Seed pre-cutting type sugarcane seed metering device

Abstract

The invention provides a seed pre-cutting type sugarcane seed metering device. The seed pre-cutting type sugarcane seed metering device comprises a seed filling box, a primary seed metering roller, a seed metering box and a secondary seed metering roller. The specific structure and the connection relation of the parts are that an outlet of the seed filling box is connected with a seed filling baffle plate, the primary seed metering roller is uniformly and fixedly connected with primary shifting plates, an outlet of the seed metering box is connected with a seed metering baffle plate through a spring, a flow-dividing roller shaft is connected with a flow-dividing roller, and the secondary seed metering roller is uniformly and fixedly connected with secondary shifting plates. By the adoption of the seed pre-cutting type sugarcane seed metering device, the seed leakage rate in the sugarcane seed metering process can be effectively reduced, the sugarcane seed metering clamping phenomenon is reduced, the uniformity in the seed metering process is improved, machine vibration is reduced, and precise seed metering is achieved.

Description

technical field [0001] The invention relates to the field of agricultural machinery, in particular to a pre-cut seed metering device for sugarcane. Background technique [0002] The typical structure of the seed meter is mainly divided into real-time cutting type and pre-cutting type. At present, the real-time cutting planter is the most widely used model in agriculture. As the area with the largest sugarcane planting area in the country, the roll-cutting seed metering device is mostly used in the mechanized planting of sugarcane in Guangxi. This structure is used The seed metering device needs to be manually fed, which is labor-intensive, requires a lot of personnel, and the sugarcane is often bent, so it is not easy to feed the mechanism. The speed of manual feeding is different, resulting in poor seeding uniformity; when cutting seeds in real time, the seedlings are easy to damage buds and break. Buds will affect the germination rate; incomplete disinfection will affect ...
