[0019] In order to more clearly explain the overall concept of the present utility model, the following will be described in detail by way of examples in conjunction with the accompanying drawings of the specification.
[0020] As Figures 1 to 3 shown, the embodiment of the present utility model proposes an asphalt concrete screening equipment, including a screening machine 1. Triangular fixing frames 8 are fixedly installed on both sides of the inner wall of the screening machine 1. Sieve plates 7 are slidably connected to the inner walls of the two triangular fixing frames 8. Two through holes 9 are opened on one side of the screening machine 1;
[0021] On one side of the screening machine 1, there is a screening mechanism, and the screening mechanism includes a fixed rod 6, a connecting plate 5, a rotating plate 4, a rotating shaft 3, and a motor 2. On the left side of one side of the screening machine 1, a motor 2 is fixedly installed. The output shaft of the motor 2 is fixedly installed with a rotating shaft 3 that penetrates and extends outside the screening machine 1. Two rotating plates 4 are fixedly installed on the outer ring of the rotating shaft 3. On one side of the sieve plate 7, two fixed rods 6 are fixedly installed. On one side of the two fixed rods 6, connecting plates 5 that are engaged with the rotating plates 4 are fixedly installed.
[0022] Specifically, on the other side of the sieve plate 7, two sliding rods 10 are fixedly installed. Both of the two sliding rods 10 penetrate and extend outside the through hole 9. The sieve plate 7 that moves is limited by the sliding rods 10, and the sieve plate 7 screens the concrete.
[0023] Specifically, at one end of the two sliding rods 10 located outside the through hole 9, mounting plates 11 are fixedly installed. On one side of the two mounting plates 11, reset springs 12 are fixedly installed. The reset springs 12 are fixed by the mounting plates 11, and the reset springs 12 drive the mounting plates 11 to reset.
[0024] Specifically, in the middle of both sides of the two screening machines 1, L-shaped fixing plates 13 are fixedly installed. Both of the two L-shaped fixing plates 13 are fixedly connected to the reset springs 12. The other ends of the reset springs 12 are fixed by the L-shaped fixing plates 13.
[0025] Specifically, on one side of the screening machine 1, a discharge chute 15 is provided. A guiding inclined plate 14 is fixedly installed on the inner wall of the discharge chute 15. The guiding inclined plate 14 guides the concrete screened by the sieve plate 7, and the discharge chute 15 discharges the concrete on the guiding inclined plate 14.
[0026] Specifically, four support legs 16 are fixedly installed at the bottom of the screening machine 1. The screening machine 1 is fixedly supported by the support legs 16.
[0027] Working principle: Pour the concrete onto the sieve plate 7, then start the motor 2 to drive the rotating shaft 3 to rotate, which drives the two rotating plates 4 to move and squeeze the connecting plate 5, and drives the sieve plate 7 to move within the triangular fixing frame 8 through the fixed rod 6. At the same time, when the sieve plate 7 moves, it drives the mounting plate 11 to move by sliding the sliding rod 10 in the through hole 9, and stretches the reset spring 12. When the rotating plate 4 is separated from the connecting plate 5, at this time, under the potential energy action of the reset spring 12, the sieve plate 7 will perform a return action to screen the concrete. The screened concrete is conveyed to the discharge chute 15 through the guiding inclined plate 14 and discharged, and the concrete can be screened, which is convenient for subsequent better construction use.
