Description

Intercostal spraying device attached to a power sprayer

The present invention aims to reduce drift damage from the standpoint of compliance with the positive list system, to prevent environmental pollution and safety, and to minimize the impact on other adjacent crops. The present invention relates to a furrow spraying device for side spraying from a furrow or low-position low-pressure spraying.

In general, high-pressure spraying from the top surface is commonly used for spraying chemicals to field crops. However, recent trends have led to the spread of drift-reducing nozzles and low-pressure small-water spraying. Especially in herbicide spraying, the upper layer of the crop becomes a kind of shielding wall and the herbicide does not reach the plant stock and the herbicidal effect is not fully demonstrated. Since then, the necessity for spraying stocks has increased and the spread of root sprayers has been promoted.

When switching from full surface spraying to intercostal spraying, which was considered to be a problem with conventional root drug spreaders, the spray bar is directly tied to the sprayer boom with a rubber belt, and a number of nozzles are removed one by one to remove the chemical hose. There was a tendency that it was not fully utilized, including the connection to the nozzle and covering the nozzles that were not used to return to the original shape of the entire surface spraying.

With the introduction of the positive list system, reduction of environmental impact due to drift, ensuring safety, and avoiding the impact on other adjacent crops are major issues. On the other hand, it is possible to realize a spraying device in an easy-to-use form in order to spread and expand the entire surface spraying from the upper surface to the intercostal side surface spraying and the low pressure low position spraying.

A liquid distribution pipe integrated with the spray bar set is provided in order to perform quick and simple operation of attaching and detaching the power sprayer main body boom and the intercostal spray device according to claim 1, and the liquid distribution pipe is attached to the sprayer main body boom. The holding metal fitting to hold | maintain is arrange | positioned, and this three liquid distribution pipes are arrange | positioned to the sprayer main body rear part and the left and right main body boom. The main chemical solution hose is attached to the end of the three main chemical solution hoses on the sprayer main body side, the end of the distribution pipe, and the end of the sprayer main body boom to which the connecting coupler is attached and sprayed. Connect. The switching operation in the case of spraying the entire surface from the upper surface is performed by removing the main chemical solution hose from the distribution pipe and connecting it to the coupler of the main body boom, and the distribution pipe and the distribution bar set attached to the main body boom. The structure can be removed by simply removing the clasp from the fixing bracket.

The spray bar, which is tightly bound by fasteners to the three distribution pipes arranged on the left, right, and center of the sprayer body boom according to claim 1, touches the center of the target crop. Depending on the type of the sprayer body and the width of the hail, a considerable number of hail treatments are possible.

The spraying device according to claim 2 can be arranged from one stage to a plurality of stages by connecting a branch pipe made of reinforced resin having a hook-shaped contact portion with the ground and having a three-fork spray hole with a hose.

In the pest control of the spraying device according to claim 2, the number of stages is set from one to several while observing the growth of the target crop, and the center part of the three-forked branch pipe is covered with a mekra lid. Side spraying is performed with two spray holes of the fork.

In the herbicide spraying of the spraying device according to claim 3, the height and angle are set by the fasteners so that a fan-shaped spraying shape with a ridge width as a base is obtained by mounting a low-pressure fan nozzle and a scattering prevention cover. To do.

In pest control according to the present invention, set the height and angle to be sprayed according to the type and growth of the crop from the spray bar located in the center of the intercostal space, so that the medicinal solution is sufficiently distributed over the back and the whole foliage, In addition, for herbicide spraying, a positive list system, such as treating the weeds of furrows and stocks while reducing drift by installing a spray-proof cover and a low-pressure fan nozzle on the spray bar to form a fan spray. This makes it possible to spread rational drugs such as reducing environmental impacts, minimizing the impact on other crops, and ensuring safety.

Implementation of the present invention The tractor-mounted power sprayer is installed at the rear of the main unit, and the riding type control machine is installed at the front of the main unit.
