撹拌機付きユニット体10が本体部9の門型フレーム12間に着脱自在に装着されることにより、ホッパ5からシュート7にわたる一連の中空の搬送通路P内に撹拌機8を多段に配設した混合用筒部2が構成されるようになっている。各撹拌機付きユニット体10は、それらの取付フランジ部23,24を、本体部9の連結フランジ部13,18にボルト・ナットで締結することで、本体部9に装着される。   The unit body 10 with a stirrer is detachably mounted between the gate-type frames 12 of the main body 9, so that the stirrer 8 is arranged in multiple stages in a series of hollow transport passages P extending from the hopper 5 to the chute 7. The mixing cylinder portion 2 is configured. Each unit 10 with a stirrer is attached to the main body 9 by fastening the mounting flanges 23 and 24 to the connecting flanges 13 and 18 of the main body 9 with bolts and nuts.

このようにして構成される混合用筒部2には、混合材料の流下方向に沿って、最上段に配置される第1撹拌機8の下流側に、搬送通路P内を流下する混合材料に給水するための給水部35が設けられる。本実施形態にあっては、給水部35は、門型フレーム12の一対の脚部間に指し渡すことで搬送通路P内に位置させた多孔状のパイプで構成され、このパイプを給水源に接続することにより、パイプから搬送通路P内に散水するようになっている。   In the mixing cylinder portion 2 configured in this way, the mixed material that flows down in the transport passage P is provided downstream of the first stirrer 8 disposed at the uppermost stage along the flow direction of the mixed material. A water supply unit 35 for supplying water is provided. In this embodiment, the water supply part 35 is comprised by the porous pipe located in the conveyance path P by handing between a pair of leg parts of the portal frame 12, and this pipe is used as a water supply source. By connecting, water is sprinkled from the pipe into the transport passage P.

図示例にあっては、給水部35は、最上部の門型フレーム12に続く、上から2番目の門型フレーム12に備えられていて、言い換えれば、最上段に設けられる第1撹拌機8よりも混合材料の流下方向下流側に位置する撹拌機8の上流側に設けられる。給水部35は、一箇所に限らず、必要に応じて複数箇所に設けても良い(図17等参照)。なお、図中、36は、混合用筒部2に設けられ、当該混合用筒部2の傾斜角度を表示する角度計である。   In the example of illustration, the water supply part 35 is provided in the 2nd gate-type flame | frame 12 following the top gate-type flame | frame 12, in other words, the 1st stirrer 8 provided in the uppermost stage. It is provided on the upstream side of the stirrer 8 located on the downstream side of the mixed material flow direction. The water supply part 35 may be provided not only in one place but in multiple places as needed (refer FIG. 17 etc.). In the drawing, reference numeral 36 denotes an angle meter that is provided in the mixing cylinder portion 2 and displays an inclination angle of the mixing cylinder portion 2.

混合用筒部2は、支持装置3によって傾斜状態で支持される。支持装置3は主に、現地に設置されて混合用筒部2が搭載される支持架台37と、支持架台37に基端(下端)が回転自在にピン結合されると共に先端(上端)が混合用筒部2上端側の支持ブラケット16に回転自在にピン結合され、傾動可能な一対の傾倒式固定長ピラー38と、支持架台37と混合用筒部2下端側の連結ブラケット14それぞれに両端がピン結合され、これら支持架台37及び混合用筒部2下端側の間に傾動自在にかつ離脱可能に設けられた一対の支持ピラー39と、支持架台37に一端が回転自在にピン結合されると共に他端が混合用筒部2下端側の連結ブラケット14に回転自在にピン結合され、かつ固定長ピラー38と支持ピラー39の向きと交差する方向に配置されて、混合用筒部2の傾斜角度を調整するために伸縮作動される一対の可変長ピラー40とから構成される。   The mixing cylinder portion 2 is supported in an inclined state by the support device 3. The support device 3 is mainly installed on-site and has a support frame 37 on which the mixing cylinder portion 2 is mounted, and a base end (lower end) is rotatably coupled to the support frame 37 and a front end (upper end) is mixed. A pair of tilting fixed-length pillars 38 that are rotatably pin-coupled to the support bracket 16 on the upper end side of the cylinder section 2 and can be tilted, and a support frame 37 and a connecting bracket 14 on the lower end side of the mixing cylinder section 2 have both ends. A pair of support pillars 39 that are pin-coupled and are provided between the support frame 37 and the lower end side of the mixing cylinder 2 so as to be tiltable and detachable, and one end of the support frame 37 is rotatably coupled to the support frame 37. The other end is rotatably pin-coupled to the connecting bracket 14 on the lower end side of the mixing cylinder portion 2 and is arranged in a direction intersecting with the directions of the fixed-length pillar 38 and the support pillar 39, and the inclination angle of the mixing cylinder portion 2 To adjust Composed of a pair of variable-pillars 40 that are condensation operation.

支持架台37には、固定長ピラー38及び可変長ピラー40を同軸で一括してピン結合する第1ブラケット41と、支持ピラー39をピン結合する第2ブラケット42が配設される。支持ピラー39は、第2ブラケット42及び連結ブラケット14とピン結合される両端のいずれかのピンを外すことにより、支持架台37と混合用筒部2との間から離脱される。可変長ピラー40は、ネジジャッキや油圧シリンダなどの伸縮機構を備える。伸縮操作は、手動であっても、自動であっても良い。   The support frame 37 is provided with a first bracket 41 for pin-fixing the fixed-length pillar 38 and the variable-length pillar 40 collectively and a second bracket 42 for pin-connecting the support pillar 39. The support pillar 39 is detached from between the support frame 37 and the mixing cylinder portion 2 by removing any of the pins at both ends that are pin-coupled to the second bracket 42 and the connection bracket 14. The variable-length pillar 40 includes an expansion / contraction mechanism such as a screw jack or a hydraulic cylinder. The expansion / contraction operation may be manual or automatic.

支持装置3は、混合用筒部2、支持架台37、固定長ピラー38、並びに支持ピラー39による四角形リンクを、可変長ピラー40によって静定化する構造となっている。そして、可変長ピラー40を伸張させると、支持ピラー39が立ち上がりつつ、混合用筒部2は、固定長ピラー38の先端がピン結合された混合用筒部2上端側の支持ブラケット16位置を回転支点として、支持架台37に対する傾斜角度が小さくなる(緩い傾斜となる)。他方、可変長ピラー40を収縮させると、支持ピラー39が倒れつつ、混合用筒部2は、その上端側の支持ブラケット16位置を回転支点として、支持架台37に対する傾斜角度が大きくなる(きつい傾斜となる)。これにより、混合用筒部2の傾斜角度を調整することができる。支持ピラー39については、四角形リンクの動きを円滑にするために、必要に応じて伸縮自在としても良い。   The support device 3 has a structure in which a rectangular link formed by the mixing cylinder portion 2, the support frame 37, the fixed-length pillar 38, and the support pillar 39 is stabilized by the variable-length pillar 40. When the variable-length pillar 40 is extended, the support pillar 39 rises and the mixing cylinder 2 rotates the position of the support bracket 16 on the upper end side of the mixing cylinder 2 to which the tip of the fixed-length pillar 38 is pin-coupled. As a fulcrum, the inclination angle with respect to the support frame 37 becomes smaller (a gentle inclination). On the other hand, when the variable-length pillar 40 is contracted, the support pillar 39 is tilted, and the mixing cylinder portion 2 has an inclination angle with respect to the support frame 37 with the support bracket 16 position on the upper end side as a rotation fulcrum (tight inclination). Becomes). Thereby, the inclination-angle of the cylinder part 2 for mixing can be adjusted. About the support pillar 39, in order to make the motion of a square link smooth, it is good also as a telescopic extension as needed.

本実施形態にあっては、傾倒式固定長ピラー38と支持ピラー39を組み合わせて四角形リンクに構成するようにしているが、固定長ピラー38を支持架台37に対して回転不能に固定することにより、支持ピラー39を省略するようにしても良い。この場合であっても、可変長ピラー40を伸縮させることにより、混合用筒部2は、固定長ピラー38の先端がピン接合された混合用筒部2上端側の支持ブラケット16位置を回転支点として、支持架台37に対する傾斜角度を小さくしたり大きくしたりする角度調整を行うことができる。   In the present embodiment, the tilt-type fixed-length pillar 38 and the support pillar 39 are combined to form a square link. However, the fixed-length pillar 38 is fixed to the support frame 37 so as not to rotate. The support pillar 39 may be omitted. Even in this case, by expanding and contracting the variable-length pillar 40, the mixing cylinder portion 2 rotates the support bracket 16 position on the upper end side of the mixing cylinder portion 2 to which the tip of the fixed-length pillar 38 is pin-joined. As described above, it is possible to perform an angle adjustment to reduce or increase the inclination angle with respect to the support frame 37.

さらに、上記現地採取土砂混合装置1の周辺には、本実施形態にかかる保守設備43が備えられる。保守設備43は、上記支持装置3に加えて、混合用筒部2上端側の吊り用ブラケット17に吊り具44が着脱自在に連結される天井クレーン等の揚重機45と、支持架台37上に設けられ、傾倒式固定長ピラー38を傾斜状態で支持する受け台46と、支持架台37上に設けた反力受けブラケット47及び固定長ピラー38に設けた取付ブラケット48との間に着脱自在に設けたワイヤーやチェーンなどの引張力導入部材49とから主に構成される。   Furthermore, a maintenance facility 43 according to the present embodiment is provided around the locally collected earth and sand mixing device 1. In addition to the support device 3 described above, the maintenance equipment 43 is provided on a lifting machine 45 such as an overhead crane in which a lifting tool 44 is detachably connected to a suspension bracket 17 on the upper end side of the mixing cylinder 2, and a support frame 37. It is detachably provided between a pedestal 46 provided to support the tilted fixed-length pillar 38 in an inclined state, a reaction force receiving bracket 47 provided on the support frame 37 and a mounting bracket 48 provided on the fixed-length pillar 38. It is mainly composed of a tensile force introducing member 49 such as a provided wire or chain.

傾倒式固定長ピラー38には、これを傾倒させる方向が設定されている。また、固定長ピラー38は、支持ピラー39を離脱しかつ可変長ピラー40を連結した状態の混合用筒部2と共に傾倒される。混合用筒部2は、支持ピラー39を離脱することにより、固定長ピラー38と共に傾倒可能となり、揚重機45は、傾倒可能となった混合用筒部2を、固定長ピラー38とともに、吊り用ブラケット17を介して吊り上げ支持するようになっている。   The tilting-type fixed-length pillar 38 has a direction in which it is tilted. Further, the fixed-length pillar 38 is tilted together with the mixing cylinder portion 2 in a state where the support pillar 39 is detached and the variable-length pillar 40 is connected. The mixing cylinder 2 can be tilted together with the fixed-length pillar 38 by detaching the support pillar 39, and the lifting machine 45 can be used to suspend the mixing cylinder 2 that can be tilted together with the fixed-length pillar 38. It is adapted to be lifted and supported via a bracket 17.

受け台46は、固定長ピラー38の設定傾倒方向に位置させて、言い換えれば固定長ピラー38が倒れてくる箇所に配置される。受け台46の上面46aは、固定長ピラー38を傾斜状態の姿勢で支持するために、支持架台37上に固定長ピラー38をピン結合する第1ブラケット41のピン位置よりも高い高さに位置する斜面とされる。固定長ピラー38が傾倒するとき、受け台46の高さと、支持架台37から浮いた傾斜状態の姿勢をとる可変長ピラー40とにより、これらの協働作用で、混合用筒部2は、横倒しで支持架台37上方に浮かせた状態に支持される。この際、混合用筒部2の重心位置は、受け台46直上周辺となるように設定することが好ましい。   The cradle 46 is positioned in the set tilt direction of the fixed-length pillar 38, in other words, is disposed at a location where the fixed-length pillar 38 falls. The upper surface 46a of the cradle 46 is positioned at a height higher than the pin position of the first bracket 41 for pin-fixing the fixed-length pillar 38 on the support frame 37 in order to support the fixed-length pillar 38 in an inclined posture. It is said to be a slope. When the fixed-length pillar 38 is tilted, the mixing cylinder portion 2 is laid sideways by the cooperative action of the height of the cradle 46 and the variable-length pillar 40 that is in an inclined state floating from the support frame 37. And is supported in a state of floating above the support frame 37. At this time, the position of the center of gravity of the mixing cylinder portion 2 is preferably set so as to be in the vicinity immediately above the cradle 46.

引張力導入部材49は、巻き取りリールやチェーンブロックなどを備えて、巻き取り巻き戻しにより、長さ調整可能とされる。引張力導入部材49は、混合用筒部2に連結された固定長ピラー38を反力受けブラケット47側へ引き込む引張力が導入されるようになっている。具体的には、引張力導入部材49は、揚重機45で吊り上げ支持された混合用筒部2及びこれに連結されている固定長ピラー38が不測の方向へ傾倒することを防ぐために、固定長ピラー38を介して混合用筒部2を設定傾倒方向へ引張する引張力が入力される。   The tensile force introducing member 49 includes a take-up reel, a chain block, and the like, and the length can be adjusted by winding and rewinding. The tensile force introducing member 49 is adapted to introduce a tensile force that pulls the fixed-length pillar 38 connected to the mixing cylinder portion 2 toward the reaction force receiving bracket 47 side. Specifically, the tensile force introducing member 49 has a fixed length in order to prevent the mixing cylinder portion 2 lifted and supported by the lifting machine 45 and the fixed-length pillar 38 connected thereto from tilting in an unexpected direction. A tensile force for pulling the mixing cylinder portion 2 in the set tilt direction is input via the pillar 38.

まず、現地採取土砂混合装置1の稼働状況について説明する。混合用筒部2は、支持架台37上に傾斜状態で設置される。各撹拌機付きユニット体10のモータ29が起動され、各撹拌機付きユニット体10の撹拌機8が個別独立に、個々のモータ29で回転駆動される。また、門型フレーム12に備えた給水部35から搬送通路P内への散水が開始される。混合用筒部2上端のホッパ5に、搬入手段4から混合材料を投下すると、投下された混合材料は、重力の作用で混合用筒部2の搬送通路P内へと流下していく。本実施形態では、搬入手段4からは、現地採取土砂とセメントを混合したドライな混合材料が投下される。   First, the operation status of the locally collected soil mixing apparatus 1 will be described. The mixing cylinder portion 2 is installed on the support frame 37 in an inclined state. The motor 29 of each unit body 10 with a stirrer is started, and the stirrer 8 of each unit body 10 with a stirrer is rotationally driven by each motor 29 individually and independently. Further, water spraying from the water supply unit 35 provided in the portal frame 12 into the transport path P is started. When the mixed material is dropped from the carry-in means 4 onto the hopper 5 at the upper end of the mixing cylinder 2, the dropped mixed material flows down into the conveyance path P of the mixing cylinder 2 by the action of gravity. In this embodiment, from the carrying-in means 4, the dry mixed material which mixed local collection earth and sand and cement is dropped.

流下する混合材料は、最上段の第1撹拌機8により、ドライな状態で空練りされる。空練りされた混合材料は、給水部35を有する門型フレーム12を経過して、搬送通路P内を次段の撹拌機8に向かって流下していく。給水部35を通過する際、混合材料は、水が添加されて、その後は湿潤状態で流下していく。混合材料はその後も、流下による混合作用と、多段に配設されている撹拌機8による撹拌作用とによって、混合撹拌され、混合用筒部2下端に達してシュート7から搬出手段6へと排出される。これにより、混合材料の混合撹拌が達成される。   The mixed material flowing down is kneaded in a dry state by the first stirrer 8 at the uppermost stage. The air-kneaded mixed material passes through the gate-shaped frame 12 having the water supply unit 35 and flows down in the transport path P toward the agitator 8 in the next stage. When passing through the water supply unit 35, the mixed material is added with water and thereafter flows down in a wet state. Thereafter, the mixed material is mixed and agitated by the mixing action by flowing down and the agitating action by the stirrer 8 arranged in multiple stages, reaches the lower end of the mixing cylinder 2 and is discharged from the chute 7 to the unloading means 6. Is done. Thereby, mixing stirring of the mixed material is achieved.

上記説明では、ホッパ5にドライな混合材料を投下する場合について説明したが、ホッパ投入前に混合材料に水を添加して、湿潤状態にした混合材料をホッパ5に投下するようにしても良い。この場合においても、必要に応じて追加的に給水部35から給水を行うようにしても良い。もちろん、給水部35からの給水を行わないようにしても良い。   In the above description, the case where the dry mixed material is dropped onto the hopper 5 has been described. However, the wet mixed material may be dropped onto the hopper 5 by adding water to the mixed material before feeding the hopper. . Also in this case, water may be additionally supplied from the water supply unit 35 as necessary. Of course, the water supply from the water supply unit 35 may not be performed.

次に、混合用筒部2の傾斜角度調整について説明する。混合用筒部2は、支持架台37上に、傾倒式固定長ピラー38と、支持ピラー39と、可変長ピラー40とによって一定傾斜角度で支持されている。混合用筒部2の傾斜角度を調整する際には、可変長ピラー40を伸張させたり、収縮させる。可変長ピラー40を伸張させると、混合用筒部2は、固定長ピラー38先端とピン結合された支持ブラケット16回りに回転され、これにより混合用筒部2を、支持架台37に対する傾斜角度が小さくなるように調整することができる。他方、可変長ピラー40を収縮させると、混合用筒部2は、その上端の支持ブラケット16回りに回転され、これにより混合用筒部2を、支持架台37に対する傾斜角度が大きくなるように調整することができる。   Next, the inclination angle adjustment of the mixing cylinder portion 2 will be described. The mixing cylinder portion 2 is supported on the support frame 37 by a tilt-type fixed-length pillar 38, a support pillar 39, and a variable-length pillar 40 at a constant inclination angle. When adjusting the inclination angle of the mixing cylinder portion 2, the variable length pillar 40 is expanded or contracted. When the variable-length pillar 40 is extended, the mixing cylinder 2 is rotated around the support bracket 16 that is pin-coupled to the tip of the fixed-length pillar 38, whereby the mixing cylinder 2 is inclined with respect to the support frame 37. It can be adjusted to be smaller. On the other hand, when the variable-length pillar 40 is contracted, the mixing cylinder 2 is rotated around the support bracket 16 at the upper end thereof, thereby adjusting the mixing cylinder 2 so that the inclination angle with respect to the support frame 37 becomes large. can do.

以下に、本実施形態にかかる現地採取土砂混合装置の保守方法を、図1〜図3,並びに図12〜図16を用いて説明する。保守作業前にあっては、現地採取土砂混合装置1の混合用筒部2は、支持装置3によって傾斜状態で支持されている。   Below, the maintenance method of the local collection earth and sand mixing apparatus concerning this embodiment is demonstrated using FIGS. 1-3, and FIGS. 12-16. Before the maintenance work, the mixing cylinder portion 2 of the on-site sampling soil mixing device 1 is supported by the support device 3 in an inclined state.

まず、図12に示すように、揚重機45の吊り具44を混合用筒部2上端側の吊り用ブラケット17に装着し、揚重機45に、混合用筒部2を吊り上げ支持する吊り上げ荷重を発生させる。また、混合用筒部2下端側の連結ブラケット14に支持ピラー39の一端をピン結合しているピンを外し、混合用筒部2及び支持架台37の間から支持ピラー39を離脱させる。これにより、混合用筒部2の吊り工程が完了する。   First, as shown in FIG. 12, the lifting tool 44 of the lifting machine 45 is attached to the lifting bracket 17 on the upper end side of the mixing cylinder part 2, and the lifting load that lifts and supports the mixing cylinder part 2 is applied to the lifting machine 45. generate. Further, the pin that connects one end of the support pillar 39 to the connecting bracket 14 on the lower end side of the mixing cylinder 2 is removed, and the support pillar 39 is detached from between the mixing cylinder 2 and the support frame 37. Thereby, the suspension process of the mixing cylinder part 2 is completed.

次に、揚重機45で混合用筒部2を吊り上げ支持した状態で、可変長ピラー40を伸張もしくは収縮させ、これにより、固定長ピラー38を受け台46上に傾斜状態で支持させたときに、混合用筒部2がほぼ水平の横倒し状態となる傾倒時角度に当該混合用筒部2の角度を調整する。具体的には、第1ブラケット41により一括してピン接合した固定長ピラー38及び可変長ピラー40と混合用筒部2とで形成される三角形状に関し、角度調整可能な混合用筒部2の傾斜角度を、「混合用筒部2を水平横倒し状態としかつ固定長ピラー38を受け台46上で傾斜状態に支持する条件を満足する傾倒時角度」に、可変長ピラー40で調整する。これにより、混合用筒部2の傾倒時角度調整工程が完了する。   Next, when the variable length pillar 40 is expanded or contracted in a state where the mixing cylinder portion 2 is lifted and supported by the lifting machine 45, thereby supporting the fixed length pillar 38 on the receiving base 46 in an inclined state. Then, the angle of the mixing cylinder portion 2 is adjusted to the angle at which the mixing cylinder portion 2 is tilted so that the mixing cylinder portion 2 is in a substantially horizontal sideways state. Specifically, regarding the triangular shape formed by the fixed-length pillar 38 and the variable-length pillar 40 and the mixing cylinder portion 2 that are collectively pin-joined by the first bracket 41, the angle adjustment of the mixing cylinder portion 2 is possible. The tilt angle is adjusted by the variable-length pillar 40 to “the tilt angle satisfying the condition that the mixing cylinder portion 2 is horizontally tilted and the fixed-length pillar 38 is supported in the tilted state on the receiving base 46”. Thereby, the angle adjustment process at the time of inclination of the cylinder part 2 for mixing is completed.

次に、図12に示すように、引張力導入部材49を固定長ピラー38の取付ブラケット48に連結する。この連結作業は、吊り工程や傾倒時角度調整工程で完了しておいても良い。引張力導入部材49を固定長ピラー38に連結した状態で、揚重機45の吊り具44の移動及び引張力導入部材49の巻き取りにより、混合用筒部2を支持架台37や受け台46に向けて傾倒させていく。このように傾倒させていくことで、混合用筒部2の重心位置が設定傾倒方向に移動する。重心位置が設定傾倒方向に移動すれば、混合用筒部2や固定長ピラー38の倒れ方向は安定するので、その後、引張力導入部材49を取付ブラケット48から外して撤去する。これにより、混合用筒部2の傾倒操作工程が完了する。   Next, as shown in FIG. 12, the tensile force introducing member 49 is connected to the mounting bracket 48 of the fixed-length pillar 38. This connecting work may be completed in the hanging process or the tilting angle adjusting process. With the tensile force introducing member 49 connected to the fixed-length pillar 38, the mixing cylinder 2 is moved to the support frame 37 and the cradle 46 by moving the lifting tool 44 of the lifting machine 45 and winding the tensile force introducing member 49. Tilt towards. By tilting in this way, the position of the center of gravity of the mixing cylinder portion 2 moves in the set tilt direction. If the position of the center of gravity moves in the set tilt direction, the tilt direction of the mixing cylinder portion 2 and the fixed-length pillar 38 is stabilized, and thereafter, the tensile force introducing member 49 is removed from the mounting bracket 48 and removed. Thereby, the tilting operation process of the mixing cylinder part 2 is completed.

次に、揚重機45により混合用筒部2を支持架台37に向かって下降させる。混合用筒部2を下降させると、図13に示すように、固定長ピラー38が受け台46上に載置される。混合用筒部2は、可変長ピラー40によって傾倒時角度にセットされているので、固定長ピラー38を受け台46で傾斜状態に支持すると、自動的に、固定長ピラー38と可変長ピラー40が協働して、混合用筒部2を横倒しで支持架台37上方に浮かせた状態に支持することができる。これにより、混合用筒部2の横倒し支持工程が完了する。   Next, the mixing cylinder part 2 is lowered toward the support frame 37 by the lifting machine 45. When the mixing cylinder portion 2 is lowered, the fixed-length pillar 38 is placed on the cradle 46 as shown in FIG. Since the mixing cylinder 2 is set at the tilt angle by the variable-length pillar 40, when the fixed-length pillar 38 is supported in an inclined state by the cradle 46, the fixed-length pillar 38 and the variable-length pillar 40 are automatically used. In cooperation, the mixing cylinder portion 2 can be supported in a state where it is laid down and floated above the support frame 37. Thereby, the sideways support process of the mixing cylinder part 2 is completed.

混合用筒部2を横倒し支持した状態で、適宜に点検保守作業を実施する。当該作業に際しては、混合用筒部2の点検口19は、当該混合用筒部2を受け台46で浮かせて支持した際に支持架台37に面することとなるので、開閉扉21により当該点検口19を開けることで、混合用筒部2の下側から搬送通路P内を点検保守することができる。搬送通路P内に混合材料が滞留していれば、点検口19から支持架台37上に排土することもできる。また、天部開閉蓋32及び側部開閉蓋33を取り外すことでも、搬送通路P内の点検保守を行うことができる。   Inspection and maintenance work is appropriately performed in a state where the mixing cylinder portion 2 is laid down and supported. During the operation, the inspection port 19 of the mixing cylinder portion 2 faces the support frame 37 when the mixing cylinder portion 2 is lifted and supported by the receiving base 46. By opening the opening 19, the inside of the transport path P can be inspected and maintained from the lower side of the mixing cylinder portion 2. If the mixed material stays in the transport path P, it can be discharged onto the support frame 37 from the inspection port 19. Moreover, the inspection and maintenance in the conveyance path P can also be performed by removing the top opening / closing lid 32 and the side opening / closing lid 33.

さらに、撹拌機付きユニット体10単位で交換を行うこともできる。交換する際には、混合用筒部2の本体部9に対し、撹拌機付きユニット体10の取り外しを行い、交換する別の撹拌機付きユニット体10の装着を行う。撹拌機付きユニット体10の取り外しは、その取付フランジ部23,24を本体部9の連結フランジ部13,18から取り外せばよい。その後、図14に示すように、混合用筒部2から離脱させた揚重機10の吊り具44を撹拌機付きユニット体10の適宜箇所に連結し、揚重して撤去する。   Furthermore, replacement can be performed in units of 10 units with a stirrer. When exchanging, the unit body 10 with a stirrer is removed from the main body part 9 of the mixing cylinder part 2 and another unit body 10 with a stirrer to be replaced is attached. The unit body 10 with a stirrer can be removed by removing the mounting flange portions 23 and 24 from the connecting flange portions 13 and 18 of the main body portion 9. Thereafter, as shown in FIG. 14, the lifting tool 44 of the lifting machine 10 detached from the mixing cylinder portion 2 is connected to an appropriate portion of the unit body 10 with a stirrer and lifted and removed.

その後、図15に示すように、交換する別の撹拌機付きユニット体10を揚重機45で搬入し、門型フレーム12間に装着するように本体部9へ吊り降ろして、その取付フランジ部23,24と本体部9の連結フランジ部13,18とを締結する。この際、各撹拌機付きユニット体10にモータ29を個別に備えたので、交換対象の撹拌機付きユニット体10の吊り上げ・吊り降ろしだけで交換を完了することができる。したがって、撹拌機付きユニット体10相互間で作業を行う必要がなく、簡単に作業を完了することができる。これにより、ユニット体交換工程が完了する。   After that, as shown in FIG. 15, another unit body 10 with a stirrer to be exchanged is carried by the lifting machine 45, suspended from the main body 9 so as to be mounted between the portal frames 12, and the mounting flange portion 23. 24 and the connecting flange portions 13 and 18 of the main body 9 are fastened. At this time, since each unit body 10 with a stirrer is individually provided with a motor 29, the replacement can be completed only by lifting and lowering the unit body 10 with a stirrer to be replaced. Therefore, it is not necessary to perform work between the unit bodies 10 with a stirrer, and the work can be completed easily. Thereby, a unit body exchange process is completed.

点検保守作業が完了した後は、図16に示すように、揚重機45の吊り具44を混合用筒部2の吊り用ブラケット17に連結し、混合用筒部2を吊り上げ支持する。また、固定長ピラー38の取付ブラケット48に、引張力導入部材49を装着する。その後、固定長ピラー38及び混合用筒部2が設定傾倒方向とは異なる方向へ倒れることがないように、引張力導入部材49を、これに引張力を加えつつ巻き戻しながら揚重機45の吊り具44を移動して、固定長ピラー38と共に混合用筒部2を立ち上げていく。これにより、混合用筒部2の立ち上げ操作工程が完了する。   After the inspection and maintenance work is completed, as shown in FIG. 16, the lifting tool 44 of the lifting machine 45 is connected to the hanging bracket 17 of the mixing cylinder 2 to lift and support the mixing cylinder 2. In addition, a tensile force introducing member 49 is attached to the mounting bracket 48 of the fixed-length pillar 38. Thereafter, the tensile force introducing member 49 is suspended by lifting the lifting machine 45 while unwinding the tensile force introducing member 49 while applying a tensile force so that the fixed-length pillar 38 and the mixing cylinder portion 2 do not fall in a direction different from the set tilting direction. The tool 44 is moved, and the mixing cylinder portion 2 is raised together with the fixed-length pillar 38. Thereby, the starting operation process of the mixing cylinder part 2 is completed.

次いで、可変長ピラー40を伸縮動作して、混合用筒部2の角度を、傾倒時角度から操業時角度に角度調整し、これにより混合用筒部2の操業時角度調整工程が完了する。   Next, the variable-length pillar 40 is expanded and contracted to adjust the angle of the mixing cylinder part 2 from the tilted angle to the operating angle, thereby completing the operating angle adjusting process of the mixing cylinder part 2.

最後に、支持架台37の第2ブラケット42にピン接合されている支持ピラー39の一端を混合用筒部2の連結ブラケット14に、ピンを差し込んでピン接合する。その後、混合用筒部2の吊り用ブラケット17から揚重機45の吊り具44を撤去する。必要に応じて、引張力導入部材49も撤去する。これにより、混合用筒部2を支持架台37上に、固定長ピラー38、支持ピラー39及び可変長ピラー40で傾斜状態に支持することができて、現地採取土砂混合装置1を再稼働させることができる復帰完了工程が完了する。   Finally, one end of the support pillar 39 pin-bonded to the second bracket 42 of the support frame 37 is inserted into the connection bracket 14 of the mixing cylinder portion 2 to be pin-bonded. Thereafter, the hoisting tool 44 of the lifting machine 45 is removed from the hoisting bracket 17 of the mixing cylinder 2. If necessary, the tensile force introducing member 49 is also removed. Thereby, the mixing cylinder part 2 can be supported on the support frame 37 in an inclined state by the fixed-length pillar 38, the support pillar 39, and the variable-length pillar 40, and the on-site sampling soil mixing apparatus 1 can be restarted.

A tilt-type fixed-length pillar 38, which is freely pin-coupled and whose tip is rotatably pin-coupled to the upper end side of the mixing cylinder part 2, and can be tilted between the support frame 37 and the lower end side of the mixing cylinder part 2 and One end of the support pillar 39 provided so as to be detachable and the support frame 37 are rotatably pin-coupled, and the other end is rotatably pin-coupled to the mixing cylinder 2 so that the inclination angle of the mixing cylinder 2 is increased. A variable-length pillar 40 that is expanded and contracted to adjust, a lifting machine 45 for lifting and supporting the mixing cylinder portion 2 supported by a fixed-length pillar 38 that can be tilted with the support pillar 39 detached, and an appropriate height On the support frame 37 The fixed-length pillar 38 is provided so as to be positioned in the set tilting direction, and in cooperation with the variable-length pillar 40, the tilted fixed-length pillar is tilted in order to support the mixing cylinder portion 2 by lying down and floating above the support frame 37. The supporting cylinder 37 is supported in an inclined state, and is detachably provided between the support frame 37 and the fixed-length pillar 38, and the mixing cylinder portion 2 supported by being lifted and supported by the lifting machine 45 is pulled in the set tilting direction. A tensile force introducing member 49 into which a tensile force is introduced, and using the maintenance equipment 43, the mixing cylinder 2 is lifted and supported by the lifting machine 45 and the support pillar 39 is supported by the mixing cylinder 2 and the support. A suspension step for separating from the gantry 37, a tilting angle adjusting step for adjusting the mixing cylinder portion 2 to a tilting angle by the variable length pillar 40, and a mixing cylinder portion by the lifting machine 45 and the tensile force introducing member 49 Receive 2 Tilt operation step of tilting toward the base 46 and removing the tensile force introducing member 49 in response to the center of gravity of the mixing cylinder portion 2 moving in the set tilt direction, and the mixing cylinder portion 2 by the lifting machine 45 By moving down and placing the fixed-length pillar 38 on the receiving base 46, the side-by-side support that supports the mixing cylinder 2 in a state where it is laid down and floated above the support frame 37 in cooperation with the variable-length pillar 40. Since the process is performed, the mixing cylinder part 2 is easily shifted to the laid-down state, which is the maintenance inspection posture, without removing most of the various members of the support device 3 that supports the mixing cylinder part 2. In addition, it is only necessary to start up the mixing cylinder portion 2 with the lifting machine 45, and it is possible to carry out the laying down and the recovery operation easily and in a short time.

また、受け台46と可変長ピラー40を備え、混合用筒部2の傾倒時角度調整工程を実施するようにしたので、混合用筒部2を支持架台37上方に浮かせた状態でほぼ水平に横倒しすることができる。混合用筒部2を、支持架台37上面に直に設置すると横倒し時に混合用筒部2の下面に対し、何らの作業も行うことができない不都合があるが、本実施形態にあっては、混合用筒部2の下側から保守点検や排土を行うことができて、効率よくかつ十分に現地採取土砂混合装置1の点検保守を実施することができる。   In addition, since the gantry 46 and the variable length pillar 40 are provided and the angle adjustment process at the time of tilting of the mixing cylinder portion 2 is performed, the mixing cylinder portion 2 is floated almost horizontally above the support frame 37. Can lie down. If the mixing cylinder part 2 is installed directly on the upper surface of the support frame 37, there is a disadvantage that no operation can be performed on the lower surface of the mixing cylinder part 2 when lying down. Maintenance inspection and soil removal can be performed from the lower side of the cylinder section 2, and the inspection and maintenance of the locally collected soil mixing apparatus 1 can be performed efficiently and sufficiently.

また、引張力導入部材49を備えているので、混合用筒部2や固定長ピラー38が不測の方向へ傾倒することを規制することができ、傾倒操作工程の作業安全性を高めることができる。   Moreover, since the tensile force introducing member 49 is provided, it is possible to restrict the mixing cylinder portion 2 and the fixed-length pillar 38 from being tilted in an unexpected direction, and to improve the work safety of the tilting operation process. .

また、混合用筒部2には少なくとも、受け台46で浮かせて支持した際に支持架台37に面する点検口19を設けたので、具体的には本体部9の底部11に設けたので、混合用筒部2の点検保守を効率よく的確に行うことができる。   In addition, since the mixing cylinder portion 2 is provided with the inspection port 19 that faces the support frame 37 when it is floated and supported by the cradle 46, specifically, it is provided at the bottom portion 11 of the main body portion 9. Inspection and maintenance of the mixing cylinder portion 2 can be performed efficiently and accurately.

また、混合用筒部2を、混合材料の流下を案内する底部11及び混合材料の流下方向に間隔を隔てて底部11にこれを跨ぐ方向に配設された複数の門型フレーム12を備える本体部9と、撹拌機8及び撹拌機8を駆動するモータ29を有し、本体部9の門型フレーム12間に着脱自在に装着されて、底部11を覆って搬送通路Pを区画形成する複数の撹拌機付きユニット体10とから形成し、横倒し支持工程の後、撹拌機付きユニット体10の交換を行うユニット体交換工程を実施するようにしているので、例えば混合用筒部2から揚重機45を離脱させて当該揚重機45により撹拌機付きユニット体10を交換することができて、故障した撹拌機付きユニット体10を迅速かつ簡単に新しいものに交換することができる。これにより、現地採取土砂混合装置1の復旧を短時間で完了することができる。   Further, the mixing cylinder portion 2 includes a bottom portion 11 that guides the flow of the mixed material, and a plurality of gate-type frames 12 that are disposed in a direction across the bottom portion 11 with an interval in the flow direction of the mixed material. A plurality of parts 9, a stirrer 8, and a motor 29 for driving the stirrer 8, which are detachably mounted between the portal frame 12 of the main body part 9 and cover the bottom part 11 to form a conveyance path P. Since the unit body replacement step for replacing the unit body 10 with a stirrer is performed after the sideways support step, the unit body with the stirrer 10 is carried out. The unit body 10 with the stirrer can be replaced by the lifting machine 45 after the 45 is detached, and the unit body 10 with the stirrer that has failed can be replaced with a new one quickly and easily. Thereby, restoration of field collection earth and sand mixing device 1 can be completed in a short time.

また、保守作業が終了した後に、揚重機45により混合用筒部2を吊り上げ支持すると共に、引張力導入部材49を固定長ピラー38に装着し、固定長ピラー38と共に混合用筒部2を立ち上げていく立ち上げ操作工程と、可変長ピラー40により、混合用筒部2を操業時角度に調整する操業時角度調整工程と、支持架台37及び混合用筒部2下端側の間に支持ピラー39を装着し、その後、混合用筒部2から揚重機45を撤去する復帰完了工程とを実施するようにしているので、現地採取土砂混合装置1の復旧にあたっての混合用筒部2の立ち上げを安全に行うことができると共に、この復旧過程で、支持ピラー39を装着する前に、混合用筒部2の操業時角度調整を行うので、支持ピラー39を取り付けた後よりも簡便に混合用筒部2の角度調整を行うことができる。   In addition, after the maintenance work is finished, the mixing cylinder part 2 is lifted and supported by the lifting machine 45, the tensile force introducing member 49 is attached to the fixed-length pillar 38, and the mixing cylinder part 2 is raised together with the fixed-length pillar 38. Supporting pillar between the support frame 37 and the mixing cylinder part 2 lower end side, the starting operation process of raising, the operation angle adjustment process of adjusting the mixing cylinder part 2 to the operation angle by the variable length pillar 40 39, and after that, the return completion process of removing the lifting machine 45 from the mixing cylinder 2 is carried out, so that the mixing cylinder 2 is started up for the restoration of the locally collected soil mixing apparatus 1 In this recovery process, the angle adjustment during operation of the mixing cylinder portion 2 is performed before the support pillar 39 is mounted, so that it is easier to mix than after the support pillar 39 is attached. Of the cylinder part 2 It is possible to perform the time adjustment.

上記保守設備43及び保守方法が適用される本実施形態の現地採取土砂混合装置1にあっては、混合用筒部2を、混合材料の流下を案内する底部11及び混合材料の流下方向に間隔を隔てて底部11にこれを跨ぐ方向に配設された複数の門型フレーム12を備える本体部9と、撹拌機8及び撹拌機8を駆動するモータ29を有し、本体部9の門型フレーム12間に着脱自在に装着されて、底部11を覆って搬送通路Pを区画形成する複数の撹拌機付きユニット体10とから形成したので、いずれかの撹拌機8が故障した場合など、いずれかの撹拌機付きユニット体10が運転不能となっても、その他の撹拌機付きユニット体10は個々にモータ29を備えてそれらの稼働は可能であり、従って、支障が生じた撹拌機付きユニット体10単体を交換するだけで装置1を復旧することができる。   In the field-collected earth and sand mixing apparatus 1 of the present embodiment to which the maintenance facility 43 and the maintenance method are applied, the mixing cylinder portion 2 is spaced apart from the bottom portion 11 that guides the flow of the mixed material and the flow direction of the mixed material. A main body 9 having a plurality of portal frames 12 arranged in a direction across the bottom 11 across the bottom 11, a stirrer 8 and a motor 29 for driving the stirrer 8. Since it is formed by a plurality of unit bodies 10 with stirrers that are detachably mounted between the frames 12 and cover the bottom 11 to form the conveyance path P, any one of the stirrers 8 breaks down. Even if the unit body 10 with a stirrer becomes inoperable, the other unit bodies 10 with a stirrer are individually provided with the motors 29 and can be operated, and accordingly, the unit with a stirrer in which trouble has occurred Body 10 alone It is possible to recover only in the apparatus 1 for conversion.

その交換作業も、本体部9に対し着脱自在とした撹拌機付きユニット体10を、例えばフランジ部13,18,23,24における連結を脱着するだけで、取り外したり、取り付けることができ、容易である。容易な交換作業で撹拌機付きユニット体10を取り替えるだけで、その後は、装置1を復旧して稼働させることができ、混合用筒部2に組み込んだ状態で故障した撹拌機8を修理する場合などに比べて、格段に復旧時間を短縮することができる。   For the replacement work, the unit body 10 with a stirrer that is detachable from the main body 9 can be easily removed and attached by simply detaching the connection at the flanges 13, 18, 23, 24, for example. is there. When the unit body 10 with a stirrer is simply replaced by an easy replacement operation, the apparatus 1 can be restored and operated thereafter, and the broken stirrer 8 is repaired while it is incorporated in the mixing cylinder 2. Compared to the above, the recovery time can be significantly shortened.

取り外した撹拌機付きユニット体10については、これを対象として保守点検などの措置を自在に講ずることができる。   About the unit body 10 with a stirrer which removed, measures, such as a maintenance check, can be taken freely about this.

また、混合用筒部2を、撹拌機付きユニット体10と、これらが脱着される本体部9とで構成していて、撹拌機付きユニット体10を取り外しても、これによって混合用筒部2が元の形態を維持できずにバラバラになるようなことはなく、従って、撹拌機付きユニット体10の交換作業についても、上述したように容易であると共に、交換に要する作業時間を短縮することができる。   Further, the mixing cylinder part 2 is composed of the unit body 10 with a stirrer and the main body part 9 from which these are attached and detached. Even if the unit body 10 with a stirrer is removed, the mixing cylinder part 2 is thereby removed. However, the original form cannot be maintained and the unit body with a stirrer 10 can be easily replaced as described above, and the work time required for the replacement can be shortened. Can do.

このように、撹拌機付きユニット体10毎に交換でき、交換後は、故障していない撹拌機付きユニット体10を含めてそれら個々に備えたモータ29を起動すれば運転を再開することができるので、交換後にさらに撹拌機8同士をチェーン連結したり、バラバラになるユニット体10を直結して混合用筒部2を組み立てる場合に比べて、格段に容易かつ短時間で現地採取土砂混合装置1を復旧して再稼働することができる。   Thus, it can replace | exchange for every unit body 10 with a stirrer, and after replacement | exchange, operation | movement can be restarted if the motor 29 with which each was equipped including the unit body 10 with a stirrer which has not failed is started. Therefore, compared to the case where the agitators 8 are further chain-connected after the replacement or the mixing cylinder part 2 is assembled by directly connecting the unit bodies 10 to be separated, the locally collected soil mixing apparatus 1 is remarkably easily and in a short time. Can be recovered and restarted.

また、混合材料として現地採取土砂及びセメントが上端から投入される混合用筒部2と、混合用筒部2の撹拌機8のうち、最上段に設けられて混合材料を空練りする第1撹拌機8と、混合材料の流下方向に沿って第1撹拌機8よりも下流側に設けられ、搬送通路P内を流下する混合材料に給水する給水部35とを備えていて、第1撹拌機8による空練りによって現地採取土砂とセメントとを、重力による流下作用で行われる混合だけに頼ることなく、十分かつ均一に撹拌混合することができ、その後に給水部35から加水するので、水を含めて混合撹拌するすべての材料を一気にホッパから投入する場合に比べて、良好かつ合理的な撹拌混合を行うことができる。すなわち、混合用筒部2に混合材料の流下方向に沿って、構造的に混練ステップを分けたり、混練ステップを設定することができて、搬送通路P内で適切に混合材料を混合撹拌することができる。   Moreover, the 1st stirring which is provided in the uppermost stage among the mixing cylinder part 2 into which field collection soil and cement are thrown in from the upper end as mixing material, and the stirrer 8 of the mixing cylinder part 2 is kneaded with mixing material. And a water supply unit 35 that is provided on the downstream side of the first stirrer 8 along the flow direction of the mixed material and feeds the mixed material flowing down in the conveyance path P, and includes the first stirrer. The ground collected soil and cement can be stirred and mixed sufficiently and uniformly without relying only on the mixing performed by the flow-down action due to gravity, and then water is added from the water supply unit 35. Compared to the case where all the materials to be mixed and stirred are put in from the hopper at once, good and rational stirring and mixing can be performed. That is, the kneading step can be structurally divided or set in the mixing cylinder portion 2 along the flow direction of the mixed material, and the mixed material can be appropriately mixed and stirred in the transport path P. Can do.

また、混合用筒部2を、混合材料の流下を案内する底部11及び混合材料の流下方向に間隔を隔てて底部11にこれを跨ぐ方向に配設された複数の門型フレーム12を備える本体部9と、撹拌機8及び撹拌機8を駆動するモータ29を有し、本体部9の門型フレーム12間に着脱自在に装着されて、底部11を覆って搬送通路Pを区画形成する複数の撹拌機付きユニット体10とから形成し、給水部35を門型フレーム12に設けたので、給水のためのスペースを確保することなく、撹拌機付きユニット体10を装着するための門型フレーム12を利用して、撹拌機8の間に適切にかつ合理的に給水部35を設置することができる。詳細には、混合材料の流下方向に沿って、混合材料を撹拌する撹拌機8前方で加水できて、加水した混合材料を有効かつ効率的に撹拌機8で撹拌できると共に、給水部35を、回転駆動される撹拌機8の邪魔にならない位置に合理的に配設することができる。   Further, the mixing cylinder portion 2 includes a bottom portion 11 that guides the flow of the mixed material, and a plurality of gate-type frames 12 that are disposed in a direction across the bottom portion 11 with an interval in the flow direction of the mixed material. A plurality of parts 9, a stirrer 8, and a motor 29 for driving the stirrer 8, which are detachably mounted between the portal frame 12 of the main body part 9 and cover the bottom part 11 to form a conveyance path P. Since the water supply unit 35 is provided in the gate-type frame 12, the gate-type frame for mounting the unit body 10 with the agitator without securing a space for water supply is formed. 12, the water supply part 35 can be installed between the stirrer 8 appropriately and rationally. Specifically, along the flow direction of the mixed material, water can be added in front of the stirrer 8 that stirs the mixed material, and the mixed material that has been added can be effectively and efficiently stirred by the stirrer 8. It can be rationally arranged at a position that does not interfere with the agitator 8 that is rotationally driven.

また、混合用筒部2が搭載される支持架台37と、支持架台37に基端が回転不能に固定されると共に先端が混合用筒部2上端側に回転自在にピン結合された固定式固定長ピラー38と、支持架台37に一端が回転自在にピン結合されると共に他端が混合用筒部2に回転自在にピン結合され、混合用筒部2の傾斜角度を調整するために伸縮作動される可変長ピラー40とを備える、もしくは固定式固定長ピラー38に代えて、支持架台37に基端が回転自在にピン結合されると共に先端が混合用筒部2上端側に回転自在にピン結合された傾倒式固定長ピラー38及び支持架台37と混合用筒部2下端側それぞれに両端がピン結合された支持ピラー39を備えたので、背景技術とは異なり、傾動される混合用筒部2の回転端をその上端(ホッパ5側)に設定することができ、傾斜角度を調整しても、混合用筒部2の上端位置の移動量を小さく抑えることができる。   Also, a support frame 37 on which the mixing cylinder portion 2 is mounted, and a fixed type whose base end is fixed to the support frame 37 so as not to rotate and whose tip is rotatably connected to the upper end side of the mixing cylinder portion 2. One end is rotatably pin-coupled to the long pillar 38 and the support frame 37, and the other end is rotatably pin-coupled to the mixing cylinder 2. The telescopic operation is performed to adjust the inclination angle of the mixing cylinder 2. Or, instead of the fixed fixed-length pillar 38, the base end is rotatably coupled to the support frame 37 and the distal end is rotatably pinned to the upper end side of the mixing cylinder 2 Unlike the background art, the mixing cylinder portion to be tilted is provided with the tilted fixed-length pillar 38 and the support frame 37 which are coupled to each other and the support pillar 39 having both ends pin-coupled to the lower end side of the mixing cylinder portion 2. 2 end of rotation Can be set to the side), be adjusted inclination angle, it is possible to reduce the amount of movement of the upper end position of the mixing tube portion 2.

これにより、ホッパ5に混合材料を投入する搬入装置4の位置調整がほとんど不要、必要であっても僅かであって、材料投入操作に支障を生じることを防止することができる。従って、混合用筒部2の傾斜角度を変更する必要が生じても、容易かつ短時間で復旧することができる。   Thereby, the position adjustment of the carrying-in apparatus 4 which inputs the mixed material into the hopper 5 is almost unnecessary and even if necessary, it is possible to prevent the material input operation from being hindered. Therefore, even if it is necessary to change the inclination angle of the mixing cylinder portion 2, it can be easily and quickly restored.

また、固定長ピラー38を固定式としてこれにより混合用筒部2を支持する場合には、支持ピラー39の設置が不要で、構造を簡単化することができる。他方、支持ピラー39を設置することで、固定長ピラー38を傾倒可能に構成することができ、混合用筒部2の姿勢を自由度高く調整することができる。   Further, when the fixed-length pillar 38 is fixed and the mixing cylinder 2 is supported thereby, the installation of the support pillar 39 is unnecessary, and the structure can be simplified. On the other hand, by installing the support pillar 39, the fixed-length pillar 38 can be tilted, and the attitude of the mixing cylinder portion 2 can be adjusted with a high degree of freedom.

また、支持ピラー39を備えることにより、傾倒式固定長ピラー38、混合用筒部2及び支持架台37とともに四角形リンクを形成することができ、これにより可変長ピラー40を、傾倒式固定長ピラー38とともに支持架台37に同軸で一括してピン結合することができる(第1ブラケット41参照)ので、これらピラー38,39,40等の取付スペースをコンパクト化できると共に、取付作業を簡便化することができる。   Further, by providing the support pillar 39, a rectangular link can be formed together with the tilting fixed length pillar 38, the mixing cylinder 2 and the support frame 37, whereby the variable length pillar 40 can be connected to the tilting fixed length pillar 38. At the same time, it can be pin-coupled to the support frame 37 coaxially and collectively (see the first bracket 41), so that the mounting space for these pillars 38, 39, 40, etc. can be made compact and the mounting work can be simplified. it can.

In the above embodiment, the unit body 10 with a stirrer is mounted between all the portal frames 12, but as shown in FIG. 17, instead of the unit body 10 with a stirrer, You may make it attach the blank unit body 50 which is not equipped with the stirrer and the motor to an appropriate position so that attachment or detachment is possible. In the illustrated example, a blank unit body 50 is attached to the lowermost end of the mixing cylinder portion 2. The blank unit body 50 is composed of the pair of side plates 22a and the top plate 22b. Like the unit body 10 with a stirrer, the blank unit body 50 is connected to the connecting flange portions 13 and 18 of the main body portion 9 via the mounting flange portions 23 and 24. Be joined. The blank unit body 50 is used for adjusting the stirring condition. If necessary, the blank unit body 50 may be replaced with a unit body with a stirrer 10 as shown in FIG. 18 instead. The replacement work is performed by a unit body replacement process by the maintenance facility 43.

このように本体部9には、少なくとも1つの撹拌機付きユニット体10に代えて、底部11を覆って搬送通路Pを区画形成するブランクユニット体50が門型フレーム12間に着脱自在に装着されるので、必要撹拌能力に応じて、撹拌機付きユニット体10の設備個数を変更することができる。すなわち、撹拌能力が十分である場合には、撹拌機付きユニット体10の撹拌機が搬送通路Pにあると排出の妨げとなるので、当該撹拌機付きユニット体10に代えて、ブランクユニット体50を組み付けることが好ましく(モータ無しの省エネ構造となる)、撹拌能力を向上する場合には、ブランクユニット体50に代えて、撹拌機付きユニット体10を組み付けて現地採取土砂混合装置1を構成すれば良く、このように装置構成に余地を与えることができ、フレキシビリティを向上できて、効率よく混合材料の混合撹拌を行うことができる。   In this way, instead of at least one unit body 10 with a stirrer, a blank unit body 50 that covers the bottom portion 11 and defines the conveyance path P is detachably mounted between the portal frame 12 on the main body 9. Therefore, the number of facilities of the unit body 10 with a stirrer can be changed according to a required stirring capacity. That is, when the stirring ability is sufficient, the stirrer of the unit body 10 with a stirrer is in the transport path P, and thus discharge is hindered. (It becomes an energy-saving structure without a motor), and in the case of improving the stirring ability, instead of the blank unit body 50, the unit body 10 with a stirrer is assembled to constitute the locally collected soil mixing apparatus 1. In this way, room can be given to the apparatus configuration, flexibility can be improved, and mixing and stirring of the mixed material can be performed efficiently.
