Detailed Description
As shown in fig. 1, a transmission assembly 1 for a rotary cultivator includes a transmission case 12 and a transmission case 11; wherein, the transmission case 12 is used for being connected with an output shaft of the engine in a transmission way and transmitting power to a travelling mechanism and a rotary tillage head of the rotary cultivator; the transmission case 11 changes the speed of the power of the transmission case 12 and then transmits the power to the traveling mechanism.
As shown in fig. 2, in the power transmission direction, the transmission case 12 is provided with three chambers, i.e., a transmission chamber, a traveling power output chamber, and a rotary tillage power output chamber. An input shaft 124, a transmission shaft 125, a first power output shaft 121, a second power output shaft 122 and a third power output shaft 123 are arranged in the transmission case 12.
Wherein, the input shaft 124 is rotatably installed in the transmission case, and one end of the input shaft 124 extends out of the transmission case 12 and is connected with the output shaft of the engine in a transmission way; the other end of the power transmission mechanism penetrates through the transmission chamber and then extends into the traveling power output chamber. The input shaft 124 is provided with a shift gear set 1241 and a power take-off gear 1242.
The power take-off gear 1242 is located in the travel power take-off compartment and is fixedly disposed on the input shaft 124 for synchronous rotation with the input shaft 124. Specifically, the power output gear 1242 is a bevel gear fixedly disposed at an end of the input shaft 124.
One end of the third power output shaft 123 extends into the advancing power output chamber, and the other end extends out of the transmission case 12; the third power output shaft 123 is sleeved with a forward gear transmission gear 1231 and a reverse gear transmission gear 1232, both the forward gear transmission gear 1231 and the reverse gear transmission gear 1232 can rotate relative to the third power output shaft 123, and the forward gear transmission gear 1231 and the reverse gear transmission gear 1232 are meshed with the power output gear 1242 for transmission.
The traveling power output chamber is provided with a second fork shaft 127, and the second fork shaft 127 can slide along the axial direction of the transmission case 12. Two groups of shifting fork assemblies are arranged on the second shifting fork shaft 127, and the forward gear transmission gear 1231 and the reverse gear transmission gear 1232 are in transmission connection with the third power output shaft 123 respectively. Specifically, each fork assembly includes a spline housing 1271 and a second fork 1272, and the spline housing 1271 is sleeved on the third power output shaft 123, can axially slide relative to the third power output shaft 123, and synchronously rotates with the third power output shaft 123. The second fork 1272 is fixed on the second fork shaft 127, and can shift the spline housing 1271 to slide along the third power output shaft 123.
As shown in fig. 2 and fig. 3, when the rotary cultivator needs to be controlled to move forward, the second shifting fork shaft 127 is controlled to slide rightward, the spline housing 1271 corresponding to the forward gear transmission gear 1231 is clamped with the forward gear transmission gear 1231, the spline housing 1271 corresponding to the reverse gear transmission gear 1232 is separated, the forward gear transmission gear 1231 is in transmission connection with the third power output shaft 123, and the rotary cultivator moves forward. When the rotary cultivator needs to be controlled to move backwards, the second shifting fork shaft 127 slides leftwards, the spline housing 1271 corresponding to the reverse gear transmission gear 1232 is clamped with the reverse gear transmission gear 1232, the spline housing 1271 corresponding to the forward gear transmission gear 1231 is separated, the reverse gear transmission gear 1232 is in transmission connection with the third power output shaft 123, and the rotary cultivator moves backwards.
The transmission input shaft 112 is in transmission connection with the third power output shaft 123 through a transmission member such as a transmission chain or a transmission belt, so that power is transmitted from the transmission case 12 to the transmission case 11. The gearbox 11 only controls the output speed, and the power is transmitted to the travelling mechanism of the rotary cultivator through the gearbox output shaft 111.
The shift gear set 1241 is located within the drive chamber and is movable relative to the input shaft 124 in an axial direction of the input shaft 124 and rotates synchronously with the input shaft 124. A first shifting fork shaft 126 is further arranged in the transmission chamber, a first shifting fork 1261 is arranged on the first shifting fork shaft 126, and the first shifting fork 1261 pushes the shifting gear set 1241 to realize shifting.
The input shaft 124 and the drive shaft 125 are arranged in parallel, and the drive shaft 125 is used to transmit power to the rotary tillage head. The transmission shaft 125 is fixedly provided with a low-speed transmission gear 1251 and a high-speed transmission gear 1252, and the low-speed transmission gear 1251 and the high-speed transmission gear 1252 are both positioned in the transmission chamber. The low-speed transmission gear 1251, the high-speed transmission gear 1252 and the transmission shaft 125 can be integrally formed or can be assembled by separate processing. Low-speed or high-speed output can be realized by controlling the gear shifting gear set 1241 to be meshed with the low-speed transmission gear 1251 or the high-speed transmission gear 1252; of course, when the shift gear set 1241 is between the low and high transfer gears 1251 and 1252 and is not engaged with the low and high transfer gears 1251 and 1252, the tiller head has no power input.
One of the first power output shaft 121 and the second power output shaft 122 is low speed output and the other is high speed output. The first power output shaft 121 or the second power output shaft 122 can be selected to output power to the rotary cultivator. When in use, the rotary tillage head can be selectively connected with the first power output shaft 121 or the second power output shaft 122 through a universal joint in a transmission way.
Specifically, the first power output shaft 121 and the transmission shaft 125 are coaxially arranged and in transmission connection, specifically, one end of the first power output shaft 121 extends into the traveling power output chamber, and is in transmission connection with the transmission shaft 125 through structures such as a coupler and a shaft sleeve; the first power output shaft 121 and the transmission shaft 125 may be integrally formed. The other end of the first power output shaft 121 passes through the rotary tillage power output chamber and then extends out of the transmission case 12, and can be in transmission connection with the rotary tillage head through a coupler.
The second power output shaft 122 is rotatably disposed in the rotary tillage power output chamber, and one end of the second power output shaft extends out of the transmission case 12 and can be in transmission connection with the rotary tillage head through a coupler. An output transmission driving gear 1211 is fixedly arranged on the first power output shaft 121, and an output transmission driven gear 1221 is fixedly arranged on the second power output shaft 122; the output transmission driving gear 1211 and the output transmission driven gear 1221 are both located in the rotary tillage power output chamber. The output transmission driving gear 1211 is engaged with the output transmission driven gear 1221 to transmit power from the first power output shaft 121 to the second power output shaft 122.
Since the tilling head needs to swing, in order to avoid the influence on the transmission element from the first power output shaft 121 to the second power output shaft 122, it is preferable that the two end faces of the output transmission driving gear 1211 and the output transmission driven gear 1221 are positioned by using self-aligning thrust roller bearings.
