Description

Technical Field

[0001] This utility model relates to the field of building construction technology, specifically a material mixer for building construction. Background Technology

[0002] Construction engineering refers to the engineering entity formed by the construction of various buildings and their ancillary facilities, as well as the installation of supporting lines, pipelines and equipment. During construction, various materials are required, and most of these materials need to be mixed before use, necessitating the use of a mixer. A mixer is a type of construction machinery mainly used for mixing building materials such as cement, sand, gravel, and various dry mortars. It is a machine with a bladed shaft rotating in a cylinder or trough to mix various raw materials into a mixture or a suitable consistency. There are many types of mixers, including forced mixers, single-shaft mixers, and twin-shaft mixers, etc.

[0003] The existing utility model with authorization announcement number CN217773985U discloses a material mixer for building construction, including a machine shell, a drive motor fixedly installed on the upper surface of the machine shell, a rotating shaft fixedly installed at the output end of the drive motor, a set of mixing plates fixedly installed on the outer surface of the rotating shaft, an mounting plate fixedly installed on the outer surface of the rotating shaft, and an auxiliary rotating shaft rotatably connected to the lower surface of the mounting plate through a bearing.

[0004] Using the above technical solution, materials are added to the crushing chamber during use. The set working motor drives the crushing shaft and crushing teeth to rotate, thereby cutting and crushing the materials in the crushing chamber. The crushed materials flow out under the pressure of the guide plate. The crushed materials can improve the quality of the mixed product and improve the working efficiency of the mixing work. However, the materials stirred in the above technical solution are sticky and will stick to the inner wall of the mixer. If they are not cleaned in time after use, dried materials will accumulate on the inner wall of the mixer, which is difficult to clean and affects the subsequent use of the mixer.

[0005] Therefore, those skilled in the art provide a material mixer for construction engineering to solve the problems mentioned in the background art. Utility Model Content

[0006] The purpose of this utility model is to provide a material mixer for construction engineering to solve the problems mentioned in the background art.

[0007] To achieve the above objectives, this utility model provides the following technical solution:

[0008] A material mixer for construction engineering includes a shell, and a cleaning mechanism is provided inside the shell.

[0009] The cleaning mechanism includes a water pump. The outer surface of the housing is fixedly connected to the outer surface of the water pump. A water tank is fixedly installed on the outer surface of the housing. The input end of the water pump passes through the water tank and extends into the interior of the water tank. The output end of the water pump is fixedly connected to a water pipe. The end of the water pipe away from the water pump is fixedly connected to a sealed rotary joint. The output end of the sealed rotary joint is fixedly connected to a rotating shaft. Several stirring blades are fixedly connected to the outer surface of the rotating shaft. Two scrapers are fixedly connected to the outer surface of the rotating shaft. The outer surface of each scraper is in contact with the inner wall of the housing. A pipe is opened in the interior of each stirring blade and the interior of the rotating shaft. A high-pressure nozzle is fixedly connected to the inner wall of each stirring blade.

A first bevel gear is fixedly connected to the output end of the servo motor. A second bevel gear is meshed with the outer surface of the first bevel gear. The inner wall of the second bevel gear is fixedly connected to the outer surface of the rotating shaft.

[0010] As a further embodiment of this utility model: the outer surface of the outer shell is fixedly connected to a discharge port, and the inner wall of the discharge port is slidably connected to a baffle.

[0011] As a further improvement of this utility model: four support legs are fixedly connected to the bottom surface of the outer shell, and two auxiliary legs are fixedly connected to the bottom surface of the water tank.

[0012] As a further improvement of this utility model: the inner wall of the outer shell is fixedly connected to two fixing rods, and the upper surface of one of the fixing rods is fixedly connected to four fixing blocks, and the upper surface of each fixing block is fixedly connected to the outer surface of the water pipe.

[0013] As a further improvement of this utility model: the inner wall of the outer shell is fixedly connected to two fixing rods, and the upper surface of one of the fixing rods is fixedly connected to four fixing blocks, and the upper surface of each fixing block is fixedly connected to the outer surface of the water pipe.

[0016] Compared with the prior art, the beneficial effects of this utility model are:

[0017] This invention features a water pump, water tank, water pipes, water inlet, sealed rotary joint, scraper, conduit, and high-pressure nozzle. The scraper is connected to the rotating shaft and rotates with it. After use, material residue remains on the inner wall of the mixer. The rotating scraper removes this residue. The water pump transports water from the tank to the high-pressure nozzle via the pipes. The nozzle sprays water onto the inner wall of the outer casing. The combined effect of the scraper, water pump, water tank, pipes, conduit, and high-pressure nozzle effectively cleans the residue. Because the high-pressure nozzle and conduit are located inside the mixing blades and rotating shaft, they rotate with the blades, ensuring more even water distribution and better cleaning. The sealed rotary joint guarantees a stable and continuous water supply during cleaning, ensuring smooth operation. This design effectively removes residual material from the mixer, preventing its accumulation and ensuring its continued operation. Attached Figure Description

[0023] Please see Figure 1-4 A material mixer for construction engineering includes a shell 1, and a cleaning mechanism 2 is provided inside the shell 1.

[0024] The cleaning mechanism 2 includes a water pump 201. The outer surface of the housing 1 is fixedly connected to the outer surface of the water pump 201. The outer surface of the housing 1 is fixedly connected to the discharge port 3. The inner wall of the discharge port 3 is slidably connected to a baffle 4. By setting the discharge port 3 and the baffle 4, the mixed material can be discharged, which is convenient for workers to collect and use. The baffle 4 can block the material inside the mixer when it is not necessary to discharge the material, preventing it from leaking out from the discharge port 3 before it is properly mixed.

[0025] A water tank 203 is fixedly installed on the outer surface of the outer casing 1. The input end of the water pump 201 passes through the water tank 203 and extends into the interior of the water tank 203. Four support legs 6 are fixedly connected to the bottom surface of the outer casing 1. Two auxiliary legs 7 are fixedly connected to the bottom surface of the water tank 203. By setting the support legs 6 and auxiliary legs 7, the mixer is supported. The auxiliary legs 7 can assist the support legs 6 in supporting the water tank 203, which can increase the stability of the mixer.

[0026] The output end of the water pump 201 is fixedly connected to a water pipe 202. The end of the water pipe 202 away from the water pump 201 is fixedly connected to a sealing rotary joint 212. Two fixing rods 5 are fixedly connected to the inner wall of the outer casing 1. Four fixing blocks 11 are fixedly connected to the upper surface of one of the fixing rods 5. The upper surface of each fixing block 11 is fixedly connected to the outer surface of the water pipe 202. By setting the fixing rods 5 and fixing blocks 11, the fixing rods 5 can fix the sealing rotary joint 212 and the rotating shaft 204 to prevent the sealing rotary joint 212 from shaking and being damaged during the operation of the mixer. The fixing blocks 11 can fix the water pipe 202 and improve the stability of the water pipe.

[0027] The output end of the sealed rotary joint 212 is fixedly connected to a rotating shaft 204. Several stirring blades 205 are fixedly connected to the outer surface of the rotating shaft 204. Two scrapers 209 are fixedly connected to the outer surface of the rotating shaft 204. The outer surface of each scraper 209 is in contact with the inner wall of the outer shell 1. The side of the two fixing rods 5 away from the inner wall of the outer shell 1 is fixedly connected to a first bearing 10. The inner ring of the first bearing 10 is fixedly connected to the outer surface of the rotating shaft 204. By setting the first bearing 10, it plays the role of assisting the fixing rods 5 in fixing the rotating shaft 204, ensuring that the fixing rods 5 can play a fixing role without rotating with the rotating shaft 204.

[0028] Each stirring blade 205 and the rotating shaft 204 share a common pipe 211. A high-pressure nozzle 210 is fixedly connected to the inner wall of each stirring blade 205. The input end of each high-pressure nozzle 210 is connected to the output end of the pipe 211. A second bearing 8 is fixedly connected to the outer surface of the rotating shaft 204. The outer ring of the second bearing 8 is fixedly connected to the inner wall of the outer casing 1. By setting the second bearing 8, the rotating shaft 204 is assisted in rotating. The second bearing 8 prevents the rotating shaft 204 from contacting the outer casing 1, reduces friction during rotation, and makes it rotate more smoothly.

[0029] A servo motor 208 is fixedly connected to the bottom surface of the outer casing 1. A first bevel gear 207 is fixedly connected to the power output end of the servo motor 208. A second bevel gear 206 is meshed with the outer surface of the first bevel gear 207. The inner wall of the second bevel gear 206 is fixedly connected to the outer surface of the rotating shaft 204. A motor housing 9 is fixedly connected to the bottom surface of the outer casing 1. The sides of the two fixing rods 5 that are close to each other are fixedly connected to the outer surface of the sealing rotary joint 212. The servo motor 208 is located inside the motor housing 9. By setting the motor housing 9, the servo motor 208, the first bevel gear 207 and the second bevel gear 206 can be protected to prevent damage caused by external forces and to avoid affecting the normal operation of the mixer.

[0030] The working principle of this utility model is as follows: When in use, first close the baffle 4, then pour the material to be stirred into the mixer and add an appropriate amount of water. Then turn on the power of the servo motor 208. The power of the servo motor 208 can drive the first bevel gear 207 to rotate. The first bevel gear 207 drives the second bevel gear 206 to rotate. The rotating shaft 204 and the stirring blade 205 will rotate with the second bevel gear 206. Then the stirring blade 205 will start to mix and stir the material. After the mixture is evenly mixed, open the baffle 4 to let the material flow out from the discharge port 3. During the flow process, the servo motor 208 is kept on so that the scraper 209 can push the undischarged material to the discharge port 3. After the mixer is used, turn off the servo motor 208.

[0031] When the mixer needs cleaning, first fill the water tank 203, turn on the servo motor 208, then connect and turn on the power to the water pump 201. The water in the tank 203 is pumped into the water pipe 202 by the water pump 201, and then into the pipe 211 inside the rotating shaft 204. Next, it is pumped into the pipe 211 inside each mixing blade 205, and finally sprayed onto the inner wall of the mixer through the high-pressure nozzle 210. Because the scraper 209 and the mixing blades 205 are all connected to the rotating shaft 204, the scraper... Both scraper 209 and stirring blade 205 rotate with the rotation of rotating shaft 204. High-pressure nozzle 210 also rotates with the rotation of stirring blade 205. Scraper 209 scrapes away residual material inside the mixer during rotation, while high-pressure nozzle 210 sprays water evenly inside the mixer during rotation. With the cooperation of both, residual material inside the mixer can be cleaned. Finally, the cleaned material is discharged through discharge port 3. After cleaning, water pump 201, servo motor 208 and baffle 4 are turned off for next use.

[0032] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
