Embodiment: a kind of ground sampler, as shown in Figure 1, including probe tube 1 and being set in close on probe tube 1
Tube sealing 2 can be relatively rotated axially between probe tube 1 and seal pipe 2.Sample tap is offered on the outer wall of probe tube 1
11, sample tap 11 is arranged at intervals with multiple along the length direction of probe tube 1, offers out in the wherein one end of probe tube 1
Sample mouth 12.Injection port 21 is offered on the outer wall of seal pipe 2, injection port 21 is arranged along the length direction interval of seal pipe 2
Have multiple.
Operator's hand when rotating 1 perhaps seal pipe 2 of probe tube may be slided on probe tube 1 or seal pipe 2
It is dynamic, make the not very convenient of rotation, therefore one end on probe tube 1 close to outlet 12 is fixedly connected with the first swing handle
13, one end in seal pipe 2 close to sample tap 11 is fixedly connected with the second swing handle 22, the first swing handle 13 and second
For swing handle 22 perpendicular to the length direction of seal pipe 2, the first swing handle 13 is located at the top of the second swing handle 22.
As shown in Figures 2 and 3, when the first swing handle 13 and the second swing handle 22 turn to when being parallel to each other, sampling
Mouthfuls 11 and injection port 21 be staggered completely, when the first swing handle 13 and second swing handle 22 turn to when being mutually perpendicular to,
Sample tap 11 and injection port 21 are completely coincident.
In conjunction with Fig. 1, when rotating to probe tube 1 and seal pipe 2, the first swing handle 13 and second turn can be held
Dynamic handle 22 is rotated, and turns to the first swing handle 13 and when the second swing handle 22 is mutually perpendicular to, sample tap 11 and into
Sample mouth 21 is completely coincident, and the soil in soil layer is able to enter in probe tube 1；When needing to take out the device from soil layer, turn
Dynamic first swing handle 13 and the second swing handle 22 make it be parallel to each other, and sample tap 11 and injection port 21 are staggered completely, thus
When taking out the device, the soil in soil layer guarantees the accuracy of sampling, and the first turning handle not further into arriving in probe tube 1
Hand 13 and the second swing handle 22 more convenient can rotate probe tube 1 and seal pipe 2, make seal pipe 2 and sampling
Pipe 1 is not easy to slide from hand.
Operator holds the first swing handle 13 or the second swing handle 22 rotates, can be more convenient laborsaving
Carry out rotate, operate enhanced convenience, improve soil extracting efficiency.
As depicted in figs. 1 and 2, when being sampled using sampler to the soil in stratum, the first swing handle is rotated
13 and second swing handle 22 so that it is parallel to each other, sample tap 11 and injection port 21 are staggered completely, in the mistake for extending downwardly into soil layer
Cheng Zhong, soil will not enter from sample tap 11 or injection port 21, are downwardly into the device until reaching the position for wanting to take soil, revolve
Turning the first swing handle 13 and the second swing handle 22 is mutually perpendicular to it, and sample tap 11 is completely coincident with injection port 21, thus
Soil in soil layer enters in probe tube 1 from sample tap 11 and injection port 21.After the completion of to be sampled, continue the first rotation of rotation
Handle 13 and the second swing handle 22 are at the state being parallel to each other, and sample tap 11 and injection port 21 are staggered completely at this time,
To which soil sample is saved in probe tube 1, will not spill from sample tap 11 or injection port 21, by the sampler from soil layer
When taking out upwards, it there will not be soil and entered in probe tube 1 from sample tap 11 or injection port 21, ensure that the accurate of soil sample
Property, soil sample will not be contaminated, and improve sampling efficiency.
When needing to take out soil sample, which is inverted, makes side of the outlet 12 on probe tube 1 towards close ground
To, soil sample can be dumped out, and it is easy to operate, and when being transported to soil sample, soil sample is not easy out of probe tube 1
Spill, facilitates storage and transport.
As shown in Figure 1, soil is not easy to enter from sample tap 11 when the stratum harder to soil property is sampled, therefore
It is located at the two sides of injection port 21 in seal pipe 2 and the length direction of seal pipe 2 is provided with packing auger blade 23, in stratum
Soil when being sampled, rotatory sealing pipe 2, packing auger blade 23 can break up the harder soil property in stratum, thus by breaing up
Soil can be entered in probe tube 1 along injection port 21 and sample tap 11.Setting packing auger blade 23 can be such that the sampling fills
The stratum for adapting to different hardness is set to be sampled operation, keeps sampling operation enhanced convenience quick.
Preferably, packing auger blade 23 is gradually reduced along the length direction of seal pipe 2, and packing auger blade 23 is close to sample tap 11
One end be greater than packing auger blade 23 far from sample tap 11, when the device is downwardly into stratum, packing auger blade 23 is lesser
One end first contacts stratum, and the pressure between the lesser one end of packing auger blade 23 and stratum increases, the resistance when being downwardly into the device
Power is smaller, more laborsaving the device can be inserted into stratum.
As shown in Figure 1, further, it is sampled operation in order to more convenient labour-saving, it is separate in seal pipe 2
One end of outlet 12 is fixedly connected with drill bit 24, and drill bit 24 is cone, and the tip of drill bit 24 is directed away from outlet 12
Direction, the maximum gauge of drill bit 24 are greater than the outer diameter of seal pipe 2.When the stratum harder to soil property is sampled, 24 energy of drill bit
Enough to break up soil layer, the insertion for seal pipe 2 provides channel so that the sampler be downwardly into it is more smooth
It is laborsaving.
Operator is when rotating the first swing handle 13 and the second swing handle 22 in order to prevent, hand and the first turning handle
Hand 13 and the second swing handle 22 can generate sliding, therefore be provided on the first swing handle 13 and the second swing handle 22 anti-
Sliding sleeve (is not drawn into) in figure, and Anti-slip cover is capable of increasing the friction between hand and the first swing handle 13 and the second swing handle 22
Power, thus prevent in the course of rotation hand slided on the first swing handle 13 or the second swing handle 22, make operator
Member is more smoothly laborsaving during sampling.
Preferably, probe tube 1 and seal pipe 2 are all made of integrally formed stainless-steel pipe, are being sampled out of stratum
When, moisture may be contained in stratum, the prolonged use device moisture may generate probe tube 1 and seal pipe 2
Corrosion and damage is got rusty, to make to rotate difficulty between probe tube 1 and seal pipe 2, can prevent probe tube 1 using stainless-steel pipe
It gets rusty with seal pipe 2, extends the service life of the device, and can guarantee the rotation fluency between probe tube 1 and rotation pipe.
The course of work: before being sampled, rotating the first swing handle 13 and the second swing handle 22 makes it in mutual
Parallel state extends downwardly into one end with drill bit 24 in soil layer at this point, sample tap 11 is staggered completely with injection port 21,
Drill bit 24 can break up the soil in soil layer, enable seal pipe 2 is more convenient to stretch in soil layer, stretch to the device
Enter to the position of required sampling, rotating the first swing handle 13 and the second swing handle 22 is mutually perpendicular to it, at this point, sample tap
11 are completely coincident with injection port 21, and soil can enter in probe tube 1 from sample tap 11 and injection port 21, after the completion of taking soil,
It rotates the first swing handle 13 and second and rotates the state for making it restore to be parallel to each other, sample tap 11 and injection port 21 are complete at this time
It is staggered, which is taken out out of soil layer；When needing to pour soil sample, which is inverted, makes outlet 12
Towards the direction close to ground, the soil sample in probe tube 1 is dumped out, easy to operate.
This specific embodiment is only the explanation to the utility model, is not limitations of the present invention, ability
Field technique personnel can according to need the modification that not creative contribution is made to the present embodiment after reading this specification, but
As long as all by the protection of Patent Law in the scope of the claims of the utility model.
