Description

Automatic disinfection apparatus for seeds, using hot water}

The present invention relates to a device for disinfecting various seeds such as rice seed, red pepper seed, melon seed, pumpkin seed, watermelon seed, and more particularly, for hot water for a time required for disinfection (for example, 10 minutes) for all seeds to be added. It relates to a seed automatic hot water sterilizer to be exposed to good quality seeds.

Generally, in order to sow rice seeds and other seeds, disinfection should be done before sowing. In the past, disinfectants were used when disinfecting. However, in case of environmentally friendly farming, disinfectant should not be used, so that the seeds are soaked in water over 60 ℃ and the hot water is sterilized by soaking in hot water for an appropriate time.

Accordingly, a method has been developed for disinfecting seeds by placing them in hot water, which is about 10 to 15 minutes after placing the seeds in a mesh bag and placing them in a large container filled with water at a temperature of 60 ° C. After sterilization, the extraction is done. This disinfection method uses the principle that germs are disinfected by hot water while seeds are in hot water.

However, this disinfection method requires the seeds to come in contact with water in the container, and the seeds inside the sack and the outside seeds come into contact with water so that the disinfection is not uniform.

In other words, when the water temperature is set at the sterilization temperature (for example, 60 ℃ ~ 65 ℃), high quality hot water disinfection is performed by contacting water at the disinfection temperature for the seeds outside, but lower than the disinfection temperature for the seeds inside. Good hot water disinfection is not achieved due to contact with water of temperature.

On the contrary, if the temperature of the water is raised so that the seeds inside contact with the disinfection temperature, high quality hot water disinfection is performed on the seeds inside, but the seeds on the outside are ripened by contact with too high water. Will not be able to.

As described above, the conventional method of disinfecting the seed hot water has a problem in that the hot water disinfection cannot be brought into contact with water of a uniform quality because the seeds do not come into contact with water at a disinfection temperature.

In order to solve such a problem, the applicant has developed a "seed hot water sterilizer" as shown in FIG. 1 and has been registered in Korean Patent No. 10-854494. The conventional "seed hot water sterilizer" is a disinfection vessel 10 for storing water for disinfecting seeds, a hopper 90 for supplying seeds to the disinfection vessel 10, and heats the water inside the disinfection vessel 10. The heating heater 11, the temperature sensor 12 for detecting the water temperature of the disinfection vessel 10, the control box 13 for controlling the heating heater 11 in accordance with the detection signal from the temperature sensor 12 , As the seed of the hopper (90) is lowered to the lower portion of the disinfection container (10), the water is allowed to go out at the top, but the seeds are cylindrical hot water tank (20) formed at regular intervals through the gap of the size, the hot water Water supply pipe 30 for supplying water from the lower portion of the hot water tank 20 to the upper portion so as to disperse seeds coming down by its own weight into the container 20, the water suction pipe 32 to the water supply pipe 30 Circulating pump (31) for supplying water to the lower end of the hot water tank (20) A large diameter housing tube 40 temporarily storing the seeds, the transfer pipe 50 for extending the seeds from the lower portion of the disinfection container 10 to the top to transfer the seeds to the outside, and the air pump 61 It is composed of an air blowing pipe 60 for ejecting the compressed air to the inlet of the transfer pipe (50) by blowing compressed air from

The conventional seed hot water sterilizer is a seed is introduced into the hot water tank 20 in the hopper 90 and slowly descends from the hot water tank 20 while staying in the hot water tank (20) for the time required for disinfection and then transported by compressed air ( Through 50). The time required for disinfection is about 10 minutes.

However, since the seed injected from the hopper 90 quickly descends in the hot water tank 20, the seed is discharged to the outside through the storage tube 40 and the transfer tube 50 without being properly disinfected. there was.

However, after 10 minutes have passed since the seeds are filled in the hot water tank 20, the compressed air is ejected from the air ejection pipe 60, and when the seeds are discharged from the seeds at the bottom in order, the seeds at the top are heated longer than necessary. The phenomenon of staying on.

Thus, the conventional seed warm water sterilizer has a problem that it is difficult to keep the seeds stay in the warm water for the time required for disinfection.

The present invention, in order to solve the problems of the prior art as described above, all seeds to be disinfected in the hot water tank after staying for a time required for disinfection, by discharging the seed automatic hot water quality is good and uniform for all seeds The aim is to provide a sterilizer.

The disinfection container 10 is a container for storing water for disinfecting seeds, and the water is heated therein to sterilize various seeds such as rice seeds by the hot water.

The inside of the disinfection vessel 10 is a heating heater 11 for heating the water is installed at the bottom, and the temperature sensor 12 for detecting the temperature of the water in the disinfection vessel 10 is a disinfection vessel ( It is installed on one side of the inside.

In addition, the control box 13 for detecting the temperature of the water according to the detection signal from the temperature sensor 12 and controlling the heating heater 11 so that the temperature of the water becomes a predetermined temperature is appropriately located outside the sterilization container 10. Is installed.

The hot water tank 20 is formed in a cylindrical shape, the seed supplied from the outside is lowered to the lower portion of the disinfection container 10, and the water is allowed to go out, but the seeds through the holes 21 of the size does not escape at regular intervals Formed.

The water supply pipe 30 is to disperse the seeds coming down by the weight into the hot water tank 20, one end of the water supply pipe 30 is installed on the outside of the disinfection vessel 10 and the water suction pipe (one side) 32 is connected to the water outlet of the circulation pump 31 is connected. The other end of the water supply pipe 30 passes through the receiving tube 40 which will be described later connected to the bottom of the hot water tank 20 and then extends to the center of the bottom of the hot water tank 20, and the upper end of the water supply pipe 30 has a plurality of discharges. It is connected to the annular water jet pipe 142 in which a ball is formed. The discharge hole of the annular water jet pipe 142 is formed to blow water in all directions in the upward inclined direction.

The housing tube 40 is connected to the lower end of the hot water tank 20 to temporarily receive seeds, and is bent at a right angle and the upper end in the vertical direction is connected to the lower end of the hot water tank 20 and has a horizontal direction on the other side. The inclination part is formed so that the diameter may narrow gradually, and the lower end part of the conveyance pipe 50 mentioned later is connected to the edge part of this inclination part.

The transfer pipe 50 extends from the lower portion of the disinfection container 10 to the upper end and has a function of transferring seeds contained in the accommodation tube 40 to the outside, in an upward direction of the transfer tube 50. It is fixed to the disinfection container 10 in an inclined state.

The air blowing pipe 60 is to blow the compressed air into the inlet of the transfer pipe 50 from the air pump 61 installed on the outside of the disinfection container 10, the transfer pipe (60) through the air blow pipe (60) 50) the compressed air is ejected into the seed through the inlet of the receiving tube 40 to be discharged through the outlet of the transfer pipe (50).

The air blower pipe 60 is horizontally directed toward the inside of the transfer pipe 50 in a state where one side thereof is connected to an air outlet of the air pump 61 and the other side passes through a through hole formed in the accommodation tube 40. It is installed in the direction.

At the top of one side of the disinfection container 10 receives the seed seed falling down through the discharge port of the transfer pipe 50 so that the water on the seed is dropped into the disinfection container (10) and the seed is some amount of the seed storage The seed strainer 70 is inclined downward so as to fall into the container 80.

As shown in Figure 4, the seed support 110 is formed in a funnel shape, on both sides of the inner surface of the rim portion bent vertically to the upper end of the seed support 110, the support of one side (112a) is formed ( 112) and the lower ends of the support 113 on the other side are fastened with fastening bolts, respectively. Upper ends of the supports 112 and 113 on both sides are connected to both ends of the connection table 114.

Supports 112 and 113 are installed to penetrate the hollow portion of the guide 120 on both sides installed with fastening bolts on both sides of the inner surface of the hot water tank 20 to move up and down within the hot water tank 20.

The rack 112a of the support 112 is engaged with the pinion 131 of the reduction motor 130 to be described later, and the support 112 and 113 on both sides are moved downward in accordance with the rotation of the pinion 131. Accordingly, the seed support 110 coupled to the lower ends of the support members 112 and 113 on both sides may move downward from the inside of the hot water tank 20.

The rack 112a is formed only at a lower portion of the one side support 112. The reason for this is that the time taken for the seed support 110 to descend to the bottom of the hot water tank 20 is the time required for proper disinfection of the seeds in warm water (about 10 minutes). In order to engage the pinion 131 and afterwards the engagement is released so that the seed support 110 is quickly dropped to the bottom of the hot water tank (20).

The reduction motor 130 has a pinion 131 is installed on the central axis and the pinion 131 is configured to engage with the rack (112a) and is installed on the upper side of the outer surface of the hot water tank (20).

The reduction motor 130 is provided with a reduction gear, which makes the rotation speed of the pinion 131 very slow.

The reason for slowing the rotation speed of the pinion 131 is that the time taken for the seed support 110, which is moved downward by the pinion 131, to descend from the hot water surface to the bottom of the hot water tank 20 is caused by the seeds to be properly heated. This is to allow the pinion 131 to rotate slowly to take about 10 minutes, which can be disinfected.

The rack 112a is engaged with the rack 112a only while the pinion 131 is rotated two and a half turns, so that the pinion 131 rotates one turn and thereafter, the rack 112a is separated from the engaged state. 110 has a length that can quickly fall to the bottom of the hot water tank (20).

The guide pipe 140 in the shape of the hollow park is installed in the vertical direction at the inner center of the hot water tank 20, and a seed outlet 143 is formed at the bottom thereof, and the entire height thereof is formed to extend above the water surface. The opening is in communication with the outside air. And the guide hole 111 is inserted in the center of the seed pedestal 110 is configured to guide the seed pedestal 110 to move up and down.

The supporting net 141 is fixed to the upper end of the guide tube 140 so that the seed supplied from the outside does not enter the hollow part. Seed outlet 143 is formed between the support 144 in the lower portion of the guide tube 140, the seed outlet 143 is a passage function for the seeds of the seed support 110 to fall to the lower storage tube 40 And at the same time, it also functions as a passage through which the air ejected from the annular water jet pipe 142 is introduced.

The annular water ejection pipe 142 is formed with a discharge port at regular intervals, is fixed to the inner surface of the seed outlet 143 of the guide tube 140, the water supply pipe 30 is connected to the water through the discharge port It is configured to eject in all directions in the inclined direction upward.

In the drawings, reference numeral 14 denotes a wheel installed at the bottom of the disinfection container 10.

Seed automatic hot water sterilizer of the present invention configured as described above acts as follows.

As shown in FIG. 2, the temperature of the water (eg, 60 ° C. to 65 ° C.) is set in advance in the control box 13, and the heating heater 11 is operated to heat the water in the disinfection container 10. . The control box 13 controls the heating heater 11 while sensing the temperature of the water by the signal from the temperature sensor 12 to heat the temperature of the water to 60 ℃ ~ 65 ℃.

When the temperature of the water is heated to the desired temperature to operate the circulation pump 31 and the air pump 61 and put the seeds to be disinfected to the top of the seed support 110 inside the hot water tank (20). This state is the state of FIG. In this state, only the seeds at the bottom are soaked in hot water. The hot water is introduced into the seed holder 140 through a gap between the seed holder 110 and the guide tube 140 and a gap between the hot water reservoir 20 and the seed holder 140.

The circulation pump 31 also operates to circulate the hot water inside the hot water tank 20 while ejecting the water into the hot water tank 20 through the annular water jet pipe 142 to uniformize the hot water temperature. And since the hot water in the upper portion of the hot water tank 20 enters and exits through a plurality of through-holes 21 formed in the middle portion of the hot water tank 20, the water surface of the inside of the hot water tank 20 is the same as the water surface of the outside.

In this state, when the deceleration motor 130 is operated, the rack 120a engaged with the pinion 131 by the operation of the pinion 131 slowly descends to the lower side of the hot water tank 20 and accordingly the seed support 110 Also descends slowly. As the seed support 110 descends, the seeds descend from the lower part to the upper part and are immersed in hot water. And if there is a space in the hot water tank 20 due to the falling of the seeds continue to put the seeds to sterilize.

The output speed of the deceleration motor 130 rotates at a rate of 1/4 rotation per minute, and when it is operated for about 10 minutes, the pinion 131 rotates two and a half halves, so that the position of the seed rest 110 is one dashed line in FIG. You will be at the marked location. In this case, the pinion 131 and the rack 120a are released from each other so that the seed rest 110 falls rapidly to the bottom of the hot water tank 20 at the position indicated by the solid line in FIG. 3 by its own weight. And the operation of the reduction motor 130 is stopped.

When the seed support 110 reaches the bottom of the hot water tank 20, the seeds are dispersed and dispersed by the water jetted into the hot water tank 20 through the annular water jet pipe 142, and the seeds are evenly disinfected evenly by the hot water. This is done.

Subsequently, it enters the storage tube 40 through the inlet of the storage tube 40 which is temporarily stored. As the air is ejected from the air pump 61 through the air blower pipe 60, the seeds are raised along the transfer pipe 50 in the housing pipe 40. When the seed rises to the top of the transfer pipe 50 is discharged through the outlet of the top.

The seeds and water dropped into the seed strainer 70 at the lower side through the discharge port so that the water falls back into the disinfection container 10 so that the seeds fall into the seed container 80 at the lower side of the seed strainer 70.

Since the extra air from the air supplied through the air blower pipe 60 is discharged into the atmosphere through the interior of the guide tube 140, the extra air in the housing tube 40 does not interfere with the movement of the seeds.

As described above, the time when the seeds of the lower part of the seeds contained in the seed support 110 descends from the starting position to the bottom of the hot water tank 20, that is, the time when the seeds are immersed in the hot water, is required to disinfect the seeds. It becomes minute. And sequentially the seeds of the upper through the seed outlet 143, so that not only the initial seed, but also all subsequent seeds are soaked in warm water for about 10 minutes is uniformly sterilized. The time the seeds are soaked in warm water can be adjusted by controlling the rotational speed of the reduction motor 130 as needed.

Since all the deceleration motors 130 are provided with an overrunning clutch for transmitting rotational force in the direction of lowering the rack 120a and turning in the opposite direction, the end of the disinfection work is completed, and the support 114 is pulled out by pulling the connecting rod 114. 113 and the seed support 110 may return to the state of FIG. 2 to continue working next time.

Although the invention has been described in detail only with respect to the described embodiments, it will be apparent to those skilled in the art that various changes or modifications can be made within the spirit and scope of the invention, and such changes or modifications are therefore to the appended claims. It will have to belong to the scope of.
