Mechanical planter seed granule falling blocking audible-visual alarm apparatus

Abstract

The invention discloses a mechanical planter seed granule falling blocking audible-visual alarm apparatus. The mechanical planter seed granule falling blocking audible-visual alarm apparatus comprises a 12V direct-current power source, an infrared ray emission circuit, an infrared signal receiving circuit, a negative pulse forming circuit, a voltage comparing circuit, a high electrical level power amplification and audible-visual alarm circuit; and in the voltage comparing circuit, the model of an adopted operational amplifier IC1 is <mu>A741. The mechanical planter seed granule falling blocking audible-visual alarm apparatus is capable of ensuring crop sowing quality, and is designed for farmers. The mechanical planter seed granule falling blocking audible-visual alarm apparatus can be used for monitoring falling situations of seed granules in a pipeline constantly; once blocking is caused in seed granule falling process, the mechanical planter seed granule falling blocking audible-visual alarm apparatus is capable of alerting operation staff to perform corresponding dredging measures in time, so that large area miss-seeding is avoided, crop sowing quality and farming area working efficiency are increased effectively.

Description

technical field [0001] The invention belongs to the fields of electronic technology and agricultural production, and relates to an audible and visual alarm device for seed drop blockage of a mechanical seeder. Background technique [0002] The common crop sowing methods are: sowing, drilling, hole sowing and precision sowing. The so-called drill sowing: the seeds are sown into strips according to the row spacing, sowing depth and sowing amount required by the crops. Because drill sowing is conducive to ventilation and light transmission during the growth period of crops, it is convenient for field fertilization, weeding and other operations management, so drill sowing technology is widely used in sowing wheat, corn, beans and other crops. [0003] When the ordinary seed drill is sowing, because the seeds are mixed with debris such as grass stalks, other seeds or stones, it is easy to cause blockage in the pipeline during the falling of the seeds. Because the seeds to be br...

Problems solved by technology

[0003] When the ordinary seed drill is sowing, because the seeds are mixed with debris such as grass stalks, other seeds or stones, it is easy to cause blockage in the pipeline during the falling of the seeds.

Because the seeds to be broadcast must be covered with soil, once the seeds are blocked during the sowing period, it is difficult for the operator to find out the leakage of the seeds in time. Lead to lack of seedlings and broken ridges of crops, affecting crop yield and harvest
