DETAILED DESCRIPTION

[0025] See also Figure 1-Figure 7 A mixer for water conservancy and hydropower engineering construction includes a mixing barrel 2 and a supporting mechanism 1 arranged thereunder. The mixing barrel 2 includes a barrel body 201, and a mixing mechanism 3 is rotatably connected inside the barrel body 201:

[0026] Furthermore, the mixing mechanism 3 includes a stirring shaft 301 arranged at the inner center of the barrel body 201, and a first gear 304 is fixedly sleeved on the surface of the stirring shaft 301, and a plurality of second gears 305 are meshingly connected to the surface of the first gear 304, and a threaded rod 306 is fixedly connected to the inner walls of the plurality of second gears 305, and a mounting plate 307 is rotatably connected to the top and bottom of the threaded rod 306, one end of the mounting plate 307 is fixedly connected to the surface of the stirring shaft 301, and a threaded sleeve 308 is threadedly connected to the surface of the threaded rod 306, and a scraper 309 is fixedly connected to one side of the threaded sleeve 308, and a limit rod 310 is slidably connected to the inner wall of the scraper 309, and the limit rod 310 is fixedly arranged on the opposite side of the mounting plate 307.

[0027] The stirring shaft 301 is the core component of the mixing mechanism 3, which is located at the center of the barrel 201 and is driven to rotate by the second motor 303. The first gear 304 is fixedly sleeved on the surface of the stirring shaft 301. As the stirring shaft 301 rotates, the second gear 305 meshing therewith is driven to rotate. The second gear 305 meshes with the first gear 304. There can be multiple second gears 305 distributed around the stirring shaft 301. Through gear transmission, uniform stirring is ensured. The threaded rod 306 is fixed on the inner wall of the second gear 305. When the second gear 305 rotates, the threaded rod 306 also rotates. The threaded sleeve 308 is threadedly connected to the surface of the threaded rod 306. As the threaded rod 306 rotates, the threaded sleeve 308 will move up and down along the threaded rod 306. The scraper 309 is fixed on one side of the threaded sleeve 308. As the threaded sleeve 308 moves, the scraper 309 will also slide up and down along the inner wall of the barrel body 201 to remove adhered materials. The limiting rod 310 is fixed on the mounting plate 307, passes through the scraper 309, limits the moving direction of the scraper 309, ensures that it can only slide vertically along the inner wall of the barrel body 201, and at the same time ensures that the scraper 309 is in stable contact with the inner wall of the barrel body 201.

[0028] With the rotation of the stirring shaft 301, the scraper 309 can not only make a circular motion along the inner wall of the barrel 201, but also make a vertical reciprocating motion under the action of the threaded rod 306, so that the material on the inner wall of the barrel 201 can be more thoroughly removed, avoiding material residue, improving the mixing efficiency and the quality of concrete. At the same time, this design can also reduce the frequency of manual cleaning, reduce maintenance costs, and improve overall production efficiency.

[0029] Furthermore, a discharge pipe 202 is fixedly connected to the bottom of the barrel body 201, a barrel cover 203 is movably connected to the top of the barrel body 201, electric push rods 204 are fixedly connected to the left and right sides of the barrel body 201 surface, and the telescopic ends of the electric push rods 204 are fixedly connected to the bottom of the barrel cover 203.

[0030] The electric push rod 204 is fixed on the left and right sides of the surface of the barrel body 201, and its telescopic end is connected to the bottom of the barrel cover 203. When the electric push rod 204 is retracted, it will pull the barrel cover 203 upward to open; when the electric push rod 204 is extended, it will push the barrel cover 203 downward to close. Through the electric control system of the electric push rod 204, the barrel cover 203 can be opened and closed automatically without manual operation, which saves manpower and improves safety. Especially when handling heavy-loaded materials, the automated barrel cover 203 opening and closing mechanism can significantly reduce the labor intensity of operators.

[0031] Furthermore, a second motor 303 is fixedly connected to the center of the top of the barrel cover 203, and a stirring shaft 301 is fixedly connected to the output end of the second motor 303. The bottom of the stirring shaft 301 extends to the bottom of the barrel cover 203 and is rotatably connected thereto.

[0032] The second motor 303 fixedly connected to the center of the top of the barrel cover 203 is the power source of the entire stirring system. The output end of the second motor 303 is directly fixedly connected to the stirring shaft 301, which means that the rotation energy of the second motor 303 is directly transmitted to the stirring shaft 301, driving the stirring shaft 301 to rotate, thereby driving the mixing mechanism 3 in the mixer to mix the materials.

[0033] Furthermore, a plurality of stirring blades 302 are equidistantly sleeved on the surface of the stirring shaft 301 , and at least four stirring blades are arranged on the surface of each stirring blade 302 .

[0034] The stirring blades 302 evenly distributed on the stirring shaft 301 can form a multi-layer stirring area. The stirring range of each layer of blades covers different heights, ensuring that materials at different depths in the barrel 201 can be fully stirred. The multi-blade design can better adapt to materials of different viscosities and specific gravities. Whether it is fine powder with good fluidity or viscous concrete, the mixing effect can be optimized by adjusting the angle of the stirring blades 302 and the shape of the stirring blades.

[0035] Furthermore, the supporting mechanism 1 includes a positioning frame 101 fixedly arranged at the bottom of the barrel body 201 , and a plurality of positioning sleeves 102 are equidistantly arranged on the surface of the positioning frame 101 .

[0036] The positioning frame 101 is fixedly arranged at the bottom of the barrel 201 to form a solid base for bearing the weight of the entire mixer. The positioning sleeves 102 are equidistantly arranged on the surface of the positioning frame 101 and are usually fixed to the positioning frame 101 by welding or other means. The number and position distribution of the positioning sleeves 102 should ensure that the mixer has sufficient support points in all directions to avoid excessive force on a single point.

[0037] Furthermore, first rotating rods 103 are fixedly connected to the left and right sides of the positioning frame 101 , and a support frame 104 is rotatably connected to the surface of the first rotating rod 103 . The support frame 104 is disposed below the positioning frame 101 .

[0038] Through the coordinated action of the positioning frame 101, the first rotating rod 103 and the supporting frame 104, the supporting mechanism 1 of the mixer for water conservancy and hydropower engineering construction not only provides basic supporting functions, but also enhances the flexibility and adaptability of the equipment, ensuring the stable operation and safe operation of the mixer under complex construction conditions.

[0039] Furthermore, a first pulley 105 is fixedly sleeved on one end surface of the first rotating rod 103 , a second pulley 107 is provided below the first pulley 105 , and a first belt 106 is transmission-connected between the second pulley 107 and the first pulley 105 .

[0040] When the second pulley 107 rotates, the first pulley 105 is driven to rotate through the first belt 106, and then the rotational motion is converted into a change in the angle of the support frame 104 through the connection between the first rotating rod 103 and the support frame 104, thereby achieving adjustment of the support frame 104.

[0041] Furthermore, a second rotating rod 108 is fixedly connected to the inner wall of the second pulley 107, a third pulley 109 is rotatably connected to the surface of the second rotating rod 108, a support frame 104 is rotatably connected to the surface of the third pulley 109, a first motor 110 is fixedly connected to the top of the support frame 104, and a second belt 111 is transmission-connected between the output shaft of the first motor 110 and the second rotating rod 108.

[0042] When the first motor 110 is started, its output shaft drives the second rotating rod 108 to rotate through the second belt 111, and then the second rotating rod 108 is connected to the third pulley 109 to convert the rotational motion into the adjustment of the angle of the support frame 104. This process realizes the automatic angle adjustment from the first motor 110 to the support frame 104, improving the accuracy and efficiency of the operation.

[0043] The above are only preferred embodiments of the present invention and are not intended to limit the present invention. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
