Non-smooth pressure roller for rice and wheat anniversary area

Abstract

The invention discloses a non-smooth pressure roller in the rice and wheat anniversary area, which comprises a plurality of roller bodies which are sequentially butted along the axis, a roller shaft is arranged at the center of the roller body, and the roller bodies at both ends are respectively provided with roller shafts fixed on the roller shaft. Axial positioning device; elastic-plastic convex hulls are evenly arranged on the mating surface between any adjacent two roller bodies, and the elastic-plastic convex hull and the corresponding two roller bodies are fixed and installed through a snap-in device, and the snap-in device It is also used as a circumferential positioning device for positioning each roller body; the surface of this device used to contact the soil is a non-smooth surface, and it has more impact on the soil than the traditional pressure roller during operation. This process has the effect of impact compaction ; The convex hull is an elastic-plastic material, so that when the convex hull interacts with the soil, the convex hull deforms and contacts the soil with a flat bottom, reducing the local impact on the soil. At the same time, after the convex hull leaves the soil, the convex hull rebound can make the adhesion The soil is bounced off to achieve the purpose of reducing soil adhesion.

Description

technical field [0001] The invention relates to the technical field of agricultural machinery, in particular to a non-smooth pressing roller in the rice-wheat anniversary region. Background technique [0002] Since the 1960s, my country's rice-wheat direct seeding machine has developed rapidly, mainly used in rice-wheat rotation areas, including Jiangsu, Anhui, Henan, northern Hubei, northern Sichuan and southern Shaanxi, across the east and middle of my country. and west. The rice and wheat direct seeding machine consists of a suspension frame, a rotary tillage mechanism, a seeding and fertilizing mechanism, transmission parts, and a suppression device. The power is transmitted to the central gearbox through the tractor power output shaft, and then the power is transmitted to the rotary tiller by the side transmission box. The shaft completes the rotary tillage operation, and the seeding and fertilizer discharge power comes from the pressing wheel, which can complete the ro...
