Abstract: A mechanism for swinging and steering a support leg for a pavement milling machine is provided having a milling machine frame, a swing rod, a steering rod, a first guiding rod and a second guiding rod, the support leg includes a support leg exterior sleeve and a interior sleeve, the support leg exterior sleeve is sleeved onto the support leg interior sleeve, the support leg interior sleeve rotates relative to the exterior sleeve; one end of the swing rod is hinged to the milling machine frame, and the other end is fixedly connected to the exterior sleeve; one end of the second guiding rod is hinged to the milling machine frame, the other end is hinged to one end of the first guiding rod, the other end of the first guiding rod is hinged to one end of the steering rod, and the other end of the steering rod is connected to the support leg interior sleeve.

Abstract: A locking device for a material conveyor includes a snapping part pivotally connected to a first conveying section or a second conveying section of the material conveyor and capable of pivoting in the pivoting direction of the second conveying section, the snapping part being provided with two hooks; a first post and a second post that are arranged on the second conveying section or the first conveying section not pivotally connected to the snapping part and are used for being matched with the hooks in hooking to fix the relative position of the second conveying section and the first conveying section when the second conveying section is in a folded or unfolded state; and a first power mechanism used for driving the snapping part to pivot.

Abstract: A telescopic screed includes main section and telescopic section screeds. The main section screed includes a screed frame and a base plate. The telescopic section screeds are arranged on the left side and/or the right side of the main section screed and include a cross slope framework, a cross slope driver, at least two multistage sliding pipes, a telescopic frame, a telescopic driver, a telescopic section frame, a telescopic section base plate and an elevation difference driver. The cross slope framework is pivotally connected with the main section screed to adjust the cross slope. The multistage sliding pipes are used for transversely guiding the telescopic frames to achieve the telescopic ability of the telescopic section screeds. The telescopic section frame is connected with the corresponding telescopic frame to move up and down to adjust the relative height between the telescopic section frame and the telescopic frame.

Abstract: The present invention discloses an anti-segregation auger and a paver, wherein the anti-segregation auger is provided on the paver and includes left and right basic augers and a center driving sprocket box, and a plow-shaped distributing device for distributing the mixture entering into the anti-segregation auger to both left and right sides is provided in front of the center driving sprocket box. Beneficial effects of the anti-segregation auger and the paver of the present invention lie in several aspects as follows: its plow-shaped distributing device can effectively regulate the flowing of the mixture, so that the asphalt mixture is stirred effectively, which reduces the accumulation and pressing of the mixture under the bottom of the center driving sprocket box and reduces longitudinal segregation of the asphalt mixture, thereby improving the paving quality of the road surface after paving.
