The upper jaw plate 2 and the lower jaw plate 10 are detachably installed on the inner wall of the crushing box 1 using existing methods. Two lower jaw plates 10 are provided, which, together with the upper jaw plate 2, form a jaw plate to crush the ore fed into the crushing box 1. A screen 9 is detachably installed on the inner wall of the crushing box 1. A dust collection box 3 is fixedly connected to the outer wall of the crushing box 1. Holes are provided on the side wall of the dust collection box 3 to suck in dust generated during the ore crushing process, preventing dust from spreading and affecting the health of workers and the surrounding environment. A fan box 4 is fixedly connected to the lower surface of the dust collection box 3. An existing negative pressure fan is installed inside the fan box 4, which sucks in dust into the dust collection box 3. A dust collection box 8 is fixedly connected to the lower surface of the fan box 4. The sucked-in dust falls into the dust collection box 8 under gravity and is collected for subsequent centralized cleaning. The inner wall of the dust collection box 8 is... A sprinkler 11 is installed in the dust collection box 8. A water pipe 5 is fixedly connected to the outer wall of the sprinkler 11, which is connected to an external water source to provide water flow to the sprinkler 11. A box stopper plate 6 is inserted into the inner wall of the dust collection box 8. When cleaning dust, the box stopper plate 6 can be removed to clean the dust collection box 8. A limit knob 12 is rotatably connected to the inner wall of the box stopper plate 6. The inner wall of the box stopper plate 6 has a hole that matches the limit knob 12. The limit knob 12 is rotatably connected to the inner wall of the hole. Rotating the limit knob 12 can adjust the box stopper plate. The limiting knob 12 of plate 6 is elastically connected to the inner wall of the box stopper plate 6 through a torsion spring 13. The inner wall of the box stopper plate 6 has a groove that matches the torsion spring 13. The torsion spring 13 is fixedly connected to the inner wall of the groove. The inner wall of the box stopper plate 6 is threaded through and connected to a drain pipe 7. The inner wall of the box stopper plate 6 is provided with a thread that matches the drain pipe 7. The drain pipe 7 is connected to an external water circulation system. The water in the dust collection box 8 carries the dust and is discharged through the drain pipe 7. After being treated at the treatment point, the water enters the circulation system for reuse.

[0020] Reference Figure 2 and Figure 5The lower toothed plate 10 is inserted into the inner wall of the upper toothed plate 2. The inner wall of the upper toothed plate 2 has a slot that matches the protrusion on the upper surface of the lower toothed plate 10. The protrusion on the lower toothed plate 10 is inserted into the inner wall of the slot. The inner walls of the upper toothed plate 2 and the lower toothed plate 10 are respectively threaded and connected with fixing bolts 14.

[0021] Reference Figure 1 , Figure 3 and Figure 4 The blower box 4 is fixedly connected to the outer wall of the crushing box 1, and the dust collection box 8 is fixedly connected to the outer wall of the crushing box 1. The outer wall of the crushing box 1 has holes, and the screen 9 is detachably installed on the inner wall of the holes. The screen 9 filters the impurities entering the dust collection box 3 to prevent the ore fragments generated during the crushing process from being sucked in and blocking the inlet of the dust collection box 3. The screen 9 can be removed for cleaning or replacement. The outer wall of the limit knob 12 is fixedly connected to one end of the torsion spring 13, and the other end of the torsion spring 13 is fixedly connected to the inner wall of the box stop plate 6. The limit knob 12 will stretch the torsion spring 13 during rotation. When resetting, the elasticity of the torsion spring 13 will drive the limit knob 12 to rotate and reset. Water is sprayed into the dust collection box 8 in the form of water mist through the small holes on the sprinkler 11. The outer wall of the limit knob 12 has a directional groove. The directional groove makes it easy to determine the direction of rotation when rotating the limit knob 12, ensuring that the limit knob 12 can be rotated to a position that can release the limit on the box stop plate 6.

[0022] Working principle: First, during the crushing of raw gold ore, the existing negative pressure fan in the blower box 4 filters the dust generated during the crushing process through the screen 9 and then sucks it into the dust collection box 3. The sucked-in dust then falls into the dust collection box 8 under the action of gravity. At the same time, the water pipe 5 provides water flow through the small holes on the sprinkler 11 to sprinkle into the dust collection box 8 to settle the dust. The settled dust and water flow together and are discharged through the drain pipe 7. When cleaning the dust collection box 8, simply rotate the limit knob 12 manually so that the slot on the limit knob 12 faces to the left to release the limit on the box stopper plate 6. At the same time, the torsion spring 13 is stretched, and the box stopper plate 6 is manually pulled out. After cleaning, the box stopper plate 6 is put back and the limit knob 12 is released. The limit knob 12 is reset under the action of the torsion spring 13, and the cleaning of the dust collection box 8 is completed.

[0023] When the device is in operation, the raw gold ore is put into the crushing box 1. After being crushed by the upper jaw plate 2 and lower jaw plate 10 on the left moving jaw and the upper jaw plate 2 and lower jaw plate 10 on the right fixed jaw, the ore falls out from the gap between the bottom of the two jaw plates.

[0024] When it is necessary to replace the worn lower tooth plate 10, simply use a tool to remove the fixing bolt 14, then pull out the lower tooth plate 10 so that the protrusion on the lower tooth plate 10 separates from the inner wall of the groove of the upper tooth plate 2. Replacement can be performed on one of the severely worn parts. Finally, tighten the fixing bolt 14 with a tool to complete the replacement of the worn part.

[0025] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features.
