Description

  The present invention relates to a dust input box connected to an opening of a dust storage box for storing collected dust, and a dust collecting vehicle including the dust input box, and more particularly, to a gate opening / closing mechanism of a dust input port of the dust input box. The present invention relates to a dust input box and a garbage truck.

  The garbage collection vehicle is equipped with a dust storage box for storing collected dust, and a dust input box is continuously provided at the rear opening thereof. The dust is input from a dust input port provided on the rear surface of the dust input box, and is loaded into the dust storage box by a dust loading device provided in the dust input box. A tailgate is provided at the dust input port so that dust, sewage, and the like are not scattered from the dust input box while the dust collection vehicle is traveling.

  Conventionally, for example, a structure described in Patent Document 1 is known as an opening / closing mechanism for a tailgate of the dust inlet. This gate opening / closing mechanism is applied to a so-called compression-type garbage truck and includes an assist mechanism for reducing the operation force for opening and closing the tailgate. The assist mechanism includes a slide unit provided near the center of the tailgate, an arm having a base end connected to the side wall of the dust bin and a tip end connected to the slide unit, and a tension provided between the side wall and the arm. A coil spring.

  However, the gate opening / closing mechanism of Patent Document 1 has a problem in that there are many parts and the cost is high. In addition, the reduction in operating force for opening and closing the tailgate is limited. Therefore, conventionally, a structure described in Patent Document 2 is known as a technique for reducing the operating force for opening and closing the tail gate as compared with the gate opening / closing mechanism of Patent Document 1. The gate opening / closing mechanism of Patent Document 2 is applied to a so-called rotating plate type garbage truck. This gate opening / closing mechanism has a gate opening / closing arm whose one end is rotatably supported on the side wall of the dust input box and the other end is rotatably supported on both sides of the upper end of the tailgate, and A tension coil spring that connects the side wall and the gate opening / closing arm is provided. In this gate opening / closing mechanism, the other end side of the gate opening / closing arm rotates upward so as to draw a circle around the one end side.

  The tailgate is housed in the upper cover on the rear side of the dust box (inner slide type). In order to make the interior space of the dust box as large as possible and to make the outer shape of the dust box as compact as possible, it is better to match the curved shape of the upper cover and the turning locus of the tailgate to some extent. Therefore, in the gate opening / closing mechanism described in Patent Document 2, the shape of the upper cover is affected by the turning trajectory of the gate opening / closing arm, and the upper portion of the dust box is rounded.

JP 2007-269412 A JP 2008-285317 A

  In the gate opening / closing mechanism described in Patent Document 2, there is a problem that the shape of the upper cover cannot be determined freely, and that the shape of the rear portion of the dust box cannot be freely formed. Therefore, even if an attempt is made to simply replace the gate opening / closing mechanism of Patent Document 1 with the mechanism of Patent Document 2 for a compression garbage truck, the structure of the dust box is greatly different between the compression type and the rotary plate type, which is difficult.

  Further, in the gate opening / closing mechanism described in Patent Document 2, the gate opening / closing arm and the tension coil spring are sequentially arranged in a direction away from the side wall of the dust box. In such a structure, there is no problem when the dust loading device installed in the dust box is a rotary plate type, but in the case of a compression type in which a vertical sliding cylinder is arranged on the side wall, it will be adopted. There is something that is strict in space.

  Therefore, in the present invention, in the inner slide type dust throwing box in which the tailgate is housed in the upper cover on the rear surface of the dust throwing box, it is possible to increase the degree of freedom of the shape of the rear part of the dust throwing box. It is an object of the present invention to provide a dust box having a gate opening / closing mechanism suitable for a dust collector and a dust collector equipped with the same.

  A dust throwing box of the present invention is a dust throwing box having a gate that opens and closes at a dust throwing opening, and a first link arm whose base end is rotatably supported on the side wall of the dust throwing box, and one end that is a gate. A second link arm rotatably supported at the top of the first link arm and the other end of the first link arm rotatably connected to the tip of the first link arm, and one end connected to the upper portion of the side wall of the dust bin, An urging member whose other end is connected to the middle portion of the first link arm, a side wall of the dust throwing box, a guide rail that guides the gate opening and closing track, and rotatably supported on the upper part of the gate; And a roller that rolls in contact with the guide rail.

  In the refuse input box of the present invention, the first link arm whose base end is rotatably supported on the side wall of the dust input box and the second link arm whose one end is rotatably supported on the upper part of the gate are connected. By freely rotating the part, the distance between the support point on the side wall side of the dust input box of the first link arm and the support point on the gate side of the second link arm changes steplessly. Therefore, the degree of freedom of the shape of the guide rail that guides the gate opening / closing track is high, and the upper portion of the gate can be guided by a desired opening / closing track.

  Here, it is desirable that the gate and the second link arm are connected through a guide hole formed in the side wall of the dust box. Thereby, since a side wall can be interposed between a gate and the 2nd link arm, it becomes possible to utilize this side wall for attaching parts, such as a lamp cover.

  In the dust box of the present invention, the guide rail is provided on the inner side of the side wall of the dust box, the bracket provided on the upper back surface of the gate, the bracket, and the guide hole. It is desirable to have a connecting shaft that rotatably supports the roller inside the side wall of the dust box. Thereby, it is possible to prevent the connecting portion between the roller and the gate from being exposed when viewed from the outside of the side wall of the dust box, and it is possible to reduce the protruding portion outside the side wall.

  The urging member is preferably provided at a position overlapping the first link arm as viewed from the outside of the dust inlet. Thereby, since the urging member does not protrude outward from the first link arm, the amount of protrusion outward from the side wall can be reduced.

  In addition, the dust box of the present invention has a cylinder extending in the vertical direction between the side wall of the dust box and the first link arm, and the cylinder is disposed so that the cylinder tube is on the lower side. It is desirable that the side end of the first link arm on the side wall be disposed so as to be positioned above the upper end position of the cylinder tube when the gate is closed. As a result, even if the cylinder and the first link arm are arranged at a position where they overlap each other when viewed from the side of the dust box, the first link arm is always present in the portion of the cylinder rod having a smaller diameter than the cylinder tube. Therefore, the amount of protrusion to the outside of the side wall of the first link arm can be reduced.

Even if the desired shape is determined first, the gate can be opened and closed in accordance with the shape of the rear part of the dust box, and the degree of freedom of the shape of the rear part of the dust box is increased.

(2) Since the gate and the second link arm are connected through a guide hole formed in the side wall of the dust box, the side wall can be used for a mounting portion such as a lamp cover. It becomes possible to form the shape of the rear portion of the charging box more freely.

(3) A guide rail is provided on the inner side of the side wall of the dust box. The bracket is provided on the upper back surface of the gate, and is provided in the bracket and inserted into the guide hole. By having a connecting shaft that is rotatably supported on the inside of the side wall, the connecting part between the roller and the gate is not exposed when viewed from the outside of the side wall of the dust throwing box, and the projecting portion outward from the side wall is reduced. The shape of the rear part of the dust box can be further freely formed.

(4) Since the biasing member is provided at a position overlapping with the first link arm when viewed from the outside of the dust inlet, the biasing member does not protrude outward from the first link arm. In addition, the amount of protrusion to the outside can be reduced, and the shape of the rear part of the dust box can be further freely formed.

(5) A cylinder extending in the vertical direction is provided between the side wall of the dust box and the first link arm, and the cylinder is disposed such that the cylinder tube is on the lower side. The side end on the side wall side of the arm is disposed so as to be positioned above the upper end position of the cylinder tube when the gate is closed, so that the cylinder and the first link arm are connected to the dust container input box. Even if it is arranged at the position overlapped when viewed from the side, the amount of protrusion outward from the side wall of the first link arm can be reduced, and the shape of the rear part of the dust throwing box can be further freely formed Become.
