Rice and wheat annual area non-smooth pressing roller

Abstract

The invention discloses a rice and wheat annual area non-smooth pressing roller which comprises a plurality of roller bodies which are sequentially in butt joint along the axis. A roller shaft is arranged in the centers of the roller bodies, and the roller bodies located at the two ends are each provided with an axial positioning device fixed to the roller shaft; and elastic-plastic convex hulls are evenly distributed on the matching face between any two adjacent roller bodies, the elastic-plastic convex hulls and the two corresponding roller bodies are fixedly installed in a matched manner through clamping devices, and the clamping devices also act on circumferential positioning devices for positioning all the roller bodies. The surface, making contact with soil, of the rice and wheat annual area non-smooth pressing roller is a non-smooth surface, the impact effect on the soil is increased compared with a traditional pressing roller in the operation process, and the impact compactioneffect is achieved in the process; and the convex hulls are made of elastic-plastic materials, so that when the convex hulls interact with the soil, the convex hulls deform and make flat-bottom contact with the soil, local impact force on the soil is reduced, meanwhile, after the convex hulls leave the soil, the convex hulls rebound, the adhered soil can be bounced off, and the purpose of reducingsoil adhesion is achieved.

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...
