Punched, reuse soil moisture instrument and measure.But, its technological deficiency existed can not ensure soil moisture instrument
Measure probe accurately enter it is pre-perforated in, and be possible to during descending to be damaged by chad.Meanwhile, it is not provided
The technical inspiration of multiple hole synchro measures.
2nd, denomination of invention：A kind of pre-perforated device available for section soil moisture measurement system；Application number：
201610248040.7；Patent applicant：China Water Resources ＆ Hydropower Science Research Institute.The patent application solves perforating device and limit
Positioning relation between the pipe of position, but can not also ensure that the measurement probe subsequently placed accurately enters in predetermined hole, and if
There is chad in descending, will also result in the damage of detection system.Equally, its technology for also not providing multiple hole synchro measures
Enlightenment.

Embodiment
With reference to Fig. 1 to Fig. 6, the present invention will be further described：
As shown in figure 1, a kind of punching and measurement integrated device for soil moisture measurement, including punching probe 1 and measurement are visited
Pin 2, punching probe 1 is hollow-core construction, and measurement probe 2 is placed in punching probe 1.It is two pieces to punch probe 1, corresponding
It is also two pieces to measure probe 2；Two pieces of punching probes 1 work simultaneously, and two pieces of measurement probes 2 also work simultaneously.Punching probe 1 is punched
After finishing, measurement probe 2 is discharged automatically and carries out soil moisture measurement, it is to avoid measurement probe 2 needs independent to enter pre-perforated
In or enter it is pre-perforated when damaged by chad.
Specifically, punching probe 1 includes cone excavation portion 11, mobile link portion 12, is fixedly connected with portion 13 and punching
Motor 14, punching motor 14 output end be connected with being fixedly connected with the one end of portion 13, be fixedly connected the other end of portion 13 and
The one end of mobile link portion 12 is attached by screw thread, and mobile link portion 12 is stretched under being rotated in the portion that is fixedly connected 13.Move
The other end of rotation connection 12 is connected by connection rotating shaft 15 with cone excavation portion 11.Opened by cone excavation portion in cone excavation portion 11
Shutting mechanism 4 will measure probe 2 and be discharged or be withdrawn.
The above-mentioned portion 13 that is fixedly connected does not mean that it is fixed, and refers to its with punching the output of motor 14
End is fixedly connected, and in the presence of punching motor 14, is fixedly connected with portion 13 and is rotated, and by threaded function in mobile link
Portion 12 rotates it, causes it to be changed with being fixedly connected with the threaded connection length of portion 13 in the rotation process of mobile link portion 12,
It is flexible so as to realize.So, mobile link portion 12 is covered with the bar structure of screw thread with an appearance is needed in the portion that is fixedly connected 13,
Another is covered with the tubular structure of screw thread for inside.The length of both screw threads can wanting according to the movable length of mobile link portion 12
Ask and provided.
Operation principle is as follows：When control receiver is by instructing startup punching motor 14, punching motor 14 is just
Turn, driving is fixedly connected with portion 13 and also rotated forward, finally cause the rotation of mobile link portion 12 to stretch out, the cone of the lower end of mobile link portion 12
Excavation portion 11 starts punching by way of rotation in soil.After punching is finished, control receiver is beaten by instructing to start
Hole motor 14 is inverted, and the rotation of mobile link portion 12 is retracted, and cone excavation portion 11 is also lifted.Similarly, if dug in cone
After pick portion 11 is opened, the punching reversion of motor 14 can cause measurement probe 2 in pre-perforated.
As shown in Fig. 2 cone excavation portion switching mechanism 4 includes expansion link 41, fixed riffled tube 42, flexible hollow tube 43
And release measurement probe actuation motor 45, discharge measurement probe actuation motor 45 and be fixed on the inwall of mobile link portion 12, release
The output end for putting measurement probe actuation motor 45 is connected with fixed one end of riffled tube 42, and the fixed other end of riffled tube 42 is with stretching
The one end of contracting bar 41 is attached by screw thread, and expansion link 41 is stretched in the case where fixed riffled tube 42 is rotated；Flexible hollow tube
43 are fixed on the inwall in cone excavation portion 11, and the other end of expansion link 41, which enters directly to push up in flexible hollow tube 43, opens cone excavation
Portion 11 opens cone excavation portion 11 by the indirect top of flexible hollow tube 43.
Fixed riffled tube 42 and expansion link 41 operation principle is with reference to above-mentioned mobile link portion 12 and is fixedly connected with portion 13
Operation principle.The advantage of selection flexible hollow tube 43 is：The top of expansion link 41 is avoided when opening hemicone 111, expansion link 41 with
The contact position of hemicone 111 can change；Stuck or abrasion is avoided to use flexible hollow tube 43；It may insure cone excavation portion
11 open it is smooth.
Cone excavation portion 11 is at least made up of two hemicones 111, and each hemicone 111 is provided with a flexible hollow tube 43,
Each hemicone 111 is connected by a connection rotating shaft 15 with mobile link portion 12.
The unlatching of two hemicones 111 measures probe actuation motor 45 by a release and realized；Concrete structure is：It is flexible
Bar 41 is connected by connecting annulus 44 with a push rod, and measurement probe 2 passes through connection annulus 44；Expansion link 41 and a hemicone
Flexible hollow tube 43 on 111 coordinates, and push rod coordinates with another flexible hollow tube 43 on another hemicone 111.It is above-mentioned to stretch
Contracting bar 41 and push rod share a motor and driven, and can save space-efficient setting, and can also save manufacturing cost, can be with
Ensure that expansion link 41 works asynchronously all the time with push rod, and two hemicones 111 are synchronously opened.
When needing to close cone excavation portion 11, release measurement probe actuation motor 45 is inverted, and each hemicone 111 needs
Restore to the original state, so each be used to help hemicone 111 between hemicone 111 and mobile link portion 12 provided with a back-moving spring 46
Cone structure can be reverted to after being opened.
As shown in figure 3, the surface of mobile link portion 12 is provided with the helical groove 16 for facilitating soil to export.
As shown in figure 4, punching and measurement integrated device of the present invention for soil moisture measurement also include mounting platform 3,
Punching motor 14 is fixed on mounting platform 3, and one end of measurement probe 2 is also mounted on mounting platform 3, mounting platform 3
Top connects an extension rod 5.In addition, also including a position-limiting tube 6, its whole pipe shaft is embedded in soil；The inwall of position-limiting tube 6 along
Be axially arranged with multiple position limiting slide blocks 61, mounting platform 3 is correspondingly provided with quantity identical limited impression 31, position limiting slide block 61 with it is spacing
Groove 31, which cooperates, ensures that both position relationships will not be offset.
As shown in figure 5, cone excavation portion 11 is made up of two hemicones 111, the hemicone 111 refers to along cone
Cone is cut into two volume size identical structures by height.
As shown in fig. 6, the present invention is as follows for the punching of soil moisture measurement and the control method of measurement integrated device：
Step 1, position-limiting tube 6 is placed in the hole of moisture to be measured first；
Step 2, the limited impression 31 of the position limiting slide block 61 by position-limiting tube 6 and mounting platform 3 cooperate so that punching probe
1 is accurately located at hole bottom precalculated position；
Step 3, control receiver start punching motor 14 and rotated forward, and cone excavation portion 11 excavates downwards pre- by the transmission of power
Punching；
Step 4, control receiver start punching motor 14 and inverted so that punching probe 1 recovers to step 3 beginning
