Abstract
The utility model belongs to a driving belt automatic tensioning device of a fowl greenhouse ventilation machine. According to the scheme which is provided by the utility model, the center part of a framework is provided with a drive assembly which is provided with a blade and a large belt pulley of the drive assembly is connected to a small belt pulley which is arranged on a motor through a driving belt. The driving belt automatic tensioning device of a fowl greenhouse ventilation machine is characterized in that the motor is arranged on the framework which is arranged on the upper right part of the drive assembly, when the driving belt in use, a loose edge in a relaxed state is arranged on the upper part, the framework is provided with a tension wheel for pressing the loose edge. The driving belt automatic tensioning device of a fowl greenhouse ventilation machine has the advantages that a freely rotated roller is fixed to a swing arm through a torsion spring or torque T of the tension spring which acts on the swing arm, the roller acts on the loose edge of the belt owing to pressure F which is generated by the torque for realizing automatic tensioning of the driving belt.
Description
Technical field
The utility model belongs to a kind of poultry, the greenhouse ventilation automatic takeup with driving belt on the blower fan.
Background technology
At present, known poultry, greenhouse ventilation are with the tensioning apparatus on the blower fan, mainly contain following several form: 1, the microscler fixing hole that electromotor is installed is set on the framework of blower fan, when needs are regulated the tightness of belt, unclamp and mobile bolt in microscler fixing hole, regulate the position of electromotor, when the tightness of belt is met the requirements, tight a bolt again; 2,, during electromotor work, realize tensioning by the deadweight of electromotor and the effect of extension spring with the outer end of motor mounting in a cantilever.The problem that these regulative modes exist is: when leaning on the tensioning state of microscler fixing hole manual adjustments belt, and inconvenient operation, the degree of tightness of belt is wayward, can shorten belt life simultaneously, reduces work of maintenance personnel efficient; When utilizing the effect of the deadweight of electromotor and extension spring to realize auto-tensioning, electromotor is positioned on the air inlet, therefore can influence air intake, in addition, because electromotor is fixing, thereby has reduced the reliability etc. of equipment, sees figure.
Summary of the invention
For overcome tensioning apparatus on existing poultry, the greenhouse ventilation machine by microscler fixing hole, manual adjustments realizes tensioning, inconvenient operation, the belt degree of tightness is wayward, reduces belt life; Motor is positioned on the air inlet, influence air intake, and motor is unfixing, the deficiencies such as reliability of reduction equipment, the utility model provide a kind of poultry, greenhouse ventilation machine driving belt automatic takeup, and this device not only can be realized auto-tensioning, handled easily, improve belt life, and, can not influence intake because volume is less.
According to scheme provided by the utility model, driven unit is installed at center at framework, blade is installed on driven unit, small belt pulley on the big belt pulley of driven unit utilizes driving-belt and is installed on electromotor is connected, it is characterized in that: motor mounting is on the top-right framework of driven unit, driving-belt is installed a regulating wheel that is used to push down the slack list on framework on the slack list that work the time is relaxed state is positioned at.
Column is installed on framework, hinged swing arm on column, regulating wheel is connected in the outer end of swing arm.Overlap torsion spring on the jointed shaft of hinged swing arm and framework, an end of torsion spring is connected with column, and the other end is connected with swing arm.Between swing arm and framework, extension spring is set.
The beneficial effects of the utility model are, the moment T by a torsion spring or extension spring acts in the swing arm, fixes a roller free to rotate in the swing arm, and the pressure F that this roller produces because of moment acts on the slack list of belt, realizes the auto-tensioning of driving belt.

Fig. 2 is original another kind of blower fan structure figure.
Fig. 3 is a structure chart of the present utility model.
Fig. 4 is strainer figure of the present utility model.
Embodiment
As shown in the figure: the driven unit 10 that blower fan is installed at the center of framework 9, on driven unit 10, blade is installed, small belt pulley 2 on the big belt pulley 7 of driven unit 10 utilizes driving-belt and is installed on electromotor 1 is connected, electromotor 1 is installed on the driven unit 10 top-right frameworks 9, driving-belt is installed a regulating wheel 5 that is used to push down slack list 3 on framework 9 on the slack list 3 that work the time is relaxed state is positioned at.During work, the small belt pulley 2 on the electromotor 1 rotates by the big belt pulley 7 that driving-belt drives on the driven unit 10, and driven unit 10 drives its blade high speed rotating, drains into indoor vitiated air outdoor.During rotation, above the slack list 3 of driving-belt is positioned at, below its pilled-in selvedge 4 is positioned at, electromotor 1 all rotates with counter clockwise direction with driven unit 10, after rotating certain time limit, belt can relax, owing to have roller pressing on the slack list 3 of driving-belt, therefore can automatically driving-belt be compressed, make driving-belt locate the degree of tightness state of predicting all the time.Usually below all the slack list 3 of driving-belt being arranged in traditional blower fan, above pilled-in selvedge 4 was placed on, in order to avoid in the operation process, after slack list 3 was lax, slack list 3 toward sagging, with pilled-in selvedge 4 mutual collision frictions, influenced the work of driving-belt, therefore under the deadweight effect.Usually all arrange in mode shown in Figure 1, in this case, in case when the slack list 3 that driving-belt occurs is too lax, just can only be by the position of adjustment electromotor 1, the degree of tightness of regulating driving-belt, cumbersome.
Hinged swing arm 6 on column 8, regulating wheel 5 is connected in the outer end of swing arm 6.Cover torsion spring 12 on the jointed shaft 11 of hinged swing arm 6 and framework 9, an end of torsion spring 12 and column 8 are fixing, and the other end is connected with swing arm 6.Or extension spring is set in swing arm 6 and 9 of frameworks.Utilize torsion spring or elastic force that extension spring produced, make the regulating wheel 5 that is positioned at swing arm 6 outer ends when blower fan is worked, with certain defeating on the slack list 3 of driving-belt, guarantee the operate as normal of driving-belt all the time.
