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 survey
Probe 2 is measured, 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, right therewith
The measurement probe 2 answered also is two pieces；Two pieces of punching probes 1 work simultaneously, and two pieces of measurement probes 2 also work simultaneously.Punch probe 1
After punching, measurement probe 2 being discharged automatically and carries out soil moisture measurement, avoiding measurement probe 2 needs independently into pre-
Damaged in punching or when entering pre-perforated by chad.
Specifically, punching probe 1 includes cone excavation portion 11, mobile link portion 12, is fixedly connected with portion 13 and punches
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Shutting mechanism 4 will measure probe 2 and be discharged or be withdrawn.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 to be fixed, and refers to it with punching the output of motor 14
End is fixedly connected, and in the presence of motor 14 is punched, is fixedly connected with portion 13 and is rotated, and by threaded function in mobile link
Portion 12 also rotates, and 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, from
And realize flexible.So mobile link portion 12 and the bar structure for an appearance is needed in the portion that is fixedly connected 13 being covered with screw thread, separately
One tubular structure for being covered with screw thread for inside.The length of both screw threads can be entered with the movable length of installation requirement mobile link portion 12
Professional etiquette is determined.
Operation principle is as follows：When wireless control receiver is by instructing startup punching motor 14, punching motor
14 rotate forward, and driving is fixedly connected with portion 13 and also rotated forward, and finally cause the rotation of mobile link portion 12 to stretch out, the lower end of mobile link portion 12
Cone excavation portion 11 starts to punch by way of rotation in soil.After punching, wireless control receiver passes through finger
Order starts punching motor 14 and inverted, and the rotation of mobile link portion 12 is retracted, and cone excavation portion 11 is also lifted.Similarly, if
After being opened in cone excavation portion 11, the punching reversion of motor 14 can to measure 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, release measurement probe actuation motor 45 are fixed on the inwall of mobile link portion 12, released
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 rotates；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 with reference to above-mentioned mobile link portion 12 and is fixedly connected with portion 13 with the operation principle of expansion link 41
Operation principle.The advantages of selecting 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, in order to avoid stuck or abrasion may insure that cone is dug using flexible hollow tube 43
Open smooth in pick portion 11.
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,

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 inverts, and each hemicone 111 needs
Restore to the original state, so being each used to help hemicone 111 provided with a back-moving spring 46 between hemicone 111 and mobile link portion 12
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, the present invention, which is used for the punching of soil moisture measurement and measurement integrated device, also includes 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, cooperated by the position limiting slide block 61 of position-limiting tube 6 and the limited impression 31 of mounting platform 3 so that punching
Probe 1 is accurately located at the bottom of hole.
Step 3, wireless control receiver start punching motor 14 and rotated forward, cone excavation portion 11 by the transmission of power to
Lower excavation is pre-perforated.
Step 4, wireless control receiver start punching motor 14 and inverted so that punching probe 1 recovers to step 3 to open
Original state before beginning.
Step 5, wireless control receiver start release measurement probe actuation motor 45 and rotated forward, the biography that expansion link 41 passes through power
It is dynamic to open cone excavation portion 11 so that the measurement down going channel of probe 2 is unobstructed.
Step 6, wireless control receiver start punching motor 14 and further inverted so that punching probe 1 and its cone
Body excavation portion 11 moves up, final that measurement probe 2 is fully contacted with pre-perforated bottom soil.
Step 7, wireless control receiver start drimeter and carry out the collection of data, and are stored in controlled in wireless reception
In device.
Step 8, data acquisition are finished, and mounting platform 3 is lifted by extension rod 5.
Step 9, wireless control receiver start punching motor 14 and rotated forward so that punching probe 1 recovers to above-mentioned first
Beginning state.
Step 10, wireless control receiver start release measurement probe actuation motor 45 and inverted, and close cone excavation portion 11.
Step 11, mounting platform 3 and punching probe 1 are taken out from position-limiting tube 6.
If pre-perforated depth can not be by once completing, can be with repeat step 3-4.
