DETAILED DESCRIPTION OF THE EMBODIMENTS

[0021] In order to further explain the technical solution of the utility model, the following is elaborated in detail through specific embodiments.

[0022] Please refer to Figure 1, the present utility model provides a mixer for a concrete mixing plant, which includes a barrel body 1, a discharge port 2, a stirring shaft 3, a motor 4 and a split-type cleaning mechanism 5. A discharge port 2 is arranged on the side of the bottom surface of the barrel body 1. A stirring shaft 3 is rotatably installed in the middle of the inner side of the barrel body 1. A motor 4 is installed in the middle of the bottom surface of the barrel body 1. The output end of the top of the motor 4 extends into the inner side of the barrel body 1 and is connected to the stirring shaft 3. The stirring shaft 3 is driven by the motor 4 to rotate. A split-type cleaning mechanism 5 is arranged at the top end of the stirring shaft 3.

[0023] Please refer to Figures 2 - 5 , in the present utility model, the split-type cleaning mechanism 5 includes a docking shaft 51, a sleeve 52, a connecting frame 53, a longitudinal brush 54, a limiting frame 55, a mounting hole 56, a docking sleeve 57 and a positioning bolt 58. A docking shaft 51 is integrally arranged at the top end of the stirring shaft 3. A sleeve 52 is sleeved outside the docking shaft 51. Connecting frames 53 are symmetrically welded on both sides of the outside of the sleeve 52. A longitudinal brush 54 is installed at the end of the connecting frame 53 by screws. The top end of the sleeve 52 is rotatably connected to the limiting frame 55 through a bearing. The limiting frame 55 is L-shaped. A mounting hole 56 is opened at the side of the end of the limiting frame 55. A docking sleeve 57 is installed at the top of the outer wall of the barrel body 1 by screws. The end of the limiting frame 55 can be longitudinally inserted into the inner side of the docking sleeve 57. A positioning bolt 58 is screwed into the threaded hole on the outer wall of the docking sleeve 57. The positioning bolt 58 can be screwed into the inner side of the docking sleeve 57 to be docked with the mounting hole 56, so as to lock and fix the limiting frame 55 and the docking sleeve 57. After the position of the limiting frame 55 is fixed, it can block the top of the sleeve 52 to prevent it from detaching from the outside of the docking shaft 51.

[0024] Furthermore, the cross-section of the longitudinal brush 54 is arc-shaped, and the longitudinal brush 54 matches the radian of the inner wall of the barrel body 1, so that the whole longitudinal brush 54 can be in close contact with the inner wall of the barrel body 1 to achieve a better wiping and cleaning effect.

[0025] Furthermore, a protrusion 59 is integrally arranged at the top end of the docking shaft 51. The protrusion 59 is in a shape of a straight line. A clamping groove 510 is opened on the inner top surface of the sleeve 52. The shape and size of the clamping groove 510 match those of the protrusion 59. When the sleeve 52 and the docking shaft 51 are sleeved with each other, the protrusion 59 can be clamped into the inner side of the clamping groove 510, so as to lock the sleeve 52 to restrict its self-rotation and ensure that the sleeve 52 can rotate synchronously with the stirring shaft 3.

[0026] Furthermore, when the protrusion 59 and the clamping groove 510 are clamped with each other, the longitudinal brush 54 is staggered from the position of the blades on the surface of the stirring shaft 3. The protrusion 59 and the clamping groove 510 can help the sleeve 52 to be positioned at a suitable installation angle to ensure that the longitudinal brush 54 will not affect the stirring shaft 3.

[0027] Further explanation: A transverse brush 511 is installed at the bottom of the inner side of the longitudinal brush 54, and the transverse brush 511 is perpendicular to the longitudinal brush 54. The longitudinal brush 54 can wipe and clean the inner side wall of the barrel body 1, and the transverse brush 511 can wipe and clean the inner bottom surface of the barrel body 1, further expanding the cleaning range of the split cleaning mechanism 5 and improving the cleaning effect.

[0028] Further explanation: When the sleeve 52 is fully sleeved outside the docking shaft 51, the longitudinal brush 54 will closely adhere to the inner side wall of the barrel body 1, and the transverse brush 511 will closely adhere to the inner bottom surface of the barrel body 1, ensuring that the longitudinal brush 54 and the transverse brush 511 can play their cleaning roles.

[0029] The working principle is as follows:

[0030] First, place the barrel body 1 on a flat ground to ensure that the whole barrel body 1 is stable and does not shake. Then connect the motor 4 to an external control box for centralized control, and the stirring work can start.

[0031] Second, when carrying out the stirring work, first start the motor 4, and then add materials such as water, sand, stones, and cement into the barrel body 1. The motor 4 drives the stirring shaft 3 to rotate, so as to stir and mix the materials inside the barrel body 1. After the materials reach the predetermined mixing degree, the discharge port 2 can be opened to empty the materials inside the barrel body 1, thus completing the stirring work.

[0032] Third, after the stirring is completed, it is necessary to clean the inside of the barrel body 1 in time. Otherwise, it will be more difficult to remove after the materials solidify. A split cleaning mechanism 5 is provided at the top of the stirring shaft 3. Before the cleaning operation, the sleeve 52 needs to be installed first. The specific operation is as follows: Sleeve the sleeve 52 from top to bottom outside the docking shaft 51, and then adjust the angle of the sleeve 52 until the protrusion 59 is engaged inside the card slot 510, so that the sleeve 52 and the docking shaft 51 are locked as a whole, ensuring that the sleeve 52 can rotate synchronously with the stirring shaft 3. During the process of sleeving the sleeve 52 and the docking shaft 51, the end of the limit frame 55 should be aligned with the docking sleeve 57. When the sleeve 52 and the docking shaft 51 are sleeved together, the end of the limit frame 55 can be inserted into the inside of the docking sleeve 57 synchronously. Then tighten the positioning bolt 58 and screw it into the installation hole 56 inside, so as to lock and fix the limit frame 55 and the docking sleeve 57. After the position of the limit frame 55 is fixed, it can block the top of the sleeve 52 to prevent it from detaching from the outside of the docking shaft 51, and the installation and fixation of the sleeve 52 can be completed. The operation is simple and the learning cost is low.

[0033] Fourth, when performing the cleaning operation, first start the motor 4, then add clean water and cleaning agent into the barrel body 1. The motor 4 drives the stirring shaft 3 to rotate, and the connecting frame 53 can rotate synchronously with the stirring shaft 3, so that the longitudinal brush 54 at the end of the connecting frame 53 moves along the inner wall of the barrel body 1, and the longitudinal brush 54 wipes and removes the materials adhered to the inner wall of the barrel body 1, thus realizing the cleaning of the barrel body 1, which can reduce the manual labor amount and improve the cleaning work efficiency. By installing a transverse brush 511 at the bottom of the longitudinal brush 54, the longitudinal brush 54 can wipe and clean the inner wall of the barrel body 1, while the transverse brush 511 can wipe and clean the inner bottom surface of the barrel body 1, further expanding the cleaning range of the split cleaning mechanism 5 and improving the cleaning effect.

[0034] Fifth, after the cleaning is completed, only need to loosen the positioning bolt 58 and screw it out from the inside of the installation hole 56, then the connection and fixation between the limiting frame 55 and the docking sleeve 57 can be released. At this time, only need to lift the connecting frame 53 upward, and the sleeve 52 can be detached from the outside of the docking shaft 51, thus completing the disassembly. The operation is convenient and will not affect the normal operation and use of the stirring shaft 3.

[0035] The utility model provides a mixer for a concrete mixing station. By setting a split cleaning mechanism 5 at the top end of the stirring shaft 3, the motor 4 drives the stirring shaft 3 to rotate, and the connecting frame 53 can rotate synchronously with the stirring shaft 3, so that the longitudinal brush 54 at the end of the connecting frame 53 moves along the inner wall of the barrel body 1, and the longitudinal brush 54 wipes and removes the materials adhered to the inner wall of the barrel body 1, thus realizing the cleaning of the barrel body 1, which can reduce the manual labor amount and improve the cleaning work efficiency. After the cleaning is completed, only need to loosen the positioning bolt 58 and screw it out from the inside of the installation hole 56, then the connection and fixation between the limiting frame 55 and the docking sleeve 57 can be released. At this time, only need to lift the connecting frame 53 upward, and the sleeve 52 can be detached from the outside of the docking shaft 51, thus completing the disassembly. The operation is convenient and will not affect the normal operation and use of the stirring shaft 3. By installing a transverse brush 511 at the bottom of the longitudinal brush 54, the longitudinal brush 54 can wipe and clean the inner wall of the barrel body 1, while the transverse brush 511 can wipe and clean the inner bottom surface of the barrel body 1, further expanding the cleaning range of the split cleaning mechanism 5 and improving the cleaning effect.
