Abstract[English]
Provided are a lawn mower and a cutting deck lifting/lowering device. The lawn mower comprises a frame (1), a seat, a cutting deck (3) and a cutting deck lifting/lowering device; the cutting deck lifting/lowering device comprises an operating member (11), a translation mechanism, a linkage mechanism and a gear member (10); the linkage mechanism comprises an elastic member (12) connected to the operating member (11), the elastic member (12) driving the operating member (11) to have a tendency of entering a gear recess (102). By providing the elastic member (12) between the linkage mechanism and the operating member (11), when vibration of the lawn mower causes the operating member (11) to have a tendency of moving toward a disengagement direction, the elastic member (12) pulls the operating member (11) and generates a driving force pointing toward the direction of the gear recess (102), thus avoiding the problem that the cutting deck (3) falls to the lowest point when the operating member is automatically disengaged from the gear recess (102) under abnormal road conditions such as jolts.[French]
L'invention concerne une tondeuse à gazon et un dispositif de levage/abaissement de plateau de coupe. La tondeuse à gazon comprend un cadre (1), un siège, un plateau de coupe (3) et un dispositif de levage/abaissement de plateau de coupe ; le dispositif de levage/abaissement de plateau de coupe comprend un élément d'actionnement (11), un mécanisme de translation, un mécanisme de liaison et un élément engrenage (10) ; le mécanisme de liaison comprend un élément élastique (12) relié à l'élément d'actionnement (11), l'élément élastique (12) entraînant l'élément d'actionnement (11) pour qu’il ait tendance à entrer dans un évidement d'engrenage (102). En fournissant l'élément élastique (12) entre le mécanisme de liaison et l'élément d'actionnement (11), lorsque la vibration de la tondeuse à gazon amène l'élément d'actionnement (11) à avoir tendance à se déplacer vers une direction de désengagement, l'élément élastique (12) tire l'élément d'actionnement (11) et génère une force d'entraînement pointant vers la direction de l'évidement d'engrenage (102), ce qui permet d'éviter le problème selon lequel le plateau de coupe (3) tombe au point le plus bas lorsque l'élément d'actionnement est automatiquement dégagé de l'évidement d'engrenage (102) dans des conditions de route anormales telles que des secousses.[Chinese]
提供一种割草机及割台升降装置。割草机包括车架(1)、座椅、割台(3)和割台升降装置;割台升降装置包括:操纵件(11)、平动机构、联动机构和挡位件(10);联动机构包括连接于操纵件(11)的弹性件(12),弹性件(12)驱动操纵件(11)具有进入挡位槽(102)的趋势。通过在联动机构以及操纵件(11)之间设置弹性件(12),在割草机受震动而使操纵件(11)有向脱挡方向运动趋势时,弹性件(12)拉动操纵件(11)并产生指向挡位槽(102)方向的驱动力,避免操纵件受颠簸等异常路况时自动脱离挡位槽(102)而使割台(3)掉落至最低点的问题。
