Liquid pesticide automatic spraying device for farmland machinery

Abstract

The invention belongs to the technical field of agricultural equipment, and particularly relates to an automatic pesticide medicine spraying device for farmland machinery. The device comprises a base,wherein a surface of the base is connected with a first upright post, a second upright post is sleeved in the first upright post, a top end of the second upright post is connected with an air cylinder and a fixed block, the air cylinder is positioned on an outer side of the fixed block, sliding grooves are formed in two sides of the fixed block, and a liquid pesticide conveying pipe shell is movably connected in the fixed block, a bottom end of the liquid pesticide conveying pipe shell is connected with the air cylinder through a rotating shaft, and the air cylinder, the liquid pesticide conveying pipe shell, a second sliding block, the fixing block and a spray head shell are arranged at a top end of the second upright post, the liquid pesticide conveying pipe shell is movably connected in the fixed block and the spray head shell by adjusting the air cylinder, an angle of a spray head is adjusted, spraying treatment on a back surface of crop blade is facilitated, a pesticide receivinggroove is arranged at a bottom end of the spray head shell, and the pesticide is collected into a pesticide collecting bottle through a pesticide collecting pipe, so that pesticide waste is avoided,meanwhile, the pesticide is prevented from dropping to a human body.

Description

technical field [0001] The invention belongs to the technical field of agricultural equipment, and in particular relates to an automatic liquid medicine spraying device for farmland machinery. Background technique [0002] Crop diseases and insect pests are one of the main agricultural disasters in my country. It has the characteristics of many types, great impact, and frequent outbreaks. The scope and severity of its occurrence and severity often cause heavy losses to my country's national economy, especially agricultural production. In the current technology, most of the sprayers are backpack-type, requiring farmers to carry the sprayer on their backs to spray. This method is very labor-intensive, increases labor output during spraying, and is less efficient. The medicine will drop, and it will easily cause damage to the skin when it falls on the human body. At the same time, when spraying pesticides, most of them can only spray on the surface of the leaves of the crops. Man...

[0002] Crop diseases and insect pests are one of the main agricultural disasters in my country. It has the characteristics of many types, great impact, and frequent outbreaks. The scope and severity of its occurrence and severity often cause heavy losses to my country's national economy, especially agricultural production. In the current technology, most of the sprayers are backpack-type, requiring farmers to carry the sprayer on their backs to spray. This method is very labor-intensive, increases labor output during spraying, and is less efficient. The medicine will drop, and it will easily cause damage to the skin when it falls on the human body. At the same time, when spraying pesticides, most of them can only spray on the surface of the leaves of the crops. Many pests will hide on the back of the leaves of the crops, resulting in poor spraying effect and reduced efficiency. At present, it is necessary to optimize and improve the structure of the problems exposed in the spraying process of the sprayer
