Description

Upright aerial work vehicle with pest control function {Pest control function with high place working vehicles}

The present invention relates to an upright aerial work platform with a pest control function, and more specifically, to an upright aerial work platform with a pest control function, which allows the height of the workbench to be adjusted by raising and lowering the workbench on which the worker rides upward for pest control work. It's about aerial work trucks.

In general, a variety of vehicles are known as pest control vehicles that automatically spray pesticides to prevent various pests and diseases on fruit trees when cultivating orchards.

For example, a representative example is a pest control vehicle called an ESESS vehicle, which is equipped with a driver's seat at the front with an opening on one side to facilitate the driver's boarding, and is equipped with a pump, nozzle, and blower at the rear.

In these pest control vehicles, when the worker in the driver's seat at the front adjusts the pressure of the nozzle, pesticide is sprayed through the nozzle at an appropriate pressure by the pressure adjusted by the pump at the rear, and the sprayed pesticide is adjusted to the blowing pressure of the blower. As it spreads widely, widespread spraying takes place.

Such a conventional pest control vehicle has been proposed in Republic of Korea Patent No. 10-1201952 (hereinafter referred to as 'prior art literature').

The conventional pest control vehicle disclosed in the prior art literature is provided on the upper side of the driver's seat of the pest control vehicle, which has an opening on one side to facilitate the driver's boarding, and has a micro window in the vertical direction so that the see-through window can be opened and closed on both sides. A first side that is integrally connected to the rear and the front and rear sides and is provided with a vertically transparent glass window, a second side that is provided in the direction of the opening of the driver's seat and is located opposite to the first side, and A detachable cabin of a pest control vehicle consisting of an upper surface provided in a horizontal direction on the upper side of the rear, an inclined surface integrally connected with the upper surface, and equipped with a glass window to allow viewing the front, and insulation material provided in the remaining portion except for the glass window. In this case, the cabin is attached to the upper horizontal direction of the second side and the vertical direction on both sides by adhesive means made of Velcro tape, and the lower end cut in the vertical direction is made of transparent vinyl suspended to the bottom of the opening of the pest control vehicle. A control curtain made of; It includes a mounting means provided with a magnet and a buffer member on the front, rear, and lower first side so that it can be mounted on the pest control vehicle.

However, in the case of the conventional pest control vehicle disclosed in the prior art literature, when actually carrying out quarantine and pest control work, there are frequent cases where the control part of the pest control vehicle does not reach the crops depending on the location of the vehicle and the slope of the rear ground. The pest control vehicle has the disadvantage that pest control work is impossible in this case.

As a result, despite the existence of a control unit that sprays chemicals on crops by rotating a large blowing fan, in the above situation, workers connect a separate hose to the chemical tank and control the plants through a manual nozzle. However, this is also true in practice. Considering that the ground environment of orchards etc. is irregularly sloping, this method has the disadvantage of significantly lowering work efficiency.

In particular, when the height of trees such as tropical fruits is high, there are limits to the ability of workers to manually spray and spray chemicals, which has the disadvantage of preventing proper control.
