JP 2016-78616 A

In the passenger management machine described above, a boarding and alighting opening and a door for opening and closing the boarding and alighting opening are provided on the lateral side of the cabin. It must be provided between the cabin and the drug spraying arm in the retracted posture, and the wider the gap, the wider the width of the riding maintenance machine set by the drug spraying arm in the retracted posture. However, if the space between the chemical spraying arm in the stowed position and the cabin becomes narrower, it is easier for the user to push the chemical spraying arm to secure a passage when getting on or off the boarding-type operation unit, or to touch the chemical spraying arm with the body. The chemical spray arm becomes easily damaged.

To provide a riding tending machine in which the width of the riding tending machine set by a chemical spraying arm in a retracted posture is narrowed while the chemical spraying arm can be repaired or replaced inexpensively.

A passenger management machine according to the present invention comprises a traveling machine body having a boarding-type operation section equipped with a cabin, and a working posture provided on both lateral sides of the traveling machine body and protruding laterally outward of the traveling machine body. , a retracted posture positioned in a state extending in the longitudinal direction of the traveling machine body passing through the lateral side of the cabin in the longitudinal direction inside the traveling machine body in the lateral width direction of the traveling machine body relative to the working posture; a pair of drug spraying arms, and a boarding port and a door for opening and closing the boarding port are provided only on one of the left lateral side and the right lateral side of the cabin. The door moves along the front-rear direction of the traveling machine body between a closed position and an open position, and the door is not provided in the left lateral side portion and the right lateral side portion of the cabin. A storage stand is provided on one lateral side .

According to this configuration, the door moves along the front-rear direction of the traveling machine body and changes its position between the open position and the closed position. , the distance between the cabin and the drug spraying arm in the retracted posture can be narrowed, and the width of the riding maintenance machine set by the drug spraying arm in the retracted posture can be narrowed. As a result of narrowing the gap between the cabin and the chemical spraying arm in the retracted posture, even if the chemical spraying arm is damaged by getting on and off the operation part, the chemical spraying arm on the side of the pair of left and right chemical spraying arms where the entrance/exit is located will be able to spray the chemical. Since only the arm is damaged, even if the chemical spraying arm needs to be repaired or replaced, only the chemical spraying arm on the side where the entrance/exit is located can be repaired or replaced at a low cost.
In addition, according to this configuration, there is no entrance/exit above the storage stand, so there is no problem even if an article that is vertically large is placed on the storage stand.

In the present invention, it is preferable that a drug tank for storing the drug sprayed by the drug spraying arm is provided at the rear part of the traveling machine body, and the open position of the door is positioned forward of the closed position. be.

According to this configuration, there is no need to avoid contact between the door located in the open position and the chemical tank, and the width of the door movement space provided on the lateral outside of the cabin can be narrowed, so chemical spraying between the cabin and the stored position is possible. The gap between the arms can be made narrower.

In the present invention, it is preferable that the front portion of the medicine tank is formed with a recessed portion into which the rear portion of the ride-on operation portion is inserted.

According to this configuration, while the lateral side of the rear part of the boarding-type operation unit is utilized as the installation space for the chemical tank, there is no need to avoid contact between the door located at the open position and the chemical tank, so the cabin is improved. and the medicine spraying arm in the retracted posture can be narrowed.

In the present invention, a link mechanism that swingably extends from the frame of the cabin, has an extending end that is swingably connected to the door, and supports the door movably along the longitudinal direction. is preferably provided.

According to this configuration, the door is supported by the link mechanism and moves along the front-rear direction of the traveling body by the action of the link mechanism. Therefore, there is no need to provide a guide rail, and the movement path of the door is not clogged with soil or sand. problems do not occur.

In the present invention, the link mechanism has a front swing link and a rear swing link arranged in the front-rear direction of the door in a plan view, and the front swing link is provided in two upper and lower stages. It is preferable that only one stage of the rear swing link is provided.

According to this configuration, the structure of the link mechanism can be made simple with only three links.

In the present invention, it is preferable that a connecting rod extending vertically of the fuselage is provided for connecting middle portions of the front swing links of the upper and lower two stages, and a handle portion for opening and closing the door is formed on the connecting rod. be.

According to this configuration, the opening/closing operation force applied to the handle is efficiently transmitted to the upper and lower swing links, so that the door can be opened and closed smoothly and lightly.

In the present invention, it is preferable that a chemical tank for storing the chemical sprayed by the chemical spraying arm is provided, and the storage table is equipped with a band for fixing a pump for supplying water to the chemical tank to the storage table. be.

According to this configuration, since the pump can be fixed to the storage stand and held at all times, it is convenient to supply water to the chemical tank by the pump even from a water source such as a river or a pond.

In the present invention, a washer tank for storing a cabin cleaning liquid is provided outside the left side portion and the right side portion of the cabin, which is not provided with the entrance/exit. It is preferable to have

According to this configuration, the washer tank can be easily handled from the lateral outer side of the machine body, so it is easy to supply liquid to the washer tank.
In the present invention, a fuel tank for an engine is provided on one of the left side portion and the right side portion of the cabin where the entrance is not provided,
It is preferable that the filler port of the fuel tank is positioned laterally outward of the fuselage with respect to the side portion on which the entrance/exit is not provided, and the storage stand is provided above the fuel tank.
According to this configuration, there is no need to provide an entry/exit step above the fuel tank, which tends to obstruct fuel supply to the fuel tank, so fuel can be easily supplied to the fuel tank.
In addition, according to this configuration, there is no entrance/exit above the storage stand, so there is no problem even if an article that is vertically large is placed on the storage stand. In addition, even if an article is placed on the storage stand, the weight of the article is not applied to the fuel tank, so the storage stand is easy to use.
