Description

Technical Field

[0001] The utility model relates to the technical field of cemented sand and gravel processing, in particular to a mixing device for cemented sand and gravel materials. Background Art

[0002] Cemented sand and gravel is a new type of composite material and a new material for dam construction. It is a mixture of sand and gravel, mixed with cement, fly ash and other cementitious materials. The mechanical properties of this material are between those of rockfill and concrete. It has higher strength than rockfill but lower strength than concrete. Cemented sand and gravel material has a small amount of cement, small hydration heat and low temperature effect, so the temperature rise will be much smaller than that of concrete dam.

[0003] The patent with the existing authorization announcement number "CN219563685U" discloses a mixing equipment for cemented sand and gravel materials, comprising a base, a tank body and a limiting mechanism, the tank body is rotatably mounted on the base through the limiting mechanism, and is transmission-connected to a driving mechanism, a fixing ring is fixedly mounted on the base at the rear side of the tank body, and the fixing ring is coaxially arranged with the tank body; an internal gear ring is mounted in the fixing ring; a plurality of second gears are rotatably mounted on the rear end surface of the tank body inside the internal gear ring, and the second gears are meshed with the internal gear ring; a plurality of stirring frames are arranged at intervals along the circumference of the interior of the tank body; the mixing equipment for cemented sand and gravel materials, through the coordinated arrangement of the fixing plate, the connecting ring, the fixing ring, the internal gear ring, the second gear and the stirring frame, enables the tank body and the stirring frame to rotate at differential speeds, thereby fully mixing the cemented sand and gravel materials, which is beneficial to improving the mixing efficiency and quality of the cemented sand and gravel;

[0004] However, there are the following deficiencies in this device:

[0005] 1. When processing cemented gravel materials, glue and other materials need to be fully mixed with the gravel. However, when the above device is used, the stirring effect of the gravel material is poor, resulting in a long time to fully mix the gravel material, which reduces the processing efficiency of the device;

[0006] 2. When mixing cemented sand and gravel materials, due to the viscosity of the glue, the material is very easy to adhere to the inner wall of the device. After the above device mixes the sand and gravel materials, it is difficult to automatically clean the inside of the device. Sand, gravel and other materials are easy to adhere to the inner wall of the device, affecting the subsequent mixing process and reducing the convenience of use of the device. Utility Model Content

[0025] A stirring rod 17 is sleeved on the middle part of the bottom of the fixed plate 6, and a gear B21 is provided on the top of the outer side of the stirring rod 17. A gear A20 meshing with the gear B21 is provided at the bottom of the rotating rod 7. A rotating ring 14 is rotatably connected to the edge of the bottom of the fixed plate 6, and an inner gear ring 19 meshing with the gear A20 is provided on the inner side of the rotating ring 14. Spoilers 15 are provided on both sides of the bottom of the rotating ring 14. A discharge pipe 18 is provided at the bottom of the mixing bin 2, and a discharge valve is provided on the inner side of the discharge pipe 18 for controlling the opening and closing state of the discharge pipe 18 to facilitate discharge. A scraper assembly is provided on the top of the inner wall of the mixing bin 2.

[0026] Furthermore, the scraping assembly includes a slider 3, an annular chute 4, a mounting ring 5, a scraper 16, a tooth 22, a spring 23, a groove 24 and a block 25. An annular chute 4 is provided at the top of the inner wall of the mixing bin 2. Two groups of sliders 3 are slidably connected on the inner side of the annular chute 4. The two groups of sliders 3 are close to each other and are jointly provided with a mounting ring 5. Scrapers 16 are provided on both sides of the bottom of the mounting ring 5. Grooves 24 are provided at both ends of the inner side of the mounting ring 5. Blocks 25 are hinged on the inner sides of the two groups of grooves 24. Springs 23 connected to the grooves 24 are provided at one end of the two groups of blocks 25. Teeth 22 cooperating with the blocks 25 are provided at both ends of the rotating ring 14, which can automatically clean the inner wall of the mixing bin 2 after the material is mixed.

[0027] Furthermore, an annular groove is provided at the edge of the bottom of the fixed plate 6, and sliding blocks that slide in cooperation with the annular groove are provided on both sides of the top of the rotating ring 14. When the rotating ring 14 rotates, the sliding blocks can be driven to slide along the annular groove to guide the rotating ring 14.

[0028] Furthermore, U-shaped rods are provided on both sides of the spoiler 15 to enhance the spoiler effect of the spoiler 15 and improve the mixing efficiency of the materials.

[0029] Working principle: When mixing cemented sand and gravel materials, the motor 9 can be started to run, and the motor 9 can drive the rotating rod 7 to rotate, and then the rotating rod 7 can drive the bevel gear A8 to rotate, and the engagement of the bevel gear A8 and the bevel gear B10 can drive the spiral conveying rod 12 to rotate. When materials such as sand and gravel and glue are added to the spiral conveying cylinder 13 from two sets of feed hoppers 11 respectively, the spiral conveying rod 12 can continuously convey the materials to one side, and when the materials are conveyed in the spiral conveying cylinder 13, the rotation of the spiral conveying rod 12 can be used to pre-mix the materials, thereby reducing the subsequent mixing time;

[0030] After the premixing is completed, the material can be discharged from the discharge pipe into the mixing bin 2. At this time, the rotating rod 7 can drive the gear A20 to rotate, and then the gear A20 drives the gear B21 so that the stirring rod 17 can stir the material. At the same time, the gear A20 can also drive the inner gear ring 19 to make the rotating ring 14 rotate in the opposite direction of the stirring rod 17, thereby driving the two sets of spoilers 15 to stir the material, thereby improving the turbulence effect on the material and allowing the material to be mixed quickly.

[0031] After the material is mixed, the control gear A20 rotates in the opposite direction. At this time, the gear A20 can drive the rotating ring 14 to rotate clockwise. During rotation, the two sets of teeth 22 can be stuck in one side of the block 25, thereby driving the mounting ring 5 to rotate. The mounting ring 5 can drive the two sets of scrapers 16 to scrape the inner wall of the mixing bin 2, so as to scrape off the adhered material and facilitate the cleaning of the mixing bin 2. During the material mixing process, the rotating ring 14 rotates counterclockwise. At this time, the teeth 22 will not be engaged with the block 25. During rotation, the teeth 22 can push the block 25 to overcome the elastic force of the spring 23 and be retracted into the groove 24, thereby failing to drive the scraper 16 to rotate, thereby preventing the scraping resistance of the scraper 16 from affecting the mixing effect of the material.
