TECHNICAL FIELD
[0001] The utility model relates to material guide groove dust falling auxiliary device technical field especially, relates to a wave resistance combined formula dust falling material guide groove. BACKGROUND
[0002] In the link of often carrying out bulk material transportation and conveying in electric power, metallurgy, mine, building material etc., belt conveyor is indispensable equipment, and the material guide groove of belt conveyor is important facility of preventing spilling and dust overflow of receiving material on the conveyor. But when bulk material falls on the belt from the previous link, the induced wind caused by the dust raised by high-speed falling of bulk material and bulk material causes dust to spread around, and most of the dust forms a through wind in the inside of the material guide groove along the conveying direction of the belt conveyor, and finally spills out from the front end outlet of the material guide groove. In addition, a small part of dust spills out from the gap between the lower side of the material guide groove and the belt.

[0003] Therefore, there are various ways for dust removal of the material guide groove at present, such as setting a special dust collector on the material guide groove, which aims to form negative pressure in the material guide groove and remove all dust. But the dust collector has high energy consumption and poor effect, especially after a long time, the dust collector is blocked, and the dust removal efficiency is obviously reduced, and in addition, the investment and operation and maintenance cost of the dust collector is relatively high, especially the later maintenance is difficult. In addition, there is a non-powered dust removal material guide groove, which is to set a pressure relief valve, a backflow pipe or increase the internal space of the material guide groove in the material falling section of the material guide groove, so as to reduce the wind speed. In addition, an anti-overflow apron is arranged on the side, but it only alleviates and reduces the induced wind speed, and the pressure relief valve and the backflow pipe can only be arranged in the material falling section, which has the maximum induced wind. Such setting can eliminate and reduce a part of the induced wind, but the position of eliminating the induced wind is too concentrated, and the induced wind speed cannot be reduced to the maximum, and the dust removal effect is limited. In addition, although the side of the material guide groove has an anti-overflow apron, dust still spills out from the gap of the anti-overflow apron.
