Description

Technical Field

[0001] The present application relates to the field of mining technology, and in particular to an automatic dust prevention device for a branch chute of a long-distance chute system in a mine. Background Art

[0002] With the depletion of some high-quality mining resources, in order to give full play to the advantages of currently exploitable mining resources and improve the production capacity of high-quality mines, the current mines are facing a situation of simultaneous mining in multiple middle sections and multiple sections. In order to improve the utilization rate of a single chute, increase the number of operating points served by a single chute as much as possible, reduce frequent transit transportation, and reduce production costs, long-distance chutes are used more and more frequently, and the methods of use are similar. After the construction of the main chute, branch chutes are constructed on the sections to connect to the main chute position, and are connected by grooving to form conditions for the simultaneous use of multiple sections above and below. However, this method also faces many problems. Among them, the more difficult one is the problem of dust cross-flow and diffusion pollution to other working surfaces when the upper or lower branch chutes discharge ore (slag), which is also the key problem that needs to be solved by the current long-distance branch chutes. Utility Model Content

[0003] In order to solve or partially solve the problems existing in the related art, the present application provides an automatic dust prevention device for a branch chute of a long-distance mine chute system.

[0005] Automatic rolling shutter door, fixed signal sensing device, chute connection, branch chute, screen, inverted wedge hanging pile, mobile signal sensing device;

[0006] Among them, the chute connecting channel runs through the chute shaft and is located between the upper end and the lower end of the chute shaft. A groove is cut at the connection between the chute connecting channel and the chute shaft to form a branch chute. A screen is arranged on the branch chute. The screen is connected by an inverted wedge hanging pile. The inverted wedge hanging pile is arranged on the inner wall of the chute connecting channel. A fixed signal sensing device and an automatic rolling door are arranged in the chute connecting channel. The automatic rolling door is arranged between the branch chute and the fixed signal sensing device. The mobile signal sensing device is arranged on the scraper.

[0007] Optionally, in some embodiments of the first aspect, an automatic rolling door is installed three meters away from the branch chute.

[0008] Optionally, in some embodiments of the first aspect, the fixed signal sensing device is arranged ten meters away from the installation of the automatic rolling door, so that when the shovel loader passes through the fixed signal sensing device when discharging ore / slag, there is sufficient time for the automatic rolling door to open automatically.

[0009] Optionally, in some embodiments of the first aspect, the branch chute is arranged at an angle.

[0010] Optionally, in some embodiments of the first aspect, the screen is arranged at an angle.

[0011] The technical solution provided by this application may have the following beneficial effects:

[0012] The present application installs a mobile signal sensing device on the shovel loader. At the same time, the fixed signal sensing device is adapted to the mobile signal sensing device. When the mobile signal sensing device passes through the fixed signal sensing device, the control signal on the fixed signal sensing device is triggered. The control signal controls the automatic rolling door to open or close. In this way, when the shovel loader passes through the fixed signal sensing device when discharging ore (slag), the automatic rolling door is automatically opened, and the conditions for discharging ore (slag) are met; after the shovel loader completes discharging ore (slag), the fixed signal sensing device is triggered again when passing through the fixed signal sensing device, and the rolling door is automatically closed, so that the chute connecting channel and the chute shaft are connected only when the shovel loader is running, and are closed at other times.
