[0035] See also Figure 1 and Figure 2 The embodiment of the present application provides a mine bin 10, comprising a bin body 100 and a plurality of inspection doors 200. The bin body 100 has a chamber 110 and a plurality of inspection openings connected to the chamber 110, the plurality of inspection openings are arranged on the side of the bin body 100, and the plurality of inspection openings are arranged at intervals along the height direction of the bin body 100; the plurality of inspection doors 200 are arranged one by one corresponding to the plurality of inspection openings, and the inspection doors 200 can be installed in the corresponding inspection openings in an openable and closable manner.

[0036] The silo body 100 is the basic component of the ore silo 10, and is used to provide installation and protection for other components of the ore silo 10. The chamber 110 of the silo body 100 is used to store ore materials. The silo body 100 also has a feed port 120 and a discharge port 130 connected to the chamber 110. The feed port 120 is arranged at the top of the silo body 100, and the discharge port 130 is arranged at the bottom of the silo body 100. Ore materials such as pellets enter the chamber 110 through the feed port 120 and fall from the discharge port 130 to the belt below.

[0037] Multiple inspection openings are arranged at intervals along the height direction of the warehouse body 100, that is, multiple inspection openings are arranged along the vertical direction, and each inspection opening is correspondingly provided with an inspection door 200, and the inspection door 200 can be installed in the corresponding inspection opening in an openable and closable manner, that is, the inspection door 200 can open or close the inspection opening.

[0038] In a mining bin 10 provided in the present application, since a plurality of inspection openings are arranged at intervals along the height direction of the bin body 100, the inspection doors 200 can be installed at the corresponding inspection openings in an openable and closable manner. Therefore, when the bin body 100 is worn, the inspection door 200 at the corresponding height can be opened, and the operator observes the material surface 20 in the bin body 100 through the inspection opening, and coordinates with the production to pull the material so that the material surface 20 drops to a position below the inspection opening. At this time, the operator enters the bin body 100 through the inspection opening, and uses the material surface 20 as the inspection plane, that is, the operator stands on the material surface 20 to repair the bin body 100, so that the operator does not need to enter the bin body 100 from the top of the bin body 100, thereby reducing the drop and improving the safety of the operation.

[0039] For example, two inspection ports may be provided, which are respectively provided at 1 / 3 and 2 / 3 of the height of the silo 100. Figure 3 , when it is necessary to repair the space above 2 / 3 in the height direction of the silo body 100, open the inspection door 200 at the top to observe the material feeding situation, and when coordinating with the production to pull the material until the material surface 20 drops to 200mm below the inspection port, stop pulling the material, and at this time, the operator enters the silo body 100 through the inspection port, and uses the silo material surface 20 to treat the damaged space above the 2 / 3 position; when repairing the space between 2 / 3 and 1 / 3 in the height direction of the silo body 100, similarly, open the inspection door 200 at the bottom, and gradually lower the material surface 20 until it reaches the 1 / 3 position, and at this time, the operator enters the silo body 100 through the inspection port, and uses the silo material surface 20 to treat the damaged space between 2 / 3 and 1 / 3; please refer to Figure 4 When the space from 1 / 3 of the height of the silo 100 to the bottom is repaired, similarly, the inspection door 200 below is opened, and the material surface 20 is lowered step by step until it finally reaches the bottom position. At this time, the operator enters the silo 100 through the inspection port and uses the silo material surface 20 to process the damaged space from 1 / 3 to the bottom.

[0040] See also Figure 5 and Figure 6 In some embodiments, the inspection door 200 includes a door body 210, a connector 220 and a protective assembly 230. The door body 210 is connected to the outside of the warehouse body 100, the connector 220 passes through the door body 210 and the warehouse body 100, and the protective assembly 230 is connected to the inner wall of the chamber 110 and covers the portion of the connector 220 located in the chamber 110.

[0041] The door body 210 is connected to the outside of the warehouse body 100, so that the inspection port can be opened or closed. The connector 220 is provided through the door body 210 and the warehouse body 100, that is, the door body 210 and the warehouse body 100 are connected, when part of the connector 220 is located inside the warehouse body 100 and part of it is located outside the warehouse body 100. The protection component 230 is connected to the inner wall of the chamber 110 and covers the part of the connector 220 located inside the chamber 110, so that the mineral material can be prevented from falling and impacting the connector 220 to a certain extent, causing damage to the connector 220, so that the installation of the inspection door 200 is more stable.

[0042] Specifically, the connecting member 220 includes a stud bolt 221 and two nuts 222. The stud bolt 221 is inserted through the door body 210 and the warehouse body 100. The two nuts 222 are respectively arranged at both ends of the stud bolt 221 and pressed against the warehouse body 100, so that the door body 210 and the warehouse body 100 are connected. In addition, it can be understood that a hole needs to be opened on the warehouse body 100 for the stud bolt 221 to pass through. In order to prevent the stud bolt 221 from falling off from the hole, a limiting plate 240 can also be provided. The limiting plate 240 is sleeved on the stud bolt 221 and is located in the warehouse body 100, and is pressed on the warehouse body 100 by the nuts 222 on the same side, so that the stud bolt 221 can be prevented from falling off from the hole under the limiting position of the limiting plate 240. Of course, the protection component 230 can be connected to the limiting plate 240 located in the warehouse body 100.

[0043] Of course, a plurality of connectors 220 may be provided to ensure the installation stability of the door body 210 on the warehouse body 100 , and a protective assembly 230 is provided corresponding to each connector 220 .

[0044] See also Figure 7 In some embodiments, the protection assembly 230 includes a protection sleeve 231 and a multi-layer receiving platform 232 disposed on the top of the protection sleeve 231. The multi-layer receiving platform 232 is spaced apart along the height direction of the warehouse body 100, and the protection sleeve 231 is sleeved on the portion of the connecting piece 220 located in the chamber 110.

[0045] Since the protective sleeve 231 is sleeved on the portion of the connector 220 located in the chamber 110, the connector 220 can be protected. Since a multi-layer receiving platform 232 is provided on the top of the protective sleeve 231, the falling ore will accumulate on the receiving platform 232 without impacting the protective sleeve 231, further strengthening the protection of the connector 220. In addition, the ore is accumulated on the receiving platform 232, and the subsequent falling ore will impact the ore on the receiving platform 232, forming a "material hitting material" form, reducing the direct impact of the ore on the receiving platform 232.

[0046] Furthermore, since the multiple layers of receiving platforms 232 are arranged at intervals along the height direction of the warehouse body 100, it is understandable that the mineral materials will first impact the receiving platform 232 on the top layer. Even if the receiving platform 232 on the top layer is damaged, the receiving platforms 232 on the bottom layer can continue to receive materials, thus forming a multi-level protection. When all the receiving platforms 232 are damaged by the mineral materials, the production is basically over, so that the connecting piece 220 can be guaranteed not to be impacted during the entire production cycle, so that the inspection door 200 can be stably installed.

[0047] In some embodiments, the warehouse body 100 also has a feed port 120 connected to the chamber 110, and the feed port 120 is arranged at the top of the warehouse body 100. The receiving platform 232 includes two platforms 2321 arranged opposite to each other. The two platforms 2321 are both inclined, and the angle formed by the two platforms 2321 is toward the feed port 120.

[0048] Since the material receiving platform 232 includes two platforms 2321 arranged opposite to each other, the two platforms 2321 are both inclined, and the angle formed by the two platforms 2321 is toward the feed port 120, the accumulation of mineral materials on the material receiving platform 232 can be strengthened, the effect of "material hitting material" can be improved, and the impact of mineral materials on the material receiving platform 232 can be reduced, thereby strengthening the protection effect of the connecting piece 220.

[0049] See also Figure 5 and Figure 6 In some embodiments, the door body 210 includes a door panel 211 and a material stacking piece 212 . The material stacking piece 212 is connected to the outside of the warehouse body 100 . The material stacking piece 212 has a material stacking cavity 213 connected to the corresponding inspection port. The door body 210 is connected to the material stacking piece 212 .

[0050] The connecting piece 220 is passed through the material stacking piece 212 and the bin body 100 so that the material stacking piece 212 is connected to the outer side of the bin body 100. The door panel 211 can be movably connected to the material stacking piece 212 through a rotating shaft to open or close the inspection port. Since the material stacking piece 212 has a material stacking cavity 213 connected to the corresponding inspection port, during the falling process, a part of the ore will also be accumulated in the material stacking cavity 213 through the inspection port, forming the form of "material hitting material", thereby reducing the direct impact of the ore on the door panel 211, reducing the impact on the door panel 211, protecting the door panel 211, and extending the service life of the door panel 211.

[0051] Of course, part of the stacking piece 212 may also be directly embedded in the inspection opening to further improve the installation stability of the door body 210, and there is no limitation to this.

[0052] See also Figure 2 and Figure 8 In some embodiments, the bin body 100 further includes a feed port 120 connected to the chamber 110, and the feed port 120 is disposed at the top of the bin body 100. The ore bin 10 further includes a repair structure 300, and the repair structure 300 includes a connecting plate 310 and a receiving plate 320 disposed at an angle, and the connecting plate 310 is connected to the inner wall of the chamber 110.

[0053] Since the connecting plate 310 and the receiving plate 320 are arranged at an angle, and the connecting plate 310 is connected to the inner wall of the chamber 110, the receiving plate 320 can receive the material, that is, when the mineral material falls, it will accumulate on the receiving plate 320, and the subsequent mineral material will impact the mineral material accumulated on the receiving plate 320, also forming a "material hitting material" form, thereby reducing the impact of the mineral material on the connecting plate 310, and further reducing the impact of the mineral material on the inner wall of the chamber 110. Of course, since the inner wall of the chamber 110 is curved, the connecting plate 310 is also curved to fit the inner wall of the chamber 110, and the receiving plate 320 can also be a curved plate, and the opening of the receiving plate 320 faces the feed port 120 to facilitate the accumulation of the mineral material on the receiving plate 320.

[0054] When repairing the worn position of the silo body 100, the repair structure 300 can be installed at the worn position, and the connecting plate 310 can cover the worn position to achieve repair of the worn position. The receiving plate 320 is used to stack the mineral material to reduce the impact of the mineral material on the connecting plate 310, thereby protecting the silo body 100.

[0055] Of course, the repair structure 300 may be installed at a non-wear position of the bin body 100 to simply provide preventive protection for the bin body 100, and there is no limitation to this.

[0056] See also Figure 8 and Fig. 9In some embodiments, the repair structure 300 further includes a connector 220 and a protective component 230 , wherein the connector 220 passes through the connecting plate 310 and the chamber body 100 , and the protective component 230 is connected to the inner wall of the chamber 110 and covers the portion of the connector 220 located in the chamber 110 .

[0057] The connecting member 220 is provided through the connecting plate 310 and the warehouse body 100, that is, the connecting plate 310 and the warehouse body 100 are connected. The connecting member 220 and the protective assembly 230 here are completely consistent with the connecting member 220 and the protective assembly 230 mentioned above, that is, the connecting member 220 includes a stud bolt 221 and two nuts 222. The stud bolt 221 is provided through the door body 210 and the warehouse body 100. The two nuts 222 are provided at both ends of the stud bolt 221 and are pressed against the warehouse body 100, so that the connecting plate 310 and the warehouse body 100 are connected. The protective assembly 230 includes a protective sleeve 231 and a multi-layer receiving platform 232 provided on the top of the protective sleeve 231. The multi-layer receiving platform 232 is provided at intervals along the height direction of the warehouse body 100. The protective sleeve 231 is sleeved on the part of the connecting member 220 located in the chamber 110. The receiving platform 232 includes two platforms 2321 arranged opposite to each other. The two platforms 2321 are both inclined, and the angle formed by the two platforms 2321 is toward the feed port 120, which will not be described in detail here.

[0058] Since the protection assembly 230 protects the connection member 220, the connection plate 310 can be installed more stably on the inner wall of the chamber 110, thereby improving the repair effect of the repair structure 300. Of course, multiple connection members 220 can be provided to improve the installation stability of the connection plate 310 on the warehouse body 100.

[0059] It should be noted that in the related art, when repairing the worn parts of the silo 100, wear-resistant plates are embedded in the worn parts, which apparently play a wear-resistant role, but as the material pulling cycle proceeds, the wear-resistant plates embedded in the silo 100 will continue to fall from the silo 100, resulting in blockage of the on-site material warehouse. In the present application, due to the provision of the material receiving plate 320, a "material hitting material" form is formed, which reduces the impact of the mineral material on the connecting plate 310, and can improve the situation of the connecting plate 310 falling. In addition, the connector 220 connecting the silo 100 and the connecting plate 310 is also protected by the protective assembly 230, which further makes the installation of the connecting plate 310 stable and reduces the situation of the repair structure 300 falling.

[0060] See also Figure 2 and Fig.10 In some embodiments, the silo body 100 further has a discharge port 130 connected to the chamber 110 , and the discharge port 130 is disposed at the bottom of the silo body 100 . The ore silo 10 further includes a material receiving assembly 400 , and the material receiving assembly 400 is disposed at the bottom of the chamber 110 and covers the discharge port 130 .

[0061] In the related art, the production is generally “direct filling and direct unloading”, that is, the ore material falls from the feed port 120 and then comes out from the discharge port 130 . However, the drop of the ore material is too large, which will cause the ore material to strongly impact the discharge port 130 and damage the structure around the discharge port 130 .

[0062] In the embodiment of the present application, since a material receiving assembly 400 is provided, the material receiving assembly 400 is provided at the bottom of the chamber 110 and covers the material outlet 130, so that the material outlet 130 can be protected to prevent the mineral material falling from the material inlet 120 from directly impacting the material outlet 130. The material receiving assembly 400 can be used for receiving materials, that is, the mineral material will be accumulated on the material receiving assembly 400 until the mineral material can no longer be accumulated on the material receiving assembly 400, and the subsequent falling mineral material will first impact the mineral material accumulated on the material receiving assembly 400, and then fall to the material outlet 130 for discharge, so that the drop of the mineral material can be greatly reduced, the impact on the material outlet 130 can be reduced, and the production state of direct filling and direct unloading can be ensured at the same time.

[0063] In some embodiments, the material receiving assembly 400 includes a bracket 410 and a material receiving structure 420 . The bracket 410 covers the material outlet 130 , and the bracket 410 supports the material receiving structure 420 .

[0064] The material receiving structure 420 is used for receiving materials, the bracket 410 covers the discharge port 130, and the bracket 410 supports the material receiving structure 420, that is, the material receiving structure 420 is placed on the bracket 410, so that the mineral material will first accumulate on the material receiving structure 420 to avoid the mineral material falling from the feed port 120 directly impacting the discharge port 130. Of course, the bracket 410 is a non-closed structure, so the mineral material falling from the material pile on the material receiving structure 420 can enter the discharge port 130 for discharge.

[0065] In some embodiments, the material receiving structure 420 includes a material receiving hopper 421 and a plurality of ring plates 422, wherein the plurality of ring plates 422 are disposed in the material receiving hopper 421 and are spaced apart radially along the material receiving hopper 421, wherein the height of the material receiving hopper 421 is higher than the ring plates 422, and the heights of the plurality of ring plates 422 decrease successively from the outside to the inside in the radial direction of the material receiving hopper 421.

[0066] The mineral material will accumulate on the receiving hopper 421. Since the height of the receiving hopper 421 is higher than the ring plate 422, it is obvious that the falling mineral material will first impact the edge of the opening of the receiving hopper 421. When the edge of the opening of the receiving hopper 421 is damaged by the impact, since multiple ring plates 422 are arranged at radial intervals along the receiving hopper 421 and the heights of multiple ring plates 422 decrease successively from the outside to the inside in the radial direction of the receiving hopper 421, the falling mineral material will impact the next layer of ring plates 422, and so on, until all the ring plates 422 are damaged. At this time, the production is basically completed, that is, the wear is graded from the outside to the inside, thereby extending the service life.

[0067] Of course, in other embodiments, the heights of the plurality of ring plates 422 may not decrease sequentially from the outside to the inside, as long as the heights of the plurality of ring plates 422 are different, and there is no limitation to this.

[0068] Specifically, the open edge of the receiving hopper 421 is provided with a wear-resistant layer 423 to improve the wear resistance and extend the service life. The wear-resistant layer 423 can be made of alloy round steel.

[0069] Although the preferred embodiments of the present invention have been described, those skilled in the art may make other changes and modifications to these embodiments once they have learned the basic creative concept. Therefore, the appended claims are intended to be interpreted as including the preferred embodiments and all changes and modifications that fall within the scope of the present invention.

[0070] Obviously, those skilled in the art can make various changes and modifications to the present invention without departing from the spirit and scope of the present invention. Thus, if these modifications and variations of the present invention fall within the scope of the claims of the present invention and their equivalents, the present invention is also intended to include these modifications and variations.
