Sediment collector
Technical Field
The utility model relates to a sampling equipment especially relates to a sediment collector, belongs to environmental protection analysis technical field.
Background
In natural waters, the interaction process of pollutants between water and sediment is continuously carried out, and the process is more active particularly in shallow sediment. Therefore, in water environment monitoring, treatment and protection research, the interaction effect between the water body and the shallow sediment is an important research content, and a large amount of shallow sediment needs to be collected for in-situ layered analysis.
Also there are some simple and easy mud sampler now, and the mud sampler front end is front end open-ended tubulose sampling barrel, rear end and is the handle, connects through the connecting rod between handle and the sampling barrel, samples the sampling barrel to pond, river course deposit, but this type of mud sampler only is fit for gathering comparatively loose soft bed mud, just can not get up in comparatively hard bed mud of substrate, still often damages because mechanical strength is not enough mud sampler, and then influences the use.
SUMMERY OF THE UTILITY MODEL
The utility model discloses not enough to present simple and easy mud sampler exist provides a mechanical strength height, can pierce the sediment collector in the hard sediment.
The utility model provides an above-mentioned technical problem's technical scheme as follows:
The bottom mud collector comprises a collecting barrel, a cutting head, an extrusion plate, a handle and an extension rod, wherein the barrel wall of the collecting barrel is composed of a glass inner layer and a steel outer layer, the collecting barrel is movably connected with the cutting head below the collecting barrel, the cutting head is hollow and is in an inverted conical shape, a cut port which is obliquely cut is formed in the bottom of the cutting head, the extrusion plate which is matched with the size of the inner wall of the collecting barrel is arranged in the collecting barrel, the extrusion plate is connected with the handle above the extrusion plate through the connection rod, and the extension rod is arranged on the outer wall of the middle upper portion of the collecting barrel.
The utility model has the advantages that:
1. The steel collection cylinder outer wall can prevent direct stress of the glass cylinder in the collection process, and then damage is caused, and the cleanliness of ground mud can be kept by the glass collection cylinder inner wall, so that pollution to bottom mud caused by the steel pipe is prevented.
2. The cutting head at the bottom is conical, so that the cutting head can penetrate into hard bottom mud in the downward mud taking process, and the bottom mud can enter a glass cylinder in the mud sampler more easily;
3. The extension rod has the effect that when water is deep, the collector can be extended into the bottom of the water for collection, and the use is convenient. On the basis of the technical scheme, the utility model discloses can also do following improvement. Further, the extension rod is L-shaped. The beneficial effect of adopting above-mentioned further technical scheme is that, the operation is changeed in the collection process, and is more convenient when taking.

In the figure, 1-collection cartridge; 2-a cutting head; 3-cutting the opening; 4-extruding a plate; 5-a connecting rod; 6-a handle; 7-extension rod.
Detailed Description
the principles and features of the present invention are described below in conjunction with examples, which are set forth only to illustrate the present invention and are not intended to limit the scope of the present invention.
as shown in figure 1, a sediment collector, including a collection section of thick bamboo 1, the cutting head 2, the stripper plate 4, handle 6 and extension rod 7, the section of thick bamboo wall of a collection section of thick bamboo comprises glass inlayer and steel skin, a collection section of thick bamboo and the cutting head swing joint of its below, cutting head cavity just is the circular cone of inversion, the bottom of cutting head is equipped with the cutting cut 3 of beveling, be equipped with the stripper plate with the inner wall size looks adaptation of a collection section of thick bamboo in the collection section of thick bamboo, the stripper plate is connected rather than the handle of top through connecting rod 5, be fixed with the extension rod on the outer wall of upper portion in the collection section of thick bamboo, the extension rod.
The utility model discloses sediment collector's use as follows:
1. Inserting a collector into the sludge, and enabling the bottom sludge to enter a collecting cylinder through a cutting head;
2. The bottom sediment collector is lifted out by lifting and pulling the extension rod;
3. The cutting head is detached, the squeezing handle is squeezed, the squeezing block plate at the bottom of the handle is moved downwards by pressure, and bottom mud is squeezed out of the collecting cylinder, so that the bottom mud is analyzed and detected.
The above description is only for the preferred embodiment of the present invention, and is not intended to limit the present invention, and any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present invention should be included within the protection scope of the present invention.
