Screed plate suitable for small-sized paver

Abstract

A screed plate suitable for a small paver comprises a traction arm and a big arm, a front traction point of the traction arm is fixed, the big arm and a screed plate top plate are integrated, and one side of a screed plate bottom plate is fixedly connected with the lower end of a front end plate close to the front traction point to form a first mechanism; the other side of the screed bottom plate is hinged with the lower end of a rear end plate far away from the front traction point, and the upper end of the rear end plate is fixedly connected with the rear end of the big arm to form a second mechanism; a telescopic oil cylinder is installed between the first mechanism and the second mechanism, one end of the telescopic oil cylinder is connected with the first mechanism, the other end of the telescopic oil cylinder is connected with the second mechanism, and the telescopic oil cylinder drives the first mechanism to rotationally ascend or descend relative to the second mechanism with the hinge point between the rear end plate and the bottom plate of the screed as the rotation center. According to the paver, the elevation angle alpha between the screed plate and the material does not need to be controlled by driving a front traction point through a leveling oil cylinder, on the premise that the leveling oil cylinder is omitted and the front traction point is fixed, control over the elevation angle alpha is achieved, the paving quality is guaranteed, and meanwhile transportation, transition and installation of the small paver are facilitated.

Description

technical field [0001] The invention relates to a paver screed, in particular to a screed suitable for a small paver. Background technique [0002] The paver is one of the key equipment for building various grades of roads and municipal roads, as well as the base and surface layers of squares, airports, parking lots, dams and ditches. The asphalt concrete, stabilized soil and other mixed paving materials conveyed by the machine are leveled, shaped and pre-compacted to provide good working conditions for the subsequent further compaction of the road roller. [0003] Such as figure 1 As shown, the screed device of the paver needs to maintain an elevation angle α between the screed plate and the material during the paving operation. It is also the existence of this elevation angle that the resultant moment of the moment system formed by the acting force on the ironing device in a stable working state is zero. When the height of the front traction point remains unchanged and ...

AI Technical Summary

Problems solved by technology

[0004]The advantage of the small paver is that it is convenient to transition, but the working space for general operations is relatively narrow, and the leveling cylinder is used to adjust the height of the traction point to control the degree of paving On the one hand, it is not easy to install when it is thicker, and on the other hand, when paving in transitions and curves, you must always pay attention to protecting the leveling cylinder to avoid bending the cylinder due to excessive or uneven force, which limits the leveling to a certain extent. Small pavers take advantage of their flexibility
