Because in the process of drilling and sampling, the drill bit 9 always rubs with a mineral deposit, the drill bit 9 heats, so the temperature of mineral aggregate drilled through the drill bit 9 is higher, at the moment, the guide pipe 201 is connected with external water circulation equipment, the external water circulation equipment is used for introducing cooling water into the left guide pipe 201, the left guide pipe 201 is used for inputting the cooling water into the heat dissipation cavity 1001 through the water pipe 202, the liquid level in the heat dissipation cavity 1001 rises along with the rising of the liquid level of the cooling water in the heat dissipation cavity 1001, then the cooling water in the heat dissipation cavity 1001 enters into the right guide pipe 201 through the water pipe 203, finally, the cooling water flows back into the water circulation equipment through the right guide pipe 201, the temperature of the circulating water is reduced, as shown in fig. 5, the mineral aggregate which is upwards conveyed by the auger 7 in the limit pipe 10 is reduced, the higher temperature of the mineral aggregate sample is effectively avoided, the oxidation caused by the contact with air or the deterioration of the mineral aggregate sample is accelerated during the export, and the analysis accuracy of mineral aggregate in the mineral deposit is affected.
As shown in fig. 6, after drilling is completed, the equipment is transferred to a designated equipment cleaning area, so that pollution to the surrounding environment caused by cleaned mineral aggregate is avoided, and cleaning of the equipment is mainly performed in two aspects, on one hand, mineral aggregate still remains on a drill bit 9 and is not cleaned in time, then when another mineral deposit is sampled, mineral aggregate remaining on the drill bit 9 can affect detection of mineral aggregate in different sampling areas, through an electric spray head 10102 arranged at the lower part of a conical sleeve 101, wherein after drilling is completed, as an opening of a water pipe 202 is close to the bottom of a heat dissipation cavity 1001, an opening of a water pipe 203 is close to the top of the heat dissipation cavity 1001, after an external water circulation device stops pumping water to the heat dissipation cavity 1001, cooling water still remains in the heat dissipation cavity 1001 and a water storage tank 10101, the electric spray head 10102 sprays water in the heat dissipation cavity 1001 and the water storage tank 10101 to the drill bit 9, so that the cooling water is sprayed from top to bottom of the drill bit 9, the residual mineral aggregate on the drill bit 9 is eluted, further, the cooling water is effectively prevented from residing in the heat dissipation cavity 1001 and the water storage tank 10101, the weight of the equipment is increased, and the equipment is prevented from being corroded, and the equipment is reduced, and the equipment is prevented from being corroded and corroded.
After the sampling is completed, as the excessive mineral aggregate is discharged from the gap between the spacing pipe 10 and the drill hole, the mineral aggregate is adhered to the outer wall of the spacing pipe 10, and the two C-shaped pipes 302 are communicated with the external water pump first, so when the top of the spacing pipe 10 is about to reach the partition 301, as shown in fig. 2, the C-shaped pipes 302 spray water through the corresponding spray guns 303 on the C-shaped pipes, and the spray nozzles 303 spray clean water towards the side wall of the spacing pipe 10, so that the side wall of the spacing pipe 10 is washed, and the situation that the spacing pipe 10 carries the mineral aggregate to the next sampling place and influences the next deposit sampling is avoided.
As shown in fig. 8, and considering that the position of the deposit is not always planar, by providing a plurality of taper bars 403 capable of automatically adjusting the length, the apparatus is horizontally fixed on the deposit by inserting the taper bars 403 into the deposit, so as to be convenient for completely collecting the mineral aggregate samples at each position of the deposit, avoiding the prior art that the sampling position needs to be flattened, thereby losing part of the mineral aggregate samples on the surface of the deposit, affecting mineral analysis on the deposit, and then providing a plurality of elastic stabilizer bars 402 for buffering the shake of the apparatus in the horizontal direction generated during operation, and the cooperation of the bottom frame 401 and the taper bars 403, so that the housing 1 is separated from the ground of the deposit, and further protecting the housing 1 and the auger 7 when not in operation.
The above embodiments are provided to illustrate the technical concept and features of the present invention and are intended to enable those skilled in the art to understand the content of the present invention and implement the same, and are not intended to limit the scope of the present invention. All equivalent changes or modifications made in accordance with the spirit of the present invention should be construed to be included in the scope of the present invention.
