A kind of method of work of dedusting grain purchasing machine, step 1:Control module control divides grain pipe to turn on the switch, and then controls mould
Block controls exhaust fan and driving motor to open, and food sucking pipe starts to inhale grain, and grain is by food sucking pipe and grain pipe is divided to enter centrifuge tube;Step
Rapid two:When plane where the upper surface for the grain accumulated in centrifuge tube reaches sensor, timing unit starts to give centrifuge tube meter
When, control module control currently divides the switch of grain pipe to close, and control module controls another that the switch of grain pipe is divided to open;Step
Three:When timing unit reaches the time of setting, the gear door below centrifuge tube that control module control is timed is opened, timing list
First timing again, the grain in centrifuge tube enter grain container, when timing unit reaches the time of setting again, show in centrifuge tube
Grain completely into grain container, the gear door below control module control centrifuge tube is closed;Step 4:Sliding piece in outsourcing ring
It is moved on annular orbit;Thus by the switch of grain pipe being divided to open and close successively and the centrifuge tube with grain pipe is divided to connect
The opening of upper gear door and closing, do not only reach the purpose for inhaling grain, and also achieve the effect that dedusting.
The beneficial effects of the invention are as follows:Substantially increase dust removing effects.

Specific embodiment
Below by the description to embodiment, the shape of for example involved each component of specific embodiment of the invention, structure
It makes, the mutual alignment between each section and connection relation, the effect of each section and operation principle, manufacturing process and the side of operating with
Method etc., is described in further detail, completeer those skilled in the art to be helped to have inventive concept of the invention, technical solution
Whole, accurate and deep understanding.
A kind of dedusting grain purchasing machine, the dedusting grain purchasing machine include grain purchasing machine ontology 1, the control being arranged on grain purchasing machine ontology 1
Module, the driving motor 4 being arranged on grain container 2, multiple is arranged on grain storage at the grain container 2 being arranged on inside grain purchasing machine ontology 1
Centrifuge tube 3 on device 2 is arranged on dividing grain pipe 6, the exhaust fan 5 being arranged on point grain pipe 6, being arranged on a point grain for 3 upper end of centrifuge tube
On pipe 6 food sucking pipe 8 and food sucking pipe 8 is arranged on far from dividing the suction grain mouth of 6 one end of grain pipe.
Described point of grain pipe 6 is parallel with horizontal plane, and is mutually parallel between all points of grain pipes 6, adjacent point of any two
The distance between grain pipe 6 is equal.The both ends of point grain pipe 6 are respectively provided with a concentrate tube, food sucking pipe 8 and exhaust fan 5 respectively with two
Concentrate tube connects.
Described point of grain pipe 6 is equipped with switch close to one end of food sucking pipe 8, and switch is connect by conducting wire with control module.It drives
Dynamic motor 4 and exhaust fan 5 are connect respectively by conducting wire with control module.
The centrifuge tube 3 is parallel with horizontal plane, and is mutually parallel between all centrifuge tubes 3, any two it is adjacent from
The distance between heart pipe 3 is equal.The upper end of centrifuge tube 3 is equipped with sensor, and 3 lower end of centrifuge tube is equipped with gear door, usually keeps off door and is in
Closed state, keeps off door and sensor is connect by conducting wire with control module.
The surface of the centrifuge tube 3 is equipped with the dust escape hole that multiple diameters are less than grain diameter, due to the weight of dust
Less than the weight of grain, when centrifuge tube 3 rotates, the grain in centrifuge tube 3 is in the lower section grain of centrifuge tube 3 mostly
Comprising dust be in the top of centrifuge tube 3 mostly, in order to increase the efficiency that dust is detached with grain, dust hole of escaping exists
The distribution density on 3 top of centrifuge tube is much larger than distribution density of the dust escape hole in 3 lower part of centrifuge tube.
Grain is detached by exhaust fan 5 in order to prevent, and the position that the exhaust fan 5 is connect with concentrate tube is equipped with demarcation strip, institute
Demarcation strip is stated equipped with venthole, the diameter of the venthole is less than the diameter of grain, while venthole can allow dust to lead to
It crosses, has the function that part dedusting.
In order to further increase the effect of dedusting, the food sucking pipe 8 is equipped with dust bin, and dust bin is equipped with preliminary dust suction
Hole, the outside of dust bin are enclosed with outsourcing ring 9, and outsourcing ring 9 is equipped with cleaning shaft 7, cleaning shaft 7 far from outsourcing ring 9 one
End is connect with exhaust fan 5, and the dust inside food sucking pipe 8 is drawn by the draft effect of exhaust fan 5.Preliminary air suction opening in order to prevent
It is blocked by the grain inside food sucking pipe 8, annular orbit is equipped in the outsourcing ring 9, annular orbit is equipped with to be transported around annular orbit
Dynamic sliding piece, the sliding piece are bonded with the external of dust bin, and the width of sliding piece is much smaller than the length of the circumference of dust bin,
When sliding piece moves, suction can be lost with the preliminary air suction opening of sliding piece contact site in dust bin, so that being drawn
The grain that is moved in gravity and food sucking pipe 8 of grain take away, maintain the unimpeded of preliminary air suction opening.
In order to reduce influence of the cleaning shaft 7 to 8 suction of food sucking pipe, the cleaning shaft 7 is much smaller than food sucking pipe 8 so far
Diameter.
Timing unit is additionally provided in the control module.Synchronization, only there are one be to beat for the switch on all points of grain pipes 6
It opens, the gear door of centrifuge tube 3 is in normally off.
A kind of method of work of dedusting grain purchasing machine, step 1:Control module control divides grain pipe 6 to turn on the switch, and then controls
Module controls exhaust fan 5 and driving motor 4 to open, and food sucking pipe 8 starts to inhale grain, grain by food sucking pipe 8 and divide grain pipe 6 enter from
Heart pipe 3;Step 2:Where the upper surface for the grain accumulated in the centrifuge tube 3 reaches sensor during plane, timing unit start to
3 timing of centrifuge tube, control module control currently divide the switch of grain pipe 6 to close, and control module controls another to divide the switch of grain pipe 6
It opens;Step 3:When timing unit reaches the time of setting, control module controls the gear door of 3 lower section of centrifuge tube being timed
It opens, timing unit timing again, the grain in centrifuge tube 3 enters grain container 2, and timing unit reaches the time of setting again
When, show the grain in centrifuge tube 3 completely into grain container 2, the gear door of 3 lower section of control module control centrifuge tube is closed;Step
Four:Sliding piece in outsourcing ring 9 moves on annular orbit;Thus by the switch of grain pipe 6 is divided to open and close successively and
With dividing the opening of gear door and closing on the centrifuge tube 3 that grain pipe 6 connect, the purpose for inhaling grain is not only reached, and also reach dedusting
Effect.
