In above-mentioned frequency conversion division system, preferably, described in sweep reduction device and comprise the column that is connected with variable-frequency motor and sweep scraper plate, sweep scraper plate and be connected on column and rotate with column; Described sweeping on scraper plate is provided with cylindrical connecting member, and this cylindrical connecting member is socketed on column, described cylindrical connecting member and column is provided with connecting bore and is bolted to connection.In the utility model, excessive, too small or need because of damage when changing only to need new scraper plate of sweeping to be arranged on column when sweeping scraper plate, column is reusable simple and fast while.
Above-mentioned frequency conversion division system, preferably, described division belt feeder is connected with variable-frequency motor and realizes stepless time adjustment by variable-frequency motor.
In the utility model, reduction device and division belt feeder employing variable frequency control will be swept in division process, make to sweep reduction device to the sweeping continuously of stream, evenly, number of times increases, substantially increase the degree of precision of reduction device, also achieve division ratio adjustment in a wider context simultaneously.
Above-mentioned frequency conversion division system, preferably, described even distributor comprises baffle plate and is arranged on the vertical rod of division belt feeder both sides, and described baffle plate is arranged in vertical rod and to the sense of motion of division belt feeder.When the stream on division belt feeder is uneven, places many for material on division belt feeder can be detained the few place of material and make stream relatively uniform by baffle plate, thus ensures the degree of precision of division.
Above-mentioned frequency conversion division system, preferred, described baffle plate top is provided with pipe link, and pipe link is plugged in the trepanning of rod end.Preferred, be connected by a spring between the middle part of described pipe link and the middle part of baffle plate.The flexible stream that makes when the stream on division belt feeder is excessive or have large lump material to enter on division belt feeder by spring entered even distributor; Can avoid material too much overstock at even distributor place, simultaneously division belt feeder can be protected not ground away by large part material.
Above-mentioned frequency conversion division system, preferably, described in keep sample bucket and rejected material bucket be all placed on electronic scale with the ratio that keeps sample of real-time detecting material stream.Simultaneously when regulating division ratio, operator can adjust and the variable-frequency motor sweeping reduction device and division belt feeder and be connected timely according to keep sample bucket and the data of electronic scale under rejected material bucket, thus conveniently mixes up division ratio.
Compared with prior art, the utility model has the advantage of: reduction device and division belt feeder employing variable frequency control will be swept in division process, make reduction device to the sweeping continuously of stream, evenly, number of times increases, even distributor makes the stream on division belt feeder even simultaneously; Substantially increase the degree of precision of reduction device.By arranging the easy to adjust, quick of division ratio that electronic scale makes below keep sample bucket and rejected material bucket.
