Problems solved by technology

[0003] 1. The internal structure and transmission relationship of the gearbox of the existing sprayer are complicated, and the output torque and speed range of the gearbox are narrow, which cannot meet the needs of different working conditions of walking and working
[0004] 2. The size of the gearbox is large, the installation is inconvenient, and the applicability is poor
[0005] 3. Only one output shaft, single function, narrow scope of application
[0006] 4. In the prior art, the gearbox is connected to the engine through the connecting flange and the connecting transmission shaft, which is noisy and takes up a lot of space for assembly and installation. The use of the gearbox is limited, so that the layout of the whole vehicle is not compact enough.
[0007] 5. It is inconvenient to lubricate the upper part of the gearbox, the lubrication effect is poor, and the service life of the parts is short
[0008] 6. The internal structure of the gearbox is complicated, the number of parts is large, and the versatility of the parts is poor, the assembly process is complicated and the cost is high
[0009] 7. The operation of shifting gears is complicated. The position of the shaft gear is changed by the gear lever to achieve the meshing and separation of different gears, and the change of the gear position is realized. The frictional resistance is large; during the gear shifting operation, the gearbox operation is time-consuming and laborious, and the position of the gear lever limits the speed change box installation location
[0010] In summary, there are obviously inconveniences and defects in the actual use of the existing technology, so it is necessary to improve

Abstract

The invention discloses a gearbox for a spraying machine. The gearbox comprises a box body which is internally provided with a power input shaft, a first transmission shaft, a second transmission shaft, a third transmission shaft and a power output shaft; the power output shaft is fixedly provided with a first gear; the first transmission shaft is provided with a second gear, a reverse sliding sleeve and a reverse gear; the second transmission shaft is provided with a third gear, a fourth gear, a second sliding sleeve, a fifth gear, a first sliding sleeve and a sixth gear; the third transmission shaft is fixedly provided with a ninth gear, a eighth gear and a seventh gear; and the power output shaft is slidably provided with a duplex gear. The gearbox can meet the walking condition and theworking condition and is good in applicability, and application of the gearbox can be wider; the structure of the gearbox is compact, and noise is low; the gearbox can achieve self lubrication, and the part universality of the gearbox can be improved; and the gearbox can achieve gear engaging operation easily, gear disengagement is not prone to occurring, and the gearbox can achieve gear engagingthrough a flexible shaft.

Description

technical field [0001] The invention relates to a gearbox, in particular to a gearbox for a sprayer, which belongs to the technical field of gearboxes for rural plant protection machinery, and can also be used for other small agricultural and construction machinery such as seedling transporters and road rollers. Background technique [0002] The gearbox of the existing sprayer is generally a gearbox for a small loader or a road roller. In practical applications, the gearbox has the following technical defects: [0003] 1. The internal structure and transmission relationship of the gearbox of the existing sprayer are complicated, and the output torque and speed range of the gearbox are narrow, which cannot meet the needs of different working conditions of walking and working. [0004] 2. The gearbox is large in size, inconvenient to install and poor in applicability. [0005] 3. There is only one output shaft with single function and narrow application range. [0006] 4. In...
