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.
[0027] The utility model provides a technical solution:
[0028] See also Figures 1 to 5 A concrete pouring device includes a concrete pump truck body 1, a material shaking component 2 is provided inside the upper side of the concrete pump truck body 1, the material shaking component 2 includes a placement groove 21 opened inside the upper side of the concrete pump truck body 1, a storage box 22 is slidably overlapped inside the placement groove 21, and a screening component 3 is provided inside the storage box 22;
[0029] A driving motor 23 is arranged inside the concrete pump truck body 1, and one end of the output shaft of the driving motor 23 is fixedly connected to a transmission unit 24, which is arranged in the inner cavity of the concrete pump truck body 1. Two connecting shafts 25 are fixedly connected to the right side of the transmission unit 24, and triangular cams 26 are fixedly connected to the outer sides of the two connecting shafts 25. Two extrusion grooves 27 are provided at the bottom end of the storage box 22, and the outer surfaces of the two triangular cams 26 are rotatably overlapped with the bottom end of the same storage box 22 through the extrusion grooves 27. An active cavity 28 is provided on the right side of the placement groove 21, and a buffer assembly 29 is provided on the lower side of the concrete pump truck body 1.
[0030] The shape of the placement groove 21 is adapted to the shape of the storage box 22 . A hose-transported concrete pump is arranged in the concrete pump truck body 1 . The placement groove 21 is connected to the movable cavity 28 . The right side of the storage box 22 is connected to the hose, and the hose moves inside the movable cavity 28 .
[0031] The transmission unit 24 is composed of two transmission wheels and a transmission belt sleeved on the outside of the two transmission wheels. The ends of the two connecting shafts 25 close to the transmission unit 24 are respectively located at the center of the two transmission wheels close to the connecting shafts 25.
[0032] The buffer assembly 29 includes four fixed cylinders 291 fixedly connected to the bottom end of the concrete pump truck body 1, and the four fixed cylinders 291 are all connected to the placement groove 21. The bottom end of the storage box 22 is fixedly connected to four piston rods 292, and the four piston rods 292 are slidably connected in the four fixed cylinders 291 respectively.
[0033] The bottom end of the fixed cylinder 291 is fixedly connected with an air outlet pipe 293, which is communicated with the fixed cylinder 291. The cross-sectional diameter of the lower half of the piston rod 292 is the same as the cross-sectional diameter of the inner cavity of the fixed cylinder 291, and the cross-sectional diameter of the inner cavity of the fixed cylinder 291 is larger than the cross-sectional diameter of the inner cavity of the air outlet pipe 293.
[0034] By adopting the above technical solution, first, the concrete pump truck body 1 can be moved by its own driving device. After reaching the construction area, since the storage box 22 inside the placement slot 21 is connected to the concrete pump truck body 1 through a hose, the storage box 22 can move up and down slightly in the placement slot 21. Then, when the drive motor 23 is started, one of the transmission wheels in the transmission unit 24 is connected to the drive motor 23, so that the output shaft of the drive motor 23 rotates and drives this transmission wheel to rotate. At the same time, the transmission belt outside this transmission wheel will drive another transmission wheel to rotate, so that the two transmission wheels synchronously drive the two connecting shafts 25 to rotate inside the placement slot 21. During the rotation of the two connecting shafts 25, the two triangular cams 26 fixed on the outside of the two connecting shafts 25 will repeatedly contact the two extrusion grooves 27 below the storage box 22, and the storage box 22 is repeatedly lifted;
[0035] When concrete is poured into the storage box 22, since part of the hose is in the movable cavity 28, the aggregate nodules stuck to the inner wall of the storage box 22 and the inner wall of the hose will be shaken apart and fall off. During the up and down movement of the storage box 22, the piston rod 292 below the storage box 22 will move inside the fixed cylinder 291. When the piston rod 292 moves upward, the outside air will be drawn into the fixed cylinder 291 through the air outlet pipe 293. When the piston rod 292 moves downward, since the inner cavity diameter of the air outlet pipe 293 is smaller than the inner cavity diameter of the fixed cylinder 291, the air inside the fixed cylinder 291 will be slowly discharged and the storage box 22 will be buffered. Since the storage box 22 is repeatedly lifted by the cam, the concrete inside the storage box 22 will be repeatedly bumped to prevent the concrete from sticking to the inner wall of the storage box 22 and the inner wall of the hose, thereby ensuring the normal transportation of concrete, and the multiple aggregates bonded by the high-viscosity concrete will also be shaken apart to prevent the concrete from being blocked in the hose and causing the hose to rupture.
[0036] Specifically, Figure 4 and Figure 5 As shown, the screening component 3 includes two guide grooves 31 opened on both sides of the storage box 22, and guide blocks 32 are slidably connected in the two guide grooves 31. The upper and lower sides of the two guide blocks 32 are fixedly connected with columns 33, and four columns 33 are slidably connected in the two guide grooves 31 respectively.
[0037] A return spring 34 is sleeved on the outer side of the column 33 , and one end of the opposite surface of two adjacent return springs 34 is fixedly connected to the upper and lower sides of the guide block 32 , and one end of the two adjacent return springs 34 that is away from each other is overlapped on the upper and lower sides of the guide groove 31 .
[0038] The inner cavity of the storage box 22 is slidably connected with a sieve plate 35 , and the two guide blocks 32 are fixedly connected to one side of the opposite surface with baffles 36 . The two baffles 36 are fixedly connected to the two sides of the sieve plate 35 on one side of the opposite surface, and the two baffles 36 cover the two guide grooves 31 .
[0039] By adopting the above technical solution, first, in the process of the storage box 22 being lifted upward, the sieve plate 35 inside the storage box 22 will be subjected to the upward impact force and move upward, and the guide blocks fixed on both sides of the sieve plate 35 will also slide with the sieve plate 35 in the two guide grooves 31, and the columns 33 above the guide blocks will enter the depth of the guide grooves 31, and then after the storage box 22 moves downward, the sieve plate 35 begins to descend according to its own weight. At the same time, the two return springs 34 on the upper and lower sides of the guide blocks will accelerate the movement of the guide blocks. At the same time, the return spring 34 under the guide blocks will prevent the guide blocks from directly colliding with the side wall below the guide groove 31. At the same time, the baffles 36 on both sides of the sieve plate 35 will block the guide groove 31. Since the storage box 22 drives the repeated up and down movement, the aggregate nodules screened by the sieve plate 35 will also shake when screened by the sieve plate 35, and the shaken aggregate will re-enter the depth of the storage box 22, avoiding the waste of concrete, and also preventing the aggregate nodules from solidifying above the sieve plate 35.
[0040] Working principle: First, the concrete pump truck body 1 drives itself to the construction area. When the concrete is poured into the storage box 22, the drive motor 23 can be started to drive the transmission unit 24 to rotate, so that the transmission unit 24 can simultaneously drive the two connecting shafts 25 and the triangular protrusions on the outside to rotate. After the protruding end of the triangular cam 26 enters the extrusion groove 27, the storage box 22 will be lifted in the placement groove 21. At this time, the hose connected to the concrete pump truck body 1 will move in the movable cavity 28. As the storage box 22 is repeatedly lifted, the movable cavity 28 below the storage box 22 The plug rod 292 will also move up and down inside the fixed cylinder 291. Since the inner diameter of the fixed cylinder 291 is larger than the inner diameter of the air outlet pipe 293, the air drawn into the fixed cylinder 291 during the rising process will be slowly discharged when the storage box 22 descends. At the same time, the sieve plate 35 will also move up and down with the storage box 22, and shake the aggregate nodules staying above the sieve plate 35. The guide blocks on both sides of it also always move inside the guide groove 31, and increase the fluctuation amplitude through the return spring 34 on the outside of the column 33, and the baffles 36 on both sides of the sieve plate 35 will always block the guide groove 31.
[0041] Finally, it should be noted that the above embodiments are only used to illustrate the technical solution of the utility model, rather than to limit it. Although the utility model has been described in detail with reference to the aforementioned embodiments, ordinary technicians in this field should understand that they can still modify the technical solutions recorded in the aforementioned embodiments, or replace some or all of the technical features therein with equivalents. However, these modifications or replacements do not make the essence of the corresponding technical solution deviate from the scope of the technical solution of the embodiments of the utility model.
