Axle is connected with motor 6, and two the first output shafts and second output shaft, two the second output shafts point are provided with transmission case 1
It is not connected with a pair of screw rods 4, the second output shaft is connected with agitating paddle 5.
A pair of screw rods 4 be arranged in parallel, and the two ends of screw rod 4 pass the front-rear side walls of hopper 2, one end of screw rod 4 and biography respectively
The first output shaft connection of dynamic case 1, the other end extends to discharging opening 3.Agitating paddle 5 is arranged on the top of a pair of screw rods 4, agitating paddle
Agitating shaft is provided with 5, one end of agitating shaft passes the rear wall of hopper 2 and is connected with the second output shaft of transmission case 1.
As shown in figure 3, be provided with variable transmission mechanism in transmission case 1, the variable transmission mechanism include drive gear 101,
Two the first output gears 103, the second output gear 106 and the first ratchet 102, the second ratchet 104 and transition
Gear 105.Drive gear 101 is arranged on input shaft, is driven by motor 6.Two the first output gears 103 are separately mounted to two
On individual first output shaft, the second output gear 106 is arranged on the second output shaft.
First ratchet 102 is arranged on the axle of drive gear 101, and one-way clutch is provided with the first ratchet 102
Bearing, two the first output gears 103 are arranged on the top of the first ratchet 102 and engaged with the first ratchet 102, the
Two ratchets 104 are arranged on the top of two the first output gears 103 and engaged with the first output gear 103, the second output
Gear 106 is arranged on the top of the second ratchet 104 and engaged with the second ratchet 104；Transition gear 105 is arranged on drive
The top of moving gear 101 and engaged with drive gear 101, the second ratchet 104 is arranged on the axle of transition gear 105, the
Two ratchets 104 are internally provided with one-way clutch bearing.
When motor 6 is rotated forward, drive gear 101 is rotated forward, the one-way clutch bearing and drive gear of the first ratchet 102
101 axles are engaged, and the first ratchet 102 follows drive gear 101 together to rotate；The one-way clutch axle of second ratchet 104
Hold and depart from the axle of transition gear 105, the second ratchet 104 will not follow transition gear 105 to rotate, and transition gear 105 does not rise
Gearing.First ratchet 102 drives two the first output gears 103 to rotate, the drive screw 4 of the first output gear 103
Rotate, the first output gear 103 drives the second output gear 106 to rotate by the second ratchet 104, the second output gear
106 driving agitating paddles 5 are rotated.
Transmission speed ratio now is：
If：The number of teeth of drive gear 101 is z1, and the number of teeth of the first ratchet 102 is z2, and the number of teeth of the first output gear 103 is
Z3, the number of teeth of the second ratchet 104 is z4, and the number of teeth of transition gear 105 is z5；The number of teeth of second output gear 106 is z6；
Then：4 rotating speeds of screw rod/6 output speeds of reducing motor=z2/z3
5 rotating speeds of agitating paddle/4 rotating speeds of screw rod=z3/z6
When motor 6 is inverted, drive gear 101 is inverted, the one-way clutch bearing and drive gear of the first ratchet 102
101 axles depart from, and the first ratchet 102 will not follow drive gear 101 together to rotate, and the first ratchet 102 does not play transmission
Effect；The one-way clutch bearing of second ratchet 104 is engaged with the axle of transition gear 105, and the second ratchet 104 follows transition
Gear 105 is rotated.Drive gear 101 drives transition gear 105 to rotate, and the second ratchet 104 follows 105 turns of transition gear
Dynamic, the second ratchet 104 drives the first output gear 103 and the second output gear 106 to rotate simultaneously, so that drive screw 4
Rotated with agitating paddle 5.
Transmission speed ratio now is：
If：The number of teeth of drive gear 101 is z1, and the number of teeth of the first ratchet 102 is z2, and the number of teeth of the first output gear 103 is
Z3, the number of teeth of the second ratchet 104 is z4, and the number of teeth of transition gear 105 is z5；The number of teeth of second output gear 106 is z6；
Then：The output speed of 4 rotating speeds of screw rod/reducing motor 6=(z1/z5) * (z4/z3)
5 rotating speeds of agitating paddle/4 rotating speeds of screw rod=z3/z6
It can be seen that：The direction exported regardless of motor 6, the feeding direction of screw rod 4 is constant, while agitating paddle 5
Steering it is also constant；Because being, by the transition of transition gear 105, power, transition tooth to be transmitted to screw rod 4 when motor 6 is reversely exported
The number of teeth of wheel 105 is greater than the number of teeth of drive gear 101 and the number of teeth of the first ratchet 102, therefore is reversely exported in motor 6
When, screw rod 4 has obtained lower rotating speed when being rotated forward compared to motor 6.Under some rotating speed of motor 6, if changing turning for motor 6
To then screw rod 4 can obtain different rotating speeds, i.e., different delivery rates.
The variable transmission mechanism of the present invention sets two ratchets, and different ratchets obtains different when working
Output speed.In industrial quantitative ingredient, when motor 6 is operated in power frequency supply, by the rotating speed of the change motor 6 of low cost,
Fast, slow two kinds of delivery rates can be realized, the frequency converter using higher costs is eliminated.When constant flow is fed, motor 6 is accessed
During speed regulator, by the steering for changing motor 6, it is possible to achieve high and low two sections of speed adjustable range, the control to delivery rate is expanded
Scope processed.
Using the above-mentioned desirable embodiment according to the present invention as enlightenment, pass through above-mentioned description, related staff
Various changes and amendments can be carried out in without departing from the scope of the present invention completely.The technical scope of this invention is not
It is confined to the content on specification, it is necessary to its technical scope is determined according to right.
