Finally, the heat is discharged through the upper part of the installation cylinder. And because the position where the air inlet groove is opened is on the lower surface of the installation cylinder, the outside air can strengthen the air exchange inside the storage pool during the flow process, further improving the cooling effect and facilitating subsequent reuse.

[0018] In the following description, many specific details are set forth in order to fully understand the present invention. However, the present invention can also be implemented in other ways different from those described herein. Therefore, the present invention is not limited by the limitations of the specific embodiments disclosed below.

[0019] As Figures 1-6 shown, an improved exploration drill with high stability includes a mobile vehicle 1. A drilling structure 2 is arranged on the top of the mobile vehicle 1. A mud pump 101 is arranged on the top of the mobile vehicle 1. The mud pump 101 is used to pump in mud for cooling during the drilling process of the drilling structure 2; An auxiliary mechanism 4, the auxiliary mechanism 4 includes a positioning component 41 and a filtering component 42. The positioning component 41 arranged on the surface of the drilling structure 2 is used for positioning and guiding the drill bit during the downward movement. The filtering component 42 is arranged on one side of the mobile vehicle 1, and the filtering component 42 is used for filtering the debris in the mud return.

[0020] As Figures 1-6 shown, the positioning component 41 includes a mounting block 4101. The cross-sectional shape of the mounting block 4101 is circular. A pressure regulating cavity 4105 is opened at the bottom of the mounting block 4101. The drill bit of the drilling structure 2 can pass through the inside of the mounting block 4101 and the pressure regulating cavity 4105.

[0021] The top of the mounting block 4101 is provided with evenly distributed grooves 4104. A threaded hole is opened on the inner bottom wall of the groove 4104. An adjusting block 4109 is detachably arranged inside the groove 4104. Evenly distributed limiting grooves 4110 are opened on the surface of the adjusting block 4109. The bottom of the adjusting block 4109 is fixedly connected with a positioning screw 4103. The lower end of the positioning screw 4103 penetrates out of the threaded hole and is threadedly connected with the inner wall of the threaded hole.

[0022] The inner wall of the pressure regulating chamber 4105 is provided with uniformly distributed connecting chambers 4102, the connecting chambers 4102 correspond to the grooves 4104, a pressure receiving plate 4107 is slidably connected to the inner wall of the connecting chamber 4102, a limiting rod 4108 is fixedly connected to one side of the pressure receiving plate 4107, a spring 4106 is fixedly connected to the surface of the pressure receiving plate 4107, and the other end of the spring 4106 is fixedly connected to the inner wall of the connecting chamber 4102.

[0023] One end of the limiting rod 4108 penetrates out of the connecting chamber 4102 and extends into the adjacent limiting groove 4110.

[0024] By placing the mounting block 4101 on the ground to be explored and rotating the adjusting block 4109, the positioning screw 4103 can be driven to pass through the threaded hole and insert into the ground to limit the position of the mounting block 4101. During the exploration drilling process, the cooled mud can be injected into the pressure regulating chamber 4105. The mud entering the pressure regulating chamber 4105 can be injected into the connecting chamber 4102 and push the pressure receiving plate 4107 away from the drill bit. At the same time, during the movement of the pressure receiving plate 4107, the spring 4106 can be compressed and the limiting rod 4108 can be driven to pass through the connecting chamber 4102 and insert into the adjacent limiting groove 4110 to limit the position of the adjusting block 4109, thus completing the limitation of the position of the adjusting block 4109. It can effectively prevent the reverse loosening of the positioning screw 4103 caused by vibration during the drilling process, ensure the limitation of the position of the mounting block 4101, and at the same time, the overflow of the discharged mud can be reduced through the pressure regulating chamber 4105, and the discharged mud can be well collected.

[0025] As Figures 1-6 shown, the filtering assembly 42 includes a storage tank 4202 arranged on one side of the mobile vehicle 1. The inside of the storage tank 4202 is filled with mud for cooling. One side of the storage tank 4202 is communicated with an inlet pipe 4201, and the other end of the inlet pipe 4201 is communicated with the liquid inlet end of the mud pump 101. The other side of the storage tank 4202 is provided with a discharge pipe 4204, and the other end of the discharge pipe 4204 is communicated with the connecting chamber 4102.

[0026] A fixed shell 4210 is fixedly connected to the inside of the storage tank 4202. The top of the fixed shell 4210 is provided with a mounting plate 4211 threadedly connected to the inner wall of the fixed shell 4210. The bottom of the mounting plate 4211 is fixedly connected with a filter screen 4209 located inside the fixed shell 4210. One end of the discharge pipe 4204 is communicated with the fixed shell 4210.

[0027] The inner wall of the storage tank 4202 is fixedly connected with an installation cylinder 4203. The surface of the installation cylinder 4203 is provided with a through groove that penetrates up and down. The inner wall of the through groove is fixedly connected with a stop block 4206. The inner wall of the through groove is fixedly connected with a fan 4205 located above the stop block 4206. A cooling area is formed between the fan 4205 and the stop block 4206. The surface of the installation cylinder 4203 is provided with evenly distributed air inlet grooves 4208. The surface of the installation cylinder 4203 is provided with a connecting pipe 4212 that communicates with the cooling area. The other end of the connecting pipe 4212 communicates with a fixed shell 4210.

[0028] The reversed mud can be introduced into the interior of the fixed shell 4210 under the action of the discharge pipe 4204. During this process, the debris generated during the drilling process can be filtered and intercepted by the filter screen 4209, ensuring the fluidity of the mud and preventing the debris from reusing with the mud and causing wear to the drill bit. At the same time, the filtered mud can be introduced into the cooling area through the connecting pipe 4212 and fall above the stop block 4206 under the action of gravity. Then, it can be discharged into the interior of the storage tank 4202 through the through hole 4207 for storage and reuse. At the same time, by starting the fan 4205, the outside air can be introduced into the cooling area through the air inlet groove 4208 and the through hole 4207 to act on the cooled mud. Finally, the heat is discharged through the upper part of the installation cylinder 4203. And because the air inlet groove 4208 is opened on the lower surface of the installation cylinder 4203, the outside air can strengthen the air exchange inside the storage tank 4202 during the flow process, further improving the cooling effect and facilitating subsequent reuse.

[0029] Working principle: Place the installation block 4101 on the ground to be explored. By rotating the adjustment block 4109, the positioning screw 4103 can be driven to pass through the threaded hole and insert into the ground to limit the position of the installation block 4101. Then, align the drill bit of the drilling structure 2 with the inside of the installation block 4101 through the moving vehicle 1 and lower it to carry out exploration operations. During the exploration drilling process, the cooled mud can be injected into the pressure regulating chamber 4105. The mud entering the pressure regulating chamber 4105 can be injected into the connection chamber 4102 and push the pressure receiving plate 4107 away from the drill bit. At the same time, during the movement of the pressure receiving plate 4107, the spring 4106 can be compressed and the limiting rod 4108 can be driven to pass through the connection chamber 4102 and insert into the adjacent limiting groove 4110 to limit the position of the adjustment block 4109, thus completing the limitation of the position of the adjustment block 4109. This can effectively prevent the reverse loosening of the positioning screw 4103 caused by vibration during the drilling process, ensure the limitation of the position of the installation block 4101, and at the same time, the overflow of the discharged mud can be reduced through the pressure regulating chamber 4105, and the discharged mud can be well collected. The collected mud can be introduced into the fixed housing 4210 under the action of the discharge pipe 4204. During this process, the debris generated during the drilling process can be filtered and intercepted by the filter screen 4209 to ensure the fluidity of the mud and avoid the wear of the drill bit caused by the reuse of the debris with the mud. At the same time, the filtered mud can be introduced into the cooling area through the connecting pipe 4212 and fall above the baffle 4206 under the action of gravity. Then, it can be discharged into the storage tank 4202 through the through hole 4207 for storage and reuse. At the same time, by starting the fan 4205, the outside air can be introduced into the cooling area through the air inlet groove 4208 and the through hole 4207 to act on the cooled mud, and finally the heat is discharged through the upper part of the installation cylinder 4203. And because the air inlet groove 4208 is opened on the lower surface of the installation cylinder 4203, the outside air can strengthen the air exchange inside the storage tank 4202 during the flowing process, further improving the cooling effect and facilitating subsequent reuse.
