Abstract
The invention relates to a grain seeder blockage prompter. The grain seeder blockage prompter consists of a 9-volt direct-current power supply, an infrared emitting and infrared signal receiving circuit, a negative pulse forming circuit, a level conversion circuit, a stable circuit and a prompt indicating circuit, and is characterized in that: an integrated circuit in the stable circuit is a 555 time-base circuit. The grain seeder blockage prompter used for grain row seeding is designed for farmers in order to ensure the grain seeding quality. The prompter can monitor the falling condition of grains in a pipe and timely prompts an operator to take a corresponding measure to dredge the pipe once the pipe is blocked by seeds, so the phenomenon of large area of seeding leakage is avoided, and the grain seeding quality and the working efficiency of the field are effectively improved.
Description
Technical field
The invention belongs to electronic technology and agricultural production, is to stop up reminiscences about a kind of grain drill.
Background technology
Modes such as type of seeding commonly used is broadcasted sowing, drilling, bunch planting and precise sowing.So-called drilling: exactly seed line-spacing, depth of planting and the amount of broadcasting on request at the slivering row.Crops are ventilated at growing period, printing opacity because drilling helps, and task management such as be convenient to field fertilization, hoe up weeds is so the drilling technology is widely used in the sowing of crops such as wheat, millet.
Electronic surveillance device on the modern large-scale seeder generally is made up of sensor, conversion line and signal display apparatus.Sensor adopts photoelectric component more, comprising: visible light and infrared light.When seed passed through the kind subchannel of sensor, the blocking light beam made photoelectric tube send signal, and expression has seed to pass through.When a certain row of broadcasting breaks down, when no seed passes through, promptly show the number of this row on the bridge instrumentation dish, and send seed and stop up alarm sound.
Regular drill planter owing to mix foreign material such as careless bar, other seeds or stone are arranged in the seed, is easy to cause in kind of the grain dropping process and in pipeline, stops up at seeding time.Because of the kind grain that broadcasts all is coated with earth, in case taking place, stops up kind of a grain, and the sowing personnel are difficult in time find the broadcast leakage phenomenon, and when where broadcast leakage has no way of finding out about it and searches, and inconvenience is in time remedied, and finally can cause the crop disconnected ridge that is short of seedling, and influences output and harvest.
The present invention research is in order to guarantee seeding quality, and a kind of sowing machine grain that is used for the crop drilling that designs for wide farmers stops up alarm set.Had this prompting can keep watch on constantly kind of grain in ducted whereabouts situation; In case planting grain stops up in the pipeline that falls; Alarm set can in time remind operating personnel to take the measure of dredging accordingly; The phenomenon of having stopped the large tracts of land broadcast leakage takes place, and has improved seeding quality and the work efficiency of crops effectively.
Below specify this grain drill and stop up the correlation technique that reminiscences relates in manufacturing process.
Summary of the invention
Goal of the invention and beneficial effect: the present invention research is in order to guarantee the seeding quality of crop, and a kind of sowing machine grain that is used for the crops drilling that designs for wide farmers stops up alarm set.This reminiscences can keep watch on constantly kind of grain in ducted whereabouts situation; In case planting grain stops up in the pipeline that falls; Alarm set can in time remind operating personnel to take the measure of dredging accordingly; Thereby the phenomenon of having stopped the large tracts of land broadcast leakage takes place, and has improved the seeding quality of crop and the work efficiency in field effectively.
The circuit working principle: this reminiscences adopts infrared ray principle to convert the whereabouts situation of pipeline two-story valley species grain to electric signal and controls hummer and remind sounding.Infrared light emission pipe D1 and photosensitive receiving tube D2 faced be installed in kind of the grain whereabouts pipeline, the infrared light that infraluminescence diode D1 is sent just in time is radiated on the photosensitive receiving tube D2.When cereal kind grain in pipeline during normal descend, infrared light just by kind of grain blocking off and on, makes the continuous negative pulse of negative pole a point generation of infraluminescence diode D1 pipe; And, electrochemical capacitor C2 can not be charged, b point voltage approaching zero through the positive pole that electrochemical capacitor C1 is coupled to electrochemical capacitor C2; Thereby 2 pin of 555 time base circuits are low level, and simultaneously owing to the effect of positive-negative-positive silicon triode BG1, the voltage that needs only on the electrochemical capacitor C2 is zero; So, electrochemical capacitor C3 can not be recharged yet, otherwise positive-negative-positive silicon triode BG1 conducting; Electrochemical capacitor C3 will be discharged, and 2 pin of such 555 time base circuits and 6 pin all are low level, the 3 pin output high level of 555 time base circuits; Make hummer Y not have electricity and do not work, at this moment light emitting diode D3 will be lighted.
In case it is blocked in pipeline that kind of grain takes place, cereal kind grain will no longer fall, thereby the infrared ray that infraluminescence diode D1 is sent is radiated on the photodiode D2 all the time; The a point voltage just is a low level all the time like this, and because of it is a direct current signal, it can not arrive the b point through electrochemical capacitor C1 again; So electrochemical capacitor C2 begins charging; Follow electrolysis appearance C3 and also charge along with the charging of electrochemical capacitor C2, the voltage on very fast electrochemical capacitor C2, the electrochemical capacitor C3 just reaches the turnover voltage of 555 time base circuits, and 2 pin of 555 time base circuits and 6 pin become high level; 555 time base circuits reset; 3 pin output low levels of 555 time base circuits, thus hummer Y is sounded a buzzer, and red light emitting diodes D3 extinguishes because of dead electricity.
