Embodiment Construction

[0009] Below in conjunction with accompanying drawing, the present invention will be further described:

[0010] A soil sampling device is composed of an outer cylinder 1 , a piston-type inner cylinder 2 , a handle 3 , a pedal 4 and an inner cylinder cover 8 . The outer cylinder (1) is a hollow cylinder, which is cut at an inclination angle of 30° to 75° at one end to form a shovel port 5, and an oblong perspective window 6 is opened 3 to 5 cm away from the shovel port 5 A pair of pedals 4 are fixed at a distance of 30-60 cm from the shovel port 5, and a pair of handles 3 are installed at a distance of 5-10 cm from the top of the outer cylinder 1. The piston-type inner cylinder 2 is a closed cylinder with an outer diameter of slightly Smaller than the inner diameter of the outer cylinder 1, the piston-type inner cylinder 2 can perform piston movement in the outer cylinder 1, and a pie-shaped inner cylinder cover 8 is placed at one end of the piston-type inner cylinder 2, and t...

Description

Technical field: [0001] The invention relates to a sampling device, in particular to a sampling device for maintaining the original order of soil layers. Background technique: [0002] In scientific experiments, especially when studying soil, it is necessary to use soil samples, and it is often required to obtain soil samples that can maintain the original order of the soil layer. Nowadays, shovels, hoes or punches are generally used to obtain soil samples. It is difficult to maintain the original order of soil layers in soil samples. Invention content: [0003] The object of the present invention is to provide a soil sampling device. The device can be conveniently inserted into the soil to obtain soil samples, and the soil samples can be kept in the original order of the soil layers. [0004] In order to achieve the above object, the present invention adopts the following technical solutions: the soil sampling device is composed of an outer cylinder, a piston-type inner...
