Description

Technical Field

[0001] The utility model relates to the technical field of rammer air plugs, in particular to an environmentally friendly rammer with a floating balance air plug. Background Art

[0002] Impact rammer: A compaction machine that uses impact and vibration to compact backfill soil in layers. It is divided into electric impact rammer, gasoline impact rammer and vibration impact rammer, etc. It is made based on the principle of rotational inertia force and consists of a rammer, a rammer frame, an eccentric block, a pulley and an electric motor. When the impact rammer and the flat plate rammer are working, the staff needs to hold the handrail to control the work of the impact rammer.

[0003] Among them, a straight-discharge air plug is used in the rammer to realize gas conversion between the rammer body and the outside. The working method of the existing rammer air plug is: the air plug is vertically installed on the rammer, and a T-shaped straight-discharge port is opened in the air plug. The gas enters and exits the air plug through the straight-discharge port to realize gas conversion between the rammer body and the outside. The traditional air plug keeps the rammer and the outside in a connected state at all times. The external air together with the impurities in the air can enter the rammer through the air plug. The impurities can easily cause the air plug to be blocked, affecting the gas conversion effect of the rammer.

[0004] To this end, we propose an environmentally friendly rammer with a floating balancing air plug. Utility Model Content

[0013] The utility model has at least the following beneficial effects:

[0014] 1. Gas enters through the circular through hole on the breathing valve body, pushing the floating piston to move horizontally along the outer wall of the guide rod. The floating piston compresses the filter sponge in the breathing valve body, and the air leakage hole and the exhaust hole on the breathing valve body are connected to each other, and then the gas in the breathing valve body is discharged through the exhaust hole. When no gas is generated, the breathing valve body is in a vertically installed state, and the floating piston moves down along the guide rod under the influence of its own weight to close the circular through hole of the breathing valve body.

[0015] The floating piston can move in the breathing valve body. When the air leakage hole and the exhaust hole are aligned, the breathing valve body can be exhausted. The floating piston can close the circular through hole of the breathing valve body to achieve closure. A filter sponge is placed on the outer wall of the exhaust hole to prevent impurities in the air from entering the breathing valve body and preventing the impurities from causing blockage of the breathing valve body.

[0016] 2. Insert the sealing cover into the tail end of the breathing valve body. Under the action of the elastic part in the inner tube, push the push rod through the inner tube and insert it into the groove of the clamping ring, so as to fix the position of the sealing cover. At the same time, the sealing cover closes the breathing valve body. The sliding pin drives the push rod and the clamping ring to separate, and the sealing cover can be removed.

[0017] The detachable design of the sealing cover makes it easy to replace the filter sponge and the floating piston in the breathing valve body. The elastic force of the elastic part is used to push the push rod to move and connect the clamping ring to achieve the installation of the sealing cover, changing the traditional threaded connection method of the sealing cover and making the operation convenient.
