Description

  The present invention relates to a sandbag punching machine capable of drilling into a sandbag and discharging the sand out of the sandbag.

  At river construction sites, etc., sandbags filled with local earth and sand in large sandbags are installed in place for the purpose of temporary damming of rivers and protection of soft slopes. Is lifted from a predetermined installation position by a working machine such as a backhoe, and the remaining soil processing (soil removal processing) is performed to discharge the earth and sand as filling material to the site and backfill.

  Conventionally, the remaining soil treatment is to lift the sandbag on a ground surface with a working machine such as a hydraulic excavator, lay it on the ground surface, and after the worker cuts the bag with a cutter, lifts the sandbag again, and the earth and sand in the sandbag Is the work of discharging the bag out of the bag. In such remaining soil disposal work, for workers other than the operator who operates the work machine, work to attach the sandbag to the work machine, work to cut the lying sandbag, and the sandbag from which earth and sand have been discharged Therefore, there is a limit to the number of sandbags that can be processed within a predetermined time (for example, one day). In addition, there is a risk that the worker enters the working radius of the work machine.

  Patent Document 1 below discloses a device having a burr fitting and a cutting fitting on the main body as an opening device for a fluid granular material and a container bag for transporting a liquid, and a metal mesh disposed below. With such a device attached to the inlet of a storage container such as a hopper, the suspended container bag is lowered onto the opening device, and the bottom of the container bag is pierced by the burr fitting installed at the top, and further cut There is a container bag opening method that allows the container bag to be torn by pushing it out with metal fittings, discharges the contents under its own weight, and sifts with a wire mesh at the bottom of the device so that the powder does not fall while it is solidified. Proposed. By adopting such an apparatus and work method, it becomes unnecessary for the worker to break the bottom of the container bag with a cutting tool such as a cutter, and the risk of the contents popping out suddenly falling to the worker during opening work Can also be avoided. Therefore, if such an opening device and an opening method are adopted, it can be considered that the process of opening the soil bag filled with earth and sand and discharging the earth and sand to the outside of the bag can be performed efficiently.

Japanese Patent Laid-Open No. 10-167234

  However, since the above-described opening device is a device for opening a container bag containing fluid particles and liquid as contents, earth and sand having high viscosity are placed on such an opening device. Even if it is possible to lower the filled sandbag and push through and spread the bottom of the sandbag with the burr and cutting hardware, all the sand is discharged from the sandbag at once due to the viscosity of the sand. There is almost no tendency, and there is a very high tendency for the bottom of the sandbag to remain at a location that is not incised by the burr fitting and the cutting fitting. Therefore, when the sandbag lowered on the opening device is lifted again, the earth and sand remaining in the sandbag and the sandbag that is under tension due to the load of such earth and sand are not attached to the cutting and burr caps. As a result, it becomes impossible to lift the sandbags manually, and as a result, it is necessary to lift the sandbags manually by the worker, or to incline the soil and sand remaining in the sandbags to discharge the remaining soil. The discharge process cannot be performed smoothly. In particular, at river construction sites, etc., it usually takes about half a year to one year from filling sandbags with earth and sand to disposing of the remaining soil, and soil that has been exposed to wind and rain for such a long period of time. The earth and sand in the bag is often a lump of soil compared to the time when it was packed in a sandbag, and the above-mentioned problems are likely to occur.

  Furthermore, since the opening device described above has a wire mesh arranged below to screen fluid particles and liquid, if the residual soil treatment is carried out using such a device, the weight of the earth and sand The wire mesh may be damaged. In the first place, the remaining soil treatment at the river construction site, etc. is a process of backfilling the soil contained in the sandbag as it is, so there is no need to screen the soil.

  The present invention has been made paying attention to such circumstances, and its main purpose is to efficiently carry out the residual soil treatment (soil removal process) to return the soil packed in the soil bag at the river construction site, etc. The object is to provide a sandbag drilling machine that can be performed.

  That is, the earthenware drilling machine according to the present invention includes a main body part in which a plurality of frame materials are assembled in a pyramid shape, and a hollow frame-like support frame body that supports the main body part, and the tip is sharpened as the main body part. After the drilling protrusion is placed on the top and the upper blade and the downward blade are placed on the frame material, the sandbag that is lifted and lowered above the main body is pierced by the punching protrusion and punched into the sandbag. It is characterized in that the sandbag is configured to be incisable with the downward blade when the soilbag is incised with the upward blade and the soilbag lowered to a position passing through the position of the downward blade is lifted again.

  Here, in the earthenware drilling machine according to the present invention, the frame material for arranging the upward blade and the downward blade may be at least one of the plurality of frame materials constituting the main body, and the upward blade and the A configuration in which downward blades are disposed, a configuration in which upward blades and downward blades are disposed in two or more frame materials if not all, or a configuration in which upward blades and downward blades are disposed in only one frame material. The present invention can be adopted. Further, in the following description, a sandbag filled with earth and sand is called a sandbag, and the sandbag and the sandbag are distinguished.

  In the case of a sandbag drilling machine according to the present invention, the downward surface (bottom surface) of the sandbag descending from above the main body part is pierced by the perforation projection part arranged on the top of the main body part in which a plurality of frame materials are assembled in a pyramid shape. The perforated opening is pushed with a frame material assembled in a pyramid shape against a sandbag that is perforated in a sandbag and further descends along the height of the body while being guided by the frame material constituting the body. While expanding and cutting, by cutting the cut or uncut portion with an upward blade, the sand and sand in the sandbag can be released toward the support frame body and its periphery from the drilled or cut portion. At the same time, the sand remains in the sandbag when the sandbag is lowered to a position where at least the downward surface of the sandbag passes the location of the downward blade. Even if it is, by cutting the sandbags to be lifted again in downward edge, or a large incision sandbags bag than the time just before lifting, it can be torn.

  Therefore, all the earth and sand that remains in the earthen bag without being discharged from the earthen bag at a stretch by simply lowering the earthen bag from the top of the main body is also lowered by the process of lifting the earthen bag again. By incising, it is possible to increase the degree of incision of the sandbag and the location of the tear, and to discharge the remaining earth and sand to the outside of the sandbag and discharge it toward the support frame body and its periphery. As a result, the sandbag remains smoothly in the sandbag, and the sandbag that is tensioned by the load of the sandbag is caught on the frame material and the incision part, preventing and suppressing the problem of large resistance and lifting the sandbag smoothly. Therefore, it is not necessary to lift the sandbag manually by the worker, or to incline and discharge the sand remaining in the sandbag, and the remaining soil discharge processing can be performed safely and smoothly. In particular, river construction sites where sandbags are often exposed to wind and rain in the outdoors and become a lump of soil from the beginning of containment, for example, for a period of about one year from when soil is stored in a soilbag to the remaining soil treatment, etc. However, by using the sandbag punching machine according to the present invention, the remaining soil discharge processing can be performed efficiently. In addition, when a sandbag is opened using the sandbag drilling machine according to the present invention and the earth and sand are discharged, the worker can move away from the heavy machinery working radius, and the safety of the work is improved.

  In addition, in the earthenware punching machine according to the present invention, the timing of incising the earthen bag with the downward blade is the timing when the earthen soil bag lowered to the position where the downward surface (bottom surface) of the earthbag passes the location of the downward blade is lifted again. For example, when a sandbag lowered to a position where the downward surface of the sandbag does not pass through the location of the downward blade is lifted, the sandbag cannot be incised by the downward blade. However, when carrying out the remaining soil treatment using the sandbag drilling machine according to the present invention, the process of lifting the sandbag down to the position where the downward surface of the sandbag passes the location of the downward blade is performed from above the sandbag drilling machine. It is not necessary to be the first lifting process for the lowered sandbag, and it may be the second and subsequent lifting processes. As an example, lift a sandbag lowered to a position where the downward surface of the sandbag does not pass the location of the downward blade, and then lift the soilbag lowered to a position where the downward surface of the sandbag passes the location of the downward blade. A case can be mentioned.

  Furthermore, since the sandbag punching machine according to the present invention is specialized for residual soil treatment at river construction sites, etc., it is sufficient that the sand and sand contained in the sandbag can be backfilled as it is. It is not necessary to screen the filling material by size and other types, and it is sufficient to apply a hollow frame-shaped support frame body without using a screen with a wire mesh for screening. In addition to the hollow frame-shaped support frame body, the earth and sand in the sandbag are discharged, so that at least a predetermined height position including the grounding portion of the support frame body is buried in the earth and sand. Since the earth and sand itself acts as a weight, the remaining soil processing of the second and subsequent bags can be performed under the condition that the stable installation state of the sandbag drilling machine is maintained.

  The sandbag punching machine according to the present invention may have a constant amount of outward protrusion of the upward blade and the downward blade with respect to the frame material of the main body, but depending on the viscosity and viscosity of the earth and sand If the amount of protrusion of the blade and the downward blade to the outside can be changed, it is highly practical and the remaining soil discharge processing can be further improved in efficiency.

  As a preferred specific example, an aspect in which an incision portion having an upward blade and a downward blade on the outer edge is attached to the frame material and the arrangement angle of the incision portion with respect to the frame material can be changed can be exemplified. If it is such a structure, while changing the arrangement | positioning angle (arrangement attitude | position) of the incision part with respect to a frame material, while being able to change the protrusion amount to the outer side of an upward blade and a downward blade with respect to a frame material, a frame The angle of each cutting edge of the upward blade and the downward blade with respect to the material can also be changed.

  In addition, in order to allow the process of lifting the sandbag drilling machine and moving it to a desired position even when part or all of the support frame is buried in the earth and sand, it is suspended near the top of the main body. It is preferable to use a sandbag punch with a suspended portion. The suspension part may be anything that is used when lifting and moving the earthenware drilling machine, and is composed of parts having an appropriate shape such as a ring shape, a C ring shape, or a chain shape in which rings are connected in a string shape. Can do.

  In particular, the earthenware drilling machine according to the present invention is a direct installation type that is installed directly on the ground surface at a river construction site or the like. Therefore, it is also possible to provide a dedicated spike part in the part of the support frame that touches the ground surface in preference to other parts, but in order to demonstrate a good spike function with a simple configuration, A portion of the support frame body that contacts the ground surface in preference to other portions may be formed of a downward U-shaped frame material. With such a configuration, the downward U-shaped frame material constituting a part of the frame structure of the support frame body itself pierces the ground surface and exhibits a good spike function. When a sand drilling machine is lifted with all or part of it buried in the earth and sand, for example, it may occur if the spike function is secured with parts (突出) partially protruding from the frame structure of the support frame body in plan view. In this respect, there is no problem that the support frame body is difficult to remove from the earth and the lifting work of the earthenware drilling machine cannot be performed smoothly because the earth and sand are loaded on the protruding cage. Also excellent in practicality.

  Moreover, the earthenware drilling machine which concerns on this invention can also comprise a main-body part and a support frame body so that isolation | separation is mutually possible. If it is such a structure, at the time of carrying in / out to a river construction site etc., it can be handled in the state which separated the main-body part and a support frame body, and while being able to aim at space saving, a main-body part or It is also possible to replace only one of the support frame bodies. For example, if the perforation protrusion, upward blade, or downward blade is damaged or blunted, it can be used efficiently if another new body is attached to the support frame while the body is removed from the support frame and repaired. Therefore, the separable structure of the main body and the support frame is extremely useful.

  According to the present invention, a sandbag suspended from above the body can be perforated / incised by a perforation protrusion or an upward blade disposed on the body, and further, the soil can be reopened again. Can be incised with the downward blade of the part, and the earth and sand in the sandbag can be discharged from the perforated part and the incision part to the hollow frame-like support frame body and its surroundings, and the soil contained in the sandbag is removed. It is possible to provide a sandbag drilling machine capable of efficiently performing the remaining soil treatment (soil removal processing).

  Next, with reference to FIG. 5 to FIG. 8, a method for using the sandbag punching machine X according to the present embodiment having such a configuration and an operation thereof will be described. 5 to 8 are diagrams schematically showing the remaining soil treatment process using the sandbag punch X according to the present embodiment corresponding to FIG. 2 for each time series.

  First, for the purpose of temporary damming of rivers and protection of weak slopes, for example, in river construction sites where large sandbags D made of polypropylene or cloth sandbags D1 filled with local earth and sand are installed in place. Then, the earthenware punching machine X according to the present embodiment is carried in, and the earthenware drilling machine X is set in a place where the earth and sand as the filling material of the earthenware D is discharged and backfilled. In this operation, for example, the entire earthenware drilling machine X is lifted and moved in a state where the suspension part 5 of the earthenware drilling machine X is hooked on the hook part J2 of the working machine J such as a hydraulic excavator and lowered to a desired position. Can be done by.

  The place where the earthenware drilling machine X according to the present embodiment is set is a place where the soil is exposed, for example, in a riverbed or the like, and when the earthenware drilling machine X is set in such a place, According to the earthenware drilling machine X of the present embodiment in which the grounding part 7 that contacts the ground surface in preference to other parts is constituted by the channel steel 71 arranged with the opening facing downward, The lower end of the channel steel 71 is pierced so as to sink into the soil by its own weight (see FIG. 5). As a result, the sandbag punch X is set in a stable grounding state. At an appropriate timing before and after the sandbag punch X is set at a predetermined location, the amount of outward protrusion of the upward blade 41 and the downward blade 42 with respect to the frame members 31 and 32 constituting the main body 1 and the angle of the blade edge are adjusted.

  Next, the worker manually removes the hooked state of the suspension part 5 of the earthenware punching machine X from the hook part J2 of the work machine J such as a hydraulic excavator, and puts the earthen D (the earthen bag D1) on the hook part J2. In this state, the sandbag D is lifted by the operation of the operator of the work machine J (the above-mentioned worker can be an operator) and moved to above the sandbag drilling machine X (see FIG. 5). Subsequently, the sandbag D is dropped from above the sandbag drilling machine X by the operation of the operator of the work machine J. At this time, the state where the earthen bag D1 is hooked on the hook portion J2 of the work machine J is maintained. When the sandbag D is lowered from above with respect to the sandbag punch X, the downward surface (bottom portion) of the sandbag D pierces the drilling projection 11 formed at the tip of the main body 1, and a hole is opened in the bottom of the sandbag D1. Thus, the earth and sand in the sandbag D1 is discharged from the opening (see FIG. 6, in each figure after FIG. 6, the earth and sand discharged from the sandbag D1 is schematically shown with a common pattern. Is shown). The discharged earth and sand falls while being guided by the frame members 31 and 32 constituting the hypotenuse of the quadrangular pyramid or without being guided by the frame members 31 and 32, and falls on the hollow support frame body 2 and its periphery. Is released towards.

  When the sandbag D is further lowered, the piercing amount (depth of piercing) of the perforated protrusion 11 with respect to the sandbag D1 increases, and the opening portion of the sandbag D1 that is perforated by the perforated protrusion 11 becomes a pyramid-shaped main body. The frame material (long angle steel 31 and medium angle steel 32) constituting the outer edge portion of 1 can be torn while being spread. When the sandbag is dropped to a position where the bottom of the sandbag D or the vicinity of the bottom is in contact with and passes through the upward blade 41 of the incision portion 4 disposed in the main body 1, the sandbag punch X according to the present embodiment 41, the sandbag D1 is incised, the incision region and the incision location in the sandbag D1 are increased, and the sand in the sandbag D1 can be discharged (see FIG. 7).

  However, 1 ton or 2 tons of earth and sand contained in the sandbag D1 was placed in the field for a period until the remaining soil treatment was started in the state of being accommodated in the sandbag D1, for example, about one year. Therefore, the viscosity / viscosity is relatively high, and it tends to remain in the sandbag D1 without smoothly flowing out from the portion drilled / incised by the drilling protrusion 11 or the upward blade 41.

  Therefore, when performing the remaining soil processing using the sandbag drilling machine X according to the present embodiment, when the sandbag D lowered to a position where the downward surface of the sandbag D passes the position of the downward blade 42 is lifted again, the main body 1 The sandbag D1 is further incised by the downward blade 42 arranged on the sandbag, and the incision area and the incision location in the sandbag D1 are further increased, so that the earth and sand in the sandbag D1 can be discharged smoothly (see FIG. 8). ).

  By repeating the procedure of lowering the sandbag D and lifting it again one or more times, all or almost all of the sand in the sandbag D1 is discharged out of the bag and released toward the support frame body 2 and its periphery. Can be made.

  The sandbag D1 after discharging the earth and sand can be removed from the hook portion J2 of the work machine J by the worker's manual work. Then, the remaining soil processing can be efficiently performed by hooking the sandbag D1 to be processed next for the remaining soil on the hook portion J2 of the work machine J and performing the above-described processing procedure.

  As described above, according to the sandbag punching machine X according to the present embodiment, the punching protrusion 11 disposed on the top of the main body 1 in which the plurality of frame members 31 and 32 are assembled in a pyramid shape is used from above the main body 1. The sandbag D1 that has fallen along the height direction of the main body 1 while being guided by the frame materials 31 and 32 constituting the main body 1 and drilled through the perforated bag D1 that has fallen is further provided. Incision with the upward blade 41 of the incision part 4 disposed in the upper part 41 allows the earth and sand in the sandbag D1 to be discharged toward the support frame body 2 and the periphery thereof, and allows the upward blade 41 of the incision part 4 to pass through. Even when soil and sand remain in the soil bag D1, the soil bag D1 is lifted again and opened with the downward blade 42 of the incision section 4 so that the soil bag D1 is largely opened. Ri can be torn, it is possible to release the sediment in the sandbag D1 from their incision-switching 裂箇 plants towards the 2 and its periphery support framework.

  Therefore, the earth and sand remaining without being discharged from the earthbag bag D1 at the time when the earthbag D is lowered to the position where the downward blade 42 of the incision portion 4 is disposed is also lowered by the downward blade 42 in accordance with the process of lifting the earthbag D again. By incising the earthen bag, the degree of incision and tearing of the earthen bag D1 can be increased, and the earth and sand remaining in the earthen bag D1 can be discharged out of the bag D1, and remains in the earthen bag D1. Smoothing the sandbag D by preventing and suppressing the trouble that the sandbag D1 that is tensioned by the load of the earth and sand itself and the residual sand and sand is caught on the frame materials 31, 32 and the incision 4 and becomes a large resistance. It becomes possible to lift it up. As a result, it is not necessary to lift the sandbag D manually by the worker, or to incline and discharge the sand remaining in the sandbag D1, and the remaining soil discharge processing can be performed smoothly. And, for a predetermined period from when the earthen bag D1 is filled with earth and sand to when the remaining earth processing is started, the earthy sand D is often exposed to wind and rain in the outdoors and the earth and sand in the bag D1 is often a high-viscosity mass. On the other hand, by using the sandbag punch X according to the present embodiment, the remaining soil processing can be performed efficiently.

  Furthermore, since the sandbag punching machine X according to the present embodiment is specialized for residual soil processing at a river construction site or the like, it is sufficient that the earth and sand contained in the sandbag bag D1 can be backfilled as it is. Since it is not necessary to screen the contents in the bag D1 according to size or the like, it is sufficient to apply a hollow frame-shaped support frame 2 without using a screen having a wire mesh for screening. The structure can be simplified, and the earth and sand in the sandbag D1 is discharged into the hollow frame-shaped support frame body 2 so that at least the grounding portion 7 of the support frame body 2 is included. The soil up to the specified height is buried in the earth and the earth and sand itself acts as a weight, so that the remaining soil disposal of the earthbag D after the second bag is performed under the condition that the earthhole drilling machine X is maintained in a stable installation state. Can (see FIGS. 6-8).

  Further, the sandbag punch X according to the present embodiment is configured so that the arrangement angle of the incision portion 4 with respect to the frame material (long angle steel 31 and medium angle steel 32) constituting the main body portion 1 can be changed. Depending on the viscosity and viscosity of the earth and sand, or the preference of the operator who operates the work machine, the amount of protrusion of the upward blade 41 and the downward blade 42 to the outside of the frame members 31 and 32 of the main body 1, and thus the upward blade 41. And the angle which each blade edge | tip of the downward blade 42 faces can be changed, it is rich in practicality, and the further efficiency improvement of the residual soil discharge process can be achieved. As a result of experiments by the present inventors, the higher the viscosity of the earth and sand, the smoother the incision is made by reducing the amount of outward protrusion of the upward blade 41 and the downward blade 42 with respect to the frame materials 31 and 32 of the main body 1. It has been found that processing can be performed.

  Furthermore, since the earthenware punching machine X according to the present embodiment has the suspension part 5 disposed in the vicinity of the top of the main body part 1, the earthenware punching machine even when part or all of the support frame body 2 is buried in the earth and sand. The process of lifting X and moving it to a desired position can be suitably performed (see FIG. 8). Accordingly, for example, a plurality of (for example, 3 to 5 bags) sandbags D can be sequentially processed by the sandbag punching machine X set at an arbitrary position, and each time the sandbag D is processed, Compared to the mode of movement, the remaining soil processing efficiency is dramatically improved.

  In particular, the sandbag drilling machine X according to the present embodiment has a portion of the support frame body 2 that contacts the ground surface in preference to the other portions with a downward U-shaped frame material (with the opening facing downward). Since it is composed of channel steel 71), when installed directly on the ground surface at a river construction site etc., the downward U-shaped frame material 71 itself pierces the ground surface and exhibits a good spike function, It is possible to prevent or suppress the side slip of the earthenware drilling machine X after the installation time, and to support the earthenware drilling machine X in a plan view when it is lifted with part or all of the support frame 2 buried in the earth and sand. If the structure that secures the spike function with a part of the frame structure (frame) of the frame body 2 to ensure the spike function, that is, the earth and sand is loaded on the protruding wall The support frame body 2 can be easily pulled out from the earth and sand without causing the trouble that the support frame body 2 is difficult to remove from the earth and sand, and the lifting operation of the sand drilling machine X cannot be performed smoothly. Is also practical.

  Furthermore, since the sandbag punching machine X according to the present embodiment comprises the main body portion 1 and the support frame body 2 by steel materials and the steel materials are fixed by welding, the strength is high and the durability is excellent. It can be suitably used for residual soil treatment where a load of tons or more is applied.

  In particular, since the earthenware punching machine X according to the present embodiment is provided with the tip reinforcing portion 12 at the top of the main body part 1, the body that receives a large impact when the earthenware D is lowered from above the earthenware drilling machine X. The strength of the top of the part 1 (the perforation protrusion 11) is increased, the deformation of the perforation protrusion 11 is prevented, and the perforation process by the perforation protrusion 11 can be performed appropriately. In the present embodiment, the tip reinforcing portion 12 is formed by forming the upward blade 12a at a portion corresponding to the outer edge (the hypotenuse of the pyramid) of the main body portion 1 having a pyramid shape. Can be actively contributed to the incision of the soil bag D1, and the remaining soil processing can be further improved in efficiency.

  In addition, this invention is not limited to embodiment mentioned above. For example, the main body portion is not limited to a quadrangular pyramid shape, and may be a polygonal pyramid shape such as a triangular pyramid shape or a pentagonal pyramid shape, and the number of frame materials constituting the main body portion is appropriately changed according to the shape of the main body portion. It doesn't matter.

  In addition, as the plurality of frame materials constituting the main body, all of the same shape and the same size can be used, and a frame material other than the steel plate can be applied.

  Further, the perforated protrusion with a sharpened tip disposed on the top of the main body can be formed by an aggregate of all upper ends of a plurality of frame materials constituting the main body, and any selected but not all It can also be formed by an aggregate of the upper end portions of one or more frame members. Furthermore, a mode in which a perforated protrusion having a sharpened tip is formed by a dedicated part separate from the frame material and the perforated protrusion is disposed on the top of the main body may be employed.

  The angle of inclination of the frame material can be configured by changing the degree of sharpness (angle) of the perforated protrusion, or by moving the lower end of the frame material constituting the main body part toward or away from the center of the main body in plan view. You may comprise so that (the angle of the hypotenuse of a pyramid) and the height dimension of a main-body part can be changed.

  In the above-described embodiment, the aspect in which the upward blade and the downward blade are respectively arranged on all the frame materials constituting the main body portion is illustrated, but the upward blade and the downward surface are not provided on all but one or more selected frame materials. The aspect which has arrange | positioned the blade may be sufficient.

  The amount of protrusion of the upward blade and the downward blade arranged on the frame material of the main body and the angle adjustment of the blade edge can be changed steplessly (for example, in the vicinity of the arc portion 43 of the incision portion described above, Instead of the second mounting holes 4b formed at an equal pitch along an arc centered on the one mounting hole 4a, an arc-shaped long hole centering on the first mounting hole 4a is formed, and the frame material of the long holes It is also possible to adopt a configuration in which the position to communicate with the second fixed hole 3b can be selected.

  Also, the amount of outward protrusion of the upward and downward blades arranged on the frame material of the main body is always constant, or the angle of the blade edge of the upward and downward blades arranged on the frame material of the main body is always constant. It may be a constant one. In particular, in the above-described embodiment, an example in which the upward blade and the downward blade are formed on the outer edge of the incision portion, which is a common part, is illustrated, but the upward blade and the downward blade are respectively formed in predetermined portions of individual parts, Parts may be placed on the frame material. Moreover, the earthenware drilling machine of the present invention includes a configuration in which an upward blade and a downward blade are directly formed on the frame material of the main body.
