Transmission case of rice transplanter

Abstract

The invention discloses a transmission case of a rice transplanter. The transmission case of the rice transplanter comprises a case body and a case cover, a gearbox output transition shaft system, a land leveling wheel output shaft system and a fertilization output shaft system are arranged between the case body and the case cover, and the gearbox output transition shaft system, the land leveling wheel output shaft system and the fertilization output shaft system are sequentially connected in a meshed mode. The land leveling wheel output shaft system is further connected with a clutch device, and the clutch device controls power output of the land leveling wheel output shaft system and power output of the fertilization output shaft system at the same time. According to the transmission case of the rice transplanter, transmission structures of the land leveling wheel output shaft system and the fertilization output shaft system are combined together, an independent land leveling wheel transmission case is omitted, power output of a land leveling wheel and a fertilization device is simultaneously controlled by using one clutch device, and the transmission structures are greatly simplified.

Description

technical field [0001] The invention belongs to the field of rice transplanter equipment, and in particular relates to a transmission box of a rice transplanter. Background technique [0002] At present, there are many kinds of optional devices for rice transplanters in China. Take the common leveling wheel device as an example: the leveling wheel device can provide power through the output of the side rice transplanting box, and can also provide power through the output of the rear axle. However, the leveling wheel device has the following problems in obtaining power: (1) when the leveling wheel device provides power through the output of the side rice transplanting box, on the one hand, it is necessary to increase the transmission box at the output position of the side rice transplanting box, which causes the rice transplanter to move left and right. There is a difference in weight on both sides, which easily affects the balance of the rice transplanter. On the other hand,...

Problems solved by technology

However, the leveling wheel device has the following problems in obtaining power: (1) when the leveling wheel device provides power through the output of the side rice transplanting box, on the one hand, it is necessary to increase the transmission box at the output position of the side rice transplanting box, which causes the rice transplanter to move left and right. There is a difference in weight on both sides, which easily affects the balance of the rice transplanter. On the other hand, the power is transmitted from one side of the rice transplanting box, and the length of the flat wheel device is longer, resulting in excessive torque and unstable transmission performance; (2) Flat wheel When the device provides power through the output of the rear axle, on the one hand, an additional clutch device is required, which has a complicated structure. On the other hand, the position of the rear axle of the rice transplanter is relatively low, and the clutch device of the flat wheel device is prone to damage during the working process, which affects normal work.
