Description

Technical Field

[0001] This utility model relates to the field of jaw crusher technology, specifically a jaw crusher with a dust suppression structure. Background Technology

[0002] Jaw crushers consist of a crushing chamber formed by two jaw plates, a moving jaw and a stationary jaw. They are crushers that simulate the movement of an animal's jaws to complete the crushing operation. They are widely used in the crushing of various ores and large materials in industries such as mining and metallurgy, building materials, highways, railways, water conservancy, and chemicals.

[0003] A search revealed that the announcement number is CN218452222U, and the name is a jaw crusher, which includes: a main power unit, a transmission mechanism, a jaw crushing chamber, a jaw crusher feed hopper, a stationary jaw plate and a moving jaw plate assembly. Through research and analysis, it was found that although this utility model has the advantages of reasonable design and simple structure, it still has the following defects to a certain extent.

[0004] For example, if a jaw crusher lacks a dust removal function, it will generate a large amount of dust during the crushing process. The aforementioned jaw crusher cannot suppress the dust during the crushing process, resulting in dust flying everywhere, polluting the working environment, and affecting the health of personnel. At the same time, the lack of a dust suppression structure makes it difficult for personnel to handle materials during transportation due to the height of the dust suppression mechanism. In order to solve the above technical problems, we have designed a jaw crusher with a dust suppression structure. Utility Model Content

[0005] The purpose of this utility model is to provide a jaw crusher with a dust suppression structure, which has a spray dust suppression function to avoid dust pollution of the working environment, which is beneficial to the health of personnel. The dust suppression mechanism is easy to store and facilitates transportation. It solves the problems of being unable to suppress dust, which leads to pollution of the working environment and affects the health of personnel, and the inability to store the dust suppression structure, which affects normal transportation.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a jaw crusher with a dust suppression structure, comprising a crusher body, a supporting base plate welded to the left side of the front side of the crusher body, positioning screws welded to the four corners of the top of the supporting base plate, damping springs and movable cross plates respectively fitted on the surface of the positioning screws, a water storage tank connected to the top of the movable cross plate by bolts, a water pump connected to the top of the water storage tank by bolts, a water delivery pipe fixedly connected to the outlet of the water pump, plastic hoses fixedly connected to the front and rear sides of the top of the water delivery pipe, fixed cross plates welded to the top of the front and rear sides of the crusher body, a positioning mechanism fixedly connected to the left side of the bottom of the fixed cross plate, a movable slide rod slidably connected to the left side of the top of the fixed cross plate, a fixed water pipe fixedly connected to the top of the movable slide rod, and a nozzle fixedly connected to the surface of the fixed water pipe.

[0007] Preferably, the positioning mechanism includes a fixed shell, a connecting slide plate is slidably connected to the inner cavity of the fixed shell, a positioning insert plate is fixedly connected to the right side of the connecting slide plate, a pull rod is fixedly connected to the left side of the connecting slide plate, and a positioning spring is sleeved on the surface of the pull rod.

[0008] Preferably, the right side of the positioning insert extends through to the right side of the fixed housing, and the left side of the pull rod extends through to the outside of the fixed housing and is fixedly connected to a pull plate.

[0009] Preferably, a rubber damper is fixedly connected to the center of the top of the support base plate, and an installation nut is threaded onto the top of the positioning screw surface.

[0010] Preferably, the water inlet pipe of the water pump extends to the bottom of the inner cavity of the water storage tank, and a water injection hopper is fixedly connected to the left side of the top of the water storage tank.

[0011] Preferably, a transparent plate is fixedly connected to the front side of the water storage tank, and the top of the plastic hose is fixedly connected to the fixed water pipe.

[0012] Preferably, a through opening is provided on the left side of the top of the fixed horizontal plate, and insertion slots are provided on the top and bottom of the left side of the movable slide rod.

[0013] Preferably, reinforcing plates are welded between the left and right sides of the bottom of the support base plate and the crusher body, and the number of nozzles is several, arranged at equal intervals.

[0014] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0015] The water pump draws water from the storage tank and delivers it to a fixed water pipe through a water delivery pipe and a plastic hose. The water is then sprayed onto the dust at the crushing point through nozzles, which effectively prevents dust from flying everywhere, avoids dust pollution in the working environment, and is beneficial to the health of workers.

[0016] Pulling the lever outwards moves the positioning plate out of the bottom slot. After pressing down on the fixed water pipe and moving it to the lowest point, the positioning spring pushes the positioning plate into the top slot to position the movable slide rod. This reduces the height of the fixed water pipe, preventing it from colliding with the fixed water pipe during transport and making it easier to move the crusher. Attached Figure Description

Positioning screws 12 are welded to the four corners of the top of the support base plate 7. Vibration damping springs 8 and movable cross plates 9 are respectively fitted onto the surfaces of the positioning screws 12. By setting the vibration damping springs 8, the crusher has a vibration damping function, which can dampen the dust suppression components on the movable cross plate 9 during crusher operation, preventing long-term vibration from causing the mechanical structure to loosen and effectively extending its service life. A water storage tank 6 is bolted to the top of the movable cross plate 9. A water pump 14 is bolted to the top of the crusher body 1. A water delivery pipe 5 is fixedly connected to the outlet of the water pump 14. Plastic hoses 3 are fixedly connected to the front and rear sides of the top of the water delivery pipe 5. By setting the plastic hoses 3, the water pipe 2 can be moved up and down easily. Fixed horizontal plates 15 are welded to the top of the front and rear sides of the crusher body 1. A positioning mechanism 17 is fixedly connected to the left side of the bottom of the fixed horizontal plate 15. A movable slide rod 4 is slidably connected to the top of the fixed horizontal plate 15. A fixed water pipe 2 is fixedly connected to the top of the movable slide rod 4. A nozzle 23 is fixedly connected to the surface of the fixed water pipe 2.

[0024] Please see Figure 4 The positioning mechanism 17 includes a fixed shell 21, a connecting slide plate 20 is slidably connected to the inner cavity of the fixed shell 21, a positioning insert plate 22 is fixedly connected to the right side of the connecting slide plate 20, a pull rod 19 is fixedly connected to the left side of the connecting slide plate 20, and a positioning spring 18 is sleeved on the surface of the pull rod 19.

[0025] Please see Figure 4 The right side of the positioning plate 22 extends through to the right side of the fixed shell 21, and the left side of the pull rod 19 extends through to the outside of the fixed shell 21 and is fixedly connected to a pull plate. By setting the pull plate, it is easier for people to pull the pull rod 19.

[0026] Please see Figure 2 A rubber damper 11 is fixedly connected to the middle of the top of the support base plate 7. By setting the rubber damper 11, the viscoelasticity of rubber can be used to consume vibration energy. By generating internal friction during vibration, kinetic energy is converted into heat energy, thereby achieving vibration reduction effect. The top thread of the positioning screw 12 is fitted with an installation nut 10. By setting the installation nut 10, the movable horizontal plate 9 can be installed and positioned.

[0027] Please see Figure 3 The water inlet pipe of the water pump 14 extends to the bottom of the inner cavity of the water storage tank 6. A water inlet 13 is fixedly connected to the left side of the top of the water storage tank 6. By setting the water inlet 13, it is convenient to add water to the water storage tank 6.

[0028] Please see Figure 1A transparent plate is fixedly connected to the front of the water tank 6. By setting the transparent plate, it is convenient for people to see the water level in the water tank 6. The top of the plastic hose 3 is fixedly connected to the fixed water pipe 2.

[0029] Please see Figure 4 and Figure 5 A through opening 16 is provided on the left side of the top of the fixed horizontal plate 15. By providing the through opening 16, the movable slide rod 4 can be installed easily. The top and bottom of the left side of the movable slide rod 4 are provided with insertion slots 24.

[0030] Please see Figure 1 and Figure 3 The bottom of the support base plate 7 is welded with reinforcing plates on both the left and right sides and the crusher body 1. There are several nozzles 23, which are arranged at equal intervals.

[0031] In use, this device is connected to an external power supply and controller. The crusher body 1 is powered on and operates to crush materials. At this time, the water pump 14 is controlled to operate, drawing water from the water storage tank 6 and delivering it through the water delivery pipe 5 and plastic hose 3 to the fixed water pipes 2 on the front and rear sides respectively. Then, the water is sprayed onto the crushing opening of the crusher body 1 through the nozzles 23 to reduce dust. This dust suppression spraying effectively prevents dust from flying everywhere, avoids dust pollution in the working environment, and is beneficial to the health of workers. When the crusher needs to be moved, the fixed water pipes 2 on the front and rear sides are relatively high, which may cause difficulties in handling. If the fixed water pipe 2 is bent or damaged due to collision with external objects during the process, the pull rod 19 is pulled outward. The pull rod 19 drives the positioning plate 22 to move out of the bottom insertion slot 24 through the connecting slide plate 20. Then, the movable slide rod 4 is pressed down, and the fixed water pipe 2 moves downward. When it moves to the lowest point, the pull rod 19 is released, and the compressed positioning spring 18 releases its elasticity to push the positioning plate 22 into the top insertion slot 24 to position the movable slide rod 4. This can reduce the height of the fixed water pipe 2, avoid collision with the fixed water pipe 2 during transportation, and make it more convenient for the crusher to be transported.

[0032] In summary, this jaw crusher with a dust suppression structure, through the coordinated use of the crusher body 1, fixed water pipe 2, plastic hose 3, movable slide bar 4, conveying water pipe 5, water storage tank 6, water pump 14, fixed cross plate 15, positioning mechanism 17, nozzle 23, and insertion slot 24, solves the problems of being unable to suppress dust, resulting in a polluted working environment, affecting personnel health, and being unable to store the dust suppression structure, thus hindering normal handling.
