[0021] Stone crusher is an indispensable machine in quarry. In the process of stone crusher, a lot of dust is often generated and floats in the air. It will not only cause harm to the operator's body, but also pollute the environment. Therefore, the dust should be processed to avoid it from polluting the environment.

[0022] like Figures 1 to 4 As shown, the utility model provides an environmentally friendly stone crusher.

[0023] Specifically, by Figure 1-3 The invention provides a crushing box 1, comprising: a crushing box 1; a feeding piece 2 connected to the top of the crushing box 1; the feeding piece 2 is set to an inverted trapezoid for the convenience of feeding, a feeding piece 9 is connected to the bottom of the crushing box 1, and the feeding piece 9 is a truncated cone for the convenience of discharging, two crushing rollers 3 for crushing stones are rotatably connected to the crushing box 1, and a dustproof component is provided in the crushing box 1;

[0024] The dustproof component includes two mounting seats 4 symmetrically connected in the gravel box 1, and the opposite sides of the two mounting seats 4 are rotatably connected with a blocking plate 5, the bottom of the blocking plate 5 is rotatably connected with a compression spring 6, and the other end of the compression spring 6 is connected to the inner wall of the gravel box 1.

[0025] It should be noted that the crushing roller 3 is rotatably connected to the crushing box 1 to crush the stones. A driving motor is connected to one side of the crushing box 1 to drive the crushing roller 3 to rotate. This is the prior art and therefore no further explanation is given here. In the actual production process, a suitable compression spring 6 can be selected to ensure its spring stiffness so that the compression spring 6 can quickly respond to the weight of the stone to open the sealing plate, and will not quickly push the sealing plate 5 back to its original position after the stone passes through.

[0026] The utility model can prevent dust from overflowing from the feed member 2 into the external environment and causing environmental pollution by setting a dust-proof component. When the stone is poured into the crushed stone box 1, the stone can first hit the blocking plate 5. At this time, the gravity of the stone itself can overcome the elastic force of the compression spring 6 to open the two blocking plates 5. When the stone passes through, the two blocking plates 5 are affected by the compression spring 6 and close again, thereby preventing dust from overflowing from the crushed stone box 1 and causing environmental pollution.

[0027] Specifically, Figure 3 As shown, a diverter roller 7 is rotatably connected in the crushing box 1, and the diverter roller 7 is located below the feeding member 2. A servo motor 8 for driving the diverter roller 7 to rotate is connected to one side of the crushing box 1.

[0028] It should be noted that the diverter roller 7 is composed of a mounting roller and a plurality of diverter plates.

[0029] In the utility model, the driving servo motor 8 can drive the diverter roller 7 to rotate, and then the stones after feeding can be affected by the rotating diverter roller 7 to produce a diverter effect, thereby avoiding the situation where too many stones enter at one time and cause the blocking plate 5 to be stuck.

[0030] As another specific implementation of the utility model, the utility model provides an environmentally friendly stone crusher.

[0031] Specifically, Figure 2 As shown, two symmetrical sealing blocks 10 are connected to the gravel box 1, and the two sealing blocks 10 are symmetrically arranged on the front and rear sides of the diverter roller 7.

[0032] In the utility model, this setting can be used in conjunction with the diverter roller 7 to enhance the diverter effect of the diverter roller 7.

[0033] In one specific implementation manner, the utility model provides an environmentally friendly stone crusher.

[0034] Specifically, Figure 1 As shown, a water storage tank 11 is connected to one side of the gravel box 1, an exhaust fan 17 for extracting dust in the gravel box 1 is connected to the water storage tank 11, and an air outlet pipe 14 is connected to the water storage tank 11.

[0035] In the utility model, the exhaust fan 17 can guide the dust accumulated in the gravel box 1 into the water storage tank 11. Since the water storage tank 11 is pre-injected with water, the dust introduced into the water storage tank 11 can be discharged through the air outlet pipe 14 after being purified.

[0036] In one specific implementation manner, the utility model provides an environmentally friendly stone crusher.

[0037] Specifically, Figure 3 As shown, a fixed frame 12 is connected to one side of the gravel box 1, and a filter screen 13 for filtering stones is detachably connected inside the fixed frame 12. One side of the gravel box 1 and one side of the fixed frame 12 are both provided with air inlets for dust to pass through.

[0038] In the present invention, when the exhaust fan 17 extracts dust from the gravel box 1, some small stones may enter the exhaust fan 17 due to the negative pressure. Therefore, in order to protect the exhaust fan 17, the filter screen 13 can be used to filter out some small stones.

[0039] In one specific implementation manner, the utility model provides an environmentally friendly stone crusher.

[0040] Specifically, Figure 4 As shown, one end of the filter screen 13 extends to the outside of the fixing frame 12 and is connected to a connecting plate 15, and two mutually symmetrical positioning bolts 16 are threadedly connected to the connecting plate 15.

[0041] In the present invention, the filter screen 13 can be conveniently pulled out from the fixing frame 12 by unscrewing the positioning bolts 16 from the connecting plate 15 , and then the filter screen 13 can be cleaned.

[0042] Working principle: The dust-proof component can be set to prevent dust from overflowing from the feeder 2 into the external environment and causing environmental pollution. When the stones are dumped into the gravel box 1, the servo motor 8 is driven to drive the diverter roller 7 to rotate, and then the fed stones can be affected by the rotating diverter roller 7 to produce a diverter effect. The stones then hit the blocking plate 5. At this time, the gravity of the stones themselves can overcome the elastic force of the compression spring 6 to open the two blocking plates 5. When the stones pass through, the two blocking plates 5 are affected by the compression spring 6 and close again, thereby preventing dust from overflowing from the gravel box 1 and causing environmental pollution.

[0043] The exhaust fan 17 can guide the dust accumulated in the gravel box 1 into the water storage tank 11. Since water is injected into the water storage tank 11 in advance, the dust introduced into the water storage tank 11 can be discharged through the air outlet pipe 14 after being purified.

[0044] The above is only a preferred embodiment of the present invention, and does not constitute any form of limitation to the present invention. Although the present invention has been disclosed as a preferred embodiment as above, it is not intended to limit the present invention. Any technician familiar with this patent can make some changes or modifications to equivalent embodiments of equivalent changes using the technical content suggested above without departing from the scope of the technical solution of the present invention. The implementation schemes in the above embodiments can also be further combined or replaced. However, any simple modifications, equivalent changes and modifications made to the above embodiments based on the technical essence of the present invention without departing from the content of the technical solution of the present invention are still within the scope of the present invention.
