[0020] The present invention will be further described below with reference to the accompanying drawings.
[0021] according to Figure 1 As shown in Figure 4: This utility model provides a high-efficiency mixing and preparation device for multi-component cementitious materials: including a mixing mechanism 1; including a mixing box 2, the mixing box 2 is provided with a mixing cavity 201 with a top and bottom circular shape, and a hinged cover plate 202 on the top; the four corners of the mixing box 2 are respectively provided with support legs 203; a discharge pipe 204 communicating with the mixing cavity 201 is provided at one end of the mixing box 2, and a valve 205 is provided on the discharge pipe 204; the cover plate 202 and the valve 205 ensure that the raw materials do not escape when the device is mixing raw materials, so as not to affect the raw material ratio after mixing and the surrounding working environment;
[0022] according to Figure 3 , 4As shown: The upper sides of the mixing chamber 201 are connected to the rotary crushing mechanism 4 via negative pressure conveyors 3. The rotary crushing mechanism 4 includes a support plate 401 set on one side of the mixing chamber 2. Support rods 402 are provided at the four corners of the upper end of the support plate 401. A top plate 403 is provided above the four support rods 402. A rotary telescopic motor 404 with an output shaft passing through the top plate 403 is provided at the middle of the lower end of the top plate 403. A crushing block 405 is provided at the lower end of the output shaft of the rotary telescopic motor 404. Several elastic telescopic rods 406 are provided at the middle of the upper end of the support plate 401. A crushing barrel 407 with the upper part connected to the negative pressure conveyor 3 is provided at the upper end of the elastic telescopic rods 406. The crushing block 405 rotates and moves up and down in the crushing barrel 407. When the crushing block 405 is at the highest point of its movement range, the lower end face When the crushing block 405 is above the upper end face of the crushing barrel 407 and is in the middle of the movement range, its lower end face is on the same plane as the lower inner end face of the crushing barrel 407. When the crushing block 405 is at the lowest point of the movement range, the crushing block 405 drives the crushing barrel 407 to move downward, and the elastic telescopic rod 406 is in a retracted state. In this way, when the crushing block 405 is above the crushing barrel 407, the material can be put into the crushing barrel 407. Then, the rotary telescopic motor 406 is started, which will drive the crushing block 405 to rotate and move up and down. When the crushing block 405 contacts the material in the crushing barrel 407, it will apply pressure to the material and crush the material at the same time, thereby crushing the material. At the same time, the elastic telescopic rod 406 can cooperate with the crushing block 405 to move the crushing barrel 6 downward, thus protecting the crushing barrel 6.
[0023] according to Figure 1 , 2 As shown in Figure 4, the mixing mechanism 1 includes a stepper motor 101 disposed on one side of the mixing chamber 2. The output shaft of the stepper motor 101 passes through the end of the mixing chamber 2 and is provided with an electrically controlled push rod 102. The piston rod of the electrically controlled push rod 102 is provided with several mixing rods 103. In this way, by starting the stepper motor 101, the electrically controlled push rod 102 and several mixing rods 103 can be driven to rotate, thereby stirring the raw materials in the mixing chamber 201. At the same time, the cyclic extension and retraction 102 can change the position of several mixing rods 103, thereby improving the mixing efficiency.
[0024] according to Figure 2 , 4As shown: The piston rod of the electrically controlled push rod 102 is also equipped with an auxiliary mechanism 5; the auxiliary mechanism 5 includes connecting rods 501 arranged on both sides of the piston rod of the electrically controlled push rod 102, and the two connecting rods 501 are respectively connected to the two ends of the spiral scraper 502; the outer edge of the scraper 502 has the same diameter as the lower part of the mixing chamber 201; when the electrically controlled push rod 102 extends and retracts, the two ends of the scraper 502 respectively fit against the two ends of the mixing chamber 201; in this way, when the stepper motor 101 drives the electrically controlled push rod 102 to rotate, the scraper 502 connected by the connecting rods 501 will also rotate synchronously, which can also mix the raw materials. After the mixing is completed, the valve 205 is opened, the electrically controlled push rod 102 is retracted, and the stepper motor 101 is started. In this way, the scraper 502 will gradually push the raw materials to the discharge pipe 204, and then the electrically controlled push rod 102 is extended to discharge all the raw materials.
[0025] The principle of this utility model is as follows: When using the material, if the material is in block form, select an appropriate amount of material and put it into the crushing barrel 407. Then start the rotary telescopic motor 406. The rotary telescopic motor 406 will drive the crushing block 405 to rotate and move up and down. When the crushing block 405 comes into contact with the material in the crushing barrel 407, it will apply pressure to the material and crush the material at the same time to achieve crushing. After the material is crushed, start the negative pressure conveyor 3. The negative pressure conveyor 3 will transport the crushed material to the mixing chamber 201.
[0026] If the material is in powder form, select an appropriate amount of material and put it into the mixing chamber 201. Then cover the cover plate 202, start the stepper motor 101, and cycle the electric control push rod 102. The stepper motor 101 will drive the electric control push rod 102 and several mixing rods 103 to rotate, thereby stirring the raw materials in the mixing chamber 201. At the same time, the cyclic extension and retraction 102 can change the position of several mixing rods 103 to improve the mixing efficiency. After the mixing is completed, open the valve 205, retract the electric control push rod 102, and start the stepper motor 101. In this way, the scraper 502 will gradually push the raw materials towards the discharge pipe 204. Then, the electric control push rod 102 will be extended to discharge all the raw materials.
[0027] If the proportion of materials needs to be changed during mixing, the materials are placed in the crushing bucket 407, and then the negative pressure conveyor 3 is started. The negative pressure conveyor 3 will transport the crushed materials to the mixing chamber 201.
[0028] This prevents the material from escaping during mixing and also allows for the crushing of raw materials. Raw materials can also be added during mixing. The auxiliary mechanism 5 can both improve mixing efficiency and assist in material discharge.
[0029] The present invention and its embodiments have been described above. This description is not restrictive, and the accompanying drawings are only one embodiment of the present invention; the actual structure is not limited thereto. In conclusion, if those skilled in the art are inspired by this description and design similar structures and embodiments without departing from the inventive spirit of the present invention, such designs should fall within the protection scope of the present invention.
