Detailed Description

The technical solutions in the present embodiments will be clearly and completely described below with reference to the accompanying drawings in the present embodiments, which, however, should not be construed as limiting the present invention to specific embodiments, but are for explanation and understanding only:

as shown in fig. 1 and fig. 2, the present embodiment provides a portable heavy metal sampler for environmental detection, which includes a sampling tube 1, a supporting column 2, a handle 3, and a sampling sleeve 4.

The top end of the sampling tube 1 is closed and provided with an exhaust hole, and the exhaust hole is used for ensuring that the air pressure inside and outside the sampler is consistent when sampling; the outer annular wall of sampling pipe 1 bottom is opened there is the joint groove, the lateral wall that the joint groove kept away from sampling pipe 1 bottom is opened has several extending groove 5, and the several is kept away from its tank bottom in the extending groove 5 and is gone out and be equipped with dog 6.

The sampling sleeve 4 comprises an inner cavity part 41, a puncture part 42 and a clamping part 43 which are sequentially connected, the inner cavity part 41 is barrel-shaped, the top end of the inner cavity part 41 is closed and provided with an exhaust hole, the outer annular wall of the inner cavity part 41 is in contact with the inner wall of the sampling tube 1, a plurality of clamping teeth 7 are processed on the inner annular wall of the inner cavity part 41, the plurality of clamping teeth 7 are continuously arranged along the axial direction of the inner cavity part 41, each clamping tooth 7 is provided with an inclined wall and a supporting wall, the supporting arm wall is perpendicular to the inner wall of the inner cavity part 41, the inclined wall is positioned on one side, far away from the vent hole, of the supporting arm, and each clamping tooth 7 has certain supporting force on soil entering the inner cavity part 41, so that the possibility that the soil entering the.

Joint portion 43 is the tubulose, and joint portion 43 inner ring wall and the contact of joint groove rampart, joint portion 43 and the central coaxial of inner chamber portion 41, joint portion 43 is close to the one end of extending groove 5 and is equipped with several joint board 44, is equipped with couple 45 on the joint board 44, and when joint board 44 got into extending groove 5, rotatory sampling cover 4 can make couple 45 and dog 6 match, makes sampling cover 4 can be stable must install on sampling tube 1, and the getting of sampling cover 4 of being convenient for is taken.

The puncture part 42 is annular and is located the sampling tube 1 bottom, and joint portion 43 and inner chamber portion 41 are connected to puncture part 42, the one end that the puncture part 42 kept away from inner chamber portion 41 is sharp-pointed, and the sharp-pointed one end of puncture part 42 is used for inserting in the soil. Sampling cover 4 is made by polyvinyl chloride, has the hardness, and in making soil collection, the soil of collecting can not contact with sampling pipe 1 that the metal was made, and sampling pipe 1 has stronger hardness, also can guarantee the support to sampling cover 4.

2 one end demountable installation of support column has through-hole 21 on 1 top of sampling pipe, and other end lateral wall is opened, 2 lateral walls of support column are opened and are had the standing groove 22 that is used for placing handle 3, and handle 3 accomodates conveniently portable.

Handle 3 can be dismantled and place in standing groove 22, handle 3 can insert in the through-

hole

21, 3 middle parts of handle are equipped with

joint piece
