The utility model relates to an
insect repellent spraying device for
plant protection. The
insect repellent spraying device comprises a spraying
machine box, the feeding port is fixedly installed on the spraying
machine box, a conveying
pipe is inserted into one side of the spraying
machine box, a spraying rod is arranged on one side of the spraying machine box, and the other end of the conveying
pipe is fixedly installed on the spraying rod; and the adjusting
assembly is arranged on one side of the spraying rod, and the adjusting
assembly comprises a spraying box, a first spraying hole, a second spraying hole, an adjusting plate, a sliding block and a traction groove. Omnibearing spraying of plants can be achieved through first spraying holes and second spraying holes formed in the spraying box, the working efficiency can also be greatly improved, an adjusting plate is pressed, a sliding block moves downwards along a traction groove, and when a clamping block is clamped in a clamping groove, the two sides of the adjusting plate shield the first spraying holes formed in the two sides of the spraying box, so that the spraying efficiency is improved. The
insect repellent can only be sprayed out downwards through the second spraying holes, the spraying direction of the second spraying holes cannot be affected in time when the
insect repellent encounters strong wind, and therefore plants can be sprayed more evenly.
