[0019] The present invention will be described in detail below with reference to the accompanying drawings and in combination with embodiments. It should be noted that the embodiments and features in the embodiments of the present invention can be combined with each other without conflict.

[0020] like Figures 1 to 4In the embodiment of the iron ditch castable material vibrating screen of the utility model shown, the iron ditch castable material vibrating screen includes a first screen box 1, a horizontal load-bearing platform 2 is fixedly connected to the outer side of the first screen box 1, a vibration spring 3 is fixedly connected under the load-bearing platform 2, a collecting hopper 4 is fixedly connected under the first screen box 1, a connecting portion 5 is provided on the top of the first screen box 1, and a detachable second screen box 6 is connected to the connecting portion 5, a plurality of second screen boxes 6 with different screen hole diameters can be stacked and installed on the first screen box 1, and a discharge port 7 is provided at one end of the first screen box 1 and the second screen box 6.

[0021] Specifically, according to the required particle size grading requirements, the second screen boxes 6 with different screen hole diameters are assembled on the first screen box 2 in order from small to large, and the iron ditch castable material to be screened is poured into the second screening box 6 on the top layer to make the vibrating screen vibrate. Under the action of vibration, small particles of material fall into the lower screening box, and large particles move to the discharge port 7 in the upper screening box. The lower screening box also screens smaller particles and medium particles, and screens downward layer by layer until the required particle classification is completed.

[0022] In one embodiment of the present application, preferably, a vibration motor 8 is fixedly connected to the outer wall of the first screen box 1 to provide vibration power for the vibrating screen.

[0023] In one embodiment of the present application, preferably, the vibration spring 3 is fixedly connected to the support frame 9, and the first screen box 1 is placed at an angle, which is conducive to the material in the screen box moving toward the discharge port 7 faster.

[0024] In one embodiment of the present application, preferably, the connecting part 5 includes an L-shaped support plate 51 on the top of the first screen box 1 and a connecting plate 52 at the bottom of the second screen box 6, the connecting plate 52 abuts against the vertical plate of the L-shaped support plate 51, and the top of the second screen box 6 is fixedly connected with the L-shaped support plate 51, which is used to connect the second screen box 6 of a standardized structure. In order to prevent the upper screen box from sliding in an inclined direction, which may cause unstable operation of the equipment, the L-shaped support plate 51 and the connecting plate 52 are connected by bolts.

[0025] In one embodiment of the present application, preferably, the first screen box 1 and the second screen box 6 are both provided with inclined screen plates 10, each screen plate 10 is consistent with the inclination direction of the screen box, and the inclination angle of each screen plate 10 is greater than the inclination angle of the screen box, so as to facilitate the flow of materials on the screen plates 10 and improve the screening efficiency.

[0026] In one embodiment of the present application, preferably, a rotating shaft 11 is provided at the bottom end of the sieve plate 10 of each screen box, and an axial hole 12 for the rotating shaft 11 to rotate is opened on each screen box, so that the sieve plate 10 can be rotated around the discharge port 7 to facilitate the adjustment of the inclination angle of the sieve plate 10. The inclination angle of the sieve plate 10 can be adjusted according to needs and screening efficiency.

[0027] In one embodiment of the present application, preferably, a sealing plate 13 is fixedly connected to the bottom of each screen box, and a spring 14 is provided on the sealing plate 13. The top end of the spring 14 is fixedly connected to the screen plate 10, and the bottom end of the spring 14 is fixedly connected to the sealing plate 13. When the second screen box 6 is stacked upward at an angle, the top of the screen box will be misaligned. The sealing plate 13 is used to prevent the material under the screen plate 10 from leaking out. The spring 14 is provided to buffer the material poured on the screen plate 10, and to prevent the material from flowing out of the discharge port 7 before being screened when there is too much material. Specifically, when too much material is poured, the screen plate 10 presses down the spring 14 to reduce the angle of the screen plate 10, thereby slowing down the flow rate of the material on the screen plate 10 so that the material is fully screened. As the weight of the material decreases, the spring 14 gradually resets, which not only ensures the screening quality but also improves the screening efficiency.

[0028] In summary, the vibrating screen for iron ditch castable material in the above embodiment of the utility model, specifically, according to the required particle size grading requirements, the second screen boxes 6 with different apertures are assembled from small to large in sequence on the first screen box 1, the vibration motor 8 is started, and the iron ditch castable material to be screened is poured into the second screening box 6 on the top layer, and the material compresses the inclined screen plate 10 downward with the spring 14 so that the inclination angle of the screen plate 10 is reduced, delaying the flow speed of the material on the screen plate 10, and under the action of vibration, the small particles of the material fall into the lower screening box, and the large particles move toward the discharge port 7 in the upper screening box. As the weight of the material decreases, the spring 14 gradually resets to accelerate the movement speed of the material toward the discharge port 7, and the material is screened downward layer by layer in the layers of the screen box until the required particle classification is completed. The device uses standardized screen boxes to be combined according to different screen hole apertures, so that the device can flexibly adapt to multi-stage screening, and the screen plate with adaptive inclination angle automatically adjusts the inclination angle according to the amount of material, which can not only ensure the screening quality when there is too much material, but also improve the screening efficiency.
