Description

Technical Field

[0001] The invention relates to the technical field of ore construction, in particular to a crushing device for open-pit limestone mine crushing construction. Background Art

[0002] Ore refers to a mineral aggregate from which useful components can be extracted or which itself has certain properties that can be utilized. It can be divided into metallic minerals and non-metallic minerals. The unit content of useful components (elements or minerals) in an ore is called the ore grade. Precious metal ores such as gold and platinum are expressed in grams per ton, and other ores are often expressed in percentages. Ore grade is often used to measure the value of an ore, but the composition of the vein stone (useless minerals in the ore or minerals with very little useful components and cannot be used) and the amount of harmful impurities in the ore of the same effective component also affect the value of the ore. In order to facilitate the transportation of large pieces of ore, large pieces of ore are generally crushed into smaller pieces through an ore crushing device.

[0003] The existing Chinese patent publication number is CN112892709B. The invention discloses an ore crushing device. The ore is put into the main body of the device through the feed channel, and the driving device is turned on. The driving device causes the two crushing rollers to rotate. The crushing roller on the left rotates clockwise, and the crushing roller on the right rotates counterclockwise. The crushing blocks on the two crushing rollers will crush the ore on the top. The crushed ore will stay on the top of the screening mechanism under the action of gravity, and then be screened.

[0004] Although the device can screen the crushed ore, it is unable to perform secondary crushing on the larger ore after screening to meet the qualification requirements, resulting in the possibility of requiring other devices for subsequent crushing, which greatly reduces the practicality and increases the cost.

[0005] Therefore, a crushing device is needed for the construction of open-pit limestone mines. Summary of the invention

[0006] In order to solve all or part of the above problems, the purpose of the present invention is to provide a crushing device for open-pit limestone mine crushing construction, so as to solve the problem that the crushing device proposed in the above-mentioned comparative document technology cannot perform secondary crushing of larger ores after screening, resulting in reduced practicality and increased cost.

[0007] To achieve the above-mentioned purpose, the present invention provides the following technical solutions: a crushing device for open-pit limestone mine sliding construction, comprising a device main body, a crushing mechanism is arranged inside the device main body, a screening mechanism is arranged inside the device main body, dust reduction mechanisms are installed on both sides of the device main body, a supporting member is arranged below the screening mechanism, a conveying mechanism 1 is arranged inside the supporting member, an output mechanism is arranged inside the device main body, a conveying mechanism 2 is arranged on one side of the upper end of the device main body, the device main body comprises a protection box 1, a protection box 2 is fixedly installed at one end of the protection box 1, the crushing mechanism comprises a fixing member fixedly connected to the inside of the protection box 2, a servo motor 1 is fixedly installed at the lower end of the fixing member, a rotating shaft is fixedly installed at the output end of the servo motor 1, an end of the rotating shaft away from the servo motor 1 passes through the protection box 1, the rotating shaft is rotatably connected to the protection box 1, a crushing roller 1 is fixedly installed at one end of the rotating shaft, the crushing roller 1 is rotatably connected to the protection box 1, a gear 1 is installed on the outer side of the rotating shaft, a gear 2 is meshed with one side of the gear 1, a driven shaft is fixedly installed at one end of the gear 2, and the driven shaft is fixed at one end of the driven shaft away from the gear 2 A crushing roller 2 is installed, the crushing roller 2 is rotatably connected with a protection box 1, the crushing roller 2 is matched with the crushing roller 1, the screening mechanism includes a tripod, pads are fixedly installed on both sides of the lower end of the tripod, a hydraulic rod is fixedly installed at the lower end of the pad, the lower end of the hydraulic rod is fixedly connected with the dust reduction mechanism, a screening plate is arranged in the middle of the tripod, when the device starts to work, the servo motor 1 drives the rotating shaft to rotate, the rotating shaft drives the gear 1 and the crushing roller 1 to rotate, because the gear 2 is in meshing state with the gear 1, the gear 2 is driven to drive the driven shaft and the crushing roller 2 to rotate, at this time, the crushing Roller 1 and crushing roller 2 rotate in opposite directions, and the ore in the middle is squeezed and crushed efficiently. The crushed ore falls from the middle, and the qualified ore falls from the screening plate, while the unqualified ore rolls to both sides. At the same time, the hydraulic rod pushes the upper component up, so that the distance between the screening plate and crushing rollers 1 and 2 is shortened, so that the unqualified ore will be crushed for the second time, so that only a small amount of ore continues to roll to both sides, which greatly increases the qualified rate of ore crushing. It not only completes the screening function but also has the effect of secondary crushing, thereby improving the practicability of the device.

[0010] Furthermore, a plurality of fixed bars are fixedly installed on the outer surface of the conveyor belt, baffles are fixedly installed on both sides of the fixed bars, and the baffles are fixedly connected to the conveyor belt.

[0018] The present invention provides a crushing device for open-pit limestone mine crushing construction. When the device starts working, a servo motor 1 drives a rotating shaft to rotate, and the rotating shaft drives a gear 1 and a crushing roller 1 to rotate.
