Abstract

The invention provides a soil pressing roller with adjustable pressing force and a manufacturing method of the soil pressing roller, belongs to the technical field of agriculture, agricultural engineering, machinery and materials, and particularly relates to the technical field of agricultural machinery. The soil pressing roller comprises a roller body and is characterized in that the roller body is a plastic roller body or a rubber roller body, the roller body is of a hollow cylindrical structure, a water injection hole is formed in the end face of the roller body, and a sealing cover is arranged at the opening of the water injection hole to seal the water injection hole. Traction shafts are arranged on the two end faces of the roller body respectively. When the soil pressing roller is used, water is injected in the roller body, a good pressing effect is achieved, and when the soil pressing roller is not used, water is discharged, and the soil pressing roller is light in weight and convenient to transport. The weight of the soil pressing roller can be regulated by controlling the liquid injection amount, so that the soil pressing roller of different weights is formed so as to adapt to different soil moisture states and different soil pressing force requirements after crops are planted.

Description

technical field [0001] The invention relates to a pressure-adjustable soil pressure roller and a manufacturing method thereof, belonging to the technical fields of agronomy, agricultural engineering, machinery and materials, in particular to the technical field of agricultural machinery. Background technique [0002] The pressure roller is a commonly used agricultural machine. Its main function is to use its own gravity to suppress the soil (especially the soil after sowing), so that the seeds are in close contact with the soil, preventing the soil moisture from being lost too quickly, and protecting the soil moisture. Facilitate seed germination and seedling emergence neatly. Soil suppression is an important link in crop production and one of the important factors affecting crop yield. Most of the existing pressure roll materials are cast iron or low-carbon steel, which has the following problems: first, the cost is high, mainly reflected in the relatively high cost of mat...
