Abstract
The utility model discloses a variable-speed silo discharger comprising a main motor, a reducer, a delivery auger and a material trickling cone, wherein, the material trickling cone is arranged in the center of the bottom part of a silo, the main motor and the reducer are positioned below the material trickling cone, the output end of the reducer drives the delivery auger to rotate, the discharging opening of the delivery auger is communicated with the discharge port, the main motor is a multi-level variable-speed three-phase asynchronous motor, the output end of the main motor is in direct transmission with the input end of the reducer through a belt. The omission of a gear reducer from the variable-speed silo discharger results in a decline in the manufacturing cost, savings in space and a reduction of the number of fault points. The employment of the motor to directly drive the reducer has the effects of improving transmission efficiency and reducing running cost. The multi-level variable-speed motor can enable workers to control the silo discharger remotely, without leaving the master control room for in-laneway operation, thereby raising the level of the humanization and automation of the silo discharger.
Description
Technical field
The utility model relates to a kind of grain feed conveying machinery, particularly a kind of speed change bin discharger.
Background technology
The material of the interior long term storage of silo easily causes local fermentation and generates heat even go mouldy, and produces fire when serious; Rapeseed etc. are pushed easy fuel-displaced material, accumulate for a long time can cause going bad, and easily harden when delivering from godown, and flowing power is poor, is difficult for discharging.The material that bin discharger is used between delivering from godown of the interior material of silo and the storehouse group is had bad luck, bin discharger is installed on the silo below, comprise main motor, gear reduction box, reductor, conveying auger and drop down material awl, drop down the material awl and be arranged on silo bottom centre, main motor, gear reduction box and reductor are positioned at and drop down material awl below, main motor is connected with the input end of gear reduction box, gear reduction box is provided with the handle of transferring the files, the mouth of gear reduction box is connected with the input end of reductor by belt, the mouth of reductor drives conveying auger and rotates, the discharge gate of conveying auger is connected with discharging opening, electronic flashboard seals discharging opening, the free end of conveying auger is provided with engine installation, and in the conveying auger rotation, this engine installation promotes the line of centers revolution of conveying auger around silo.
When material need deliver from godown, open electronic flashboard, open discharging opening, start main motor, the handle of at this moment transferring the files is in Neutral Position, gear reduction box is not worked, stir the handle of transferring the files, make gear reduction box running, by belt pulley with transmission of power to reductor, the process reductor is decelerated to the rotating speed of demand, drives conveying auger and starts working.
Such bin discharger, when initial start, because the friction drag of material is very big, the handle that needs to transfer the files is allocated on the low rotation speed large torque gear, wait to start finish operation normal after, adjusting is transferred the files handle to normal speed, owing to the handle of transferring the files is arranged on the gear reduction box, when therefore regulating, the staff need pierce in the tunnel of silo below, and scraper plate machine or other load transfer device are installed in the tunnel, the space is narrow and small, work under bad environment; Itself costs an arm and a leg gear reduction box, is that a loss in efficiency point and fault take place frequently a little simultaneously, adds bulkyly, occupies lane space, be unfavorable for the installation of other equipment and damage after maintenance change.
The utility model content
For overcoming problems of the prior art, the utility model provides a kind of Long-distance Control of being convenient to, compact conformation, driving efficiency height, the speed change bin discharger that cost and operating cost are low.
For solving above technical matters, the technical solution of the utility model is, a kind of speed change bin discharger is provided, comprise main motor, reductor, conveying auger and drop down the material awl, drop down the material awl and be arranged on silo bottom centre that main motor and reductor are positioned at and drop down material awl below, the mouth of reductor drives conveying auger and rotates, the discharge gate of conveying auger is connected with discharging opening, and main motor is a change speed motor, and the input end of its mouth and reductor is by the belt through-coupling.
This speed change bin discharger has saved gear reduction box, has reduced cost, has saved the space, and has reduced the trouble point, and main motor direct-drive reductor improves driving efficiency, has reduced operating cost; The speed governing of change speed motor can realize the Master Control Room Long-distance Control, avoids manually entering the tunnel operation, has improved hommization, the automation level of bin discharger.
Change speed motor can be pole-changing multi-speed 3-phase asynchronous motor.
Change speed motor can be electromagnetic coupling asynchronous motor.
Change speed motor can adopt frequency converter to carry out speed control.
Pole-changing multi-speed 3-phase asynchronous motor is realized the adjusting of speed threshold by the number of pole-pairs that changes electrical motor; Electromagnetic coupling asynchronous motor carries out stepless time adjustment by the size that changes exciting current; Frequency converter is realized stepless time adjustment by the running frequency that changes electrical motor, and electricity saving performance is better.
Description of drawings
Fig. 1 is the structural representation of the utility model speed change bin discharger.
Among the figure: 1 electronic flashboard, 2 discharging openings, 3 main motors, 4 belts, 5 drop down material awl, 6 reductors, 7 conveying augers.
The specific embodiment
As shown in Figure 1, speed change bin discharger of the present utility model, comprise main motor 3, reductor 6, conveying auger 7 and drop down material awl 5, drop down material awl 5 and be arranged on silo bottom centre, main motor 3 is positioned at reductor 6 and drops down material awl 5 belows, main motor 3 is a change speed motor, the belt pulley of the belt pulley of its mouth and reductor 6 input ends is by belt 4 through-couplings, the mouth of reductor 6 drives conveying auger 7 and rotates, the discharge gate of conveying auger 7 middle discharging opening 2 bottom silo is connected, electronic flashboard 1 is with discharging opening 2 sealings, the free end of conveying auger 7 is provided with engine installation, in conveying auger 7 rotations, this engine installation promotes the line of centers revolution of conveying auger 7 around silo.Change speed motor can or adopt frequency converter to carry out speed control for pole-changing multi-speed 3-phase asynchronous motor, electromagnetic coupling asynchronous motor.Pole-changing multi-speed 3-phase asynchronous motor is realized the adjusting of speed threshold by the number of pole-pairs that changes electrical motor; Electromagnetic coupling asynchronous motor carries out stepless time adjustment by the size that changes exciting current; Frequency converter is realized stepless time adjustment by the running frequency that changes electrical motor, and electricity saving performance is better.
When material need deliver from godown, open electronic flashboard 1, open discharging opening 2, crawl is controlled the start button of main motor 3 in Master Control Room, and it is started on the gear of the big output torque of slow speed of revolution, and transmission of power to reductor 6 deceleration rear drive conveying augers 7 rotate.After startup finishes, main motor 3 is adjusted to high-revolving gear, makes conveying auger 7 normal operations, conveying auger 7 is discharged mass transport to discharging opening 2; The free end of conveying auger 7 is around the rotation of silo center simultaneously, and the rotation of conveying auger 7 is delivered from godown with the material of finishing jointly on the whole silo circumference around the revolution at silo center.
