Description

Technical Field

[0001] The utility model relates to the technical field of recycled aggregates, in particular to recycled aggregate crushing equipment. Background Art

[0002] With the development of urbanization in my country, the emission of construction waste has increased year by year, and the proportion of renewable components has also been increasing. However, most of the construction waste is transported to the suburbs or around the city for simple landfill or open-air storage without any treatment, which not only wastes land and resources, but also pollutes the environment. On the other hand, with the increasing population, the demand for sand and gravel aggregates in the construction industry has continued to grow. For a long time, due to the wide availability and low price of sand and gravel aggregates, they have been considered to be inexhaustible raw materials and have been mined at will, resulting in resource depletion, landslides, and riverbed diversions, which have seriously damaged the natural environment. The production and utilization of recycled aggregates from construction waste are of great significance to saving resources, protecting the environment and achieving sustainable development of the construction industry. Aggregates prepared from waste concrete are called recycled concrete aggregates (recycled aggregates for short).

[0003] In the process of recycling construction waste, the recycled aggregate needs to be crushed first. Most of the existing crushing equipment uses jaw crushing equipment or rotary crushing equipment for crushing. During the crushing process, the driving equipment needs to continuously control the moving parts to reciprocate. In order to achieve stable crushing, the mass of the moving parts is usually large, and the energy consumption during continuous activity is large. In addition, this type of upper feeding and lower discharging method requires re-crushing of a small amount of waste that is not completely crushed. The energy utilization rate is low during use. For this reason, we propose a recycled aggregate crushing equipment. Utility Model Content

DETAILED DESCRIPTION

[0020] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all of the embodiments.

[0021] See also Figures 1 to 5The utility model provides a technical solution: a recycled aggregate crushing equipment, including a crushing frame 1, the outer side of the limit block 3 is fitted with the inner side of the crushing frame 1, the vertical section of the crushing frame 1 is U-shaped, the bottom surface of the crushing block 4 is located above the top surface of the middle part of the crushing frame 1, and the setting of the crushing frame 1 plays a role in cooperating with the crushing block 4 to crush. The horizontal setting of the crushing frame 1 and the crushing block 4 can assist in completely crushing construction waste during use, facilitate the use of the equipment, and improve the practicability of the equipment. At the same time, the setting of the limit block 3 plays a limiting role, which can limit the crushing block 4 to only move in parallel up and down. The outer side of the crushing frame 1 is fixedly supported by a first support frame 2, and the left and right sides of the first support frame 2 are fixedly supported by a second support frame 7. The inner side of the second support frame 7 is movably covered with a connecting plate 8, and a supporting ring 9 is fixedly installed on the side of the connecting plate 8 facing the first support frame 2. The inner side of the supporting ring 9 is fixedly covered with a supporting block 10. A crushing piece is arranged above the crushing frame 1, and a driving motor 11 is supported on the outer side of the second support frame 7. The driving motor 11 is used to control the connecting plate 8 to continuously move. The movable shaft 6 is controlled to reciprocate up and down through the support block 10. The connecting sleeve 5 is driven to rise during the movement of the movable shaft 6, and then the crushing block 4 is raised. At the moment when the movable shaft 6 and the support block 10 are separated, the connecting sleeve 5 and the crushing block 4 will fall downward. The gravity of the crushing block 4 itself can be used to continuously crush the waste. The gravitational potential energy of the crushing block 4 itself can effectively reduce the waste of energy. The crushing parts include a limit block 3, a crushing block 4, a connecting sleeve 5, and a movable shaft 6. The movable shaft 6 is located between the two connecting plates 8. The connecting sleeve 5 is movably mounted on the outside of the movable shaft 6. The bottom surface of the connecting sleeve 5 is fixedly connected to the top surface of the crushing block 4. The front and rear ends of the crushing block 4 are respectively connected to the limit block 3. In the process of the movable shaft 6 being driven to move by the support block 10, the cooperation of the limit block 3 and the crushing block 4 can effectively avoid the movement of the crushing block 4 and the limit block 3, which is convenient for the use of the equipment, improves the practicability of the equipment, and facilitates the use of the equipment.

[0022] A feeding frame 12 is fixedly installed on the right side of the crushing frame 1, and a fixed support block 13 is fixedly installed above the feeding frame 12. The right side of the movable support block 17 is fitted with the left side of the fixed support block 13, and the top surface of the movable support block 17 and the top surface of the fixed support block 13 are located on the same inclined plane. The output shaft of the servo motor 15 is used to control the rotation of the threaded rod 16. The threaded rod 16 and the servo motor 15 will push the movable support block 17 to move to the left under the restriction of the limit plate 14, and the movable support block 17 is used to push out all the crushed waste materials, which is convenient for the feeding and discharging of the waste materials. The internal movable sleeve of the fixed support block 13 is provided with a limit plate 14, and the left end of the limit plate 14 is fixedly connected with the movable support block 17. The bottom surface of the right end of the limit plate 14 is fixedly installed with the servo motor 15, and the left side of the output shaft of the servo motor 15 is fixedly connected with the threaded rod 16. The setting of the limit plate 14 plays a role in limiting the servo motor 15 and the threaded rod 16, which can prevent the servo motor 15 from rotating in the opposite direction without support.

[0023] The vertical cross-section of the support block 10 is semi-arc-shaped, and the height value of one end of the support block 10 is greater than the height value of the other end. The outer side of the support block 10 is in contact with the inner wall of the support ring 9. The setting of the support block 10 plays a role in pushing the movable shaft 6 to rise, and at the same time can instantly release the movable shaft 6, which facilitates the use of the equipment and improves the practicability of the equipment.

[0024] In summary, when the recycled aggregate crushing equipment is used, the rotation of the connecting plate 8 is first controlled by the driving motor 11, so that the connecting plate 8 drives the support ring 9 and the support block 10 to rotate during the rotation, and the support of the support block 10 is used to make the support block 10 push the movable shaft 6 and the connecting sleeve 5 to move upward, so that the crushing block 4 moves upward synchronously, so that a gap flows out between the crushing block 4 and the crushing frame 1, and then the waste is sent to the top of the crushing frame 1 through the fixed support block 13 and the movable support block 17, and then the driving motor 11 is used to control the continuous rotation of the connecting plate 8, and the support ring 9 and the support block 10 are synchronously driven to rotate during the rotation of the connecting plate 8. The support block 10 can control the movable shaft 6 to reciprocate up and down. During the movement of the movable shaft 6, the connecting sleeve 5 will be driven to rise, and then the crushing block 4 will be raised. At the moment when the movable shaft 6 and the support block 10 are separated, the connecting sleeve 5 and the crushing block 4 will fall downward, and the gravity of the crushing block 4 itself can continue to crush the waste. After the crushing is completed, the crushing block 4 is controlled to rise, and then the output shaft of the servo motor 15 is used to control the rotation of the threaded rod 16. The threaded rod 16 and the servo motor 15 will push the movable support block 17 to the left under the restriction of the limit plate 14, and the movable support block 17 can be used to push out all the crushed waste.
