[0002] Blasting charge loading is an important link in blasting engineering, and its purpose is to achieve the expected blasting effect by reasonably configuring and using explosives. Drilling blasting is a commonly used technology for blasting charge loading and is widely used in fields such as water conservancy and hydropower, mines, and transportation. Specifically, first, a blast hole with a required depth for charge loading is drilled, explosives are placed into the blast hole, and then the blast hole is plugged. During the blasting construction process, plugging the blast hole can increase the pressure of the detonation gas acting on the hole wall and extend the time of pressure action, thereby greatly improving the degree of rock fracturing and throwing distance, and thus improving the blasting effect.

Detailed implementation manners

[0025] To make the objectives, technical solutions and advantages of the embodiments of the present application clearer, the following clearly and completely describes the technical solutions in the embodiments of the present application. Obviously, the described embodiments are some but not all of the embodiments of the present application. Based on the embodiments in the present application, all other embodiments obtained by those of ordinary skill in the art without creative efforts also belong to the scope of protection of the present application.

[0026] Refer to Figures 1 to 3 , the present application provides a blast hole plugging device for blasting charge, including:

[0027] Cyclone separator body 100, a first pipe 101 and a second pipe 102 are respectively connected to the dust-containing air inlet and the clean air outlet of the cyclone separator body 100, and a draft fan 1021 is connected to one end of the second pipe 102 far away from the cyclone separator body 100; wherein, the cyclone separator body 100 is used for cyclone separating the mixture of rock powder and air entering from its dust-containing air inlet, and the separated air is discharged through its clean air outlet, and its separation principle is to rely on the rotational motion caused by the tangential introduction of the air flow to separate the solid particles (rock powder) with larger inertial centrifugal force to the outer wall surface. The specifications and models of the cyclone separator body 100 can be set according to actual needs, and the present application does not make specific limitations on it here.

[0028] Dust collection box 200, the dust collection box 200 is connected to the ash hopper of the cyclone separator body 100 and a dust discharge pipe 103 is vertically connected to its bottom, and a dust discharge valve 1031 is arranged on the dust discharge pipe 103; wherein, the dust collection box 200 is used for storing the rock powder after air separation. The specifications and models of the dust discharge valve 1031 can be set according to actual needs, and the present application does not make specific limitations on it here.

[0029] Dust blowing pipe 300, both ends of the dust blowing pipe 300 are respectively connected to a blower 301 and a third pipe 302, and its pipe body is vertically connected to the bottom end of the dust discharge pipe 103. Wherein, the positive pressure generated by the blower 301 blows the rock powder flowing into the dust blowing pipe 300 from the dust collection box 200 and the dust discharge pipe 103 into the blast hole filled with explosive through the third pipe 302, avoiding the situation of manually filling the rock powder drilled by a spade into the blast hole, saving manpower, and thus improving the efficiency of blast hole stemming.

[0030] The blast hole plugging device provided by the present application places one end of the first pipe 101 away from the cyclone separator body 100 at the rock powder accumulation site, turns on the induced draft fan 1021, and sucks the mixture of rock powder and air into the cyclone separator body 100 through the first pipe 101 and the dust-containing air inlet of the cyclone separator body 100 in sequence by the induced draft fan 1021. The cyclone separator body 100 performs cyclone separation on the air and rock powder. The separated air is discharged through the clean air outlet of the cyclone separator body 100, the second pipe 102, and the air outlet of the induced draft fan 1021 in sequence, while the separated rock powder is discharged into the dust collection box 200 through the ash hopper of the cyclone separator body 100, thereby realizing the storage of rock powder by the dust collection box 200. In addition, after the rock powder in the blast hole is completely sucked out, explosives are loaded into the blast hole. One end of the third pipe 302 away from the dust blowing pipe 300 is placed into the blast hole, the ash discharge valve 1031 and the blower 301 are turned on, and the rock powder stored in the dust collection box 200 enters the dust blowing pipe 300 through the dust discharge pipe 103 in sequence. The blower 301 blows the rock powder entering the dust blowing pipe 300 into the blast hole filled with explosives through the dust blowing pipe 300 and the third pipe 302 in sequence, thereby realizing the plugging of the blast hole filled with explosives. The present application realizes the suction of rock powder through the negative pressure generated by the induced draft fan 1021, and then discharges the rock powder sucked into the dust collection box 200 into the blast hole filled with explosives through the positive pressure generated by the blower 301, realizing the automatic suction and discharge of rock powder, thereby improving the efficiency of blast hole plugging.

[0031] In some embodiments, referring to Figure 2 , in the present application, the dust collection box 200 is arranged on the support frame 400, and the height of the support frame 400 is greater than the sum of the length of the dust discharge pipe 103 and the diameter of the dust blowing pipe 300.

[0032] In the above embodiments, the dust collection box 200 is supported by the support frame 400, thereby realizing the stability of the support of the cyclone separator body 100 on the dust collection box 200. The height of the support frame 400 being greater than the sum of the length of the dust discharge pipe 103 and the diameter of the third pipe 302 can ensure that while the support frame 400 supports the dust collection box 200 and the cyclone separator body 100, it does not affect the installation of the dust discharge pipe 103 and the dust blowing pipe 300, ensuring that the blast hole plugging process can proceed normally.

[0033] In some embodiments, referring to 1 and Figure 2 , in the present application, both the length and width of the dust collection box 200 are greater than the outer diameter of the cyclone separator body 100. In this way, the cyclone separator body 100 can be stably supported by the dust collection box 200, ensuring the stability of the cyclone separator body 100 during operation, and enabling the dust collection box 200 to have sufficient space to store rock powder, that is, the dust collection box 200 can store the rock powder in the blast hole and the rock powder accumulated around the blast hole during the drilling process.

[0034] In some embodiments, both the first pipeline 101 and the third pipeline 302 in the present application are corrugated hoses. Among them, the corrugated hose absorbs vibration energy, can play roles such as vibration reduction and noise elimination, and has advantages such as good flexibility, light weight, corrosion resistance, fatigue resistance, and resistance to high and low temperatures. Therefore, during the process of rock powder absorption and discharge, the first pipeline 101 and the third pipeline 302 made of corrugated hoses are convenient to be pulled, bent, etc. according to the actual usage situation, making the process of rock powder absorption and discharge more convenient. In addition, the lengths of the first pipeline 101 and the third pipeline 302 can be set according to actual needs, and the present application does not make specific limitations on this.

[0035] In some embodiments, referring to Figure 1 and Figure 2 , the bottom of the ash hopper of the cyclone separator body 100 in the present application is communicated with the top of the dust collection box 200. Among them, the bottom of the ash hopper of the cyclone separator body 100 is communicated with the top of the dust collection box 200 through the fourth pipeline 600. In order to prevent the rock powder collected in the dust collection box 200 from entering the cyclone separator body 100 again, a check valve 601 is provided on the fourth pipeline 600, thereby reducing the separation pressure of the cyclone separator body 100. In addition, since the ash hopper of the cyclone separator body 100 is arranged at the bottom of the cyclone separator body 100, and the bottom of the ash hopper of the cyclone separator body 100 is communicated with the top of the dust collection box 200, the rock powder can quickly enter the dust collection box 200 under the action of gravity, thereby improving the collection efficiency of the rock powder.

[0036] In some embodiments, referring to Figure 1 and Figure 2 , a dust collection hood 1011 is provided at one end of the first pipeline 101 away from the cyclone separator body 100.

[0037] In the above-mentioned embodiments, the setting of the dust collection hood 1011 increases the contact area between the dust collection hood 1011 and the rock powder accumulation point, surrounds the rock powder as much as possible, thereby improving the capture rate of the rock powder and making the inhalation efficiency of the rock powder higher.

[0038] In some embodiments, referring to Figure 2 and Figure 3, a PLC controller 201 is provided on the outer wall of the dust collection box 200 in this application, and a material level sensor 202 is provided therein; wherein, the PLC controller 201 is a programmable logic controller, which is a digital operation electronic system specially designed for application in industrial environments. It uses a programmable memory to store instructions for performing operations such as logical operations, sequential control, timing, counting, and arithmetic operations inside it, and controls various types of mechanical equipment or production processes through digital or analog inputs and outputs. The specifications and models of the PLC controller 201 and the material level sensor 202 can be set according to actual needs. Therefore, this application does not make specific limitations on them here.

[0039] Specifically, the ash discharge valve 1031 is an electric ash discharge valve, and the induced draft fan 1021, the blower 301, the material level sensor 202, and the ash discharge valve 1031 are all electrically connected to the PLC controller 201.

[0040] In the above embodiment, the maximum material level in the dust collection box 200 that can collect rock powder is a preset material level threshold (specifically depending on the size of the dust collection box 200, which is not specifically limited here). The material level sensor 202 detects the material level of the rock powder collected in the dust collection box 200 and transmits the detected signal to the PLC controller 201. The PLC controller 201 judges the size of the material level value detected by the material level sensor 202 and the preset material level threshold. When the material level value is close to the preset material level threshold, the PLC controller 201 opens the ash discharge valve 1031, and the rock powder stored in the dust collection box 200 enters the dust blowing pipe 300 through the dust discharge pipe 103 in sequence. The blower 301 blows the rock powder entering the dust blowing pipe 300 into the blast holes filled with explosives through the dust blowing pipe 300 and the third pipe 302 in sequence, so as to realize the stemming of the blast holes filled with explosives. In addition, during the whole process of rock powder inhalation and discharge, the PLC controller 201 controls the on / off of the induced draft fan 1021 and the blower 301.

[0041] In some embodiments, referring to Figure 2 , the blast hole stemming device for blasting charges in this application further includes a mobile base 500; specifically, the induced draft fan 1021, the blower 301, and the support frame 400 are all arranged on the upper surface of the mobile base 500. The bottom of the mobile base 500 is provided with universal wheels 501 and a push handle 502 is provided thereon.

[0042] In the above embodiments, the moving base 500 is used to support the induced draft fan 1021, the blower 301 and the support frame 400, so that the structural components involved in the inhalation and discharge of rock powder are all placed on the moving base 500, which is convenient for integrating each component. By pushing or pulling the push handle, the moving base 500 drives the structural components involved in the inhalation and discharge of rock powder arranged thereon through the universal wheels 501 at its bottom, so that they can be quickly moved to the working position, thereby improving the convenience and working efficiency of the rock powder inhalation and discharge process.

[0043] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present application, rather than to limit them; although the present application has been described in detail with reference to the foregoing embodiments, those of ordinary skill in the art should understand that they can still modify the technical solutions recorded in the foregoing embodiments, or perform equivalent replacements on some or all of the technical features; and these modifications or replacements do not make the essence of the corresponding technical solutions deviate from the scope of the technical solutions of the embodiments of the present application.
