Description

Technical Field

[0001] This application relates to the field of material crushing, and in particular to a crusher. Background Technology

[0002] Crusher, also known as stone crusher, is a type of pulverizing machinery used in the processing of metal and non-metal ores to crush mined raw ore into small particles through compression and bending.

[0003] During operation, a conveying mechanism is typically used to transport the raw material to be crushed to the feed inlet of the crusher. The raw material continuously enters the crusher from the feed inlet for crushing, and the crushed material is discharged from the discharge outlet of the crusher.

[0004] However, when a large number of large pieces of raw material enter the crusher at the same time, the crusher may slow down the crushing speed. At this time, the conveying mechanism continues to convey raw material into the crusher, which may cause overflow at the feed inlet of the crusher. Summary of the Invention

[0005] In order to reduce the occurrence of material overflow in the crusher, this application provides a crusher.

[0006] The crusher provided in this application adopts the following technical solution:

[0007] A crusher includes a body, with a feed pipe fixedly connected to the upper end of the body. A conveying mechanism for conveying raw materials into the feed pipe is provided on one side of the body. A diversion mechanism is installed on the feed pipe, and a diversion port is opened on the inner side wall of the feed pipe. The diversion mechanism includes a transition pipe that is obliquely spiraled and fixed to the outer side wall of the body. One end of the transition pipe is fixedly connected to the diversion port, and the other end is fixedly connected to a storage box. A conveying mechanism for conveying the raw materials in the storage box to the feed pipe is connected to the storage box.

[0008] By adopting the above technical solution, the conveying mechanism transports the raw material to be crushed into the feed pipe. The raw material then enters the machine body along the feed pipe for crushing. When the crushing speed within the machine body is slow, the amount of raw material accumulating in the feed pipe gradually increases. When the raw material accumulates to the diversion port, it enters the transition pipe along the diversion port and then into the storage bin for collection. During the crushing process, the crusher vibrates, which facilitates the vibration of the feed pipe and the transition pipe. This facilitates the entry of the raw material in the feed pipe into the diversion port and allows the raw material in the transition pipe to slide closer to the storage bin. Once the raw material in the feed pipe successfully enters the machine body for crushing, the conveying mechanism transports the raw material from the storage bin back to the feed pipe. This reduces the occurrence of material overflow in the crusher.

[0009] Preferably, the conveying mechanism includes a conveying pipe fixed to and communicating with the upper surface of the storage box, the upper end of the conveying pipe extending to the upper opening of the feed pipe, an auger shaft provided inside the conveying pipe, auger blades fixedly connected to the outer side wall of the auger shaft, one end of the auger shaft extending into the storage box and rotatably connected to the bottom wall of the storage box, and a conveying motor for driving the auger shaft to rotate is installed on the storage box.

[0010] By adopting the above technical solution, the feeding motor is started, which drives the auger shaft to rotate. The rotation of the auger shaft drives the auger blades to rotate. At this time, the raw material in the storage box re-enters the feed pipe along the feeding pipe.

[0011] Preferably, the end of the transition pipe near the diversion port is fixed and connected to a diversion pipe, the end of the diversion pipe away from the transition pipe is connected to the diversion port and fixedly connected to the feed pipe, and the diversion pipe is gradually widened towards the diversion port.

[0012] By adopting the above technical solution, the design of the diversion pipe facilitates the smooth entry of raw materials into the diversion pipe along the diversion port, thereby smoothly entering the transition pipe.

[0013] Preferably, the machine body is equipped with a dust removal mechanism, which includes a partition plate fixed inside the transition pipe. The partition plate divides the transition pipe into a dust removal channel and a material storage channel. One end of the material storage channel is connected to a diversion port, and the other end is connected to a material storage box. One end of the dust removal channel is connected to the diversion port, and the other end is equipped with a dust collection mechanism for collecting dust. An exhaust fan for sucking air into the dust removal channel is installed on the transition pipe.

[0014] By adopting the above technical solution, the raw material enters the storage channel along the diversion port and is then collected in the storage bin along the storage channel. Simultaneously with the crusher's operation, the exhaust fan is activated. At this time, the dust generated at the feed inlet enters the dust removal channel along the diversion port and is then collected in the dust collection mechanism, facilitating the collection of dust generated at the feed pipe.

[0015] Preferably, a filter screen plate that blocks one end of the dust removal channel is fixedly connected to one end of the transition pipe near the diversion port. A vent is opened on one side wall of the transition pipe. An air suction pipe and an exhaust pipe are installed on the air extraction fan. One end of the air suction pipe is connected to the vent and fixed to the transition pipe. A filter plate that blocks the vent is fixedly connected to the vent.

[0016] By adopting the above technical solution, the filter screen is used to restrict the raw materials from entering the dust removal channel from one end, while the filter screen is set to prevent dust from entering the exhaust fan and causing damage to the exhaust fan.

[0017] Preferably, a dust collection port is provided on one side wall of the transition tube, and the dust collection mechanism includes a dust collection box that passes through the dust collection port and is inserted into the dust removal channel. An inlet is provided on one end face of the dust collection box away from the storage box. A fixing plate that blocks the dust collection port is fixedly connected to the upper surface of the dust collection box, and the fixing plate is connected to the transition tube by fasteners.

[0018] By adopting the above technical solution, during the operation of the exhaust fan, the dust entering the dust removal channel eventually moves to the dust collection box for collection. When it is necessary to clean the dust in the dust collection box, the fixing plate and the transition pipe are disassembled and separated by fasteners. Then, the fixing plate is pulled away from the transition pipe, and the fixing plate drives the dust collection box to detach from the transition pipe at the dust collection port, which facilitates the cleaning of the dust in the dust collection box.

[0019] Preferably, the dust removal channel is equipped with multiple striking mechanisms. Each striking mechanism includes a support rod fixed inside the dust removal channel, a rotating shaft rotatably connected to the support rod, a fan wheel fixedly connected to one end of the rotating shaft, a pull rope fixedly connected to the other end, and a striking block fixedly connected to the end of the pull rope away from the rotating shaft.

[0020] By adopting the above technical solution, when the exhaust fan is started, the air in the dust removal channel moves towards the dust collection box, and each impeller rotates under the action of the wind. The rotation of the impeller drives the shaft to rotate, and the rotation of the shaft drives the pull rope and the striking block to rotate. During the rotation, the striking block continuously strikes the partition plate, which facilitates the smooth sliding of the raw materials in the storage channel towards the storage box.

[0021] Preferably, one outer wall of the transition tube has multiple mounting ports, and the striking mechanism further includes a mounting plate that contacts the outer wall of the transition tube and seals the corresponding mounting ports. The mounting plate is connected to the transition tube by fasteners, and the end of the support rod away from the rotating shaft is fixedly connected to the corresponding mounting plate.

[0022] By adopting the above technical solution, the mounting plate and the transition tube are disassembled and separated by fasteners. By pulling the mounting plate away from the mounting port, the mounting plate can drive the striking mechanism to detach from the dust removal channel at the mounting port, which facilitates the maintenance of the striking mechanism.

[0023] In summary, this application includes at least one of the following beneficial technical effects:

[0024] 1. Reduce the occurrence of material overflow in the crusher;

[0025] 2. Facilitates the collection of dust generated at the feed pipe;

[0026] 3. The striking block continuously strikes the partition plate during rotation, which facilitates the smooth sliding of raw materials in the storage channel towards the storage box. Attached Figure Description

[0035] The following is in conjunction with the appendix Figures 1-7 This application will be described in further detail.

[0036] This application discloses a crusher. (Refer to...) Figure 1The crusher includes a support frame 1 and a machine body 2. The support frame 1 is fixedly connected to the machine body 2 and is used to support the machine body 2. The machine body 2 is equipped with a crushing mechanism for crushing materials. A feed pipe 21 is fixedly connected to the upper end of the machine body 2. The upper end face of the feed pipe 21 is open, and the lower end of the feed pipe 21 communicates with the inside of the machine body 2.

[0037] The lower end of the machine body 2 is fixedly connected to the feeding pipe 22. A conveying mechanism 3 is provided on one side of the machine body 2. The conveying mechanism 3 extends towards the feeding pipe 21, and one end of the conveying mechanism 3 is located directly above the feeding pipe 21. In this embodiment, the conveying mechanism 3 is a conveyor belt.

[0038] During operation, the raw material is conveyed to the feed pipe 21 along the conveying mechanism 3, and then enters the machine body 2 along the feed pipe 21. It is crushed in the machine body 2 by the crushing mechanism, and the crushed raw material is discharged along the discharge pipe 22.

[0039] Reference Figure 1 and Figure 2 To reduce the occurrence of material overflow at the feed pipe 21, a diversion mechanism 4 is installed on the machine body 2. The diversion mechanism 4 includes a diversion pipe 41 fixedly connected to the outer wall of the feed pipe 21. A diversion port 211 is opened on the inner wall of the feed pipe 21, and the diversion port 211 penetrates through the side wall of the feed pipe 21. One end of the diversion pipe 41 is connected to the diversion port 211, and the other end is fixedly connected to a transition pipe 42. The transition pipe 42 is spiraled downwards on the outer wall of the machine body 2 and is fixedly connected to the outer wall of the machine body 2. The end of the transition pipe 42 away from the diversion pipe 41 is fixedly connected to a storage tank 43. A conveying mechanism 5 is installed on the storage tank 43 for re-transferring the material in the storage tank 43 back into the feed pipe 21.

[0040] When the raw material in the feed pipe 21 accumulates until it reaches the diversion port 211, some of the raw material will enter the diversion pipe 41 along the diversion port, and then enter the storage box 43 for temporary storage along the inclined transition pipe 42. Since the crusher will vibrate when it is working, the feed pipe 21 fixed on the machine body 2 and the transition pipe 42 coiled and fixed on the machine body 2 will also vibrate accordingly. In this way, the raw material is easily vibrated and enters the diversion pipe 41, and it is also easy for the raw material to slide smoothly along the transition pipe 42 into the storage box 43.

[0041] The diversion pipe 41 gradually widens in the direction close to the diversion port 211, which facilitates the smooth entry of the raw material in the feed pipe 21 into the diversion pipe 41.

[0042] The material conveying mechanism 5 includes a conveying pipe 51 fixed to the upper surface of the storage box 43, which communicates with the interior of the storage box 43. The conveying pipe 51 extends upward to the upper opening of the feed pipe 21 and is fixedly connected to a discharge pipe 52. The discharge pipe 52 bends relative to the conveying pipe 51 towards the interior of the feed pipe 21, and gradually slopes downward towards the feed pipe 21. The discharge pipe 52 is fixedly connected to the feed pipe 21. An auger shaft 53 is rotatably connected to the inner bottom wall of the storage box 43. The auger shaft 53 extends upward into the conveying pipe 51, and its upper end extends into the discharge pipe 52. Auger blades 54 are fixedly wound around the side wall of the auger shaft 53. A conveyor motor 55 is fixedly connected to the outer bottom wall of the storage box 43, and the output shaft of the conveyor motor 55 is coaxially fixed with the lower end of the auger shaft 53.

[0043] Start the conveyor motor 55. The output shaft of the conveyor motor 55 drives the auger shaft 53 to rotate. The rotation of the auger shaft 53 drives the auger blades 54 to rotate. In this way, the auger blades 54 can send the raw material of the storage box 43 into the feed pipe 21 along the conveying pipe 51 and the discharge pipe 52.

[0044] When the crusher is working, a large amount of dust will be generated at the opening of the feed pipe 21. In order to reduce the dust at the opening of the feed pipe 21, a dust removal mechanism 6 is installed on the machine body 2.

[0045] Reference Figure 3 and Figure 4 The dust removal mechanism 6 includes a partition plate 61 fixedly connected inside the transition tube 42, the partition plate 61 extending spirally along the length of the transition tube 42. (See reference...) Figure 4 and Figure 5 The partition plate 61 divides the transition pipe 42 into a dust removal channel 611 and a storage channel 421, which are set up vertically. One end of the storage channel 421 is connected to the storage box 43. A dust collection mechanism 7 for collecting dust is installed at the end of the dust removal channel 611 near the storage box 43.

[0046] Reference Figure 3 and Figure 5 A filter plate 62, which blocks one end of the dust removal channel 611, is fixedly connected to one end of the transition pipe 42 near the diversion pipe 41. An exhaust fan 63 is fixedly connected to the outer wall of the transition pipe 42, located near the storage box 43. The exhaust fan 63 is equipped with a suction pipe 64 and an exhaust pipe 65. An air hole 422 communicating with the dust removal channel 611 is opened on one outer wall of the transition pipe 42. One end of the suction pipe 64 is fixedly connected to the air outlet and communicates with the air hole 422. A filter plate 66, which blocks the air hole 422, is fixedly connected to it.

[0047] When the exhaust fan 63 is started, the dust from the feed pipe 21 passes through the filter screen 62 and enters the dust removal channel 611. Subsequently, the dust enters the dust collection mechanism 7 along the dust removal channel 611 for collection. The filter screen 66 reduces the occurrence of dust entering the exhaust fan 63.

[0048] A dust collection port 423 is provided on the upper surface of the transition pipe 42, located at the end of the transition pipe 42 near the storage box 43. The dust collection mechanism 7 includes a dust collection box 71, with a fixing plate 72 fixedly connected to the upper surface of the dust collection box 71, and a handle 73 installed on the upper surface of the fixing plate 72. The dust collection box 71 passes through the dust collection port 423 and is inserted into the dust removal channel 611. The outer bottom wall of the dust collection box 71 abuts against the upper surface of the partition plate 61, and one outer side wall of the dust collection box 71 abuts against one outer side wall of the storage box 43. An inlet 711 is provided at the end of the dust collection box 71 away from the storage box 43. The bottom surface of the fixing plate 72 is in close contact with the upper surface of the transition pipe 42, thereby sealing the dust collection port 423. The fixing plate 72 and the transition pipe 42 are fastened together by screws.

[0049] The dust entering the dust removal channel 611 eventually passes through the inlet 711 and enters the dust collection box 71 for collection. When it is necessary to clean the dust in the dust collection box 71, turn the screw to disengage it from the fixing plate 72 and the transition tube 42, and pull the handle 73 away from the transition tube 42. The handle 73 drives the fixing plate 72 and the dust collection box 71 to gradually pass through the dust collection port 423 and disengage from the dust removal channel 611, which facilitates the cleaning of the inside of the dust collection box 71.

[0050] Reference Figure 5 and Figure 6 In order to facilitate the smooth movement of raw materials along the storage channel 421 into the storage box 43, a knocking mechanism 8 with multiple knocking partitions 61 is installed in the dust removal channel 611.

[0051] Reference Figure 6 and Figure 7 Each striking mechanism 8 includes a support rod 81 fixed within the dust removal channel 611, with a rotating shaft 82 rotatably connected to one end of the support rod 81. A fan wheel 83 is coaxially fixedly connected to one end of the rotating shaft 82, and a pull rope 84 is fixedly connected to the other end. A striking block 85 is fixedly connected to the end of the pull rope 84 away from the rotating shaft 82. The striking block 85 is an elastic block to reduce noise generation.

[0052] When the exhaust fan 63 is started to remove dust, the air flows rapidly along the dust removal channel 611. At this time, the wind blows each impeller 83 to rotate. The rotation of the impeller 83 drives the rotating shaft 82 to rotate. The rotation of the rotating shaft 82 drives the striking block 85 to continuously strike the partition plate 61.

[0053] The total length of the pull rope 84 and the striking block 85 is less than the distance between the side wall of the rotating shaft 82 and the upper inner wall, left inner wall, and right inner wall of the dust removal channel 611, respectively. The total length of the pull rope 84 and the striking block 85 is greater than the distance between the side wall of the rotating shaft 82 and the lower inner wall of the dust removal channel 611. Thus, when the rotating shaft 82 drives the pull rope 84 and the striking block 85 to rotate, the striking block 85 only strikes the partition plate 61. The partition plate 61 vibrates, which facilitates the movement of raw materials along the storage channel 421 and reduces the possibility of the elastic block striking other inner walls of the dust removal channel 611, thereby reducing the possibility of damage to the striking block 85.

[0054] The upper surface of the transition tube 42 has multiple mounting ports 424, each corresponding to a striking mechanism 8. The striking mechanism 8 also includes a mounting plate 86 disposed at the mounting port 424, which abuts against the upper surface of the transition tube 42 and seals the mounting port 424. The support rod 81 is fixedly connected to the bottom surface of the mounting plate 86, and the mounting plate 86 is fastened to the transition tube 42 by several fastening screws.

[0055] Rotate the screws on the mounting plate 86 until the mounting plate 86 can be detached from the transition tube 42. Pull the mounting plate 86 away from the transition tube 42. The mounting plate 86 will cause the striking mechanism 8 to disengage from the dust removal channel 611, which will facilitate the maintenance of the striking mechanism 8.

[0056] The implementation principle of a crusher according to an embodiment of this application is as follows: During operation, the raw material is conveyed to the feed pipe 21 along the conveying mechanism 3, and then enters the machine body 2 for crushing. The machine body 2 vibrates during the crushing process. When the raw material accumulates in the feed pipe 21 until it reaches the height of the diversion port 211, the raw material enters the storage channel 421 along the diversion port 211 and then enters the storage box 43 for collection. When the raw material in the feed pipe 21 smoothly enters the machine body 2, the conveying motor 55 is started. At this time, the raw material in the storage box 43 re-enters the feed pipe 21 along the conveying pipe and the discharge pipe 52.

[0057] While the crusher is working, the exhaust fan 63 is started. Dust passes through the filter screen 62 and enters the dust removal channel 611, and is collected in the dust collection box 71 along the dust removal channel 611. At the same time, the impeller 83 rotates under the action of wind. The rotation of the impeller 83 drives the rotating shaft 82 to rotate. The rotation of the rotating shaft 82 drives the striking block 85 to continuously strike the partition plate 61.

[0058] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
