DETAILED DESCRIPTION
[0018] The technical solution of this patent is further described in detail below in conjunction with specific implementation methods.
[0019] like Figure 1-3As shown, the utility model provides a technical solution: a grinding device for limestone production, comprising a grinding mill 1, a discharge pipe 4 is arranged on the grinding mill 1, one end of the discharge pipe 4 is connected to a box body 5, a box door 6 is hinged on the box body 5, and a first handle 7 is fixedly connected to one side of the box door 6. Because the first handle 7 is provided, when the first handle 7 is pulled to open the box door 6, the first handle 7 makes the box door 6 easier to be opened, thereby improving the convenience of operation.
[0020] A fixed plate 13 is fixedly connected inside the box body 5, and a movable rod 12 is slidably connected to the fixed plate 13. A sieve plate 10 is fixedly connected to one end of the movable rod 12. Two guide rods 11 are fixedly connected to the top of the sieve plate 10. Because the guide rods 11 are provided, the guide rods 11 can guide the limestone blocks flowing down the sieve plate 10, so that the limestone blocks are more concentrated and convenient for collection. A baffle 21 is fixedly connected to the movable rod 12.
