraying machine, which shows the attitude of the unmanned pesticide spraying machine relative to the horizon. Through the attitude indicator, the operator on the ground can judge the attitude of the pesticide unmanned sprayer as being left-right, upward or downward. The existing attitude indicator is usually installed in the main engine compartment by a bracket made separately, and the installation method of the attitude indicator is a hard connection. Be...

Problems solved by technology

Because the unmanned pesticide spraying machine will be affected by wind resistance, airflow and other factors during the flight, it will inevitably produce vibration and turbulence, and this vibration and turbulence will be directly transmitted to
