FIG. 5 is a drawing showing a guide rod (160) of an automatic sand injection device (100) according to an embodiment of the invention.

[0033] Referring to FIGS. 1 to 5, the sand automatic injection device (100) has a sand supply tank (110), a film supply unit (120), a cutting device (130), a guide rod support device (140), a sand injection device (150), and a guide rod (160) as main components, and may further be equipped with an up-and-down movement device (170), a sealing device (180), and an external force providing part (190).

[0034] The sand supply tank (110) has a sand input section formed at the top to receive sand, and a supply hole is provided on the bottom surface to supply sand to the sand injection device (150).

[0035] Meanwhile, individual units corresponding to a film supply unit (120), a cutting device (130), a guide rod support device (140), a sand injection device (150), a guide rod (160), an up-and-down movement device (170), a sealing device (180), and an external force providing part (190) from a single sand supply tank (110) may be provided in multiple numbers, i.e., four units in pairs in the drawing, as shown in FIG. 1, and this is just one example and the number can be varied.

[0036] The film supply unit (120) is formed with two or more pulleys to supply film-type sand bags to the cutting device (130), thereby allowing film-type sand bags supplied from the outside to be supplied to the cutting device (130).

[0037] As shown in FIG. 2, the cutting device (130) includes a cutting surface (131) and a horizontal moving device (132). After the opening of the film-type sand bag is opened by the spire structure of the guide rod support device (140), the cutting surface (131) moves to a cutting position according to the operation of the horizontal moving device (132) to cut the upper part of the sand bag placed at that position. At this time, the cutting surface (131) connected to the horizontal moving device (132) cuts the upper part of the sand bag moved to that position, thereby forming an opening that allows sand injection.

[0038] As shown in FIG. 3, the guide rod support device (140) is formed spaced apart from the bottom of the cutting device (130) to support the upper area of ​​the guide rod, so that even if the film-type sand bag moves downward by the vertical movement device (170), it can withstand the weight of the guide rod (160) and perform the role of stably supporting it.

[0039] More specifically, the guide rod support device (140) can be formed between the cutting device (130) and the guide rod (160) in a vertical direction to guide the film-type sand bag cut by the cutting device (130) in a vertical direction and to support the guide rod (160), and a push bar (141) and a horizontal moving member (142) are formed so that the position of the horizontal moving member (142), which is formed as a cylinder relative to the push bar (141), can be fixed according to control by the control unit (100a).

[0040] The guide rod (160) is stably supported by the guide rod support device (140) and can be formed to a preset length so that it can move up and down while the film-type sand bag is inserted into the outer surface, and the upper end is formed in a spire shape to open the lower end of the film-type sand bag, and hemispherical recessed areas can be formed on both sides of the lower end of the spire shape to prevent the film-type sand bag from falling out.

[0041] A cutting device forming area (130a) is provided at the bottom of the engraved area of ​​the guide rod (160), so that the cutting device (130) can be connected to cut the upper surface of the film-type sand bag that has come down along the guide rod (160).

[0043] Meanwhile, referring to FIGS. 1 and 4, the sand injection device (150) includes a metering device (151), a metering opening / closing unit (152), and a sand metering injection unit (153), thereby allowing the sand supplied to the sand supply tank (110) to be supplied obliquely to the opening surface of the upper part of a film-type sand bag located at the top of a guide rod (160) formed as a set spaced apart in front on the sand automatic injection device (100).

[0044] To this end, the measuring device (151) of the sand injection device (150) may be formed as an electronic opening / closing unit or a mechanical opening / closing unit formed with a cylinder and a partition to perform the function of providing a predetermined amount of sand to a measuring opening / closing unit (152) formed at the lower end outlet of the same measuring unit through the upper inlet of the measuring unit of the sand injection device (150) formed with the measuring device (151) of the sand injection device (150) under the control of the control unit (100a).

[0045] Meanwhile, in another embodiment of the present invention, the metering device (151) may additionally be equipped with a sensor module having an infrared emitting unit and a light receiving unit to detect the amount of sand filled in the lower direction and provide it to the control unit (100a).

[0046] Additionally, the quantitative opening / closing section (152) of the sand injection device (150) is a mechanical valve device provided at the bottom of the quantitative device (151), and maintains a closed state until a predetermined amount of sand is filled into the quantitative device (151) through the upper inlet. At this time, a sensor module is provided inside and outside the quantitative opening / closing section (152) of the sand injection device (150) to detect whether the amount of sand filled inside has reached a preset standard value, and a signal is transmitted to the control unit (100a). Accordingly, the control unit (100a) drives the quantitative opening / closing section (152) to perform an opening operation during the opening / closing operation, thereby supplying the sand inside the quantitative device (151) to a film-type sand bag through the injection section inlet (154).

[0047] More specifically, the quantitative opening / closing section (152) may be a mechanical valve formed such that a cylinder formed parallel to and spaced apart from the inlet section in a vertical direction, and a horizontal section connected to a rotating shaft connected to the lower end of the cylinder, and the horizontal section blocking the inlet moves upward by the control unit (100a), causing the horizontal section to be inclined downward at a preset angle along the rotating shaft formed at the end of the cylinder, thereby enabling opening, and closing can be performed by the opposite action. Meanwhile, in another embodiment of the present invention, the quantitative opening / closing section (152) may be modified and formed as an electronic opening / closing valve.

[0048] The sand injection device (150) is provided with an injection inlet (154) in the shape of a funnel with an inverted triangular cross-section at the top, which is formed in a vertical direction so that it can receive sand discharged from the metering device (151) when the metering opening / closing unit (152) is opened. The bottom of the injection inlet (154) is connected to a sand injection pipe that is inclined at a preset angle (e.g., 30 to 60 degrees) relative to the horizontal direction, and the sand moves along an oblique path through this pipe. A sand metering injection unit (153) is provided at the end of the sand injection pipe.

[0049] The sand quantitative injection unit (153) can supply sand that has passed through the aforementioned quantitative device (151), quantitative opening / closing unit (152), and injection unit inlet (154) to the sand supplied to the sand supply tank (110) in the film-type sand bag processed by the guide rod (160), at an oblique angle, that is, at the aforementioned preset angle (30 to 60°), to the opening surface of the upper part of the film-type sand bag located at the top of the guide rod (160) which is formed as a set spaced apart in front on the sand automatic injection device (100).

[0052] Next, the external force providing part (190) is connected to the vertical movement device (170) and formed at the lower vertical part of the vertical movement device (170), so that it can perform shaking and tapping functions according to the control of the control part (100a).

[0053] That is, the external force providing part (190) can provide a shaking function to locate and insert the sand bag into the area where the sand is injected by the sand injection device (150) by moving the sealing device (180) downward to position (P) by the vertical movement device (170) to position (P') in Fig. 1, and a tapping function according to the external force to search for the blast hole in the area where the blast hole is formed.

[0054] In this manner, when the sand bag with sand injected corresponding to drawing reference numeral 100a is recognized by the control unit (100a) that the sealing of the blast hole in the manner described above is released, the sand bag with sand injected can be lowered by releasing the grips on the sealing device (180) and the external force providing unit (190).

[0056] Meanwhile, the control unit (100a) can count the number of sand bags sealed in sand bags and inserted into the blast hole, and then provide the result to the management server via the network.

[0057] Through this configuration, each sand automatic injection device (100) can collect information on the amount of sand injected into a blast hole formed in a preset area through a sensor module and then provide it to a management server via a network.

[0058] The management server can check the number of blast holes in the requested blasting area for one sand automatic injection device (100), calculate the amount of sand proportional to the number of confirmed holes, and obtain a quantitative value corresponding to the difference from the actual amount used.

[0059] Afterwards, if the calculated quantitative value is used in excess of the amount of sand proportional to the number of holes, the management server determines that there is an abnormality in the blasting area and provides information regarding the quantitative value and the actual amount of sand used to the manager terminal managing each sand automatic injection device (100) to prepare for potential accidents.

[0061] The present invention can also be implemented as computer-readable code on a computer-readable recording medium. A computer-readable recording medium includes all types of recording devices in which data that can be read by a computer system is stored.

[0062] Examples of computer-readable recording media include ROM, RAM, CD-ROM, magnetic tape, floppy disk, optical data storage devices, and also include those implemented in the form of carrier waves (e.g., transmission over the Internet).

[0063] In addition, computer-readable recording media are distributed across networked computer systems, allowing computer-readable code to be stored and executed in a distributed manner.
