technical field

The utility model relates to the technical field of soil collection, in particular to a soil fetcher.

Background technique

In recent years, my country's soil pollution has been serious, especially the heavy metal pollution of large-scale farmland in my country. The early stage of soil remediation requires a large number of soil sample tests, and the use of soil samplers is frequently used in the sampling process. However, the soil samplers currently on the market have some problems in actual sampling. For example, in the case of flooded farmland or the bottom of the cultivated layer with a lot of sand, when the general sampler is inserted into the ground and then lifted, the soil sample will be removed from the ground. The sampling cylinder falls or flows out, resulting in a small amount of one-time sampling, insufficient representativeness, and a decrease in sampling efficiency. Therefore, it is necessary to propose a new type of soil sampler, which can collect dry field soil and paddy field soil, and can keep the soil sample from falling or flowing out during the paddy field sampling process.

Moreover, the existing soil fetcher is usually a T-shaped structure, which is inconvenient to carry. When sampling soil, the analysis is not precise enough to sample specific depths of soil.

Detailed ways

In order to make the purpose, technical solution and advantages of the utility model clearer, the utility model will be further described in detail below in conjunction with the accompanying drawings.

Referring to Fig. 1, 2 and 3, the utility model provides a kind of earth taker, is used for soil collection, comprises and is used for storing the soil earth taking cylinder 2 of soil, leak-proof part 3 and handle 2, and the middle place of described handle 2 is provided with Sealing cover 4, described sealing cover 4 is threadedly connected with the upper end of described soil-borrowing cylinder 2, to seal the upper end of described soil-borrowing cylinder 2, and the lower end of described soil-borrowing cylinder 2 is provided with draw-in groove 24, and described leak-proof The component 3 is connected to the soil-absorbing cylinder 2 through the clamping groove 24, and soil can enter the soil-absorbing cylinder 2 from the leak-proof component 3;

Wherein, the leak-proof component 3 includes a barrier plate arranged in the leak-proof component 3, and the barrier plate is hingedly connected with the leak-proof component 3 to prevent the soil in the soil borrowing cylinder 2 from the The leak-proof part 3 leaks out in reverse;

The side wall of the soil sampling cylinder 2 is provided with a strip hole 21 for soil sampling, and the handle 1 is provided with a tool storage chamber 12 for storing a sampling knife, and the sampling knife 12 can be inserted into the strip hole 21 , to quickly obtain soil samples.

Specifically, the slot 24 is provided with a notch 23 for installation and connection with the leak-proof component 3, and the leak-proof component 3 is provided with a protrusion corresponding to the notch 23, and the user only needs to place the The protrusion 32 of the leak-proof part 3 is inserted into the gap 23, and after the protrusion 32 enters the clamping groove 24, the leak-proof part 3 can be screwed to complete the removal of the leak-proof part 3 The connection of soil cylinder 2.

The barrier plate includes several baffle assemblies 31, the rotation range of the baffle assembly 31 is 0-90°, when the baffle assembly 31 turns to a horizontal state, the lower opening of the soil borrowing cylinder 2 is closed . Therefore, when the soil in the soil-borrowing cylinder 2 leaks out, the baffle plate assembly 31 will be pushed to rotate downward, and finally all the baffle plate assemblies 31 will be turned to a horizontal state to close the lower opening of the soil-borrowing cylinder 2, thereby Avoid soil leakage in the soil borrowing barrel 2 . Preferably, there are two baffle assemblies 31 and they are semicircular.

Therefore, soil sampling can be carried out directly without installing the leak-proof component 3 when collecting soil in dry fields. When encountering paddy field soil or soil with more sand in the bottom of the plow layer, the leak-proof component 3 can be quickly installed and then sampled.

In order to enable the utility model to collect samples of a specific soil depth, the side wall of the soil-taking cylinder is engraved with a scale 22 corresponding to the length of the strip hole 21 to judge the sampling depth of the soil. The length of the strip-shaped hole 21 is 1/2-3/4 of the length of the soil borrowing cylinder, and the distance from the lower end of the strip-shaped hole 21 to the leak-proof component 3 is not less than 15cm.

It should be noted that when the utility model is inserted into the soil, the closer it is to the leak-proof component 3, the greater the squeezing force on the soil in the soil borrowing cylinder 2 will be, which will easily cause the soil to leak out from the strip hole.
