Double-beveled rocker seeding apparatus

Abstract

The invention relates to a double-beveled rocker seeding apparatus, and belongs to agricultural machinery. The double-beveled rocker seeding apparatus mainly comprises seed box welding (2), a sowing disc combination (4), sprocket welding (6), an alarm device (8), a fixed mandrel (1), a cam (3) and a rubber baffle (9). The sprocket welding rotates to drive the sowing disc welding and a double-beveled seed taking block to make counterclockwise rotation, and a crank arm rotates under the extrusion action of a work surface of the cam to drive the double-beveled seed taking block to rotatably open, so that the double-beveled seed taking block forms a certain opening angle to complete seed filling and clamping actions; and one bevel of the double-beveled seed taking block far away from a turning point screw is a section of concave curved surface, and the other bevel of the double-beveled seed taking block close to the turning point screw is a section of concave inclined surface. The double-beveled rocker seeding apparatus has the advantages of reasonable design, high sowing precision, no wearing parts, high operating speed and stable and reliable performance, and seeds are not easily damaged due to less force on the seeds.

Description

technical field [0001] The invention relates to a seed metering device belonging to agricultural machinery, in particular to a double-slope rocker type seed metering device. Background technique [0002] With the development of science and technology, various high-quality and high-yield corn varieties emerge in an endless stream, and the requirements for the performance and quality of sowing operations are also getting higher and higher. The socket-type and spoon-type seed metering devices mainly used in my country at present are difficult to meet the agronomic requirements of high precision, high efficiency and stable performance. In addition, some seed metering devices imitate foreign models, such as finger clip seed metering devices. The seed metering device has complex structure, high processing technology and material requirements, high production cost, and relatively complicated production and processing of its supporting parts. Therefore, it is of great practical sig...

AI Technical Summary

Problems solved by technology

[0003] The purpose of the present invention is to provide a double-slope rocker-type seed metering device, which can reduce the phenomenon of seed damage, re-seeding, and missing seeding when the seed metering device sows, improve seeding efficiency and reliability, expand the scope of application, and solve the problems of current domestic seed metering devices. The seeding accuracy is low, the operating speed is low, and the seed shape and size are poorly adapted to other shortcomings.
