A lifting spray rod device

Abstract

The invention discloses an elevating spray rod device; spraying machine walking equipment comprises two crawler type running gears driven by a wheel hub motor; the crawler type running gears on two sides are connected through a fixed rod; tops of the two crawler type running gears are respectively provided with a spraying machine elevating system; a spray mechanism comprises a drug mixing device and the spray rod; a trapezoid support assembly is assembled in each crawler type running gear; the drug mixing device and a controller are respectively arranged on the inner side of the trapezoid support assembly on two sides; the spray rod is arranged on the spraying machine elevating system and connected with the drug mixing device, and can move up and down along with traction of the spraying machine elevating system; the controller is respectively connected with the wheel hub motor, the spraying machine elevating systems and the spray mechanism; the broad width spray rod of the elevating spray rod device can be up-down adjusted, thus satisfying spraying demands of various crops in different growth periods; in addition, a remote control mode is employed to replace man-driving, thus reducing weight, and improving automation level.

Description

technical field [0001] The present invention relates to a spraying machine, in particular to a spray boom device which can be used for raising and lowering. Background technique [0002] my country is a big agricultural country, and the level of plant protection and fertilization of crops directly affects the output 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 application of pesticides in the field. At the same time, for crops with complex spray application terrain (such as rice and high-stalk crops), conventional machinery cannot be used in the field, so most of them rely on manpower or The combination of man and machine leads to problems such as low efficiency, high labor intensity, and poor scale effect.

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.
