DETAILED DESCRIPTION
[0018] 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.
[0019] Reference Figure 1-Figure 3A coarse aggregate crushing and screening device for civil construction includes a box body 1, the upper end of the box body 1 is opened, two crushing shafts 2 are rotatably arranged in the box body 1, the shaft bodies of the two crushing shafts 2 are provided with crushing rollers 3, and two guide plates 5 are symmetrically arranged on the upper side of the box body 1, and the height of the opposite end of the two guide plates 5 is smaller than the height of the opposite end, so as to ensure that the coarse aggregate can be crushed between the two crushing rollers 3.
[0020] A rotating motor is fixedly installed at the rear end of the box body 1, and the output end of the rotating motor is fixedly connected to one of the crushing shafts 2. The front ends of the two crushing shafts 2 extend to the outside of the box body 1. The front shaft bodies of the crushing shafts 2 are fixedly sleeved with gears 4, and the two gears 4 are meshed together. A first screen 6 is arranged below the two crushing rollers 3 in the box body 1, and a first unloading plate 7 is arranged below the first screen 6. A second screen 8 is fixedly arranged at the lower end of the first unloading plate 7. The aperture of the first screen 6 is smaller than that of the second screen 8. The crushed coarse aggregate is coarse and fine. The finer coarse aggregate falls through the first screen 6, and the coarser coarse aggregate remains on the first screen 6, thereby realizing the screening of the coarse aggregate.
[0021] A second feed plate 9 is provided below the second screen 8. A left collecting port and a right collecting port 10 are respectively provided at the left and right ends of the box body 1. Both the first feed plate 7 and the second feed plate 9 are inclined, which is conducive to the coarse aggregate sliding down under its own gravity.
[0022] The left collecting port and the right collecting port 10 are provided with collecting boxes, which is more conducive to the subsequent processing of the coarse aggregate after screening.
[0023] The left end of the first unloading plate 7 is located at the left collecting port, and the right end of the second unloading plate 9 is located at the right collecting port 10. A shaking assembly is also provided on the box body 1. Specifically, the shaking assembly includes a rotating shaft 11 rotatably connected to the box body 1. The rotating shaft 11 is located below the first screen 6. A rotating wheel 14 is fixedly sleeved on the shaft body of the rotating shaft 11. A shift block 15 is fixedly connected to the outer side of the rotating wheel 14. The rotation of the rotating shaft 11 can drive the rotating wheel 14 to rotate, and the rotation of the rotating wheel 14 drives the shift block 15 to rotate. The rotation of the shift block 15 drives the first screen 6 to shake, which is more conducive to the initial screening of coarse aggregate after crushing. On the other hand, it speeds up the time for the coarse aggregate to slide to the lower right on the first screen 6, thereby improving the screening efficiency.
[0024] The crushing shaft 2 located on the right side and the shaft body of the rotating shaft 11 are both fixedly sleeved with sprockets 12, and a chain 13 is connected between the two sprockets 12. The rotating motor drives one of the crushing shafts 2 to rotate, and the rotating shaft 11 is driven to rotate through the cooperation of the two sprockets 12 and the chain 13, which drives the shifting block 15 to shift the first screen 6.
[0025] The above description is only a preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes within the technical scope disclosed by the present invention according to the technical scheme and the utility model concept of the present invention, which should be covered by the protection scope of the present invention.
