[0035] Specifically, by setting the first heat sink 6, during the process of filtering the drilling fluid, the first heat sink 6 is utilized to contact with the outside air to cool the drilling fluid in the fixed tube 2, thereby reducing the time consumed for cooling the drilling fluid and improving work efficiency. By setting the rotating disk 7, the support rod 8 can be driven to rotate, thereby driving the stirring rod 10 to rotate, stirring the drilling fluid, enhancing convection, and thereby improving the heat dissipation effect, so that the engineering geological drilling auxiliary equipment has the effect of improving the cooling efficiency of the drilling fluid.

The output end of the motor 12 passes through the lower surface of the cover plate 11 and is fixedly connected to the rotating disk 7. The rotating disk 7 is driven to rotate by the output end of the motor 12, and then the support rod 8 is driven to rotate, and then the stirring rod 10 is driven to rotate to stir the drilling fluid, so that the fixed particles move and reduce the clogging of the filter screen 4. The upper surface of the cover plate 11 is fixedly connected to a liquid inlet pipe 23 connected to the fixed cylinder 2.

[0037] A guide hopper 13 is formed on the upper surface of the base 1 at a position corresponding to the fixed cylinder 2, and a drainage pipe 14 is fixedly connected to the bottom of the guide hopper 13. The base 1 is hollow, and an end cover 15 is fixedly connected to the end face of the base 1. The guide hopper 13 is provided to facilitate the flow of the drilling fluid after filtration, and the drainage pipe 14 is provided to discharge the drilling fluid for recycling.

[0038] The inner cavity of the base 1 is provided with thermal conductive silicone grease, and a plurality of second heat sinks 16 are fixedly connected to the upper surface of the base 1.

Two semicircular collecting boxes 904 are arranged in the inner groove 902. The opening of the collecting box 904 corresponds to the docking port 903. By setting the docking port 903, when the docking port 903 corresponds to the slag discharge port 18, impurities in the fixed cylinder 2 can be discharged and fall into the collecting box 904. Under normal circumstances, the solid part of the sliding seat 901 corresponds to the slag discharge port 18, and the slag discharge port 18 is blocked.

[0044] Working principle: When the engineering geological drilling auxiliary equipment is used, the user first connects the drilling fluid recovery pipe of the drilling equipment with the liquid inlet pipe 23, and the liquid inlet pipe 23 transports the drilling fluid containing impurities into the fixed cylinder 2. The drilling fluid containing impurities is filtered by the filter screen 4 and then enters the discharge pipe 14 through the guide hopper 13, and the drilling fluid is discharged for recycling. In this process, the first heat sink 6 is used to contact with the outside air to cool the drilling fluid in the fixed cylinder 2, thereby reducing the time consumed for cooling the drilling fluid and improving work efficiency. The heat of the drilling fluid in the discharge pipe 14 is transferred to the second heat sink 16 by thermal conductive silicone grease, and the second heat sink 16 transfers the heat to the air to cool the drilling fluid. At the same time, the motor 12 is started, and the output end of the motor 12 drives the rotating disk 7 to rotate, the rotating disk 7 drives the support rod 8 to rotate, and the support rod 8 drives the stirring rod 10 to rotate, so as to stir the drilling fluid, enhance convection, and thereby improve the heat dissipation. The effect of heat, on the other hand, the stirring rod 10 rotates to stir the drilling fluid, so that the fixed particles move, reducing their clogging of the filter screen 4, and at the same time, the support rod 8 drives the scraper 17 to rotate to scrape off the impurities attached to the surface of the filter screen 4, further reducing the clogging of the filter screen 4; when it is necessary to clean the impurities on the fixed plate 3, start the electric cylinder 24, and the output end of the electric cylinder 24 drives the collecting part 9 to move downward until the docking port 903 is directly opposite to the slag discharge port 18, and then start the motor 12, and the output end of the motor 12 drives the rotating disk 7 to rotate, and the rotating disk 7 drives the support rod 8 to rotate, and the support rod 8 drives the pushing rod 19 to rotate, and the pushing rod 19 rotates to push the impurities intercepted by the filter screen 4 and falling on the fixed plate 3 in the direction away from the filter screen 4, until they move to the slag discharge port 18 and are discharged and fall into the collecting box 904, which is convenient for centralized cleaning, so that the engineering geological drilling auxiliary equipment has the effect of improving the cooling efficiency of the drilling fluid.
