As used herein, the term "and/or" includes any and all combinations of one or more of the associated listed items.
Referring to fig. 1 to 3, the discharging, dust suppressing and guiding device of the present invention is installed in a head hopper 4 of a conveyor 6, and includes a material guiding structure 1, a first adjusting mechanism 2 and a second adjusting mechanism 3, wherein: the material guiding structure 1 is provided with a first material guiding section A and a second material guiding section B which are sequentially arranged along the material flowing direction, and the first material guiding section A is smoothly connected with the second material guiding section B; the first adjusting mechanism 2 is connected above the material guiding structure 1, and the first adjusting mechanism 2 is used for adjusting and fixing the distance LQ between the feeding port of the material guiding structure 1 and the highest contact point Q of the material conveyed by the conveyor 6; the second adjusting mechanism 3 is connected to a side of the material guiding structure 1 opposite to the conveyor 6, and the second adjusting mechanism 3 is used for adjusting and fixing an impact pressure angle X of the material guiding structure 1, which bears material impact.
The unloading dust suppression flow guide device can reduce the impact force of materials when the materials are transferred between the belt conveyors, so that the materials are transferred more stably, the equipment abrasion is reduced, the material splashing and dust escape caused by impact collision of the materials are reduced, and the environmental pollution is reduced. In the material conveying process, after the material is separated from the previous conveyor 6, the material can smoothly slide to the next conveyor 6 under the guidance of the material guiding structure 1, the first material guiding section A smoothly guides and changes the moving direction of the material, and the second material guiding section B smoothly conveys the material to the next conveyor 6, so that the material is transferred between the conveyors without impact.
Referring to fig. 4 and 5, the first adjusting mechanism 2 can make materials with different conveying speeds be guided completely by the material guiding structure 1. When the material is thrown out by the conveyor 6 in a flat throw motion, the material moves along a parabolic track and impacts the material guiding structure 1, the material contacts the material guiding structure 1 to generate a highest contact point Q, and when the conveying speed of the material is slow or the material guiding structure 1 is too far away from the material, the highest contact point Q is lower, so that the distance LQ between the inlet of the material guiding structure 1 and the highest contact point Q is too long, and the effect of the material guiding structure 1 in guiding the material is poor. The first adjusting mechanism 2 can adjust and fix the distance LQ between the feeding port of the material guiding structure 1 and the highest contact point Q of the material conveyed by the conveyor 6, so as to fully utilize the whole length of the material guiding structure 1 and adapt to different material speeds and conveying conditions. The first adjusting mechanism 2 can make the material guiding structure 1 generate movement in the direction F or the direction opposite to the direction F, so as to change the position of the highest contact point of the material and the material guiding structure 1. For example, when the first adjusting mechanism 2 moves the material guiding structure 1 along the direction F, the highest contact point Q moves upward to become the adjusted highest contact point T, and the distance between the inlet of the material guiding structure 1 and the adjusted highest contact point T is shortened to LT, so as to increase the distance that the material guiding structure 1 can effectively guide the material, thereby effectively improving the material guiding effect of the material guiding structure 1.
Referring to fig. 6 and 7, the second adjusting mechanism 3 can enable materials with different conveying speeds to smoothly enter the material guiding structure 1. When the material moves and flows into the material guiding structure 1, the material contacts with the material guiding structure 1 and generates an impact pressure angle X, and when the material conveying speed is increased or the pitch angle of the material guiding structure 1 is poorly matched with the material trajectory, the angle of the impact pressure angle X is large, so that the effect of the material guiding structure 1 on guiding the material is poor. The second adjusting mechanism 3 can adjust and fix the impact pressure angle of the material guiding structure for bearing the impact of the material, so that the pitch angle of the material guiding structure 1 is matched with the motion track of the material, and the material guiding structure is suitable for different material speeds and conveying working conditions. The second adjusting mechanism 3 can make the material guiding structure 1 generate a rotation motion in the direction E or the direction opposite to the direction E, so as to change the pitch angle of the material guiding structure 1. For example, when the second adjusting mechanism 3 makes the material guiding structure 1 move along the direction E, the depression angle of the material guiding structure 1 is increased, so that the impact pressure angle is decreased to become a smaller adjusted impact pressure angle Y, so that the material can enter the material guiding structure 1 more smoothly, the guiding effect of the material guiding structure 1 on the material is effectively improved, and the impact of the material when contacting with the material guiding structure 1 is reduced.
Specifically, the material guiding structure 1 is a long-trough structure, the first material guiding section a is an arc structure, the second material guiding section B is a straight structure, and the first material guiding section a and the second material guiding section B are tangent and smoothly connected, so that the trough of the material guiding structure 1 stably guides the flowing direction of the material. The material guiding structure 1 is suspended on the first adjusting mechanism 2, so that the first adjusting mechanism 2 can adjust the material guiding structure 1, and the first adjusting mechanism 2 and the second adjusting mechanism 3 jointly fix the material guiding structure 1. The first adjusting mechanism 2 and the second adjusting mechanism 3 can be adjusted by manual operation of an operator, and can also be adjusted automatically by matching with automatic control equipment by utilizing electric equipment or hydraulic equipment.

The material flow channel 11 is used for containing and guiding flowing material, the width W1 of the inlet of the material flow channel 11 is larger than the width W2 of the outlet of the material flow channel 11, so that the material can enter the material flow channel 11 more easily, the depth D1 of the inlet of the material flow channel 11 is smaller than the depth D2 of the outlet of the material flow channel 11, and the material can be gradually gathered without overflowing by matching with the increasingly narrower width W of the material flow channel 11. Specifically, the width W and the depth D of the material flow channel 11 are gradually changed in a transitional manner along the material flow direction, so that collision and splashing of materials caused by shape mutation are reduced.

Specifically, the cross-sectional shape of the material flow channel 11 gradually changes from rectangular or trapezoidal to semicircular along the material flow direction, so as to guide the materials to gradually gather in the material flow channel 11.
