Variable antisticking roller for sowing

Abstract

The invention relates to a variable antisticking roller for sowing and belongs to agricultural machinery. The variable antisticking roller is characterized in that a rolling wheel shaft is mounted at the end part of a roller frame, rolling wheel side plates are mounted at the two ends of the rolling wheel shaft at the inner side of the roller frame, and bearings are fixedly mounted inside the rolling wheel side plates by bearing end covers and are in running fit with the rolling wheel shaft; rubber sleeves are fixedly mounted at outer edges of the rolling wheel side plates; V-shaped rolling wheels and a cylindrical rolling wheel are mounted at the inner side of the rolling wheel shaft in a right-angle-shaped manner; and regulating arms, which form right angles with the V-shaped rolling wheels, are fixedly mounted on the rolling wheel shaft at the outer side of the roller frame, locating screws are mounted at outer ends of the regulating arms through locating holes, and the locating holes are formed in upper and front parts of the rolling wheel shaft on side faces of the roller frame. The variable antisticking roller can separately achieve operating functions of the cylindrical and V-shaped rollers and has the characteristics that the structure is novel, the regulation and operation are simple, easy and convenient, the operating quality is reliable, and the applicable range is wide.

Description

technical field [0001] The invention belongs to agricultural machinery, and mainly relates to a modified anti-stick suppressor for sowing. Background technique [0002] After the seeder fertilizes, sows, and covers the soil, the compactor is used to reduce the soil voids, reduce the evaporation of soil water, and ensure the close contact between the seeds and the soil, so as to facilitate the germination and growth of the seeds. Conventional pressing wheels have main types such as cylindrical, concave-waisted, convex-drum, and conical compound, and each type of pressing wheel has a single adaptation condition. Relevant studies have pointed out that monocotyledonous crops such as corn and wheat have stronger emergence ability compared with dicotyledonous crops such as soybeans and peanuts. Dicotyledonous crops often use V-shaped compaction to achieve soil compaction on both sides of the plant, but the adaptability of each compaction wheel is relatively single. And the rigid...
