Description

Technical Field

[0001] The utility model relates to an electric sampling mechanism, belonging to the fields of agricultural soil sampling, soil science research and production environment monitoring. Background Art

[0002] Sampling the dryland soil of fruit orchards, economic forests, etc. is the basic work for conducting research on soil fertility evolution, soil resource evaluation, soil ecological environment, soil improvement, and reasonable soil fertilization. It is also an important means for soil environmental quality monitoring and environmental quality evaluation in the production environment. However, due to the solid and hard soil of drylands such as fruit orchards and economic forests, when taking such soil, the traditional insertion or manual soil sampler is very laborious and time-consuming to enter the deep soil, and there is a disadvantage that it is not easy to take out after entering, and sometimes even the sampling cannot be completed due to excessive energy consumption; there are also a small number of soil samplers that use gasoline engines, plug-in motors, etc. to drive soil sampling, but the existing gasoline engine-driven, plug-in motor-driven soil samplers are relatively heavy, and sampling, transportation, and operation are very laborious, and the sampling operation is too inconvenient. Therefore, it is urgent to provide an electric sampling mechanism suitable for sampling hard soils such as orchards to solve the above problems. Utility Model Content

[0003] The utility model aims to provide an electric sampling mechanism, which can effectively reduce the labor intensity of workers, conveniently and quickly take samples from hard soil layers, save time and manpower, and improve soil sampling efficiency.

[0004] In order to achieve the above-mentioned purpose, the technical solution adopted by the utility model is: the electric sampling mechanism includes an electric drive device, an adapter assembly, and a sampling assembly; the electric drive device includes a forward and reverse motor, a forward and reverse control unit, a rotating rod and a connecting piece, and the forward and reverse control unit controls the forward and reverse motor to drive the rotating rod to rotate; the adapter assembly includes a connecting rod and a fastener, and the connecting piece is connected and fixed to the connecting rod; the sampling assembly includes a sampling tube and a sampling drill bit, and the sampling tube is connected and fixed to the connecting rod through the fastener, and the sampling tube and the sampling drill bit are both detachable.

[0005] According to the embodiments of the present invention, the present invention can be further optimized. The following is the technical solution formed after optimization:

[0006] In one preferred embodiment, the electric drive device further comprises a speed regulator, which can adjust the rotation speed of the forward and reverse motor. The electric drive device can be a universal rechargeable electric drill with adjustable speed.

[0007] In one of the preferred embodiments, the fastener is a fastening nut, the lower end of the connecting rod is fixed to one end of the fastening nut, and the connecting rod is threadedly connected to the sampling tube and is connected and fixed by the fastening nut.

The sampling tubes can be selected to have an outer diameter of 30 mm, an inner diameter of 25 mm, and a single length of 200 mm.

[0009] In one preferred embodiment, the upper end of the connecting rod is a concave cylindrical structure. When connected to the electric drive device, the upper end of the connecting rod adopts a concave cylindrical structure, which is tighter than a smooth cylindrical structure, and when the electric drive device drives the sampling assembly to operate at a high speed, the upper end of the connecting rod adopts a concave cylindrical structure to avoid the sampling mechanism from slipping, vibrating violently, etc.

According to the depth of the sampled soil, multiple sampling tubes 12 can be connected. One end of the sampling tube 12 is a threaded external thread port 401 and the other end is a threaded internal thread port 402. One end of the sampling drill bit 13 is a threaded external thread port 501 and the other end is a conical drill tooth structure 502 for gripping the ground.

[0036] Step 5: Turn on the clockwise rotation button of the forward and reverse rotation button 6 and the power switch 5, and let the motor drive the rotating rod 14 to push the sampling assembly 3 to rotate and move downward into the deep soil, so that the soil sample to be taken enters the sampling tube 12.
