Distribution is embedded in the outer sidetracking tooth of the lateral surface of variable diameter drill piece 15.
Centrifugal diameter changing drilling tool action implementation process of planting seedlings is described below in the regional rock of stony desert of the present invention.
1. plant seedlings centrifugal diameter changing drilling tool variable diameter drill piece unblock and locking in the rock of stony desert area
Drill bit 4 is static to be turned to its right side operating position by locking handle 10 in Fig. 2 when not turning and is locked by handle latch hook 14,
Mutual extruding occurs for the wedge between this process active push-plate 7 and passive push-plate 8, and passive push-plate 8 is pushed to the work of its highest
Position.Passive push-plate 8 drives lock plate 11 to move it to highest operating position by connecting pin 9, and lock plate 11 overcomes spring
13 compression stress promotes lock pin 12 to move to its highest operating position.The end portion of lock pin 12 is moved into upwards in Fig. 3
The rotation of the inside of drill bit 4 and releasing to variable diameter drill piece 15 hinders, and now variable diameter drill piece 15 is released state.
When variable diameter drill piece 15 is released state, variable diameter drill piece 15 is rotated into income drill bit 4 inside lock position, with reference to figure
Shown in 4.Locking handle 10 in Fig. 2 is turned into its left side operating position and to be locked by handle latch hook 14, active push-plate 7 and passive
Wedge extruding thrust between push-plate 8 is released, and fixed disk 6 pushes down on lock pin 12, locking by the compression stress of spring 13
Disk 11, connecting pin 9, passive push-plate 8 move downwardly to respective minimum operating position.The end portion of lock pin 12 can be stretched downwards
Go out drill bit 4 and hinder variable diameter drill piece 15 to be turned out, as shown in figure 4, variable diameter drill piece 15 is in lockup state.
Planted seedlings 2. the centrifugal diameter changing drilling tool that planted seedlings in the rock of stony desert area is drilled in embedded major diameter hole and rock
In Fig. 5（a）It is shown when centrifugation bores piece 15 and is in lockup state, tooth is bored in the bottom surface of drill bit 4 can under the driving of motor 2
In the downward drilling small diameter bore of rock interior, such as Fig. 5（c）It is shown.After drill bit 4 is bored into up to desired depth, stop drill bit 4
Turn static and keep depth constant, locking handle 10 is turned into its right side operating position and locked by handle latch hook 14, makes change
Bore piece 15 and be in released state in footpath.
Variable diameter drill piece 15 starts motor 2 after unlocking makes drill bit 4 rotate again, and rotation direction is as shown in figure 4, variable diameter drill
The weightening block M of piece 15 produces centrifugal intertia force FM, FMVariable diameter drill piece 15 can be driven around its pin joint A with drill bit 4 to outside drill bit 4
Side expanded position is rotated.Variable diameter drill piece 15 is turning to any expanded angle φ around A pointsiWhen, corresponding PiOuter sidetracking tooth at position
With the axes O of drill bit 4 apart from riEnsure：ri>ri+1And ri>ri-1.I.e. variable diameter drill piece 15 is in expanded angle φiWhen corresponding outer sidetracking
