Description
Technical field:
The utility model relates to a kind of Novel farmland soil collecting device, belongs to agriculture apparatus technical field.
Background technology:
In field irrigation process, often need farm environment, soil moisture content, nutrient migration, underground water distribution etc. to carry out network.Taking of soil sample or sample is a very important step, and geotome is a kind of important instrument that fetches earth of commonly using, it have easy to carry, fetch earth convenient, flexible, reduce the advantages such as labour, be widely used.
The geotome adopting in the middle of actual is of a great variety, can choose different sampling equipment according to the type of soil, depth of soil difference.When the more shallow sampling of soil layer, soil collecting is convenient, accurately error is relatively little.But (be generally greater than 20cm) when sampling depth is darker, in collector, the earth that fetches earth easily mixes the soil of different depth, representative poor, make test findings bigger error, can not accurate response go out to study the actual conditions of soil layer.
How accurately gathering the depth of investigation soil sample, avoid different soil soil mutually to mix the error causing experimentally, improve the accuracy of experiment and well react actual conditions, is an objective problem of needing consideration badly.Emphasis of the present invention is for worn-out mouthful of: (1) conventional earth boring auger sampling thief half slot without screening, and earth boring auger causes different soil soil mutually to mix in stressed downward penetration process; (2) after conventional earth boring auger has been sampled, utilize scraper manually to sample, the harder soil of this process especially soil property more consuming time, work efficiency is not high.The present invention has carried out corresponding improvement from above two aspects, thereby improves accuracy and the operability of test.
Existing soil sampler mainly contains T-shaped handle, stainless steel metal cylinder (have scale in metal cylinder, and offer semicircular notch according to dimension, notch place is soil sampling point), taper bit, hammer, scraper composition.In field test, in the vertical injection soil of sampling thief, soil crimp, in semicircular notch, the soil body enters metal collection tube.Take out sampling thief and utilize scraper that soil is plucked out, sampling completes.Its shortcoming is: sampling pipe bottom, without the measure of screening, causes sampling pipe to adopt in advance full pedotheque in sampling deep layer process, can not the actual soil properties of accurate response; In addition, increased soil density in sampling cylinder in the process that fetches earth, adopted scraper to pluck out difficulty, efficiency is not high.
Utility model content:
For the problems referred to above, the technical problems to be solved in the utility model is to provide a kind of Novel farmland soil collecting device.
A kind of Novel farmland soil collecting device of the present utility model, it comprises T-handle, spring, pull bar, hollow stem, handle, drill bit, collecting mechanism, T-handle is arranged on the upper end of hollow stem, handle is hinged on the upper end of T-handle, the front end of handle is provided with pull bar, the upper end of pull bar is socketed with spring, and pull bar is arranged on the inside of hollow stem, the lower end of hollow stem spins by the upper end of spin screw thread and collecting mechanism, the rotation screw thread of the lower end of collecting mechanism and drill bit upper end spins, described collecting mechanism comprises collection tube, sampling knife, three connecting rods, annular articulated elements, in collection tube, be hinged with three sampling knife, one end of three connecting rods is connected with the pin joint of sampling knife respectively, the other end of three connecting rods is connected with annular articulated elements, annular articulated elements is connected with the lower end of pull bar.
The beneficial effects of the utility model are: improved accuracy and the operability of test, work efficiency is high, easy and simple to handle, easy to use.
Accompanying drawing explanation:
For ease of explanation, the utility model is described in detail by following concrete enforcement and accompanying drawing.
Fig. 1 is structural representation of the present utility model;
Fig. 2 is that the A-A of Fig. 1 is to cut-open view.
In figure: 1-T shape handle; 2-spring; 3-pull bar; 4-hollow stem; 5-handle; 6-drill bit; 7-collecting mechanism; 717 collection tubes; 72-sampling knife; 73-tri-connecting rods; 74-annular articulated elements.
Embodiment:
For making the purpose of this utility model, technical scheme and advantage more cheer and bright, below by the specific embodiment shown in accompanying drawing, the utility model is described.But should be appreciated that, these descriptions are exemplary, and do not really want to limit scope of the present utility model.In addition, in the following description, omitted the description to known configurations and technology, to avoid unnecessarily obscuring concept of the present utility model.
As shown in Figure 1-2, this embodiment is by the following technical solutions: it comprises T-handle 1, spring 2, pull bar 3, hollow stem 4, handle 5, drill bit 6, collecting mechanism 7, T-handle 1 is arranged on the upper end of hollow stem 4, handle 5 is hinged on the upper end of T-handle 1, the front end of handle 5 is provided with pull bar 3, the upper end of pull bar 3 is socketed with spring 2, and pull bar 3 is arranged on the inside of hollow stem 4, the lower end of hollow stem 4 spins by the upper end of spin screw thread and collecting mechanism 7, the rotation screw thread of the lower end of collecting mechanism 7 and drill bit 6 upper ends spins, described collecting mechanism 7 comprises collection tube 71, sampling knife 72, three connecting rods 73, annular articulated elements 74, in collection tube 71, be hinged with three sampling knife 72, one end of three connecting rods 73 is connected with the pin joint of sampling knife 72 respectively, the other end of three connecting rods 73 is connected with annular articulated elements 74, annular articulated elements 74 is connected with the lower end of pull bar 3.
The principle of work of this embodiment is: when this sampling thief gathers soil, first sampling thief is vertically positioned over to sampled point, at T-handle position, apply downward pressure, when sampling thief arrives the test degree of depth, slowly pull-up handle 5, now give middle 3 one downward pressure of pull bar, pull bar 3 transmission of pressures are to end annular hinged end, pin joint declines, connect the stressed effect of three connecting rods 73 of sampling knife 72 and make sampling knife 72 rotate in the horizontal direction an angle, the edge of a knife outwards opens, simultaneously, sampling thief T-handle 1 is clockwise rotated, complete soil sampling, release handle, spring action due to handle handle place, intermediate draw bar is moved up, the stressed automatic closure of sampling knife, avoid different levels soil mutually to mix, after having sampled, repeat loose handle, three links in sampling cylinder, the up and down interior soil natural that makes of annular articulated elements and intermediate draw bar is loosening, easily complete sampling.
More than show and described ultimate principle of the present utility model and principal character and advantage of the present utility model.The technician of the industry should understand; the utility model is not restricted to the described embodiments; that in above-described embodiment and instructions, describes just illustrates principle of the present utility model; do not departing under the prerequisite of the utility model spirit and scope; the utility model also has various changes and modifications, and these changes and improvements all fall within the scope of claimed the utility model.The claimed scope of the utility model is defined by appending claims and equivalent thereof.
