Description

Technical Field

[0001] This utility model belongs to the field of dry-mixed mortar technology, and in particular relates to a mixing device for dry-mixed mortar. Background Technology

[0002] Dry-mixed mortar, also known as premixed mortar, is a new type of material made by mixing sand, cement, fly ash, and additives in a certain proportion according to certain strength requirements.

[0003] Traditional mixing devices typically use simple rotating mixing blades. While they can achieve overall mixing, the mixing blades are not very effective at completely dispersing small agglomerates formed in mortar due to factors such as moisture and compression. These agglomerates are often simply trapped in the mortar during the mixing process and cannot fully participate in the chemical reaction with cement, water, and other components, ultimately forming weak points in strength. Utility Model Content

[0004] The purpose of this invention is to provide a mixing device for dry-mixed mortar. By incorporating a mixing mechanism, the device utilizes a combined revolution and rotation motion mode to expand the mixing range of the mixing blades within the mixing drum, avoiding dead zones and enabling the dry-mixed mortar to be mixed more thoroughly and evenly. Furthermore, during the mixing process, two cleverly designed crushing discs, with their special serrated edges and the impact force generated by high-speed rotation, can effectively break up large particles in the dry-mixed mortar that have clumped and settled due to moisture or long-term storage. This solves the problem that traditional mixing devices typically use simple rotating mixing blades, which, while achieving overall mixing, have limited effectiveness in dispersing small agglomerates formed in the mortar due to moisture, compression, or other factors.

[0005] To solve the above-mentioned technical problems, this utility model is achieved through the following technical solution:

[0006] This utility model is a mixing device for dry-mixed mortar, including a base plate, on which a mixing mechanism and a lifting mechanism are provided;

[0007] The stirring mechanism includes a support frame fixedly connected to the top surface of the base plate. A stirring tank is fixedly connected inside the support frame. A lid is provided on the top of the stirring tank. A motor is fixedly connected to the top surface of the lid. A rotating rod is fixedly connected to the output end of the motor through a coupling. A rotating disk is fixedly connected to the outer wall of the rotating rod. The rotating disk is located inside the lid and is rotatably connected to the inner wall of the lid. Two crushing disks are fixedly connected to the outer wall of the rotating rod. Both crushing disks are located inside the stirring tank.

[0008] The lifting mechanism includes a support base fixedly connected to the top surface of the base plate.

[0009] Furthermore, four rotating rods are threaded through the rotating disk, and all four rotating rods are rotatably connected to the rotating disk.

[0010] Furthermore, gears are fixedly connected to the outer walls of several of the rotating rods, and these gears are located above the rotating disk.

[0011] Furthermore, an internal gear ring is fixedly connected to the inner wall of the bucket lid. The internal gear ring is located above the rotating disk and meshes with several gears.

[0012] Furthermore, several stirring blades are fixedly connected to the outer walls of several rotating rods, and the stirring blades are all located above the crushing disc.

[0013] Furthermore, several baffles are fixedly connected to the top surfaces of the two crushing discs, and a feed pipe is connected to the bottom of the mixing tank. The feed pipe is fixedly connected to the mixing tank, and a valve is provided on the outer wall of the feed pipe.

[0014] Furthermore, an electric push rod is fixedly connected to the top surface of the support base, a support plate is fixedly connected to the output end of the electric push rod, and a plurality of support rods are fixedly connected to the bottom surface of the support plate, with the bottom ends of the plurality of support rods being fixedly connected to the top surface of the bucket lid.

[0015] This utility model has the following beneficial effects:

[0016] 1. By incorporating a stirring mechanism, when the drive motor rotates the rotating rod one and the rotating disk, it causes the four rotating rods two on the rotating disk to revolve around the rotating rod one. With the cooperation of multiple gears and internal gear rings, the rotating rod one can rotate on its own axis during its revolution, thereby causing multiple rotating rods one to drive multiple stirring blades to rotate and mix the dry mortar inside the mixing tank. Compared with existing stirring mechanisms, the combined revolution and rotation motion mode of this device expands the stirring range of the stirring blades in the mixing tank, avoids dead zones in the stirring, and allows the dry mortar to be mixed more fully and evenly. Furthermore, during the mixing process, the two cleverly designed crushing discs, with their special serrated edges and the impact force generated by high-speed rotation, can effectively break up large particles in the dry mortar that have clumped and settled due to moisture or long-term storage, preventing these clumps from affecting the uniformity of the mortar and the final use effect.

[0017] 2. A lifting mechanism is installed to drive an electric push rod to move the support plate upward, which in turn moves the bucket lid upward, opening the mixing bucket and allowing the raw materials to be added inside. During mixing, the electric push rod drives the support plate downward to cover the mixing bucket, forming a closed space. At this time, the motor is turned on to mix the raw materials. By controlling the height of the bucket lid, the crushing disc can crush mortar raw materials of different heights, further improving the overall mixing effect of the device.

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 skilled in the art without creative effort are within the protection scope of the present utility model.

[0028] Please see Figure 1-5 As shown, this utility model is a mixing device for dry-mixed mortar, including a base plate 1, on which a mixing mechanism 2 and a lifting mechanism 3 are provided;

[0029] The stirring mechanism 2 includes a support frame 21 fixedly connected to the top surface of the base plate 1. A stirring tank 22 is fixedly connected inside the support frame 21. A lid 23 is provided on the top of the stirring tank 22. A motor 24 is fixedly connected to the top surface of the lid 23. A rotating rod 25 is fixedly connected to the output end of the motor 24 via a coupling. A rotating disc 26 is fixedly connected to the outer wall of the rotating rod 25. The rotating disc 26 is located inside the lid 23 and is rotatably connected to the inner wall of the lid 23. Two crushing discs 291 are fixedly connected to the outer wall of the mixing tank 22. Both crushing discs 291 are located inside the mixing tank 22. Four rotating rods 27 pass through the rotating disc 26, and the four rotating rods 27 are rotatably connected to the rotating disc 26. Gears 271 are fixedly connected to the outer wall of several rotating rods 27, and the gears 271 are located above the rotating disc 26. An internal gear ring 28 is fixedly connected to the inner wall of the tank cover 23, and the internal gear ring 28 is located above the rotating disc 26. The gear ring 28 meshes with several gears 271. Several stirring blades 29 are fixedly connected to the outer walls of several rotating rods 27. The stirring blades 29 are located above the crushing discs 291. Several baffles 292 are fixedly connected to the top surfaces of the two crushing discs 291. The bottom of the mixing tank 22 is connected to a discharge pipe 293, which is fixedly connected to the mixing tank 22. A valve 294 is provided on the outer wall of the discharge pipe 293. By setting up the stirring mechanism 2, compared with the existing stirring mechanism, the combined motion mode of the revolution and rotation of this device expands the stirring range of the stirring blades 29 in the mixing tank 22, avoids the dead zone of stirring, and makes the dry mortar more fully and evenly mixed. In the process of mixing, the two cleverly set crushing discs 291, with their special serrated edges and the impact force generated by high-speed rotation, can effectively crush large particles of material in the dry mortar that have clumped and settled due to moisture or long-term storage.

[0030] The lifting mechanism 3 includes a support base 31 fixedly connected to the top surface of the base plate 1. An electric push rod 32 is fixedly connected to the top surface of the support base 31. A support plate 33 is fixedly connected to the output end of the electric push rod 32. Several support rods 34 are fixedly connected to the bottom surface of the support plate 33. The bottom ends of the several support rods 34 are fixedly connected to the top surface of the bucket cover 23. By setting up the lifting mechanism 3 and controlling the height of the bucket cover 23, the crushing disc 291 can crush mortar raw materials of different heights, further improving the mixing effect of the overall device.

[0031] A specific application of this embodiment is as follows: By providing a stirring mechanism 2, when the drive motor 24 drives the rotating rod 25 and the rotating disk 26 to rotate, it will drive the four rotating rods 27 on the rotating disk 26 to revolve around the rotating rod 25. With the cooperation of multiple gears 271 and internal gear rings 28, the rotating rod 25 can rotate on its own axis during its revolution, thereby causing multiple rotating rods 25 to drive multiple stirring blades 29 to rotate and stir the dry mortar inside the mixing tank 22. Compared with existing stirring mechanisms, the combined revolution and rotation motion mode of this device expands the stirring range of the stirring blades 29 in the mixing tank 22 and avoids uneven stirring. The mixing dead corners allow the dry-mixed mortar to be mixed more thoroughly and evenly. During the mixing process, the two cleverly designed crushing discs 291, with their special serrated edges and the impact force generated by high-speed rotation, can effectively break up large particles in the dry-mixed mortar that have clumped and settled due to moisture or long-term storage, preventing these clumps from affecting the uniformity of the mortar and the final use effect. When the crushing discs 291 rotate, multiple baffles 292 can throw out the mortar accumulated on the top surface of the crushing discs 291 under the action of centrifugal force. In addition, the feed pipe 293 and the valve 294 work together to open the valve 294 so that the mortar can be discharged after mixing.

[0032] With the lifting mechanism 3 in place, before mixing the mortar, the electric push rod 32 is driven to move the support plate 33 upward, causing multiple support rods 34 to move the bucket lid 23 upward, opening the mixing bucket 22 and allowing the raw materials to be added into the mixing bucket 22. During mixing, the electric push rod 32 is driven to move the support plate 33 downward, covering the mixing bucket 23 with the bucket lid 23 to form a closed space. At this time, the motor 24 is turned on to mix the raw materials. By controlling the height of the bucket lid 23, the crushing disc 291 can crush mortar raw materials of different heights, further improving the overall mixing effect of the device.
