Problems solved by technology

However, relying only on the power provided by the rear wheels makes the power of the fifth wheel less when turning. When the soil is soft or the ground is muddy, the wheels are prone to slipping, the turning power is insufficient, the efficiency is low, and the safety performance is poor.

[0022] figure 1 and figure 2 As shown, the present invention relates to a tractor that can select the rotation speed of the fifth wheel 106 in multiple gears, including a tractor, the tractor is equipped with an engine, a clutch, a five-wheel gearbox, the fifth wheel 106 and a lifting device.

[0023] The five-wheel gearbox includes an input shaft 101 , a reverse intermediate shaft 102 , an output intermediate shaft 105 , a rear output shaft 103 and a front output shaft 104 . A reverse drive gear 111 , a high-grade drive gear 112 and a low-gear drive gear 113 are installed on the input shaft 101 . A reverse intermediate gear 121 meshing with the reverse drive gear 111 is mounted on the reverse intermediate shaft 102 . The rear output shaft 103 is equipped with a gear shift driving gear 138 and a reverse driven gear 131, a high gear driven gear 131, a high gear driven gear 131, and a high gear driven gear that are meshed with the reverse intermediate gear 121, the high gear ...

[0032] The structure of the second embodiment of the present invention is basically the same as that of the first embodiment except that the third engaging sleeve 142 , the splined hub 146 and the fourth engaging sleeve 143 are different in installation position and function mode. The difference is that: image 3 As shown, the front end of the rear output shaft 103 and the rear end of the front output shaft 104 are respectively equipped with spline hubs 146. When on the hub 146, it is all located on the splined hub 146 at the front end of the rear output shaft 103, the connection between the rear output shaft 103 and the front output shaft 104 is disconnected; the third engaging sleeve 142 moves forward When it reaches the spline hub 146 at the rear end of the front output shaft 104, a part of it is still engaged with the spline hub 146 at the front end of the rear output shaft 103, that is, when the third engaging sleeve 142 moves forward, the rear The output shaft 103 is co...

Abstract

The invention relates to the field of agricultural machinery, in particular to a tractor capable of selection of a fifth wheel speed in multiple gears. The tractor is internally provided with an engine, a clutch, a fifth wheel, a five-wheel gearbox and a lifting device, wherein the five-wheel gearbox comprises an input shaft, a reverse intermediate shaft, an output intermediate shaft, a rear output shaft and a front output shaft; a reverse drive gear wheel, a high-end drive gear wheel and a low-end drive gear wheel are installed on the input shaft; a reverse intermediate gear wheel is installed on the reverse intermediate shaft; a shifting drive gear wheel, a reverse driven gear wheel, a high-end driven gear wheel and a low-end driven gear wheel are equipped on the rear output shaft; a shifting driven gear wheel is installed on the front output shaft, a first shifting intermediate gear wheel and a second shifting intermediate gear wheel are installed on the output intermediate shaft, the front end of the rear output shaft is connected to or disconnected from the rear end of the front output shaft through a third meshing sleeve, and one side of the shifting driven gear wheel is provided with a fourth meshing sleeve linked with the third meshing sleeve. The tractor provided by the invention has the advantages of convenient operation, high working efficiency, safety and reliability.

Description

technical field [0001] The invention relates to the field of agricultural machinery, in particular to a tractor which can select the rotation speed of the fifth wheel in multiple gears. Background technique [0002] As an important agricultural implement, a tractor usually needs to turn at the head of the field when it is mounted with a rear-mounted agricultural tool for operation. However, the four-wheel tractors in the prior art have a large turning radius and low operating efficiency when turning. In view of the above problems, in real work, many people artificially modify the four-wheel tractor, just add a fifth wheel in front of the vehicle, use the lifting device to lift and lower the fifth wheel, when the fifth wheel needs to turn , relying on the driving force of the rear wheels to force the fifth wheel to turn and turn the tractor around. However, only relying on the rear wheels to provide power makes the fifth wheel less powerful when turning. When the soil is rel...
