DETAILED DESCRIPTION

[0020] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0021] See also Figure 1-4 A concrete slump detection device includes a base 1 and a lifting mechanism 20. Fixed frames 8 are provided on both sides of the base 1. Fixed blocks 7 are fixedly installed on the sides of the fixed frame 8. The ends of the fixed blocks 7 are fixedly connected to racks 6. The lifting mechanism 20 controls the slump cone 2 to rise and fall. A connecting rod 3 is fixedly connected to the side of the slump cone 2. One end of the connecting rod 3 is rotatably connected to a lifting block 4. The other end of the connecting rod 3 is fixedly connected to a gear 5. There is a gap between the gear 5 and the rack 6. During the upward movement of the slump cone 2, the gap between the gear 5 and the rack 6 gradually decreases, and the gear 5 is meshed with the rack 6. The lifting block 4 is slidably connected to the fixed frame 8.

[0022] Among them, a stirring mechanism 21 is arranged on the top of the collapse cone 2, and the stirring mechanism 21 includes a connecting frame 9, a movable plate 10, a rotating motor 12, a rotating rod 13 and a stirring rod 14. The end of the connecting frame 9 is fixedly connected to the outer surface of the collapse cone 2, and both ends of the movable plate 10 are fitted with the inner wall of the connecting frame 9. The bottom of the rotating motor 12 is fixedly installed on the top of the movable plate 10, and the output shaft of the rotating motor 12 passes through the movable plate 10. One end of the rotating rod 13 is fixedly connected to one end of the output shaft of the rotating motor 12, and the outer surface of the stirring rod 14 is fixedly installed on the inside of the rotating rod 13. During the operation of the stirring mechanism, the bubbles in the concrete inside the collapse cone 2 can be effectively removed, so that the concrete as a whole becomes more compacted, and the slump of the concrete can be detected more accurately.

[0023] Among them; the lifting mechanism 20 includes a mounting frame 15, a worm 16, a worm wheel 17 and a threaded rod 18. The bottom of the mounting frame 15 is fixedly installed with the top of the side of the base 1, the end of the worm 16 is connected to the inside of the mounting frame 15, the worm wheel 17 is meshed with the worm 16, the threaded rod 18 is coaxially fixedly connected with the worm wheel 17, and the threaded rod 18 passes through the bottom of the fixed frame 8, and the threaded rod 18 passes through the lifting block 4 and is threadedly connected with the lifting block 4. During the operation of the lifting mechanism, the collapse cone 2 can be smoothly removed from the outside of the concrete, and will not cause bumps to the concrete pile during the removal process, thereby effectively ensuring the integrity of the concrete pile. After the collapse cone is lifted by the lifting mechanism, the worm and worm wheel therein can prevent the collapse cone from being affected by the gravity of the mixing mechanism, thereby causing the phenomenon of falling, and can play a role in limiting the height of the collapse cone.

[0024] In some more specific embodiments, even if the driving mechanism of the drive 16 is not shown in the drawings of the present application, technicians skilled in the art should know that the end of the worm 16 can extend from the mounting frame 15 to be connected to the rotating handle to manually control the rotation of the worm 16, or a driving motor can be installed on the top of the side 1 to realize the rotation of the worm 16.

[0025] Wherein, both ends of the movable plate 10 are plugged with a limit pin 11, and one end of the limit pin 11 passes through the connecting frame 9.

[0026] The bottom of the threaded rod 18 is rotatably connected to a fixed sleeve shaft 19, and the bottom of the fixed sleeve shaft 19 is fixedly installed with the top of the side of the base 1.

[0027] Among them, the outer surface of one end of the threaded rod 18 fits with the inner wall of the bottom of the fixed frame 8, and the connecting frame 9 is U-shaped as a whole.

[0028] Among them, the material of the collapse cone 2 is iron.

[0029] Working principle: when in use, the operator first pours concrete into the slump cone 2, then adjusts the height of the movable plate 10 inside the connecting frame 9, and after it reaches a suitable position, the rotating rod 13 is extended into the slump cone 2, and then two sets of limit pins 11 are respectively passed through the two ends of the movable plate 10, so as to form a limit on the movable plate 10, so that the rotating rod 13 and the stirring rod 14 inside the rotating rod 13 are rotated by the rotation of the output shaft of the rotating motor 12, so as to stir the concrete inside the slump cone 2, so as to eliminate the cavity bubbles inside the concrete pile and make its structure dense. The worm 16 is then driven to rotate by an external power source, so that the meshing worm wheel 17 and the threaded rod 18 connected to the inner wall of the worm wheel 17 rotate, and when the threaded rod 18 rotates, the lifting block 4 can be effectively controlled to move up and down along the inner wall of the fixed frame 8, so that the collapse cylinder 2 is lifted to demould the concrete, and when the height of the bottom of the collapse cylinder 2 exceeds the height of the concrete to the top, the gear 5 is meshed with the rack 6. At this time, the rotating gear 5 will drive the collapse cylinder 2 to flip to the outside of the base, thereby avoiding the collision of the cylinder with the concrete to cause its deformation and facilitating the observation of the slump of the concrete.
