Manual integrated pesticide spraying device with adjustable range

Abstract

The invention discloses a manual integrated pesticide spraying device with an adjustable range. The pesticide spraying device comprises a first base, a second base and a sector gear, wherein a screw is rotationally mounted on the first base; two swivel nuts are in symmetrical threaded connection with the left and right sides of the screw; two movable rods are symmetrically hinged to the left and right sides of the bottom of the second base; the other ends of the movable rods are hinged with the two swivel nuts; two brackets are symmetrically and fixedly mounted on the left and right sides of the second base; a top plate is fixedly mounted on the upper side of the bracket; the sector gear is rotationally mounted on the top plate by virtue of a second rotating shaft; a square frame is mounted at a position, which is positioned on the outer side of the sector gear, of the top plate in a sliding manner; two gears are symmetrically and rotationally mounted at positions, which are positionedon the front and rear sides of the square frame, of the top plate; a spray head is fixedly mounted on one side, which is far away from the square frame, of the gears. According to the device disclosed by the invention, the pesticide spraying range is accurate, and the pesticides are uniformly sprayed, so that the utilization rate of the pesticides is improved.

Description

technical field [0001] The invention relates to the technical field of pesticide spraying, in particular to a manual-automatic integrated pesticide spraying device with an adjustable range. Background technique [0002] Pesticides are used to kill insects, fungi, and other organisms that harm crop growth. The earliest pesticides used were DDT, BCH, etc., which can eliminate pests in large numbers. However, they have good stability, can exist in the environment for a long time, and accumulate continuously in animals, plants and humans, so they are eliminated. Later, organophosphorus pesticides, such as dichlorvos, were used instead of the original pesticides. Because they are too toxic, they are very harmful to humans and animals. In recent years, a group of high-efficiency and low-toxic pesticides have appeared, which are specific, that is, hormone pesticides. Pesticides have both advantages and disadvantages. They are good for plants, but eating them by mistake will cau...

Problems solved by technology

Pesticides have both advantages and disadvantages. They are good for plants, but eating them by mistake will cause safety hazards. I hope that the majority of pesticide users should be careful

[0003] Pesticide spraying is mostly carried out by manual hand-held spraying devices. The spraying range of this spraying method is extremely limited, and the spraying position needs to be constantly moved and changed. Moreover, spraying with hand-held spraying devices increases the labor intensity of farmers; although automatic spraying devices reduce the The labor intensity of farmers, but it is often difficult to change the spraying range, the spraying position is not accurate, and the spraying is uneven, which affects the spraying effect
