Description

Sapling root sampling tool

Technical Field

The utility model relates to a sapling root sampling tool.

Background

The sampling pattern for analyzing the test sample may vary depending on the object of analysis. Where the representativeness of the sample is crucial, otherwise a completely wrong conclusion may be reached. In the experimental study of sapling and nursery stock, the root of sapling and soil sample are often taken to carry out chemical analysis, so as to comprehensively know the content level of the measured component in soil and root and the change of the operation condition of the measured component. Compared with crops, the roots of the saplings are large and deep, and the saplings can be taken out by digging soil. Thus, the sampling site (depth and range) of the soil is damaged, and the sampling accuracy is affected. In consideration of the characteristics of field sampling, a simpler sampling tool is also needed, and the sampling tool is convenient to carry and use.

The utility model discloses improve above-mentioned problem, promptly the to-be-solved technical problem of the utility model is that sapling root and soil sample adopt to dig out the soil mode and carry out the precision inaccurate among the experimental research of current sapling nursery stock.

The utility model discloses a concrete implementation scheme is: the utility model provides a sapling root sampling tool, includes the sampling tube, overlaps in the solid drum at sampling tube top, and runs through the horizontal pole of solid drum and sampling tube, the sampling tube bottom has continuous bellied sharp-pointed portion along the circumferencial direction, solid drum top and sampling tube top parallel and level, horizontal pole outside both ends respectively have a round hole for connect the stay cord.

Furthermore, the inner diameter of the sampling pipe is 15-25cm, and the length of the sampling pipe is 75 cm.

Further, the sampling tube is made of a hard material.

Further, the solid cylinder has a height of 20 cm.

Furthermore, the outer surface of the cross rod is provided with external threads, and the cross rod is in threaded connection with a pair of nuts for limiting the cross rod.

Furthermore, a sleeve is sleeved outside the cross rod.

Compared with the prior art, the utility model discloses following beneficial effect has: sampling tool, simple structure, non-electric drive be convenient for field usage, carry and convenient to use, can get sapling root, rhizosphere soil and non-rhizosphere soil sample simultaneously, effectively improve sampling efficiency and precision.

Fig. 1 is the utility model discloses a sapling root sampling tool.

Wherein, 1-sampling tube, 2-solid cylinder, 3-cross bar, 4-round hole, 5-nut, 6-sharp part.

Detailed Description

The present invention will be described in further detail with reference to the accompanying drawings and specific embodiments.

As shown in figure 1, a sapling root sampling instrument, including sampling tube 1, cover in the solid cylinder 2 at sampling tube top, and run through the horizontal pole 3 of solid cylinder and sampling tube, the sampling tube bottom has continuous bellied sharp-pointed part 6 along the circumferencial direction, solid cylinder top and sampling tube top parallel and level, horizontal pole outside both ends respectively have a round hole 4 for connect the stay cord.

In this embodiment, the horizontal pole surface has the external screw thread, and threaded connection has a nut 5 of a pair of spacing horizontal pole on the horizontal pole, thereby supports the surface of top sampling tube through the nut during installation and lock the horizontal pole 3 that runs through solid cylinder and sampling tube.

In order to enable the sampling tube 1 to smoothly enter the soil and avoid soil pollution in the embodiment, the sampling tube 1 is made of a non-metal hard material, a sharp part adopts continuous angular protrusions as shown in fig. 1 so as to be beneficial to reducing resistance to cutting the soil, the inner diameter of the sampling tube is 15-25cm, the length of the sampling tube is 75cm, and the inner diameter of the sampling tube 1 in actual design can be adjusted according to the age of a seedling to be taken.

The solid cylinder 2 is sleeved on the upper part of the sampling tube, so that the upper part of the sampling tube 1 is of a solid structure, and the purpose is to knock the upper part of the sampling tube to penetrate into the soil layer. The solid cylinder 2 has an outer diameter slightly smaller than the inner diameter of the sampling tube 1 so as to be capable of being just inserted into the sampling tube 1, and has a length of 20 cm.

The hand is prevented from being hurt when the operation is applied with force, and the outer layer is provided with a soft sleeve.

The utility model discloses method and process when in actual use as follows:

the specific operation steps are as follows:

(1) removing the overground part of the sapling, aligning the center of the sampling tube 1 to the center of the root, and pressing the sampling tube into soil with the root as the center for sampling by means of the alternative or combined operation of the raised sharp part 6 at the bottom end of the sampling tube, the rotating cross rod and the beating solid cylinder;

(2) then the sampling tube is taken out of the soil by rotating the cross rod and the pull rope, and the pull rope is connected with the round holes at the two ends of the outer side of the cross rod and can be pulled to be lifted or sleeved on the shoulder of an operator to exert force to finish sampling;

(3) knocking the top of the sampling tube to drop the root of the sapling and the soil;

(4) and separating the roots from the soil, obtaining rhizosphere soil by a shaking-off method, and taking the rest non-rhizosphere soil after sampling.

Any technical solution disclosed in the above utility model is, unless otherwise stated, a numerical range if it is disclosed, and the disclosed numerical range is a preferred numerical range, and any person skilled in the art should understand that: the preferred ranges are merely those values which are obvious or representative of the technical effect which can be achieved. Because numerical value is more, can't be exhaustive, so the utility model discloses just disclose some numerical values with the illustration the technical scheme of the utility model to, the numerical value that the aforesaid was enumerated should not constitute right the utility model discloses create the restriction of protection scope.

The utility model discloses if disclose or related to mutual fixed connection's spare part or structure, then, except that other the note, fixed connection can understand: a detachable fixed connection (for example using bolts or screws) is also understood as: non-detachable fixed connections (e.g. riveting, welding), but of course, fixed connections to each other may also be replaced by one-piece structures (e.g. manufactured integrally using a casting process) (unless it is obviously impossible to use an integral forming process).

In addition, terms used in any one of the technical aspects of the present disclosure to indicate positional relationships or shapes include, unless otherwise stated, states or shapes similar, analogous or close thereto.

The utility model provides an arbitrary part both can be assembled by a plurality of solitary component parts and form, also can be the solitary part that the integrated into one piece technology was made.
