Description of the Related Art Generally, in this kind of riding agricultural machine, it is considered that a worker on the traveling machine performs replenishment work such as seedling supply to a working machine connected to a rear portion of the traveling machine. In the vicinity of the work machine, there is a rear step that allows the replenishment worker to put his feet on. However, in order to perform efficient replenishment work, it is necessary to get as close to the work machine as possible and work posture Therefore, it is desirable that the replenishment worker stands on the rear step with both feet and works in a posture in which both feet are shifted back and forth.

[0003]

However, when the replenishment position on the working machine side is low, such as when supplying seedlings for a riding rice transplanter, the worker standing on the rear step must bend forward. Even when the temporary commander's feet were shifted back and forth, there was a possibility that the work efficiency would be reduced due to the forced posture.

[0004]

SUMMARY OF THE INVENTION The present invention has been made in order to solve these problems in view of the above-mentioned circumstances, and is directed to a working machine connected to a rear portion of a traveling body. In a riding agricultural machine in which a worker on the traveling body performs a replenishing operation, in forming a rear step on which both feet of the replenishing worker rest on the rear part of the traveling body, the rear step has a high front side and a low rear side. A footrest is formed. In other words, the hind legs are high,
Since it is possible to stand on the rear step with the forefoot low, the operator can easily take a forward bent position, and as a result, the efficiency and workability of the replenishment operation can be improved. Further, the rear footrest is located behind the top of the rear wheel. That is,
When the rear step functions as a fender that covers the upper part of the rear wheel, the rear step can be made to follow the outer circumference of the rear wheel, ensuring an appropriate distance from the rear wheel and improving the performance as a fender Can be done.

Next, one embodiment of the present invention will be described with reference to the drawings. In the drawings, reference numeral 1 denotes a traveling body of a riding rice transplanter, and the traveling body 1 has traveling power,
An engine (not shown) for generating working power and hydraulic pump driving force, a transmission case (not shown) for shifting the generated power of the engine, and a front axle for transmitting running power output from the transmission case to front wheels 2 A case (not shown), a rear axle case 4 for transmitting the traveling power output from the transmission case to the rear wheels 3 and the like are provided.
A planting work machine 6 is connected via a lifting link mechanism 5.

The planting work machine 6 is provided in a drive case 7 for inputting work power supplied from the traveling machine body 1 side, a plurality of planter cases 8 projecting rearward from the drive case 7, and each planter case 8. It comprises a planting claw 9, a seedling mounting table 10 slidably provided above and below the drive case 8, and a plurality of floats 11 provided below the drive case 8 so as to be swingable up and down. At the time of work traveling, the seedlings placed on the seedling mounting table 10 are scraped with the planting claws 9 and planted on the rice field.
Since the front end (seedling replenishing section) reaches a position near the rear of the traveling body 1, the traveling body 1 is inclined.
Seeding can be performed from the side.

A body cover 12 covers the upper part of the traveling body 1. A driver seat cover 12 a is formed at the rear of the body cover 12 so as to protrude upward. The driver's seat 13 on which the operator sits 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 denotes a main step formed on the front side of the driver's seat mounting cover 12a. The main step 12b is formed in a substantially flat shape over the entire left and right width of the body cover 12. Therefore, it is possible to get on and off from both left and right sides of the traveling body 1 and to easily move on the traveling body 1.

Reference numeral 12c denotes a rear side step formed on the left and right sides of the driver's seat mounting cover 12a. The rear side step 12c connects the left and right ends of the main step 12b and a rear step 12d, which will be described later, with a low front and rear height. It is formed so that it may be connected by an inclined plane. In other words, when seedling replenishment is performed by placing a foot on the rear step 12d from the side of the main step 12b, 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 distance from the rear wheel 3. Because they face each other, they also function as rear wheel fenders.

The rear step 12d extends rearward from the rear side step 12c as described above.
Since the position is higher than the main step 12b and in the vicinity of the seedling mount 10, placing one foot or both feet on the rear step 12d enables the seedling replenishment work from the traveling machine 1 to be performed. In the present embodiment, since the lower surface of the rear step 12d is opposed to the rear wheel 3 with a predetermined interval, the rear side step 12c
It also functions as a rear wheel fender.

[0012] 12e, 12f is the rear step 12d
Are formed on the front end and the rear end of the rear step 12d so as to extend substantially in the left-right direction. In other words, when the worker stands with both feet on the rear step 12d to perform the seedling replenishment operation, the feet are shifted forward and backward, and the footsteps 12e and 12f are respectively stepped with the front and rear feet. Rear step 12d
It is possible to maintain a stable working posture even if the work is protruded from the vehicle. Therefore, the front and rear width of the rear step 12d can be made as narrow as possible.
The cost can be reduced as compared with the case where the front-rear width of 2d is expanded, and the disadvantage that the rear part of the fuselage becomes large and obstructs the appearance can be solved. 12f can also be used as a reinforcing rib so that the strength of the rear step 12d can be increased.

The footrest (the upper surface of the rear step) of the rear step 12d is generally formed on a horizontal flat surface, but in the present invention, the front side of the footrest is high, and The rear side is formed low. That is, when the worker stands with both feet on the rear step 12d to perform the seedling replenishment operation, the foot shifted rearward is placed on the front foot rest 12g, and the foot shifted forward is placed on the rear foot rest 12h. Then, it is possible to stand on the rear step 12d in a posture where the rear foot is high and the front foot is low. Therefore, when supplying seedlings to the seedling mounting table 10 at the rear of the machine, it becomes possible for the worker to take a forward bent posture without difficulty, and as a result, the efficiency and workability of the seedling supply operation can be improved. It has become.

In this embodiment, the rear step 12
In consideration of the fact that d functions as a rear wheel fender, the rear footrest 12h is formed at a position rearward of the top of the rear wheel 3 so that an appropriate distance is provided between the rear step 12d and the rear wheel 3. The gap is secured so that the performance as a rear wheel fender can be improved.

In the construction as described above, when a worker standing on the rear step 12d at the rear of the machine body performs a seedling replenishing operation on the planting work machine 6 connected to the rear part of the traveling machine body 1, Since the rear step 12d is formed with the footrests 12g and 12h with the front side being high and the rear side being low, the worker who supplies seedlings stands on the rear step 12d with the hind legs high and the front legs low, and It is possible to take a leaning posture, and as a result, it is possible to improve the efficiency of the replenishment work and improve the workability.

Further, since the rear foot rest 12h is located behind the top of the rear wheel 3, the rear step 12d functions as a fender for covering the rear wheel 3 from above.
The rear step 12d can be arranged along the outer periphery of the rear wheel 3, and as a result, an appropriate interval can be secured between the rear step 3d and the rear wheel 3 to improve the performance as a fender.

The present invention is, of course, not limited to the above-described embodiment. For example, as shown in FIG. 4, the rear footrest 12h may be arranged rearward and lower than the above-described embodiment. It may be formed on the side, and in this case, it is not permissible for the operator to easily take a forward bent position, and the performance as a rear wheel fender can be enhanced.
