[0003] [Patent Document 1] Utility Model Registration No. 2576084 Summary of the Invention [Problem to be solved by the invention]

[0004] When attaching the discharge plate cylinder to the garbage collection box, a bracket is welded to the discharge plate, and the discharge plate cylinder is attached to this bracket. However, because there is a dimensional error in the fore-and-aft direction of the vehicle of the discharge plate cylinder relative to the garbage collection box, a spacer was sandwiched between the discharge plate and the bracket to adjust the attachment dimensions. This required welding in two places, between the discharge plate and the spacer and between the spacer and the bracket, which was time-consuming.

[0005] SUMMARY OF THE PRESENT EMBODIMENT An object of the present invention is to provide a garbage collection vehicle in which the number of welding points is reduced when attaching a discharge plate cylinder to a garbage collection box. [Means for solving the problem]

[0006] The present invention is a garbage collection vehicle comprising: a garbage storage box that stores collected garbage inside; and a discharge device for discharging the garbage inside the garbage storage box to the outside through an opening that the garbage storage box has. The discharge device comprises a discharge plate that moves from the front of the vehicle to the rear of the vehicle inside the garbage storage box, pushing garbage toward the opening, a hydraulic cylinder connected to the discharge plate and generating a driving force that moves the discharge plate in the fore-and-aft direction of the vehicle, a discharge plate cylinder having a connecting portion for the connection, and a bracket assembly interposed between the discharge plate and the discharge plate cylinder, the bracket assembly comprising: a cylinder support that supports the connecting portion of the discharge plate cylinder, a bracket base that is separate from the cylinder support and is combined with the cylinder support and fixed to the discharge plate, and a fixing means that is provided across the cylinder support and the bracket base to fix both of them.

[0007] According to the present invention, the mounting dimensions of the discharge plate cylinder in the garbage collection box can be adjusted by using a bracket assembly in which the cylinder support is fixed to the bracket base by a fixing means.

[0008] In addition, the cylinder support has a support portion for positioning the connecting portion of the discharge plate cylinder, and multiple types are available in which the support portion is formed at different positions, and the bracket assembly is formed by combining one type of cylinder support selected according to the dimensional relationship of the discharge plate cylinder to the garbage collection box with the bracket base.

[0009] According to this configuration, the bracket assembly can be constructed by selecting one type of cylinder support suitable for adjusting the mounting dimensions from among multiple types of cylinder supports having different positions for forming the support parts, thereby making it easy to adjust the mounting dimensions of the discharge plate cylinder in the garbage collection box.

[0010] The connecting portion may be a rod-shaped portion protruding from the discharge plate cylinder, and the support portion may be a through hole having a space through which the connecting portion passes.

[0011] According to this configuration, the connecting portion is a rod-shaped portion, and the supporting portion corresponding to this is a through hole, so that the configuration for connecting to the discharge plate is simple. Effect of the Invention

[0012] According to the present invention, the mounting dimension of the discharge plate cylinder in the trash collection box can be adjusted by the bracket assembly, and therefore the number of welding points can be reduced when mounting the discharge plate cylinder to the trash collection box.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS

[0014] An embodiment of a refuse collection vehicle according to the present invention will be described below with reference to Figures 1 to 11. The basic configuration of the refuse collection vehicle is the same as the conventional example shown in Figure 12, so only a rough description will be given. For convenience, the basic configuration will be described using the configuration shown in Figure 12. In the following description, the terms front and back refer to the side of the driver's cab 21 of the refuse collection vehicle 1 as the front side, and the side of the refuse storage box 3 as the rear side.

[0015] The garbage collection vehicle 1 is used to collect garbage and other garbage and transport it to a disposal facility, and is equipped with a chassis 2 having a driver's cab 21, a garbage storage box 3 arranged behind the driver's cab 21 on the chassis 2, a garbage drop box 4 connected to the rear of the garbage storage box 3, a loading device 5 arranged inside the garbage drop box 4 for loading garbage, a discharge device 6 for discharging garbage inside the garbage storage box 3 to the outside, and a control unit (not shown) capable of controlling the loading device 5, the discharge device 6, etc.

[0016] The dust collection box 3 is a box-shaped part for storing collected dust therein, and has an opening 31 that opens toward the rear.

[0017] The trash bin 4 has an input opening 41 that opens rearward at the rear end, and trash is input through the input opening 41 by an operator. Inside the trash bin 4, the bottom 44 has a curved arc shape that is convex downward when viewed from the vehicle width direction. The trash bin 4 also has a lid 42 that opens and closes the input opening 41 by sliding up and down. The trash bin 4 is connected to the trash storage box 3 via a rotating shaft 43 that is provided at the top and extends in the vehicle width direction. The trash bin 4 can rotate around the rotating shaft 43, and this rotation opens and closes the opening 31 of the trash storage box 3. For example, when the trash dump box 4 is in the position shown by the solid line in Figure 12, it closes the opening 31 of the trash storage box 3, and when it is rotated upward to the position shown by the dotted line in Figure 12, it opens the opening 31 of the trash storage box 3, allowing the trash stored in the trash storage box 3 to be discharged to the outside.

[0018] The loading device 5 has a push plate 53 that pushes the garbage thrown in from the throw-in opening 41 into the garbage storage box 3, and is disposed in the garbage throw-in box 4. This loading device 5 is controlled by the control unit. Specifically, the loading device 5 has a pair of guide rails 51 extending along both side walls of the garbage throw-in box 4 and in an inclined direction, a pair of sliders 52 that are slidable (guided) along the guide rails 51, the above-mentioned push plate 53 disposed between the pair of sliders 52, and a pin 54 that connects each slider 52 to the push plate 53. This pin 54 extends in the vehicle width direction, and connects the push plate 53 to each slider 52 so that the push plate 53 can rotate around the pin 54. This push plate 53 is a member that compresses the garbage thrown in the garbage throw-in box 4 and pushes it into the garbage storage box 3.

[0019] The loading device 5 also has a pair of push cylinders (compression drive means) 55 and a pair of press cylinders (push drive means) 56 that drive the push plate 53, and each of the pair of push cylinders 55 and the pair of press cylinders 56 has a cylinder and a piston. Each of the pair of push cylinders 55 is disposed along both side walls in the garbage dump box 4, and each of the pair of press cylinders 56 is also disposed along both side walls in the garbage dump box 4.

[0020] In each push cylinder 55, the cylinder end is connected to the side wall of the trash bin 4, and the piston end is connected to the upper end of the slider 52 (the slider 52 on the corresponding side in the vehicle width direction). When the push cylinder 55 extends, the slider 52 to which the push cylinder 55 is connected moves obliquely upward along the guide rail 51, and when the push cylinder 55 contracts, the slider 52 to which the push cylinder 55 is connected moves obliquely downward along the guide rail 51.

[0021] Moreover, in each press cylinder 56, the cylinder side end is connected to the push plate 53, and the piston side end is connected to the upper end of the slider 52 together with the piston side end of the push cylinder 55. When the pair of push cylinders 55 maintain their length, i.e., when the pistons do not advance or retreat relative to the cylinders, the pair of press cylinders 56 extend in sync with each other, causing the push plate 53 to rotate around the pin 54 (rotating in the clockwise direction in FIG. 12), and when they contract in sync with each other, the push plate 53 rotates around the pin 54 (rotating in the counterclockwise direction in FIG. 12).

[0022] The loading device 5 also has an operation unit 57 as an action input unit for an operator who throws garbage into the garbage dump box 4 from the throw-in opening 41 to operate the loading device 5. This operation unit 57 is provided with an input unit for performing various inputs such as an ON / OFF button and switches for the loading device 5, an emergency stop button, a reset button, etc. for the loading device 5. This operation unit 57 also has various input units such as switches, buttons, dials, etc. for setting the control of the loading device 5 and changing these settings.

[0023] The operating unit 57 is located at the rear end of the garbage dump box 4, more specifically, on both sides of the dump opening 41 in the vehicle width direction, so that it can be operated by a worker or the like while dumping garbage into the dump opening 41.

[0024] Next, the discharge device 6 will be described. Fig. 1 shows the arrangement of the discharge device 6 in the dust collection box 3 (shown by a two-dot chain line). The discharge device 6 is a device for discharging dust in the dust collection box 3 to the outside through the opening 31 in an open state. The discharge device 6 of this embodiment includes a discharge plate 61, a discharge plate cylinder 62, and a bracket assembly 63.

[0025] The discharge plate 61 is also called a "discharge plate" and has a discharge plate body 611 and a support frame body 612. The discharge plate body 611 is a plate-shaped portion located so as to block the inside of the garbage storage box 3 in the vehicle width direction and the up-down direction in a vertical cross section in the vehicle width direction. The discharge plate body 611 has a generally "L"-shaped vertical cross section in the front-rear direction, with the upper half extending in the vertical direction and the lower half protruding rearward as it moves downward. The support frame body 612 is fixed to the front of the discharge plate 61 and reinforces the discharge plate body 611. In addition, the support frame body 612 moves forward and backward inside the garbage storage box 3 while being guided by a guide rail (not shown) provided on the inner surface of the garbage storage box 3 in the vehicle width direction. As a result, the discharge plate body 611 moves forward and backward while maintaining the generally "L"-shaped posture. The support frame body 612 receives the driving force of the discharge plate cylinder 62. The discharge plate 61 can move from the front (the position shown in Figures 1 and 12 (dotted line)) to the rear (the position shown in Figure 12 (solid line)) inside the dust storage box 3, allowing the rear surface of the discharge plate main body 611 to push dust toward the opening 31.

[0026] The discharge plate cylinder 62 is a hydraulic cylinder connected to the discharge plate 61 so that a driving force can be transmitted thereto. The hydraulic cylinder used for the discharge plate cylinder 62 may be a single-acting or double-acting type. The discharge plate cylinder 62 is provided in the center of the garbage storage box 3 in the vehicle width direction. The discharge plate cylinder 62 is hydraulically expanded and contracted in the front-rear direction in response to the control of the control unit, generating a driving force for moving the connected discharge plate 61 in the front-rear direction. As shown in FIG. 1, the discharge plate cylinder 62 has a cylinder portion 62A located at the rear and a piston rod portion 62B located at the front. The piston rod portion 62B is a so-called "telescopic type" that expands and contracts in multiple stages as shown in the expanded state in FIG. 12, and can move the discharge plate 61 in the front-rear direction from the front end inside the garbage storage box 3 to near the rear end as it expands and contracts. The discharge plate cylinder 62 is arranged in a "rearward-sloping" manner in the garbage storage box 3, with the rear end located lower than the front end.

[0027] In this embodiment, the connection of the discharge plate cylinder 62 to the discharge plate 61 is indirect via the bracket assembly 63 at the cylinder portion 62A. As shown in Fig. 2, the cylinder portion 62A is formed with a connecting portion 621, which is a rod-shaped portion for connecting to the discharge plate 61, so as to protrude on both sides in the vehicle width direction at the cylinder portion 62A. On the other hand, the piston rod portion 62B is directly connected. To connect the piston rod portion, as shown in Fig. 1, a part of the lower front end of the trash storage box 3 protrudes forward, and the front end of the discharge plate cylinder 62 (piston rod portion 62B) is pin-connected to the protruding portion and connected to be rotatable within a predetermined range.

[0028] 1, the bracket assembly 63 is interposed between the discharge plate 61 (specifically, the support frame 612 located on the front side) and the discharge plate cylinder 62. The bracket assembly 63 has a form shown in Figures 2(a) and (b) in a used state, and includes a cylinder support 631, a bracket base 632, and a fixing means 633.

[0029] The cylinder support 631 is flat as a single unit, and has the form shown in each of the figures of Fig. 4 (a) to (d) when viewed in the thickness direction. The cylinder support 631 has a support part for arranging the connecting part 621 of the discharge plate cylinder 62. The support part in this embodiment is a support hole 6311 which is a through hole formed in the thickness direction of the cylinder support 631 and has a space for passing the connecting part 621. In this embodiment, the connecting part 621 is a rod-shaped part, and the corresponding support part is the support hole 6311 which is a through hole, so that the configuration for connecting to the discharge plate 61 is simple. Note that the support part may have a form other than a hole as long as it can support the connecting part 621. For example, the support part can be configured to support the connecting part 621 by engagement. In this embodiment, the caps 622 are placed on both ends in the vehicle width direction of the connecting part 621 of the discharge plate cylinder 62, and in the use state, as shown in Fig. 2 (a), the caps 622 are inserted into the support holes 6311. The cap 622 is stationary, and the rotation of the connecting part 621 corresponding to the change in angle caused by the extension and contraction of the discharge plate cylinder 62 is received by the cap 622. As shown in each of Figures 4(a) to (d), a plurality of types of cylinder supports 631 are prepared, each having a different position of the support hole 6311 in the front-rear direction during use.

[0030] The cylinder support 631 of the present embodiment has a bulging portion 6312 that protrudes rearward from the other portion of the rear end surface. The rear end surface of the bulging portion 6312 is a curved surface (more specifically, an arc-shaped surface).

[0031] The bracket base 632, as shown in FIG. 2(a) for its bottom shape and in FIG. 2(b) and FIG. 3 (single unit view), includes a flat base plate 6321 and two protruding portions 6322 that protrude forward from the base plate 6321 and are positioned parallel to each other in the vehicle width direction. Each protruding portion 6322 is flat and has the same thickness as the cylinder support 631. The bracket base 632 is a separate body that is detachable from the cylinder support 631. The bracket base 632 is combined with the cylinder support 631 at the protruding portions 6322 and fixed to the discharge plate 61. Two cylinder supports 631 are combined with one bracket base 632.

[0032] The bracket base 632 has a fitting portion 6323 into which the bulging portion 6312 of the cylinder support 631 fits. The fitting state between the bulging portion 6312 and the fitting portion 6323 forms an arc shape that protrudes in the front-rear direction (more specifically, rearward). This allows the bracket assembly 63 to effectively resist vertical forces caused by vibrations while the vehicle is traveling.

[0033] The fixing means 633 is provided across the cylinder support 631 and the bracket base 632, so that the two can be fixed together. The fixing means 633 basically performs fixing without welding. In this embodiment, a bolt is used. As shown in FIG. 2(a), the bolt, which is the fixing means 633, is inserted from the front, penetrates the cylinder support 631, and is screwed into the bracket base 632 to be fixed. As a result, the rear end surface of the cylinder support 631 and the front end surface of the bracket base 632 are bolted in a state of abutment. The rear end surface of the cylinder support 631 and the front end surface of the bracket base 632 are formed in a shape with corresponding concaves and convexes. Therefore, the abutment state between the two is a state in which the surfaces are in close contact with each other. Therefore, the two are firmly fixed by the bolt. The bolt is attached at two places, top and bottom. Of the two bolts used, the one provided at the top is longer than the one provided at the bottom. For this reason, the cylinder support 631 and the bracket base 632 are each formed with two bolt insertion holes 6313, 6324 in the front-rear direction (direction perpendicular to the thickness direction) when in use.

[0034] In addition, as shown in FIG. 2(b), when the cylinder support 631 and the bracket base 632 are assembled, the upper boundary is located at the rear and the lower boundary is located at the front. Due to this positional relationship, compared to a configuration in which the front-rear positions of the upper boundary and the lower boundary are the same, the crossing angle between the direction of the driving force of the discharge plate cylinder 62 and the arrangement direction of the upper and lower boundaries of the bolt insertion holes 6313 and 6324 due to the discharge plate cylinder 62 being arranged "downward from the rear" in the garbage storage box 3 as described later can be made close to a right angle. Therefore, the oblique driving force of the discharge plate cylinder 62 is unlikely to act on the bolts at each boundary of the bolt insertion holes 6313 and 6324, so that the assembled state of the cylinder support 631 and the bracket base 632 can be stably maintained.

[0035] Furthermore, because the boundaries of the bolt insertion holes 6313, 6324 are offset forward and backward, even if the driving force of the discharge plate cylinder 62 causes the upper boundary to shift downward, the cylinder support 631 is supported from below by the forward protruding portion 6322 at the lower position, so that the upper boundary does not shift. Similarly, the lower boundary does not shift downward. Therefore, shear force is unlikely to be generated in the bolt at each boundary of the bolt insertion holes 6313, 6324, and the bolt is unlikely to break.

[0036] The bolt insertion hole 6313 in the cylinder support 631 is a through hole extending in the front-rear direction from the front end surface to the rear end surface of the cylinder support 631. The bolt insertion hole 6313 in the cylinder support 631 is a through hole with a smooth inner peripheral surface and no threads. The bolt insertion hole 6324 in the bracket base 632 is a through hole with one formed on the upper side extending in the front-rear direction from the front end surface of the protruding portion to the rear end surface, and a bottomed hole with one formed on the lower side extending rearward from the front end surface of the protruding portion. The bolt insertion hole 6324 in the bracket base 632 is a threaded hole with a thread formed on the inner peripheral surface, into which the shaft of a bolt is screwed.

[0037] A plurality of types of cylinder supports 631 are prepared, each having a different position of the support hole 6311 in the front-rear direction. The bracket assembly 63 is constructed by combining a type of cylinder support 631 selected according to the dimensional relationship of the discharge plate cylinder 62 to the trash collection box 3 in the front-rear direction with the bracket base 632. The bracket assembly 63 thus constructed can change the front-rear direction position of the support hole 6311 in stages depending on the selected cylinder support 631, as shown by the solid line and the two-dot chain line in FIG. 2(b). Therefore, the mounting dimension of the discharge plate cylinder 62 in the trash collection box 3 can be adjusted.

[0038] With this configuration, the only welding required is between the bracket base 632 and the discharge plate 61, eliminating the need to sandwich a spacer between them as in the past. Therefore, when attaching the discharge plate cylinder 62 to the garbage collection box 3, the number of welding points can be reduced.

[0039] The combination of the cylinder support 631 and the bracket base 632 is not limited to the form shown in Fig. 2(a)(b), Fig. 3, and Fig. 4(a)-(d) of this embodiment, and can be variously modified. Other form examples of the bracket base 632 are shown in Fig. 6 and Fig. 9. Other form examples of the cylinder support 631 are shown in Fig. 7(a)-(d) and Fig. 10(a)-(d). The support hole 6311 may have a form in which a part communicates with the outer radial part and has an open space, as shown in Fig. 7(a)-(d). In particular, the communicated part may be large and have a notch-like form, as shown in Fig. 7(a). Even with these shapes, by combining the cylinder support 631 and the bracket base 632 as shown in Fig. 10(a)-(d), the same function as the form shown in Fig. 2(b) can be exhibited. Further, other examples of the bracket assembly 63 formed by combining the bracket bases 632 and the cylinder supports 631 are shown in Figs. 8(a) to (d) and 11(a) to (d).

[0040] Here, the discharge plate cylinder 62 is arranged in a "rearward downward" position in the garbage storage box 3. Therefore, the extension and contraction of the discharge plate cylinder 62 is also performed along the "rearward downward" direction, so the driving force when moving the discharge plate 61 from the front to the rear also acts in the same direction. Therefore, this driving force is applied more to the rear lower part of the bracket assembly 63. In the bracket assembly 63 of the embodiment shown in FIG. 2(b) and the other embodiments shown in FIGS. 8(a) to (d), the rear lower parts of the rear end surface of the cylinder support 631 and the front end surface of the bracket base 632 are curved surfaces (more specifically, arc-shaped surfaces). Therefore, stress concentration due to the driving force of the discharge plate cylinder 62 is unlikely to occur, and the bracket assembly 63 is unlikely to be damaged even if it is repeatedly subjected to the driving force as the discharge plate cylinder 62 extends and contracts.

[0041] In addition, in the cylinder support 631 shown in Figs. 7(b) to (d), a claw-shaped portion 6314 is formed so as to wrap around from the rear of the support hole 6311 to the front downward. Therefore, in the bracket assembly 63 of Fig. 2(b) and Figs. 8(a) to (d) (excluding Fig. 8(a)), the driving force of the discharge plate cylinder 62 acting in the "rear downward" direction is received by the cylinder support 631 through the claw-shaped portion 6314 and then transmitted to the bracket base 632. Therefore, in these forms of bracket assembly 63, both the cylinder support 631 and the bracket base 632 function to transmit the driving force from the discharge plate cylinder 62 to the discharge plate 61. Therefore, the bracket assembly 63 is less likely to be damaged due to the driving force being concentrated on some members.

[0042] On the other hand, the rear end surface of the cylinder support 631 and the front end surface of the bracket base 632 may be a combination of multiple flat surfaces, as shown in Fig. 9 when the bracket base 632 has the form shown in Fig. 9, the cylinder support 631 has the form shown in Fig. 10(a) to (d), and the combined bracket assembly 63 has the form shown in Fig. 11(a) to (d). Even in this form, the rear lower surface 6315, which is a part of the rear end surface of the cylinder support 631, and the surface 6325 of the bracket base 632 that abuts therewith are inclined surfaces whose normal line is in the "rear downward" direction, so that the driving force of the discharge plate cylinder 62 acting in the "rear downward" direction can be effectively transmitted from the cylinder support 631 to the bracket base 632 by this inclined surface.

[0043] Although one embodiment of the refuse collection vehicle according to the present invention has been described above, the present invention can be modified in various ways without departing from the spirit and scope of the present invention. The specific configurations of the various parts are not limited to those of the above embodiment.

[0044] For example, the loading device 5 in the above embodiment was a "push plate type" having a push plate 53, but it may also be a "rotating plate type" having a rotating plate that is placed inside the garbage dump box 4 and moves the garbage by rotating.

[0045] In addition, in the above embodiment, the fixing means 633 is a bolt separate from the cylinder support 631 and the bracket base 632, but for example, it may be formed as at least a part of the cylinder support 631 and the bracket base 632, and the cylinder support 631 and the bracket base 632 may be fixed by, for example, recess-projection fitting. Even if the fixing means 633 is separate from the cylinder support 631 and the bracket base 632, fastening means of various structures can be used, not limited to bolts. In addition, the fixing means 633 is basically fixed without welding, but depending on the situation, it is not impossible to select welding as the fixing means 633. In addition, for example, bolt fastening and welding may be used in combination to fix the cylinder support 631 and the bracket base 632.

[0046] 2(b) of the above-described embodiments, the cylinder support 631 has the bulging portion 6312 which is a convex portion, and the bracket base 632 has the fitting portion 6323 which is a concave portion. However, the shape relationship may be reversed, so that the cylinder support 631 has the fitting portion which is a concave portion, and the bracket base 632 has the bulging portion which is a convex portion.
