DETAILED DESCRIPTION

[0020] The present invention will be further described below with reference to the accompanying drawings.

[0021] The directions mentioned in this specification are based on the directions of the foundation material mixing device for highway engineering of the present invention during normal operation, and do not limit the directions during storage and transportation. They only represent relative position relationships, not absolute position relationships.

[0022] Example 1:

[0023] like Figure 1 、 Figure 2 as well as Figure 3 As shown together, the foundation material mixing device for highway engineering includes a kettle body 1, a first driving component, and a stirring device, and the stirring device is located in the kettle body 1.

[0024] The stirring device includes a first cylinder 2, a second cylinder 3, a connecting plate 4, and a stirring shaft 5. The second cylinder 3 is located at the bottom of the kettle 1 and is arranged horizontally. The two ends of the second cylinder 3 are rotatably connected to the side wall of the kettle 1. The first cylinder 2 and the second cylinder 3 are arranged parallel to each other. The first cylinder 2 is located above the kettle 1. The top surface of the kettle 1 is an arc-shaped surface, and the first cylinder 2 is attached to the arc-shaped surface. The two ends of the stirring shaft 5 are rotatably connected to the second cylinder 3 and the first cylinder 2 respectively. The stirring shaft 5 is provided with a stirring blade 50.

[0025] The two ends of the connecting plate 4 are respectively fixed to the second cylinder 3 and the first cylinder 2. In this embodiment, there are two connecting plates 4, and the two connecting plates 4 are respectively close to the opposite sides of the kettle body 1. The first drive assembly drives the stirring device to rotate around the second cylinder 3. In this embodiment, the first drive assembly includes a first motor 20 fixed to the first cylinder 2. A first drive shaft 21 is connected to the first cylinder 2 for rotation. The main shaft of the first motor 20 is connected to the first drive shaft 21 through a coupling. The first motor 20 drives the first drive shaft 21 to rotate. Through the first drive shaft 21, a first gear 22 is coaxially fixed to the first drive shaft 21. An outer gear ring 11 is provided on the outside of the kettle body 1. The tooth surface of the outer gear ring 11 is set upward, and the first gear 22 is meshed with the outer gear ring 11. The gear is driven to rotate by the first drive shaft 21, so that the gear moves along the outer gear ring 11, that is, the left and right swing of the entire stirring device is achieved. This method has strong stability. In other methods, the left and right swing of the stirring device can also be achieved by directly driving the second cylinder 3 to rotate.

[0026] The second cylindrical body 3 is provided with the second driving assembly that drives the stirring shaft 5 to rotate.In the present embodiment, the second driving assembly includes the second motor 30 that is fixed on the second cylindrical body 3, and the second driving shaft 31 is connected with rotation in the second cylindrical body 3. The main shaft of the second motor 30 is connected with the second driving shaft 31 by a coupling. The second driving shaft 31 is coaxially fixed with the second gear 32, and the stirring shaft 5 is coaxially fixed with the third gear 51. The second gear 32 and the third gear 51 are both bevel gears, and the two are meshed. The second driving shaft 31 is driven to rotate by the second motor 30, and then the rotation of the stirring shaft 5 is realized under the transmission of two bevel gears. In other ways, the second motor 30 can also be cancelled, the first driving shaft 21 is connected with the second driving shaft 31 by sprocket-chain transmission, and the synchronous rotation of the first driving shaft 21 and the second driving shaft 31 is completed only by the first motor 20 drive.

[0027] When in use, the first motor 20 and the second motor 30 are started, and the first motor 20 controls the gear to rotate forward for a specific number of revolutions so that the second drive shaft 31 reaches the edge of the kettle body 1, and then controls the gear to rotate reversely for a specific number of revolutions so that the second drive shaft 31 is reset. This cycle is repeated. During this process, the stirring shaft 5 rotates continuously to achieve stirring of the raw materials, so that the raw materials are mixed more evenly and efficiently.

[0028] Furthermore, the top surface of the kettle body 1 is provided with an arcuate groove 10, which extends along the arcuate surface. The first cylinder body 2 is connected to a roller 23, which is connected in a rolling manner in the arcuate groove 10. When the first cylinder body 2 moves along the arcuate surface, the roller 23 moves synchronously in the arcuate groove 10, making the swing of the stirring device more stable.

[0029] Preferably, there are multiple stirring shafts 5, and the multiple stirring shafts 5 are arranged at intervals along the axial direction of the second cylinder 3. The multiple stirring shafts 5 are transmission-connected to the same second drive shaft 31. The rotation of the second drive shaft 31 can drive the multiple stirring shafts 5 to rotate synchronously, further improving the stirring efficiency.

[0030] Furthermore, scraping blades 40 are provided on both the left and right sides of the connecting plate 4. The blade ends of the scraping blades 40 are pressed against the inner wall of the kettle body 1. When the stirring device swings left and right, the scraping blades 40 on both sides of the connecting plate 4 will continuously scrape the inner wall of the kettle body 1. By scraping the raw materials on the inner wall of the kettle body 1 by the scraping blades 40, the raw materials on the inner wall of the kettle body 1 can be continuously involved in the raw material mixing, further improving the uniformity of the raw material mixing.

[0031] Example 2:

[0032] The difference between this embodiment and the first embodiment is that Figure 4 As shown, an annular cavity 24 is provided in the first cylinder 2. A water inlet 240 communicating with the annular cavity 24 is provided at the top of the first cylinder 2. The water inlet 240 is connected to a water pump via a hose, and the water pump draws water from a water source into the annular cavity 24. The bottom of the first cylinder 2 is provided with a plurality of water outlets 241 communicating with the annular cavity 24. The plurality of water outlets 241 are arranged at intervals along the axial direction of the first cylinder 2. After entering the annular cavity 24, the water is evenly sprayed into the kettle body 1 through the plurality of water outlets 241, achieving uniform water addition or uniform water inflow when the kettle body 1 is cleaned. In other methods, other liquid raw materials can also be added through this structure.

[0033] The present invention is not limited to the above-mentioned specific implementation methods. Various modifications made by ordinary technicians in this field based on the above-mentioned conception without creative work are all within the scope of protection of the present invention.
