Seeding device with high seeding uniformity

Abstract

The invention discloses a seeding device with high seeding uniformity, and relates to the technical field of seeding devices. The seeding device includes a machine frame, a sliding plate is horizontally arranged inside the machine frame, a seeding tube is arranged under the sliding plate, and a cam and a storage bin are arranged above the sliding plate. A seeding guide block capable of sliding horizontally is arranged under the seeding tube, a first spring sleeves the seeding guide block, a fixed plate is arranged above the seeding guide block, and baffle plates and second sliding grooves areformed in the two sides of the connecting tube on the fixed plate. Return springs are arranged in the second sliding grooves, a movable rod is arranged under the seeding guide block, a conical push block is fixedly arranged at the upper end of the movable rod, and the two ends of the movable rod are slidably embedded in first sliding grooves through first connecting rods. The depth of seeding canbe controlled, the seeding amount of a seeding point can be controlled, the seeding tube directly penetrates into the soil, the step of soil covering is avoided, and a material outlet is not be blocked.

Description

technical field [0001] The invention belongs to the technical field of sowing devices, and in particular relates to a sowing device with high sowing uniformity. Background technique [0002] With the rapid development of agricultural mechanization, planters are becoming more and more popular. The sowing depth and sowing uniformity of the seeds sown in the prior art are difficult to be guaranteed, and it takes a lot of time and effort, which affects the growth of the seeds. [0003] The publication number is CN107347313A Chinese invention patent application, which discloses a uniform agricultural seeder, including a base, a lifting plate, a left pillar, a fixed plate, a right pillar and a seeding tube; the upper right side of the lifting plate is provided with a crankshaft, Two cranks are arranged symmetrically on the top, and a rotating sleeve is installed on the crank, and two connecting rods are also symmetrically installed on the lifting plate, and the connecting rods are...

Problems solved by technology

In this application, the discharge port is set above the drill bit, and no protective device is added. The discharge port is easily blocked by soil, which will lead to the failure of discharge, and even if the discharge port is partially blocked, it will also cause the number of seeds at some sowing points Much smaller than other sowing points, affecting later yield
