Embodiment.
Referring to Fig.1-3, a kind of geologic prospect drawing out soil equipment, the sampler barrel 9 including bottom end opening, the bottom end of sampler barrel 9
It is threaded with the aggregate bin 1 of taper, the top of aggregate bin 1 is equipped with opening, and aggregate bin 1 and sampler barrel 9 are interconnected, sampler barrel
9 bottom end two sides are provided with vertically disposed feed inlet 4, the bottom end of sampler barrel 9 company of sliding on the side inner wall of feed inlet 4
It is connected to vertically disposed baffle 5, baffle 5 and feed inlet 4 cooperate, and the top of baffle 5 is fixed with horizontally disposed connecting plate
6, the top two sides of connecting plate 6 are respectively and fixedly provided with vertically disposed telescopic rod 7, and the top of telescopic rod 7 passes through in the top of sampler barrel 9
Wall is fixed with horizontally disposed fixed ring 10, and the middle position of fixed ring 10, which is run through, is equipped with vertically disposed compression bar 8, compression bar 8
Bottom end sequentially passes through the top outer wall of sampler barrel 9 and connecting plate 6 is fixed with horizontally disposed connecting rod 12, the bottom end of connecting rod 12
Two sides are respectively and fixedly provided with link block 11, and the bottom end of link block 11 is fixed with horizontally disposed pin shaft 13, pin shaft 13 and connecting rod 12
Both ends are slidably connected at respectively on the bottom end inner wall of sampler barrel 9, and there are two be obliquely installed for the middle position rotation connection of pin shaft 13
Movable plate 16, two movable plates 16 are inverted V shaped, and the bottom end of movable plate 16, which is hinged with close to the side of baffle 5 by hinge, inclines
The mounting plate 17 being tiltedly arranged, the side wall middle position of movable plate 16 are provided with perforative limiting slot 14, are slidably connected in limiting slot 14
There is horizontally disposed gag lever post 15, the both ends of gag lever post 15 are separately fixed on the bottom end two sides inner wall of sampler barrel 9, aggregate bin 1
Inner wall middle position be fixed with horizontally disposed fixed plate 2, the bottom end two sides of pin shaft 13 are respectively and fixedly provided with vertically disposed spring
3, the bottom end of spring 3 is fixed in fixed plate 2, and the gradient of mounting plate 17 and movable plate 16 is 40-50 °, the bottom of mounting plate 17
It holds the side side wall far from movable plate 16 to be equipped with the tooth mouth being uniformly arranged, is provided on the bottom end two sides inner wall of sampler barrel 9 vertical
The sliding slot being directly arranged, the both ends of connecting rod 12 are equipped with sliding block, and sliding block is slidably connected in sliding slot.
Working principle：When carrying out that soil is taken to sample, sampler barrel 9 is inserted into soil by the aggregate bin 1 of taper, this mistake
Baffle 5 covers feed inlet 4 in journey, will not have soil to enter in sampler barrel 9 before reaching determining depth, and sampling precision is high, when
When reaching determining depth, fixed ring 10 is lifted up, telescopic rod 7 drives baffle 5 to move upwards by connecting plate 6, to beat
It drives material mouth into, then shortens telescopic rod 7, be overlapped on sampler barrel 9 so that fixed ring 10 moves downward, prevent from influencing compression bar 8 just
Often work, by moulded rod 8, connecting rod 12 drives pin shaft 13 to move downward by link block 11, at this time connecting rod 12 and pin shaft 13
It is slided on the inner wall of sampler barrel 9, since movable plate 16 and gag lever post 15 are rotatablely connected, when pin shaft 13 drives movable plate 16

When plate 16 is intended to horizontal direction, mounting plate 17 extends to the outside of sampler barrel 9, the tooth mouth on mounting plate 17 by feed inlet 4
Soil is scraped, as the amplitude that movable plate 16 and mounting plate 17 rotate is increasing, soil is in inclined mounting plate 17
It slides under the action of movable plate 16 to sampler barrel 9, compression bar can be shaken as needed, soil can be from the two sides of movable plate 16
Into in aggregate bin 1, during this, spring 3 is compressed, and gag lever post 15 slides in limiting slot 14, and limiting slot 14 is activity
The rotation of plate 16 provides activity space, lifts compression bar 8, and mounting plate 17 is rotated backward with movable plate 16, due to mounting plate 17 and lives
Movable plate 16 is hinged by hinge, and mounting plate 17 can be bent under the blocking of soil, is reduced when mounting plate 17 resets
Feed inlet 4 after the completion of sampling, is covered by telescopic rod 7 and baffle 5, can will be sampled to reduce labor intensity by frictional force
Cylinder 9 takes out, and the present apparatus can not only close feed inlet 4, prevent soil from entering sampling before sampling reaches and determines depth
In cylinder 9, to influence sampling precision, additionally it is possible to when reaching depth selection, effectively be scraped, be made to the biggish soil of hardness
It obtains soil to be stripped and enter in sampler barrel 9, sampling effect is good, and sampling efficiency is high.
