The sliding plate support shaft 18 is disposed so as to protrude beyond the inside of the dust throwing box 3 beyond the sliding openings 19 formed on the left and right side walls of the dust throwing box 3.

  Further, between the sliding plate support shaft 18 projecting outward from the left and right side walls of the dust input box 3 and the lower part of the dust input box 3, the left and right outer sides of the dust input box 3 are arranged in the inclination direction of the guide groove member 14, respectively. Sliding cylinders 20 arranged along each other are connected to each other. By the expansion / contraction operation of the sliding cylinder 20, the sliding plate 15 reciprocates up and down along the guide groove member 14.

  At the lower end of the sliding plate 15, a compression plate 21 extending across the entire width direction of the dust box 3 is supported via a connecting portion 21b so as to be swingable in the front-rear direction. The tip of the compression plate 21 is slightly bent toward the front. In addition, connecting portions 21 a are projected from the left and right rear surfaces of the compression plate 21. Oscillating cylinders 22 are respectively connected between the left and right connecting portions 21a and the left and right ends of the sliding plate support shaft 18 provided on the upper rear surface of the sliding plate 15. The compression plate 21 swings back and forth by the expansion / contraction operation of the swing cylinder 22.

  As shown in FIGS. 3 and 4, the compression plate 21 includes a first surface 21c provided on one end portion side of the compression plate 21 and an end portion on the opposite side to the one end portion side of the first surface 21c. And a second surface 21d that is inclined at an angle of 90 ° or more on the compression surface side with respect to the first surface 21c. On the first surface 21c, a stiffener (second biting tooth) made of an elongated member laid from the end on one end of the first surface 21c to the end 21e on the second surface 21d. 23 and stiffeners (third biting teeth) 24 made of a long member laid from the substantially central portion of the first surface 21c to the end portion 21e on the second surface 21d side are alternately arranged in the width direction. A plurality are provided. The stiffener 23 and the stiffener 24 have a mountain-shaped cross section and are arranged so that one of the sides is the tip of the pointed portion, and the tip is formed in a saw-tooth shape. Here, the stiffener 23 is formed larger than the stiffener 24, but is not limited thereto.

  As shown in FIGS. 3 and 4, the second surface 21 d protrudes toward the first surface 21 c side from the tangent in the rotational direction of the compression plate 21 so as to bite into the dust.

It is possible to load it in the refuse storage box 2 while preventing it from being left.

<Operation of garbage truck>
When loading dust into the dust container 2 with the dust loading device 30 having the above-described configuration, the discharge cylinder 11 is first extended as shown in FIG. 1 and the discharge plate 6 is disposed at the rearmost position in the dust container 2. Then, dust is thrown into the dust throwing box 3 through the dust throwing opening 5 in a state where both the sliding cylinder 20 and the swing cylinder 22 are extended and the sliding plate 15 is at the lift end position (uppermost position). Then, when a loading instruction is given to the dust loading device 30, the dust loading device 30 is moved from the state shown in FIG. The end position is reached (reversing step (not shown)). Thereafter, the sliding cylinder 20 is retracted, the sliding plate 15 is lowered, and the compression plate 21 is lowered accordingly (lowering step (not shown)). Although not shown, when the compression plate 21 reaches the lowering end position, the swing cylinder 22 is extended to swing the compression plate 21 forward, and the process proceeds to the compression step. Then, when the compression plate 21 swings to the compression end position (compression step), the sliding cylinder 20 is extended to raise the compression plate 21 (upward step (not shown)). When the compression plate 21 reaches the rising end position shown in FIG. 1, the series of loading operations is finished. As a result, the dust loading operation is repeated with each step of reversing, lowering, compressing and ascending the compression plate 21 as one cycle.

  And when the force with which the dust loaded by the dust loading device 30 presses the discharge plate 6 reaches a predetermined value or more, the discharge plate 11 is gradually moved forward by retracting the discharge cylinder 11. By the movement operation of the discharge plate 6, the volume of the dust storage space 2a can be enlarged, and the dust can be loaded into the dust storage box 2 while being compressed. At this time, even if the dust is a bulky dust such as a corrugated cardboard, the stiffeners 23, 24, 25 provided on the front surface of the compression plate 21 reliably crush and bite the dust, and slide the dust off the compression plate. It is loaded into the dust accommodating space 2a from the rear opening 4 while preventing it from being let go. During the loading, the dust in contact with the stiffeners 12A and 12B of the deck 7 and the dust in contact with the stiffeners 13A and 13B of the discharge plate 6 are pushed into the dust containing space 2a by the compression plate 21. However, it is easy to flow separately along the left and right side surfaces in the dust container box 2 along each stiffener. As a result, the dust is dispersed not only in the central portion of the dust container box 2 but also on the left and right side surfaces, and is smoothly accommodated in the dust container space 2a without wasteful gaps.

  On the other hand, when discharging the dust outside, the discharge cylinder 11 is extended in a state where the dust input box 3 is tilted upward and the rear part of the dust storage box 2 is opened, so that the dust container box 2 is positioned in front of the dust storage box 2. The discharge plate 6 to be moved is moved rearward so that the dust stored in the dust storage box 2 can be discharged. At this time, the dust in contact with the stiffeners 13A and 13B of the discharge plate 6 is likely to flow separately along the stiffeners 13A and 13B from the central lower part in the dust container 2 to the upper direction on the left and right side surfaces. At this time, the dust in contact with the stiffeners 12A and 12B of the deck 7 is likely to shift from the side surface of the dust containing box 2 toward the central portion along the stiffeners 12A and 12B. Accordingly, when the discharge plate 6 is moved rearward, the lump of dust loaded in the dust container 2 can be easily broken from the bottom, and the dust in the dust container 2 can be easily discharged. be able to.

  As described above, in the refuse collection vehicle 100 according to the present embodiment, when the dust is loaded into the dust storage box 2 by the dust loading device 30, the stiffeners 23, 24, and 25 of the compression plate 21 ensure that the dust is more reliable than before. By collaborating efficiently, the stiffeners 12A and 12B of the deck 7 and the stiffeners 13A and 13B of the discharge plate 6 cause dust to be concentrated near one side in the dust accommodating space 2a, It is distributed in both sides without gathering together. Thereby, the volume of the dust storage space 2a can be expanded without forming a useless gap in the dust storage space 2a while moving the discharge plate 6 forward. Therefore, the dust can be efficiently stored in the dust storage space 2a, and the amount of dust loaded in the dust storage box 2 can be increased as compared with the conventional case. In addition, by providing a guide member on the inner bottom of the dust container, irregularities are formed on the inner bottom so that dust such as cardboard is not caught in the gap between the inner bottom of the dust container and the lower end of the discharge plate. can do. Furthermore, even when the surface of the dust such as cardboard is wet and the surface resistance is increased, the stiffeners 12A and 12B of the deck 7 and the stiffeners 13A and 13B of the discharge plate 6 are used to remove the dust from the deck 7 and the discharge plate 6. Since it can be made difficult to stick to the surface, it is possible to improve the loading and discharging workability of the dust. As a result, when bulky dust such as cardboard is loaded into the dust storage box 2 by the dust loading device 30, the dust can be efficiently stored in the dust storage space 2a in the dust storage box 2. Moreover, the dust in the dust container 2a can be discharged efficiently.

  In addition, the dust easily slides into the deck guide portion 12b of the stiffener 12A in the dust container 2 through the substantially parallel rail portion 12a, and after being placed on the substantially parallel rail portion 12a, the reverse letter C is continuously formed. It becomes easy to flow in the direction of the wall surface in the dust container 2 by being placed on the guide portion 12b of the mold. Thereby, the loading workability | operativity of a refuse can be improved more. Further, when discharging the dust, the dust placed on the rail portion 12a is easily discharged rearward along the rail portion 12a, so that the dust discharge workability can be further improved. The stiffener 12B has the same effect as the stiffener 12A.

The stiffener 45 is disposed on the second surface 41d so as to be displaced from a virtual plane 46 that includes the longitudinal center line 43a of the stiffener 43 and is orthogonal to the first surface 41c. Further, the stiffener 45 is disposed on the second surface 41d so as to be displaced from a virtual plane 47 that includes the longitudinal center line 44a of the stiffener 44 and is orthogonal to the first surface 41c. During the operation of the compression plate 41, the stiffeners 43, 44, and 45 cooperate to reliably crush dust such as corrugated cardboard, and bite into the dust to cause the dust to slide down from the compression plate 41. It is possible to load it in the garbage storage box while preventing it from straying.

<Modification 2>
In this modification, although it is the structure substantially the same as the said modification 1, it differs in the point which uses the stiffeners 53 and 54 instead of the stiffeners 43 and 44 of the modification 1, Other parts are Since it is the same as that of the said modification 1, description may be abbreviate | omitted.

  Each of the stiffeners 53 and 54 is made of a member that is slightly longer than the stiffeners 43 and 44 of the first modification. In the stiffener 54, the tip is formed in a saw-tooth shape. During the operation of the compression plate 51, the stiffeners 53, 54 and 55 described above collaborate to reliably crush dust such as corrugated cardboard and bite into the dust so that the dust does not slide off the compression plate 51. In this way, it can be loaded into the refuse storage box.
