It is understood that the specific embodiments described herein are only used to explain the relevant utility model, rather than to limit the utility model. It is also necessary to explain that, for the convenience of description, only the parts related to the utility model are shown in the accompanying drawings.
[0033] It should be noted that, in the absence of conflict, the embodiments and features of the embodiments of the present invention can be combined with each other. The present invention will be described in detail below with reference to the accompanying drawings and in combination with the embodiments.

[0035] The silo 1 is connected to a feed hopper 11 at the top, and a vibration motor 12 and a pneumatic fluidization device 13 are arranged on one side near the bottom;
[0036] A lifting discharging mechanism 2, the bottom end of which extends from the top of the silo 1 to the bottom of the silo;
[0037] The pressure reducing mechanism 3 is arranged in the silo 1 and is used to reduce the material pressure at the bottom of the silo 1;
[0038] The anti-caking mechanism 4 is arranged at the bottom end of the lifting and discharging mechanism 2.
[0039] In this embodiment, the material enters the silo 1 through the feed hopper 11 and accumulates, and the pressure reducing mechanism 3 can reduce the material pressure at the bottom of the silo 1. When discharging, the material is lifted from the bottom of the silo 1 to the outside of the silo 1 by the lifting discharging mechanism 2, and the material at the feeding port of the lifting discharging mechanism 2 is stirred by the anti-caking mechanism 4.
[0040] The composite lifting silo of the present application has a simple structure and a small installation volume. The material is lifted to the outside of the silo 1 by lifting the discharge mechanism 2, which effectively alleviates the problem of easy blockage and easy compaction of the material.
[0041] In a preferred embodiment, if Figure 1 As shown, the silo 1 includes a silo body 14 and an inverted cone section 15 arranged at the bottom end of the silo body; the top of one side of the silo body 14 is connected to an exhaust pipe 16; the outer periphery of the inverted cone section 15 is evenly distributed with supporting legs 17; the vibration motor 12 and the pneumatic fluidization device 13 are installed on the side wall of the inverted cone section 15.
[0042] In this embodiment, the vibration motor 12 works intermittently. When the material is not discharged smoothly, it vibrates for 5s to 30s to ensure that the material enters the spiral inlet smoothly. The pneumatic fluidization device 13 works intermittently to help the flow of the material in the inverted cone section 15. The interval time is set according to different materials, which effectively ensures smooth feeding. The exhaust equipment is used to suck away the smoke and dust in the silo 1 through the exhaust pipe 16, so that a slight negative pressure is generated in the silo 1 to prevent dust from overflowing and polluting the environment.

A reduction motor 26 for driving the hanging shaft 22 to rotate is fixedly provided on the top of the material pipe 21 to adjust the rotation speed of the hanging shaft 22. Bolt blades 27 are fixedly provided on the outer wall of the hanging shaft 22 from the bottom to the top, so that the material can be easily transported.
[0046] In a preferred embodiment, a group of split bearings 24 are installed on the suspension shaft 22 at intervals of 2.5-4 m to provide stable support.
[0047] In a preferred embodiment, the pitch of the bolt blade 27 at the bottom of the material pipe 21 is 1-2 times the pitch of the bolt blade 27 inside the material pipe 21. The larger the pitch, the easier it is for the material to enter the material pipe 21 and the less likely it is to get clogged.
[0048] In a preferred embodiment, the distance between the bottom end of the material pipe 21 and the bottom of the silo 1 is 40-60 cm.
[0049] In a preferred embodiment, if Figure 1 As shown, the pressure relief mechanism 3 includes a side wall pressure relief plate 31 fixedly arranged on the inner wall of the silo 1 along the circumferential direction and a central pressure relief plate 32 fixedly arranged on the outer wall of the lifting and discharging mechanism 2 along the circumferential direction;

The side wall pressure relief plates 31 and the central pressure relief plates 32 are alternately distributed.
[0051] In this embodiment, the side wall pressure relief plates 31 and the central pressure relief plates 32 are staggered to avoid blocking the material from being discharged, while at the same time stratifying the material to share the material pressure and reduce the compaction of the material.
[0052] In a preferred embodiment, if Figure 1 As shown, the side wall pressure relief plate 31 is tilted downward by 30°-50° in a direction away from the inner wall of the silo 1 ; the central pressure relief plate 32 is tilted downward by 30°-50° in a direction away from the lifting and discharging mechanism 2 .
[0053] In a preferred embodiment, the width of the side wall pressure relief plate 31 is 1 / 6-1 / 4 of the radius of the inner wall of the silo 1 ; the width of the central pressure relief plate 32 is 1 / 6-1 / 4 of the radius of the inner wall of the silo 1 .
[0054] In a preferred embodiment, the anti-caking mechanism 4 includes a plurality of stirring blades or a plurality of stirring rods arranged between the bottom end of the material pipe 21 and the bottom of the silo 1, the stirring blades or stirring rods are uniformly distributed on the outer periphery of the hanging shaft 22 along the circumferential direction, and are fixedly connected to the hanging shaft 22, and the anti-caking mechanism 4 adopts a driving structure integrated with the hanging shaft 22. The anti-caking mechanism 4 has a simple structure and is easy to obtain materials. It stirs the materials near the spiral inlet to increase the fluidity of the materials at the bottom of the inverted cone section 15 and the spiral inlet, and can also prevent the materials from being compacted due to various reasons, so that the material feeding is more stable and uniform.
