Nozzle head on agricultural spraying devices

The invention relates to a nozzle head in agricultural sprayers which is provided in a housing with a swirl body with a nozzle plate that can be changed at a distance therefrom 1st.

In most cases of agricultural spraying devices, emulsions, Suspensions or solutions depending on nozzle mouthpieces with a certain amount of spray the spray pressure and a certain spray jet that cannot be changed.

·. The present invention has the task of
Avoid d ± e disadvantages of the known nozzles by
a twist body spindle is provided in the housing,
the upper end of which is led out of the housing and connected to
the head of an eccentric lever by means of a bearing pin
is eccentrically supported, in the housing, axially
running to the spindle, a compression spring2 is arranged,
which is supported on the swirl body and on the housing.

A design according to the invention eioht that the Has the head of the eccentric lever a polygonal profile.

■ ^r '*. According to a further proposal of the invention, the procedure is such that transverse bores are provided at different heights in the upper end of the twist body spindle, a hairpin safety device being insertable into the respective bore to fix the spindle.

Another design according to the invention consists in

'that on the housing a ring body with different

> deep grooves is arranged, being in the upper end

a pin is attached to the swirler spindle, which is used to gradually adjust the stroke of the swirler in the *. - Grooves entered.

The inventive embodiment has the advantage

can be adjusted in steps so that the application rate the single nozzle or all of them? SPRAY NOZZLES? where these can be set differently from one another, depending on the static fluid pressure clearly ' is definable.

Further features of the invention emerge from the following description of an exemplary embodiment in FIG Connection with the drawings and claims.

It show, in schematic sketches,

Figure 1 is a longitudinal section through a nozzle head according to the invention,

Figures a view of the DUsenkopfes with different eccentric lever positions,

Figure 6 shows another embodiment of the

upper shower head, ■

Figure 7 is a plan view of Figure 6, ·.

Figure 8 shows a further embodiment of the upper nozzle head and

Figure 9 is a plan of Figure 8. ·

The nozzle head shown in FIG. 1 has a housing 4 which has a locking nut 6 on the outlet side of the spray device. In your housing 4 a swirl body spindle 10 is arranged _f which carries the swirl body 9 at its lower end and is led out of your housing h at its upper end . The upper end of the swirl body spindle 10 is held on the head i4 of an eccentric lever 15 by means of a bearing pin 13. The head 14 of the eccentric lever 15 has a polygonal profile, the individual surfaces of which rest on a disk 12 on the housing 4 in the respective lever position. The housing 4 is sealed at the top by means of a seal 5. In the housing 4, axially to. Spindle. 10, a compression spring 11 is arranged, which is supported on the swirl body 9 and on the housing 4. Between the closure nut 6 and the swirl body 9 is a nozzle plate 7 with a sealing washer

provided, | wherein in the closed state of the nozzle the end face of the swirl body 9 on the. Sealing washer 8 rests. For connecting the nozzle head. . ' ■ on the side of the housing k ^ a connection nipple 3 is provided on the spray agent line, which has a union nut 1 and a seal 2 ..

With the help of the eccentric lever 15, which can be brought into different positions, for example zero, one, two, three (Figures 2 to 5), the swirl body is changed in ₍ its axial position so that the distance between the swirl body 9 and the Nozzle plate 7 is changed in steps. This also changes the spray angle of the spray steel, but with each setting of the eccentric lever 15 an exact flow rate of the spray depending on the • static liquid pressure can be defined.

It is easily possible to determine the number of intermediate divisions of the eccentric lever 15 to enlarge.

Likewise, instead of the eccentric lever 15, the head lU can be provided with a key surface i whereby the lever 15 is omitted.

In Figures 6 and 7, a further embodiment for the gradual adjustment of the swirl body 9 is shown, wherein transverse bores 17 are arranged at different heights in the upper end of the swirl body spindle and a hairpin retainer can be inserted into the respective bore 17 to fix the spindle 10.

According to FIGS. 3 and 9, a pin 18 is fastened in the upper end of the swirl body spindle 10. On the housing h there is an annular body 1 *? In which grooves 20 of different depths are incorporated into which the pin.18 to set the respective
Lift position of the swirl body 9 can engage.
