A sowing device with high sowing uniformity

Abstract

The invention discloses a sowing device with high sowing uniformity, relating to the technical field of sowing devices, comprising a frame, a sliding plate is arranged horizontally inside the frame, a seeding pipe is arranged under the sliding plate, and a cam and a storage tank are arranged above the sliding plate. The silo, below the sowing pipe, is provided with a horizontally sliding seed guide block, the first spring is sleeved on the seed guide block, a fixed plate is provided above the seed guide block, and stoppers and second springs are provided on both sides of the connecting pipe on the fixed plate. Two chutes, a return spring is arranged in the second chute, a movable rod is arranged below the seed guide block, a tapered push block is fixedly arranged on the upper end of the movable rod, and the two ends of the movable rod slide and are embedded in the second connecting rod through the first connecting rod. In a chute; the present invention can control the depth of sowing, and the sowing rate of the sowing point can be controlled, the sowing pipe is directly penetrated into the soil, eliminating the step of covering the soil, and the discharge port will 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
