Description

Sampling device for soil detection

Technical Field

The invention belongs to the technical field of soil detection, and relates to a sampling device for soil detection.

Background

Soil environment monitoring refers to important measures for understanding the quality condition of a soil environment, aims to prevent and treat soil pollution hazards, dynamically analyzes and determines the soil pollution degree and the development trend, comprises the current situation investigation of the soil environment quality, the investigation of the background value of the regional soil environment, the investigation of soil pollution accidents and the dynamic observation of polluted soil, generally comprises the steps of preparation, distribution, sampling, sample preparation, analysis and test, evaluation and the like, and quality control/quality assurance should be performed all the time.

In-process at soil sampling, need dig the soil of getting different regions, the different degree of depth to sample detection, but because the outside plant in soil covers, the sample is difficult, directly digs with the spade and gets, and is hard taking trouble, consequently needs design a light, succinct, laborsaving soil sampling device.

Disclosure of Invention

The invention aims to provide a sampling device for soil detection, which solves the problems in the prior art.

The technical scheme adopted by the invention is that the sampling device for soil detection comprises a fixing plate, wherein a plurality of supports are uniformly hinged to the lower surface of the fixing plate, a fixing rod is hinged to the tail end of each support, and the lower part of each fixing rod is connected with a ground grab; the middle of the fixed plate is vertically provided with a sampling component.

The present invention is also characterized in that,

the sampling component comprises a screw rod barrel, a screw rod is fixedly connected to the lower portion of the screw rod barrel, a rubber pad is mounted inside one end of the screw rod barrel, a first handle is fixedly connected to the outer side wall of the other end of the screw rod barrel, a spoon digging rod is arranged inside the screw rod barrel in a penetrating mode, a spoon is fixedly connected to one end, close to the screw rod, of the spoon digging rod, a second handle is fixedly connected to one end, close to the first handle, of the spoon digging rod, and the second handle extends out of the screw rod barrel.

The rubber pad is cut with the cross breach, and the spoon can stretch out from the cross breach.

The outer wall of the screw cylinder is provided with threads.

Each fixed rod and the corresponding ground grab are in threaded connection.

The sampling device for soil detection of the invention has at least the following beneficial effects,

firstly, the ground grab is adopted, so that the ground grab can be firmly inserted into the ground, and the bracket is fixed, so that the sampling of soil is facilitated; the bracket, the fixed rod and the fixed plate are directly hinged, and the angles among the bracket, the fixed rod and the fixed plate can be adjusted, so that the sampling device is suitable for narrow spaces; meanwhile, after sampling is finished, the bracket and the fixed rod can be folded, so that the portable sampling device is convenient to carry;

secondly, the screw rod is arranged at the bottom of the screw cylinder, so that the screw rod can conveniently drill into soil for sampling, and the outer wall of the screw cylinder is provided with threads which can rotate so as to change the relative position of the screw cylinder and the fixed plate and conveniently enter the soil;

thirdly, the rubber pad is provided with a cross-shaped notch, so that the digging spoon can conveniently extend out through the cross-shaped notch and enter a hole drilled by the screw rod to take a soil sample;

fourthly, the device has simple structure and convenient carrying, and integrates drilling and sampling; the foldable bracket can be folded, the angle of the bracket can be adjusted, and the bracket is suitable for sampling in small space.

Detailed Description

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

The invention discloses a sampling device for soil detection, which comprises a fixing plate 5, wherein a plurality of brackets 4 are uniformly hinged to the lower surface of the fixing plate 5, a fixing rod 2 is hinged to the tail end of each bracket 4, and the lower part of each fixing rod 2 is connected with a ground claw 1; the middle of the fixed plate 5 is vertically provided with a sampling component.

The sampling component comprises a screw rod barrel 6, a screw rod 11 is fixedly connected to the lower portion of the screw rod barrel 6, a rubber pad 10 is arranged at one end of the screw rod barrel 6, a first handle 7 is fixedly connected to the outer side wall of the other end of the screw rod barrel 6, a spoon digging rod 9 is arranged inside the screw rod barrel 6 in a penetrating mode, a spoon 3 is fixedly connected to one end, close to the screw rod 11, of the spoon digging rod 9, a second handle 8 is fixedly connected to one end, close to the first handle 7, of the spoon digging rod 9, and the screw rod barrel 6 is extended out of the second handle 8.

Rubber pad 10 is cut with the cross breach, and the spoon 3 can stretch out from the cross breach.

The outer wall of the screw cylinder 6 is provided with threads.

Each fixing rod 2 and the corresponding ground grab 1 are in threaded connection.
