Description

A kind of hammer type root drill

technical field

The utility model relates to the technical field of plant root system sampling, in particular to a hammering type root drill.

Background technique

Root system research is an important part of field experiments. At present, root drilling method is generally used for investigation and sampling in scientific research experiments. Root auger sampling includes two processes, the first process is to drill root samples from the field into the drill barrel, and the second process is to remove the root samples from the drill barrel.

Utilize the root drill that manpower drives at present, in the first process, the method that usually adopts is: manpower rotates the drill barrel to make the drill barrel drill into the soil layer. This method is less efficient, and when the drill pipe drills into a deeper soil layer, it is difficult to continue screwing in.

And in the second process, the method that usually adopts is: manpower knocks drill barrel with rubber hammer, makes the sample soil that contains root sample in the drill barrel gradually loosen, and after loosening to a certain degree, sample soil discharges drill barrel gradually. This method is not only inefficient and laborious, but also damages the root sample.

Of course, there are also non-human-driven root drills, such as gasoline-powered root drills. Although this type of root drill does not have the above-mentioned drawbacks, it is usually larger in size, heavier in quality, inconvenient to move in the field, and expensive, so it is not as widely used as a human-driven root drill.
