Beginning back and forth movement, earthworm excrement and earthworm are scraped off by sludge scraper component in the lump during back and forth movement, in some instances it may even be possible to water occur
Flat scraper plate cuts away the situation of earthworm, causes substantial amounts of earthworm dead.The work that earthworm and earthworm excrement are separated is time-consuming, although
There are many processing methods in report, but efficiency is not high.The present invention only wipes earthworm excrement off to reach, keeps the purpose of earthworm here,
Take following working method：By 15~20 days, after the complete sludge of dealing with earthworm, add new a collection of 15 again in casing 6~
Mud mixture after 20cm.Now, the thickness of sludge and earthworm excrement is added up in 30~35cm or so in casing 6.Earthworm smells
Feel very sensitive, gradually climb in new sludge blanket, in order to be further ensured that earthworm climbs to upper strata, open wind regime and wait 1.0~
2.0 hours, because earthworm likes quiet environment, earthworm will be far from bottom and be transferred to new sludge blanket region.Now, open convex
The driving cam 10 of wheel drive motor 11 rotates, and cam 10 carries out back and forth movement process by the driving sludge scraper component of connecting rod 9
In, gradually the sludge (earthworm excrement) handled is scraped off, until all sludge (earthworm excrement) handled have been scraped.Due to scraper plate rail
The presence in road 8, ensure that sludge scraper component is run by the track of design.Earthworm excrement is all collected in belt by earthworm dustpan 3
On conveyer 1, finally see off to earthworm excrement collecting region., it is necessary to be important to note that earthworm in using dealing with earthworm sludge process
There is the habit of the different halls of grandparent and grandchild, such as aperiodically redistribute earthworm, can also cause the situation of inbred so that population moves back
Change, influence Treatment of Sludge effect.The earthworm excrement finally given by dealing with earthworm sludge is splendid fertilizer.Therefore, the above
It is sludge reduction, stabilisation, innoxious, recycling process using the whole process of dealing with earthworm sludge.
