Description

Technical Field

Connecting rods 715 are fixedly connected to both ends of the connecting plate 714. An arc-shaped frame 712 is fixedly arranged on the connecting rod 715 close to one end of the arc-shaped block 711.

[0026] Specifically, by starting the servo motor 706, under the meshing transmission of the two gears 704, the two rotating rods 701 rotate towards each other, so that the material scattering rods 703 on the two rotating rods 701 can break up the agglomerated blocks of the material, making the material fall evenly into the material guiding box 3, improving the coal block sorting efficiency and the quality of coal blocks; when the servo motor 706 works, the rotating rod 707 drives the crank 709 to rotate, so that the arc-shaped block 711 slides in the arc-shaped frame 712 and drives the arc-shaped frame 712 to rotate, making the connecting rod 715 fixedly connected to the arc-shaped frame 712 drive the pushing plate 713 to reciprocate in the material guiding box 3.

[0027] Embodiment 2

[0028] Refer to Figure 4, further obtained, the material leveling mechanism 8 includes a material leveling box 801 fixedly arranged on the conveying frame 9. The discharge pipe 4 is located directly above the material leveling box 801. A frame 802 is slidably connected inside the material leveling box 801.

The arc-shaped block 711 rotatably connected to the crank 709 through the rotating shaft 710 can slide inside the arc-shaped frame 712 and drive the arc-shaped frame 712 to rotate, enabling the connecting rod 715 fixedly connected to the arc-shaped frame 712 to move reciprocally under the limitation of the limit seat 716. The connecting rod 715 drives the pushing plate 713 to move reciprocally inside the guide box 3. Under the reciprocating pushing of the pushing plate 713, the material can be intermittently discharged through the discharge pipe 4.

[0031] The material evenly falls onto the blanking mesh 803 inside the material leveling box 801. Start the vibration motor 804 to make the frame 802 drive the blanking mesh 803 to vibrate. The sliders 805 at both ends of the frame 802 slide along the slide rods 807 inside the sliding grooves 806. Under the elastic potential energy of the first spring 808 and the second spring 809, the blanking mesh 803 can vibrate up and down reciprocally, enabling the material to fall more evenly and dispersedly onto the belt conveyor 10 when discharging through the blanking mesh 803.
