Abstract

The utility model discloses a sprayer protection casing, it comprises the loudspeaker form upper shield body and protection shirt rim, and the loudspeaker form upper shield body is cavity toper form, has the fixed orifices in the middle of its top reservation, and the underneath perpendicular form of the annular wall of loudspeaker form upper shield body bottom is connected with the protection shirt rim. The utility model discloses spouting the medicine in-process, at first adjusting atomizer spraying switch, make its spraying pressure just make its liquid medicine area that sprays out small in atomizer protection casing bottom annular band shape protection shirt rim end area, spout the medicine in-process, the protection shirt rim can guarantee even atomizer spraying pressure is on can spouting umbelliform liquid medicine of spraying down when too big occasionally to the protection shirt rim inside wall, reaches and stops that it can not spout the purpose on the outer crops of protection casing. The conical structure on the upper part of the sprayer protective cover is more beneficial to the spraying of the pesticide through shuttling movement between the lower part gaps of crops.

Description

Sprayer protective cover

Technical Field

The utility model relates to an agricultural technology gadget especially relates to a sprayer protection casing.

Background

The herbicides are classified into special-purpose killing type, selective killing type (e.g. against dicotyledonous or monocotyledonous killing) and general killing type. However, in the process of spraying the liquid medicine, the spray head of a common sprayer sprays horn-shaped mist liquid medicine, the spray head is higher from the ground, the spray coverage area of the bottom horn mouth is larger, so that the through-killing type herbicide mist is easy to splash onto crops under the condition of no protective cover, the yield is reduced slightly, and the seedlings are killed seriously. The chinese utility model patent No. 2012202209696 discloses a cylindrical sprayer protective cover which can protect the liquid medicine from being sprayed on the crops, but the defect of the cylindrical cover body is small, the spraying area is greatly reduced, and the efficiency is not high; the cylindrical cover body is enlarged, and the difficulty of shuttling movement between crops is greatly increased because the branches and leaves of the crops are staggered and criss-cross in the farmland.

Disclosure of Invention

The utility model aims at providing a simple structure low in cost can effectively protect the liquid medicine not spray crops on, can shuttle easily again and remove the atomizer protection casing between the crops line. The sprayer protective cover consists of a horn-shaped upper cover body and a protective skirt.

The horn-shaped upper cover body is made of light PVC transparent material, is in a hollow conical shape, the top of the horn-shaped upper cover body is a coin-shaped plane, a fixing hole is reserved in the middle of the plane, and the diameter of the fixing hole corresponds to the diameter of a screw opening of the spray head; an annular belt-shaped protective skirt is vertically connected below the annular wall at the bottom of the trumpet-shaped upper cover body.

The protective skirt is made of light PVC transparent material and is in an annular belt shape, the width of the protective skirt is about two centimeters, the top annular wall of the protective skirt is connected to the annular wall bottom at the bottom of the horn-shaped upper cover body, and the connecting method is bonding or integral blow molding.

Drawings

Fig. 1 is a schematic structural view of the sprayer protective cover of the present invention.

Detailed Description

The embodiment of the sprayer protective cover of the utility model is shown in fig. 1, the sprayer protective cover is composed of a horn-shaped upper cover body 1 and a protective skirt 3, the horn-shaped upper cover body 1 is made of light PVC transparent material and is in a hollow inverted cone shape, the top of the horn-shaped upper cover body is a coin-shaped plane, a fixing hole 2 is reserved in the middle of the plane, and the diameter of the fixing hole 2 corresponds to the diameter of a screw opening of a spraying head; an annular belt-shaped protective skirt 3 is vertically connected below the annular wall at the bottom of the trumpet-shaped upper cover body 1; the protective skirt 3 is made of light PVC transparent material, is in an annular belt shape, has the width of about two centimeters, and has the top annular wall connected to the annular wall bottom at the bottom of the trumpet-shaped upper cover body 1 by bonding or integral blow molding.

When the sprayer protective cover of the utility model is used, the spray piece fixing nut on the spray head is firstly removed, then a screw hole of a fixing hole reserved at the top of the horn-shaped upper cover body of the sprayer protective cover is sleeved on a screw hole of the spray head, then the sprayer protective cover can be fixed on the spraying head by screwing down the spray piece fixing nut, in the spraying process, firstly, the spray switch of the sprayer is adjusted to ensure that the spray pressure is just good and the area of the liquid medicine sprayed by the spray switch is tiny to the area of the lower opening of the annular band-shaped protective skirt at the bottom of the protective cover of the sprayer, then the protective cover of the sprayer is shuttled between crops to spray the pesticide, in the pesticide spraying process, the protective skirt edge can ensure that the sprayer can spray liquid medicine sprayed downwards in an umbrella shape to the inner side wall of the protective skirt edge even if the spraying pressure of the sprayer is occasionally too high, so that the aim of preventing the liquid medicine from being sprayed to crops outside the protective cover is fulfilled. The conical structure on the upper part of the sprayer protective cover is more beneficial to the spraying of the pesticide through shuttling movement between the lower part gaps of crops.

Claims

1. The sprayer protective cover is composed of a horn-shaped upper cover body and a protective skirt edge, and is characterized in that the horn-shaped upper cover body is in a hollow conical shape, the top of the horn-shaped upper cover body is a coin-shaped plane, a fixing hole is reserved in the middle of the plane, and the diameter of the fixing hole corresponds to the diameter of a screw opening of a spraying head; a protective skirt is vertically connected under the annular wall at the bottom of the trumpet-shaped upper cover body.

2. The nebulizer shield of claim 1, wherein the protective skirt is in the form of an annular band having a top annular wall attached to an annular wall base at the bottom of the upper horn-shaped housing.
