Problems solved by technology

For the layered collection of sediment samples at different water depths, there is not yet a stereotyped product with a wide range of applications and stable functions in China. At present, some sediment collection devices used in China often mix the sediments of various layers together, which cannot reach the level of separation. The purpose of layering; there are also some sediment collection devices that require manual layering, which is not only inefficient but also wasteful

Embodiment Construction

[0019] The implementation of the present invention will be described in further detail below with reference to the accompanying drawings. The following embodiments are only descriptive and not restrictive, and the protection scope of the present invention cannot be limited by this.

[0020] An automatic layered mud mining device, such as figure 1 Or as shown in 2, it includes a sampling base plate 2, a T-shaped device handle 1 is fixed on the upper surface of the sampling base plate, and a set of symmetrical spiral sleeve bases 3 are fixed on the lower surface of the sampling base plate, A hollow dredging pipe 4 is screwed under the base of each spiral sleeve, and each dredging pipe is composed of a plurality of dredging pipe units 5 which are screwed end to end. Two semicircular anti-backflow baffles 6 are installed inside the bottom end of the unit.

[0021] In the specific implementation of the present invention, such as figure 2 As shown, the size of the overall disc formed b...

Abstract

The invention relates to an automatic layered sludge collection device which comprises a sampling base plate, wherein a T-shaped device handle is fixedly arranged on the upper surface of the sampling base plate; a group of centrosymmetric spiral sleeve bases are fixedly arranged on the lower surface of the sampling base plate; hollow sludge collection pipes are spirally connected below the spiral sleeve bases; each sludge collection pipe consists of a plurality of sludge collection pipe units which are spirally connected with one another end to end; two semicircular backflow-prevention stop sheet are arranged in the bottom end of each sludge collection pipe unit. The automatic layered sludge collection device is simple in structure and convenient to operate and can simultaneously collect a plurality of samples and store the original thicknesses and the layered structures of deposits; the sampling base plate and the sludge collection pipes can be freely mounted and dismounted; the automatic layered sludge collection device is convenient and easy to use and can be replaced and cleaned quickly; the production cost is saved.

Description

Technical field [0001] The invention belongs to the technical field of mud mining, and specifically relates to an automatic layered mud mining device. Background technique [0002] At present, in the research of marine ecology, freshwater ecology and other aquatic ecosystems, the collection of water sediment samples is an important part of the investigation of the bottom quality of water bodies, and it is also an important basis for sediment analysis and research. Therefore, some equipment is needed to conduct sampling surveys specifically for the sediment environment. For the layered collection of sediment samples from different water depths, there is no domestic product with a wide range of applications and stable functions. At present, some sediment collection devices used in China often mix the sediments of various layers together, which cannot achieve the separation. The purpose of layering; there are also some sediment collection devices that require manual layering, which...
