Principle and application of rammer

Answer:

Ramming machine power rammerCompaction machine for tamping compacted backfill soil by impact and impact vibration. Sub fire rammer, breaststroke tamping rammer and etc..Thermal rammerAccording to the principle of two stroke internal combustion engine, there are two upper and lower pistons in the cylinder. The upper piston is an internal combustion piston, and the lower piston is a buffer piston. The lower part of the cylinder is fitted with a rammer with an inclined bottom to deflect the vertical axis of the cylinder toward the front. The piston rod from the through hole of the cylinder cover in the middle reach of piston rod from the lower end of the cylinder and hammer out and integrated between cylinder and hammer with spring tension, direction and a handrail is arranged to control the rammer. The fire is rammed under the action of the explosive force of the combustible mixture, so it jumps off the ground from the top to the top, and then hits the ground and strikes the soil under the weight of itself. The hammer falls and the body moves forward step by step.
Quick impact rammerBy the motor through a speed reducer and a crank connecting rod mechanism drives the hammer impact to do fast movement of compacted soil, hammer jump off the ground, the operator can push the machinery forward, in order to reduce the vibration of the cylinder body, the vertical axis toward the deflection. Set buffer spring set.Tamper tamp of cohesive soil is better, but the hammer area is limited, is not suitable for large area earthwork compaction operations. For sand and gravel, the vibrating tamping machine should be used to tamper with the sand.
Electric breaststroke rammingMade by the principle of rotating inertia force, it is composed of rammer, rammer, eccentric block, belt pulley and motor. The motor and the driving part are mounted on the skid seat, and the rear end of the rammer frame is hinged with the drive shaft, and the rammer can swing up and down the shaft under the eccentric force of the eccentric block. The front end of the tamping frame is provided with a rammer, and when the rammer is swung downward, the soil is rammed and swung upwards to move the sled forward. Therefore, each impact compaction hammer frog once the body to move forward one step.
