[0020] 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.

[0021] Example: Refer to Figure 1-5A concrete mixer for road construction includes a mobile frame 1, an installation bracket 2 fixedly installed inside the mobile frame 1, a tilting discharge assembly on the surface of the mobile frame 1, a mixing tank 3 mounted on the top of the installation bracket 2 via the tilting discharge assembly, a concrete mixing assembly inside the mixing tank 3, a discharge pipe 27 fixedly installed on the left side of the mixing tank 3, and a lifting and opening assembly on the left side of the mixing tank 3. The tilting discharge assembly includes a lower hinge seat 4 and a fixed seat 9. The lower hinge seat 4 is fixedly installed inside the mobile frame 1, and a hinged assembly is provided inside the lower hinge seat 4. The lower mounting sleeve 5 has a hydraulic push rod 6 fixedly installed at its end. An upper mounting sleeve 7 is fixedly installed at the output end of the hydraulic push rod 6. An upper hinge seat 8 is hinged to the surface of the upper mounting sleeve 7 and is fixedly installed at the bottom of the mixing tank 3. A fixed seat 9 is fixedly installed at the top of the mounting bracket 2. A mounting shaft 10 is fixedly installed inside the fixed seat 9. A rotating block 11 is rotatably mounted on the surface of the mounting shaft 10 and is fixedly installed at the bottom of the mixing tank 3. The lifting and opening assembly includes a mounting plate 23 fixedly installed on the left side of the mixing tank 3. An electric push rod 24 is fixedly installed on the top of the mounting plate 23. An opening and closing plate 25 is fixedly installed at the output end of the push rod 24. The opening and closing plate 25 is slidably connected to the discharge pipe 27. A guide rod 26 is fixedly installed on the top of the opening and closing plate 25. The guide rod 26 is slidably installed inside the mounting plate 23. After the concrete is mixed, the electric push rod 24 drives the opening and closing plate 25 to move upward, and the guide rod 26 guides the opening and closing plate 25, so that the concrete is discharged from the mixing tank 3 through the discharge pipe 27. At the same time, the hydraulic push rod 6 pushes the mixing tank 3 through the upper mounting sleeve 7 and the upper hinge seat 8, causing the rotating block 11 to rotate on the surface of the mounting shaft 10, so that the mixing tank 3 is tilted. The state of the concrete in the mixing tank 3 is adjusted so that the falling speed of the concrete in the mixing tank 3 is increased. Moreover, by controlling the degree of tilt of the mixing tank 3, the discharge speed of the concrete can be controlled, which facilitates the discharge of concrete from the mixing tank 3 and avoids excessive concrete residue in the mixing tank 3. It also avoids the construction speed being reduced due to the low discharge speed of the concrete. The raw materials can be mixed by the mixing tank 3 and the concrete mixing components and discharged directly to the construction position through the discharge pipe 27. This avoids the need for manual handling or trolley transportation, reduces labor input, and increases the speed of concrete paving construction.

[0022] Specifically, a support plate 29 is fixedly installed on the top of the mounting bracket 2, and a rubber pad 30 is fixedly installed on the top of the support plate 29. The top of the rubber pad 30 overlaps with the bottom of the mixing tank 3. When the output end of the hydraulic push rod 6 pulls the mixing tank 3 to reset through the upper mounting sleeve 7 and the upper hinge seat 8, the bottom of the mixing tank 3 contacts the top of the rubber pad 30. The rubber pad 30 buffers the mixing tank 3, preventing the bottom of the mixing tank 3 from being hit, thus facilitating the protection of the mixing tank 3.

[0023] Specifically, the concrete mixing assembly includes a mixing motor 12 fixedly installed at the bottom of the mixing tank 3. A rotating shaft 13 is fixedly installed at the output end of the mixing motor 12. A mounting housing 14 is fixedly installed at the top of the rotating shaft 13. A rotating shaft 15 is rotatably installed inside the mounting housing 14. A gear 16 is fixedly installed at the bottom end of the rotating shaft 15. A circular gear rail 17 is meshed on the surface of the gear 16. A protective housing 18 is fixedly installed on the outer surface of the circular gear rail 17. The protective housing 18 is fixedly installed on the lower side wall of the mixing tank 3. A driving synchronous pulley 19 is fixedly installed at the top of the rotating shaft 15. A synchronous belt 20 is meshed on the surface of the driving synchronous pulley 19. A driven synchronous pulley 21 is meshed inside the synchronous belt 20. Four mixing paddles 22 are fixedly installed and arranged in a circular array. The mixing paddles 22 are made of metal and are rotatably mounted inside the mounting housing 14. The mixing motor 12 drives the mounting housing 14 to rotate via the rotating shaft 13. The mounting housing 14 drives the rotating shaft 15 and the mixing paddles 22 to perform circular motion, causing the gear 16 to roll inside the circular gear track 17. The rotating shaft 15 drives the mixing paddles 22 to rotate via the driving synchronous pulley 19, the synchronous belt 20, and the driven synchronous pulley 21. The mixing paddles 22 can rotate on their own axis while revolving around the central axis, which increases the speed of concrete mixing and reduces the time required for the concrete to be mixed evenly.

[0024] Specifically, a protective cover 28 is fixedly installed on the left side of the mixing tank 3, and the electric push rod 24 is located inside the protective cover 28. The protective cover 28 can protect the electric push rod 24, preventing dust generated by mixing from adhering to the output end of the electric push rod 24, and also preventing the electric push rod 24 from being directly impacted.

[0025] In use: Concrete raw materials are added into the mixing tank 3. The output end of the mixing motor 12 drives the rotating shaft 13 to rotate, which in turn drives the mounting housing 14 to rotate. The mounting housing 14 then drives the rotating shaft 15 and the mixing paddle 22 to make circular motion, so that the mounting plate 23 mixes the concrete raw materials. At the same time, the opening and closing plate 25 drives the gear 16 to make circular motion, so that the gear 16 rolls inside the circular gear track 17. The rolling gear 16 drives the rotating shaft 15 to rotate, which in turn drives the driving synchronous wheel 19 to rotate. The driving synchronous wheel 19 drives the driven synchronous wheel 21 to rotate through the synchronous belt 20, and the driven synchronous wheel 21 drives the mixing paddle 22 to rotate, so that the mixing paddle 22 can rotate on its own when it makes circular motion.

[0026] After the concrete is mixed, the output end is driven by the electric push rod 24 to move the opening and closing plate 25 upward. The opening and closing plate 25 then drives the guide rod 26 to slide inside the mounting plate 23, so that the guide rod 26 no longer obstructs the discharge pipe 27, allowing the concrete to be discharged from the mixing tank 3 through the discharge pipe 27. At the same time, the output end is driven by the hydraulic push rod 6 to move the upper mounting sleeve 7, causing the upper mounting sleeve 7 to push the mixing tank 3 to flip through the upper hinge seat 8. This causes the mixing tank 3 to drive the rotating block 11 to rotate on the surface of the mounting shaft 10, making the mixing tank 3 tilted. This increases the falling speed of the concrete in the mixing tank 3, allowing all the concrete in the mixing tank 3 to be discharged. Moreover, by controlling the degree of tilt of the mixing tank 3, the discharge speed of the concrete can be controlled.

[0027] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
