The input terminal of earth measurement and analysis instrument 15 is connected, and soil surveying information can be passed to PLC controller 16 by measuring probe 12,
PLC controller 16 starts soil surveying analysis instrument 15, analyzes the information, obtains soil constituent data information.
It is an integral molding structure between screw rod 2, loop bar 6, helical-blade 5 and annular slipping ring 9 four.
Working principle:
In use, controlling the key of motor 20, the motor 20 of starting, so that with electricity on operating personnel's pressing operations keyboard 18
The rotary head 1 of 20 axis connection of machine and screw rod 2 can rotate, and rotate down soil, cause measurement bar body ontology 3 can be easily
Into depth of soils, when measuring rod, which reaches, to be needed to measure depth of soil, operating personnel closes motor 20, is then turned on driving at this time
Motor 14, driving motor 14 drive rotation axis 27 to rotate, and rotation axis 27 makes pitch of the laps axis 28 in the annular turn trough 23 of connecting rod 22
Interior circulation rotating causes cover plate 29 that can do cyclic rotation running centered on the center for measuring bar body 3, at the same time,
The cover board ball grooves 24 that annular ring 30 embeds in operating stick 7 rotate, and reduce the frictional force of cover board 13 and operating stick 7, so that covering
Cover board 29 can smooth rotation, soil is brought into measurement chamber 11, the measuring probe 12 installed in chamber 11 is measured and detects, measurement
The information of 12 detection of probe passes to PLC controller 16, and PLC controller 16 starts soil surveying analysis instrument 15, to the information
It is analyzed, obtains soil constituent data information, shown by display screen 19, checked for operating personnel.
In summary: a kind of soil constituent measuring rod of the present invention, rotary head 1 and screw rod 2 by setting, in insertion soil
When middle, motor 20 can be started, so that rotary head 1 and screw rod 2 rotate, cause measurement bar body 3 that can squeeze into soil depth easily
Place makes power be downwardly into measurement bar body 3, is conducive to protection bar body 3, prolongs its service life without operating personnel；
Further through the measurement bar body 3 and cover board 13 of setting, the soil constituent of several depth can be detected simultaneously, avoids traditional measurement
Bar body needs to repeat downward turn hole and measures again, in the process, be merely able to when needing to detect the soil of different depth
By the depth of the micro-judgment insertion of staff, causes every standard to fathom twice to be held not accurate enough, cause to survey
Measure not accurate enough the problem of result.
It although an embodiment of the present invention has been shown and described, for the ordinary skill in the art, can be with
A variety of variations, modification, replacement can be carried out to these embodiments without departing from the principles and spirit of the present invention by understanding
And modification, the scope of the present invention is defined by the appended.
