Abstract
The present utility model discloses a kind of fan used in flue-cured tobacco which includes an electric motor, a drive shaft, a bearing block and blades, the output shaft of said electric motor connects directly to the upper end of said drive shaft through the shaft coupling, and said blades are fixed at the bottom of the drive shaft. The drive shaft has good stability, since the present utility model uses direct-drive mode and the drive shaft is driven directly by the electric motor. The present utility model also has a diesel engine which can drive the fan so as to make the baking of tobacco leaf continue normally when there is a power cut. The total equipment is with advantages of easy disassembly and assembly, convenient maintenance and high reliability while it is used.
Description
Technical field
The utility model relates to the blower fan that a kind of baking tobacco leaves is used.
Background technique
Quality when the quality of Flue-cured tobacco Quality depends on tobacco first baking to a great extent.By blower fan hot blast is blasted in the flue-cured tobacco house during tobacco grower's flue-cured tobacco, to take away the moisture in the tobacco leaf.The blower fan that present tobacco grower generally uses is to adopt motor to drive transmission shaft by the bel-drivenn mode to rotate and then drive the fan blade rotation.Because the transmission shaft that the output shaft of motor and drive fan blade rotate is not on same center line, therefore poor stability during transmission, make the bearing wear on the transmission shaft get terribly, make bearing heating, hot, not only power consumption also needs often to change bearing, and this blower fan runs into when having a power failure and just can't use, therefore can't guarantee the baking quality of fresh tobacco leaf, cause very big economic loss to the tobacco grower.
The model utility content
The utility model aims to provide a kind of good stability, flue-cured tobacco blower fan that energy consumption is low.
Another purpose of the present utility model is to solve the technical problem that can't use when existing blower fan has a power failure.
The technological scheme that the utility model adopted is: a kind of flue-cured tobacco blower fan, comprise motor, transmission shaft, bearing support, fan blade, transmission shaft is arranged in bearing support, the top and the bottom of transmission shaft are provided with bearing, fan blade is fixed on the bottom of transmission shaft, it is characterized in that: the output shaft of motor is fixedlyed connected with the upper end of transmission shaft by coupling.
Described flue-cured tobacco is with also comprising diesel engine in the blower fan, the side circumference of coupling is provided with annular groove, is provided with the belt of ring-type in the groove, and the other end of annular belt is socketed on the belt pulley of diesel engine.
Described coupling is made up of upper coupling and following coupling, the bottom of upper coupling is a pawl formula structure, the upper-end surface of following coupling is provided with and the corresponding groove of the pawl of upper coupling, the pawl of upper coupling places down in the groove of coupling upper-end surface, the output shaft of motor is fixedlyed connected with upper coupling, and following coupling is fixedlyed connected with the upper end of transmission shaft.
Also be provided with buffer stopper between the described upper and lower coupling, buffer stopper is arranged in the groove of coupling down.
The described side circumference of coupling down is provided with bipassage ring connected in star up and down, is equipped with the belt of ring-type in the per pass groove, and the other end of annular belt is socketed on the belt pulley of diesel engine.
The belt that wears in the described groove is a v belt.
Described motor is for becoming the level multispeed motor.
The beneficial effects of the utility model are: one, the output shaft of motor is directly fixedlyed connected with the upper end of transmission shaft by coupling, the change indirect drive is direct transmission, therefore the good stability during transmission, the reliability height, bearing on the transmission shaft is difficult for being worn, it is hot can not generate heat when transmission shaft rotates, long service life; Two, dispose diesel engine in the blower fan, the belt pulley of diesel engine is connected with coupling on the blower fan by belt, when running into power failure, can use diesel engine directly to drive blower fan and rotate, avoid causing normally baking tobacco leaves, cause the tobacco grower to be subjected to unnecessary loss owing to having a power failure; Three, becoming the level multispeed motor can be according to required blast of different baking stages of tobacco leaf, the motion speed that air quantity is adjusted blower fan, but using electricity wisely reduces the tobacco flue-curing cost; Four, whole device easy to disassemble and assemble is easy to maintenance.
