Technical Field

[0001] This utility model relates to the field of mixer technology, and in particular to a dust-reducing cement mortar mixer. Background Technology

[0002] A cement mortar mixer is a type of construction machinery mainly used for mixing building materials such as cement, sand, gravel, and various dry powder mortars. It is a machine with a bladed shaft that rotates in a cylinder or trough to mix various raw materials into a mixture or a mixture of suitable consistency. Mixers are widely used on construction sites. However, when mixing raw materials such as cement mortar, the existing mixers are prone to generating a large amount of dust pollution during the feeding or mixing process due to the powdery structure of cement. Since the feeding port of the existing mixers is large, it is not easy to use dust collection fans to reduce dust. Therefore, there is room for improvement. An improvement plan is proposed here.

[0016] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this utility model, not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.

[0017] Please see Figure 1-5 An embodiment of this utility model is provided: a dust-reducing cement mortar mixer, including a mixing box 1, a feed inlet 11 at the top of the mixing box 1, a discharge pipe 19 installed on one side of the bottom of the mixing box 1, a mixing motor 2 installed at the bottom of the mixing box 1, and a rotating shaft 3 installed at one end of the mixing motor 2. One end of the rotating shaft 3 extends into the interior of the mixing box 1, and both ends of the rotating shaft 3 are fitted with connecting sleeves 4, and both sides of the connecting sleeves 4 are provided with detachable mechanisms 5. The detachable mechanism 5 includes a connecting block 501, which is installed on one side of the connecting sleeve 4. A limiting block 502 is installed inside the connecting block 501, and a connecting bolt 503 passes through between the limiting block 502 and the connecting block 501. An anti-slip pad 505 is fitted on one end of the connecting bolt 503, and anti-slip teeth 504 are evenly installed on the side of the anti-slip pad 505 near the connecting block 501. A connecting nut 506 is fitted on the outside of the connecting bolt 503 on the other side of the anti-slip pad 505. Specifically, such as Figure 1 and Figure 3 As shown, during use, the connecting bolt 503 and the connecting nut 506 are used to fix the limiting block 502. This fixing method is easy to disassemble. At the same time, the connecting block 501 is used to limit the limiting block 502, thereby realizing the installation of the first stirring fan blade 7. Meanwhile, the anti-slip teeth 504 and the anti-slip pad 505 make the installation of the connecting nut 506 more secure. The detachable mechanism 5 has first stirring blades 7 installed on both sides; The first stirring fan blade 7 is provided in two sets, and each set has four blades. The cross-section of the first stirring fan blade 7 is fan-shaped, and the first stirring fan blade 7 is set at an angle. Specifically, such as Figure 1 and Figure 4 As shown, the first stirring blade 7 is tilted during use to reduce the resistance it experiences during rotation and improve its service life. Stirring rods 6 are installed on both sides of the outside of the rotating shaft 3, and second stirring blades 17 are evenly installed on both sides of the stirring rods 6, and protrusions 18 are evenly installed on both sides of the second stirring blades 17. Multiple spikes 18 are provided, and the spikes 18 are symmetrically distributed about the vertical central axis of the second stirring blade 17, and the spikes 18 are evenly distributed on the second stirring blade 17. Specifically, such as Figure 1 and Figure 5 As shown, during use, the spikes 18 act to reduce the crushing effect on cement lumps that come into contact with the second mixing blade 17 during rotation, thereby improving the cement mixing effect. The feed inlet 11 is fitted with a support ring 20, and both sides of the top of the support ring 20 are provided with adjustment mechanisms 10. The adjustment mechanism 10 includes a support rod 1001, which is mounted on the top of the support ring 20. A rotating rod 1002 is mounted on the top of the support rod 1001, and a guide hole 1003 is provided inside the rotating rod 1002. A guide block 1004 is installed inside the guide hole 1003, and one side of the guide block 1004 is connected to the top of the lifting rod 16. Specifically, such as Figure 1 and Figure 2 As shown, during use, the guide block 1004 moves inside the guide hole 1003 by moving the lifting rod 16 up and down, so as to adjust the position of the second nozzle 12 by adjusting one side of the rotating rod 1002. A second nozzle 12 is installed on one side of the regulating mechanism 10, and a second guide pipe 13 is installed on one side of the second nozzle 12. A lifting rod 16 is installed at the bottom of the regulating mechanism 10, and the bottom of the lifting rod 16 passes through the support ring 20 and the top of the mixing tank 1. A first nozzle 8 is installed at the bottom of the lifting rod 16, and a first guide pipe 9 is installed on one side of the first nozzle 8. One end of the first guide pipe 9 and the second guide pipe 13 are connected to the external water supply pipe through a tee pipe. Specifically, such as Figure 1 As shown, when in use, water is sprayed to moisten the cement dust, which then falls under the influence of gravity, thus achieving the effect of dust suppression. The lifting rod 16 has evenly spaced positioning holes 15 on its exterior, and positioning pins 14 are connected between the positioning holes 15 and the support ring 20. The lifting rod 16 moves vertically under the action of the support ring 20 and the mixing tank 1, and the positioning holes 15 are evenly distributed on the lifting rod 16. Specifically, such as Figure 1 As shown, during use, the positioning hole 15 and positioning pin 14 are used to fix the lifting distance of the lifting rod 16, thereby realizing the position adjustment of the first nozzle 8 and the second nozzle 12, so as to achieve the dust suppression effect of dust at different angles.

[0018] Working principle: When using this utility model, firstly, the external water supply pipe is activated, allowing water to flow through the first guide pipe 9 and the second guide pipe 13, exiting from the first nozzle 8 and the second nozzle 12. Then, cement is poured into the mixing tank 1 through the feed inlet 11. During the pouring process, the water spraying action of the first nozzle 8 and the second nozzle 12 wets the cement dust, causing it to fall under gravity and reducing dust dispersion. After the cement is poured, the positioning pin 14 is pulled out, and the lifting rod 16 is moved upward, causing the guide block 1004 to slide inside the guide hole 1003. Subsequently, one side of the rotating rod 1002 is lifted upward, causing the second nozzle 12 to rotate downward. At the same time, the upward movement of the first nozzle 8 changes the spray direction of the water flow, making the second nozzle 12 more aligned with the inside of the feed inlet 11. This reduces the upward surge and leakage of dust during cement mixing, thereby improving the quality of the construction site environment. Secondly, start the mixing motor 2 to make the rotating shaft 3 rotate, which in turn makes the connecting sleeve 4 rotate, and the first mixing blade 7 rotates synchronously to achieve the mixing effect of cement and water. The rotation of the rotating shaft 3 makes the mixing rod 6 rotate synchronously, which in turn makes the second mixing blade 17 drive the spike 18 to rotate synchronously. Through the action of the spike 18, the second mixing blade 17 can break up the cement blocks during the stirring process, which helps to improve the fullness of the mixing. Finally, by screwing the connecting nut 506 to separate it from the connecting bolt 503, and then taking out the anti-slip pad 505 and the anti-slip teeth 504, the connecting bolt 503 can be disassembled, which makes it easier to take out the limiting block 502 from the connecting block 501, thereby disassembling the first stirring blade 7 and making it easier to replace the first stirring blade 7.
