Description

[Detailed description of the invention] (a) Industrial application field The present invention relates to a gas brooder for agricultural and livestock farming.

(b) Conventional technology A gas broider in which a plurality of gas burners are arranged inside a dome-shaped reflector is already well known.
There are also models on the market that are equipped with a thermostat to automatically set the desired temperature.

(c) Problems to be solved by the invention As mentioned above, in a brooder equipped with multiple gas burners (for example, 6 to 9 burners), heating and combustion control over a relatively wide area is required. Of course, it is possible to carry out efficient rearing by using a gas brooder, but the design of gas brooders, which are heaters for raising livestock, is usually based on the standard number of birds and animals (breeding space) per device. , the maximum calorific value is set taking into account the extremely cold temperatures, but gas burners are designed based on the maximum calorific value, so
There is a limit to the minimum amount of combustion that can naturally suppress the flame, and the smaller the flame, the more unstable the combustion state becomes, making accidents such as backfires and extinctions more likely to occur.

Raising chicks and piglets requires a small amount of heat insulation in spring and autumn, as well as in summer, but as it gets too hot in summer, the current practice is to release excess heat outdoors to maintain an appropriate temperature.

(d) Means for solving the problem Therefore, in the present invention, branch pipes connected to multiple gas burners from the gas terminal provided at the center of the reflective umbrella are each equipped with an opening/closing knob to operate them. The system is configured so that only the desired number of gas burners can be used for combustion, thereby expanding the temperature control range and making it possible to use fuel gas efficiently.Incidentally, there are many burners. The more the combustion amount is selected, the wider the selection range of the combustion amount becomes.

Hereinafter, the gist of the present invention will be explained based on the embodiments shown in the drawings.

(e) Embodiment FIG. 1 is a bottom view of the gas brooder of the present invention, and FIG. 2 is a longitudinal sectional view showing the main parts of the brooder.

In the drawings, reference numeral 1 denotes an outer reflector, and an auxiliary reflector 2 is provided inside it to improve the reflection efficiency of nine gas burners 3 arranged radially.

A gas terminal 4 is supplied with gas through a conduit 5, and gas is supplied to each gas burner 3 through branch pipes 6, 6, . Reference numeral 7 indicates an opening/closing knob placed on each of these branch pipes 6, 6... to open/close the branch pipe 6 to each gas burner 3, 3...
Each of them is designed to be able to perform combustion independently.

The above-mentioned conduit 5 is provided with a main tank 8 equipped with a safety device for shutting off, and a thermocouple 9 is made to face the lower part of one gas burner 3 via a conductive wire 10.

(f) Effect In the gas brooder of the present invention having the above configuration, normally all the gas burners 3, 3... are burnt at the same time by fully opening the opening/closing knobs 7 of the branch pipes 6, and the temperature is adjusted as follows. Normally, this is done using a thermostat (not shown), but the irradiation temperature due to combustion in all the gas burners 3, 3... has a limit of maximum temperature and minimum temperature, and especially when the temperature exceeds the minimum temperature, If it is desired to maintain the temperature at a low temperature, the temperature can be lowered by closing a required number of gas tanks 7 as necessary. At this time, it goes without saying that the combustion of the gas burner 3 facing the thermocouple 9 is carried out.

In this case, the temperature will be maintained low by the reduction in the number of gas burners 3.

The above shows an example of use at low temperatures, but in other usage situations, it is possible to freely close the desired number of gas burners 3 to adjust the temperature, and the temperature distribution within the irradiation range. It is also possible to change the

(g) Effects of the invention As described above, according to the invention, the opening/closing pot 7 is provided in each of the branch pipes 6, 6, . Depending on the gas burner 3, 3
...Since it is possible to freely burn only the desired burner inside, it is possible to delicately adjust the irradiation temperature and change the temperature distribution within the irradiation range. , even if the number of blades/heads is less than the standard number, it has the excellent feature of being able to select the appropriate number of burners and combustion amount without making the combustion of each burner too small, which contributes to practical use. It is quite remarkable.
