The invention relates to multifunctional precise seeding units. The multifunctional precise seeding units comprise empty box detection modules, precise seeding modules and flow detection modules whichare connected sequentially and respectively, and unit controllers and an upper computer which are connected with the empty box detection modules, the precise seeding modules and the flow detection modules, wherein the unit controllers are arranged on side surfaces of the precise seeding modules, the unit controllers are connected with the empty box detection modules to receive empty box warning signals transmitted by the empty box detection modules and to transmit the empty box warning signals to the upper computer so that seed adding signals can be sent, the unit controllers are connected with the precise seeding modules to transmit working parameter information to the precise seeding modules, the unit controllers are connected with the flow detection modules to receive actual flow datatransmitted by the flow detection modules and to compare the actual flow data and a set flow so that working parameters of the precise seeding modules can be adjusted, closed-loop control is achieved,and precise seeding is achieved. By means of the multifunctional precise seeding units, precise seeding can be conducted, and the amount of residual seeds can be monitored, so that automation and multi-functionalization of a seeding process are effectively improved, and variable seeding and precise seeding are achieved.
Description
technical field [0001] The invention relates to a technique in the field of agricultural equipment, in particular to a multifunctional precision seeding unit. Background technique [0002] Precision sowing is an important part of precision agriculture, and the adjustment of the speed and opening of the grooved wheel is an important means to achieve precision sowing. The sowing speed of traditional sowing machinery is adjusted through the output shaft speed adjustment. The sowing speed of all sowing units is the same, which makes it difficult to achieve precise sowing and affects the yield. The seeder in the prior art cannot realize accurate sowing of a single unit at different seeding speeds, and cannot monitor the remaining amount of seeds. Contents of the invention [0003] Aiming at the above-mentioned deficiencies in the prior art, the present invention proposes a multi-functional precision sowing unit capable of precision sowing and monitoring the remaining amount of...
