When the data acquisition device 2 is inserted into a coal seam according to the working principle, the electric push rod 5 in the cavity 4 is started, the output rod 6 of the electric push rod 5 is enabled to move with the connecting plate 8 and the crushing rod 9, at the moment, the connecting plate 8 and the crushing rod 9 can be positioned in front of the data acquisition device 2, stones in the coal seam in front of the data acquisition device 2 are crushed by the aid of the crushing rod 9 and guided by the aid of the arc-shaped connecting plate 8, hard sundries in front of the data acquisition device 2 are further reduced, and meanwhile the crushing rod 9 can be inserted into the coal seam, so that the auxiliary positioning function is achieved. Thereby make things convenient for data collection system 2 to insert in the coal seam and fix, reduce the damage of the intraductal hard object of coal to data collection system 2 end simultaneously, make things convenient for data collection system 2 to use for a long time and data acquisition formation of image. The information acquired by the data acquisition device 2 can be transmitted into the host 1 of the channel wave seismic prospecting device, so that the host 1 can conveniently draw data imaging, and accordingly workers can observe coal seam information in real time. Through installing the rotor 11, and then play supplementary removal and reduce the friction between connecting plate 8 and the coal seam, simultaneously scraper blade 12 on rotor 11 can rotate along with it, and then play broken and supplementary effect of advancing. When the impurity of coal seam falls into rectangular channel 10, curved scraper blade 12 can impurity rotate and take out rectangular channel 10 in, and scraper blade 12 still can constantly strike iron sheet 13 in the rectangular channel 10, and then produces the vibration to play mediation rectangular channel 10, prevent that rectangular channel 10 from blockking up and causing the unable pivoted condition of rotor 11 to take place. Through installing bellows 14 in logical inslot 7, utilize bellows 14 to reduce dust and impurity entering cavity 4, when output rod 6 carries bellows 14 to remove, bellows 14 can shrink and then extrude elastic ball 15 in the clearance, inside gas can blow off through the shrinkage cavity after elastic ball 15 is extrudeed, and then blow off the cinder on bellows 14 surface to prevent that cinder from blockking the shrink of bellows 14, play the effect of automatically cleaning bellows 14, make things convenient for bellows 14's long-time use. The elastic piece 16 and the elastic block 18 are arranged in the gap of the corrugated pipe 14, so that coal cinder can be sprung up by the elastic piece 16 and the elastic block 18 after falling into the gap, and then the falling coal cinder is ejected, so that the condition that the elastic ball 15 is difficult to blow away after larger coal cinder falls into the gap of the corrugated pipe 14 is avoided.
When the output rod 6 of the electric push rod 5 is reset to recovery, the fixing rod 20 and the pressing plate 21 are driven to move towards the direction of the elastic block 18, so that the pressing plate 21 extrudes the elastic block 18, water preloaded in the elastic block 18 is sprayed out through the connecting pipe 19, the top end of the connecting pipe 19 is further opened to open the end cover 22, water in the connecting pipe 19 can be sprayed out smoothly, at the moment, the arc-shaped guide plate 23 on the end cover 22 also plays a role in guiding water flow, so that water flows to the end of the data collector 2 to spray out, a better cleaning and flushing effect is achieved, coal cinder on the data collector 2 is reduced, and the recovery and the utilization of the data collector 2 are facilitated. Through installation curb plate 25, when clamp plate 21 is when extrudeing elastic piece 18, curb plate 25 can play fine restriction its effect of deformation, and then make things convenient for curved clamp plate 21 better extrusion elastic piece 18 for water in the elastic piece 18 can be highly efficient blowout, and simultaneously through-hole 24 on the clamp plate 21 can reserve the space of deformation for elastic piece 18, avoids elastic piece 18 to be excessively extruded and does not have deformation space to lead to the circumstances of damage to take place. Meanwhile, the balls 26 on the side plates 25 can assist in rotating and extruding the elastic block 18, so that the efficiency of extruding water from the elastic block 18 is improved. Through the top at the storage frame 3 installation guard shield 27, cover the port of connecting pipe 19 with guard shield 27 to avoid cinder and impurity to drop and smash the connecting pipe 19 that exposes outside cavity 4, and semicircular guard shield 27 can play the effect to both sides direction to debris, and the debris that baffle 28 blockked on the guard shield 27 falls to bellows 14 department simultaneously, plays the effect of protection bellows 14 simultaneously.
