Problems solved by technology
[0002] At present, when working on roads with relatively soft soil in road construction, in order to improve the pressure resistance of the road surface, tamping machines are used. Due to the different road surfaces that need to be tamped, some road surfaces require gravity tamping to meet the construction requirements, and some road surfaces only need to be compacted. Lighter tamping is enough, the existing tamping device cannot adjust the intensity of tamping and cannot meet the requirements of construction

A tamping force adjustable automatic tamping machine comprises a base plate; supporting plates are symmetrically and fixedly connected to the upper side of the base plate; the two supporting plates are both vertically arranged; the top ends of the two supporting plates are mutually and fixedly connected with a top plate; a lifting cylinder is arranged on the upper side of the top plate; a piston rod of the lifting cylinder vertically penetrates out from a yielding hole in the top plate downwards; and the tail end of the piston rod of the lifting cylinder is fixedly connected with a horizontally arranged battery iron. The tamping force adjustable automatic tamping machine has the beneficial effects that the lifting cylinder pushes the battery iron to attract a lifting plate and pulls the lifting plate upwards to reach a designated position to enable an electromagnet to be powered off; under the action of resilience forces and free falling forces of two second springs, the lifting platedrives a tamping block through a lifting rod to rapidly drop out from a yielding groove downwards so as to tamp a pavement; and the process is repeated till a tamping effect is realized; and accordingto the different upward lifting heights of the lifting plate, the tamping force can be adjusted.
Description
technical field [0001] The invention relates to engineering equipment, in particular to an automatic tamping machine with adjustable tamping force. Background technique [0002] At present, when working on roads with relatively soft soil in road construction, in order to improve the pressure resistance of the road surface, tamping machines are used. Due to the different road surfaces that need to be compacted, some road surfaces require gravity tamping to meet the construction requirements, and some road surfaces only need to be compacted. Lighter tamping is enough, and the existing tamping device cannot adjust the intensity of tamping, and cannot meet the requirements of construction. Contents of the invention [0003] The object of the present invention is to provide an automatic tamping machine with adjustable tamping force, so as to solve the problems raised in the above-mentioned background technology. [0004] To achieve the above object, the present invention provi...
