Technical Field

[0001] The utility model relates to the technical field of sandstone processing, in particular to a chute material dividing device for a screening machine. Background Art

[0002] When the sand and gravel processing system adopts the post-screening crushing process, the screened materials of each layer of screen are usually sent to different belt conveyors and then to the crushing equipment for crushing. In the design stage, the number of crushing equipment will be calculated according to the flow rate to meet the crushing needs. However, in the actual crushing and screening process, due to changes in the physical and chemical properties of the raw materials or other reasons, the amount of material screened out of a certain layer of screen after screening will increase, while the amount of material screened out of another layer of screen will decrease, resulting in an unbalanced crushing efficiency of the crushing equipment in the design, causing one crushing equipment to be full of aggregate in the crushing chamber, while the other crushing equipment has less aggregate in the crushing chamber, affecting the continuity of the sand and gravel processing system production.

DETAILED DESCRIPTION

[0018] See also Figure 1-4 A screening machine chute material dividing device comprises a chute 2, a collection box 3, a first chute 4, a second chute 5 and a movable baffle 6, wherein the collection box 3 is installed at the lower end of the chute 2, and two discharge ports 12 are arranged on the collection box 3. The first chute 4 and the second chute 5 are installed on the collection box 3 at the positions of the two discharge ports 12 respectively. The first chute 4 extends to the top of the first belt conveyor 10, and the second chute 5 extends to the top of the second belt conveyor 11. The height of the discharge port 12 above the second chute 5 is higher than the height of the discharge port 12 above the first chute 4. The discharge port 12 located above the first chute 4 is installed with a movable baffle 6, and the movable baffle 6 is used to adjust the size of the discharge port 12.

[0019] After the material is screened by the screening equipment 1, it is fed to the aggregate box 3 through the chute 2. The aggregate box 3 is provided with two discharge ports 12, and the two discharge ports 12 are respectively connected to the first chute 4 and the second chute 5. Since the height of the discharge port 12 above the second chute 5 is higher than the height of the discharge port 12 above the first chute 4, the material will be discharged from the first chute 4 first. After the production of the crushing equipment downstream of the first belt conveyor 10 is saturated, the size of the discharge port 12 is adjusted by the movable baffle 6, and then the material flow entering the first belt conveyor 10 is controlled, so that the crushing equipment downstream of the first belt conveyor 10 can produce normally, and the excess material will gradually accumulate in the aggregate box 3, and then enter the second belt conveyor 11 from the second chute 5, and be sent to the crushing equipment downstream of the second belt conveyor 11 for crushing.

[0020] In one embodiment, see Figure 2 , 3 The movable baffle 6 is longitudinally provided with a sliding hole 13, and the collecting box 3 is provided with a limiting screw 8 above the discharge port 12. The sliding hole 13 of the movable baffle 6 passes through the limiting screw 8, and a nut 14 is screwed on the limiting screw 8. When the movable baffle 6 needs to be adjusted, the nut 14 is loosened, and the movable baffle 6 is moved up and down to adjust the size of the discharge port 12. After adjustment, the nut 14 is tightened.

[0021] For further information, see Figure 2 , 3The first chute 4 is respectively provided with limit plates 7 on both sides of the corresponding discharge port 12, and the movable baffle 6 is movably inserted and installed between the outer wall of the collecting box 3 and the limit plates 7. The movable baffle 6 is limited by the limit plates 7 to prevent the movable baffle 6 from deforming outwards under the impact of the material.

[0022] In this embodiment, in order to facilitate the operation of the movable baffle 6 when adjusting the movable baffle 6 , a handle 15 is provided on the movable baffle 6 .

[0023] In another implementation, see Figure 4 The first chute 4 is provided with limit plates 7 on both sides of the corresponding discharge port 12, and the movable baffle 6 is movably inserted and installed between the outer wall of the collecting box 3 and the limit plates 7. The movable baffle 6 is provided with a first pull plate 16, and the collecting box 3 is provided with a second pull plate 17 above the discharge port 12. The bolt 18 is movably passed through the first pull plate 16 and then threadedly engaged with the second pull plate 17, or the bolt 18 is movably passed through the second pull plate 17 and then threadedly engaged with the first pull plate 16. By rotating the bolt 18, the movable baffle 6 can be adjusted, and the adjustment is more convenient.

[0024] See also Figure 1 The material collecting box 3 is installed on a bracket 9. Preferably, the bracket 9 is supported on the ground, or supported on the first belt conveyor 10. The bracket 9 is welded with steel sections and is used to support the material collecting box 3.

[0025] See also Figure 3 The bottom wall of the material collecting box 3 is tilted downward toward the first chute 4 to facilitate the discharge of the material in the material collecting box 3.

[0026] The working principle or use process of the utility model:

[0027] In actual production, see Figure 1 Since less material enters the second belt conveyor 11 through the chute from the top screen of the screening device 1, less aggregate is contained in the crushing device downstream of the second belt conveyor 11, while more material enters the first belt conveyor 10 from the second screen of the screening device 1, which causes the aggregate to accumulate in the crushing chamber of the crushing device downstream of the first belt conveyor 10. Therefore, a collection box 3 is provided under the chute 2 of the second screen of the screening device 1 for diversion. Under the condition that the crushing device downstream of the first belt conveyor 10 can operate normally, the excess material enters the crushing device downstream of the second belt conveyor 11 from the second chute 5 for crushing, thereby balancing the crushing efficiency of the crushing equipment and improving the continuity of the production of the sand and gravel processing system.
