Transmission box with gear clutch

Abstract

The invention provides a transmission box with a gear clutch, particularly a transmission box for transferring power to a hitching gearbox of an agricultural implement, belonging to the components of agricultural machinery. The transmission box comprises a box body, an input shaft, an output shaft, a driving wheel and a driven wheel, wherein the input shaft and the output shaft are mounted on the box body, the driving wheel is arranged on the input shaft and the driven wheel is arranged on the output shaft. The transmission box is characterized in that a gear clutch is arranged on the output shaft and near to one end outside the transmission box. The transmission box is beneficial to the power distribution of the hitching gearbox of the agricultural implement, can be used in paddy field and upland field, is free from clamp, slide and component damage, runs stably and is less impacted when being meshed.

Description

technical field [0001] The invention relates to a component of an agricultural machine, in particular to a transmission box for transmitting power to an agricultural machine coupled with a gear box. Background technique [0002] In the transmission mechanism of the existing tractor, it is usually a belt pulley that transmits power to the gearbox connected to the agricultural implement, and the clutch of the transmission mechanism usually adopts two kinds of ten-type clutch or wet clutch. If a dry clutch is used, it is usually installed on the pulley and combined into a pulley clutch; if a wet clutch is used, it is usually installed on the transmission shaft of the gearbox. In the actual production and use process, we found that they all have certain defects. For example: Avoid oil, water, and dust in dry clutches. Once soaked in oil and water, the clutch will slip, and if it is polluted by dust, the clutch will be stuck and cannot work normally, and the pulley transmission ...

AI Technical Summary

Problems solved by technology

For example: Avoid oil, water, and dust in dry clutches. Once soaked in oil and water, the clutch will slip, and if it is polluted by dust, the clutch will be stuck and cannot work normally, and the pulley transmission mechanism is open or half-open. It is inevitable to be polluted by dust in the process of agricultural machinery operation, and the pulley clutch cannot be used for paddy field operations; wet clutches can be used for clutches in paddy field operations, but they have higher requirements on the oil condition in the clutch and are indispensable. Oil, otherwise the operation will be interrupted, causing damage to the equipment and other components, and the wet clutch is installed on the transmission shaft of the gearbox directly connected to the agricultural machinery, which increases the volume of the gearbox to a certain extent

The clutch method of the micro tillage machine usually uses the tensioner wheel to realize the clutch. The defect of this clutch method is that the belt is easy to wear and slip when it encounters water, so once the belt is worn or the clutch encounters water, the clutch will not achieve the clutch effect.
