Description

一种小型汽油挖坑机的油门安全控制装置
技术领域
本实用新型涉及工程机械技术领域，尤其涉及小型汽油挖坑机的油门安全控制装置。
背景技术
小型汽油挖坑机又叫做种植机，是指可由一个人操作的，通常用于农作物种植、栽树以及挖坑等作业的小型机械，它能节省人力并提高工作效率，用途非常广泛。
传统小型汽油挖坑机使用时，适合在平坦松软的土地作业，如果挖坑过程中碰到树根或者石块，钻头会因为突然卡住并停止转动，但是此时的汽油机仍旧在高速运转，产生的巨大扭矩导致操纵架和汽油机外壳跟着转动；操作者面对突然增加的扭矩，自然会本能地用力握紧把手，跟着机器一起转动，只有用较大的力气才能控制住机器，但仍有可能擦拭手臂，甚至跟着机器转动而摔倒，作业时存在安全隐患。
现有技术中，有些挖坑机通过在钻头钻杆与汽油机连接处设有缓冲结构，来减缓冲击力，但效果不理想。也有挖坑机通过在汽油机的输出端设置刹车结构，靠摩擦力来减少扭矩的传递，由于汽油机仍然在高速运转，高负荷使得离合器打滑，会影响产品的使用寿命。
实用新型内容
本实用新型针对现有技术中存在的问题，提供一种设计合理、操作安全、简单轻便的小型汽油挖坑机的油门安全控制装置。
一种小型汽油挖坑机的油门安全控制装置，包括操纵架，操纵架相对的两侧分别设有把手，右侧为油门操纵把手，左侧为操纵架平衡把手，操纵架上方固定设有油门控制装置。油门控制装置与操纵架中间位置所安装的汽油机通过油门线相连接，油门控制装置一侧设有触碰杆，油门操纵把手通过油门线与油门控制装置相连接。
当挖坑机工作时，如果旋转的钻头碰到树根或者石块，钻头会突然停止转动，反向的冲击力将带动操纵架按逆时针方向偏转，操作者的身体会碰到触碰杆，触碰杆转动调节油门控制装置，减少汽油机的油量供给，将汽油机的转速降低，扭矩减少，操作者就容易控制挖坑机。
当触碰杆到达极限位置B时，油门线完全松开，汽油机油门处于怠速状态，离合器脱离接触，没有扭矩输出，没有使操纵架偏转的力，操作者很容易重新找回平衡。
当操纵架重新回到原来位置时，触动杆会自动回复到初始位置A，汽油机恢复正常工作。
因为突然卡住并停止转动，通过减少汽油机的油门供给，将汽油机的转速降低，扭矩减少，操作者容易重新找回平衡，避免了因扭矩过大而产生的危险，同时也能保护机械设备本身，延长使用寿命。

图2：本实用新型的立体结构示意图；
图中：1、操纵架；2、油门操纵把手；3、操纵架平衡把手；4、油门控制装置；5、汽油机安装位置；6、油门线；7、触碰杆；A、触碰杆的初始位置；B、触碰杆的极限位置。
具体实施方式
下面结合图1和图2对本实用新型作进一步描述。
一种小型汽油挖坑机的油门安全控制装置，包括操纵架1，操纵架1相对的两侧分别设有把手，右侧为油门操纵把手2，左侧为操纵架平衡把手3，操纵架1上方固定设有油门控制装置4。油门控制装置4与操纵架1中间位置所安装的汽油机通过油门线6相连接，汽油机安装在汽油机安装位置5，在油门控制装置4一侧设有触碰杆7，油门操纵把手2通过油门线6与油门控制装置4相连接。
当挖坑机工作时，如果旋转的钻头碰到树根或者石块，钻头会突然停止转动，反向的冲击力将带动操纵架按逆时针方向偏转。操作者会出于本能，更加用力地紧握油门操纵手把和操纵架平衡把手，完全没有能力松开油门操纵把手，于是双手和手臂跟着操纵架一起转动，而身体还来不及跟着转。这时，操作者的身体会碰到触碰杆，使触碰杆由初始位置A向触碰杆的极限位置B方向发生转动，从而调节油门控制装置，随着触碰杆由A到B转过角度的增加，逐渐松开油门线，减少汽油机的油量供给，将汽油机的转速降低，扭矩减少，操作者就容易控制挖坑机。
当触碰杆到达极限位置B时，油门线完全松开，汽油机油门处于怠速状态，离合器脱离接触，没有扭矩输出，没有使操纵架偏转的力，操作者很容易重新找回平衡。
当操纵架重新回到原来位置时，触动杆会自动回复到初始位置A，汽油机恢复正常工作。
本实用新型设计合理，操作安全，简单轻便，即使在布满砖石的地方钻孔作业，操作者也可很容易重新找回平衡，避免了因扭矩过大而产生的危险，操作无安全隐患，同时也能保护机械设备本身，延长产品使用寿命。
