Description

Technical Field

[0001] The utility model relates to the field of stone crushers, in particular to a stone crusher for preventing blockage in mines. Background Art

[0002] A stone crusher, also known as a crusher, is a comminution machine used in the processing of metal and non-metallic ores. It breaks raw ore into small particles through squeezing and bending. It is widely used in a wide range of sectors, including mining, smelting, building materials, highways, railways, water conservancy, and the chemical industry. It is primarily used for coarse, medium, and fine crushing of various materials with a compressive strength of no more than 320 MPa.

[0003] When the existing crusher is crushing mine ores, if the material is not dropped in time at the feed port, it is easy to get blocked. When the feed port of the crusher is blocked, if it is not discovered and handled in time, the subsequent ore continues to be put into the crusher, which will make the blockage more and more serious, thereby affecting the normal progress of the crushing work. Moreover, when the crusher is blocked, it needs to be cleared manually with tools, which is extremely inconvenient, time-consuming and labor-intensive to operate. Utility Model Content

[0018] In order to make the technical means, creative features, objectives and effects achieved by the present invention easier to understand, the present invention is further described below in conjunction with specific implementation methods.

[0019] like Figure 1-Figure 4 As shown, a blockage-proof mine crusher includes a crusher body 1 and a driving motor 2. A transmission wheel 3 and a flywheel 4 are installed on the crusher body 1. A bottom plate 8 is provided at the lower end of the crusher body 1, and a discharge port 10 is provided at the lower end of the crusher body 1. An anti-blocking structure 9 is installed on the bottom plate 8. A movable plate 5 is installed inside the crusher body 1, and a fixed plate 6 is provided inside the crusher body 1. A vibration mechanism 7 is provided at the lower end of the crusher body 1. A transmission belt is connected between the driving motor 2 and the transmission wheel 3, and the vibration mechanism 7 is connected to the lower end of the movable plate 5.

[0020] When using the crusher to crush ore, the crusher body 1 and the drive motor 2 are installed on the support frame, the anti-blocking structure 9 is installed on the lower surface of the base plate 8, and the transmission belt is connected between the transmission wheel 3 and the drive motor 2. After the power is turned on, the crushing work starts. After starting the drive motor 2, the transmission wheel 3 moves together, cooperates with the flywheel 4 and the vibration mechanism 7 to operate, thereby driving the movable plate 5 to vibrate back and forth. After the ore is put into the crusher body 1, the movable plate 5 and the fixed plate 6 crush the ore, and the crushed fragments fall out through the discharge port 10, thus realizing the crushing of the mine ore. During the crushing process, the anti-blocking structure 9 plays the role of clearing the discharge port 10, which can effectively prevent blockage and ensure the normal progress of the crushing work.

[0021] Through the above embodiment, the anti-blocking structure 9 includes a reduction motor 901, a mounting plate 902, a cam 904, a movable rod 905, a linear rack 908 and a dredging component 909. The reduction motor 901 and the mounting plate 902 are mounted on the base plate 8, the cam 904 is arranged on the mounting plate 902, the movable rod 905 is connected to the mounting plate 902, and the end of the movable rod 905 is fixedly connected to the linear rack 908, the dredging component 909 is mounted on the base plate 8, and the dredging component 909 is connected to the movable rod 905. The anti-blocking structure 9 also includes a mounting frame 903, Roller 906, return spring 907, guide rod 910 and motor seat 911, mounting frame 903 is connected to mounting plate 902, and the upper end of mounting frame 903 is fixed to bottom plate 8, roller 906 is arranged at the end of movable rod 905, and roller 906 and cam 904 are abutted together, return spring 907 is sleeved on movable rod 905, guide rod 910 is mounted on mounting plate 902, and guide rod 910 is slidably connected with linear rack 908, motor seat 911 is connected to bottom plate 8, reduction motor 901 is fixed on motor seat 911, dredge Component 909 includes a bracket 9091, a connecting plate 9092, a slide 9093, an arcuate guide rail 9094, an arcuate rack 9095 and a knock rod 9096. The bracket 9091 is fixed to the bottom plate 8 through the connecting plate 9092. The slide 9093 is connected to the lower end of the bracket 9091. The arcuate guide rail 9094 is fixedly connected to the arcuate rack 9095, and the arcuate guide rail 9094 is slidably connected to the slide 9093. The knock rod 9096 is arranged at the end of the arcuate rack 9095. The anti-blocking structure 9 is provided, which can play a role in the process of ore crushing. In order to achieve the effect of dredging and anti-blocking, the reduction motor 901 is used to drive the cam 904 to rotate, and is used in conjunction with the roller 906 and the return spring 907, so that the movable rod 905 reciprocates on the mounting plate 902, thereby driving the arc rack 9095 to perform reciprocating circular motion through the linear rack 908, and the knocking rod 9096 moves back and forth at the discharge port 10, and can intermittently knock the crushed materials at the discharge port 10, thereby ensuring the dredging effect. The linear rack 908 and the arc rack 9095 are meshedly connected to ensure transmission accuracy and stability.

[0022] When installing the anti-blocking structure 9, use the mounting bracket 903 to install the mounting plate 902, and use the motor seat 911 to install the reduction motor 901. At the same time, ensure that the reduction motor 901 is connected to the cam 904. The bracket 9091 in the dredging component 909 is fixed to the bottom plate 8 through the connecting plate 9092. The slide seat 9093 at the lower end of the bracket 9091 is connected to the arc guide rail 9094 on the Zeyu arc rack 9095. During the installation process, ensure that the linear rack 908 is meshed with the arc rack 9095. When the anti-blocking structure 9 is installed and used, start the reduction motor 901 during use, and the cam 904 rotates. During this process, the roller 906 contacts the cam 904 and rotates together, while exerting a force on the movable rod 905, and cooperating with the reset spring 907, so that the movable rod 905 reciprocates on the mounting plate 902, thereby carrying the linear rack 908 to reciprocate on the guide rod 910. Since the linear rack 908 is meshed and connected with the arc rack 9095, the arc rack 9095 will perform reciprocating circular motion on the slide 9093 through the arc guide rail 9094, so that the knocking rod 9096 reciprocates in and out of the discharge port 10, thereby playing a role in clearing and preventing blockage, and avoiding blockage at the discharge port 10.
