Description

  The present invention relates to a container for transporting waste.

  2. Description of the Related Art Conventionally, there is known a waste transport container (hereinafter simply referred to as a container) that is detachably loaded on a vehicle such as a truck and into which waste is carried from a waste relay facility such as a compactor (trash compressor). For example, Patent Documents 1 and 2 describe this type of container.

  The containers described in Patent Documents 1 and 2 are transported to a waste carry-in site by a vehicle and then connected to a compactor. The container includes a push gate that is attached to a pushing ram of the compactor. The push gate is configured to be separable from the container body. After the push gate is mounted on the pushing ram, the push gate advances and retreats together with the pushing ram, and pushes the waste in the compactor into the container body. After filling the container main body with the waste, the push gate is mounted on the container main body, and serves as a lid so that the waste in the container main body does not spill outside.

  As described above, the container is loaded on a vehicle and transported to a waste delivery site. FIG. 13 is a diagram schematically illustrating a state in which the container 101 is loaded and transported on the vehicle 100. When the vehicle 100 travels, an airflow A is generated around the vehicle 100 from the front to the rear. The airflow A flows backward along the upper surface of the container 101, but has a property of wrapping forward in the rear of the container 101. Therefore, during traveling in snow, snow may be sprayed on the surface of the push gate 113 together with the airflow A, and snow may accumulate on the surface of the push gate 113. Further, there is a concern that mud rolled up from the road surface may accumulate on the surface of the push gate 113 during traveling in the rain or the like.

  The container 101 is connected to the compactor at the waste carrying-in site, and at that time, the push gate 113 is mounted on the pushing ram of the compactor. However, if snow or mud accumulates on the surface of the push gate 113, the snow or mud will be interposed between the push gate 113 and the pushing ram, so that the push gate 113 is mounted on the pushing ram well. There is a risk of being lost. Before connecting the container 101 to the compactor, scraping snow and mud from the surface of the push gate 113 in advance can prevent the push gate 113 from being mounted poorly. However, in that case, an extra work for scraping off snow and mud is required.

  The present invention has been made in view of such a point, and the object of the present invention is that a push gate and a part of a waste relay facility (such as a compactor pushing ram) can be used without scraping snow or mud. An object of the present invention is to provide a container for transporting waste that can prevent poor mounting.

The waste carrying container according to the present invention is a waste carrying container that is detachably loaded on a vehicle and into which waste is carried from a waste relay facility. The container for transporting waste is detachably attached to the container main body having a waste inlet formed at a rear portion thereof, and the container main body so as to block a part of the inlet. A push gate that is detached from the container body and attached to a part of the waste relay facility, and is detachably attached to the container body so as to close a part of the carry-in entrance, and is disposed above the push gate. And the subgate disposed at the rear of the container main body, and when the vehicle loaded with the waste transporting container is traveling, it moves downward from above along the surface of the push gate. And an air flow forming member that forms an air flow toward the. The airflow forming member includes a suction port formed in a front wall or an upper wall of the sub-gate, a discharge port formed in a rear wall of the sub-gate, and a suction port formed in the sub-gate, and the suction port and the discharge port. And an air flow path connecting the air flow path, a portion located outside the air flow path, and a portion located inside the air flow path, and a rectifying member having a space formed therein. A portion of the rectifying member that is located outside the air flow path is formed with a suction port that sucks air into the space, and a portion of the rectifying member that is located inside the air flow path is the space. A suction port for sucking air from the air flow path toward the air flow path is formed. An opening for sucking air outside the container body is formed in the sub-gate, and the suction port of the rectifying member communicates with the opening of the sub-gate.

  According to the waste transporting container according to the present invention, when the vehicle is traveling, the airflow forming member forms an airflow from the upper side to the lower side along the surface of the push gate. In other words, an air curtain is formed on the surface of the push gate by the airflow forming member. Therefore, even when an airflow that circulates forward in the rear of the container for transporting waste occurs as the vehicle travels, the airflow hits the surface of the push gate because of the airflow formed by the airflow forming member. It is suppressed. Therefore, accumulation of snow and mud on the surface of the push gate is suppressed. Therefore, even if snow and mud are not scraped off from the surface of the push gate, the push gate can be satisfactorily attached to a part of the garbage relay facility, and poor push gate attachment can be prevented.

In addition, according to the container for transporting waste according to the present invention, an airflow is generated from the front to the rear as the vehicle travels, and a part of the airflow flows into the air flow path from the suction port and from the discharge port. Discharged. Air discharged from the discharge port forms an air flow from the upper side to the lower side along the surface of the push gate. In this way, an air curtain can be formed on the surface of the push gate using the airflow generated as the vehicle travels. In addition, by forming the airflow forming member inside the subgate in this way, the entire airflow forming member and the subgate can be reduced in size. Moreover, since the airflow forming member is built in the sub-gate, it is possible to more reliably avoid interference between the airflow forming member and the lifting body of the waste relay facility.

Further, according to the waste transport container according to the present invention, the air introduced from the suction port of the air flow path can be smoothly guided to the discharge port, and can be discharged well from the discharge port. An air blower that conveys air is unnecessary and a drive source is not required, so energy saving can be achieved. In addition, the subgate can be reduced in size and weight as compared with the case where a blower is provided inside the subgate.

Further, according to the waste transport container according to the present invention, when air flows around the rectifying member, the pressure of the air outside the rectifying member is lower than the pressure of the air in the internal space. Internal air is sucked out through the suction port. As a result, the airflow is increased in the middle of the air flow path. Therefore, more air than the amount of air sucked from the suction port can be discharged from the discharge port, and a better air curtain can be formed on the surface of the push gate.

According to a preferred aspect of the present invention, the sub-gate is configured to be detached from the container main body and attached to the lifting / lowering body of the waste relay facility when the waste is carried in .

  The sub-gate is mounted on the lifting body of the garbage relay facility and moves up and down together with the lifting body. Thereby, the waste pushed out in a container main body by a part of garbage relay facility and a push gate can be sheared by a subgate with a raising / lowering body. Further, when waste is pushed into the container main body, it is possible to prevent a part of the waste from spilling out from the container main body. By providing the airflow forming member on the sub-gate, the airflow forming member is also lifted and lowered together with the lifting body. Therefore, the interference between the lifting body and the airflow forming member can be avoided, and the waste can be favorably sheared.

  According to another preferred embodiment of the present invention, the suction port comprises a forward opening formed in the upper part of the front wall of the sub-gate, and the discharge port is formed in the upper part of the rear wall of the sub-gate. It consists of a diagonally downward opening.

  By forming the rear obliquely downward discharge port at the upper part of the rear wall of the sub-gate, the air flow discharged from the discharge port flows not only on the surface of the push gate but also on the surface of the sub-gate. Therefore, accumulation of snow and mud on the surface of the subgate is also suppressed. Therefore, it is possible to prevent the mounting failure of the sub-gate with respect to the lifting body of the garbage relay facility.

  According to another preferable aspect of the present invention, the rectifying member is formed by a wing body whose upper wall is curved in a convex shape, and the suction port is formed in the upper wall of the wing body.

  As a result, the air in the air flow path can be suitably rectified, and the airflow can be increased sufficiently. Therefore, a better air curtain can be formed on the surface of the push gate.

  According to another preferred embodiment of the present invention, a plurality of the suction ports are formed in the left-right direction.

  This makes it easy to increase the airflow, and it is possible to increase the airflow evenly over the left and right direction of the rectifying member.

  As described above, according to the present invention, it is possible to provide a waste transport container that can prevent poor installation of a push gate to a part of a garbage relay facility without performing a scraping operation of snow or mud.

  Hereinafter, an embodiment of the present invention will be described with reference to the drawings. As shown in FIG. 1, a waste transport container 1 according to the present embodiment is detachably loaded on a vehicle 100 such as a truck, and waste is carried from a compactor described later. FIG. 1 schematically shows a state in which a vehicle 100 loaded with a container 1 is traveling.

  FIG. 2 is a side view of the container 1, and FIG. 3 is a rear view of the container 1. As shown in FIG. 3, the container 1 includes a container main body 2, a push gate 11, and a sub gate 12. In this specification, a portion of the container 1 other than the push gate 11 and the sub gate 12 is referred to as a container body 2.

  As shown in FIG. 2, the container main body 2 includes a box body 2A that stores waste, and a tailgate 3 provided at a rear portion of the box body 2A. The box 2A is formed in a substantially rectangular parallelepiped shape elongated in the front-rear direction. Wheels 4 are attached to the bottom of the box 2A. A carry-in port 5 into which waste is carried is formed at the rear part of the box 2A. The tailgate 3 is provided around the carry-in entrance 5.

  As shown in FIG. 3, a push gate 11 and a sub gate 12 are detachably attached to the tail gate 3. The sub gate 12 is disposed above the push gate 11. The push gate 11 and the sub gate 12 are formed so as to close the carry-in entrance 5. Specifically, the push gate 11 is formed to block the lower portion of the carry-in entrance 5, and the sub-gate 12 is formed to close the upper portion of the carry-in entrance 5.

  A lower lock member 13 and an upper lock member 14 are provided on the left and right sides of the rear portion of the box 2A. The lower lock member 13 is a member that locks the push gate 11 to the tail gate 3. The lower lock member 13 includes a pair of upper and lower horizontal bars 13a and a vertical bar 13b that connects the horizontal bars 13a. The lower lock member 13 is moved left and right by a drive mechanism (not shown). The specific configuration of the drive mechanism is not limited at all, and, for example, a hydraulic mechanism or an electric mechanism can be suitably used. Further, it is possible to omit the drive mechanism and to manually operate the lower lock member 13. When the lower lock member 13 moves to the vehicle center side, the horizontal bar 13 a is fitted into both the lateral hole 15 of the tailgate 3 and the lateral hole 16 of the push gate 11. Thereby, the push gate 11 is locked, and the push gate 11 cannot be detached from the tail gate 3. On the contrary, when the horizontal bar 13a moves to the outside in the vehicle width direction, the horizontal bar 13a is detached from the lateral hole 16 of the push gate 11. As a result, the lock of the push gate 11 is released, and the push gate 11 can be detached from the tail gate 3.

  The upper lock member 14 is a member that locks the sub-gate 12 to the tail gate 3. The upper lock member 14 includes a pair of upper and lower horizontal bars 14a and a vertical bar 14b that connects the horizontal bars 14a. Similar to the lower lock member 13, the upper lock member 14 is moved left and right by a drive mechanism (not shown). Also for this drive mechanism, various mechanisms such as a hydraulic mechanism or an electric mechanism can be used. Further, it is possible to omit the drive mechanism and to manually operate the upper lock member 14. When the upper lock member 14 moves to the vehicle center side, the horizontal bar 14 a is fitted into both the lateral hole 17 of the tailgate 3 and the lateral hole 18 of the sub-gate 12. As a result, the sub-gate 12 is locked, and the sub-gate 12 cannot be detached from the tail gate 3. On the contrary, when the horizontal bar 14a moves to the outside in the vehicle width direction, the horizontal bar 14a is detached from the lateral hole 18 of the sub-gate 12. Thereby, the lock of the sub-gate 12 is released, and the sub-gate 12 can be detached from the tail gate 3.

  As schematically shown in FIG. 4, the sub-gate 12 is provided with an air flow forming member 50 that forms an air flow A <b> 3 from the upper side to the lower side at least along the surface of the push gate 11. The configuration of the airflow forming member 50 will be described later. A part of the airflow A3 becomes an air curtain along the surface of the push gate 11. In the present embodiment, the discharge port 52 of the airflow forming member 50 is formed above the sub-gate 12. The airflow A3 discharged from the discharge port 52 flows along a part of the surface of the sub-gate 12 as well as the push gate 11. For this reason, the air flow A <b> 3 is directed downward from above along a part of the surface of the sub-gate 12, thereby forming an air curtain on the surface of the sub-gate 12.

  As shown in FIG. 3, openings 19 are formed on the left and right sides of the sub-gate 12. FIG. 5 is a front view of the left half of the sub-gate 12 (in other words, a view of the left half of the sub-gate 12 viewed from the rear of the vehicle 100). 6 is a sectional view taken along line VI-VI in FIG. As shown in FIG. 6, the airflow forming member 50 is provided on the upper portion of the sub-gate 12. The airflow forming member 50 can be provided outside the sub-gate 12, but in this embodiment, it is provided inside the sub-gate 12. The airflow forming member 50 is integrated with the sub-gate 12.

  The air flow forming member 50 is formed in the suction port 51 formed in the front wall 12f of the sub-gate 12, the discharge port 52 formed in the rear wall 12b of the sub-gate 12, and the sub-gate 12, and the suction port 51 and the discharge port. The air flow path 53 which connects 52 is provided. The suction port 51 is not limited to the front wall 12f, and may be formed in the upper wall 12t of the subgate 12. The suction port 51 may be formed over the front wall 12f and the upper wall 12t. The suction port 51 of the present embodiment is open forward and is formed so as to suck air from the front. In addition, the code | symbol 2t in FIG. 6 represents the upper surface (= upper surface of the container main body 2) of the box 2A. The suction port 51 is disposed above the upper surface 2t of the container main body 2, and sucks air flowing from the front to the rear along the upper surface 2t of the container main body 2. The discharge port 52 is opened rearward and obliquely downward. Air is discharged diagonally downward.

  As shown in FIG. 7, a rectifying member 60 is disposed in the air flow path 53. The rectifying member 60 plays a role of guiding the air sucked from the suction port 51 to the discharge port 52. In this embodiment, the rectifying member 60 is formed by a wing body in which the upper wall 61 is curved in a convex shape. The rectifying member 60 includes an upper wall 61 that is curved in a convex shape, and a lower wall 62 that is a flat plate. The upper wall 61 and the lower wall 62 may be separate or integrated. A space 65 is formed between the upper wall 61 and the lower wall 62. In other words, a space 65 is formed inside the rectifying member 60. The front end portion 61 a of the upper wall 61 protrudes forward from the front end portion 62 a of the lower wall 62. However, the shapes of the upper wall 61 and the lower wall 62 are not particularly limited, and the front end portion 61 a of the upper wall 61 may not protrude forward from the front end portion 62 a of the lower wall 62.

  The sub-gate 12 includes a guide plate 21 that extends rearward and obliquely upward, a guide plate 22 that extends horizontally from the rear end of the guide plate 21, and a guide plate 23 that extends obliquely downward and rearward from the rear end of the guide plate 22. . In the present embodiment, the guide plates 21, 22, and 23 are integrated, but some or all of them may be separate. The guide plate 21 is disposed behind the suction port 51. The guide plate 23 is disposed obliquely below the front of the rectifying member 60. The lower end 23 a of the guide plate 23 protrudes downward from the upper wall 24 of the sub-gate 12. The lower wall 62 of the rectifying member 60 is disposed in parallel with the guide plate 23. However, the arrangement of the lower wall 62 of the rectifying member 60 and the guide plate 23 is not particularly limited, and the lower wall 62 of the rectifying member 60 and the guide plate 23 do not necessarily have to be arranged in parallel.

  FIG. 8 is a front view of the rectifying member 60 (in other words, a view of the rectifying member 60 viewed from the rear of the vehicle). Reference symbol R1 represents a portion of the rectifying member 60 positioned inside the air flow channel 53, and reference symbol R2 represents a portion of the rectifying member 60 positioned outside the air flow channel 53. As shown in FIG. 8, a plurality of suction ports 63 are formed in the upper wall 61 of the rectifying member 60. The suction port 63 is formed in the portion R <b> 1 located inside the air flow path 53 of the rectifying member 60. Although the suction port 63 is exaggerated in FIG. 8, the actual suction port 63 is smaller than the suction port 63 illustrated in FIG. However, the size of the suction port 63 is not particularly limited. In the present embodiment, the suction port 63 is circular, but the shape of the suction port 63 is not particularly limited, and may be another shape such as a square. In the present embodiment, nine suction ports 63 are arranged at equal intervals in the left-right direction. However, the number of the suction ports 63 is not limited to nine. Further, the suction ports 63 are not necessarily arranged at equal intervals, and the interval between the adjacent suction ports 63 may not be constant. In the present embodiment, the shape and size of the plurality of suction ports 63 are the same, but the shape or size of some of the suction ports 63 may be different from other suction ports 63. In the present embodiment, all the suction ports 63 are disposed on the same straight line, but the suction ports 63 are not necessarily disposed on the same straight line. For example, the suction port 63 may be arranged in a zigzag manner.

  The left and right ends of the rectifying member 60 are open toward the side. Suction ports 64 for sucking air are formed on the left and right sides of the rectifying member 60. The suction port 64 is formed in a portion R <b> 2 located outside the air flow path 53 of the rectifying member 60. In the present embodiment, the suction port 64 is open to the side, but the suction port 64 may be formed in the upper wall 61 or the lower wall 62. As shown in FIG. 5, the suction port 64 of the rectifying member 60 communicates with the opening 19 of the sub-gate 12. Therefore, the air sucked from the opening 19 of the sub-gate 12 is guided to the space 65 (see FIG. 7) inside the rectifying member 60 through the suction port 64.

  As shown in FIG. 6, a convex portion 26 that protrudes rearward is formed below the airflow forming member 50 of the sub-gate 12. The air discharged from the discharge port 52 flows from the top to the bottom on the surface of the convex portion 26 and then flows from the top to the bottom on the surface of the push gate 11 (see FIG. 4).

  Next, the flow of air when the container 1 is loaded on the vehicle 100 and the vehicle 100 is traveling will be described. As shown in FIG. 1, when the vehicle 100 travels, an airflow from the front to the rear is generated around the vehicle 100. As shown in FIG. 7, a part of the airflow flowing along the upper surface of the container 1 (specifically, the upper surface 2t of the container body 2) (hereinafter referred to as the airflow A1) flows from the suction port 51 of the airflow forming member 50. It flows into the channel 53. The airflow A1 is divided into an airflow A11 that flows above the rectifying member 60 and an airflow A12 that flows below the rectifying member 60. Since the air flow A <b> 11 flows on the surface of the upper wall 61, the pressure of air on the surface of the upper wall 61 is lower than the pressure of air in the space 65 inside the rectifying member 60. Due to this pressure difference, air is sucked out from the space 65 to above the upper wall 61 through the suction port 63. The airflow A2 sucked out from the suction port 63 merges with the airflow A11, and further merges with the airflow A12 before being discharged from the discharge port 52. Therefore, the airflow A3 flowing out from the discharge port 52 has a larger amount of air than the airflow A1 flowing into the suction port 51. That is, the airflow forming member 50 increases the amount of air taken from the suction port 51 and discharges it from the discharge port 52. As the air in the space 65 is sucked out into the air flow path 53 through the suction port 63, the pressure in the space 65 decreases. As a result, air is sucked into the space 65 from the opening 19 of the sub-gate 12 through the suction port 64 of the rectifying member 60. The sucked air is supplied to the air flow path 53 through the suction port 63.

  As shown in FIG. 4, the air discharged from the discharge port 52 flows from the upper side to the lower side along the surface of the sub-gate 12 and the surface of the push gate 11. The airflow A3 from the discharge port 52 forms an air curtain on the surface of the sub-gate 12 and the surface of the push gate 11. Therefore, when the vehicle 100 is traveling in the snow, the airflow A3 suppresses the accumulation of snow on the surfaces of the push gate 11 and the sub gate 12. Moreover, accumulation of mud on the surfaces of the push gate 11 and the sub gate 12 is suppressed by the airflow A3.

  After the container 1 is transported to the waste carry-in site by the vehicle 100, it is connected to the compactor 70 (see FIG. 9) at the carry-in site. After the connection, waste is carried into the container 1 from the compactor 70. After the waste is carried in, the container 1 is removed from the compactor 70 and loaded on the vehicle 100. Then, the container 1 storing the waste is transported to the waste processing site by the vehicle 100. Next, the configuration of the compactor 70 will be described.

  FIG. 9 is a sectional view of the compactor 70. The compactor 70 includes a compactor main body 71 having a front end formed with an extrusion port 72. A hopper 74 that opens upward is attached to the front portion of the compactor body 71. A waste input port 73 is formed inside the hopper 74.

  In the compactor main body 71, a pushing ram 75 is housed slidably forward and backward (left and right in FIG. 9). A front portion 76 of the pushing ram 75 faces the extrusion port 72. The upper portion 77 of the pushing ram 75 extends horizontally. The upper surface of the pushing ram 75 is a shielding surface that can shield the charging port 73 of the hopper 74. A cylinder 78 is disposed between the pushing ram 75 and the rear wall of the compactor main body 71. When the cylinder 78 expands and contracts, the pushing ram 75 slides back and forth. As will be described later, the push gate 11 is attached to the front portion 76 of the pushing ram 5. When the pushing ram 75 moves forward (to the right in FIG. 9), the waste thrown in from the hopper 74 is pushed out from the extrusion port 72 by the push gate 11 and carried into the box 2A. When the pushing ram 75 moves forward, the upper portion 77 of the pushing ram 75 closes the charging port 73. This prevents waste from falling on the back surface of the pushing ram 75.

  Guide frames (not shown) are erected on both sides of the front portion of the compactor body 71. An elevating body 80 having substantially the same width as that of the pushing ram 75 is fitted in the guide frame so as to be movable up and down. The tip of the piston rod 79 </ b> A of the lifting cylinder 79 supported by the front wall of the hopper 74 is connected to the upper part of the lifting body 80. As the elevating cylinder 79 expands and contracts, the elevating body 80 moves up and down. An edge 81 that shears waste is formed at the lower end of the elevating body 80. A storage portion 83 that accommodates the sub-gate 12 is formed in the front portion of the elevating body 80. The storage portion 83 is provided with a plurality of engagement hooks 84 a that secure the sub-gate 12. The engagement hook 84a is formed so as to be swingable about the root portion. A similar engagement hook 84 is also provided at the front portion 76 of the pushing ram 75.

  The engaging hook 84 of the front portion 76 of the pushing ram 75 is formed to be able to engage with the push gate 11. When the engagement hook 84 engages with the push gate 11 and the lock of the lower lock member 13 of the container main body 2 is released, the push gate 11 is attached to the front portion 76 of the pushing ram 75. As a result, the push gate 11 can be detached from the container body 2, and moves forward and backward together with the pushing ram 75.

  The engaging hook 84a of the elevating body 80 is formed so as to be engageable with the sub-gate 12. When the engagement hook 84 a engages with the sub-gate 12 and the upper lock member 14 of the container body 2 is unlocked, the sub-gate 12 is attached to the lifting body 80. As a result, the sub-gate 12 can be detached from the container body 2, and moves up and down integrally with the lifting body 80.

  Next, the carrying-in of the waste with respect to the container 1 is demonstrated.

  First, the container 1 is lowered from the vehicle 100, and the container 1 is moved to a position where the rear portion of the container body 2 faces the extrusion port 72 of the compactor 70. That is, the container 1 is disposed at a position where the sub-gate 12 faces the lifting body 80 and the push gate 11 faces the front portion 76 of the pushing ram 75. Next, the container 1 and the compactor 70 are connected by a conventionally known lashing device (not shown).

  At this time, the push gate 11 is stored in the storage portion of the front portion 76 of the push-in ram 75, and the sub-gate 12 is stored in the storage portion 83 of the elevating body 80. The push gate 11 is attached to the pushing ram 75, and the sub-gate 12 is attached to the lifting body 80. As described above, according to the present embodiment, it is difficult for snow and mud to accumulate on the surfaces of the push gate 11 and the sub gate 12. For this reason, the push gate 11 is attached to the pushing ram 75 satisfactorily. Also, the sub-gate 12 is mounted on the lifting body 80 well.

  Next, the engagement hook 84 a is engaged with the sub-gate 12, the engagement hook 84 is engaged with the push gate 11, and the upper lock member 14 and the lower lock member 13 are unlocked.

  Next, the elevating cylinder 79 is contracted, and the elevating body 10 and the sub gate 12 are moved upward. Then, the extension and contraction of the cylinder 78 are repeated, and the pushing ram 75 is advanced and retracted. When the pushing ram 75 moves forward, the push gate 11 attached to the pushing ram 75 fills the box 2A of the container body 2 with the waste stored in the hopper 74 (see FIG. 10).

  When the box 2A of the container body 2 is filled with waste, the pushing ram 75 is retracted to a position substantially coincident with the rear surface of the elevating body 80, and then the elevating cylinder 79 is extended to lower the elevating body 80. . Then, the waste is sheared by the edge 81 of the elevating body 80, the pushing ram 75 and the push gate 11 (see FIG. 11).

  Next, the elevating cylinder 79 is contracted, and the elevating body 80 is raised until the lower surface of the elevating body 80 is located slightly above the upper surface of the pushing ram 75. At this time, the upper portion of the carry-in entrance 5 of the tailgate 3 remains covered by the sub-gate 12, so that waste is prevented from spilling out. Thereafter, the pushing ram 75 is repeatedly moved forward and backward (see FIG. 12). Thereby, the waste remaining behind the box 2A of the container body 2 is pushed into the box 2A while being compressed.

  Thereafter, the pushing ram 75 returns to the initial position, the sub-gate 12 is locked to the tail gate 3 by the upper lock member 14, and the push gate 11 is locked to the tail gate 3 by the lower lock member 13. Further, the engagement of the engagement hooks 84a and 84 is released. Then, after removing the container 1 from the compactor 70, the container 1 is loaded on the vehicle 100. Thereafter, the vehicle 100 loaded with the container 1 moves toward the waste disposal site.

  As described above, according to the present embodiment, when the vehicle 100 is traveling with the container 1 being loaded, even if an air flow that circulates forward is generated behind the container 1, The contact with the surface of the push gate 11 is suppressed by the air flow A <b> 3 formed by the air flow forming member 50. Therefore, snow accumulation on the surface of the push gate 11 is suppressed when the vehicle 100 travels in the snow. Further, mud is prevented from accumulating on the surface of the push gate 11. Therefore, the push gate 11 can be satisfactorily attached to the pushing ram 75 of the compactor 70 without scraping snow or mud from the surface of the push gate 11, and poor installation of the push gate 11 can be prevented.

  According to the present embodiment, the sub-gate 12 is provided above the push gate 11, and the sub-gate 12 is detachably mounted on the lift body 80 and is configured to move up and down together with the lift body 80. Therefore, the waste pushed into the container main body 2 by the pushing ram 75 and the push gate 11 can be sheared by the elevating body 80 and the sub gate 12. Further, it is possible to prevent a part of the waste from spilling out from the container main body 2 when the waste is pushed into the container main body 2. According to the present embodiment, the airflow forming member 50 is provided on the sub-gate 12. Therefore, the airflow forming member 50 moves up and down together with the lifting body 80. When the airflow forming member 50 is provided in a portion other than the sub-gate 12, there is concern about interference between the elevating body 80 that moves up and down and the airflow forming member that is stationary, and a device for preventing the interference is required. However, when the airflow forming member 50 is provided on the sub-gate 12 as in the present embodiment, the airflow forming member 50 moves up and down together with the lifting body 80, so that the airflow forming member 50 and the airflow forming member 50 can be moved up and down without any special measures. Interference with the body 80 can be avoided. Therefore, the waste shearing operation can be performed satisfactorily.

  In particular, according to the present embodiment, the airflow forming member 50 is formed inside the sub-gate 12. Therefore, compared with the case where the airflow forming member 50 is provided outside the subgate 12, the entire airflow forming member 50 and the subgate 12 can be reduced in size. Further, interference between the airflow forming member 50 and the elevating body 80 can be avoided more reliably.

  The airflow forming member 50 has a rear obliquely downward discharge port 52 formed in the upper part of the rear wall 12b of the sub-gate 12. Therefore, the air discharged from the discharge port 52 can flow from the upper side to the lower side along the surface of the sub-gate 12. Therefore, it is possible to suppress the accumulation of snow and mud on the surface of the sub-gate 12, and to prevent the mounting failure of the sub-gate 12 with respect to the lifting body 80.

  A rectifying member 60 is disposed in the air flow path 53 of the airflow forming member 50. The rectifying member 60 can smoothly guide the air from the suction port 51 toward the discharge port 52, and can discharge the air from the discharge port 52 satisfactorily. The rectifying member 60 is formed to discharge the airflow A3 from the discharge port 52 by using the airflow A1 generated as the vehicle 100 travels. The rectifying member 60 is a stationary member fixed to the air flow path 53, and unlike a blower or the like, a driving source such as a motor is not necessary. Since a drive source is unnecessary, energy saving can be achieved. Further, the sub-gate 12 can be reduced in size and weight compared to the case where a blower or the like is provided inside the sub-gate 12.

  A space 65 is formed inside the rectifying member 60, a suction port 64 is formed on the side of the rectifying member 60, and a suction port 63 is formed on the upper wall 61 of the rectifying member 60. With the flow of air (airflow A11) flowing on the surface of the upper wall 61, the air in the space 65 can be sucked out from the suction port 63, and the amount of air can be increased. According to the present embodiment, more air than the amount of air sucked from the suction port 51 can be discharged from the discharge port 52. Therefore, a better air curtain can be formed on the surfaces of the push gate 11 and the sub gate 12. In the present embodiment, the suction port 63 is formed on the upper wall 61 of the rectifying member 60, but the suction port 63 may be formed on the lower wall 62. It is also possible to form the suction port 63 on both the upper wall 61 and the lower wall 62.

  In the present embodiment, the rectifying member 60 is formed by a wing body having an upper wall 61 that is curved in a convex shape, and the suction port 63 is formed in the upper wall 61 of the wing body. Thereby, the air in the air flow path 53 can be suitably rectified, and the airflow can be increased sufficiently. As a result, a better air curtain can be formed on the surfaces of the push gate 11 and the sub gate 12.

  Further, according to the present embodiment, the plurality of suction ports 63 are formed in the left-right direction. Thereby, it is easy to increase the airflow in the air flow path 53, and it is possible to increase the airflow evenly in the left-right direction. As a result, a better air curtain can be formed on the surfaces of the push gate 11 and the sub gate 12.

  In the embodiment, the waste relay facility is configured by the compactor 70. The container 1 is connected to the compactor 70 so that the waste is carried from the compactor 70. However, the waste relay facility for carrying waste into the waste transport container according to the present invention is not limited to the compactor 70. The waste relay facility is a facility that can temporarily store waste (= garbage) and can carry waste into a waste transport container, but a facility other than the compactor 70 is used as a waste relay facility. It is also possible. For example, a dust screw or a dust drum may be used as the waste relay facility. In that case, the push gate of the waste transport container is detachably attached to a part of a dust screw, a dust drum, or the like. Further, the sub-gate of the container for transporting waste can be detachably attached to a lifting body such as a dust screw or a dust drum.
