DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS A power vehicle as an agricultural work machine shown in FIGS. 1 to 7 is an embodiment of the present invention, and is used by attaching a work machine for rice planting to a link device attached to the rear of the machine body. This powered vehicle (agricultural work machine) 1 has a pair of left and right front wheels 2 and 2 and rear wheels 3 and 3, and a transmission case 6 and an engine 7 are provided on a main frame 5 in front and rear. A steering post 9 projects upward from the front of the steering wheel 6, and a steering handle 11 is attached to the upper end of a steering shaft 10 that projects upward from the steering post. A cockpit 13 is provided on an engine cover 12 that covers an upper portion of the engine 7.

On the main frame 5, step supporting frames 15, 16, 16, 17, 17, and 18 are horizontally provided in parallel, and a main step 20 having an upper surface serving as a control floor is mounted on the step supporting frames. Further, elevating steps 21 and 21 are attached to the outer ends of the step supporting frames 17 and 17. With a member that covers the fuselage
A certain main step 20 is divided into two parts on the left and right along a center line 22 of the fuselage. . Locking portions 23A, 2
3B have basically the same structure, and the rear locking portion 2
FIG. 4 shows 3B. That is, the lock plate 27 integrally formed with the engaging portion 26 that engages with the lock pin 25 of the step support frame 18 is fitted in the opening 24 formed in the step member 20L (20R). The lock plate 27 is rotatably attached to a support shaft 29 provided horizontally in the opening 24, and is urged in a predetermined direction by a spring 30. The support shaft 29 is provided integrally with the step member 20L (20R). When the engaging portion 26 is engaged with the lock pin 25, the lock plate 27 is horizontal,
The upper surface is substantially flush with the upper surface of the step member. In this state, when the end of the lock plate 27 opposite to the side on which the engaging portion 26 is formed is pressed from above, the lock plate 27 rotates as shown by a dashed line in FIG. Is disengaged from the lock pin 25, and the step member 20L can be removed outward (to the left). As the unlocking method, for example, as shown by the two-dot chain line in FIG.
May be pushed inward of the aircraft, that is, downward . When the position of the support shaft 29 is set closer to the engagement portion 26, the force for pushing the lock plate 27 against the force of the spring 30 can be small. The step member 20
When mounting the L and 20R, the concave portion 31 formed at the inner end of the step member is fitted to the positioning pin 32 of the step support frame for positioning.

A hood 35 is provided at the front of the body to cover the front of the steering post 9.
This bonnet 35 is the notch 2 of the main step 20.
It is attached to the step support frame 15 in a state where it is fitted to the step support frame 0b. That is, a mounting plate 36 is provided at the front of the bottom surface of the bonnet 35, and concave portions 37, 37 that open rearward are formed at appropriate positions on the mounting plate. Engaging engagement pins 38, 38 project upward. Further, a ridge 39 is formed at the front edge of the upper surface of the step members 20L and 20R. Installation of bonnet 35 is step member 2
This is performed before mounting 0L and 20R. The mounting plate 36 is moved rearward along the upper surface of the step support frame 15, and the engaging pins 38, 38 are engaged with the recesses 37, 37.
5 is attached. Thereafter, the step member 20L,
By attaching 20R, the ridge 3 of the step member
9 contacts the front lower end of the hood 35 so that the hood 35 does not shift forward. As described above, since the hood 35 is provided so as to be easily detachable, replacement of the battery 40 provided at the front portion of the body and other maintenance are easy.

The foot accelerator is provided at the right foot of the operator, and an opening 41 for mounting the foot accelerator is formed at an appropriate position of the step member 20R, and the foot accelerator pedal is covered with the opening. 42 are attached. FIG. 7 is a diagram showing the structure of the accelerator operation unit. Reference numeral 44 denotes an accelerator arm rotatably attached to a bracket 45, and a roller 46 provided at a tip end protruding above the main step 20 from the opening 41.
Is in contact with the lower surface of the foot accelerator pedal 42. The operation of the accelerator arm 44 is transmitted to a wire mounting plate 49 via a spring 48, and an accelerator wire 50 connected to a throttle valve (not shown) of the engine 7 is pulled. A high / low speed switching wire 52 connected to a hand accelerator lever 51 is also attached to the wire mounting plate 49.
When the pedal is on the low speed side, the foot accelerator pedal 4
2 operates the throttle valve, but when the handle accelerator lever 51 is located on the high speed side,
The wire mounting plate 49 is fixed in a state shown by a two-dot chain line in the same figure, so that the engine output is maintained substantially constant in a high output state. As described above, since the foot accelerator pedal 42 is provided on the step member 20R and is independent of other accelerator operation members, the step member 20R can be easily attached and detached.

FIG. 8 shows a main part of a different embodiment, in which a seedling frame 56 is erected between a front axle case 55 and a step support arm 18, and a tubular seedling frame is mounted at an intermediate portion of the seedling frame. The tool 57 is fixed. If necessary, as shown in FIG.
8 is attached. Thus, the seedling frame frames 56, 56
Is provided, the step supporting arms 18 are not cantilevered, and the strength of the frame structure is improved.

[0011]

As described above, according to the present invention,
Agricultural work equipment engages the member that covers the
It can be released by operating the operation section from outside the machine
This makes it easy to attach and remove the
The work such as inspection can be performed easily. Moreover, the operation unit is
Move the unit so that it is pushed inward, and
Operated as before because of the configuration that disengages the side
There is no need to form a finger space for operating the
Therefore, mud accumulation near the operation unit and operation by it
Poor operation of parts is less likely to occur.
