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:
The method that soil sampling refers to gather pedotheque.Pollutant distribution in soil, the existing level difference caused because of the distance apart from polluter, also have the vertical differentiation caused because of time and the difference of other factors, thus also to gather soil sample according to soil profile layer layering.The most frequently used sampling tool is 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, is particularly suited for observing WATER LEVEL CHANGES, but it is little to gather soil sample amount.Machinery is adopted earth boring auger and is driven by motor, 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, such as 5 centimetres, 10 centimetres or thicker.Deep soil is taken a sample to research use through frequently with modes such as degree of depth excavations, then utilized some above-mentioned instruments to be sampled, easily to damaging property such as surface vegetations, and wasted time and energy.
In order to solve the problems referred to above, Chinese patent CN201320462243 discloses a kind of deep soil sampler, and specifically disclose techniques below feature: this deep soil sampler, including 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, one group of sampling groove it is uniformly distributed on described thief rod, on each described sampling groove, there is cover plate, described cover plate is linked together by pull bar, there is on described thief rod cover plate slideway.Although the mode that this employing multistage hydraulic cylinder drives can reach the purpose of deep layer sampling, but the cost of multistage hydraulic cylinder is high, and to carry fueller at any time, very inconvenient, the sample point of major part soil investigation is all in field, wilderness, carry the heavy instrument of this volume to be not easy to work and carry out, affect sampling efficiency.
Summary of the invention:
It is an object of the invention to provide a kind of hand-operated lever-type soil sample collector for the problem of above-mentioned existence, use manual actuation, it is not necessary to by means of other auxiliary powers, easy to carry, it is simple to improve soil sample efficiency.
Above-mentioned purpose is realized by following technical scheme:
Hand-operated lever-type soil sample collector, including mounting bracket, by liftable support hinged lever in described mounting bracket, one end of described lever connects thief rod, and the other end of described lever connects two steel wire ropes, and wherein the fixed pulley being arranged on described mounting bracket top walked around by a described steel wire rope, another described steel wire rope naturally droops, it is provided with sampling groove on described thief rod, described sampling groove is provided with removable cover, described removable cover cylinder lever connecting rod.
Described hand-operated lever-type soil sample collector, described liftable support includes fixed plate, and described fixed plate is provided with jackscrew, and described fixed plate is arranged in described mounting bracket by jackscrew.
Described hand-operated lever-type soil sample collector, one end that described lever is positioned at described thief rod is provided with two depression bars vertical with described thief rod axis.
Beneficial effect:
1. the present invention uses hand-operated lever-type to drive, it is to avoid the equipment using hydraulic jack to drive in Chinese patent CN201320462243 is heavy and carries the problem of inconvenience, and sampling is convenient, and sampling efficiency is high.
2. the present invention uses depression bar auxiliary to push, and balance is good.
Accompanying drawing illustrates:
Fig. 1 is the structural representation of the present invention.
In figure: 1, mounting bracket, 2, lever, 3, thief rod, 4, steel wire rope, 5, fixed pulley, 6, sampling groove, 7, removable cover, 8, pull bar, 9, fixed plate, 10, jackscrew, 11, depression bar.
Detailed description of the invention:
Below in conjunction with the accompanying drawings and specific embodiment, it is further elucidated with the present invention.It should be understood that following detailed description of the invention is merely to illustrate the present invention rather than limits the scope of the present invention.
As shown in Figure 1: the hand-operated lever-type soil sample collector of the present embodiment, including mounting bracket 1, by liftable support hinged lever 2 in described mounting bracket, one end of described lever connects thief rod 3, the other end of described lever connects two steel wire ropes 4, wherein the fixed pulley 5 being arranged on described mounting bracket top walked around by a described steel wire rope, another described steel wire rope naturally droops, sampling groove 6 it is provided with on described thief rod, removable cover 7, described removable cover cylinder lever connecting rod 8 it is provided with on described sampling groove.
Hand-operated lever-type soil sample collector described in the present embodiment, described liftable support includes fixed plate 9, and described fixed plate is provided with jackscrew 10, and described fixed plate is arranged in described mounting bracket by jackscrew.
Hand-operated lever-type soil sample collector described in the present embodiment, one end that described lever is positioned at described thief rod is provided with two depression bars 11 vertical with described thief rod axis.
Work process: when needing sampling, mounting bracket is put well, then regulation liftable support is placed on suitable height, one end regulations and parameters being connected by pulling this steel wire rope walking around fixed pulley with steel wire rope is upturned, one end that lever is connected with thief rod simultaneously is just to lower stress, in order to increase stability, the one end being positioned at described thief rod on the lever of the present invention is provided with two depression bars vertical with described thief rod axis, can with other staff under press, before pressing under thief rod, cover plate is closed simultaneously, pull pull bar until thief rod is depressed into the degree of depth needing to use to be opened by cover plate, then soil is made to enter in sampling groove by rotation thief rod, again cover plate is closed.Pulling another steel wire rope naturally drooped afterwards makes the other end of lever fall, and sampling rod end lifts, and takes out thief rod, collects the soil collected.
Technological means disclosed in the present invention program is not limited only to the technological means disclosed in above-mentioned technological means, also includes the technical scheme being made up of above technical characteristic equivalent.The unaccomplished matter of the present invention, belongs to the common knowledge of those skilled in the art.
