The container 5 has inclined surfaces 5c that are inclined downward toward the outer side in the vehicle width direction on both the left and right sides, and the center of the left and right is a flat surface 5d, which has a so-called cross-sectional shape. The rear surface of the container 5 is formed as a tailgate 7 whose upper end is pivotally supported by an upper pivot 9 and can be opened rearward. A horn handle 10 for sealing the tailgate 7 is provided at four positions on the rear surface, top, bottom, left, and right. By tightening the horn handle 10, the rear opening of the container 5 is sealed by the tailgate 7. ing.

  As shown in FIG. 1, the loading / unloading device 6 is pivotally supported at a rear end portion of the subframe 4 so as to be tiltable backward around a pivot 11, and is disposed on a rear portion of the subframe 4. The tilting frame 12 includes a substantially L-shaped cargo handling frame 14 that is connected around the support portion 13 at the front of the tilting frame 12 so as to be raised and lowered.

  The cargo handling frame 14 includes a guide member 16 and a substantially L-shaped L-shaped arm 17 having a proximal end inserted into the guide member 16, and the L-shaped arm 17 is expanded and contracted by a slide cylinder 18. The guide member 16 is configured to expand and contract. An engagement hook 15 that can be engaged with the engagement pin 5 a of the container 5 is provided at the tip of the L-shaped arm 17. Between the guide member 16 and the front position of the sub-frame 4, a tilt cylinder 19 is rotatably supported via a pivot (not shown).

-Method of collecting dewatered cake in container-
Next, for example, a method of dewatering sludge generated in a sludge storage tank (not shown) in a sewage treatment plant and collecting the dewatered cake in the container 5 will be described.

  First, as shown in FIG. 5, as a preparatory step, a dehydrator 35 is prepared as a waste disposal machine that dehydrates sludge collected from the sludge storage tank and discharges the dehydrated cake from the discharge port 35a. The dehydrator 35 has an agitation motor 35b that agitates sludge such as sewage, human waste, and industrial wastewater that flows in, and the agitation motor 35b agitates the mixed polymer flocculant. Further, a compression roller (not shown) is provided inside, and sludge is dewatered by this compression roller. The gas in the dehydrator 35 can be sucked from the exhaust port 35c.

  An intake blower 31 for sucking air from the intake duct 30 and the container 5 are prepared, and at least one of the three deodorizing ports 21 is opened and the intake duct 30 is connected. Also connected to the exhaust port 35c of the dehydrator 35.

  Next, in the dehydration step, sludge is poured into the dehydrator 35, and the agitation motor 35b is agitated with the polymer flocculant and dehydrated with the compression roller.

  Next, in the charging step, the charging port opening / closing lid 20a of one charging port 20 of the container 5 is opened, and the dehydrated cake is dropped from the discharging port 35a of the dehydrator 35 and charged.

  In the meantime, in the intake process, the air inside the container 5 is sucked from the intake duct 30. For this reason, since the gas generated in the container 5 is inhaled, the spread of malodor is prevented.

  In addition, an inspection process is performed as appropriate, and the inspection port opening / closing lid 22a of the inspection port 22 is opened to check the state of the dehydrated cake inside the container 5. Since the inspection port opening / closing lid 22a of the inspection port 22 formed on the inclined surface 5c and having a lower front is opened, it is easy to open and close and to easily look inside the container 5. Also at this time, the spread of malodor is suppressed by the inhalation action of the internal gas.

  Next, in the inspection process, when it is determined that the waste cannot be charged, the container 5 is moved, and the dehydrated cakes are sequentially charged from the discharge port 35 a of the dehydrator 35 to another input port 20 arranged in the longitudinal direction of the container 5. . That is, when a dehydrated cake is charged into one charging port 20, the dehydrated cake is accumulated only in the vicinity of the charging port 20 because the fluidity of the dehydrated cake is low. Next, by putting the dehydrated cake into another charging port 20, the dehydrated cake is accumulated in the vicinity of the charging port 20. In this way, the dehydrated cake is spread over the entire interior of the container 5 by sequentially loading the dehydrated cake into the separate inlets 20.

  Next, in the inspection process, when it is determined that the inside of the container 5 is filled with waste, the collection operation is stopped, and the container 5 is loaded onto the subframe 4 by the loading / unloading device 6 of the container handling vehicle 1 as shown in FIG. To do. Since the container 5 is easily loaded or unloaded between the vehicle body frame 2 and the ground by the cargo handling frame 14 of the container cargo handling vehicle 1, the dewatered cake can be collected and transported smoothly.

  Subsequently, it moves to a waste disposal site and performs a discharge process in the waste disposal site. First, the tailgate 7 is opened and the tilting cylinder 19 is extended in a state in which the rotation of the load handling frame 14 around the support portion 13 with respect to the tilt frame 12 is prohibited, and the tilt frame 12 and the load handling frame as shown in FIG. The contents in the container 5 are discharged by tilting the container 14 and tilting the container 5 on the vehicle body frame 2.

  Further, after the discharging process, the inside of the container 5 can be cleaned and inspected by opening the tailgate 7.

  When the container 5 is lowered from the mounted state shown in FIG. 1, first, as shown in FIG. 7, the slide cylinder 18 is contracted to store the L-shaped arm 17 in the guide member 16, and further tilted. The cylinder 19 is extended to move the cargo handling frame 14 backward. As a result, the cargo handling frame 14 rotates (tilts) around the support portion 13 with respect to the tilting frame 12, and the container 5 slides on the guide roller 11a by its own weight and is lowered to the ground. On the other hand, mounting the container 5 on the subframe 4 is performed by performing the operation opposite to the above operation.

-Effect of the embodiment-
Therefore, according to the present embodiment, the dehydrated cake from which sludge has been dehydrated is introduced into the inlet 20, the air in the container 5 is sucked from the deodorizing port 21, the inside of the inspection port 22 is opened, the inside of the container 5 is inspected, and the tailgate 7 The dewatered cake inside the container 5 is discharged to the outside of the container 5 so that sludge is reliably collected in the container 5 without causing bad odors to drift around. After the collection, the dewatered cake is efficiently discharged. can do.
