Description

Technical Field

[0001] This utility model belongs to the field of concrete processing technology, specifically relating to a permeable concrete preparation mixer. Background Technology

[0002] Permeable concrete, as an eco-friendly building material, is widely used in sponge city construction, eco-friendly parking lots, and sidewalks due to its excellent permeability and environmental protection characteristics. However, the preparation process of permeable concrete has high requirements for the mixing technology. Traditional mixing equipment has certain limitations in terms of mixing efficiency, discharge cleanliness, and maintenance convenience. At present, common permeable concrete mixing equipment mainly adopts fixed mixing tanks or forced mixers. After the fixed mixing tank is completed, manual assistance is usually required for discharge, which is not only inefficient but also prone to material residue, affecting the accuracy of subsequent proportioning. Therefore, a permeable concrete preparation mixer is needed to solve the above problems. Utility Model Content

[0003] The purpose of this utility model is to provide a permeable concrete mixing machine, which uses a hydraulic cylinder to move a square plate, which in turn moves a toothed plate. The toothed plate, through several protruding teeth, rotates the mixing tank to adjust the tilt angle of the mixing tank, thereby facilitating material feeding and discharging, as well as cleaning the inside of the mixing tank.

[0004] To achieve the above-mentioned technical objectives, the technical solution adopted by this utility model is as follows:

[0005] A permeable concrete mixing device includes a movable base and a mixing tank. The mixing tank is rotatably mounted on the upper side of the movable base. The lower side of the mixing tank is machined into a hemispherical shape. The upper side of the movable base has a placement groove that matches the mixing tank. The lower side of the mixing tank is fixedly provided with a plurality of circumferentially distributed protruding teeth. The upper side of the movable base has an elongated groove that communicates with the placement groove. A toothed plate that matches the elongated groove is slidably mounted on the upper side of the movable base. The toothed plate meshes with the plurality of protruding teeth. The interior of the movable base has a square cavity that communicates with the elongated groove. A square plate that matches the square cavity is fixedly provided on the side of the toothed plate near the square cavity. The interior of the movable base has two elongated cavities that communicate with the square cavities. The interior of the movable base has two hydraulic cylinders that match the elongated cavities. The output ends of the hydraulic cylinders are fixedly connected to the square plates. The mixing tank is provided with a mixing assembly.

Detailed Implementation

[0019] To enable those skilled in the art to better understand this utility model, the technical solution of this utility model will be further described below in conjunction with the accompanying drawings and embodiments.

[0020] like Figure 1-4 As shown, this utility model discloses a permeable concrete mixing device, including a movable base 1 and a mixing tank 10. The mixing tank 10 is rotatably mounted on the upper side of the movable base 1. The lower side of the mixing tank 10 is machined into a hemispherical shape. The upper side of the movable base 1 is provided with a placement groove 11 that matches the mixing tank 10. The lower side of the mixing tank 10 is fixedly provided with a plurality of circumferentially distributed protruding teeth 12. The upper side of the movable base 1 is provided with a long groove that communicates with the placement groove 11. The upper side of the movable base 1 is slidably fitted with a toothed plate 13 that matches the long groove. The toothed plate 13 meshes with the plurality of protruding teeth 12. The movable base 1 has a square cavity 14 that communicates with the long groove. The toothed plate 13 is fixedly provided with a square plate 15 that matches the square cavity 14 on the side near the square cavity 14. The movable base 1 has two long cavities that communicate with the square cavity 15. The movable base 1 has two hydraulic cylinders 16 that match the long cavities. The output ends of the hydraulic cylinders 16 are fixedly connected to the square plate 15. The mixing tank 10 is provided with a mixing assembly.

[0021] The mixing assembly includes a main shaft 20 rotatably mounted inside the mixing tank 10, a mixing motor 21 mounted on the upper side of the mixing tank 10, the output shaft of the mixing motor 21 being connected to the main shaft 20 for transmission, and a number of linearly distributed mixing blades 22 fixed on the side wall of the main shaft 20.

[0022] The mixing tank 10 is equipped with several circumferentially distributed scrapers 25, and several spirally distributed connecting rods 26 are fixed between the scrapers 25 and the main shaft 20.

[0023] When using this utility model, the user first activates the two hydraulic cylinders 16, causing the output ends of the two hydraulic cylinders 16 to extend and drive the square plate 15 to move. The square plate 15 drives the toothed plate 13 to move, and the toothed plate 13 engages with the protruding teeth 12 on the lower side of the mixing tank 10, thereby driving the mixing tank 10 to rotate, which facilitates the filling of the mixing tank 10. When it is necessary to discharge the mixing tank 10, the hydraulic cylinders 16 and the toothed plate 13 are used to make the mixing tank 10 continue to tilt to the right, which facilitates rapid discharge. After the mixing tank 10 has finished discharging, the hydraulic cylinders 16 and the toothed plate 13 are used to make the mixing tank 10 horizontal, which makes it easier for the user to clean the inside of the mixing tank 10 and improves the ease of use of this device.

[0024] When this utility model is in use and requires stirring or cleaning of the inside of the mixing tank 10, the user can directly start the stirring motor 21. The stirring motor 21 synchronously drives the main shaft 20 to rotate, and the main shaft 20 synchronously drives the stirring blades 22 to rotate, stirring the concrete material inside the mixing tank 10. At the same time, the main shaft 20 drives the scraper 25 to rotate through the connecting rod 26, scraping and cleaning the inside of the mixing tank 10 to prevent concrete residue from remaining on the inner wall of the mixing tank 10 and to ensure the accuracy of the concrete material ratio for each batch.

[0025] Furthermore, the user can transport concrete to a designated location via the mobile base 1, eliminating the need for concrete transfer and improving construction efficiency.

[0026] Furthermore, when this utility model is not in use, the mixing tank 10 can be laid flat to reduce the volume of the device and facilitate transportation.

[0027] This invention uses a hydraulic cylinder to move a square plate, which in turn moves a toothed plate. The toothed plate, through several protruding teeth, rotates the mixing tank to adjust its tilt angle, thereby facilitating feeding and discharging of materials and cleaning the inside of the mixing tank.

[0028] Vertical plates 30 are fixedly installed on both the front and rear side walls of the mixing tank 10. Two horizontal grooves 31 matching the vertical plates 30 are opened on the upper side of the movable base 1. Several linearly distributed hydraulic rods 32 matching the vertical plates 30 are installed on the upper side of the movable base 1. The vertical force during the rotation of the mixing tank 10 is distributed, the force on the protruding teeth 12 and the toothed plate 13 is reduced, and the service life of the device is extended.

[0029] Several mixing blades 22 are all inclined; this facilitates the mixing of concrete materials.

[0030] The lower interior of the mixing tank 10 is machined into an arc shape, and the scraper 25 matches the interior of the mixing tank 10; this prevents concrete residue from remaining inside the mixing tank 10 and ensures complete discharge of material from the mixing tank 10.

[0031] The above embodiments are merely illustrative of the principles and effects of this utility model and are not intended to limit the scope of this utility model. Any person skilled in the art can modify or alter the above embodiments without departing from the spirit and scope of this utility model. Therefore, all equivalent modifications or alterations made by those skilled in the art without departing from the spirit and technical concept disclosed in this utility model should still be covered by the claims of this utility model.
