[0013] Compared with the prior art, the beneficial effects of the utility model are:
[0014] The utility model discloses an underwater concrete pouring anti-clogging hopper device. When the hopper device is used for underwater concrete pouring, clogging is usually easy to occur. By rotating the hoist wire rope, the bottom sealing disc can seal the disc positioning device, and concrete is poured at the same time, so that the concrete can be filtered by the filter screen, thereby preventing a large number of block impurities in the concrete from clogging the hopper body. In addition, the disc positioning device is first sealed by the bottom sealing disc, so that concrete can be accumulated in the hopper body. After the bottom sealing disc is pulled up by the hoist wire rope, the accumulated concrete can directly fall into the conduit, thereby preventing the hopper device from being blocked and piles from being broken when pouring concrete.

[0021] Embodiment 1
[0022] See also Figures 1 to 4 The utility model provides a technical solution: an underwater concrete pouring anti-blocking hopper device, comprising a hopper body 1, a lifting ear 2, a disc positioning device 3, a bottom disc 4 and a filter screen 5, the top of the hopper body 1 is provided with a lifting ear 2, the side of the hopper body 1 away from the lifting ear is provided with a disc positioning device 3, the side of the hopper body 1 close to the disc positioning device 3 is provided with a bottom disc 4, the top of the hopper body 1 is provided with a filter screen 5 on the side close to the lifting ear 2, the filter screen 5 is provided with a filter screen hanging buckle 6 on one side of the filter screen 5, and the side of the hopper body 1 close to the filter screen hanging buckle 6 is provided with symmetrically distributed steel pipes 7, the surface of the bottom disc 4 is connected with a manual hoist 8, the side of the manual hoist 8 away from the bottom disc 4 is connected with a hoist wire rope 9, and the top of the filter screen 5 is provided with a concrete baffle 10.
[0023] Embodiment 2
[0024] On the basis of Example 1, in order to prevent the inside of the hopper device from being blocked, the bottom disc 4 can be rotated by rotating the hoist wire rope 9 to seal the disc positioning device 3, and at the same time, concrete is poured so that the concrete can be filtered by the filter net 5 to prevent more block impurities inside the concrete from blocking the hopper body 1. First, the disc positioning device 3 is blocked by the bottom disc 4, so that the concrete can accumulate inside the hopper body 1, so that after the bottom disc 4 is pulled up by the hoist wire rope 9, the accumulated concrete can directly fall into the conduit, thereby preventing the hopper device from being blocked when pouring concrete.
[0025] At the same time, when pouring with accumulated concrete, it can prevent the concrete from being buried below 1.0m at the bottom of the conduit, so that broken piles can be avoided when the hopper device pours concrete into the inside of the conduit, making the hopper device more convenient during pouring.
[0026] The side of the filter hook 6 away from the filter 5 is connected to a fixing seat 11, a transverse plate 12 is arranged inside the fixing seat 11, one side of the transverse plate 12 is connected to a pull ring 13, the side of the transverse plate 12 away from the pull ring 13 is connected to an insertion rod 14, a limiting spring 15 is connected to the surface of the insertion rod 14, and a symmetrically distributed locking groove 16 is provided on the side of the steel pipe 7 close to the insertion rod 14.
[0027] Embodiment 3
[0028] On the basis of Example 2, in order to achieve stability during filling, the pull ring 13 is pulled so that the pull ring 13 can move the connected cross plate 12, so that the cross plate 12 can move the insertion rod 14 when moving, and at the same time, the insertion rod 14 can squeeze the limiting spring 15 connected to the surface when moving, so that the insertion rod 14 can be separated from the steel pipe 7 when moving, so that the filter screen 5 can be moved to a suitable position. Conversely, the pull ring 13 is loosened, so that the limiting spring 15 can push the cross plate 12 and the insertion rod 14 after resetting, so that the insertion rod 14 can be locked with the locking groove 16, so that the filter screen 5 can be more stable during filtering, thereby making the hopper device more stable during pouring.
[0029] In actual use, the project pile foundation engineering is large in volume, short in construction period, high in construction quality requirements, and a large number of pile foundation inspections. At least one pile foundation must be inspected under each pedestal. Therefore, the pile foundation is operated through the hopper device during processing. By rotating the hoist wire rope 9, the bottom disc 4 can seal the disc positioning device 3, and at the same time, concrete is poured so that the concrete can be filtered by the filter net 5 to prevent the hopper body 1 from being blocked by a large number of block impurities inside the concrete. First, the disc positioning device 3 is sealed by the bottom disc 4, so that the concrete can accumulate inside the hopper body 1, so that after the bottom disc 4 is pulled up by the hoist wire rope 9, the accumulated concrete can directly fall into the conduit, thereby avoiding blockage and broken piles when the hopper device is pouring concrete.
