Embodiment 1

[0021] as attached figure 1 with 2 Shown, a kind of small soil drill with soil sample collection and filling function, comprises soil drill and push-off device, and described soil drill comprises handle 1, outer connecting rod 2 and drill bit 5, and described push-off device includes push-off device Handle 6, inner connecting rod 3 and conical truncated push baffle plate 4. The outer connecting rod 2 is hollow and communicates. A sliding groove 8 and a fixing bayonet 9 are left on the outer wall of the outer connecting rod. The drill bit 5 includes a drill bit body and a cutter head 7, the cutter head is an ordinary cutter head, and the diameter of the cutting edge of the cutter head is equal to or less than 1 cm. The connection between the drill body and the cutter head 7 is a spiral type. The common cutter head is circular and has a blade for cutting soil.

Embodiment 2

[0023] as attached figure 1 , 2 , shown in 3, the difference with embodiment one is: in embodiment two, the length of outer connecting rod 2 is 50-100cm, and the cutter head is split type cutter head, is on the basis of common type cutter head, has blade Inside the cutter head on one side, there is a split cable 10 for dividing the soil sample in the soil drill, and the split cable passes through the center of the section of the cutter head 7.

Embodiment 3

[0025] as attached figure 1 , 2 , 4, the difference with Embodiment 1 is: in Embodiment 3, the cutter head is a split type cutter head, which is based on the ordinary cutter head, and inside the side cutter head with the blade, there are two The vertical splitting cable 10 used to split the soil sample in the soil drill is connected with a circular splitting ring 11 between the two splitting cables, and the center of the splitting ring coincides with the center of the section of the cutter head.

[0026] In the present invention, the small-sized soil drill with soil sample collection and filling functions of Embodiment 1 can be used to complete the collection and filling of soil samples, specifically: select the sampling plot according to the purpose of the experiment, and put the push handle 6 into place when taking soil. Insert the soil drill into the fixed bayonet 9. When sampling, press the soil drill handle 1 vertically, and the soil gradually enters the soil drill bit 5...

Abstract

The invention discloses a small-sized soil auger with functions of collecting and filling a soil sample. The small-sized soil auger comprises a soil auger body and a pushing and blocking device, wherein the soil auger body comprises a handle, an outer connecting rod and an auger bit; the pushing and blocking device comprises a pushing and blocking handle, an inner connecting rod and a circular-truncated-cone-shaped pushing and blocking plate. The small-sized soil auger disclosed by the invention has the advantages that the operation of the process of borrowing soil and filling soil is simple, the speed is high, the influence on the quality of the sample due to contact of other tools with the sample and long-time operation is avoided, the damage to the soil is also less; especially when the sample is collected in rain, the pollution possibility of rainwater to the soil sample is reduced, and the experimental error caused by manual filling is avoided; in addition, different cutter heads can be replaced for the auger bit part, so that soil sampling and soil borrowing are convenient, more cost is saved, the need for different experimental purposes is also convenient, and the working efficiency is improved.

Description

technical field [0001] The patent of the invention relates to a field sampling device for soil science, in particular to a small soil drill with the functions of collecting and filling soil samples. Background technique [0002] Stable hydrogen and oxygen isotope tracing is one of the most extensive and effective methods in hydrology and ecology research. In order to achieve research purposes such as clarifying the runoff mechanism of slopes and watersheds, plant water use strategies, and soil evaporation processes, it is necessary to measure the soil water isotope ratio with high precision, and the low-temperature vacuum distillation method is generally used for measurement. The pretreatment of this method requires collecting a certain amount of soil and putting it into a small sample glass bottle, and then putting it into a distillation glass tube for extraction. Since the standard requirements for isotope hydrology experimental research are extremely precise, the experim...
