Description

Hard ground sampler
technical field:
The utility model relates to a kind of environmental monitoring utility appliance, is specifically related to a kind of hard ground sampler.
background technology:
Soil sampling comprises laying and the sampling technique of sampling.Adopt section soil sample, should observe after record terminates at section and carry out.First section should be rebuild before sampling, cleaning, the surface dust on most top layer of pruning, and then press level and successively sample from center typical parts from top to bottom.
Existing soil sampler has numerous species.Gather farmland or wasteland topsoil sample, available small-sized spades.The general physical property of research soil, as the soil weight, porosity and water retention characteristic etc., can utilize cutting ring.Cutting ring is the cylinder of both ends open, and end opening has sword, and the height of cylinder and diameter are 5 cm.
If will sample darker soil, sampling tool the most frequently used is at present earth boring auger.Earth boring auger divides manual operations and mechanically actuated two class.Manual earth boring auger style is a lot of, has the short handle earth boring auger gathering shallow-layer soil sample, observes the screw terminal earth boring auger of about 1 meter soil layer interior profile feature, and it is laborsaving that the latter enters soil, be particularly useful for observing WATER LEVEL CHANGES, but it is little to gather soil sample amount.When gathering for chemical analysis or do not need the soil sample of physical analysis of undisturbed soil, use open type earth boring auger.Gather the undisturbed soil sample of not spoiled soil structure or shape, use telescopic earth boring auger.Machinery adopts earth boring auger by motor driving, makes drill body enter the soil of certain depth, is then put on by earth pillar, keep flat observation, cut sampling on demand.Earth pillar diameter can control with the drill body of different-diameter, as 5 centimetres, 10 centimetres or thicker.But for harder ground, the existing employing instrument distance that often the more difficult distance extending into less than one meter, the inside of soil is even darker, for the soil of deep layer, drilling tool creeps into difficulty, even small-sized drilling tool can not meet the demands, and large-scale drilling tool exists transport difficult, the shortcomings such as large are destroyed to soil surface.
utility model content:
The purpose of this utility model provides a kind of hard ground sampler for above-mentioned Problems existing, can extend into the distance sampling of less than a meter of hard ground, and structure is simply easy to carry, do not cause large destruction in the process of use to surface vegetation.
Above-mentioned object is realized by following technical scheme:
Hard ground sampler, comprise support, described frame upper is provided with rotating down pressing cylinder, the piston rod jointed rod of described rotating down pressing cylinder, described drilling rod comprises drill bit position and sampling point, described drill bit position and described sampling point are linked into an integrated entity by middle reducer, described drill bit position is twist drill, described sampling point is provided with one group of sampling groove, described sampling groove is provided with removable cover, described removable cover cylinder lever connecting rod, the external diameter at described drill bit position is greater than the external diameter of described sampling point.
Described hard ground sampler, the piston rod of described rotating down pressing cylinder is connected by cross key with described drilling rod.
Described hard ground sampler, the external diameter at described drill bit position is 1.05-1.15 times of the external diameter of described sampling point.
Beneficial effect:
1. the utility model adopts rotating down pressing cylinder and bit part is provided with auger bit, bore native power strong, for hard ground, be convenient to the distance sampling of less than a meter extending into hard ground, and structure is simply easy to carry, in the process of use, large destruction is not caused to surface vegetation.
2. the piston rod of rotating down pressing cylinder of the present utility model is connected by cross key with described drilling rod, and moment of torsion is large, reliable and stable work.
accompanying drawing illustrates:
Fig. 1 is structural representation of the present utility model.
In figure: 1, support, 2, rotating down pressing cylinder, 3, piston rod, 4, drill bit position, 5, sampling point, 6, reducer, 7, sampling groove, 8, removable cover, 9, pull bar.
embodiment:
Below in conjunction with the drawings and specific embodiments, illustrate the utility model further.Following embodiment should be understood and be only not used in restriction scope of the present utility model for illustration of the utility model.
As shown in Figure 1: the hard ground sampler of the present embodiment, comprise support 1, described frame upper is provided with rotating down pressing cylinder 2, piston rod 3 jointed rod of described rotating down pressing cylinder, described drilling rod comprises drill bit position 4 and sampling point 5, described drill bit position and described sampling point are linked into an integrated entity by middle reducer 6, described drill bit position is twist drill, described sampling point is provided with one group of sampling groove 7, described sampling groove is provided with removable cover 8, described removable cover cylinder lever connecting rod 9, the external diameter at described drill bit position is greater than the external diameter of described sampling point.
Hard ground sampler described in the present embodiment, the piston rod of described rotating down pressing cylinder is connected by cross key with described drilling rod.
Hard ground sampler described in the present embodiment, the external diameter at described drill bit position is 1.05-1.15 times of the external diameter of described sampling point.
Technological means disclosed in the utility model scheme is not limited only to the technological means disclosed in above-mentioned technological means, also comprises and is equal to by above technical characteristic the technical scheme that replacement forms.Unaccomplished matter of the present utility model, belongs to the common practise of those skilled in the art.
