Description

Hose reel integrated electric agrochemical spray device

The present invention relates to a hose reel-integrated electric pesticide spraying device, and more particularly, to a hose reel-integrated electric pesticide spraying device that pumps a chemical solution stored in a medicine bottle at high pressure and sends it to a required spraying point through a hose wound around a hose reel for spraying. It relates to pesticide spraying devices.

A pesticide spraying device, which is usually used for the purpose of preventing diseases or pests of various crops, consists of components such as an engine (using an engine mounted on agricultural machinery or a separate engine, etc.), a pump, a pesticide hose, a medicine bag, and a medicine box.

Among them, in the case of engines required to drive pumps, engines installed in various agricultural machines are often used or electricity is used, but compatibility with agricultural machines is lacking, agricultural machines themselves that can be used are absent, or areas where access to agricultural machines is difficult, and electricity In areas where it is difficult to connect to an engine, an engine pump with an engine is often used.

In addition, the pesticide hose is very long to enable easy spraying of the pesticide pumped from the pump to crops in distant places, and if not organized, there is a high risk of entanglement and it is difficult to move because of its large volume. It is common to use a hose reel that allows long hoses to be wound and unwound in a well-organized state.

However, the conventional configuration of the engine pump and hose reel for pesticide spraying is not only separately manufactured, but also requires considerable labor and time to move and prepare the engine pump and hose reel individually when installing the pesticide spraying device. Waste factors, as well as waste factors in manufacturing processes and costs, are also large, and furthermore, considerable inconvenience is followed during use and manipulation, and at the same time, there is an inconvenient disadvantage that each product must be purchased separately at the time of purchase.

On the other hand, in order to overcome this problem, Korean Utility Model Publication No. 20-2010-0004153 discloses an engine-type pump installation unit capable of fixed installation of an engine-type pump integrally composed of a small engine and a pump on one side, and the other side of the engine-type installation unit. On one side, a hose reel installation unit for fixed installation of a hose reel composed of a wheel, a drum, and a handle having easy winding arrangement for a camel and a long pesticide hose is provided, and the engine-type pump installation unit and the hose reel installation unit have a certain thickness bending the metal pipe of the whole to be provided with one integral installation frame connected integrally; One handle is installed at the top of the center of gravity of the integrated installation frame to provide a hose reel combined pesticide sprayer characterized in that it is configured to be collectively performed in one operation when moving and installing the engine-type pump and hose. .

This hose reel combined pesticide sprayer has the advantage of easy movement and installation because the hose reel and the sprayer are integrally formed. However, the hose reel combined pesticide sprayer has a problem of causing soot, noise, and vibration in relation to adopting a small engine as a driving source.

More preferably, an inwardly concave collecting groove 42b is formed at the rear of the exhaust control hole made of the porous body, so that the chemical solution moving through the exhaust port is collected and passed through the exhaust control hole 42 through the collecting groove 42b. It penetrates and expands the sealing layer 42b overlaid on the exhaust control port 42.

Thus, the pump body 22c temporarily and automatically opens the exhaust port 41b to remain in the hose H during the process of inhaling the chemical liquid into the pump body 22c through the initial drive by the negative pressure prevention unit 40. A phenomenon in which suction of the chemical into the pump body 22c is inhibited due to excessive negative pressure generated on the side of the chemical outlet 22b by the air or the chemical is prevented.

In addition, when the chemical liquid is sucked into the pump body 22c and the chemical liquid is delivered at a high pressure through the chemical liquid discharge port 22b, the exhaust control port 42 exhausts the liquid while advancing to the end along the hollow pipe by the water pressure of the discharged chemical liquid. The port 41b is closed, and as a result, the delivered chemical is delivered to the hose H through the chemical delivery port 41a connected to the hose H.
