It should be understood that the specific embodiments described herein are only used to explain this utility model and are not intended to limit this utility model.

[0023] This utility model provides a device for breaking arches in the large funnel of a ship unloader, the structure of which is as follows: Figure 1 and Figure 2 As shown, it includes multiple anti-bridging belts 100 and a driving mechanism 200. Each anti-bridging belt 100 is disposed in the cavity of the large funnel 1, and one end of each anti-bridging belt 100 is connected to the large funnel 1. The driving mechanism 200 is connected to the other end of each anti-bridging belt 100 and is used to drive the other end of each anti-bridging belt 100 to move so that each anti-bridging belt 100 disturbs the material.

[0024] In use, one end of each of the arch-breaking belts 100 is connected to the large funnel 1, and the driving mechanism 200 is connected to the other end of each of the arch-breaking belts 100. Material is put into the large funnel 1. By operating the driving mechanism 200, the driving mechanism 200 can drive the other end of each of the arch-breaking belts 100 to move, thereby causing each of the arch-breaking belts 100 to disturb the material, break up the agglomerates and bridging formed in the large funnel 1, ensure the smoothness of material discharge, speed up the discharge speed, and improve the unloading efficiency.

[0025] As a preferred embodiment, please refer to Figure 1 and Figure 2 The upper end of each of the arch-breaking belts 100 is connected to the large funnel 1, and the driving mechanism 200 is connected to the lower end of each of the arch-breaking belts 100. It is used to drive the lower end of each of the arch-breaking belts 100 to reciprocate in the horizontal plane. On the one hand, this allows each of the arch-breaking belts 100 to disturb the material laterally, improving the arch-breaking effect on the material. On the other hand, the vertical arrangement of each of the arch-breaking belts 100 also facilitates the arrangement of the driving mechanism 200.

[0026] As a preferred embodiment, please refer to Figure 2 The arch-breaking belt 100 is at least partially elastic. When the driving mechanism 200 drives the lower end of each of the arch-breaking belts 100 to reciprocate in the horizontal plane, each of the arch-breaking belts 100 will be continuously stretched and reset. During the deformation of the arch-breaking belt 100, it will also cause longitudinal disturbance to the nearby material, further improving the arch-breaking effect on the material.

[0027] As a preferred embodiment, please refer to Figure 2The arch-breaking belt 100 includes an elastic section 110 and a disturbance section 120 connected to each other. The upper end of the elastic section 110 is connected to the large funnel 1, and the driving mechanism 200 is connected to the lower end of the disturbance section 120. The disturbance section 120 disturbs the material laterally, and the elastic section 110 disturbs the material longitudinally, resulting in a significant arch-breaking effect.

[0028] As a preferred embodiment, please refer to Figure 2 The elastic segment 110 is a spring. When the driving mechanism 200 drives the lower ends of each of the arch-breaking belts 100 to reciprocate in the horizontal plane, each of the springs will be continuously stretched and continuously reset. During the deformation of the spring, a force will be applied to the disturbance segment 120, thereby causing longitudinal disturbance to the nearby materials.

[0029] As a preferred embodiment, please refer to Figure 2 The disturbance section 120 is a chain, which can laterally disturb the material.

[0030] As a preferred embodiment, please refer to Figure 2 The length of the elastic segment 110 in its initial state is less than the length of the disturbance segment 120, and the breaking of the arch of the material mainly depends on the lateral disturbance of the disturbance segment 120.

The lower end of each of the arch-breaking belts 100 is connected to one end of the connecting frame 210. The turntable 220 is eccentrically connected to the other end of the connecting frame 210. The output end of the rotation driving component 230 is coaxially fixedly connected to the turntable 220 and is used to drive the turntable 220 to rotate. When the rotation driving component 230 is activated, the output end of the rotation driving component 230 rotates, driving the turntable 220 to rotate.

The lower ends of each of the arch-breaking belts 100 are respectively connected to the horizontal bar 211 and the vertical bar 212. The connecting rod 213 is disposed outside the large funnel 1. One end of the connecting rod 213 is hinged to one end of the horizontal bar 211. The turntable 220 is eccentrically hinged to the other end of the connecting rod 213. The rotation drive component... When 230 is started, the output end of the rotation drive 230 rotates, driving the turntable 220 to rotate. During the rotation of the turntable 220, the horizontal bar 211 will reciprocate through the transmission action of the connecting rod 213, and the vertical bar 212 will reciprocate, so that the lower ends of each of the arch-breaking belts 100 reciprocate in the horizontal plane. Each of the arch-breaking belts 100 can laterally disturb the material. The rotation drive 230 can be directly and coaxially fixedly connected to the turntable 220 by a suitable type of motor, or it can be connected to the turntable 220 by a transmission mechanism such as a gear set or pulley set.

During the rotation of the turntable 220, the horizontal bar 211 reciprocates in the horizontal plane via the transmission action of the connecting rod 213, and the vertical bar 212 reciprocates in the horizontal plane. When the horizontal bar 211 and the vertical bar 212 reciprocate in the horizontal plane, the two anti-arching bands 100 arranged on both sides of the horizontal bar 211 will swing back and forth, and the two anti-arching bands 100 arranged on both sides of the vertical bar 212 will alternately approach or...

As the lower ends of each of the arch-breaking belts 100 reciprocate in the horizontal plane, the elastic segments 110 of each of the arch-breaking belts 100 are continuously stretched and reset. During the deformation of the elastic segments 110, longitudinal disturbance is also generated on the nearby material, further improving the arch-breaking effect. Each disturbance segment 120 causes lateral disturbance to the material, and each elastic segment 110 causes longitudinal disturbance to the material, resulting in a significant arch-breaking effect.

[0039] (1) When the lower end of each of the arch-breaking belts 100 reciprocates in the horizontal plane, the elastic segment 110 of each of the arch-breaking belts 100 will be continuously stretched and continuously reset. During the deformation of the elastic segment 110, it will also cause longitudinal disturbance to the nearby material, further improving the arch-breaking effect on the material. Each of the disturbance segments 120 causes lateral disturbance to the material, and each of the elastic segments 110 causes longitudinal disturbance to the material, resulting in a significant arch-breaking effect.

[0040] (2) When the crossbar 211 and the longitudinal bar 212 move back and forth in the horizontal plane, the two arch-breaking bands 100 arranged on both sides of the crossbar 211 will swing back and forth, and the two arch-breaking bands 100 arranged on both sides of the longitudinal bar 212 will alternately move closer to or away from the center of the large funnel 1, thereby achieving all-round disturbance of the material.
