Specific embodiment
With reference to the accompanying drawing, the specific embodiment of the present invention is described in detail, it is to be understood that of the invention
Protection scope be not limited by the specific implementation.
Embodiment one:
As shown in Figure 1, a kind of potato field experiment Sign Board 32 provided in an embodiment of the present invention, comprising:
Base shaft 00, cylindrical, bottom has tip, facilitates insertion into soil, offers mounting hole 133 thereon, pacifies
Filling hole 133 can be threaded hole, so as to fasten installation；
Embedded device comprising pressing sleeve 20, impact block 21, impact spring 22, limiter 23 and guide spring 24, the pressing sleeve
There are a containing cavities 201 in 20, be provided with guide pad 202 in the containing cavities 201, containing cavities 201 are divided by guide pad 202
Upper and lower part, guide pad 202 are cyclic structure, and the lower end surface of the guide pad 202 offers the first guide surface 2021, first
The cross section of guide surface 2021 is in taper type, and the lower end of the pressing sleeve 20 offers pilot hole, and the pilot hole is penetrated through to described
In containing cavities 201, the pilot hole is matched with the base shaft 00, for providing guiding to base shaft 00, base shaft 00 being kept not send out
Raw deflection, the impact block 21 are located in the containing cavities 201 and are located at the top of the guide pad 202, the impact spring
22 one end are connected in the containing cavities 201, the other end is connected on the impact block 21, and the lower end of the impact block 21 opens up
There is relief hole 211；The limiter 23 includes the resigning bar 233 matched with the relief hole 211, and relief hole 211 is rounded,
Resigning bar 233 is also cylindrical, and resigning bar 233 is inserted into relief hole 211, the lower end of the resigning bar 233 offer with
The second guide surface 232 that first guide surface 2021 matches, the first guide surface 2021 are matched with the second guide surface 232
When, the first guide surface 2021 can force limiter 23 to be ajusted, and be inserted into resigning bar 233 in relief hole 211, the limiter 23
Bottom end offer the deflection plane 231 of arc, described 24 one end of guide spring is connected in the containing cavities 201, the other end connects
It connecing on the limiter 23, guide spring 24 is inclination arrangement, so that in the case where limiter 23 is not by external force, it can
To force limiter 23 to be in tilted layout, i.e., resigning bar 233 is not inserted into relief hole 211；When base shaft 00 withstands limiter 23, limit
Resigning bar 233 on the device 23 of position withstands the lower end of impact block 21, so that impact block 21 is motionless, pressing sleeve 20 is moved down, pressing sleeve 20 and punching
It hits and generates relative movement between block 21, and impact spring 22 compresses at this time, accumulation of energy.During this, guide spring 24 is also generated
Compress energy storage.When the first guide surface 2021 and the second guide surface 232 cooperate, the first guide surface 2021 forces limiter 23 to return
Just, resigning bar 233 is inserted into relief hole 211, and impact block 21 has activity space, downward shock limiter 23, limiter
Power is transferred to base shaft 00 by 23, and impact base shaft 00 protrudes into soil；
Bracket comprising hanging rod 30 and fixed link 31, the fixed link 31 are matched with the mounting hole 133, fixed link
External screw thread can be opened up on 31, be threadedly engaged with mounting hole 133；And
Sign Board 32 is arranged on the hanging rod 30.
In order to make limiter 23 can be better maintained heeling condition under the action of not by the first guide surface 2021, institute
State deflection plane 231 be unsymmetric structure, asymmetric mechanism can make base shaft 00 by base shaft 00 top then, can because of by
Power is uneven and limiter 23 is deflected.
Embodiment two:
Since in the soft field of some soil properties, base shaft 00 is easy because soil property changes or Sign Board 32 after being inserted into
Base shaft 00 is caused to be detached from from soil or skew by wind stress, on the basis of example 1, base shaft 00 of the invention is wrapped
Include drilling rod 10 and upright bar 13；
As shown in Fig. 2 to Figure 12, the drilling rod 10 includes that from top to bottom sequentially connected connecting rod 12, expansion segment and brill are native
Section, external screw thread is offered in the connecting rod 12, the expansion segment has the expansion face 11 from top to bottom expanded outwardly；
As shown in figure 5,13 lower end of upright bar offers expansion slot, offered in the expansion slot and the external screw thread phase
The threaded joints 131 of cooperation offer internal screw thread in threaded joints, are circumferentially evenly arranged on the side wall of the expansion slot
Ground offers extension mouth 134, and to form multiple expanding plates being arranged circumferentially along upright bar 13, the internal screw thread is located at the expansion
Dehisce 134 upper end, the upper end of the internal screw thread offers resigning chamber, and the internal diameter of resigning chamber is greater than the major diameter of internal screw thread, described
Resigning chamber is penetrated through to the expansion slot, and the connecting rod 12 at least has the first working condition and the second working condition, when being in
When the first working condition, the external screw thread is meshed with the internal screw thread, and the expansion slot is separated with the expansion segment；Work as place
When the second working condition, the external screw thread is separated with the internal screw thread, and the external screw thread is intracavitary positioned at the resigning, described
The lower end of expansion slot and the expansion face 11 are inconsistent.
In use, on the offensive buttress drilling rod 10, match the external screw thread of connecting rod 12 with the internal screw thread in upright bar 13, presses
Pressing sleeve 20, so that impact block 21 impacts upright bar 13, upright bar 13 and drilling rod 10 be threadedly engaged, and is fixed, therefore drilling rod 10 at this time
It can protrude into soil, when extending into certain depth, range estimation expansion slot has submerged rotation upright bar in soil after the distance of one end completely
13, so that the internal screw thread of upright bar 13 and the external screw thread of connecting rod 12 is separated, the external thread section in connecting rod 12 is made to protrude into cushion chamber
In 132, expansion slot is resisted against on expansion segment at this time, continues to press pressing sleeve 20, due to 10 bottom of drilling rod at this time soil by
That presses is more closely knit, therefore the opposition by soil is larger, and expanding plate can be to week under the action of expanding face 11 at this time
Side expansion, is inserted into soil, forms the trend expanded around, ultimately forms the horn-like structure gradually tapered up upwards, can be with
It provides and the biggish binding force of soil, the stability of promotion base shaft 00.
When being blown due to Sign Board 32 by wind, external force will receive, and when wind-force is larger, suffered external force is also larger,
It needs to uninstall power, the stability of base shaft 00 could be kept well, therefore the invention also includes adsorption magnet 321, it is described
Adsorption magnet 321 is hinged on the hanging rod 30, and the Sign Board 32 is adsorbed on the adsorption magnet 321.Adsorption magnet 321
The mode of absorption Sign Board 32 facilitates installation, and adsorption magnet 321 is hinged on hanging rod 30 and unloads the strength of wind with can be convenient
Fall, reduces the load of base shaft 00.
Disclosed above is only several specific embodiments of the invention, and still, the embodiment of the present invention is not limited to this, is appointed
What what those skilled in the art can think variation should all fall into protection scope of the present invention.
