Embodiment Construction

[0023] Figure 1 to Figure 3 It shows an embodiment of an angle-adjustable paver traction arm of the present invention, which comprises a front traction arm 1, a boom 3 and a leveling cylinder 4, and the leveling cylinder 4 is installed at the front end of the front traction arm 1. The rear end of the arm 3 is equipped with a boom lifting oil cylinder 5, and the front end of the boom 3 is hinged to the middle part of the front traction arm 1, and an adjusting device 2 that can adjust the angle between the front traction arm 1 and the boom 3 is provided. The device 2 adjusts the angle between the front traction arm 1 and the main arm 3 to realize the adjustment of the elevation angle of the paver screed. This structure does not need the rear main arm of the existing paver traction arm, which simplifies the traction The structure and installation steps of the arm reduce mechanical failure points and make the operation of the equipment more stable and reliable.

Abstract

The invention discloses a tow arm of a paver capable of adjusting an angle. The tow arm comprises a front tow arm, a large arm and a leveling oil cylinder, wherein, the leveling oil cylinder is arranged on the front end of the front tow arm; the front end of the large arm is hinged with the front tow arm; and an adjusting device capable of adjusting an included angle between the front tow arm andthe large arm is arranged between the front tow arm and the large arm. The tow arm of the paver capable of adjusting the angle has the advantage of simple and compact structure, and is convenient in installation and adjustment. The invention further discloses the paver. The paver comprises a frame and an ironing plate, wherein, the ironing plate is arranged on the frame through the tow arm of thepaver capable of adjusting the angle.

Description

technical field [0001] The invention relates to engineering machinery for road surface operation, in particular to an angle-adjustable traction arm of a paver and a paver. Background technique [0002] The operating device of the paver is a screed. When the paver is working, the screed has a certain elevation angle to ensure the smooth progress of the paving operation. The change of the elevation angle will cause the change of the paving thickness. In the existing paver, the change of the elevation angle is usually by adjusting the mechanical angle between the rear arm and the screed plate hinged on the screed; The front boom of the paver is usually divided into front and rear parts. The front part of the boom is connected to the leveling cylinder, and the rear part of the boom is connected to the front part of the boom by bolts, or the front part of the boom can be changed through the position of the screw hole. and a certain angle to the rear of the upper arm. And in the...
