SI20856A - Sprinkler, preferably for plants - Google Patents

Abstract

The sprinkler, preferably for plants ensures sprinkling of liquids, preferably pesticides in such small droplets that they float in the air as an aerosol, and is serving as an attachment to any hand-held motor driven tool, preferably agricultural one, like for example hand-held motor driven mower, as well as of larger type, like a tractor attachment or independent device. The sprinkler consists of an attachment element (1) linking it to any driving generator, for example hand-held motor-driven mower, auxiliary tractor drive etc., a driving shaft (2), which is bearing-fitted in element (1) and provided for the connection to the driving generator via any clutch, while on the shaft (2) next to element (1) there is a fan (3), which is on the side of element (1) implemented with a focusing screen (4). On the opposite side there is a static sphere segment panel (5), which by its convex side fits the fan (3) and by screen (4) forms a focusing channel (6), which leads the air current, created by fan (3), and includes a nozzle (9) for the supply of the pesticide, while on the shaft (2) on the opposite side of the attachment element (1) there is a rotating disc (7), which is of sphere segment shape and which at a distance fits to panel (5) with its concave side, so that their edges form a slot (8).

Description

The subject of the invention

The subject of the invention is a sprayer, preferably for plants, spraying fruit trees and vines against pests and also as a frost protection.

A technical problem

A technical problem solved by the invention is how to design such a device for spraying in particular plants, which will provide a spray of liquid, preferably spray in such small droplets that they will float in the air in aerosol sense and will be feasible as a connection to any hand-held machine device, preferably agricultural such as e.g. mower, but also in a larger version than a tractor attachment or stand-alone device.

The prior art

Known plant spraying devices spray the spray in a liquid by delivering pressurized spray through a nozzle or several nozzles. The spray droplets are such that they tend to fall on the ground, soil or plant parts. On the sloping leaves, many droplets slip to the ground and therefore have no effect.

27956.doc / yy-01 / D26-Vr

The result is a markup on the minimum amount of spray for the intended effect on the plants. A side-effect of the increased amount of spraying of plants is the amount of spraying that falls to the ground, from which it passes into groundwater and finally into drinking water narrows through the roots to the plant, parts of which are intended as food or feed. The final consequence is the content of poisons in food and feed that are harmful to health.

Therefore, there is a need for a plant spraying device that will allow the aerosol spray form in the plant area, and will be of such construction that it is affordable and suitable for installation on agricultural machines, e.g. tractor or smaller, eg: hand mower regardless of the power of its drive unit.

The solution to a technical problem

The described technical problem is solved with a new plant spraying device according to the invention, which is an essential feature and the novelty is that it is made of two concentric calcareous plates, which fit in the distance with the concave parts, one plate rotates and the other is static and it contains a connection to any device on which the drive unit for rotating one bilge plate is located, as well as a liquid spray nozzle through which a spray is fed to the middle part of a rotating plate, which deflects a single spray of spray onto a static plate, from which is again reflected on a rotating plate. At each deflection, the droplet breaks down into smaller droplets that move toward the edge of the plates where the droplets are already small enough to form an aerosol.

The aerosol spray spray floats very long in the air and slowly adheres to the plant parts, especially the leaves. Because the mass of the individual droplets is substantially smaller than the droplets' spray sprayed with known sprinklers, they do not slip from the smooth plant parts. Therefore, the efficiency of the spray is extremely higher than in the known ones

27956.doc / yy-01 / D26-Vr devices. To direct the spray in aerosol form, a sprayer may also be provided on the sprayer to direct the aerosol cloud in the desired direction.

The energy required by the device according to the invention for rotating one plate and, if necessary, the fan, is less than for operating the compressor at known sprayers.

The invention will now be explained in more detail below with a description of an embodiment and the accompanying drawing, in which FIG. 1 is a cross-sectional view of the sprayer according to the invention.

The sprayer according to the invention is made from the connection element 1 to any drive unit, e.g. manual motor mower, auxiliary tractor drive, etc., from drive shaft 2, which is mounted in element 1 and intended to be connected to the drive unit via any coupling not shown in the figure, on the shaft, a fan 3 of any type is provided on the shaft to create an airflow to direct the aerosol plant spray. The fan 3 on the side of the element 1 is made with a smiling screen 4, and on the opposite side of the fan 3 is mounted a static calipers 5, which with its convex side fits into the fan 3. The directional screen 4 and the calipers plate 5 form a directional channel 6 through each other. flowing through an air jet created by the fan 3. Through plate 5 flows a shaft 2, at the end of which is mounted a rotating plate 7, which is cylindrical and, in the offset, fits to the plate 5 with its concave side to form their edges 8. Preferably, both panels 5 and 7 are the same. On static plate 5, a nozzle 9 is fitted with a tube 10 for inflowing liquid spray from a reservoir not shown in the figure. The nozzle 9 directs the jet 1 1 or spray droplets near the center of the rotating plate 7.

27956.doc / yy-01 / D26-Vr

The sprayer according to the invention operates by rotating the rotating plate 7, preferably at 7000 rpm while simultaneously rotating the fan 3 and the sprayer supply through the nozzle 9 onto the rotating plate 8. The spray droplets or spray 11 are broken into smaller ones by contact with the rotating plate 8. drops and bounces to static plate 5, from which smaller droplets bounce back to rotating plate 8. This process is repeated several times until aerosol spray particles reach the edge of both plates 5 and 8 due to the centrifugal force exerted by the rotating plate. 8 do not fly through slot 7 into the surroundings. An air jet created by fan 3, which is directed by flowing through the channel 6, directs the spray aerosol cloud in the desired direction.

The sprayer according to the invention can be made as a connection to any hand-held motorized agricultural machine, e.g. hand mower. In another embodiment, it can be implemented as a standalone machine with its own drive. It can further be made as a tractor attachment. In this case, the tractor attachment may be made with more sprayers according to the invention than a battery according to the intended use.

The size of individual droplets in aerosol form is determined by the speed of the rotating plate, and the amount of aerosol spray is by the inflow of the spray onto the rotating plate.

The sprayer according to the invention can be directed to any position as needed without altering the quality of the spray.

Although the descriptive embodiment of the sprayer is intended for the spraying of plants, especially fruit trees and vines, it is possible to adapt other embodiments for other purposes, e.g. for the application of paints or various liquid preparations to other surfaces where application is required in the aerosol glow of liquids' · without circumventing the essence of the invention as defined in the following claims.
