Description

DETAILED DESCRIPTION OF THE INVENTION Object of the Invention (Industrial field of application) The present invention relates to a rear step for an operator to stand on the rear section,
The present invention relates to a rear step of a work vehicle such as grass cutting provided with a control device operated in a standing posture.

(Prior Art and Problems to be Solved) Conventionally, the rear step of the work vehicle of this type is formed in a horizontal plate shape and fixed to the vehicle body. Therefore, when performing work on an inclined surface that is inclined in the front-rear direction or the left-right direction, the rear step may be inclined and the foot may be stepped off. For this reason, conventionally, as shown in FIGS. 9 to 11, there is a rear step which is swingably provided in the front-rear direction and the left-right direction. When working on an inclined surface, the rear step should be in a horizontal posture. What was fixed was being done. That is,
An engine 5 is mounted on a vehicle body 3 equipped with the traveling device 1, and a grass cutting device 7 driven by the engine 5 is mounted on the front portion of the vehicle body 3 so as to be able to move up and down. A rear step 9 is provided on the rear portion of the vehicle body 3 so as to be swingable in the front-rear direction and the left-right direction, and can be fixed at an appropriate position. That is, the swing body 13 pivotally attached to the support shaft 11 horizontally fixed to the vehicle body 3 in the front-rear direction so as to be swingable in the left-right direction can be fixed to an appropriate swing position by a nut 15 screwed to the support shaft 11. It is provided. A rear step 9 is horizontally fixed to an arm 19 pivotally attached to a bolt 17 that horizontally penetrates the lower portion of the rocking body 13 in the left-right direction. The rear step 9 is provided so as to be freely fixed in a swinging position by a nut 23 screwed to the bolt 17. On the rear upper surface of the vehicle body 3, there is provided a steering wheel frame 25, a steering lever 27 and other steering devices for a pilot standing on the rear step 9 to grasp.

For work, in case of sloping ground in the left-right direction,
As shown in the figure, the nut 15 is loosened to fix the oscillating body 13 vertically, and in the case of sloping ground in the front-back direction, the nut 23 is loosened and the rear step 9 is fixed horizontally as shown in FIG. By doing so, the rear step 9 can be made horizontal on any inclined surface, and the operator can stably stand on the rear step 9. However, depending on the inclined surface, the work is digitized and the nut 15 , 23, it is necessary to adjust the rear step 9 to a horizontal position, and when changing the direction on the slope, this adjustment is dangerous and troublesome, which is an obstacle to the work.

[Structure of Invention]

(Means and Actions for Solving the Problem) According to the present invention, a rear step is fixed to a vehicle body, and the rear step is formed in a shape that inclines upward toward both sides. When traveling on a slope, the operator places his / her foot on a horizontal portion on the lower side of the inclination of the rear step, so that the operator can stably stand up.

Embodiment An embodiment of the present invention will be described below in detail with reference to the drawings.

1 to 5, a vehicle body 31 equipped with a traveling device 29
An engine 33 is mounted on the vehicle body, and a mowing device 35 driven by the engine 33 is mounted on the front portion of the vehicle body 31 so as to be vertically movable. A rear step 37 is fixed to the rear part of the vehicle body 31, and a frame 39, a steering lever 41 and other control devices are provided on the upper surface of the rear part as a handle for a driver standing on the rear step 37 to grasp. . In the rear step 37, a step plate 45 is fixed on a step frame 43 fixed to the vehicle body 31. The step plate 45 is formed in a shape that is inclined upward toward both sides, and non-slip protrusions 47 are fixed to the upper edges of both ends. Further, the front and rear edges are provided with protrusions 49 protruding upward.

In working, the operator stands on the rear step 37, grasps the handle frame 39 with one hand, operates the steering lever 41 etc. with the other hand, and uses the traveling device 29 which steers by driving the engine 33. It moves forward and performs a mowing operation by the mowing device 35 at the front. When performing work on an inclined surface, as shown in FIG. 1 when tilting in the front-rear direction and as shown in FIG. On the ground 49, put your foot on the central plane as shown in (b) on the level ground, and in the case of descending inclination, put your toes on the protrusion 49 at the front edge of the rear step as shown in (c) to measure stability. Is.

On the left and right slopes, when the slope is descending to the left as shown in FIG. 2, the operator places his foot on the left horizontal part of the rear step 37 as shown in FIG. There is no need to worry about slipping because your work is done by placing your foot on the horizontal part of the right side and on the right down slope as shown in FIG.

6 to 8 show another embodiment of the rear step 37, in which the outer periphery is formed of a metallic pipe 51 and a metallic step plate 45 is fixed thereon, The step plate 45 is bent and fixed to the upper surface of the metal pipe 53 provided at the rear edge so as to project upward to form the protrusion 47.

EFFECTS OF THE INVENTION According to the present invention, it is not necessary to adjust the horizontality of the rear step, and by moving the position of the foot left and right on the inclined surface in the left and right direction, it is possible to prevent the foot from slipping and to perform the work. It can be done safely and easily.
