The invention provides a hole digging device. The hole digging device comprises a dredging container and a mud retreating device. The mud retreating device comprises a rotating seat and a rotating shaft which are rotationally connected; the mud retreating device further comprises an elastic piece, a gear, a first limiting assembly and a second limiting assembly which are sequentially arranged in the rotating base in an abutting mode in the axial direction of the rotating shaft. The gear and the second limiting assembly coaxially rotate with the rotating shaft, the first limiting assembly can rotate relative to the rotating shaft, and the second limiting assembly limits the first limiting assembly in the axial direction of the rotating shaft; the first limiting assembly and the gear can move in the axial direction. When the second limiting assembly rotates to the second matching position in the first rotating direction, the second limiting assembly relieves axial limitation on the first limiting assembly, and the gear can be pushed to move to the meshing position in the axial direction to be meshed with the toothed bar under the acting force of the elastic piece. When the hole digger returns mud, the gear can be driven to move from the separation position to the meshing position only by swinging the swing rod upwards, the gear drives the rack rod to move downwards, operation is easy, and the hole digging efficiency and the mud returning efficiency are high.
本发明提供一种挖洞器包括挖泥容器和退泥装置；退泥装置包括转动座和转轴，转轴与转动座转动连接；退泥装置还包括沿转轴的轴向在转动座内依次抵接设置的弹性件、齿轮、第一限位组件和第二限位组件；齿轮和第二限位组件与转轴同轴转动，第一限位组件相对于转轴可转动，第二限位组件从转轴的轴向限制第一限位组件；第一限位组件和齿轮均可沿轴向移动；当第二限位组件沿第一转动方向转动至第二配合位置，第二限位组件解除对第一限位组件的轴向限制，弹性件的作用力下可推动齿轮沿轴向移动至齿合位置与齿杆齿合。本发明的挖洞器退泥时，只需向上摆动摆杆即可带动齿轮由分离位置移动到齿合位置，齿轮带动齿杆下移，操作简单，挖洞效率和退泥效率较高。
