Definitions

  • the invention relates to a hand-operated device for spraying water, in which an additive in the form of a liquid concentrate, such as a crop protection agent, is mixed, consisting of a spray tube with a spray nozzle and a hand valve upstream of the spray tube with a pressurized water connection.
  • an additive in the form of a liquid concentrate such as a crop protection agent
  • Devices of this type are usually used in crop protection sprayers and are connected to a portable pressure container via their pressure water connection by means of a pressure hose.
  • This pressure vessel absorbs the water already mixed with the respective additive and can be pressurized by means of a hand-operated or motor-driven air pump, which forms an air cushion above the liquid level in the pressure vessel.
  • the invention is therefore based on the object of providing a device of the type mentioned at the outset in which the smallest possible number of parts is contaminated with the concentrated additive and which enables a controlled admixture of the concentrated additive to the water to be sprayed.
  • an admixing device is arranged between the hand valve and the spray tube, which has a mixing head on which the spray tube and a cartridge receiving the concentrate are detachably attached and on which one of the Manual valve coming water supply line is connected, and which further has a pressure piece acting on the cartridge for the purpose of introducing the concentrate into the mixing head, which is coupled to a feed drive which is controllable depending on the actuation of the manual valve and which is also arranged on the admixing device.
  • a further advantage is that the feed drive for the pressure piece is only started when the water supply to the mixing head is released via the manual valve.
  • a pressure regulator which is usually designed as a pressure limiter, is expediently located in the water supply line connected to the mixing head, in order to ensure a constant water flow through the mixing head, to which the concentrated additive is continuously admixed in the same way.
  • a pressure sensor can be provided in the water supply line to the mixing head, which stops the feed drive for the pressure element acting on the cartridge when the pressure falls below a predetermined pressure.
  • the device shown consists of a spray tube 1, at the free end of which a spray nozzle 2 is arranged.
  • the device has a handle 3 designed as a feed pipe, at the end of which there is a pressurized water connection 4.
  • This pressurized water connection 4 can be connected to an existing water network, such as the public water network, or to a pressure container which can be pressurized by means of an air pump and which receives the water to be sprayed, but into which the concentrated additive to be mixed with the water is not to be entered. It is understood that a corresponding hose connection is established between the water source in question and the pressurized water connection 4.
  • a manual valve 6 which is a so-called quick-closing valve.
  • a valve opens fully when actuated via the hand lever 5 and closes immediately when the hand lever 5 is released.
  • the water inlet to a mixing device 7, which has a mixing head 8, is released via the manual valve 6.
  • the mixing head 8 has a mixing channel 9, in which an end connection part 10 of the spray tube 1 and a connection piece 11 can be inserted coaxially opposite one another, of which the connection piece 11 is part of a cartridge 12 which contains the concentrated additive to be mixed with the water.
  • a channel 13 opens into the mixing channel 9 of the mixing head 8, to which a water supply line 14 coming from the manual valve 6 is connected, which can be integrated in the frame of the admixing device 7.
  • the mixing of the water supplied via the water supply line 14 in the mixing head 8 takes place in the mixing channel 9, in which the concentrated additive is added to the water in a short way and the water mixed with the additive is introduced into the spray tube 1.
  • the cartridge 12 At the end of its connector 11, which is inserted into the mixing head 8, the cartridge 12 has a check valve 15, which closes the cartridge 12 as soon as the liquid, concentrated additive in the cartridge 12 has fallen below a predetermined pressure or is depressurized is.
  • the filling chamber 16 of the cartridge 12, in which the liquid additive is received is designed as a cylinder, in which there is a displaceable sealing piston 17, which can be acted upon by a pressure piece 18 on its outside.
  • the pressure piece 18 is movable coaxially to the cartridge 12 and carries out such a stroke that the piston 17 can be displaced up to the connection piece 11 within the filling space 16 in order to press the concentrate to be mixed into the water completely out of the cartridge 12.
  • the special feature is that the feed of the pressure piece 18 is controlled as a function of the water supply to the mixing head 8. Because based on the flow rate which is introduced into the spray tube 1 via the mixing head 8, the liquid, concentrated additive is proportionally added to the water in order to achieve the appropriate concentration of the additive in the water to be sprayed.
  • the translatory displacement of the pressure piece 18 takes place via a feed drive 19, which expediently has an electric motor with a gearbox with a linear output. This electric motor can be supplied via a battery or a rechargeable battery 21, which is arranged on the admixing device 7.
  • the control of this electric motor and thus of the feed drive 19 takes place via a pressure regulator 20 which is arranged on the water supply line 14 leading to the mixing head 8 and is located behind the hand valve 6 in the feed direction. Via the pressure regulator 20, the pressure in the water supply line 14 is limited to a certain pressure, on which the temporal flow rate of the water through the mixing head 8 depends. Then the feed of the pressure piece 18 via the feed drive 19 is switched off so that the appropriate amount of the concentrated additive in the mixing channel 9 is added to the water from the cartridge 12.

Abstract

L'invention concerne un dispositif à commande manuelle servant à pulvériser de l'eau. Ce dispositif comprend un tube de pulvérisation (1) doté d'une buse de pulvérisation (2) et une soupape manuelle (6) placée en amont du tube de pulvérisation (1) et comportant un raccord d'eau sous pression. Un dispositif mélangeur (7) à tête mélangeuse (8) est disposé entre la soupape manuelle (6) et le tube de pulvérisation (1). Le tube de pulvérisation (1) et une cartouche (12) contenant le produit concentré sont reliés mobiles à cette tête mélangeuse (8), à laquelle est raccordé un conduit d'amenée d'eau (14) en provenance de la soupape manuelle (6). Le dispositif mélangeur (7) comprend en outre un élément de pression (18) alimentant la cartouche (12) pour permettre l'introduction du produit concentré dans la tête mélangeuse (8), cet élément de pression étant relié à un mécanisme d'avance (19) commandable en relation avec l'actionnement de la soupape manuelle (6) et également disposé adjacent au dispositif mélangeur (7).
