A device for realizing the transmission of the inclined cutter head of the rotary tiller

Abstract

The invention provides a device for achievement of transmission of an inclined cutter head of a rotary tiller. The device comprises a side reduction gearbox, a transmission shaft and the inclined cutter head; the transmission shaft is fixedly connected with the output end of the side reduction gearbox; a key groove is formed in the end of the transmission shaft; the inclined cutter head comprises a power pin base, a mounting base, a bearing gland and an offset rotary tilling blade, a power pin is mounted in the key groove, the power pin base is mounted on the power pin, the mounting base is fixed to the outside of the side reduction gearbox, and the power pin base is located in the mounting base; the bearing gland is fixed to the power pin base and matched with the end surface of the mounting base in a sealed mode, the offset rotary tilling blade is mounted on the bearing gland, and the key groove is arranged in an inclined mode relative to the radial section of the transmission shaft, so that an included angle is formed between the inclined cutter head and the radial section of the transmission shaft. By means of the device, a soil layer below a driving gearbox can be removed, the tilling depth of the rotary tiller is increased, oil leakage is prevented, and pollution to the environment is reduced.

Description

technical field [0001] The invention relates to the field of deep rotary tillage, in particular to a device for realizing the transmission of an inclined cutter head of a rotary tiller. Background technique [0002] A rotary tiller is a tillage machine that is matched with a tractor to complete plowing and harrowing operations. It has been widely used because of its strong soil breaking ability and flat surface after plowing. At the same time, it can chop up the root stubble buried below the surface, which is convenient for the seeder to operate and provides a good seed bed for later sowing. [0003] The patent application number is 201610196596.6, a deep rotary tiller with intermediate transmission. Although it solves the problem of removing the soil layer under the intermediate transmission gearbox and increases the tillage depth of the rotary tiller, because the power transmission cylindrical pin is in line contact in the keyway, it wears quickly. , easy to generate heat...

Problems solved by technology

[0003] The patent application number is 201610196596.6, an intermediate drive deep rotary tiller. Although it solves the problem of removing the soil layer under the intermediate drive gearbox and increases the tillage depth of the rotary tiller, it wears quickly because the power transmission cylindrical pin is in line contact in the keyway. , easy to generate heat, and the sealing of the intermediate transmission box is not well resolved, and the service life is short
