Abstract
The utility model provides a tuyere adjusting device which comprises a wind deflector in the interior of a pipeline, wherein two bearings are symmetrically arranged on the outer side of the pipeline, rotating shafts are mounted in bearings in a matched mode, and the wind deflector is fixedly connected with the rotating shaft in the pipeline, and a torque reset spring is connected with one end of the rotating shaft in the exterior of the pipeline, and the other end of the rotating shaft in the exterior of the pipeline is connected with a stress rod which is matched with a rotatable I-shaped drive swing arm, a middle position of a connecting rod of the I-shaped drive swing arm is connected with a transmission shaft, and a transmission device is connected with the transmission shaft. The tuyere adjusting device is provided with a wind adjusting device which can freely control the strength of the wind by controlling of the size of a tuyere in a conveying pipeline, and at the same time, can also save energy, and enables cotton to be conveyed orderly.
Description
Technical field
The utility model relates to cottonseed, cotton manufacture field, relates in particular to a kind of air port control apparatus for the cotton delivery duct.
Background technology
At present, in unginned cotton, cottonseed processing process, no matter be unginned cotton or the conveying of gined cotton, nearly all be to carry in transport pipeline by the negative pressure wind of blower fan manufacturing, when the unginned cotton in carrying or gined cotton equivalent are more, need to have enough large wind-force could realize fast circulation, but when operational throughput hour, adopt excessive wind-force to carry, not only cause the waste of wind-force, also be unfavorable for orderly the carrying of cotton simultaneously.
Summary of the invention
The technical problems to be solved in the utility model is for the existing weak point of prior art, provide a kind of size by air port in the control delivery duct freely to control the wind regulating device of wind-force size, simultaneously all right energy savings, and can allow cotton carry in order.
Technical solution of the present utility model is, following a kind of air port control apparatus is provided, the air baffle that comprises pipe interior, the described pipeline outside is provided with two bearings that are arranged symmetrically with, be fitted with rotating shaft on the described bearing, fixedly be connected to air baffle in the rotating shaft of described pipe interior, rotating shaft one termination of described pipeline external has the moment of torsion retracing spring, the other end is connected to force rod, described force rod drives swing arm with rotatable I-shape and cooperates, pipe link midway location and transmission shaft that described I-shape drives swing arm join, and are connected to driving device on the described transmission shaft.
Adopt above technical scheme, the utility model rotatablely moves by the driving swing arm on the driving device, drive the rotation of force rod, thereby under the rotation of rotating shaft, driving inner air baffle rotates, the air port is opened, because driving swing arm rotates, drive again swing arm institute rotation distance greater than the length of force rod, so make when the driving swing arm does not apply power to force rod, rotating shaft resets under the effect of moment of torsion retracing spring, and the air baffle air port of pipe interior is closed, by the rotating speed of control driving device, can control the opening time of pipe interior air baffle, by the length that bar is accepted in adjusting, can control the openings of sizes of air baffle, result of use is better in the actual production.
As preferably, described driving device comprises electrical motor, be installed in the small belt pulley on the motor main shaft, the big belt pulley that links to each other with small belt pulley by belt, big belt pulley be installed on the worm screw, described worm screw is fixed on the support by bearing, connected worm gear on the described worm screw, described worm gear is fixed on the transmission shaft, and described transmission shaft is connected with support by bearing, and described transmission the tip of the axis is connected with the driving swing arm.
Adopt the technical program, because the rotating speed of electrical motor is very fast, can reduce the rotating speed of electrical motor by the transmitting ratio of large small pulley existence, in like manner, Worm Wheel System also plays the reduction of speed effect, uses in addition belt wheel to carry out transmission, even if air baffle causes and can not work owing to external factor, whole device continues the harm that transmission brings, be that electrical motor is rotated further, outside whole transmission device is stuck, forces electrical motor to force stall, this moment, the motor interior electric current sharply increased, and burnt electrical motor.
