Description

Foot-operated sprayer

The utility model relates to a kind of agricultural machinery, especially sprayer.

The sprayer of people's use at present is armrest, machinery or chemical addition agent reaction pressurization and generation hydrojet effect, has shortcomings such as amount of operation labor is big, input cost is high, vibration is big.

The purpose of this utility model provide a kind of simple in structure, easy to use, utilize human body self gravity, in the people walks operation process, gravity be converted into hydrojet pressure and produce the foot-operated sprayer of hydrojet effect.

For achieving the above object, the utility model is made up of three parts: hold liquid bucket, liquid-jet device, foot-operated pressue device, foot pedal apparatus is by being connected with liquid-jet device by the pipeline that holds the liquid bucket, it is identical with the device of existing hand pressure sprayer with liquid-jet device to hold the liquid bucket, changes the hand parts and is foot-operated pressue device.Foot-operated pressue device constitutes by adding pneumatic tube, piston, connecting rod, return pipe, pedal.Adding pneumatic tube has 2, between be communicated with by the fixed piston connecting rod, connecting rod is the solid steel bolt of spill, connects piston with nut; Adding the pneumatic tube upper end has fixing pipeline to connect, and is provided with hoodle in the pipeline and prevents that liquid from flowing into the lower end from adding the pneumatic tube upper end; The fixing connection of return pipe adding the side of pneumatic tube, can make the anti-upper end that flows into of water pressurization of lower end; Pedal is " recessed " shape, the upper end with retainer ring with add pneumatic tube and be connected, move up and down with pedal in order to fixing inflator, the bottom of pedal is connected with connecting rod with loose collar, foot pedal apparatus is close to the position that adds pneumatic tube at connecting rod and is provided with the bullet ring.

During work, respectively at the instep portion and the bound feet portion rope fixing feet pedal of footwear or boots.In the process of walking about, the elastic resistance that gravity will overcome spring descends inflator, and liquid is squeezed into air chamber and hydrojet, when pressurization stops, spring absorbs water by elastic recovery of itself and the liquid height official post piston decline of holding in the liquid bucket, thereby enters next working cycles.

The utility model has the advantages that: solved manual sprayer because of operation inconvenience due to the hand pressurization, shortcoming such as the amount of labour is big, characteristics such as it is low to have an input cost, simple in structure, a pressue device that only needs to change manual sprayer can reach goal of the invention.Most importantly careless intensified pressure, if about two pin use simultaneously, pressure is multiplied, solved difficult problems such as high-altitude remote job.The design return pipe has solved seepy question, and designing material has solved an amphibious difficult problem, can pull down fragile parts such as spring when a period of time does not use respectively, is easy to maintenance, be applicable to the spray liquid under the various conditions, be particularly useful for spraying pesticides such as orchard, nonirrigated farmland.

Below in conjunction with the drawings and specific embodiments the utility model is described in further detail.

Fig. 1 is a schematic diagram of the present utility model.

As shown in the figure, the utility model comprises and holds liquid bucket 1, connects the liquid-jet device of atomizer and by adding the foot-operated pressue device that pneumatic tube 7, piston 13, connecting rod 12, return pipe 6, pedal 9 constitute, foot pedal apparatus is connected with liquid-jet device by plastic tube 3, the rubber tube 5 that holds the liquid bucket by valve 2, plastic tube 3, balancing gate pit 4 with at A.Adding pneumatic tube has 2, between be communicated with by fixed piston 13, connecting rod 12, is connected by nut between connecting rod and the piston, adding the pneumatic tube upper end has 5 connections of fixing rubber tube; The fixing connection of return pipe adding the side of pneumatic tube, pedal 9 upper ends with retainer ring 10 with add pneumatic tube 7 and be connected, the bottom usefulness loose collar 11 of pedal is connected with connecting rod 9, foot pedal apparatus is close to the position that adds pneumatic tube at connecting rod and is provided with bullet ring 8.

Claims (3)
