Description

Technical Field

[0001] The utility model relates to the technical field of civil engineering machinery, in particular to a civil engineering machinery device for spreading materials. Background Art

[0002] Road construction is the lifeline of economic development, which can promote regional economic development and improve farmers' living standards. In the process of road construction, civil engineering machinery for paving materials is needed to pour concrete on the ground for paving. At present, there are many kinds of civil engineering machinery devices for paving materials on the market, but there are still some shortcomings;

[0003] For example, in actual use, civil engineering machinery devices generally used for spreading materials use a scraper plate to scrape the concrete. The scraper plate is not easy to adjust up and down, and the height of each road construction is different, lacking the flexibility of adjusting the height of the scraper plate. At the same time, when the concrete is scraped, the concrete materials on the left and right sides will fall to both sides due to the pressure of the scraper plate, which will greatly waste the concrete material. In addition, there is a lack of compaction link after the concrete is scraped. If it is not compacted, there will be holes between the poured concrete. Once there is vibration on it, it will cause problems such as cracking of the ground. Therefore, we propose a civil engineering machinery device for spreading materials to solve the above problems.

DETAILED DESCRIPTION

[0024] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0025] See also Figure 1-4 The utility model provides a technical solution: a civil engineering mechanical device for spreading materials, comprising: a cart 1, a fixed plate 2, a rotating rod 3, a connecting rod 4, a supporting rod 5, a moving frame 6, a scraping plate 7, a connecting belt 8, a first pulley 9, a motor 10, a second pulley 11, a supporting frame 12, an electric telescopic rod 13, a limiting plate 14, a connecting shaft 15, a fixed rod 16, a pressing roller 17 and a scraping plate 18;

[0026] like Figure 1 , Figure 2 and Figure 4As shown in the figure, by setting casters under the cart 1, it is very convenient to pull the cart 1 to the road that needs to be paved. Because the rotating rod 3 is symmetrically installed inside the cart 1, the motor 10 connected to the left side of the rotating rod 3 at the rear of the cart 1 is first turned on, that is, the motor 10 will drive the connecting rotating rod 3 to rotate on the right side of the fixed plate 2, and the left side of the rotating rod 3 at the rear of the cart 1 is also connected to the first pulley 9. Therefore, when the rotating rod 3 rotates, the first pulley 9 will also rotate together. A connecting belt 8 is set on the outside of the first pulley 9, and the connecting belt 8 connects the first pulley 9 and the second pulley 11. The connecting belt 8 is in the shape of an "8", that is, the second pulley 11 connected by the connecting belt 8 will also rotate, and the second pulley 11 connects the cart 1, that is, the rotating rod 3 arranged on the front and rear sides of the cart 1 will rotate simultaneously through the connection of the first pulley 9 and the second pulley 11, and at the same time, the rotating rod 3 is connected to the connecting rod 4, and the connecting rod 4 will also rotate. Secondly, the connecting rod 4 is connected to the supporting rod 5, and the connecting rod 4 will drive the supporting rod 5 to rotate above the fixed plate 2. At the same time, a moving frame 6 is arranged inside the fixed plate 2, and a disc block is arranged in the middle of the moving frame 6. The disc block in the middle of the moving frame 6 is engaged with the upper middle part of the supporting rod 5, that is, when the supporting rod 5 rotates up and down, the moving frame 6 will be driven to move up and down inside the fixed plate 2. The lower end of the moving frame 6 is connected to the scraping plate 7, that is, when the moving frame 6 moves downward, it will push the scraping plate 7 to move downward, so that the scraping plate 7 and the concrete laid on the road are closely fitted;

[0027] like Figure 1 , Figure 2 and Figure 3 As shown in the figure, after the scraper plate 7 and the concrete laid on the road are closely fitted, since the support frame 12 is symmetrically fixedly installed on the front and rear sides of the cart 1, an electric telescopic rod 13 is installed below the support frame 12, and the output end of the electric telescopic rod 13 is connected to the limit plate 14. When the electric telescopic rod 13 is opened, the output end of the electric telescopic rod 13 can push the limit plate 14 to move downward, so that the limit plate 14 is engaged with the front and rear sides of the concrete laid on the road, and then the inside of the limit plate 14 is closely fitted with the scraper plate 7;

[0028] In addition, a connecting shaft 15 is provided inside the right side of the cart 1. The motor 10 connected to the rear of the connecting shaft 15 is turned on and the motor 10 is started, which will cause the connecting shaft 15 to rotate inside the right side of the cart 1. The front and rear sides of the outer side of the connecting shaft 15 are connected to the fixing rods 16, which are connected to the clamping roller 17 and the scraper plate 18. That is, the rotation of the connecting shaft 15 can drive the fixing rod 16, the clamping roller 17 and the scraper plate 18 to rotate downward, so that the clamping roller 17 rotates to fit closely with the concrete laid on the road surface. At this time, pull the left side. The moving cart 1 and the scraper plate 7 will first scrape the laid concrete, and the limit plate 14 can limit the concrete on both sides of the road, which can effectively prevent the concrete on both sides of the road from falling and save concrete materials. The clamping roller 17 rolls on the scraped concrete to compact the concrete, ensuring that the road surface will not sink or break. The outer right side of the clamping roller 17 is tightly fitted with the scraper plate 18, which can effectively scrape off the concrete adhered to the surface of the clamping roller 17, ensuring the normal operation of the scraper plate 18.
