Cross-shaped shaft transmission soil throwing stubble ploughing subsoiling rotary cultivator without blank cultivation

Abstract

The invention discloses a cross-shaped shaft transmission soil throwing stubble ploughing subsoiling rotary cultivator without blank cultivation. Intermediate transmission is adopted in a gear box which is provided with an input gear box, an intermediate transmission case, an output gear box assembly, wherein the input gear box is provided with a power input shaft and an intermediate transmission shaft; the intermediate transmission shaft extends into the intermediate transmission case from the input gear box, and extends into the output gear box from the intermediate transmission case; the intermediate transmission shaft in the output gear box is provided with a lower transmission gear, and is also provided with a power output shaft and a spiral milling cutter transmission shaft; the spiral milling cutter transmission shaft is provided with a spiral milling cutter transmission gear; a spiral milling cutter assembly is arranged on the spiral milling cutter transmission shaft which extends out from the output gear box; a power output shaft is connected with a coupler with a flange plate; and the coupler is connected with a subsoiling cutter shaft assembly with a flange plate. As a separated structure of an upper part, a middle part and a lower part is adopted in the gear box, the gear box is simple in manufacturing, and is strong in generality. The cross-shaped shaft transmission soil throwing stubble ploughing subsoiling rotary cultivator without blank cultivation provided by the invention is convenient in maintenance, low in cost and saving in energy, and has good rotary tillage and stubble ploughing effects.

Description

technical field [0001] The invention relates to a rotary tiller, in particular to a subsoiling rotary tiller for throwing soil and removing stubble with cross-axis transmission without missing tillage. Background technique [0002] According to the current long-term intercropping structure pattern of double-cropping or multi-cropping crops, the land cannot have enough time and opportunity for deep plowing, and the land is easy to harden, making it impossible for crop roots to penetrate deep into the soil to absorb deep water, ground temperature and nutrients. It causes serious consequences such as weak seedlings, sick seedlings, easy to freeze to death in winter, and even lodging and no harvest, which seriously affects grain production and national food security. [0003] With the rapid advancement of my country's mechanization process, the popularization and application of large and super large agricultural machinery, the original matching rotary tiller, stubble remover, ro...

Problems solved by technology

[0002] According to the long-term interplanting structure mode of the current double-cropping or multi-cropping crops, the land cannot have enough time and opportunity for deep plowing, and the land is easy to harden, so that the root system of the crops cannot penetrate deep into the soil to absorb deep water, ground temperature and nutrients.

It has caused serious consequences such as weak seedlings, diseased seedlings, easy to freeze to death in winter, and even lodging and no harvest, seriously affecting grain production and national food security issues

[0003] With the rapid advancement of my country's mechanization process, the popularization and application of large and super large agricultural machinery, the original matching rotary tiller, stubble remover, rotary seeder, ridger, ditcher, subsoiler and other tillage machines The variable speed transmission box is no longer suitable for the supporting use of the current high-horsepower agricultural machinery, and it is easy to cause severe mechanical failures such as broken chains, damaged bearings, gears, and even broken transmission box assemblies, especially for farming machinery with intermediate transmission. The lower end corresponding to the transmission box has a 20cm wide blind area for rotary tillage and stubble removal due to the inability to install the rotary cutter, which has not been able to solve this problem so far.

Directly affect rotary tillage stubble removal and sowing quality, thus affecting grain yield
