[0024] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0025] Specific examples are given below.

[0026] like Figure 1-4As shown, a concrete mixing device comprises a mixer body 1; a driving device 11 is installed in the middle of the mixer body 1; the driving device 11 is fixedly connected to the top of the mixer body 1; a reciprocating screw 13 is fixedly connected to the top of the output end of the driving device 11, and the reciprocating screw 13 is rotatably arranged in the middle of a support frame 12; a first slider 14 is threadedly connected to the middle of the reciprocating screw 13; a rotating member 15 is rotatably connected to the middle of the first slider 14; a limiting rod 16 is fixedly connected to the top of the first slider 14, and the limiting rod 16 is slidably arranged in the middle of the support frame 12; the driving device A plurality of blades 17 are fixedly connected to the middle of the output end 11; a stirring block 18 is slidably connected to the inner wall of the blade 17; a connecting frame 19 is hingedly connected to the top of the stirring block 18, and the other end of the connecting frame 19 is hingedly set with the rotating member 15; when working, the staff needs to install the mixer body 1 in the working area, and then pour the material to be stirred into the mixer body 1. At this time, the switch of the driving device 11 can be turned on, so that the output end of the driving device 11 rotates and cooperates with the plurality of blades 17 to stir the material. By setting a reciprocating screw 13 at the top output end of the driving device 11 , so that when the driving device 11 is working, it will synchronously drive the reciprocating screw 13 to rotate, and the first slider 14 can slide back and forth in the middle of the reciprocating screw 13 under the action of the rotation force and in cooperation with the limit rod 16, and when the rotating member 15 moves upward or downward, the inclination angle of the connecting frame 19 will be changed, and when the blade 17 moves under the action of the driving device 11, it will synchronously pull the rotating member 15 as a whole to rotate at the outer wall of the first slider 14, and the movement of the stirring block 18 can be adjusted according to the inclination range of the stirring block 18, and the inclined stirring block 18 can be coordinated with the inclined stirring block 18. The mixing block 18 repeatedly pushes the accumulated materials at the bottom of the mixer body 1, and mixes the materials with the help of the centrifugal force generated by the rotation. This step is combined with the mixing block 18 to improve the uniformity of the mixing of the materials, reduce the problem that when the mixer body 1 is in use, some materials are precipitated at the bottom wall of the mixer body 1, resulting in the difficulty of the rotating multiple sets of blades 17 to fully mix the materials, and improve the quality of the concrete after processing. The rotating reciprocating screw 13 can make the mixing block 18 move up and down at a uniform speed, further improving the stability of the concrete mixing.

[0027] like Figure 1-3As shown, the bottom of the support frame 12 is fixedly connected to a shell 2, and the shell 2 is arranged on the top of the blade 17; the middle of the limit rod 16 is fixedly connected to a connecting rod 21; the end of the connecting rod 21 is fixedly connected to a piston plate 22, and the piston plate 22 is slidably arranged on the inner wall of the shell 2; the bottom of the shell 2 is fixedly connected to an exhaust port 23, and the exhaust port 23 is connected to the shell 2; when working, by arranging a connecting rod 21 in the middle of the limit rod 16, when the limit rod 16 as a whole moves downward, it will synchronously drive the connecting rod 21 to move, and the moving piston plate 22 will contact the inner wall of the shell 2, and in the process of downward extrusion, the gas collected inside the shell 2 will be quickly exhausted from the exhaust port. The gas is discharged from the output end of the outlet 23, so that the gas will contact the concrete inside the mixer body 1 and the rotating blades 17. At the same time, when the limit rod 16 is reset to the upward position, the external gas can be absorbed on the inner wall of the shell 2 again, and this is repeated. This step, combined with the gas discharged from the end of the exhaust port 23, can improve the cleanliness of the middle part of the blade 17, and reduce the problem that when the staff pours cement into the mixer body 1, some dust accumulates on the surface of the blade 17, resulting in greater resistance when the subsequent mixing block 18 slides on the inner wall of the blade 17. At the same time, when the gas contacts the concrete, it can blow the concrete to deform, thereby further improving the uniformity of concrete processing.

[0028] like Figure 3 As shown, the exhaust port 23 has a connecting pipe 3 threadedly connected to the inner wall thereof; an expansion pipe 31 is fixedly connected to the bottom of the connecting pipe 3, and the connecting pipe 3 and the expansion pipe 31 are connected; a plurality of exhaust holes 32 are provided in the middle of the expansion pipe 31; during operation, a rotatable connecting pipe 3 is provided on the inner wall of the exhaust port 23, so that when the gas is discharged from the middle of the exhaust port 23, the staff can rotate the connecting pipe 3 to install the expansion pipe 31 as a whole on the end of the exhaust port 23, and at the same time, the working angle of the expansion pipe 31 can be changed by means of the thread, and the gas can be discharged evenly in conjunction with the plurality of exhaust holes 32. This step cooperates with the expansion pipe 31 to increase the downward blowing area of ​​the exhaust port 23, thereby increasing the cleaning area of ​​the blades 17, and the rotating connecting pipe 3 can increase the working flexibility of the expansion pipe 31, and at the same time can reduce the subsequent cleaning trouble of the surface of the expansion pipe 31 by the staff due to the difficulty in disassembling it.

[0029] like Figure 4-5As shown, two groups of springs 4 are fixedly connected to the inner wall of the blade 17; a second slider 41 is fixedly connected to the end of the spring 4; a first scraper 42 is fixedly connected to the end of the second slider 41, and the first scraper 42 is arranged in contact with the inner wall of the mixer body 1; when working, the spring 4 is arranged in the middle of the blade 17, so that the first scraper 42 will contact the inner wall of the mixer body 1, and when the blade 17 is rotating, the first scraper 42 will scrape off the sticky concrete attached to the inner wall of the mixer body 1. The spring 4 with elastic force can make the first scraper 42 adapt to different raised surfaces when working. This step cooperates with the first scraper 42 to improve the cleanliness of the inner wall of the mixer body 1, and reduce the problem that after the concrete inside the mixer body 1 is taken out, some concrete adhering to the inner wall of the mixer body 1 is not cleaned in time and becomes hard and difficult to be cleaned. The elastic force generated by the compression of the spring 4 can improve the tightness of the first scraper 42 in contact with the inner wall of the mixer body 1 during operation, thereby improving the accuracy of scraping the inner wall of the mixer body 1.

[0030] like Figure 3 As shown, a bracket 5 is fixedly connected to the top of the support frame 12; a second scraper 51 is fixedly connected to the end of the bracket 5, and the inner wall of the second scraper 51 is in contact with the middle of the connecting rod 21; during operation, by arranging the bracket 5 on the top of the support frame 12, when the connecting rod 21 moves downward or upward, the fixed bracket 5 will support the second scraper 51, so that the second scraper 51 cleans the surface of the connecting rod 21. This step cooperates with the second scraper 51 in contact with the connecting rod 21, which can reduce the problem that when the connecting rod 21 moves, some cement impurities follow the connecting rod 21 into the inner wall of the shell 2, making it difficult for subsequent staff to clean it.

[0031] like Figure 3 As shown, a collecting plate 6 is fixedly connected to the middle part of the second scraper 51, and the collecting plate 6 is arranged at the top of the shell 2; when working, through the setting of the collecting plate 6, when the connecting rod 21 is working, the collecting plate 6 will block some of the fallen cement blocks. This step reduces the problem that some cement blocks fall on the top of the piston plate 22, resulting in greater resistance when the piston plate 22 slides on the inner wall of the shell 2.

[0032] like Figure 4 As shown, a plurality of groups of cutters 7 are fixedly connected to the middle of the stirring block 18; when working, by arranging the cutter 7 in the middle of the stirring block 18, when the stirring block 18 moves, the cutter 7 will cut the agglomerated materials accumulated inside the mixer body 1. This step cooperates with the arranged cutter 7 to reduce the problem that some agglomerated materials are difficult to be separated by the stirring block 18, and further improves the uniformity of the mixer body 1 in stirring the concrete material.

[0033] Working principle: After the mixer body 1 is installed in the working area, the material to be mixed is poured into the mixer body 1. At this time, the switch of the driving device 11 can be turned on, so that the output end of the driving device 11 rotates and cooperates with multiple blades 17 to mix the material. A reciprocating screw 13 is arranged at the top output end of the driving device 11, so that when the driving device 11 is working, it will synchronously drive the reciprocating screw 13 to rotate, and the first slider 14 can slide back and forth up and down in the middle of the reciprocating screw 13 under the action of the rotating force and in cooperation with the limit rod 16, and when the rotating member 15 moves upward or downward, the inclination angle of the connecting frame 19 will be changed, and the blades 17 are in the driving device. When the rotating member 15 moves under the action of 11, it will synchronously pull the rotating member 15 as a whole to rotate at the outer wall of the first sliding block 14, and the movement of the stirring block 18 can be adjusted according to the tilted range of the stirring block 18, and the materials at the bottom of the accumulated stirring machine body 1 are repeatedly pushed in cooperation with the tilted stirring block 18, and the materials are stirred with the help of the centrifugal force generated by the rotation. By arranging a connecting rod 21 in the middle of the limiting rod 16, when the limiting rod 16 as a whole moves downward, it will synchronously drive the connecting rod 21 to move, and the moving piston plate 22 will contact the inner wall of the shell 2, and in the process of downward extrusion, the gas collected in the shell 2 will be quickly discharged from the output end of the exhaust port 23, so that The gas will contact the concrete inside the mixer body 1 and the rotating blades 17. At the same time, when the limit rod 16 is reset to the upward position, the external gas can be absorbed again at the inner wall of the shell 2, and this is repeated. By providing a rotatable connecting pipe 3 on the inner wall of the exhaust port 23, when the gas is discharged from the middle of the exhaust port 23, the staff can rotate the connecting pipe 3 to install the expansion pipe 31 as a whole on the end of the exhaust port 23. At the same time, the working angle of the expansion pipe 31 can be changed by means of the thread, and the gas can be evenly discharged in conjunction with the multiple exhaust holes 32. By providing a spring 4 in the middle of the blade 17, the first scraper 42 can contact the inner wall of the mixer body 1. At the same time, when the blade 17 is rotating, the first scraper 4 2 will scrape off the sticky concrete attached to the inner wall of the mixer body 1. The spring 4 with elastic force can make the first scraper 42 adapt to different raised surfaces when working. By arranging a bracket 5 on the top of the support frame 12, when the connecting rod 21 moves downward or upward, the fixed bracket 5 will support the second scraper 51, so that the second scraper 51 cleans the surface of the connecting rod 21. By arranging a collecting plate 6, when the connecting rod 21 is working, the collecting plate 6 will block some of the fallen cement blocks. By arranging a cutter 7 in the middle of the stirring block 18, when the stirring block 18 moves, the cutter 7 will cut the agglomerated materials accumulated inside the mixer body 1.
