Portable Spraying Device

Abstract

The invention discloses a portable spraying device, which comprises a paint bucket (1), a strap (2), a tensioning mechanism A (9), a fixing seat (17), a tensioning mechanism B (18), and a paint bucket (1). Two straps (2) are fixed, and the paint bucket (1) feed port is connected with a bucket cover (8), which is characterized in that the tensioning mechanism A (9) and tensioning mechanism B (18) are symmetrically and flexibly connected to the fixed seat (17) On both sides, spraying mechanism A (12) and spraying mechanism B (13) are fixedly installed on tensioning mechanism A (9), and spraying mechanism C (14) and spraying mechanism D ( 15), the spraying mechanism includes: an arc-shaped spraying pipe (29), a plurality of runners (30) installed uniformly connected to the spraying pipe (29), and a brush pipe ( 31). The invention has the characteristics of rolling spraying, low labor intensity and uniform spraying.

Description

technical field [0001] The invention belongs to the technical field of agricultural machinery, and in particular relates to a portable spraying device. Background technique [0002] The main objects of tree whitening are roads, farmland shelterbelts, urban areas, campus green forests, etc. At present, the work of tree whitening is done manually or with large mechanical devices. Manual whitening is low in efficiency and high in work intensity , in order to evenly coat all sides of the tree with lime slurry, it takes a lot of manpower, material and financial resources to complete this work. The whitening of large mechanical devices needs to be carried by vehicles or manually pushed by whitening machines, which is not easy to handle. Complex trees. [0003] It is known that the Chinese patent publication number is CN201620683968.3, and the "trunk whitener" was disclosed on January 11, 2017. Although it has solved the inconvenience of spraying trees for terrain review, the comp...

[0002] The main objects of tree whitening are roads, farmland shelterbelts, urban areas, campus green forests, etc. At present, the work of tree whitening is done manually or with large mechanical devices. Manual whitening is low in efficiency and high in work intensity , in order to evenly coat all sides of the tree with lime slurry, it takes a lot of manpower, material and financial resources to complete this work. The whitening of large mechanical devices needs to be carried by vehicles or manually pushed by whitening machines, which is not easy to handle. complex trees

[0003] It is known that the Chinese patent publication number is CN201620683968.3, and the "trunk whitener" was disclosed on January 11, 2017. Although it has solved the inconvenience of spraying trees for terrain review, the compressor is manually operated with the left hand. The viscosity of the liquid is high, and the labor intensity of the left-hand compressor for a long time will easily cause arm pain. At the same time, the right hand operates the spray head at the end of the liquid pipe to slide on the sprayed trees for whitening work. If you use too much force, the spray head will cling to the trees. , causing the spray head to discharge too slowly, resulting in uneven spraying, long-term right-hand sliding operations, and high labor intensity can easily lead to sore arms
