Speed-up reversing box with functions of reversing and overpassing

Abstract

The invention provides a speed-up reversing box with functions of reversing and overpassing. When users back a tractor, the power provided by tractor power output is capable of overpassing interruption through a speed-up reversing gearbox to avoid blades wear damage of agricultural implements. The speed-up reversing box includes an input shaft and an output shaft, a top end of the input shaft is fixedly sleeved with a driving bevel gear, and the central part of the output shaft is sleeved with a driven bevel gear. The driving bevel gear is engaged with the driven bevel gear, and a reversing overpassing clutch structure is arranged on the race between the driven bevel gear and the output shaft. The mating relationship between a original power output shaft and the driven bevel gear is changed, a reversing overpassing structure with simple structure is arranged between the original power output shaft and the driven bevel gear, so that the output shaft can only one-way match and rotate with the driven bevel gear, and wheels of the driven gear hitting the gears of the input shaft is prevented after the turn-over of the output shaft. According to the speed-up reversing box with functionsof reversing and overpassing, the operation is simple and at the same time the work efficiency is improved when a tractor drives the agricultural implements to work.

Description

technical field [0001] The invention relates to the field of mechanical transmission in agricultural machinery, in particular to a speed-increasing reversing box with reverse overrunning function. Background technique [0002] Agricultural implements are machines for tidying up the fields. In tidying up the fields, including turning the ground, it is necessary to use tractors to drive the agricultural implements to run. The widely used power output of tractors and the transmission connection between agricultural implements are rigid direct connections. Among them, the drive from the tractor An input shaft is drawn out from the wheel to carry out mechanical transmission with the agricultural machinery. In the process of turning the ground, the turning blades of the agricultural implements turn the ground in the soil. When the tractor needs to turn around or reverse, it is necessary to lift the agricultural implements and wait for the turning blades of the agricultural impleme...

Problems solved by technology

In the process of turning the ground, the turning blades of the agricultural implements turn the ground in the soil. When the tractor needs to turn around or reverse, it is necessary to lift the agricultural implements and wait for the turning blades of the agricultural implements to separate from the soil. Then make a U-turn or reverse the car, otherwise, when the turning blades of the agricultural machinery are turned upside down in the soil, the rotation direction of the input shaft remains unchanged, and the agricultural machinery has not been completely disengaged in the soil, and the forward and reverse interference will cause the agricultural machinery to be damaged. Hit the knife

If the tractor is lifted up and then reversing, the reversing time will be delayed and work efficiency will be reduced
