Description
Technical field
The utility model relates to a kind of angle detection device, particularly a kind of seed repose angle pick-up unit.The utility model is mainly practically applicable to the fast detecting of seed repose angle, and the utility model belongs to seed science and technology field.
Background technology
The repose angle of seed also claims natural angle of slope, refers to that seed falls in one plane naturally from certain altitude, while reaching a great deal of, and the angle that the inclined-plane of formed cone is become with bottom circular diameter.It can be used as weighs the good and bad index of seed free flowability.
In seed scientific and engineering field, the free flowability of seed is relevant with processing after the classification of seed, shape, size, moisture, snotter, results and holding conditions etc.Seed grain is larger, the subsphaeroidal and smooth surface of shape, and free flowability is better.If be mixed with the situations such as various light snotteres, seed damage, free flowability greatly reduces.Seed moisture content content is higher, and intergranular friction power is larger, and its free flowability is corresponding minimizing also.Repose angle is larger, and seed mobility and free flowability are less; Otherwise repose angle is less, seed mobility and free flowability are larger.
The size of repose angle and the storage of seeds and seed process carrier are selected, processing technology and storage etc. are in close relations, as build seed granary, will estimate the wall pressure size that bulkhead bears according to seed free flowability, as the foundation of selecting building materials and structural type; In purification of seeds, conveying and keeping, all have important production meaning, as transported kind of a period of the day from 11 p.m. to 1 a.m with conveyor, its gradient should be adjusted to the repose angle that is slightly less than seed, in order to avoid seed flows backwards.In seed keeping process, particularly put in storage the initial stage, by detect seed repose angle have unchangedly predict whether seed gets damp again, dewfall, perspiration be so that heating is gone mouldy, to further check, and take measures in time, in case cause windfall loss.
For the measurement of repose angle, at present domestic still unified specialty is for the product of seed repose angle pick-up unit, to seed produce and teaching in seed repose angle is detected and causes difficulty.Main problem has: pick-up unit is coarse, it is inconsistent to detect seed sample amount, and seed sample height of drop can not free adjustment, inconvenient operation, the inaccurate series of problems that waits of measurement result.
Therefore, for seed, produce and the demand of teaching to seed repose angle pick-up unit, develop a kind of simple, practical seed repose angle pick-up unit, that this device has is simple in structure, it is accurate, easy to operate to measure, work efficiency is high, the advantage such as applied widely, to accurate evaluation seed quality and carry out the related works such as seed production, scientific research, teaching and have important practical usage.

The purpose of this utility model is not enough for prior art, provide a kind of simple in structure, detect the pick-up unit that reads seed repose angle intuitive and convenient.
The utility model is measured simple and easy methods in conjunction with two kinds of seed repose angle and is carried out: method one, in transparent plastic box, pack seed sample into, volume accounts for 1/3 of box volume, and the plastic casing that side is perpendicular slowly (rotates 90 to laying across
0angle), make the wherein seed that fills become an inclined-plane, mobile transparent plastic height and angular measurement plate record this inclined-plane and surface level angulation, i.e. repose angle (as ∠ A in Fig. 5); Method two, within adding kind of device putting hole, fixedly mix up height add kind of a device, seed sample falls within transparent plastic box bottom surface by adding kind of a device, form a cone (approximate circle cone), adopt transparent plastic height and angular measurement plate to record the gradient on cone both sides, i.e. repose angle (as ∠ B in Fig. 6).
For realizing above-mentioned technical purpose, the utility model is by the following technical solutions: a kind of seed repose angle pick-up unit, and it comprises: the transparent plastic box body (long 30 centimetres, wide 10 centimetres, high 15 centimetres) with level meter fixed orifice (the horizontal instrument of bubbles), level adjuster and slot; With ruler scale, 1/3 separatrix, 2/3 marginal plastic slab; Transparent plastic height and angular measurement plate with ruler scale and major-minor protractor scale; With height-adjustable kind of the device that adds of ruler scale; The seed-container (long 10 centimetres, wide 10 centimetres, high 15 centimetres) of being simultaneously furnished with certain volume.
Further, described transparent plastic box horizontal positioned and vertically placement left backward.
Further, described in, add kind of device putting hole and do not filling special-purpose stopper sealing of hole while adding kind of device.
Further, described plastic slab inserts envelope box from the slot mouth on transparent plastic box body right side, can utilize plate moving handle to move left and right.
Further, described transparent plastic height and angular measurement plate are placed between slot, can utilize its moving handle to move left and right, and can turned upside down use simultaneously.
Adopt after technique scheme, the utlity model has following beneficial effect:
(1), according to the position of transparent plastic box body upper level instrument bubble, the level adjuster of damper box bottom, makes transparent plastic box body bottom surface in horizontality, has increased measuring accuracy;
(2) adopt above-mentioned detection method one, first mix up device horizontality, after adopting supporting seed-container that a certain amount of seed (1/3 box body volume) is poured in the transparent plastic box of putting upside down, plate is inserted, first plastic casing being erect to place makes seed upper surface locate in 1/3 separatrix, after by after plastic casing slow circumvolve 90 degree, traverse measurement plate, after being alignd with the horizontal summit of seed heap, protractor scale center origin can directly read the repose angle of seed heap, easy to operate, measuring accuracy is high, and between measurement result repeats, error is little;
(3) adopt above-mentioned detection method two, first mix up device horizontality, mix up to add kind of device height and be fixed on and add kind of a device putting hole place, if after the height of drop of good seed, add a certain amount of seed, seed forms cone (approximate circle cone), traverse measurement plate in bottom, measuring method, with detection method one, can quick and conveniently accurately read the repose angle of seed heap.
The utility model is simple in structure, detect read seed repose angle simple, convenient, accurately, error is little, has good practicality.
