The slideway support 1008 is sleeved outside the slideway 1007 and can move up and down along the slideway 1007. Bolt holes are formed above the slide 1007 and in the upper slide support 1008. When the screw feeder 10 takes only the material, the fixing pin is inserted, and the whole screw is fixed to the slide 1007 so as not to slide up and down. After the fixing pin is pulled out, the screw device sinks at the bottom of the trolley under the action of self weight and can slide up and down along with the height change of the material layer and the lifting of the trolley, so that the bin cleaning is realized. The pull rod system is formed by connecting an upper pull rod 1009, a lower pull rod 1012 and a connecting plate 1011 through a pull rod pin 1016. When two fixing pins 1015 are inserted, the connecting plate 1011 and the lower rod 1012 are fixed and cannot rotate relatively, and the spiral is kept horizontal. When the fixing pin is pulled down, the lower pull rod 1012 of the connecting plate 1011 can rotate relatively, and the material taking screw 1005 rotates at the moment to adapt to the shape of a material pile, so that floating material taking is realized. As shown in fig. 2, the left side and the front and rear sides of the scraper groove 202 are open structures, the right side is closed, and the outer surface of the right side is provided with a plowshare 205. When the trolley moves towards the right side, the materials enter the scraper groove 202 from the left side and the front and back sides of the scraper groove 202, and the spiral feeding device 10 can ensure the continuity of material flow. When the trolley moves to the left, the plow 205 can split the material pile on the right to guide the material to move to both sides, enter the spiral feeding device 10 and enter the scraper groove 202 from both sides of the scraper groove 202. Therefore, the vertical embedded scraper reclaiming system 2 can realize back-and-forth reciprocating continuous reclaiming under the coordination of the spiral feeding device 10 and the plowshare 205.

The vertical lifting system driving chain wheel, the connecting plate and the scraping plate are of an easily-detachable combined structure, parts made of different materials and different processes can be replaced according to test requirements, and the working reliability and the expected service life of the vertical lifting system driving chain wheel, the connecting plate and the scraping plate are verified through test simulation.

When the test is carried out, the specific steps are as follows:

the first step is as follows: materials to be tested are put into the carriage 1301 through the vehicle door 1302 by the material changing truck 7, and reach a certain material bed height.

The second step is that: depending on the material properties and the production rate requirements, the appropriate flights 204, large chains 203 and sprockets 2015 are selected and all speed parameters are determined.

The third step: the belt conveyor driving mechanisms 405 of the first telescopic cloth belt conveyor 4 and the second telescopic cloth belt conveyor 6 are started, and the turning plate 502 of the bifurcated chute 5 is confirmed to align the corresponding cloth belt conveyors.

The fourth step: the vertical buried scraper blade material taking system 2 is started, then the spiral feeding device 10 is started, then the trolley traction mechanism 11 is started, finally the telescopic driving mechanisms 404 of the first telescopic distribution belt conveyor 4 and the second telescopic distribution belt conveyor 6 are started, and the dust removal system 8 is started.

The fifth step: the material enters the scraper trough 202 through the screw feeder 10, and is lifted by means of the chain and the scraper. The lifted materials enter the forked chute 5 through the discharge chute 208 and fall into the corresponding distribution belt conveyor. Under the cooperation of the telescopic mechanism of the distribution belt conveyor, return materials uniformly fall into a carriage 1301 of the trolley through the head funnel 412 to complete distribution, and the test can be carried out circularly.

And a sixth step: the working state of the screw feeder 10 can be adjusted according to the actual requirements. In the material taking process, the bolt 1010 can be detached to enable the spiral to tilt towards two sides so as to adapt to the shape of the material pile. In the clearing stage, the fixing pin 1015 can be detached, so that the screw is placed at the bottom of the carriage 1301 under the action of self weight and floats along with the lifting of the carriage 1301, and the clearing effect is ensured.

The seventh step: a tester can observe the forming condition of the material loading pile of the scraper 204 through the lifting stage observation window 209 so as to judge whether the shape of the scraper 204, the chain pitch and the chain running speed are proper or not; observing the loosening and collapsing condition of the material pile through the observation window 210 in the discharging stage to judge whether the geometric dimension of the discharging slot 208 is reasonable or not; the driving torque of the sprocket can be detected in real time by the first torque sensor 2013 in the first driving mechanism 201 to obtain the real traction force of the chain. The second torque sensor 1103 in the trolley traction mechanism 11 can detect the motor torque in real time to obtain the real tension of the trolley traction steel wire rope 12, and deduce the running resistance of the trolley, i.e. the real resistance of the vertical embedded scraper system of the bridge type embedded scraper ship unloader in the process of pushing and taking materials. The real-time boost productivity of the vertical embedded scraper reclaimer system 2 can be measured by a belt scale 414 on the distribution belt conveyor.

Eighth step: when the test is stopped, all mechanisms are stopped one by one in the reverse direction of the starting sequence.

The ninth step: when a change of material is required, the change of material truck 7 is stopped at a fixed position and both cloth conveyors run to the extreme right, so that the head funnel 412 is aligned with the change of material truck 7. The materials in the carriage 1301 are lifted by the vertical buried scraper taking system 2, enter the discharge chute 208, enter the distribution belt conveyor through the branched chute 5, pass through the head hopper 412 and the material truck 7 until the materials in the carriage 1301 are completely emptied, and then stop.
