Description

Technical Field

[0001] The utility model relates to the technical field of soil sample collection, and in particular to a soil sampler capable of conveniently taking out clay soil. Background Art

[0002] For agricultural water, soil and agricultural environment experiments, soil samplers are one of the indispensable tools for scientific researchers. Soil can be divided into three categories according to the amount of sand content: sandy soil, loam and clay soil. Among them, clay soil has less sand content, fine particles, slow water infiltration, good water retention and poor ventilation. When the soil sampler takes soil with a small sand content or a high water content, that is, soil with high viscosity, it is difficult to remove the soil from the soil sampler part, and it is necessary to use a spoon-like tool to buckle it out from the gap of the soil sampler, which is time-consuming and laborious. The straight-cylinder soil sampler is equipped with a pusher round cake, but because the soil in the soil sampler is very viscous and basically a soil column tightly attached to the wall, it requires a lot of force to push it out, and sometimes it can't even be pushed out. It is necessary to use scissors, iron spoons and other tools to dig out part of the soil before pushing out the remaining soil, which is extremely inconvenient to use. Utility Model Content

[0005] The soil extractor is composed of more than two arc-shaped pieces arranged opposite to each other, the bottoms of the more than two arc-shaped pieces intersect to form a pointed bottom, and the side walls of the arc-shaped pieces are provided with blades.

[0006] The bulldozer is a hollow inverted cone composed of two semi-conical shells. The top of the semi-conical shell is arranged in multiple sliding grooves at the bottom of the push plate through multiple sliding blocks and can slide relatively. One end of the connecting rod is hinged to the bottom of the push rod, and the other end is hinged to the inner wall of the semi-conical shell.

[0007] A baffle plate II connected with a spring II is arranged in the slide groove II at the bottom of the push plate, and is used to cover the slide groove II after the semi-conical shell of the bulldozer is closed.

[0008] When the above device is used, first use both hands to hold the handle and place the soil sampler on the plot of land to be sampled, press down and rotate the handle with both hands to press down and rotate the soil sampler, and place the soil sampler in the corresponding soil layer. At this time, the soil sampler is filled with the required soil, and the sampling process is completed; lift the handle with both hands to lift the soil sampler out of the soil; then, hold the hollow rod I with one hand and hold the cross bars I and II with the other hand, and lift the cross bar II with four fingers while pressing the cross bar I, so that the hollow rod II and the push rod are pushed downward relative to the hollow rod I, and the push rod moves upward relative to the hollow rod II, and after compressing the spring between the internal limit blocks I and II of the hollow rod II, the two semi-conical shells of the bulldozer are unfolded, and the push plate and the two semi-conical shells completely push the soil in the soil sampler out of the two gaps of the soil sampler during the downward pressing of the cross bars I and II, release the push rod, the spring returns to its original position, and the two semi-conical shells of the bulldozer are closed into a hollow inverted cone.

[0009] Advantages and technical effects of the utility model:

The bottom end of the push rod 9 is hinged with the bulldozer 15 through two connecting rods 11. The bulldozer 15 is a hollow inverted cone composed of two semi-conical shells. A slider is fixed on the top of the semi-conical shell, and a baffle Ⅰ12 is fixed on the inner wall. The top of the semi-conical shell is arranged in the slide groove Ⅱ at the bottom of the push plate through the slider and can slide. One end of the connecting rod 11 is hinged with the bottom of the push rod 9, and the other end is hinged with the inner wall of the semi-conical shell and is located below the baffle Ⅰ12. Four limit blocks Ⅱ14 are arranged on the inner wall of the hollow rod Ⅱ8, which are arranged opposite to each other. A limit block Ⅰ13 is fixed on the push rod 9, and a spring Ⅰ2 is connected between the limit block Ⅱ14 and the limit block Ⅰ13. The limit block Ⅰ cooperates with the limit block Ⅱ to limit the up and down moving distance of the push rod 9.

[0020] Example 2: Figure 4 , 6 As shown, the structure of the device in this embodiment is the same as that in embodiment 1, the difference is that a baffle II19 connected to a spring II18 is provided in the slide groove II at the bottom of the push plate 10, which is used to cover the slide groove II after the semi-conical shell of the bulldozer is closed.
