Description

Technical Field

[0001] This utility model relates to the field of engineering machinery technology, and in particular to a premixed crushed stone spreading device. Background Technology

[0002] Heavy-load bridge traffic sections, such as urban expressways, highway mainlines, and industrial heavy-load bridge decks, bear high-volume vehicle loads for extended periods, placing high demands on pavement strength. The fatigue performance of the asphalt pavement layer directly affects the final performance and service life of the steel bridge deck. The existing steel bridge deck construction process is roughly as follows: construction preparation → removal of the original pavement waterproof layer → shot blasting and rust removal → cleaning and roughness testing → primer spraying → bond strength testing → waterproof layer spraying → thickness and viscosity strength testing → topcoat spraying → asphalt concrete paving → penetration, penetration increment, and flexural strain testing → spreading pre-mixed aggregate → steel wheel compaction → joint and boundary treatment → installation of the wearing course. When spreading aggregate, to enhance the adhesion between the aggregate and the asphalt pavement, the aggregate is pre-mixed and coated with base asphalt. This reduces the flowability of the aggregate, affecting the spreading effect, and needs improvement. Utility Model Content

[0003] To address the problems mentioned in the background art, the purpose of this utility model is to provide a premixed crushed stone spreading device.

[0004] To achieve the above objectives, the technical solution of this utility model is as follows:

[0005] A premixed crushed stone spreading device includes a hopper. A connector for mounting the hopper to a traveling vehicle is provided on the front side of the hopper. A rectangular discharge port is provided at the bottom of the hopper. A gate mechanism for adjusting the discharge port width is provided inside the hopper. A rotating shaft passes through the left and right side walls of the hopper and is rotatably connected to the side walls of the hopper. Several agitator blades are detachably mounted on the rotating shaft inside the hopper. The agitator blades are evenly arranged around the rotating shaft. Corresponding blades are provided on the outer side walls of the hopper. A sleeve is fixedly connected at the position through which the rotating shaft passes. The sleeve is coaxially arranged with the rotating shaft. A swing arm is rotatably sleeved on the sleeve. A shaft is rotatably installed between the ends of the two swing arms away from the sleeve. The rotating shaft and the shaft are parallel. Both ends of the shaft are coaxially connected to a drive sprocket. Both ends of the rotating shaft are coaxially connected to a driven sprocket. The two drive sprockets and the two driven sprockets are connected by chain drive. A pressure roller is coaxially connected to the outside of the shaft.

[0006] Furthermore, the gate mechanism includes an adjusting plate and an electric cylinder. The hopper has a flat bottom plate, which is inclined. The front side of the bottom plate of the hopper is the lower side, and the discharge port is located on the lower side of the bottom plate of the hopper. The adjusting plate slides against the bottom plate of the hopper and passes through the rear side plate of the hopper. The rear side of the adjusting plate is bent to form a connecting part. The cylinder body of the electric cylinder is fixedly installed on the outside of the bottom plate of the hopper, and the end of the telescopic rod of the electric cylinder is fixed to the connecting part. By operating the electric cylinder, the adjusting plate can be moved obliquely upward or downward.

[0007] Furthermore, a discharge cylinder matching the shape of the discharge port is fixedly connected to the outside of the discharge port, and the discharge cylinder is vertically arranged.

[0008] Furthermore, an anti-detachment end cap is detachably installed on the end face of the sleeve. The anti-detachment end cap is clearance-fitted with the swing arm and is used to prevent the swing arm from detaching from the sleeve.

[0009] The beneficial effects of this utility model are as follows: the hopper is installed on the traveling vehicle through the connecting parts, and the pressure roller touches the ground due to its own weight. When the traveling vehicle moves forward, the pressure roller can crush the spread gravel, strengthen the adhesion between the gravel and the asphalt pavement. At the same time, the rotation of the pressure roller will drive the rotating shaft to rotate, allowing the mixing paddle to mix the gravel in the hopper, improve the flowability of the gravel, and ensure the spreading effect of the gravel.

Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of the present utility model are within the protection scope of the present utility model.

[0015] like Figures 1-3 As shown, a premixed crushed stone spreading device includes a hopper 1. The upper part of the hopper 1 is rectangular shell-shaped. The bottom plate of the hopper 1 is inclined, and the front side of the bottom plate of the hopper 1 is the lower side. A rectangular discharge port 11 is opened on the front side of the bottom plate of the hopper 1. The long side of the discharge port 11 is parallel to the long side of the hopper 1. A connector is horizontally fixed to the front outer wall of the hopper 1. The connector is a horizontally arranged connecting plate 12. The connecting plate 12 has several mounting holes 121. The connecting plate 12 is used to fix the hopper 1 to a traveling vehicle. (Not shown in the figure) At the tail end, a rectangular adjusting plate 2 is slidably attached to the bottom plate of hopper 1. The adjusting plate 2 can slide along the inclined direction of the bottom plate of hopper 1. The adjusting plate 2 passes through the rear side plate of hopper 1, and the rear side edge of the adjusting plate 2 is bent downward to form a connecting part 21. An electric cylinder 3 is fixedly installed on the outside of the bottom plate of hopper 1. The electric cylinder 3 is connected to external power generation equipment and control equipment (not shown in the figure). The telescopic rod of the electric cylinder 3 is parallel to the inclined direction of the bottom plate of hopper 1. The telescopic rod of the electric cylinder 3 is fixedly connected to the connecting part 21. The electric cylinder 3 is controlled by... The adjusting plate 2 can be moved diagonally upwards or downwards to adjust the discharge width of the discharge port 11. A rotating shaft 4 is installed inside the left and right side walls of the hopper 1. The rotating shaft 4 is parallel to the long side of the discharge port 11. The rotating shaft 4 is rotatably connected to the side wall of the hopper 1 via bearings. Several stirring paddles 5 are detachably installed on the rotating shaft 4 inside the hopper 1, and the stirring paddles 5 are evenly arranged around the rotating shaft 4. Sleeves 13 are fixedly connected to the left and right outer side walls of the hopper 1 at the positions where the rotating shaft 4 passes through. The sleeves 13 are coaxially arranged with the rotating shaft 4, and a rotating sleeve 13 is rotatably fitted onto the sleeve 13. The two swing arms 6 are connected by a bearing between the ends of the two swing arms 6 away from the sleeve 13. The shaft 4 is parallel to the shaft 7. The two ends of the shaft 7 are detachably mounted with a drive sprocket 8 by bolts. The drive sprocket 8 is coaxial with the shaft 7.

The position of the adjusting plate 2 is adjusted by the electric cylinder 3, thereby adjusting the discharge width of the discharge port 11. When the traveling vehicle moves forward, the pressure roller 71 can crush the spread gravel, strengthen the adhesion between the gravel and the asphalt pavement. At the same time, the rotation of the pressure roller 71 will drive the rotating shaft 4 to rotate, allowing the mixing paddle 5 to mix the gravel in the hopper 1, improve the flowability of the gravel, and ensure the spreading effect of the gravel.

[0017] Furthermore, a discharge cylinder 111 matching the shape of the discharge port 11 is fixedly connected to the outside of the discharge port 11.
