Abstract

A field crop spray apparatus comprises a carrier, at least one frame connected to the carrier and present at the bottom thereof, an elongated blade connected to the frame and running parallel to the carrier, and a sprayer. The field crop spray apparatus is intended to be mounted on an agricultural spray apparatus where the carrier extends at right angles to the direction of movement of the agricultural sprayer. The dosing of the sprayers can be adjusted and the spray apparatus comprises a control unit that adjusts the dose to the speed at which the apparatus is moved over the crops so as to spray the same quantity of spray liquid per unit of area.

Description

FIELD CROP SPRAY APPARATUS FOR SPRAYING CROPS WITH LIQUIDS
DESCRIPTION: Field of the invention. The invention relates to a field crop spray apparatus for spraying crops with liquids, the apparatus comprising an elongated carrier, a plurality of frames connected to the carrier and present at the bottom thereof, an elongated blade connected to the frames and running parallel to the carrier, and sprayers connected to the blade, which field crop spray apparatus is intended to be coupled to an agricultural tractor where the carrier extends at right angles to the direction of movement of the agricultural tractor.
State of the art.
A field crop spray apparatus of this kind is known from EP-A-1 083 789. In this known field crop spray apparatus frames present between the carrier and the blade are made of an elastic material. Owing to undulations of the ground the carrier moves up and down during the use of the field crop spray apparatus. During a down movement of the carrier the blade meets with more resistance from the crop so that the frames spring inwardly. As a result, the sprayers continue to maintain their distance from the crop, so that the liquid is distributed uniformly over the crop.
Summary of the invention.
It is an object of the invention to improve the known field crop spray apparatus. To this end the field crop spray apparatus according to the invention is
characterised in that the dosing of the sprayers can be adjusted and the spray apparatus comprises a control unit that adjusts the dose to the speed at which the apparatus is moved over the crops so as to spray the same quantity of spray liquid per unit of area. In
consequence, there is no what is called lagging effect of the control, so that with this application dose differences per unit of area or crop are avoided. An embodiment of the field crop spray apparatus according to the invention is characterised in that the dosing of the sprayers can be adjusted individually or in groups so that it is possible to spray more at places where there are more or larger weeds or even spray less at places where this may lead to damaged crops and thus realize that less chemical agents are used.
It should be observed that this embodiment can also be applied independently of the measures for adjusting the dose in dependence on the rate of movement.
Description of an embodiment.
A field crop spray apparatus comprises an elongated carrier, a plurality of frames connected to the carrier and present at the bottom thereof, an elongated blade connected to the frames and running parallel to the carrier, and sprayers connected to the blade, which field crop spray apparatus is intended to be coupled to an agricultural tractor where the carrier extends at right angles to the direction of movement of the agricultural tractor.
The dosing of the sprayers is adjustable and the field crop spray apparatus comprises a control unit that adjusts the dose to the rate of movement over the crop, so that the same quantity of spray liquid per unit of area is sprayed. This leads to the lack of the what is called lagging effect of the control, so that dose differences per unit of area or crop are avoided with this application.
The dosing of the sprayers can be adjusted individually or in groups so that it is possible to spray more at places where there are more or larger weeds or even spray less at places where this may lead to damaged crop and thus realize that less chemical agents are used.
For the speed-dependent control is used a ring line that is under higher pressure than the maximum set pressure of a sprayer or of a section of sprayers, so that for each section of sprayers or for each sprayer a lower pressure can be set so that different pressures and thus different deliveries can be set per section or sprayer.

Claims

CLAIMS:
1. A field crop spray apparatus for spraying crops with liquids, the apparatus comprising an elongated carrier, a plurality of frames connected to the carrier and present at the bottom thereof, an elongated blade connected to the frames and running parallel to the carrier, and sprayers connected to the blade which are spread over the length of the carrier, which field crop spray apparatus is intended to be coupled to an agricultural tractor where the carrier extends at right angles to the direction of movement of the agricultural tractor, characterised in that the dosing of the sprayers can be adjusted and the spray apparatus comprises a control unit that adjusts the dose to the speed at which the apparatus is moved over the crops so as to spray the same quantity of spray liquid per unit of area.
2. A field crop spray apparatus as claimed in claim 1 , characterised in that the dosing of the sprayers can be adjusted individually or in groups so that it is possible to spray more at places where there are more or larger weeds.
