Description

Technical Field

[0002] Tree planting and afforestation is a production activity of creating new forests or renewing existing ones. It is a basic link in forest cultivation. If the planting area is large and can form a forest and forest environment in the future, it is called afforestation. If the area is very small and cannot form a forest and forest environment in the future, it is called tree planting. The basic measures for afforestation are: selecting suitable trees for suitable land, meticulous site preparation, using good-quality seeds and strong seedlings, proper close planting, tending and protection, tool reform, and possible irrigation and fertilization. Tree planting and afforestation can prevent wind and fix sand.

[0003] When carrying out tree planting and afforestation, it is necessary to first dig a tree planting hole and then plant the sapling in the hole. However, most of the existing hole-digging devices for tree planting and afforestation can only dig one tree planting hole at a time, resulting in relatively low work efficiency; some hole-digging devices for tree planting and afforestation can dig two tree planting holes at a time, but the distance between the two dug holes is fixed and cannot be adjusted according to the needs of tree planting and afforestation, with a small scope of application and inconvenient use.

[0014] A method for using a fixed-distance hole-digging device for afforestation, comprising the following specific steps: S1: Use the push rod and the bottom wheels to move the device to the required position so that the first drill bit is located above the plant pit of the first hole to be dug. S2: Take out the second horizontal screw rod and the second horizontal shaft from the placement groove, insert the two inserting rods into the two inserting slots respectively, and the first magnet and the second magnet attract each other to fix the inserting rods in the inserting slots, thereby fixing the first horizontal screw rod and the second horizontal screw rod together and connecting them by threads, and fixing the first horizontal shaft and the second horizontal shaft together. S3: Rotate the screw rod to move the screw rod on the T-shaped plate. The screw rod drives the first sleeve shaft to move through the Z-shaped moving plate, and the first sleeve shaft drives the driving gear to move until it meshes with the first driven gear. S4: Start the forward and reverse motor to drive the first vertical shaft to rotate. The first vertical shaft drives the first horizontal shaft to rotate through the meshing of the first driving bevel gear and the first driven bevel gear. Since the first horizontal shaft and the first sleeve shaft are connected by splines, the first horizontal shaft drives the first sleeve shaft to rotate. The first sleeve shaft drives the first horizontal screw rod to rotate through the meshing of the driving gear and the first driven gear. The first horizontal screw rod drives the second horizontal screw rod to rotate together, thereby driving the L-shaped moving plate to move rightward on the first horizontal screw rod and the second horizontal screw rod. The L-shaped moving plate drives the second sleeve shaft and the second vertical shaft to move rightward together on the first horizontal shaft and the second horizontal shaft. The second vertical shaft drives the second drill bit to move rightward through the second rotating shaft until the second drill bit moves above the plant pit of the next hole to be dug. S5: Rotate the screw rod to move the screw rod on the T-shaped plate. The screw rod drives the first sleeve shaft to move through the Z-shaped moving plate, and the first sleeve shaft drives the driving gear to move until it meshes with the second driven gear. S6: Start the forward and reverse motor again to drive the first vertical shaft to rotate. Since the first vertical shaft and the first rotating shaft are connected by splines, the first vertical shaft drives the first drill bit to rotate through the first rotating shaft. S7: Similarly, the first vertical shaft drives the first horizontal shaft to rotate, the first horizontal shaft drives the first sleeve shaft and the second sleeve shaft to rotate, the second sleeve shaft drives the second vertical shaft to rotate through the meshing of the second driving bevel gear and the second driven bevel gear. Since the second vertical shaft and the second rotating shaft are connected by splines, the second vertical shaft drives the second drill bit to rotate through the second rotating shaft. S8: The first set of shafts drives the linkage shaft to rotate through the meshing of the driving gear and the second driven gear. The linkage shaft drives the vertical lead screw to rotate through the meshing of the third driving bevel gear and the third driven bevel gear, thereby driving the connecting plate to move downward on the vertical lead screw. The connecting plate drives the first lifting plate to move downward, and the first lifting plate drives the first drill bit to move downward through the first rotating shaft. S9: The first lifting plate drives the second lifting plate to move downward through the Z-shaped plate and the L-shaped rod. The second lifting plate drives the second drill bit to move downward through the second rotating shaft, thereby driving the first drill bit and the second drill bit to rotate and move downward simultaneously to complete the hole digging for two tree planting pits.

[0015] The beneficial effects of the present invention are as follows: It can dig two tree planting pits at one time, improving work efficiency; the distance between the two tree planting pits can be adjusted according to the needs of tree planting and afforestation and then fixed, ensuring that it does not change during the hole digging process, expanding the applicable range of the equipment and making it more convenient to use; the adjustment, lifting, and rotation of the distances between the two drill bits are completed only by one driving device in cooperation with different mechanisms, making the whole equipment more strongly linked and eliminating the need to set up complex programs to cooperate with different driving devices.
