Description

Technical Field

[0001] The invention belongs to the field of coal conveying and receiving, and particularly relates to a buffer type coal receiving device for coal conveying. Background Art

[0002] In the processes of coal mining, transportation and processing, the conveying of coal is a key link. At present, a conveyor belt is usually used for receiving and conveying coal. Since the impact force when coal falls directly acts on the surface of the conveyor belt, it causes the conveyor belt to be worn more severely and shortens its service life. Therefore, a buffer bed is arranged at the bottom of the conveyor belt, and the impact energy when coal falls is absorbed through an elastic material or structure, so as to reduce the direct impact on the conveyor belt, protect the conveyor belt and extend its service life.

[0003] A plurality of elastic buffer strips are arranged at intervals on the existing buffer bed. When the conveyor belt conveys coal, it contacts the surface of the elastic buffer strips. The elastic buffer strips can buffer the conveyor belt, so as to realize buffer receiving of coal. However, when some of the elastic buffer strips on the buffer bed fail due to long-term use and need to be replaced, since the elastic buffer strips are in contact with the conveyor belt, it is easy to squeeze the conveyor belt when disassembling and removing the failed elastic buffer strips, affecting the use effect of the conveyor belt. Therefore, usually, the work of the conveyor belt needs to be stopped to replace the elastic buffer strips, resulting in the interruption of coal conveying operations and affecting production efficiency.

[0018] Compared with the prior art, a buffer coal receiving device for coal conveying provided by an embodiment of the present invention has the following

[0019] Advantageous effects:

[0020] 1. Through the cooperation of the elastic buffer strip and the auxiliary buffer mechanism, the present invention can buffer the conveyor belt when coal falls on the conveyor belt, ensuring the continuity and stability of the buffering effect on coal. Moreover, by using the cooperation of the fixing mechanism and the locking mechanism, the elastic buffer strip that needs to be replaced can be separately disassembled when the conveyor belt is working, so that the coal receiving work can be carried out continuously without affecting the production efficiency of coal.

[0021] 2. In the present invention, a fixing mechanism and a locking mechanism are provided.

Detailed implementation manners

[0034] The following is a further detailed description of the present application in conjunction with the attached Figure 1-9 drawings.

[0035] Please refer to Figure 1 and Figure 2 , a buffer coal receiving device for coal conveying, including a plurality of buffer mechanisms 2 arranged on the upper right side of the support frame 1 for reducing the impact force of coal. The buffer mechanism 2 includes three base plates 201 fixedly arranged on the upper right side of the support frame 1, and a plurality of mounting bases 202 are fixedly arranged on the upper parts of the three base plates 201 together. Two rectangular plates 203 symmetrically distributed left and right are slidably arranged on the upper parts of the mounting bases 202.

[0036] Referring to Figure 1 , a conveying mechanism 6 for conveying coal is arranged on the upper part of the support frame 1. The conveying mechanism 6 includes fixing plates 601 fixedly arranged at the four corners of the upper part of the support frame 1. Conveying rollers 602 are rotatably arranged between the corresponding two fixing plates 601. A conveyor belt 603 is arranged between the two conveying rollers 602, and the lower surface of the upper half of the conveyor belt 603 is in contact with the upper part of the elastic buffer strip 206. A motor 604 is fixedly arranged on one side of a fixing plate 601 away from the conveying roller 602, and the output shaft of the motor 604 is connected to one end of the corresponding conveying roller 602.

[0037] When receiving coal, the coal falls onto the conveyor belt 603. At this time, the buffer mechanism 2 can effectively buffer the impact force when the coal falls, reduce the direct impact on the conveyor belt 603, thereby protecting the conveyor belt 603 and extending its service life. Then, the motor 604 works to drive the conveying roller 602 to rotate, and the conveying roller 602 rotates to convey the coal on the conveyor belt 603 through the conveyor belt 603.

[0038] Referring toFigure 2 On the front and rear sides of the upper part of the support frame 1 and on the left side of the mounting base 202, a plurality of vertical plates 13 are fixedly arranged. A connecting support member 14 is fixedly arranged between two corresponding vertical plates 13. A plurality of support and limit rollers 15 are rotatably arranged on the outer side of the connecting support member 14. The connecting support member 14 is arranged to adapt to the curved rod shape of the buffer mechanism 2, and the lower surface of the upper half of the conveyor belt 603 is in contact with the outer side of the support and limit rollers 15.

[0039] To ensure the stability of the conveyor belt 603 during transportation, the support and limit rollers 15 will rotate when the conveyor belt 603 is working. By using the support and limit rollers 15, it can ensure that the conveyor belt 603 remains stable during operation, avoiding deviation or slipping of the conveyor belt 603. At the same time, a plurality of support and limit rollers 15 are evenly distributed below the conveyor belt 603, and can evenly disperse the weight of the coal to each part of the support frame 1, which can prevent damage to the conveyor belt 603 or the support frame 1 caused by excessive local stress.

[0040] Refer to Figure 2 Inside the rectangular plate 203, a support plate 204 is slidably arranged. The top end of the support plate 204 penetrates out of the inside of the rectangular plate 203. On the upper parts of two corresponding support plates 204, a top plate 205 is fixedly arranged together. An elastic buffer strip 206 is fixedly arranged on the upper part of the top plate 205. An auxiliary buffer mechanism 3 is fixedly arranged together with the rectangular plate 203 corresponding to the outer side and the left side of the elastic buffer strip 206.

[0041] Refer to Figure 3 The auxiliary buffer mechanism 3 includes an air pump 301 (the air pump 301 is a small air pump) fixedly arranged on the left side of the left rectangular plate 203. The air outlet end of the air pump 301 is communicated with a guide air pipe 302. A valve is arranged on the guide air pipe 302. A buffer airbag 303 is arranged on the outer side of the elastic buffer strip 206 through a buckle, and the end of the guide air pipe 302 far from the air pump 301 is communicated with the buffer airbag 303.

[0042] To improve the buffer effect when receiving coal, when the air pump 301 works to convey air into the guide air pipe 302, the buffer airbag 303 can be inflated, and then two adjacent buffer airbags 303 come into contact, so that a continuous buffer area is formed between a plurality of elastic buffer strips 206 and a plurality of buffer airbags 303. Thus, the gap between two elastic buffer strips 206 can be reduced, and further, the direct impact of coal on the gap area of the conveyor belt 603 is avoided (as Figure 9 shown). When the coal falls onto the conveyor belt 603, the conveyor belt 603 is in direct contact with the elastic buffer strip 206. The elastic buffer strip 206 can absorb the impact force when the coal falls, reduce the vibration and wear of the conveyor belt 603, and protect the conveyor belt 603 from local damage.

[0043] Refer toFigure 4 and Figure 5 On the front side of the buffer airbag 303, a hook surface 16 of a magic tape is fixedly arranged, and on the rear side of the buffer airbag 303, a fluffy surface 17 of a magic tape that is used in cooperation with the hook surface 16 of the magic tape is fixedly arranged. Two adjacent buffer airbags 303 are connected through the adhesion of the hook surface 16 of the magic tape and the fluffy surface 17 of the magic tape.

[0044] In order to improve the connection effect between two adjacent buffer airbags 303, when the two adjacent buffer airbags 303 expand and come into contact, the corresponding hook surface 16 of the magic tape and the fluffy surface 17 of the magic tape are tightly combined to form a connection, which can effectively prevent the separation of the two adjacent buffer airbags 303 caused by the impact force.

[0045] Refer to Figure 1 、 Figure 3 and Figure 6 Refer to , the mounting base 202 and the rectangular plate 203 jointly have a fixing mechanism 4 that is used in cooperation with the support plate 204. The fixing mechanism 4 includes two mounting plates 401 that are fixedly arranged on the upper part of the mounting base 202 and are symmetrically distributed left and right. A threaded sleeve 402 is rotatably arranged on the two mounting plates 401. The inside of the threaded sleeve 402 is provided with two threaded grooves with opposite thread directions, and two threaded rods 403 are threadedly connected to both threaded grooves. One end of the threaded rod 403 away from the threaded sleeve 402 is fixedly provided with an insertion rod 404. An L-shaped linkage 405 is fixedly arranged on the outer side of the threaded rod 403. One side of the L-shaped linkage 405 away from the threaded sleeve 402 is fixedly provided with a pressing wedge 406. One end of the pressing wedge 406 away from the L-shaped linkage 405 slides through the rectangular plate 203, and the bottom of the support plate 204 contacts the upper part of the pressing wedge 406.

[0046] Refer to Figure 6 and Figure 7 Refer to , a jack 7 that is used in cooperation with the insertion rod 404 is opened on one side of the support plate 204 close to the insertion rod 404. One end of the insertion rod 404 away from the threaded rod 403 penetrates into the inside of the rectangular plate 203 and is inserted into the jack 7.

[0047] Refer to Figure 3 and Figure 8 Refer to , a chute 8 is opened on the upper part of the mounting base 202. A slider that is slidably connected to the chute 8 is fixedly arranged at the bottom of the rectangular plate 203. The vertical cross-sections of the chute 8 and the slider 9 are both convex. Two locking holes 10 that communicate with the chute 8 are opened inside the mounting base 202.

[0048] Refer to Figure 6 and Figure 8, a locking mechanism 5 is jointly provided on the rectangular plate 203 and the mounting base 202 for cooperating with the fixing mechanism 4. The locking mechanism 5 includes a moving plate 501 slidably disposed inside the rectangular plate 203 and located at the lower end of the extrusion wedge block 406. The upper part of the moving plate 501 abuts against the bottom of the extrusion wedge block 406. A locking rod 502 is fixedly provided at the bottom of the moving plate 501. A spring 503 is sleeved outside the locking rod 502. The upper and lower ends of the spring 503 are respectively connected to the bottom end of the moving plate 501 and the inner wall of the rectangular plate 203. The bottom end of the locking rod 502 slidably penetrates out of the inside of the rectangular plate 203 and is inserted into the corresponding locking hole 10. The sides of the support plate 204 and the moving plate 501 close to each other and the upper and lower ends on the left side of the extrusion wedge block 406 are all in a slope shape for cooperation.

[0049] In order to facilitate the separate disassembly of the elastic buffer strip 206 that needs to be replaced when the conveyor belt 603 is working, when disassembling the elastic buffer strip 206 that needs to be replaced, first open the valve on the corresponding air duct 302, so that the gas in the corresponding buffer airbag 303 is discharged, thereby realizing its contraction. Subsequently, through an external force, the contracted buffer airbag 303 is separated from the adjacent buffer airbag 303. Then rotate the corresponding threaded sleeve 402. The rotation of the threaded sleeve 402 can drive two corresponding threaded rods 403 to approach each other. The movement of the threaded rod 403 can drive the insertion rod 404 to move out of the insertion hole 7, thus canceling the limit on the support plate 204. When the threaded rod 403 moves, it will also drive the extrusion wedge block 406 to move through the L-shaped linkage 405. When the extrusion wedge block 406 moves to a position where it does not contact the support plate 204 and the moving plate 501 (as Figure 8 shown), at this time, the supporting force received by the support plate 204 disappears, and at the same time, the extrusion force received by the moving plate 501 disappears. As a result, the support plate 204 will slide downward inside the rectangular plate 203. The downward movement of the support plate 204 can drive the elastic buffer strip 206 on the top plate 205 to move downward, so that the elastic buffer strip 206 is separated from the conveyor belt 603. At the same time, through the elastic force of the spring 503, the moving plate 501 can be driven to move upward. The upward movement of the moving plate 501 can drive the locking rod 502 to move upward and out of the locking hole 10, thus canceling the limit locking of the rectangular plate 203. Then, the corresponding rectangular plate 203 can be pulled to the left to make the corresponding elastic buffer strip 206 move, so that the elastic buffer strip 206 that needs to be replaced can be separately disassembled when the conveyor belt 603 is working.

[0050] Refer to Figure 9 and Figure 10, after the elastic buffer strip 206 that needs to be replaced is disassembled, at this time, the two air pumps 301 adjacent to the disassembly position start to work, and continue to inflate the corresponding buffer airbag 303 through the air duct 302 to make the buffer airbag 303 continue to expand. At this time, the two adjacent buffer airbags 303 are in contact, and are reconnected through the hook surface 16 of the magic tape and the fluffy surface 17 of the magic tape (as Figure 10 shown), to ensure the continuity and stability of the coal buffer effect, so it is not easy to affect the coal receiving.

[0051] Refer to Figure 7 , limiting ports 11 are provided on both the front and rear sides of the upper part of the rectangular plate 203, and limiting blocks 12 slidably connected to the limiting ports 11 are fixedly provided on both the front and rear sides of the support plate 204.

[0052] In order to prevent the support plate 204 from squeezing the moving plate 501 when it moves downward, the limiting block 12 will slide in the limiting port 11 when the support plate 204 moves downward. When the limiting block 12 moves downward to contact the limiting port 11, the support plate 204 stops moving downward. At this time, the bottom end of the support plate 204 does not contact the upper part of the moving plate 501 (as Figure 8 shown), so that the support plate 204 can be prevented from squeezing the moving plate 501 when it moves downward.

[0053] During specific operation, when receiving coal, the coal falls onto the conveyor belt 603. The conveyor belt 603 is in direct contact with the elastic buffer strip 206. The elastic buffer strip 206 can absorb the impact force when the coal falls, reduce the vibration and wear of the conveyor belt 603. At the same time, the auxiliary buffer mechanism 3 can reduce the gap between the two elastic buffer strips 206, thus avoiding the coal from directly impacting the gap area of the conveyor belt 603, and further protecting the conveyor belt 603 from local damage.

[0054] When the elastic buffer strip 206 that needs to be replaced needs to be disassembled separately, the corresponding buffer airbag 303 can be separated from the two adjacent buffer airbags 303 first, and then the threaded sleeve 402 is rotated. The rotation of the threaded rod 403 can drive the insertion rod 404 and the extrusion wedge block 406 to move. The movement of the insertion rod 404 cancels the locking of the support plate 204. The movement of the extrusion wedge block 406 can make the support plate 204 move downward while making the locking rod 502 move out of the locking hole 10, so that the corresponding rectangular plate 203 can be pulled to the left to make the corresponding elastic buffer strip 206 move, and the elastic buffer strip 206 does not contact the conveyor belt 603, so that the elastic buffer strip 206 that needs to be replaced can be disassembled separately when the conveyor belt 603 is working.

[0055] Moreover, after the elastic buffer strip 206 that needs to be replaced is disassembled, at this time, the two air pumps 301 adjacent to the disassembly position start to work, and continue to inflate the corresponding buffer airbag 303 through the air duct 302 so that the buffer airbag 303 continues to expand, enabling the two adjacent buffer airbags 303 to be reconnected, ensuring the continuity and stability of the buffering effect, and thus it is not easy to affect the coal receiving.

[0056] The above are only the embodiments of the present invention, and do not limit the patent scope of the present invention accordingly. Any equivalent structure or equivalent process transformation made by using the content of the specification and drawings of the present invention, or directly or indirectly applied in other related technical fields, shall be equally included in the patent protection scope of the present invention.
