Description

River bottom silt sampling device

Technical Field

The utility model relates to the field of sludge sampling, in particular to a river bottom sludge sampling device.

Background

The method is very difficult to detect the river bottom sludge and collect, because the river bottom sludge has different depths and different softness and hardness, the river bottom sludge is usually collected by manually holding the scoops to the river bottom, the method is very backward and very difficult, the quality of the collected sludge is not high, and when the sludge is thinner, the sludge can flow out from the scoops in the process of lifting the sludge from water, so that incorrect data of sludge detection are caused, and for the sludge with harder texture, the sludge is diluted in the lifting process without being sealed, so that incorrect data of sludge detection are also caused.

Disclosure of Invention

In order to solve the technical problems, the utility model adopts the following technical scheme: the utility model provides a river bottom silt sampling device, includes the dead lever, and the dead lever lower extreme is equipped with cylinder structure sampling barrel, and sampling barrel lower extreme is equipped with the opening, and sampling barrel inside is equipped with the screw axis, and the screw axis upper end is connected with the dwang, and the dwang passes the dead lever and keeps away from the dead lever top, and sampling barrel one side is equipped with the discharging pipe, and discharging pipe lower extreme opening is equipped with the sample bottle.

In the preferred scheme, the dwang top is connected with rotating device, and rotating device includes motor or rolling disc.

In the preferred embodiment, the tapping pipe is arranged obliquely downwards.

In the preferred scheme, the lower end opening of the discharging pipe is in threaded connection or clamping connection with the sampling bottle.

In the preferred scheme, the dead lever upper end is equipped with the handle, and the handle surface is equipped with friction portion.

In the preferred scheme, the screw shaft external diameter cooperates with the sampling barrel internal diameter, and the screw shaft lower extreme is equipped with the drill bit of protrusion sampling barrel lower extreme.

The utility model provides a river bottom sludge sampling device, wherein a sampling barrel at the end part of a fixed rod is inserted into river bottom sludge, a rotating rod is rotated, the rotating rod drives a screw shaft in the sampling barrel, and the screw shaft conveys the river bottom sludge to the top of the sampling barrel and conveys the river bottom sludge from a discharging pipe to the inside of a sampling bottle, so that the purpose of collecting the sludge is achieved; the utility model has simple structure and strong practicability, can effectively collect river bottom sludge according to different textures, can accurately collect data of the river bottom sludge, reduces the difficulty of collecting data, and is convenient for daily work.

Drawings

The utility model is further illustrated by the following examples in conjunction with the accompanying drawings:

fig. 1 is a front view structural diagram of the present utility model.

In the figure: a rotating disc 1; a rotating lever 2; a fixed rod 3; a handle 4; a sampling barrel 5; a screw shaft 6; a drill bit 7; a discharge pipe 8; a sampling bottle 9.

Detailed Description

As shown in FIG. 1, a river bottom silt sampling device, including dead lever 3, the dead lever 3 lower extreme is equipped with cylinder structure sampling barrel 5, and sampling barrel 5 lower extreme is equipped with the opening, and sampling barrel 5 is inside to be equipped with screw axis 6, and screw axis 6 upper end is connected with dwang 2, and dwang 2 passes dead lever 3 and keeps away from dead lever 3 top, and sampling barrel 5 one side is equipped with discharging pipe 8, and discharging pipe 8 lower extreme opening is equipped with sample bottle 9. The sampling bucket 5 of dead lever 3 tip inserts in the river bottom silt, rotates dwang 2, and dwang 2 drives the inside screw axis 6 of sampling bucket 5, and screw axis 6 carries river bottom silt to sampling bucket 5 top to inside the sample bottle 9 is carried from discharging pipe 8, so that reaches the purpose of gathering silt.

In a preferred embodiment, the top of the rotating rod 2 is connected with a rotating device comprising a motor or rotating disc 1. This application adopts manual swivelling levers 2, in complicated topography, can adopt motor drive swivelling levers 2 to take a sample.

In a preferred embodiment, the tapping pipe 8 is arranged obliquely downwards. The inclined downward mode is shown in fig. 1, and the inclined downward mode can smoothly convey the sludge into the sampling bottle 9.

In the preferred scheme, the lower end opening of the discharging pipe 8 is in threaded connection or clamping connection with the sampling bottle 9. The scheme adopts a threaded connection mode to install.

In the preferred scheme, the upper end of dead lever 3 is equipped with handle 4, and handle 4 surface is equipped with friction portion. The handle 4 is convenient for the user to hold.

In the preferred scheme, the external diameter of screw shaft 6 cooperates with the internal diameter of sample bucket 5, and the drill bit 7 of protruding sample bucket 5 lower extreme is equipped with to screw shaft 6 lower extreme. The drill bit 7 can better take out the hard sludge at the river bottom.

The above embodiments are only preferred embodiments of the present utility model, and should not be construed as limiting the present utility model, and the scope of the present utility model should be defined by the claims, including the equivalents of the technical features in the claims. I.e., equivalent replacement modifications within the scope of this utility model are also within the scope of the utility model.
