The frame F is formed so as to surround the drum 2.
ドラム2は、フレームFに回転可能に支持される。ドラム2は、回転軸線AXの回りに、回転方向Rに回転する。実施形態1では、回転方向Rは、塵芥貯留装置1を塵芥の排出側から見たときに、反時計回りを示す。ドラム2の両端部のうちの一方の端部である投入側端部20(第1端部)には、開口OIが形成される。ドラム2には、投入口6aを介して開口OIから塵芥が投入される。ドラム2の両端部のうちの他方の端部である排出側端部22(第2端部)には、開口OEが形成される。開口OEから塵芥が排出される。
The drum 2 is rotatably supported by the frame F. The drum 2 rotates in the rotation direction R around the rotation axis AX. In the first embodiment, the rotation direction R indicates counterclockwise rotation when the dust storage device 1 is viewed from the dust discharge side. An opening OI is formed at the input side end 20 (first end) which is one end of both ends of the drum 2. Dust is introduced into the drum 2 from the opening OI through the insertion port 6a. An opening OE is formed at the discharge side end 22 (second end) which is the other end of the both ends of the drum 2. Dust is discharged from the opening OE.
ドラム2は、断面円形状であり、回転軸線AXに沿った方向において、ドラム2の内径は異なっている。つまり、ドラム2は、胴部2aと、円筒部2bと、テーパー部2cとを含む。胴部2aは、略円筒状であり、回転軸線AXに沿った方向において、胴部2aの内径は略一定である。胴部2aの両端部のうちの一方端部には、円筒部2bが接合される。円筒部2bは、略円筒状であり、回転軸線AXに沿った方向において、円筒部2bの内径は略一定である。円筒部2bの内径は、胴部2aの内径よりも小さい。胴部2aの両端部のうちの他方端部には、テーパー部2cが接合される。テーパー部2cは、中空の略円錐台状であり、回転軸線AXに沿った方向において、テーパー部2cの内径は異なっている。
The drum 2 has a circular cross section, and the inner diameter of the drum 2 is different in the direction along the rotation axis AX. That is, the drum 2 includes a body portion 2a, a cylindrical portion 2b, and a tapered portion 2c.

The chain 4 is bridged between a large-diameter sprocket formed on the outer peripheral surface of the cylindrical portion 2b and a small-diameter sprocket connected to the rotating shaft of the motor. Then, by rotating the motor, the drum 2 rotates in the rotation direction R via the small diameter sprocket, the chain 4, and the large diameter sprocket. When the drum 2 rotates in the rotation direction R, the dust thrown into the drum 2 is moved from the closing portion 6 toward the discharge-side lid portion 11 by the plurality of blade members formed inside the drum 2, and the discharge side Pressed against the lid 11. As a result, the dust is compressed and stored in the drum 2. The large-diameter sprocket, the motor, the small-diameter sprocket, and the plurality of blade members are not shown for simplification of the drawing. Moreover, the discharge side cover part 11 is shown with the dashed-two dotted line for simplification of drawing.
閉塞部6は、フレームFの両端部のうちの一方端部に取り付けられる。閉塞部6は、ドラム2の投入側端部20に形成された開口OIの一部を塞ぐ。閉塞部6には、塵芥をドラム2に投入するための投入口6aが形成される。
The closing portion 6 is attached to one end portion of both ends of the frame F. The closing part 6 closes a part of the opening OI formed in the charging side end part 20 of the drum 2. The closing part 6 is formed with an input port 6 a for supplying dust to the drum 2.
投入側蓋部7は投入口6aを塞ぐ。投入側蓋部7は、投入口6aを塞ぐ閉位置と投入口6aを露出させる開位置との間を移動する。
The charging side lid portion 7 closes the charging port 6a. The charging side lid portion 7 moves between a closed position where the charging port 6a is closed and an open position where the charging port 6a is exposed.
シール部8は、ドラム2の投入側端部20と閉塞部6との間をシーリングする。
The seal portion 8 seals between the closing side portion 20 and the closing portion 6 of the drum 2.

The wall 10 is attached to the other end of both ends of the frame F. The wall portion 10 faces the closing portion 6. The wall 10 is formed with a substantially circular insertion port 10a. The discharge side end 22 of the drum 2 is inserted into the insertion port 10a. Accordingly, the discharge side end portion 22 protrudes from the insertion port 10a.
排出側蓋部11は開口OEを塞ぐ。排出側蓋部11は、開口OEを塞ぐ閉位置と開口OEを露出させる開位置との間を移動する。ドラム2に貯留された塵芥を排出するときは、排出側蓋部11が開位置に移動され、開口OEが露出する。そして、ドラム2が回転方向Rに回転すると、塵芥は、ドラム2の内部に形成された複数の羽根部材によって、開口OEからドラム2の外部へ排出される。
The discharge side lid 11 closes the opening OE. The discharge-side lid 11 moves between a closed position that closes the opening OE and an open position that exposes the opening OE. When the dust stored in the drum 2 is discharged, the discharge-side lid 11 is moved to the open position, and the opening OE is exposed. When the drum 2 rotates in the rotation direction R, the dust is discharged from the opening OE to the outside of the drum 2 by a plurality of blade members formed inside the drum 2.

FIG. 3 is an enlarged perspective view showing the positioning portion 18. As shown in FIG. 3, the positioning part 18 includes a restriction part 30 and a flange part 32. The restricting portion 30 is an annular shape and is a plate-like member that protrudes from the back surface 6 b of the closing portion 6. The flange portion 32 is an annular shape, and is a plate-like member that extends from the front end portion of the restriction portion 30 along the back surface 6 b of the closing portion 6. The flange portion 32 and the restricting portion 30 form a substantially right angle.
また、閉塞部6には、規制部34と、規制部36とが形成される。規制部34は、閉塞部6の裏面6bから突出しており、円環状の板状の部材である。規制部34の直径は、規制部30の直径よりも小さい。規制部36は、閉塞部6の裏面6bから突出しており、円環状の板状の部材である。規制部36の直径は、規制部34の直径よりも小さい。規制部34及び規制部36は、ドラム2の径方向への移動を規制する。
Further, a restriction part 34 and a restriction part 36 are formed in the closing part 6. The restricting portion 34 protrudes from the back surface 6b of the closing portion 6 and is an annular plate-shaped member. The diameter of the restriction part 34 is smaller than the diameter of the restriction part 30. The restricting portion 36 protrudes from the back surface 6b of the closing portion 6 and is an annular plate-shaped member. The diameter of the restricting portion 36 is smaller than the diameter of the restricting portion 34. The restricting portion 34 and the restricting portion 36 restrict the movement of the drum 2 in the radial direction.
図4及び図5を参照して、シール部8の詳細について説明する。図4は、シール部8を示す断面斜視図である。図5は、シール部8を示す断面図である。図4及び図5では、円環状のシール部8の最下部近傍が示される。図4及び図5に示すように、パッキン16は、ドラム2の投入側端部20の外周面21と規制部30とに挟まれるとともに、押圧部14とドラム2の突出部12とに挟まれている。具体的には、次の通りである。
Details of the seal portion 8 will be described with reference to FIGS. FIG. 4 is a cross-sectional perspective view showing the seal portion 8. FIG. 5 is a cross-sectional view showing the seal portion 8. 4 and 5, the vicinity of the lowermost portion of the annular seal portion 8 is shown. As shown in FIGS. 4 and 5, the packing 16 is sandwiched between the outer peripheral surface 21 of the charging-side end portion 20 of the drum 2 and the regulating portion 30, and is sandwiched between the pressing portion 14 and the protruding portion 12 of the drum 2. ing. Specifically, it is as follows.
パッキン16は、ドラム2の投入側端部20の外周面21に沿って配置される。規制部30は、閉塞部6の裏面6bから、ドラム2の回転軸線AX(図2)に沿って突出している。規制部30は、パッキン16よりも、ドラム2の径方向Aの外側に配置され、径方向Aへのパッキン16の移動を規制する。規制部30は、パッキン16を介してドラム2の投入側端部20の外周面21に対向している。ドラム2の投入側端部20の外周面21は、規制部30に向かってパッキン16を押圧する。
The packing 16 is disposed along the outer peripheral surface 21 of the charging side end 20 of the drum 2. The restricting portion 30 protrudes from the back surface 6 b of the closing portion 6 along the rotation axis AX (FIG. 2) of the drum 2. The restricting portion 30 is disposed outside the packing 16 in the radial direction A of the drum 2 and restricts the movement of the packing 16 in the radial direction A. The restricting portion 30 faces the outer peripheral surface 21 of the charging side end portion 20 of the drum 2 through the packing 16. The outer peripheral surface 21 of the input side end portion 20 of the drum 2 presses the packing 16 toward the restriction portion 30.
フランジ部32は、規制部30に形成され、押圧部14と対向する。具体的には、フランジ部32は、規制部30の先端部からドラム2の径方向Aに延びている。つまり、位置決め部18は断面略L字状である。また、突出部12は、ドラム2の投入側端部20の外周面21から、ドラム2の径方向Aに突出する。
The flange portion 32 is formed in the restricting portion 30 and faces the pressing portion 14. Specifically, the flange portion 32 extends in the radial direction A of the drum 2 from the distal end portion of the restriction portion 30. That is, the positioning part 18 has a substantially L-shaped cross section. Further, the protruding portion 12 protrudes in the radial direction A of the drum 2 from the outer peripheral surface 21 of the charging side end portion 20 of the drum 2.
押圧部14は、ドラム2の径方向Aの外側に配置され、パッキン16と対向する。押圧部14は、パッキン16を介して、突出部12と対向する。押圧部14とフランジ部32とは連結される。具体的には、押圧部14とフランジ部32とにボルト25を貫通させ、ナット27をボルト25に螺合することによって、押圧部14を締め付ける。その結果、押圧部14は、ドラム2の突出部12に向かってパッキン16を押圧する。具体的には、押圧部14は、各々が断面略円形状の複数の凸部14aを含む。実施形態1では、2つの凸部14aが設けられる。凸部14aは、パッキン16に向かって突出し、パッキン16に沿って延びる円環状の部材である。凸部14aは、突出部12に向かってパッキン16を押圧する。
The pressing portion 14 is disposed outside the radial direction A of the drum 2 and faces the packing 16. The pressing portion 14 faces the protruding portion 12 through the packing 16. The pressing part 14 and the flange part 32 are connected. Specifically, the pressing portion 14 is tightened by passing the bolt 25 through the pressing portion 14 and the flange portion 32 and screwing the nut 27 into the bolt 25. As a result, the pressing portion 14 presses the packing 16 toward the protruding portion 12 of the drum 2. Specifically, the pressing portion 14 includes a plurality of convex portions 14a each having a substantially circular cross section. In the first embodiment, two convex portions 14a are provided. The convex portion 14 a is an annular member that protrudes toward the packing 16 and extends along the packing 16. The convex portion 14 a presses the packing 16 toward the protruding portion 12.
図4~図7を参照して、シール部8と一般的なシール部102とを比較して説明する。図6は、一般的な塵芥貯留装置100のシール部102を示す断面斜視図である。図7は、シール部102を示す断面図である。図6及び図7に示すように、一般的な塵芥貯留装置100は、シール部102、ドラム104、及び投入側閉塞部106を備える。シール部102は、パッキン108、溝部110、及び押圧部112を含む。
Referring to FIG. 4 to FIG. 7, the seal portion 8 and the general seal portion 102 will be described in comparison. FIG. 6 is a cross-sectional perspective view showing a seal portion 102 of a general dust storage device 100. FIG. 7 is a cross-sectional view showing the seal portion 102. As shown in FIGS. 6 and 7, the general dust storage device 100 includes a seal portion 102, a drum 104, and a closing side blocking portion 106. The seal part 102 includes a packing 108, a groove part 110, and a pressing part 112.
パッキン108は円環状である。溝部110は、投入側閉塞部106の裏面106aに円環状に形成される。溝部110には、パッキン108が嵌め込まれる。溝部110及びパッキン108は、ドラム104の投入側端部116の内周面116aよりも、ドラム104の回転軸線に近い側に設けられる。
The packing 108 has an annular shape. The groove 110 is formed in an annular shape on the back surface 106 a of the closing side portion 106. The packing 108 is fitted into the groove 110. The groove part 110 and the packing 108 are provided on the side closer to the rotation axis of the drum 104 than the inner peripheral surface 116 a of the charging side end part 116 of the drum 104.
押圧部112は、断面略L字状の部材であり、円環状に形成される。押圧部112は、パッキン108と対向し、ドラム104の投入側端部116の内周面116aよりも、ドラム104の回転軸線に近い側に設けられる。一方、ドラム104には、円環状の内壁部104aが形成される。内壁部104aは、ドラム104の内周面116aから、溝部110向かって起立する板状の部材である。内壁部104aと押圧部112とはボルト114によって連結され、押圧部112はボルト114に締め付けられる。その結果、押圧部112は、投入側閉塞部106に向かってパッキン108を押圧する。
The pressing portion 112 is a member having a substantially L-shaped cross section and is formed in an annular shape. The pressing portion 112 faces the packing 108 and is provided on the side closer to the rotation axis of the drum 104 than the inner peripheral surface 116 a of the charging side end portion 116 of the drum 104. On the other hand, the drum 104 has an annular inner wall portion 104a. The inner wall portion 104 a is a plate-like member that stands up from the inner peripheral surface 116 a of the drum 104 toward the groove portion 110. The inner wall portion 104 a and the pressing portion 112 are connected by a bolt 114, and the pressing portion 112 is fastened to the bolt 114. As a result, the pressing part 112 presses the packing 108 toward the closing side blocking part 106.
押圧部112によってパッキン108を押圧することによって、ドラム104から汚水等の汚液が漏洩することを抑止する。しかしながら、塵芥を圧縮したり、塵芥を排出したりする場合、ドラム104が、投入側閉塞部106から排出側壁部に向かう方向Bに僅かに移動する場合がある。この場合、押圧部112はドラム104の内壁部104aに連結されているため、押圧部112はドラム104とともに方向Bに僅かに移動する。その結果、押圧部112からパッキン108への押圧力が低下し、パッキン108が効果的に機能しない場合がある。
By pressing the packing 108 with the pressing portion 112, leakage of sewage such as sewage from the drum 104 is suppressed. However, when compressing the dust or discharging the dust, the drum 104 may move slightly in the direction B from the closing block 106 toward the discharge side wall. In this case, since the pressing portion 112 is connected to the inner wall portion 104 a of the drum 104, the pressing portion 112 moves slightly in the direction B together with the drum 104. As a result, the pressing force from the pressing portion 112 to the packing 108 decreases, and the packing 108 may not function effectively.
これに対して、実施形態1によれば、図4及び図5を参照して説明したように、ドラム2には突出部12が形成されており、ドラム2が、閉塞部6から壁部10に向かう方向Bに移動した場合、突出部12も方向Bに移動する。従って、突出部12は押圧部14に向かってパッキン16を押圧し、パッキン16に加えられる押圧力が大きくなる。その結果、パッキン16は、ドラム2が方向Bに移動していない場合よりも、突出部12に密着する。つまり、パッキン16がドラム2を効果的に密閉する。その結果、塵芥が貯留されるドラム2から、汚水等の汚液が漏洩することを効果的に抑止できる。
On the other hand, according to the first embodiment, as described with reference to FIGS. 4 and 5, the protrusion 2 is formed on the drum 2, and the drum 2 extends from the closing portion 6 to the wall portion 10. When moving in the direction B toward, the protrusion 12 also moves in the direction B. Therefore, the protruding portion 12 presses the packing 16 toward the pressing portion 14, and the pressing force applied to the packing 16 increases. As a result, the packing 16 is more closely attached to the protruding portion 12 than when the drum 2 is not moving in the direction B. That is, the packing 16 effectively seals the drum 2. As a result, it is possible to effectively prevent leakage of sewage such as sewage from the drum 2 where dust is stored.
また、実施形態1によれば、パッキン16は、ドラム2の外周面21によって、規制部30に向かって押圧されている。従って、ドラム2が方向Bに移動した場合であっても、ドラム2の外周面21からパッキン16への押圧力が低下することを抑制できる。その結果、パッキン16がドラム2を更に効果的に密閉し、ドラム2から汚液が漏洩することを更に効果的に抑止できる。
Further, according to the first embodiment, the packing 16 is pressed toward the regulating portion 30 by the outer peripheral surface 21 of the drum 2. Therefore, even when the drum 2 moves in the direction B, it is possible to suppress the pressing force from the outer peripheral surface 21 of the drum 2 to the packing 16. As a result, the packing 16 can more effectively seal the drum 2, and the leakage of dirty liquid from the drum 2 can be further effectively prevented.
さらに、実施形態1によれば、ドラム2の外周面21が規制部30に向かってパッキン16を押圧していることに加えて、押圧部14が突出部12に向かってパッキン16を押圧している。その結果、パッキン16がドラム2を更に効果的に密閉し、ドラム2から汚液が漏洩することを更に効果的に抑止できる。
Furthermore, according to the first embodiment, in addition to the outer peripheral surface 21 of the drum 2 pressing the packing 16 toward the restricting portion 30, the pressing portion 14 presses the packing 16 toward the protruding portion 12. Yes. As a result, the packing 16 can more effectively seal the drum 2, and the leakage of dirty liquid from the drum 2 can be further effectively prevented.
さらに、実施形態1によれば、押圧部14は、フランジ部32に連結されており、ドラム2に連結されていない。従って、ドラム2が方向Bに移動した場合であっても、押圧部14からパッキン16への押圧力が低下することを抑制できる。その結果、パッキン16がドラム2を更に効果的に密閉し、ドラム2から汚液が漏洩することを更に効果的に抑止できる。
Furthermore, according to the first embodiment, the pressing portion 14 is connected to the flange portion 32 and is not connected to the drum 2. Therefore, even when the drum 2 moves in the direction B, it is possible to suppress a decrease in the pressing force from the pressing portion 14 to the packing 16. As a result, the packing 16 can more effectively seal the drum 2, and the leakage of dirty liquid from the drum 2 can be further effectively prevented.
さらに、実施形態1によれば、押圧部14は、凸部14aによってパッキン16を押圧している。従って、パッキン16への単位面積当たりの押圧力を大きくできる。その結果、パッキン16がドラム2を更に効果的に密閉し、ドラム2から汚液が漏洩することを更に効果的に抑止できる。
Furthermore, according to Embodiment 1, the pressing part 14 is pressing the packing 16 by the convex part 14a. Therefore, the pressing force per unit area to the packing 16 can be increased. As a result, the packing 16 can more effectively seal the drum 2, and the leakage of dirty liquid from the drum 2 can be further effectively prevented.
さらに、実施形態1によれば、ドラム2には、円環状の内壁部23が形成される。内壁部23は、ドラム2の投入側端部20の内周面29から起立する板状の部材である。内壁部23を形成することによって、ドラム2から塵芥が漏洩することを更に抑制できる。
Furthermore, according to the first embodiment, the drum 2 is formed with an annular inner wall portion 23. The inner wall portion 23 is a plate-like member that rises from the inner peripheral surface 29 of the charging side end portion 20 of the drum 2. By forming the inner wall portion 23, it is possible to further suppress the leakage of dust from the drum 2.
さらに、実施形態1によれば、図1~図3に示すように、塵芥貯留装置1は、シール部8の下方に、傾斜している樋40をさらに備えている。従って、仮に、ドラム2の投入側端部20から、汚液が漏洩したとしても、樋40によって汚液を汚液溜めに案内できる。その結果、汚液によって、塵芥貯留装置1及びその周囲環境が汚染されることを抑制できる。
Furthermore, according to the first embodiment, as shown in FIGS. 1 to 3, the dust storage device 1 further includes a sloping gutter 40 below the seal portion 8. Therefore, even if spilled liquid leaks from the input side end 20 of the drum 2, the spilled liquid can be guided to the sewage reservoir by the gutter 40. As a result, it is possible to prevent the dust storage device 1 and the surrounding environment from being contaminated by the dirty liquid.
(実施形態2)
図8~図10を参照して、本発明の実施形態2に係る塵芥貯留装置1について説明する。実施形態2に係る塵芥貯留装置1の構成は、実施形態1に係る塵芥貯留装置1の構成と同様である。ただし、図8に示すように、実施形態2に係る塵芥貯留装置1は、実施形態1に係る塵芥貯留装置1の構成に加えて、突起部15をさらに含む。以下、実施形態2が実施形態1と異なる点を主に説明する。 (Embodiment 2)
