Description

Technical Field

[0001] This utility model relates to the field of cement adhesive mixing technology, and more specifically, to a cement mortar mixer with a detachable discharge port. Background Technology

[0002] Cement is frequently used in construction projects, and its quality is crucial to the entire project. The quality of its mixing directly affects the quality of cement mortar, which in turn relates to the performance and quality of cement and related products. Therefore, cement mortar mixers are generally used for mixing cement.

[0003] However, during the mixing process, cement dust can easily drift from the top of the mixing drum into the surrounding air. This cement dust can be inhaled by operators, and long-term inhalation of cement dust is harmful to health and may cause respiratory diseases.

[0004] A search revealed that Chinese patent CN222768716U discloses a cement mortar mixer. This structure, through the installation of a lead screw sleeve, piston, and nozzle, uses a reciprocating lead screw to drive the piston to slide back and forth within the mixing chamber. External water is drawn into the chamber and then injected into the nozzle, where it is atomized and sprayed out to suppress rising cement dust, preventing it from dispersing into the air and protecting the respiratory health of operators. Furthermore, by incorporating incomplete gears and other gears, the meshing of these gears allows for simultaneous rotation of the lead screw and mixing plate, eliminating the need for a separate power source for the lead screw and reducing operating costs. It also facilitates adjustment of the mixing plate height, thus expanding the mixing range and improving the mixing efficiency of cement mortar.

[0005] However, in actual use, this structure uses incomplete gears and other devices to drive the mixing plate to rotate. When the mixing plate is worn, deformed, or damaged, it cannot be disassembled, so the entire mixing device must be replaced, which increases maintenance costs. Furthermore, during maintenance, it is necessary to disassemble surrounding complex parts to access the mixing plate, which prolongs maintenance time and affects the normal operating efficiency of the equipment.

[0029] 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.

[0030] The embodiments disclosed in this application are as follows: Figure 1-5 The detachable discharge port cement mortar mixer shown includes a fixed frame 1, a support frame 2 fixedly installed on the top of the fixed frame 1, a movable plate 3 slidably installed inside the support frame 2, and a disassembly mechanism installed on the top of the movable plate 3.

[0031] The disassembly mechanism includes a motor 4 fixedly installed on the top of the movable plate 3. A rotating shaft 5 is fixedly installed at the output end of the motor 4. An upper fixed plate 6 is fixedly installed at one end of the rotating shaft 5. A lower fixed plate 7 is connected to the internal thread of the upper fixed plate 6. Threaded holes are opened on the surfaces of both the upper fixed plate 6 and the lower fixed plate 7. Bolts 8 are connected to the internal threads of the threaded holes. Nuts 9 are connected to the bottom threads of the bolts 8.

[0032] Multiple springs 10 are fixedly installed at the bottom of the lower fixed plate 7. A baffle plate 11 is fixedly installed at one end of the spring 10. A stirring blade 12 is fixedly installed at the bottom of the lower fixed plate 7.

[0033] When the motor 4 is turned on, the shaft 5 at the output end of the motor 4 drives the upper fixed plate 6 to rotate. Since the upper fixed plate 6 and the lower fixed plate 7 are connected by bolts 8 and nuts 9, the lower fixed plate 7 rotates accordingly, thereby causing the stirring blades 12 fixed at the bottom of the lower fixed plate 7 to stir the raw materials in the stirring drum 13.

[0034] During the mixing process, it is inevitable to encounter sudden changes in local resistance caused by uneven material distribution. At this time, the spring 10 undergoes compression deformation under the impact force, which drives the baffle plate 11 to move upward. By tightly pressing against the bottom end face of the nut 9, the rigid support of the baffle plate 11 restricts the loosening tendency of the nut 9 along the axial direction of the bolt 8, thereby enhancing stability.

[0035] Reference Figure 2-4 As shown, a stirring drum 13 is fixedly installed on the top of the fixed frame 1. A discharge port 14 is opened on the surface of the stirring drum 13. A discharge pipe 15 is threadedly connected inside the discharge port 14. A solenoid valve is installed on one side of the discharge pipe 15.

[0036] A fixing ring 16 is fixedly provided on the surface of the discharge pipe 15, and a sealing ring 17 is fixedly provided on the top of the fixing ring 16. A sealing groove is opened on the surface of the mixing drum 13, and the sealing ring 17 is inserted into the sealing groove.

[0037] After mixing is complete, if discharge is required, open the solenoid valve on one side of the discharge pipe 15. The mixed cement mortar is discharged through the discharge port 14 and the discharge pipe 15. The sealing ring 17 at the top of the fixing ring 16 on the surface of the discharge pipe 15 is inserted into the sealing groove on the surface of the mixing drum 13 to ensure that there is no leakage during the discharge process. If the discharge pipe 15 needs to be replaced, it can be directly unscrewed from the discharge port 14 to achieve the detachability of the discharge port.

[0038] Reference Figure 3-4 As shown, a dust suppression mechanism is provided on the top of the movable plate 3. The dust suppression mechanism includes a collection box 18 fixedly installed on the top of the movable plate 3. A conveying pipe 19 is provided through the surface of the collection box 18. A U-shaped distribution frame 20 is provided through one end of the conveying pipe 19. Multiple suction hoppers 21 are provided through the bottom of the U-shaped distribution frame 20. A fixing column 22 is fixedly installed on the top of the U-shaped distribution frame 20. One end of the fixing column 22 is connected to the surface of the movable plate 3.

[0039] A suction fan 23 is fixedly installed on the top of the collection box 18, and a pipe 24 is provided through one end of the suction fan 23;

[0040] During the mixing and discharging process, the suction fan 23 on the top of the collection box 18 is activated. The suction fan 23 generates suction force at the bottom of the U-shaped distribution frame 20 through the conveying pipe 19, which draws the dust generated during the mixing process into the U-shaped distribution frame 20. The dust then enters the collection box 18 through the conveying pipe 19 for collection, preventing dust from flying and playing a dust suppression role. The dust in the collection box 18 is discharged to the outside through the discharge pipe 24.

[0041] Reference Figure 2 , 5As shown, a stepper motor 25 is fixedly installed on the top of the support frame 2, and a threaded rod 26 is fixedly provided at the output end of the stepper motor 25. The threaded rod 26 is threadedly connected to the moving plate 3, and multiple support legs 27 are fixedly provided at the bottom of the fixed frame 1.

[0042] Cement, mortar and other raw materials are put into the mixing drum 13 in proportion. The stepper motor 25 at the top of the support frame 2 is started, and the threaded rod 26 at its output end rotates, which drives the moving plate 3 to slide down inside the support frame 2, so that the mixing blade 12 descends to a suitable position inside the mixing drum 13.

[0043] Working principle of this utility model:

[0044] This utility model is a cement mortar mixer with a detachable discharge port. When the device is in use, cement, mortar and other raw materials are put into the mixing drum 13 in proportion. The stepper motor 25 on the top of the support frame 2 is started, and the threaded rod 26 at its output end rotates, driving the moving plate 3 to slide downward inside the support frame 2, so that the mixing blade 12 descends to a suitable position inside the mixing drum 13.

[0045] Then, the motor 4 is turned on. The shaft 5 at the output end of the motor 4 drives the upper fixed plate 6 to rotate. Since the upper fixed plate 6 and the lower fixed plate 7 are connected by bolts 8 and nuts 9, the lower fixed plate 7 rotates accordingly, thereby causing the stirring blades 12 fixed at the bottom of the lower fixed plate 7 to stir the raw materials in the stirring drum 13.

[0046] During the mixing process, it is inevitable to encounter sudden changes in local resistance caused by uneven material distribution. At this time, the spring 10 undergoes compression deformation under the impact force, which drives the baffle plate 11 to move upward. By tightly pressing against the bottom end face of the nut 9, the rigid support of the baffle plate 11 restricts the loosening tendency of the nut 9 along the axial direction of the bolt 8, thereby enhancing stability.

[0047] After mixing is complete, if discharge is required, open the solenoid valve on one side of the discharge pipe 15. The mixed cement mortar is discharged through the discharge port 14 and the discharge pipe 15. The sealing ring 17 at the top of the fixing ring 16 on the surface of the discharge pipe 15 is inserted into the sealing groove on the surface of the mixing drum 13 to ensure that there is no leakage during the discharge process. If the discharge pipe 15 needs to be replaced, it can be directly unscrewed from the discharge port 14 to achieve the detachability of the discharge port.

[0048] During the mixing and discharging process, the suction fan 23 on the top of the collection box 18 is activated. The suction fan 23 generates suction force at the bottom of the U-shaped distribution frame 20 through the conveying pipe 19, which draws the dust generated during the mixing process into the U-shaped distribution frame 20. The dust then enters the collection box 18 through the conveying pipe 19 for collection, preventing dust from flying and playing a dust suppression role. The dust in the collection box 18 is discharged to the outside through the discharge pipe 24.

[0049] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
