Abstract

PURPOSE:To aim at making a suspending type blower lightweight, by fitting a support beam spanning an orifice and projecting from the outer periphery to secure a propeller fan and a motor, and by rotatably providing an attachment on the support beam. CONSTITUTION:A motor 109 is attached to a motor support bed 204 which is secured to a pipe 202 spanning a bell-mouth 201 and serving as an orifice during air blow. Two support pipes 214 are provided to the pipe 202 through the intermediary of an attachment 216, and attaching holes 215 in the support pipes 214 are rotatably coupled with holes 220 in the pipe 202. Accordingly, it is possible to facilitate the adjustment of the attaching angle of the blower with no attaching frame or the like being required, thereby it is possible to aim at making the blower body lightweight.

Description

DETAILED DESCRIPTION OF THE INVENTION Field of the Invention The present invention relates to a hanging type blower used for ventilation in livestock houses such as chicken houses and cow houses.

Conventional technology Generally, when blowing air in one direction in a livestock barn, a blower is hung from the ceiling in order to effectively utilize the floor space.
Normally, hanging fittings are separately manufactured and used for general wall-mounted ventilation fans, and there was a demand for lightweight and easy installation.

Conventionally, this type of hanging type blower has a structure as shown in FIGS. 3 and 4. That is, the main body panel 102 is made of a rectangular steel plate, and has L-shaped upright parts 1 bent on its four sides.
02a and a bellmouth-shaped opening in the center. Two pipes 101 formed in a bridge shape on a diagonal line are fixed at a predetermined interval. A bearing stand 103 is fixed to the center of this pipe 101,
The rotating shaft 106 is held perpendicular to the opening of the bell mouth, and a motor 109 is attached to one end of the rotating shaft. I! l1l
1109a is fixed so as to be parallel to the rotating shaft 106. The rotating shaft 109a has a motor pulley 110 on the driving side, and the motor pulley 11 on the rotating shaft 106.
A fan pulley 107 which becomes the driven side is on the side parallel to 0.
is fixed, and a belt 111 is passed between them to drive the blades 1os attached to the main body (flank side) of the rotating shaft 106.The rising portions 102aiC of the opposing outer edges of the main body panel 102 have a cross-sectional shape. The length of the mounting bracket 113, which is longer than one side of the main body panel C12, is attached to each bolt 11.
4a and a nut 114b. A mounting hole 112 is provided at the tip of the mounting bracket 113, and the mounting bracket 113 can be hung by fixing it to a ceiling surface with bolts or the like.

Problems to be Solved by the Invention In such a conventional configuration, except for the mounting bracket 113, the rest is a wall-mounted fan, and the main body wall (the flannel 102 is unnecessary), and the mounting bracket 113 is separately installed. Because they have to be manufactured and installed, there are economic problems in that they require extra weight and installation time, which increases manufacturing costs, and there are also functional problems in that the entire structure is fixed and the wind direction cannot be easily adjusted.

It is an object of the present invention to solve these problems and provide a hanging type blower that is lightweight, economical, and easy to use.

Means for Solving the Problem In order to solve this problem, the present invention fixes a support beam made of two pipes or the like at a constant interval parallel to the surface of the bellmouth-shaped orifice, and A propeller fan and a motor for driving the propeller fan are provided at a position facing the center of the orifice of the support beam, one end of the support beam extends from the outer periphery of the orifice, and the outer edge of the shaft support of the propeller fan includes a propeller fan and a motor for driving the propeller fan. A hanging type having a main body configured with a slot, one end fixed at an arbitrary position in the slot, and a mounting bracket near the other end rotatably supporting the extended end of the support beam. It has the configuration of a blower.

Operation With the above configuration, the support beam forms the frame of the main body and also serves as the mounting part of the main body, and the mounting bracket that is fixed to the installation part is locked at two points, the shaft support and the slot, so that the main body can be held at a constant position. The fixed position and tilt can be adjusted within a range.

EXAMPLE An example of the present invention will be described below with reference to FIGS. 1 and 2. In the figure, 201 is a bell mouth that serves as an orifice during air blowing, and a pipe 202 is fixed across the center of the end surface on the blowing side by a fixing method such as welding. This pipe 202 is bent into a U shape in parallel at regular intervals, and both ends thereof protrude from the outer periphery of the bell mouth 201, and a hole 220 is provided near the end of this protrusion 202a. A bearing 20 is installed in the center of the pipe 202.
6 is fixed such that the axis of the bearing 205 coincides with the center of the bell mouth 201. A rotary shaft 206 is inserted through the bearing 205, and a fangoo 1J207 is fixed to the pipe 202 side, and a propeller-shaped blade 208 is fixed to the suction side of the bell mouth 201. A motor support stand 204 is fixed so as to straddle the two protrusions 202a of the pipe 202, and a motor 209 is attached thereto. Rotating shaft 20 of this motor 209
6 is fixed parallel to the center of the bell mouth 201 toward the pipe 202 side, and is attached so that the motor pulley 211 is flush with the fan pulley 207. A driving belt 212 is stretched between the motor pulley 211 and the pulley 207. The shaft support stand 2
An angle adjustment table 213 having an arcuate hole 221 with the hole 220 of the pipe 202 as a fulcrum is located on the opposite root side of the pipe 20.
2 and is fixed perpendicularly to the shaft support 203, thereby forming a blower body. A support pipe 214 has an adjustment hole 222 at one end of a rod-shaped pipe and a support fitting 216 that protrudes perpendicularly to the axial direction of the pipe and has a mounting hole 215 at its tip is fixed to support and mount the blower body. Two mounting holes 215 are provided, and the mounting hole 215 is rotatably connected to the hole 220 at the upper end of the pipe 202 through the hole 218a and the hole 218b at the other end.
2 is the circular arc hole 221 of the angle adjustment table 213 and the bolt 21
9a and is fixed by a nut 219b.

In the above configuration, the support pipe 214 is fixed to the mounting location by passing a bolt or the like through the mounting hole 216, and the motor 209
When driven, rotational force is transmitted to the fan pulley 207 located on the pipe 202 side via the motor pulley 211 and the belt 212, which rotates the blade 208 fixed to the curved end of the rotating shaft 206 to blow air. Bolts 218a and nuts 218b supporting the support fitting 216 through holes 220 in the pipe 202, adjustment holes 222 at the lower end of the support pipe, and circular arc holes 221 in the angle adjustment table 213.
219a (Pole penetrating and fixing) 219a.

By loosening the nut 219b, the angle adjustment table 213 can be set at the required angle within the circular arc hole 221 with the bolt 218a as the fulcrum and the bolt 219a as the axis, and then fixed to blow air in the desired direction. It is.

Effects of the Invention As is clear from the description of the embodiments above, the present invention provides an orifice with a support beam extending across the orifice and projecting into the outer layer, fixing a propeller fan or motor to this, and fixing a propeller fan or motor to the support beam. Since it has a rotatable mounting bracket, it is easy to adjust the angle when installing the blower, and there is no need for a frame for mounting, which reduces the weight of the blower itself and reduces manufacturing costs. Practical effect: I am big 1
