The operating condition and principle of the present embodiment are as follows:
When in use, it is necessary first to which the pore-forming process that stake holes is carried out by electronic Luoyang Spade after stake holes pore-forming, passes through
The stake holes base expanding and base expanding device is hung lower stake holes bottom by loop wheel machine.
When being hung to the position of needs under the device, start the positioning mechanism 11 of the device first, stake holes wall is carried out
Push against support, the first positioning as the device.Start the second driving motor 123 later, and then rotates driving gear 51.Actively
When gear 51 rotates, two driven gears 52 and ring gear 53 is driven to rotate.
When driven gear 52 rotates, since driven gear 52 is to be threadedly coupled, while locating rod 6 is received with locating rod 6
It to the limitation of convex block 62 and strip groove 63, can not rotate, therefore locating rod 6 is stretched out down along vertical direction, because of locating rod 6
End be tip 61, therefore can be more easily inserted into stake holes bottom, to complete the secondary positioning of the stake holes base expanding and base expanding device
Work.
Ring gear 53 rotate when, drive external thread sleeve 54 rotate, due to drive block outer ring 41 by with mounting rack 121
The limitation of fixed inner ring 42 can only move to can not rotate along its axial direction, therefore outer ring 41 is in the work being threadedly engaged
It under, moves down, to drive drive rod to overhanging, and then opens the angle that connecting rod 21 reaches needs.
After the completion of preparatory process, the first driving motor 122 can be started, driven and turned by driving gear 31 and fluted disc 32
Ring 24 rotates, and when change 24 rotates, connecting rod 21 is driven to rotate together, and then using the cutting blade 22 on connecting rod 21 to stake holes
Hole wall carry out expanding.Drive rod and connecting rod 21 are due to being hingedly, also to rotate together, due to drive rod and in outer ring
The lantern ring of 41 lateral surfaces rotation connection is hinged, therefore also connecting rod 21 can be followed to be freely rotated.
After base expanding and base expanding, which works, to be completed, it only need to stop the first driving motor 122, then be then turned on the second driving motor 123,
Pack up locating rod 6 with drive block, slinging the stake holes base expanding and base expanding device finally by loop wheel machine can be completed overall work.
By setting locating rod 6, when connecting rod 21 is packed up, extension elongation and connecting rod 21 are consistent, so that can guarantee that locating rod 6 exists
When stretching, the influence for receiving 21 expansion angle of connecting rod is reduced, because drive block and the power source of locating rod 6 are same power
Source, therefore the length that locating rod 6 is stretched out is relevant with the angle that connecting rod 21 is expanded, setting in this way can make even if expansion angle not
Greatly, it also can guarantee that locating rod 6 is extended with certain length, to guarantee the effect of limitation rotation.
One end by setting locating rod 6 far from mounting rack 121 is tip 61, so that being inserted into stake holes bottom in locating rod 6
When, it can effectively reduce and be difficult to the case where being inserted into because the soil of stake holes bottom is excessively real, if locating rod 6 can not
It is inserted into stake holes bottom, but is stretched out always, it is most likely that the locating effect of the device entirety upper half positioning mechanism 11 is influenced,
To shake or deviate.
This specific embodiment is only the explanation to the utility model, is not limitations of the present invention, ability
Field technique personnel can according to need the modification that not creative contribution is made to the present embodiment after reading this specification, but
As long as all by the protection of Patent Law in the scope of the claims of the utility model.
