Bevel gear transmission driving type corn multi-row simultaneous sowing precision seed sowing device

Abstract

The invention discloses a bevel gear transmission driving type corn multi-row simultaneous sowing precision seed sowing device, and belongs to agricultural machinery. An annular seed box, a pipe frame, a motor and four positive and negative bidirectional spiral shafts are respectively arranged on a device frame assembly, four limiting groove plates are fixedly arranged on the bottom wall of the annular seed box, seed conveying single bodies with seed conveying holes are assembled on the limiting groove plates, driven bevel gears are fixedly arranged at the end parts of the positive and negative bidirectional spiral shafts, driving sleeves are sleeved on the positive and negative bidirectional spiral shafts, and the driven bevel gears are fixedly arranged on the end parts of the positive and negative bidirectional spiral shafts. The reversing driving block is mounted on the inner wall surface of a sleeve hole of the driving sleeve, the reversing driving block is inserted into a spiral groove of the forward and reverse bidirectional spiral shaft, the driving sleeve is connected with the seed conveying single body through the connecting frame, four seed guide pipes with V-shaped funnels are fixedly mounted on the device frame assembly and the pipe frame respectively, and the driving bevel gear is fixedly mounted on the motor; according to the device, the seeding operation of multiple rows of seeds can be synchronously completed on the same mechanical seed-metering device, the mounting and matching requirements of a large multi-row mechanical seeding machine are met, and the whole machine is convenient to configure, low in manufacturing and maintenance cost, good in operation quality and high in efficiency.

Description

technical field [0001] The invention belongs to agricultural machinery, and mainly relates to a mechanical precision seed metering device which is driven by bevel gear transmission to realize multi-row synchronous seeding operation of corn. Background technique [0002] The traditional mechanical corn seed meter can only undertake and complete single-row seeding operations. In recent years, with the development of intensive management in China, the land has been concentrated to large planters, and there is an urgent demand for large-scale, high-efficiency and high-tech corn seeding equipment. In order to meet the needs of multi-row large-scale corn seeding equipment, at present, it can only be used to install multiple existing single-row mechanical corn seed metering devices on the multi-row seeding equipment in sequence, that is, according to the number of operation rows. The same number of single-row mechanical corn seed metering devices are not only difficult to configur...

AI Technical Summary

Problems solved by technology

In order to meet the needs of multi-row large-scale corn sowing operation tools, at present, only a plurality of existing single-row mechanical corn seeding devices can be sequentially assembled on multi-row sowing machines, that is, according to the number of operation rows and the number of operation rows. Single-row mechanical corn seed metering devices with the same number, not only the overall configuration and installation of the machine is difficult, the structure is complicated, the weight of the machine is greatly increased, and the manufacturing cost is increased, but also the quality of the sowing operation is not easy to be unified and guaranteed, the failure rate increases, and the maintenance cost increases
