[0033] Please refer to Figures 1 to 4 As shown, the present utility model provides a mine portable spraying accelerator adding device, which includes a backpack-type housing 1, a replaceable bottled accelerator 2, a pumping assembly and an atomizing assembly.
[0034] The backpack-type housing 1 includes a housing main body and straps (not shown in the figure) symmetrically arranged on one side of the housing main body, and is adapted to be carried on the back of a user.
[0035] A quick-setting agent bottle base 7 for fixedly installing the bottled quick-setting agent 2 is arranged at the bottom of the backpack-type housing 1.
[0036] Please refer to Figure 1 As shown, when installing the bottled quick-setting agent 2, the top hard plastic pipe of the quick-setting agent bottle base 7 pushes the elastic plug on the opening of the bottled quick-setting agent 2 into the interior of the bottled quick-setting agent 2, and the end of the hard plastic pipe is connected to a hose 8, and the liquid connection between the bottled quick-setting agent 2 and the pumping assembly is realized through the connecting hose 8.
[0037] A plurality of groups of plastic protection rings 3 are also arranged on the backpack-type housing 1; and the plastic protection rings 3 are regularly arranged from top to bottom. The plastic protection rings 3 surround the bottled quick-setting agent 2 to protect and position the bottled quick-setting agent 2 to keep the bottled quick-setting agent 2 stable.
[0038] Please refer to Figure 1 and Figure 2 As shown, the bottled quick-setting agent 2 is detachably installed on the backpack-type housing 1 and is arranged with the opening facing downwards; an elastic plug is arranged on the opening of the bottled quick-setting agent 2, which includes a bottle cap plug 13 and a spring 14 arranged at the end of the bottle cap plug 13. The bottle cap plug 13 and the spring 14 prevent the liquid from flowing out during the flipping and replacement process of the bottled quick-setting agent 2.
[0039] The structure of the bottled quick-setting agent 2 is designed with the opening facing downwards. Based on the action of gravity, this design enables the quick-setting agent liquid in the bottle to generate a certain pressure by means of gravity when flowing towards the pump 4. This design effectively improves the working efficiency of the pump 4.
[0040] Please refer to Figure 1 As shown, the pumping assembly is arranged at the bottom of the backpack-type housing 1 and is connected to the opening of the bottled quick-setting agent 2 through a connecting hose 8 for piping connection to pump the quick-setting agent into the atomizing assembly.
[0041] The pumping assembly includes a pump 4, a controller 6 for controlling the flow rate of the pump 4, and a detachable battery 5 for powering the pump 4.
[0042] The controller 6 can be hung on the waist belt of the shotcreting operator, and the shotcreting operator controls the flow rate of the quick-setting agent. The pump 4 uses a detachable battery 5 as the energy source, can maintain a high-efficiency pumping operation for a long time, and is more suitable for shotcreting operations in roadways compared to manual mechanical pressurized water pumps and external power source water pumps. Moreover, the pumping speed can be adjusted by the controller 6, making the operation more flexible.
[0043] The pump 4 presses the quick-setting agent into the atomizer nozzle 11 through a pumping hose 9 and a hose differential device 10.
[0044] Please refer to Figure 3 and Figure 4 As shown, the atomizing assembly is connected to the pumping assembly through a pumping hose 9 and a hose differential device 10, and includes a nozzle collar 12 and a plurality of atomizer nozzles 11 arranged on the nozzle collar 12.

[0046] In some embodiments, the spraying direction of the atomizer nozzle 11 forms an angle of 30° with the central axis of the nozzle of the shotcrete machine sleeved by the nozzle collar, that is, the direction of the atomized quick-setting agent sprayed by the atomizer nozzle 11 is in an inclined state, so that it can be fully fused with the cement sprayed by the nozzle of the shotcrete machine.
[0047] The atomizer nozzle 11 is circumferentially arranged on the nozzle collar 12 by a nozzle hook 15.
[0048] The nozzle collar 12 adopts a live-opening design with an adjustable orifice size for indicating nozzles of different sizes of the shotcrete machine.
[0049] The nozzle ferrule 12 is made of cortical material with high friction. The atomizer nozzle 11 is hung tightly on the nozzle ferrule 12 by the nozzle hook 15, and then the nozzle ferrule 12 is fastened to the nozzle of the cement spraying machine with a buckle.
[0050] The atomizer nozzle 11 is detachable. When the total working time is relatively long, it is easy for cement powder to adhere, resulting in the phenomenon that the atomizer nozzle 11 is not easy to discharge liquid. At this time, the construction operation can be continued by replacing a new nozzle.
[0051] It should be noted that Figure 3 The solution of the structure in which the three atomizer nozzles 11 are arranged around the nozzle ferrule 12 is only an exemplary illustration of the above atomization component structure of the present invention. Those skilled in the art can adopt the structure in which other numbers of atomizer nozzles 11 are arranged around for substitution, and all are within the protection scope of the atomization component of the present invention.
[0052] The working and installation methods of the mine portable spraying accelerator adding device provided by the present invention are as follows:
[0053] Step 1: Install the bottled accelerator 2 on the accelerator bottle base 7 at the bottom of the backpack-type housing 1; the hard plastic pipe at the top of the accelerator bottle base 7 pushes the elastic sealing member on the opening of the bottled accelerator 2 into the bottled accelerator 2, and realizes the liquid connection between the bottled accelerator 2 and the pumping assembly through the connecting hose 8. And install the plastic protection ring 3, the pumping assembly and the atomization assembly to realize the overall installation of the mine portable spraying accelerator adding device.
[0054] Step 2: During the spraying operation, the spraying staff carry the backpack-type housing 1 on their backs and put the atomizer nozzle 11 on the nozzle of the cement spraying with the nozzle ferrule 12. Turn on the portable pump 4 to spray, and then the feeding staff turn on the spraying machine to perform the spraying operation, so that the accelerator sprayed by the atomizer nozzle 11 is fused with the cement sprayed by the cement spraying nozzle to achieve the purpose of uniform mixing. Both the bottled accelerator 2 and the atomizer nozzle 11 can be quickly replaced during the working process.
[0055] Step 3: After the spraying operation is completed, the mine portable spraying accelerator adding device can be disassembled as a whole or in part for recycling and storage.
