[0002] Silos are essential equipment between various unit operations in the material process and are storage equipment for various loose materials. However, in actual use, when materials are discharged from the silo, due to the friction and adhesion between particles and between particles and the inner wall of the silo, a dome is formed at the discharge port, blocking the discharge port and causing difficulty in discharging.

[0003] At present, the existing utility model with publication number CN201647472U discloses an arch breaking device, which includes an arch breaking rod and a linear motion driving device, one end of the linear motion driving device is hinged to the base, and the other end thereof is hinged to one end of the arch breaking rod, and the other end of the arch breaking rod is sleeved in the inner hole of the guide sleeve, and the two are clearance fit, the guide sleeve is installed on the silo, and a through hole is provided on the silo wall corresponding to the inner hole of the guide sleeve, and the arch breaking rod extends into and exits the silo through the through hole.

[0004] In the above scheme, a hydraulic cylinder is used for poking the material. This scheme can partially solve the above-mentioned arching problem. However, for occasions with a larger arching area, since the end area of ​​the poking device is limited, the arch breaking area is also limited. Therefore, in this case, the problem of material arching cannot be completely eliminated. Utility Model Content

[0016] The utility model is further configured as follows: the second connection assembly includes a right-angle joint installed at the ends of multiple first connection pipes located above, and the same third connection pipe is installed at the connection port of the right-angle joint and the second three-way joint.
