Problems solved by technology

The first type is a single-row seeder, which has a simple structure, but it is obvious that the sowing efficiency is low because it can only be operated in a single row; the second type is a multi-row seeder, but the sowing distance of this type of machine is mostly fixed It is impossible or inconvenient to adjust to adapt to the planting operations with different requirements in the field, and needs to be improved

Abstract

The invention relates to the technical field of agricultural sowing equipment and particularly relates to an agricultural sowing machine capable of adjusting sowing spacing. A lead screw unit is employed as moving power, a lead screw rotates, and a traveling block moves along an axial direction of the lead screw, so that sliding bases are driven to move through one kind of links and are matched with a telescopic link group, and synchronous equidistant adjusting of the sliding bases is achieved; the sliding bases are connected with seed bins, the seed bins also move in a follow-up manner, and thus, adjustment on sowing spacing is achieved; multiple furrowing components are arranged and are connected with the seed bins in one-to-one correspondence, the seed bins move, and adjusting levers can move along a back and forth direction, so that furrowers can always correspond to a blanking pipe; and a relay bin is also provided with a movable plate for closing, a servomotor III is controlled to drive a cam to act on a pressing plate, the pressing plate also undergoes a spring action, so that the movable plate is driven to move left and right through a push-pull rod to close or open the blanking pipes, and thus, intermittent blanking is achieved.

Description

technical field [0001] The invention relates to the technical field of agricultural seeding equipment, in particular to an agricultural seeder capable of adjusting the sowing distance. Background technique [0002] Agriculture is an industry that produces food and industrial raw materials by cultivating animals and plants. Agriculture belongs to the primary industry, and the science that studies agriculture is agronomy. The objects of agricultural labor are living animals and plants, and the products obtained are the animals and plants themselves. We collectively refer to all departments that use the growth and development laws of animals and plants and other organisms to obtain products through artificial cultivation as agriculture. Agriculture supports the national economy. Basic products for construction and development. Agriculture is a production department in which people use the living functions of animals and plants to transform the substances and energy in nature ...
