Description

Technical Field

[0001] This utility model relates to the field of concrete mixing technology, specifically to a high-efficiency concrete mixing device for bridge construction. Background Technology

[0002] A concrete mixing plant for bridge construction is a mechanical device that mixes cement, aggregates (such as sand and gravel), water, and other admixtures in a certain proportion to prepare concrete that meets the requirements of bridge engineering. It is widely used in the construction of infrastructure such as bridges, roads, and railways, especially for bridge projects that have high requirements for concrete quality and construction efficiency.

[0003] In existing concrete mixers, aggregates are often not evenly distributed during the feeding process, resulting in localized accumulation or insufficient aggregates. Traditional feeding methods may involve directly pouring aggregates into the mixer, leading to uneven distribution. This uneven distribution causes the mixer to require a longer time to achieve uniform mixing of aggregates, cement, and water, thus reducing mixing efficiency. Furthermore, localized aggregate accumulation increases mixing resistance, further affecting mixing efficiency. Therefore, a high-efficiency concrete mixing device for bridge construction is proposed. Utility Model Content

[0030] The second drive motor 18 is fixedly installed on the lower left side of the crossbar 13 by a fixing bracket. The output end of the second drive motor 18 is equipped with a second drive gear 19, and the second transmission gear ring 17 is meshed with the second drive gear 19.

[0031] A strip-shaped shell 20 is fixedly installed at the lower end of the rotating tube 15. A third drive motor 22 is fixedly installed on both sides of the upper end of the strip-shaped shell 20 through a fixing bracket. A reciprocating screw 23 is installed at the output end of the third drive motor 22. A baffle 25 is slidably installed at both ends inside the strip-shaped shell 20. A slider 24 is fixedly installed at the upper end of the baffle 25 and is slidably connected to the strip-shaped shell 20. The slider 24 is connected to the reciprocating screw 23 through a threaded engagement.

[0032] Please see Figure 2 There are four stirring racks 10, and the four stirring racks 10 are distributed in a ring at the lower end of the inner transmission ring 9.

[0033] Please see Figure 2 and Figure 3 A triangular guide block 21 is provided in the middle of the lower end of the strip shell 20, and the triangular guide block 21 is fixedly connected to the strip shell 20 so as to guide the aggregate to both ends of the strip shell 20.

[0034] Please see Figure 1 and Figure 2 The upper end of the rotating pipe 15 is provided with a guide pipe 16, and the guide pipe 16 is fixedly connected to the crossbar 13 through a bracket. The guide pipe 16 is used to guide the aggregate into the rotating pipe 15.

[0035] Please see Figure 1 and Figure 2 Support legs 3 are provided on both sides of the lower end of the outer ring 2, and the support legs 3 are fixedly connected to the outer ring 2. The support legs 3 are used to support the outer ring 2 and the outer barrel 1.

[0036] Please see Figure 1 and Figure 2 A shut-off valve 4 is provided at the lower end of the outer bucket 1, and the shut-off valve 4 is fixedly connected to the outer bucket 1. The shut-off valve 4 is used to control the discharge of concrete from the lower end of the outer bucket 1.

[0037] This scheme involves adding cement and admixtures into the outer container 1, starting the first drive motor 5 to rotate the first drive gear 6, and engaging the first transmission gear ring 7 with the first drive gear 6 to rotate the inner transmission ring 9 and the mixing frame 10. The cement and admixtures are then mixed by the mixing frame 10 and the mixing blades 11. Water is then injected to wet the cement, forming a cement slurry. The aggregate is conveyed to the guide pipe 16 via a conveying device. Simultaneously, starting the second drive motor 18 causes the second drive gear 19 to rotate, and engaging the second transmission gear ring 17 with the second drive gear 19 to rotate the rotating pipe 15 and the strip shell 20. The aggregate falls along the guide pipe 16 into the rotating pipe 15 and then downwards into the strip shell 20. Under the rotation of the shell 20, the aggregate is subjected to centrifugal force and rotates downwards, falling into the outer barrel 1. The third drive motor 22 is started to make the reciprocating screw 23 rotate. The slider 24 and the reciprocating screw 23 are connected by threads, and the slider 24 and the shell 20 are connected by sliding, which converts the rotational motion of the reciprocating screw 23 into the linear reciprocating motion of the slider 24 and the baffle 25. This changes the near and far position of the baffle 25, thereby making the aggregate thrown far and near under the centrifugal force, so that the aggregate is evenly fed along the ring. According to the slump requirements of the concrete, the remaining water is added for mixing. After the concrete is mixed, the discharge of the concrete is controlled by the shut-off valve 4.
