Description

Technical Field

[0001] The utility model relates to the technical field of recycled concrete mixing, in particular to a recycled concrete mixer with evenly dispersed crack-resistant fibers. Background Art

[0002] Adding crack-resistant fibers to recycled concrete is a technique for improving the performance of building materials. By incorporating an appropriate amount of these fibers into recycled concrete, the concrete's crack resistance and durability can be effectively enhanced. These fibers disperse stress concentrations within the concrete, reducing the initiation and propagation of cracks. They also increase the concrete's tensile strength and toughness, making it less susceptible to brittle failure when subjected to external forces.

[0003] According to announcement number CN220482128U, a device for adding uniformly dispersed anti-cracking fibers to concrete includes a concrete mixing chamber and a feeding chamber installed at the upper end of the concrete mixing chamber. A material guide trough is installed at one end of the outer wall of the feeding chamber. A support platform that can rotate horizontally along its inner wall is provided on the inner side of the feeding chamber. A discharge platform with a surface inclined to both sides is installed on the upper end of the support platform. A back plate is fixedly connected to the upper end of the support platform toward the center of the feeding chamber, and side baffles that can move longitudinally are provided on the left and right sides of the discharge platform.

[0004] In the above scheme, a mixing chamber is used to mix the recycled concrete, which still has the following disadvantages: since the mixing chamber is in the shape of a transparent upright cylinder, the area of ​​concrete available for observation is small. Therefore, when the staff add anti-cracking fibers for mixing, the small area available for observation may result in inaccurate information on the position of the added anti-cracking fibers, thereby reducing the uniformity of the mixing of the anti-cracking fibers and the recycled concrete. Utility Model Content

[0005] The purpose of the utility model is to provide a recycled concrete mixer with uniformly dispersed anti-cracking fibers, so as to solve the problem that the position information of added anti-cracking fibers may be inaccurate due to the small area available for observation, thereby reducing the uniformity of the mixing of anti-cracking fibers and recycled concrete.

[0006] In order to achieve the above-mentioned purpose of the utility model, the utility model adopts the following technical solutions: a recycled concrete mixer with uniformly dispersed crack-resistant fibers, comprising a supporting folding plate, a stirring pool rotatably arranged inside the supporting folding plate, a rotating hole being provided on one side of the stirring pool, a rotating rod being rotatably inserted inside the rotating hole, a plurality of stirring rings being provided on the rotating rod, a plurality of stirring rods being fixed on the inner wall surface of the stirring ring, one end of the stirring rod being fixed to the surface of the rotating rod, receiving grooves being respectively provided on the top surfaces of the two ends of the supporting folding plate, rotating columns being respectively fixed on both sides of the stirring pool, and the rotating columns and the receiving grooves being rotatably arranged.

[0007] Preferably, a fixed folding plate is fixed on one side of the stirring tank, a driving motor is fixed on one side of the fixed folding plate, the output shaft of the driving motor is rotatably inserted with the fixed folding plate, a main rotating wheel is fixed to one end of the output shaft of the driving motor, a secondary rotating wheel is fixed to one end of the rotating rod, a transmission belt is wrapped around the surface of the main rotating wheel, and the transmission belt is in contact with the surface of the secondary rotating wheel.

[0008] Preferably, the top surfaces of both ends of the supporting folding plate are detachably provided with loading and unloading plates, the bottom surface of the loading and unloading plate is provided with a splicing groove, the top surface of the loading and unloading plate is provided with two fixing holes, and the top surfaces of both ends of the supporting folding plate are respectively provided with two threaded grooves, and fixing bolts are rotatably inserted into the interior of the fixing holes, and the bottom end of the fixing bolt passes through the fixing hole and is threadedly connected to the threaded groove.

[0009] Preferably, a fixing groove is provided at one end of the rotating column, and the internal thread of the fixing groove is connected to the intercepting bolt.

[0010] Preferably, a limiting rod is fixed to the bottom surface of the stirring tank, and a limiting groove is provided on the inner bottom surface of the supporting folding plate, and the limiting rod and the limiting groove are slidably arranged.

[0011] Preferably, a first sliding rod is fixed to the inner top surface of the supporting folding plate, a limit plate is rotatably inserted on the first sliding rod, a limit folding plate is slidably provided on the inner bottom surface of the supporting folding plate, two second sliding rods are fixed to the inner bottom surface of the supporting folding plate, sliding tubes are respectively fixed on both sides of the limiting folding plate, and the second sliding rod and the sliding tube are slidably inserted.

[0012] Compared with the existing technology, the recycled concrete mixer with uniformly dispersed crack-resistant fibers using the above technical solution has the following beneficial effects:

[0013] 1. When the staff is stirring the recycled concrete inside the mixing tank, the drive motor is in working condition. When the drive motor is working, the rotating output shaft will drive the main impeller to rotate, and in the process of rotation, the transmission belt will be used to drive the secondary impeller to rotate synchronously, which can drive the rotating rod to rotate synchronously. The rotating rotating rod will drive the stirring ring and the stirring rod to rotate, and stir and mix the inside of the mixing tank thoroughly. At the same time, the staff will add anti-cracking fibers into the mixing tank when stirring the recycled concrete. Since the length of the mixing tank is long, the area where the recycled concrete can be observed can be increased when stirring the recycled concrete. The staff can add anti-cracking fibers at any time based on the observation results, thereby increasing the uniformity of the distribution of anti-cracking fibers inside the recycled concrete.

[0014] 2. When the mixing tank is damaged and needs to be replaced, the staff will first unscrew the fixing bolts from the inside of the threaded groove, and then remove the loading and unloading plate to separate the receiving groove and the splicing groove, so that the staff can disassemble and replace the damaged mixing tank. When the new mixing tank is fixed on the supporting folding plate, the rotating column is inside the receiving groove, and then the staff will screw the intercepting bolts into the inside of the fixing groove to prevent the rotating column from slipping out of the inside of the receiving groove. When the recycled concrete inside the mixing tank is mixed, the staff will push the mixing tank to make the mixing tank rotate with the rotating column as the center, so that the staff can pour out the recycled concrete inside the mixing tank.

[0015] 3. When the mixing tank is mixing recycled concrete, the staff will apply force to the limit plate, so that the limit plate rotates with the first sliding rod as the center and is intercepted on one side of the limit rod. Then the staff pushes the limit folding plate to slide horizontally. When sliding, the limit folding plate will drive the sliding tube to slide on the second sliding rod, and the limit plate will be set inside to fix the position of the limit plate on the bottom surface of the support folding plate, thereby preventing the limit rod from sliding inside the limit groove, thereby increasing the stability of the mixing tank when mixing recycled concrete.

[0023] During use, when the staff is stirring the recycled concrete inside the mixing tank 2, the drive motor 10 is in working condition. When the drive motor 10 is working, the rotating output shaft will drive the main impeller 11 to rotate, and in the process of rotation, the transmission belt 13 will be used to drive the secondary impeller 12 to rotate synchronously, which can drive the rotating rod 4 to rotate synchronously. The rotating rotating rod 4 will drive the stirring ring 5 and the stirring rod 6 to rotate, and stir and fully mix the inside of the mixing tank 2. At the same time, the staff will add anti-cracking fibers to the inside of the mixing tank 2 when stirring the recycled concrete. Since the length of the mixing tank 2 is long, the area where the recycled concrete can be observed can be increased when stirring the recycled concrete. The staff can replenish the anti-cracking fibers at any time based on the observation results, thereby increasing the uniformity of the distribution of the anti-cracking fibers inside the recycled concrete.
