[0026] See also Figure 1 In an embodiment of the present invention, an automatic detection type construction cement mixing device includes a mixing box 101, a mixing port is provided at the top center of the mixing box 101, a feed hopper 102 is fixedly connected above the mixing port, a flap is rotatably connected to the top of the feed hopper 102, the mixing port is provided to facilitate the delivery of solid cement raw materials, and the flap is used to seal the mixing box 101 during mixing to reduce dust emission;

[0027] See also Figure 2 A discharge port is provided in the middle of one side of the mixing box 101, and a stirring assembly for mixing cement is fixedly installed at the bottom of the inner wall of the mixing box 101. The stirring assembly includes a stirring motor 301, and a driving rod 303 is fixedly connected to the output end of the stirring motor 301, and a plurality of stirring rods 304 distributed equidistantly are fixedly connected to the bottom of the driving rod 303, and the plurality of stirring rods 304 are all tilted downward, and the tilt angle of the stirring rods 304 satisfies that the stirring rods 304 are parallel to the top surface of the receiving platform 302; an upper cover of the stirring assembly is provided with a receiving platform 302 fixedly connected to the inner wall of the mixing box 101. Due to the heavy weight of the cement, in order to improve the bearing capacity of the bearing platform, the top surface of the receiving platform 302 is protruded upward to form an inclined surface with a high middle and a low edge; the lowest height of the receiving platform 302 corresponds to the lowest height of the discharge port, so as to facilitate the discharge of the cement after stirring and mixing.

[0028] See also Figure 1 and Figure 2 A discharge door 103 is rotatably installed on the inner wall of the discharge port, a stopper is rotatably connected to one side of the top of the discharge door 103, and a hanging buckle 105 is fixedly connected above the discharge port. The stopper is rotated and engaged with the hanging buckle 105, thereby achieving stable closure of the discharge door 103.

[0029] In order to detect the state of cement in real time during the mixing process and facilitate regulation, a detection mechanism 2 is fixedly installed on one side of the top of the mixing box 101, see Figure 3 The detection mechanism 2 includes a mounting frame 201, a detection cylinder 202 is mounted at the top height of the inner wall of the mounting frame 201, and a detection component 203 is fixedly connected to the output end of the detection cylinder 202. Figure 4 The detection component 203 includes a push sleeve 2032, the bottom of the push sleeve 2032 is slidably connected to the movable sleeve 2031, one end of the inner wall of the movable sleeve 2031 is fixedly installed with a pressure sensor 2036, the middle of the push sleeve 2032 is fixedly connected to a pressurized air intake pipe 2034, one end of the pressurized air intake pipe 2034 close to the movable sleeve ring is fixedly installed with an electric control valve, the end of the pressurized air intake pipe 2034 away from the movable sleeve ring is fixedly connected to the output end of the external air pump, and the edge of one end of the push sleeve 2032 is fixedly connected to a sealing limit ring 2033. The movable detection component 203 travels in the cement slurry. When the various components of the cement are not mixed evenly, the resistance during the travel is inconsistent. The detection component 203 supplies air to the movable sleeve 2031 through the pressurized air inlet pipe 2034, driving the movable sleeve 2031 to expand, and utilizing the resistance of the movable sleeve 2031 during the movement of the movable sleeve 2031 when inserted into the cement to push the movable sleeve 2031 to move and press it, thereby changing the air pressure in the inner cavity of the movable sleeve 2031, and further changing the reading of the pressure sensor 2036, thereby realizing the detection of the change in the travel resistance of the detection component 203, and further realizing the detection of the uniformity of cement mixing.

[0030] See also Figure 3 In order to clean the detection component 203 after a detection operation is completed to avoid interference of cement slurry attached thereon with subsequent detection operations, a cleaning cover plate 204 is fixedly connected to the bottom of the mounting frame 201, and a plurality of cleaning rollers 205 are rotatably installed at the bottom of the inner wall of the cleaning cover plate 204. A friction pad is fixedly connected to the outer wall of the cleaning roller 205. The gap between the plurality of cleaning rollers 205 is consistent with the outer diameter of the movable sleeve 2031. A water inlet 206 is opened in the middle of the inner wall of the cleaning cover plate 204, and a cleaning pipe is fixedly connected to one side of the water inlet 206, and one end of the cleaning pipe is fixedly connected to the output end of the external water pump.

[0031] See also Figure 5 and Figure 6When the detection component 203 detects that the material in a part of the area is uneven, an application is made to perform a corresponding stirring process on the position. Specifically, the present application opens a movable cavity inside the stirring rod 304, and the inner wall of the movable cavity is slidably connected to a lifting seat 404, and the edge of the lifting seat 404 is fixedly connected to a sealing gasket, and a mounting rod 405 is fixed to the top of the lifting seat 404, and a plurality of extension frames 406 are fixedly connected to the top of the mounting rod 405, and a plurality of sliding grooves are opened in the middle of the stirring rod 304, and one end of the plurality of extension frames 406 respectively passes through a plurality of movable grooves 408 and is fixedly connected to a plurality of stirring plates 407; An air intake slip ring 401 is rotatably connected to the bottom, an air guide cavity is provided inside the air intake slip ring 401, a connecting hole 403 is provided on one side of the stirring rod 304 located in the air guide cavity, and a lifting air intake pipe 402 is fixedly connected to one side of the air intake slip ring 401. Air is introduced into the movable cavity through the lifting air intake pipe 402 through the air intake slip ring 401 and the connecting hole 403, driving the lifting seat 404 and the mounting rod 405 to lift and move, thereby driving the extension frame 406 and the stirring plate 407 to rise to the corresponding height, and the rotation of the driving rod 303 drives the extension frame 406 and the stirring plate 407 to rotate, so as to stir and mix the cement slurry at that position.

[0032] See also Figure 4 Furthermore, since the stirring temperature affects the mixing performance of cement, the present application fixes a temperature sensor 2035 on the inner wall of the movable sleeve 2031, and the temperature sensor 2035 is fixedly connected to a limit stopper 2037 on the side close to the pushing sleeve 2032. A plurality of electric heaters 104 are fixedly installed on the inner wall of the mixing box 101. The temperature of the cement is detected by the temperature sensor 2035. When the temperature is too low, the electric heater 104 is started to assist in heating it.

[0033] See also Figure 2 In order to facilitate the addition of liquid material inside the mixing box 101, a liquid material pipe 5 is fixedly connected to the other side of the top of the mixing box 101. In order to facilitate the uniform mixing of the raw materials, an annular diversion pipe 6 is fixedly connected to the bottom of the liquid material pipe 5. The bottom and inner wall of the annular diversion pipe 6 are provided with a plurality of diversion holes to disperse and guide the liquid raw materials.

[0034] When the present invention is used, the flip cover is opened, and the proportioned raw materials are sequentially added into the mixing box 101 from the feed hopper 102, and the liquid raw materials are added in conjunction with the liquid material pipe 5, and at the same time, the stirring motor 301 is started to drive the driving rod 303 and the stirring rod 304 to rotate, so as to stir and mix the materials;

[0035] After stirring for a period of time, the stirring motor 301 stops working, and the detection cylinder 202 drives the detection component 203 to move downward. First, air is filled into the inner cavity of the movable sleeve 2031 by the pressurized air inlet pipe 2034, so that the movable sleeve 2031 is fully expanded (that is, the movable sleeve 2031 moves down to its top edge and contacts the sealing limit ring 2033). When the pressure sensor 2036 reading reaches the preset value, the pressurized air inlet pipe 2034 stops the air intake and is closed by the electric control valve. The detection component 203 continues to move downward and penetrates into the cement slurry. When the detection component 203 moves to an uneven position of the cement slurry (too much water or too much solid raw material), the pressure sensor 2036 reading will change (the resistance is significantly reduced when there is too much water, and the resistance is significantly increased when there are too many solid raw materials). When the change occurs, the movement stroke of the detection cylinder 202 is used to judge the height of the uneven position.

[0036] After the detection is completed, the detection cylinder 202 drives the detection component 203 to rise and reset. When the detection component 203 passes the cleaning cover plate 204, the cleaning roller 205 rotates to drive the friction plate to rotate, and the cement slurry attached to the detection component 203 is removed. Then, the external water pump is started to transport a small amount of water to the detection component 203 through the water inlet 206 to clean it.

[0037] The external starter allows air to enter the active cavity through the lifting air intake pipe 402, driving the lifting seat 404 and the mounting rod 405 to lift and move, thereby driving the extension frame 406 and the stirring plate 407 to rise to the corresponding height, and the stirring motor 301 is started again, and the extension frame 406 and the stirring plate 407 are driven to rotate by the rotation of the driving rod 303 to stir and mix the cement slurry at that position; when the detection result shows that there is too much solid raw material at multiple locations, liquid raw material is added from the liquid material pipe 5, and when the detection result shows that there is too much water at multiple locations, solid raw material is added from the feed port;

[0038] After the mixing is completed, the baffle is rotated to separate it from the hanging buckle 105, and the discharge plate is opened, and the mixing rod 304 is rotated to discharge the mixed cement from the discharge port.

Although the present invention has been disclosed as a preferred embodiment as above, it is not used to limit the present invention. Any technical personnel in this field can make some changes or modify the technical contents disclosed above into equivalent embodiments without departing from the scope of the technical solution of the present invention.
