Description

A portable columnar soil sampling device

technical field

The utility model belongs to the technical field of soil experiment equipment, in particular to a portable columnar soil sampling device.

Background technique

In soil research work, soil collection is a very common method of soil collection, especially when it is necessary to study the characteristics of different soil layers, it is necessary to collect soil at different depths in the same geographical feature at the same time.

At present, columnar soil collectors are usually used to collect soil at different depths at the same time. The soil extraction method is to manually squeeze and rotate the collector, and insert the collector under the surface for soil retrieval. Such a sampling method requires a lot of physical effort and time, and only one set of samples can be taken at a time, so the sampling efficiency is low.

Utility model content

The technical problem to be solved by the utility model is to provide a simple and easy-to-operate structure.

The utility model solves the problems of the technologies described above through the following technical solutions:

A portable columnar soil sampling device, comprising at least two sampling pipes, at least two first connecting rods, a push rod, an annular mud sampling handle and a motor, the output shaft of the motor is connected to the upper end of the push rod, and the sampling Pipes are evenly arranged around the pusher rods, and the sampling pipes are respectively fixedly connected to the pusher rods through one of the first connecting rods. The sampling pipes are all equipped with pusher rods, and the lower ends of the pusher rods are each A mud pushing piece is connected, and the upper ends of the mud pushing rods are connected to the ring-shaped mud picking handle.

Preferably, the lower end of the push rod is provided with an inverted conical drill bit.

Preferably, the thickness of the lower edge of the sampling tube gradually decreases toward the end.

Preferably, the edge of the lower end of the sampling tube is serrated.

Preferably, scale lines are provided on the push rod.

Preferably, a motor switch is provided near the upper end of the push rod.

The portable columnar soil sampling device provided by the utility model has a simple structure and is easy to operate. Sampling at the same time in the cylinder can improve the sampling efficiency.

detailed description

In order to enable those skilled in the art to better understand that the technical solution of the utility model can be implemented, the utility model will be further described below in conjunction with the accompanying drawings and specific examples, but the examples given are not intended to limit the utility model.

The utility model provides a portable columnar soil sampling device, specifically as shown in Figure 1 and Figure 2, comprising at least two sampling tubes 5, at least two first connecting rods 10, a push rod 7, an annular mud-collecting handle 1 and motor9.

In the embodiment, the number of the sampling tube 5 and the first connecting rod 10 are both 3, and can also be 4, 5 and so on. The output shaft of the motor 9 is connected to the upper end of the push rod 7, and the sampling tube 5 is evenly arranged around the push rod 7. The mud rod 2 is connected with the mud pushing piece 4 at the lower end of the mud pushing rod 2, and the mud pushing rod 2 upper ends are connected with the annular mud picking handle 1. The motor 9 drives the propulsion rod 7 to move downward, and then drives the sampling cylinder 5 to collect soil samples, saving manpower and time, and setting three sampling cylinders 5 to sample simultaneously can improve the sampling efficiency.

In this embodiment, in order to reduce resistance, an inverted conical drill bit 6 is provided at the lower end of the push rod 7, and the thickness of the lower end edge of the sampling tube 5 gradually decreases in the direction close to the end, which is in the shape of a knife edge. The lower edge is serrated.

In order to quickly and accurately read the depth of the collected soil samples, maintain the complete structure of the soil, and facilitate the precise stratification of the soil samples, a scale line 3 is also provided on the push rod 7, which is convenient for researchers to observe.

Simultaneously, in order to control the motor conveniently, a motor switch 8 is set near the upper end of the propulsion rod 7 .

As mentioned above, the above embodiments are only used to illustrate the technical solutions of the present utility model, rather than to limit it, the protection scope of the present utility model is not limited thereto, any skilled person familiar with the technical field is within the technical scope disclosed by the utility model Within the scope of the invention, simple changes or equivalent replacements of technical solutions that can be clearly obtained all belong to the protection scope of the present utility model.
