In some exemplary embodiments, the lower surface of the first belt 110 moves at a greater speed than the upper surface of the conveyor belt 152.
After the grains are adsorbed on the lower surface of the first belt 110, as the movement speed of the first belt 110 is greater than the movement speed of the conveying belt 152, the adsorbed grains can drop in front of the original sucking position, so that grains at the lower layer of the original position are exposed on the upper surface, the grains pass through the next first sucking disc 116 and are sucked up, and the grains at the positions are helped to be disturbed in stacking sequences (for example, the first sucking disc 116 can suck one layer of grains each time, the upper surface of the conveying belt 152 is provided with three layers of grains in total, the grains are numbered into a first layer, a second layer and a third layer from bottom to top in sequence, the first layer is sucked up and then thrown down to the front, the second layer at the original position is exposed out, the first layer at the original position is sucked up and thrown down to the front when the first sucking disc 116 is moved down, the first layer is sucked up and then thrown down to the front when the first sucking disc 116 is passed through, the positions are different in movement speed difference and the disturbance of air flow, and therefore, the grains can not be changed in sequence by the first layer and the second layer and the first layer are not completely overlapped, the grains can not be completely overlapped, and the dust can not be removed from the front, and the first layer is not be completely overlapped, and the dust can not be completely removed, and the dust can be completely removed from the front.
In some embodiments of the grain delivery dust removing apparatus described above, the opening width of each first suction cup 116 in the front-rear direction increases sequentially from the rear to the front.
The suction force of the first suction cup 116 is gradually increased from the rear to the front so that the first suction cup 116 at the front sucks up grains at the lower layer, and under the action of different suction forces, the grains sucked up by the suction cups and attached to the lower surface of the first belt 110 have different food consumption, which is more helpful to disturb the arrangement state of grains. The displacement of the first suction cup 116 (the amount of gas sucked by the first suction cup 116 in unit time under the condition of unchanged air pressure) can also be changed by changing the size of the connection port of the first suction cup 116 and the first box 114, and a flow valve can be arranged at the connection port to adjust according to requirements.
In some exemplary embodiments, the separation distance between the first suction cups 116 increases sequentially from back to front.
Because the movement speed of the first belt 110 is constant, the distance difference that each first sucking disc 116 sucks attached grains and throws the grains forward is not large (although there is airflow disturbance), if the first sucking discs 116 are uniformly arranged at intervals, grains thrown by the first sucking discs 116 behind are easy to fall just below the adjacent first sucking discs 116 in front, so that each first sucking disc 116 sucks and throws the same group of grains in sequence, and through gradual interval arrangement, the problem can be effectively avoided, grains at different positions are sucked and thrown by each first sucking disc 116 in sequence, and grains at the lower layer are easier to suck and throw by the first sucking discs 116 in front.
As shown in connection with fig. 4 and 5, in some exemplary embodiments, the dust removing assembly further includes a second dust removing assembly 124, the second dust removing assembly 124 being located at a front side of the first dust removing, the second dust removing assembly 124 including a second driving roller 126, a second driven roller 128, a second belt 130, and a second air extracting assembly 132, the second belt 130 being disposed in a mesh shape, the mesh size of the second belt 130 being smaller than the grain particle size and larger than the dust particle size; the second driving roller 126 and the second driven roller 128 are arranged side by side and are arranged along the conveying direction of the conveying belt 152, the second belt 130 is wound on the second driving roller 126 and the second driven roller 128, the second driving roller 126 is in transmission connection with the driving device 100, the lower surface of the second belt 130 is parallel to and spaced from the upper surface of the conveying belt 152, the spacing distance between the lower surface of the second belt 130 and the upper surface of the conveying belt 152 is greater than the grain stacking thickness of the upper surface of the conveying belt 152, and the movement direction of the lower surface of the second belt 130 is the same as the movement direction of the upper surface of the conveying belt 152; the second air extraction assembly 132 is located the second belt 130 inboard, the second air extraction assembly 132 includes the second box 134, a plurality of second sucking disc 136, the second filter screen 138, the second baffle 140, each second sucking disc 136 fixed connection is at the lower surface of second box 134, the opening of each second sucking disc 136 sets up down, the lower surface of second sucking disc 136 and the medial surface subsides of second belt 130 and sliding connection, each second sucking disc 136 is along the direction of delivery interval arrangement of conveyer belt 152, the top and the second box 134 inner space intercommunication of second sucking disc 136, second baffle 140 and second filter screen 138 horizontal fixed connection are in the second box 134 is inside, second baffle 140 is located second filter screen 138 below, second filter screen 138, second baffle 140, the top surface and the bottom surface interval setting of second box 134 inboard, the front and back both ends of second baffle 140 have second breach 142, the space between second baffle 140 and the second filter screen 138 is connected with second baffle 140 space below through second breach 142, the box top is connected with the air inlet of air pump 104.
In some exemplary embodiments, the lower surface of the second belt 130 moves at a speed less than the speed of movement of the upper surface of the conveyor belt 152.
The differential motion between the second belt 130 and the conveyor belt 152 also helps to achieve the effect of differential motion between the first belt 110 and the conveyor belt 152, which helps to disturb the arrangement sequence of grains in the up-down direction and the front-back direction, and improves the dust removal effect.
In some exemplary embodiments, the difference between the lower surface movement speed of the second belt 130 and the lower surface movement speed of the first belt 110 is equal to the movement speed of the upper surface of the conveyor belt 152.
Assuming that the moving speed of the conveyor belt 152 is V and the moving speed of the first belt 110 is 1.5V, the moving speed of the second belt 130 is 0.5V, the distance of the same grain being thrown forward by the first belt 110 with respect to the conveyor belt 152 is S, the distance of the grain being thrown backward by the second belt 130 with respect to the conveyor belt 152 is S, and the total distance of the forward throws is 0 after the grains sequentially pass through the first belt 110 and the second belt 130, thereby avoiding accumulation of the grains in front of the second belt 130. Meanwhile, the differential motion between the second belt 130 and the conveyor belt 152 is also helpful to achieve the effect of differential motion between the first belt 110 and the conveyor belt 152, which is helpful to disturb the arrangement sequence of grains in the up-down direction and the front-back direction, and improve the dust removal effect.
