Control is closed, belongs to prior art scope, is no longer described in detail in the present embodiment.
The soil sampling apparatus to microcontroller in use, (be omitted control in the prior art first in the present embodiment
The common parts such as panel) input need moisture content range, this moisture content range can have it is multiple, in the present embodiment
There are two being arranged for sample housing unit, if necessary to the sample of two moisture content ranges of 40%-50% and 20%-30%
Product, then the microcontroller moisture content range threshold value in the sample housing unit of lower section is set to 20%-30%, by upper quadrat sampling
Microcontroller moisture content range threshold value in product housing unit is set as 40%-50% (because due to evaporating, generally
The soil water content on more upper layer is lower).Then the alignment of drill bit 26 is needed into the soil locations sampled, starting the rotation of motor 1 makes
Drill bit 26 is rotated down and slowly pierces in soil, upper shutter door 11 and lower shutter door 13 are all in closed state, i.e., two at this time
A 3/4ths plectane respectively by the left semicircle of taper convex edge 14 be open 24, the right of semi-circular plate 16 opening 25 close (such as Fig. 6 and
Closed state shown in Fig. 7).Instantly the moisture detector 20 of quadrat sampling product housing unit constantly moves down, the soil water detected
When point content enters between 20%-30%, the drilling rod position that microcontroller records 20%, 30% moisture, two nodes is (right
Answer the rotation total angle of motor 1), then motor 1 is circled round to the middle point between 20% and 30%, microcontroller 21 is controlled
The startup of miniature Dual-output shaft motor 9 is made, the position of opening-closing plate 11 and lower opening-closing plate 13 turns to as shown in Figure 6 and Figure 7 in drive
Opening state, at this time the left semicircle opening 24 of taper convex edge 14 and the right opening of semi-circular plate 16 25 be simultaneously open, before
Broken get rid of to the soil of side from the left semicircle of taper convex edge 14 opening 24 is bored by drill bit 26 to fall into, and finally enters sample storage space
In 15.With the continuous entrance of pedotheque, the gradual of sample storage space 15 is filled by soil, since sample housing unit is whole
Body is in soil, therefore in addition to the light source of light projector illuminator, there is no other light sources in sample storage space 15, when
Pedotheque is accumulated to when flooding light projector illuminator 18, and the luminosity that light-inductive device 19 receives can drastically decline, when its decline
To setting luminosity threshold value when, microcontroller 21 controls the rotation of 9 automatic reverse of miniature Dual-output shaft motor, and close synchronously taper is convex
Along 14 left semicircle opening 24 and the right opening 25 of semi-circular plate 16, stop sampling, while being latched in the sample housing unit of lower section
The action of miniature Dual-output shaft motor 9.Hereafter, drill bit 26 continues to move down, until the moisture detector of top sample housing unit
The moisture detected is fallen within the scope of 40%-50%, repeats above-mentioned sampling operation identical with lower section sample housing unit
Engineering.So far, 20%-30% and 40%- are just acquired respectively in lower section sample housing unit and top sample housing unit
The pedotheque of 50% two specified moisture content range.
The advantageous effect of the sampler：1, same position, difference can disposably be acquired by innovatively devising one kind
The sampler of the pedotheque of specified moisture content range, and the sample of these different in moisture content ranges can be separated
It is automatically stored, high degree of automation.
2, the upper opening-closing plate with synchronization action and lower opening-closing plate, can easily and effectively open and close memory space,
According to memory space without outer light characteristic, the reliably closure element based on light sensitivity is devised, can effectively prevent depositing in this way
The excessive overfill of sample in space is stored up, excessive soil enters the space where miniature Dual-output shaft motor and microcontroller
In, it influences its normal work or its damage is caused (to enter although still suffering from a small amount of soil, have substantially no effect on its normal work
Make).Since the present invention is using multiple sample storage spaces, such design relative to it is general using weight induction device come
Solid sample is judged whether for overfill, and action is relatively reliable, will not be influenced by other sample storage space soil storage amounts, energy
It effectively prevent malfunction.
3, inventor it has been investigated that, due to soil be easy the surface of light projector illuminator is polluted, long-play
The initial intensity that light-inductive device receives afterwards, which can weaken, even to fail, therefore an internal light projector illuminator surface has also been devised
Clear up component.(cleaning and maintenance should be carried out in the non-sampled period) when needing to clear up light projector illuminator surface, start electronic stretch
Contracting bar moves down, and the top that cylinder is placed on to column covers the surface of light projector illuminator, then rotates miniature Dual-output shaft motor,
So that the continuous spin friction light projector illuminator surface of the cavernous body of inner barrel is cleared up.
Finally it should be noted that the above embodiments are merely illustrative of the technical solutions of the present invention, rather than the present invention is protected
The limitation of range is protected, although being explained in detail to the present invention with reference to preferred embodiment, those skilled in the art answer
Work as understanding, technical scheme of the present invention can be modified or replaced equivalently, without departing from the reality of technical solution of the present invention
Matter and range.
