Mechanical clutch transmission device for combined seed and fertilizer drill

Abstract

The invention discloses a mechanical clutch device for a combined seed and fertilizer mill. The mechanical clutch device comprises a clutch flange. One end of the clutch flange is fixedly provided with a main drive shaft through a semi-clutch A. The end, opposite to the above end, of the clutch flange is fixedly provided with a spline shaft through a semi-clutch B. The semi-clutch A and the semi-clutch B which are provided with teeth on the opposite end faces form a jaw clutch. The spline shaft is fixed to the clutch flange through cascading connection of a bearing and a bearing seat. The free end of the spline shaft is fixedly provided with a chain wheel through a clamp spring. A spline shaft body is axially provided with a compression spring. The semi-clutch B is connected with the semi-clutch A under the action of the compression spring. A shifting fork ring is circumferentially arranged on the semi-clutch B. A shifting fork bar is correspondingly arranged in the shifting fork ring and fixed into the clutch flange through a guide cover. The free end of the shifting fork bar is connected with a control end through a wiring assembly. The mechanical clutch device is stable, reliable and easy to operate, avoids seedling missing and excessive seeding, reduces waste and guarantees that production and income of crops are increased.

Description

technical field [0001] The invention relates to the technical field of agricultural machinery equipment, in particular to a mechanical clutch transmission device for a fertilizing and seeding machine. Background technique [0002] In order to improve the quality of sowing and realize the application purpose of precise sowing of crops, agricultural machinery has gradually been valued by the country, and the mechanical properties of its sowing and fertilizing agricultural machinery are also in urgent need of improvement. For example, the sowing and fertilization of crops such as wheat, corn, sorghum, soybeans, and peanuts is very important. The mechanical transmission device of the existing seeder fertilizer, its power comes from the ground wheel, and the ground wheel drives the sowing and fertilization wheels by itself. Affected by the quality of the work plot, the work is unstable. When encountering large clods and uneven plots, The rotation of the ground wheel is not flexi...

Problems solved by technology

The mechanical transmission device of the existing seeder fertilizer, its power comes from the ground wheel, and the ground wheel drives the sowing and fertilization wheels by itself. Affected by the quality of the work plot, the work is unstable. When encountering large clods and uneven plots, The rotation of the ground wheel is not flexible, sometimes it is overhead, and the ground wheel stops rotating, resulting in missed seeding, easy to lack seedlings, affecting the quality of sowing, and directly affecting the yield of crops
