Abstract
The utility model provides a humidity testing standard box for crops. A portable humidity tester is usually used for humidity test for crops such as wheat straws and the like at present, and both imported and domestic humidity testers use resistance change between two electrodes under different humidity to induce humidity of objects to be tested. However, the crops such as wheat straws and the like are usually conveyed after packaging, and the humidity test is not accurate due to large density differences. The technical scheme includes that the standard box comprises a cover board which can be placed in the box or taken out after detachment. Straws to be detected are placed into the standard box after sampling, standard pressure is exerted on the cover board, a humidity tester is inserted in the box, and accurate test can be achieved. The humidity testing standard box for the crops has the advantages of accurate, fast and convenient detection and unified standards.
Description
Technical field: the invention belongs to the humidity measurement field, relate in particular to crops humidity measurement standard container.
Background technology: the present humidity measurement portable humidity tester commonly used of crops such as wheat straw, be external import or homemade all be to rely on the variation of two resistance between electrode under the different humidity to respond to the humidity of measured object.But crops such as wheat straw are wanted packing and transporting usually, and density differs greatly, thereby cause humidity measurement inaccurate.
Summary of the invention: the purpose of invention: accurate for a kind of mensuration is provided, operation has the crops humidity measurement standard container of certain standard.
In order to reach as above purpose, the present invention takes following technical scheme: said casing comprises can be placed on the also removable cover plate of taking out in its inside.
Further technical scheme of the present invention is: said casing also comprises the hygrometer that can insert wherein.
Further technical scheme of the present invention is: said casing comprises the hole.
Further technical scheme of the present invention is: on the said hole lid is arranged.
With putting into standard container after the stalk sampling to be measured, put on it in order to normal pressure, insert humidity tester again, can reach the purpose of accurate test.
After the test relatively of the standard container of actual fabrication, the wheat straw density of not separating bundle not simultaneously, humidity differs more than 10%, use the standard container test after, humidity differs about 1%.Realized the accurate test of humidity when the peasant sends wheat straw here, made it convincing the moisture of deducting in view of the above.
Adopt the as above crops humidity measurement standard container of technical scheme, have following beneficial effect: measure accurately, convenient and swift, unified standard.
Description of drawings: in order to further specify the present invention, further describe below in conjunction with accompanying drawing: accompanying drawing is the structural representation of invention:
Wherein: 1. cover plate; 2. casing; 3. hygrometer; 4. hole; 5. crop sample.
Embodiment: below in conjunction with accompanying drawing embodiments of the invention are described, embodiment is not construed as limiting the invention:
Said casing 2 comprises can be placed on the also removable cover plate of taking out 1 in its inside.
Further technical scheme of the present invention is: said casing 2 also comprises the hygrometer 3 that can insert wherein.
Further technical scheme of the present invention is: said casing 2 comprises hole 4.
Further technical scheme of the present invention is: on the said hole 4 lid is arranged.
Normal pressure acts on the cover plate 1, has guaranteed equilibrium.
The 4 assurance external worlds, hole do not influence use, can not cause the humidity error.
With putting into casing 2 after crop sample 5 sampling, cover cover plate 1, apply proof force after, with testing humidity in the hygrometer 3 insertion crops.
Also can standard container be changed into containers such as standard bag, insert hygrometer 3 tests, also can reach same effect, similarly be equal to replacement and the present invention is not caused restriction.
The stalk of said usefulness does not for example cause restriction to the use kind of crops and the scope of application of this device.
Because that writes is non exhaustive, the embodiment of this patent does not receive the restriction of above examples of implementation, and similarly embodiment is also in protection scope of the present invention.
