The utility model, in order to overcome the deficiencies in the prior art, provides the earthworm that utilizes that a kind of cost is low, separating rate is fast to produce the environment-protecting cultivation device of saline-alkali soil modifying agent.
To achieve these goals, the utility model is by the following technical solutions:
A kind of environment-protecting cultivation device utilizing earthworm to produce saline-alkali soil modifying agent, described device entirety is in tubular, comprise housing (1) and be located at least two vermiculture boxes (2) in housing (1), it is characterized in that: screen cloth (21) is formed on the bottom of described vermiculture box (2), be provided with one in the below of screen cloth and draw flitch (22), the described flitch (22) that draws is in taper upwards, also comprise a declutch shaft (3) that can rotate under power set effect, draw flitch (22) and to be set on this declutch shaft (3) and can vertically movement on declutch shaft, on declutch shaft, the top of screen cloth (21) is also connected with a separation brush (4) that can rotate with declutch shaft (3), the upper end of described housing (1) is provided with top cover (11), the feed bin (12) that can hold separated compost is formed at the bottom of housing (1), feed bin (12) offers discharging opening (12a).By forming screen cloth in the bottom of breeding box, the below of screen cloth is arranged in drawing flitch to upper conical, and the separation brush that can rotate with declutch shaft, thus when vermiculture, screen cloth with draw the bottom that flitch forms breeding box jointly; When earthworm is separated with compost, draws flitch and be separated with screen cloth, meanwhile, be separated brush and rotate under declutch shaft drives, swipe compost; The compost be separated drops in the feed bin of lower housing portion via the flitch that draws of taper; At least two vermiculture boxes are vertically set in housing, can space be made full use of.Therefore, the utility model compact conformation, vermiculture is effective, and separating rate is fast, reduces labor workload.
Further, described separation brush (4) comprises the collar (41) being sheathed on declutch shaft (3) and the brush bar (42) be evenly arranged along the collar (41) circumference, and brush bar (42) surface is evenly equipped with bristle, and the collar (41) is opened by a buckle structure and locked.When needs are separated earthworm and compost, be set on declutch shaft by separation brush, declutch shaft rotates under the effect of power set, thus realizes being separated of compost and earthworm, structure simply, good separating effect.
Further, described housing (1) is provided with can the gallery ports (13) of folding, and top cover (11) is provided with transom (11a).Opposing seal, lighttight space, is applicable to the Growth and reproduction of earthworm; Meanwhile, be convenient to reinforced and observe.
Further, also comprise an automatic spraying device, the electrically operated valve that this automatic spraying device comprises the shower (5) be arranged on vermiculture box (2) inwall, control shower (5) opens and closes, the diapire of vermiculture box (2) is provided with the humidity sensor for detecting soil moisture, the output of humidity sensor is connected with a control device, and control device exports the keying that control signal controls described electrically operated valve.Automatically can detect the humidity of compost, and by control device control shower compost is sprayed water, moistening, make the moistening degree of compost be in the optimum range of vermiculture all the time, reduce manual intervention degree, improve the efficiency of vermiculture.
Further, described power set are servomotor.Control accurately, effective.
Therefore, the utility model compact conformation, vermiculture is effective, and separating rate is fast, reduces labor workload, can be used for preparing saline-alkali soil modifying agent.

Embodiment
In order to make those skilled in the art person better understand the utility model scheme, below in conjunction with the accompanying drawing in the utility model embodiment, clear, complete description is carried out to the technical scheme in the utility model embodiment.
As Figure 1-3, the environment-protecting cultivation device utilizing earthworm to produce saline-alkali soil modifying agent of the present utility model, described device entirety is in tubular, at least two the vermiculture boxes 2 comprising housing 1 and be located in housing 1, screen cloth 21 is formed on the bottom of vermiculture box 2, the below of screen cloth is provided with one and draws flitch 22, draw flitch 22 in taper upwards, also comprise a declutch shaft 3 that can rotate under power set effect, draw flitch 22 and to be set on this declutch shaft 3 and can vertically movement on declutch shaft, on declutch shaft, the top of screen cloth 21 is also connected with a separation brush 4 that can rotate with declutch shaft 3, the upper end of described housing 1 is provided with top cover 11, the feed bin 12 that can hold separated compost is formed at the bottom of housing 1, feed bin 12 offers discharging opening 12a.As shown in Figure 3, be separated brush 4 and comprise the collar 41 being sheathed on declutch shaft 3 and the brush bar 42 be evenly arranged along the collar 41 circumference, brush bar 42 surface is evenly equipped with bristle, and the collar 41 is opened by a buckle structure and locked.Housing 1 is provided with can the gallery ports 13 of folding, and top cover 11 is provided with transom 11a, and described power set are servomotor.
As preferably, the present embodiment also comprises an automatic spraying device, this automatic spraying device comprises the shower 5 be arranged on vermiculture box 2 inwall, controls the electrically operated valve of shower 5 keying, the diapire of vermiculture box 2 is provided with the humidity sensor for detecting soil moisture, the output of humidity sensor is connected with a control device, and control device exports the keying that control signal controls described electrically operated valve.Automatically the humidity of compost is detected by humidity sensor, and by control device control shower compost is sprayed water, moistening, make the moistening degree of compost be in the optimum range of vermiculture all the time, reduce manual intervention degree, improve the efficiency of vermiculture.
The utility model is by forming screen cloth in the bottom of breeding box, and the below of screen cloth is arranged in drawing flitch to upper conical, and the separation brush that can rotate with declutch shaft, thus when vermiculture, screen cloth with draw the bottom that flitch forms breeding box jointly; When earthworm is separated with compost, draws flitch and be separated with screen cloth, meanwhile, be separated brush and rotate under declutch shaft drives, swipe compost; The compost be separated drops in the feed bin of lower housing portion via the flitch that draws of taper, namely realizes being separated of compost and earthworm; Compact conformation, vermiculture is effective, and separating rate is fast.
Obviously, described embodiment is only a part of embodiment of the present utility model, instead of whole embodiments.Based on the embodiment in the utility model, those of ordinary skill in the art are not making the every other embodiment obtained under creative work prerequisite, all should belong to the scope of the utility model protection.
