Abstract
The utility model discloses an improved harvester transmission driving box which comprises a driving box body case, a power take-off shaft which vertically projects up from the driving box body case and is also fixedly connected with a vertical lift screw conveyer, an impurity discharge wheel arranged on the shaft body of the power take-off shaft between the vertical lift screw conveyer and the driving box body case, and an impurity discharge cover with holes which is arranged around the impurity discharge wheel and separates the impurity discharge wheel from surroundings. The arrangement of the impurity discharge wheel and the impurity discharge cover with holes effectively prevents impurities such as clay, dust and crushed glumes from entering the driving box, thereby greatly improving the life-span of the driving box and reducing the machine operation failure rate.
Description
Technical field
The utility model relates to improved reaper and carries transmission case.
Background technique
Present rice combine conveying box, comprise mechanism housing, stretch out the pto that described mechanism housing is outer and fixedly connected with vertical elevator screw feeder vertically upward, during harvest operation, seed under the results is often wrapped up in band earth, dust, impurity such as clever shell in small, broken bits, and seed is carried the sealing effect that the seal arrangement of transmission case does not reach under this kind condition, earth, dust, impurity such as clever shell in small, broken bits enter and cause the transmission case inner bearing in the transmission case, transmission components such as gear damage in early days, and improve the machinery operation rate of fault, cause reaper to carry transmission case to reduce working life.
Summary of the invention
Technical problem to be solved in the utility model provide a kind of transmission case seal arrangement good, impurity such as earth dust and clever shell in small, broken bits can not enter transmission case, improve transmission case improved reaper working life, that reduce the machinery operation rate of fault greatly and carry transmission case.
For achieving the above object, the technical solution of the utility model is: improved reaper is carried transmission case, comprise mechanism housing, stretch out the pto that described mechanism housing is outer and fixedly connected with vertical elevator screw feeder vertically upward, described pto vertically is being fixed with and can taking turns with the impurities removal of pto rotation on the axle body between elevator screw feeder and the mechanism housing.
As a kind of improvement, the periphery of described impurities removal wheel is provided with impurities removal wheel and the extraneous impurities removal cover of separating with holes.
Owing to adopt technique scheme, improved reaper is carried transmission case, comprise mechanism housing, stretch out the pto that described mechanism housing is outer and fixedly connected with vertical elevator screw feeder vertically upward, described pto vertically is being fixed with and can taking turns with the impurities removal of pto rotation on the axle body between elevator screw feeder and the mechanism housing, pto drives the rotation of impurities removal wheel, can be having earth in the seed, impurity such as dust and clever shell in small, broken bits is got rid of beyond transmission case, thereby improves transmission case working life greatly and reduce the machinery operation rate of fault.
Another advantage of the present utility model is, the periphery of described impurities removal wheel is provided with impurities removal wheel and the extraneous impurities removal cover of separating with holes, impurities removal cover with holes can effectively stop impurity such as earth, dust and clever shell in small, broken bits to enter in the transmission case, and, the impurity such as earth, dust and clever shell in small, broken bits that enter in the impurities removal cover with holes can be discharged the impurities removal cover by aperture on the impurities removal cover by the impurities removal wheel with the pto rotation, thereby improve transmission case working life greatly and reduce the machinery operation rate of fault.
Description of drawings
Accompanying drawing is the utility model embodiment's a structural representation.
Embodiment
As shown in drawings, improved reaper is carried transmission case, comprise mechanism housing 1, stretch out outside the described mechanism housing 1 vertically upward and the pto 3 of fixedlying connected with vertical elevator screw feeder 2, described pto 3 vertically is being fixed with and can taking turns 4 with the impurities removal of pto 3 rotations on the axle body between elevator screw feeder 2 and the mechanism housing 1, and the periphery of described impurities removal wheel 4 is provided with the with holes impurities removal cover 5 of impurities removal wheel 4 with extraneous separation.
Working principle of the present utility model is: reaper is carried in the seed that transports in the transmission case can have impurity such as earth, dust and clever shell in small, broken bits, these impurity are subjected to impurities removal and take turns stopping of 4 top cover plates 6, promptly can not enter reaper carries in the transmission case, thereby protected reaper to carry transmission case, improved transmission case working life greatly and reduce the machinery operation fault; Because of pto 3 drives 4 rotations of impurities removal wheel, impurities removal wheel 4 can effectively be discharged impurities removal cover 5 to the impurity such as earth, dust and clever shell in small, broken bits that enter on the impurities removal wheel 4 by the aperture on the impurities removal cover 5 with holes, and impurities removal cover with holes 5 has also played stop impurity such as earth, dust and clever shell in small, broken bits to enter the effect of carrying in the transmission case simultaneously, thereby improves transmission case working life greatly and reduce the machinery operation fault; Play an important role to improving transmission case working life and reducing the machinery operation rate of fault equally.
As from the foregoing, transmission case of the present utility model, seal arrangement is good, can effectively stop impurity such as earth dust and clever shell in small, broken bits to enter transmission case, and improve the working life of transmission case greatly, has reduced the machinery operation rate of fault.
