Front and rear load cells L are provided on the front, rear, left and right between the upper subframe 3 and the lower subframe 2 to measure the weight of the packing box B.

As shown in FIG. 2, at the rear end of the packing box B, at the central portion of the floor board 20, a discharge port 24 for the cargo, that is, the fine particles G is opened. A pair of left and right guide plates 25, 26 are provided in the rear half of the packing box B, and are tapered obliquely from the left and right side plates 16, 17 toward the discharge port 24. These guide plates 25, 26 are It is welded to the floor plate 20 of the packing box B. An end plate 27 is connected to the rear edges of the left and right guide plates 25 and 26 . The end plate 27 is provided with a vertically elongated residual amount confirmation window 29 covered with a transparent acrylic plate 28 .

As shown in FIG. 1, on the floor plate 20 of the packing box B, a rotary valve 30 is provided at the left-right central portion of the rear portion. The fine granules G contained in the packing box B are guided by the left and right guide plates 25, 26 and guided to the rotary valve 30, and the outer sides of the left and right guide plates 25, 26 are dead spaces. The rotary valve 30 is bolted to the left and right guide plates 25 and 26 so as to be positioned above the floor plate 20 of the packing box B. It is open so that the fine particles G in the packing box B can easily flow. As shown in FIG. 5, the rotating direction of the rotary shaft 32 of the rotary valve 30 is counterclockwise (the direction of the arrow in FIG. 5). are arranged radially, and the fine particles G can be transported together with air to the phase mixer 40 described later.

As shown in FIG. 5, among the plurality of blades 35 of the rotary valve 30, the blade 35i on the loading port side (the front side of the packing box B) is rotated toward the floor plate 20 of the packing box B and finely Since the granules G are rotated downward (in the direction of their own weight) while being rotated, the force for rotating the blades 35 can be reduced compared to the rotation in the upward direction.

As shown in FIG. 2, the exhaust port 33 of the rotary valve 30 is connected to a phase mixer 40 for uniformly mixing the fine particles G with the carrier air. This phase mixer 40 is attached to the left-right central portion of the rear edge of the packing box B and arranged behind the rotary valve 30 , and its inlet is connected to the discharge port 33 of the rotary valve 30 . The exit of the phase mixer 40 is connected to upper and downstream delivery pipes 41a and 41b, the upstream delivery pipe 41a is connected to an upstream discharge hose 43 connected to the blower 11, and the downstream delivery pipe 41b. is connected to a downstream discharge hose 44 communicating with the outside. The blower 11 is driven via a drive motor 9 (hydraulic motor) by the running engine of the vehicle V for transporting fine particles, and the downstream discharge hose 44 is connected via a joint 45 to a silo or the like installed on the ground. is connected to the storage container Ca. The fine particles G transferred to the phase mixer 40 by the rotation of the rotary valve 30 can be easily and efficiently transported to a desired location by the downstream side discharge hose 44 together with the conveying air. G does not clog the rotary valve 30, the phase mixer 40 and the hoses 43, 44.

The phase mixer 40 is attached to the left-right central portion of the rear edge of the packing box B and arranged behind the rotary valve 30, so that when the packing box B is dumped rearward as shown in FIG. Since the connection between the container 40 and the discharge hose 43 is offset so as to be below the packing box B, the fine particles G that have fallen to the bottom of the phase mixer 40 are easily discharged from the discharge hoses 43 and 44. As a result, the fine grains G as cargo do not remain in the phase mixer 40 .

In other words, the lower end of the connecting portion (pipe 41a in FIG. 5) is offset so as to be positioned below the lower end of the discharge port 33 in a non-dumping posture. In the present embodiment, the lower ends are aligned horizontally, but the lower end of the connecting portion may be positioned below the lower end of the discharge port 33 .

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 downward from the packing box B, and the upstream end of a communication passage 47 is connected to the downstream end of the hose 46 through a joint 48. , the connecting passage 47 traverses under the packing box B and is connected to the flexible upstream discharge hose 43 via a joint 48 at its downstream side. As shown in FIG. 7, the discharge hose 43 traverses between the floor plate 20 of the packing box B and the upper subframe 3 to reach the rear portion of the packing box B, and passes through the floor plate 20 of the packing box B. It reaches above the floor plate 20 of the packing box B through a fixed pipe (elbow pipe) 49 provided, extends laterally above the floor plate 20, and is connected to the phase mixer 40 at its downstream end. The floor penetrating portion of the discharge hose 43 is the plate thickness portion of the floor plate 20 . A plate thickness portion of the floor plate 20 may be used as a fixed pipe.

As shown in FIG. 3, in a side view of the packing box B, the penetrating portion a of the floor plate 20 of the downstream discharge hose 43 and the tilting center b of the dumping hinge pin 6 of the packing box B are arranged to overlap in the vertical direction. do. As a result, the vertical displacement of the downstream discharge hose 43 can be reduced between the traveling posture (laying down posture) and the dumping posture (tilting posture) of the packing box B. Although the center of the penetrating portion overlaps with the center of the hinge, portions other than the center of the penetrating portion may overlap with the center of the hinge.

A downstream discharge hose 44 connected to the downstream side of the phase mixer 40 extends laterally along the rear edge of the packing box B and extends downward along 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 connected via a joint 45 to a container Ca installed on the ground.

The transportation vehicle V for the fine granules G drops the fine granules G, such as pellets, into the packing box B in the flattened position by opening the loading lids 22 and 23 . When the floor plate 20 is tilted by the dumping operation of the packing box B over the angle of repose of the fine grains G, the fine grains G in the packing box B move to the rear of the packing box B. At this time, the inclination of the floor plate 20 of the packing box B and the pair of guide plates 25 and 26 allow the fine particles G in the packing box B to be automatically moved to the outlet 24 and supplied to the rotary valve 30 . Further, by driving the blower 11, air is blown into the discharge hoses 43 and 44 by wind power through the phase mixer 40, and the fine particles B can be blown away from the rotary valve 30 and the phase mixer 40 and pumped. The body G does not clog the discharge hoses 43, 44. - 特許庁
