A provided paving machine comprises a casing and a front baffle plate disposed at the rear of the casing, a ramming mechanism installing space is formed between the front baffle plate and the casing; the paving machine also comprises a straining device which comprises an elastic straining piece mechanism arranged in the ramming mechanism installing space and a pulling force adjusting part disposed at the outside of the ramming mechanism installing space; a second end of an elastic straining piece is connected with the pulling force adjusting part; and the pulling force adjusting part possesses a first position enabling the elastic straining piece to be in a tensioning state and a second position enabling the elastic straining piece to be in a tensioning released state. According to the paving machine provided by the invention, by arranging the pulling force adjusting part at the exterior of the ramming mechanism installing space, the tensioning state and the tensioning released state of the elastic straining piece can be switched conveniently and rapidly, the time of the elastic straining piece in the tensioning state is reduced, the elasticity consumption of the elastic straining piece is reduced and the service life of the elastic straining piece is improved.
Description
technical field [0001] The invention relates to the field of road surface engineering equipment, in particular to a paver. Background technique [0002] When the paver is in construction, when the eccentric shaft of the tamper mechanism on the screed rotates, the punch at the lower end of the screed swings in the front and rear directions of the box body, resulting in a gap between the scraper on the front baffle and the punch, making When the material moves up and down along the punch, it enters the rammer mechanism. In order to prevent the material from entering the rammer system, a tensioning device is generally installed between the front baffle and the box to ensure that the scraper on the front baffle is tightly connected to the punch. Stick them together to prevent materials from entering the rammer mechanism and affect the quality of paving, and ensure the construction progress of the project. [0003] The tensioning devices in the prior art all utilize springs conn...
