Technical Field
The invention belongs to the technical field of sampling equipment, and relates to a handheld precise deep soil sample collecting device.
Background
When soil sampling is carried out, soil at different depths is often required to be collected. The soil sampling equipment is divided into two types according to the sampling quantity of the soil sampling equipment, one type of equipment can only collect soil with one depth at a time, the collected soil can only be generally used for simple analysis of components contained in the soil, but the sampled soil is poor in representativeness; another type of device can collect soil samples at multiple depths at one time, and although the sampling number is large, the soil at the target depth cannot be accurately collected.
Disclosure of Invention
The invention aims to provide a handheld precise depth soil sample collecting device which can accurately collect soil with multiple depths.
The invention adopts the technical scheme that the handheld precise deep soil sample collecting device comprises a sampling cylinder and a central rod which are connected through threads, wherein the central rod is positioned on a central rod line of the sampling cylinder, the bottom end of the central rod is positioned in the sampling cylinder, the top end of the central rod is provided with a handle, the handle is positioned outside the sampling cylinder, the outer wall of the sampling cylinder is provided with a plurality of sampling grooves, a sealing plate capable of moving along the length direction of the sampling cylinder is arranged in the sampling cylinder, the sampling grooves are sealed when the sealing plate extends into the limit position in the sampling cylinder, and the sampling cylinder is provided with a length scale value along the length direction of the sampling cylinder.
The present invention is also characterized in that,
the bottom of the sampling cylinder is in a conical shape.
The sampling grooves are positioned on a straight line parallel to the axis of the sampling cylinder and are uniformly distributed.
The sampling grooves are all positioned on one side of the length scale value.
A hand-push baffle is fixed at the top end of the sealing plate and is positioned outside the sampling cylinder.
The invention has the beneficial effects that:
the handheld precise depth soil sample collecting device is simple in structure and convenient to use; the soil sampler is provided with a plurality of sampling grooves, so that soil with a plurality of depths can be sampled at one time; in the sampling process, the depth can be accurately sampled according to the sampling requirement; in addition, the sampling grooves are closed before and after sampling, the samples are prevented from being mixed with other deep soil when the sampling cylinder is moved, the collected samples cannot be polluted, and the sampling groove plays an important role in accurate analysis of subsequent soil.

Detailed Description
The present invention will be described in detail below with reference to the accompanying drawings and specific embodiments.
The invention discloses a handheld precise depth soil sample collecting device, which comprises a sampling cylinder 1 and a central rod 2 which are connected through threads, wherein the bottom of the sampling cylinder 1 is conical, a length scale value 6 is arranged on the sampling cylinder 1 along the length direction of the sampling cylinder, and the numerical value of the length scale value 6 is gradually increased from the bottom end of the sampling cylinder 1 upwards.
Well core rod 2 is located the core rod line of sampler barrel 1, and well core rod 2 bottom is located the sampler barrel 1, and well core rod 2 top is provided with handle 3, and handle 3 is located the sampler barrel 1 outside.
The outer wall of the sampling cylinder 1 is provided with a plurality of sampling grooves 4, the sampling grooves 4 are positioned on a straight line parallel to the axis of the sampling cylinder 1 and are uniformly distributed, and the sampling grooves 4 are positioned on one side of the length scale value 6.
A closing plate 5 which can move along the length direction of the sampling tube 1 is arranged in the sampling tube 1, and the sampling groove 4 is closed when the closing plate 5 extends into the extreme position in the sampling tube 1. A hand push baffle 7 is fixed at the top end of the closing plate 5, and the hand push baffle 7 is positioned outside the sampling tube 1.
The use process of the handheld precise deep soil sample collecting device is as follows:
the closing plate 5 is inserted into the sampling cylinder 1 and reaches the limit depth in the sampling cylinder 1, and the soil sampling position and the target sampling depth are determined.
And (3) placing the top end of the bottom of the sampling cylinder 1 at a soil sampling position, keeping the central rod 2 still, rotating the sampling cylinder 1 to enable the sampling cylinder to go deep into the soil, observing the length scale value 6, and stopping rotating when the numerical value of the length scale value 6 reaches the target sampling depth.
The hand-push baffle 7 is tightly held to pull the closing plate 5 upwards until the bottom end of the closing plate 5 can be seen at the position above the soil and closest to the sampling groove 4 of the soil or the closing plate 5 is completely pulled out according to the sampling depth, the state of the closing plate 5 at the moment is kept for a period of time (3s-60s), the soil is made to enter the opened sampling groove 4, and then the closing plate 5 is pushed to reach the limit depth in the sampling cylinder 1.
The sampling tube 1 is taken out of the soil, the sampling tube 1 is horizontally placed, the sampling groove 4 is located at the highest position of the sampling tube 1, the sealing plate 5 is pulled outwards, the sampled soil is leaked, and the sampled soil is collected as required to perform subsequent soil analysis.
According to the mode, the handheld precise deep soil sample collecting device is simple in structure and convenient to use; the multiple sampling grooves can sample soil with multiple depths at one time; in the sampling process, the depth can be accurately sampled according to the sampling requirement; in addition, the sampling groove is closed before and after sampling, so that the sample is prevented from being mixed with other soil in depth when the sampling cylinder is moved, the collected sample is not polluted, and the important effect is played on the accurate analysis of the subsequent soil; the whole sampling process is convenient and accurate.
