Description
Technical Field
The invention relates to the technical field of agricultural machinery, in particular to an inner deflection blade type ditching cutter head and a driving device thereof.
Background
The ditching machines which are most widely used at present are divided into a middle driving type and a single-side driving type according to driving positions, wherein the single-side driving type can be divided into a gantry type single-side driving type and a cantilever type single-side driving type. Generally, the intermediate driving type is generally applied to small-sized self-propelled ditchers, such as small-sized fruit and forest ditchers, vineyard ditching fertilizer applicators, tea-garden ditching fertilizer applicators and the like; the single-side driving type ditcher is generally applied to ditchers hooked by large tractors, such as rape shallow ploughing ditchers, chain type pipeline ditchers and the like. The ditching machine is mainly applied to forests, orchards and vegetable gardens, and is used for cable pipeline construction in a small amount. Besides cable pipeline construction ditching, the agricultural requirements of ditching in forest gardens, orchards and vegetable gardens generally have the ditch width of 40CM and the ditch depth of within 50 CM. The small ditches are driven by large tractors with the weight of 2-3 tons, the power of about 50KW and the width of about 1.4M, obviously unreasonable, and the adoption of small self-propelled ditchers is a necessary trend for future development.
Although the small-sized self-propelled ditcher is compact and small in structure, and can ditch for multiple times on the basis of one-time ditching, the ditching depth is improved, and after multiple times of ditching, the maximum depth can reach more than 50CM, and is even larger than that of a ditcher driven by a common large tractor. However, the small-sized self-propelled ditcher generally adopts a middle driving mode, such as a single-side driving mode, which causes the structure to be complicated, the weight of the ditching mechanism to be increased, the operation to be difficult, and a deep ditch cannot be opened; the middle driving type small-sized self-propelled ditcher causes the ditching cutter heads to be symmetrically arranged at two ends of the transmission because the transmission occupies the middle part of the cutter heads, but when the ditching is carried out by rotary tillage, the part occupied by the transmission in the middle of the ditching cutter heads can not ditch and cut soil, and the ditcher can only ditch into two ditches similar to W, thereby not meeting the agricultural requirements. In order to solve the problems, the small-sized self-propelled ditching machine is provided with a small-sized ditching plow at the lower end of a speed changer, and actually forms the small-sized self-propelled rotary tillage ploughing ditching machine. In northern areas of China, dry sandy soil is generally taken as a main material, the ditching plow of the ditching machine with the structure plows part of the dry sandy soil occupied by the transmission and then pushes the part of the dry sandy soil to the ditching cutter head, and the rotary ditching cutter head breaks and throws the part of the dry sandy soil out, so that ditching operation is realized, and the agricultural requirement of local ditching can be met. However, most of southern China mainly uses moist cohesive soil, the ditching plow of the ditching machine with the structure can only push a small amount of soil blocks shielded by the transmission to the ditching cutter head, a large amount of soil blocks are accumulated near the transmission, the ditching cutter head is blocked by the soil blocks, and the ditching cutter head cannot continuously run. In actual practice, it is difficult to open a trench of about 1M in wet and sticky soil.
