[Embodiment] 1 is a riding type rice transplanter having the following structure. A boarding floor 5 is stretched above a vehicle body 4 having a pair of left and right driving front wheels 2 and 2 for steering and a pair of left and right driving rear wheels 3 and 3, and a control frame 6 is erected on the front left and right central portions. The steering handle 7 is provided, the prime mover 8 is mounted on the rear side of the vehicle body 4, the floor 5 is inflated upward to cover the same, and the pilot seat 10 is placed on the cover bulging portion 9. The configuration is provided.

Reference numeral 11 indicates a front mission case, and 12 indicates a rear mission case. Reference numeral 13 is a lifting link mechanism. In this, the column 14 is erected on the rear end side of the vehicle body 4, the upper and lower link rods 15a and 15b are pivotally connected to the column side, and the vertical link frame 15c is pivotally connected to the rear end side. A rolling hitch 16 for connecting a working machine is integrally provided to the link frame 15c. Then, the rice planting device 17 is mounted on the rolling hitch 16 so as to be able to roll left and right. Reference numeral 18 denotes a transmission case of the rice transplanter 17, which also serves as a machine frame. Reference numeral 19 denotes a seedling placing table, which is supported on the portion of the case 18 via supports 20 and 21 so as to be able to laterally reciprocate laterally, and a moving rod 22 interlocked with a lateral reciprocating lateral movement mechanism in the case 18. The seedling placing table 13 is connected to. Then, a seedling receiving stopper body 23 provided with a seedling dividing port at the lower end side of the seedling placing table 19 is fixedly attached to the case 18 side, and is integrally formed with the transmission case that branches backward and extends. The seedling planting tool 25 of the planting device 24 provided on the rear end side of the planting section transmission case 28 is configured to separate and plant the seedlings from the seedling dividing opening. 27a is a center float, 27b,
Reference numeral 27b denotes side floats disposed on the left and right outer sides, and in each case, a rear part is pivotally attached and a front side is vertically attached to the case side by a link mechanism or the like.

The switching valve 30 of the hydraulic device 29 for actuating the lifting link mechanism 13 is interposed between the tip side of the center float 27a and the projecting rod fixed to the case 20 to allow the flow. When the toe 27a is pushed upward by a certain amount or more and approaches the case 18 side, the rice planting device 17 is raised, and conversely, when it is too close, the planting device 17 is lowered. .

In the riding-type rice transplanter thus constructed, the operator's awning device 31 of the present invention is constructed as follows. That is, the stays 32 and 32 extending in the lateral direction are projected from the left and right sides of the front end of the vehicle body 4, and the sunshade support frames 33, 32 are extended from the both ends toward the rear upper side.
33 is made to project, and these both are mutually set to the horizontal frame 34.
Connect with. U-shaped frames 36 for holding the sunshade 35 are provided on the left and right sides of the sunshade frame 33, and the sunshade 35 is attached to the lateral frame 34 and the U-shaped frame 36. It is attached.

The rear edge of the sunshade 35 is behind the cover bulge 9 covering the prime mover 8 of the boarding floor 5 and behind the left and right rear parts covering the rear wheel 3 at the same height. The upper floor portion 5a is arranged on the upper front side with respect to the rear end. Then, by allowing the operator to stand on the floor portion 5a protruding rearward from the rear end of the sunshade 35 in plan view, seedlings can be supplied to the seedling placement table 19 of the rear rice planting device 17. Is configured.

Reference numeral 37 denotes a spare seedling mounting table, which is mounted on a support column 38 having bases fixed to the left and right sides of the front mission case 11 and having an L-shaped front view in three stages. Explaining the operation of the above example, the rear end of the sunshade 35 covering the upper part of the cockpit 10 has a step floor-5 stretched on the vehicle body.
When the operator stands on the rear floor portion 5a on the front side of the rear end, the upper sunshade 35 does not get in the way and is in an uncomfortable position to the seedling placement table 19 of the rear rice planting device 17. It is possible to eliminate the unforeseen situation of having to replenish seedlings. In addition, as shown in FIG. 2, the upper portions on the left and right end sides of the step floor-5 are protruded from the sunshade 35 so that the floor-5 and the floor-5 are kept in a standing posture without bending the back of the preliminary seedling placing table 37. It is extremely convenient to walk on 5a so that seedlings can be supplied.

Further, according to this structure, the sunshade 35 can be stretched low above the cockpit 10. Therefore, the stretched area can be reduced and the sunshade function can be fully exerted. Furthermore , the sunshade 35 is not of a type in which the rear side rotates up and down with the front side as a rotation fulcrum (a), and this is rotated by an electric cylinder device 39. The forward / reverse rotation motor 40 for this cylinder is pushed to turn on the switch SW1 by pushing the pedal 41 provided on the upper surface of the floor-5.
If the sunshade 35 is configured to operate up and down by turning the motor 40 forward, stop, and reverse so that the sunshade 35 is up and down so that the sunshade 35 does not get in the way when the operator stands up. It is convenient. When the switch SW1 for up and down operation is arranged so as to interlock with the forward rotation side of the motor when the operator's seat 10 is upright, and the reverse rotation side of the motor when the user sits down, the operator reserves. This is even more convenient because the awning 35 automatically rotates upward due to the operation of standing up and leaving the cockpit 10 when replenishing seedlings.

FIG. 4 is a modified embodiment of FIG. 3, in which the support shaft 42 of the sunshade 35 is vertically movable and the electric cylinder device 43 can be vertically operated. Then, this cylinder-actuating motor 44 is "turned on" of the switch SW2 provided in the lower portion of the control seat 10.
As in the above-described embodiment, the "off" is configured to be forward and reverse .

[0014]

According to the invention described in claim 1, although the sunshade 35 is provided at a relatively low position above the pilot seat 10, the sunshade function can be performed by a small sunshade body. A frame 33 that can stand on both left and right sides of the step floor-5 without being obstructed by the sunshade 35 and extends upward from the traveling vehicle body that supports the sunshade 35 is provided in front of the rear end of the preliminary seedling placing table 37. Since they are arranged, the preliminary seedling placing table 37 in the front part to the seedling planting device 17 in the rear part are arranged.
