Abstract
The utility model discloses a seeds spacing detecting transducer, comprising a seeds spacing tube, wherein, a seeds spacing mechanism, an adjustable seeds detecting channel and a lower interference of the seeds spacing tube are respectively arranged under an upper interference of the seeds spacing tube; the adjustable seeds detecting channel is provided with a pair of infrared emission/receiving elements which are taken as detecting elements. The utility model adopts one beam of infrared ray to precisely detect the passing situation of seeds, and is applicable to crop seeds of a variety of sizes.
Description
Technical field
The utility model relates to a kind of precision metering device detecting sensor.
Background technology
During the sower farm work, because a variety of causes such as defective that the influence of farm environment, the quality of seed, operating personnel's carelessness and sower itself exist, often occur stifled kind, leak kind, broadcast situations such as speed is undesired, make phenomenons such as kind of a broadcast leakage, disconnected bar, uneven sowing be even, influence crop yield.And very difficult observation of these phenomenon naked eyes obtains.For guaranteeing the work quality of sower, need seed actual in the sowing process to detect by situation.In the performance evaluation experiment of seeding unit, the detection of seeding situation is even more important.Seeding situation accuracy of detection fundamentally is decided by the precision of seed by detecting sensor, needs the detecting sensor of a kind of precision of design.At present the seeding detecting sensor mainly adopts infrared rays to detect, as seed by the time blocking infrared rays produce signal.But there are some problems in traditional sensor on version: circle is adopted in the sense channel cross section more, the bad layout of detecting element, the excessive then omission easily of area, too small stifled easily again kind of area; Adopt one to two bundle infrared detection, though simple in structure, the loss height; Adopt some new and high technologies such as image recognition, though precision height complex structure is realized difficulty, cost is higher; Can not adjust easily to adapt to different crop seeds according to the sensor of seed sizes design in addition.
Summary of the invention
For solving the above-mentioned technical problem of existing seeding detecting sensor, the utility model provide a kind of simple in structure, precision is high, the convenient precision metering device detecting sensor of adjusting seed sense channel width.
The technical scheme that the utility model solves the problems of the technologies described above is: comprise discharging tube, the interface below is provided with seed queueing mechanism, adjustable seed sense channel, discharging tube lower interface successively on the discharging tube, and the adjustable seed sense channel is provided with a pair of infrared emission/receiving element as detecting element.
In the above-mentioned precision metering device detecting sensor, described seed queueing mechanism is by last queuing V-shaped groove, the V-shaped groove of lining up is formed down, on line up V-shaped groove, the V-shaped groove of lining up shifts to install relatively down.
In the above-mentioned precision metering device detecting sensor, described adjustable seed sense channel is located at the below of seed queueing mechanism, is made up of two slide blocks, discharging tube housing.
Technique effect of the present utility model is: 1) adopt the seed queuing, realized seed detect before preliminary treatment, avoided to a great extent many seeds simultaneously by the time omission situation that causes; 2) only adopt a branch of infrared beam promptly to realize accurate detection, simplified mechanism, reduced cost, improved reliability; 3) adopted adjustable long rectangle sense channel cross section, promptly guaranteed accuracy of detection,, made sensor have versatility again applicable to different seeds; 4) the discharging tube mounting interface of employing circular cross-section can be installed on the discharging tube easily.

Embodiment
Referring to Fig. 1, the utility model comprises discharging tube 1, interface 6 belows are provided with seed queueing mechanism, adjustable seed sense channel, discharging tube lower interface 10 successively on the discharging tube, and the adjustable seed sense channel is provided with a pair of infrared emission/receiving element 9 as detecting element.Described seed queueing mechanism is by last queuing V-shaped groove 2, the V-shaped groove 3 of lining up is formed down, on line up V-shaped groove 2, the V-shaped groove 3 of lining up shifts to install relatively down; The adjustable seed sense channel is located at the below of seed queueing mechanism, is made up of slide block 4, slide block 7, discharging tube housing, and the spacing of slide block 4, slide block 7 is adjusted by regulating bolt 5, forms suitable sense channel width.
The use of sensor: opening power, when seeding unit was worked, the situation of passing through that sensor is about to seed converted the level pulse signal to.
The last queuing V-shaped groove 2 and the V-shaped groove 3 of lining up down make seed form single-row queuing before entering sense channel, avoid taking place many seeds simultaneously by the situation of infrared light beam, guarantee the precision that detects.
Referring to Fig. 3, be seed sense channel 93 by seeding kind 1 shell, slide block 4 and slide block 7 formed adjustable spaces.Detecting element is made up of infrared transmitting tube 91 and infrared receiving tube 92, forms infrared beam 94 at the sense channel kernel of section during work, and when seed passed through, the blocking infrared beam produced signal.The cross sectional shape of the long rectangle of variable-width can limit the activity of seed at width, guarantees that seed by infrared beam, can increase by area again in the longitudinal direction, prevents stifled kind.Adjustable width is applicable to the seed of different size simultaneously.
