Hand-operated lever-type soil sample collector
technical field:
The present invention relates to a kind of soil sample equipment, be specifically related to a kind of hand-operated lever-type soil sample collector.
background technology:
Soil sampling refers to the method that gathers pedotheque.The distribution of pollutant in soil, the existing level difference because causing apart from the distance of pollution sources, also has the vertical differentiation causing because of the difference of time and other factors, thereby also will gather soil sample according to soil profile layer layering.The most frequently used sampling instrument is earth boring auger.Earth boring auger divides manual operations and mechanically actuated two classes.Manual earth boring auger style is a lot of, has the short handle earth boring auger that gathers shallow-layer soil sample, observes the screw terminal earth boring auger of 1 meter of left and right soil layer interior profile feature, and it is laborsaving that the latter enters soil, is particularly useful for observing WATER LEVEL CHANGES, but it is little to gather soil sample amount.Machinery is adopted earth boring auger by motor driving, makes drill body enter the soil of certain depth, then earth pillar is put on, and keeps flat observation, cutting sampling on demand.Earth pillar diameter can be with the drill body control of different-diameter, as 5 centimetres, 10 centimetres or thicker.The modes such as the frequent employing tap/dip deep into adopting for taking a sample to research of deep soil, then utilized some above-mentioned instruments to sample, and easily to damaging property such as surface vegetations, and wasted time and energy.
In order to address the above problem, Chinese patent CN201320462243 discloses a kind of deep soil sampler, and specifically disclose following technical characterictic: this deep soil sampler, comprise fixed support, upside-down mounting multistage hydraulic cylinder on described fixed support, the cylinder bottom of described multistage hydraulic cylinder is fixed on described support, the piston rod of described multistage hydraulic cylinder connects thief rod, the head of described thief rod is tip-angled shape, on described thief rod, be uniformly distributed one group of sampling groove, on each described sampling groove, there is cover plate, described cover plate links together by pull bar, on described thief rod, there is cover plate slideway.Although the mode that this employing multistage hydraulic cylinder drives can reach the object of deep layer sampling, but the cost of multistage hydraulic cylinder is high, and to carry at any time fueller, very inconvenient, the sample point of most of soil investigation is all in field, wilderness, carry the instrument work of being not easy to of this volume heaviness and carry out, affect sampling efficiency.
summary of the invention:
The object of the invention is provides a kind of hand-operated lever-type soil sample collector for the problem of above-mentioned existence, adopts manual actuation, need to be by means of other auxiliary powers, and easy to carry, be convenient to improve soil sample efficiency.
Above-mentioned object realizes by following technical scheme:
Hand-operated lever-type soil sample collector, comprise mounting bracket, on described mounting bracket, pass through liftable support hinged lever, one end of described lever connects thief rod, and the other end of described lever connects two wire rope, and wherein the wire rope described in is walked around the fixed pulley that is arranged on described mounting bracket top, wire rope described in another naturally droops, on described thief rod, be provided with sampling groove, on described sampling groove, be provided with removable cover, described removable cover cylinder lever connecting rod.
Described hand-operated lever-type soil sample collector, described liftable support comprises fixed head, on described fixed head, is provided with jackscrew, described fixed head is arranged on described mounting bracket by jackscrew.
Described hand-operated lever-type soil sample collector, the one end that is positioned at described thief rod on described lever is provided with two depression bars vertical with described thief rod axis.
Beneficial effect:
1. the present invention adopts hand-operated lever-type to drive, and has avoided in Chinese patent CN201320462243, adopting the equipment heaviness of hydraulic jack driving and carrying inconvenient problem, and sampling is convenient, and sampling efficiency is high.
2. the present invention adopts the auxiliary pushing of depression bar, and balance is good.
brief description of the drawings:
Fig. 1 is structural representation of the present invention.
In figure: 1, mounting bracket, 2, lever, 3, thief rod, 4, wire rope, 5, fixed pulley, 6, sampling groove, 7, removable cover, 8, pull bar, 9, fixed head, 10, jackscrew, 11, depression bar.
detailed description of the invention:
Below in conjunction with the drawings and specific embodiments, further illustrate the present invention.Should understand following detailed description of the invention is only not used in and limits the scope of the invention for the present invention is described.
As shown in Figure 1: the hand-operated lever-type soil sample collector of the present embodiment, comprise mounting bracket 1, on described mounting bracket, pass through liftable support hinged lever 2, one end of described lever connects thief rod 3, the other end of described lever connects two wire rope 4, wherein the wire rope described in is walked around the fixed pulley 5 that is arranged on described mounting bracket top, wire rope described in another naturally droops, on described thief rod, be provided with sampling groove 6, on described sampling groove, be provided with removable cover 7, described removable cover cylinder lever connecting rod 8.
Hand-operated lever-type soil sample collector described in the present embodiment, described liftable support comprises fixed head 9, is provided with jackscrew 10 on described fixed head, described fixed head is arranged on described mounting bracket by jackscrew.
Hand-operated lever-type soil sample collector described in the present embodiment, the one end that is positioned at described thief rod on described lever is provided with two depression bars 11 vertical with described thief rod axis.
The course of work: need to sample time, mounting bracket is put well, then regulate liftable support to be placed on suitable height, walk around one end that this wire rope of fixed pulley makes regulations and parameters be connected with wire rope is upturned by pulling, one end that lever is connected with thief rod is simultaneously just to lower stress, in order to increase stability, the one end that is positioned at described thief rod on lever of the present invention is provided with two depression bars vertical with described thief rod axis, can coordinate and press down by other staff, simultaneously thief rod presses down and front cover plate is closed, by the time when thief rod is depressed into the degree of depth that needs employing, pulling pull bar opens cover plate, then by rotation thief rod, soil is entered in sampling groove, again cover plate is closed.Pull afterwards another wire rope naturally drooping the other end of lever is fallen, sampling rod end lifts, and takes out thief rod, collects the soil collecting.
The disclosed technological means of the present invention program is not limited only to the disclosed technological means of above-mentioned technological means, also comprises by above technical characterictic and is equal to the technical scheme that replacement forms.Unaccomplished matter of the present invention, belongs to those skilled in the art's common practise.
