Abstract

The utility model relates to a shoe-shaped pump sprayer. The upper shell body (30) of a shoe-shaped pump (1) of the utility model forms an upper concave shape which is suitable for making a human body sole sheathed in the shoe-shaped pump, and a lower shell body (7) is provided with a hard bottom (23) and an elastic soft pump chamber (31). An enclosed space is arranged between the upper and the lower shell bodies of the pump chamber, and the pump chamber (31) is communicated with a valve cavity (23) of a valve body (2) through a shoe-shaped pump tube (16). The utility model converts the gravity and the energy of human body in walking into the spraying power of the sprayer, so the pressure of the pump chamber constantly is from 2 kg/cm < 2 > to 3 kg/cm < 2 > and completely adapt the spray work requirement. The sprayed mist is evenly, and the utility model can be sprayed through double rods and double hands. So the work efficiency is enhanced, and the labor strength is lightened. The utility model is the renewal product of the existing knapsack sprayer, and can be widely used for the technical fields of the fertilizer application, the spray medicine and the irrigation.

Description

The footwear pump sprayer

The utility model relates to farm machinery, specifically is meant a kind of sprayer.

Knapsack sprayer is the rural area spray medicine indispensable small-sized machine that applies fertilizer, and still is extensive use of in the rural area at present.This sprayer needs pressurization on the other hand, takes spray boom to work on the other hand, and both hands are not had leisure.The spraying coverage rate is narrow, scatters evenly inadequately, and labour intensity is big, and efficient is low.

The purpose of this utility model provide a kind of with the human body body weight be converted into spraying power, can improve the footwear pump sprayer of executing the spray quality, improving work efficiency, reduce labor intensity.

Described footwear pump sprayer is by the air pressure bag, spray tank, and valve, pump, shower nozzle, spray boom each several part are formed, and it is characterized in that: described pump is a kind of shoe-shaped pump, and the upper shell (30) of footwear pump (1) is and is suitable for the last spill that the human body sole is inserted in; Lower house (17) has a hard end (23), whippy soft pump chamber (31); This pump chamber is the confined space between the last lower house; Footwear pump line (16) links the valve pocket (29) of pump chamber (31) with valve body (2).Valve is that a two-way bilateral is changed the liquid valve, and there is a valve pocket (29) in valve body (2) central authorities, and valve pocket has two chambers, and is middle by a duct UNICOM; One chamber is through air pressure packet interface (26) and air pressure bag (4) UNICOM, and another chamber is by input duct (32) and spray tank (3) UNICOM; With in the chamber of spray tank UNICOM a mobilizable logical spray tank valve piece (24) is housed, press bag valve piece (25) with a mobilizable ventilation is housed in the chamber of air pressure bag UNICOM, in two chambers perpendicular to all be fixed with on place, the valve piece plane chamber wall can be by liquid cross fluid column (28).Each two of footwear pump (1) and valve bodies (2), the left-right symmetry configuration.A bottom filtering frame (5) is equipped with in the bottom of spray tank (3), and bottom screen pack (10) is housed on the filtering frame; Feed liquor filtering frame (8) is equipped with at the top, and feed liquor screen pack (11) is housed on (8).The indoor bottom of pump chamber (31) is pushed up (5) once, following shrinkage joint (21); There is a circle sealing strip (22) at the top and shrinkage joint on (20) is arranged; Last lower house is chimeric and form the sealing pump chamber.

The people is in when walking, and the carrying gravity of pin reaches about 50Kg, and required time capacity of footwear pump pump chamber be by human body 40-60Kg, the every Cm of pump chamber ²Pressure reaches 2-3Kg, and enough operation is required.Because people's leg has very strong endurance, be easy to form persistent joint during operation and gather motion, make the soup maintenance constant compression force in the air pressure bag, so atomization quality is even, the deinsectization efficiency height.The work of two footwear pump impeller stream, the punching press amount is big, has replaced manual punching press program, and therefore union purchase system with the hands is for condition has been created in the multiplication of operation work efficiency.The human body weight that 60Kg is above, pump chamber pressure is big, so spray amount is big and fine and closely woven, for carrying out sharp work, improves deinsectization rate and has created condition with the consumption that reduces agricultural chemicals.Because the footwear pump has been born the punching press program of soup, with the hands the operation of flexibility ground is the dual-purpose condition of having created of a device.

Among the figure: (1)-footwear pump, (2)-valve body, (3)-spray tank, (4)-and the air pressure bag, (5)-bottom filtering frame, (6)-separatory tube head, (7)-and the soup case lid, (8)-feed liquor filtering frame, (9)-valve body hold-doun nut, (10) bottom screen pack, (11) feed liquor screen pack, (12)-junction block, (13)-and left side work feed pipe, (14)-left footwear pump line, (15)-right work feed pipe, (16)-and right footwear pump line, (17)-lower house, (18)-with holes, (19)-return back to top (20)-upward shrinkage joint, (21)-following shrinkage joint, (22)-sealing strip, (23)-and the hard end, (24)-Tong spray tank valve body, bag valve piece is pressed in (25)-ventilation, (26)-the air pressure packet interface, (27)-and caging bolt, (28) cross fluid column, (29) valve pocket, (30)-and upper shell, (31)-pump chamber, (32)-input duct.

Each fixes a footwear pump at the position of centre of gravity of pin, and upper shell is made of plastics, and lower house is made by rubber, in be provided with the pump chamber of certain space, link to each other with the valve body of spray tank through footwear pump line (16).Human body walking is stepped on the pump housing, and lower house shrinks, the liquid pressurized in the pump chamber, ventilation presses the valve piece of bag to open automatically, the valve piece of logical spray tank is closed automatically, and soup is pressed into the air pressure bag, when sole is mentioned, lower house stretches reduction, pump chamber produces vacuum pressure, and valve body is closed automatically towards the valve piece of air pressure bag, and the valve piece of logical spray tank is drawn back, soup is sucked into pump chamber, and reciprocating motion makes the soup that leads to spray boom mist head in the air pressure bag keep the pressure that sets and sprays like this; Thereby reach the operation purpose.
