[0002] Cone crushers are a type of crushing machinery suitable for raw materials in the metallurgical, construction, road building, chemical, and silicate industries. Depending on the crushing principle and product particle size, they are available in many models. Crushers are widely used in mining, smelting, building materials, highways, railways, water conservancy, and chemical industries. Cone crushers have a large crushing ratio, high efficiency, low energy consumption, and uniform product particle size, making them suitable for medium and fine crushing of various ores and rocks.

[0003] To prevent excessive material inside the cone crusher from affecting the crushing effect, some cone crushers typically have a material control structure at the feed inlet. For example, Chinese Patent Publication No. CN219745095U discloses "A Material Control Cone Crusher", which controls the material to enter the cone crusher body by setting a material control component, thereby avoiding excessive material falling and causing blockage, as well as the cone crusher body becoming inefficient due to excessive material inside. At the same time, a protective component is used to protect the material control component, preventing it from losing its working effect due to material impact during operation.

[0004] In actual use, when the cone crusher is feeding, the ore and dust entering the crusher will cause dust to fly around. At the same time, when the cone crusher is crushing the ore, it will generate a lot of dust, which will pollute the environment. Utility Model Content

[0005] The purpose of this invention is to solve the shortcomings of existing technologies, such as dust flying during feeding and the generation of a large amount of dust during ore crushing, which pollutes the environment. Therefore, a cone crusher for crushing stone is proposed.

The dust removal device includes an exhaust assembly, a filter screen, a cleaning mechanism, and a drive structure. The cleaning mechanism is poweredly connected to the drive structure. A mounting plate that cooperates with the filter screen is fixedly installed inside the dust removal device, and the cleaning mechanism is mounted on the mounting plate.

[0007] Furthermore, the cleaning mechanism includes a fixed frame slidably connected to the mounting plate, and a plurality of cleaning brushes are provided on the fixed frame, the bristles of the cleaning brushes being in contact with the filter screen.

[0008] Furthermore, the drive structure includes a first gear rotatably disposed within the dust removal device, and a spur rack that meshes with the first gear is fixedly disposed on the cleaning mechanism.

[0009] Furthermore, a sector gear is rotatably installed inside the dust removal device, and a second gear that meshes with the sector gear is fixedly installed on the first gear, and a swing arm is fixedly installed on one side of the sector gear.

[0010] Furthermore, the dust removal device is rotatably equipped with a cam, the swing arm has a slot, the cam is eccentrically equipped with a rod that is movably inserted into the slot, and the dust removal device is equipped with a stepper motor that is powered by the cam.

[0011] Furthermore, the exhaust assembly includes a mounting cover, within which fan blades are rotatably disposed, and within which a dual-axis motor, which is poweredly connected to the fan blades, is fixedly disposed.

[0012] Furthermore, a filter cloth is fixedly installed on the mounting cover, and one output shaft of the dual-axis motor passes through the filter cloth and is fixedly connected to a brush.

[0013] The cone crusher for crushing stone proposed in this utility model has the following advantages: In this invention, a dust removal device and a dust collection hood are used to absorb the dust flying from the cone mill, and the dust is collected in the dust removal device for further dust removal before being discharged, thereby avoiding environmental pollution.

[0016] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0017] Reference Figure 1-4 A cone crusher for crushing stone includes a body 1, a feed hopper 2 on the body 1, a crushing structure 3 inside the body 1, a dust collection hood 4 on the body 1, and a dust removal device 5 on one side of the body 1. The air inlet of the dust removal device 5 is connected to the dust collection hood 4 through a connecting pipe. The dust removal device 5 includes an exhaust assembly 51, a filter screen 52, a cleaning mechanism 53, and a drive structure 54. The cleaning mechanism 53 is poweredly connected to the drive structure 54. A mounting plate 55 that cooperates with the filter screen 52 is fixedly installed inside the dust removal device 5, and the cleaning mechanism 53 is installed on the mounting plate 55.

[0018] In this invention, the dust removal device 5 and the dust collection hood 4 work together to absorb the dust flying from the cone mill feed hopper 2 and collect the dust back to the dust removal device 5 for dust removal before discharge, thereby avoiding environmental pollution. In some embodiments, the dust removal device 5 is equipped with a detachable dust collection box located below the filter screen 52 to collect the filtered dust.

[0019] Furthermore, in this embodiment, the cleaning mechanism 53 includes a fixed frame 531 slidably connected to the mounting plate 55. The fixed frame 531 is provided with a plurality of cleaning brushes 532. The bristles of the cleaning brushes 532 are in contact with the filter screen 52. When the fixed frame 531 moves, the plurality of cleaning brushes 532 move synchronously to clean the filter screen 52. Slider blocks are provided on both sides of the fixed frame 531, and corresponding grooves are provided on the mounting plate 55 to limit the movement trajectory of the fixed frame 531.

[0020] Furthermore, in this embodiment, the drive structure 54 includes a first gear 541 rotatably disposed within the dust removal device 5, and a rack 542 that cooperates with the first gear 541 is fixedly disposed on the cleaning mechanism 53. When the first gear 541 rotates, it drives the rack 542 and the fixed frame 531 to move. In some embodiments, the rack 542 can be replaced with teeth arranged in equal intervals.

[0021] It should be noted that, in this embodiment, a sector gear 543 is rotatably arranged inside the dust removal device 5, and a second gear that meshes with the sector gear 543 is fixedly arranged on the first gear 541. A swing arm is fixedly arranged on one side of the sector gear 543. When the swing arm swings, the sector gear 543 rotates, thereby driving the second gear to rotate. The second gear drives the first gear 541 to rotate. The outer diameter of the second gear is smaller than that of the first gear 541.

[0022] Furthermore, in this embodiment, a cam 545 is rotatably mounted on the dust removal device 5, and a slot is formed on the swing arm. An insert rod is eccentrically mounted on the cam 545 and movably inserted into the slot. A stepper motor 546, which is poweredly connected to the cam 545, is mounted on the outer wall of the dust removal device 5. The output shaft of the stepper motor 546 passes through the dust removal device 5 and is fixedly connected to the cam 545. The stepper motor 546 drives the cam 545 to rotate, which in turn drives the swing arm of the sector gear 543 to swing back and forth, causing the sector gear 543 to rotate back and forth. This, in turn, drives the second gear and the first gear 541 to rotate back and forth, thereby driving the fixed frame 531 and the cleaning brush 532 to move back and forth to clean the filter screen 52.

[0023] In detail, in this embodiment, the exhaust assembly 51 includes a mounting cover 511. The dust removal device 5 has an air outlet corresponding to the mounting cover 511. A fan blade 512 is rotatably installed inside the mounting cover 511. A dual-axis motor 513, which is poweredly connected to the fan blade 512, is fixedly installed inside the mounting cover 511. A support plate is fixedly installed inside the mounting cover 511. The dual-axis motor 513 is fixedly installed on the support plate. The dual-axis motor 513 drives the fan blade 512 to rotate, thereby discharging the air inside the dust removal device 5 and forming a negative pressure. This allows the air containing dust to be drawn in along the connecting pipe and the dust collection hood 4. The dust collection hood 4 is provided with a protective plate to prevent gravel from entering the dust removal device. The protective plate has ventilation holes.

[0024] More specifically, in this embodiment, a filter cloth is fixedly mounted on the mounting cover 511. The filter cloth is tensioned and fitted onto the mounting cover 511. The filter cloth has through holes. One output shaft of the dual-axis motor 513 passes through the through holes of the filter cloth and is fixedly connected to a brush 514. The bristles of the brush 514 are in contact with the filter cloth. In some embodiments, the dust removal device 5 has a cleaning port corresponding to the filter cloth to facilitate the removal of fine dust filtered by the filter cloth.

[0025] Working method: During operation, the dual-shaft motor 513 drives the fan blades 512 to rotate, which discharges the air inside the dust removal device 5 to form a negative pressure, thereby drawing in dust-containing air along the connecting pipe and the dust collection hood 4, filtering the dust through the filter screen 52, and then discharging the filtered air. The stepper motor 546 drives the cam 545 to rotate, and the cam 545 drives the swing arm of the sector gear 543 to swing back and forth, which in turn drives the sector gear 543 to rotate back and forth, thereby driving the second gear and the first gear 541 to rotate back and forth, thus driving the fixed frame 531 and the cleaning brush 532 to move back and forth to clean the filter screen 52.

[0026] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
