Abstract
A small rotary cultivator transmission with two power output shafts is composed of a gearbox and a transmission box. A power input shaft, a gear shaft of gears, a backward gear shaft and a fork shifting shaft are installed in the gearbox. A large sliding gear and a small sliding gear are sleeved on the power input shaft. A first-gear gear, a second-gear gear and a third-gear gear are arranged on the gear shaft of gears. A main transmission shaft, a first output shaft and a second output shaft are installed in the transmission box, a variable gear on the main transmission shaft is meshed with a backward gear, a variable gear on the first output shaft is meshed with the variable gear on the main transmission shaft, and a normal gear on the second output shaft is meshed with the variable gear on the first output shaft. By adjusting speed ratios of the gears, the output rotating speed of the first output shaft can be increased, and the rotating speed of the second output shaft can be reduced. When the transmission is used in running, wheels are installed on the first output shaft to increase vehicle speed. When the transmission is used for cultivation, an agricultural tool is installed on the second output shaft to reduce speed and increase power. Therefore, the small rotary cultivator transmission is convenient to use for both running and cultivation.

Because the gearbox of said structure only has three-step gear shift, no matter when being used for farming or travelling, output speed and the dynamic range of each gear are more fixing, use its speed of high tap position still slower when travelling, and power waste is big, oil consumption is high; Use lowest gear during farming, operator's speed still is difficult to catch up with its forward velocity, and operation is used very inconvenient.
Summary of the invention
For solving the gearbox that exists in the prior art three-step gear shift is only arranged, be used for travelling and speed and dynamic range unreasonable distribution during farming, cause and use its speed of high tap position still slower when travelling, power waste is big, oil consumption is high; Use lowest gear during farming, operator's speed still is difficult to catch up with its forward velocity, very inconvenient problem is used in operation, the invention provides a kind of small-sized speed transmission for rotary tillage machine of double dynamical output shaft, this speed changer is made up of gearbox and transmission case two-part, transmission case is installed in the gearbox below, power input shaft is housed in the gearbox, power input shaft one end stretches out outside the gearbox, other grade gear shaft and the reverse gear axle of being equipped with of power input shaft, power input shaft, shelves gear shaft and the reverse gear axle is triangular in shape arranges, the power input shaft top is equipped with first declutch shift shaft and second declutch shift shaft, is movably installed with little sliding gear and big sliding gear on the power input shaft; At the shelves gear shaft one grade of gear, intermediate gear and three-range transmission are installed; At the reverse gear axle reverse gear and continuously-meshing gear are installed, reverse gear is two fixing speed change gears of forming of gear that diameter is different, continuously-meshing gear and three-range transmission fixed engagement; First shift fork of one grade and reverse gear is installed at first declutch shift shaft, second shift fork of second gear and third gear is installed at second declutch shift shaft, little driving lever on first shift fork inserts in the gap of little sliding gear, big driving lever on second shift fork inserts in the gap of big sliding gear, one end of shift level stretches in the gearbox, and dial between the plate first shift fork and second shift fork the termination; In transmission case, main drive shaft, first output shaft and second output shaft are installed, the main drive shaft speed change gear is installed on the main drive shaft, main drive shaft speed change gear and reverse gear engagement, at first output shaft first output shaft speed change gear is installed, the first output shaft speed change gear and the engagement of main drive shaft speed change gear are equipped with the normal gear of second output shaft at second output shaft, the normal gear of second output shaft and the engagement of the first output shaft speed change gear.
Adopt technique scheme, by adjusting the speed ratio of respectively organizing gear, the rotating speed of the output on the microtilling machine output shaft in the rotating ratio prior art on first output shaft is increased, the rotating speed of the output on the microtilling machine output shaft in the rotating ratio prior art on second output shaft is reduced, like this, when the speed changer of microtilling machine when being used for travelling, wheel is installed on first output shaft, first output shaft is through three-step gear shift, rotating speed is very fast relatively, and microtilling machine can obtain travelling speed faster, when speed changer is used for farming, the agro-farming equipment is equipped with on second output shaft, second output shaft is through the level Four speed change, and rotating speed is relatively low, and outputting power is big, operator's speed can be caught up with the forward velocity of microtilling machine fully, and operator can easily control microtilling machine.
For reducing the volume of transmission case, machine volume is reduced, can be triangle with the Position Design of three axles in the transmission case of the present invention, to reduce the transmission case volume.
