Seeding device for simulating field vibration working environment in laboratory

Abstract

The invention discloses a seeding device for simulating a field vibration working environment in a laboratory. The seeding device comprises a vibration seed discharging part on the upper portion and aseed receiving part on the lower portion, wherein the vibration seed discharging part is arranged on a frame, the seed receiving part is arranged on a supporting frame, the top of the supporting frame is provided with a guide rail, the bottom of the frame is provided with rollers capable of rolling in the guide rail, and the vibration seed discharging part comprises a seed discharging device anda crank connecting rod mechanism enabling the seed discharging device to irregularly vibrate; and the seed receiving part comprises a seed discharging pipe and a conveyer belt in a seed discharging pipe discharge port. The seeding device for simulating the field vibration working environment in the laboratory has the advantages that the seeding device can simulate seed discharging under the fieldvibration working environment to replace the static seed discharging working of a seed discharging device in an existing seeding test bed so that better test data of the field seeding working can be obtained, and a solid foundation is laid for improving the performance of existing products, creating good test conditions and providing reliable design bases. The seeding test bed has the advantages that the structure is simple, the use is convenient, and the functions are reliable.

Description

technical field [0001] The invention relates to the technical field of agricultural machinery, in particular to a sowing device in a laboratory simulated field vibration operation environment. Background technique [0002] Precision seeding is one of the key technologies to increase agricultural production and reduce agricultural production costs, and the performance of the seed meter is the main factor affecting the seeding quality of precision seeders. In recent years, with the rapid development of domestic seeding machinery, researchers have begun to carry out indoor test bench seed metering devices, artificially manufacturing various working conditions, in order not to be restricted by the complex environment in the field, but the sowing test bench successfully developed so far Most of them are in the static seeding form of the seed metering device, which cannot meet the requirements of the seed metering device in the vibration environment in the field. Therefore, it is ...

In recent years, with the rapid development of domestic seeding machinery, researchers have begun to carry out indoor test bench seed metering devices, artificially manufacturing various working conditions, in order not to be restricted by the complex environment in the field, but the sowing test bench successfully developed so far Most of them are in the static seeding form of the seed metering device, which cannot meet the requirements of the seed metering device in the vibration environment in the field. Therefore, it is necessary to design a sowing test bench that can simulate the field vibration operating environment in order to obtain better field sowing The test data of operation effect lay a solid foundation for improving the performance of existing products, creating good test conditions and providing reliable design basis
