Boom system for wheel type wet sprayer
The invention provides a boom system for a wheel type wet sprayer. The boom system for the wheel type wet sprayer comprises a rotary table arranged on a machine tool, and a boom device connected with the rotary table, wherein the rotary table is of a bilateral symmetry structure and comprises a rotary chassis, two vertical support plates and a horizontal support plate; a first through hole and a second through hole are respectively formed on the same height in the top parts of the vertical support plates; a third through hole is formed in the center of the horizontal support plate; the central points of the first through hole, the second through hole and the third through hole are located on the same vertical face; the tail end of a big arm and the rotary table are hinged at the first through hole and the second through hole; the front end of the big arm is hinged to the tail end of a small arm through two connecting rods; vertices of a quadrangle formed by one section of the front end of the big arm, one section of the tail end of the small arm and the two connecting rods are respectively located in a vertical face where the central axis of the big arm and the central axis of the small arm are jointly located. According to the boom system for the wheel type wet sprayer, the eccentric load phenomenon of all axle sleeves at hinged points is avoided, and the deformation of axle sleeve holes in the hinged points is controllable and uniform, so that the service life of a boom assembly and even the service life of the whole concrete wet spraying machine are improved.
