Description

Technical Field

[0001] The utility model relates to the field of bottom mud samplers, in particular to a weeding type bottom mud sampler. Background Art

[0002] Due to the discharge of industrial and domestic sewage, river ecological problems have been difficult to control. In recent years, with the reduction of sewage discharge, the quality of river water has been improved to a certain extent, but the riverbed sediment pollution is still relatively serious. The polluted sediment will cause long-term pollution to the river, so it is urgent to sample and monitor the riverbed sediment in the river.

[0003] On the other hand, riverbed sediment is usually a mixture of clay, silt, organic matter and various minerals, which is deposited at the bottom of the water body after a long period of physical, chemical and biological effects and water transport. Sediment sampling refers to sampling a mixture of underground organic and inorganic debris and soil. By analyzing the particle size and distribution of pollutants in the sediment, it provides a scientific basis for disciplines such as hydrogeology, environmental protection and ecological protection.

[0004] Grab bucket sediment samplers are generally used for sediment collection, but the current samplers do not have a weeding function. Therefore, when collecting sediment, if there are weeds or other substances in the riverbed, the sediment cannot be smoothly taken up, which causes great trouble in collecting the sediment. Utility Model Content

[0005] The utility model aims to provide a weeding type bottom mud sampler, which solves the problem that the sampler in the prior art does not have a weeding function, so when taking bottom mud, when there are weeds or other substances in the riverbed, the bottom mud cannot be taken up smoothly.

[0007] The fixing sleeve has an interior provided with an installation groove, and the installation groove corresponds to the first connecting rod and the second connecting rod.

[0008] As a further description of the above technical solution: sliding blocks are fixedly connected to the two ends of the inner side of the installation groove, and sliding grooves are provided at both ends of the first connecting rod and the second connecting rod.

[0009] As a further description of the above technical solution: the sliding block is slidably connected to the inside of the sliding groove, and a plurality of first screw holes are opened inside the sliding groove.

[0010] As a further description of the above technical solution: both ends of the fixing sleeve are threadedly connected with second screw holes, and the internal threads of the first screw hole and the second screw hole are threadedly connected with positioning bolts.

[0011] As a further description of the above technical solution: a handle is fixedly connected to the connecting end of the first connecting rod and the second connecting rod.

[0012] As a further description of the above technical solution: the upper ends of the first connecting rod and the second connecting rod are rotatably connected with a rotating member, and one end of the rotating member is fixedly connected with a cylinder.

[0013] The utility model has the following beneficial effects:

[0014] 1. Compared with the prior art, the weeding type sediment sampler can install the fixing sleeve and the sediment grab bucket at the lower end of the device by setting the installation groove, the slide groove, the slider, the screw hole and the positioning bolt, so as to improve the convenience and practicality of the device. By installing the weeding nail at the lower end of the sediment grab bucket, the angle of the two connecting rods can be changed to remove the weeds on the riverbed, and then the sediment sampling work can be carried out, thereby improving the sampling efficiency of the whole sampler;

[0015] 2. Compared with the prior art, the weeding-type sediment sampler can realize the automatic rotation sampling operation of the device by setting a cylinder, a rotating sleeve and a handle, thereby improving the practicability of the device.
