Description

[Detailed description of the device] "Industrial application field" The present invention is a germination in which seed rice before sowing is soaked in a water tank, subjected to treatments such as disinfection and cold / warm water so as to germinate into so-called pigeons. Regarding the device.

"Prior Art" In a conventional germination apparatus, a heater for heating was provided in an elongated pumping pipe standing upright in the germination tank. Further, as a water spray tank provided separately from the germination tank, there is one disclosed in Japanese Utility Model Publication No. 61-24071 published by the present applicant.
And, in these conventional germination devices, the amount of pumped water was constant.

[Problems to be solved by the invention] However, in such a conventional germination device, a heater, a temperature sensor, and the like must be arranged together with the pumping pump shaft in the elongated pumping pipe, which only requires manufacturing man-hours. However, there was a large difference between the water temperature in the pumping pipe and the water temperature in the germination tank, and if a temperature sensor was installed in the pumping pipe, the water temperature in the germination tank could not be detected accurately and was inaccurate. .
This has the same problem to some extent in the germination device according to the above publication.

In addition, conventionally, it is difficult to separate and divide the pumping pump, heater, temperature sensor, electric control unit, etc., and these are integrated even when the device is not used. For example, to store the electric part in a good condition for a long time It took a lot of work.

Furthermore, if the amount of pumped water in each step for germination is always constant, there are the following problems.

That is, in the first-stage disinfection process, if the circulating water flow is too fast, the rate of attachment of the disinfectant to the seed pad becomes poor, the disinfectant effect declines, and not only the incidence of so-called bakanae disease increases, but also the disinfectant Foaming caused by violently sprinkling water mixed with was violent, and overflow from the germination tank increased.

On the other hand, in the hot water dipping step, the amount of dissolved oxygen in the water decreases because the water temperature rises, and thus a large amount of circulating water is required. Therefore, there is a serious problem that the supplemental amount of oxygen is insufficient with a small amount of pumped water suitable for the disinfection process.

Furthermore, in the cold water immersion process, the amount of dissolved oxygen is relatively large, while on the other hand, the effect of the disinfection process is maintained to some extent.
Optimally, the water flow is intermediate between the disinfection step and the warm water immersion step.

Conventionally, the amount of pumped water has been designed to be commensurate with the warm water immersion process, fearing the adverse effect of reducing the amount of oxygen in water.

The present invention has been made by paying attention to such problems in the conventional technology. An appropriate temperature for germination can be accurately obtained, and the pumping amount corresponding to each process can be freely selected. Provide a germination device that can separate the sensor or the electric control part that is closely connected to these for convenient storage, and also separate other equipment easily so that the germination tank can be used independently The purpose is to do.

[Means for Solving the Problem] The gist of the present invention for achieving such an object is as follows: (1) A germination tank that is flooded to contain seed paddy, and detachably provided above this germination tank. A sprinkler tank having a large number of sprinklers, and a pumping pump unit for sucking water from the germination tank and pumping the water to the sprinkler tank, a heater for heating the sprinkler tank, and a temperature sensor. , A germination device comprising a water level sensor.

The germination device according to any one of paragraphs.

[Operation] Seed paddy selected by salt water selection is packed in appropriate-sized subdivision bags and loaded in the germination tank. Then, germination is carried out through the steps of disinfection, cold water immersion, and hot water immersion.

In the disinfection process, the pumping volume is relatively small and the pumping pump is set to rotate slowly.

Next, in the cold water immersion step, the pump is driven slightly faster than in the disinfection step, and the pumping amount is selected to be slightly higher. The heater is switched to the low temperature so that the water temperature is kept low, for example around 15 degrees Celsius.

In the next hot water immersion step, the water temperature is raised, so the heater is switched to the high temperature side. Then, in order to maintain the amount of dissolved oxygen in the water, the pumping pump rotates at high speed to circulate a large amount of water.

When not in use for a long period of time, remove the temperature controller and store it properly so that the electric parts can be sufficiently protected. On the other hand, if the water is dropped from the sprinkler tank, the pump is disconnected, the bolts are loosened to remove the sprinkler tank, and the support plate is also removed from the upper opening edge of the germination tank, the germination tank is used as another water tank for other purposes. You can Since the sprinkler tank is supported by only two bolts, it is extremely easy to install and remove.

The pumping pump unit 50 includes a pumping pump 51 and a submersible motor 52 for driving, which are integrated with each other. As shown in FIG. 2, the base is fitted into the circular cutout portion 23 a of the cage 23. It is submerged in water.

As shown in FIG. 1, the sprinkler tank 30 is composed of a horizontally long box-shaped main body 31 that is placed above the water surface of the germination tank 20 and a cover 32 that covers the upper surface of the main body 31. A plurality of sprinkler ports 33 as shown in FIG. 1 are provided. Even if these sprinkling ports 33 are rectangular so that the outflow water spreads widely as shown in the figure, or have another shape, at least the lower edge 33a of the opening is made horizontal.

And on both short side surfaces not provided with the sprinkling port 33,
As shown in FIG. 5, a fixing plate 34 for mounting is fixedly installed. Each of these fixing plates 34 has a support bolt 35.
The screw (not shown) for is screwed.

The sprinkler tank 30 and the pumping pump unit 50 are hoses.
They are connected by 53, and the inside of the main body 31 is connected to the perforated pipe 39. Further, a middle partition plate 31a is provided in the tank.

On the other hand, as shown in FIG. 5, on the upper edge of the body portion 21 of the germination tank 20, a pair of left and right support plates 36 having biting portions 36a that can be tightly fitted to the projecting portion 21a of the germination tank 20 are provided. It is arranged.

The heater 43 and the like are immersed in water in the water spray tank 30.

Next, the operation will be described.

The seed paddy selected by the salt water selection is packed in an appropriate-sized subdivision bag and loaded in the germination tank 20. Germination tank 20
When the seed paddy is loaded on, the sprinkler tank 30 is removed.
After the seed paddy is inserted, attach the sprinkler tank 30, start the pumping pump unit 50 while sprinkling the water, and the water is added to the germination tank 20.
And both sprinkler tanks 30 are full.

Then, germination is carried out through the steps of disinfection, cold water immersion, and hot water immersion.

In the disinfection process, the pumping amount is relatively small, and the pumping pump unit 50 is set to rotate slowly.

Next, in the cold water immersion step, the pumping pump unit 50 is driven so as to be driven a little faster than in the disinfecting step, and the pumping amount is selected to be slightly larger. The heater 43 switches to a low temperature so that the water temperature is low, for example, maintained at about 15 degrees Celsius.

In the next warm water immersion step, the water temperature is raised, so that the heater 43 is switched to the high temperature side. Then, in order to maintain the amount of dissolved oxygen in the water, the pumping pump unit 50 rotates at high speed to circulate a large amount of water.

Since the inner volume of the sprinkling tank 30 is relatively large, and therefore has a large heat capacity, there is almost no difference between the temperature inside the tank and the water temperature inside the germination tank 20, and the temperature sensor 44 is convenient for removal. Further, even if the temperature is detected as the water temperature in the sprinkling tank 30, it is substantially the same as the detection of the water temperature in the germination tank 20. In germination processing,
This is extremely useful in setting the temperature because the treated water temperature is the most important factor.

When not in use for a long period of time, remove the temperature controller 40 and store it properly so that the electric and electronic parts can be sufficiently protected. On the other hand, water is dropped from the sprinkler tank 30, the pumping pump unit 50 is separated, the bolt 35 is loosened, and the sprinkler tank 30 is removed.
Also, if the germination tank 20 is removed from the projecting portion 21a at the upper opening edge of the germination tank 20, the germination tank 20 can be used for other purposes as a simple water tank. Since the sprinkler tank 30 is supported by only two bolts 35, it can be attached and detached very easily.

The perforated pipe 39 in the main body 31 of the sprinkling tank 30 is provided in order to ensure that the water supplied by the pumping pump 51 is evenly distributed in the tank. Further, the reason why the sprinkling port 33 is rectangular or at least the lower edge of the opening is formed horizontally is to spread the sprinkling as much as possible.

When germination is complete, disconnect the top of hose 53,
Drain while operating the pump 51. Although the water in the sprinkler tank 30 naturally flows down and is drained by the pumping pump 51, both the germination tank 20 and the sprinkler tank 30 may be provided with a drain port at the bottom.

[Advantage of device] According to the germination device of the present invention, a heater for heating, a temperature sensor, and a water level sensor are integrated into a detachable temperature controller, and the temperature controller has a relatively large capacity. Since it is mounted on a sprinkler tank that is large and can be easily removed, it can be easily removed and protected and stored when not in use.

Also, since the temperature of the water temperature can be set and the speed of the pump pump motor can be changed, it is possible to select the optimum temperature condition and pumping condition corresponding to each step of the germination treatment.
Good quality sprouted rice can be easily obtained.
