Abstract
The utility model discloses a device used for the coal preparing plant to pick the coal sample in the blanking chute of the centrifugal machine. A sampling connection sealed blocking plate and a material receiving groove connected with the sampling connection sealed blocking plate are installed on a blanking chute, when the sampling is not performed, the sealed blocking plate closes up to the wall of blanking chute, to prevent the coal dust in the chute from being outward diffused and to protect the environment; when the sampling is performed, the driving lever is turned to ensure that the sealed blocking plate is departed from the wall of the blanking chute, simultaneously, the material receiving groove is upturned, at the moment, the material can flow to the outside of the blanking chute along with the material receiving groove, and the purpose that the sampling and the reposition after the sampling is finished can be realized. The movement of the driving lever is driven by dint of an oil cylinder, the oil cylinder is controlled by a time relay and a controlling valve, and the automatic sampling can be realized.
Description
Technical field
The utility model relates to a kind of mining equiment, is specifically related to the device of the sampling in the hydro-extractor chute of coal preparation plant's use.
Background technology
At present, the method for taking coal sample in the hydro-extractor chute that much coal preparation plants use generally is to make a sampling window in chute, manually gets material from window when needing sampling.Because in the hydro-extractor chute is malleation, during sampling, causes coal dust to spread from window, serious environment pollution, infringement operator health.
Summary of the invention
The utility model provides a kind of interlocking sampling thief, and it is to open a rectangle dumping pit on the chute implementing, and sealing baffle is installed in the upper end in hole, and the groove that connects material is installed in the lower end, connects with rope between the two.The oil cylinder that is installed on the blanking chute is connected with sealing baffle by driving lever, and oil cylinder is by petroleum pipeline and operation valve, and oil pump connects, and operation valve connects with the time relay by lead.
Of the present utility model with following technical scheme realization: a kind of interlocking sampling thief, comprise blanking chute, sealing baffle, the groove that connects material, oil cylinder, oil pump, operation valve, the time relay, it is characterized in that: make the rectangle dumping pit on the described blanking slide carriage, the periphery of dumping pit is made ring-type rectangle bulge loop; The upper end of described sealing baffle and the welding of sleeve outer circle cylinder, axle sleeve is sleeved on by the axle sliding fit in the hole of support, and two pack supports are welded on the outer end of blanking chute; One end of driving lever and the welding of the external cylindrical surface of axle sleeve, the other end of driving lever and the piston rod end of oil cylinder are hinged; Described oil cylinder and support are hinged, and support is fixed on the outer face of blanking chute; Two pack supports are separately fixed on the groove lower surface that connects material, and two supports are separately fixed at the inboard of the dumping pit on the blanking chute, and support and support are by the axle hinge joint; Described sealing baffle connects by rope between the groove with connecting material; Described oil cylinder connects with operation valve, oil pump by petroleum pipeline; Described operation valve connects with the time relay by lead.
Angle γ between described driving lever and the sealing baffle 〉=90 degree.
The utility model has the advantages that: the sampling interval time-program(me) is input to the time relay, oil cylinder promotes driving lever automatically and prolongs axle rotation during sampling, the driving sealing baffle rotates to an angle and the blanking chute breaks away from, spurring the groove that connects material by rope simultaneously rotates up, got material and just from dumping pit, flow to blanking chute outside, realized sampling along the groove that connects material.The sampling back oil cylinder that finishes drives driving lever automatically sealing baffle is resetted, and the groove that connects material is got back to initial position automatically by deadweight, realizes the sampling robotization, prevents that coal dust from spreading.
Description of drawings
Below in conjunction with drawings and Examples the utility model is described in further detail.
Fig. 1 is the utility model structural representation;
Fig. 2 is the right view of Fig. 1.
Among the figure: 1, driving lever, 2, axle, 2-1, cover, 3, sealing baffle, 4, axle, 5, the groove that connects material, 6, the blanking chute, 6-1, dumping pit, 6-2, rectangle bulge loop, 7, support, 8, support, 9, support, 10, rope, 11, oil cylinder, 12, petroleum pipeline, 13, operation valve, 14, oil pump, 15, the time relay, 16, lead, 17, axle sleeve, 18, support.
Embodiment
As shown in Figure 1 and Figure 2, a kind of interlocking sampling thief, comprise blanking chute 6, sealing baffle 3, the groove 5 that connects material, oil cylinder 11, oil pump 14, operation valve 13, the time relay 15, it is characterized in that: make rectangle dumping pit 6-1 on the described blanking slide carriage 6, the periphery of dumping pit 6-1 is made ring-type rectangle bulge loop 6-2; The upper end of described sealing baffle 3 and the welding of axle sleeve 17 external cylindrical surfaces, axle sleeve 17 is sleeved in the hole of support 9 by axle 2 sliding fits, and two pack supports 9 are welded on the outer end of blanking chute 6; One end of driving lever 1 and the welding of the external cylindrical surface of axle sleeve 17, the piston rod end of the other end of driving lever 1 and oil cylinder 11 is hinged; Described oil cylinder 11 is hinged with support 18, and support 18 is fixed on the outer face of blanking chute 6; Two pack supports 8 are separately fixed on groove 5 lower surfaces that connect material, and two supports 7 are separately fixed at the inboard of the dumping pit 6-1 on the blanking chute 6, and support 8 links by axle 4 with support 7; Described sealing baffle 3 connects by rope 10 between the groove 5 with connecting material; Described oil cylinder 11 connects with operation valve 13, oil pump 14 by petroleum pipeline 12; Described operation valve connects with the time relay 15 by lead.
Angle γ between driving lever 1 and the sealing baffle 3 〉=90 degree.
As shown in Figure 1 and Figure 2, the axle sleeve 17 that sealing baffle 3 upper ends are fixed is hinged with the support 9 that is fixed on the blanking chute 6 by axle 2, and sealing baffle 3 is not close to the blanking chute walls when not sampling at ordinary times, prevents that coal dust is to external diffusion.
When needing sampling, the time relay 15 automatic drive control valves 13 are to oil cylinder 11 fuel feeding, oil cylinder 11 pulling driving levers 1 rotate up, because driving lever 1 is welded on the axle sleeve 17 simultaneously with sealing baffle, sealing baffle 3 just rotated thereupon and left the blanking chute walls this moment, spur the upwards upset of groove 5 that connects material by rope 10 simultaneously, the material thing in the blanking chute 6 will flow to blanking chute 6 outsides along the groove 5 that connects material at this moment, realizes sampling.(position of representing as dotted line among Fig. 2).After sampling was finished, the time relay 15 drove driving lever 1 return by 11 work of operation valve 13 control oil cylinders, and sealing baffle 2 is pressed close to blanking chute walls 6 and blocked dumping pit 6-1, prevents that effectively coal dust is to external diffusion.The groove 5 of connecting material this moment automatically resets by deadweight.
