Therefore, the present invention is not limited to the specific embodiments disclosed below.

[0039] Secondly, the term "one embodiment" or "embodiment" as used herein refers to a specific feature, structure or characteristic that may be included in at least one implementation of the present invention. The term "in one embodiment" that appears in different places in this specification does not necessarily refer to the same embodiment, nor does it refer to a separate or selective embodiment that is mutually exclusive with other embodiments.

[0040] Example 1

[0041] Reference Figure 1-Figure 2 , which is the first embodiment of the utility model, and which provides a buffer silo with an emergency chute, comprising a silo portion 100, including a top plate 101 disposed inside the silo, and a fixing assembly 102 disposed below the top plate 101;

[0042] The adjusting component 200 includes a guide assembly 201 disposed in the silo portion 100, a sliding assembly 202 disposed on the silo portion 100, and a follower assembly 203 disposed on the sliding assembly 202; wherein the follower assembly 203 is connected to the guide assembly 201;

[0043] The silo part 100 is funnel-shaped as a whole, and its top and bottom are both open, so that materials can pass from top to bottom. A top plate 101 is fixedly provided in the silo part 100, and the top plate 101 is arranged in the middle of the silo part 100. The silo part 100 is provided with a fixing assembly 102 below the top plate 101. The top plate 101 is formed by connecting and splicing two inclined plates 203a at the highest point, so that after the materials enter the silo part 100, they are guided by the top plate 101 and fall on the fixing assembly 102, thereby completing the buffering of the materials.

[0044] The guide assembly 201 is arranged in the middle of the silo part 100, and the sliding assembly 202 can drive the guide assembly 201 to move through the follower assembly 203, so that the guide assembly 201 can further buffer the material, and then can adjust the buffering of the material as needed, and adjust the falling speed of the material.

[0045] Furthermore, the fixing assembly 102 includes a first guide plate 102a and a second guide plate 102b which are arranged on the inner side of the silo portion 100; wherein the first guide plate 102a is located above the second guide plate 102b, and two groups of first guide plates 102a are fixedly provided on the inner walls on both sides of the silo portion 100, the first guide plate 102a is located below the top plate 101, and two groups of second guide plates 102b are fixedly provided on the inner wall of the silo portion 100, the second guide plate 102b is located below the first guide plate 102a, and the tops of the first guide plate 102a and the second guide plate 102b are both inclined to prevent materials from staying on their surfaces, and the length of the second guide plate 102b is greater than the first guide plate 102a, so that after the material falls on the surface of the first guide plate 102a, it falls on the surface of the second guide plate 102b, and then performs secondary buffering.

[0046] Operation process: When the material enters the silo part 100, it first contacts the top plate 101, and the top plate 101 guides the material to fall on the surface of the first guide plate 102a. The material falls on the second guide plate 102b along the inclined surface of the first guide plate 102a. The second guide plate 102b buffers the material again, and finally the material falls along the surface of the second guide plate 102b and is discharged;

[0047] By configuring the top plate 101 and the fixing assembly 102 , when the material falls, it can be buffered at multiple levels, thereby reducing the impact of the material on the inner wall of the silo part 100 and reducing the wear of the inner wall of the silo part 100 .

[0048] Example 2

[0049] Reference Figure 1 to Figure 5 , which is the second embodiment of the utility model. Different from the previous embodiment, the guide assembly 201 includes a long plate 201a disposed in the silo part 100 and connecting shafts 201b disposed at both ends of the long plate 201a; wherein the long plate 201a is connected to the inner wall of the silo part 100 through the connecting shaft 201b;

[0050] The silo portion 100 is provided with two groups of long plates 201a between the two groups of first guide plates 102a, and the tops of the two groups of long plates 201a are fixedly connected with connecting shafts 201b, and the long plates 201a are rotatably connected to the inner wall of the silo portion 100 through the connecting shafts 201b. The two groups of long plates 201a are symmetrically arranged in the silo portion 100, and one group of connecting shafts 201b penetrates the side wall of the silo portion 100 and is connected to the follower component 203, so that the follower component 203 can drive the bottom end of the long plate 201a to rotate toward the inner wall of the silo portion 100, making it inclined, and then the material falling from the first guide plate 102a is buffered by the long plate 201a and falls on the second guide plate 102b, thereby increasing the buffering distance of the material and adjusting the falling speed of the material.

[0051] Furthermore, the sliding assembly 202 includes a connecting plate 202a arranged on the outside of the silo part 100, a rotating member 202b arranged on the connecting plate 202a, and a limiting portion 202c arranged between the rotating member 202b and the connecting plate 202a; wherein, the rotating member 202b is connected to the follower assembly 203; the connecting plate 202a is provided with two groups, both of which are fixedly provided on one side of the outside of the silo part 100, and the connecting plate 202a is located below the connecting shaft 201b, and a rotating member 202b is provided between the two groups of connecting plates 202a, and the rotating member 202b is connected to the follower assembly 203. During the rotation of the rotating assembly, the limiting portion 202c limits the rotating member 202b, so that the rotating member 202b drives the follower assembly 203 to move, and then drives the two groups of long plates 201a to rotate.

[0052] Furthermore, the rotating member 202b includes a bidirectional screw 202b-1 arranged on the connecting plate 202a, and a slider 202b-2 arranged on the bidirectional screw 202b-1; wherein the slider 202b-2 is connected to the follower assembly 203, and the bidirectional screw 202b-1 is rotatably connected between the two groups of connecting plates 202a, and a handle is fixed at the end of the bidirectional screw 202b-1, and the bidirectional screw 202b-1 is located on the outer side and is threadedly connected with two groups of sliders 202b-2, and the two groups of sliders 202b-2 are symmetrically arranged on the outer side of the bidirectional screw 202b-1, and a limiting portion 202c is provided between the two groups of sliders 202b-2 and the connecting plate 202a. When the bidirectional screw 202b-1 rotates, the limiting portion 202c limits and guides the slider 202b-2, so that the two groups of sliders 202b-2 slide in opposite directions, and drive the long plate 201a to rotate through the follower assembly 203.

[0053] Furthermore, the limiting portion 202c includes a cross bar 202c-1 arranged on the connecting plate 202a, and a socket plate 202c-2 arranged on the slider 202b-2; wherein the socket plate 202c-2 is socketed with the cross bar 202c-1; a cross bar 202c-1 is fixedly provided between the two groups of connecting plates 202a, and a socket plate 202c-2 is fixedly provided on the back of the two groups of sliders 202b-2, and the socket plate 202c-2 is socketed with the cross bar 202c-1. When the bidirectional screw 202b-1 rotates, the cross bar 202c-1 limits the slider 202b-2, so that the slider 202b-2 cannot rotate with the bidirectional screw 202b-1, and the thread of the bidirectional screw 202b-1 causes the slider 202b-2 to slide laterally, thereby driving the follower assembly 203 to rotate.

[0054] Furthermore, the follower assembly 203 includes an inclined plate 203a disposed at the end of the connecting shaft 201b, a waist-shaped groove 203b opened in the inclined plate 203a, and a fixed column 203c disposed on the slider 202b-2; wherein the inclined plate 203a is sleeved with the fixed column 203c through the waist-shaped groove 203b; the inclined plate 203a is fixedly disposed on the inclined plates 203a at the ends of two sets of connecting shafts 201b, the top end of the inclined plate 203a is connected to the connecting shaft 201b, and the inclined plate 203a is connected to the connecting shaft 201b. 3a has a waist-shaped groove 203b, and a fixed column 203c is fixed on the side of the slider 202b-2 away from the sleeve plate 202c-2. The inclined plate 203a is sleeved with the fixed column 203c through the waist-shaped groove 203b. When the slider 202b-2 slides in the direction away from each other, the slider 202b-2 hits the inclined plate 203a through the fixed column 203c. After being hit, the inclined plate 203a rotates around the connecting shaft 201b, so that the inclined plate 203a drives the long plate 201a to rotate.

[0055] The rest of the structure is the same as that of Example 1.

[0056] Operation process: When the long board 201a needs to be adjusted, the bidirectional screw 202b-1 is rotated by the handle. Due to the limit of the slider 202b-2 by the cross bar 202c-1, the two sets of sliders 202b-2 slide in the direction away from each other. During the sliding process of the slider 202b-2, the fixed column 203c is caused to resist the inclined plate 203a and rotate. The inclined plate 203a rotates around the connecting shaft 201b. After the inclined plate 203a rotates, it drives the long board 201a to rotate until the long board 201a rotates to be located below the first guide plate 102a and above the second guide plate 102b. The long board 201a is as shown in Figure 5 As shown, after the material passes through the first guide plate 102a, it falls on the surface of the long plate 201a. After being guided by the long plate 201a, the material falls on the second guide plate 102b and is discharged from the silo part 100 after passing through the second guide plate 102b, so that the material buffer distance can be adjusted as needed, the material falling speed can be adjusted, and the impact of the material on the inner wall of the silo part 100 can be further reduced.

[0057] Example 3

[0058] Reference Figure 1 to Figure 7 , which is the third embodiment of the utility model, is different from the previous embodiment in that it further includes a material guide component 300, which includes a blocking component 301 arranged on the silo part 100, and a chute component 302 arranged on one side of the silo part 100; wherein the chute component 302 corresponds to the silo part 100;

[0059] The end of the chute member 302 is connected to the silo part 100. The chute member 302 is a long inclined chute with a lower bottom. There are baffles on both sides of the inclined chute to prevent materials from falling from both sides. At the same time, the silo part 100 is provided with a through groove corresponding to the chute member 302. The through groove is located below the second guide plate 102b, so that the material can be discharged through the chute member 302 through the through groove. The blocking component 301 is arranged on one side of the silo part 100, which corresponds to the position of the through groove to prevent the material from being discharged from the through groove during daily use. When the transportation equipment below the silo part 100 is damaged, the bottom of the silo part 100 can be closed, and the blocking component 301 can be opened to discharge the material from the chute member 302, so that the equipment does not need to be stopped and can operate normally.

[0060] Further, the blocking assembly 301 includes two sets of guide plates 301a disposed on one side of the silo portion 100, and a drawer 301b disposed between the two sets of guide plates 301a, the drawer 301b includes a baffle 301b-1 disposed between the two sets of guide plates 301a, and a fixing strip 301b-2 disposed on the baffle 301b-1; two sets of guide plates 301a are fixedly disposed on one side of the outside of the silo portion 100, and the cross section of the guide plates 301a is "L" shaped, and Two groups of guide plates 301a are arranged on both sides of the through slot, and the baffle 301b-1 is inserted between the two groups of guide plates. A fixing bar 301b-2 is fixed on the baffle 301b-1. When the transport device at the bottom of the silo part 100 fails, the baffle 301b-1 can be pulled out through the fixing bar 301b-2, so that the material can fall from the through slot onto the chute part 302, and be discharged through the chute part 302, so that the blast furnace can operate normally, avoid the need for repeated start and stop of the equipment, and improve production efficiency.
