AI Technical Summary
Technical Problem
The fixed connection between the compaction roller and the frame of traditional rotary tillers makes it difficult to dynamically adjust under different soil conditions, resulting in excessive soil compaction or insufficient pressure, which affects the quality of sowing.
Method used
A terrain-adaptive compaction depth control mechanism was designed. The compaction roller depth is adjusted by hydraulic rods and spring supports. Combined with rotary tillage, soil covering and sowing components, it can adapt to different soil conditions and ensure consistent sowing depth and soil porosity.
Benefits of technology
It effectively reduces the formation of soil compaction, improves sowing quality, reduces fertilizer loss, and enhances rotary tillage efficiency and sowing consistency.

Abstract
The utility model belongs to the agricultural machinery technical field, specifically is a kind of with local shape and is pressed depth control mechanism, including frame;The frame top is rigidly connected with hopper;The baffle is rigidly connected in the middle of hopper;Two fixed plates are rigidly connected in the frame side wall;Two The fixed plate is set up oppositely;Two support plates are rigidly connected in the middle of frame;Two hydraulic rods are rigidly connected in the frame side wall;Driving plate is rotatably connected in the middle of fixed plate;Spring support rod is rigidly connected in the middle of driving plate;Driving plate is rotatably connected in the middle of connecting rod;Connecting rod end is slidably and rotatably connected in the middle of spring support rod;Through the above structure, the depth of the rolling press can be adjusted according to the condition of soil, the soil can be effectively reduced, the soil is excessively compacted due to high water content and high viscosity, the soil porosity is reduced to form a hardening layer, and the seed germination and root growth are hindered.
