Rapeseed spiral stepping reseeding system

Abstract

The invention belongs to the technical field of agricultural machinery, and particularly relates to a solenoid-type step rapeseed reseeding system. The system mainly comprises a solenoid-type reseeding device and a step reseeding control module, wherein the solenoid-type reseeding device mainly comprises a seed discharging roller, a spiral pipeline, a cylindrical seed box, an annular hole baffle, an end cap, a seed discharging shaft, a seed guide pipe and the like; the step reseeding control module comprises a direct-current step motor, an input circuit, a pulse generation control circuit, a counter, a signal circuit and a drive circuit. When a control system receives seeding absence signals, the step motor is started to drive the solenoid-type reseeding device to rotate at a corresponding angle according to the number of pulses of the seeding absence signals, so that reseeding is realized. The solenoid-type step rapeseed reseeding system is used in cooperation with a seeding absence real-time detection method of a precise rapeseed discharging device, reseeding can be conducted timely and accurately, the miss-seeding problem of a precise rapeseed sowing machine and the problems that shaped holes of a mechanical reseeding device are blocked easily and the breakage rate of seeds is high are solved, the labor cost of reseeding later is reduced and the production efficiency and the sowing quality are improved.

Description

technical field [0001] The invention belongs to the technical field of agricultural machinery, and in particular relates to a rapeseed spiral tube type step-by-step replanting system. Background technique [0002] The pneumatic rapeseed precision combined direct seeding machine has the advantages of saving seed fertilizer, high operating efficiency, and good seedling emergence effect. The precision seed metering device is the core component of the direct seeding machine. On the one hand, due to the complex working environment in the field and defects such as lack of seed in the seed box, blockage of the seed delivery pipe, and failure of the seed meter during the working process of the precision seeder, one or several rows will have "broken strips" and missed sowing. phenomenon, seriously affecting crop yield; on the other hand, the optimization and improvement of precision seed metering performance is still in the research stage, and it is difficult to completely avoid miss...

Problems solved by technology

However, rapeseed is a small-sized seed, which is light in weight, easy to be damaged, and has a high oil yield rate, which is easy to cause clogging of the molding hole. If a pneumatic rapeseed reseeding device is used for reseeding, the complexity of the structural components will increase and the cost will increase.

[0004] In view of the above problems, the present invention proposes a rapeseed spiral step-by-step reseeding system, which is used in conjunction with the developed real-time detection method for missed sowing of the rapeseed precision metering device. The spiral reseeding device makes full use of the flow of rapeseed With the help of gravity automatic seed filling, spiral tube seed protection, seed transfer and even seed injection, it solves the problems of mechanical hole blockage and high seed damage rate caused by mechanical reseeding devices. At the same time, the step-by-step reseeding drive system can The amount of seeds can be controlled, and it can be replanted in a timely and accurate manner. It has the characteristics of simple structure and low cost.
