DETAILED DESCRIPTION

Obviously, the described embodiments are only part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of this application.
[0019] See also Figure 1-3A water reducing agent pretreatment device comprises a pretreatment box 1, a box cover 2 is movably installed on the top of the pretreatment box 1, a discharge valve 3 is arranged at the bottom of the pretreatment box 1, a motor 4 is fixedly installed on the pretreatment box 1, a driving shaft 5 is fixedly connected to the output end of the motor 4, a rotating shaft 6 is rotatably connected to the end of the inner side of the pretreatment box 1 away from the driving shaft 5, a first end plate 7 is arranged on the rotating shaft 6 and the driving shaft 5, and a detachable stirring mechanism is arranged inside the pretreatment box 1.
[0020] Through the above technical solution, when the device is in use, the water reducing agent and part of the concrete are mixed and pretreated in the pretreatment box 1. During this period, the motor 4 is turned on to drive the drive shaft 5 to rotate, and the rotating shaft 6 is cooperated to rotate the stirring shaft 8, so that the stirring frame 10 can stir the mixture for pretreatment. After the pretreatment is completed, the mixture can be discharged from the discharge valve 3, and finally the detachable stirring mechanism can be removed to clean the inside of the pretreatment box 1.
[0021] Specifically, the detachable stirring mechanism includes a stirring shaft 8 arranged inside the pretreatment box 1 , a support rod 9 is fixedly connected to the outer surface of the stirring shaft 8 , and a stirring frame 10 is arranged at one end of the support rod 9 away from the stirring shaft 8 .
[0022] Through the above technical solution, several groups of support rods 9 are provided to stably support the stirring frame 10.
[0023] Specifically, both ends of the stirring shaft 8 are provided with second end plates 11 , and an arc plate 12 is provided inside the pretreatment box 1 .
[0024] Through the above technical solution, the second end discs 11 at both ends of the stirring shaft 8 and the first end discs 7 at the ends of the driving shaft 5 and the rotating shaft 6 are completely consistent in shape and size.
[0025] Specifically, a plate shaft 13 is fixedly penetrated through the inner side of the arc plate 12 , and there are two groups of plate shafts 13 , and the outer surfaces of the two groups of plate shafts 13 are rotatably connected with a first clamp frame 14 and a second clamp frame 15 , respectively.
[0026] Through the above technical solution, the first clamp frame 14 and the second clamp frame 15 can clamp the first end plate 7 and the second end plate 11 during the rotation along the plate shaft 13 .
[0027] Specifically, a frame shaft 16 is fixedly provided on the inner side of the first clamp frame 14 , and a screw rod 17 is rotatably connected to the outer surface of the frame shaft 16 .
[0028] Through the above technical solution, a groove is provided on the second clamp frame 15 so that the screw rod 17 can be embedded therein, while the butterfly cap 18 is too large to enter the groove.
[0029] Specifically, a butterfly cap 18 is threadedly sleeved on the outer surface of the screw rod 17 .
[0030] Through the above technical solution, the butterfly cap 18 can gradually move axially along the screw rod 17 during the screwing process until it is tightly pressed against the surface of the second clamp frame 15 to stably limit the second clamp frame 15.
[0031] Working principle: During the use of the water reducer pretreatment device, the stirring shaft 8, the driving shaft 5 and the rotating shaft 6 must be stably installed and connected first, that is, the first end plate 7 at the end of the driving shaft 5 and the second end plate 11 at one end of the stirring shaft 8 must be completely fitted and aligned, and then the first clamp frame 14 and the second clamp frame 15 must be rotated along the plate axis 13, so that the two sets of clamp frames are completely and tightly clamped on the outer surfaces of the two sets of end plates, and then the screw 17 is rotated along the frame axis 16, so that the screw 17 is embedded in the groove on the second clamp frame 15, and the butterfly cap 18 can be screwed. While the butterfly cap 18 rotates along the screw 17, it will gradually move axially until the butterfly cap 18 is tightly against the second clamp frame 15. At this time, the screw 17 is stably limited, so that the stirring shaft 8 is indirectly and stably connected to the driving shaft 5. Similarly, the other end of the stirring shaft 8 is stably connected to the rotating shaft 6, and then together with The mixing frame 10 is stably installed. During the pretreatment process, the water reducing agent and part of the concrete sample need to be placed in the pretreatment box 1. By turning on the motor 4, the drive shaft 5 is driven to rotate, thereby linking the stirring shaft 8 to rotate, and finally the mixing frame 10 stirs the mixture for pretreatment. During this period, the box cover 2 can be covered to reduce the evaporation of water in the pretreatment mixture under the scorching sun. After the pretreatment is completed, the mixture can be discharged from the discharge valve 3. When the pretreatment box 1 needs to be cleaned, the butterfly cap 18 can be unscrewed so that it does not limit the screw 17, so that the first clamp frame 14 and the second clamp frame 15 no longer stably limit the stirring shaft 8, so it can be easily removed. After the stirring shaft 8 and the mixing frame 10 are removed, the difficulty of cleaning the inside of the pretreatment box 1 can be greatly reduced, and at the same time, it will not touch the sharp parts, eliminating safety hazards.
