Description
One, technical field
The utility model relates to a kind of novel pipeline obstruction alarm that is used in time reporting combined seed and fertilizer drill fertilizer seed tube road stopping state.
Two, background technology
Drag by tractor during the ferti-seeding machine operation that is widely used in the rural area.The top of combined seed and fertilizer drill is provided with receptacle and seed-box.The outlet at bottom place of receptacle and seed-box is equipped with several fertilizer pipes and seed pipe according to row spacing, is called for short fertilizer seed tube.In the process of advancing, granular fertilizer falls into field through fertilizer seed tube by the mechanism that is connected on the fertilizer kind axle respectively equably with seed.During normal operation, because the effect of the pipe wing and baffle plate, earth can not enter fertilizer seed tube.When tractor drive seeder retreated, the fertilizer seed tube bottom entered earth easily.After this tractor readvances, and the earth in the fertilizer seed tube is trapped in the pipe sometimes, and pipeline will stop up.Sometimes, weeds or other article are wrapped in the bottom of fertilizer seed tube, also can make fertilizer or seed fall into field and cause line clogging.After the line clogging, the fertilizer or the seed of discharging from receptacle or seed-box will be deposited in the fertilizer seed tube.When tractor driver finds latch up phenomenon is arranged, often stopped up for a long time the very long distance of having travelled.Seek the starting point of this ridge broadcast leakage again and carry out after-culture or supplementary fertilizer this moment, and the energy that then will cost a lot of money consumes for a long time.Peasant brother usually complains incessantly for this reason.
I succeed in developing and declare a kind of line clogging alarm (application number is 03284240.6) of patent, am to utilize the principle of earth conduction to realize sound and light alarm.Its effective alarm rate during for the earth blocking pipe can reach 100%.Yet in some cases, when line clogging is caused in the bottom that weeds or other article are wrapped in fertilizer seed tube, can often fail to report.This is a deficiency of its line clogging alarm, moreover another problem of this line clogging alarm is when line clogging, and it can not be reported is for which line clogging, and this makes troubles for rapidly removing faults.
Three, utility model content
At above-mentioned situation, the purpose of the utility model just provides a kind of novel pipeline obstruction alarm that can overcome above deficiency, use photovoltaic principals, the problem of in time and accurately reporting to the police in the time of can effectively solving line clogging, the technical scheme of its solution is that this alarm is made up of clogging sensor and warning device.Clogging sensor adopts photovoltaic principals, forms by luminescent device and photosensitive device, their respectively radially relative fixed bottom the fertilizer seed tube.When pipeline was not blocked, the light that luminescent device sends can shine on the sensitive surface of photosensitive device; When pipeline was blocked, the light that luminescent device sends was blocked, and the light intensity that the sensitive surface of photosensitive device receives can weaken greatly.The variation that the photosensitive device sensitive surface receives light intensity can cause its output signal to change; Warning device is made up of housing and inner sound light alarming circuit, and sound light alarming circuit is made of circuit board and continuous connection terminal, microphone device and power supply thereof.Circuit board is to constitute by being installed in triode on the insulating gel plank, resistance, light emitting diode, relay etc.Reliable warning when the utility model can be realized All Media stopped up can also report which the pipeline that takes place to stop up is, accurate rapidly removing faults, and dependable performance, simple in structure, with low cost, application prospect is very wide.
