Detailed description of the invention
Below in conjunction with the drawings and specific embodiments, the present invention is described in further detail.
As depicted in figs. 1 and 2, seabed of the present invention cobalt bearing crust fragmentation gathers integrated apparatus, comprise and be installed on disruption elements 1 on undersea mining car 3 and collection assembly 2, undersea mining car 3 can adapt to seabed cobalt bearing crust orographic condition, it is prior art, disruption elements 1 comprises support 11, be installed on the crushing roller 12 below support 11 and the rotary drive 13 for driving crushing roller 12 to rotate, support 11 is installed on undersea mining car 3 by an elevating mechanism 4, the motion of disruption elements 1 integral elevating can be ordered about by elevating mechanism 4, thus regulate the degree of depth of the broken cobalt bearing crust of crushing roller 12, collection assembly 2 comprises pump 21 and gathers cover 22, the entrance of pump 21 is by pipeline and the inner space gathering cover 22, gather cover 22 cover at the outside of crushing roller 12 and be provided with the lower ending opening 221 stretched out for crushing roller 12 in lower end.During work, rotary drive 13 drives crushing roller 12 to rotate broken cobalt bearing crust, by the degree of depth of the broken cobalt bearing crust ore bed of the adjustable crushing roller of elevating mechanism 4 12, gather cover 22 to gather the cobalt bearing crust after fragmentation, in time the cobalt bearing crust gathered in cover 22 can be collected by the water suction effect of pump 21, cobalt bearing crust powder collection under fragmentation stripping can get up by this device while broken cobalt bearing crust, the combination that after achieving seabed cobalt bearing crust fragmentation and fragmentation, cobalt bearing crust gathers, can greatly increase work efficiency, and its structure is simple, be easy to make, collecting efficiency is high, working stability is reliable.
In the present embodiment, gather cover 22 and be vertically slidedly arranged on support 11, on support 11, be specifically provided with the chute vertically arranged, gather on cover 22 and be connected with slide block, slide block is slidedly arranged in chute, and collection cover 22 can be free to slide by the vertical direction.The lower end gathering cover 22 is provided with and is bearing in gathering cover 22 slide plate 23 slided on ore bed surface, and slide plate 23 is provided with two pieces, and two pieces of slide plates 23 are divided into the both sides gathering cover 22 line of travel; Each slide plate 23 comprises dull and stereotyped two arcs upwarped with being connected to dull and stereotyped rear and front end.When normally working, slide plate 23 and ore bed surface contact also support and gather cover 22, the lower ending opening 221 of collection cover 22 is fitted with ore bed surface all the time, gather cover 22 can not increase with crushing roller 12 grinding depth and decline, avoid and cause interference when moving ahead fragmentation, also be that broken cobalt bearing crust can not be run out of from collection cover 22 simultaneously, be beneficial to the Efficient Collection of cobalt bearing crust; And when sea-floor relief changes, gather cover 22 and slided along ore bed surface by slide plate 23, the change of seabed mima type microrelief can be adapted to.
In the present embodiment, crushing roller 12 is spiral pick cylinder, and rotary drive 13 is motor.Spiral pick cylinder is arranged on support 11 by bearing support, and the output shaft of motor is connected with spiral pick cylinder, and then drives spiral pick cylinder to rotate.
In the present embodiment, support 11 is also connected with undersea mining car 3 by a parallelogram oscillating machine structure, parallelogram oscillating machine structure comprises two forks 5, the two ends of each fork 5 are articulated with on support 11 and undersea mining car 3 respectively, two fork 5 length is consistent and be parallel to each other, and such two forks 5, forms a parallel-crank mechanism between support 11 and undersea mining car 3.Elevating mechanism 4 driving arm 11 can make support 11 relative to the elevating movement of undersea mining car 3 under the restriction of draft link 5, and this structure can improve installation stability and the reliability of disruption elements 1.The elevating mechanism 4 of the present embodiment comprises the hinged lift telescopic cylinder be installed on undersea mining car 3, and expansion link and the support 11 of lift telescopic cylinder are hinged, and this lift telescopic cylinder can adopt telescopic oil cylinder.
In the present embodiment, pipeline comprises and gathers the collection pipe 6 that is connected of cover 22 and be connected to the delivery hose 7 collected between pipe 6 and pump 21, the rectangular in cross-section of collection pipe 6, and the section area of collection pipe 6 reduces gradually Zi gathering the direction of cover 22 to delivery hose 7, is beneficial to the collection of broken cobalt bearing crust.Simultaneously, collection pipe 6 is connected to and gathers in the front end side wall sidewall of direct of travel side (the undersea mining car 3 work) of cover 22, the lower surface of collection pipe 6 is the arcwall face upwarped, arcwall face smoothly connects with the lower surface gathering cover 22, collection pipe 6 entrance width is greater than broken width when crushing roller 12 works, so that the particle under crushing roller 12 fragmentation gathers in time.Meanwhile, the arc upwarped on arcwall face and slide plate 23 of collection pipe 6 lower end is positioned on same arcwall face, to adapt to be about to broken ore bed surface.Such collection pipe 6 also can not cause interference to normal work, and adapts to the change of seabed mima type microrelief.
Seabed of the present invention cobalt bearing crust fragmentation gathers integrated apparatus while the cobalt bearing crust ore bed of crushing roller 12 broken seabed, cobalt bearing crust after fragmentation can be collected through collection pipe 6 and delivery hose 7 by pump 21 at once, the requirement of collecting instantaneously after reaching fragmentation, greatly can improve broken collecting efficiency, reduce cost of production.
Operating principle and the process of the seabed cobalt bearing crust fragmentation collection integrated apparatus of the present embodiment are as follows:
When starting the mining of cobalt bearing crust, undersea mining car 3 is parked in cobalt bearing crust exploitation original position, opens pump 21, then open motor, drive crushing roller 12 to rotate, the direction of rotation of crushing roller 12 as indicated by arrow b of figure.After crushing roller 12 and pump 21 work well, elevating mechanism 4 orders about support 11, motor, crushing roller 12, gathers the parts descending motions such as cover 22, bearing support.First the slide plate 23 gathering cover 22 lower end contacts with seabed cobalt bearing crust ore bed.After slide plate 23 contacts with seabed cobalt bearing crust, elevating mechanism 4 orders about the parts such as support 11, motor, crushing roller 12, bearing support and continues descending motion, because slide plate 23 contacts with cobalt bearing crust ore bed, slide in the chute of slide block on collection cover 22 on support 11, crushing roller 12 continues to drop to contact cobalt bearing crust ore bed, at this moment crushing roller 12 starts to cut broken cobalt bearing crust, cobalt bearing crust particle under broken, due to the water suction effect of pump 21, is discharged through collection pipe 6, delivery hose 7 and pump 21 successively.After the degree of depth of cutting cobalt bearing crust when crushing roller 12 reaches requirement, elevating mechanism 4 stops action, opens undersea mining car 3, and undersea mining car 3 is advanced along arrow A direction in Fig. 1.When mining vehicle moves ahead, slide plate 23 supports collection cover 22 and slides on cobalt bearing crust ore bed surface, and crushing roller 12 continues broken cobalt bearing crust ore bed, and the cobalt bearing crust particle simultaneously under fragmentation is collected by collection assembly 2.
The above is only the preferred embodiment of the present invention, and protection scope of the present invention is also not only confined to above-described embodiment.For those skilled in the art, do not departing from the improvement that obtains under the technology of the present invention concept thereof and conversion also should be considered as protection scope of the present invention.
