Embodiment 1

[0038] Embodiment 1: as figure 1 As shown, a knapsack sprayer includes a base 1, a liquid storage cylinder 2 disposed on the base 1, a spray tube 3 disposed on the liquid storage cylinder 2, a pressure pump 4, and a linkage mechanism 5 for driving the pressure pump 4 to work .

[0039] Such as figure 1 As shown, the link mechanism 5 includes a connecting rod 51 and a rocker 52 hinged to the outer wall of the base 1 . The pressure pump 4 is provided with a piston rod 41 .

[0040] When using the above-mentioned sprayer, inject the pesticide and clear water into the liquid storage cylinder 2, and stir the pesticide and clear water. Then, by controlling the rocker 52 to reciprocate up and down, the rocker 52 is used to drive the connecting rod 51 and the piston rod 41 to move synchronously, so as to realize the stable control of the operation of the pressure pump 4 and pressurize the inside of the liquid storage cylinder 2 . Finally, the medicinal liquid is sprayed along the s...

Embodiment 2

[0059] Embodiment 2: as figure 1 , Figure 5 As shown, the difference from Embodiment 1 is that: the base 1 is provided with a concave cavity 12 , and the driving mechanism 6 includes a driving rod 66 horizontally arranged in the concave cavity 12 . Both ends of the driving rod 66 are rotatably connected to the two inner walls of the cavity 12 , and one end of the driving rod 66 is fixed to the rocker 52 .

[0060] Such as Figure 5 As shown, one end of each rotating shaft 21 located in the concave cavity 12 is horizontally provided with a first bevel toothed disc 67, and a pair of second cones respectively meshing with a pair of first bevel toothed discs 67 are vertically provided on the driving rod 66. toothed disc 68 , and a pair of second bevel toothed discs 68 are distributed on both sides of the pair of first bevel toothed discs 67 .

[0061] When the rocker 52 swings back and forth, the rocker 52 controls the drive rod 66 and the pair of second bevel gears 68 to rota...

Abstract

The invention discloses a knapsack sprayer, and relates to the field of agricultural tools. The knapsack sprayer comprises a base, a liquid storage barrel, a spray pipe, a pressure pump and a connecting rod mechanism, wherein the liquid storage barrel is arranged on the base; the spray pipe and the pressure pump are arranged on the liquid storage barrel; the connecting rod mechanism is used for driving the pressure pump to work; a pair of rotating shafts is vertically arranged on the bottom wall of the liquid storage barrel; the rotating shafts are rotatably connected to the bottom wall of theliquid storage barrel; stirring wheels are arranged on the rotating shafts; and a driving mechanism used for driving the rotating shafts to rotate is arranged in the base. The knapsack sprayer has the following advantages and effects that by arranging the stirring wheel, real-time stirring of pesticide liquid is achieved while the pesticide liquid is sprayed, pesticide and clear water are fully mixed, and the precipitation phenomenon of the pesticide is avoided, so that the insecticidal effect of the pesticide liquid is guaranteed.

Description

technical field [0001] The invention relates to the field of agricultural tools, in particular to a knapsack sprayer. Background technique [0002] Sprayer is the abbreviation of spraying equipment. It is an indispensable and important agricultural tool for the prevention and control of diseases and insect pests. , nozzles and other components. [0003] Chinese patent CN205161672U discloses a knapsack sprayer, which includes a liquid storage cylinder, a nozzle tube and a pressure pump located on the liquid storage cylinder, and a linkage mechanism that drives the pressure pump to work. The rocker on the cylinder is provided with a piston rod on the pressure pump, and the two ends of the connecting rod are respectively hinged on the rocker and the piston rod. [0004] When the above sprayer is in use, a pressure pump is used to pressurize the inside of the liquid storage cylinder, so that the liquid medicine is sprayed out along the spray pipe. However, during the spraying...
