Hard object digger with excellent functions

Abstract

The invention discloses a hard object digger with excellent functions. The hard object digger comprises a column handle, a selector, a core device and a sheath; a plurality of selection devices are mounted on the left side of the core device, and the column handle is mounted on the left sides of the multiple selection devices; a circuit is mounted on the left side of the column handle, and a starting button is mounted on the lower side of the column handle; a handle is mounted on the upper side of the core device, and handle rotating shafts are mounted on the lower side of the handle; a rotating column is mounted in the core device, and pressure relieving sheets are mounted on the lower side of the rotating column; the selector is mounted in the core device and connected with an air pump through a linkage rod; a digger body is mounted on the lower side of the sheath, and a rotating shaft is mounted on the surface of the digger body; and the selector is connected with the rotating shaftthrough a linkage belt, and a control key is mounted on the surface of the core device. An insurance device is additionally arranged to serve as a receptor of the core device, thus once the core device generates any undesirable phenomenon, work is immediately stopped, power-off treatment is conducted to protect the hard object digger, and thus the safety of the hard object digger is guaranteed.

Description

technical field [0001] The invention relates to the technical field of cement slotting, in particular to a hard object excavator with excellent functions. Background technique [0002] Hard object excavators used on the market are basically blank areas. So how to dig, dig holes and so on? Generally, a plan is first made for the shape, and then slowly hollowed out with tools. This method is too primitive and inefficient, so it affects the work. The second is to use a cutting machine, and then excavate, but the huge noise and dust will be generated during the work, which will make the staff bear a huge risk of getting sick due to work. Therefore be badly in need of a kind of good hard object excavator to improve this phenomenon. Contents of the invention [0003] The purpose of the present invention is to solve the shortcoming existing in the prior art, and propose a kind of function excellent excavator for hard objects. [0004] In order to achieve the above object, th...
