Description

[0003] Bucket elevator is mainly composed of driving device, head device, tail device, middle casing, bucket and chain (or belt).

DETAILED DESCRIPTION

[0039] The technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention; it is obvious that the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments, and all other embodiments obtained by ordinary technicians in this field based on the embodiments of the present invention without making creative work are within the scope of protection of the present invention.

[0040] See also Figures 1 to 10A bucket elevator for cement production comprises a protective shell 1, drive motors 14 are installed at both upper and lower ends of the outer part of the protective shell 1, a feed hopper 11 is fixedly installed at the bottom end of the protective shell 1, a discharge hopper 12 is fixedly installed at the top end of the protective shell 1, the feed hopper 11 and the discharge hopper 12 are installed along the tangent direction of both ends of the protective shell 1, a plurality of mounting frames 13 for supporting the protective shell 1 and the drive motor 14 are fixedly installed on the outer part of the protective shell 1, an internal bracket 2 is fixedly installed at the middle position of the inner part of the protective shell 1, transmission components 3 are installed at the upper and lower ends of the inner part of the protective shell 1 corresponding to the mounting frame 13, two first transmission chains 4 are arranged inside the protective shell 1, the first transmission chain 4 is used to transmit the two transmission components 3, and a plurality of evenly distributed conveying components 5 are installed on the first transmission chain 4.

[0041] During actual use, the drive motor 14 is first controlled to work. When the drive motor 14 is working, it will drive the two transmission components 3 to work. When the transmission components 3 are working, they will drive the two first transmission chains 4 to transmit. Because the conveying component 5 is fixedly installed on the first transmission chain 4, when the first transmission chain 4 is transmitted, it will drive the conveying component 5 to convey. At this time, the material is transported into the interior of the feed hopper 11, and the conveying component 5 can load the material from the feed hopper 11 and throw the material out from the position of the discharge hopper 12, so as to realize the lifting and transportation of the material.

[0042] The transmission component 3 includes a first transmission gear 31 and a second transmission gear 32 that are symmetrical to each other. The two first transmission chains 4 are respectively meshed with the two opposite first transmission gears 31 and the two opposite second transmission gears 32. A first center shaft 33 is fixedly connected between the first transmission gear 31 and the second transmission gear 32. A damping component 7 is rotatably sleeved on the outer surface of one end of the first center shaft 33 close to the first transmission gear 31. An alarm component 6 is fixedly installed on the side of the first transmission gear 31 away from the second transmission gear 32. A driving shaft 141 is fixedly installed on the driving end of the driving motor 14. The driving shaft 141 passes through the alarm component 6 and the first transmission gear 31 and extends into the interior of the first center shaft 33.

[0043] When the equipment is overloaded, the conveying component 5 is filled with excessive materials, which causes the force on the first transmission chain 4 to be greater than its carrying capacity, making it easy to break, or the resistance on the first transmission chain 4 is greater than the power provided by the drive motor 14, which can easily cause the drive motor 14 to be damaged or even burned. Therefore, the device is provided with a transmission component 3 and a damping component 7. When in use, if the material on the conveying component 5 exceeds its carrying weight, the transmission component 3 will automatically release the connection between the drive shaft 141 and the first transmission gear 31, causing the drive shaft 141 to idle, thereby preventing the first transmission chain 4 from breaking or the drive motor 14 from being damaged due to excessive load, thereby achieving self-protection.

[0044] A fixing rod 331 is fixedly installed at one end of the first central shaft 33 close to the second transmission gear 32. The fixing rod 331 is rotatably installed on the side wall of the protective shell 1. A threaded rod 332 is rotatably installed at the middle of the fixing rod 331. A threaded sleeve 333 is sleeved on the outside of the end of the threaded rod 332 away from the fixing rod 331 through a threaded fit. A first moving block 334 is fixedly installed at one end of the threaded sleeve 333 away from the threaded rod 332. The first moving block 334 is slidably clamped in the interior of the first central shaft 33. One end of the first moving block 334 away from the threaded sleeve 333 A second movable block 335 is provided on the side, and the second movable block 335 is slidably clamped inside the first central axis 33. A first spring 336 is fixedly connected between the second movable block 335 and the first movable block 334. One end of the driving shaft 141 extends into the interior of the first central axis 33 and fits with the second movable block 335. A plurality of evenly distributed mating teeth 1411 are integrally formed at one end of the driving shaft 141 close to the second movable block 335. A plurality of mating grooves 3351 used in conjunction with the mating teeth 1411 are opened at one end of the second movable block 335 close to the driving shaft 141.

[0045] When the device is working normally, under the action of the first spring 336, the matching tooth 1411 is tightly connected with the matching groove 3351. At this time, when the driving shaft 141 rotates, it can drive the second moving block 335 to rotate, and when the second moving block 335 rotates, it will drive the first central shaft 33 to rotate, and then drive the first transmission gear 31 and the first central shaft 33 to rotate. When the first transmission gear 31 and the second transmission gear 32 rotate, they will generate a transmission effect on the first transmission chain 4, and then control the conveying component 5 thereon to convey the material. When the material carried on the conveying component 5 is too much At this time, the resistance of the first transmission gear 31 and the second transmission gear 32 to the transmission of the first transmission chain 4 will also increase, which will cause the mating tooth 1411 and the mating groove 3351 to slip. At this time, the second moving block 335 is pushed to lose the connection with the drive shaft 141 to prevent the drive motor 14 and the first transmission chain 4 from being damaged by excessive tension. The threaded sleeve 333 can be moved by rotating the threaded rod 332, thereby controlling the thrust of the first spring 336 on the second moving block 335, which is used to control the connection strength between the drive shaft 141 and the second moving block 335, thereby adjusting the protection threshold of the device.

[0046] A plurality of evenly distributed connecting rods 338 are fixedly installed on the outer ring of the second moving block 335, a plurality of sliding grooves for the connecting rods 338 to slide are opened on the first central shaft 33, and the connecting rods 338 are slidably clamped in the corresponding sliding grooves, and a moving ring 337 is rotatably sleeved on the outer end of the first central shaft 33 close to the first transmission gear 31, and the end of the connecting rod 338 extends and is rotatably clamped in the inside of the moving ring 337, and a second central shaft 34 is provided on both sides of the first central shaft 33, and the second central shaft 34 is rotatably mounted on the internal bracket 2, A first gear 341 is fixedly installed on one end of the second center shaft 34 close to the first transmission gear 31, and a second gear 342 is fixedly installed on one end of the second center shaft 34 away from the first gear 341. Transmission is carried out between the multiple first gears 341 and the multiple second gears 342 through a second transmission chain 35. A sliding rod 343 is slidably clamped on one end of the first gear 341 away from the second center shaft 34, and a third gear 344 is fixedly installed on one end of the sliding rod 343 away from the first gear 341. The movable ring 337 is fixedly connected to the sliding rod 343.

[0047] When the driving shaft 141 loses connection with the second moving block 335, the second moving block 335 is pushed. When the second moving block 335 is pushed, the moving ring 337 is driven to move, and then the sliding rod 343 and the third gear 344 are driven to move. The movement of the third gear 344 will lose the connection with the damping component 7. When the third gear 344 loses the connection with the damping component 7, it can automatically drive the conveying component 5 to work from the normal transportation state to the overload protection state. When the conveying component 5 changes to the overload protection state, it can tilt and automatically unload the overloaded materials thereon, thereby reducing the load-bearing capacity of the conveying component 5 until the load-bearing capacity of the conveying component 5 is reduced to within the threshold value. At this time, the driving shaft 141 will drive the transmission component 3 to work again. The transport operation is restarted. When the device is in normal working state, the second moving block 335 drives the moving ring 337 to move under the action of the first spring 336, and then the moving ring 337 drives the slide bar 343 and the third gear 344 to move, so that the third gear 344 is reconnected with the damping component 7. At this time, the rotation of the first central axis 33 can drive the damping component 7 to rotate, and the rotation of the damping component 7 will drive the third gear 344 to rotate. The rotation of the third gear 344 will drive the first gear 341, the second central axis 34, and the second gear 342 to rotate synchronously, thereby driving the second transmission chain 35 to transmit. When the second transmission chain 35 transmits, the conveying component 5 will be driven from the overload protection state to the normal transportation state.

[0048] The damping component 7 includes a rotating ring 71, and a connecting gear 72 is fixedly installed on one side of the rotating ring 71 close to the moving ring 337. The rotating ring 71 and the connecting gear 72 are both rotatably sleeved on the outer surface of the first center shaft 33. A wave groove 73 is opened in the middle of the connecting gear 72, and a plurality of fixed sleeves 74 distributed in a ring shape are arranged inside the connecting gear 72. A sliding plate 75 is provided on the internal sliding card of the fixed sleeve 74. A second spring is fixedly connected between the sliding plate 75 and the fixed sleeve 74. A circular boss 76 is fixedly installed on the end of the sliding plate 75 away from the fixed sleeve 74, and the circular boss 76 fits with the surface of the wave groove 73.

[0049] When the device is working normally, the connecting gear 72 is meshed with the third gear 344. When the first central shaft 33 rotates, it will drive the fixed sleeve 74 and the sliding plate 75 to rotate. Because the circular convex head 76 is in contact with the wave groove 73, the rotation of the fixed sleeve 74 will generate resistance. Because the third gear 344 is meshed with the connecting gear 72, the first moving block 334 will rotate in the opposite direction to the connecting gear 72, which will cause the transmission direction of the second transmission chain 35 to be opposite to the transmission direction of the first transmission chain 4. The second transmission chain 35 is connected to the conveying component 5, so the movement of the conveying component 5 will generate resistance to the second transmission chain 35. At this time, the resistance of the third gear 344 to the connecting gear 72 increases, which in turn causes the circular convex head 76 to slide along the surface of the wave groove 73, that is, the driving shaft 141 cannot drive the rotating ring 71 and the connecting gear 72 to rotate. The resistance provided between the circular convex head 76 and the wave groove 73 is used to restore the conveying component 5 from the overload protection state to the normal transportation state, and to keep the conveying component 5 in the normal transportation state.

[0050] The conveying component 5 includes a fixed plate 51, which is fixedly installed on the first transmission chain 4. A hinged frame 52 is fixedly installed on the lower end of the fixed plate 51 on a side away from the first transmission chain 4. A transport bucket 53 is rotatably installed on the hinged frame 52. Two symmetrical protective gears 54 are fixedly installed on the lower end of the transport bucket 53 on a side close to the fixed plate 51. A groove body 56 for supplying the protective gear 54 to rotate is opened on the fixed plate 51. The protective gear 54 is coaxially arranged with the hinged frame 52, and the protective gear 54 is meshed with the corresponding second transmission chain 35. A plurality of evenly distributed telescopic rods 55 are provided on the upper end of the fixed plate 51 on a side close to the hinged frame 52, and the two ends of the telescopic rods 55 are rotatably installed on the fixed plate 51 and the transport bucket 53 respectively.

[0051] When the device is working normally, the conveying component 5 on one side is loaded with materials, while the conveying component 5 on the other side is not loaded with materials. When the first transmission chain 4 drives the conveying component 5 to transmit, the second transmission chain 35 and the first transmission chain 4 are reversely transmitted, which causes the protective gear 54 to be subjected to resistance to positive rotation, so that the transport bucket 53 fits with the fixed plate 51, and the conveying component 5 is in a normal transportation state, which can better transport materials. When the device is overloaded, because the first gear 341 drives the third gear 344 to lose engagement with the connecting gear 72, the connecting gear 72 loses its force on the third gear 344 and the first gear 341, that is, the second transmission chain 35 loses its resistance to the protective gear 54. At this time, the side loaded with materials The conveying component 5 will cause the transport bucket 53 and the protective gear 54 to rotate around the articulated frame 52 under the action of the gravity of the material, thereby causing the transport bucket 53 to tilt downward. At this time, the conveying component 5 is in an overload protection state. At this time, the material on the transport bucket 53 will fall to the inner bottom end of the protective shell 1 until the bearing capacity of all conveying components 5 is reduced to within the threshold value. The drive shaft 141 drives the first central axis 33 to rotate again, and the first central axis 33 drives the first transmission chain 4 to drive again, and the first transmission chain 4 will drive the conveying component 5 to move again. At this time, the connecting gear 72 and the third gear 344 are re-engaged, which means that the second transmission chain 35 is re-driven, so that the protective gear 54 regains resistance and then returns to a normal transportation state.

[0052] By providing a damping component 7, the device can automatically unload a portion of the material when the maximum load is exceeded until the device returns to a normal state, so that the device has the ability to automatically adjust the load and can achieve autonomous unloading without the need for workers to clean up when overloaded.

[0053] The device is provided with a second transmission chain 35 so that the device can automatically return to its original state after automatically unloading the material without disassembling the machine for resetting. Even if overloaded due to improper use, the device can be reset autonomously, thereby reducing the dependence of the device on workers and improving the degree of automation.

[0054] The alarm component 6 includes a fixed ring 61, which is fixedly mounted on the side surface of the first transmission gear 31, and is rotatably mounted on the side wall of the protective shell 1. A plurality of evenly distributed rotating plates 62 are provided on the side of the fixed ring 61 away from the first transmission gear 31, and the rotating plates 62 are rotatably mounted on the driving shaft 141. A plurality of evenly distributed sounding plates 64 are fixedly mounted at positions corresponding to the driving shaft 141 and the rotating plates 62. A metal ball 63 is fixedly mounted on the side of the rotating plate 62 away from the fixed ring 61, and the metal ball 63 and the sounding plate 64 are alternately arranged. A pleated groove 66 used in conjunction with the rotating plate 62 is provided on the side of the fixed ring 61 close to the rotating plate 62, and the rotating plate 62 is fitted with the pleated groove 66, and a torsion spring 65 is fixedly connected between the rotating plate 62 and the driving shaft 141.

[0055] When the device is working normally, the fixed ring 61 rotates synchronously with the driving shaft 141, and the rotating plate 62 does not rotate. The metal ball 63 and the sounding plate 64 are in a relatively static state. When the device is overloaded, because the first transmission gear 31 stops rotating and the fixed ring 61 is fixedly installed on the first transmission gear 31, the fixed ring 61 also stops rotating, while the driving shaft 141 still rotates. At this time, the driving shaft 141 drives the rotating plate 62 to revolve. One end of the rotating plate 62 is conical and fits with the pleated groove 66. Therefore, when the driving shaft 141 drives the rotating plate 62 to revolve, the rotating plate 62 is driven by the pleated groove 66 to rotate continuously, thereby causing the metal ball 63 to be driven to rotate. When the metal ball 63 rotates, it will knock on the sounding plate 64, thereby causing the sounding plate 64 to make a sound. Under the action of the torsion spring 65, the rotating plate 62 will be driven to rotate reciprocatingly, thereby continuously knocking on the sounding plate 64 to make a sound.

[0056] The device is provided with an alarm component 6 so that the device can automatically sound an alarm when it is overloaded, thereby preventing the device from continuously conveying materials to cause a vicious cycle and subsequent blockage, thereby ensuring the stability and safety of the device.

[0057] By providing a feed hopper 11, the device can not only be used for feeding, but also the conveying component 5 can unload the material inside the feed hopper 11 when overloaded. When the device is working again, the unloaded material will be re-transported by the empty conveying component 5, realizing autonomous cleaning and sustainable operation.

[0058] Working principle: When actually used, the driving motor 14 is controlled to work first. When the driving motor 14 works, it drives the two transmission components 3 to work. The transmission components 3 can drive the conveying components 5 to transport the materials;

[0059] When the transported material is overloaded, the conveying component 5 changes from the normal transport state to the overload protection state, and the transmission component 3 automatically releases the connection between the drive shaft 141 and the first transmission gear 31, so that the drive shaft 141 idles, which can prevent the first transmission chain 4 from breaking or the drive motor 14 from being damaged due to excessive load;

[0060] When the load on the conveying component 5 is reduced to within the threshold, the second moving block 335 drives the moving ring 337 to move under the action of the first spring 336, and drives the sliding rod 343 and the third gear 344 to move, so that the third gear 344 is reconnected with the damping component 7, and then the first central shaft 33 rotates to drive the damping component 7 to rotate and drive the third gear 344 to rotate, and the rotation of the third gear 344 drives the first gear 341, the second central shaft 34, and the second gear 342 to rotate synchronously, and then drives the second transmission chain 35 to transmit, so that the conveying component 5 can automatically change from the overload protection state to the normal transportation state;

[0061] When the conveying component 5 is in the overload protection state, the driving shaft 141 idles at this time, and when the driving shaft 141 idles, it drives the alarm component 6 to work and send a warning signal to the outside to remind the workers.

[0062] The above is only a preferred specific implementation of the present invention; however, the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes according to the technical solution and its improved conception within the technical scope disclosed by the present invention, which should be covered by the protection scope of the present invention.
