Embodiment Construction

[0069] Below in conjunction with accompanying drawing, structural principle and working principle of the present invention are specifically described:

[0070] see Figure 1-Figure 4 , figure 1 It is a structural schematic diagram of a sowing device according to an embodiment of the present invention, figure 2 for figure 1 left view of image 3 for figure 1 bottom view of Figure 4 for figure 1 top view. The dual-motor real-time reseeding adjustment sowing device of the present invention can be hooked on agricultural machinery such as a seeder and a tractor, and includes: a frame, which can be set as a left-right symmetrical first frame 11 and a second frame 3, the second frame The first frame 11 and the second frame 3 are respectively connected with the support 9 of the connection mechanism and the seed protection plate 8 of the secondary seeding mechanism, so as to keep the integrated connection of the core mechanism in the whole sowing device. At the same time, the...

Abstract

A double-motor real-time replanting adjustment seeding device and method are disclosed. The device is in hook connection with a seeding machine, and includes a machine frame, a primary seed charge mechanism, a connecting mechanism, a secondary seed charge mechanism, and a ditching mechanism; the primary seed charge mechanism includes a first motor, an air suction precision seed metering device anda miss-seeding sensor, wherein the miss-seeding sensor judges whether a seeding hole position of the air suction precision seed metering device is a single seed or not, and a seed taking disc of theair suction precision seed metering device is controlled to rotate by the first motor to ensure single-seed seeding and no seed leakage; th connecting mechanism is connected with the primary seed charge mechanism and the secondary seed charge mechanism; the secondary seeding mechanism comprises a second motor and a seeding disc, wherein the second motor controls the linear velocity of the seedingdisc and the traveling speed of the seeding machine to be to be opposite in direction and equal in speed value, so as to ensure zero speed seeding when seeds fall; and wherein, the maximum instantaneous rotation speed of the seed taking disc is greater than the instantaneous rotation speed of the seeding disc to ensure the seeding accuracy. The invention also discloses the double-motor real-time replanting adjustment seeding method of the device.

Description

technical field [0001] The invention relates to an intelligent precision sowing technology, in particular to an ultra-precise dual-motor real-time reseeding and regulating sowing device and method. Background technique [0002] Intelligent precision seeding is an effective way to increase planting yield and has become the main development trend of seeding today. Precision sowing is based on agronomic requirements, and seeds are sown into the soil in a reasonable quantity and at a suitable location. The two key indicators of precision sowing technology are the amount and location of missed sowing. At present, precision seeding technology has bottlenecks in the control of missed seeding amount and seeding position. [0003] Taking maize as an example, the agronomically optimized sowing quantity is single seed sowing. Existing precision seed metering devices are mainly air suction type, finger clip type, spoon wheel type, etc., which can basically achieve single seed sowing, ...
