Description

Technical Field

[0001] The invention belongs to the field of sampling mechanisms, and in particular relates to a sampling mechanism for green garden construction. Background Art

[0002] Soil refers to the loose material layer covering the earth's land surface, with fertility characteristics, and capable of growing green plants. Soil is composed of minerals formed by weathering of rocks, plants and animals, organic matter produced by the decomposition of microbial residues, soil organisms (solid phase matter), water (liquid phase matter), air (gas phase matter), humus, etc. Soil is an important ecological factor for both plants and soil animals. The root system of plants has a large contact surface with the soil, and there is frequent material exchange between plants and soil, which has a strong influence on each other. Therefore, by controlling soil factors, the growth and yield of plants can be affected. The physical environment of the soil first affects the water and air supply of crops, and also directly affects the supply and conservation of nutrients. With the serious pollution of the ecological environment, it is necessary for people to detect the soil to ensure the survival rate of plants. When detecting the soil, it is usually necessary to sample the soil first, and then test and analyze the sampled soil. At present, the most common soil sampling device is to insert the sampling tube deep into the soil to obtain soil samples, but it is not easy to remove the soil stored in the sampling tube in this way. And after taking out, the sample needs to be put into the sample box by hand, which will cause pollution to the hands. Therefore, it is necessary to propose a sampling mechanism for green garden construction. Summary of the invention

[0003] The purpose of the present invention is to solve the problems in the background technology and provide a sampling mechanism for green garden construction.

[0004] The above technical objectives of the present invention are achieved through the following technical solutions: A sampling mechanism for green garden construction includes an insertion barrel, a material collection barrel, a material storage barrel, a soil separation structure, a pop-up structure, and a cover plate.

The soil in the storage tube is separated from the soil in the soil by the soil separation structure, and then the cover plate is opened, and the storage tube is ejected by the pop-up structure. The storage tube is then taken out and used as a sample box. There is no need to touch the sample with hands, and there is no need to transfer the sample to the sample box. At the same time, the soil is also easy to take out from the sampler, which makes the operation more convenient and convenient for manual sampling.

[0006] Preferably, the soil cutting structure includes a rotating bearing, a rotating rod, a cutting rod, a pulling rod, and a swinging rod. The outer ring side wall of the rotating bearing is fixed on the inner side wall of the insertion tube. The rotating rod is arranged on the inner ring of the rotating bearing.

The pulling rod is fixed at the starting end of the cutting rod and extends upward along the axial direction of the insertion tube to the top of the insertion tube. The cutting rod is tilted downward in the initial state to facilitate the sampler to be inserted into the soil. The angle B is 120°~130°, so that after rotation, the cutting rod can be tilted, thereby separating the soil in the soil from the soil in the sampler.

[0007] The present invention causes the swing arm to rotate with the rotary bearing as the center through the upward and downward reciprocating motion of the pull rod, thereby driving the cutting rod to move in the direction close to and away from the material taking barrel, thereby separating the soil in the material storage barrel from the soil, and completing the sampling work.

[0008] Preferably, there are more than three soil separation structures evenly distributed along the circumferential direction of the insertion cylinder, an upper limit fixing ring and a lower limit fixing ring are provided between the insertion cylinder and the material collection cylinder, the pull rod passes through the upper limit fixing ring and the lower limit fixing ring, and a limit block is provided at the part of the pull rod located between the upper limit fixing ring and the lower limit fixing ring.

[0012] The present invention allows the material storage barrel to abut against the second retaining ring, and then covers the lid, so that the pop-up spring is squeezed, so that the material storage barrel is installed in the material taking barrel, and then opens the cover plate, and the material storage barrel is subjected to the elastic force of the pop-up spring and pops out, so that it is easy to take out.

[0013] The present invention can cooperate with the pop-up spring to deform through the silicone layer, and can also prevent mud from entering the pop-up spring to affect the action of the spring.

[0014] Preferably, an L-shaped limiting groove is provided on the material taking barrel, and a sliding block cooperating with the L-shaped limiting groove is provided on the cover plate.

[0015] The present invention enables the slide block to slide into the L-shaped limiting groove and then rotate, so that the cover plate presses the material storage barrel.

The tightening mechanism is arranged on the pressing block.

[0019] The present invention realizes the extension and retraction of the connecting rod by moving the inner tube. After the height is determined, the tightening mechanism is moved in the direction of the groove, so that the pressing block is pressed in the groove, thereby fixing the inner tube and realizing convenient and quick adjustment of the height of the connecting rod. Therefore, the height can be freely adjusted according to the height of the human body, which is convenient for exerting force and more user-friendly.

[0021] When the present invention needs to be fixed, the slide block is pressed by a button to shrink the compression spring, and the swing arm slides to the top of the automatic guide slot, so that the tightening rod at the bottom moves downward, thereby driving the pressing block to be pressed into the groove. When the height adjustment is not needed, the button is pressed again, and the swing arm moves to the bottom of the automatic guide slot, so that the tightening rod is retracted into the sliding slot, driving the pressing block to leave the groove, so that the inner tube can move in the outer tube.

[0022] Preferably, a cutting rod protection tube is formed at the bottom of the insertion tube, the cutting rod protection tube is conical, and the end of the cutting rod is located on the inner wall of the cutting rod protection tube. The cutting rod is protected by the conical design to prevent the cutting rod from being directly stressed during the downward pressing process, thereby extending the service life.

[0023] In summary, the beneficial effects of the present invention are: 1. The present invention inserts the sampling mechanism into the soil through the insertion tube, and the soil enters the storage tube. The soil in the storage tube is separated from the soil in the soil through the soil separation structure.
