[0020] It should be noted that, unless otherwise specified, the embodiments and features described in this application can be combined with each other. This application will now be described in detail with reference to the accompanying drawings and embodiments.

[0021] To enable those skilled in the art to better understand the present application, the technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present application, and not all embodiments. Based on the embodiments in the present application, all other embodiments obtained by those of ordinary skill in the art without creative effort should fall within the scope of protection of the present application.

[0022] like Figure 1 and 2 As shown, this application provides a concrete mixing device, including a mixing tank body 1, a drive chamber 6 fixedly connected to the top of the mixing tank body 1, and a drive assembly inside the drive chamber 6 for driving the device to perform mixing. The drive assembly includes a first rotary motor 4 installed on the top of the drive chamber 6. The main stirring shaft 20 is fixedly connected to the output end of the first rotary motor 4; The first gear 16 is fixedly connected to the top of the outer side of the main stirring shaft 20; A first slide groove 14 is formed on the inner wall of the drive compartment 6. A first slider 15 that matches it is slidably connected inside the first slide groove 14. A fixing block is fixedly connected to one side of the first slider 15. The second gear 17, which is rotatably connected to one side of the bottom of the fixed plate, meshes with the first gear 16; The second rack plate 38 is fixedly connected to the inner wall of the drive compartment 6, and the second rack plate 38 meshes with the second gear 17.

[0023] The bottom of the second gear 17 is fixedly connected to a secondary stirring shaft 21. Multiple sets of first blades are fixedly connected at equal intervals to the outer side of the main stirring shaft 20. Multiple sets of second blades are fixedly connected at equal intervals to the outer side of the secondary stirring shaft 21. A second dustproof plate 19 located below the first gear 16 is fixedly connected to the outer side of the main stirring shaft 20. A first dustproof plate 18 at the same level as the second dustproof plate 19 is fixedly connected to the inner wall of the drive chamber 6. The secondary stirring shaft 21 is located between the second dustproof plate 19 and the first dustproof plate 18.

[0024] In this embodiment, when the device starts stirring, the first rotary motor 4 is activated, causing the main stirring shaft 20 to start rotating and stirring. At the same time, the first gear 16 rotates, which drives the meshing second gear 17 to rotate. Since the second gear 17 is rotatably connected to the bottom of the fixed block on one side of the first slider 15, and the second gear 17 meshes with the second rack plate 38, the rotation of the first gear 16 will cause the second gear 17 to rotate on its own axis and rotate around the first gear 16 as the center. That is, when the main stirring shaft 20 starts stirring, the auxiliary stirring shaft 21 rotates around the main stirring shaft 20 and stirs at the same time. This design greatly improves the degree of disorder in the mixing of concrete by the device, making the mixed concrete more uniform. During the mixing process of the device, the first dustproof plate 18 and the second dustproof plate 19 can block most of the dust from entering the drive chamber 6, avoiding affecting the operation of the motor and gear transmission.

[0025] like Figure 1 , 2 As shown in Figure 3, the bottom of the mixing tank body 1 is provided with the connecting chamber 33. The bottom of the outer side of the mixing tank body 1 is fixedly connected with a third fixing frame 10. There are two sets of third fixing frames 10. The other ends of the two sets of third fixing frames 10 are fixedly connected to the two ends of the connecting chamber 33 respectively. The top of the mixing tank body 1 is rotatably connected with a first toothed plate 13. The bottom of the first toothed plate 13 is rotatably connected to the top of the connecting chamber 33. The inner side of the first toothed plate 13 is fixedly connected with a scraper 35 that fits against the inner wall of the mixing tank body 1. A scraper blade is fixedly connected to one side of the scraper 35. A third rotary motor 34 is installed on one side of the connecting chamber 33. A rotating plate is fixedly connected to the output end of the third rotary motor 34, and the rotating plate matches the inner cavity of the connecting chamber 33. The bottom of the connecting chamber 33 is fixedly connected to the discharge tank 11, which is connected to it. The outside of the mixing tank body 1 is fixedly connected to the main support 2. The bottom of the main support 2 is fixedly connected to the mounting plate 7. The second rotary motor 8 is installed inside the mounting plate 7. One end of the discharge tank 11 is rotatably connected to the rotating shaft 37. One end of the rotating shaft 37 is fixedly connected to the output end of the second rotary motor 8. One end of the rotating shaft 37 is fixedly connected to the spiral plate 36. The other end of the rotating shaft 37 is fixedly connected to the third gear 12 that meshes with the first rack plate 13. Multiple sets of second fixing frames 9 are fixedly connected to the outside of the discharge tank 11.

[0026] In this embodiment, after the device finishes mixing the concrete, the third rotary motor 34 is started to rotate the rotating plate, which allows the concrete to fall into the discharge tank 11 through the connecting chamber 33. Then, the second rotary motor 8 is started to rotate the spiral plate 36 to discharge the concrete inside. When the output end of the second rotary motor 8 drives the rotating shaft 37 to rotate, the third gear 12 can be rotated at the same time. The third gear 12 will rotate the meshing first rack plate 13. The rotation of the first rack plate 13 will cause the scraper 35 to rotate, that is, the device can scrape the remaining concrete on the inner wall while discharging the material.

[0027] like Figure 1 , 4 As shown in Figure 5, a feed inlet 3 is provided on the top of the outer side of the mixing tank body 1. A first fixing frame 5 is fixedly connected to the outer side of the main body support 2. A dust collection box 22 is fixedly connected to the top of the first fixing frame 5. One end of the dust collection box 22 is connected to the interior of the mixing tank body 1. A fan 23 is installed at the other end of the dust collection box 22. The top and bottom of the dust collection box 22 are provided with third slide grooves 28. The interior of the two sets of third slide grooves 28 is slidably connected with third sliders 29. A fixing plate 30 is fixedly connected to one side of the third slider 29. A dust collection bag 27 is installed on one side of the fixing plate 30. A locking block 26 is fixedly connected to one side of the dust collection box 22. A first inclined surface 39 is provided on one side of the locking block 26. A handle compartment 24 is fixedly connected to the other side of the fixing plate 30. A handle is fixedly connected to one side of the handle compartment 24. A second sliding groove 32 is provided inside the handle compartment 24. A matching second slider 25 is slidably connected inside the second sliding groove 32. A spring 31 is installed at one end inside the second sliding groove 32. The end of the spring 31 is fixedly connected to one end of the second slider 25. A second inclined surface 40 matching the first inclined surface 39 is provided at the other end of the second slider 25. There are two sets of second inclined surfaces 40.

[0028] In this embodiment, during the process of feeding concrete raw materials into the device and discharging concrete, the exhaust fan 23 is activated to suck up the dust into the dust collection bag 27 in the dust collection box 22. In the initial stage of concrete feeding, the wind speed of the exhaust fan 23 is reduced to prevent unmixed cement in the concrete from being blown away. After the concrete is mixed, the concrete and cement are thoroughly mixed and difficult to blow away. The wind speed of the exhaust fan 23 is increased to enhance the dust removal effect. After dust removal for a period of time, the handle is pulled, causing the second inclined surface 40 of the second slider 25 inside the handle compartment 24 to slide along the first inclined surface 39. At the same time, the spring 31 contracts, which moves the fixing plate 30 and the third slider 29 moves in the third slide groove 28. Then the dust collection bag 27 can be replaced. After replacement, the fixing plate 30 can be pushed back, causing the second slider 25 to move again and the spring 31 to contract again until the second inclined surface 40 is stuck to one side of the first inclined surface 39.

[0029] Working principle: When the device starts mixing, the first rotary motor 4 is activated, causing the main mixing shaft 20 to rotate and mix. Simultaneously, the first gear 16 rotates, driving the meshing second gear 17 to rotate. Since the second gear 17 is rotatably connected to the bottom of a fixed block on one side of the first slider 15, and meshes with the second rack plate 38, the rotation of the first gear 16 causes the second gear 17 to rotate on its own axis and around the first gear 16. That is, when the main mixing shaft 20 starts mixing, the auxiliary mixing shaft 21 simultaneously rotates around the main mixing shaft 20 and mixes. This design significantly improves the mixing efficiency of the concrete, resulting in more uniform concrete. During the mixing process, the first dustproof plate 18 and the second dustproof plate 19 prevent most dust from entering the drive chamber 6, avoiding interference with motor operation and gear transmission. The second rotary motor 8 is activated, causing the spiral plate 36 to rotate, dispersing internal dust. When the concrete is discharged, the output end of the second rotary motor 8 drives the rotating shaft 37 to rotate, which simultaneously rotates the third gear 12. The third gear 12 will rotate the meshing first rack plate 13. The rotation of the first rack plate 13 will cause the scraper 35 to rotate. That is, while the device is discharging the material, it can scrape the concrete on the remaining inner wall. During the process of feeding concrete raw materials into the device and discharging concrete, the exhaust fan 23 is started to suck up the dust into the dust collection bag 27 in the dust collection box 22. After dust collection for a period of time, the handle is pulled, so that the second inclined surface 40 of the second slider 25 inside the handle compartment 24 slides along the first inclined surface 39. At the same time, the spring 31 contracts, which can move the fixing plate 30 and the third slider 29 moves in the third slide groove 28. Then the dust collection bag 27 can be replaced. After replacement, the fixing plate 30 can be pushed back, so that the second slider 25 moves again and the spring 31 contracts again until the second inclined surface 40 is stuck to one side of the first inclined surface 39.

[0030] The above description is merely a preferred embodiment of this application and is not intended to limit this application. Various modifications and variations can be made to this application by those skilled in the art. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this application should be included within the protection scope of this application.
