Abstract

The utility model relates to an auxiliary device for an agricultural knapsack sprayer, and the auxiliary device is arranged between the switch and the spraying head of a sprayer. The utility model is provided with a structure for specially storing agricultural chemicals, and clear water instead of liquid medicine mixed well is filled into the bucket of the sprayer. When the utility model is operated and pressurized water flows across the auxiliary device, the liquid medicine in a medicine storing chamber is sucked and spouted after mixed with the clear water via negative pressure formed locally. Owing to the liquid medicine is separated and stored, the poisoning phenomenon of the agricultural chemicals caused by the liquid medicine splashing and leaking on body of the original equipment is reduced thusly, and the security of the user of the sprayer is enhanced.

Description

Medicine doser

The spray insecticide attached device that helps of the knapsack sprayer that uses of the utility model system.

The knapsack sprayer and the human body closed contact of finite concentration agricultural chemicals is equipped with in use, and careless slightly, soup easily spatters, leaks on health, causes operator's pesticide poisoning phenomenon to happen occasionally.

The purpose of this utility model just provides a kind of automatic dispensation apparatus of atomizing cone, and it can avoid pesticide liquid to spatter on the leakage health, improves the safety that atomizing cone uses.

The realization of the purpose of this utility model has two kinds of independently schemes.

Scheme one: between the switch of knapsack sprayer and shower nozzle, set up dispenser (I type).This device is formed (see figure 1) by two essential parts of interior pipe that outer tube and diameter are significantly less than outer tube.Interior pipe slightly is longer than outer tube, and outer tube is sealed at both ends, forms the darkroom like this between the inner and outer pipes and is used for splendid attire pesticide liquid, i.e. coyote hole.Coyote hole borrows a micropore of inner tubal wall front portion to communicate with interior tube chamber, and protrude and forms negative pressure chamber the interior forward side of inner tubal wall, and interior pipe two ends communicate with the spray boom of atomizing cone.With the proper amount of clear water of packing in the atomizing cone staving.During operation, in the clear water with certain pressure is flowed through fast during tube chamber, form and spray after soup in the vacuum suction coyote hole enters tube chamber and mixes with clear water.

Scheme two: between the switch of knapsack sprayer and shower nozzle, set up dispenser (II type).This device constitutes (see figure 2) by a tubular structure and storage medicine bottle.Form negative pressure chamber between the inwall of pipe interior forward side protrusion and the tube wall, the local stenosis place has a micropore to borrow a flexible rubber hose to communicate with the storage medicine bottle throat on the tube wall.The proper amount of clear water of packing in the atomizing cone staving, soup are packed in the storage medicine bottle, and during operation, the pressure (hydraulic) water throat that flows through fast forms negative pressure, attracts storage medicine bottle inner liquid medicine to spray after micropore enters tube chamber and clear water mixes.

The utlity model has following advantage: 1, agricultural chemicals is contained in away from the coyote hole of health or the storage medicine bottle, only contain clear water in the staving of atomizing cone, promptly medicine, moisture from, leak on health even there is liquid to spatter like this, also clear water and do not have any harm has just increased the safety that atomizing cone uses.2, lean on the vacuum suction of current formation to finish voluntarily because original liquid mixes with clear water,, need not to increase any operation bidirectional program so operation is simple especially.3, according to the big or small concentration that determines the dilution that the liquid medicine mixing forms of micro-pore diameter, so more accurate, fixing more at every turn than the concentration of converting pharmacy liquid by hand.

Concrete structure of the present utility model is provided by following embodiment and accompanying drawing thereof.

Fig. 1, Fig. 2 are the section-drawings according to the dispenser of two kinds of schemes that the utility model proposes.

At first describe the details and the service condition of the concrete device of dispenser I type below in detail in conjunction with Fig. 1:

This device comprises outer tube (1) and interior pipe (2), outer tube is sealed at both ends, so between inner and outer pipes, form coyote hole (3), one micropore (5) is arranged on the inner tubal wall of coyote hole front end (9), and protrude and form negative pressure chamber (4) the interior forward side of inner tubal wall, one medicine-pouring hole (6) is arranged on the outer tube wall, be used to inject agricultural chemicals.When pressure (hydraulic) water is flowed through stenosis fast, form the vacuum suction soup and leave coyote hole and mixes the back with clear water and spray.For preventing that cavity appears in the minimizing along with pesticide volume in the coyote hole, pack in the rear end (10) of coyote hole and to be close to the push-plate (7) of inside and outside tube wall, move forward with the elimination cavity by vacuum suction.At the coyote hole rear two induction openings (8) are arranged, be convenient to moving of push-plate.

The concrete device details and the service condition of dispenser II type are described in conjunction with Fig. 2 again.This device is formed by a tubular structure (14) with for the reservoir (13) of containing pesticide liquid, forms negative pressure chamber (11) between the inwall of pipe inside the place ahead protrusion and the tube wall.The proper amount of clear water of packing in the staving of atomizing cone during operation forms negative pressure when pressure (hydraulic) water is flowed through stenosis fast, attract the soup in the storage medicine bottle to spray after micropore (12) enters tube chamber and water mixes.

Claims

1, a kind of dispenser, the attached device that helps as agricultural knapsack sprayer, this device has a coyote hole that is formed by inner and outer pipe (3), it is characterized in that on the inner tubal wall of front end (9) of coyote hole (3) micropore (5) being arranged, and protrude in the anterior inwardly the place ahead of inner tubal wall, form negative pressure chamber (4), the push-plate that can move forward and backward (7) that has a cross-section with it space to match in the coyote hole, there are induction opening (8) and medicine-pouring hole (6) in the coyote hole rear.

2, dispenser according to claim 1 is characterized in that micropore (5) directly communicates with negative pressure chamber (4).

3, dispenser according to claim 1, induction opening (8) is positioned at coyote hole rear end (10), is convenient to moving of push-plate.

4, a kind of dispenser, the attached device that helps as agricultural knapsack sprayer, this device contains tubular structure (14) and storage medicine bottle (13) two parts, the inwall that it is characterized in that pipe forward in the side protrude and form negative pressure chamber (11), and borrow micropore (12) and store medicine bottle (13) and communicate.

5, dispenser according to claim 4 is characterized in that micropore (12) directly communicates with negative pressure chamber (11).

6, dispenser according to claim 4, storage medicine bottle (13) should be subjected to the earth's core effect bottleneck upwards all the time.
