Description

  The present invention relates to a garbage collection vehicle capable of loading garbage.

As a conventionally known garbage collection vehicle, a dust container, a dust container box connected to the rear side of the dust container box, and a dust container placed in the dust container box are disposed in the dust container box. Some have a loading device that performs a loading operation. The dust input box has an opening that opens to the dust storage box side, and the loading device performs an operation of loading the dust input to the dust storage box into the dust storage box through the opening. .
Further, the dust box can be rotated upward with its upper part as a center, thereby enabling opening / closing operation with respect to the dust container. Then, in the open state in which the dust input box is rotated upward, the dust stored in the dust storage box is pushed rearward of the vehicle by the discharge plate provided in the dust storage box and discharged to the outside.
In order to prevent sewage generated from the dust storage box and dust in the dust input box from leaking outside between the dust storage box and the dust input box in the closed state where the dust input box is at the bottom, A seal member is provided therebetween. For example, in the garbage truck described in Patent Document 1, a seal member is provided on the front end surface of the dust container. And it has the sealing surface which the said sealing member contacts in the rear-end surface of a dust storage box.

Japanese Utility Model Publication 1-1607 (Fig. 4)

In the garbage truck described in Patent Document 1, when a foreign object is caught between the seal member and the seal surface, the seal member and the seal surface cannot be brought into close contact with each other at that portion, so that there is a gap. Arise. For example, if sewage leaks from the gap created between the side seal and its sealing surface, the left and right centrifugal force acting when the garbage truck turns left and right causes the leaked sewage to flow on the rear end surface of the dust storage box. There is a risk that the vehicle will travel outward in the vehicle width direction after passing through the side, and may be scattered outside the vehicle body.
Therefore, in view of such a conventional problem, the present invention provides a garbage collection vehicle that can prevent sewage leaking from between a dust storage box and a dust input box from going outside in the vehicle width direction of the vehicle body. The purpose is to provide.

The refuse collection vehicle of the present invention has a dust storage box, a dust input box connected to the rear side of the dust storage box, and an operation of loading the dust input into the dust storage box into the dust storage box. And a sealing member at least at the lower and side portions between the opposing surfaces of the dust container box and the dust container box that are opposed to each other in a state of being inclined downward toward the rear of the vehicle. In the garbage collection vehicle provided, the vehicle projects in the vehicle width direction outside of the side seal member from the dust storage box toward the dust input box, and from between the side seal member and its seal surface. The water stop member which suppresses that the sewage leaked to the outer side further goes out to the vehicle width direction outer side is provided, and the sewage receiving member which receives the leaked sewage is provided below the water stop member.
According to this configuration, even if sewage leaks from between the side seal member and the seal surface, the leaked sewage is removed from the refuse storage box on the outer side in the vehicle width direction than the side seal member. It can be received by the water-stopping member protruding toward the dust input box and can be prevented from coming out of the vehicle body. Furthermore, since each facing surface of the dust storage box on the front side and the dust box on the rear side is a surface inclined downward to the rear of the vehicle, the sewage leaked from between the side seal member and the seal surface is Although it flows along the rear end surface of the dust storage box side, the water stop member protrudes from the dust storage box side toward the dust input box side. Can be prevented from going outside. Furthermore, even if the leaked sewage flows downward between the sealing member and the water stop member, the sewage can be received by the sewage receiving member.

Moreover, in the said garbage collection vehicle, a part of member which comprises the outer wall of the said dust storage box is made into the said water stop member.
Thereby, the operation | work which attaches a water stop member to a separate dust storage box becomes unnecessary.
Moreover, the said water stop member can be set as the structure which has the overlapping part which overlaps with the front-end | tip part side in the vehicle front-back direction with respect to the side wall member of the front-end part of the said dust input box.
According to this, when viewed from the outside of the vehicle body, the side seal member is hidden. Therefore, even if the leaked sewage jumps directly to the side without connecting the water stop member from the side seal member, it is possible to prevent the sewage from jumping to the outside of the vehicle body because of the overlapping portion.

  According to the refuse collection vehicle of the present invention, even when sewage leaks to the outside from between the side seal member and the seal surface, the leaked sewage is prevented from flowing outside the vehicle body. It can be prevented by the water member. Furthermore, even if the leaked sewage flows downward between the seal member and the water stop member, the sewage is received by the sewage receiving member, and the sewage can be prevented from falling on the road.

FIG. 1 is a side view showing an embodiment of a garbage truck according to the present invention. This garbage collection vehicle is a press type that has a compression stroke in the dust loading operation, and is configured to push out the dust.
In FIG. 1, the garbage collection vehicle 1 includes a dust storage box 2 whose rear end is open, and a dust input box 3 connected to the rear side thereof. At the rear part of the dust input box 3, there is provided an input port 3a through which dust is input, and a lid 3b that is opened and closed by sliding up and down is provided corresponding to the input port 3a. In addition, an opening 3 d that is open to the dust container 2 side for loading dust into the dust container box 2 is formed in the lower front part of the dust container box 3.
The dust input box 3 can be rotated around a fulcrum P provided at the upper portion thereof, thereby enabling an opening / closing operation with respect to the dust storage box 2. The dust container 3 closes the dust container 2 at the position indicated by the solid line in the figure, opens the rear end of the dust container box 2 at the position rotated upward indicated by the two-dot chain line in the figure, and moves the dust behind Can be discharged.

A loading device 50 is provided in the garbage throwing box 3. The loading device 50 includes a slider 5 and a pushing plate 8 that is rotatably attached to a lower end portion of the slider 5 via a pin 7. The slider 5 can move along the guide rails 4 provided on the left and right side walls 3 c of the dust box 3. Push cylinders 9 are attached between the side surface member 5 a of the slider 5 and the side wall 3 c of the dust input box 3 on both the left and right sides in the dust input box 3. A press cylinder 12 is attached between the side member 8 a of the pushing plate 8 and the side member 5 a of the slider 5.
Therefore, from the state of FIG. 1, the pressing plate 8 is rotated counterclockwise by the contraction operation of the press cylinder 12 to reverse the pressing plate 8. Next, the slider 5 and the pushing plate 8 are both lowered obliquely backward by the contraction operation of the push cylinder 9, and the dust thrown in from the charging port 3a is compressed (primary compression). The pushing plate 8 is rotated clockwise by the extension operation of the press cylinder 12 to perform secondary compression. Then, the slider 5 and the pushing plate 8 are lifted obliquely forward by the extension operation of the push cylinder 9, and the compressed dust is pushed into the dust container 2 side (shown by the solid line from the state shown by the two-dot chain line in FIG. 1). Step to move to the state). As described above, the loading device 50 sequentially performs the reversing process, the primary compression process, the secondary compression process, and the pushing process as one cycle, and the dust put into the dust throwing box 3 is put into the dust containing box 2 through the opening 3d. Loading operation can be performed.

  A discharge plate 38 that is movable in the front-rear direction of the vehicle is provided inside the garbage storage box 2. One end portion 40 a of the telescopic discharge cylinder 40 is connected to the discharge plate 38, and the other end portion 40 b is connected to the end portion of the refuse storage box 2 in the vehicle front direction. The discharge plate 38 can be moved in a range from the position indicated by the solid line to the position indicated by the two-dot chain line by the expansion and contraction of the discharge cylinder 40. When the dust is empty, the discharge plate 38 is in a position indicated by a solid line, and a space S for loading dust in the rear direction of the vehicle from the discharge plate 38 is secured. The discharge plate 38 can compress the dust loaded by the loading device 50 between the push plate 8. The discharge device 51 having the discharge plate 38 expands the space S by intermittently moving the discharge plate 38 in the front direction of the vehicle to gradually increase the amount of dust stored in the dust storage box 2, and By moving the discharge plate 38 in the vehicle rearward direction, the dust stored in the dust storage box 2 can be discharged rearward.

FIG. 2 is a side view showing a lower portion between the dust storage box 2 on the front side and the dust input box 3 on the rear side. FIG. 3 is a cross-sectional view of FIG.
A seal member 15 is provided between the opposing surfaces 14a and 14b between the dust container 2 and the dust input box 3. More specifically, the facing surface 14a on the dust container box 2 side is the peripheral edge of the rear end surface of the dust container box 2, and the facing surface 14b on the dust container box 3 side is the peripheral edge of the front edge surface of the dust container box 3. A seal member (seal rubber) 15 is provided between the peripheral edge of the rear end surface of the dust container 2 and the peripheral edge of the front end surface of the dust container 3. The rear end surface of the dust container 2 is a surface facing obliquely upward, and the front end surface of the dust container box 3 in a closed state is a surface facing obliquely downward. It is set as the inclined surface shape which inclines downward toward back.

  The seal member 15 is formed by bending a long member into a “U” shape to form a lower seal 21 and left and right side seals 22. The lower seal 21 is provided below the opening 3d formed in the dust box 3, and the side seals 22 are provided on both the left and right sides of the opening 3d. The side seal 22 extends to above the opening 3d. Although not shown, the lower seal 21 extends in the vehicle width direction (left-right direction), and the lower end portions of the side seals 22 are continuous with the left and right end portions of the lower seal 21. In a state where the dust container 3 closes the dust container 2 (the state shown in FIG. 2), the side seals 22 extend upward (slanting upward upward) from the left and right ends of the lower seal 21.

A seal member 15 (side seal 22) is attached to the facing surface 14b on the front end face of the dust box 3. And the sealing surface 32 which this sealing member 15 contacts is formed in the opposing surface 14a in the rear-end surface of the dust storage box 2. As shown in FIG.
The side seal 22 is fixed by a mounting bracket 26 fixed to the facing surface 14b of the dust box 3. And the side part seal | sticker 22 is being fixed so that it may protrude from the opposing surface 14b to the vehicle front side.

In FIG. 3, a bottom wall 18 is provided on the outer side in the vehicle width direction of the seal surface 32 of the dust container 2 so as to be lower in front of the vehicle and obliquely downward than the seal surface 32. The bottom wall 18 is provided in parallel with the sealing surface 32 (a planar member forming the sealing surface 32). An inner wall 19 is interposed between the seal surface 32 and the bottom wall 18.
Further, a water stop member (protruding member) 16 is formed outside the side seal 22 in the vehicle width direction. The water stop member 16 is provided at the side edge of the rear end surface of the dust container 2 and protrudes from the bottom wall 18 to the dust container 3 side. The water stop member 16 has a plate shape and extends in the height direction along the side edge of the rear end surface of the dust container 2. The water stop member 16 is provided at least in a range in the height direction from the lower end to the upper end of the side seal 22, and is parallel to the side seal 22.

  In FIG. 2 and FIG. 3, a portion of the vehicle rear end portion which is a part of the plate member 30 constituting the outer wall of the dust container 2 is the water stop member 16. That is, the water stop member 16 is a portion in which the plate member 30 constituting the outer wall of the dust container 2 is extended rearward, and the water stop member 16 is formed integrally with the plate member 30. Thereby, the operation | work which attaches the water stop member 16 to the dust storage box 2 separately becomes unnecessary, and simplification of a structure and attachment operation | work can be achieved.

  As shown in FIG. 3, a concave groove 20 is formed by the inner wall 19, the bottom wall 18, and the water blocking member 16 on the outer side in the vehicle width direction of the side seal 22 (seal surface 32). Yes. The concave groove 20 serves as a passage for sewage leaking outward from between the side seal 22 and the seal surface 32, and serves as a guide groove for guiding the sewage to the sewage receiving member 17 provided below. A sewage receiving member 17 is provided below the concave groove 20, and the sewage flowing down the concave groove 20 is received at the end of the sewage receiving member 17.

  In FIG. 3, a plate member 27 protruding toward the dust container 2 side is provided at the side edge of the front end surface of the dust container 3. The plate member 27 is formed outside the side seal 22 in the vehicle width direction, and the front end (front end surface) of the plate member 27 is provided with a gap from the front end (rear end surface) of the water stop member 16. Further, a portion of the vehicle front end portion that is a part of the side wall member 28 that constitutes the outer wall of the dust box 3 is the plate member 27. The plate member 27 extends in the height direction along the side edge portion of the front end surface of the dust box 3, and the plate member 27 is at least in the range in the height direction from the lower end to the upper end of the side seal 22. Provided and parallel to the side seals 22. In FIG. 2, the lower ends of the side wall member 28 and the plate member 27 on the dust input box 2 side are positioned lower than the lower end of the side seal 22.

As shown in FIG. 2, a sewage receiving member 17 is provided below the water stop member 16. The sewage receiving member 17 can receive sewage leaked from between the sealing member 15 and the sealing surface. The sewage leaks from between the seal member 15 and the seal surface when, for example, a foreign object is caught between them.
The sewage receiving member 17 is a gutter member that opens toward the facing surfaces 14a and 14b (upward). As shown by the broken line in FIG. 3, the sewage receiving member 17 is provided over the entire length in the vehicle width direction. More specifically, the end portion of the sewage receiving member 17 extends beyond the side seal 22 to the outside in the vehicle width direction on both the left and right sides, and further than the outer side surface of the water stop member 16 in the vehicle width direction. It extends to the outside position.

Therefore, even if sewage leaks outward from between the side seal 22 and its sealing surface 32, the leaked sewage is caused, for example, by the left and right centrifugal force acting when the dust collecting vehicle 1 turns left and right. 19 and the bottom wall 18, even if it flows further outward in the vehicle width direction, the sewage is blocked by the water stop member 16 projecting from the dust storage box 2 to the dust input box 3 side and goes out of the vehicle body. It is suppressed. That is, since the facing surfaces 14a and 14b between the dust container box 2 on the front side and the dust container box 3 on the rear side are surfaces inclined downward, the leaked sewage flows along the bottom wall 18. However, since the water stop member 16 is continuously provided on the outer side in the vehicle width direction of the bottom wall 18 and protrudes toward the dust throwing box 3 side, the sewage is scattered outside. Can be prevented.
Further, since both the bottom wall 18 and the sealing surface 32 are inclined downward toward the rear, the sewage on the bottom wall 18 and the sealing surface 32 flows down along the respective surfaces. It is received by the sewage receiving member 17. Thereby, it can prevent that sewage falls on a road.

FIG. 4 is a perspective view showing the sewage receiving member 17 and the sewage tank 24 connected thereto. The sewage receiving member 17 will be further described. The sewage receiving member 17 is attached to the lower part of the dust box 3 and is provided below the lower seal (not shown) and the lower end (not shown) of the side seal. It has been. The left and right ends of the sewage receiving member 17 are provided below the lower end of the water stop member 16. The sewage receiving member 17 is a gutter member having an open top, so that sewage leaked from the facing surfaces 14a, 14b between the dust container 2 and the dust container 2 can flow. .
A sewage tank 24 is provided further below the refuse input box 3. The sewage tank 24 is provided over substantially the entire length of the garbage throwing box 3 in the vehicle width direction.

  The sewage receiving member 17 and the sewage tank 24 are communicated with each other by a water guide pipe 25 in the middle in the vehicle width direction. The sewage leaked from the opposing surfaces 14a, 14b between the dust container 2 and the dust input box 3 flows into the sewage receiving member 17, and the sewage flowing into the sewage receiving member 17 passes through the water guide pipe 25 and passes through the sewage. Guided to the tank 24. The water guide pipe 25 has an upper and lower pipe portion 25a extending in the vertical direction and a left and right pipe portion b extending perpendicularly to the left and right direction. Since the water guide pipe 25 is bent in this manner, the sewage tank is caused by the left / right centrifugal force acting on the vehicle body when the garbage collection vehicle 1 turns left and right, and the longitudinal inertial force acting on the vehicle body when suddenly starting and stopping. It is possible to make it difficult for the sewage stored in 24 to flow back to the sewage receiving member 17 through the water guide pipe 25.

FIG. 5 shows another embodiment of the garbage truck according to the present invention, and is a sectional view showing the side seal 22 and its peripheral portion. This embodiment is different from the embodiment shown in FIG. 3 with respect to the water stop member 16 on the dust container 2 side and the side wall member 28 on the dust input box 3 side. A part of the front end side (vehicle rear side) overlaps a part of the front end side (vehicle front side) of the side wall member 28 in the vehicle front-rear direction. That is, the water stop member 16 has an overlapping portion 37 that overlaps with the side wall member 28 on the dust throwing box 3 side in the front-rear direction of the vehicle on the tip end side. In other words, the overlapping portion 37 of the water blocking member 16 is a portion protruding rearward from the side edge portion of the front end of the dust throwing box 3. Also in this embodiment, a part of the side wall member 28 constituting the outer wall of the dust box 3 is the plate member 27, and the overlapping portion 37 of the water stop member 16 is attached to the plate member 27. On the other hand, they overlap in the vehicle longitudinal direction.
According to the overlapping portion 37, when the side portion of the vehicle body is viewed from the outside with respect to this portion, the side seal 22 is hidden. Therefore, sewage leaked from between the side seal 22 and its sealing surface 32 directly from the side seal 22 without passing through the bottom wall 18 due to the left and right centrifugal force acting on the vehicle body when the garbage truck 1 turns left and right. Even if it jumps out to the side in the vehicle width direction, since there is this overlapping portion 37, it becomes possible to prevent sewage from splashing outside the vehicle body.

Furthermore, although the dust collecting vehicle loading device 50 of the present invention has been described as a press type (FIG. 1), the dust collecting vehicle of the present invention has a rotating plate type loading device having a rotating plate and a pushing plate, although not shown. It may be provided.
Further, in each of the embodiments described above, the water stop member 16 is integrated with the plate member 30 constituting the outer wall of the dust container box 2, but as another embodiment, The part is a separate member from the plate member 30 constituting the outer wall of the dust container 2 (not shown). In this case, the water stop member 16 may be provided on the inner side in the vehicle width direction than the plate member 30 or may be provided on the outer side in the vehicle width direction of the plate member 30.

Moreover, the sealing member 15 should just be provided in the at least lower part and side part between opposing surface 14a, 14b, and, as other embodiment, the sealing member 15 is the said opening part currently formed in the dust bin 3 It may be provided over the entire circumference surrounding 3d. That is, an upper seal (not shown) that is continuous with the upper end of the side seal 22 may be provided above the opening 3d. In this case, the seal member 15 is formed in an annular shape by the lower seal 21, the side seal 22, and the upper seal. Thereby, even if the internal sewage rises through the side seal 22 due to the capillary phenomenon, the sewage can be prevented from leaking to the outside.
Moreover, although the said sealing member 15 was demonstrated as what was attached to the dust input box 3 side, as another embodiment, although not shown in figure, the sealing member 15 shall be attached to the dust storage box 2 side. .

It is a side view which shows one Embodiment of the refuse collection vehicle of this invention. It is a partially broken side view which shows the lower part between a dust storage box and a dust input box. It is sectional drawing of a side part seal | sticker and its peripheral part. It is a perspective view which shows a sewage receiving member and the sewage tank connected with this. FIG. 5 is a sectional view showing another embodiment of the garbage truck according to the present invention and showing a side seal and its peripheral part.
