[0028] The size of the copper bowl 4 is smaller than the diameter of the opening 3, so that the copper bowl 4 can be placed at the bottom of the chamber 2 through the opening 3;

[0029] The crushing mechanism is installed above the copper bowl 4, which includes an inner tube, a piston rod 5, an impact hammer 6 and a crushing copper hammer 7. The inner tube is vertically fixedly installed on the top of the chamber 2, the piston rod 5 is movably installed on the upper part of the inner tube, and the piston 8 at the bottom end of the piston rod 5 is sealed with the inner tube, the crushing copper hammer 7 is movably installed on the lower part of the inner tube, and the upper part of the crushing copper hammer 7 is sealed with the inner tube, and the lower part of the crushing copper hammer 7 extends outside the inner tube, the impact hammer 6 is movably installed in the middle part of the inner tube and is sealed with the inner tube, so that a sealed first cavity 9 is constructed between the impact hammer 6 and the piston 8 , and a sealed second cavity 10 is constructed between the impact hammer 6 and the crushing copper hammer 7.

The operation is simple and easy to use, and no manual hammering is required, thereby improving the detection efficiency of dolomite. At the same time, by using the copper bowl 4 and the pulverizing copper hammer 7 to pulverize the dolomite blocks, the iron content in the dolomite powder will not be increased during the pulverizing process, thereby ensuring the accuracy of the detection data.

[0032] In one preferred embodiment, the driving mechanism may include a first motor 11 and a crankshaft 12. The crankshaft 12 is rotatably installed in the inner cylinder, and one end of the crankshaft extends out of the inner cylinder and cooperates with the first motor 11 in transmission.

During the use of the pulverizing device, the first exhaust valve 19 is in a closed state, so that the piston 8 and the impact hammer 6 are in a closed state. After the pulverizing device is used, the first exhaust valve 19 can be opened to easily push the pulverizing copper hammer 7 upward, so that the pulverizing copper hammer 7 is lifted to a height higher than the copper bowl 4, so as to take the copper bowl 4 out of the chamber 2, and in the process of pushing the pulverizing copper hammer 7 upward, the impact hammer 6 gradually moves toward the piston 8, and moves until the impact hammer 6 closes the first exhaust hole 16. At this time, there is still a certain gap between the impact hammer 6 and the piston 8, and the impact hammer 6 and the piston 8 are in a closed state, so that the pulverizing copper hammer 7 cannot be easily pushed upward.

[0036] In another preferred embodiment, the pulverizing copper hammer 7 may include a connecting portion 20 that is sealed with the inner cylinder, and a hammer rod 21 arranged at the lower end of the connecting portion 20, the connecting portion 20 is in a plug shape, and the outer wall is provided with a sealing ring that is sealed with the inner cylinder, the hammer rod 21 is installed in the middle of the lower end of the connecting portion 20, the bottom end of the inner cylinder is provided with a connecting hole 22 that is matched with the hammer rod 21, a gap 23 is formed between the lower end of the connecting portion 20 and the inner cylinder, the outer wall of the inner cylinder is provided with a third exhaust hole 24 that is connected to the gap 23, the third exhaust hole 24 is provided with a second exhaust valve 25 that controls its communication diameter, and the diameter of the connecting hole 22 is matched with the diameter of the hammer rod 21. The tolerance is less than 0.15mm, so that during the movement of the copper hammer 7, the gas in the gap 23 will not be blown out from between the connecting hole 22 and the hammer rod 21, thereby preventing the blown gas from blowing the mineral powder in the copper bowl 4 out of the copper bowl 4, and the connecting diameter of the third exhaust hole 24 is adjusted by the second exhaust valve 25 to adjust the exhaust volume of the third exhaust hole 24, thereby adjusting the resistance encountered by the copper hammer 7 during the movement, and then realizing the adjustment of the hammering force of the copper hammer 7, that is, when the dolomite is just started to be hammered, a larger hammering force is required, and after a period of hammering, when the dolomite block becomes close to powder, only a smaller hammering force is required.

[0037] Preferably, the first exhaust hole 16, the second exhaust hole 18 and the third exhaust hole 24 are all connected to exhaust pipes, and the ends of the exhaust pipes can be placed in a collecting container to prevent the lubricating oil in the inner cylinder from spraying toward the operator from the first exhaust hole 16, the second exhaust hole 18 and the third exhaust hole 24.

[0038] In a more preferred embodiment, a rotating mechanism can be provided at the bottom of the chamber 2, and the copper bowl 4 can be fixedly mounted on the rotating mechanism and driven to rotate by the rotating mechanism. During the crushing process of dolomite, in order to ensure uniform crushing, the copper bowl 4 needs to be rotated during the hammering of the crushing copper hammer 7. In this embodiment, the copper bowl 4 is fixed and driven to rotate by the rotating mechanism, and the operator does not need to hold the copper bowl 4 to rotate, so as to reduce the operator's work intensity and improve the safety of operation.

The second motor 27 is fixedly installed at the bottom of the body 1 by bolts, and a through hole is provided at the bottom of the body 1 for matching with the output shaft of the motor. The output shaft passes through and is fixedly connected with the rotating seat 26, thereby driving the rotating seat 26 to rotate through the second motor 27.

[0040] Furthermore, the fixing structure 28 may include a fixed clamping block 29, a movable clamping block 30 and a spring 31. The fixed clamping block 29 is fixedly mounted on the rotating seat 26. The rotating seat 26 is provided with a mounting block 32 and a limiting groove 33. A sliding block is convexly provided at the bottom end of the movable clamping block 30 to slide in cooperation with the limiting groove 33, and the movement of the movable clamping block 30 toward the fixed clamping block 29 can be limited by the limiting groove 33.

After installation, the spring 31 is in a compressed state to provide a driving force for the movable clamping block 30 to move toward the fixed clamping block 29. When the copper bowl 4 is fixed, the movable clamping block 30 is driven to move back to the fixed clamping block 29. After the copper bowl 4 is placed between the movable clamping block 30 and the fixed clamping block 29, the movable clamping block 30 is released, so that the movable clamping block 30 moves toward the fixed clamping block 29 under the action of the elastic force of the spring 31, and cooperates with the fixed clamping block 29 to clamp the copper bowl 4. Preferably, the copper bowl 4 can be cylindrical, and the fixed clamping block 29 and the movable clamping block 30 are both arc-shaped plates that cooperate with the outer surface of the copper bowl 4, thereby improving the stability of clamping the copper bowl 4.
