Description

Technical Field

[0001] The utility model relates to the technical field of road construction machinery, in particular to a material blocking device and a paver thereof. Background Art

[0002] A paver is a type of road paving construction equipment, primarily used for paving materials in the base and surface layers of roads. The material distribution system is a key component of the paver, primarily consisting of a distribution box, an auger, and a material retaining device. The material retaining device helps transfer paving material from the center of the trough to the sides, thereby improving the paver's construction quality. Since variable-width operations are common during road paving, such as when the pavement width increases and exceeds the paver's body width, the auger needs to be extended to meet road paving requirements. The material retaining device is used in conjunction with the auger, so it also needs to be appropriately extended to meet road paving requirements.

[0003] At present, existing pavers usually adopt a splicing method to achieve the widening and extension of the material blocking device. However, this method has the following disadvantages: 1. The material blocking device is mechanically connected to the paver, and the installation and disassembly process is time-consuming and labor-intensive; 2. When the width of the paved road surface increases and exceeds the width of the paver body, the auger needs to be extended to meet the road paving requirements. The material blocking device is used in conjunction with the auger, so the material blocking device also needs to be appropriately extended to meet the road paving requirements. Existing pavers usually adopt a splicing method to achieve the widening and extension of the material blocking device, and the construction efficiency is low; 3. During the transfer and transportation of the paver, the material blocking device also needs to be disassembled and stored, which is a cumbersome process and inconvenient to use. For this reason, a material blocking device and a paver thereof are proposed. Utility Model Content

[0007] Furthermore, the telescopic pull rod includes a first pull rod connected to the material baffle plate, and a second pull rod connected to the pull rod mounting seat, and the first pull rod and the second pull rod are constructed into a telescopic sleeve structure.

[0008] Further, the first pull rod and the material blocking plate are movably connected through a left-handed rod end joint bearing arranged at one end of the first pull rod away from the second pull rod, so that the first pull rod and the material blocking plate rotate relative to each other; and the second pull rod and the pull rod mounting seat are movably connected through a right-handed rod end joint bearing arranged at one end of the second pull rod away from the first pull rod, so that the second pull rod and the pull rod mounting seat rotate relative to each other.
