Description

Technical Field

[0001] This utility model relates to the field of coal bunker equipment technology, specifically to a modular detachable hopper discharge port. Background Technology

[0002] In the fields of coal mining, processing, storage, and transportation, coal bunkers serve as core equipment for temporary coal storage and transshipment. Their discharge outlets are crucial nodes connecting the bunkers to downstream conveying systems, determining the continuity and stability of coal transportation. During long-term operation, the coal bunker discharge outlets must continuously withstand the impact of falling coal. In particular, lump coal and hard coal falling from the top of the bunker under gravity will generate high-frequency, high-energy impact loads on the inner wall of the discharge outlet.

[0003] To extend the service life of the discharge port, existing technologies commonly employ a lining method on the inner wall of the discharge port for protection. Current linings are mostly fixed to the discharge port body by integral welding or bolt fastening. However, the lining can be damaged during prolonged use. Once damaged, the steel plate of the discharge port body, which is not protected by the lining, will be worn down, leading to coal leakage and blockage at the discharge port, forcing the production line to shut down for maintenance.

[0004] Regarding the aforementioned technologies, when a local lining is damaged by impact, if the lining is an integral welded structure, the entire lining needs to be cut and removed, which will not only damage the steel plate of the discharge port body, but also generate a large amount of cutting waste; if the lining is a bolted structure, the bolt holes are easily blocked by coal dust, and the bolts are prone to corrosion and loosening after long-term vibration and impact, making disassembly time-consuming and labor-intensive, affecting replacement efficiency. Utility Model Content

[0005] In view of the above situation and to overcome the defects of the prior art, this utility model provides a modular and detachable hopper discharge port.

[0006] A modular, detachable hopper discharge port includes an upper coal hopper and a lower coal hopper. A discharge bin is fitted to the inner wall of the lower coal hopper, and the bottom of the lower coal hopper protrudes inward. The discharge bin is suspended from the bottom of the lower coal hopper. A first liner is slidably connected to the inner wall of the discharge bin, and a filler block is slidably connected between two adjacent first liners. A second liner is slidably connected to the inner wall of the discharge bin, and the first liner and the second liner abut against each other. A replacement channel for sliding the first liner is provided on the upper coal hopper. A replacement plate is slidably connected in the replacement channel, and the bottom of the replacement plate abuts against the top of the first liner. A filler block is fitted between two adjacent replacement plates.

[0007] Preferably, the lower coal bunker is an inverted truncated pyramid shape, the first liner is provided in four parts with two adjacent first liners abutting each other, and the top of the first liner is fixedly connected with a first locking block, and the bottom of the replacement plate is provided with a first locking groove that cooperates with the first locking block.

[0009] Preferably, the replacement plate includes a first connecting plate and a second connecting plate fixedly connected to the first connecting plate. The first connecting plate can block the replacement channel, and the width of the bottom of the second connecting plate is equal to the thickness of the first liner.

[0010] Preferably, the second connecting plate is inclined on the side closer to the interior of the upper coal bunker.

[0011] Preferably, the upper coal bunker is provided with a locking mechanism near the replacement channel to restrict the movement of the replacement plate.

[0012] Preferably, the locking mechanism includes a fixed rod fixedly connected to the lower part of the outer side wall of the upper coal bunker, a locking rod rotatably connected to the outer side of the fixed rod, and the locking rod abutting against the outer side wall of the upper coal bunker.

Detailed Implementation

[0019] The foregoing and other technical contents, features and effects of this utility model are described in conjunction with the appendix below. Figures 1 to 6 As will be clearly shown in the detailed description of the embodiments, the structural contents mentioned in the following embodiments are all with reference to the accompanying drawings.

[0020] Example 1: A modular, detachable hopper discharge port, referring to... Figure 1 , Figure 2 , Figure 3 and Figure 7The system includes an upper coal bunker 1 and a lower coal bunker 11 for transporting coal. The upper coal bunker 1 is not limited to the length shown in the attached drawings. The upper coal bunker 1 is generally rectangular. A material discharge bin 2 is fitted to the inner wall of the lower coal bunker 11. The top of the material discharge bin 2 abuts against the inner wall of the upper coal bunker 1. The bottom of the lower coal bunker 11 protrudes from the center of the lower coal bunker 11, thus forming a rectangular frame. A material discharge bin 21 is suspended on the frame at the bottom of the lower coal bunker 11. A first inner liner 3 is slidably connected to the inner wall of the material discharge bin 2. The first inner liner 3 abuts against the inner wall of the material discharge bin 2. A second inner liner 4 is slidably connected to the inner wall of the material discharge bin 21. A replacement channel 5 is provided on the upper coal bunker 1 for the first inner liner 3 to slide. A replacement plate 6 is slidably connected in the replacement channel 5. The bottom of the replacement plate 6 abuts against the top of the first inner liner 3. A filling block 33 is fitted between two adjacent replacement plates 6. The filling block 33 can seal the gap between adjacent replacement plates 6.

[0021] Specifically, when the discharge port needs protection, the first liner 3 and the second liner 4 can protect the side walls of the discharge bin 2 and the feed bin 21 to withstand the impact of coal during transportation, thereby extending their service life. When the damaged first liner 3 or second liner 4 needs to be replaced, the replacement plate 6 is first pulled out, and then the first liner 3 is pulled out by suction cup or clamp. The second liner 4 is lifted and moved out for replacement, which facilitates the replacement of the first liner 3 and the second liner 4, makes it easier for workers to operate, improves the safety of replacement, and also helps to improve the efficiency of replacement.

[0022] Example 2, refer to Figure 1 , Figure 2 , Figure 3 and Figure 4 The lower coal bunker 11 is shaped like an inverted truncated pyramid. There are four first inner liners 3, with two adjacent first inner liners 3 abutting each other. The four first inner liners 3 can cover the inner wall of the material drop hopper 2 to withstand the impact of coal. The top of the first inner liner 3 is fixedly connected to a first locking block 31, and the bottom of the replacement plate 6 is provided with a first locking groove 32 that cooperates with the first locking block 31.

[0023] Specifically, when it is necessary to improve the stability between the first inner liner 3 and the replacement plate 6, during the process of installing the first inner liner 3 and pushing the replacement plate 6 in, the first locking block 31 and the first locking groove 32 can make the connection between the first inner liner 3 and the replacement plate 6 tighter. When the replacement plate 6 is subjected to the impact of coal, it can improve the stability of the replacement plate 6 and protect the top of the first inner liner 3, thereby extending the service life of the first inner liner 3.

[0024] Example 3, referring to Figure 3The replacement channel 5 is tilted, and the bottom of the replacement channel 5 is on the same plane as the bottom of the first inner lining 3, and the tilt angle of the replacement channel 5 is equal to the tilt angle of the first inner lining 3.

[0025] Specifically, the inclined setting of the replacement channel 5 can reduce the opening size at the upper coal bunker 1, thereby saving costs. When the first inner liner 3 is removed, the first inner liner 3 can slide along the bottom wall of the replacement channel 5 to facilitate the removal of the first inner liner 3.

[0026] Example 4, refer to Figure 3 The replacement plate 6 includes a first connecting plate 61 and a second connecting plate 62 fixedly connected to the first connecting plate 61. The first connecting plate 61 can block the replacement channel 5, that is, the first connecting plate 61 and the replacement channel 5 are the same size and shape. The width of the bottom of the second connecting plate 62 is equal to the thickness of the first inner liner 3, thereby protecting the top of the first inner liner 3 and extending its service life. Since the top of the first inner liner 3 is trapezoidal and the two adjacent second connecting plates 6 will overlap when they abut against the first inner liner 3, the bottom sides of the second connecting plate 6 are cut off so that the bottom of the second connecting plate 6 is trapezoidal and the two adjacent second connecting plates 6 remain in abutting state.

[0027] Specifically, the first connecting plate 61 can block the replacement channel 5 to prevent coal from falling out of the replacement channel 5, thus ensuring the normal operation of coal conveying. The second connecting plate 62 can protect the top of the first inner liner 3 and can also withstand the impact of coal to protect the discharge port.

[0028] Example 5, refer to Figure 3 The second connecting plate 62 is inclined on one side near the inside of the upper coal bunker 1.

[0029] Specifically, the second connecting plate 62 is inclined on the side closest to the inside of the upper coal bunker 1, which can better guide the coal to fall while protecting the first inner lining 3, so as to facilitate the normal operation of coal transportation.

[0030] Example 6, refer to Figure 1 A locking mechanism 7 for restricting the movement of the replacement plate 6 is provided near the replacement channel 5 in the upper coal bunker 1.

[0031] Specifically, the locking mechanism 7 prevents the replacement plate 6 from moving during the impact of coal, thus making the replacement plate 6 more stable during coal transportation and improving the stability of the replacement plate 6 during coal transportation.

[0032] Example 7, referring to Figure 1 and Figure 5 The locking mechanism 7 includes multiple fixed rods 71 ​​fixedly connected to the lower part of the outer wall of the upper coal bunker 1. Each fixed rod 71 is rotatably connected to a locking rod 72 on its outer side. The locking rod 72 abuts against the outer wall of the upper coal bunker 1. After the locking rod 72 rotates, it can abut against the replacement plate 6 and block the replacement plate 6.

[0033] Specifically, when it is necessary to lock the replacement plate 6, rotating the locking rod 72 to contact the replacement plate 6 keeps the locking rod 72 in a vertical state, which can block the replacement plate 6, thereby reducing the probability of the replacement plate 6 popping out when impacted by coal and improving the stability of coal transportation.

[0034] Example 8, referring to Figure 3 A handle 63 is fixedly connected to the side wall of the replacement plate 6.

[0035] Specifically, the handle 63 allows staff to easily pull out the replacement plate 6 for replacing the first liner 3.

[0036] Example 9, referring to Figure 6 The feeding bin 21 abuts against the first inner liner 3, and the second inner liner 4 is suspended on the top of the feeding bin 21.

[0037] Specifically, by abutting the feed hopper 21 against the first inner lining 3, the gap between the two can be reduced, decreasing the probability of coal getting stuck at this position, which is conducive to the normal operation of coal conveying.

[0038] Example 10, referring to Figure 3 and Figure 6 The first locking block 31 is tilted, and the tilt angle of the first locking block 31 is the same as that of the first inner lining 3.

[0039] Specifically, by tilting the first locking block 31, while ensuring its stability, it is easy to pull out the first inner liner 3 when it is replaced, which is beneficial to the operation of the staff.

[0040] The working principle of a modular detachable hopper discharge port is as follows: When the discharge port needs to be installed, the discharge hopper is first hoisted to the upper coal bin 1, then the discharge hopper 2 is lowered into the lower coal bin 11, and then the discharge hopper 21 is hoisted and suspended on the lower coal bin 11. When the discharge port needs to be protected by the first inner liner 3 and the second inner liner 4, the operator first pulls the handle 63 to pull out the replacement plate 6, then the first inner liner 3 is inserted from the replacement channel 5 and slides along the inner wall of the connecting bin 21 to protect the inner wall of the connecting bin 21. Then the replacement plate 6 is pushed into the replacement channel 5 and engaged with the first inner liner 3. Then the filling block 33 is hoisted in to seal the gap between the replacement plates 6 so that the coal conveying operation can proceed normally. Then the locking rod 72 is rotated to contact the replacement plate 6 and lock the replacement plate 6. Finally, the second inner liner 4 is hoisted down from above and suspended on the discharge bin 21 to protect the discharge port.

[0041] When it is necessary to replace the first inner liner 3 and the second inner liner 4, the operator first rotates the locking lever 72 to make the locking lever 72 rotate to the horizontal position, then pulls the handle 63 to pull out the replacement plate 6, then pulls out the damaged first inner liner 3 through the suction cup, then puts the new first inner liner 3 into the replacement channel 5, and then rotates the locking lever 72 to make it contact the replacement plate 6 to lock the replacement plate 6. When replacing the second inner liner 4, the second inner liner 4 is lifted from the material drop hopper 2 for replacement, which facilitates its replacement.

[0042] The above description is only for illustrating the present utility model. It should be understood that the present utility model is not limited to the above embodiments, and various modifications that conform to the concept of the present utility model are within the protection scope of the present utility model.
