Self-compensation seed supply mechanism and method

Abstract

The invention relates to a self-compensation seed supply mechanism and method. The self-compensation seed supply mechanism structurally comprises a single disc, a seed taking disc, a seed guide pipe, a seed supplementing pipe and a seed box. The device is characterized in that spaced seed feeding holes are formed in the single disc, the single disc is connected with the seed taking disc, the seed guide pipe is tightly attached to the surface of the seed taking disc, and the reseeding pipe penetrates through the seed guide pipe. Negative pressure is generated in the seed taking disc to take seeds at the seed taking position, and the seeds rotate along with the seed taking disc to reach the seed throwing position and enter the seed guide pipe through the seed scraping plate; the seed guide pipe is communicated with the seed feeding hole, and air flow in the seed guide pipe conveys seeds to pass through the seed feeding hole to finish the seed feeding process. If the seeds at the seed feeding position enter the seed guide pipe, the negative pressure borne by the penetrating position of the reseeding pipe and the seed guide pipe is small at the moment that the seed guide pipe is communicated with the seed feeding hole, and the seeds in the reseeding pipe do not enter the seed guide pipe; if no seeds enter the seed guide pipe in the hole of the seed taking disc and the seed feeding position, the negative pressure borne by the penetrating position of the seed supplementing pipe and the seed guide pipe is large at the moment that the seed guide pipe is communicated with the seed feeding hole, and the seeds in the seed supplementing pipe enter the seed guide pipe under the action of the negative pressure to complete self-compensation seed supply.

Description

Technical Field

[0001] This invention relates to a self-compensating seed supply mechanism and method, belonging to the field of precision seeding machinery. Background Technology

[0002] During the sowing process, missed sowing is a common problem, and reseeding is crucial to ensuring germination rate and crop yield. Most existing seeders employ missed sowing detection systems to address this issue. When the system detects a missed sowing hole, a reseeding mechanism is used to replant. While this achieves good detection and reseeding results, the detection system is complex and costly; furthermore, the reseeding mechanism is structurally complex and cumbersome to operate, hindering its widespread adoption. Summary of the Invention

[0003] This invention relates to a self-compensating seed supply mechanism and method, with the aim of realizing the self-compensating seed supply function while simplifying the machine structure and reducing costs.

[0004] This invention relates to a self-compensating seed supply mechanism and method, comprising a single disc, a seed-collecting disc, a seed guide tube, a seed replenishment tube, and a seed box; characterized in that the single disc has spaced seed-feeding holes, the single disc is connected to the seed-collecting disc, the seed guide tube is in close contact with the surface of the seed-collecting disc, and the seed replenishment tube penetrates through the seed guide tube; a negative pressure is generated inside the seed-collecting disc to collect seeds at the seed-collecting position, the seeds rotate with the seed-collecting disc to reach the seed-feeding position, and enter the seed guide tube through a seed scraper; when the seed guide tube is connected to the seed-feeding holes, the airflow inside the seed guide tube transports the seeds through the seed-feeding holes to complete the seed-feeding process; the seed-collecting... There are two seed-collecting states: When the seed-collecting tray is in the seed-collecting state, the seeds enter the seed guide tube through the seed scraper. When the seed guide tube is connected to the seed feeding hole, the negative pressure at the junction of the seed replenishment tube and the seed guide tube is small, and the seeds in the seed replenishment tube do not enter the seed guide tube; When the seed-collecting tray is in the empty state, no seeds enter the seed guide tube at the seed feeding position. When the seed guide tube is connected to the seed feeding hole, the negative pressure at the junction of the seed replenishment tube and the seed guide tube is large, and the seeds in the seed replenishment tube enter the seed guide tube under the action of negative pressure to complete the self-compensating seed supply. This mechanism has a simple structure and low cost.

[0005] Compared with existing technologies, this invention utilizes negative pressure to allow seeds in the replanting tube to self-compensate and enter the seed delivery tube for replanting. It has a simple structure, low cost, and is conducive to the large-scale application and promotion of replanting mechanisms. Attached Figure Description

[0011] The following is in conjunction with the appendix Figure 1-4 The structural principles and implementation schemes of the present invention will be described in detail.

[0012] This invention relates to a self-compensating seed supply mechanism and method, the structure of which includes 1-single disc, 2-seed receiving disc, 3-seed guide tube, 6-replenishment tube and 5-seed box; characterized in that 1-single disc has 4-seed feeding holes at intervals, 1-single disc is connected to 2-seed receiving disc, 3-seed guide tube is close to the surface of 2-seed receiving disc, and 6-replenishment tube passes through 3-seed guide tube.

[0013] The working process of this invention is as follows: During operation, negative pressure is generated inside the 2-seed-taking disc to take seeds at the seed-taking position. The seeds are rotated with the 2-seed-taking disc to reach the seed-feeding position and enter the 3-seed-guiding tube through the seed scraper. When the 3-seed-guiding tube is connected to the 4-seed-feeding hole, the airflow inside the 3-seed-guiding tube transports the seeds through the 4-seed-feeding hole to complete the seed-feeding process. 2-The seed-taking tray has two seed-taking states: When the seed-taking tray is in the seed-taking state, the seeds enter the seed-guiding tube through the seed scraper. When the seed-guiding tube and the seed-infeeding hole are connected, the negative pressure at the junction of the seed-replenishing tube and the seed-guiding tube is small, and the seeds in the seed-replenishing tube do not enter the seed-guiding tube. When the seed-taking tray is in the empty state, no seeds enter the seed-guiding tube at the seed-infeeding position. When the seed-guiding tube and the seed-infeeding hole are connected, the negative pressure at the junction of the seed-replenishing tube and the seed-guiding tube is large, and the seeds in the seed-replenishing tube enter the seed-guiding tube under the action of negative pressure to complete the self-compensating seed supply.
