In particular, the first and second rotation axis directions 76 and 77 are formed to be orthogonal to each other so that the driving motor 81 of the blower 80 is rotated when the blower 80 described later rotates by the rotary drive unit 90. ) Can be easily supported.

Blower 80 is for generating wind, the drive motor 81 is installed on the motor fastening portion 71 of the second rotary frame 70, the drive motor is coupled to the lower end of the drive motor 81 And a blowing fan 82 that rotates by the driving force of the 81.

The rotation driving unit 90 is for changing the blowing direction of the blower 80, and includes a deceleration member and first and second extension members 92 and 93.

The reduction member is not shown to be installed inside the reduction box 91 provided at the upper end of the driving motor 81, but integrally with the driving shaft of the driving motor 81 in the reduction box 91. It includes a rotating rotary gear and a reduction gear engaged with the rotary gear.

The first extension member 92 is fixed to the reduction gear and extends upwardly from the reduction gear, and the second extension member 93 extends from the first extension member 92 toward the central axis 12 and has a central axis ( 12 is formed to the insertion hole is fastened, the first extension member 92 can be rotated about the central axis (12). The first extension member 92 may be provided with a separate bearing so that it can be easily rotated about the central axis (12).

The first extension member 92 and the second extension member 93 are connected to form an acute angle. Therefore, the end of the first extension member 92 connected to the second extension member 93 is spaced apart a predetermined distance in the radial direction from the central axis 12, but the deceleration member connected to the first extension member 92 Alternatively, since the driving motor 81 extends in parallel with the first extension member 92, the driving motor 81 intersects with the vertical axis direction parallel to the central axis 12.

In this way, since the first and second extension members 92 and 93 are connected at an acute angle, the driving motor 81 extends inclined with respect to the vertical axis extending in the vertical direction.

In addition, the second extension member 93 is configured to move a predetermined distance up and down along the longitudinal direction of the central axis 12, the engaging portion with the central axis 12.

As described above, since the first extension member 92 is fixed to the center of the reduction gear, the first extension member 92 is spaced apart from the drive shaft of the drive motor 81 by a predetermined distance. Since the first and second rotation frames 60 and 70 rotatably support the driving motor 81 about an extension line passing through the driving shaft of the driving motor 81, the driving motor 81 is rotated. The separation distance between the central axis 12 and the drive shaft of the driving motor 81 is constant, but the separation distance between the central axis 12 and the first extension member 92 is variable. However, since the length of the second extension member 93 is constant, the change in the separation distance between the central axis 12 and the first extension member 92 according to the rotation of the driving motor 81 is the first, second As the load is added to the reduction gears and the rotary gears, including the extension members 92 and 93, the possibility of breakage in these components becomes very high.

Therefore, the coupling portion of the second extension member 93 coupled to the central axis 12 is movable in the vertical direction along the longitudinal direction of the central axis 12, so that the center according to the position during the rotation of the drive motor 81 The change in the separation distance between the shaft 12 and the first extension member 91 can be compensated for.

Rotation of the blower 80 by the rotation driving unit 90 is made through the following process.

When the driving motor 81 is driven, the blowing fan 82 rotates by the driving force of the driving motor 81 to generate wind. In the upper portion of the drive motor 81, a rotary gear which rotates integrally with the drive shaft of the drive motor 81 rotates, and the reduction gear engaged with the rotary gear also receives this rotational force.

The reduction gear ratio of the reduction gear may be variously formed as necessary. For example, if the driving motor 81 rotates at 1500 rpm, when the amount of rotation of the blower 80 per minute is limited to 5 to 10 times, the reduction gear By reducing the rotation speed of the freezing drive motor 81 to 1/150 to 1/300, the rotation speed of the reduction gear is made to be the rotation speed of the blower 80.

Since the second connecting member connected to the first connecting member fixed to the reduction gear is rotatably coupled to the central shaft 12, the entire blower unit 80 is connected to the second central axis 12. As the members rotate, they rotate together.

Thus, the blower 80 is rotated in the inclined state by the rotary drive unit 90 to expand the blower region, and the entire blower can be blown through the minimum blower 100.

In addition, since the first and second rotation frames 60 and 70 are rotatably installed around the rotation axis directions intersecting with each other, the blower 80 may be easily supported when the blower unit 80 rotates.

When the blower according to the present invention is installed in a barn that needs a blower, the installation cost is reduced to 50% than the general blower, and the maintenance cost is minimized by reducing the moisture control unit (chaff, sawdust), and harmful gas The minimization of the occurrence greatly contributes to the growth and development of the livestock, so the industrial applicability is very high.
