The water yield is larger, can coordinate and somewhat be dried up with hair-dryer.Therefore, the existing method base differentiating whether the native bar sample being obtained is qualified
The artificial operation judges of this dependence, less efficient, and then have influence on the whole efficiency preparing soil sample.
By setting touching mechanism for identifying, when rubbing finishes, the 3rd electric motor starting, motor shaft rotates, and drives reel for rope to turn
Dynamic, pull plate is pulled out from fixed plate by drawstring stress, and motor shaft is rotated further, and underlying pushing touched first by quarter butt
Plate, and lower platen is turned over downwards, the region that the native bar being now placed on pull plate is rolled under lower platen is in vacant state,
Motor shaft is further continued for rotating, and stock is gently touched lower firming bar and stopped operating, if now native bar occurs line interruption,
Reach crack and the state rupturing that specification specifies, soil bar remaining on mainboard can have been taken out and carry out moisture determination.As
After fruit gently touches not there is line interruption in soil bar, but bends, then undesirable on native bar, motor shaft is pressed anti-
Direction rotates, and returns initial condition, and lower platen also returns to home position because the elastic force of elastic hinge acts on.Thus realize right
Differentiate the mechanization running of the whether qualified step of native bar sample, and then improve the whole efficiency of the native bar sample of preparation.
After stock touches native bar and carries out slight pushing, the 3rd motor stalls, that is, the 3rd motor is in work
It is rotation-limited when making, when being in limit point, stock and mainboard should be at sustained height, or its difference in height is less than 3mm.Above-mentioned
3rd motor rotation speed is slower, and during especially under stock, firming bar is outer peripheral, observing native bar is the destruction that bends
Or the bending damage of straight line, even if if it is too fast, native bar be not reaching to crack and fracture state it is also possible to because
The power momentum that stock applies ruptures greatly very much, and impact differentiates result.Further, the lower firming of the extremely slow touching of stock
, there is a certain distance with mainboard outward flange, be greater than 6mm in bar, prevent pure shear and destroy, the effect so differentiating is more
For ideal.

Motor.Lifting body also includes decelerator 281, and one end of decelerator 281 is connected with the first motor 28, the other end and linear guides
21 drive end connects.
Be conducive to carrying out numerical control using motor.In the whole process of lifting body jacking, the time would generally continue 1
～4min, and the distance of jacking only has several millimeters, therefore, the jacking required precision of above-mentioned strip rubbing instrument is significantly larger than standard machinery knot
Structure, but also there is certain defect in the fluency of stability under extreme low-speed situations for the motor and power output, for this reason,
In preferred embodiment, by the way of motor, decelerator and clinohedral work in coordination with deceleration, in order to improve the top of strip rubbing instrument
Rise precision.Specifically, for example, carry out speed governing initially with modes such as numerical controls to motor, motor is made to be in
Stable rotary regimes, in order to reach the revolution of outfan, are slowed down using the speed reducing ratio that decelerator carries out 1:6 1:10,
Make rotation process more steady；Employ clinohedral simultaneously and carry out 100:7 deceleration, with the Stroke Control jacking of clinohedral away from
From, above three structure work in coordination with slow down in the presence of, make lifting body reach low speed, the demand of steady jacking, carry further
High precision and stability.
Further, in another particular embodiment of the invention, upper plate 31 lower surface is covered with hydrophobic macromolecular material
Layer.Lower plate 27 upper surface is covered with clouded glass layer.Hydrophobic macromolecular material layer flexibility is moderate, compressible, effectively prevents from having
The native bar of certain humidity and upper plate stick together, it is to avoid upper plate kinetic equation loss and situation about being short of power.Clouded glass layer is then
