Description

Technical Field

[0001] This utility model relates to the field of jaw crusher design, and in particular to a high-efficiency dustproof and sealed jaw crusher. Background Technology

[0002] Jaw crushers are widely used in the primary crushing of materials such as ores and rocks in industries such as mining, construction materials, metallurgy, and chemicals. With increasingly stringent environmental standards and safety requirements, the dust pollution and poor sealing issues generated by traditional jaw crushers during the crushing process urgently need to be addressed. High-efficiency dustproof and sealed jaw crushers, through optimized dustproof structures and sealing designs, have become key equipment for improving the environmental friendliness and safety of crushing operations, and are of great significance in promoting the green transformation of industrial production.

[0003] Traditional jaw crushers lack effective dust control measures, allowing large amounts of dust generated during crushing to escape directly into the working environment. This not only deteriorates air quality in the workshop, harming the respiratory health of operators, but also poses a potential safety hazard such as dust explosions. This is because the feed inlet and crushing chamber lack a sealed design, allowing dust to easily diffuse outwards through gaps. Traditional dust collection systems often use simple bag filters or natural sedimentation, with loose connections between the dust collection pipes and the crusher body, and cumbersome filter component replacement. For example, some equipment uses bolted-on dust filter plates, requiring machine shutdown and disassembly of multiple components for maintenance, which is time-consuming and labor-intensive. Frequent disassembly also causes wear on seals, further reducing dust collection efficiency. Furthermore, the feed inlet cover has a rudimentary sealing structure, secured only by simple clips, which is insufficient to withstand vibrations during crushing, leading to dust leakage from the feed inlet and affecting the overall efficiency of the dust collection system.

[0004] In response to this technical problem, this application proposes a high-efficiency dustproof and sealed jaw crusher. Utility Model Content

[0005] The purpose of this invention is to address the shortcomings of existing technologies by proposing a high-efficiency, dustproof, and sealed jaw crusher that avoids clogging the air pump.

[0024] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0025] Reference Figure 1 and Figure 3 An embodiment of this utility model provides a high-efficiency dustproof and sealed jaw crusher, including a dustproof protective cover 1. Pre-set support plates 2 are fixedly connected to both the left and right ends of the bottom side of the dustproof protective cover 1. A jaw crusher body 8 is installed inside the dustproof protective cover 1. A pre-set guide pipe 3 is fixedly connected to the top side of the dustproof protective cover 1. The outer wall of the pre-set guide pipe 3 penetrates the outer wall of the dustproof protective cover 1. A guide pipe cap 4 is rotatably connected to the top front end of the pre-set guide pipe 3. A pre-set connecting block 10 is fixedly connected to the middle rear end of the guide pipe cap 4. A pre-set fixing plate 12 is fixedly connected to the top rear end of the guide pipe cap 4. The pre-set fixing plate 12 is connected to the pre-set connecting block 10 via an arc-shaped clamp 15. A dust removal pipe 5 is fixedly connected to the left side of the dustproof protective cover 1. A dust filter plate 16 is installed inside the dust removal pipe 5. Two pre-set flange rings 18 are installed on the outer wall of the dust removal pipe 5. Adjusting rods 17 are slidably connected to the outer walls of the two pre-set flange rings 18. An adjusting shaft 11 is rotatably connected to the top front side of the pre-set feed pipe 3. The outer wall of the adjusting shaft 11 is fixedly connected to the bottom front side of the feed pipe cover 4. A sealing block 9 is fixedly connected to the bottom side of the feed pipe cover 4. A reserved feed inlet 6 is opened on the top side of the jaw crusher body 8, and a reserved discharge outlet 7 is opened on the bottom side of the jaw crusher body 8. The left end of the dust removal pipe 5 is connected to an external air pump. The position of the pre-set feed pipe 3 corresponds to the position of the reserved feed inlet 6.

[0026] Specifically, the operator first opens the guide pipe cover 4 of the preset guide pipe 3 and adds the material to be crushed. Since the preset guide pipe 3 and the reserved feed inlet 6 of the jaw crusher body 8 are on the same central axis, the material can fall precisely into the crusher, preventing spillage. After starting the jaw crusher body 8, the material is crushed and discharged from the reserved discharge outlet 7 on the bottom side. The entire feeding and crushing process is smooth and seamless, ensuring efficient completion of the crushing task.

[0027] Reference Figure 2 A preset placement plate 14 is fixedly connected to the top side of the preset fixing plate 12. Two arc-shaped clamping plates 15 are rotatably connected to the top side of the preset placement plate 14. A return spring 13 is provided on the top side of the preset fixing plate 12. One end of the return spring 13 is connected to the bottom side of the two arc-shaped clamping plates 15, and the other end is connected to the top side of the preset placement plate 14.

[0028] Specifically, during the crushing process, the dust cover 1 effectively blocks debris and dust from splashing. An external air pump draws dust from inside the dust cover 1 through the dust removal pipe 5. The dust filter plate 16 inside the dust removal pipe 5 intercepts and filters the dust, preventing dust accumulation from affecting the air pump performance. When the dust filter plate 16 needs to be replaced, the operator rotates the preset adjustment ring 21, using the threaded connection to disengage the preset limit block 22 at the left end of the adjustment rod 17 from the semi-slot engagement position of the preset adjustment ring 21. After removing the preset adjustment ring 21, the two preset flange rings 18 are unfolded, allowing the old filter plate to be easily removed and replaced with a new one. The maintenance process requires no tools and is convenient to operate.

[0029] Reference Figure 4 A pre-installed mounting plate 20 is fixedly connected to the right side of the pre-installed flange ring 18. An adjusting knob 23 is rotatably connected to the right side of the pre-installed mounting plate 20. Adjusting slide rods 17 are slidably connected inside both pre-installed flange rings 18. A pre-installed adjusting ring 21 is provided at the left end of the adjusting slide rod 17. The threaded connection post at the right end of the adjusting slide rod 17 is on the inner wall of the adjusting knob 23. Two pre-installed limiting strips 19 are fixedly connected to the outer wall of the adjusting slide rod 17. A pre-installed limiting block 22 is fixedly connected to the left end of the adjusting slide rod 17.

[0030] Specifically, to further enhance sealing, the guide pipe cover 4 needs to be closed when the jaw crusher body 8 is working. At this time, the sealing block 9 on the bottom side of the guide pipe cover 4 is tightly engaged with the top of the pre-set guide pipe 3. At the same time, the arc-shaped clamping plate 15 is pressed to open it. The pre-set connecting block 10 is placed between the clamping plates and then released. The arc-shaped clamping plate 15 elastically holds the pre-set connecting block 10, forming a double sealing structure, which effectively prevents dust from escaping from the feed inlet, ensuring dust prevention throughout the crushing process and creating a clean working environment.

[0031] Working principle: When using this utility model, the operator first opens the guide pipe cover 4 on the preset guide pipe 3 and adds the material to be crushed into the preset guide pipe 3. The preset guide pipe 3 and the reserved feed port 6 on the jaw crusher body 8 are on the same central axis. When the material enters the preset guide pipe 3, it can accurately enter the jaw crusher body 8. At this time, the operator starts the jaw crusher body 8 to crush the material. After the material is crushed, it can be discharged through the reserved discharge port 7 on the bottom side of the jaw crusher body 8.

[0032] During the crushing process, debris and dust will be generated. To prevent debris and dust from splashing, a dustproof protective cover 1 can be installed on the outside of the jaw crusher body 8 to remove dust during the operation of the jaw crusher body 8.

[0033] Furthermore, the dust inside the dustproof protective cover 1 can be connected to the dust removal pipe 5 via an external air pump, thereby removing the dust from the inside of the dustproof protective cover 1 through the dust removal pipe 5. The dust filter plate 16 installed inside the dust removal pipe 5 can filter the dust, preventing excessive accumulation from affecting the working effect of the external air pump. If the dust filter plate 16 needs to be replaced, the operator can rotate the preset adjustment ring 21 to disengage the preset limit block 22 at the left end of the adjustment rod 17 from the engagement position with the semi-through groove reserved inside the preset adjustment ring 21 under the action of the threaded connection, thereby removing the preset adjustment ring 21 through the through groove position, allowing the two preset flange rings 18 to be unfolded, and the dust filter plate 16 embedded inside can be taken out for replacement.

[0034] To prevent dust from flying out of the preset guide pipe 3, when the jaw crusher body 8 starts working, the guide pipe cover 4 is closed. The sealing block 9 on the bottom side of the guide pipe cover 4 is engaged with the top of the inside of the preset guide pipe 3. At the same time, the operator presses the arc-shaped clamping plate 15 so that the preset connecting block 10 can enter between the two arc-shaped clamping plates 15. The arc-shaped clamping plates 15 are then released to clamp the preset connecting block 10, thereby increasing the sealing of the device.

[0035] 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. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
