[0014] Beneficial effects of the utility model:

[0015] 1.

Then, the piston rod of the cylinder pushes the push block to move, driving the sealing block to slide along the fixed block and the overflow pipe, and the sealing block is separated from the arc groove. When the cement exceeds the overflow height and enters the overflow pipe, the arc block is pushed to rotate along the rotating shaft, and the spring is compressed.

[0016] 2. The initial state of the spring makes the outer wall of the arc block suitable for contacting the inner wall of the overflow pipe, blocking the dust inside the cement silo body, reducing the occurrence of dust entering the recovery pipe through the overflow pipe, and reducing the loss of cement when stored inside the cement silo body; when cement enters the recovery pipe from the overflow pipe, it pushes the arc block to rotate counterclockwise. When the position of cement inside the cement silo body drops, the cement remaining in the overflow pipe pushes the arc block to rotate clockwise. At this time, the spring is stretched, so that the cement remaining in the overflow pipe returns to the inside of the cement silo body, reducing the residue and waste of cement, and facilitating the storage and use of cement by the cement silo body.

[0017] 3. When storing cement through the cement silo body, when a large amount of cement suddenly enters the cement silo body, when the cement exceeds the set storage height and cannot be discharged to the outside from the overflow pipe in time, too much cement enters the overflow silo from the overflow trough, reducing the damage of the cement silo body caused by too much cement and improving the anti-overflow effect of the cement silo body.

[0018] 4. When the position of cement inside the cement silo body is lower than the reflux groove, the cement inside the overflow bin pushes the arc-shaped block to slide along the reflux groove into the cement silo body, and the arc-shaped block drives the connecting rod to slide along the overflow bin. The tension spring is stretched, and the overflowed cement is returned to the cement silo body. After the reflux is completed, the arc-shaped block is re-engaged with the reflux groove through the restoring force of the tension spring, completing the sealing of the cement silo body, which is convenient for anti-overflow use again. The overflow bin and the overflow pipe provide two anti-overflow methods, which effectively reduce the risk of overflow of the cement silo body during use, protect the integrity of the cement silo body, and reduce the waste of cement resources during storage.

[0032] The valve component 7 includes a fixed block 701, which is installed on the outer wall of the overflow pipe 5. A sealing block 702 is inserted into the fixed block 701, and the sealing block 702 is plugged into the overflow pipe 5. An arc groove 703 is opened on the inner wall of the overflow pipe 5, and the sealing block 702 is plugged into the arc groove 703. A cylinder 704 is installed on the top surface of the fixed block 701 through a mounting seat, and a push block 705 is fixedly connected to the top surface of the sealing block 702. The piston rod of the cylinder 704 is connected and fixed to the outer wall of the push block 705; the push block 705 is pushed to move by the piston rod of the cylinder 704, driving the sealing block 702 to slide along the fixed block 701 and the overflow pipe 5, and the sealing block 702 is separated from the arc groove 703. When the cement exceeds the overflow height and enters the overflow pipe 5,

[0033] During use, when cement is stored through the cement silo body 1, when cement needs to be stored to different heights, the valve component 7 on the overflow pipe 5 of the corresponding height is opened, the remaining valve components 7 are closed, and then the piston rod of the cylinder 704 pushes the push block 705 to move, driving the sealing block 702 to slide along the fixed block 701 and the overflow pipe 5, and the sealing block 702 is separated from the arc groove 703.

[0039] An arc-shaped stopper 1001 is slidably connected inside the reflux groove 10, and the lower end of the overflow bin 8 is symmetrically structured and slidably connected to two connecting rods 801. A tension spring 802 is fixed to the rear end of the connecting rod 801, and the other end of the tension spring 802 is connected and fixed to the overflow bin 8. The front ends of the two connecting rods 801 are connected and fixed to both ends of the arc-shaped stopper 1001, and the connecting rods 801 are slidably connected to the cement bin body 1; the cement inside the overflow bin 8 pushes the arc-shaped stopper 1001 to slide along the reflux groove 10 toward the inside of the cement bin body 1, and the arc-shaped stopper 1001 drives the connecting rod 801 to slide along the overflow bin 8, so that the overflowed cement flows back to the inside of the cement bin body 1.

[0040] When in use, when cement is stored through the cement silo body 1, when a large amount of cement suddenly enters the cement silo body 1, when the cement exceeding the set storage height cannot be discharged to the outside from the overflow pipe 5 in time, the excess cement enters the overflow bin 8 from the overflow groove 9, thereby reducing the damage of the cement silo body 1 caused by the excess cement, and improving the anti-overflow effect of the cement silo body 1;

[0041] When the position of cement inside the cement silo body 1 is lower than the reflux groove 10, the cement inside the overflow bin 8 pushes the arc block 1001 to slide along the reflux groove 10 toward the inside of the cement silo body 1, and the arc block 1001 drives the connecting rod 801 to slide along the overflow bin 8. The tension spring 802 is stretched, and the overflowed cement is returned to the inside of the cement silo body 1. After the reflux is completed, the arc block 1001 is re-engaged with the reflux groove 10 through the restoring force of the tension spring 802, completing the sealing of the cement silo body 1, which is convenient for anti-overflow use again. The overflow bin 8 and the overflow pipe 5 provide two anti-overflow methods, which effectively reduce the risk of overflow of the cement silo body 1 during use, protect the integrity of the cement silo body 1, and reduce the waste of cement resources during storage.
