Background technology
Online seed moisture content detection technique is mainly used in seed dryer, is the vitals realizing automated seed drying and processing equipment. Online seed moisture content is accurately measured, it can be ensured that seed can dry suitable moisture content value, in order to preserve and following process. If drying and processing is improper, for instance seed moisture content too high causing is susceptible in seed storing process go mouldy or germinate; And seed moisture content is too low will cause that seed activity is deteriorated, and reduce germination percentage.
Chinese Patent Application No. be 200410066206.0 patent documentation disclose a kind of condenser type seed moisture content on-line sensor technology with weight compensating, its patent readme describe: this invention includes the parts such as LOAD CELLS, weighing tray, sector dividing plate, wheel disc, drive motor, capacitance measurement pole plate, cylindrical baffle, discharging opening, support side plate, base; This invention is suitable for online Non-Destructive Testing seed moisture content, and adds weight compensating and temperature-compensating, decreases the seed distribution impact on certainty of measurement. The wheeling disk structure with sector dividing plate that this invention adopts, although achieving weight measurement dexterously, but after dropping into a sector due to seed, with in wheel disc rotation process, sector dividing plate is more and more narrow with the slit of cylindrical baffle, can be likely to cause seed and be caught broken breakage; Additionally in wheel disc rotation process, seed is dropped in the gap between wheel disc and support side plate, also leads to the breakage of seed, and can cause that wheel disc rotary resistance change affects greatly the rotation of wheel disc; Although raising machining accuracy, can avoid seed to drop in slit to a certain extent, but owing to less dust and impurity can fill up and support big space gradually, final it is possible to cause falling into of seed.
Summary of the invention:
The present invention is directed to the deficiencies in the prior art, it is proposed to a kind of lossless online moisture detector of the seed with auxiliary electrode pair for seed dryer. In order to reduce the damage to seed, this invention simplifies frame for movement, decrease moving component, increase sealing member, guarantee that seed will not enter slit and cause seed damaged as far as possible; Seed falls into detecting instrument and outflow monitoring instrument is by discharge door control, relies on the gravity of seed self to complete, decreases the probability of seed abrasion; Adopt multiple measurement electrode, it can be ensured that during main electrode measurement, seed can be full of whole electrode space, the accuracy ensured that simultaneously.
The present invention realizes according to following technical scheme.
A kind of lossless online moisture detector of multi-electrode seed, including casing, in this casing, middle part is provided with the chamber that gathers materials, this chamber that gathers materials is arranged over charging aperture, it is connected with discharge door, it is characterized in that, from top to bottom be pasted with inside the described cavity wall that gathers materials auxiliary electrode to main electrode pair, it is additionally provided with panel in described casing, the discharging motor being connected with this panel, door linkage and temperature sensor, described discharging motor is connected with discharge door by door linkage, control discharge door to open and closedown, described main electrode to auxiliary electrode to being connected with described panel respectively, described temperature sensor is fixed on described main electrode to upper, bottom in described casing, the side of opening of discharge door is additionally provided with discharging opening.
One end of described discharge door and cavity wall bottom-hinged of gathering materials.
The other end at described discharge door is connected to discharge door hairbrush.
It is coated with sealing film with the cavity wall junction that gathers materials at described discharge door.
Also include being connected with described panel close door position sensor and this pass door position sensor of opening position sensor and opening position sensor is separately fixed at described casing inner bottom part.
Panel control discharging motor rotates, and drives discharging linkage, drives discharge door Guan Bi, when detecting that position sensor signal of closing the door exports, controls discharging motor stalling, and discharge door completely closes; When seed is in time falling above, seed is constantly deposited in the intracavity portion that gathers materials, when seed pile height to a certain extent time, signal, to producing signal output, and is passed to panel by auxiliary electrode; Panel receives this signal, starts main electrode to carrying out seed moisture measurement; Meanwhile, the temperature of seed passes through the good main electrode of heat conductivility to being transmitted to temperature sensor; Panel passes through main electrode the detection with temperature sensor, it is possible to accurately obtain seed water fraction data; After completing measurement, panel controls discharging motor, drives discharging linkage, drives discharge door to open; When opening position sensor exports signal, panel controls discharging motor stalling, and discharge door fully opens, and releases seed, completes one-shot measurement. Owing to discharge door is equipped with discharge door hairbrush in discharge door closing course, seed during Guan Bi, will not be caught broken; Discharge door and the cavity wall junction that gathers materials cover sealing film, and therefore discharge door is hinged with the cavity wall that gathers materials goes out to will not fall into seed and decrease the abrasion of seed.
The actively progressive effect of the present invention is in that:
1, simplifying frame for movement, when discharge door is closed, seed is at water content detection instrument internal stacking, even density, it is ensured that the repeatable accuracy of measurement naturally, decreases the abrasion of seed.
2, sealing film and hairbrush are added on a movable element, it is to avoid seed enters the chance of slit, decreases the damage to seed equally, guarantees the reliability of detecting instrument longtime running simultaneously.
3, add auxiliary electrode pair, be used for detect seed pile with height, it is ensured that main electrode to measure precision
4, auxiliary electrode pair and main electrode are to when adopting diverse ways to measure, for instance employing resistance is sent out measurement, main electrode to adopting capacitance measurement by auxiliary electrode, it is also possible to mutually calibrate, thus improving certainty of measurement.
