For ordinary technicians in this field, the specific meanings of the above terms in the present utility model can be understood according to specific circumstances. In addition, the technical features involved in the different embodiments of the present utility model described below can be combined with each other as long as they do not conflict with each other.

[0041] Please refer to Figures 1 to 5 The preferred embodiment of the utility model provides an automatic adjustment system for material transmission of an impact crusher, which mainly includes a feeding hopper 10, a vibration motor 20, a crushing mechanism 30, a main conveyor belt 40, an iron remover 50, an angle sensor 60, a baffle 61 and a control system.

[0042] The feed hopper 10, the vibration motor 20, the crushing mechanism 30, the main conveyor belt 40, the iron remover 50, the angle sensor 60, the baffle 61 and the control system are installed on the impact crushing station, specifically on the frame assembly 100 of the impact crushing station. The frame assembly 100 is composed of steel plates and crawlers, etc., and is mainly responsible for the support and movement of the whole machine to realize a crawler-type impact crushing station. The impact crushing station is also provided with a power assembly 200, which mainly includes a power box and an oil extraction machine and a generator located inside the power box. The oil extraction machine drives the generator to operate to generate electricity, and the electric energy supplies energy to the vibration motor 20, the crushing mechanism 30, the main conveyor belt 40, the iron remover 50, the angle sensor 60 and other driving components of the impact crushing station, that is, the power assembly 200 is responsible for the power output of the whole machine.

[0043] The feed hopper 10 is arranged on the frame assembly 100 , specifically located at the rear of the frame assembly 100 , and is used for material entry, that is, material to be crushed (crushed product), such as building concrete, etc., enters through the feed hopper 10 .

[0044] The vibration motor 20 is installed on the feeding hopper 10 to drive the material in the feeding hopper 10 out of the feeding hopper 10 through vibration. The bottom of the feeding hopper 10 has a slightly inclined slope, and the side opening toward the front end is set. Through the vibration of the vibration motor 20, the material can be driven out of the feeding hopper 10 and conveyed to the crushing mechanism 30 through the conveyor belt for crushing. The vibration motor 20 is set at the bottom of the feeding hopper 10. The amplitude of the feeding hopper 10 is adjusted by controlling the speed of the vibration motor 20. The greater the speed, the greater the amplitude, the faster the feeding speed, and the smaller the amplitude, the smaller the feeding speed, so that the speed of the material in the feeding hopper 10 coming out of the feeding hopper 10 can be controlled by controlling the vibration of the vibration motor 20.

[0045] The crushing mechanism 30 is arranged on the frame assembly 100 and is used to crush the materials coming out of the feed hopper 10. The crushing mechanism 30 has a crushing main machine and can crush large materials into small materials. When crushing materials such as building concrete, ferromagnetic impurities such as steel bars are generated.

[0046] The main conveyor belt 40 is arranged on the frame assembly 100 and is used to convey the materials crushed by the crushing mechanism 30. The large materials crushed by the crushing mechanism 30 become small materials mixed with ferromagnetic impurities such as steel bars, and fall onto the main conveyor belt 40 and are conveyed by the main conveyor belt 40.

[0047] The iron remover 50 is mounted on the frame assembly 100 and is used to absorb ferromagnetic impurities in the material transported by the main conveyor belt 40. The iron remover 50 is located at the upper middle portion of the main conveyor belt 40 and preferably adopts an electromagnetic form. When the iron remover 50 is turned on, it can absorb ferromagnetic impurities such as steel bars mixed in the small materials transported by the main conveyor belt 40 to achieve material iron removal.

[0048] An angle sensor 60 is provided above the main conveyor belt 40. The angle sensor 60 is fixedly mounted on the frame assembly 100. The angle sensor 60 is provided with a baffle 61 facing the main conveyor belt 40 and capable of detecting the angle of the baffle 61. The baffle 61 has a rotating shaft, which is installed in the hole of the angle sensor 60 and can rotate. The baffle 61 can be set to a 0° position when in a natural state, and can rotate around the rotating shaft when driven by an external object so that the angle sensor 60 can detect the rotation angle of the baffle 61.

[0049] The control system includes a control chip, which is an ECU or a PLC and is equipped with a frequency converter. The control system is electrically connected to the angle sensor 60 and the vibration motor 20. The angle sensor 60 transmits the angle signal of the baffle 61 to the control system, and the control system controls the vibration motor 20 according to the angle signal to control the discharge speed of the feed hopper 10.

[0050] During implementation, large materials enter through the feeding hopper 10. Under the action of the vibration motor 20, the feeding hopper 10 feeds at a certain speed. The crushing mechanism 30 crushes the large materials to form small materials and conveys them through the main conveyor belt 40. When there are too many impurities such as steel bars on the main conveyor belt 40, the raised steel bars will contact the baffle 61 when passing through the baffle 61 and cause the baffle 61 to rotate, which is then detected by the angle sensor 60. The angle sensor 60 transmits a signal to the control system, and the control system controls the frequency converter, thereby controlling the speed of the vibration motor 20 under the feeding hopper 10 to adjust the feeding speed of the feeding hopper 10. Specifically, the vibration motor 20 is controlled to reduce the rotation speed, thereby reducing the amplitude of the vibration motor 20 to reduce the feeding speed of the feed hopper 10, that is, to realize automatic adjustment of material transmission. By reducing the feeding speed, the impurities such as steel bars on the main conveyor belt 40 can be reduced accordingly to ensure the iron removal effect of the iron remover 50, and avoid or reduce excessive protruding impurities such as steel bars hitting the iron remover 50 and damaging the iron remover 50, thereby extending the life of the iron remover 50; at the same time, the baffle 61 can also flatten some protruding impurities such as steel bars to prevent the protruding impurities such as steel bars from directly hitting the iron remover 50 and damaging the iron remover 50, thereby extending the life of the iron remover 50.

[0051] The automatic adjustment system for material transmission of the impact crusher of the present invention can monitor through the angle sensor 60 when there are too many impurities such as steel bars, and then control the rotation speed of the vibration motor 20 under the feeding hopper 10 through the control system to reduce the feeding speed of the feeding hopper 10, so as to realize automatic adjustment of material transmission, and reduce the impurities such as steel bars on the main conveyor belt 40 accordingly by reducing the feeding speed, so as to ensure the iron removal effect of the iron remover 50, and avoid or reduce excessive protruding impurities such as steel bars hitting the iron remover 50 and damaging the iron remover 50. At the same time, some protruding impurities such as steel bars are scraped flat by the baffle plate 61 to avoid the protruding impurities such as steel bars directly hitting the iron remover 50 and damaging the iron remover 50, thereby extending the life of the iron remover 50.

[0052] In a preferred embodiment, the baffle 61 is located in front of the iron remover 50 and is tilted toward the iron remover 50. That is, in a natural state, the baffle 61 is tilted toward the iron remover 50, so that the baffle 61 can rotate and flatten the raised steel bars and other impurities when it comes into contact with them.

[0053] Preferably, the impact crusher material transmission automatic adjustment system also includes an audible and visual alarm, which is electrically connected to the control system, so that when the baffle 61 rotates and is detected by the angle sensor 60, the control system follows up the detected angle signal to control the audible and visual alarm to alarm, realizes an alarm output, and reminds the on-site staff. In an exemplary embodiment, the alarm of the audible and visual alarm can be that as long as the baffle 61 rotates and is detected by the angle sensor 60 and transmits the signal to the control system, the control system controls the audible and visual alarm to alarm, or the baffle 61 rotates continuously for a certain period of time or rotates multiple times within a certain period of time and is detected by the angle sensor 60 and transmits the signal to the control system, and the control system controls the audible and visual alarm to alarm.

[0054] like Figures 3 to 5 As shown, in a preferred embodiment, the iron remover 50 includes a bracket 51, a support rod 52, a drive cylinder 53, a first hanging bar 54, a second hanging bar 55 and an iron remover body 56.

[0055] The bracket 51 serves as the supporting structure of the entire iron remover 50. In this preferred embodiment, the bracket 51 includes two bracket units arranged opposite to each other. The two bracket units have the same structure. The bracket units arranged opposite to each other include bracket legs 511 located at both ends, and a bracket beam 512 is arranged between the bracket legs 511 located at both ends. The bracket legs 511 are fixedly mounted on the frame assembly 100 and are located above the main conveyor belt 40. The bracket legs 511 located at both ends may have different heights and different inclination angles. For example, in this preferred exemplary embodiment, the bracket leg 511 located at one end is short and has a small inclination, and the bracket leg 511 located at the other end is long and has a large inclination. At this time, a bracket beam 512 is arranged between the bracket legs 511 located at both ends and is arranged in an inclined manner. Preferably, the bracket legs 511 and the bracket beam 512 are integrally stamped and formed. In other preferred embodiments, the bracket legs 511 and the bracket beam 512 may also be fixed by welding or the like. A cross bar 513 is arranged between the bracket legs 511 of the two bracket units. The cross bar 513 can enhance the structural stability of the bracket 51. The cross bar 513 can be a round bar structure or an I-beam structure. It can be fixedly installed on the bracket leg 511 by welding or the like, or it can be detachably installed on the bracket leg 511 by bolt connection or the like.

[0056] There are two support rods 52, which are transversely arranged on the bracket 51, and specifically, the two ends are installed on the bracket beam 512 by bolts, and the two support rods 52 are transversely arranged and parallel to each other. In this exemplary embodiment, since the bracket beam 512 is inclined, the two support rods 52 are at different heights, and specifically, the support rod 52 away from the driving cylinder 53 is higher.

[0057] There are two drive cylinders 53 to realize the dual-cylinder drive form, and the two drive cylinders 53 operate simultaneously. The drive cylinder 53 extends longitudinally, and the end of the drive cylinder 53 is rotatably connected to the bracket 51, specifically, the end of the drive cylinder 53 is rotatably mounted on the crossbar 513, and the rotation direction is upward or downward rotation around the rotation point. The drive cylinder 53 preferably adopts one of an oil cylinder, an air cylinder or an electric cylinder. In this exemplary embodiment, the drive cylinder 53 uses a hydraulic cylinder and adopts a dual hydraulic cylinder drive control form. By adopting a hydraulic system, precise control, fuel saving and environmental protection are achieved, and the control method is realized by a hydraulic cylinder operating valve, that is, the hydraulic cylinder can be operated to achieve lifting and lowering, and the operation is flexible and convenient. At the same time, the maintenance of the hydraulic cylinder is more convenient, and it no longer costs manpower to adjust the height of the iron remover body 56 on the machine. The drive cylinder 53 is electrically connected to the control system so that it can be controlled by the control system to shrink.

[0058] The first suspension bar 54 and the second suspension bar 55 are chains or ropes, or other flexible pulling objects. The first suspension bar 54 and the second suspension bar 55 should have a certain strength to bear the weight of the iron remover body 56 without breaking to avoid the iron remover body 56 falling. In this preferred embodiment, the first suspension bar 54 and the second suspension bar 55 are O-shaped chains.

[0059] One end of the first suspension bar 54 goes around a support rod 52 away from the drive cylinder 53 and then goes down, and the other end goes around another support rod 52 close to the drive cylinder 53 and then goes down, and the middle part of the first suspension bar 54 is connected to the front end of one of the drive cylinders 53. For example, in an exemplary embodiment, the end (main body) of one of the drive cylinders 53 of the hydraulic oil cylinder is rotatably connected to the bracket 51, and the front end (telescopic rod) is connected to the middle part of the first suspension bar 54. It should be understood that in the present invention, the middle part connection of the first suspension bar 54 is not limited to the middlemost part of the first suspension bar 54 or the part close to the middlemost part, and the middle part of the first suspension bar 54 can be other parts except the two ends.

[0060] One end of the second suspension bar 55 goes around a support rod 52 away from the drive cylinder 53 and then goes down, and the other end goes around another support rod 52 close to the drive cylinder 53 and then goes down, and the middle of the second suspension bar 55 is connected to the front end of one of the drive cylinders 53. For example, in an exemplary embodiment, the end (main body) of one of the drive cylinders 53 of the hydraulic oil cylinder is rotatably connected to the bracket 51, and the front end (telescopic rod) is connected to the middle of the second suspension bar 55. It should be understood that in the present invention, the middle connection of the second suspension bar 55 is not limited to the middlemost part of the first suspension bar 54 or the part close to the middlemost part, and the middle of the second suspension bar 55 can be other parts except the two ends.

[0061] In the utility model, the first suspension bar 54 is connected to a driving cylinder 53, and the second suspension bar 55 is connected to a driving cylinder 53. The first suspension bar 54 and the second suspension bar 55 are controlled by double-cylinder driving to realize a double-cylinder driven lifting iron remover 50.

[0062] The iron remover body 56 removes ferromagnetic impurities such as steel bars mixed in the material by generating a strong magnetic field attraction. The iron remover body 56 is connected to the two ends of the first suspension bar 54 and the second suspension bar 55, and is suspended at a certain position and height by the pulling of the first suspension bar 54 and the second suspension bar 55. In this exemplary embodiment, the iron remover body 56 is a rectangular parallelepiped structure as a whole, and is arranged horizontally as a whole. The first suspension bar 54 and the second suspension bar 55 have four ends in total, and are respectively connected to the two sides of the two ends of the iron remover body 56.

[0063] During implementation, the iron remover body 56 is suspended at a certain position and height by the pulling of the first hanging bar 54 and the second hanging bar 55, and is a certain distance away from the main conveyor belt 40. When there are too many impurities such as steel bars on the main conveyor belt 40, the control system can control the drive cylinder 53 to retract, pull the two ends of the first hanging bar 54 and the second hanging bar 55 upward, and the iron remover body 56 rises accordingly. At this time, the height of the iron remover body 56 can be raised, avoiding or reducing the impact of too many protruding impurities such as steel bars on the iron remover 50 and damaging the iron remover body 56, thereby extending the life of the iron remover 50. Correspondingly, when the drive cylinder 53 is extended, it drives the two ends of the first hanging bar 54 and the second hanging bar 55 downward, and the iron remover body 56 drops accordingly.

[0064] The main conveyor belt 40 is arranged at an inclination. Based on this, on the one hand, the height of the connection point with the iron remover body 56 can be adjusted by adjusting the length of the end of the first hanging bar 54 and the second hanging bar 55 connecting the iron remover body 56, so as to adjust the iron remover body 56 to be inclined to a certain angle, so that the bottom of the iron remover body 56 is arranged parallel to the main conveyor belt 40. On the other hand, the iron remover body 56 can also be adjusted to be inclined to a certain angle by adjusting the position where the drive cylinder 53 is connected to the middle part of the first hanging bar 54 and the second hanging bar 55, so that the bottom of the iron remover body 56 is arranged parallel to the main conveyor belt 40.

[0065] The front end of the driving cylinder 53 is provided with a hanging ring 531, and the first hanging bar 54 and the second hanging bar 55 pass through the hanging ring 531 respectively. During implementation, the front ends of the two driving cylinders 53 are respectively provided with a hanging ring 531, the first hanging bar 54 passes through the hanging ring 531 at the front end of the driving cylinder 53 on the same side, and the second hanging bar 55 passes through the hanging ring 531 at the front end of the driving cylinder 53 on the same side. At this time, the first hanging bar 54 and the second hanging bar 55 can move in the hanging ring 531, so that by adjusting the position of the first hanging bar 54 and the second hanging bar 55 acting on the hanging ring 531, the first hanging bar 54 and the second hanging bar 55 are adjusted to use the position where the hanging ring 531 contacts as a dividing line, and the length of the hanging bars on both sides, so as to adjust the inclination angle of the iron remover body 56. The first hanging bar 54 and the second hanging bar 55 pass through the hanging ring 531 respectively, and the two end parts are respectively bypassed around the support rod.

[0066] The first hanging bar 54 and the second hanging bar 55 of the chain are inserted with a limit pin 541 at the part passing through the hanging ring 531, and the limit pin 541 is located below the hanging ring 531. In other preferred embodiments, the limit pin 541 can also be located below the hanging ring 531 and set below the hanging ring 531 at the same time. The iron remover body 56 has a certain weight. Under the pull of the first hanging bar 54 and the second hanging bar 55, it can generally keep the angle unchanged under its own weight and the action of the hanging ring 531 and the first hanging bar 54 and the second hanging bar 55. However, sometimes when the iron remover 50 and its supporting device move, causing the iron remover 50 to shake or the iron remover body 56 of the iron remover 50 to contact the outside, the angle of the iron remover body 56 may change. At this time, by inserting the limit pin 541 into the part of the first hanging bar 54 and the second hanging bar 55 passing through the hanging ring 531, the limit pin 541 cannot pass through the hanging ring 531, and the first hanging bar 54 and the second hanging bar 55 can be limited to not move in the hanging ring 531, thereby maintaining the angle of the iron remover body 56. When the angle of the iron remover body 56 needs to be adjusted, the first hanging bar 54 and the second hanging bar 55 can be adjusted by removing the limit pin 541.

[0067] Preferably, a connecting seat 532 is provided on the hanging ring 531, and the connecting seat 532 is rotatably connected to the front end of the driving cylinder 53. By providing the connecting seat 532 and the rotatably connected relationship, the pulling on the end of the driving cylinder 53 can be better adapted to during the extension and retraction process of the driving cylinder 53.

[0068] The first suspension bar 54 and the second suspension bar 55 are hung on the support rod 52. When the iron remover body 56 is lifted or moved, the first suspension bar 54 and the second suspension bar 55 may axially deflect on the support rod 52, affecting the normal use of the iron remover body 56. In a preferred embodiment, two turntables 521 are installed on each support rod 52, and the turntable 521 is coaxially rotatably installed on the support rod 52. The turntable 521 can only rotate on the support rod 52 but cannot move axially. The first suspension bar 54 and the second suspension bar 55 bypass the turntable 521. Then, by setting the turntable 521, it can be ensured that the first suspension bar 54 and the second suspension bar 55 can only be pulled at one position on the support rod 52 without axial deviation. At the same time, the setting of the turntable 521 can also reduce the friction between the first suspension bar 54 and the second suspension bar 55 and the support rod 52, that is, the sliding friction between the first suspension bar 54 and the second suspension bar 55 and the support rod 52 is converted into the rolling friction between the support rod 52 and the turntable 521, so that the first suspension bar 54 and the second suspension bar 55 can be pulled more smoothly, and the first suspension bar 54 and the second suspension bar 55 can also be protected to avoid damage and breakage that affect use. The turntable 521 is installed at both ends of the support rod 52, and is located directly above the connection point between the ends of the first suspension bar 54 and the second suspension bar 55 and the iron remover body 56, so that the iron remover body 56 can be lifted and lowered more smoothly.

[0069] The above is only a specific implementation of the utility model, but the protection scope of the utility model is not limited thereto. Any changes or substitutions that can be easily thought of by a person skilled in the art within the technical scope disclosed by the utility model should be included in the protection scope of the utility model. Therefore, the protection scope of the utility model should be based on the protection scope of the claims.
