An anti-deviation rod 211 connected to the bottom plate 1 is installed on the inner wall of the top of the support frame 201, and the lifting plate 202 is slidably sleeved on the outside of the anti-deviation rod 211. The ear plate 210 is fixedly installed on the outer wall of the collapse cylinder 5, and a long rod 209 connected to the ear plate 210 is fixedly installed on the outer wall of one side of the lifting plate 202.

[0026] In specific implementations, such as Figure 1 , 3 and Figure 4 As shown, a hopper 3 is placed on the top of the slumping cylinder 5, and a connecting assembly 4 is provided on the outer wall of the slumping cylinder 5. The connecting assembly 4 includes a fixing frame 401, a connecting block 402 and a moving plate 404. The connecting assembly 4 is used to fix the hopper 3 to the top of the slumping cylinder 5.

[0027] Furthermore, the fixing frame 401 is installed on the outer wall of the slumping cylinder 5, and the connecting block 402 is installed on the outer wall of the hopper 3. The connecting block 402 has a slot 403 inside.

[0028] Furthermore, both ends of the fixing frame 401 are provided with connecting grooves 406, and connecting blocks 402 are inserted into the connecting grooves 406. The fixing frame 401 and connecting blocks 402 are used to fix the hopper 3 and the slumping cylinder 5.

The spring 409 is sleeved on the outside of the connecting rod 407, and the elastic force of the spring 409 can push the movable plate 404 to move.

[0031] Furthermore, the fixed frame 401 is provided with a limiting rod 410 inside, and the movable plate 404 is slidably sleeved on the outside of the limiting rod 410. The limiting rod 410 can limit and guide the movable plate 404.

[0032] To ensure that those skilled in the art can fully understand the technical solution, this application provides the following overall overview:

[0033] In use, turning on the motor 207 drives the gear 208 to rotate and mesh with the tooth groove 205, which causes the vertical plate 203 to drive the lifting plate 202 to descend. The lifting plate 202 then drives the long rod 209 and the slump cylinder 5 to descend, so that the bottom surface of the slump cylinder 5 is in contact with the top surface of the base plate 1. This can fix the slump cylinder 5 during concrete filling and prevent it from moving. It eliminates the need for manual pressure to keep the slump cylinder 5 in place during concrete filling, making it more convenient. Pushing the push plate 408 moves the connecting rod 407, the moving plate 404, and the insert block 405, allowing the insert block 405 to move out of the connecting groove 406. The hopper 3 is then placed on the slump cylinder 5, and the connecting block 402 is inserted into the connecting groove 406. Releasing the push plate 408 allows the spring force of the spring 409 to push the moving plate 205 to move the slump cylinder 5. The plate 404 and the insert block 405 move, allowing the insert block 405 to be inserted into the slot 403, which can fix the connecting block 402, thereby fixing the hopper 3 onto the slump cylinder 5. This prevents the hopper 3 from moving when filling the slump cylinder with concrete, and it is more convenient as it does not require constant manual support. When the slump cylinder 5 needs to be lifted, the motor 207 is turned on to drive the gear 208 to rotate and mesh with the tooth groove 205, which causes the vertical plate 203 to drive the lifting plate 202 to descend. The lifting plate 202 drives the long rod 209 and the slump cylinder 5 to move upward away from the concrete pile. The height of the concrete pile is measured with a ruler, and the degree of collapse of the concrete pile is calculated based on the height of the slump cylinder 5. There is no need for manual lifting of the slump cylinder 5, making it very convenient to use.
