Description

Technical Field

[0001] The utility model belongs to the technical field of building construction, in particular to a crushed stone aggregate screen for cement-stabilized crushed stone base construction. Background Art

[0002] The cement-stabilized gravel base layer has the function of stabilizing the foundation, reducing foundation settlement and improving the bearing capacity of the road surface. Cement-stabilized gravel uses graded gravel as aggregate, adopts a certain amount of cementitious material and sufficient mortar volume to fill the gaps in the aggregate, and is compacted by paving in an embedded manner. Before laying the cement-stabilized gravel, it is necessary to control the aggregate screen to screen the gravel according to the particle size. The main components of the aggregate screen include a vibration motor, a screen mesh and a mounting frame.

[0003] After searching, a patent document with patent announcement number CN214938987U discloses a compact cement stabilized gravel base construction gravel aggregate screen, including a bottom frame fixedly connected with a shock absorbing spring, the top of the shock absorbing spring is fixedly connected with a support frame, the bottom of the support frame is fixedly connected with a vibration motor, the bottom of the inner cavity of the support frame is fixedly connected with a first motor, the first motor is connected with a first gear through a power output shaft, the upper part of the first gear is meshed with a first rack, the bottom surface of the first rack is fixedly connected with a fixed frame, the side wall of the fixed frame is welded with a slide bar and slides with a slideway provided on the support frame, and the inner wall of the fixed frame is fixedly connected with a screen. It allows the stones accumulated on the screen to be quickly dispersed, does not form accumulation and blockage, and is convenient for cleaning the equipment, making the screening more sufficient.

[0004] However, it still has the following disadvantages in actual use:

[0005] The existing dense cement stabilized gravel aggregate screen for gravel base construction, during use, starts the first motor to make the screen shake left and right, and starts the vibration motor to make the screen shake, but the electrical equipment used for gravel screening is increased, which will increase the power consumption, and the operation steps are complicated, which increases the workload of the staff;

[0006] 2. The existing dense cement-stabilized gravel base construction gravel aggregate screen, during use, starts the water pump to spray the water in the water tank on the filter, and starts the second motor to adjust the position of the nozzle to increase the cleaning range of the filter. However, the nozzle will move out of the fixed frame during the movement, resulting in water waste, and more electrical equipment is started during the screen cleaning process, increasing power consumption.

[0007] To this end, we provide a crushed stone aggregate screen for cement-stabilized crushed stone base construction to solve the above-mentioned problems. Utility Model Content
