Description

[Detailed Description of the Invention] (Field of Industrial Application) [0001] The present invention relates to a refuse collection vehicle, and more particularly to a sealing structure of a joint portion where a refuse storage box and a refuse input box are joined.

(Prior Art) FIG. 3 shows a conventional garbage truck.

In FIG. 3, a is a dust storage box mounted on a vehicle frame, and a dust throwing box b having an open front surface is rotatably connected to a rear opening of the dust storage box a about a pivot axis c.
On the side of the dust throwing box b, a tilting cylinder d is provided continuously between the upper part of the dust throwing box a and the lower part of the dust throwing box b, and the dust throwing box b is moved by the expansion and contraction operation of the tilting cylinder d. The rear opening of the dust storage box a is opened and closed by tilting upward. Further, a seal piece e is formed on the peripheral edge of the front opening of the dust throwing box b from the lower end edge and the lower ends of the side edges to the middle thereof, and the seal member f is disposed on the seal piece e to dispose of the dust. The joint between the storage box a and the dust input box b is sealed.

(Problems to be solved by the invention) However, in the conventional dust collecting vehicle, if the seal piece e is extended to the upper side edge, the upper end of the seal piece e is tilted when the dust throwing box b is rotated. Therefore, the sealing piece e can extend upward from the lower end of the side edge to about ½ at most, and as a result, the sealing member f
Therefore, the sealing of the joint between the dust storage box a and the dust input box b is up to that position, and there is a problem that sewage leaks from the unsealed upper part.

(Means for Solving the Problem) The dust collecting vehicle of the present invention is a dust collecting vehicle in which a dust throwing box is connected to a rear opening of a dust storing box mounted on a vehicle frame so as to be tiltable by a tilting cylinder. At the joint between the dust storage box and the dust throwing box, a sealing member is arranged in an upward U-shape at the lower end edge and both side edges of the joint, and a seal provided at the side edge. The member is arranged at an upper position of at least ½ or more of the length of the side edge, while the tilting cylinder is arranged at a position where it does not come into contact with the sealing member when the dust throwing box is tilted. It will be.

(Operation) A seal member is arranged in an upward U-shape at the lower end edge of the joint between the dust storage box and the dust input box, and both side edges, and the side edge seal member has a length equal to that of the side edge. On the other hand, the tilting cylinder should be installed at least up to one-half or more of the upper position, and should be installed between the upper part of the dust container and the upper part of the dust throwing box and at a position where it does not interfere with the sealing member when the dust throwing box is tilted. Then, the joint between the dust storage box and the dust throwing box is sealed to the upper side of the side to prevent leakage of dirty water and the like from the inside.

Embodiment An embodiment of the present invention will be described below with reference to the drawings.

FIG. 1 shows a garbage truck according to the present invention.

In the figure, reference numeral 1 is a dust container box mounted on a vehicle frame of the dust truck. At the rear opening of the dust storage box 1, a dust input box 2 having an open front surface is continuously connected so as to be able to tilt upward with a pivot 3, and a tilting cylinder arranged at a side of the dust input box 2. The dust throwing box 2 is tilted by the expansion and contraction operation of 5, and the rear opening of the dust storing box 1 can be opened and closed. Further, a dust loading device (not shown) is installed in the dust loading box 2, and the dust loading device loads the dust loaded from the loading port provided at the lower rear portion of the dust loading box 2 into the dust loading box 1. It is configured to be pushed in.

The tilting cylinder 5 has a base end connected to an upper part of a side surface of the dust container 1 and a tip end of a rod connected to an upper part of a side surface of the dust input box 2 to be disposed on an upper part of a side surface of the dust input box 2. Has been done.

Further, as shown in FIG. 2, when the dust throwing box 2 closes a rear opening of the dust throwing box 2, the dust throwing box 2 is joined to the peripheral edge portion 2a of the dust throwing box 2 with the dust throwing box 1. A seal piece 6 is formed. The sealing piece 6 is formed continuously from the lower end of the peripheral edge portion 2a and the lower ends of both side edges upward, and the upper end of the sealing piece 6 interferes with the tilting cylinder 5 when the dust throwing box 2 is rotated. Do not perimeter
More than half of both side edges of 2a (about 2/3 in this example)
Has been extended to the position above. A seal member 7 is arranged in a substantially U shape along the seal piece 6, and the seal member 7 seals the joint between the dust storage box 1 and the dust input box 2 to prevent leakage of dirty water from the inside. To prevent.

By disposing the tilting cylinder 5 in this way, the tilting cylinder 5 does not interfere even if the seal piece 6 is extended from the lower end of the side edge of the peripheral edge portion 2a to an upper position of about two-thirds. .
That is, the seal member 7 can be extended to that position, and the seal of the joint between the dust container 1 and the dust throwing box 2 can be extended to the upper side edge as much as possible.

(Effects of the Invention) As described above, according to the present invention, by extending the seal at the joint between the dust storage box and the dust input box upward by more than half, the leakage of sewage from the inside. The prevention effect can be enhanced.
