[0029] The vibration assembly 3 includes a fixed ring 301 fixedly mounted on the outer wall of the silo 1, the fixed ring 301 is located between the upper ventilation ring 201 and the lower ventilation ring 202, an annular groove 302 is provided on the fixed ring 301, an extrusion block 303 is installed at an equal angle on the outer wall of the silo 1, the extrusion block 303 is located above the fixed ring 301, an annular disc 304 is rotatably installed inside the annular groove 302, a tooth groove 305 is opened at an equal angle on the outer wall of the annular disc 304, a gear 306 is provided on one side of the annular disc 304, the gear 306 is meshed with the tooth groove 305, the gear 306 is fixedly connected to the output shaft of the motor 307, the motor 307 is fixedly mounted on the mounting frame, the mounting frame is fixedly mounted on the outer wall of the silo 1, a mounting platform 308 is fixedly mounted on the top of the annular disc 304, a transverse cylinder 309 is fixedly mounted on the top of the mounting platform 308, and the transverse cylinder 30 9 is movably installed with a movable plate 310 inside, and a cross bar 311 is fixedly installed on the side of the movable plate 310 close to the silo 1, one end of the cross bar 311 penetrates to the side of the transverse tube 309 close to the silo 1, and a vibration block 312 is fixedly installed on one end of the cross bar 311, and a spring 313 is fixedly installed on the side of the movable plate 310 away from the vibration block 312, the outer wall of the vibration block 312 contacts the outer wall of the silo 1, and the vibration block 312 and the extrusion block 303 are on the same horizontal plane, and the annular disk 304 rotates. When the vibration block 312 contacts the extrusion block 303, the vibration block 312 moves toward the transverse tube 309 under the action of pressure, and when the vibration block 312 separates from the extrusion block 303, the vibration block 312 knocks on the outer wall of the silo 1 under the elastic force of the spring 313, vibrates the silo 1, facilitates material unloading, and further improves the effect of eliminating the arch phenomenon.

[0031] Working principle: When working, first, the silo 1 is installed on the top of the rotor scale, and the raw materials are stored on the top of the silo 1. When the raw materials are discharged, the raw materials pass through the rotor scale, and the rotor scale weighs the incoming raw materials;

[0032] When there is an arching phenomenon inside the silo 1, it is first determined whether the arching phenomenon occurs in the upper layer or the lower layer inside the silo 1. If it occurs in the upper layer, the first solenoid valve 205 is opened by the controller. If it occurs in the lower layer, the second solenoid valve 206 is opened by control. At this time, the air pump drives the outside air to be sprayed from the nozzle 207 toward the inside of the silo 1 through the connecting pipe 204 and the connecting pipe 203 to disperse the arched raw materials.

[0033] Since the first solenoid valve 205 and the second solenoid valve 206 are arranged in parallel, the motor 307 and the parallel circuit formed by the first solenoid valve 205 and the second solenoid valve 206 are arranged in series, when one of the first solenoid valve 205 and the second solenoid valve 206 is opened, the motor 307 can be powered on;

[0034] When the motor 307 is powered on, the gear 306 rotates. Since the gear 306 is meshed with the tooth groove 305, the annular disk 304 is driven to rotate. When the vibration block 312 contacts the extrusion block 303, the vibration block 312 moves toward the transverse cylinder 309 under the action of pressure. When the vibration block 312 is separated from the extrusion block 303, the vibration block 312 strikes the outer wall of the silo 1 under the elastic force of the spring 313, vibrating the silo 1 to facilitate material unloading and further improve the effect of eliminating the arching phenomenon.
