And press the mulch film, then the drill bit 204 pierces the mulch film downwards and digs holes, and the auxiliary circle 207 can ensure that the mulch film outside the circle will not be pulled or torn.

In order to improve the survival rate of trees, it is hoped that the bottom of the tree hole dug can be large, and the diameter of the mouth is expected to be small in order to make the trees not easy to skew. Specifically, the drill rod 202 includes a fixed rod 2021 and a change rod 2022, The fixed rod 2021 is spirally provided with turbine blades 12 to extract the soil excavated in the pit, the top of the changing rod 2022 is inserted into the inside of the fixed rod 2021 in a controlled manner, and the changing rod 2022 is surrounded by a ring There are a plurality of soil expanding parts 24, and the shape of the soil expanding parts 24 changes with the expansion and contraction of the top of the changing rod 2022 inside the fixed rod 2021. The lower end of the changing rod 2022 is connected with the drill bit 204. When the changing rod 2022 When the top end of the top moves inside the fixed rod 2021, the form of the soil expanding member 24 can change so as to change the hole to be dug.

The specific way to control the movement of the changing rod 2022 is that the inside of the fixed rod 2021 has a cavity, and the inner wall of the cavity is symmetrically provided with an L-shaped groove 2023, and the top of the changing rod 2022 is slidably inserted into the cavity. Inside, the top of the changing rod 2022 is symmetrically provided with a positioning rod 2024 corresponding to the L-shaped groove 2023. When the drill bit 204 is rotated during vertical excavation, the positioning rod 2024 is against the horizontal groove of the L-shaped groove 2023 and cannot be vertically aligned. Movement, when the pothole needs to be expanded, reversely let the drill pipe 202 rotate in the opposite direction, then the positioning rod 2024 moves to the bottom of the vertical direction of the L-shaped groove 2023, and then presses down through the oil cylinder 206, At this time, the changing rod 2022 will extend into the cavity inside the fixing rod 2021 to cause the shape of the soil expanding member 24 to change. That is, the tops of the plurality of soil expanding parts 24 are connected to the outer wall of the lower end of the fixed rod 2021, and the lower ends of the plurality of soil expanding parts 24 are connected to the outer wall of the lower end of the changing rod 2022, and move toward the inside of the fixed rod 2021 along with the changing rod 2022 , a plurality of soil expanding parts 24 expand outwards in form.

When the change rod 2022 protrudes from the fixed rod 2021 the longest, the side walls of the plurality of elastic steel sheets 2401 are closely attached to each other. Form a cylindrical shape as shown in Figure 17. When the changing rod 2022 retracts into the fixed rod 2021, the two ends of the elastic steel sheet 2401 are pressed inward, so that the elastic steel sheet 2401 expands and deforms outwards, thereby forming a middle enlarged The effect is shown in Figure 18, and with the rotation of the drill pipe 202, the soil layer can be excavated to achieve a larger planting space. In addition, in order to make the soil in the hole in the outer straight hole and the bottom big top small, etc., the soil can be well The surface of each elastic steel sheet 2401 is provided with a vortex bar 2402, which can form a channel for lifting soil. The vortex bar 2402 is made of metal material, because the metal does not elastically deform in the direction of the narrow side when it bulges outward. Large, in order to achieve good deformation, a plurality of deformation grooves are opened on the vortex bar 2402, so that it can be bent and bulged outwards, and when bulging, the vortex bar 2402 can be split outwards at the deformation grooves to form The tooth-like shape is more convenient for excavating the soil layer.
