[0029] Please see Figs. 1-3 As shown in the figure, the utility model provides a drill soil throwing noise reduction device, which is arranged below the drill, comprises a cleaning assembly 100 and a fixing assembly 200, the top of the cleaning assembly 100 is formed with a cleaning end, the bottom of the cleaning assembly 100 is formed with a connecting end, the cleaning end is arranged towards the drill, so that the soil in the drill contacts the cleaning end to break the surface tension of the soil and realize soil cleaning during the up-down movement of the drill; and the fixing assembly 200 is arranged on the ground and fixedly connected with the connecting end to stabilize the cleaning assembly 100.
[0030] The utility model discloses a cleaning assembly 100 and the top of the cleaning assembly 100 has a cleaning end, so that it is arranged below the drill during use, the cleaning end contacts the soil remaining in the drill during the up-down movement of the drill, so that the cleaning end can break the surface tension of the mud block on the drill, the mud block falls off the drill to realize the purpose of soil cleaning, and the noise in the pile foundation construction process is greatly reduced because the frequent soil throwing, knocking of the drill and the soil throwing mode of collision of the drill with the ground are avoided and the cleaning end contacts the soft soil.
[0031] Meanwhile, the fixing assembly 200 can ensure the stability and stress intensity of the cleaning assembly 100 during the up-down movement of the drill, so that the actual use effect and use quality of the utility model device can be ensured, and the utility model has high practicability and good use effect.
[0032] It is easy to understand that the cleaning end of the cleaning assembly 100 cleans the soil by inserting into the soil of the drill and breaking the surface tension of the soil. Therefore, in some embodiments, the cleaning assembly 100 can adopt a rod-shaped structure or a columnar structure.
[0033] However, the drilling size of the drill limits the size of the cleaning assembly 100 adopting the rod-shaped structure or the columnar structure, that is, only a thin rod can be used; and at the same time, the cleaning assembly 100 bears the downward pressure during soil cleaning, so that higher requirements are put forward for the structural strength of the cleaning assembly 100 in order to avoid breakage.
[0034] Therefore, in the preferred embodiment, the cleaning assembly 100 adopts a conical structure, the radial dimension of the outer edge of the cleaning assembly 100 gradually increases from the cleaning end to the connecting end.
