Description
Technical Field
[0001] The utility model belongs to the technical field of building aggregate production, and particularly relates to a multi-stage crushing device for building aggregates. Background Technique
[0002] In the construction industry, as the main component of building materials such as concrete and mortar, the quality and particle size of aggregates have an important impact on the performance of the final products. Therefore, crushing treatment of building aggregates is an indispensable link in the production process of building materials. Among them, the existing building aggregate crushing devices are divided into single-stage crushing devices and multi-stage crushing devices.
[0003] When the existing single-stage crushing device is in use, it can only perform primary crushing on building aggregates. However, the building aggregates after primary crushing often fail to achieve an ideal particle size distribution. Especially for large-sized materials, they need to be crushed multiple times to meet the requirements, which increases energy consumption and costs.
[0004] When the existing multi-stage crushing device is in use, although it can perform multiple crushing on building aggregates to make the building aggregates finer, due to different construction requirements, in some buildings during construction, not only fine building aggregates are needed, but also coarse building aggregates are required. However, the existing multi-stage crushing device cannot directly discharge the building aggregates after primary crushing.
[0005] Therefore, it is very necessary to invent a multi-stage crushing device for building aggregates. Content of the Utility Model
[0006] The purpose of the utility model is to provide a multi-stage crushing device for building aggregates to solve the problems mentioned in the background technique.
[0007] To solve the above technical problems, the utility model is realized through the following technical solutions:
[0008] The utility model relates to a multi-stage crushing device for building aggregates, which comprises a box body, a first crushing shaft, a second crushing shaft, a first motor, a guiding frame, a secondary crushing mechanism, a first conveyor belt and a second conveyor belt. The box body is fixed on the ground by expansion bolts, and the first crushing shaft and the second crushing shaft are rotatably installed inside the upper end of the box body through support bearings; the first crushing shaft and the second crushing shaft are meshed with each other, and one ends of the first crushing shaft and the second crushing shaft are connected by a gear set; the other end of the second crushing shaft is fixed to the output end of the first motor, and the first motor is fixed to the outer side of the box body by bolts; a guiding frame and a secondary crushing mechanism are sequentially arranged below the first crushing shaft and the second crushing shaft, and both the guiding frame and the secondary crushing mechanism are fixed to the inner wall of the box body; a first conveyor belt and a second conveyor belt are fixed inside the lower end of the box body, and a second motor and a third motor for driving the first conveyor belt and the second conveyor belt are fixedly installed on the box body.
[0009] Further, the guiding frame comprises a first rotating column, a first rotating plate, a second rotating column, a second rotating plate, a partition plate and a buffer plate. The first rotating column and the second rotating column are respectively rotatably installed inside the box body through support bearings. One ends of the first rotating column and the second rotating column are respectively fixed to the output ends of a corresponding fourth motor and a fifth motor, and the fourth motor and the fifth motor are respectively fixed to the outer side of the box body by bolts; a first rotating plate is fixed to the outer side of the first rotating column, and the other end of the first rotating plate is slidably connected to the inner wall of the box body through a slideway; a second rotating plate is fixed to the outer side of the second rotating column, and the other end of the second rotating plate is slidably connected to the inner wall of the box body through a slideway; a partition plate is arranged below the first rotating plate and the second rotating plate. The outer edge of the partition plate is fixed to the inside of the box body by welding, and the partition plate is arranged between the first conveyor belt and the second conveyor belt; a plurality of the buffer plates are arranged between one side of the partition plate close to the second conveyor belt and the inner wall of the box body. The buffer plates are fixed to the corresponding partition plate and the inner wall of the box body by welding, and the buffer plates are arranged obliquely; a secondary crushing mechanism is arranged between one side of the partition plate close to the first conveyor belt and the box body. With such a setting, it is possible to guide the building aggregates crushed by the first crushing shaft and the second crushing shaft, so as to facilitate directly guiding the building aggregates onto the second conveyor belt or guiding the building aggregates into the secondary crushing mechanism.
[0010] Further, the secondary crushing mechanism includes a third crushing shaft and a fourth crushing shaft. The third crushing shaft and the fourth crushing shaft are respectively rotatably installed inside the box body through support bearings. The third crushing shaft and the fourth crushing shaft are meshed with each other, and the third crushing shaft and the fourth crushing shaft are arranged above the first conveyor belt. One ends of the third crushing shaft and the fourth crushing shaft are connected by a gear set. The other end of the fourth crushing shaft is fixed to the output end of a sixth motor, and the sixth motor is fixed to the outer side of the box body by bolts. Such a setting can perform secondary crushing on construction aggregates.
[0011] Compared with the prior art, the utility model has the following beneficial effects:
[0012] 1. With the setting of the guiding frame of the utility model, when in use, if secondary crushing of construction aggregates is not required, the end of the first rotating plate far from the first rotating column can be moved away from the partition plate, and then the end of the second rotating plate far from the second rotating column can be moved closer to the partition plate. At this time, the construction aggregates crushed by the first crushing shaft and the second crushing shaft will, under the action of the second rotating plate, fall onto the buffer plate and then slide onto the second conveyor belt on the buffer plate. The buffer plate can prevent the construction aggregates from damaging the second conveyor belt. If secondary crushing of construction aggregates is required, the end of the first rotating plate far from the first rotating column can be moved closer to the partition plate, and then the end of the second rotating plate far from the second rotating column can be moved away from the partition plate. At this time, the construction aggregates crushed by the first crushing shaft and the second crushing shaft will, under the action of the first rotating plate, fall into the secondary crushing mechanism.
[0013] 2. With the setting of the secondary crushing mechanism of the utility model, when in use, the aggregates that need to be secondarily crushed will, under the action of the first rotating plate, fall between the third crushing shaft and the fourth crushing shaft. Then, the sixth motor drives the fourth crushing shaft and the third crushing shaft to rotate in opposite directions to perform secondary crushing on the construction aggregates. The construction aggregates after secondary crushing will fall onto the first conveyor belt. Description of the Drawings
