Description

[Detailed description of the invention] This invention relates to a hot water soil disinfection device that exterminates pests and pathogens that infiltrate the cultivation soil of greenhouses and greenhouses, and promotes the healthy growth of cultivated plants such as vegetables and fruits. In particular, by using hot water as a heat medium and burying it in the greenhouse soil in a closed circulation path,
This invention relates to an excellent cultivation soil disinfection device for a greenhouse that eliminates wasteful diffusion of heat, has extremely high thermal efficiency, and also doubles as indoor heating, allowing effective soil disinfection.

As is well known, conventional methods of exterminating pests and pathogens living in the cultivation soil of greenhouses and greenhouses include using pesticides and steam, but these methods have a negative impact on vegetables and fruits. Besides, it is extremely harmful when handling pesticides and eating vegetables and fruits. Also, the steam extermination method requires a steam boiler, which increases the size of the equipment.

Equipment costs will be high, and therefore production costs will be high.

■A license is required to operate a steam boiler, so
- It is difficult to form a film.

■Since it is a partial disinfection, the extermination effect is small.

■Low heat retention, resulting in high fuel consumption.

This method has various practical disadvantages such as the above, and even if the method of exterminating fallen plants has a certain extermination effect, it is of low practicality in the above-mentioned respects.Therefore, this idea was developed to disinfect the cultivated soil in a greenhouse. In the device,
A water supply body for disinfection, which forms a closed pipe, is buried in the soil of the greenhouse, and hot water heated by a hot water boiler is supplied from the starting end of the flow passage via an appropriate pump, and the water supply body is flowed. As time passes, heat is emitted into the soil to warm it, thereby exterminating pests and pathogens in the soil, and the remaining hot water after the heat is released is returned to the hot water boiler. Therefore, we would like to provide an extremely economical and highly practical cultivation soil disinfection device for a greenhouse, which conducts the amount of heat necessary only for heating the soil. It is something to do.

An embodiment in which this invention is applied to a greenhouse will be described below in detail based on the drawings.

In the example diagram, reference numeral 1 denotes a heating water supply pipe that circulates hot water sent from a hot water boiler B installed at the indoor periphery of a greenhouse 2 via a water supply pump P, and here it is a - row two-stage type. Each longitudinal side of 2 is constructed by connecting a large number of hot water pipes 1a with cooling fins, and the starting end is connected to the outlet of the hot water pump P, and the terminal end is connected to the suction port of the hot water pump P. Hot water sent from the hot water pump P is circulated through two channels as shown by the arrows in FIG.

Reference numeral 3 denotes a disinfection pipe having a starting end connected to a starting end valve 4 using a gate valve or the like provided on the hot water pipe 1, and a terminal end connected to a terminal end valve 4' using a gate valve or the like. The hot water supply body forms a closed pipeline parallel to the hot water supply pipe 1, and has a meandering shape as a whole, and is located 20 to 25 minutes below the cultivation soil.
It is buried in CrrL.

The water supply body 3 for disinfection here uses a gas pipe, and in order to facilitate installation and storage, it is constituted as a divided body, with each divided body being connected to each other by a nipple 5.

Note that 6 in Figure 5 is the foundation concrete block 2a of greenhouse 2.
This is a support bracket for the hot water pipe 1 fixed to the.

The hot water soil disinfection device of this embodiment normally heats the room using the water supply pipe 1, but if pests or pathogens inhabit the cultivation soil due to repeated cultivation, the disinfection water supply body 3 is connected to the water supply pipe. 1, and the surface of the cultivation soil is covered with a vinyl chloride sheet 7 using studs 8, and hot water from hot water boiler B is connected to each connection valve 4, 4'. The hot water is opened and taken in from the hot water pipe 1, and pests and pathogens are silently killed and exterminated by the radiated heat of the hot water.

The hot water that has flowed through the pipe while dissipating heat is returned to the return side of the hot water pipe 1 through the valve 4' on the terminal end side.

In other words, the hot water flowing through the disinfection water supply body 3 releases only the amount of heat necessary for soil disinfection and is returned to the boiler, so there is no wasteful consumption of heat, making it extremely economical. becomes higher.

As explained in detail above, this invention uses hot water as a means to exterminate pests and pathogens living in the cultivation soil.
It is not harmful at all like the pesticide extermination method, and it is very easy to handle and simplify the equipment instead of a steam boiler, which requires a license and requires a license. In addition, since a hot water boiler, which is low in production cost and does not require a license, is used as the heat source, there are no practical disadvantages like conventional extermination methods.

In addition to the above-mentioned points, this idea has a specific structure in which a circulating hot water pipe 1 for hot water sent from a hot water boiler B via a hot water pump P is installed indoors, and this circulating hot water pipe 1
At each of the inlet and outlet connection valves 4 and 4' provided in The circulating hot water pipe 1 is normally used for indoor heating, and during disinfection, the disinfecting hot water body 3 is attached to supply hot water from the circulating water pipe 1. Coupled with the fact that it is possible to silently kill and exterminate the insects, it is possible to use the hot water pipes of existing indoor hot water heating equipment in greenhouses etc. that have existing indoor hot water heating equipment, making it extremely economical. expensive.

The disinfecting water supply body 3 is very easy to install, and the entire body constitutes a heat dissipation part and has excellent thermal conductivity, so it has an extremely high extermination effect and a large heat retention capacity. Therefore, it has the effect of reducing fuel consumption.

Furthermore, in this invention, the water supply body 3 for disinfection is buried in the cultivation soil, so there is extremely little danger from heat.

Furthermore, as in the example, if the surface of the cultivated soil is covered with a vinyl chloride sheet γ during disinfection, the heat conductivity and heat retention ability can be further increased, and the escape of pests and pathogens can be prevented. This has the advantage of completely exterminating the pests and pathogens that live in the cultivation soil of cultivation rooms such as greenhouses and greenhouses.

In addition, this invention allows hot water sent from a hot water boiler via a hot water pump to be directly connected to the hot water pump without the need for a hot water pipe, especially when disinfecting cultivated soil outdoors such as fields. , and the same exterminating effect can be expected even if the water is allowed to flow into a disinfecting hot water body buried in the cultivation soil as described above.

In addition, the structures of the hot water pipe 1 and the disinfecting hot water body 3 in this invention are not limited to those of the embodiments, and may be modified in various designs as long as they do not deviate from the technical idea stated in the claims for utility model registration. Of course there are changes.
