Referring to fig. 2 and 4, in some embodiments of the present invention, the base frame 300 includes a first mounting structure 310 and a second mounting structure 320, the two second mounting structures 320 are spaced apart, and the first mounting structure 310 is disposed between the two second mounting structures 320; the screen assembly 400 is mounted to the first mounting structure 310; the anchor bar assembly 500 is provided in two, and the two anchor bar assemblies 500 are respectively mounted to the two second mounting structures 320. The current roadway net hanging operation is usually a sheet-shaped anchor net, most anchor drilling machines only have one anchor rod assembly 500 for drilling and installing anchor rods, and before the drilling operation is carried out, the anchor net needs to be manually installed at the front end of the anchor rod assembly 500, and then holes are sequentially drilled to fix the anchor net on the inner surface of a roadway; even so, current construction mode still can only install 1m 2m anchor net, and the efficiency of construction is very low, and because traditional jumbolter only has a work arm, drilling, installation stock work efficiency is still very low after installing the anchor net, leads to the cost of labor high and the security of construction is not high.
The mesh-hanging jumbolter of the embodiment adopts the mesh-hanging assembly 400 to operate with the two anchor rod assemblies 500 simultaneously, after the mesh-hanging assembly 400 discharges the anchor mesh, the two anchor rod assemblies 500 can simultaneously perform drilling and anchor rod installation operations, namely, two positions of the anchor mesh can be simultaneously fixed, so that the construction efficiency is greatly improved; the operation of the net hanging assembly 400 does not need to be fixed by adopting manual work, thereby reducing the manual participation and improving the operation safety; the large arm 200 and drive assembly 210 arrangement also enables large-scale and multi-angle adjustment of the screen assembly 400 and bolt assembly 500, thereby expanding the use of the screen bolter of the present embodiment.
In some embodiments of the present invention, the vehicle body 100 includes a power box 110 and a cab 120, and an air compressor system, a hydraulic system, an electric control system, an engine power system, a water pump unit, etc. are installed in the power box 110, and are mainly used for providing power for traveling of the boom 200, the screen assembly 400, the anchor rod assembly 500, and the drilling machine.

In some embodiments of the present invention, as shown with reference to fig. 2 and 4, a screen assembly 400 is provided over the anchor bar assembly 500, with two second mounting structures 320 being disposed in parallel. Specifically, the anchor net in this embodiment is a coiled anchor net, so the hanging net assembly 400 needs to be disposed above the anchor rod assembly 500, so that the anchor rod assembly 500 can fix the anchor net. The two second mounting structures 320 are arranged in parallel, so that the two anchor rod assemblies 500 are also arranged in parallel, and the two anchor rod assemblies 500 are arranged in parallel, so that the positions where the two anchor rod assemblies 500 drill holes and mount anchor rods are also parallel, and the stability of anchor net fixation can be improved. Referring to fig. 4, two second mounting structures 320 are connected by a connection rod.
It is contemplated that the two second mounting structures 320 may be coupled to the base frame 300 via a lift mechanism, and thus the two second mounting structures 320 may not be parallel. If the second mounting structure 320 is connected to the base frame 300 through a lifting mechanism, the drilling of the anchor assembly 500 and the installation of the anchor may be adjusted to avoid an area unfavorable for drilling.
In some embodiments of the present invention, the projections of two second mounting structures 320 on screen assembly 400 coincide with the end and middle positions of screen assembly 400, respectively. Specifically, the working process of the mesh-hanging jumbolter of the embodiment is as follows: firstly, an anchor net roll 440 is arranged on a net hanging assembly 400, the anchor net roll 440 unreels an anchor net, and then two anchor rod assemblies 500 fix the unreeled anchor net on the surface of a roadway; the end of the anchor net is fixed at first, then the anchor net roll 440 is slowly unreeled, and the anchor rod assembly 500 sequentially performs drilling and anchor rod installation operations, so that the effect that the net is hung on the inner side wall of one cross section of the roadway at one time can be realized, and the net hanging efficiency is greatly improved as shown in fig. 1.
The width of the anchor net roll 440 in this embodiment is greater than the width of the two second mounting structures 320, specifically, the projections of the two second mounting structures 320 on the net hanging assembly 400 are respectively overlapped with the end and middle sections of the net hanging assembly 400, which illustrates the anchor rod assembly 500 mounted on the second mounting structure 320, and each time, the anchor net is fixed by fixing one side and the middle of the anchor net in the width direction. For ease of understanding, the widthwise sides of the anchor web are defined herein as a first side and a second side, respectively. With the mesh-hanging jumbolter of this embodiment, first, a first mesh-hanging operation is performed on a roadway to form a first anchor mesh surface, and after the first anchor mesh surface is completed, a first side and a middle portion of the first anchor mesh surface are fixed by two anchor rod assemblies 500. Then, after the drilling machine moves forward a small distance into the roadway, the drilling machine performs a second screening operation on the roadway to form a second anchor screen, and the first side of the second anchor screen is pressed against the second side of the first anchor screen, so that when screening is performed for the second time, the second side of the first anchor screen and the first side of the second anchor screen can be simultaneously fixed on the inner wall of the roadway by the anchor rod assembly 500 on the second mounting structure 320 where the projection of the screen assembly 400 coincides with the end part of the screen assembly 400. And the method is repeated in a circulating way, so that all nets in the roadway are hung.

The first telescopic structure 430 generally adopts an oil cylinder or an air cylinder. When the unreeling end of the anchor net roll 440 is fixed, the driving assembly 210 of the big arm 200 rotates to drive the anchor net roll 440 to unreel, so that the net hanging assembly 400 does not need to be provided with a structure for driving the first hanging rod or the second hanging rod to rotate around the axis thereof.
It is contemplated that for a drill rig that is used to screen only certain lanes, the screen assembly 400 need not be provided with the first telescoping structure 430, i.e., the screen assembly 400 can be fitted with only one size anchor rolls 440.
