Two-degree freedom nozzle angle adjusting device

Abstract

The invention relates to a two-degree freedom nozzle angle adjusting device which comprises a driving assembly I, a driving assembly II, a nozzle assembly and a bracket, wherein the driving assembly I and the bracket are connected with a tiller A through an output shaft I of a steering engine I in an interference fit manner; the driving assembly II and the nozzle assembly are connected with a tiller B through an output shaft II of a steering engine II in an interference fit manner; one end of the bracket is fixedly connected with the driving assembly II through bolts; and the other end is connected with the nozzle assembly through a sliding bearing. According to the device, the two tillers are respectively driven by the two steering engines to realize the spraying angle change of the nozzle in the vertical direction and the horizontal direction, so that the nozzle is enabled to flexibly adjust the spraying angle according to spraying targets and spraying demands.

Description

technical field [0001] The invention relates to an angle adjustment device, in particular to a two-degree-of-freedom nozzle angle adjustment device, which belongs to the field of agricultural and industrial robots. technical background [0002] Sprayer is a commonly used agricultural plant protection machinery, which is widely used in the prevention and control of crop diseases and insect pests, and can also be used for sanitation, epidemic prevention, disinfection and sterilization. With the improvement of agricultural planting level, in order to minimize the pollution and waste caused by pesticides or fertilizers used in agricultural production, it is currently required to accurately dispense liquid pesticides or fertilizers in the process of using them. And according to the different objects of spraying crops, it is necessary to adjust the angle and orientation of spraying. Most of the nozzles of existing sprayers are fixed on the end of the spray rod and do not have the...
