Wherein, in the utility model, described material stirring conveying device 3 comprises frame 33, drum housing 34, conveyor screw 35, speed detector 36, reductor 37, the second motor 38, feed hopper 31, described frame 33 is arranged on car body 1, and back-up roller housing 34, described conveyor screw 35 is located in drum housing 34, described speed detector 36 connects conveyor screw 35 one end, described reductor 37 connects conveyor screw 35 other ends, described the second motor 38 connects reductor 37, described feed hopper 31 is located at one end of drum housing 34, the other end of drum housing 34 is offered described discharging opening 32.Described conveyor screw 35 comprises main shaft 351 and helical blade 352, and described main shaft 351 is erected in drum housing 34, and described helical blade 352 is sheathed on main shaft 351; Between the blade of ribbon spiral between two 352 of described conveyor screw 35, be provided with stirring rod (not shown).Make like this soil and adsorbent stir more even, and can clogging drum housing 34, stirring efficiency improved.
In the utility model, described magnetic separating device 7 comprises magnetic roll body 71 and for supporting the bracing frame (not shown) of magnetic roll body 71, described magnetic roll body 71 consists of magnetic cylinder 711 and several magnetospheres 712 that are contained on magnetic cylinder 711, the two ends of described magnetic cylinder 711 are provided with flange 713, described magnetosphere 712 is contained between two flanges 713, and the magnetic force face polarity between adjacent magnetosphere 712 is identical; On described magnetic cylinder 711 circumferential outer surfaces, be interval with complex root blend stop 714, described blend stop 714 has extended upward a plurality of poking bars 715.
Operation principle of the present utility model is as follows:
During soil conveying device 2 work due to the front of vehicle and then make soil enter soil cutting shovel 21, soil transmits to soil cutting shovel 21 rear portions via the first conveyer 22 again, reduced the resistance of motion of soil, avoid or reduced the situation of solid accumulation, material lifting device 23 is by the soil conveying of rising, can realize the breaker 4 that the soil of upper soll layer 100-300mm is sent to continuously to vehicle interior, 4 pairs of soil of breaker carry out fragmentation and are placed on material stirring conveying device 3, described breaker 4 comprises: casing 41, Stirring roller 42, semicircle sieve plate 43, the first motor 44 and receiving hopper 45, on described casing 41, offer a feeding mouth 46, described receiving hopper 45 is placed in the below of casing 41, and described Stirring roller 42 is placed in casing 41, and described the first motor 44 is placed on car body 1, and drives described Stirring roller 42 to be rotated, described semicircle sieve plate 43 two ends are fixed on casing 41, and be positioned at below Stirring roller 42, along the tangential direction of semicircle sieve plate 43 one end until feeding mouth 46 is filling a vertical sieve tray 47, between vertical sieve tray 47 and casing 41 inwalls, install adhesive tape curtain 48 together, described vertical sieve tray 47 upper ends are equipped with a vibrator 49, wet-soil-block falls into the Stirring roller 42 that high-speed rotary encloses, and the tup that wet-soil-block is turned agitating roller 42 smashes and loose splashing.Loose main direction of spattering is the tangential direction that smashes the circular trace that the tup of wet-soil-block rotates.Smashing the wet-soil-block flashing just in time has vertical sieve tray 47 to accept.Be splashed to the broken wet-soil-block on vertical sieve tray 47, granularity is less than just thoroughly sieve and the mistake of sieve aperture, and granularity is greater than sieve aperture and drops on the wet-soil-block at non-mesh place, because of the effect of vibrator 49, and strong the shake up and down of vertical sieve tray 47 and being shed on semicircle sieve plate 43.Because of tup and semicircle sieve plate 43 spacings very little, the wet-soil-block being shed on semicircle sieve plate 43 is subject to hammering again, because depositing nowhere coal in casing 41, can only all thoroughly be sieved after being pulverized.The saturating wet-soil-block after sieve, although particularly from vertical sieve tray 47, the wet-soil-block of sieve is not only wet but also sticky thoroughly, they drop on the saturating sieve wet-soil-block being sputtered and get to disorderly to tremble to touch and incessantly wave but on mutual disjunct adhesive tape curtain 48, just arrange downwards.Like this, wet-soil-block sample can not be bonded on sieve plate, can not be bonded on adhesive tape curtain 48, more can not be bonded on casing 41 walls by adhesive tape curtain 48, thereby assurance breaker is normally worked.From adhesive tape curtain 48, wet-soil-block landing and that thoroughly sieve, all falls in receiving hopper 45.This has just completed the shattering process of wet-soil-block.
Adsorbent is thrown in hopper 5 and is thrown in adsorbent simultaneously, adsorbent enters material stirring conveying device 3 with certain speed, the two enters adsorbent and broken soil uniformly in certain proportion thing material stirring conveying device 3 and stirs, magnetic adsorbent and soil are carried while being uniformly mixed to vehicle tail in material stirring conveying device 3, finally the afterbody in material stirring conveying device 3 falls on a second conveyor 6, the top of second conveyor 6 is magnetic separating devices 7, when the soil that is mixed with magnetic adsorbent was when second conveyor 6 sent body bottom, metal poking bar 715 can stir mixed material, make the soil that is bonded together further separated with adsorbent, the magnetic of being convenient to 71 pairs of magnetic adsorbents of magnetic roll body is attached, improve the efficiency of separation.When exercising the input operation of adsorbent, magnetic roll body 71 is inoperative, and the adsorbent mixing and soil are transported to after vehicle tail through second conveyor 6, directly enters on the ground, fills the part soil being scooped away, and makes soil layer return to original height.When exercising the reclaimer operation of adsorbent, start magnetic roll body 71, magnetic roll body 71 is with certain rotating speed rotation, the soil that is mixed with adsorbent carries by second conveyor 6 below that is sent to magnetic cylinder 711, magnetic adsorbent is attracted on magnetic roll body 71, magnetic roll body 71 is dumped in adsorbent recovery hopper 8 after rotating to a high position, thereby completes remediating heavy metal and pesticide contaminated soil.
Breaker of the present utility model is mainly applicable to the fragmentation of high-moisture percentage soil, due to the adhesive tape curtain of breaker with vibratile sieve plate and function of preventing material from being bound, no matter how high the moisture of broken pan feeding is, must not dry or dry, can blockage phenomenon after wet soil access arrangement.
The foregoing is only preferred embodiment of the present utility model, all equalizations of doing according to the utility model claim change and modify, and all should belong to covering scope of the present utility model.
