Detailed implementation manners

[0023] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0024] Please refer to Figures 1-4 , a pit-digging device for infrastructure construction, including a support component for supporting the drilling, above which there is a drilling component for lifting and drilling with a spiral drill, and further including an adjusting component installed between the support component and the drilling component for adjusting the drilling angle by double-axis rotation.

[0025] In this embodiment: The support component includes a frame 101. Four rollers 104 are evenly arranged at the four corners below the frame 101. Four fixed rods 102 are evenly arranged on the frame 101. A knob 103 is arranged at the top of the fixed rod 102. The fixed rod 102 is threadedly connected to the frame 101. With the support of the rollers 104, the device is moved to the pit-digging position through the frame 101. Subsequently, the four fixed rods 102 are rotated by the knob 103 to make them contact the ground downward, fixing the position of the frame 101 and ensuring the stability of the frame 101 during drilling;

[0026] In this embodiment: The drilling component includes a support frame 201. An electric push rod 202 is installed on the support frame 201. An lifting frame 204 is arranged at the bottom of the electric push rod 202. Two limit rods 203 are symmetrically arranged front and back on the lifting frame 204. A drilling motor 205 is arranged between the two limit rods 203. A drill bit 206 is installed below the drilling motor 205. The limit rod 203 is cylindrical in shape and is slidably connected to the support frame 201. The drilling motor 205 drives the drill bit 206 to rotate. Subsequently, the support frame 201 supports the electric push rod 202 to extend, driving the drill bit 206 to move downward along the limit rod 203 through the lifting frame 204 for drilling;

[0027] In this embodiment: The adjusting assembly includes two symmetrically arranged support plates 301 on both sides. An adjusting frame 302 is rotatably installed between the two support plates 301. A first worm gear 303 is installed on one side of the adjusting frame 302. A first worm 304 is engaged with the lower surface of the first worm gear 303. A first adjusting motor 305 is installed in front of the first worm 304. A second worm gear 306 is arranged in front of the adjusting frame 302. A second worm 307 is engaged with one side of the second worm gear 306. A second adjusting motor 308 is installed above the second worm 307. The support frame 201 is rotatably connected to the adjusting frame 302. The second worm gear 306 is connected to the support frame 201 by a flat key. When the drilling angle needs to be adjusted, the adjusting frame 302 supports the second adjusting motor 308 to drive the second worm 307 to engage with the second worm gear 306 and rotate, so that the support frame 201 drives the drill bit 206 to swing to both sides. At the same time, the support plate 301 supports the first adjusting motor 305 to drive the first worm 304 to engage with the first worm gear 303 and rotate, so that the adjusting frame 302 drives the drill bit 206 to swing back and forth through the support frame 201 to adjust the drilling angle. Through the above-mentioned dual-axis adjustment setting, the adjustment of the drilling angle is not limited to one plane, expanding the adjustment range.

[0028] Working principle: Supported by the rollers 104, the device is moved to the digging position through the frame 101. Subsequently, the four fixing rods 102 are rotated by the knob 103 to make them contact the ground downward to fix the position of the frame 101 and ensure the stability of the frame 101 during drilling; when the drilling angle needs to be adjusted, the adjusting frame 302 supports the second adjusting motor 308 to drive the second worm 307 to engage with the second worm gear 306 and rotate, so that the support frame 201 drives the drill bit 206 to swing to both sides. At the same time, the support plate 301 supports the first adjusting motor 305 to drive the first worm 304 to engage with the first worm gear 303 and rotate, so that the adjusting frame 302 drives the drill bit 206 to swing back and forth through the support frame 201 to adjust the drilling angle. Through the above-mentioned dual-axis adjustment setting, the adjustment of the drilling angle is not limited to one plane, expanding the adjustment range; after the adjustment is completed, the drilling motor 205 is driven to rotate the drill bit 206. Subsequently, the support frame 201 supports the electric push rod 202 to extend, and drives the drill bit 206 to move downward along the limiting rod 203 through the lifting frame 204 to perform drilling.

[0029] Although the embodiments of the present invention have been shown and described, for those of ordinary skill in the art, it can be understood that various changes, modifications, substitutions and variations can be made to these embodiments without departing from the principle and spirit of the present invention. The scope of the present invention is defined by the appended claims and their equivalents.
