[0015] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.
[0016] like Figure 1 As shown,
[0017] A concrete mixing device, characterized in that it includes a frame 2, a mixing drum 3 is fixedly connected to the frame 2, a discharge pipe 4 is provided at the lower end of the mixing drum 3, two symmetrical feeding ports 5 are provided at the upper end of the mixing drum 3, a mixing assembly is provided on the mixing drum 3, a push rod motor 6 is fixedly connected to the frame 2, a first drive motor 7 is fixedly connected to the push rod of the push rod motor 6, a support rod 8 is fixedly connected to the output shaft of the first drive motor 7, a well frame 9 is sleeved at the lower end of the support rod 8, a mixing blade 10 is provided at the bottom end of the support rod 8, and the well frame 9 and the mixing blade 10 can move up and down in the discharge pipe 4.
[0018] In this embodiment, the raw materials of concrete are added into the mixing drum 3 from two feeding ports 5 respectively, so that the raw materials can be evenly mixed, and then stirred by the stirring assembly. The concrete after stirring is discharged through the discharge pipe 4. When discharging, large pieces of solidified concrete are intercepted by the cross frame 9, and the large pieces of solidified concrete are driven to rise by the push rod motor 6, so that it returns to the stirring assembly for re-stirring, and the unsolidified concrete passes through the cross frame 9, and the first drive motor 7 drives the support rod 8 and the stirring blade 10 to rotate, and the concrete before discharging is stirred again to make it more uniform.
[0019] In this embodiment, the stirring assembly includes two rotating rods 11, which are symmetrically rotatably connected in the mixing drum 3, and a plurality of stirring rods 12 are fixedly connected to the rotating rods 11. The mixing drum 3 is symmetrically provided with second drive motors 13, and the output shaft of the second drive motor 13 is connected to the rotating rods 11. The two second drive motors 13 drive the rotating rods 11 and the stirring rods 12 to rotate, and the concrete is stirred, wherein one of the second drive motors 13 rotates forward and the other second drive motor 13 rotates reversely, so that the stirring efficiency is higher.
[0020] In this embodiment, a scraper 14 is fixedly connected to the side wall of the rotating rod 11, and the scraper 14 contacts the inner wall of the mixing drum 3. The scraper 14 scrapes off the concrete raw materials remaining on the inner wall of the mixing drum 3 to prevent this part of the raw materials from not being mixed.
[0021] In this embodiment, a stirring bar 15 is obliquely arranged between two upper and lower adjacent stirring rods 12. The stirring bar 15 is obliquely arranged to stir the longitudinal space in the stirring drum 3, thereby improving the stirring efficiency.
[0022] In this embodiment, a solenoid valve 16 is provided on the discharge pipe 4. The discharge is controlled by the solenoid valve 16.
