Over-line spray boom with hydraulically adjustable spray channel width and spray liquid Recovery for plant protection in agriculture, in particular in viticulture and fruit growing

The invention relates to a new type of spray boom, especially for winter and shoot spraying in viticulture and fruit growing. These injections the z. B. to fight the "red spider" and the "black spot disease" make a very strong one ! Moistening of the bog vines and the vine trunk necessary. A leaf wall is not yet in place for these spraying dates.

The winter and shoot spraying was previously carried out with the hand spray tube or an over-line rod. The previous over row linkage has the shape of an inverted "U", which receives the vine row in its center. On the vertical legs of the upturned ¹¹ U ", the distance between which is not hydraulically adjustable, there are spray nozzles which are directed inwards, ie towards the vine row. During the spraying process, the vine is wetted from both sides. that the liutzflache _t ie Pogreben and Rebstainm, is very small compared to the total spray area, which results in a considerable loss of spray liquid. In other words, in order to wet the vine wood and the vines well (dripping wet), the majority of the spray liquid is accepted that does not hit the vine, falls unused to the ground, which is tantamount to severe environmental pollution, and the driver is also heavily contaminated by the spray mist.

The previous one, from the state teaching and research institute Neustadt a. d. Weinstrasse, for this spraying process recommended guideline value is 600-800 l / ha.

The invention has now set itself the task of drastically reducing the loss of spray liquid and thus to achieve a reduction in the amount of effort per hectare and to enable user-friendly handling.

The solution to the problem was found in the fact that a syringe of known type, a new overline linkage (Schematic diagram) was constructed. A mounting bracket (1) was attached to the substructure of the sprayer. In a horizontally mounted flat guide (2), an equally shaped bracket (4) can be used with the help of a double-acting lifting cylinder (3) can be extended and retracted. This results in the new possibility to vary the working width (spray channel) of the spray boom continuously and hydraulically. On the outside of the boom (4) is a square tube (7) and an adjusting screw (6) a vertical downwardly directed U-profile (11) attached. This takes three spray nozzles (19) and the necessary ones Supply hose and with the help of flat material (13) carries a bulkhead (polyacrylic) (12) 800mm χ 1000mm. The spray nozzles extend through the plexiglass plate. At the end of the plate, seen in the direction of travel, there is an inward (towards the row of vines) arched one Falling rubber (15) attached. Both the bulkhead and the catch rubber open into one at the bottom Collecting container (16). This container has a cover plate (18) which is bent inwards in a funnel shape,

and pure collecting tank (17) of a small submersible pump (12 V). The described arrangement (11 ♦ 20) is a mirror image on the frame (1) again brought in and thus forms a spray channel.

Further features of the invention emerge from the following description of an exemplary embodiment with the drawing and the claims.

It show in schematic sketches,

The new overline sprayer boom is mounted on a sprayer of a known type. To move into the row of vines, the over-row linkage is adjusted to the desired width of the spray channel by means of the double-acting lifting cylinder (3). By turning on the Schleppereapfwelle that drives the syringe pump _t the spray nozzles (19) are supplied with fuel by a known liquid system. The liquid emerges from the nozzles {19), partly wets the vine as desired, and partly flies to the opposite bulkhead, hits there, runs down it into the collecting container (16), from there into the collecting container (17) , is sieved and fed with the submersible pump, which is connected to the tractor's 12 7 system, via a return line

Tsnk the syringe pumped. This principle works on both sides. The cover plate (18), which is bent like a funnel into the collecting container (16), prevents it from sloshing out the regained spray liquid during the spraying process. The inside, towards the row of vines Curved catch rubber (15) fulfill two tasks:

a) The spray liquid that is blown up is deposited on the rubber and becomes the collecting container as a result of the molding fed.

b) the air flow created by the journey in the spray channel, which carries the spray liquid with it, becomes guided through the curved rubber to the vine, which causes renewed wetting.

The hydraulic level adjustment of the over-line sprayer enables the operator to operate as tightly as possible Establish spray channel, which benefits an optimal spray liquid recovery.

Tests by the state teaching and research institute Neustadt ad Weinstrasse have shown that the amount of effort required can be reduced by at least 50% with the device according to the invention. This has the following advantages:

a) a significantly lower environmental impact

b) the spray liquid drifts off through the spray walls on the tractor driver

c) The costs of winter and shoot spraying can be reduced by at least 50%.
