Binary-power driving transmission mechanism of double inter-tilling and weeding operation machine

Abstract

The invention discloses a binary-power driving transmission mechanism of a double inter-tilling and weeding operation machine, and belongs to the field of agricultural machines. A transmitting box assembly is fixedly installed on a machine frame assembly, first power-outward-transmitting transmitting chain wheels are fixedly installed on a power output shaft of the transmitting box assembly, second power-outward-transmitting transmitting chain wheels and third power-outward-transmitting transmitting chain wheels are fixedly installed on a front driving shaft, and fourth power-outward-transmitting transmitting chain wheels are fixedly arranged on center shafts of front-tooth-disc combination weeding rollers; first power-outward-transmitting driving chains are installed on the first power-outward-transmitting transmitting chain wheels and the second power-outward-transmitting transmitting chain wheels in a sleeving mode, and second power-outward-transmitting driving chains are installed on the third power-outward-transmitting transmitting chain wheels and the fourth power-outward-transmitting transmitting chain wheels in a sleeving mode; first ground-wheel power-transmitting chain wheels and a ground wheel are fixedly installed on a back driving shaft, second ground-wheel power-transmitting chain wheels are fixedly installed on center shafts of back-tooth-disc combination weeding rollers, and ground-wheel driving transmission chains are installed on the first ground-wheel power-transmitting chain wheels and the second ground-wheel power-transmitting chain wheels in a sleeving mode. By means of the binary-power driving transmission mechanism, the front-tooth-disc combination weeding rollers and the back-tooth-disc combination weeding rollers are driven by different driving power sources, the structure is novel and reasonable, adaptive capacity is high, working quality is good, and efficiency is high.

Description

technical field [0001] The invention belongs to agricultural machinery, and mainly relates to a mechanical cultivating and weeding operation machine. Background technique [0002] In order to improve the quality of intertillage and weeding operations and the efficiency of machine tools, a compound intertillage and weeding machine with a toothed plate combined weeding roller at the front and rear above the same ridge was initially successfully developed. At present, the power source of the rotary movement of all the tooth discs combined with the weeding rollers of the compound cultivator weeder of this type is either driven by a single implement ground wheel, or driven by the output power of a single traction tractor power output shaft, and the implement operation is poor in adapting to land conditions. Especially when the moisture content of the soil is high and the soil viscosity is high, the ground wheel slip rate of the implement increases, and the rotating speed of the c...

AI Technical Summary

Problems solved by technology

At present, the power source of the rotary motion of all the tooth discs combined with the weeding rollers in the compound cultivator weeding machine of this type is either driven by a single implement ground wheel, or driven by the output power of a single traction tractor power output shaft, and the implement operation is poor in adapting to land conditions. Especially when the soil moisture content is high and the soil viscosity is high, the slippage rate of the ground wheel of the implement increases, and the speed of the weeding roller combined with the front and rear tooth discs decreases, which seriously affects the effect of weeding and intertillage operations

The model is driven solely by the output power of the tractor power output shaft, the speed of the combined weeding roller of the front and rear toothed discs is not easy to control, the performance and applicability of the machine tool are reduced, and the operator's operating level is high.
