Improved portable roadbed tamper

Abstract

The invention discloses an improved portable roadbed tamper. The improved portable roadbed tamper comprises a lazy arm, and a tamping device arranged at the bottom of the lazy arm. The tamping devicecomprises an upper machine body and a lower machine body used for connecting with the upper machine body in a fitting mode, a sinking slot is formed in the bottom end face of the upper machine body, afist sliding cavity extending left and right is formed in the inner wall body of the upper machine body on the upper side of the sinking slot, and a second sliding cavity extending up and down is formed in the middle position in the first sliding cavity in a penetrating mode. The second sliding cavity is internally connected with a lifting sliding block in a sliding fit mode, the second sliding cavity at the top portion of the lifting sliding block is internally connected with a first spring in a pushing-pressing fit mode, a bevel through sliding slot is formed in the middle position in the lifting sliding block in a penetrating mode, pushing-pressing inclined sliding slots are symmetrically formed in the end faces of the left and right sides of the lifting sliding block on the lower sideof the bevel through sliding slot, the first sliding cavity is internally connected with bevel pushing-pressing inclined pushing-sliding blocks in a sliding fit mode, and the bevel pushing-pressing inclined pushing-sliding blocks stretch into the bevel through sliding slot and are connected in a sliding fit mode. The improved portable roadbed tamper is simple in structure, convenient to operate and convenient to disassemble, maintain and repair; and the maintenance efficiency is improved, and the working efficiency of tamping is improved.

Description

technical field [0001] The invention relates to the technical field of road construction machinery, in particular to an improved portable roadbed compactor. Background technique [0002] In road construction, in order to improve the pressure resistance of the road surface, the sand and gravel of the roadbed are generally tamped. The traditional tamping uses a manually moved vibratory compactor or a large hydraulic compactor. The manually moved vibratory compactor not only requires A large amount of labor, and the tamping accuracy is not high, the speed is slow, the tamping quality is poor, the working time is increased, the action surface is small, the energy consumption is relatively large through large-scale hydraulic tamping, the equipment utilization rate is low, and the construction cost of the road is increased. In addition, the traditional tamping machine has complex structure, poor operation flexibility, difficult disassembly and maintenance, and cannot meet the need...
