Description

  The present invention relates to a dust collection vehicle including a dust storage box in which dust is stored, and a dust input box that is connected to a rear opening of the dust storage box and is equipped with a dust loading device. .

  Conventionally, as a garbage collection vehicle, for example, as described in Patent Documents 1 and 2 below, a dust input box equipped with a dust loading device can be tilted at the rear opening of a dust storage box mounted on a chassis. It is known that a discharge plate is provided in a dust container box so as to be movable in the front-rear direction of the vehicle body via a discharge cylinder. By moving the discharge plate in the front-rear direction of the vehicle body via the discharge cylinder, the volume of the dust storage space in which the dust in the dust storage box is loaded can be increased or decreased.

  In the refuse collection vehicle described in Patent Documents 1 and 2, the volume of the dust storage space is increased by automatically moving the discharge plate forward sequentially in accordance with the dust loading by the dust loading device. It is designed to be housed in a dust storage box while compressing. Further, when discharging the dust to the outside, the dust is thrown out by tilting the dust input box upward and moving the discharge plate to the rear with the rear portion of the dust storage box opened.

  However, when the dust collecting vehicle of Patent Documents 1 and 2 loads a bulky dust such as a cardboard into a dust storage box by a dust loading device, the dust is difficult to compress because of the structure of the bulky dust such as a cardboard. In some cases, it tends to be concentrated near one side in the space, or it is likely to gather near the center. In such a case, when loading a bulky dust such as a corrugated cardboard into the dust storage box by the dust loading device in the dust collection vehicle of Patent Documents 1 and 2, the other of the dust storage boxes in the dust storage space. In some cases, there is a case where the discharge plate is moved to the front of the vehicle body to enlarge the volume of the dust storage space in a state where a gap is formed near the side surface or both side surfaces. That is, after moving the discharge plate to the forefront of the vehicle body and expanding the dust storage space in the dust storage box to the maximum, it is difficult to load more than a certain amount of dust even though there is still room in the dust storage space Therefore, there is a case where the dust cannot be efficiently accommodated in the dust accommodating space (the dust accommodating space cannot be effectively used).

Each deck guide portion 12b is formed in a straight line, and an inclination angle with respect to the left-right direction is set to about 45 degrees, for example. Each deck guide portion 12b protrudes from the surface of the deck 7, but the protruding amount is set to a size that does not interfere with the lower end of the discharge plate 6 (for example, about 3 mm to 5 mm). Here, as a modification, the rail portion 12a may not be provided. Moreover, the rail part 12a and the deck guide part 12b do not need to be connected. Further, the rail portion 12a may be provided at any position on the deck 7 as long as the rail portion 12a can be guided to the deck guide portion 12b.

  The stiffener 12B has the same configuration as the stiffener 12A, but is provided on the deck 7 on the inner side of the stiffener 12A (the central side of the dust container 2), and is a pair of stiffeners 12A.

  By these stiffeners 12A and 12B, the convection of the dust in the dust container 2 is directed from the center in the dust container 2 to the left and right side surfaces. Therefore, the stiffeners 12A and 12B allow the thrown-in dust to be distributed in both directions so as not to be concentrated near one side in the dust-receiving space 2a or to be gathered only in the center. It will be accommodated in the box 2 (dispersion effect by the stiffeners 12A, 12B). The stiffeners 12A and 12B here may be either a pair, or may be configured such that similar stiffeners are provided. Further, the arrangement position of the stiffeners is not limited to the case similar to the stiffeners 12A and 12B, and may be arranged at any position on the deck 7 as long as the same effects as the stiffeners 12A and 12B are obtained.

  On the inclined surface 6b of the discharge plate 6, a pair of stiffeners (guide portions) composed of a strip plate member, a square pipe, or a cross-sectional mountain-shaped member that guides the loading of the dust into the dust container 2 by the dust loading device 30. ) 13A and 13B are provided symmetrically with respect to the center of the dust container 2. More specifically, in the stiffener 13A, a pair is formed in a substantially square shape so as to extend from the bottom surface side of the dust container box 2 to the upper part or the side surface direction of the dust container box 2 along the inclined surface 6b of the discharge plate 6. Is provided. Each stiffener 13A is formed in a straight line, and the inclination angle with respect to the horizontal deck surface 7 is set to about 45 degrees, for example. Further, the upper end of each stiffener 13 </ b> A is provided at a height position of about 1/3 from the lower end of the discharge plate 6 with respect to the total height of the discharge plate 6. Each stiffener 13A protrudes from the inclined surface 6b, and the protrusion amount is set to about 30 mm to 80 mm, for example. The stiffener 13B has the same configuration as that of the stiffener 13A. However, the stiffener 13B is provided on the inclined surface 6b inside the stiffener 13A (the center side of the dust container 2), and is a pair of stiffeners 13A. The stiffener spacing is narrow.

  By these stiffeners 13A and 13B, the convection of the dust in the dust container 2 that has reached the discharge plate 6 is directed from the center in the dust container 2 to the upper side of the left and right side surfaces in the dust container 2. ing. Therefore, the dust that has been input by the stiffeners 13A and 13B and has reached the discharge plate 6 is not concentrated in the vicinity of one side surface in the dust accommodating space 2a, and is not collected in the center. To be housed in the dust container 2 (dispersion effect by the stiffeners 13A and 13B). Further, in the stiffeners 13A and 13B, the dispersion effect can be further enhanced in combination with the stiffeners 12A and 12B. Here, either one pair of stiffeners 13A and 13B may be used, or a configuration in which similar stiffeners are provided may be employed. Further, the arrangement position of the stiffener on the inclined surface 6b is not limited to the case of the stiffeners 13A and 13B, and the rear surface (substantially vertical surface 6a, inclined surface) of the discharge plate 6 is provided as long as the effects similar to those of the stiffeners 13A and 13B are obtained. It may be disposed at any position of 6b).

<Configuration of the dust box>
As shown in FIG. 1, guide groove members 14 formed of channel steel are laid on both the left and right side walls of the dust box 3 from the front upper part toward the rear lower part also serving as a reinforcing frame. A sliding plate 15 extending in the entire lateral width direction is accommodated in the dust box 3. Guide rollers 16 are rotatably provided above and below the left and right side edges of the sliding plate 15. These guide rollers 16 are fitted along the inner wall of the guide groove member 14 so as to roll freely.

  Boss portions 17 are provided at the left and right end portions of the upper rear surface of the sliding plate 15. A sliding plate support shaft 18 is inserted through the boss portion 17. 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 FIG. 3 and FIG. 4, a stiffener 23 is formed on the front surface of the compression plate 21 so as to have a mountain-shaped cross section and a top portion having a pointed shape, and the top portion is formed in a sawtooth shape. A plurality of stiffeners 24 are alternately provided in the width direction. Here, the stiffener 23 is formed larger than the stiffener 24, but is not limited thereto.

  Further, as shown in FIGS. 3 and 4, on the front side of the lower end of the compression plate 21, below the stiffener 23 and the stiffener 24, the cross section is a mountain shape and the top has a pointed shape. A plurality of stiffeners 25 are provided. The stiffener 25 is disposed so as not to overlap the longitudinal direction of the stiffener 23 and the longitudinal direction of the stiffener 24. When the compression plate 21 is operated, the stiffeners 23, 24, 25 are loaded into the dust storage box 2 while reliably crushing the dust such as cardboard, and so as not to bite into the dust and cause it to slide down. It is possible.

<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 corrugated cardboard, the stiffeners 23, 24, 25 provided on the front surface of the compression plate 21 will surely crush and bite the dust and cause the dust to slide down. The dust storage space 2a is loaded from the rear opening 4 while avoiding this. 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 being efficiently crushed, the stiffeners 12A and 12B of the deck 7 and the stiffeners 13A and 13B of the discharge plate 6 cause the dust to be concentrated in the vicinity of one side surface in the dust accommodating space 2a or only in the central portion. It will not be trapped and will be distributed in both sides. 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 portion 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 continuously after being placed on the substantially parallel rail portion 12a It becomes easy to flow in the direction of the wall surface in the refuse storage box 2 on the deck guide part 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 embodiment of the present invention has been described above, but only a specific example is illustrated, and the present invention is not particularly limited. The specific configuration and the like can be appropriately changed in design. Further, the actions and effects described in the embodiments of the invention only list the most preferable actions and effects resulting from the present invention, and the actions and effects according to the present invention are described in the embodiments of the present invention. It is not limited to what was done.

  For example, the stiffeners 12A and 12B of the deck 7 and the stiffeners 13A and 13B of the discharge plate 6 may be a pair of left and right curved and substantially square-shaped stiffeners 32 and 33 as shown in FIG. . That is, it is arranged in a substantially square shape so that the convection of the dust loaded by the dust loading device 30 is directed from the central portion in the dust container 2 to the left and right side surfaces, and has the same effect as the above embodiment. If so, the stiffeners 32 and 33 may have any shape. Further, a plurality of pairs of stiffeners 32 and 33 may be provided.

  Further, the configurations of the stiffeners 12A and 12B of the deck 7 and the stiffeners 13A and 13B of the discharge plate 6 in the above-described embodiment can be applied to a dust collection vehicle including a rotary dust loading device.

  The distal ends of a pair of left and right pushing cylinders 28 are connected to the distal end of the extending portion 26b. The pushing cylinder 28 has a base end rotatably supported by a charging box support pin 53a. By the expansion and contraction operation of the pushing cylinder 28, the pushing plate 26 swings in the front-rear direction of the chassis 51 around the central axis 26a.

  The rotating plate 27 is provided below the push plate 26. The rotating plate 27 has a rotating shaft 27a as a rotation center in the vicinity of the lower end of the pushing plate 26, and rotates around the rotating shaft 27a along the bottom wall 29 formed in a substantially semicircular cross section of the dust throwing box 53. It is configured as follows. Further, one of the rotating shafts 27a is drivingly connected to a motor capable of rotating in the forward and reverse directions via a speed reduction mechanism, and rotates in the forward and reverse directions in synchronization with the motor in a state where the torque is increased by the motor. It is configured.

  In the rotary dust loading device 40 having such a configuration, the dust put into the dust throwing box 53 through the dust throwing port 55 is rotated forward by the rotating plate 27 (in FIG. 6, around the rotating shaft 27a). And the tip of the rotating plate 27 is lifted up to the corresponding position on the lower edge of the rear opening 54.
