Detailed Description
The technical solution of the present patent will be described in further detail with reference to the following embodiments.
Referring to fig. 1-2, a tree planting hole digger with a drill pipe blade capable of being spirally extended comprises a drill pipe base 1 connected with the hole digger, wherein a drill pipe 2 is arranged on the drill pipe base 1, a drill bit 3 is arranged at one end, far away from the drill pipe base 1, of the drill pipe 2, a spiral blade 4 is arranged on the drill pipe 2, an extension blade 5 is arranged on the spiral blade 4, and the extension blade 5 is in a spiral arc shape; a plurality of rows of reserved threaded holes 6 are formed in the spiral blade 4, and butt-joint threaded holes 7 which are matched with the reserved threaded holes 6 in each row are formed in the lengthened blade 5; the lengthening blade 5 is connected with the spiral blade 4 through the matching of a reserved threaded hole 6, a butt-joint threaded hole 7, a screw and a nut, and the diameter of the rotary digging tree hole is adjusted. When the tree planting machine is used, the machine is simply lifted, the screws are loosened and detached, the required lengthening blades 5 are replaced, the structure is simple, the drill rods 2 of different specifications can be saved, the problem of the diameter of the tree pit excavation can be solved by only relying on a plurality of screws and nuts, the cost is relatively low, the operation is simple and convenient, and the tree planting efficiency is high.
The upper end of the drill rod base 1 is provided with a handle 8, so that the drill rod 2 can be conveniently lifted.
In addition, the size and the spacing of the butt joint threaded holes 7 are the same as those of the reserved threaded holes 6.
