Description

[0001] The present invention relates to an automatic water supply device capable of moving along three-dimensional coordinates,

The present invention relates to an automatic water feeder capable of moving along three-dimensional coordinates, and more particularly, to an automatic water feeder capable of moving along three-dimensional coordinates through an automatic machine capable of managing plants within a limited area, The present invention relates to an automatic water supply device capable of moving along three-dimensional coordinates so that plants that can be left untreated can receive water uniformly by giving water.

As the industry develops and the population grows, agricultural land and clean areas are decreasing due to the expansion of various factory facilities and housing construction. In particular, the use of chemical fertilizers has made the farming area of farms inefficient, Growing of agricultural products and various kinds of plants is getting difficult.

Moreover, the plants that grow in these environments are not growing well, and when pollutants are accumulated in plants and supplied to humans, they cause various diseases. In particular, in the case of vegetables that are consumed directly without processing, such as sprout vegetables used for salads, there is a growing interest in the harmfulness of the residual pesticides, and the desire to directly grow and eat the vegetables necessary for the diet is increasing .

However, in order to grow vegetables, it is necessary to secure the necessary land for cultivation and considerable human effort is required. In addition, it is very difficult to cultivate the vegetables to be consumed in a general household because it takes a considerable period of time until the planting and harvesting of vegetables is not performed in a short time.

Recently, hydroponic cultivation has been considered as an alternative to growing vegetables directly at home. Hydroponic cultivation is to directly supply the culture medium containing various growth promoting agents to the roots of the plants to artificially accelerate the growth rate of the plants, so that a large amount of yield can be obtained in a short period of time as compared with general cultivation.

In order to cultivate plants such as plants and vegetables grown in pollen or flower beds at home through hydroponic cultivation, the supply amount and supply cycle of water should be varied in accordance with the cultivation characteristics of the plant. In other words, depending on the type of plant, when the water is supplied at a low rate, the stem or the leaf is dried, and when the water is supplied in an excess amount, the root rot will occur. .

In particular, when a plant is grown using a flowerpot or a flower bed in a general household, there are many difficulties in supplying a certain amount of water to a plant which is difficult to cultivate, such as lack of cultivation or egg production, It is impossible to grow smoothly as the water is supplied to a large amount or the water can not be supplied for a certain period of time.

Thus, plants grow while absorbing moisture in the soil through capillary action in the roots at the roots, but in the case of plants grown in the indoor garden of a veranda of an apartment or house, Water should be given, especially when the house is vacated for a few days, such as during the summer holidays. Indoor gardens and pollen plants can not absorb enough moisture, such as plants growing in the soil, and the plants are not left unattended if they do not supply water for a few days Can be.

Accordingly, there is a growing need for an automatic water supply system or a system therefor in recent years. Especially, it is considered that the need for a system in which the water supply is appropriately distributed according to various plants and is automatically selected and supplied according to the environment change is more urgent.

Hereinafter, the present invention will be described in detail with reference to the accompanying drawings. The conventional automatic water supply technology is advantageous in that it is cheap and can be installed and recovered easily. However, since it is fixedly installed on the floor or ceiling of the cultivating area where plants are grown, It is difficult to fine-tune such as water injection amount and injection direction, and it is difficult to finely control the amount of water such as the amount of water sprayed within a fixed radius, There are problems that reduce production speed and yield.

Unlike the prior art, the present invention supplies the water to the plants that can be left unattended by supplying the water by operating the pump at the place where the water is moved along the automated toolpath after the power is supplied by the software. And to receive them.

As shown in FIG. 1, an automatic water supply device movable along three-dimensional coordinates according to the present invention includes a H-gantry in XY motion and a base fixed to a 3D printer A plurality of guide rails provided in the front half of the main body and having a plurality of guide rails designed with an aluminum profile as an axis and having brackets movable along the guide rails, Which comprises a hydroplane capable of moving along a plurality of guide rails and brackets, a moving device composed of two stepper motors, and a PVC pipe connected to the moving device and configured to supply water while moving along the guide rail and the bracket, . ≪ / RTI >

The main body of the apparatus is composed of an H-gantry that is horizontally disposed with the bottom surface and performs X-Y motion, and a base fixing plate that is output to a 3D printer. Gantry XY motion using two stepper motors, and it is possible to install after installing and expanding the module, so it is possible to install after installing the machine. Installation, disassembly, and additional functions can be carried out easily. Also, in the case of the fixing table, since the stand output from the 3D printer is used, it is easy to replace the module according to the crop height required for cultivation. This makes it easy to carry out various repairs and inspections without being limited by space for installation and use of the apparatus.

In the first half of the main body, a plurality of guide rails designed with the aluminum profile as an axis are formed and a bracket movable along the guide rails. The guide rails are designed to move axially using a profile and to use a profile that can be screwed into the middle of any aluminum profile. The designed aluminum frame is freely movable within the limited area of 420 * 420mm. In addition, the aluminum frame moves together with the bracket to control the tolerance between the motors.

A hydro pump and two stepper motors are formed at one end of the guide rail and the bracket. The two stepper motors give the voltage of the DC electrode by the hydro pump, move together and move the water injector to the predetermined position to supply water exactly where desired. Since the mobile device moves freely in a limited area, it is possible to use it without limitation in the cultivation space, thus making it possible to perform watering work more easily and fast (FIG. 2). The stepper motor of the mobile device is a motor for converting electric pulse signals into angular displacement or linear displacement. When the stepper drive receives a pulse signal, it drives the stepper motor to rotate at a fixed angle in the set direction called the "step angle", and its rotation runs one step at a fixed angle, one step at a time. It is possible to control the angular displacement amount so as to achieve the purpose of accurately determining the position by controlling the number of pulses and to control the speed and acceleration of the motor rotation so as to achieve the purpose of speed control by controlling the pulse frequency. The stepper motor is often used to drive the pointer of the indicator, and therefore it is required that the output shaft of the stepper motor be rotated not only in the clockwise direction but also in the counterclockwise direction. Therefore, in the present invention, the position accuracy of the entire apparatus is increased by using two stepper motors.

A water injection device is connected to the moving device. The water supply device of the water injection device is configured to receive water from a general water container because the device size of the present invention is not large. The water injection device is made of a PVC pipe so that a suitable amount of water (water pressure) can flow. The PVC pipe connected to the water bucket can move along the guide rails and brackets together with the moving device consisting of the hydro pump and the two stepper motors, so that water can be supplied evenly to the plants in the predetermined position. This results in an increase in plant production rate and productivity since the number of plants that are left untreated and become rotten or disappear is reduced (FIG. 3).

The device for controlling the movement of the automatic water supply device movable along the three-dimensional coordinates is set to 200 microsteps so that the device can be controlled without imposing a strain on the machine. When the stepper motor is used as a microstep, the current waveform can be precisely driven by a sinusoidal electric angle.

In general, most of the devices use a power supply in addition to the driver, which is disadvantageous in that it is difficult to supply normal current during high-speed operation. When a microstep driver with a built-in busser circuit is used, high torque and high-speed operation are possible (FIG. 4).

Since the bracket and the stepper motor driver that can be moved along the guide rail used in the apparatus of the present invention use a modular product, they can be easily replaced even if an overcurrent occurs (FIG. 5).

Hereinafter, embodiments will be described in detail so as to effectively utilize an automatic water supply device capable of moving along three-dimensional coordinates configured according to the above method, for supplying water.

< Example >

The automatic feeding device that can move along the three-dimensional coordinate according to the present invention is used to automatically feed the water while moving in accordance with the three-dimensional coordinates set in the simulated field that can contain plants of 350 mm in length and width (Fig. 6). After the power is simply supplied, the hydro pump is operated at a place along the guide rails and the brackets that form the H-gantry of the XY motion using two stepper motors by software automated toolpath, By supplying water to the plants automatically from the spraying device, the water can be supplied to the plants evenly.

According to the present invention, the automatic water dispenser capable of moving along three-dimensional coordinates automatically supplies water to the plants in the area as the water supply device moves along the three-dimensional coordinates, thereby increasing the production speed and production amount of the plant. It is easy to separate and install and disassemble the machine and install the additional functions. It is limited in the frame. Therefore, it can be used in a small space such as hydroponic cultivation facility or house veranda or spraying pesticide It is possible to use it in industry.
