Description

Chemical liquid spraying equipment {EQUIPMENT FOR SPRAYING AGRICULTURAL CHEMICALS}

The present invention relates to the field of equipment for spraying agricultural chemicals to crops, and more particularly, in a state in which a chemical liquid injection module is installed so that sag does not occur in a light weight and flowable annular rope. The chemical injection module reciprocates between the furrows and furrows planted so that tall crops form rows, and injects the chemicals into the crops, and minimizes the length of the chemical hoses supplying the chemicals to the chemical injection module. It relates to a chemical liquid injection facility.

In recent years, the development of construction technology for glass greenhouses and plastic houses has allowed the cultivation and sale of crops that could be grown only in certain seasons.

Accordingly, in recent years, cultivation of tall crops such as cucumbers and tall flowers in large glass houses and large plastic houses with very high cultivation area and ceiling height has also become possible.

These tall crops are grown and harvested in rows of furrows arranged in rows within the plastic house.

However, when the crops are tall, it is very difficult to uniformly spray the chemicals to prevent pests and pests, and the chemicals require considerable labor.

In view of such a problem, recently, a metal rail is installed parallel to the furrow in a ceiling of a glass greenhouse or a plastic house corresponding to the furrow and the furrow in which the tall crops are grown, and a power motor moved along the metal rail, Install an electric cable for supplying power to the power motor, and a chemical hose drawn by the power motor.

In addition, a chemical liquid injection facility has been developed to install a chemical liquid injection module having a vertical bar shape in a vertical direction from a power motor so that chemical liquid is uniformly sprayed on crops grown in both furrows.

However, such a conventional chemical liquid spraying equipment is expensive to install a chemical liquid in the glass greenhouse or a vinyl house, the power motor to pull the chemical strings for each rail is complex, the equipment required for chemical spraying complex, difficult to manufacture, The installation cost has an excessive problem.

Moreover, most large glass greenhouses or vinyl houses have dozens of furrows. However, the above-described conventional chemical liquid injection device has to be installed every two furrows, so when applied to a large glass greenhouse or vinyl house having a large number of furrows, there is a problem that excessive facility investment.

In addition, in the conventional chemical liquid injection facility, the chemical liquid to be supplied to the chemical liquid injection module is supplied by the fluid hose. In this case, the fluid hose must have a length enough to reach the other end from one end of the metal bar to inject the chemical liquid from one end of the furrow to the other end of the furrow.

In this case, as the area of the glass greenhouse or the vinyl house is very large, and the length of the furrow is longer, the pressure of the chemical liquid supplied to the chemical liquid injection module may also be very high so that the chemical liquid may be injected from the chemical liquid injection module at a predetermined pressure.

Such a structure creates a problem in that the chemical liquid has to go through a process of making a high pressure using a high pressure pump.

Accordingly, the present invention has been made in view of such a conventional problem, and an object of the present invention is to install a flexible rope in a house that provides a cultivation space for crops, such as a glass greenhouse or a vinyl house, and to prevent sagging in the flexible rope. The chemical liquid injection module is installed so that the chemical liquid can be supplied to the crops from the chemical liquid injection module.

Another object of the present invention is to drive the chemical liquid injection module by one power source so that the chemical liquid can be sprayed at least simultaneously over the entire house.

Still another object of the present invention is to allow the chemical liquid to be supplied to the entire furrow with a length of 1/2 the length of the chemical liquid hose supplying the chemical liquid to the chemical liquid injection module.

Or fixed by welding.

As such, the rope support roller 330 is installed on the bottom surface of the mounting plate 320 installed in the horizontal bar 340 for rigid reinforcement.

Rope support roller 330 is used two kinds of rollers having different forms, in the present invention will be defined as the first support rollers 332, 334 and the second support roller 336.

Specifically, the first support rollers 332 and 334 have a cylindrical shape with no change in diameter, and the second support roller 336 has a shape having a trapezoidal shape in which a diameter increases from an upper surface to a lower surface.

At this time, in the present invention, as an embodiment, two first support rollers 332 and 334 are used, and one second support roller 336 is used.

More specifically, where the annular rope 100 passes through the bottom of the mounting plate 320, first support rollers 332 and 334 spaced apart from each other by a predetermined interval are installed through the rotation shaft 338, and the first support rollers 332 and 334. ), A second support roller 336 is installed via the rotation shaft 338.

The rope support roller 330 having such a configuration is coupled to the annular rope 100 to prevent sagging of the annular rope 100.

That is, since the first support rollers 332 and 334 and the second support rollers 336 support the annular rope 100, the annular rope 100 is not separated from the first and second support rollers 332, 334 and 336. Since they all have a cylindrical shape, it is easy to rotate and the connecting rod 520 of the chemical liquid injection apparatus 500 to be described later can be easily passed.

Specifically, the annular rope 100 subjected to a predetermined tension is first installed so as to pass between the first support roller 332 and the second support roller 336, and then the first support adjacent to the second support roller 336 again. It is installed to pass through the roller 334.

As a result, the annular rope 100 is seated on the inclined surface of the second support roller 336 and is supported by the first support rollers 332 and 334 so as not to be separated from the second support roller 336.

At this time, it is important to precisely adjust the interval between the first and second support rollers 332, 334, 336 so that the annular rope 100 is not separated from the second support roller 336 to the outside.

At this time, the rope sag prevention device 350 shown in Figure 2 is installed at a predetermined interval, for example, 4m intervals to prevent the sag of the annular rope 100 occurs.

In the state where the deflection of the annular rope 100 is prevented by the rope deflection prevention device 350, the chemical liquid injection device 500 is installed in the annular rope 100.

The chemical liquid injector 500 includes a support rod 510, a connection rod 520, and a chemical liquid injector unit 530. In addition to this configuration, the chemical liquid injector 500 may have any configuration for uniformly injecting the chemical liquid.

The other end of the connecting rod 520 is coupled to the annular rope 100.

On the other hand, the support rod 510 is provided with a plurality of chemical liquid injection unit 530 for receiving the chemical liquid from the chemical liquid supply device 600 to be described later.

The chemical liquid injection unit 530 is composed of a chemical liquid supply pipe (not shown) and a chemical liquid injection nozzle 532.

As such, the chemical liquid supply device 600 is connected to the chemical liquid supply pipe of the chemical liquid injection unit 530 in order to supply the chemical liquid to the crop 1 through the chemical liquid injection unit 530.

The chemical liquid supply device 600 includes a chemical liquid tank 610, a chemical liquid pump 620 for remotely transporting the chemical liquid at a predetermined pressure, and a chemical liquid transport pipe 630.

Specifically, when the chemical injection device 500 is detected by the first detection sensor 710, the current rotation direction of the forward and reverse rotation motor 240 is reversed, and the chemical injection device is changed by the second detection sensor 720. If 500 is detected, the current rotation direction of the forward and reverse rotation motor 240 is also reversed.

Specifically, referring to FIG. 3, when the chemical liquid injector 500 currently proceeds from the position of B to the direction A, the rotation shaft 230 of the forward and reverse rotation motor 240 rotates clockwise, but the forward and reverse rotation motor When the 240 reaches the position A, and the first detection sensor 710 detects the chemical liquid injector 500, the control unit counterclockwise rotates the rotational axis 230 of the forward and reverse rotation motor 240. The chemical liquid injection device 500 passes through B to reach C again.

Hereinafter, with reference to the accompanying Figure 4 will be described a chemical liquid injection method by the chemical liquid injection facility according to an embodiment of the present invention.

First, when the chemical liquid supply device 500 starts to be operated by the control unit, the chemical liquid is supplied from the liquid chemical supply device 600 to the chemical liquid injection device 500 and starts to be sprayed onto the crop 1 (step 10). )
