Abstract

The utility model provides a grain storage insect detecting device of controlling impurity. A convex joint is affected by a probe conveying sleeve pipe, so the detecting device can be conveyed into the definite detection region of the grain pile, the detecting device which does a friction motion with the grain in the conveying can cause the entering of the impurity can be avoided, and the impurity is entered by an insect luring hole. The traction cable is adopted to draw the detecting device to a definite direction. A detecting funnel is connected with a guide tube, so the distance consistency between sensor elements are assured, the sensors which are installed in disorder can cause error is avoided, the insect can be lured and trapped, the impurity of the grain pile can be controlled, the error can be decreased, and the sensitivity can be improved. The utility model can be solely used for the no-impurity detection of the grain storage insect and can be assembled with a plurality of sensors.

Description

Controlled impurity grain storage pest checkout gear

Technical field:

This practicality newly relates to a kind of grain storage pest checkout gear that is used for controlled impurity.

Background technology:

Grain storage pest harm caused economic loss ten serious during grain was hidden, and for this reason, needed regularly to detect the pest species and the density of grain heap, can be control of insect foundation is provided.Grain storage pest detection method commonly used mainly adopts skewer to get the method detection grain worm that the grain sample sieves, but in actual applications, workload is big, labour intensity is high, poor working environment because sample jigs, and is subjected to certain restriction in actual applications.

China utility model patent ZL90209011.9 is a kind of grain worm trap checkout gear that utilizes the design of grain storage pest crawler behavior, do not add any inducing substance and can directly from the grain heap, catch insect, operating efficiency can increase substantially, also for realizing that the number of pest sensing provides a kind of important aid.

Chinese invention patent ZL92102125.9 improves this patent: with grain worm trap checkout gear is instrument, cooperate with devices such as detecting funnel, grain worm trash eliminator, sensor for countering, realization is caught number of pest to grain worm trap checkout gear and is counted automatically, for grain feelings computer monitoring provides a kind of desirable grain storage pest quantity sensing device.

China's utility model patent 02222946.9 realizes that with this patent of invention number of pest sensing major technique feature is identical, but do not consider practical China Oil and Food Import and Export Corporation heap Control of Impurities problem, what cause photosensors record thus is not only insect, and impurity arranged, the detection error is higher, be only limited at the grain face and use, can not reflect the grain heap insect generation of whole storehouse dynamically.

All contain the impurity of some in the grain of storage, impurity is the critical limitation factor that influences grain storage pest quantity sensing.Grain storage pest all is the microminiature kind mostly, in the high grain layer of difference heap, distribution is arranged all, need the number of pest sensing device can control impurity for this reason, must pile layering to the grain storage pest accurate recording at grain again, only be difficult to objectively respond different grain layer insect truths take place in the detection of grain heap surface layer.For addressing this problem, the utility model is to have proposed new technical scheme on the basis of Chinese invention patent ZL92102125.9.

The patent of invention content:

Grain worm trap checkout gear detects impurity formation principal element in the sample: the one, and the friction of slotting process and grain grain causes impurity to fall under the trap checkout gear; The 2nd, trapping pests portability small amount of impurities.For this reason, adopt technical scheme: with the pest-induced tube joint portion be a convex joint; Pest-induced tube perisporium worm trapping hole is an inclined hole, adopts probe tractive wire scheme to be used for fixing this device of traction, detects funnel and is connected with a conduit, and conduit both can pass sensor, can write down number of pest during insect process sensor, fell into collection worm bottle along conduit then; Conduit also can extend upwardly on the grain face, adopt wind-force to inhale the sample prescription case, draw the insect sample of probe trapped inside by conduit, identify that to catching pest species the wind-force dust catcher is a known technology, therefore be easy to realize, this device can be used for the grain storage pest free from admixture separately and detect, also can be assembled into grain storage pest quantity sensing probe, reduce error, improve sensitivity with amount sensor.

Compared with the prior art, beneficial effect is: under the low situation of grain heap impurity content, inclined hole shape worm trapping hole can be realized can trapping pests, can control the purpose of grain heap impurity again.Under the higher situation of grain heap impurity content, this tool inclined hole shape grain worm trap checkout gear can with the worm trash eliminator assembling of above-mentioned ZL92102125.9 patent China Oil and Food Import and Export Corporation, realize the effect of impurity in the multiple control grain heap.Particularly in large granary, general heap is high more than 6 meters, along with probe insertion silo is more and more darker, its impurity is more and more, therefore, the outstanding problem of Control of Impurities when patent of the present invention both can overcome probe conveying or work because of tractive wire traction and fixation, can be sent this device location into and be placed in for a long time grain and pile surveyed area; Realize that the layering that grain piles up under the different depth detects.Existing grain storage pest amount sensor mainly adopts infrared emission to accept diode and manufactures the optical chopper technical scheme, one sensor conduit is installed between infrared transmitting tube and adopter, can guarantee between the sensor element apart from uniformity, repeated numeration attached to causing on the sensor in the time of so both can having avoided catching insect and fall, the error that dislocation causes in the time of can avoiding sensor to install again.Adopt wind-force to inhale the sample prescription case, can draw the trapping pests sample easily and fast, both can classify catching pest species, also can avoid popping one's head in inner pile up catch insect.

Description of drawings:

Accompanying drawing is this equipments overall structure schematic diagram, and Fig. 1 is the probe tractive wire, and Fig. 2 pest-induced tube, Fig. 3 are the convex joint, and Fig. 4 is a worm trapping hole, and Fig. 5 is a funnel, and Fig. 6 is a conduit.

Embodiment:

By probe tractive wire (1) traction and fixing grain storage pest checkout gear, tractive wire can be made up of pull rope and sensor cable, form by pull rope and fluke conduit, also can form, or above-mentioned homogenous material is formed by pull rope, sensor cable and fluke conduit.At pest-induced tube (2) base portion, with cooperate greater than pest-induced tube external diameter convex joint (3), by probe delivery cannula effect convex joint, to pop one's head in to locate and send into grain heap surveyed area, extract the probe delivery cannula then out, the single-unit probe can be placed at grain heap surveyed area like this, avoid probe to cause impurity to fall into probe because of rubbing through worm trapping hole with the grain grain at grain heap course of conveying; When needing to take out probe, can will pop one's head in by probe tractive wire (1) proposes from the grain heap.Pest-induced tube (2) perisporium worm trapping hole is inclined hole (4), and movable insect can climb into along inclined hole in the grain heap, and inorganic matter impurity can not upwards be crawled into grain worm trap checkout gear along inclined hole, can avoid trapping pests to carry small amount of impurities.Convex joint (3) is uncovered to be a funnel (5) to top, and the insect of being convenient to trap falls fast, plays the trap effect.Conduit (6) is connected with funnel, and passes photoelectric sensor, is convenient to catching the number of pest record.Need to remove when being deposited in the probe collection worm bottle insect, also can adopt wind-force to inhale the sample prescription case, draw the trapping pests sample by extending to grain out-pile conduit.
