AI Technical Summary
There are two major problems in the use of existing gravel laying devices for road construction: one is that the gravel cannot be screened and filtered, resulting in a large gravel affecting the spreading effect; the other is that the discharge port is set up high, resulting in different accelerations when the gravel passes through the rotating column, which may collide with the box and spread to the surroundings, and needs to be subsequently closed and evenly spread.
A gravel laying device including a screening assembly and a laying assembly is designed. The screening assembly screens the gravel through filter plates and vibrators to ensure that only qualified gravel passes through; the laying assembly controls the uniform laying of gravel through rotating motors and couplings to avoid clogging and splashing.

Description
Technical Field
[0001] The utility model belongs to the technical field of highway maintenance equipment, in particular to a crushed stone paving device used for highway construction. Background Art
[0002] With the development of society, there are more and more vehicles on the road. After a long period of use, cracks or potholes usually appear on the road, so the road needs to be maintained. Among them, gravel spreading is a common maintenance method in highway maintenance. In order to evenly lay the gravel on the road surface, a gravel laying device for highway construction is needed.
[0003] A Chinese patent application with publication number CN218667066U discloses a gravel spreading device for highway maintenance, including a box body and a box cover rotatably connected to the upper end of the box body, the upper end of the box body is provided with a storage slot, the box body is provided with a circular slot, the circular slot is located directly below the storage slot, the inner top of the circular slot is provided with a first opening communicating with the storage slot, the inner bottom of the circular slot is provided with a second opening, a rotating column is rotatably connected in the circular slot, a plurality of storage slots are evenly distributed on the outer wall of the rotating column, a driving mechanism is provided in the rotating column, two inclined feed plates are provided at the bottom of the storage slot, and a vibration motor is fixedly connected to the lower side wall of the feed plate. The above utility model enhances the uniformity of gravel spreading through the provision of feed plates, servo motors and rotating columns, and can reduce the occurrence of blockages. At the same time, the gravel spreading speed can be set, which has promotion value.
[0004] However, it still has the following disadvantages in actual use:
[0005] The above-mentioned gravel spreading device for highway maintenance pours the gravel into the storage tank, and the gravel in the storage tank falls into the storage tank through the first opening for subsequent paving, but the gravel is not screened and filtered, resulting in some larger gravel affecting the effect of subsequent spreading;
[0006] The above-mentioned gravel spreading device for highway maintenance enhances the uniformity of gravel spreading and reduces the occurrence of blockages by setting a feed plate, a servo motor and a rotating column. However, the discharge port is set high, and the gravity acceleration of the gravel is different when passing through the rotating column. It will also collide with the box and then spread around, which requires subsequent collection and even spreading.
[0007] Therefore, we provide a crushed stone paving device for highway construction to solve the above-mentioned problems. Utility Model Content
