Abstract
Description
Technical Field
[0001] This utility model relates to the field of material mixing technology, specifically a device for mixing and configuring civil engineering materials. Background Technology
[0002] Civil engineering materials refer to all infrastructure planning, construction, and maintenance related to water, soil, and culture, which requires mixing various materials according to a mix ratio.
[0003] Chinese Utility Model Publication No. CN219647303U discloses a civil engineering material mixing and preparation device, which includes a box body. Inside the box body, two rolling bearing sleeves are equidistantly connected by slots. The same mixing tank is fitted inside the two rolling bearing sleeves. A connecting cylinder is welded to the bottom of the mixing tank. A rolling bearing I is fitted outside the connecting cylinder. Both ends of the rolling bearing I are connected to the two sides inside the box body by welded fixing rod bolts. A rolling bearing II is installed at the bottom inside the box body by bolts. A mixing rod is fitted to the top of the rolling bearing II.
[0004] Although the device improves the mixing effect to some extent by alternating the rotation of the stirring rod and the mixing box, larger particles at the bottom of the mixing box cannot effectively move upwards due to the pressure from the material above and their own gravity. Instead of being broken down into smaller particles by the stirring rod above and mixed with the smaller particles above, they rotate in the area where the large particles accumulate at the bottom. Since the device lacks a mechanism to crush large particles and a mechanism to guide the material at the bottom to flow upwards, the mixing effect is not very good and there is room for improvement.

[0015] (III) Beneficial Effects
[0016] Compared with the prior art, the present invention provides a mixing and preparation device for civil engineering materials, which has the following beneficial effects:
[0017] This civil engineering material mixing and preparation device uses a second motor to drive a pusher plate to move.

The material is then scraped away by the scraper plate for further mixing. This process crushes the large particles at the bottom of the mixing box and guides them to the upper middle part of the mixing box for further stirring and mixing, thereby improving the mixing effect.

[0025] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0026] Please see Figure 1-6This utility model discloses a mixing and preparation device for civil engineering materials, including a mixing tank 1. A feed pipe 15 is installed at the top of the mixing tank 1, through which workers add materials. A first connecting rod 2 is rotatably connected to the bottom center of the mixing tank 1. A first motor 3 is installed at the lower part of the first connecting rod 2, and several stirring rods 4 are installed on the first connecting rod 2. When the first motor 3 is started, it rotates, driving the upper first connecting rod 2 to rotate, and causing the stirring rods 4 to stir the materials in the mixing tank 1, thus allowing the materials to enter the mixing tank. In the mixing process, second connecting rods 5 are rotatably connected to both sides of the bottom of the mixing box 1 and are connected together by a belt 6. A second motor 7 is installed at the lower part of one of the second connecting rods 5. When the second motor 7 is started, it rotates, driving the second connecting rod 5 to rotate, and then driving the other second connecting rod 5 to rotate via the belt 6. Several extension plates 8 are provided on the second connecting rod 5, and a pusher plate 9 is provided at one end of each extension plate 8. When the second connecting rod 5 rotates, it drives the pusher plate 9 to rotate through the extension plates 8. The pusher plate 9 includes a first receiving... When the force section 10 and the pusher plate 9 rotate, the first force section 10 collides with the oncoming material. The end face of the first force section 10 is arc-shaped. After the collision, the material flows upward along the arc surface of the first force section 10 at its own flow velocity, and then moves to the upper middle part of the mixing box 1, where it mixes with other materials. The pusher plate also includes a second force section 11, which is arranged opposite to the first force section 10. The speed of the second motor 7 is less than the speed of the first motor 3, so that the flow velocity of the material is faster than the speed of the second rotating rod. When the first force section 10... When the force unit 10 rotates to the same direction as the material rotation, the second force unit 11 faces the oncoming material. The material catches up with the pusher plate 9 and impacts the second force unit 11. The end face of the second force unit 11 is inclined. After the collision, the material flows upward along the arc surface of the second force unit 11 at its own flow velocity. A scraper plate 12 is provided at the lower part of the pusher plate 9. The lower end face of the scraper plate 12 is in contact with the bottom of the mixing box 1. The scraper plate 12 rotates with the pusher plate 9 and scrapes away the material at the bottom of the mixing box 1.
[0027] Several extension plates 8 are equipped with crushing devices at one end. The crushing devices include a support 13 connected to the extension plates 8. The lower part of the support 13 is rotatably connected to a crushing roller 14, which rolls at the bottom of the mixing box 1. The support 13 rotates with the extension plates 8, and then drives the crushing roller 14 connected to it to roll at the bottom of the mixing box 1, crushing the large particles that have settled at the bottom of the mixing box 1. Then, under the scraping of the scraper, the crushed material is scraped away and moved by the flow of the material above, and mixed with other materials. The lower part of the mixing box 1 is connected to a discharge pipe 16 and is equipped with a valve. When the material is completely mixed, the valve on the discharge pipe 16 is opened, and the material is discharged into a designated container through the discharge pipe 16. The lower part of the mixing box 1 is equipped with a support plate to support the mixing box 1 and to cover the first motor 3, the second motor 7, and other devices.
[0028] In summary, when using this civil engineering material mixing and preparation device, the operator adds materials to the mixing tank 1 through the feed pipe 15, then starts the first motor 3. The first motor 3 rotates, driving the first connecting rod 2 and the stirring rod 4 to rotate, thus mixing the materials in the mixing tank 1. Then, the second motor 7 is started, driving the second connecting rod 5 to rotate, which in turn drives another second connecting rod 5 to rotate via the belt 6. Then, the extension plate 8 connected to the device drives the pusher plate 9 to rotate. After the first force-bearing part 10 of the pusher plate 9 rotates to the opposite direction to the material, it collides with the oncoming material, and the material moves upward along the arc surface of the first force-bearing part 10. After moving and rotating to the same direction as the material, the second force-bearing part 11 of the pusher plate 9 faces the material. The material impacts the second force-bearing part 11 and moves upward along the arc surface of the second force-bearing part 11. It flows upward along the first force-bearing part 10 to the middle and upper part of the mixing box 1 for mixing. At the same time, the crushing roller 14, driven by the support 13 and the extension plate 8, crushes the large particles at the bottom of the mixing box 1 into small pieces. Under the rotation of the scraper plate 12, the material is scraped away and mixed with the material above. When the material is completely mixed, the valve on the discharge pipe 16 is opened, and the material is discharged into the designated container through the discharge pipe 16.
