According to a first aspect of the present disclosure, there is provided a desert boring device 1 for a crawler 21.

Because the in-process of drilling can produce the vibration, damping mechanism 15's setting can play certain speed reduction cushioning effect to make drilling mechanism 14 can be fast accurately drilled out the hole site of planting the sapling. In addition, because damping mechanism 15 and drilling mechanism 14 are connected through mortise and tenon structure (the cooperation structure of joint spare 16 and linking piece 12 promptly), consequently, even also can resume fast because of the displacement has appeared in the vibration, reduced the rigidity of tearing to fixing base 11 and pulled, avoid causing destructive damage.

In the present application, the universal transmission mechanism 13 is a mechanism for transmitting power by two shafts whose relative positions are constantly changed during operation, and functions to connect the transmission output shaft and the final drive input shaft which are not on the same straight line, and ensure that power can be reliably transmitted even when the included angle and distance between the two shafts are constantly changed. By the design, the remote power transmission can be realized, the load of the fixing seat 11 can be reduced, and meanwhile, the drilling mechanism 14 can drill stably and reliably, so that the desert drilling device 1 is better adapted to the desert environment.

Thus, the size of the portion of the drilling apparatus contacting the desert area is gradually changed, so that the second helical band 147 can gradually expand the hole and discharge the sand after the cutting blade 146 is inserted into the ground, and the first helical band 143 can gradually advance and further expand the hole with the push of the propelling member 144, thereby improving the discharge efficiency of the sand and further enabling the drilling apparatus to quickly and effectively expand the hole in the desert area.
