[0032] Figures 1 to 9 is a schematic view of some embodiments of a crusher that is easy to maintain.

[0033] Referring to Figures 1 to 9 , and mainly referring to Figure 1 , Figure 2 , Figure 3 , Figure 5 , Figure 6 and Figure 9 , a crusher that is easy to maintain according to some embodiments of the present application, for the convenience of description, is sometimes referred to as "crusher" hereinafter. A crusher that is easy to maintain includes a crusher main body 100, a pusher assembly 200 and a detection device 300. The crusher main body 100 is internally provided with a crushing cavity 110, and a crushing shaft 130 is rotatably installed inside the crushing cavity 110. In this embodiment, the crusher main body 100 is roughly in the shape of a cuboid. A support 101 is detachably installed at the lower part of the crusher main body 100. The support 101 supports and holds the crusher main body 100, so that there is a certain distance between the lower part of the crusher main body 100 and the ground or supporting surface. A discharge port 102 is formed at the bottom of the crusher main body 100 and is in communication with the crushing cavity 110. Therefore, the enterprise can place a receiving tray in the middle of the support 101. At this time, the receiving tray is located below the discharge port 102, and the tray can receive solid waste that has been crushed by the crushing shaft 130.

[0034] The pusher assembly 200 comprises a pusher body 210, two sets of connecting mechanisms 220 and two sets of driving mechanisms 230. The pusher body 210 is movably installed inside the crushing cavity 110. The two sets of connecting mechanisms 220 are arranged at two ends of the pusher body 210 in one-to-one correspondence. The pusher body 210 is movably connected to the two opposite side walls of the crusher body 100 through the two sets of connecting mechanisms 220. The two sets of driving mechanisms 230 are arranged at the top of the two opposite side walls of the crusher body 100 in one-to-one correspondence. The two sets of driving mechanisms 230 are in transmission connection with the two sets of connecting mechanisms 220 in one-to-one correspondence. Specifically, one set of driving mechanisms 230 is in transmission connection with one set of connecting mechanisms 220, and the other set of driving mechanisms 230 is in transmission connection with the other set of connecting mechanisms 220. The two sets of driving mechanisms 230 can drive the pusher body 210 to swing towards or away from the crushing shaft 130 through the two sets of connecting mechanisms 220. The detection device 300 is arranged at the top of the side wall of the crusher body 100 and located at one side of the connecting mechanism 220. The detection device 300 is used to detect the swinging condition of the connecting mechanism 220. The detection device 300 is provided with an indicating device for feeding back the detection result.

[0035] The crusher of the present embodiment is provided with the detection device 300 at the top of the side wall of the crusher body 100. The detection device 300 is located at one side of the connecting mechanism 220. The detection device 300 is used to detect the swinging condition of the connecting mechanism 220. The detection device 300 is provided with an indicating device for feeding back the detection result. Therefore, when the crusher of the present embodiment is started and crushing solid waste, a worker standing at one side of the crusher can watch the detection device 300 at the top of the side wall of the crusher body 100. The worker can judge whether the pusher body 210 inside the crushing cavity 110 normally moves the solid waste to approach the crushing shaft 130 by watching the indicating device of the detection device 300. The worker does not need to stand on a stool or climb a ladder to watch the running condition of the pusher body 210 inside the crushing cavity 110. This greatly facilitates the worker to overhaul and maintain the crusher. In addition, when the crusher is assembled and tested, the worker standing at one side of the crusher can judge the running condition of the pusher body 210 of the crusher by watching the indicating device of the detection device 300. This greatly facilitates the worker to install and debug the crusher.

[0036] Referring to Figure 2 , Figure 3 , Figure 4 , Figure 5 , Figure 6 , Figure 7 , Figure 8 and Figure 9, in order to facilitate the pusher assembly 200 better installed in the crusher body 100, in some embodiments of the present application, the crusher body 100 corresponding position relative to the two side wall top are provided with installation groove 120, each set of connecting mechanism 220 includes base 221, rotating shaft 222, first swing rod 223 and second swing rod 224, rotating shaft 222 is rotatably mounted on the base 221, one end of the first swing rod 223 is connected with the rotating shaft 222, the other end of the first swing rod 223 is connected with the pusher body 210, one end of the second swing rod 224 is connected with the rotating shaft 222, two base 221 of two sets of connecting mechanism 220 are detachably installed in the two installation groove 120, two sets of driving mechanism 230 are in one-to-one correspondence with the other end of the two second swing rod 224 transmission connection. When the driving mechanism 230 drives the second swing rod 224 to swing, the second swing rod 224 drives the first swing rod 223 to swing through the rotating shaft 222, the first swing rod 223 drives the pusher body 210 to swing around the rotating shaft 222, and then the pusher body 210 pushes the solid waste to move close to the crushing shaft 130.

[0037] By adopting the above structure, when the workers assemble the crusher, the workers can first assemble two sets of connecting mechanism 220 and pusher body 210 to form an integral workpiece, then the workers move the pusher body 210 and two sets of connecting mechanism 220 along the direction from top to bottom and embed them inside the crushing cavity 110, and make two base 221 of two sets of connecting mechanism 220 correspondingly embedded in two installation groove 120, then lock two base 221 in the corresponding installation groove 120, that is, complete the assembly of two sets of connecting mechanism 220 and the crusher body 100, then connect two sets of driving mechanism 230 with two sets of connecting mechanism 220 two second swing rod 224 in one-to-one correspondence transmission connection, the assembly is more simple and fast, and the enterprise also does not need to process two coaxial rotating holes in the two opposite side walls of the crushing cavity 110, so that the machining precision of the crusher body 100 can be greatly reduced, the machining difficulty is reduced, and the production efficiency of the enterprise is improved.

[0038] Referring to Figure 1 , Figure 2 , Figure 3 and Figure 9In order to make the detection device 300 better detect the swing condition of the connecting mechanism 220, in some embodiments of the present application, the detection device 300 comprises a mounting frame 310 and two or more detection sensors 320, the mounting frame 310 is arranged on the side wall of the crusher main body 100, and the mounting frame 310 is located on one side of the second swing rod 224 of one set of connecting mechanisms 220, the mounting frame 310 is provided with at least two mounting holes 311, one detection sensor 320 is arranged in one of the mounting holes 311, and another detection sensor 320 is arranged in the other mounting hole 311, and each detection sensor 320 is provided with an indicating device at an end away from the second swing rod 224, and the indicating device is an indicating lamp. In this embodiment, the detection sensor 320 described above is a proximity sensor or an infrared sensor. By adopting the above structure, when the driving mechanism 230 drives the second swing rod 224 to swing, the second swing rod 224 swings around the rotating shaft 222, the detection sensor 320 detects the second swing rod 224, and the indicating lamp at the end of the detection sensor 320 away from the second swing rod 224 emits light, the worker stands on one side of the crusher and observes the light-emitting condition of the detection sensor 320, and it can be determined whether the swing condition of the second swing rod 224 meets the predetermined condition, so as to determine whether the material pushing device body 210 normally pushes the material, so that the worker does not need to stand on a stool or climb a ladder to observe whether the material pushing device body 210 normally pushes the material, greatly facilitating the worker to maintain and repair the crusher.

[0039] Further, the number of detection devices 300 is two sets, and the two sets of detection devices 300 are arranged one by one on the top of the opposite two side walls of the crusher main body 100. By arranging one set of detection devices 300 on the top of the opposite two side walls of the crusher main body 100 respectively, the worker can avoid the situation that the detection result is inaccurate due to the failure of one set of detection devices 300, thereby improving the detection accuracy of the crusher in this embodiment.

[0040] In some embodiments of the present application, the mounting frame 310 is in the shape of a circular arc, the number of mounting holes 311 is three, the three mounting holes 311 are arranged in sequence and uniformly spaced along the mounting frame 310, and the number of detection sensors 320 is three, and the three detection sensors 320 are arranged one by one in the three mounting holes 311. The three detection sensors 320 described above correspond to the start position, the middle position and the end position in the swing process of the second swing rod 224 in sequence. When the crusher in this embodiment is normally started, the worker can judge whether the swing condition of the second swing rod 224 meets the expectation by observing whether the three detection sensors 320 emit light in sequence, so as to facilitate the user to maintain or adjust the crusher.

[0041] Further, the mounting hole 311 is a strip-shaped hole, the detection sensor 320 is movably mounted in the mounting hole 311, the detection sensor 320 is provided with a locking structure capable of clamping or releasing the mounting rack 310, in the embodiment, the locking structure is a nut mounted on the outer periphery of the detection sensor 320, by adopting the above structure, when the worker movably mounts the detection sensor 320 in the mounting hole 311, and adjusts the position of the detection sensor 320, the user tightens the nut to press and clamp the mounting rack 310, so as to realize the purpose of fine adjustment of the mounting of the detection sensor 320 on the mounting rack 310, which is convenient for the worker to adjust the position of the detection sensor 320.

[0042] In some embodiments of the present application, the crusher also controls the system, and the control system is electrically connected with all the detection sensors 320 and all the driving mechanisms 230. All the detection sensors 320 can feed back the detection results to the control system, and the control system can control the driving mechanism 230 to drive the second swing rod 224 to swing, or the control system can control the driving mechanism 230 to stop driving the second swing rod 224 to swing, or the control system can control the driving mechanism 230 to drive the second swing rod 224 to swing in the opposite direction. Since the number of detection sensors 320 in the embodiment is three, when the solid waste in the crushing cavity 110 is not much, the worker can set the detection sensors 320 at the middle position and the detection sensors 320 at the outermost position to detect the swinging of the second swing rod 224 by the control system, at this time, when the detection sensor 320 at the outermost position detects the second swing rod 224 and feeds back the signal to the control system, the driving mechanism 230 drives the second swing rod 224 to swing, and when the detection sensor 320 at the middle position detects the second swing rod 224 and feeds back the signal to the control system, the driving mechanism 230 drives the second swing rod 224 to swing in the opposite direction. By adopting the above structure, when the solid waste in the crushing cavity 110 is not much, the control system can adjust to shorten the swinging stroke of the second swing rod 224, so as to avoid the pusher body 210 swinging for a distance without solid waste, thereby improving the efficiency of the pusher body 210 in pushing the solid waste.

[0043] Referring to Figure 2 , Figure 5 , Figure 6 and Figure 9 , in some embodiments of the present application, the inner walls of the opposite sides of the mounting groove 120 are provided with mounting plates 121, and the two mounting plates 121 are provided with notches 122 capable of accommodating the rotating shaft 222, and the opposite sides of the base 221 are provided with connecting plates 2211, and when the base 221 is mounted in the mounting groove 120, the two connecting plates 2211 are connected with the two mounting plates 121 one by one. By adopting the above structure, when the base 221 is mounted in the mounting groove 120, the connection between the base 221 and the crusher body 100 can be more firm.

[0044] Referring to Figure 4 , Figure 5 , Figure 6 and Figure 8 , in some embodiments of the present application, the end of the first swing rod 223 connected with the pusher body 210 is provided with an inclined surface 2230 located on the side surface of the first swing rod 223 close to the inner wall of the crushing cavity 110. By adopting the above structure, the inclined surface 2230 forms a space for avoiding materials between the first swing rod 223 and the inner wall of the crushing cavity 110, so that when the pusher body 210 pushes the solid waste to move inside the crushing cavity 110, the above space can effectively prevent the solid waste from blocking the gap between the pusher body 210 and the crushing cavity 110, causing the pusher body 210 to be stuck, and thus the pusher body 210 can better push the materials to move.

[0045] Further, the driving mechanism 230 includes a hydraulic cylinder 231 and a connecting seat 232, the connecting seat 232 is installed on the top of the side wall of the crusher body 100, and the hydraulic cylinder 231 is rotatably installed on the connecting seat 232, and the piston rod of the hydraulic cylinder 231 is rotatably connected with the corresponding second swing rod 224. By adopting the above structure, the driving mechanism 230 can better push the second swing rod 224 to swing. It can be understood that, in addition to the structure composed of the above hydraulic cylinder 231 and connecting seat 232, the driving mechanism 230 can also adopt an electric push rod or an air cylinder, which can be determined according to actual needs.

[0046] Referring to Figure 1 and Figure 2 , in some embodiments of the present application, the upper part of the crushing cavity 110 is open, and the upper part of the crusher body 100 is detachably provided with a feeding cover 140, and one side of the feeding cover 140 is open. By adopting the above structure, the solid waste to be treated outside can enter the inside of the crushing cavity 110 through the opening on one side of the feeding cover 140, so that the solid waste can be better transported into the crusher for treatment.

[0047] The embodiments of the present application are described in detail above in combination with the drawings, but the present application is not limited to the above embodiments, and various changes can be made within the knowledge of those skilled in the art without departing from the purpose of the present application.
