Embodiment Construction

[0013] The detailed description and technical content of the present invention are described below with the accompanying drawings, but the accompanying drawings are only provided for reference and description, and are not intended to limit the present invention.

[0014] Attached below figure 1 , attached figure 2 The specific implementation of a gear interlock mechanism for a gearbox of the present invention is further described: when the rocker arm I (1) drives the gear lever I (6) to swing to engage gear, the interlock pin (5) Under the action of gear-engaging rocker arm I (1), it slides in the guide groove (9) of guide plate (4), and slides into the lock groove II (8) of gear-engaging rocker arm II (2), causing gear-engaging rocking Arm II (2) cannot swing to engage gear; when gear arm I (1) returns to the neutral position, its lock groove II (8) is aligned with guide groove (9) of guide plate (4), and gear is engaged. The rocker arm II (2) can drive the gear shift leve...

Abstract

The invention relates to a gear interlocking mechanism for an agricultural machinery gearbox. The gear interlocking mechanism comprises a first gear-engaging rocker arm (1), a second gear-engaging rocker arm (2), a gearbox cover (3), a guide plate (4), an interlocking pin (5), a first gear poking rod (6) and a second gear poking rod (7). The gear interlocking mechanism is structurally characterized in that the first gear-engaging rocker arm (1) and the second gear-engaging rocker arm (2) are installed on the gearbox cover (3) respectively through the first gear poking rod (6) and the second gear poking rod (7), and the interlocking pin (5) is assembled on the gearbox cover (3) through the guide plate (4). The interlocking pin is not subject to limitation of the distance of two shifting fork shafts and whether the shifting fork shafts move, and the applied range is expanded. By bi-directional sliding of the interlocking pin in a first locking groove of the first gear-engaging rocker arm and a second locking groove of the second gear-engaging rocker arm, interlocking limiting is performed, and the goal of preventing a gearbox gear mess is achieved.

Description

technical field [0001] The invention relates to a gear interlock mechanism for an agricultural machinery gearbox, belonging to the field of agricultural machinery. Background technique [0002] At present, the gears of agricultural machinery gearboxes in the domestic market usually do not have an interlock mechanism. Due to the different levels of operators or multiple operators, it often leads to the phenomenon of mechanical disorder. Or some machines have an interlocking mechanism. This interlocking mechanism can only be applied to two side-by-side shift fork shafts that are relatively close and can be moved when in gear. The end of the interlock pin is installed in the arc groove of the shift fork shaft. Interlocking is achieved by relying on the movement of the shift fork shaft to drive the interlock pin when the gear is engaged; this mechanism cannot be applied to agricultural machinery gearboxes where the distance between the two shift fork shafts is relatively long or...
