Description

Hose reel integrated electric agrochemical spray device}

The present invention relates to an electric pesticide spraying device integrated with a hose reel, and more specifically, to an electric pesticide spraying device integrated with a hose reel, which pumps the chemical solution stored in a medicine container at high pressure and sends it to the required spraying point through a hose wound around the hose reel and sprays it. It concerns pesticide spraying devices.

Pesticide spraying devices, which are usually used for the purpose of preventing disease in various crops or exterminating pests, consist 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 cabinet, and a medicine container.

Among them, the engine required to drive the pump often uses engines installed on various agricultural machines or uses electricity, but it lacks compatibility with agricultural machinery, the agricultural machinery itself that can be used is absent, or agricultural machinery is difficult to access, and electricity is used in areas. In areas where connection is difficult, an engine pump mounted with the engine is often used.

In addition, the pesticide hose is very long so that the pesticide pumped from the pump can be easily sprayed on crops located far away. Not only is there a high risk of entanglement if it is not organized, but it is also difficult to move due to its large size. It is common to use hose reels, which allow you to wind and unwind long hoses in an organized manner.

However, in the conventional configuration of the engine pump and hose reel for pesticide spraying, not only are they manufactured separately, but also the engine pump and hose reel must be moved and prepared individually when installing the pesticide spray device, which requires considerable labor and time. Not only was there a large waste factor, but there was also a significant waste factor in the manufacturing process and costs, and furthermore, there was considerable inconvenience in use and operation, and at the same time, there was an inconvenient disadvantage in that each product had to be purchased separately at the time of purchase.

Meanwhile, in order to overcome this problem, Republic of Korea Utility Model Publication No. 20-2010-0004153 has an engine-type pump installation part capable of fixed installation of an engine-type pump in which a small engine and a pump are integrated on one side, and another part of the engine-type installation part. On one side, there is a hose reel installation part for fixed installation of a hose reel consisting of a wheel, drum, and handle that facilitates wrapping and organizing long pesticide hoses, and the engine-type pump installation part and the hose reel installation part have a certain thickness. The metal pipes are bent to form an integrated installation frame in which the entire pipe is connected as one piece; We propose a hose reel combined pesticide sprayer, characterized in that a handle is installed at the top of the center of gravity of the integrated installation frame to enable movement and installation of the engine-type pump and hose in a single operation. .

This hose reel combined pesticide sprayer has the advantage of being easy to move and install because the hose reel and sprayer are integrated. However, the hose reel combined pesticide sprayer has the problem of causing smoke, noise, and vibration because it uses a small engine as a driving source.

An elevation handle 11a is integrally formed on the upper part of the frame body 11, and the hose reel 12 is a hose (H) wound in a winding space on both sides of a hollow winding shaft 12a having a winding space formed on the outer diameter. ) is configured to have a guard piece 12b disposed to prevent left and right separation, and a hose outlet 12c communicating with the hollow portion is formed through the hollow winding shaft 12a.

Accordingly, the starting end of the hose H wound in the winding space penetrates the hollow part of the hollow winding shaft 12a through the hose outlet 12c and is connected to the electric pump unit 20.

Preferably, the hollow winding shaft 12a constituting the hose reel 12 is rotatably fixed to the frame body 11 through an arch-shaped rotation bracket 15, and is provided through the winding handle 13. The rotating force rotates in one direction to wind the hose (H), and the hose (H) is pulled to rotate in the other direction to unfold the wound hose (H).

Meanwhile, the electric pump unit 20, which is formed to be stacked on the hose reel unit 10 and pumps the chemical liquid stored in the medicine container at high pressure and sends it out at high pressure along the hose H wound around the hose reel unit 10, is a medicine container. an electric pump (22) for high-pressure pumping and high-pressure delivery of the chemical liquid stored in; a battery 23 that applies current according to the driving of the electric pump 22; A controller 24 that controls whether or not stored current is supplied to the battery 23 of the electric pump 22; and a storage box 21 that provides a space for storing them.

The storage box 21 is formed with an entrance opening 21a having an opening and closing cover 21b, and a hollow tray 25 communicating with the entrance opening 21a is formed within the storage box 21. At (25), two or more batteries (23) are stacked and fixed.

At this time, the stacking surface of each battery 23 stacked in the hollow tray 25 and the inner wall of the hollow tray 25 in contact with the stacking surface of the battery 23 are adhered to each other in an inclined bevel structure as shown in FIG. 5.

It is fixed in a standardized way through (27).

Meanwhile, the electric pump 22 includes a chemical liquid inlet (22a) communicating with the medicine container through a suction pipe (P); a chemical liquid outlet (22b) through which high-pressure chemical liquid is delivered through a high-pressure pumping action; And a pump body (22c) that forcibly sucks the chemical liquid through the chemical liquid inlet (22a) through a high-pressure pumping action and delivers it at high pressure through the chemical liquid discharge port (22b).

Here, since the pump body 22c for high-pressure pumping of the chemical liquid is general-purpose, its detailed description will be omitted in this specification.

However, in this embodiment, negative pressure prevention units 30 and 40 with a unique exhaust control structure are disposed at the chemical discharge port 22b of the electric pump 22, and the initial electric power is prevented by the negative pressure prevention units 30 and 40. In the process of driving the pump 22 to introduce the chemical liquid stored in the medicine container into the pump body (22c), the chemical liquid or air remaining in the hose (H) is connected to the long hose (H) through the chemical liquid outlet ( The negative pressure is excessively formed on the side 22b), thereby preventing the delay or decrease in the flow of the chemical solution into the pump body 22c due to the negative pressure.

The negative pressure prevention portions 30 and 40 disposed at the chemical liquid discharge port 22b are chemical liquid discharge ports that connect the chemical liquid discharge port 22b and the hose H in mutual communication, as shown in FIGS. 4 and 6 to 7. Valve housings (31, 41) having (31a, 41a) and exhaust ports (31b, 41b) for communicating the chemical discharge port (22b) with the atmosphere, and an exhaust control port (31b, 41) for opening and closing the exhaust port (31b) 32, 42).

Preferably, the exhaust control ports 32 and 42 provided in the negative pressure prevention portions 30 and 40 are used to operate the pump body 22c during the initial operation, as shown in FIGS. 6A and 7A during the initial suction process of the chemical solution stored in the medicine container. Likewise, the exhaust ports (31b, 41b) are opened so that the air discharged from the pump body (22c) during the pumping process is discharged into the atmosphere, and when the chemical solution flows into the pump body (22c), it is exhausted as shown in FIGS. 6b and 7b. The ports (31b, 41b) are closed so that the chemical liquid discharged through the chemical liquid outlet (22b) passes through the chemical liquid discharge ports (31a, 41a) and is sent along the hose (H).

In this configuration, the pump body 22c is in the process of sucking the chemical liquid into the pump body 22c through the initial operation, and the chemical liquid discharge port 22b communicates with the atmosphere through the exhaust ports 31b and 41b, The occurrence of excessive negative pressure on the chemical discharge port (22b) due to the chemical liquid or air remaining in the hose (H) in communication with (22b) is prevented, and as a result, the chemical liquid is sucked into the pump body (22c) due to the excessive negative pressure. Deterioration of the phenomenon can be prevented.

In this way, if excessive negative pressure on the chemical discharge port (22b) is prevented through the open exhaust ports (31b, 41b), it is possible for the chemical liquid to be sucked into the pump body (22c) within a short period of time, and as a result, during initial operation, the chemical liquid discharge port (22b) is prevented. Excessive negative pressure is generated on the side 22b), so the chemical liquid is not sucked into the pump body (22c), thereby eliminating heat damage caused by long-time operation. In addition, the chemical liquid can be seen along the hose (H) through rapid suction and high-pressure pumping of the chemical liquid. It has the specificity of being able to transmit stably.

Here, the exhaust control unit 32, which sets the open/closed state of the exhaust port 31b, is composed of a ball valve, etc. as shown in FIG. 6, and can be configured to set the open/closed state of the exhaust port 31b through manual manipulation. do.

However, in this embodiment, a negative pressure prevention part 40 is proposed at the exhaust port 41b as shown in FIG. 7, so that the chemical solution can be pumped into the pump body 22c through the negative pressure prevention part 40 without any additional work by the operator. During the initial suction process, the exhaust port (41b) is temporarily opened, and when the suction of the chemical liquid into the pump body (22c) is completed, the exhaust port (41b) is automatically closed so that the sucked chemical liquid flows along the chemical discharge port (41a). Ensure that high pressure is discharged through the hose (H).

As shown in FIGS. 7A and 7B, the negative pressure prevention unit 40 includes a valve housing 41 having a chemical liquid delivery port 41a and an exhaust port 41b at the end; It includes an exhaust control port 42 that is disposed in a forward-retracting structure within the hollow pipe of the valve housing 41 and advances by the pressure of the chemical liquid discharged through the chemical liquid discharge port 22b and closes the exhaust port 41b.

More preferably, it further includes an opening force providing member 43 that pulls the exhaust control unit 42 through elasticity or magnetic force to open the exhaust port 41b closed by the exhaust control unit 42. do.

The opening force providing member 43 may be a traction spring that pulls the exhaust control member 42 along the hollow pipe, or a permanent magnet that pulls the exhaust control member 42 along the hollow pipe through a magnetic coupling force. In the present invention, for example, an opening force providing member 43 made of a permanent magnet is disposed to pull the exhaust control member 42 made of a ferromagnetic material through magnetic coupling force.

Therefore, as shown in FIG. 7A, the negative pressure prevention unit 40 is operated through the exhaust port 41b by the exhaust control port 42 when the pump body 22c is initially driven and the chemical liquid is not discharged through the chemical liquid discharge port 22b. remains open, and when the chemical liquid is discharged through the chemical liquid outlet (22b), the exhaust control port (42) advances outward due to the water pressure of the discharged chemical liquid and closes the exhaust port (41b), as shown in FIG. 7b. .

In particular, as shown in Figure 7b, the exhaust control port 42 surrounded by the sealing layer 42b is composed of a porous body with a plurality of permeable holes, and the chemical liquid moving along the exhaust port 41b is discharged from the exhaust control port made of a porous body. By penetrating the permeable holes of (42) and expanding the sealing layer (42b) overlaid on the outer wall of the exhaust control port (42), a more stable closed state of the exhaust port (41b) by the exhaust control unit (42) is formed. .

More preferably, the rear of the exhaust control port 42 made of the porous body is formed with an inwardly recessed water collection groove 42a, so that the chemical liquid moving through the exhaust port 41b is collected and collected through the water collection groove 42a. It passes through the exhaust control port 42 and expands the sealing layer 42b overlying the exhaust control port 42.

Therefore, in the process of sucking the chemical liquid into the pump body (22c) through the initial operation by the negative pressure prevention unit 40, the pump body (22c) temporarily automatically opens the exhaust port (41b) so that the liquid remains in the hose (H). Prevents the phenomenon of excessive negative pressure being generated on the chemical discharge port (22b) by the exposed air or chemical liquid, thereby impeding suction of the chemical liquid into the pump body (22c).

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