図２に示すように、左右方向に長い長方形状に形成される、遮音型の機器収容筐１０内には、ブロア１１、その駆動モータ（油圧モータ）９よりなる油圧駆動装置Ｄ、その他の機器が収容される。 As shown in FIG. 2, a blower 11, a hydraulic drive device D including a drive motor (hydraulic motor) 9 for the blower 11, and other devices are formed in a sound insulation type device housing casing 10 formed in a rectangular shape that is long in the left-right direction. Is housed.

機器収容筐１０の外部には、油圧駆動装置Ｄを操作し得る操作部５２が設けられ、その操作部５２と油圧駆動装置Ｄとの移動連結部５３は前記機器収容筐１０に開口した通し穴５５を貫通しており、機器収容筐１０の外部に設けた防音カバー５７には、前記通し穴５５を通して発散する騒音の指向方向に対向する防音壁５８が設けられている。 An operation unit 52 that can operate the hydraulic drive device D is provided outside the device housing case 10, and a moving connection portion 53 between the operation unit 52 and the hydraulic drive device D is a through hole opened in the device housing case 10. A soundproof wall 57 that penetrates 55 and is provided outside the device housing case 10 is provided with a soundproof wall 58 that faces in the direction of the direction of the noise emitted through the through hole 55.

前記騒音の指向方向とは、油圧駆動装置Ｄのうち、音源となるブロア１１や油圧モータ９から通し穴５５へと結んだ直線の方向である。その直線を遮るように防音壁５８を設けている。なお、また音源の発生元は、動く部品（スクリュやスプール）および流体（油や空気）が通る流路である。このため、音源の発生元から通し穴５５へと結んだ直線の方向が指向方向である。指向方向は、例えば発生元である動く部品の中心と通し穴５５の中心とを結んだ直線でもよいし、動く部品の端と通し穴の端を結んだ直線でもよい。また、流路の内壁から通し穴の中心や端を結んだ直線でもよい。防音壁５８は直線を遮っていればよく、傾いていてもよい。 The direction of the noise is a direction of a straight line connecting the blower 11 or the hydraulic motor 9 which is a sound source in the hydraulic drive device D to the through hole 55. A soundproof wall 58 is provided so as to block the straight line. The source of the sound source is the flow path through which moving parts (screws and spools) and fluids (oil and air) pass. Therefore, the direction of the straight line connecting the sound source to the through hole 55 is the directivity direction. The directivity direction may be, for example, a straight line connecting the center of the moving part that is the generation source and the center of the through hole 55, or a straight line connecting the end of the moving part and the end of the through hole. Further, it may be a straight line connecting the center or end of the through hole to the inner wall of the flow path. The soundproof wall 58 only needs to block a straight line and may be inclined.

防音カバー５７は、操作部５２と前記油圧駆動装置Ｄとの連結部を被覆している。防音カバー５７には、その上面に前記操作部５２を通すための長孔５９が開口され、その長孔５９から操作部５２の長手方向に延びる延長部５７1 が設けられる。 The soundproof cover 57 covers the connecting portion between the operating portion 52 and the hydraulic drive device D. The soundproof cover 57 is an elongated hole 59 for passing the operating portion 52 on its upper surface is opened, the extension 57 1 is provided extending in the longitudinal direction of the operation unit 52 from the elongated hole 59.

前記延長部５７1 は、防音カバー５７の内方に延長させるか（図９、実線に示す）、あるいは、防音カバー５７の外方に延長させてもよい（図９、鎖線に示す）。 The extension portion 57 1 are either prolong the inside of the soundproof cover 57 (FIG. 9, shown in solid line), or may also be extended to the outside of the soundproof cover 57 (FIG. 9, shown in dashed line).

図８、９に示すように、機器収容筐１０の、車両Ｖの進行方向左側に設けられる仕切壁５０には、操作フレーム５１が設けられる。この操作フレーム５１には、荷箱Ｂを上げ、下げ操作する操作部すなわち操作レバー５２が設けられる。この操作レバー５２は、通常のように、荷箱Ｂをダンプ上げ、ダンプ下げおよび中立位置に回動操作できるように、操作フレーム５１に回動可能に設けられ、移動連結部５３を介して油圧駆動装置Ｄに連結されている。前記移動連結部５３は、前記仕切壁５０に開口した通し穴５５を貫通して、外部に延出されている。 As shown in FIGS. 8 and 9, an operation frame 51 is provided on a partition wall 50 provided on the left side of the device housing casing 10 in the traveling direction of the vehicle V. The operation frame 51 is provided with an operation section for raising and lowering the luggage box B, that is, an operation lever 52. The operation lever 52 is rotatably provided on the operation frame 51 so that the cargo box B can be dumped up, dumped down and rotated to a neutral position as usual. It is connected to the drive device D. The movement connecting portion 53 extends through the through hole 55 opened in the partition wall 50 and extends to the outside.

而して、機器収容筐１０内に発生する作動音は、前記通し穴５５を通して外部に伝播し、この作動音が微細粒体の搬送時の作動騒音の原因となるが、この騒音は、以下に述べる防音カバー５７により低減される。機器収容筐１０の仕切壁５０の外面に固着される防音カバー５７は、前記通し穴５５より発散する騒音の指向方向に対向する防音壁５８を備えており、機器収容筐１０より発生する騒音は、防音カバー５７により低減することが可能である。前記防音カバー５７内には前記操作レバー５２の下半部が収容されており、その上半部は、防音カバー５７の上面に開口した長孔５９を通して外部に延出されている。 Thus, the operating noise generated in the equipment housing 10 propagates to the outside through the through hole 55, and this operating noise causes operating noise when the fine particles are conveyed. It is reduced by the soundproof cover 57 described below. The soundproof cover 57 fixed to the outer surface of the partition wall 50 of the device housing case 10 is provided with a soundproof wall 58 facing in the direction of the noise emitted from the through hole 55. The soundproof cover 57 can reduce the noise. The lower half of the operation lever 52 is accommodated in the soundproof cover 57, and the upper half of the operation lever 52 extends to the outside through a long hole 59 opened in the upper surface of the soundproof cover 57.

これにより、操作レバー５２を操作中の作業者がいる方向にもれる騒音が抑制されるため、他の作業者からの合図などを聞き取りやすい。 As a result, noise that leaks in the direction of the worker who is operating the operation lever 52 is suppressed, and thus it is easy to hear a signal or the like from another worker.

Then, the fine particles G transferred to the phase mixer 40 by the rotation of the rotary valve 30 can be easily and efficiently transferred to a desired place from the downstream discharge hose 44 together with the transfer air, that is, the load, that is, the fine particles. G is not blocked in the rotary valve 30, the phase mixer 40, and the hoses 43 and 44.

混相器４０は、荷箱Ｂの後縁の左右中央部に取り付けられてロータリバルブ３０の後方に配置されているので、図５に示すように、荷箱Ｂを後方にダンプさせたとき、混相器４０と吐出ホース４３との接続部は、荷箱Ｂの下方になるようにオフセットされるので、混相器４０の底に落下した、微細粒体Ｇが、吐出ホース４３、４４から吐出されやすくなり、積荷である微細粒体Ｇが混相器４０内に残留することがない。 Since the phase mixer 40 is attached to the left and right central portions of the trailing edge of the luggage box B and arranged behind the rotary valve 30, as shown in FIG. 5, when the luggage box B is dumped backward, Since the connecting portion between the container 40 and the discharge hose 43 is offset so as to be located below the packing box B, the fine particles G dropped to the bottom of the phase mixer 40 are easily discharged from the discharge hoses 43 and 44. Therefore, the fine particles G as a cargo do not remain in the phase mixer 40.

言い換えると、ダンプしない姿勢で接続部（図５において管４１ａ）下端を、排出口３３の下端以下の位置になるようにオフセット。本実施形態では、下端同士を水平方向に一致させているが、接続部下端を排出口３３下端より下方としてもよい。 In other words, the lower end of the connecting portion (the pipe 41a in FIG. 5) is offset so that the lower end of the connecting portion (the pipe 41a in FIG. 5) is positioned below the lower end of the discharge port 33 in a posture of not dumping. In the present embodiment, the lower ends are made to coincide with each other in the horizontal direction, but the lower end of the connecting portion may be below the lower end of the discharge port 33.

図２に示すように、前記ブロア１１の吐出側には、上流側吐出ホース４３が接続される。ブロア１１の吐出口には可撓性のホース４６が接続され、このホース４６は、荷箱Ｂの下方に延長されてその下流端に連絡通路４７の上流端がジョイント４８を介して連通接続され、その連絡通路４７は、荷箱Ｂの下方を縦走してその下流側がジョイント４８を介して可撓性の上流側吐出ホース４３に接続されている。図７に示すように、吐出ホース４３は、荷箱Ｂの床板２０と上部サブフレーム３との間を縦走して荷箱Ｂの後部に達しており、荷箱Ｂの床板２０を貫通して設けられる、固定管（エルボ管）４９を通して荷箱Ｂの底板２０上に達しており、床板２０の上方を横方向に延長されて、その下流端が前記混相器４０に接続されている。吐出ホース４３の床面貫通部とは、床板２０の板厚部分である。その床板２０の板厚部分を固定管とすればよい。 As shown in FIG. 2, an upstream discharge hose 43 is connected to the discharge side of the blower 11. A flexible hose 46 is connected to the discharge port of the blower 11, the hose 46 extends below the packing box B, and the downstream end of the hose 46 is connected to the upstream end of the communication passage 47 through a joint 48. The connecting passage 47 runs vertically below the packing box B, and its downstream side is connected to a flexible upstream discharge hose 43 via a joint 48. As shown in FIG. 7, the discharge hose 43 extends vertically between the floor board 20 of the packing box B and the upper subframe 3 to reach the rear part of the packing box B, and penetrates the floor board 20 of the packing box B. It reaches the bottom plate 20 of the luggage box B through a fixed pipe (elbow pipe) 49 provided, extends laterally above the floor plate 20, and its downstream end is connected to the phase mixer 40. The floor surface penetrating portion of the discharge hose 43 is a plate thickness portion of the floor plate 20. The plate thickness portion of the floor plate 20 may be a fixed tube.

図３に示すように、荷箱Ｂの側面視で、前記下流側吐出ホース４３の床板２０の貫通部ａと、荷箱Ｂのダンプ用ヒンジピン６の傾動中心ｂとが上下方向で重なるようにする。これにより、荷箱Ｂの、走行姿勢（伏倒姿勢）とダンプ姿勢（傾動姿勢）とで下流側吐出ホース４３の上下変位を少なくすることができる。貫通部の中心がヒンジ中心と重なっているが、貫通の中心以外の部分がヒンジ中心と重なってもいてもよい。 As shown in FIG. 3, in a side view of the luggage box B, the penetrating portion a of the floor plate 20 of the downstream discharge hose 43 and the tilting center b of the dump hinge pin 6 of the luggage box B overlap in the vertical direction. To do. Accordingly, the vertical displacement of the downstream discharge hose 43 can be reduced depending on the traveling posture (falling posture) and the dumping posture (tilting posture) of the cargo box B. Although the center of the penetrating portion overlaps with the hinge center, a portion other than the penetrating center may overlap with the hinge center.

混相器４０の下流側に接続される下流側吐出ホース４４は、荷箱Ｂの後縁に沿って横方向に延び、車両Ｖのシャシフレーム１の後縁を下方に延長され、その出口は、車両Ｖの後方に開放され、ジョイント４５を介して地上に設置される収容容器Ｃａに接続される。 The downstream discharge hose 44 connected to the downstream side of the phase mixer 40 extends laterally along the rear edge of the luggage box B and extends downward at the rear edge of the chassis frame 1 of the vehicle V, and its outlet is It is opened to the rear of the vehicle V and is connected via a joint 45 to a storage container Ca installed on the ground.

微細粒体Ｇの搬送車両Ｖは、伏倒位置にある荷箱Ｂ内に、投入蓋２２、２３の開放により、ペレットなどの微細粒体Ｇが荷箱Ｂ内に投下、収容される。荷箱Ｂのダンプ作動による床板２０の、微細粒体Ｇの安息角以上の傾動によれば、荷箱Ｂ内の微細粒体Ｇは、荷箱Ｂの後部に移動する。このとき、荷箱Ｂの底板２０の傾斜および一対のガイド板２５，２６により、荷箱Ｂ内の微細粒体Ｇを排出口２４に自動的に移動させてロータリバルブ３０に供給することができ、さらにブロア１１の駆動により、混相器４０を経て風力により、吐出ホース４３，４４に空気を吹き込んで微細粒体Ｂをロータリバルブ３０および混相器４０から吹き飛ばして圧送することができ、微細粒体Ｇが吐出ホース４３，４４に詰まることがない。 The transport vehicle V of the fine particles G has the fine particles G such as pellets dropped and accommodated in the load box B in the lying position by opening the loading lids 22 and 23. Due to the tilting of the floorboard 20 by the dumping operation of the packing box B over the angle of repose of the fine particles G, the fine particles G in the packing box B move to the rear part of the packing box B. At this time, due to the inclination of the bottom plate 20 of the packing box B and the pair of guide plates 25 and 26, the fine particles G in the packing box B can be automatically moved to the discharge port 24 and supplied to the rotary valve 30. Further, by driving the blower 11, air can be blown into the discharge hoses 43 and 44 by wind force through the phase mixer 40 to blow the fine particles B from the rotary valve 30 and the phase mixer 40 and to feed them by pressure. The discharge hoses 43 and 44 are not clogged with G.
