Maneuvering type front and back driving convention planting precision seeder

Abstract

The invention relates to a maneuvering type front and back driving convention planting precision seeder, which comprises a rack, wherein the rear end on the top of the rack is provided with a handle component, the front end of the top of the rack is provided with an engine, and the middle is provided with a campana box; the rear end of the bottom of the rack is provided with rear driving press wheels, and the front end of the bottom of the rack is provided with front driving wheels; the front driving wheels and the engine are in transmission connection through a chain; the rear driving press wheels are connected through chain transmission; the rear driving press wheels or the front driving wheels and a spindle connected with the rack are installed on the rack through a unilateral bearing; each rear driving press wheel comprises a columnar wheel body and ground gripping gears arranged on two ends of the wheel body, wherein the root circle diameter of each ground gripping gear is greater than or equal to the diameter of a wheel body; the front driving wheels and the rear driving press wheels have the same structure. In a sowing process, the seeder does not skid, sowing quality is good, and a yield is high. Meanwhile, the driven chain wheel on the end part of the driving shaft of the campana box is changed to control sowing density, an applicable sowing range is wider, and cultivation is effectively improved.

Description

technical field [0001] The invention relates to the field of agricultural machinery, in particular to a seeder for sowing. Background technique [0002] As a kind of agricultural production equipment, the seeder has a history of thousands of years. The seeder plays an important role in agricultural production. With the development of modern agriculture, there are more and more types of seeder, and more and more The improvement of the seeder has greatly reduced the labor force, and has changed the agricultural production method very well. However, most of the seeders currently on the market are complex in structure, high in cost, large in power, and complicated in operation, which put forward higher requirements on the power strength of agricultural machinery and users, and cannot control the density of sowing. Especially the planters designed for small-area sowing are mostly in the form of hand-held, but they are prone to slipping during the sowing process on the ridge, res...

Problems solved by technology

However, most of the seeders currently on the market are complex in structure, high in cost, large in power, and complicated in operation, which put forward higher requirements on the power strength of agricultural machinery and users, and cannot control the density of sowing.

Especially the planters designed for small-area sowing mostly adopt the form of hand-held, but they are prone to slipping during the sowing process on the ridge, resulting in low sowing quality and survival rate. The number of migrant workers is increasing, and the labor force is gradually decreasing. In order to ensure the normal progress of agricultural production, there is an urgent need to provide relevant agricultural machinery to improve farming efficiency.
