Eine Vorrichtung zum Spritzen von Reihenkulturen weist einen von einem Fahrzeug, einem Anhänger od. dgl. aufgenommenen Spritzmittelbehälter und wenigstens einen eine Pflanzenreihe (3) übergreifenden Spritztunnel (1) mit beiderseits der Pflanzenreihe (3) abstandsveränderlich angeordneten Seitenwänden (6), entlang deren Unterkante je eine Sammelrinne (13) zum Auffangen und Rückgewinnen von überschüssigem Spritzmittel angeordnet ist, und innerhalb des Spritztunnels (1) im wesentlichen senkrecht verlaufende Düsenrohre (11) auf, wobei die Tunnelweite an dem in Fahrtrichtung vorderen und hinteren Ende des Spritztunnels etwa der Pflanzenbreite entspricht. Zur Verbesserung des Spritzergebnisses ist vorgesehen, daß sich die Tunnelweite vom vorderen Ende ausgehend bis zu einem größten Abstand der Seitenwände (6) erweitert und danach zum hinteren Ende wieder verengt.

Dosing plant (1) for dosing a liquid (L); the dosing plant (1) comprising at least one tank (20) for the liquid (L) ; a dispensing member (32) hydraulically connected to the tank (20) and supplied, in use, by a pump (40) electrically actuated and hydraulically connected to the tank (20) through a supply pipe (50) and to the dispensing member (32) through a dispensing pipe (52); a power supply device (60) is electrically connected to the pump (40) for the actuation thereof; a control device (70) being electrically connected to the power supply device (60) and electronically connected to the pump (40) in order to control the operation thereof; The dispensing member (32) comprises an injector (34) electrically connected to the power supply device (60) and electronically connected to the control device (70) in order to dose the liquid (L) in a calibrated manner and to optimize the use thereof.
摘要:
The present invention provides an irrigation system. The irrigation system includes a supply module, a transport pipeline, a spraying module, and a control module. The supply module includes a plurality of supply apparatuses for storing a plurality of feeding liquids. The control module controls the supply module to provide different feeding liquids at different time, and the different feeding liquids pass through a same segment of the transport pipeline at different time and flow to an irrigation area. The present invention further provides a method for controlling an irrigation system, and a control module controls different feeding liquids to pass through a same segment of a transport pipeline at different time and flow to an irrigation area. In the irrigation system, by using a same segment of the transport pipeline at different time, a quantity of pipelines of the irrigation system is reduced, so as to lower difficulty of arrangement of pipelines by a user, avoid affecting appearance, and reduce costs of the user.
摘要:
An irrigation system is provided for irrigating a field divided into irrigation zones. The irrigation zones are arranged in columns extending alongside each other. The system has irrigation strips and a control head at an upstream end of each irrigation strip. Each irrigation strip provides irrigation substances to a column of zones. All control heads are located alongside a boundary of the field outside of the irrigation zones. This permits maintenance of the control heads without the need to enter the irrigation zones.

Provided are a mosquito control aerosol which can produce a good control effect on mosquitoes over a long period of time while reducing influence on humans and pets, and a mosquito control method using the mosquito control aerosol. The mosquito control aerosol includes: a pressure-resistant container equipped with a metering spray valve, that contains a liquid aerosol-forming material including an insect pest control component and an organic solvent, and a propellant; and a spray button having a spray outlet connected to the metering spray valve. The volume of the liquid aerosol-forming material sprayed when the spray button is pressed down once is adjusted to 0.1 to 0.4 mL, and the spray force thereof as measured at a distance of 20 cm from the spray outlet at 25°C is adjusted to 0.3 to 10.0 g·f. At least a portion of the liquid aerosol-forming material is sprayed from the spray outlet in the form of adhesive particles X which adhere to an exposed portion in a treatment space. Alternatively, the liquid aerosol-forming material is sprayed from the spray outlet in the form of adhesive particles X which adhere to an exposed portion in a treatment space and suspendable particles Y which suspend in the treatment space.
摘要:
Spraying equipment, for example for applying herbicide, comprises a spraying head (6) mounted on one end of a support tube (2), the other end of which is adapted to be held by an operator. The spraying head (2) comprises a body (48) which accommodates an electric motor (50) and a polygonal spraying disc (54) which, in operation, is driven by the motor (50). Liquid is supplied to a fluid-receiving surface of the disc (54) through a supply tube (38) and power is supplied to the motor (50) through a lead (36). Upon rotation of the disc (54), fluid is ejected by centrifugal force from the periphery of the disc (54). The fluid receiving surface of the disc meets side surfaces (126) at the periphery. These side surfaces (126) are parallel to the rotary axis of the disc (54). As viewed perpendicular to the rotary axis, the outer periphery is not planar. 9
