High-ground-clearance unmanned intelligent caterpillar sprayer and control method

Abstract

The invention discloses a high-ground-clearance unmanned intelligent caterpillar sprayer and a control method. Sprayer traveling equipment consists of two caterpillar-type traveling mechanisms with hub motor drivers; the caterpillar-type traveling mechanisms at both sides are connected by a fixed rod, sprayer lifting mechanisms are arranged at the top ends of the caterpillar-type traveling mechanisms at both the sides, and a spraying mechanism comprises drug mixing apparatus and spray rod devices; a trapezoid bracket assembly is assembled inside each caterpillar-type traveling mechanism; both the drug mixing apparatus and control devices are arranged inside the trapezoid bracket assemblies at both sides, and the spray rod devices are arranged on the sprayer lifting mechanisms and are connected with the drug mixing apparatus and move up and down along with traction of the sprayer lifting mechanisms; the control devices are respectively connected with a hub motor, the sprayer lifting mechanisms and the spraying mechanism. According to the high-ground-clearance unmanned intelligent caterpillar sprayer disclosed by the invention, wide spray rods can be simultaneously regulated up and down, so that the spraying requirements of various crops in different growth periods can be met; meanwhile, due to adoption of a remote control mode, the high-ground-clearance unmanned intelligent caterpillar sprayer does not need to be driven by a person, so that a load is reduced, and the automation level is improved.

Description

technical field [0001] The invention relates to a spraying machine, in particular to a high ground clearance unmanned intelligent crawler sprayer and a control method. Background technique [0002] my country is a large agricultural country, and the level of crop protection and fertilization operations directly affects the yield of crops. At present, the level of agricultural mechanization and automation in my country is still relatively low, and there is a lack of equipment for efficient pesticide application in the field. At the same time, for crops with complex spraying topography (such as rice and high-stalk crops, etc.), conventional machinery cannot go to the field, so most of them rely on manpower or spraying. The combination of man and machine leads to problems such as low efficiency, high labor intensity, and poor scale effect. The patent application number is CN201520140029.X.

Problems solved by technology

At present, the level of agricultural mechanization and automation in my country is still relatively low, and there is a lack of equipment for efficient pesticide application in the field. At the same time, for crops with complex spraying topography (such as rice and high-stalk crops, etc.), conventional machinery cannot go to the field, so most of them rely on manpower or spraying. The combination of man and machine leads to problems such as low efficiency, high labor intensity, and poor scale effect

The patent application number is CN201520140029.X. The patent crawler self-propelled air-supply sprayer adopts the traditional crawler structure, which has certain adaptability to complex terrain, but the passability is not good, and the spraying range is limited, which cannot meet the spraying requirements of high-stalk crops in the field.

The patent application number is CN201310288169.7. A tractor walking device adopts a triangular crawler structure, which has a certain adaptability to complex terrain, but there are still problems such as the center of gravity of the device is too high and the passability cannot adapt to high-stalk crops when used in agricultural applications.
