Fig. 2 is the functional block diagram of the utility model control circuit;
The flow chart that Fig. 3 detects for the utility model grain moisture.
Embodiment
The utility model is described in further detail below in conjunction with accompanying drawing.
As shown in Figure 1, a kind of combine grain moisture detects sampler, it comprises support, be installed on grain moisture on the support measure storehouse 1, be located at grain moisture measure the cereal of 1 lower end, storehouse upgrade door 5, control cereal upgrade out-of-work travel switches 6 of drive unit, accessory drive that door 5 rotates, be located at grain moisture measure the photo-electric of 1 upper end, storehouse buy securities with all one's capital sensor 7, and with drive unit, travel switch 6, the photo-electric control circuit that sensor 7 is connected of buying securities with all one's capital.
Wherein, drive unit comprises that DC speed-reducing 2 reaches transmission mechanisms that are connected and the rotation of motor output shaft is converted to 5 swings of cereal renewal door with the output shaft of DC speed-reducing 2.This transmission mechanism specifically comprises a crank that is connected with motor output shaft 3, the connecting rod 4 that is connected with crank 3, and the rocking bar 8 that is connected with connecting rod 4, and cereal renewal 5 is connected with rocking bar 8.When above-mentioned DC speed-reducing 2 is revolved three-sixth turn, drive renewal door rotation 60 degree, make the rotation of motor can not cause damage equipment by above-mentioned transmission mechanism.This grain moisture is measured storehouse 1 and is vertically hung on the support, support is fixed on the mouth of putting out cereal of combine elevator, the trip switch 6 is located at grain moisture and is measured on another bottom sides of storehouse 1 phase countershaft, when cereal renewal door 5 is run into travel switch 6, travel switch 6 sends signal to single-chip microcomputer, and Single-chip Controlling DC speed-reducing 2 shuts down.
This control circuit comprises single-chip microcomputer 9 and relay 10, and single-chip microcomputer 9 connects travel switches 6 and the photo-electric sensor 7 of buying securities with all one's capital, and single-chip microcomputer 9 is connected with DC speed-reducing 2 by relay 10.
One end of this cereal renewal door 5 is connected at the rotating shaft on 1 bottom sides of grain moisture measurement storehouse, and the other end that cereal upgrades door 5 is a free end, and this rotating shaft is connected to drive unit.Cereal upgrades door 5 and is in grain moisture measurement 1 below, storehouse, is used to stop the cereal of not surveying moisture content to flow out or discharge and has surveyed cereal.
When carrying out moisture measurement, realize according to following step:
Step 1: start DC speed-reducing 2 earlier, motor is carried out positive transfer to test and counter-rotating test, and the running of beginning DC speed-reducing 2;
Step 2: whether single-chip microcomputer 9 detects travel switches 6 and is pressed, if be not pressed then motor is rotated further, if be pressed then motor stops operating, and carries out next step;
Step 3: cereal flows into grain moisture and measures storehouse 1, and when cereal was full of grain moisture and measures storehouse 1, the photo-electric that grain moisture is measured 1 upper end, the storehouse sensor 7 of buying securities with all one's capital detected, and sends signal to single-chip microcomputer 9;
Step 4: grain moisture is measured and after the order of single-chip microcomputer 9 is received in storehouse 1 moisture of cereal is measured;
Step 5: single-chip microcomputer 9 is given an order and is controlled DC speed-reducing 2 entrys into service, opens cereal and upgrades door 5, has surveyed the cereal of moisture thereby discharge in the grain moisture measurement storehouse 1, and has got back to step 2, so finishes a measurement circulation.
Above-mentioned cereal renewal speed is determined by grain header harvesting speed, sampler can be full of grain moisture measurement storehouse 1 in 30 seconds during the combine normal operation, the cereal emptying time is 2 seconds in the grain moisture measurement storehouse 1, receive that at control circuit photo-electric buys securities with all one's capital behind the signal of sensor 7, grain moisture is measured storehouse 1 and is begun to measure moisture, the accessory drive of again signal being given an order after measurement is finished is opened cereal and is upgraded door 5, and owing to the time of cereal emptying is very fast, so 2 need of DC speed-reducing rotate a circle, promptly 360 degree can be measured grain moisture the whole emptyings of cereal in the storehouse 1.
