DETAILED DESCRIPTION

[0025] The present invention will be further described below in conjunction with the accompanying drawings and embodiments.

[0026] Embodiment 1: A mortar preparation device capable of quantitative feeding, such as Figure 1-Figure 9As shown, a storage frame 101 is installed on the upper part of the bracket 1 by bolts, and the interior of the storage frame 101 is divided into two parts on the left and right by a partition. A discharge pipe 102 is symmetrically penetrated on the lower part of the storage frame 101, and a stirring mechanism 103 is installed on the front part of the bracket 1 by bolts. A quantitative unloading mechanism 2 is provided on the discharge pipe 102, and the quantitative unloading mechanism 2 includes a mounting plate 21, a motor 22, a first rotating shaft 23, a missing gear 24, a first turbine assembly 25, a second rotating shaft 26, a large gear 27 and a second turbine assembly 28. The discharge pipe 102 is connected to the mounting plate 21 by bolts, and the motor 22 is installed on the mounting plate 21 by bolts. The first rotating shaft 23 is rotatably connected to the discharge pipe 102 on the right, and the output shaft of the motor 22 is connected to the first rotating shaft 23 through a coupling. A missing gear 24 is fixedly connected to the rear part, and the distance of the missing part of the gear teeth on the missing gear 24 is set according to the mass multiple of the raw materials with a smaller specific gravity in the raw materials that need to be added. A first turbine assembly 25 is fixedly connected to the front part of the first rotating shaft 23, and the first turbine assembly 25 is located in the right discharge pipe 102, and the first turbine assembly 25 is rotatably matched with the right discharge pipe 102. A second rotating shaft 26 is rotatably connected to the left discharge pipe 102, and a large gear 27 is fixedly connected to the rear part of the second rotating shaft 26, and the large gear 27 is located on the left side of the missing gear 24, and the large gear 27 can mesh with the missing gear 24. A second turbine assembly 28 is fixedly connected to the front part of the second rotating shaft 26, and the second turbine assembly 28 is located in the left discharge pipe 102, and the second turbine assembly 28 is rotatably matched with the left discharge pipe 102.

[0027] When the device is to be used, the number of the moving gear teeth 35 to be reduced is determined according to the specific gravity of the raw materials to be used, and then the first baffle plate 32 is moved toward the missing gear 24 along the mounting rod 31, the first elastic member 33 is compressed, and at the same time, the pull rod 373 is pulled downward, the pull rod 373 will move the first connecting rod 371 downward, and when the first connecting rod 371 moves downward, it will move the fixing block 37 and the fixing rod 372 downward together. At this time, the first sliding rod 34 and the moving gear teeth 35 will also move downward together, the second elastic member 36 will be stretched, and the movement of the first baffle plate 32 will be stopped. The first elastic member 33 will rebound and reset with the first baffle plate 32. At this time, the first baffle plate 32 is located at Above the fixed rod 372, the upper part of the fixed rod 372 will contact the lower part of the first baffle 32. At this time, the first sliding rod 34 and the moving gear 35 are fixed, and the moving gear 35 is located inside the missing gear 24. If you want to continue to reduce the number of moving gears 35, repeat the above steps. When you want to increase the specific gravity of the part of the raw material with a smaller specific gravity, repeat the above steps and change the lower pull rod 373 to the upper pull rod 373. This allows the device to change the ratio of quantitative feeding according to different production needs, thereby improving the utilization rate and adaptability of the device; pour the raw materials to be used on the filter screen 7 respectively, and when preparing the mortar, The raw material with a larger specific gravity is poured onto the filter screen 7 on the right, and the raw material with a smaller specific gravity is poured onto the filter screen 7 on the right. The fine raw material will pass through the filter screen 7 and fall into the storage frame 101, and the larger raw material will remain on the filter screen 7. The raw material in the storage frame 101 will fall into the discharge pipe 102, thereby preventing larger raw material particles from entering the discharge pipe 102, causing the first turbine assembly 25 and the second turbine assembly 28 to be worn; the driving motor 22, the output shaft of the motor 22 will drive the first shaft 23 to rotate, the first shaft 23 will drive the missing gear 24 and the first turbine assembly 25 to rotate together, and when the first turbine assembly 25 rotates, it will drive the right The raw materials in the discharge pipe 102 are transported forward, and when the gear teeth on the waiting gear 24 contact and mesh with the large gear 27, the large gear 27 will be driven to rotate together. When the large gear 27 rotates, it will drive the second turbine assembly 28 to rotate together through the second rotating shaft 26. At this time, the second turbine assembly 28 will drive the raw materials in the left discharge pipe 102 to be transported forward, and when the gear teeth on the waiting gear 24 lose contact with the large gear 27, the large gear 27 stops rotating. This makes the raw materials transported by the first turbine assembly 25 and the raw materials transported by the second turbine assembly 28 in the same period of time have a multiple relationship, so that the device can realize automatic quantitative unloading without manual intervention.

[0029] like Figure 1 and Figure 7-Figure 9 As shown, it also includes a second slide bar 51, a cover plate 4 and a third elastic member 511. The second slide bar 51 is fixedly connected to the side where the right discharge pipe 102 and the left discharge pipe 102 are away from each other. The second slide bar 51 is slidably connected to the cover plate 4, and the cover plate 4 can fit with the discharge port of the discharge pipe 102. The third elastic member 511 is connected between the lower second slide bar 51 and the cover plate 4 through a spring seat.

[0030] like Figure 1 and Figure 7-Figure 9As shown, it also includes an auxiliary closing mechanism 5, a damper 6 and a filter screen 7. The cover plate 4 is provided with an auxiliary closing mechanism 5, and the auxiliary closing mechanism 5 includes a connecting plate 52, a hollow rod 53, a rotating rod 54, a propping rod 55, a second baffle 56, a second connecting rod 561, a third baffle 57 and a U-shaped plate 571. The sides of the cover plate 4 that are away from each other are fixedly connected with the connecting plate 52, and the bottom center position of the storage frame 101 is fixedly connected with a hollow rod 53, and the interior of the hollow rod 53 is rotatably connected with the rotating rod 54, and the front end of the rotating rod 54 is fixedly connected with the propping rod 55, and the initial state of the propping rod 55 is a vertical line shape, and the propping rod 55 is located between the two connecting plates. In the middle of the storage frame 101, a U-shaped plate 571 is connected to the bottom of the storage frame 101, and the U-shaped plate 571 is located above the third baffle 57; a damper 6 is installed on the side away from the right discharge pipe 102 and the left discharge pipe 102 by bolts; and filter screens 7 are respectively connected to the two parts in the storage frame 101.

[0031] When the output shaft of the motor 22 rotates, the second connecting rod 561 will also rotate together. When the second connecting rod 561 contacts the second baffle plate 56, the second connecting rod 561 continues to rotate, and the second baffle plate 56 will be driven by the second connecting rod 561 to rotate counterclockwise. When the second baffle plate 56 rotates, it will also drive the rotating rod 54 to rotate. At this time, the opening rod 55 and the third baffle plate 57 on the rotating rod 54 will also rotate together. When the opening rod 55 rotates, it will contact the connecting plate 52 and move it to the left and right. The connecting plate 52 will drive the cover plate 4 to move to the left and right along the second sliding rod 51, and the third elastic member 511 will be compressed. At the same time, the discharge port of the discharge pipe 102 will gradually be exposed. When the third baffle plate 57 contacts the U-shaped plate 571, the rotating rod 54 stops rotating, and the discharge port of the discharge pipe 102 is completely exposed. At this time, the opening rod 5 5 is in the shape of a horizontal horizontal line, which makes the raw materials transported by the first turbine assembly 25 and the second turbine assembly 28 fall into the stirring mechanism 103 from the discharge port, thereby realizing material discharge. When the second connecting rod 561 contacts the second baffle plate 56 again and rotates, the rotating rod 54 rotates with the components installed thereon. When the third baffle plate 57 contacts the other side of the U-shaped plate 571, the propping rod 55 is reset to a vertical line, and the third elastic member 511 rebounds with the connecting plate 52 to drive the damper 6. The damper 6 consumes the energy of the third elastic member 511 when it rebounds, thereby reducing the vibration and impact generated by the contact between the cover plate 4 and the discharge pipe 102 when it is reset, so that the cover plate 4 slowly fits with the discharge port, and the device temporarily stops discharging. The above steps are repeated to open and close the cover plate 4, thereby realizing quantitative discharging.
