Description

[Detailed Description of the Invention] Technical Field of the Invention This invention relates to a shift position indicating device for a mobile agricultural machine that performs work by turning the handle rod in the front and rear directions depending on the work conditions and type of work.

Technical background of the invention and its problems Conventionally, some mobile agricultural machines perform work by turning the handle rod back and forth depending on the working conditions and type of work. The position of the operator changes by turning the handle rod, and the operator's position changes when the handle rod is turned forward and when the handle rod is turned backwards. For the worker, the direction of travel is a forward state or a backward state. For this reason, two sets of shift position indicating marks indicating the shift position of the shift lever are provided, one for when the handlebar is turned forward and one for when the handlebar is turned backward. However, these two sets of shift position indicating marks are arranged close to each other and are planar. For this reason, when the handlebar is turned in any direction (forward or backward), the other set of shift position indication marks, which are unnecessary in the handlebar turn, can be seen, making it difficult for inexperienced workers or sudden workers to do so. There is a risk of misreading the gear shift position indicator and misoperating the gear shift lever, resulting in a serious accident.

Purpose of the invention This invention was made in view of the above points, and the object is to obtain a gear shift position indicating device for a mobile agricultural machine that can prevent erroneous operation of the gear shift lever due to misreading of the gear shift position indicating mark.

Summary of the invention This invention is a mobile agricultural machine in which the handle rod can be turned in the front-rear direction. A shift position indicator mark is provided on the slope facing the rear to indicate the shift position of the gear shift lever when the handlebar is turned backwards, and a gearshift position indicator mark is provided on the slope facing forward to indicate the shift position of the gearshift lever when the handlebar is turned backwards. By providing a mark indicating the shift position of the shift lever when the gear lever is turned, only the shift position indicating mark that matches the direction of the handlebar can be seen even when the handlebar is turned in either direction, forward or backward. This structure is designed to prevent erroneous operation of the gear shift lever due to misreading of the gear shift position indication mark.

Embodiment of the invention An embodiment of the invention will be described based on the drawings. The handle rod 2 of the mobile agricultural machine 1 is provided so that the handle can be turned freely in the front and back direction.
A gear change lever 3 arranged in parallel with the gear lever 3 is also provided so as to be freely turnable in the front-rear direction.

The mobile agricultural machine 1 is provided with a change guide 4 adjacent to the speed change lever 3, and the change guide 4 has an H-shaped guide groove 5 formed therein. A guide pin 6 is fixed to the speed change lever 3 and moves integrally with the speed change operation of the speed change lever 3,
The tip of the guide pin 6 is located within the guide groove 5. Further, an arm 7 is attached to the gear shift lever 3.
is fixed, and the tip of the arm 7 is engaged with a groove of a joint 8 connected to a shift gear (not shown).

A substantially triangular prism-shaped panel 11 is fixed to the change guide 4 as a protrusion having two inclined surfaces 9 and 10 that are inclined diagonally upward in the front-rear direction. On the inclined surface 10 facing backward, there is a first
As shown in the drawings and FIG. 2, a shift position indicating mark 12 is provided to indicate the shift position of the shift lever 3 in a normal state in which the handlebar 2 is turned backward. On the inclined surface 9 facing forward, there is a gear shift lever 3 in a state where the handlebar 2 is turned forward by 180 degrees from the state shown in FIGS. 1 and 2, and the gear shift lever 3 is turned forward by 180 degrees. A shift position indicating mark 13 is provided to indicate the shift position.

In such a configuration, when the handle bar 2 is in the state shown in FIGS.
Only the shift position indicating mark 12 provided on the other inclined surface 9 is visible, and the shift position indicating mark 13 provided on the other inclined surface 9 is in a blind spot and cannot be seen. Therefore, there is no possibility of misreading the shift position indication mark 13 when performing a shift operation, and accidents caused by erroneous operation of the shift lever 3 can be prevented.

Next, when the handlebar 2 is turned forward and the gearshift lever 3 is also turned forward, the gearshift position indication mark 12 on the inclined surface 10 becomes a blind spot for the operator who has moved forward of the mobile agricultural machine 1. The gear shift position indication mark 13 on the inclined surface 9 becomes visible. Therefore, there is no possibility of misreading the shift position indication mark 12 when performing a shift operation, and accidents caused by erroneous operation of the shift lever 3 can be prevented.

Regarding the turn of the gear shift lever 3 in the longitudinal direction, the operation part 14 of the gear shift lever 3 is pulled upward by a predetermined distance from the state shown in FIG. 3, and the engagement between the operation part 14 and the support part 15 is released. Only the operating section 14 is turned, and after the turn is completed, the operating section 14 and the support section 15 are engaged again and integrated.

Effects of the invention With this invention, when the handlebar is turned backwards as described above, only the shift position indication mark required when operating the gearshift lever in that state can be seen. When you turn the handlebar forward, you can only see the gearshift position indication mark that is required when operating the gearshift lever in that state. Even when a gear shift operation is performed in a turned state, it is possible to prevent erroneous operation of the gear shift lever due to misreading the gear shift position indication mark, and this has the effect of improving work safety.
