[0015] The preferred embodiment of the utility model is described in detail below in combination with the drawings.

[0016] As Figure 1 The charging machine for coal mine gas extraction water glue cartridge shown in the figure, including fixed support 1, fixedly arranged on the slide rail 2 of fixed support 1 and charging mechanism and the reciprocating support 3 of charging mechanism below through the sliding connection of slide rail 2 and fixed support 1;The charging mechanism includes the feed pipe 4 of horizontal frame in the top end of fixed support 1, a plurality of discharge angle valves 5 connected with the feed pipe 4 according to fixed spacing, for injecting water glue explosive into cartridge tube;The reciprocating support 3 is provided with a plurality of groups of fixing mechanisms for placing cartridge tube according to fixed spacing, and the cartridge tube is driven to the directly below of discharge angle valve 5 by reciprocating support 2 and charges.In the specific use, the fixed support 1 is fixed to the scene by the foot screw, and the reciprocating support 3 is driven by the cylinder.

[0017] In the specific operation, the interval of the discharge angle valve 5 of the preferred embodiment is same with the interval of the fixing mechanism, and the number of the fixing mechanism is twice of the number of the discharge angle valve 5, in the specific use, the reciprocating support 2 is divided into left and right two stations, when the cartridge tube in any station is in charging state, the cartridge tube that has been charged is taken off by artificial in another station and is replaced by cartridge tube that is threaded with detonating cord but not charged.

[0018] In the charging process, in order to ensure that the liquid in the coal mine gas extraction water gel explosive column meets the height requirement and consistency requirement, a distance measuring sensor 7 for detecting the liquid level in the explosive column pipe is arranged at the discharge port of the discharge angle valve 5; when it is detected that the liquid in the coal mine gas extraction water gel explosive column reaches the preset height, the discharge angle valve is closed, and the charging is stopped.

[0019] As shown in Figure 2 Each set of the fixing mechanism includes a limiting buckle 8 arranged on the reciprocating support 3 and used for fixing the upper end of the explosive column pipe, and a cable air cylinder 9 arranged on the reciprocating support 3 and used for fixing the bottom end of the explosive column pipe.

[0020] The axial one end of the feeding pipe 4 is connected with the explosive storage tank or hopper through the feeding pipe and the water gel explosive delivery pump, the axial other end of the feeding pipe 4 is connected with the explosive storage tank or hopper through the special backflow device, and the special backflow device includes a backflow pipe and a backflow valve 6 connected with the backflow pipe and the feeding pipe.

[0021] Since the discharging process is intermittent in the actual operation of the charging machine, that is, from when the discharge angle valve 5 is automatically closed after the automatic feeding is completed to when the next discharge angle valve 5 is opened; and in the continuous production of water gel explosives, the discharging interval is short, but if it is not controlled, it will cause the delivery pipeline and the explosive delivery pump to be over-pressured, causing safety problems; if the explosive delivery pump is frequently started and stopped, the equipment is prone to wear and tear; at the same time, since the explosive has a certain compression capacity, if the explosive delivery pressure is controlled by starting and stopping the explosive delivery pump, the explosive flow will be small in a short time after the explosive delivery pump is started at the beginning of each discharging, which will affect the filling speed. Therefore, through the special backflow device, when all the discharge angle valves 5 are closed, the backflow valve 6 is opened, and the feeding pipe 4 returns the explosive to the explosive storage tank or hopper through the backflow pipe. The overall pressure of the explosive delivery system is controlled, the equipment wear and tear is reduced, the discharging pressure is maintained, and continuous explosive filling is facilitated.

[0022] Further, the preferred embodiment also has a interlocking protection mechanism: when any distance measuring sensor detects that the liquid in the explosive column reaches the preset liquid level, the corresponding discharge angle valve 5 automatically ends the feeding. After all the discharge angle valves 5 end the feeding, the automatic feeding is completed, and the next automatic feeding step is prepared. At the same time, in order to reduce the equipment wear and tear caused by the start and stop of the explosive delivery pump, under any circumstances, when the discharge angle valves 5 are all closed, the backflow valves will be immediately opened, so that the explosive is returned to the storage tank or hopper, so as to reduce the related pressure of the explosive delivery pump and the explosive delivery pipeline, and prevent safety accidents.

[0023] The charging machine of the preferred embodiment realizes automation of the charging process through electric control elements such as the control cabinet, the pneumatic cabinet, the power distribution cabinet, etc. The control cabinet is arranged outside the explosion-proof area, and connects various input and output signals through wires. The main input signals connected to the control cabinet include the distance measuring sensor and the field explosion-proof control button box, and the main output signals include the electromagnetic valve of the pneumatic cabinet. The pneumatic cabinet is arranged outside the explosion-proof area, and is connected to the discharge angle valve 5, the backflow valve and the cylinder of the reciprocating support 3 through the compressed air pipe (PU pipe).

[0024] In the production of explosives, if the control cabinet, the pneumatic cabinet, the power distribution cabinet, etc. are arranged in the same space as the charging machine, the equipment cost will be greatly increased, and a large space in the explosion-proof workshop will be occupied. Therefore, in the preferred embodiment, the control cabinet (the control cabinet and the power distribution cabinet are the same cabinet) and the pneumatic cabinet are arranged outside the explosion-proof area, which can significantly improve the economy and safety of the equipment.

[0025] The working process and principle of the charging machine: assuming that the left work station of the reciprocating support 2 is located directly below the discharge angle valve in the initial state, the working process of the charging machine of the preferred embodiment is as follows: a charge column pipe with a detonating cord but without charge is placed on the right work station; the equipment is started to make the reciprocating support 2 drive the charge column pipe on the right work station to move to below the discharge angle valve 5, and all the discharge angle valves 5 are opened to charge the charge column pipe, while a charge column pipe with a detonating cord but without charge is placed on the left work station again; during the charging process, the distance measuring sensor 7 is used to detect the liquid level of the charge column pipe in real time, and when the liquid level of all the charge column pipes reaches the preset height, the equipment is started again to make the reciprocating support drive the charge column pipe on the left work station to move to below the discharge angle valve 5, and all the discharge angle valves 5 are opened to charge the charge column pipe, while the charge column pipe on the right work station which has been charged is removed and replaced with a charge column pipe with a detonating cord but without charge; the above operation is repeated to realize the semi-automatic charging process.

[0026] The above-described embodiments are only used to describe the preferred embodiments of the present application, and do not limit the scope of the present application. Without departing from the design spirit of the present application, various modifications and improvements to the technical solutions of the present application made by those skilled in the art shall fall within the protection scope determined by the claims of the present application.
