Abstract
The utility model discloses a gear box assembly of a stubble cleaner. A gear box is additionally provided with a spline shaft (14), a traveling gear (13), a shifting fork shaft (11), and a shifting fork (19) inside; a shifting fork lever 35 and the shifting fork shaft (11) are driven by a handle which is arranged beside an operator to drive the shifting fork (19) to shift the traveling gear (13); power is cut off or switched on by the engaging and the disengaging of the traveling gear (13) and a driving gear (15) on a shaft (7). The utility model has convenient operation, ensuring the safety of operators, tractors and tools, cancelling engaging and disengaging device on a belt wheel of an output shaft of the tractor, reducing weight, and eliminating fit clearance, and thus the rotation of the utility model is stable; a belt does not fall off in long-term use, extending the service life of the output shaft of the tractor.
Description
The utility model relates to a kind of gear drive of stubble cleaner.
The gear drive box assembly of present stubble cleaner, because tractor output shaft is short and small, load onto the clutch pulley arm length, overweight, because of slide units such as assembling clutch tooth embeddings in the belt pulley, the imbalance by the free gap causes belt pulley to rotate causes yaw again, the long-term swing gap of using is strengthened, and belt easily comes off.Clutch handle is located on the movement parts, operates very inconvenient.
The purpose of this utility model provides a kind of weight that alleviates the tractor output shaft belt pulley, eliminates fit clearance, makes the running of output shaft steady, uses belt not come off for a long time.Clutch handle is located on the fixture, is installed in the operator at one's side by lever, easy to operate gear drive box assembly.
The purpose of this utility model is achieved in that sets up splined shaft in transmission case, the slip location of travelling gear, declutch shift shaft, shift fork, declutch shift shaft and the fixed position of shift fork, the shifting lever handle, drive lever by devices such as balance pivot and shift forks, cut off power by gears to engage and disengage, arrangement of clutch on the cancellation tractor belt wheel, alleviated the weight of belt pulley, eliminated the fit clearance of belt pulley slides within part, belt pulley operates steadily, the long-term belt that uses does not come off, and has prolonged the service life of tractor output shaft.Shift fork is by lever, fulcrum and handle, and the fitting operation person at one's side, and is easy to operate, runs into obstacle in the operation, can cut off the power of tractor and transmission case at any time, and operation has in time guaranteed the operator, the safety of tractor and facility.
This transmission case assembly is owing to the arrangement of clutch of having cancelled on the tractor belt wheel, cut off power by gears to engage and disengage, alleviated the weight of belt pulley, eliminate the fit clearance of belt pulley slides within part, belt pulley is operated steadily, use belt not come off for a long time, prolonged the life-span of tractor output shaft, clutch handle is installed in the power that the operator can cut off tractor and transmission case at one's side at any time, and is easy to operate, timely, guaranteed the safety of operator, tractor and facility.
Below in conjunction with description of drawings embodiment:
Fig. 1 is the outline drawing of stubble cleaner gear drive box assembly;
Fig. 2 is the A-A revolved sectional view of Fig. 1
Fig. 3 is the B-B cutaway view of Fig. 1
1,2,3 when installing as can be known with reference to the accompanying drawings, the driving gear 15 of gear is contained on one 7, be fixed on the casing 1 by 2 bearings 26 for one 7, passive balladeur train 13 and drive sprocket 18 are contained on the splined shaft 14, splined shaft 14 is installed on the casing 1 by 2 bearings 26, is fixed on the casing 1 by one 7 end cap 17.Be contained on the rotary tillage shaft 3 by movable sprocket 10, in the hole of casing 1, locate, be fixed on the casing 1 by two glands 2 again by spacer 8 and two bearings 22.The shift fork 19 of balladeur train 13 is contained on the declutch shift shaft 11, and declutch shift shaft 11 is fixed on the casing 1 by box body hole, and declutch shift shaft one end is connected with shifting fork bar 35 by coin bolt 24, and shift fork is stuck in the dovetail groove of carrier wheel 13, has adorned the back and has sealed with pressing plate 4.Plug cock 34 injects the lubricating oil rear enclosed.During work, power drives belt pulley on one of the transmission case by 4 belts of tractor output shaft belt pulley, driving gear 15 by assembling on one 7 drives carrier wheels 13 rotations, carrier wheel 13 can slide on splined shaft 14, carrier wheel 13, drive splined shaft 14 rotations and drive drive sprocket 18 rotations that are fixed on the splined shaft 14, drive sprocket 18 drives sprocket wheel 10 by chain and rotary tillage shaft 3 rotates, and the rotary tillage cutter that is fixed on the rotary tillage shaft 3 can carry out the work of rotary tillage stubble-cleaning.
When running into obstacle and need cut off power, by stirring handle, drive shifting fork bar 35, horizontally slip in casing 1 by declutch shift shaft 11, when driving shift fork 19 carrier wheel 13 being slided into anchor point to the right, cuts off the power of one 7 and splined shaft 14, the power of tractor output shaft only drives one 7 rotation, other parts of transmission case all quit work, and the operation of rotary tillage stubble-cleaning stops.When work, when stirring handle and driving declutch shift shafts 11 shift forks 19 13 groups of carrier wheels arrive anchor point left by shifting fork bar 35, balladeur train 13 meshes with driving gear 15 on one 7, and soon power passes to and carries out the operation of rotary tillage stubble-cleaning on the rotary tillage shaft.
Claims (2)
1, a kind of stubble cleaner gear drive box assembly, form by following each several part: by casing (1), be installed in (7) on the casing (1) and be installed in a driving gear (15) on (7), splined shaft (14), be installed in the drive sprocket (18) on the splined shaft (14), carrier wheel (13), rotary tillage shaft (3) and be installed on the rotary tillage shaft (3) by movable sprocket (10), be installed in the shift fork (19) on the declutch shift shaft (11), the other end of declutch shift shaft (11) is connected with shifting fork bar (35) by bolt (24), it is characterized in that carrier wheel (13) is installed on the splined shaft (14).
