Problems solved by technology

The traditional machete cutter head has poor cutting performance, weak ability to open deep grooves, and high power consumption; the chain-type cutter head is small in size, easy to adjust the depth, and has better ditching performance, but it has many links and lower reliability. High requirements on chain material and processing precision, high cost; helical milling cutter head has simple structure and good groove formability, but the cutter body is longer, and the rigidity of the ditching cutter becomes worse when digging deep grooves, and it is affected by soil quality. Clay soil will cause unearthed phenomenon

Embodiment Construction

[0021] figure 1 Shown is the trencher cutter head of the present invention, including spokes 2, hub 1, annular knife holder 3 and at least one set of trenching knife sets, said trenching knife set including several trenching knives 4. The ditching knife 4 is fixed on the annular knife holder 3, and the annular knife holder 3 and the hub 1 are connected by the spokes 2, and the ditching knife 4 is in the shape of a hook. The ditching knives 4 are evenly arranged on the circumference of the annular knife seat 3 and arranged in a staggered order in the axial direction of the annular knife seat 3 .

[0022] Such as figure 2 As shown, in order to facilitate trenching, the width of the annular knife seat 3 needs to be smaller than the width of the ditch, so the ditching knives 4 on the left and right sides are respectively inclined to the left and right γ=5°~8°, so that the knife head protrudes from the side of the knife seat Edge distance 5 ~ 8mm. Ditching knife 4 is made up of...

Abstract

The invention discloses a cutter head of a furrowing machine, which comprises an annular cutter holder and at least one furrowing cutter set, wherein the furrowing cutter set comprises a plurality of furrowing cutters which are hook-shaped and uniformly arranged around the annular tool holder in an alternating way in the axial direction of the annual cutter holder. According to the technical proposal, the shape of the furrowing cutters is like that of the paws of ants and pangolins, so that the furrowing cutters meet the minimum shallow-layer excavation resistance each time and are suitable to be used in a forest field or hard soil; and the alternating arrangement of the furrowing cutter set allows for layered and alternating cutting of the furrow earth and greatly reduces the power for single cutting, thereby improving the overall furrowing capacity of the furrowing cutter set and making the cutter head of the furrowing machine simple in structure and reliable in work.

Description

technical field [0001] The invention relates to a ditching machine cutter head, which belongs to the technical field of agricultural machinery. Background technique [0002] The cutter heads of existing trenchers are of various types, such as disc type, chain type, and helical milling cutter type. The traditional machete cutter head has poor cutting performance, weak ability to open deep grooves, and high power consumption; the chain-type cutter head is small in size, easy to adjust the depth, and has better ditching performance, but it has many links and lower reliability. High requirements on chain material and processing precision, high cost; helical milling cutter head has simple structure and good groove formability, but the cutter body is longer, and the rigidity of the ditching cutter becomes worse when digging deep grooves, and it is affected by soil quality. Clay soil can cause unearthed phenomena. Contents of the invention [0003] The technical problem to be s...
