  In the prior art described above, there is a possibility that the direction of the moment due to the mass of the movable structure including the link device and the belt conveyor device arranged on the main body may change due to the tilt of the belt conveyor device accompanying the operation of the link device. Due to this changed moment, there is a concern that the cylinder forming the link device may escape to the stroke end. Such a runaway of the cylinder causes an unintended change in the attitude of the belt conveyor device, leading to a decrease in workability of work performed via the belt conveyor device.

  Further, in order to prevent such a cylinder from running away, a special device such as a runaway prevention valve is required, which causes a problem that the manufacturing cost increases.

  The present invention has been made from the above-described actual state of the prior art, and its purpose is to determine the direction of the moment due to the mass of the movable structure including the support member and the conveyor device arranged in the main body until reaching the working posture. It is to provide a self-propelled conveyor that can always be kept in one direction.

  In order to achieve this object, the present invention provides a traveling body, a main body disposed on the traveling body and mounted with a power chamber, a conveyor device disposed above the main body, and one end of the first pin. A self-propelled conveyor comprising a support member that is pivotally connected to the main body via a second end and is pivotally connected to the conveyor device via a second pin to support the conveyor device. Until the working posture, the center of gravity of the movable structure including the support member disposed on the main body and the conveyor device is present on one side with respect to the vertical line passing through the first pin. Further, the movable structure is arranged.

  The present invention configured as described above can run while the conveyor device is held by driving the running body, and the conveyor device can be moved up and down and tilted by rotating the support member. it can. Moreover, a conveyed product can be conveyed to a predetermined place by the drive of a conveyor apparatus. In particular, for example, the position of the center of gravity of the movable structure is relative to the vertical line passing through the first pin until the working posture, such as a posture in which one of the conveyor devices is lowered and the other is raised to work. Since it exists on one side, the direction of the moment due to the mass of the movable structure can always be kept in one direction. Thereby, the change of the attitude | position which the conveyor apparatus does not intend can be prevented.

  In the present invention, the power chamber is mounted in the vicinity of one end of the main body, the first pin is disposed in the vicinity of the other end of the main body, and the support member is mounted in the power chamber. The movable structure is arranged such that the center of gravity of the movable structure exists between the vertical line passing through the first pin and the power chamber. It is said.

  Further, the present invention is the above invention, wherein one end is pivotally connected to the main body, the other end is pivotally connected to the support member, and is inclined and arranged in a direction approaching the power chamber.

  Further, the present invention is the above invention, wherein the power chamber is mounted in the vicinity of one end of the main body, the first pin is disposed at a position close to the power chamber, and the support member is separated from the power chamber. The movable structure is arranged so as to be inclined in a direction away from the movable structure so that the center of gravity of the movable structure exists between the vertical line passing through the first pin and the other end of the main body. It is characterized by that.

  Further, the present invention is the above invention, wherein one end is pivotally connected to the main body, the other end is pivotally connected to the support member, and is inclined and arranged in a direction away from the power chamber. A first guide cylinder that can be pivoted and one end pivotally connected to the main body, the other end pivotally coupled to the first guide cylinder, and a first guide cylinder that is inclined in a direction away from the power chamber.

A cylinder, and a second cylinder, one end of which is rotatably connected to the support member, and the other end of which is rotatably connected to the second guide cylinder and is inclined in a direction approaching the power chamber. It is characterized by having prepared.

  In the present invention, until reaching the working posture, the center of gravity of the movable structure including the support member and the conveyor device disposed on the main body passes through the first pin that rotatably connects the support member to the main body. Since the movable structure is arranged so that it is on one side of the line, the direction of the moment due to the mass of the movable structure can always be kept in one direction, which has been a concern in the past. Therefore, it is possible to prevent an unintended change in the attitude of the conveyor device due to a change in the orientation of the conveyor device, and it is possible to prevent a decrease in workability due to such an unintended change in the attitude of the conveyor device. Moreover, since a special device including a runaway prevention valve or the like is not required, an increase in production cost can be suppressed.
