Embodiment Construction

[0025] See attached figure 1 , 2 , in the embodiment of the present invention, the shift fork combination 5 includes a shift fork handle body 5-1, a shift fork handle 5-2, a shift fork 5-3, a steel ball 5-4, a shift fork spring 5- 5. The transmission gear combination 3 includes the transmission gear I3-1, the transmission gear II3-2, and the transmission gear III3-3; the transition gear spline shaft is equipped with the I gear transition gear 7, the II gear transition gear 18, and the III gear transition gear 6 , spacer I8, spacer III19; the output gear 12 on the output shaft is axially positioned by the shaft shoulder and the spacer II; adjust the axial position of the shift fork on the shift fork shaft by turning the handle of the shift fork, and adjust here During the process, the relative position of the steel ball is changed through the expansion and contraction of the shift fork spring, so that the shift fork can slide freely. When moving 32.4mm to the left, the transm...

Abstract

The invention relates to a three-speed variable transmission device for a threshing cylinder of a semi-feeding rice and wheat combine harvester capable of adjusting the threshing speed, which is transmitted through an input shaft, a transition gear spline shaft and an output shaft, wherein power is transmitted to the input shaft through a coupler, then a change gear is regulated by using a gear shift fork to realize three-gear speed change, and then the power is transferred at equal speed through I-level gears on the transition gear spline shaft and the output shaft, output by the output shaft and transmitted to the threshing cylinder through a belt. Through regulating the speed of the threshing cylinder, the defect of the single speed of the original threshing cylinder is improved to ensure that the machine body can select a proper threshing speed when working according to the difference of rice varieties and the yield of crops so that unnecessary power consumption loss is reduced, crops are threshed more cleanly, the loss rate of grains is reduced, and the adaptability of the machine body is greatly improved.

Description

technical field [0001] The invention relates to a gearbox transmission device, in particular to a three-speed transmission device for a threshing drum of a semi-feed rice and wheat combine harvester. Background technique [0002] With the development of China's agricultural modernization, the scientific and technological content of agricultural products has gradually increased, and the rice yield can reach as high as 916.44 kg / mu. Rice planting covers a large area, from Heilongjiang in the north to Hainan Island in the south, and different rice varieties are planted in different regions, the height of the grain is different, the strength of the rice straw is different, and the yield is different. Nowadays, cross-regional operations have also formed a climate. How to adapt to the development of modern agricultural production and meet market demand poses a severe challenge to the harvester industry. In the prior art, the transmission device of the semi-feeding rice and wheat ...
