Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a device for opening and closing a bottom door of a garbage basket provided on a water cleaning boat.

[0002]

2. Description of the Related Art A garbage basket provided on a water cleaning boat for collecting floating refuse on the water surface has a structure in which the bottom is opened to discharge garbage contained therein, and a conventional bottom door is manually opened and closed by a locking device. In many cases, it was possible to insert and remove.

[0003]

In the conventional manual opening and closing of the bottom door, the garbage basket itself is subjected to severe use conditions, and when garbage is stored, all the load of the garbage is applied to the bottom door. Since it is loaded, it is difficult to remove the lock, and in many cases, it is forcibly opened with a tool, which is very troublesome and time-consuming.

[0004]

SUMMARY OF THE INVENTION In order to solve the above-mentioned problems, the present invention automatically opens and closes a bottom door of a garbage basket provided on a water cleaning boat, and places the garbage basket on a flat surface when closing. When the bottom door is opened in a state where the dust is stored and dust is stored, the lock can be lightly released by setting the dust load not to be applied to the lock portion.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS The garbage basket bottom door opening / closing device in a water cleaning boat according to the present invention comprises a set of two bottom doors that open downward from the center to the bottom of a box-shaped garbage basket with an open top.
Rollers that roll in contact with a flat surface when the bottom doors are closed are attached to diagonally lower front positions at opposite open end portions of the two bottom doors.

[0006] A pair of bottom door support brackets that support both corners of the opening side end of the bottom door from below when closed are attached to the lower side of the car frame so that one end is rotatable.

A lower end of a lock member having a slender frame shape and protruding lifting projections on both sides near the lower end is rotatably fitted to each of the pair of bottom door support fittings.

A latch for engaging the upper end of the lock member and a lock member guide for restricting the movement of the lock member are fixedly mounted inside the car frame intermediate column above the bottom door support bracket mounting portion.

A lock release window is provided on the side of the car around the intermediate column to which the latch is attached, and a cover wire mesh covering the lock release window and the lock member and the lock member guide is attached to the inner surface of the garbage basket.

When the bottom door is closed, the bottom door hits a lifting projection of the lock member, and the lock member is pushed up to lock the upper end of the bottom member with the latch. The bottom door is held closed.

Embodiments will be described with reference to the drawings.
FIG. 1 is a plan view of the garbage basket of the present invention. FIGS. 2 and 3 show the open / closed state of the bottom door, and FIGS. 4, 5 and 6 show the operation of the lock mechanism of the bottom door.

A rectangular box-shaped garbage basket made entirely of metal has an open upper end face, a mesh of four rounds, and a bottom divided from the center to form a set of two left and right bottom doors 1, 1 with a predetermined interval between flat plates. Are arranged side by side, and each is rotatably attached to the lower side 2 of the cage frame made of pipe. This bottom door 1,
Two rolling rollers 3 are attached diagonally forward and downward at one of the opposed opening side ends.

As shown in FIG. 2, when this rolling roller 3 is lowered with the bottom door 1, 1 opened downward as shown by the phantom line, it rolls in contact with the plane F, so that it rolls. 1 can be easily closed, and since the rolling rollers 3 project obliquely forward and downward from the bottom door 1, the opening ends of the bottom doors 1, 1 when placed on the plane F as shown in FIG. Are lifted slightly above the horizontal so that the bottom doors 1, 1 described below can be unlocked.

Reference numeral 4 denotes a pair of front and rear bottom door support brackets.
The two corners of the open end of the opening 1 are supported from below when closed, and a lock member fitting plate 4a is provided upright at the center of the upper surface, and one end is rotatably supported on the front and rear sides of the lower side of the car frame. .

Reference numeral 5 denotes a lock member, which is formed in an elongated frame shape and has lifting projections 5a protruding on both sides near the lower end, and the lower end is formed at the upper end of a lock member fitting plate 4a which stands upright at the center of the upper surface of the bottom door support bracket. Are rotatably fitted in the holes provided in the holes.

Reference numeral 6 denotes an intermediate column, which is located at the center of the front and rear surfaces of the garbage basket, and has a bottom door support bracket 4 rotatably mounted on the lower side 2 of the car frame over the intermediate column 6. further,
Inside the intermediate pillar 6 above the bottom door support 4, a latch 7 having a latch recess 7 a for latching the upper end of the lock member 5 is fixed.

Reference numeral 8 denotes a lock member guide which is formed by bending a bar into a U-shape as shown in FIGS.
Is disposed so as to pass through the inside of the elongated frame and surround the outside of the hook 7 so that both ends are fixed to the inside of the intermediate pillar 6, and the lower side of the U-shape and the lower part of the front side of the hook 7 are rods. It is connected with wood.

Reference numeral 9 denotes a lock release window, which is a window frame 10 fixed to the car frame lower side 2 and the intermediate column 6 with the latch 7 substantially at the center.
The inside of the window frame 10 has no wire mesh, and as a lock release window 9 in which the intermediate pillar 6 stands in the center, a hand is inserted from the outside, and the upper end of the lock member 5 is fixed as shown in FIG. It is a window to take off from.

Reference numeral 11 denotes a cover wire mesh, and a U-shaped cover frame 12 is attached to the inside near the lower end of the window frame 10, and the cover wire mesh 12 and the wire mesh are attached to the window frame 10 from the side as shown in FIGS. When viewed in a triangular shape, the dust is prevented from leaking from the unlocking window 9 and the movement of the lock member 5 is prevented from being hindered by the dust.

The description of the configuration is completed above, and then the opening and closing operation of the bottom door will be described. The garbage basket for a water surface cleaning boat contains garbage that is immersed in water and floats on the surface of the water, and the garbage basket is lifted at a harbor to be closed horizontally on a pier or a truck as shown in FIG. , 1 are opened downward as shown by the imaginary line to discharge dust.

As shown in FIG. 4, the bottom door 1, 1 has a lock member 5 whose upper end is hung by a hook metal 7, and a bottom door support metal 4 in a normal state. , It is in a horizontal state as shown in FIG.

In order to open the horizontally closed bottom doors 1, 1, a garbage basket is placed on a plane F as shown in FIG.
