The rear end wall 10a of the drum 10 is closed, and a support shaft 15 protruding from the rear end wall 10a is rotatably supported by a bearing 16 of a support base 17.

A helical blade 19 is fixed to the inner circumferential wall of the drum 10, and as the drum 10 rotates, the helical blade 19 sends garbage in the direction of the axis OO within the drum.

An opening is formed in the front end wall 10b of the drum 10, and a garbage input/discharge device 20 is provided within this opening. The garbage input/discharge device 20 has a single case-shaped outer shell 21, and this outer shell 21 is fixed to a frame 23 fixed in front of the front end wall 10b of the drum 10. It is also designed not to rotate along with it.

The outer shell 21 integrally has a partition wall 24 at its rear, and also has an opening 25 at its lower end and an opening 26 at its upper end. On the other hand, a garbage input and discharge opening (hereinafter simply referred to as an opening) 28 is provided at the center of the front end of the outer shell 21.

A garbage input passage 30 is provided obliquely downward and rearward from the opening 28 toward the opening 25. To form this passage 30, an inclined wall 33 is provided in the outer shell 21.

The opening 28 is opened and closed by a discharge port large lid 41. The large lid 41 has a small charging lid 42 that can be opened and closed, and is slidable up and down along a guide 43, as shown in FIGS. 2 and 4.

Next, the operation of the garbage storage device described above will be explained.

When garbage is input, the discharge port large lid 41 is closed as shown in FIGS. 1 and 2, and the first
As shown, the lower panel 37 of the input and output device 20 is in an open position and the upper panel 39 is in a closed position. In this state, when the small input lid 42 is opened and garbage is input, the garbage slides down and rearward inside the garbage input passage 30 and reaches the bottom of the drum 10 through the opening 25. Therefore, the motor M is operated to send the garbage to the rear of the drum by the spiral blade 19.

When the garbage stored in the panel 10 becomes full in this way, the garbage is discharged. In this case, the discharge port large lid 41 is raised as shown in FIGS. 3 and 4. to open the opening 28, and then open the lower panel 37 as shown in FIG.
to the closed position and the top panel 39 to the open position. In this state, when the motor M is reversed and the garbage inside the drum 10 is sent in the direction of the input/discharge device 20 by the spiral blade 19, the wide scraping blade 19a rotating around the spiral blade 19 moves the garbage above the opening 26. The scraped up dirt slides down inside the dirt discharge passage 31 from the opening 26 and is discharged to the outside from the opening 28. Therefore, by applying the tailgate G of the garbage collection vehicle to the opening 28 as shown, the garbage is sent into the table gate. At this time, there is no need to further interpose a conveying device such as a belt conveyor in the opening 28.

As shown in FIGS. 1 and 3, it is preferable that the upper and lower panels 39, 37 be rotated between the two positions in conjunction with the opening and closing operations of the outlet large cover 41. For this reason, the interlocking mechanism is
