Description

Technical Field

[0001] The utility model relates to the technical field of road construction, in particular to a large-thickness water-stable crushed stone base paving machine. Background Art

[0002] The main purpose of road construction is to promote the exchange of materials and personnel between the local area and the outside world, expand the scope of exchange, gather local popularity, increase the city's fame, promote population growth, and thus accelerate the local urbanization process. In the process of road paving, part of the road will be paved with water-stabilized crushed stone. Cement-stabilized crushed stone is a mixture of crushed stone with a certain grade, mixed with sufficient cement and water. After compaction and curing, when its strength meets the specified requirements, it is called cement-stabilized crushed stone.

[0003] The existing thick water-stable gravel base laying method uses a large container to hold the material silo, and then opens a large-diameter discharge port at the bottom. The water-stable gravel is poured out from the large-diameter discharge port and roughly laid on the base surface. The subsequent construction personnel use tools to rake the water-stable gravel to make it evenly laid on the base surface;

[0004] There are some problems with this artificially assisted laying method of water-stabilized gravel. For example, if the water-stabilized gravel is laid evenly, the moisture inside it will drain downwards, which may lead to uneven laying of the water-stabilized gravel. Artificially assisted laying has high requirements for construction workers. If the workers are inexperienced, it may lead to uneven laying. The discharge outlet of the water-stabilized gravel is fixed and the angle and direction cannot be adjusted. The water-stabilized gravel is prone to agglomeration during long-term storage, which affects the subsequent discharge operation. For this reason, we propose a large-thickness water-stabilized gravel base laying machine. Utility Model Content

[0016] Compared with the prior art, the utility model has the following beneficial effects: the large-thickness water-stable crushed stone base paving machine has the following advantages:

[0017] 1. Before paving the water-stabilized gravel for road construction, the external feeding equipment can be adjusted to put a specified amount of water-stabilized gravel into the mixing chamber. At this time, the external water supply equipment can be adjusted to discharge a certain amount of water into the mixing chamber.

The independent structure ensures the water content of the water-stabilized gravel and prevents the water-stabilized gravel from agglomerating during road construction.

[0018] 2. When the water-stabilized gravel just flows downward in the guide bucket, affected by gravity, the telescopic rod contracts and the guide bucket tilts to ensure that the water-stabilized gravel flow on the front side can be better aligned with the base surface. When no paving operation is performed, affected by the rebound force of the reset spring, the telescopic rod is pushed to extend and the guide bucket is reset. When the water-stabilized gravel just flows downward in the guide bucket, affected by gravity, the telescopic rod contracts and the guide bucket tilts to ensure that the water-stabilized gravel flow on the front side can be better aligned with the base surface.
