Abstract
Description
Technical Field
[0001] This utility model relates to the field of jaw crusher technology, and in particular to a jaw crusher with screening function. Background Technology
[0002] Jaw crushers, widely used in mining, building materials, and metallurgy, primarily rely on two animal-like jaw plates: one fixed and one movable. The rotation of an eccentric shaft drives the movable jaw plate to perform periodic reciprocating motion, thereby applying compressive force to the material entering the crushing chamber. When the material is placed between the two jaw plates, the movable jaw plate gradually approaches the fixed jaw plate, and the enormous pressure crushes the material into smaller particles. This crushing method is simple and direct, capable of handling ores and rocks of various hardnesses, and has a large processing capacity. It also has a relatively compact structure and is easy to install and maintain.
[0003] While existing jaw crushers perform excellently in material crushing, effectively improving crushing efficiency by using the regular opening and closing motion of the movable and fixed jaw plates to avoid incomplete crushing due to a single impact, they cannot directly screen the crushed material. Because the crushed material is discharged directly from the discharge port without an effective screening device, subsequent processing requires additional screening equipment, increasing equipment costs and floor space. Furthermore, the unscreened material discharged necessitates secondary manual sorting to meet specific particle size requirements, consuming significant manpower and resources and reducing overall production efficiency. Utility Model Content

[0030] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings. 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.
[0031] Reference Figure 1 , Figure 2 and Figure 3 This utility model provides an embodiment of a jaw crusher with screening function, including a workbench 1, a crusher body 3 fixedly installed on the top of the workbench 1, a movable jaw plate 4 provided inside the crusher body 3, a fixed plate 5 fixedly connected to the bottom right side of the workbench 1, a vibrating motor 6 fixedly installed in the middle of the top wall of the fixed plate 5, a screening frame 7 fixedly installed at the top of the vibrating motor 6, and electric telescopic rods 8 fixedly installed at both the front and rear ends of the bottom left side of the workbench 1. The output ends of the two electric telescopic rods 8 are respectively fixedly connected to the front of the screening frame 7. A material conveyor belt 9 is provided at the bottom right end of the workbench 1 on the rear left side. A collection box 10 is provided at the bottom left end of the workbench 1. The collection box 10 is located at the bottom left end of the screening frame 7. A drive assembly is provided at the top left side of the crusher body 3. A dust removal mechanism 2 is provided at the bottom center of the workbench 1. The drive assembly includes a drive motor 11, which is fixedly installed at the left end of the crusher body 3. A drive wheel 12 is provided at the rear side of the crusher body 3. A transmission belt 13 is provided at the output end of the drive motor 11 and the outer wall of the drive wheel 12.
[0032] Specifically, after the material is fed into the crusher body 3, the drive motor 11 located at the left end of the crusher body 3 starts, providing initial energy for the entire crushing process. The output end of the drive motor 11 is connected to the drive wheel 12 located at the rear of the crusher body 3 via a transmission belt 13. When the drive motor 11 rotates, it drives the drive wheel 12 to rotate synchronously with the help of the transmission belt 13. The drive wheel 12 then drives the movable jaw plate 4, a key component inside the crusher body 3, to perform periodic reciprocating motion. The movable jaw plate 4 moves closer to and away from the fixed jaw plate. Under the pressure of both, the material is crushed into smaller particles. The crushed material falls into the screening frame 7. After the vibration motor 6 on the fixed plate 5 at the bottom of the screening frame 7 starts, it generates high-frequency vibration, causing the screen to vibrate. The screen frame 7 vibrates synchronously, allowing fine materials that meet the finished product particle size to fall through the screen. At the same time, the two electric telescopic rods 8 on the bottom left of the workbench 1 can adjust the tilt angle of the screen frame 7 as needed. To speed up screening, the screen frame 7 can be tilted by changing the state of the telescopic rods, allowing the material to flow faster under vibration. After screening, qualified materials fall onto the material conveyor belt 9 and are transported to the subsequent process. Large particles remaining in the screen frame 7 gather at the bottom left and slide into the collection box 10, waiting for secondary crushing. In addition, when the equipment is running, especially during crushing operations, dust is generated, the dust removal mechanism 2 forms a water mist around the crusher to capture the dust, causing it to agglomerate and settle. This allows the crusher to effectively remove dust while crushing and screening materials, improving production efficiency and protecting the working environment.
[0033] Reference Figure 1 and Figure 5 The dust removal mechanism 2 includes a water storage tank 201, which is located at the bottom center of the workbench 1. A booster water pump 202 is fixedly installed on the front right end of the water storage tank 201. The input end of the booster water pump 202 is connected to the front right end of the water storage tank 201. The output end of the booster water pump 202 is connected to a water supply pipe 203. Both output ends of the water supply pipe 203 are connected to a diversion pipe 204. Multiple atomizing nozzles 205 are fixedly installed on the opposite sides of the two diversion pipes 204. A water injection pipe 206 is connected to the front left end of the water storage tank 201. A sealing valve 207 is fixedly installed at the top of the water injection pipe 206.
[0034] Specifically, the water storage tank 201 is located at the bottom center of the workbench 1. When the equipment starts running, especially when the crusher body 3 is crushing materials, a large amount of dust is generated. At this time, the booster water pump 202 located at the front right end of the water storage tank 201 starts and draws water from the water storage tank 201. Thanks to its pressurization function, it can provide sufficient power for subsequent water spraying dust removal. The water drawn by the booster water pump 202 flows into the water supply pipe 203 through the output end. The water supply pipe 203 evenly distributes the water to two branch pipes 204. The branch pipes 204 allow the water to be delivered to different locations. Multiple atomizing nozzles 205 installed on the opposite side of the branch pipes 204, under pressure... After the water reaches the atomizing nozzle 205, the nozzle atomizes the water flow into tiny water droplets. These tiny water droplets form a dense water mist area around the bottom of the crusher. Since dust is hydrophilic, when it comes into contact with the water mist, the dust particles will be adsorbed onto the water droplets, and then agglomerate and settle, effectively reducing the emission of dust into the surrounding environment during the crushing process and achieving the purpose of dust removal. In order to ensure that there is a continuous and sufficient water source in the water storage tank 201, a water injection pipe 206 is installed at the front left end of the water storage tank 201. When the water level in the tank drops, the water can be injected into the water storage tank 201 by opening the sealing valve 207 at the top of the water injection pipe 206, ensuring that the dust removal operation can be carried out without interruption.
[0035] Reference Figure 1 and Figure 4 A control console 14 is fixedly installed on the front left side of the workbench 1. The control console 14 is electrically connected to the booster water pump 202 and the drive motor 11 respectively. A push handle 15 is fixedly connected to the left side of the collection box 10. An anti-slip sleeve 16 is fixedly connected to the left end of the push handle 15. Limiting plates 17 are fixedly connected to the front and rear sides of the left side of the workbench 1. Limiting grooves 18 are opened on the adjacent side of the two limiting plates 17. Two sliding ears 19 are fixedly connected to the front and rear sides of the collection box 10. The collection box 10 is slidably connected inside the two limiting plates 17 through the two limiting grooves 18 and multiple sliding ears 19. Anti-slip pads 20 are fixedly connected to the four corners of the bottom of the workbench 1. The bottom of the multiple anti-slip pads 20 is designed to be anti-slip. A cooling fan 21 is fixedly installed on the top of the drive motor 11. A dustproof net 22 is fixedly installed on the front side of the cooling fan 21.
[0036] Specifically, the control console 14, located at the front left side of the workbench 1, is electrically connected to the booster pump 202 and the drive motor 11. Before starting the equipment, the operator sets the speed and torque parameters of the drive motor 11 through the control console 14 to match the crushing requirements of different materials. At the same time, the power of the booster pump 202 is adjusted according to the dust situation to ensure the best dust removal effect. After starting, the control console 14 monitors the operating status of both in real time to ensure stable operation. After the material enters the crusher body 3, the drive motor 11 starts to work, and the cooling fan 21 on its top runs synchronously. Based on the heat exchange principle, the heat generated by the drive motor 11 is quickly dissipated. The dustproof net 22 on the front side of the cooling fan 21 effectively blocks external dust from entering the motor, avoiding the impact of dust accumulation on heat dissipation and motor performance. The performance ensures that the drive motor 11 outputs power stably for a long time, driving the drive wheel 12 to reciprocate the movable jaw plate 4 via the transmission belt 13, crushing the material. The crushed material falls into the screening frame 7, and the high-frequency vibration of the vibrating motor 6 promotes screening. Qualified material falls to the material conveyor belt 9 and is sent away. Large particles remaining in the screening frame 7 are tilted to the left by the electric telescopic rod 8. The sliding ears 19 on the front and rear sides of the collection box 10 are slidably connected to the limiting groove 18 of the limiting plate 17 in the workbench 1, which not only ensures that the collection box 10 stably receives materials, but also facilitates removal and cleaning. The push handle 15 and anti-slip sleeve 16 on the left side of the collection box 10 make it easy for workers to grab and apply force to easily move the collection box 10 out for dumping. The anti-slip pads 20 at the four corners of the bottom of the workbench 1 increase the friction with the ground and prevent the equipment from vibrating and shifting during operation.
[0037] Working Principle: As material is fed into the crusher body 3, the movable jaw plate 4 inside the crusher body 3 begins to play a crucial role. Driven by the drive assembly, the movable jaw plate 4 performs periodic reciprocating motion, moving closer and further away from the interior of the crusher body 3. When the movable jaw plate 4 approaches the fixed jaw plate inside the crusher body 3, the material between them is subjected to compressive force, and the material is gradually crushed into smaller particles. This compression crushing method can efficiently process materials of various hardnesses, ensuring their size meets subsequent processing requirements. The crushed material falls through the opening at the bottom of the crusher body 3 into the screening frame 7. The vibration source of the screening frame 7 is the vibrating motor 6 on its bottom fixed plate 5. After the vibrating motor 6 starts, it generates high-frequency vibration, causing the screening frame 7 to vibrate synchronously. During the vibration process, small materials that meet the size requirements can pass through the screen at the bottom of the screening frame 7 and fall downwards, while larger particles that have not yet reached the finished product particle size standard are crushed. Granular materials remain in the screening frame 7. Meanwhile, the two electric telescopic rods 8 on the left side of the bottom of the workbench 1 can flexibly adjust the tilt angle of the screening frame 7 according to actual production needs. When it is necessary to speed up the screening, the electric telescopic rods 8 can be extended or shortened to make the screening frame 7 present a suitable tilt state, allowing the material to flow to the left under the action of vibration, thereby improving screening efficiency. The qualified material after screening falls directly onto the material conveyor belt 9 below, which will transport these finished materials to the next process. The unqualified large particles remaining in the screening frame 7 will slide into the collection box 10 set at the bottom left end of the screening frame 7 after accumulating to a certain amount. Due to the tilt of the screening frame 7, they will slide into the collection box 10 set at the bottom left end. The collection box 10 is used to temporarily store these materials to be crushed again, so that they can be sent back to the crusher body 3 for further crushing. This cycle is repeated to realize continuous crushing and screening of materials, effectively improving production efficiency and product quality.
[0038] Furthermore, the dust removal mechanism 2 optimizes the working environment and enhances the overall practicality of the equipment. The water storage tank 201 is located at the bottom center of the workbench 1. When the equipment starts running, especially when the crusher body 3 is crushing materials, a large amount of dust will be generated. At this time, the booster water pump 202 located at the front right end of the water storage tank 201 starts and draws water from the water storage tank 201. Thanks to its pressurization function, it can provide sufficient power for subsequent water spray dust removal. The water drawn by the booster water pump 202 flows into the water supply pipe 203 through the output end. The water supply pipe 203 evenly distributes the water to two branch pipes 204. The branch pipes 204 allow the water to be delivered to different locations. Multiple atomizing nozzles 205 installed on the opposite side of the branch pipes 204 atomize the water into tiny water droplets after the pressurized water reaches the atomizing nozzles 205. These tiny water droplets form a fine mist area around the bottom of the crusher. Because dust is hydrophilic, when it comes into contact with the water mist, the dust particles are adsorbed onto the water droplets, and then agglomerate and settle, effectively reducing the emission of dust into the surrounding environment during the crushing process and achieving the purpose of dust removal. In order to ensure that there is a continuous and sufficient water source in the water storage tank 201, a water injection pipe 206 is installed at the front left end of the water storage tank 201. When the water level in the tank drops, the water can be injected into the water storage tank 201 by opening the sealing valve 207 at the top of the water injection pipe 206, ensuring that the dust removal operation can be carried out without interruption. While the various components of the crusher work together to crush and screen materials, the dust removal mechanism 2 continues to operate, which not only protects the health of the workers on the production line, but also meets environmental protection requirements, and comprehensively improves the performance of the jaw crusher with screening function.
