[0024] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0025] like Figure 1-4As shown, a cement raw material mixing device includes a mixing device body 1; a first servo motor 11 is mounted on the top of the mixing device body 1; a mixing shaft 14 is fixedly connected to the output end of the first servo motor 11; the mixing shaft 14 is rotatably connected inside the mixing device body 1; an internal gear ring 13 is rotatably connected to the top inner side of the mixing device body 1; a rotating gear 15 is rotatably connected to the top inner side of the mixing device body 1; the rotating gear 15 is meshed inside the internal gear ring 13; teeth 18 are fixedly connected to the outer side of the mixing shaft 14 near the rotating gear 15; the rotating gear 15 is meshed on the outer side of the teeth 18; a crushing device body 16 is fixedly connected to the bottom outer side of the internal gear ring 13; a large-aperture filter plate 12 is fixedly connected to the inner side of the mixing device body 1 near the crushing device body 16; a valve body 17 is installed at the bottom inner side of the mixing device body 1; during operation, the first servo motor 11 is first driven to start working, driving the mixing shaft 14 in the mixing device... The main body 1 rotates internally, and the rotating stirring shaft 14 drives the teeth 18 and the rotating gear 15 to rotate, causing the internal gear ring 13 meshing with the rotating gear 15 to rotate in the opposite direction to the stirring shaft 14. This drives the main body 16 of the crushing device to rotate on top of the large-aperture filter plate 12. At this time, the raw materials are put into the main body 1 of the mixing device. The large-aperture filter plate 12 will intercept the larger cement pieces. Then, the main body 16 of the crushing device will squeeze and break up the lumps, and then the material will fall into the main body 1 of the mixing device. After the mixing is completed, the valve body 17 will be activated to discharge the material. In this step of mixing the cement raw materials, due to the long-term storage of cement, lumps may occur, resulting in uneven mixing of cement and affecting the strength of concrete. Therefore, the main body 16 of the crushing device blocks the larger cement lumps and then breaks them up, reducing the impact of cement lumps on the mixing effect, increasing the uniformity of cement raw material mixing, and reducing the impact on concrete strength.
[0026] like Figure 1-2 , Figure 5 As shown, the bottom of the mixing device body 1 is fixedly connected to a base 2; the top of the base 2 is provided with a threaded cylinder 21; a threaded column 22 is threadedly connected inside the threaded cylinder 21; a ball bearing 23 is rotatably connected to the bottom of the threaded column 22; during operation, the base 2 is placed on a flat surface, and then the threaded column 22 is rotated, causing the threaded column 22 to descend inside the threaded cylinder 21, and the ball bearing 23 contacts the ground. The four sets of threaded columns 22 support the threaded column 22 off the ground, which allows the mixing device body 1 to be moved. When the device needs to work, the ball bearing 23 is retracted into the base 2, increasing the stability of the device during operation. This step may require changing the position of the device when mixing cement, so the use of the ball bearing 23 can increase the convenience of moving the device. At the same time, the base 2 has a large contact surface with the ground, further increasing the stability of the device during operation.
[0027] like Figure 2, Figure 4 As shown, a fixing ring 3 is fixedly connected to the outside of the stirring shaft 14 near the bottom of the large-pore filter plate 12; a spring striking block 31 is fixedly connected to the top of the fixing ring 3; and a vibrating block 32 is fixedly connected to the bottom of the large-pore filter plate 12. During operation, the fixing ring 3 rotates with the stirring shaft 14 at the bottom of the large-pore filter plate 12. The spring striking block 31 at the top of the fixing ring 3 continuously strikes the vibrating block 32 at the bottom of the large-pore filter plate 12, causing the large-pore filter plate 12 to vibrate. In this step, when the large-pore filter plate 12 blocks the clumped cement, the vibrating block 32 continuously vibrates the large-pore filter plate 12, increasing the cement throughput above the large-pore filter plate 12 and increasing the working efficiency of the large-pore filter plate 12.
[0028] like Figure 1-2 As shown, a discharge cylinder 41 is installed at the bottom of the mixing device body 1 near the valve body 17; a second servo motor 4 is fixedly connected to one end of the outer side of the discharge cylinder 41; a conveying roller 42 is fixedly connected to the output end of the second servo motor 4; the conveying roller 42 rotates inside the discharge cylinder 41; during operation, when the valve body 17 opens the mixing device body 1, the mixed cement flows into the discharge cylinder 41, and then the second servo motor 4 drives the conveying roller 42 to rotate inside the discharge cylinder 41, sending out the mixed cement. In this step, when discharging cement from the mixing device body 1, the discharge speed may not be uniform enough, resulting in insufficient or excessive cement during use. Therefore, the discharge speed is controlled by the rotation of the conveying roller 42, reducing the occurrence of excessive or insufficient cement during use due to uneven cement discharge.
[0029] like Figure 2 , Figure 4 As shown, a limiting ring 5 is rotatably connected to the outside of the stirring shaft 14 near the main body 16 of the crushing device; a limiting strip 51 is fixedly connected to one end of the main body 16 of the crushing device near the limiting ring 5; the limiting strip 51 is slidably connected inside the limiting ring 5; during operation, the limiting strip 51 is inserted into the limiting ring 5 to connect the main body 16 of the crushing device to the stirring shaft 14. In the process of crushing lumpy cement by the main body 16 of the crushing device, long-term use may cause the main body 16 of the crushing device to shift. Therefore, the limiting ring 5 limits the main body 16 of the crushing device, reducing the possibility of the main body 16 of the crushing device shifting due to long-term use.
[0030] like Figure 1-2 As shown, a support block 6 is fixedly connected to the top of the base 2; a discharge cylinder 41 is placed on the top of the support block 6; during operation, when the discharge cylinder 41 discharges material, the support block 6 supports one end of the discharge cylinder 41, reducing the possibility of deformation of the discharge cylinder 41 due to gravity during long-term use.
[0031] like Figure 1-2 , Figure 5As shown, a reinforcing pad 7 is fixed to the top of the threaded cylinder 21. During operation, the reinforcing pad 7 is placed on the top of the threaded cylinder 21, which increases the friction between the threaded column 22 and the threaded cylinder 21 and reduces the possibility of the threaded column 22 becoming loose during use.
[0032] Working principle: First, the first servo motor 11 starts working, driving the stirring shaft 14 to rotate inside the main body 1 of the mixing device. The rotation of the stirring shaft 14 drives the gear 18 and the rotating gear 15 to rotate, causing the internal gear ring 13 meshing with the rotating gear 15 to rotate in the opposite direction to the stirring shaft 14, driving the main body 16 of the crushing device to rotate on top of the large-aperture filter plate 12. At this time, the raw material is put into the main body 1 of the mixing device. The large-aperture filter plate 12 will intercept larger cement particles. Then, the main body 16 of the crushing device will squeeze and break up the clumps, which will then fall into the main body 1 of the mixing device. After the mixing is completed, the valve body 17 is activated to discharge the material. During this step of mixing the cement raw material, due to the long-term storage of cement, clumping may occur, leading to… The cement mixture is not uniform enough, affecting the strength of the concrete. Therefore, the main body 16 of the crushing device blocks larger cement lumps and then breaks them up, reducing the impact of cement lumps on the mixing effect, increasing the uniformity of cement raw material mixing, and reducing the impact on concrete strength. The base 2 is placed on the ground, and then the threaded column 22 is rotated, causing the threaded column 22 to descend inside the threaded cylinder 21, and the ball bearings 23 contact the ground. The four sets of threaded columns 22 support the threaded column 22 off the ground, which allows the mixing device body 1 to be moved. When the device needs to work, the ball bearings 23 are retracted into the base 2 to increase the stability of the device during operation. This step may require changing the position of the device when mixing cement again. Therefore, the use of ball bearing 23 increases the ease of moving the device. Simultaneously, the larger contact area between the base 2 and the ground further enhances the stability of the device during operation. The fixing ring 3 rotates at the bottom of the large-pore filter plate 12 following the stirring shaft 14. The spring striking block 31 at the top of the fixing ring 3 continuously strikes the vibrating block 32 at the bottom of the large-pore filter plate 12, causing the large-pore filter plate 12 to vibrate. During this step, when the large-pore filter plate 12 blocks the clumped cement, the vibrating block 32 continuously vibrates the large-pore filter plate 12, increasing the cement throughput above the large-pore filter plate 12 and increasing its working efficiency. When the valve body 17 opens the mixing device body 1, the mixed cement flows into the discharge cylinder 41. The second servo motor 4 drives the conveying roller 42 to rotate inside the discharge cylinder 41, discharging the mixed cement. During this step, the cement may be discharged unevenly from the mixing device body 1, potentially leading to insufficient or excessive cement during use. Therefore, the rotation of the conveying roller 42 controls the discharge speed, reducing the occurrence of insufficient or excessive cement due to uneven discharge. The limiting strip 51 is inserted into the limiting ring 5, connecting the crushing device body 16 to the mixing shaft 14. During the crushing of lumpy cement by the crushing device body 16, long-term use may cause the crushing device body 16 to shift. Therefore, the limiting ring 5 limits the movement of the crushing device body 16.To reduce the risk of displacement of the main body 16 of the crushing device due to long-term use, a limiting strip 51 is inserted into the limiting ring 5 to connect the main body 16 of the crushing device to the stirring shaft 14. This step is necessary because the main body 16 of the crushing device may shift over time during the crushing of lumpy cement. The limiting ring 5 limits the main body 16 of the crushing device, reducing the risk of displacement. A reinforcing pad 7 is placed on top of the threaded cylinder 21, increasing the friction between the threaded column 22 and the threaded cylinder 21, reducing the possibility of loosening of the threaded column 22 during use.
