Problems solved by technology

But the seed chamber of this device is arranged on the sprocket wheel at the end of the transmission chain that forms the ring, and the sprocket wheel has undertaken the dual tasks of the sprocket wheel and the seed wheel, resulting in extremely high precision requirements for the complexity of the sprocket wheel structure. High, so the cost and manufacturing requirements are greatly increased, and the failure rate remains high

Embodiment 1

[0043] Embodiment 1: refer to Figure 1-11, is a structural schematic diagram of Embodiment 1 of the present invention, a sprocket mechanism composed of a sprocket and a chain is set, and the seeding mechanism is arranged on the chain of the sprocket mechanism, and the described seeding mechanism is an array of rows on the chain. Seed mouth or on-demand nozzle, the lower chain of the sprocket mechanism is provided with a horizontal section, and at least two or more seeding mechanisms are arranged on the horizontal section, and more than two seeding mechanisms perform seeding simultaneously or sequentially during travel , prolong the contact time of a single seeding mechanism with the ground, and at the same time, set a seed-taking mechanism independent of the sprocket in the sprocket mechanism, and throw seeds to the seed-setting mechanism arranged on the chain through the independent seed-taking mechanism.

[0044] In this embodiment, the specific crawler-type high-speed sowi...

Embodiment 2

[0052] Embodiment 2: refer to Figure 12 , is a structural schematic diagram of Embodiment 2 of the present invention. Compared with Embodiment 1, the difference of this embodiment is that the described seed wheel 71 is an endless rubber belt, and the described seed-taking hole 72 is arranged at the conveying On the belt-shaped body, a seed picker 78 is arranged in the seed-taking hole 72. The seed picker 78 is a seed spoon, and the seed spoon is installed in the seed-taking hole through a pin shaft and is provided with a return spring and a trigger. Fork, is provided with trigger 79 on the side of seed-taking mechanism 7, and this trigger 79 is the bump on the kind-taking type hole 72 on the kind-taking wheel 71 that takes kind or throws the bump on the traveling route, on the kind-taking wheel 71 On the route of taking or throwing seeds in the seed-taking hole 72, when the trigger swing lever touches the bump, the seed picker 78 changes state to realize taking or throwing se...

Embodiment 3

[0053] Embodiment 3: refer to Figure 13-14 , is a structural schematic diagram of Embodiment 3 of the present invention. Compared with Embodiments 1 and 2, the difference of this embodiment is that the described seed wheel 71 is an annular rubber belt, and the inner side of the rubber belt is provided with a transverse concave Groove can not only ensure a certain thickness of the rubber belt, but also can install the seed picking mechanism, and can adjust the expansion and contraction due to the deformation of the rubber belt during operation. The rubber belt is provided with a seed picker 78, which is a Cylindrical body, the cylindrical body is connected to the rubber belt through a pin shaft and can rotate. At the same time, the cylindrical body is provided with a return spring and a trigger swing lever. The described seed-taking hole 72 is arranged on the cylindrical body. Side is provided with trigger 79, and this trigger 79 is the bump on the seed-taking type hole 72 on ...

Abstract

The invention discloses a crawler-type high-speed seeding or seed-metering method and device and a seeding machine formed by the crawler-type high-speed seeding or seed-metering method and device. A seed taking mechanism independent of a chain wheel is arranged in a chain wheel mechanism, and seeds are fed to a seed-metering mechanism arranged on a chain through the independent seed taking mechanism. According to the crawler-type high-speed seeding or seed-metering method and device and the seeding machine formed by the crawler-type high-speed seeding or seed-metering method and device, seed metering is carried out simultaneously or sequentially through a plurality of seed-metering holes formed in the transmission chain, so that the contact time of a single seed-metering mechanism and the ground is prolonged, seeds completely fall into seed holes, high-speed seed metering or seeding is realized, the seed metering or seeding quality is ensured, and particularly, the functions of the seed-metering mechanism and the chain wheel are respectively set. The chain wheel is simple and more resistant to the severe environment, the seed-metering mechanism is arranged in a relatively stable environment, the precision and safety of the seed-metering mechanism are guaranteed, high-speed seeding can be achieved, the seeding or seed metering quality is guaranteed, and the capability of the seeding or seed-metering device to adapt to the severe environment is greatly improved.

Description

technical field [0001] The invention relates to a method for sowing or sorting seeds, its device and the seeder formed therefrom, in particular to a crawler-type high-speed seeding or seed sorting method, its device and the seeder formed therefrom. Background technique [0002] With the advancement of crop planting technology, precision sowing and precision on-demand technology have been applied and promoted. However, the current sowing machinery, especially precision sowing or seeding machinery, generally uses low-speed sowing, which affects the operation due to the low sowing speed. efficiency. [0003] For example, the current perforating devices on the film in the sowing process of crops are all roller-type or four-bar linkages for perforating and sowing. Since the contact time between the seeding part and the ground is extremely short, it is difficult for the seeds to effectively fall into the seed hole, resulting in the operating speed of the machine tool. cannot be i...
