In the figure:

1. the device comprises an L-shaped vertical plate, 2, a bottom plate, 31, a movable plate, 32, a cavity, 33, a hinged plate, 4, a hydraulic cylinder, 5, a fixed shaft, 6, a through hole, 7 and a clamping groove.

The specific embodiment is as follows:

for the purpose of making the objects, technical solutions and advantages of the present utility model more apparent, the present utility model will now be described in further detail with reference to the accompanying drawings and the following examples, so that the public can better understand the method of practicing the present utility model, and the specific embodiments of the present utility model are as follows:

a paver hopper comprising: the hopper is formed by enclosing an L-shaped vertical plate 1 and a bottom plate 2, the two hoppers are symmetrically arranged on paver bodies on two sides of the conveyor, the telescopic plate 3 is arranged on the bottom plate 2 in a hinged structure mode, and two sides of the telescopic plate 3 are attached to the inner wall of the L-shaped vertical plate 1; the supporting mechanism is arranged on the bottom plate 2 and connected with the expansion plate 3 in a hinged structure manner, so as to open or close the expansion plate 3.

Specifically, the expansion plate 3 includes a movable plate 31 with a cavity 32, and a hinge plate 33 is embedded in the cavity 32 of the movable plate 31, and it should be noted that the cavity 32 is designed with three open surfaces, so as to meet the adhesion between one side of the hinge plate and an inner wall of the L-shaped vertical plate 1.
