JP, 2016-220552, A

  When the grass collecting device is removed from the vehicle body, by artificially adjusting the position of the support cart with respect to the vehicle body, the grass collection device that has been removed from the vehicle body is placed on the support cart in a good condition (as designed). In order to do so, the place where the support cart should be placed is set, so that it takes time to adjust the position of the support cart and it takes time to remove the grass collecting device.

  The present invention provides a support trolley and a riding-type mower that can quickly remove a grass collection device while allowing the grass collection device removed from the vehicle body to be properly placed on the support dolly.

The support carriage according to the present invention is
A grass cutting device provided on the vehicle body, a support mechanism detachably supported on the rear portion of the vehicle body, and a grass collection container supported by the support mechanism and supplied with and storing the mowing grass obtained by the grass cutting device. A supporting trolley for use in attaching and detaching the grass-collecting device to and from a riding-type mower equipped with the grass-collecting device, the base part being movable on a work floor, and the base part. And a positioning portion that is provided in the front portion of the base portion and that is removably engaged with the vehicle body from the rear. When the positioning portion is engaged with the vehicle body, the positioning portion positions the base portion in the vehicle front-rear direction with respect to the vehicle body, and the base portion in the vehicle lateral width direction with respect to the vehicle body. It is configured to perform positioning.

  According to this configuration, when the support truck is moved toward the vehicle body and the positioning portion engages with the vehicle body, the grass collection device that is off the vehicle body is located at a position where the support truck is located when the positioning portion is engaged. Since it can be set as a place to place the support cart on the vehicle, when removing the grass collection device from the vehicle body, simply move the support truck toward the vehicle body and engage the positioning part with the vehicle body The grass collecting device, which has been removed from the vehicle body, can be properly placed on the support cart after being placed in a place, and the grass collecting device can be removed quickly.

  In the present invention, in the riding-type mower, the support mechanism is supported by a rear portion of the vehicle body so as to be vertically swingable, and is configured by a link mechanism for vertically moving the grass collection container with respect to the vehicle body. One end side is detachably connected to the rear part of the vehicle body, the other end side is connected to the link mechanism, and a lifting cylinder for rocking the link mechanism is provided in the grass collecting device. It is preferable that the base portion is provided with a cylinder support portion that supports the lift cylinder that is in the state of being separated from the lift cylinder in a set extension/contraction length state and in a set connection posture with respect to the link mechanism.

  With this configuration, the attitude of the link mechanism against the grass container when the lifting cylinder is supported by the cylinder support portion is set so that the link mechanism is easily connected to the vehicle body when the link mechanism is connected to the vehicle body. Since it can be set as the posture of the link mechanism to connect to the grass collection container, which is equivalent to the position of the link mechanism in the vehicle, when the grass collection device is attached to the vehicle body, it is not necessary to adjust the position of the link mechanism with respect to the vehicle body, or it can be done quickly. Therefore, the link mechanism can be quickly connected to the vehicle body.

  In the present invention, it is preferable that the plan view shape of the base portion is a frame shape.

  According to this configuration, since the inside of the base is hollow and the base is light, the support carriage can be easily moved and operated.

The riding mower according to the present invention is
A grass cutting device provided on the vehicle body, a support mechanism detachably supported on the rear portion of the vehicle body, and a grass collection container supported by the support mechanism and supplied with and storing the mowing grass obtained by the grass cutting device. A grass collecting device having, and when the support mechanism is attached to and detached from the vehicle body, the grass collecting device is mounted, and a supporting carriage for mounting and supporting the mounted grass collecting device, A positioning portion that is engaged with the vehicle body so as to be disengageable from the rear of the vehicle body, and the positioning portion is engaged with the vehicle body when the vehicle body of the vehicle body is supported. To the vehicle body in the front-rear direction, and to position the supporting carriage in the vehicle body lateral direction with respect to the vehicle body.

  According to this configuration, by engaging the positioning portion with the vehicle body, it is possible to set a place where the support cart should be placed so that the grass collection apparatus detached from the vehicle body is properly placed on the support cart. When detached, the detached grass collecting device can be placed on the support carriage in a good condition, and the grass collecting device can be quickly removed.

A transport duct 9 for transporting the grass container 11 is provided. The transport duct 9 is provided below the vehicle body so as to pass through a portion between the left rear wheel 2 and the right rear wheel 2 in the front-rear direction.

[About the structure of the grass collecting device]
As shown in FIGS. 2 and 3, the grass collection device 10 includes a grass collection container 11 and a link mechanism 12 that constitutes a support mechanism that supports the grass collection container 11 on the vehicle body.

  The link mechanism 12 extends rearward from the support frame 13 provided on the rear portion of the vehicle body so as to be vertically swingable. The extended end of the link mechanism 12 is connected to the grass collection container 11 so as to be relatively swingable. As shown in FIG. 1, the support frame 13 is supported on the rear portions of the left and right vehicle body frames 14 via a connecting member 15. The grass container 11 descends with respect to the vehicle body by the swinging operation of the link mechanism 12 to store the grass from the grass mowing device 8 in a descending storage posture, and raises the grass grass to discharge the stored grass. Ascending and discharging posture, and is raised and lowered.

  Specifically, the link mechanism 12 includes a pair of left and right link mechanism portions 12A. The left link mechanism portion 12A extends rearward from the left column portion 13a of the support frame 13 so as to be vertically swingable. The extended end portion of the left link mechanism portion 12A is swingably connected to a link support portion 11a provided on the left lateral side portion of the grass container 11. The right link mechanism portion 12A extends rearward from the right support portion 13a of the support frame 13 so as to be vertically swingable. The extended end portion of the right link mechanism portion 12A is swingably connected to a link support portion 11a provided on the right lateral side portion of the grass container 11.

The left and right link mechanism portions 12A are configured to be detachably attached and vertically swingably attached to the column portion 13a based on the connecting structure shown in FIGS.
That is, as shown in FIG. 4, a connecting portion 16 is provided on the front portion of the link mechanism portion 12A, which extends from the upper link member 12u and the lower link member 12d of the link mechanism portion 12A. Each of the upper link member 12u and the lower link member 12d and the connecting portion 16 are connected via a fulcrum shaft 17 so as to be relatively swingable. Connection holes 18 are formed at two positions above and below the connection portion 16. Two upper and lower support holes 19 corresponding to the two connecting holes 18 are formed in the column portion 13a. A detachable connecting shaft 20 (see FIG. 2) is attached to the upper connecting hole 18 and the upper supporting hole 19, and a detachable connecting shaft to the lower connecting hole 18 and the lower supporting hole 19. When 20 is attached, the link mechanism portion 12A is detachably and vertically swingably coupled to the column portion 13a.
