Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0022] Example 1

[0023] Please see Figure 1 The figure shows a concrete pouring hopper, including a pouring hopper shell 1. A fixing frame 2 is fixedly installed on the outside of the pouring hopper shell 1. The top of the fixing frame 2 is provided with multiple connecting holes 3. A connecting ring 4 passes through the inside of the connecting holes 3. A connector 5 passes through the inside of the connecting ring 4. A connecting base 6 is provided on the side of the connector 5 away from the connecting ring 4. A buckle ring 7 is fixedly installed on the outside of the connecting base 6. A movable buckle 8 is provided on the outside of the connecting base 6. A hanging ring 9 is fixedly installed on the top of the connecting base 6. An inner liner 10 is inserted into the top of the pouring hopper shell 1. A limit groove 11 and a limit groove 2 are provided at the bottom of the outer edge of the inner liner 10. A discharge switch assembly 13 is fixedly installed at the bottom of the pouring hopper shell 1.

[0024] The discharge switch assembly 13 includes a protective shell 1301, a drive bar 1302, a pull ring 1303, a stop plate 1304, a spring 1305, a protrusion 1306, a first fixed shaft 1307, a first gear 1308, a second fixed shaft 1309, a second gear 1310, and a baffle 1311. The drive bar 1302 is slidably connected to the inner side of the protective shell 1301. The pull ring 1303 is fixedly installed on the side of the drive bar 1302 away from the outer shell 1 of the pouring hopper. Stop plates 1304 are provided on the left and right sides of the drive bar 1302. A spring 1305 is fixedly installed on the side of the abutment plate 1304 away from the outer shell 1 of the pouring hopper. Multiple protrusions 1306 are provided on the left and right sides of the drive bar 1302. A fixed shaft 1307 is fixedly installed on the inner side of the protective shell 1301. A gear 1308 is rotatably connected to the outer side of the fixed shaft 1307. A fixed shaft 2 1309 is fixedly installed on the inner side of the protective shell 1301. A gear 2 1310 is rotatably connected to the outer side of the fixed shaft 2 1309. A baffle 1311 is fixedly installed at the bottom of the gear 2 1310.

[0025] Please see Figure 1-5 As shown in the figure, there are multiple connectors 5, and a snap ring 7 is provided through one side of each connector 5 away from the connecting ring 4.

[0026] In this embodiment: the connecting piece 5 is connected to the connecting ring 4 on one side, and the side of the connecting piece 5 away from the connecting ring 4 is then fastened to the buckle ring 7, so that one side of the connecting piece 5 can be fixedly connected to the connecting base 6. At the same time, the setting of multiple connecting pieces 5 also improves the stability of the overall structure.

[0027] Working principle: Insert the outer edge of the outer shell 1 of the pouring hopper into the limiting groove 11, and simultaneously insert the fixing bracket 2 into the limiting groove 12. This fixes the inner liner 10 inside the outer shell 1 of the pouring hopper. It can also be disassembled and replaced later. By connecting one side of the connecting piece 5 to the connecting ring 4, and then fastening the side of the connecting piece 5 away from the connecting ring 4 into the buckle ring 7, and resetting the movable buckle 8 in the opposite direction, one side of the connecting piece 5 can be fixedly connected to the connecting base 6. Then, the pouring hopper can be lifted by the hanging ring 9 at the top. At this time, connect the rope to the pull ring 1303 on the side of the drive bar 1302 away from the protective shell 1301, and then pull the rope towards the side away from the protective shell 1301. Pulling the rope in one direction causes the drive bar 1302 to move toward the pull ring 1303. At this time, the spring 1305 deforms under force, causing the gear 1308 to rotate. In conjunction with the gear 2 1310, the baffle 1311 rotates about the gear 2 1310, thereby opening the discharge port. When the rope is released or a certain length of rope is loosened, the spring 1305 is reset by the reaction force, moving away from the pull ring 1303. This causes the abutment 1304 to drive the drive bar 1302 to move away from the pull ring 1303, resetting the drive bar 1302. The baffle 1311 also rotates in the opposite direction with the gear 2 1310, thereby closing the discharge port.

[0028] Example 2

[0029] Please see Figure 1-5 This embodiment further illustrates Example 1. In the figure, one side of the movable buckle 8 is attached to one side of the buckle ring 7, and the movable buckle 8 and the connecting base 6 are rotatably connected.

[0030] In this embodiment: by setting the movable buckle 8, when one side of the connector 5 is fastened into the inner side of the buckle ring 7, one side of the connector 5 squeezes the movable buckle 8, causing the movable buckle 8 to rotate towards the inner side of the buckle ring 7. When one side of the connector 5 is fastened into the inner side of the buckle ring 7, the squeezing force disappears, and the movable buckle 8 resets in the opposite direction, thereby locking and limiting one side of the connector 5, making it difficult for the connector 5 to leave the inner side of the buckle ring 7 during use, improving stability, and preventing the pouring bucket from tipping over and affecting construction.

[0031] Please see Figure 1-5 In the diagram, the limiting groove 11 is plugged into the outer edge of the casting hopper shell 1, and the limiting groove 2 is plugged into the fixing frame 2.

[0032] In this embodiment: by setting the limiting groove 11, after the outer edge of the casting hopper shell 1 is inserted into the limiting groove 11, the inner liner 10 can be fixed inside the casting hopper shell 1 and will not shift in the horizontal direction. At the same time, the fixing bracket 2 is inserted into the limiting groove 12, so that the inner liner 10 will not rotate along the outer edge of the casting hopper shell 1 when it is inside the casting hopper shell 1, so that the inner liner 10 is further fixed inside the casting hopper shell 1, improving the stability of the overall structure.

[0033] Please see Figure 1-5 In the figure, the inner liner 10 is located inside the outer shell 1 of the casting hopper, and the outer side of the inner liner 10 is tightly fitted to the inner side of the outer shell 1 of the casting hopper.

[0034] In this embodiment: With the inner liner 10 provided, after construction is completed, the inner liner 10 can be removed for cleaning and maintenance, extending the service life of the inner liner 10. At the same time, the interior of the pouring hopper is often subject to irreversible influence and damage during construction. The replaceable inner liner 10 improves the service life of the overall structure and enhances practicality.

[0035] Please see Figure 1-5 In the figure, the side of the spring 1305 away from the abutment 1304 is fixedly installed with the protective shell 1301, and the drive bar 1302 passes through one side of the protective shell 1301 and extends to the inside of the protective shell 1301.

[0036] In this embodiment: A spring 1305 is used to connect the rope to the pull ring 1303 on the side of the drive bar 1302 away from the protective shell 1301. Pulling the rope in the direction away from the protective shell 1301 causes the drive bar 1302 to move towards the pull ring 1303. At this time, the spring 1305 is deformed by force. When the rope is released or a certain length of rope is loosened, the spring 1305 is reset by the reaction force towards the side away from the pull ring 1303. This causes the abutment 1304 to drive the drive bar 1302 to move towards the side away from the pull ring 1303, thus resetting the drive bar 1302. This allows for remote control, ensuring the personal safety of the staff under certain circumstances and making the operation more convenient.

[0037] Please see Figure 1-5 In the diagram, the drive bar 1302 is meshed with gear 1308 via protrusion 1306, and gear 1308 is meshed with gear 2 1310.

[0038] In this embodiment: When the drive bar 1302 is pulled away from the outer shell 1 of the pouring hopper, the gear 1308 rotates, cooperating with the gear 2 1310, causing the baffle 1311 to rotate about the gear 2 1310, thereby opening the discharge port. When the drive bar 1302 returns to its original position, the baffle 1311 rotates in the opposite direction with the gear 2 1310, thereby closing the discharge port. The opening and closing angle of the baffle 1311 can be controlled by the movement distance of the drive bar 1302, thereby controlling the flow rate during discharge, making the operation more precise, and avoiding excessive concrete in the pouring hopper and thus preventing waste.
