2. the utility model handle is gum cover form, convenient for extracting, inside carries liner form convenient for taking out soil sample, simultaneously Liner uses plastic material, not will produce metal fillings, noiseless to soil metal content analysis.

3. the pedotheque of acquisition is easy to take out, accurate measurement, preservation easy to carry.

Description of the drawings

FIG. 1 is a schematic structural view of the utility model；

Fig. 2 is the structural schematic diagram of second embodiment in the utility model.

Wherein, 1 is handle, and 2 be thief rod, and 3 be liner, and 4 be sampling head, and 5 is at hammer percussion, 6 are cushion block, and 7 be row Stomata.

Specific implementation mode

The utility model is further elaborated with reference to the accompanying drawings of the specification.

Embodiment 1

As shown in Figure 1, a kind of topsoil sampling apparatus of the utility model, including：Handle 1, thief rod 2, liner 3 and Sampling head 4, wherein thief rod 2 is cylindrical shell, and liner 3 is installed on 2 inboard of thief rod, sampling head 4 and 2 bottom end of thief rod It is threadedly coupled or card slot connection, handle 1 is installed on 2 upper end of thief rod.

There are gaps between liner and thief rod, and the gap is smaller, generally less than 1mm, and the present embodiment uses 0.8mm, with Reduce sampling resistance.

Sampling head 4 is the pyramidal structure of hollow, and base diameter is less than 2 diameter of top thief rod, and wall thickness is relatively thin, this implementation Example is made of stainless steel material, is convenient for soil collection to reduce sampling resistance；Sampling head 4 is threadedly coupled or blocks with thief rod 2 Slot connection is easily installed；Handle 1 is decussate texture, and decussate texture upper end is 5 at hammer percussion, and lower end passes through screw thread or card Slot is connected to 2 upper end of thief rod.It is cylinder that decussate texture both ends, which hold position, and outside is cased with gum cover, convenient for extracting sampling Bar 2.In order to facilitate observation of deeply, it is equipped with sampling depth scale outside thief rod.It is equipped with exhaust in the decussation position of handle 1 Hole 7 is goed deep into soil course in thief rod 2, plays the role of exhaust, pressure release.

The utility model use process is as follows：

Before waiting for soil sampling, the screw thread between thief rod 2 and handle 1 is unscrewed into (or card slot is opened), liner 3 is packed into In thief rod 2, thief rod 2 is threadedly coupled (or being clamped by card slot) with handle 1；

Soil sampler is pressed in and is waited on soil sampling position ground, is tapped 5 at percussion with hammer, by observing outside thief rod The sampling depth scale in portion, makes it drop to specified sampling depth, such as 15cm；During this, liner 3 is in sampling by handle 1 Limit is held out against, and prevents liner 3 from moving up, and is deep into soil with thief rod 2, and soil has enter into liner 3 at this time；

Thief rod 2 is extracted by handle 1, the screw thread between thief rod 2 and handle 1 is unscrewed, pours out liner 3, one time soil is adopted Collection process terminates.

Since liner is made of materials such as plastics, metal residual is not will produce in entering soil course, is effectively reduced The interference of metallic element in soil sample.

Embodiment 2

As shown in Fig. 2, the present embodiment difference from example 1 is that, including：Thief rod 2, liner 3, sampling head 4 And cushion block 6, wherein thief rod 2 is cylindrical shell, and liner 3 is installed on 2 inboard of thief rod, sampling head 4 and 2 bottom of thief rod End threaded connection or card slot are welded to connect, and sampling head 4 can also use integrated design with thief rod 2, and 6 bottom of cushion block has The groove coordinated with thief rod upper end shape, size, is removably directly mounted at 2 upper end of thief rod.

Equally, there are gaps between liner 3 and thief rod 2, and the gap is smaller, generally less than 1mm, and the present embodiment uses 0.8mm, to reduce sampling resistance.Sampling head 4 is the taper type structure of hollow, i.e., base diameter is less than upper diameter, and wall thickness It is relatively thin, it is less than thief rod 2.The present embodiment is made of stainless steel material, is convenient for soil collection to reduce sampling resistance；

In use, cushion block 6 is removed by 2 upper end of thief rod, liner 3 is packed into thief rod 2, then cushion block 6 is sleeved on and is adopted 2 upper end of sample bar；

It is tapped 5 at hammer percussion with hammer, thief rod 2 is made to drop to sampling depth, during this, liner 3 can sample It holds out against motionless by the limit of cushion block 6 inside bar 2, is deep into soil with thief rod 2, soil has enter into liner 3 at this time；

Thief rod cushion block 6 is removed, thief rod 2 is dug out with scoop, pours out liner 3, completes a soil sampling process.
