Abstract
The utility model discloses a pressure immersion type wheat hardness detector, which comprises a measuring table and a support perpendicularly disposed on the measuring table. A sliding block capable of moving up and down is screwed on a working lead screw driven by a servo motor and disposed at the upper end of the support. A perpendicularly downwards pressing rod is disposed at the end portion of a cross rod horizontally and fixedly connected on the sliding block. A pressure sensor is arranged on the cross rod close to the pressing rod. A wheat container is movably placed on the measuring table. A measuring hole is disposed at the central position of a pressing cover screwed on the wheat container. The pressing rod is inserted in an inner cavity of the wheat container from the measuring hole. The pressure immersion type wheat hardness detector has the advantages of 1 having remarkable linear dependence with foreign common wheat hardness measurement methods, 2 not requiring to smash wheat particles, performing one-time pressure immersion, shortening smashing process and measuring time and achieving standardization of measuring methods and instruments, and 3 being simple and fast to measure, high in resolution ratio, low in instrument price and easy to popularize.
Description
Technical field
The utility model relates to the wheat quality detecting instrument, especially relates to a kind of pressure immersion wheat hardness detector of fast nearly non-destructive determination wheat hardness.
Background technology
The soft or hard of wheat kernel texture is to estimate an important indicator of wheat processing quality and edible quality, is one of important evidence of wheat market classification and price, wheat hardness detect to the deciding grade and level of wheat science, science process, that the raising wheat flour goes out rate is very important.The wheat hardness Study on Theory has been continued more than 100 year both at home and abroad, the method for measuring wheat hardness also has kind more than 100.According to measuring principle, can be divided into organoleptic examination method, resistance to compression force method, polishing, near infrared method etc.But these methods or waste time and energy, can not The real time measure, or cost of determination is too high can't popularize.Used testing tool not only complex structure, do not have China's independent intellectual property right, and cost an arm and a leg.
Summary of the invention
The purpose of the utility model be to provide a kind of simple in structure, detect fast, result's pressure immersion wheat hardness detector accurate, with low cost.
For realizing above-mentioned purpose, the utility model can be taked following technical proposals:
The described pressure immersion of the utility model wheat hardness detector; It comprises measuring table and is vertically set on the support on the said measuring table; Be arranged on the work screw mandrel that the servomotor of support upper end drives and screw the slide block that moves up and down; The crossbar end that level is connected on the said slide block is provided with depression bar vertically downward, is provided with pressure transducer near the cross bar of depression bar; Activity is placed with and contains the wheat container on said measuring table, is screwed in the gland center of containing on the wheat container and offers gaging hole, and said depression bar inserts from gaging hole and contains in the wheat container intracavity.
Said work screw mandrel outer setting has guard shield; The cross bar that is connected on the slide block moves up and down along vertical groove of offering on the guard shield.
Said servomotor top is provided with displacement encoder.
The advantage of the utility model is that one is to have significant linear dependence with external wheat hardness assay method commonly used; The 2nd, need not to pulverize wheat grain, one time pressure immerses, and has reduced the crushing process flow process, has shortened minute, has realized the standardization of assay method and instrument; The 3rd, mensuration is simple, quick, resolution is higher, and the instrument price is low, is easy to popularize.

Embodiment
As shown in Figure 1; The described pressure immersion of the utility model wheat hardness detector; It comprises measuring table 1 and is vertically set on the support 2 on the measuring table 1; Be arranged on the work screw mandrel 4 that the servomotor 3 of support upper end drives and screw the slide block 5 that moves up and down, cross bar 6 ends that level is connected on the slide block 5 are provided with depression bar 7 vertically downward, are provided with pressure transducer 8 near the cross bar 6 of depression bar 7; Activity is placed with and contains wheat container 9 on measuring table 1, is screwed in gland 10 centers of containing on the wheat container 9 and offers gaging hole, and depression bar 7 inserts from gaging hole and contains in wheat container 9 inner chambers; In work screw mandrel 4 outer setting guard shield 11 is arranged; The cross bar 6 that is connected on the slide block 5 moves up and down along vertical groove of offering on the guard shield 11, above servomotor 3, is provided with displacement encoder 12.
During detection, the wheat of certain mass packed into contains in the wheat container 9, through vibration with certain pressure with its compacting.Work screw mandrel 4 drives depression bar 7 and is pressed in the wheat; Stressed when depression bar 7 is pressed on the pressure transducer 8 begins to change the compression distance through microprocessor control servomotor 3, displacement encoder 12 control depression bars 7; Pressure transducer 8 on the depression bar 7 is accepted the stressed variable signal of depression bar 7 and is transferred to microprocessor, and signal is handled and outputed on the LCDs, directly reads the result; The measurement rear slider automatically resets, and makes things convenient for continuous coverage.
The pressure transducer 8 that servomotor 3 drives on the slide block 5 through work screw mandrel 4; Depression bar 7 is inserted in the Sheng wheat container 9 with certain speed; Relation according to compression distance and pressure (determination of pressure sensor) calculates wheat hardness, measures rear slider and automatically resets, and makes things convenient for continuous coverage.
