Abstract

The invention provides a dynamic and static shovel type high-speed precision seed discharging device suitable for subsphaeroidal seeds. The device is composed of a fixed shell, a cam seat, a transmission ring, a shovel type positive seed picking device, a transmission disc, a seed discharging shaft, a rod sleeve, a cam roller, a sleeve, a push rod bearing, an end cover, a seed protection ring anda seed inlet tube, wherein an opening of the seed inlet tube is upward, the tube wall of the lower portion is connected with the lower portion of the shell, the transmission disc cooperates with the seed discharging shaft and the transmission ring, the rod sleeve and the transmission ring perform clamping, the lower portion of the rod sleeve is connected with the shovel type positive seed pickingdevice, the seed protection ring is connected with a bottom plate of the seed picking device, a cam disc is connected with the fixed shell, the profile curve of a cam is in contact with the cam roller, the cam roller is connected with a push rod, a pressure spring is arranged between the head of the push rod and the sleeve, the push rod cooperates with the sleeve through a sliding bearing, and thetip of the push rod penetrates through a through hole of a top plate of the seed picking device. According to the device, through a method of partitioning to-be-removed seeds and to-be-discharged seeds and restraining the to-be-discharged seeds through the tip of the push rod, high-speed precision seeding is achieved.

Description

technical field [0001] The invention relates to a seed metering device suitable for nearly spherical granular materials, in particular to a dynamic and static bucket shovel type high-speed precision seed metering device, which belongs to the technical field of agricultural machinery. [0002] technical background [0003] The precision seed meter is the core component of the seeder, mainly including mechanical and pneumatic precision seed meter. The working performance of the seed meter directly affects the accuracy, efficiency, and germination rate of seeds. The mechanical precision metering device is popular among farmers because of its simple and compact structure, convenient operation and maintenance, and low cost. Due to the limitations of its own structural design, the existing mechanical precision seed metering device has a linear drop in seed metering accuracy under high-speed and field vibration conditions, which cannot meet the technical requirements of precision s...
