Technical Field

[0002] Cement paste mixer is a device used to mix cement and water into uniform test paste. It is mainly used to measure cement standard consistency, setting time and make stability test blocks. In the existing concrete slurry mixing test process, cement, water and aggregate are usually added into a mixing pot simultaneously for mixing. During mixing, due to insufficient dispersion of cement and incomplete hydration reaction, more pores and defects may be formed inside the concrete, affecting the compactness of the concrete. In addition, uneven mixing is prone to occur, which may lead to poor workability of the concrete mixture, such as unstable slump, poor cohesion and water retention, etc. When adding raw materials in batches during the mixing process, it is necessary to stop the machine and remove the mixing pot to complete the operation, which is very inconvenient. The time spent will cause the concrete to have a slight drying phenomenon, which is not conducive to the concrete paving test. Therefore, it needs to be improved. Summary of the invention

[0020] See also Figure 1 , Figure 2 , Fig.10 , Fig.11 , this embodiment provides a technical solution: The paving mechanism 9 includes a motor 901, the output end of the motor 901 is rotatably connected to a bevel gear rod 902, the side of the bevel gear rod 902 is meshed with a bevel gear rod 903, the axis of the bevel gear rod 903 is fixedly connected to a reciprocating screw rod 904, the reciprocating screw rod 904 is rotatably connected to the swing table 4, the reciprocating screw rod is threadedly connected to a push seat 905, and the top of the push seat 905 is slidably connected to the swing table 4; The inner side surface of the swing table 4 is symmetrically provided with a middle guide bar 906, which is arranged in a hook shape, and one end is arranged as an inclined surface. The vertical dimension of the middle guide bar 906 is smaller than the dimension of the middle part of the I-shaped base 13, and its function is to facilitate the downward rotation of the stirring pot 5. The bottom end of the middle guide bar 906 is slidably connected to the limit rod 907; In this embodiment, both sides of the push seat 905 and the swing table 4 near the push seat 905 are inclined surfaces, which facilitates the smooth placement of the I-shaped base 13 on the push seat 905; In this embodiment, after paving the concrete, the limiting rod 907 can be pulled out to the side to remove the I-shaped base 13 from the swing table 4, or the mixing pot 5 can be rotated upward to move the I-shaped base 13 back; The use method and advantages of the present invention: The automatic discharging type cement slurry mixer for concrete processing has the following working process: like Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5 , Figure 6 , Figure 7 , Figure 8 , Fig. 9 , Fig.10 , Fig.11 As shown: S1: before mixing, cement, water and other mixtures for cement mixing are added into the mixing pot 5, and then the mixing pot 5 is placed on the side of the platform 4 close to the clamping plate 706, the clamp head 12 on the mixing pot 5 is clamped into the bayonet 704, the I-shaped base 13 at the bottom of the mixing pot 5 is in contact with the push seat 905, and then the aggregate for concrete processing is evenly laid into the retaining ring 803, and then the motor 701 is started to drive the reciprocating screw rod 702 to move the lifting frame 703 upward. During the process, the lifting frame 703 drives the mixing pot 5 vertically through the bayonet 704. The lifting frame 703 is lifted up, and the crossbar 705 and the clamping plate 706 installed at the bottom of the lifting frame 703 move upward synchronously. According to the trajectory set by the guide groove 11, the two clamping plates 706 are subjected to the pressure of the spring during the upward movement, and the trajectory direction of the guide groove 11, and the two clamping plates 706 move closer to the center, clamping the middle part of the I-shaped base 13 in the process, completing the clamping and limiting of the mixing pot 5, and being in a vertical position according to the trajectory direction above the guide groove 11. This state continues. When the stirring shaft 3 is immersed in the interior of the stirring pot 5, the stirring device 2 is started to stir the cement; S2: When the cement mixing is completed, the mixing device 2 is stopped, and the motor 1 701 is started to make the reciprocating screw 1 702 drive the lifting frame 703 to move downward. During the process, the toothed plate 708 fixedly connected to the lifting frame 703 drives the gear 1 710 and the gear 2 711 to rotate, and the gear 2 711 drives the connecting shaft 712 to rotate to rotate the lever 713 and the lever 713. When the lever 713 rotates, it contacts the stopper 715 and conflicts with it. When the connecting shaft 712 rotates, it drives the inner rotating disk 719 to rotate synchronously. Under the pressure of the spring sheet 720, the top rod 721 and the wheel disc 714 open When the belt 716 is wound, the push plate 726 is pulled on the mounting rod 724 to slide horizontally, and the spring 3 725 is compressed during the process. When the push plate 726 passes under the stopper 813, the stopper 813 is pushed upward. After passing the stopper 813, the stopper 813 automatically falls. At this time, the I-shaped base 13 falls on the push seat 905, and the lever 713 passes through the inclined block 723, so that the lever 713 is squeezed outward and pushed out. 713 compresses spring 2 718, motor 1 701 stops working, lever 713 moves completely from between inner turntable 719 and connecting shaft 712 to connecting shaft 712, does not contact inner turntable 719, and lever 713 and stopper 715 are disconnected, spring 3 725 is quickly released, push plate 726 pushes stopper 813 to move forward, stopper 813 drives bracket 801 to move synchronously, during which stopper ring 803 and meniscus 804 carry aggregate to move above stirring pot 5, and when approaching, round rod 814 fixedly connected to the top of stopper 813 contacts wedge The head rod 727 is pressed upward by the wedge rod 727, so that the connection between the stopper 813 and the push plate 726 is disconnected, and the push plate 726 automatically returns to its original position. During the process, the retracting plate 811 contacts the blocking rod 812, so that the spring 810 is squeezed, and the end of the plug rod 809 is separated from the inside of the through hole 808. The aggregates on the two menisci 804 press the menisci 804 down due to gravity, and the two menisci 804 rotate downward with the central axis 802 as the axis, and the aggregates fall evenly into the mixing pot 5. After the aggregates are all dropped, the electric push rod 14 is started, and the electric push rod 14 pushes the bracket 801 back to its original position; S3: Then continue to start the motor 701 to move the mixing pot 5 upward again. During the process, the inner turntable 719 reverses, causing the push rod 721 to leave the tooth opening 722, enter the next tooth opening 722, and leave again, so that the inner turntable 719 will not drive the wheel 714 to reverse during its rotation. After the mixing pot 5 reaches the high position, stop the motor 701, start the mixing device 2, mix the aggregate and cement in the mixing pot 5, and process them into concrete. After the processing is completed, stop the mixing device 2, start the motor 701, and drive the mixing pot 5 to move down to the low position. After reaching the low position , stop motor 1 701, the clamping plate 706 automatically releases the I-shaped base 13, start motor 2 901, rotate the reciprocating screw rod 2 904, and push the I-shaped base 13 outward through the push seat 905. During the process, the middle gap of the I-shaped base 13 is stuck in the median guide bar 906. When it reaches the other side of the median guide bar 906, the stirring pot 5 rotates downward, and finally the I-shaped base 13 contacts the limiting rod 907, so that the opening of the stirring pot 5 faces obliquely downward, and the concrete in the stirring pot 5 is automatically poured onto the flat table 10 and spread out, completing the automatic paving of the concrete.
