Adapted handhold pesticide spraying device

Abstract

The invention relates to the technical field of agricultural machinery, in particular to an adapted handhold pesticide spraying device. According to the adapted handhold pesticide spraying device disclosed by the invention, a liquid outlet rod can be applied to the surfaces of trunks of different diameters through the haulage of a haulage rope, so that the flow of applying pesticides on trunks byoperating staff can be simplified, liquid pesticides can be sufficiently applied on the trunks without enabling the handhold pesticide spraying device to surround the trunks; the adapted handhold pesticide spraying device has practical significance and popularization value, and favorable expectation economic benefits can be produced. The adapted handhold pesticide spraying device comprises a grabbing handle, a connecting pipe, a handle, a flow limiting device, the liquid outlet rod and the haulage rope, wherein a connecting part is arranged at the tail end of the grabbing handle; the connecting pipe is arranged at the top end of the grabbing handle; the handle is hinged to the grabbing handle; a moving end is movably connected to the tail end of the handle; the flow limiting device is arranged on the grabbing handle; the liquid outlet rod is arranged at the top end of the connecting pipe, and is formed by the hinging of plural liquid outlet pipes which are sequentially connected in a head and tail manner on the same side; and one end of the haulage rope is connected with the top end of the liquid outlet rod, and the other end of the haulage rope is connected with the moving end.

Description

technical field [0001] The invention relates to the technical field of agricultural machinery, in particular to an adaptive handheld spraying device. Background technique [0002] The definition of pesticides in a broad sense refers to the chemical synthesis used to prevent, eliminate or control harmful organisms such as diseases, insects, and grasses that endanger agriculture and forestry, and to regulate, control, and affect plant biological metabolism, growth, and reproduction. Pesticides are a substance or a mixture of several substances and their preparations produced by natural products or applied biotechnology, which can ensure the normal growth of plants and crops. [0003] Because the tree skin is prone to pests and diseases, it is often necessary to apply medicine on the surface of the trunk. Common medicines include trichloromite emulsion, lime sulfur mixture, and Bordeaux mixture. Traditionally, the medicine is applied by manual brushing, which is inefficient and...

[0003] Because the tree skin is prone to pests and diseases, it is often necessary to apply medicine on the surface of the trunk. Common medicines include trichloromite emulsion, lime sulfur mixture, and Bordeaux mixture. Traditionally, the medicine is applied by manual brushing, which is inefficient and time-consuming. It is laborious. At present, manual spraying is mainly used. The operator sprays the trees with a spraying device. Since the bark surface of the trunk is a curved surface, the operator needs to spray the pesticide around the trunk with a handheld spraying device to fully spray the pesticide. Smeared on the trunk, in order to save time and improve work efficiency, some operators often increase the pump pressure, so that the sprayed pesticide can be diffused in the air and can cover a larger trunk area, which will lead to more pesticides. liquid waste, and most pesticides are physiologically toxic, and the diffuse pesticide mist is likely to cause poisoning of operators and pedestrians. If improvements are made on the basis of existing equipment, a spraying device suitable for tree trunks with different diameters will be developed, which will help improve The utilization rate of pesticides and the protection of the health of operators will be of positive significance
