Description

Technical Field

[0001] This utility model relates to the technical field of highway construction equipment, specifically a gravel spreading device for highway construction. Background Technology

[0002] Highway engineering refers to the surveying, measurement, design, construction, maintenance, and management of highway structures. Highway structures include roadbeds, pavements, bridges, culverts, tunnels, and other facilities. In highway maintenance and construction, paving is a crucial step in the formation of the pavement structure, involving a refined process and multi-machine collaborative operation. After paving, materials such as crushed stone need to be spread on the paved base layer to improve the load-bearing capacity and durability of the pavement. The process of spreading crushed stone requires the use of a crushed stone spreading device, which is a key piece of equipment for the uniform laying of stone materials.

[0003] Existing aggregate spreading devices mainly include self-propelled spreaders and suspended spreaders. Suspended spreaders are often used in conjunction with asphalt distributors to form an asynchronous aggregate seal construction system. The modular design facilitates quick assembly and disassembly. During spreading, aggregate is poured in through the top storage port and the internal storage space. As the suspended vehicle or drive structure moves along the road surface, the aggregate is then evenly spread out through the bottom discharge port to form a uniform aggregate layer on the base surface.

[0004] The aforementioned gravel spreading devices, whether self-propelled or suspended, are quite large in size. When spreading gravel over small areas such as local road repairs and small roads, it is impossible to use large vehicles and large-sized spreaders. Currently, the only option is to manually spread gravel onto the asphalt surface with shovels. However, manual labor is difficult to achieve even distribution of gravel, and it is labor-intensive, resulting in low work efficiency and poor quality of base layer spreading. Therefore, we propose a gravel spreading device for highway construction. Utility Model Content

[0026] This disclosure will now be described in detail with reference to the accompanying drawings and embodiments.

[0027] This utility model provides, for example Figure 1-4 The shown is a gravel spreading device for highway construction, including a main body 1. A spreading bracket 2 is fixed to one side of the bottom of the main body 1. The main body 1 includes a frame 101, and a material cavity 102 is opened inside the frame 101. A handle 103 is fixed to one end of the frame 101. A rotating shaft frame 104 is axled to one side of the bottom of the frame 101. Wheels 105 are fixed to both ends of the rotating shaft frame 104. A transmission sprocket 106 is sleeved and fixed on the outer wall of the rotating shaft frame 104, and a transmission chain 107 is sleeved on the outer wall of the transmission sprocket 106. One end of the transmission chain 107 is connected to a drive roller shaft 108, and one side of the drive roller shaft 108 is aligned with the discharge port 109.

[0028] To provide convenient use of this gravel spreading device for small-scale repairs, such as Figure 1-2 As shown, this gravel spreading device can be easily held by construction personnel through the handle 103 fixed on one side of the frame 101. At the same time, it can be used with the material cavity 102 opened inside the frame 101 to put gravel into it. The wheels 105 on both sides can be used with the axle frame 104 for easy gripping and driving. It can be used to spread gravel along a local area of ​​the road base. The actuating roller 108 can also work with the transmission chain 107 and the transmission sprocket 106 to drive simultaneously, forming a synchronous process of driving and spreading at the same time, which provides convenience.

[0029] like Figure 1-4 As shown, the spreading support 2 includes a spreading platform 201, and a diverter plate 202 is fixed on both sides of the inner wall of the spreading platform 201. A spreading plate 203 is fixed at the bottom of the spreading platform 201. A spreading hole 204 is opened inside the spreading plate 203. An extension platform 205 is distributed at both ends of the spreading platform 201. A secondary spreading plate 206 is fixed at the bottom of the extension platform 205. A side baffle 207 is fixed at one end of the extension platform 205. Screw holes 208 are opened inside both ends of the extension platform 205. Bolts 209 are connected to the inner wall of the screw holes 208.

[0030] To facilitate the application of aggregate in small areas such as localized road repairs and smaller roads, such as... Figure 1-4As shown, this gravel spreading device consists of a frame 101 and a spreading platform 201. The gravel evenly discharged from the spreading platform 201 is evenly distributed and spread along the diversion plate 202 inside the spreading platform 201 to the spreading plate 203. Then, the gravel is evenly spread through the spreading holes 204 of the spreading plate 203. The device can be adjusted according to the repair range through the extension platforms 205 at both ends. It is fixed by the bolts 209 and screw holes 208 of the extension platforms 205 at both ends. It can work with the secondary spreading plate 206 to spread the gravel evenly, providing convenience and being able to handle repair operations in multiple ranges, which is more conducive to the use of local repair operations.

[0031] In summary, when using this gravel spreading device, the user first adjusts the spreading platform 201 and the extension platforms 205 at both ends according to the size range of the local road surface to be repaired. The screw holes 208 of the extension platforms 205 are aligned with the screw holes 208 at both ends of the spreading platform 201. Then, the bolts 209 are tightened to complete the connection and adjustment. Next, the gravel is placed into the material cavity 102 of the frame 101, and the entire device is moved by holding the handle 103. When the frame 101 is moved, the wheels 105 rotate, causing the axle frame 104 to rotate, and the rotating axle frame 104 also drives the transmission chain. The rotating wheel 106 drives the meshing transmission chain 107 and the actuating roller shaft 108 synchronously through the transmission sprocket 106, causing the actuating roller shaft 108 to discharge the stone material synchronously along the discharge port 109 at the bottom of the cavity. After the stone material enters the inclined spreading table 201, part of it slides into the spreading plate 203 along the middle and is evenly spread through the spreading holes 204, while the two ends are swept into the two ends by the diversion plate 202 and are spread into the secondary spreading plate 206 from both sides of the spreading table 201 and the extension table 205. It is also evenly spread through the spreading holes 204, completing the stone spreading process.
