Efficient disc type ditcher

Abstract

The invention discloses an efficient disc type ditcher, and relates to the technical field of agricultural machines. The efficient disc type ditcher comprises a rack, a driving assembly is fixedly connected to the middle of the rack, driving shafts are coaxially and fixedly connected to the output ends of the two ends of the driving assembly, and the two ends of the two driving shafts are rotationally connected to the rack; and ditching cutter discs are fixedly and coaxially connected to the middles of the driving shafts, and a plurality of ditching curved knives are connected to the faces, away from each other, of the two ditching curved knives. Compared with a traditional disc-type ditcher which needs an ultra-low-speed large-torque driving assembly for driving, the disc type ditcher hasthe advantages that when hard soil and stones are encountered during excavating, instantaneous acting force between the ditching curved knives and the ditching cutter discs can be effectively reduced, tree roots or other obstacles hooking the ditching curved knives can be cut and broken, so that peak torque between the ditching curved knives and the ditching cutter discs is reduced, a driving assembly with higher rotating speed can be selected, the rotating speed of the ditching cutter discs is increased, and the excavation efficiency of the disc type ditcher is improved.

Description

technical field [0001] The invention relates to the technical field of agricultural machinery, in particular to a high-efficiency disc type ditching machine. Background technique [0002] Ditching machine is a machine for digging trenches. It is often used in agriculture or forestry to dig ditches for planting crops or trees. It is also commonly used for digging ditches required for laying underground pipelines, cables and other projects. Existing trenchers are generally divided into excavator type, chain type, disc type and plow type. Among them, the disc type trencher is suitable for the excavation of small-scale projects such as asphalt roadsides, village ditches, cables or fields. The disc trencher mainly performs ditching by the rotation of the ditching cutter head with ditching machetes in the circumferential direction. [0003] The existing ditching machete and the ditching cutter head are fixedly connected directly by bolts, and the ditching machete protrudes from t...

AI Technical Summary

Problems solved by technology

[0004] The invention proposes a high-efficiency disc-type ditching machine. The purpose is to solve the problem that the ditching machete and the ditching cutter head are directly fixedly connected by bolts in the traditional technology, which is easy to cause the ditching machete to collide with the ground on bumpy roads. The problem that the ditching machete and ditching cutter head are easily damaged when rotating excavation encounters resistance
