Description

Sprout growing apparatus {Sprout growing apparatus}

The present invention relates to a sprout cultivation device that places seeds inside a rotating drum and then grows the seeds by spraying water while rotating the rotating drum. More specifically, the internal structure of the rotating drum is dramatically improved. This relates to a sprout cultivation device that allows cultivation to occur while the seeds or germinating seeds move in a sliding manner rather than falling freely vertically even when the rotating drum rotates.

In general, sprout vegetables refer to vegetables that are grown from seeds that germinate to less than 10 cm in size with only water. Bean sprouts, bean sprouts, radish sprouts, alfalfa sprouts, etc. are already being cultivated.

Cultivation methods for these sprout vegetables are roughly divided into small-scale cultivation methods and large-scale cultivation methods.

The small amount of cultivation means includes placing seeds in a basket or the like, covering them with a light-blocking cover, periodically supplying water to germinate the seeds, and placing cotton or sponge in a seedling box to a certain thickness. There is a known method of cultivating by spreading seeds on top of the ground and supplying water.

In addition, as a means of mass cultivation, a means of spreading topsoil and sand or soil evenly inside a greenhouse, then densely scattering seeds on top, and cultivating while supplying water is known.

The above-mentioned conventional sprout cultivation means are means that have been classically used since ancient times, and although water must be supplied periodically to the sown seeds, the cultivation speed is lowered or the growth speed is not constant due to the failure to maintain a constant water supply cycle. , when the internal temperature rose to a high temperature, seeds often rotted.

And the above-mentioned cultivation methods are not cultivation methods for commercialization, but are intended for simple cultivation and consumption in each home.

These sprout cultivation methods not only require a lot of labor costs as all work is done manually, but are also disadvantageous for mass production, so the development of a device for automatically growing sprouts was required.

Figure 1 is a perspective view showing an exploded front of a conventional sprout cultivation device, Figure 2 is a perspective view showing an exploded view of the back of a conventional sprout cultivation device, and Figure 3 is a perspective view of the assembled state of Figure 1, and the sprout cultivator 100 is inside. It is provided in a cylindrical shape to contain seeds, and a door 112 that can be opened and closed is installed on one side, a rotating drum 110 with a penetrating blower 114 is installed on the other side, and the rotating drum 110 is fixed. , a rail member 120 having a ring-shaped cross-section provided along the outer peripheral surface of the case to guide the rotation of the rotating drum, and a drive motor unit 130 that transmits rotational force to the drive shaft 132 fixed to the other side of the rotating drum. It consists of a support 160 having a rotation support 140 into which a roller 142 that contacts the rail member and rotates like a rotating drum is inserted.

The rotating drum 110 has broccoli, red radish, kohlrabi, Chinese cabbage, rapeseed, multi-colored vegetables, barley, bok choy, mustard, alfalfa, clover, radish, red cabbage, red beans, wheat, barley, turnip, chive, kale, It is a container that can contain safflower or flax seeds, and is a cylindrical container.

An openable door 112 is installed on one side of the rotating drum 110, and a blowing hole 114 is formed on the other side to supply outside air to the inside by a blowing fan 114', and the door ( In 112), another vent 116 is formed to discharge moist air.

The rotating drum 110 is divided into four compartment case members 110' to form a cultivation room, and a water pump (not shown) is installed inside each compartment case member 110' at predetermined intervals. A plurality of nozzles 134 that spray water according to driving are arranged.

Therefore, with the door 112 open, seeds to be cultivated are placed in each of the four divided spaces, and then the opened door 112 is closed, the water pump is driven, and the rotary drum 110 is rotated at the same time, thereby forming a plurality of seeds. As a certain amount of water is sprayed through the nozzle 134, the cylindrical rotating drum 110 rotates, thereby cultivating seeds.

(Patent Document 0005) Republic of Korea Registered Patent 10-2227602 (announced on March 12, 2021)

However, this sprout cultivation device had several problems as follows.

First, one rotating drum in the shape of a cylinder is installed on the drive shaft, and the closed space is divided into four parts by a partition case member inside the closed space, so that when the position of the closed space reaches a certain angle, the germinating seeds are vertical due to the tilt. As a result, the free-fall movement section becomes longer, and as a result, the germinating seeds fall at the same time and the germinated sprouts collide with each other, resulting in a fatal defect in which the germ and embryo are separated.

Second, in the process of planting seeds in each closed space, if the temperature at any one location rises due to seed germination or gas is generated due to the growth environment of the sprouts, even if an outlet is formed, the air is discharged through the outlet. As the amount of (fungal spores generated by high temperature, gas, decay, etc.) is limited, it cannot be quickly eliminated, and the sprayed water is transferred to other cultivation rooms by capillary action through the gap between the compartment case member and the rotating drum, thereby preventing the remaining normal growth. It also contaminates the sprouts.

Third, the inner bottom of the cultivation room is angled in a triangular shape, so when the volume of the sprouts increases during the cultivation process, pressure is applied to the sprouts in this area due to the weight of the sprouts and water at the top, so the sprouts are damaged or their quality deteriorates. In addition, problems occurred in hygiene and safety management as the harvest was not thoroughly cleaned during the cleaning process after harvesting.

In particular, if water (coolant) cannot easily reach the sprouts pressed to the bottom, the temperature rises due to friction of the sprouts, which eventually causes them to rot, resulting in a decrease in the quality of the sprouts.

Fourth, an exhaust fan that discharges gases generated by the sprout growth environment inside the rotating drum to the outside is installed on the base that supports the rotating drum, so that the gas generated inside the rotating drum can be quickly discharged to the outside. Because it cannot be used, it also contaminates normal buds.

Fifth, after growing sprouts in four independent cultivation rooms, the sprouts had to be taken out manually with the door open, which reduces the workability of taking out the sprouts.

Sixth, water sprayed onto the germinating seeds through a nozzle inside the rotating drum flows down through the gap in the door and is discarded, resulting in increased water usage.

The present invention was devised to solve such problems in the prior art. By improving the internal structure of the rotating drum, the seeds or germinating seeds do not fall freely vertically and are repeated in the process of placing seeds inside the rotating drum and germinating them. The purpose is to prevent the phenomenon of separation of the germinating germ and embryo by allowing cultivation to be carried out with cloud movement.

Another object of the present invention is to install a plurality of exhaust fans directly on the rear door so that gases generated during the cultivation of sprouts can be quickly discharged to the outside.

Another object of the present invention is to dramatically improve the internal structure so that the cultivation spaces of sprouts grown in the rotating drum are communicated with each other to form a shared space, so that even if the internal temperature of the rotating drum rises or gas is generated due to seed germination, The goal is to quickly disperse polluted air into a shared space to prevent it from spreading to other sprouts being grown.

Another object of the present invention is to rotatably install the movable frame on which the rotating drum is installed, so that after the cultivation of sprouts is completed, the movable frame on which the rotating drum is installed is tilted at a predetermined angle and the rotation direction of the rotating drum is rotated in the opposite direction. The purpose is to automatically discharge the grown sprouts from the rotating drum as the switch is switched.

According to an aspect of the present invention for achieving the above object, a rail member is fixed to the outer peripheral surface of a cylindrical rotating drum, and the rail member is placed on a roller installed on a support so that the rotating drum rotates by driving the first drive motor unit. In a sprout cultivation device that sprays water toward the seed through a nozzle during cultivation, one end of a plurality of seating members each having a seating surface on which the seed is placed and grown is fixed inside a rotating drum having a rounded inner peripheral surface. The other end of each holding member forms a space spaced apart from the inner surface of the rotating drum, and the center of the rotating drum is a shared space that communicates with each other, so that the internal environment of the rotating drum is maintained uniformly. A sprout cultivation device is provided.

The present invention has the following advantages over the prior art.

First, a certain amount of seeds are placed on each seating surface formed on the rotating drum, and then water is sprayed through a nozzle, and as the rotating drum rotates, the seeds or germinating seeds slide along the placing surface and the inner circumferential surface of the rotating drum, allowing for cultivation. This prevents the separation of the germinating germ and embryo.

Second, one end of the plurality of placing members is fixed to the inside of the rotating drum so that a shared space is formed inside the rotating drum, and the other end is configured to form a space, so that some of the germinating seeds in the placing member are transported to the rotating drum through the space. When the seed exits along the inner circumferential surface and rotates to the other side, it slides along the inner circumferential surface again and flows into the inside of the holding member, thereby shortening the movement section of the seed, thereby preventing the phenomenon of separation of the germinating germ and embryo. It is prevented.

Third, since a plurality of exhaust fans are installed on the rear door, gases generated during seed cultivation can be quickly discharged to the outside, thereby maintaining good seed growth.

Fourth, in the process of placing seeds in each holding member and cultivating them, even if the temperature in one place rises due to the germination of the seeds or gases are generated due to the growth environment of the sprouts, the entire inside of the rotating drum is made up of a shared space that is open. In addition, first and second ventilation/drainage holes are formed in the door to communicate with the space of each holding member, so this problem can be resolved, allowing sprouts to be grown in a healthy state.

Fifth, the cross section of the placement member where the sprouts are grown is in a "C" shape, so even if the volume of the sprouts increases during the cultivation process, pressure is applied uniformly throughout, thereby improving the quality of the sprouts.

Sixth, after cultivating sprouts on the rotating drum, by tilting the rotating drum at a predetermined angle and rotating the rotating drum in the reverse direction, the grown sprouts are automatically pulled out of the holding member, allowing the sprouts to be taken out automatically.

Seventh, the amount of water used can be significantly reduced because used water is returned to the water tank, sterilized, purified, and reused.

An embodiment of the present invention includes a cylindrical rotating drum 10, A seating member 20 is provided inside the rotating drum to be divided into a plurality of rounded curves and has a seating surface 20a on which the seeds are placed, and can be opened and closed at the front and rear of the rotating drum 10. Installed front and rear doors (30) (40), a plurality of nozzles (50) installed on the rotating drum to spray water on the growing seeds or sprouts, and at least one rail fixed to the outer peripheral surface of the rotating drum A member 60, a support 70 on which the rotary drum is rotatably placed, a first drive motor 80 that rotates the roller 61 to rotate the rotary drum 10, and the rotary drum It is composed of a second drive motor 81 that tilts it at a predetermined angle.

FIG. 7 is an exploded perspective view showing the main parts of another embodiment of the present invention, FIG. 8 is a perspective view showing a part of another embodiment of the present invention in cross section, and FIG. 9 is a front view of FIG. 8, showing a cylindrical rotating drum 10 and the A plurality of seating members 20 installed inside the rotating drum on which seeds are placed and grown, front and rear doors 30 and 40 installed to be openable and closed on the front and rear sides of the rotating drum 10, and the rotating drum 10. A support plate 23 that simultaneously supports a plurality of seating members 20 installed inside the drum 10 on the rotating drum, and a plurality of nozzles installed in the rotating drum to spray water on the seeds or sprouts being cultivated ( 50, at least one rail member 60 fixed to the outer peripheral surface of the rotary drum, a support 70 on which the rotary drum is rotatably placed, and the roller 61 is rotated to rotate the rotary drum 10 ) is composed of a first drive motor 80 that rotates the drum, and a second drive motor 81 that tilts the rotating drum at a predetermined angle.

The rotating drum 10 is made of a cylindrical cylinder type as shown in FIGS. 4 and 8, and seeds being cultivated are placed on the inner peripheral surface 10a or a portion close to the inner peripheral surface of the rotating drum 10 (not shown). ) Or, a plurality of nozzles 50 that spray water on the sprouts are fixedly installed, and at least one rail member 60 is fixed to the outer peripheral surface of the rotating drum 10.

The rotating drum 10 is formed with a plurality of long holes 11 having a ventilation/drainage function so as to be located at the top of each placing member 20, as shown in FIG. 8. Seeds or seeds are distributed outside each long hole through the long holes. A mesh net (12) that prevents the sprouts from coming out is fixed.

4 to 7 showing an embodiment of the present invention, the placing surface 10a on which the seeds are placed inside the rotating drum 10 is formed over the entire surface of the placing member 10 to form a closed space. In FIGS. 8 to 10 shown as another example, a plurality of seating members 20 having a seating surface 10a on which seeds to be grown are installed inside the rotating member 10, and at one end are placed inside the rotating drum 10. The fixing piece 21 is formed integrally, and the other end is formed short so as to be spaced apart from the inner surface of the rotating drum 10 to form a space 12, so that the inside of the rotating drum 10 is connected to each other as shown in FIG. 10. It is designed to have a shared space (S) that communicates.

The reason why the inside of the rotating drum 10 has a shared space S that communicates with each other is to ensure that the internal environment (temperature, humidity, gas, etc.) of the rotating drum 10 is maintained uniformly.

The shape of the seating surface 20a formed on the seating member 20 may be any shape as long as the seeds to be cultivated are placed on the upper surface and have a structure that slides without falling freely when the rotating drum 10 rotates. However, each shape of the present invention In the example, the cross section is shown in a “C” shape.

In another embodiment of the present invention, the gap in the space 22 formed between the placing member 20 and the rotating drum 10 is different because the length of the cultivated sprout varies depending on the type of seed to be cultivated. It is understandable that it can be applied.

The front door 30, which is installed to be openable and closed on the front of the rotating drum 10, has a plurality of first ventilation/drainage holes 31 formed along the edge as shown in FIG. 12, and the inside of the seating member 20 is provided. A second ventilation/drainage hole 32 is formed to be located in the rear door 40, and an exhaust hole (not shown) is provided to discharge the gas generated during cultivation of sprouts to the outside as shown in FIGS. 4 and 8. ) An exhaust fan 41 is installed to be located outside of the.

At this time, electricity is stably supplied to each exhaust fan 41 installed on the rear door 40 through a known rotary electric supply device (not shown) installed on the hollow shaft 15, so that the rotary drum 10 Even if it rotates, the exhaust fan 41 operates.

The front and rear doors 30 and 40 installed on the front and rear sides of the rotating drum 10 are respectively configured to open and close by known clamping means (not shown).

Support plates 23 as shown in FIG. 13 are fixed to both ends of the rotating drum 10 to firmly maintain the plurality of seating members 20, one end of which is fixedly installed inside the rotating drum 10.

As shown in FIG. 11A, the support 70 is divided into a fixed support 71 and a movable support 72 on which the rotary drum 10 is rotatably installed, so that the movable support 72 is the fixed support 71. It is installed to be rotatable about an axis 73.

A pair of rollers 61 on which the rail member 60 rests are installed on the upper surface of the movable support 72, and a first drive motor 80 is installed on one of the rollers 61 so that the first drive motor 80 is installed on the first drive motor 80. As the roller 61 rotates due to the drive motor 80, the rotating drum 10 rotates on the movable support 72.

The first drive motor 80 rotates the rotary drum 10 clockwise when cultivating sprouts inside the rotary drum 10, and after the sprout cultivation is completed, A step motor that rotates counterclockwise was applied to automatically extract the sprouts.

4 and 7 showing an embodiment of the present invention, a water tank 100 is provided at the lower part of the rotating drum 10 to recover water sprayed through the nozzle 50 for cultivation of seeds, and the water A filter (not shown) is installed inside the tank 100 for sterilization and purification of recovered water.

In another embodiment of the present invention, another auxiliary roller 62 is further applied to the upper part of the movable support 72 so that the rotating drum 10 can rotate more stably.

In addition, the second drive motor 81 is fixed to the fixed support 71, and as the second drive motor 81 drives, the movable support 72 is centered on the axis 73 by the cam means 90. As it rotates, the rotating drum 10 installed on the movable support 72 is tilted at a predetermined angle.

In another embodiment of the present invention, the cam means 90 is provided with a cam pin 91a and is fixed to the link 91 fixed to the axis of the second drive motor 81 and the bottom of the movable support 72. Although the cam 92 is formed with a long hole 92a into which the cam pin 91a is inserted, it is understandable that it can be applied in various forms by experts in the field.

The operation of the present invention is explained as follows.

First, with the front door 30 open, a certain amount of seeds to be grown are placed on the upper surface of the seating surface 20a of each placement member 20 and the front door 30 is closed.

In this state, when power is applied to the first drive motor 80 while spraying a certain amount of water intermittently for a set time through the plurality of nozzles 50 installed on the rotating drum 10, the roller 61 and the auxiliary roller 62 ) rotates, so the rotating drum 10 installed on the movable support 72 rotates in the forward direction.

As described above, when the rotary drum 10 rotates in the forward direction, in Figures 4 to 8 shown as an embodiment of the present invention, the seeds placed on the placing surface 20a slide along the rounded curve of the placing surface, and when placed, they slide. Since cultivation is carried out by sliding on the inner peripheral surface (10a) of the rotating drum (10) connected to (20a), the impact on the seed is minimized, thereby preventing the separation of the germinating germ and embryo from the seed. It can be prevented in advance.

However, in Figures 8 to 10 shown as another embodiment of the present invention, the seeds to be cultivated are placed on the seating surface 20a of the seating member 20, and then the rotary drum 10 is rotated while spraying water through the nozzle 50. When the seeds are grown while sliding along the placing surface 20a of the placing member 20 and the inner peripheral surface 10a of the rotating drum 10, one end of the placing member 20 is located on the inner peripheral surface of the rotating drum 10 ( Since it is spaced apart from 10a) to form a space 22, the inside of the rotating drum 10 takes the form of a shared space (S) that communicates with each other, so the process of growing sprouts in one or more placing members 20 Even if the temperature rises due to the germination of seeds or gas is generated due to the growth environment of the sprouts, the problem of the internal temperature of the rotating drum 10 rising locally or the gas stagnating due to the shared space (S) is resolved. It has the advantage of being able to do so.

When growing sprouts on the placing member 20 while rotating the rotating drum 10, some seeds or sprouts are formed at one end of the placing member 20 in the right section of the rotating drum 10 shown in FIG. 10. Even if it escapes through the space 22, it flows back into the inner peripheral surface 10a of the rotating drum 10 through the space 22 in the left section. In the present invention, the seeds or sprouts escape from the placing member 20. Alternatively, when introduced, it slides in a short section along the inner peripheral surface (10a) of the rotating drum (10), thereby minimizing the phenomenon of germinated sprouts colliding with each other, thus preventing separation of the germ from the germ. .

As described above, when growing by spraying water toward the seeds or sprouts through the nozzle 50, the sprayed water is drained through the first and second ventilation/drainage holes 31 and 32 formed in the front door 30. In addition, some of the water is drained through the long hole 11 and returned to the water tank 100 installed at the bottom of the rotating drum 10, where it is filtered and sterilized by a filter (not shown) and returned. Since it is supplied to the nozzle 50 through the pipe 101, it becomes possible to grow sprouts even while using minimal water.

After the cultivation of sprouts is completed for a certain period of time while rotating the rotary drum 10, the driving of the first driving motor 80 is temporarily stopped under the control of a control unit (not shown) and the second driving motor is simultaneously stopped. (81) is driven.

That is, when the second drive motor 81 drives to raise the link 91, the cam pin 91a formed integrally with the link 90 moves along the long hole 92a of the cam 92 to form a movable support 72. ) is rotated around the axis 73 as shown in Figure 11b, so the rotating drum 10 installed on the movable support 72 is tilted at a predetermined angle.

When the rotating drum 10 is tilted at a predetermined angle as shown in FIG. 11b, the clamping state of the front door 30 is released and the first drive motor 80 is restarted in the reverse direction by the control unit, thereby growing the sprouts. Since they sequentially come out along the seating surface 20a and the inner peripheral surface 10a, the grown sprouts are automatically placed in a container (not shown).

After all the grown sprouts are taken out from the rotary drum 10, the inside of the rotary drum 10 is cleaned, and then the second drive motor 81 is reversely driven to return the rotated movable support 72 as shown in FIG. 11a. At the same time, by inserting seeds into the planting surface (20a) and clamping the front door (30), it is possible to continue growing sprouts.

Although embodiments of the present invention have been described above with reference to the attached drawings, those skilled in the art will understand that it can be implemented in other specific forms without changing the technical idea or essential features. will be.

Therefore, the embodiments described above should be understood in all respects as illustrative and not restrictive, and the scope of the present invention described in the detailed description is indicated by the claims described later, and the meaning and scope of the claims. The scope and all changes or modified forms derived from the equivalent concept should be construed as being included in the scope of the present invention.
