Description

Technical Field

[0001] The utility model relates to the technical field of coal mine excavation, in particular to an environmentally friendly coal mine excavation equipment with a dust reduction function. Background Art

[0002] Coal mining refers to the process of mining coal at the coal mine working face and opening up new mining areas. This is a complex and critical task that requires reasonable planning, scientific technology and high safety measures.

[0003] Coal mines often use tunneling machines during construction and excavation, and tunneling machines will generate some dust during operation. However, common tunneling machines do not have the function of collecting dust, which causes dust to be scattered everywhere, causing a certain impact on the environment of coal mine excavation work and failing to achieve a good working environment. However, if the dust collection function is simply added, when the dust needs to be disassembled and cleaned, good disassembly efficiency cannot be achieved, which increases the time spent by workers during the construction process and reduces the practicality of the device.

[0005] In order to achieve the above purpose, the present invention adopts the following technical solutions:

Dust suction mechanisms are provided on both the left and right sides of the excavation equipment frame. The dust suction mechanism includes two limit slots symmetrically fixedly installed on the excavation equipment frame. A collection mechanism is slidably installed in the limit slot. The collection mechanism is used to collect dust generated during the excavation process. A clamping mechanism is installed on the upper part of the limit slot. The clamping mechanism is used to realize rapid installation and disassembly of the collection mechanism.

[0007] Furthermore, the clamping mechanism includes a long screw, which is rotatably installed between two limit grooves. A threaded block is threadedly connected to the long screw, and the threaded block is slidably installed on a limit plate. The limit plate is fixedly installed between the two limit grooves. A limit shaft is fixedly connected to the threaded block, and the limit shaft passes through the through hole on the limit groove and cooperates with the limit hole on the collecting mechanism, thereby realizing the clamping of the collecting mechanism. A transmission assembly is installed on the excavation equipment frame, and the transmission assembly is used to drive the long screw to rotate.

[0008] Furthermore, the transmission assembly includes a bevel gear B, which is fixedly mounted on a long screw rod, and the bevel gear B is meshed with a bevel gear A, which is fixedly mounted on a driving rod, and the driving rod is rotatably mounted on a support plate, and the support plate is fixedly mounted on a frame of the tunneling equipment.

[0009] Furthermore, a hand wheel is fixedly connected to the upper end of the driving rod.

[0010] Furthermore, a limiting block is fixedly welded to the lower end of the limiting groove to limit the collecting mechanism.

[0011] Furthermore, the collection mechanism includes a collection box, on which a slider corresponding to the limit groove is fixedly welded, and a limit hole corresponding to the limit axis is opened on one of the sliders. A dust hopper is provided on the front side of the collection box, an induced draft fan is installed on the top of the collection box, a filter is provided below the induced draft fan, the filter is installed in the collection box, and a movable door is installed at the lower end of the collection box.

[0012] Compared with the prior art, the utility model has the following advantages:
