That is, the fixing bolt 154 passes through the first through-hole 148 through the lower portion of the support piece 144, and at this time, the head of the fixing bolt 154 is draped over the lower portion of the support piece 144, and the second By fastening the female thread formed in the second through hole 152 of the cover piece 150 to the male screw portion of the fixing bolt 154 passing through the first through hole 148 , the cover piece 150 is connected to the support piece 144 and It is paired to hold the metal protective tube 112 .

Here, the length of the width of the receiving groove 146 formed in the support piece 144 of the hanger bracket 142 disposed on the non-heating part side of the heat transfer unit 110 is equal to the length of the diameter of the metal protection tube 112 or The length of the width of the receiving groove 146 formed in the support piece 144 of the hanger bracket 142 disposed on the effective heating part side of the heat transfer unit 110 and having a short length in consideration of the thermal expansion of the metal protection tube 112 . It is formed larger than the length of the diameter of the metal protective tube (112).

That is, the metal protective tube 112 on the non-heating part side of the heat transfer unit 110 is strongly gripped without flowing by the support piece 144 and the cover piece 150 , and the effective heat generating part side of the heat transfer unit 110 . The metal protection tube 112 is movably gripped between the support piece 144 and the cover piece 150 .

Meanwhile, the fixing bolt 154 enables the hanger bracket 142 to hold the metal protection tube 112 as described above, and at the same time fixes the heat transfer unit 110 to the heat reflection plate 130 .

To this end, the fixing bolt 154 vertically penetrates the third through hole 136 formed in the first reflecting member 132 . At this time, a normal eye nut 156 is attached to the male screw portion of the fixing bolt 154 extending through the third through hole 136 to the rear surface of the first reflective member 132 , that is, to the outer surface side of the first reflective member 132 . ; eyenut) is fastened.

And on the surface of the first reflective member 132 , that is, on the inner side of the first reflective member 132 , a lock nut 160 is fastened to the fixing bolt 154 , in this way the first reflective member 132 . ) between the eye nut 156 and the lock nut 160 fastened to the male threaded part of one fixing bolt 154, the fixing bolt 154 is secured so that the fixing bolt 154 does not flow up and down. It is fixed to the first reflective member 132 .

That is, under a state in which the eye nut 156 is fastened to the male threaded portion of the fixing bolt 154 extending toward the outer surface of the first reflective member 132 , the lock nut 160 is formed on the inner surface of the first reflective member 132 . When moving to the side, the fixing bolt 154 is fixed to the first reflective member 132 so as not to move vertically.

On the other hand, the eye nut 156 is formed with a ring 158 that can connect a pin or a rope R as anyone can see, and the ring 158 of the eye nut 156 thus formed is in the present invention. It allows the pig heating device 100 to be installed by hanging from the ceiling of the pig house, etc. (see FIG. 4 ).

1 and 2, one clamp 140 for holding the effective heating part side of the heat transfer unit 110 is shown, but anyone can see that the number of clamps 140 can be increased according to the length of the effective heating part There will be.

On the other hand, the heating device 100 for pigs according to the present invention is a pest control unit 170 that uses the heating heat generated from the heat transfer unit 110 to exterminate pests, preferably flies, mosquitoes, etc. in the pig house (P). ) may be further included.

The pest control unit 170 is one or more provided on the heat reflection plate 130, preferably the first reflection member 132, as shown in FIGS. 5 and 6, and the pest control unit 170 is the holder 172 ), and a fumigation container 174 and an attracting trap 176.

The holder 172 is provided in a horizontal ring shape having a predetermined thickness, and the lower portion is fixed to the outer surface of the first reflective member 132 .

That is, the holder 172 is fixed to the first reflecting member 132 so as to protrude outside the outer surface of the first reflecting member 132 when the heat reflecting plate 130 is viewed from the side or the front.

A fumigation container 174 is accommodated in the holder 172 fixed to the first reflecting member 132 in this way, and the holder 172 supports the received fumigation container 174 .

The fumigation container 174 is provided in a common container shape that can contain the liquid pest insecticide (I) and the like therein, preferably closed on the side and the bottom, and the top is open and the inside is empty.

And the fumigation container 174 is accommodated in the inside of the holder 172 under a state in which the liquid pest insecticide (I) is contained therein, at this time the closed lower portion of the fumigation container 174 accommodated in the holder 172 is the first reflection It is in contact with the outer surface of the member 132 .

That is, the heating heat generated by the heat transfer unit 110 is The reflective member 132 is heated, and the heat of the heated first reflective member 132 is conducted to the lower part of the holder 172 and the fumigation container 174 to heat the pest insecticide (I) contained in the fumigation container 174. and the heated pest insecticide (I) releases steam while evaporating to exterminate pests.

And the heat of the first reflective member 132 is conducted to the holder 172 like the fumigation container 174, and thus the holder 174 to which the heat of the first reflective member 132 is conducted is the fumigation container 174. Prevents the thermal energy from moving to the holder 172 side, so that the pest insecticide (I) contained in the fumigation container 174 can be quickly heated.

On the other hand, the inlet trap 176 is to be able to attract pests, particularly flies, etc. to the fumigation container 174 side, the inlet trap 176 is a tray 178 having a concave cross section covering the open top of the fumigation container 174. ) is included.

A bait capable of attracting pests, particularly flies, etc. is contained inside the tray 178, and the tray 178 is formed with a plurality of steam discharge holes 180 so that the steam of the fumigation container 174 can be discharged. do.

Here, the bait may be a food to which the vapor of the pesticide (I) is adsorbed, and to absorb the adsorbed vapor, for example, food such as bread.

And the inlet trap 176 further includes a flange 182 for supporting the tray 178 on the upper portion of the fumigation vessel 174 so that the tray 178 can cover the upper portion of the fumigation vessel 174.

The flange 182 is integrally formed along the edge of the tray 178 as shown, and the lower portion of the flange 182 thus formed is spanned over the upper portion of the fumigation vessel 174 . Accordingly, the upper portion of the fumigation container 174 is covered by the tray 178 .

Since the pest control unit 170 formed in this way can evaporate the pest insecticide (I) using the heating heat of the heat transfer unit 110, the vapor generated during evaporation can be diffused throughout the pig house (P), thereby By adsorbing the vapor of the pest insecticide to the pests, it is possible to provide an effect capable of exterminating the pests.

On the other hand, in FIGS. 1 to 6, the heat reflection plate 130 including the first reflection member 132 and the pair of second reflection members 134 integrally bent on both sides of the long side of the first reflection member 132.
