Description
Technical field
The utility model relates to a kind of sprayer, especially a kind of knapsack sprayer.
Background technology
Sprayer utilizes suction effect that liquid medicine or other liquid are become vaporific, is ejected into the utensil on other objects equably, is made up of compressed-air actuated device and tubule, nozzle etc.
Knapsack sprayer is the one of sprayer, and it is widely used in agricultural production, because structure is simple, easy to operate, cheap, dark liking by peasant.But peasants' hand control spray boom, a hand control rocking bar, just cannot vacate hand and do other thing.Laxative of going out such as summer just cannot vacate hand expelling mosquito; Go evening laxative not send out and vacate hand to hand contact electric lighting.
Utility model content
For the deficiency that prior art exists, the purpose of this utility model is to provide a kind of pin to replace hand to control the knapsack sprayer of rocking bar.
For achieving the above object, the utility model provides following technical scheme: a kind of knapsack sprayer, comprise the linkage of liquid storing barrel, compression pump and driving pressure pump work, it is characterized in that: described linkage comprises the clamping device of connecting rod, rocking bar and trapping human's leg, described connecting rod one end is connected on the piston rod of described compression pump, the described connecting rod other end is articulated with one end of rocking bar, the described rocking bar other end is hinged with clamping device, the described rocking bar body of rod has a projection, described projection is articulated with on liquid storing barrel.
By adopting technique scheme, gripping apparatus grips is at the leg of human body, and along with walking about of people, the rocking bar be connected on clamping device also swings thereupon, thus drive link moves up and down, and the compression pump that is connected with connecting rod just can draw the liquid medicine in liquid storing barrel.
The utility model is set to further: described rocking bar shape is V-arrangement, and described projection is arranged in the flex point of V-arrangement rocking bar.
By adopting technique scheme, the rocking bar of this shape meets ergonomics, and clamping device is just in time positioned at by human leg, simultaneously along with people to walk the distance that kinetic energy makes connecting rod move up and down longer, improve the hydraulic pressure rate of climb.
The utility model is set to further: described clamping device comprises Handheld Division and clamping section, and described clamping section comprises the intermediate plate of a pair circular shape, and described Handheld Division is provided with fastening spring.
By adopting technique scheme, the intermediate plate of circular shape follows the leg of people to coincide, and human body sensory is more comfortable.
The utility model is set to further: described intermediate plate is provided with improved mat.
By adopting technique scheme, can effectively prevent clamping device from sliding at leg.
The utility model is set to further: described liquid storing barrel sidewall is provided with observation window, and described observation window is other is provided with scale.
By adopting technique scheme, people can facilitate observed stage by observation window, know that liquid in bucket also has how many, can know liquid proportion amount easily by the scale being arranged on observation window other.
Compared with prior art, the beneficial effects of the utility model are: gripping apparatus grips is at the leg of human body, and along with walking about of people, the rocking bar be connected on clamping device also swings thereupon, thus drive link moves up and down, the compression pump that is connected with connecting rod just can draw the liquid medicine in liquid storing barrel.The rocking bar of V-arrangement shape meets ergonomics, and clamping device is just in time positioned at by human leg, simultaneously along with people to walk the distance that kinetic energy makes connecting rod move up and down longer, improve the hydraulic pressure rate of climb.The intermediate plate of circular shape follows the leg of people to coincide, and human body sensory is more comfortable.Intermediate plate arranges improved mat and can effectively prevent clamping device from sliding at leg.People can facilitate observed stage by observation window, know that liquid in bucket also has how many, can know liquid proportion amount easily by the scale being arranged on observation window other.

Detailed description of the invention
Elaborate below in conjunction with the detailed description of the invention of accompanying drawing to the utility model knapsack sprayer.
A kind of knapsack sprayer, comprise connecting rod 4 mechanism of liquid storing barrel 1, compression pump 2 and driving pressure pump 2 work, described connecting rod 4 mechanism comprises the clamping device 6 of connecting rod 4, rocking bar 5 and trapping human's leg, described connecting rod 4 one end is connected on the piston rod 3 of described compression pump 2, described connecting rod 4 other end is articulated with one end of rocking bar 5, and described rocking bar 5 other end is hinged with clamping device 6, described rocking bar 5 body of rod has a projection, described projection is cylindrical, and described projection is articulated with on liquid storing barrel 1.Described rocking bar 5 shape is V-arrangement, and described projection is arranged in the flex point of V-arrangement rocking bar 5.Described clamping device 6 comprises Handheld Division 6d and clamping section, and described clamping section comprises the intermediate plate 6a of a pair circular shape, and described intermediate plate 6a is provided with improved mat 6c, improved mat 6c is quality of rubber materials, there is intensive kick on surface, and for increasing stiction, described Handheld Division 6d is provided with fastening spring 6b.Described liquid storing barrel 1 sidewall is provided with observation window 7, and described observation window 7 is other is provided with scale 8, the millimeter during least unit of scale 8.
During work, first by braces 9 knapsack sprayer back, again clamping device 6 is clamped in leg, walk about a few step, clamping device 6 drives rocking bar 5 to swing, and the connecting rod 4 hinged with rocking bar 5 moves up and down thereupon, connecting rod 4 piston rod 3 is moved, compression pump 2 just from water suction work in liquid storing barrel 1, can now open the switch of spray boom 10, and spraying just defines.
Along with walking about of people, hydraulic pressure in compression pump 2 rises gradually, when human leg feels that comparison of resistance is large, represent that the pressure in compression pump 2 is very high, water suction is not temporarily needed to increase pressure, now unclamp clamping device 6 by Handheld Division 6d, rotate clamping device 6 and make it not move interference with people's leg, when sensation pressure is inadequate by the time, press from both sides back leg.
By adopting technique scheme, clamping device 6 is clamped in the leg of human body, and along with walking about of people, the rocking bar 5 be connected on clamping device 6 also swings thereupon, thus drive link 4 moves up and down, the compression pump 2 that is connected with connecting rod 4 just can draw the liquid medicine in liquid storing barrel 1.The rocking bar 5 of V-arrangement shape meets ergonomics, and clamping device 6 is just in time positioned at by human leg, simultaneously along with people to walk the distance that kinetic energy makes connecting rod 4 move up and down longer, improve the hydraulic pressure rate of climb.The intermediate plate 6a of circular shape follows the leg of people to coincide, and human body sensory is more comfortable.Intermediate plate 6a arranges improved mat 6c and can effectively prevent clamping device from sliding at leg.People can facilitate observed stage by observation window 7, know that liquid in bucket also has how many, can know liquid proportion amount easily by the scale 8 being arranged on observation window 7 other.
