It is widely used in the screening of aggregates of different specifications in the production of sand and gravel aggregate mines. In the dry production line of sand and gravel aggregate, sand and gravel fall directly from the belt conveyor to the screen of the vibrating screen. The material is relatively concentrated and cannot be distributed on the entire screen surface, so the ideal screening effect of the vibrating screen cannot be achieved, and the screening efficiency of the vibrating screen cannot be guaranteed. Utility Model Content
[0003] The utility model aims to provide a material distribution device which can fully utilize the screening area of the vibrating screen through uniform material distribution and greatly improve the screening efficiency of the vibrating screen.
[0004] To this end, the utility model adopts the following technical solutions:

[0006] Furthermore: an adjustment track is arranged on the side of the position adjustment plate, and a limiting groove cooperating with the support rod is formed in the extension direction of the adjustment track, and there is a gap between adjacent limiting grooves.
[0007] Furthermore: the material guiding and dispersing portion of the bulk material baffle is arc-shaped, and the middle portion of the material guiding and dispersing portion protrudes relative to both sides in the horizontal direction.
[0008] Furthermore: a fixing block is arranged on the side of the bulk material baffle, a fixing groove cooperating with the adjusting rod is opened in the fixing block, and the fixing block is connected to the bulk material baffle by a fixing bolt.
[0009] Furthermore: the adjusting rod is provided with a limiting hole for the fixing bolt to pass through.
[0010] Furthermore: two groups of the adjusting rods are arranged along the material guiding direction of the material distribution hopper, and the ends of the adjusting rods are rotatably connected with a rotating shaft, one end of which is fixed to the side of the position adjustment plate.
[0011] Furthermore: a spring is connected between the top of the fixing frame and the bottom of the material distributing hopper.
[0012] Furthermore: a vibrator is installed at the bottom of the material distribution hopper.
[0013] Compared with the prior art, the utility model has the following beneficial effects:
[0014] The utility model uses a bulk material baffle, which can be adjusted up and down, front and back, and at an angle through a position adjustment plate and an adjustment rod according to the type of stone and the belt speed of the conveyor belt, so that the bulk material effect is better. At the same time, because the dispersed stones fall on the distribution hopper, and the vibrator will make the stones uniformly dispersed again before being discharged through the distribution hopper, the uniformly dispersed stones fall into the vibrating screen and cover the vibrating screen, giving full play to the screening area of the vibrating screen, greatly improving the screening efficiency of the vibrating screen.

DETAILED DESCRIPTION
[0019] The present invention is further described below in conjunction with the accompanying drawings and embodiments, but they are not intended to limit the present invention.
[0020] like Figure 1-3As shown, a vibrating screen material distribution device for a sand and gravel aggregate production line is provided, wherein a distribution hopper 3 is arranged between the feeding port of a belt conveyor 10 and the receiving port of the vibrating screen, a bulk material baffle 1 is arranged above the distribution hopper 3, a material guide and dispersion portion 12 is arranged on the side of the bulk material baffle 1 opposite to the feeding port of the belt conveyor 10, and a support rod 11 is arranged on the side of the bulk material baffle 1; a position adjustment plate 2 connected to the support rod 11 is arranged above the distribution hopper 3, an opening is arranged on the position adjustment plate 2 opposite to the feeding port of the belt conveyor 10, so that stones can contact the bulk material baffle 1 through the opening, an adjustment rod 6 is connected between the side of the position adjustment plate 2 and the side of the distribution hopper 3, and an adjustment structure is arranged on the adjustment rod 6 to adjust the orientation and angle of the material guide and dispersion portion 12 of the bulk material baffle 1 facing the feeding port of the belt conveyor 10.
[0021] The material guiding and dispersing portion 12 of the bulk material baffle 1 is arc-shaped, and the middle part of the material guiding and dispersing portion 12 protrudes relative to the two sides in the horizontal direction. In this embodiment, when the material falling from the belt conveyor 10 is received and guided by the arc-shaped material guiding and dispersing portion 12, it is more conducive to dispersing the material and dispersing it into the material distribution hopper 3, so as to achieve the primary material distribution effect of the overall transported stone.
[0022] Specifically, in order to easily adjust the distance between the bulk material baffle 1 and the feeding port of the belt conveyor 10 on the position adjustment plate 2, an adjustment track 21 is provided on the side of the position adjustment plate 2. The adjustment track 21 extends along the material guiding direction of the material distribution hopper 3. A limit groove 22 is provided on the bottom wall of the adjustment track 21, and there is a gap between adjacent limit grooves 22. In this way, the support rod 11 can be adjusted in position by moving on the adjustment track 21 and the final position can be confirmed by being placed in the limit groove 22 at the required adjustment position. At the same time, two groups of support rods 11 on the bulk material baffle 1 are symmetrically arranged, and a corresponding number of adjustment tracks 21 are provided accordingly.
[0023] In this embodiment, in order to make the initial bulking more uniform, a limiting hole 62 for the fixing bolt 7 to pass through is provided on the adjusting rod 6, and two groups of adjusting rods 6 are provided along the material guiding direction of the material distributing hopper 3, and the adjusting rods 6 of each group are symmetrically distributed on both sides of the horizontal direction of the material distributing hopper 3, and the ends of the adjusting rods 6 are rotatably connected with a rotating shaft 61, one end of which is fixed to the side of the position adjusting plate 2. Based on the above content, the adjusting rod 6 can adjust the cooperation between the fixing bolt 7 and a specific limiting hole 62 through the limiting holes 62 evenly provided at its lower end to achieve the upper and lower position adjustment of the bulk material baffle 1; at the same time, the adjusting rod 6 can achieve the angle adjustment of the material guiding and distributing part 12 of the bulk material baffle 1 relative to the feeding port of the belt conveyor 10 through the combined action of the rotating shaft 61 movably connected at its upper end and the limiting holes 62 evenly provided at its lower end. Therefore, by adjusting the upper and lower, front and back and angle of the bulk material baffle 1, it can adapt to the changes of different stone types and the belt speed of the conveyor belt, so as to make the initial bulking more uniform.
[0024] A fixing block 8 is disposed on the side of the bulk material baffle 1, and a fixing groove matching the adjusting rod 6 is provided in the fixing block 8. The fixing block 8 is connected to the bulk material baffle 1 by fixing bolts 7. The number of the fixing blocks 8 corresponds to the number of the adjusting rods 6.
[0025] Specifically, a fixing frame 4 is provided below the distribution hopper 3 so that the distribution hopper 3 can be placed on the ground. In addition, a spring 5 is connected between the top of the fixing frame 4 and the bottom of the distribution hopper 3. At the same time, a vibrator 9 is installed at the bottom of the distribution hopper 3 so that the stone can be dispersed secondary in the distribution hopper 3.
[0026] In this embodiment, the material outlet of the material distribution hopper 3 is matched in size with the material receiving opening of the vibrating screen, which is conducive to the stone material covering the entire screen surface of the vibrating screen.
