DETAILED DESCRIPTION
[0017] The following is combined with Figure 1 This application is described in further detail.
[0018] The embodiment of the present application discloses a tunnel slag crushing device.
[0019] Reference Figure 1The tunnel slag crushing device includes a crusher body and an auxiliary mechanism 12 for assisting in stone crushing. The auxiliary mechanism 12 is respectively arranged on both sides of the feed port of the crusher body and the distribution direction is perpendicular to the feed direction. The auxiliary mechanism 12 includes a base 11 located on the side of the crusher feed port and an impact hammer 121 and a power assembly 13 arranged on the base 11. The power assembly 13 is connected to the impact hammer 121. Through the power assembly 13, the impact hammer 121 can be pushed toward the feed port of the crusher body to impact and crush the gravel.
[0020] Reference Figure 1 The impact direction of the impact hammer 121 is perpendicular to the feeding direction of the crushed stone, and the end face of the impact hammer 121 facing the crusher feed port is provided with a long strip of tooth structure, which can increase the pressure of the force point and is more conducive to crushing the slag and crushed stone.
[0021] Reference Figure 1 The power assembly 13 is connected to the side of the impact hammer 121 away from the crusher feed port. The power assembly 13 includes a limit assembly 14, a driving block 131, a connecting rod 132, a connecting rod 2 133 and a motor 134 located on the base 11.
[0022] Reference Figure 1 The limiting assembly 14 includes a fixing block 142 fixedly connected to the base 11 and a limiting rod 141 passing through the fixing block 142. One end of the limiting rod 141 is connected to the impact hammer 121, and the other end is detachably connected to the driving block 131 through bolts and nuts. The limiting rod 141 passing through the fixing block 142 is conducive to constraining the limiting rod 141 and the driving block 131 to move in a straight line, thereby pushing the impact hammer 121 to impact the gravel along a straight line trajectory.
[0023] Reference Figure 1 The end of the driving block 131 facing away from the impact hammer 121 is hinged to the second connecting rod 133, and the other end of the second connecting rod 133 is hinged to the first connecting rod 132. The other end of the first connecting rod 132 is fixed to the output shaft of the motor 134. The output shaft of the motor 134 extends out of the edge of the base 11, so that when the motor 134 drives the first connecting rod 132 to rotate, the base 11 will not interfere with the movement of the connecting rod. The length of the first connecting rod 132 is less than the length of the second connecting rod 133. The motor 134 drives the first connecting rod 132 to rotate, so that the angle and position of the second connecting rod 133 change, and further promotes the displacement of the driving block 131, so as to achieve the effect of making the impact hammer 121 impact toward the feed port of the crusher.
[0024] Reference Figure 1, a protective cover 15 in the shape of an arc for blocking the splashing of crushed stones is fixedly connected to the crusher body. One end of the protective cover 15 is connected to the side of the feeding port of the crusher body away from the feeding end, and the other end covers the upper part of the feeding port of the crusher body. A sponge pad is provided on the side of the protective cover 15 facing the feeding port of the crusher body. The sponge pad is detachable and can be fixed by non-stick glue. The sponge pad can partially isolate the direct impact of crushed stones on the protective cover 15, which is beneficial to reducing the noise generated by collisions during use.
[0025] Refer to Figure 1 , on the upper end of the side of the two bases 11 close to the feeding port of the crusher, a sand baffle 16 is detachably connected by bolts and nuts. Windows for the impact hammers to pass through are provided on the sand baffle 16. The sand baffle 16 can effectively block the crushed stones from splashing onto the tabletop of the base 11 and affecting the displacement of the impact hammers 121.
[0026] Refer to Figure 1 , a distance measuring sensor 17 for detecting the distance between the sand baffle and the crushed stones is embedded in the sand baffle 16 and faces the feeding port. Bases 1 are respectively arranged on both sides of the crusher body, and the base 11 is placed on the base 1. A slider extends outward from the bottom of the base 11, and a chute is provided on the upper surface of the base. The slider is slidably connected to the chute so that the base 11 is slidably connected to the base 1; the sliding direction of the base 11 is the same as the moving direction of the impact hammers 121. A servo hydraulic cylinder 18 is installed on the side of the base 1 away from the crusher body. The cylinder body of the servo hydraulic cylinder 18 is fixed to the base 1 and the telescopic rod end is fixedly connected to the base 11; a controller is provided. The controller can be a PLC control cabinet, and the servo hydraulic cylinder 18, the distance measuring sensor 17, and the motor 134 are respectively electrically connected to the controller.
[0027] Embodiment
[0028] First, power on the device and let the crusher body work, and then deliver the stones to be crushed to the feeding port of the crusher body through the conveyor belt; during the process:
[0029] Manual mode. If the staff finds that there are large stones stuck in the feeding port, control the motor 134 to work, so as to drive the impact hammers 121 to impact the large stones through the crank transmission structure, and impact simultaneously from left and right to break the large stones into small stones and relieve the problem of material jamming;
[0030] Semi-automatic mode: The controller presets a standard distance range. If the distance detection value feedback by the distance measuring sensor 17 falls within the standard distance range, the motor 134 is controlled to rotate with the preset control parameters, so that the impact hammer 21 repeatedly impacts the stone. After the rotation stops, the impact hammer 121 is dragged out of the sand guard plate 16 to avoid interfering with normal feeding. If the distance detection value feedback by the distance measuring sensor 17 exceeds the standard distance range and exceeds a, first control the servo hydraulic cylinder 18 to extend by a, and then control the motor 134 to rotate with the preset control parameters, so that the impact hammer 21 repeatedly impacts the stone. After the rotation stops, the impact hammer 121 is dragged out of the sand guard plate 16 to avoid interfering with normal feeding.
[0031] The above are all preferred embodiments of the present application, and the protection scope of the present application is not limited thereby. Therefore, all equivalent changes made according to the structure, shape, and principle of the present application should be covered within the protection scope of the present application.
