Description

Technical Field

[0001] This utility model relates to the field of concrete processing technology, specifically to a device for the efficient preparation and molding of colored permeable concrete. Background Technology

[0002] Colored permeable concrete is an environmentally friendly building material with a special structure. It not only possesses the load-bearing capacity of ordinary concrete but also effectively allows rainwater to infiltrate into the ground, helping to replenish groundwater and reducing the risk of surface runoff and urban flooding. It is characterized by its high porosity and is typically composed of coarse aggregate, cement, additives (such as pigments), and a small amount of fine aggregate. Sometimes, special reinforcing agents are added to ensure the material's strength. Because permeable concrete mixtures are relatively dry and stiff, forced-action mixers are recommended to ensure uniform mixing of the components; these mixers offer higher mixing efficiency.

[0003] Patent CN214982021U discloses a forced mortar mixer, including a base, a mixing drum on the base, an inlet and an outlet on the mixing drum, a mixing shaft rotatably mounted inside the mixing drum, a drive source on the mixing drum for driving the mixing shaft to rotate, a groove formed along the axial direction of the mixing shaft at the end away from the drive source, multiple first water outlet holes communicating with the groove on the side wall of the mixing shaft, a water supply pipe slidably mounted along the axial direction of the mixing shaft within the groove, a second water outlet hole on the side wall of the water supply pipe, and an external water pipe connected to the water supply pipe. This design facilitates comprehensive cleaning of the mixing drum's interior.

[0004] However, the concrete preparation and molding device in the above technology still has the following problems: When forced mixing is carried out, a certain amount of water needs to be injected into the mixing drum to participate in the mixing. When the mixing inside the mixing drum is mixed, a certain proportion of water needs to be injected to participate in the mixing. When this water seeps out from the discharge port at the bottom of the mixing drum, it will reduce the amount of water inside, causing the concrete mortar prepared inside the mixing drum to be drier than the preset, thus reducing the quality of the prepared concrete mortar. Utility Model Content

[0005] To address the shortcomings of existing technologies, this invention provides an efficient preparation and molding device for colored permeable concrete, which prevents water from flowing out of the mixing tank, ensures a more precise ratio of raw materials in the prepared concrete mortar, and improves the quality of the mixed concrete mortar.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a high-efficiency preparation and molding device for colored permeable concrete, comprising a mixing frame and a mixing drum installed on the mixing frame. A mixing motor is installed on the mixing frame. Both ends of the mixing drum are rotatably connected to the mixing frame via rotating shafts. The output shaft of the mixing motor passes through the rotating shaft and the mixing drum and is fixedly connected to the mixing rod inside the mixing drum. A material inlet is opened through the top of the mixing drum, and a sealing plate is connected to the outside of the material inlet. A tilting motor is fixedly connected to the side of the mixing frame away from the mixing motor. The output shaft of the tilting motor passes through the mixing frame and is fixedly connected to the rotating shaft at the end of the mixing drum.

[0007] Furthermore, the flip motor is a lock-up motor.

[0008] Furthermore, two fixing blocks are fixedly connected to both ends of the outer surface of the mixing tank. A limit rod is fixedly connected between the two fixing blocks at the same end. Limit holes are opened at both ends of the sealing plate. The two limit rods are slidably connected to the two limit holes respectively. A compression spring is sleeved on the outside of the two limit rods. One end of the two compression springs is fixedly connected to both ends of the sealing plate on the same side. The other end of the two compression springs is fixedly connected to the adjacent fixing blocks respectively.

[0009] Furthermore, a stop bar is fixedly connected to the side of the mixing rack away from the compression spring. The stop bar is located below the mixing tank. A compression rod is fixedly connected to the end of the sealing plate away from the compression spring and the side away from the mixing tank. The compression rod abuts against the stop bar.

[0010] Furthermore, two symmetrically arranged connecting blocks are fixedly connected to the middle position of the sealing plate near the compression spring. Each of the two connecting blocks has a flip hole on its adjacent side. A hook is connected between the two connecting blocks. A connecting shaft is fixedly connected to both sides of one end of the hook. The two connecting shafts are rotatably connected to the two flip holes respectively. A hook block is fixedly connected to the outer wall of the mixing tank. The hook block is matched with the hook.

[0011] Furthermore, a spring groove is provided on the inner wall of the flip hole, and a torsion spring is connected in the spring groove. The torsion spring is fitted with a connecting shaft, one end of the torsion spring is fixedly connected to the spring groove, and the other end is fixedly connected to the connecting shaft.

[0012] Furthermore, the hook is located away from the end of the connecting block and has an inclined surface on the side closest to the mixing tank.

[0013] Compared with the prior art, the present invention has the following beneficial effects:

[0014] This efficient colored permeable concrete preparation and molding device has a material inlet on the mixing tank. When adding materials, the mixing tank is rotated by a flipping motor so that the material inlet faces upward. After mixing is completed, the material inlet is flipped downward to pour out the mixed colored permeable concrete. This prevents water in the mixture from flowing out of the mixing tank, ensuring that the water ratio in the molded colored permeable concrete meets the preparation requirements and improving the quality of the prepared concrete.

Detailed Implementation

[0023] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0024] Please see Figures 1 to 7A high-efficiency preparation and molding device for colored permeable concrete includes a mixing frame 1 and a mixing tank 2 installed on the mixing frame 1. A mixing motor 3 is installed on the mixing frame 1. Both ends of the mixing tank 2 are rotatably connected to the mixing frame 1 through a rotating shaft. The output shaft of the mixing motor 3 passes through the rotating shaft and the mixing tank 2 and is fixedly connected to the mixing rod inside the mixing tank 2. A material outlet 201 is opened through the top of the mixing tank 2. A sealing plate 4 is connected to the outside of the material outlet 201. A tilting motor 5 is fixedly connected to the side of the mixing frame 1 away from the mixing motor 3. The output shaft of the tilting motor 5 passes through the mixing frame 1 and is fixedly connected to the rotating shaft at the end of the mixing tank 2.

[0025] like Figures 1 to 7 As shown, the high-efficiency preparation and molding device for colored permeable concrete in this utility model is structurally similar to existing high-efficiency preparation and molding devices for colored permeable concrete. For example, patent publication number CN214982021U discloses a forced mortar mixer. The main improvement of this utility model is to avoid moisture loss in the mixing tank 2, thereby improving the quality of the prepared concrete. Figures 1 to 7 As shown, the high-efficiency preparation and molding device for colored permeable concrete of this utility model is used by first starting the tilting motor 5 to rotate the mixing tank 2 on the mixing frame 1 so that the material outlet 201 faces upward. At this time, various raw materials for preparing colored permeable concrete can be added into the mixing tank 2 through the material outlet 201. Then, the stirring motor 3 is started to drive the stirring rod inside the mixing tank 2 to stir and mix. During this process, since the material outlet 201 is at the top, the water used for mixing will not be lost in the mixing tank 2, ensuring that the water ratio in the mixing tank 2 meets the preparation requirements and improving the quality of the colored permeable concrete. After the colored permeable concrete is mixed, the stirring motor 3 is stopped, and the tilting motor 5 drives the mixing tank 2 to rotate so that the material outlet 201 is rotated downward, so that the colored permeable concrete prepared inside the mixing tank 2 can be poured out from the material outlet 201. During the stirring, the sealing plate 4 can be used to seal the material outlet 201 located at the top to prevent the raw materials inside the mixing tank 2 from splashing during the stirring process.

[0026] like Figures 1 to 5 As shown, the tilting motor 5 is a locking motor. Using a locking motor as the tilting motor 5 ensures that the mixing drum 2 will not tilt along with the mixing motor 3 and the concrete being mixed inside during mixing, thus improving the stability of the mixing drum 2.

[0027] like Figures 1 to 5As shown, two fixing blocks 6 are fixedly connected to both ends of the outer surface of the mixing tank 2. A limiting rod 7 is fixedly connected between the two fixing blocks 6 at the same end. Limiting holes 401 are opened at both ends of the sealing plate 4. The two limiting rods 7 are slidably connected to the two limiting holes 401 respectively. A compression spring 8 is sleeved on the outside of the two limiting rods 7. One end of the two compression springs 8 is fixedly connected to the two ends of the sealing plate 4 on the same side. The other end of the two compression springs 8 is fixedly connected to the adjacent fixing block 6 respectively. The two limiting rods 7 ensure that the sealing plate 4 is connected to the outside of the mixing tank 2, and the compression springs 8 can push the sealing plate 4 upward, so that the sealing plate 4 can stably seal the material outlet 201 during the preparation and mixing of colored permeable concrete.

[0028] like Figure 3 and Figure 4 As shown, a stop bar 9 is fixedly connected to the side of the mixing frame 1 away from the compression spring 8. The stop bar 9 is located below the mixing tank 2. A compression rod 10 is fixedly connected to the end of the sealing plate 4 away from the compression spring 8 and the side away from the mixing tank 2. The compression rod 10 abuts against the stop bar 9. When the tilting motor 5 drives the mixing tank 2 to tilt downwards, the compression rod 10 at the end of the sealing plate 4 will first contact the stop bar 9. The fixed stop bar 9 will block the compression rod 10 and the sealing plate 4. As the mixing tank 2 continues to tilt downwards, the position of the sealing plate 4 remains unchanged and compresses the compression spring 8, thereby tilting the material outlet 201 of the mixing tank 2 downwards to allow the colored permeable concrete prepared inside the mixing tank 2 to be automatically poured out from the material outlet 201 without the need for manual opening of the sealing plate 4, facilitating the unloading operation.

[0029] like Figures 1 to 7 As shown, two symmetrically arranged connecting blocks 11 are fixedly connected to the middle position of the sealing plate 4 near the compression spring 8. Each of the two connecting blocks 11 has a flip hole 101 on an adjacent side. A hook 12 is connected between the two connecting blocks 11. A connecting shaft 13 is fixedly connected to both sides of one end of the hook 12. The two connecting shafts 13 are rotatably connected to the two flip holes 101 respectively. A hook block 14 is fixedly connected to the outer wall of the mixing tank 2. The hook block 14 is matched with the hook 12. When the mixing tank 2 is tilted downwards for unloading, the hook 12 can be hooked onto the hook block 14 on the outside of the mixing tank 2. After unloading, when the mixing tank 2 is tilted upwards again by the tilting motor 5, the hook 12 hooked onto the hook block 14 can prevent the compression spring 8 from squeezing the sealing plate 4 back into place, thus keeping the material outlet 201 exposed, making it convenient to add raw materials into the mixing tank 2 again. When mixing, the hook 12 can be manually pushed outwards to disengage from the hook block 14, and the compression spring 8 can automatically squeeze the sealing plate 4 upwards to return it to its original position, thereby sealing the material outlet 201 of the mixing tank 2 during the mixing operation.

[0030] like Figure 6 and Figure 7 As shown, a spring groove 102 is provided on the inner wall of the flip hole 101. A torsion spring 15 is connected inside the spring groove 102. The torsion spring 15 is sleeved on the connecting shaft 13. One end of the torsion spring 15 is fixedly connected to the spring groove 102, and the other end is fixedly connected to the connecting shaft 13. The torsion spring 15 can keep the hook 12 pressed against the outer wall of the mixing tank 2, thereby preventing the hook 12 hooked on the hook block 14 from falling off.

[0031] like Figure 6 and Figure 7 As shown, the hook 12 has an inclined surface at the end away from the connecting block 11 and at the side closer to the mixing tank 2. With the inclined surface at the end of the hook 12, when the mixing tank 2 is tilted down to unload material, the hook 12 can automatically hook onto the hook block 14 through the contact and compression between the inclined surface of the hook 12 and the hook block 14, thus completing the limiting of the sealing plate 4.

[0032] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention.
