Description
Technical field
The utility model belongs to agricultural machinery technological field, and checkout gear is counted in the seeding that relates on the sower, and particularly a kind of seeding counting when being used for the sower operation also can be used for the sower seeding counter of the Performance Detection of seeding unit.
Background technology
When every seed passed through the detection sectional plane of counter successively, the sensor on the counter can detect a seed signal to the existing seeding counter that is used for sower at every turn when work; When two above seeds pass through the detection sectional plane of counter simultaneously, sensor on the counter also can only detect a seed signal at every turn, so the existing seeding counter that is used for sower exists the seeding counting that is only limited to the planter that is used for the simple grain seeding, as, the seeding counting of crop simple grain point such as corn, soybean, wheat sowing time, and can not be used for the seeding counting of the drilling machine of non-simple grain seeding, as, the weak point of the seeding counting of rare sowing time of crops such as paddy rice.
Summary of the invention
The weak point that the utility model is counted at the existing existing above-mentioned seeding that can not be used for the drilling machine of non-simple grain seeding of seeding counter that is used for sower, the sower seeding counter that provides a kind of seeding that can be used for the drilling machine of non-simple grain seeding to count.
The technical scheme that the utility model sower seeding counter adopts is finished in the following way:
Sower seeding counter comprises main frame, display and sensor unit, wherein, main frame is made up of housing and electronic circuit, the upper end of sensor unit and the sowing port of seeding unit join, sensor unit is made up of sensor stand and plurality of sensors, and sensor stand is kind of a subchannel, and the cross section of sensor stand is a rectangle, the top of sensor stand is bend, in the sensor stand, the bottom is straight way; Be provided with some parallel backguys at the sensor stand middle part along fore-and-aft direction; Each sensor all adopts photoelectric sensor, and plurality of sensors is parallel to be contained on the detection segment of sensor stand bottom side by side; With dividing plate the detection segment cross section is separated into several detected cells, the narrowest place of detected cells passage size is greater than 8mm, dividing plate adopts lighttight thin plate, causes obstruction for preventing that seed is shelved on adjacent two dividing plates, and the upper end of adjacent two dividing plates is high and low straggly; All be provided with testing circuit in each detected cells, the testing circuit of each detected cells is sent into detected seed signal in the I/O mouth of the single-chip microcomputer in the electronic circuit of main frame, by the single-chip microcomputer accumulated counts and send display to show.
During use, open the power switch on the main frame, the seeding counter is started working.Fallen earlier on the bend wall on sensor stand top by the seed flow that seeding unit is discharged, seed flow and bend wall produce the collision rear section and scatter, continue to fall.When seed flow during by the backguy district, through repeatedly scatter fully after the random collision, subregion falls, and makes two seeds reduce greatly by the probability of same detected cells simultaneously.So under the condition of the non-simple grain seeding of seeding unit, the utility model still has higher seeding counting precision.
The utility model sower seeding counter is compared with the existing seeding counter that is used for sower, has the characteristics of the seeding counting of the drilling machine that can be used for non-simple grain seeding, and has than higher accuracy of detection; The utility model sower seeding counter also can be used for the Performance Detection of seeding unit.
