Work hard. Both ends of the chain 31 are fixed to the fixed plate 25, and the gate 23 is raised and lowered by driving the prime mover 26, and the discharge port 17 is opened and closed. Further, a push link 32 is rotatably suspended from the fixed plate 25 by a pin 32, and the push link 32 is accommodated in the guide rail 22, and a pressing surface 32a is formed on the lower surface. A chute 34 is swingably supported at the lower part of the outlet tube 16 by a pin 35. It is located in front of the pivot point.

Both side plates 37 are extended rearward, and an operating rod 38 is provided at the rear end.
The lower end of the operating rod 38 is rotatably supported, and the upper end of the operating rod 38 is provided with a roller 39, which is inserted into the guide rail 22.
A transmission mechanism 40 is configured to face the pressing surface 32a of the push link 32. Reference numeral 41 denotes side covers provided on both sides of the outlet tube 16, which protrude forward.

On the other hand, links 42 are rotatably suspended by pins 43 at their upper ends at the lower ends of both sides of the gate 23.
A scraper 44 is rotatably suspended by a pin 45 at its base end between the lower ends of the scraper 44 .

The scraper 44 includes a bottom plate 46, an upper long plate 47, and an upper short plate 4.
8, it is formed into a generally Ξ-angular shape in side view, and the intersection of the bottom plate 46 and the upper short plate 48 is at an acute angle. Further, a bracket 49 is provided on the link 42 to project forward, and a damper 50 is provided between the bracket 49 and the upper long plate 47. The damper 50 provides resistance to the rotation of the scraper 44, and both ends of the fluid pressure cylinder 51 are connected to the bracket 49.
and the upper long plate 47 via a pin 52, and both boats 53 of the fluid pressure cylinder 51 are connected via a speed controller 54 (throttle valve) and a vibrator 55. Furthermore, a tension spring 56 is tensioned between the bracket 49 and the lower part of the gate 23, and the link 4
2 is biased rearward by a tension spring 56. Reference numeral 57 denotes a garbage collection vehicle, in which a garbage storage box 59 is mounted on a chassis 58, and the storage box 59 consists of a storage section 60 and a loading section 61 having a pushing device. The mouth 62 is open.

Next, the operation will be explained. When the discharge port 17 is closed with the gate 23 lowered (see FIG. 2), the pushing surface 32a of the push link 32 and the roller 39 come into contact and press the operating rod 38 downward. The chute 34 is held in a substantially horizontal retracted position, while the scraper 44 is bent forward in a substantially L-shape relative to the link 42 to remove the chute 3.
4 and the hydraulic cylinder 51 is in a contracted state. In this state, the garbage collection vehicle 57 is moved backward, the input port 62 is positioned near the tip of the chute 34, the prime mover 26 is driven to raise the gate 23, and the discharge port 17 is moved back.
to open.

Along with this rising operation, the scraper 44 also rises, but the working medium of the fluid pressure cylinder 51 is transferred to the speed controller 5.
4 partially restricts its movement, the downward rotation of the scraper 44 due to its own weight is slowed down by resistance, and is delayed compared to the rising speed of the gate 23. The scraper 44 has a spring 5
Although it rotates slightly backward together with the link 42 due to the spring force 6, it rotates slightly backwards with respect to the link 42. It rises in a substantially bent state (see FIG. 3), leaves the chute 34 without sliding, and does not move the garbage on the chute 34 backward. Thereafter, the scraper 44 is gradually rotated downward until it is approximately vertical, and the link 42 is rotated downward to the gate 23. (see Figure 4). On the other hand, the push link 32 also rises together with the gate 23, and the pushing surface 32a
is separated from the roller 39, the chute 34 tilts forward and downward due to its own weight and extends, and its tip engages the lower edge of the input port 62. Subsequently, the transport screw 8 is driven to discharge the garbage from the discharge port 17, move it on the chute 34, and load it into the storage box 59 from the input port 62. In addition, when closing the discharge port 17, when the gate 23 is lowered in the state shown in FIG. 17 Remove dust around the edges.

At this time, the link 42 and the scraper 44 are given resistance to rotation with respect to the gate 23 and the link 42 by the spring 56 and the speed controller 54, and the scraper 44 is applied to the outlet cylinder 16 with a constant pressure. Pressed. Subsequently, the scraper 44 comes into contact with the chute 34 from the outlet cylinder 16, slides on the floor plate 36 from the rear toward the front, and the garbage on the chute 34 is pushed into the storage box 59 (see FIG. 2). Even in that case, the scraper 4
4 rotates relative to the link 42, resistance is added to the rotation and is pressed against the chute 34 with a constant pressure, improving the rate of scraping of dirt. On the other hand, push link 3
2 comes into contact with the operating lever 38, and the chute 34 is held in a horizontal retracted position. In addition, in this embodiment, the damper 5
0 is composed of a fluid pressure cylinder 51 and a speed controller 54, but a mechanical one may also be used. For example, an L-shaped bracket is provided protruding from the link 42, and a spring and pressure contact are made between the bracket and the scraper 44. A member may be interposed to add resistance to the rotation of the scraper 44.

Further, the garbage storage and conveyance device 1 is not limited to one that includes the conveyance screws 8 and 9. As described above, according to the present invention, since the scraper is rotatably connected to the lower part of the gate via the link, the free end of the scraper slides on the chute as the gate is closed.
Since the remaining garbage on the chute can be automatically removed, when the garbage collection vehicle is separated from the chute, the garbage will not fall onto the road surface, and the generation of bad odors can be prevented.

Additionally, if a damper is provided between the link and the scraper to provide resistance to the rotation of the scraper, the scraper will not slide on the chute when the gate is opened.
The dust on the chute is not pushed back, preventing the dust from falling, making it more sanitary, and improving the efficiency of scraping the dust during the closing operation.
