Detailed Description

The present invention will be described in further detail with reference to the drawings and specific embodiments of the specification, wherein components or systems not specifically described in the present embodiment are all in the prior art, and the left side of fig. 1 is taken as the left side, the right side as the right side, the upper side is taken as the upper side, and the lower side is taken as the lower side.

Example 1

As shown in fig. 1-4, the present embodiment is a pit excavator for a construction site, which includes a drill 6 and a driving motor 5, wherein the drill 6 includes a spiral blade 62 and a spindle 61, the spindle 61 is connected to the driving motor 5, the driving motor 5 drives the spindle 61 to rotate, and further drives the spiral blade 62 to rotate synchronously, and the pit excavator is characterized in that: the device also comprises a support column and a cross rod 3, wherein the support column consists of a base 1 and a vertical rod 2, and the vertical rod 2 is erected on the ground through the base 1; the cross bar 3 is used to connect the drill bit 6 and the support column, so that the drill bit 6 is upright and freely displaced in the vertical direction, while not restricting the free rotation of the drill bit 6 about its main axis 61.

The base 1 in the embodiment is in a truncated cone shape, and is suitable for a scene with a relatively flat ground.

Every two horizontal poles 3 form a set of, and every group horizontal pole 3 independently accomplishes the fixed action to drill bit 6, and the one end of horizontal pole 3 has circular through-hole, and on pole setting 2 was located through this through-hole cover to horizontal pole 3, make horizontal pole 3 can follow the length direction of pole setting 2 and freely slide from top to bottom, and the other end of horizontal pole 3 is semicircular structure, and the one end that will have semicircular structure with horizontal pole 3 in a set of mutually supports and has formed complete round hole, and main shaft 61 on the drill bit 6 is arranged in the round hole of this formation.

The main shaft 61 is provided with a stop block 63, the cross rod 3 is arranged above the stop block 63, and the size of the stop block 63 is larger than the size of a complete round hole formed by the semicircular structure, so that the stop block 63 bears the gravity transmitted by the cross rod 3.
