Field of technology

The utility model refers to a portable hand-held agricultural sprayer, with two modular chemical containers, which are for sequential use when spraying chemicals on crops and weeds, finding application in agriculture.

BACKGROUND OF THE INVENTION

A hand-held portable agricultural sprayer of the utility model BG 2452 U1 is known, which is in the form of a backpack, including belts for attaching them to the sprayer operator and consists of two modular containers attached by an assembly to each other, the first container being a herbicide and the second container is for a herbicide neutralizer. There is a herbicide cap to the opening of the first container, and on its front surface there is an air valve and a first ribbed connection nozzle, to which the first flexible hose is mounted. To the opening of the second container there is a cap for herbicide neutralizer, on the front surface of which there is an air second valve and a second ribbed connection nozzle, on which the second flexible hose is mounted. The first and second flexible hoses are connected to a trigger mechanism, with a handle in which the flexible hoses are located therein, the first flexible hose being connected to a first herbicide valve and the second flexible hose being connected to a second herbicide neutralizer valve, such as each valve is connected by a pin mounted above the handle. Two pipes, respectively a first and a second pipe, are mounted to the trigger mechanism, the first pipe being connected by the first valve to the first flexible herbicide hose and the second pipe by the second valve connected to the second flexible herbicide neutralizer hose, the two pipes being fixed to each other by means of a bracket. At the end of each pipe is a first herbicide nozzle and a second herbicide neutralizer nozzle mounted in a tubular housing. In an alternative embodiment, the first and second tubes are designed as telescopic tubes in which a movable telescopic nozzle with the possibility of extension if necessary is mounted by means of screw connections in their inner volume.

U.S. Patent No. 2013,186,977 is known for a portable sprayer designed as a backpack for a sprayer operator having more than one multi-container, with a pump for injecting chemical liquids. The containers are connected by means of flexible hoses with a trigger mechanism, with a handle, and a main pipe ending with a nozzle is mounted to the trigger mechanism. The trigger mechanism controls the choice of the specific chemical from the containers required for spray injection through the nozzle user through the nozzle mounted to the main pipe. The chemical in the containers is pressurized and manually pumped to the nozzle. The pump is able to turn the liquid back to the feed container, for which purpose there are selected collectors, acting as a starting mechanism, located outside the pipes of the pipeline, which has a bracket with valves. In addition, separate return tubes are provided for each chemical from the collector back to the containers of origin, the collector allowing convenient flushing of each chemical back to its container of origin. This ensures that the chemicals are not mixed or contaminated, as any residual liquid from the chemical is returned to the respective container. The collector is attached to the operator's thigh for easy access. Because this sprayer only sprays chemicals in the form of a spray, it is not suitable for injecting chemicals under a thin stream, on a specific plant or weed, or on a specific fixed small space.

Technical essence of the utility model

The task of the utility model is to create a portable hand-held agricultural sprayer that is for consistent use in the injection of chemicals on crops and weeds, is easy to handle and maintain, to inject a chemical in a thin stream of specific plants and weeds, as well as to keep the neighboring useful plants intact, as well as to be convenient for assembling and cleaning the containers.
