Based on the embodiments in the present disclosure, all other embodiments obtained by ordinary technicians in the field without making creative work are within the scope of protection of the present disclosure.
[0024] Embodiment 1
[0025] like Figure 1-3 As shown, a conveyor belt provided with a sub-screen includes a sub-screen 1, a conveying device 2, a discharge port 3 and a support frame 4, wherein the support frame 4 is arranged inside the discharge port 3; the sub-screen 1 is installed on the support frame 4; the conveying device 2 is arranged below the discharge port 3; the middle of the sub-screen 1 is higher than the two side surfaces.
[0026] The sub-screening net 1 is composed of a plurality of sub-screening sheets 11 uniformly arranged in the horizontal direction and a plurality of fixing belts 12 uniformly arranged in the vertical direction, and the fixing belts 12 are fixedly connected to the sub-screening sheets 11 at the intersections. The sub-screening sheets 11 replace the iron wires in the prior art, and the sub-screening sheets 11 have a larger width. The sub-screening net 1 composed of the sub-screening sheets 11 and the fixing belts 12 has a more solid structure and is not easily damaged.
[0027] Two ends of a plurality of the sieve plates 11 are fixed to the inner wall of the material discharge port 3 ; two ends of a plurality of the fixing belts 12 are fixed to the inner wall of the material discharge port 3 .
[0028] The feed opening 3 is a conical feed opening, which is convenient for fixing the screen 1 and the support frame 4.
[0029] like Figure 4 , combined with Figure 3As shown, the support frame 4 includes a plurality of bottom beams 41, a plurality of support beams 42, a cross beam 43 and a plurality of V-shaped oblique beams 44, the bottom beam 41 is installed at the bottom of the discharge port 3; the lower end of the support beam 42 is fixed to the bottom beam 41, and the fixation here is welding or clamping, and the upper end of the support beam 42 is fixed to the cross beam 43, and the fixation here is welding or clamping; the cross beam 43 is installed at the upper part of the discharge port 3; the middle of the plurality of V-shaped oblique beams 44 is fixedly connected to the cross beam 43, and the two ends are fixed to the inner wall of the discharge port 3, and the fixation here is welding or wire winding; the middle of the V-shaped oblique beam 44 is higher than the two ends. The middle of the V-shaped inclined beam 44 rests on the cross beam 43, and the two ends of the V-shaped inclined beam 44 are fixed on the inner wall of the discharge port 3, wherein the horizontal planes of the two ends of the V-shaped inclined beam 44 are lower than the horizontal plane of the cross beam 43. When the sub-screen 1 is fixed on the inclined beam 44, the middle part is higher than the two side surfaces, and the stones screened out will be dispersed to both sides under the action of gravity.
[0030] The number of the bottom beams 41 is the same as the number of the support beams 42. Each support beam 42 is connected to a bottom beam 41.
[0031] like Figure 5 As shown, the conveying device 2 includes a motor 21 , a conveying path 22 and a screw transmission rod 23 , wherein the motor 21 is connected to the screw transmission rod 23 ; and the screw transmission rod 23 is installed inside the conveying path 22 .
[0032] The conveying path 22 is provided with a semicircular groove 221, the inner diameter of which is equal to the maximum outer diameter of the spiral transmission rod 23. The gap between the semicircular groove 221 and the spiral transmission rod 23 is ensured to be small, so as to prevent sand and gravel from leaking out of the gap during the rotation of the spiral transmission rod 23, thereby reducing the amount of sand and gravel conveyed by the spiral transmission rod 23.
[0033] The working principle is as follows: start the motor 21, and the spiral transmission rod 23 rotates. The staff pours sand and gravel from above the sub-screen 1. Large stones cannot pass through the sub-screen 1 and scatter to both sides of the sub-screen 1. The sand and gravel passing through the sub-screen 1 falls into the conveying path 22, and the spiral transmission rod 23 rotates and conveys the sand and gravel to the conveying device 2 to enter the next concrete production process. After the sand and gravel are screened and conveyed, turn off the motor 21, the spiral transmission rod 23 stops rotating, and the staff can clean up the large stones scattered on both sides of the sub-screen 1.
[0034] The utility model achieves the purpose of avoiding deformation of the sub-screen by designing a support frame to reinforce the sub-screen, wherein the middle of the sub-screen is higher than the two side surfaces, which is conducive to large stones moving to the edge of the sub-screen and avoiding clogging of the mesh holes. When the large stones are concentrated on the edge of the sub-screen, it is more convenient for staff to clean them.
