Cycle-adjustable seeding device

Abstract

The invention discloses a cycle-adjustable seeding device which comprises an operation mounting plate. Vertically downward triangular support mounting plates are arranged on the lower side of the leftend of the operation mounting plate in a sagittal symmetry manner, uniform seeding drums are arranged between the triangular support mounting plates on front and rear sides in a coaxially matched manner through support bearing sleeves arranged at the lower ends of the triangular support mounting plates in a symmetrically penetrating manner, two groups of flow-limiting blanking cylinders are coaxially arranged inside the uniform seeding drums, a plurality of flow-limiting blanking holes are formed in the outer sides of the flow-limiting blanking cylinders on the inner side and the outer side in a staggered and uniformly penetrating manner, a plurality of uniform blanking holes are formed in the outer sides of the uniform seeding drums in a uniformly penetrating manner and matched with theflow-limiting blanking cylinders, and feeding bearing barrels are arranged at the front ends and the rear ends of the uniform seeding drums in a penetrating manner and matched with the support bearingsleeves. The cycle-adjustable seeding device has the advantages of compact structural design, stable transmission process, adaptive cyclic variable transmission, accurate and uniform seeding processand the like.

Description

technical field [0001] The invention relates to an agricultural machine, in particular to a cycle-adjustable sowing device. Background technique [0002] Seeder is a planting machine that uses crop seeds as the sowing object. The seeder used for a certain type or a certain crop is often named by the name of the crop type, such as grain drill, corn hole seeder, cotton seeder, pasture spreader, etc. However, due to the continuous sowing structure, the fixed transmission structure, and the fixed transmission cycle structure of the traditional sowing device, various problems appear in actual use. [0003] In order to solve the above problems, the present invention is proposed, which overcomes the currently used sowing device. Due to the continuous sowing structure, the displacement of the sowing device is accelerated with the speed of sowing, causing the sowing process to be unstable and the high-speed moving sowing is uneven. and other problems, solve the currently used sowing...

Problems solved by technology

However, due to the continuous sowing structure, the fixed transmission structure, and the fixed transmission cycle structure of the traditional sowing device, various problems arise in actual use.

[0003] In order to solve the above problems, the present invention is proposed, which overcomes the currently used sowing device. Due to the continuous sowing structure, the displacement of the sowing device is accelerated with the speed of sowing, causing the sowing process to be unstable and the high-speed moving sowing is uneven. and other problems, solve the currently used sowing device, due to the fixed transmission structure, the transmission process is poor, and the uniform sowing process is hindered, etc., and the currently used sowing device is improved. Single, can not be adjusted according to different sowing requirements, so that the present invention has the advantages of compact structure design, stable transmission process, adaptive periodic variable transmission, accurate and uniform sowing process, etc.
