Stubble-cleaning, subsoiling, rotary-tilling and ridge-forming combine operating machine

Abstract

The invention provides a stubble-cleaning, subsoiling, rotary-tilling and ridge-forming combine operating machine and belongs to the field of agricultural machinery. The combine operating machine comprises a machine frame, an intermediate transmission case, a stubble cleaning knife shaft, a rotary tilling knife shaft and a subsoiling device, wherein the rotary tilling knife shaft is arranged behind the stubble cleaning knife shaft, the lower margin of rotation circumference of a rotary tilling knife is lower than that of a stubble cleaning knife, the subsoiling device is arranged on the machine frame between the rotary tilling knife shaft and the stubble cleaning knife shaft, the machine frame behind the rotary tilling knife shaft is connected with a ridge-height-adjustable ridge forming device, the ridge forming device comprises a crossbeam and a ridge forming frame, the crossbeam is connected with a ridge height adjusting frame, the ridge height adjusting frame comprises a supporting plate, a connecting plate is arranged on the supporting plate, the supporting plate is hinged with a connecting rack, the connecting rack is hinged with the ridge forming frame, the connecting plate is connected with a moving member which can do rectilinear movement, the moving member is hinged with the ridge forming frame through the connecting rack, a furrowing plate is arranged at the bottom side of the ridge forming frame, the ridge forming frame comprises a ridge forming plate, and the ridge forming plate is arranged behind the furrowing plate. According to the stubble-cleaning, subsoiling, rotary-tilling and ridge-forming combine operating machine, the adjustment on ridge height is achieved so as to meet the requirements of different crops, and the efficiency of farming is increased.

Description

technical field [0001] The invention relates to a compound operation machine, in particular to a stubble removing subsoiling rotary tillage and ridge forming compound operation machine. Background technique [0002] In agricultural production, rotary plowing, loosening and ridging operations are performed on the field land in spring, and agricultural machinery is generally used to complete the operations. In the prior art, the operating machine that realizes ridge removal by rotary tillage loosening is a rotary tillage subsoiling stubble removal ridging machine, which includes a frame, a stubble removal cutter shaft, a rotary tiller cutter shaft, a subsoiling device and a ridging device, and a stubble removal cutter shaft. A number of stubble knives are arranged, a number of rotary tiller knives are arranged on the shaft of the rotary tiller, a subsoiling device is installed on the frame, the subsoiling device includes a mounting seat and a subsoiling shovel, the frame of th...

AI Technical Summary

Problems solved by technology

[0005] When the present invention works, the stubble cutter breaks the soil and removes the stubble, and the subsoiling device performs subsoiling on the basis of the soil layer after the stubble removal, reducing the resistance of subsoiling, and the rotary tiller performs rotary tillage on the basis of subsoiling, reducing the tillage of the rotary tiller Resistance, the ridging device performs ridging on the layer after rotary tillage, when the moving part moves linearly towards the connecting plate, the moving part shortens, the moving part drives the ridging frame to turn upward, and the ridging frame is raised, that is, the ridging plate When raised, the height of the ridging increases; when the moving part moves linearly towards the ridging frame, the moving part becomes longer, the length of the support plate is fixed, the moving part drives the ridging frame to turn downward, and the ridging frame goes down.
