Abstract

A three-leaf soil fetcher, including handles connected sequentially from top to bottom, an opening and closing mechanism, and a three-leaf soil fetching barrel. The three-leaf soil borrowing barrel is composed of three curved steel plates with an arc of 120 degrees to form a whole One of the arc-shaped steel plates is a fixed steel plate fixedly connected with the opening and closing mechanism, and the other two arc-shaped steel plates are movable steel plates that are movably connected with the opening and closing mechanism. Adopting the soil fetcher of the utility model can realize two modes of soil fetching and sampling, and can flexibly switch between the two modes, and is extremely convenient to use.

Description

Three-leaf soil fetcher

technical field

The utility model relates to a tool, in particular to a three-leaf soil fetcher.

Background technique

As the research of many disciplines involves field sampling, especially the collection of soil samples, including soil science, agronomy, ecology, environmental science and other disciplines, researchers have higher and higher requirements for soil sample collection. The soil fetcher is cylindrical and has no movable type. After the soil sample is taken, it is very difficult to push out the soil sample. Sometimes the soil sample will be deformed due to the thrust, and the soil layering cannot be well performed according to the test requirements. The main disadvantages are:

(1) The lower end of the soil extractor is a whole cylindrical steel plate, which is inactive. It takes a lot of effort to push the soil down, and when the soil is pushed hard, some soil samples will be deformed;

(2) Most soil fetchers do not have scales, so soils of different soil depths cannot be well collected according to requirements.

Utility model content

The purpose of this utility model is exactly in order to solve the problems referred to above, a kind of novel three leaf type soil fetching device is provided.

In order to achieve the above object, the utility model adopts the following technical solutions: a three-leaf soil fetching device, including handles connected sequentially from top to bottom, an opening and closing mechanism and a three-leaf soil borrowing cylinder, and the three-leaf soil borrowing cylinder consists of Three arc-shaped steel plates with a radian of 120 degrees are combined into a whole cylinder, one of which is a fixed steel plate fixedly connected to the opening and closing mechanism, and the other two arc-shaped steel plates are movable steel plates connected to the opening and closing mechanism. .

The opening and closing mechanism includes a steel cylinder and two sliding plates; the steel cylinder is provided with two vertical chutes, and the upper ends of the two sliding plates are respectively set in the two vertical chutes and can move up and down along the chutes. The lower end of the slide plate is connected with two movable steel plates to drive the movable steel plate to open and close; the handle is fixedly connected with the upper end of the steel cylinder; the upper end of the fixed steel plate is fixedly connected with the lower end of the steel cylinder, and the upper end of the two movable steel plates They are respectively connected with the lower end of the steel cylinder.

The inside and outside of the fixed steel plate are provided with scales.

Figure 1 is a schematic diagram of the overall structure of the utility model.

Detailed ways

Referring to Fig. 1, the three-leaf soil fetching device of the present utility model comprises a handle 1 connected in sequence from top to bottom, an opening and closing mechanism and a three-leaf soil fetching cylinder. The curved steel plates are combined into an integral cylinder, one of which is a fixed steel plate 7 fixedly connected with the opening and closing mechanism, and the other two curved steel plates are movable steel plates 4 and 5 which are movably connected with the opening and closing mechanism.

The opening and closing mechanism in the utility model includes a steel cylinder 2 and two slide plates 3; two vertical slide grooves are arranged on the steel cylinder, and the upper ends of the two slide plates are respectively set in the two vertical slide grooves and can be moved along the slide grooves. Moving up and down, the lower ends of the two slide plates are respectively connected with the two movable steel plates 4 and 5 to drive the movable steel plates to open and close; the above-mentioned handle 1 is fixedly connected with the upper end of the steel cylinder 2; , the upper ends of the two movable steel plates 4 and 5 are connected to the lower end of the steel cylinder 2 respectively.

All are provided with scale 6 inside and outside fixed steel plate 7.

The device has two modes of use: the mode of taking soil and the mode of taking samples. Soil taking mode: when the two sliding plates are pushed down, the two movable steel plates 4, 5 and the fixed steel plate 7 are combined to form a three-leaf soil taking cylinder, which can take soil samples of 0-20cm; sample taking mode: pull up When there are two sliding plates, the two movable steel plates are opened to expose the soil samples taken. Soil samples of different depths can be obtained according to the needs of the experiment.
