[0002] In material crushing operations in industries such as mining and metallurgy, large gyratory crushers have become key equipment in the coarse crushing stage due to their efficient and stable crushing capabilities. The frame, as the core component of a large gyratory crusher, bears the heavy responsibility of supporting the overall structure and withstanding the huge impacts and loads during the crushing process. Its performance directly affects the reliability and service life of the equipment.
[0003] In the prior art, a large amount of dust is generated when the gyratory crusher frame is in use. The cast steel frame components often cannot protect against the generated dust, which can be inhaled by people and cause harm to their health. Furthermore, prolonged use of the dust can damage the equipment. Therefore, those skilled in the art provide a large cast steel gyratory crusher frame structure to solve the problems mentioned in the background art. Utility Model Content
[0004] The purpose of this utility model is to provide a large gyratory crusher frame cast steel structure to solve the problems in the above-mentioned technology.
[0005] This utility model provides the following technical solution: a large gyratory crusher frame cast steel structure, including a cast steel body, the top of the cast steel body is provided with a protective mechanism to prevent stone fragments from splashing, and a dustproof mechanism is provided above the protective mechanism.
[0006] The dustproof mechanism includes a water storage disc, a pressure boosting box is fixedly connected to the top of the water storage disc, the water storage disc is connected to the pressure boosting box, an air inlet pipe is connected to the upper surface of the pressure boosting box, a pressure boosting piston plate is slidably attached to the inner wall of the pressure boosting box, the top of the pressure boosting piston plate slides on the inner wall of the air inlet pipe, and a connecting pipe is connected to the bottom of the water storage disc.
[0007] The protective mechanism includes a protective ring fixedly connected to the upper surface of the cast steel body. The top of the protective ring has an annular groove, and two support columns are fixedly connected inside the annular groove.

[0013] Compared with the prior art, the beneficial effects of this utility model are:
[0014] 1. This utility model utilizes the coordinated components of a dustproof mechanism, including a water storage disc, a pressure chamber, an air inlet pipe, a pressure piston plate, and a connecting pipe. When the gas pushes the pressure piston plate to slide within the pressure chamber, it can pressurize the gas inside the pressure chamber. This pressurizes the liquid in the water storage disc through the connecting pipe into the nozzle, where it is sprayed out to form a mist of water vapor. This water vapor can combine with dust particles in the air, increasing their weight and causing them to settle. This effectively reduces dust generated during the crushing process, improves the working environment, and reduces the impact of dust on the health of operators and the damage to equipment.
[0015] 2. This utility model utilizes a protective ring, a spray disc, and a nozzle in its protective mechanism. The annular groove on the protective ring can block the flying of gravel to a certain extent. If the nozzle installed on the spray disc is a high-pressure nozzle, the sprayed water flow can hinder the flying of gravel. Combined with the obstruction of the spray disc itself, this further reduces the flying of gravel and avoids potential harm to the surrounding environment and personnel. Attached Figure Description

[0021] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention.
[0022] Please see Figures 1-4 As shown, this utility model provides a technical solution: a large gyratory crusher frame cast steel structure, including a cast steel body 1, a protective mechanism 2 for preventing stone fragments from splashing on the top of the cast steel body 1, and a dustproof mechanism 3 for dust prevention above the protective mechanism 2.
[0023] The dustproof mechanism 3 includes a water storage disc 31, a pressurization box 32 is fixedly connected to the top of the water storage disc 31, the water storage disc 31 is connected to the pressurization box 32, the upper surface of the pressurization box 32 is connected to an air inlet pipe 34, a pressurization piston plate 35 is slidably attached to the inner wall of the pressurization box 32, the top of the pressurization piston plate 35 slides on the inner wall of the air inlet pipe 34, and the bottom of the water storage disc 31 is connected to a connecting pipe 36.
[0024] The protective mechanism 2 includes a protective ring 21 fixedly connected to the upper surface of the cast steel body 1. The top of the protective ring 21 has an annular groove 22. Two support columns 23 are symmetrically fixedly connected in the annular groove 22. The ends of the two support columns 23 opposite to the annular groove 22 are jointly fixedly connected to a spray disc 24.
[0025] In practice, the water storage disc 31 is disc-shaped, possessing good water storage performance and structural stability. It is fixedly connected to the booster box 32 by high-strength bolts. The booster box 32 is a cylindrical box structure with two symmetrical sliding grooves on its inner wall. The design of these two sliding grooves provides a precise sliding track for the booster piston plate 35. The air intake pipe 34 is made of hard rubber, with one end connected to an external air source and the other end extending into the booster box 32. The booster piston plate 35 is a circular plate structure with its edge tightly sliding against the inner wall of the booster box 32. Its top is embedded in the inner wall of the air intake pipe 34, allowing it to slide up and down within the air intake pipe 34. When external high-pressure gas enters the pressurization box 32 through the inlet pipe 34, the gas pressure pushes the pressurization piston plate 35 downward, thereby compressing the gas in the pressurization box 32 and realizing the pressurization function. By setting the pressurization piston plate 35 to slide tightly against the inner wall of the pressurization box 32, the contact area of the gas is reduced, thereby increasing the pressure more quickly. The connecting pipes 36 are all connected to the water storage space inside the water storage disc 31 and are used to transfer water in the water storage disc 31. The protective ring 21 is firmly fixed to the upper surface of the cast steel body 1 by welding. The protective ring 21 is made of metal and has a ring structure, which can effectively block the splashing of gravel. The size of the annular groove 22 is adapted to the internal components, providing installation space for components such as the support column 23. The two support columns 23 are opposite to one end of the annular groove 22 and are fixedly connected to the spray disc 24 by welding. The spray disc 24 is a circular disc structure made of metal, which can further block the splashing of gravel and provide a place for the installation of the nozzle 25.
[0026] As one implementation method in this embodiment, please refer to Figures 1-3 As shown, the number of connecting tubes 36 is greater than or equal to one.
[0027] As one implementation method in this embodiment, please refer to Figures 1-4 As shown, multiple nozzles 25 are fixedly fitted onto the spray disc 24 in a circular array.
[0028] In practice, the nozzle 25 and the spray disc 24 are connected by threads for easy disassembly and maintenance. The nozzle 25 can be either a spray nozzle 25 or a high-pressure nozzle 25. When used in combination, it can further reduce the splashing of gravel while providing dust protection.
[0029] As one implementation method in this embodiment, please refer to Figures 1-3 As shown, the water storage disc 31 is connected to the booster tank 32.
[0030] In practice, the water storage disc 31 and the booster tank 32 are connected to each other through an internal channel. When the pressure in the booster tank 32 reaches a certain level, water can be forced into the water storage disc 31.
[0031] As one implementation method in this embodiment, please refer to Figures 1-3 As shown, the connecting pipe 36 corresponds one-to-one with the nozzle 25, and the water storage disc 31 is connected to the nozzle 25 through the connecting pipe 36.
[0032] In practice, the connecting pipe 36 corresponds one-to-one with the nozzle 25. The water storage disc 31 is connected to the nozzle 25 through the connecting pipe 36, so that the water in the water storage disc 31 can be transported to the nozzle 25 through the connecting pipe 36 under pressure. The nozzle 25 sprays out atomized water, thereby forming water mist in the steel casting work area and playing a role in dust prevention.
[0033] As one implementation method in this embodiment, please refer to Figures 1-4 As shown, the top of the water storage disc 31 is connected to a water inlet pipe 33.
[0034] In practice, one end of the water inlet pipe 33 is connected to an external water source, which facilitates the replenishment of water into the water storage disc 31 and ensures that the water storage disc 31 always has a sufficient amount of water.
[0035] As one implementation method in this embodiment, please refer to Figures 1-3 As shown, two sliding grooves are symmetrically opened on the inner wall of the booster box 32, and the booster piston plate 35 slides in the sliding grooves.
[0036] Working principle: First, the stones to be crushed are poured into the cast steel body 1. Then, clean water is filled into the water storage disc 31 through the water inlet pipe 33. After the water storage disc 31 is full of clean water, air is introduced into the pressure chamber 32 through the air pump and air inlet pipe 34. The introduction of air pushes the pressure boosting piston plate 35 to slide downward in the sliding groove on the inner wall of the pressure chamber 32, so that the pressure change in the pressure chamber 32 is transmitted to the water storage disc 31, causing the water in the water storage disc 31 to be crushed under pressure. Water is replenished or stored through the inlet pipe 33 connected to it. At the same time, the connecting pipe 36 at the bottom of the water storage disc 31 is connected one-to-one with the nozzle 25 on the spray disc 24 in the protective mechanism 2. The pressure drives the water in the water storage disc 31 to be sprayed out from the nozzle 25 through the connecting pipe 36 to form a spray. The spray combines with dust and settles to achieve dust prevention. If the installed nozzle 25 high-pressure water head can be connected with the protective ring 21 and the spray disc 24, it can prevent the splashing of gravel from causing harm to the surrounding environment and personnel.
[0037] The above embodiments are only used to illustrate the technical solution of this utility model, and are not intended to limit it.
