2. Description of the Related Art Generally, in this kind of riding agricultural machine, in consideration of a worker on the traveling machine body performing replenishment work such as seedling replenishment work with respect to a working machine connected to the rear part of the traveling machine body, There is a rear step in the position near the work machine that allows the replenishment worker to put his / her foot on it, but in order to perform efficient replenishment work, the work position should be as close as possible to the work machine. Since it is necessary to stabilize the power supply, it is desirable that the replenishment worker stand on the rear step with both feet and work in a posture in which both feet are moved back and forth.

[0003]

Therefore, it is proposed to extend the front and rear width of the rear step so that the replenishment worker can take the working posture, but in this case, it is possible to increase the cost. In addition, there was a problem that the rear part of the fuselage became large and hindered the appearance.

SUMMARY OF THE INVENTION The present invention has been made in view of the above circumstances in order to solve these problems, and provides a working machine connected to a rear portion of a traveling machine body. In a riding agricultural machine in which a worker on a traveling machine body performs a replenishment work, in forming a rear step on which both feet of the replenishment worker rest on a rear portion of the traveling machine body, foot projections are provided at front and rear positions of the rear step, respectively. It is characterized by being formed. In other words, if each foot that is shifted forward and backward steps on the footrest projection, it is possible to maintain a stable working posture even with a rear step with a narrow front and rear width, and as a result, the front and rear width of the rear step can be reduced. It is not possible to reduce the cost as compared with the case of expansion, and it is also possible to eliminate the inconvenience that the rear part of the machine body becomes large and obstructs the appearance. Further, the front and rear footrest projections are characterized in that at least one of the footrests is formed at a position where the replenishment operator on the rear step shifts his / her feet forward and backward. In other words, if you move your foot back and forth on the rear step, at least one foot will hang on the footrest projection, so it is possible to perform replenishment work with both feet not on the footrest projection. As a result, it is not possible to stabilize the posture of the replenishment operator, and the inconvenience that the replenishment operator slips his legs can be prevented as much as possible.

BEST MODE FOR CARRYING OUT THE INVENTION Next, one of the embodiments of the present invention will be described with reference to the drawings. In the drawings, 1 is a traveling machine body of a passenger rice transplanter, and the traveling machine body 1 is a traveling power,
An engine (not shown) that generates working power and hydraulic pump driving force, a transmission case (not shown) that shifts the power generated by the engine, and a front axle that transmits the traveling power output from the transmission case to the front wheels 2. It is composed of a case (not shown), a rear axle case 4 for transmitting traveling power output from the transmission case to the rear wheels 3, and the like.
A planting work machine 6 is connected via a lifting link mechanism 5.

The planted work machine 6 is provided in a drive case 7 for inputting work power supplied from the traveling machine body 1, a plurality of planter cases 8 projecting rearward from the drive case 7, and each planter case 8. It is composed of a planting claw 9, a seedling mount 10 provided above the drive case 8 so as to be slidable left and right, and a plurality of floats 11 provided below the drive case 8 so as to be vertically swingable. Then, at the time of work traveling, the seedlings placed on the seedling mounting table 10 are scraped off by the planting claws 9 and planted on the rice field.
Since the vehicle inclines in a front-high / rear-low manner, and its front end (seedling supply section) reaches a position near the rear of the traveling body 1, the traveling body 1
The seedling supply work can be done from the side.

Reference numeral 12 denotes a machine body cover which covers the traveling machine body 1 from above, and a driver seat mounting cover 12a which projects upward is formed at a rear portion of the machine body cover 12. The driver's seat 13 on which the operator is seated is mounted on the upper part of the driver's seat mounting cover 12a, while the space below the driver's seat mounting cover 12a is used as a space for disposing hydraulic equipment and the like. .

Reference numeral 12b is a main step formed on the front side of the driver's seat mounting cover 12a, and the main step 12b is formed in a substantially flat shape over the entire lateral width of the machine body cover 12. Therefore, it is possible to get on and off from the left and right sides of the traveling machine body 1 and easily move on the traveling machine body 1.

Reference numeral 12c is a rear side step formed on both left and right sides of the driver's seat mounting cover 12a. The rear side step 12c connects the left and right end portions of the main step 12b and a rear step 12d, which will be described later, to a front lower rear height. It is formed so as to be connected by a sloped surface. That is, when the feet are placed on the rear step 12d from the main step 12b side to supply seedlings, the rear side step 12c functions as a passage or a step, but the lower surface of the rear side step 12c has a predetermined interval on the rear wheel 3. Since they face each other, they also function as rear wheel fenders.

As mentioned above, the rear step 12d extends rearward from the rear side step 12c.
Since the position is higher than the main step 12b and in the vicinity of the seedling stand 10, by placing one or both feet on the rear step 12d, seedling replenishing work from the traveling machine body 1 is possible, In this embodiment, since the lower surface of the rear step 12d is opposed to the rear wheel 3 with a predetermined space, the rear side step 12c
Together with it, it is designed to function as a rear wheel fender.

Reference numerals 12e and 12f denote the rear step 12d.
The pair of front and rear footrest projections 12e and 12f are formed in the front and rear end portions of the rear step 12d so as to be oriented substantially in the left-right direction. In other words, when the worker stands on the rear step 12d with both feet and performs seedling replenishment work, by shifting both feet forward and backward and stepping on the footrest projections 12e and 12f with the front and rear feet respectively, the provisional toe and heel can be removed. Rear step 12d
It is possible to maintain a stable working posture even if the work gets out of the area. Therefore, the front and rear width of the rear step 12d can be made as narrow as possible, and as a result, the rear step 1
Compared with the case where the front-back width of 2d is expanded, it is not possible to reduce the cost, and it is possible to eliminate the inconvenience that the rear part of the machine body becomes large and hinders the appearance, and moreover, the footrest projection 12e, The strength of the rear step 12d can also be measured by using 12f as a reinforcing rib.

Further, front and rear footrest projections 12e, 12f
Are formed with a space slightly wider than the front-rear length of the foot (shoes). That is, when the replenishment operator on the rear step 12d shifts his / her both feet back and forth, at least one foot hangs on the footrest projections 12e, 12f, so that both feet do not hang on the footrest projections 12e, 12f. It is possible to prevent replenishment work as much as possible, and as a result, it is not possible to stabilize the posture of the replenishment worker and the inconvenience that the replenishment worker slips is also prevented as much as possible. You can do it.

In the construction configured as described above, when the operator standing on the rear step 12d at the rear of the machine body performs the seedling replenishing work for the planting work machine 6 connected to the rear part of the traveling machine body 1, Since the footrest projections 12e and 12f are formed at the front and rear positions of the rear step 12d, respectively, the operator shifts his / her foot back and forth to move the footrest projection 12e.
By stepping on e and 12f, it is possible to maintain a stable working posture even in the rear step 12d having a narrow front-rear width, and as a result, the cost is increased as compared with the case where the front-rear width of the rear step 12d is expanded. It is not permissible to measure down, and it is possible to eliminate the inconvenience that the rear part of the fuselage becomes large and hinders the appearance.

Further, front and rear footrest projections 12e and 12f
Is formed at a position where at least one of the feet rests when the replenishment operator on the rear step 12d shifts the legs back and forth, so that the replenishment work can be performed without the both feet engaging the footrest projections 12e and 12f. Can be prevented as much as possible to contribute to stabilizing the posture of the worker.

The present invention is not limited to the above-described embodiment, and the upper surface of the rear step 12d does not necessarily have to be flat, for example.
As shown in FIGS. 4A and 4B, a U-shaped curved surface and a V
You may form in a character-shaped inclined surface. And in this case,
Since the bottom surface of the shoe that steps on the projections 12e and 12f for footrest can be arranged as close as possible to the upper surface of the rear step 12d,
This can contribute to stabilizing the posture of the worker.
