Then spraying all fruit trees in the radius by taking the branch pipe A19 or the branch pipe B25 as the center of a circle and taking the middle hose A20 or the middle hose B25 as the radius; during spraying, liquid medicine is pumped from a liquid medicine source through the liquid pumping power device 16 from a liquid medicine source, then the pre-buried pipe A18, the branch pipe A19 with the opened valve 28, the hose A20 communicated with the branch pipe A19 and the multi-way pipeline A21 are fastened and enter the tail end hoses A22, and finally the liquid medicine is pumped into the first fluid inlet of the nozzle 2; meanwhile, pressure gas is sent into a pre-buried pipe B23, a branch pipe B24 with an opened valve 28, a hose B25 communicated with the branch pipe B24 and a multi-channel pipe B26 through a pressure gas supply device 17, enters each tail end hose B27 and finally enters a second fluid inlet of the nozzle 2; the pressurized gas and pressurized liquid are then mixed in the interior of the nozzle 2 and are ejected through the ejection end of the nozzle 2.

After spraying the liquid medicine on the fruit forest in the radius, closing the valve 28, detaching the middle hose A20 from the branch pipe A19, and connecting the middle hose A20 with the next branch pipe A19; the middle hose B25 is detached from the branch pipe B24 and connected to the next branch pipe B25, and then the next tablet area is sprayed with the liquid medicine.

In the invention, the power sources of gas and liquid are arranged in the machine room, thereby greatly reducing the gravity borne by workers. Compared with the existing knapsack sprayer, the knapsack weight of the knapsack sprayer is reduced from 20-40 kg originally to 8kg, so that the labor intensity of workers is greatly reduced; simultaneously, need not repeatedly to add liquid medicine, directly through each branch pipe carry on the access of gas, liquid can, spout medicine efficient, to the afforestation orchard, alone this equipment, can spray the orchard more than 40 mu a day, compared with current spray by water lever, efficiency has promoted about ten times, has greatly reduced workman intensity of labour, has reduced the cost of labor, the fruit tree planting of being convenient for.

The quick pipeline connecting plug is convenient for connecting or separating each hose with the corresponding branch pipe more quickly and conveniently.

Example 5

This embodiment further optimizes and explains the present solution on the basis of embodiment 4.

As shown in fig. 3 and 4, the spraying system further includes a switch assembly including a positioning plate 29 and two rotary valves 30 both fixed to the positioning plate 29, wherein an input end and an output end of one of the rotary valves 30 are connected to the intermediate hose a20 and the multi-way pipe a21, respectively, and an input end and an output end of the other rotary valve 30 are connected to the intermediate hose B25 and the multi-way pipe B26, respectively. The rotary valve 20 includes, but is not limited to, a ball valve.

The valve rods 31 of the two rotary valves are opposite to each other, the opening and closing rotation directions of the valve rods 31 are the same, a synchronous sleeve 32 coaxial with the valve rods 31 is arranged between the valve rods 31, and two ends of the synchronous sleeve 32 are respectively sleeved on one valve rod 31.

The positioning plate 29 is preferably connected to one side of the carrier for supporting the bracket 1 by an L-shaped bent rod; when the liquid medicine needs to be sprayed, a worker manually rotates the driving handle of one rotary valve 30, and then the other rotary valve 30 can be opened through the synchronous sleeve 32, so that the convenience in use of the liquid medicine spraying device is improved.
