Device for cleaning the suction system of agricultural sprayers

Abstract

A device that allows the suction circuits of sprayers to be cleaned without handling and without pollution. The invention relates to a device that can be placed at the end of universal suction filters, with a fitting the diameter of the existing filters 3, an extended part to open the suction filter flap 4, a collar 5, resting on the filter element provided for this purpose, a thread 6 to connect the clean water hose, and an element for the passage of clean water from the outside to the inside 7.

Description

Title of the invention: Device for cleaning the suction system of agricultural sprayers

[0001] The present invention relates to a device for preventing fouling of heavy copper-based products and any other active material in sprayer tanks.

[0002] To date, there is no solution other than the operator removing the sprayer's suction filter and pipes to unclog them, which risks poisoning the user and polluting the soil.

[0003] The device of the invention makes it possible to remedy this drawback; it has, in fact, a first characteristic: an element that is placed on the push-pull type valve, which allows clean water to be injected from the outside to the inside. This element, which allows clean water to be injected without pollution, is provided with a fitting in the suction filter and retained by a nut with a gas thread.

[0004] According to particular embodiments, this element is housed in place of the traditional valve system which is used to open the filter.

[0005] The attached drawings illustrate the invention, photo 1 representing the device of the invention, which is put in place of the universal flap of the suction filter photo 2, with reference to my drawings, to my photos, the device includes an element which comes in place of the flap, of the suction filter.

[0006] The length of this element and the machining to the diameter correspond to the integral fitting into the suction filter. With an extension that presses against the valve for the feed.

[0007] This device can be made of any metallic material, stainless steel, copper, brass, or any plastic material. This device is also available in several diameters, corresponding to the different suction filters of universal sprayers.

[0008] Photographic drawing 1 illustrates the invention and represents the device of the invention. Photographic drawing 2 represents the push-pull system for opening the suction filter flap.

[0009] Device for eliminating all deposits in a sprayer circuit without any manual handling and without any pollution. (1) Having a cylindrical portion. (2) Which fits into any universal sprayer suction filter, with a lengthwise element which allows the flap of its suction filters to be opened. (3) With a gas thread (6), which allows the connection of the clean water hose.

Claims

Demands

1. A device for removing deposits from sprayer suction filters without handling, without direct contact with active ingredients, and without any soil pollution, comprising a clean water passage element (7), a gas thread (6), and a support flange (5). This gas thread (6) is screwed onto the suction filter in place of the valve (photo 2), connecting the clean water passage element 7, which rests on the support flange (5), to the suction filter.
