Rice seed quantitative discharging mechanism

Abstract

The invention relates to a rice seed quantitative discharging mechanism. The mechanism comprises a seed containing wheel, an end face bearing, an inner wheel and a shell, a plurality of teeth with seeds are distributed along the circumference of the seed containing wheel, the inner wheel is contained in the seed containing wheel, and the end face bearing is installed on the side, making contact with the inner side of the seed containing wheel, of the end face of the inner wheel. The shell is arranged on the outer side of the seed containing wheel and the inner wall, and seed containing groovesare formed in the teeth with the seeds. A vacuum channel and a pressure channel communicated with the seed containing grooves are formed in the inner wheel, the vacuum channel is connected with a vacuumizing device, the pressure channel is connected with a pressure device, and discharge openings communicated with the seed containing grooves in the teeth with the seeds are formed in the bottom ofthe shell. The seed containing wheel is driven by a driving device, and the driving device, the vacuumizing device and the pressure device are electrically connected with a control device. The rice seeds are sucked into the mechanism from a feed inlet, through rotation of the seed containing wheel, air blowing and discharging are conducted at the discharging openings, abundant seeds are collectedwith a storage hopper, and the requirement of rice seed films for precise quantification is met.

Description

technical field [0001] The invention relates to a quantitative seed discharging mechanism, in particular to a rice seed quantitative discharging mechanism, which belongs to the innovative technology of the rice seed quantitative discharging mechanism. Background technique [0002] The main disadvantage of the existing rice seed quantitative discharging mechanism is that the seed quantitative is not accurate, and generally there will be many seeds in one hole, which not only wastes rice seeds, but also is not conducive to the planting quality of rice. At the same time, the existing rice direct seeding technology is implemented in the field, and the agricultural rice planting machinery developed is mainly oriented to field operations. Rice seed film is a new concept, and the agricultural machinery for producing rice seed film can be said to be blank. For the industrialized seed film production, due to the different operating environment and mechanization degree, it is necessa...
