As shown in Figure 1 to 4, soil sampling makes perforating device, including a punch 1 and one covers plate 2.Punch 1
Including perforated board 11, there is punching nail 10 in perpendicular and array distribution on an end face of perforated board 11.Plate 2 is covered for covering
To the perforated surfaces for taking native frame, the plate 2 that covers is equipped with the first nail hole 20 to match with punching nail 10.
When carrying out punching processing to soil sampling, the perforated surfaces of sample should place upward, will cover plate 2 and be covered on punching
On face, punch 1 is picked up, alignment punching follows closely 10 and covers the first nail hole 20 to match on plate 2 therewith, presses straight down
Soil sampling is punched, after the completion of punching, pins and covers plate 2, extracts punch 1 immediately, determines that punching nail 10 pulls out completely
It unclamps again and removes after soil sampling out and cover plate 2.
Using the punch 1 with punching nail 10, the distance between punching nail 10 is fixed and is met and makes to soil sampling
When pitch-row requirement, by perforated board 11 pressing in the perforated surfaces of soil sampling, so as to disposably to soil sampling carry out
The punching of batch saves plenty of time and manpower relative to the mode that can only be punched one by one manually, and ensure that hole

On face, soil will not be carried over when ensure that nail pulling, so that the fastening for maintaining soil sampling is not loose, improve soil sampling
The success rate of production.
Since the length of punching nail 10 is more long and thin, and it is larger to make density, and nail is punched in punch manufacturing process
10 mostly use welding with perforated board 11, due to mismachining tolerance may result in punching follow closely it is 10 not vertical with perforated board 11, or
It is with punch prolonged use, simultaneously because particle inside soil and uneven, so can be caused to punching nail 10
The extruding force of different angle, causes the inclinations or bending of 10 nail bodies of punching nail, thus influence to the punching depth of soil sampling and
Spacing causes the production of soil sampling to fail, and skew occurs in punching nail 10, matches to influence punching nail 10 with the first nail hole 20
It closes.So being equipped with perpendicular fixation crimp 12, the fixed crimp towards punching nail 10 at the opposite both ends of perforated board 11
12 inner clamps are equipped with an adjustable plate 3 for being parallel to perforated board 11, and the adjustable plate 3 is equipped with second to match with punching nail 10
Nail hole 30, and punching nail 10 passes through the second nail hole 30.

I.e. the diameter of the second nail hole 30 and spacing are identical as punching nail 10.Adjustable plate 3 can clamp punching nail 10 always in the structure,
So that it is always maintained at vertical state, to will not deform, ensure that the accuracy of punching.And due to adjustable plate 3
Setting, when being also beneficial to punching nail 10 with the welding of perforated board 11, punching nail 10 keeps the state vertical with perforated board 11.
Since the content of soil is more complicated and composition particle is loose, it is easy to fall off, therefore carried out to soil sampling
The consistent of Sample thickness size is not ensured that when acquisition, so needing to punch when carrying out punching processing to soil sampling
Depth can also generate difference.The both ends that the adjustable plate 3 is contacted with fixed crimp 12 are equipped with the adjusting crimp towards perforated board 11
31, since punch 1 is when being punched, the distance between two fixed crimps 12 are that it uses length, if therefore adjusting curved
Side 31 will cause towards taking native frame direction to be arranged and become the distance between two adjusting crimps 31 using length, so that length be made to contract
Short, especially when taking native width of frame direction equal with 1 length direction of punch, influence is the most obvious, therefore is arranged and adjusts crimp 31
Towards native frame direction is taken, it is constantly in it and takes above native frame, will not influence the use length of punch 1.In addition, the adjusting
Crimp 31 is equipped with fixation hole 310, and the fixed crimp 12 is equipped with the strip-shaped hole 120 opened up along punching 10 length directions of nail,

The perforated surfaces of sample will cover when plate 2 is covered in perforated surfaces close to plane and be easy to produce sliding, cause the second nail hole
30 position generates movement, further results in the dislocation of punching, even results in the failure of soil production, therefore it is curved to be provided with detent
Two adjacent upright faces of sample are blocked on side 21, to secure the position for covering plate 2, so that it will not generate sliding again to cause hole
Displacement, and due to the volume of soil sampling difference, only be provided with two adjacent detent crimps 21, in addition both sides are still adopted
With open form, no matter therefore the volume of soil sampling how to change, one angle can be blocked to be fixed on by covering plate
In perforated surfaces, will not occur covering plate 2 and the stuck situation of soil sampling.
It needs to hold punch 1 with hand when punching soil sampling and punch, therefore in the another of perforated board 11

When 20 quantity, being connected with above the punch 1 can drive it along covering 2 length direction of plate and up and down direction moves
Press machine.
The process for automatically completing punching processing is realized, solves the problems, such as that soil sampling volume is larger, saves people
Power in turn ensures the completion of punching processing.As preferred form of the invention, beaten using each column of length direction on punch 1
The quantity of hole nail 10 is than or equal to the form for covering the quantity of the first nail hole of each column 20 of width direction on plate 2, is being beaten
When the behaviour's processing of hole, punch 1 needs from left to right successively batch punching, and the track of punching is intuitively easy to operate, can more improve and beat
The accuracy and applicability of hole processing.
Since punching nail 10 needs to need to deposit between the first nail hole 20 and punching nail 10 into and out plate 2 is covered
Opposite sliding is carried out in certain interval, and also to prevent soil to be carried over from gap, as present invention further optimization,
Gap between first nail hole 20 and punching nail 10 is 0.1~0.25mm.The diameter of the first nail hole 20 is set to be greater than punching nail
10 diameter, and gap is smaller is not enough to that soil is allowed to pass through, and meets use demand.
Likewise, being needed also exist between the second nail hole 30 and punching nail 10 since adjustable plate 3 can move up and down
Certain interval carries out opposite sliding, and in order to make punching 10 not run-off the straights of nail, described as present invention further optimization
Gap between second nail hole 30 and punching nail 10 is 0.1~0.25mm.It is minimum that such gap generate punching nail 10 can only
