Description

Earth rammer of excavator

Technical Field

The utility model relates to an excavator earthwork rammer belongs to excavator accessory field.

Background

When foundation earthwork backfilling operation is carried out, the tamping of earthwork is often accompanied, at present, a small-sized tamping machine is often adopted for manual tamping, and the mode has high labor intensity of workers and low tamping efficiency; and a high-frequency vibration motor is also adopted to drive the tamping plate to vibrate and tamp, so that although the tamping efficiency is greatly improved, the energy consumption is larger.

SUMMERY OF THE UTILITY MODEL

According to the not enough among the above prior art, the utility model discloses the technical problem who solves is: provided is an excavator earthwork tamper with high earthwork tamping efficiency.

Excavator earthwork tamper, including quick change coupler, quick change coupler's bottom both ends all are fixed with the curb plate, hydraulic motor is installed in the outside of one of them curb plate, install the bearing in another curb plate, install the eccentric shaft in the bearing, the other end hookup hydraulic motor of eccentric shaft, it is connected with the sleeve to rotate on the eccentric shaft, be fixed with the connecting rod on the sleeve, be fixed with the bottom plate between the bottom of both sides board, the top of bottom plate is fixed with main guide sleeve, main guide sleeve sliding connection has main guiding axle, main guiding axle's upper end is articulated with the connecting rod, main guiding axle's lower extreme runs through the bottom plate and is fixed with the tamp board.

The bottom of four angles of the bottom plate is fixed with a guide sleeve, a guide shaft is connected in each guide sleeve in a sliding manner, and each guide shaft is fixed on the tamping plate.

And reinforcing ribs are fixed between the main guide sleeve and the two side plates.

And a protection plate is fixed between the two sides of the two side plates.

Compared with the prior art, the utility model beneficial effect who has is:

excavator earthwork tamper, can cooperate the excavator to carry out the earthwork tamping, not only reduced workman intensity of labour, still effectively improved tamping efficiency.
