Specific embodiment
With reference to Fig. 1 to Fig. 6, the present invention will be further described：
As shown in Figure 1, it is a kind of for the punching of soil moisture measurement and measurement integrated device, 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 at the same time, and two pieces of measurement probes 2 also work at the same time.Punch probe 1
After punching, measurement probe 2 being released automatically and carries out soil moisture measurement, avoiding measurement probe 2 needs independently into pre-
It is damaged in punching or when entering pre-perforated by chad.
Specifically, punching probe 1 includes cone excavation portion 11, mobile connection portion 12, is fixedly connected with portion 13 and punches
Driving motor 14, punching driving motor 14 output terminal be connected with being fixedly connected with 13 one end of portion, be fixedly connected 13 other end of portion and
12 one end of mobile connection portion is attached by screw thread, and mobile connection portion 12 stretches under being rotated in the portion that is fixedly connected 13.It moves
12 other end of rotation connection is connected by connecting shaft 15 with cone excavation portion 11.It is 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Shutting mechanism 4 will measure probe 2 and be discharged or be withdrawn.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 driving motor 14
End is fixedly connected, and under the action of driving motor 14 is punched, is fixedly connected with portion 13 and is rotated, and pass through threaded function in mobile connection
Portion 12 makes its rotation, it is caused to change with being fixedly connected with the threaded connection length of portion 13 in 12 rotation process of mobile connection portion,
So as to fulfill flexible.So mobile connection portion 12 with need that there are one appearances to be covered with the rod structure of screw thread in the portion that is fixedly connected 13,
Another is covered with the tubular structure of screw thread for inside.The length of the two screw thread can be wanted according to 12 movable length of mobile connection portion
It asks and is provided.
Operation principle is as follows：Start punching driving motor 14 by instructing when controlling and receiving device, punching driving motor 14 is just
Turning, driving is fixedly connected with portion 13 and also rotates forward, finally so that the rotation of mobile connection portion 12 is stretched out, the cone of 12 lower end of mobile connection portion
Excavation portion 11 starts to punch by way of rotation in the soil.After punching, control and receive device and beaten by instructing to start
Hole driving motor 14 inverts, and the rotation of mobile connection 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 driving motor 14 can to measure probe 2 in pre-perforated.
As shown in Fig. 2, cone excavation portion switching mechanism 4 includes telescopic rod 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 12 inner wall of mobile connection portion, release
The output terminal for putting measurement probe actuation motor 45 is connected with fixed 42 one end of riffled tube, and fixed 42 other end of riffled tube is with stretching
41 one end of contracting bar is attached by screw thread, and telescopic rod 41 stretches in the case where fixed riffled tube 42 rotates；Flexible hollow tube
43 are fixed on the inner wall in cone excavation portion 11, and 41 other end of telescopic rod enters directly open-top cone in flexible hollow tube 43 and excavates
Portion 11 passes through the indirect open-top cone excavation portion 11 of flexible hollow tube 43.
Fixed riffled tube 42 with reference to above-mentioned mobile connection portion 12 and is fixedly connected with portion 13 with the operation principle of telescopic rod 41
Operation principle.The advantages of selecting flexible hollow tube 43 is：When avoiding 41 open-top hemicone 111 of telescopic rod, telescopic rod 41 with
111 contact position of hemicone 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 of two hemicones 111, and each hemicone 111 is equipped with a flexible hollow tube 43,
Each hemicone 111 is connected by a connection shaft 15 with mobile connection portion 12.
The unlatching of two hemicones 111 measures probe actuation motor 45 by a release and realizes；Concrete structure is：It is flexible
Bar 41 is connected by connecting annulus 44 with a mandril, and measurement probe 2 passes through connection annulus 44；Telescopic rod 41 and a hemicone
Flexible hollow tube 43 on 111 coordinates, and mandril coordinates with another flexible hollow tube 43 on another hemicone 111.It is above-mentioned to stretch
Contracting bar 41 and mandril share a motor and drive, and can save space-efficient setting, and can also save manufacture cost, can be with
Ensure that telescopic rod 41 works asynchronously always with mandril 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
It restores to the original state, so being each used to help hemicone 111 equipped with a resetting spring 46 between hemicone 111 and mobile connection portion 12
Cone structure can be reverted to after being opened.
As shown in figure 3,12 surface of mobile connection portion is equipped with the spiral groove 16 that soil is facilitated to export.
As shown in figure 4, the present invention further includes mounting platform 3 for the punching of soil moisture measurement and measurement integrated device,
Punching driving 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, further including a position-limiting tube 6, entire pipe shaft is buried in the soil；6 inner wall of position-limiting tube along
It is axially arranged with multiple position limiting slide blocks 61, mounting platform 3 is correspondingly provided with the identical limiting groove 31 of quantity, position limiting slide block 61 and /V
Groove 31, which cooperates, ensures that the position relationship of the two will not deviate.
As shown in figure 5, cone excavation portion 11 is made of two hemicones 111, the hemicone 111 refers to along cone
Cone is cut into two identical structures of volume size 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：
Position-limiting tube 6 is placed in the hole of moisture to be measured by step 1 first；
Step 2 is cooperated by the position limiting slide block 61 of position-limiting tube 6 and the limiting groove 31 of mounting platform 3 so that punching
Probe 1 is accurately located at hole bottom precalculated position；
Step 3, control and receive device start punching driving motor 14 rotate forward, cone excavation portion 11 is dug downwards by the transmission of power
It digs pre-perforated；
Step 4, control and receive device start punching driving motor 14 invert so that punching probe 1 recover to the step 3 to open
Original state before beginning；
Step 5, control and receive device start release measurement probe actuation motor 45 rotate forward, telescopic rod 41 is beaten by the transmission of power
Open cone excavation portion 11 so that measurement 2 down going channel of probe is unobstructed；
Step 6 controls and receives the further reversion of device startup punching driving motor 14 so that punching probe 1 and its cone digging
Pick portion 11 moves up, final so that measurement probe 2 comes into full contact with pre-perforated bottom soil；
Step 7, the acquisition for controlling and receiving device startup drimeter progress data, and be stored in and control and receive in device；
Step 8, data acquisition finish, and mounting platform 3 is lifted by extension rod 4；
