Description

Technical Field

[0001] This utility model relates to the field of soil entry wheel technology, specifically a soil entry wheel gap adjustment device. Background Technology

[0002] The soil entry wheel is a key working component in agricultural machinery, commonly found in seeders, covering machines, and other similar equipment. Its main function is to directly contact the soil and complete specific soil entry operations. In seeding operations, the soil entry wheel can precisely control the seeding depth, ensuring that the seeds are in a suitable soil environment, which is conducive to germination and growth. In covering operations, it can evenly cover the seeds or fertilizers with soil, playing a role in heat preservation, moisture retention, and preventing nutrient loss. In practical agricultural production, the existing soil-penetrating wheels have fixed gaps that cannot be adjusted. When faced with soils of different textures and densities, the soil-penetrating wheels cannot adapt flexibly. In relatively loose soils, the gaps may be too small to penetrate the soil smoothly, causing obstruction of operations and affecting the normal progress of sowing or covering. In compacted soils, the gaps may be too large to achieve the ideal penetration depth, resulting in inconsistent sowing depths and uneven soil covering, which in turn affects the germination rate of seeds and the growth quality of crops.

[0003] Therefore, a gap adjustment device for the soil entry wheel is proposed. Utility Model Content

The upper end of the adjusting rod 37 passes through the adjacent soil entry frame 33 and is fixedly connected to the adjacent soil entry frame 33.

[0022] Furthermore, in this embodiment, the top surface of the upper connecting bracket 31 is fixedly connected to the bottom surface of the mounting plate 1, and the upper and lower connecting brackets 31 are fixedly connected to each other on the side by the connecting rod 32. One end of the soil entry frame 33 is hinged to the adjacent connecting rod 32. Multiple soil entry frames 33 are evenly arranged to provide a structural basis for gap adjustment. The base 34 is located at the lower end of the lower connecting bracket 31 and is connected to the lower end bearing of the connecting bracket 31.
