Description
Technical Field
The utility model relates to a seed count field among the agroforestry articles for use especially relates to an infrared several appearance.
Background
The existing seed counting is usually carried out in a manual counting mode, the counting mode is long in time consumption, and when the sample inspection amount is large, errors are easy to occur. Also there is the mode that adopts seed number board to carry out the number on the market, but number board also mainly relies on manual operation, if when carrying out extensive examination to hundreds of strains, can consume a large amount of manual works, and the cost is higher, and efficiency is not high, makes mistakes easily moreover. In addition, there are also devices such as automatic particle counter with higher automation in the market, and when counting particles by using the existing particle counter, counting errors are often caused because seeds pass through the counting device at the same time.
There are also devices and apparatuses for counting seeds in published patent documents, for example, chinese patent with publication number CN 106275640B discloses a planar laser counting device including a semiconductor laser, an optical lens group, a counting box and a photoelectric receiver. A point light source emitted by the semiconductor laser forms a one-dimensional line light source through the optical lens group, and the photoelectric receiver performs plane omnibearing dead-angle-free counting. The counting principle is that when the particles pass through a laser plane (one-dimensional line light source) in the particle counting chamber, the line light source is shielded, the photoelectric receiver detects the signal change of the line light source, and the change signal is processed to determine the number of the passing particles and count and record the number of the passing particles. Theoretically, this scheme can take notes all quantity through the seed of laser plane, however, to non-circular seed, its transversely through the laser plane and the vertical line source size that shelters from through the laser plane are different, can lead to the count deviation, consequently, when adopting this kind of counting mode to count to non-circular seed, can't ensure the accuracy of count result.

The utility model aims at providing an infrared several appearance to solve the problem that prior art exists, utilize the conveyer belt to forward the particulate matter to the feed inlet of vertical passageway, under the carry effect of the recess of list setting on the conveyer belt, the particulate matter counts in interval gets into vertical passageway one by one, can avoid many particulate matters to drop simultaneously and counting device can't accurately count the count deviation that causes, improves the count precision.
In order to make the above objects, features and advantages of the present invention more comprehensible, the present invention is described in detail with reference to the accompanying drawings and the detailed description.
As shown in fig. 1, the utility model provides an infrared particle counter, which can be used for counting particles 10 (including seeds, capsules, tablets, particles, buttons, etc.), comprising a conveyer belt 1 and a vertical channel 2 arranged at the discharge end of the conveyer belt 1, wherein the feed inlet of the vertical channel 2 is positioned below the discharge end, because the rotation direction of the conveyer belt 1 is towards the vertical channel 2, the particles 10 on the conveyer belt 1 can be conveyed to the feed inlet of the vertical channel 2, and the particles 10 can fall into the vertical channel 2 under the action of the gravity of the particles 10 after being separated from the conveyer belt 1; in order to ensure smooth dropping of the particulate matter 10, the feed port of the vertical channel 2 may be provided in an open type. The vertical channel 2 can be of a tubular or chute configuration in order to guide the particles 10 to a counting device for counting. A plurality of single-row grooves 11 for carrying single particles 10 are arranged on the conveying belt 1 along the conveying direction, and the grooves 11 can be formed on the conveying belt 1 by direct processing or a device with the grooves 11 is arranged on the conveying belt 1. The shapes of different kinds of particles 10 are different from each other, and the shape of the groove 11 is adapted to the shape of the particle 10, and may be hemispherical, rectangular parallelepiped, or the like, but it should be noted that the same kind of particles 10 are targeted when counting particles each time. Every recess 11 is used for carrying single granule 10, and the purpose that the single file set up can carry granule 10 interval one by one to vertical passageway 2, after recess 11 aims at vertical passageway 2's feed inlet one by one, can interval one by one fall granule 10 in by vertical passageway 2. It should be noted that recess 11 is as far as possible with adjacent recess 11 in close contact with or be provided with flexible connection structure to can not form the clearance that holds particulate matter 10 as far as possible, in fact, if there is particulate matter 10 in the clearance of recess 11, owing to still have the interval with the particulate matter 10 in the recess 11 around, can not influence the utility model discloses the realization of effect after particulate matter 10 falls into vertical passageway 2. In addition, there is no space for carrying the particulate matter 10 on both sides of the conveying direction of the grooves 11, that is, the particulate matter 10 falling on the surface of the conveyor belt 1 is scattered to the outside of the conveyor belt 1 except into the grooves 11 (or partially into the gaps of the adjacent grooves 11). At this time, the conveyor belt 1 is finally formed to convey a single line of the particulate matter 10 arranged at intervals. Be provided with collection device 6 in vertical passageway 2's discharge gate department, set up the through-hole that transversely link up on vertical passageway 2, the both ends of through-hole are provided with infrared emitter 3 and the infrared inductor 4 that are used for the count respectively, 4 electric connection of infrared inductor have photoelectric counter 5, infrared emitter 3 launches the infrared light, infrared inductor 4 detects infrared light beam, make when the vertical whereabouts of particulate matter 10 passes through, the infrared ray just is blockked, photoelectric conversion is the signal of telecommunication this moment, realize once counting through photoelectric counter 5.
