Abstract
The utility model relates to an agriculture equipments in particular to a corn slope of repose fast tester. The tester is realized by the following technology plan. The tester comprises a soleplate, a test plate, probes, an instrument mount, a lift arm and slings. The instrument mount is fixed on the soleplate, the lift arm is hinge jointed on the upper extreme of the instrument mount, a plurality of slings of equal length with one end connected to a plurality of matched part equal points surround the test disk. The other ends of the slings are collected together and are connected together to one end of another sling with the other end connected to the lift arm. The probe is fixed on the center part of the test disk. The utility model has the advantages that, the corn slope of repose can be got precisely only by shaking the lift device and testing the scale that the corn heap conical surface is on the probe. The testing is fast and precise, meanwhile the utility model is convenient to be made and carried and has a relatively good utility value.
Description
Technical field
The utility model relates to agricultural tool, relates in particular to a kind of angle of repose high speed tester.
Background technology
All be provided with seed-box on the seeder, the seed in the case is flowed out by the bucket shape discharging opening of lower end, enters feed mechanism for seed.Can seed evenly flow out and be emptied completely all relevantly with the bucket shape discharging opening inclination angle of seed-box downside, and this inclination angle is associated with the angle of repose of cereal.The seed-box seeding is evenly smooth in order to guarantee to sow a certain cereal, and can be emptied completely, and all will design seed-box according to the angle of repose of this cereal of prior mensuration.Angle of repose is meant the cone shape cereal that a pile is stacked naturally, the angle of its circular conical surface and baseplane.
The measurement at existing angle of repose is very coarse, estimates several places base diameter that this heap cereal with tape measure, calculate mean diameter D, measure the height h of this heap cereal, try to achieve the angle of repose with trigonometric function.Because the no clear boundary in cereal bottom generally all is estimation, grain mass height h is not the awl height of this heap cereal, so the angle of repose error that obtains is bigger, often influences the design of seed-box, makes it can not reach preferable discharging state.
Summary of the invention
The purpose of this utility model is to overcome the deficiencies in the prior art, designs comparatively accurately angle of repose high speed tester efficiently again of a kind of measurement, and is achieved through the following technical solutions:
It comprises base plate, test plate, probe, instrument stand, lift arm and lifting rope, described instrument stand is fixed on the base plate, lift arm is hinged on the upper end of instrument stand, one end of some equal length lifting ropes connects with the corresponding some equal portions points of test plate week side, the other end of these some lifting ropes compiles a place and a common end that connects another lifting rope, the other end of this another lifting rope is connected on the lift arm, and probe stationary is on the position of test plate center one side.
Described probe is vertically fixed on circumferential edges 10 centimeters apart from described disk.
Described probe is marked with scale.
Described lift arm is hinged by the rotating shaft and the instrument stand at two ends, is connected with rocking handle in the rotating shaft of one end.
The beneficial effects of the utility model are: only need shake lifting gear, record cereal and pile the angle of repose that the conical surface residing scale on probe just can more accurately obtain this kind cereal, measurement is also comparatively accurate fast, and the utility model is easy to make simultaneously, and being easy to carry has good practical values.
Description of drawings
Fig. 1 is the utility model structural representation
Among the figure, the 1st, test plate, the 2nd, base plate, the 3rd, instrument stand, the 4th, lift arm, the 5, the 6th, lifting rope, the 7th, probe, the 8th, rocking handle, the 9th, rotating shaft.
Embodiment
Below in conjunction with drawings and Examples the utility model is described further.
Please contrast Fig. 1, instrument stand 3 is fixed on the base plate 2, and the diameter of test plate 1 is 280mm, apart from the inboard place of its circumferential edges 100mm vertical fixing one probe 7 is arranged at this disk, and this probe is marked with scale, and the meter full scale of probe generally designs at 40～120mm.One end of the lifting rope 5 of 4 equal lengths is connected on four equal portions points of test plate 1 circumferential edges, and its other end is connected with an end of lifting rope 6, and the other end of lifting rope 6 is connected with lift arm 4.Lift arm 4 is rectangle frames made from steel wire, is welded with a rotating shaft 9 respectively in its center, both sides, and lift arm 4 is hinged by this rotating shaft and instrument stand 3, is connected with rocking handle 8 in the outside of a rotating shaft.
During the test angle of repose, cereal is deposited on disk 1 and the base plate 2, buries the dish degree of depth, bury the dish degree of depth and require greater than 160mm until regulation.Shake rocking handle 8 again and slowly promote test plate 1, away from the cereal layer on the base plate 2, the scale H of cereal heap conical surface on probe 7 calculates tan when reading this
-1(H/10) value can obtain the angle of repose of this kind cereal.The utility model product test fast and comparatively accurate is carried also very convenient.
Claims (4)
