Description

Novel transmission case for rice transplanter

Technical Field

The utility model relates to a transplanter field especially relates to a novel transmission case for rice transplanter.

Background

In the rice planting process, a rice transplanter is often used for transplanting rice seedlings, and a transmission shaft and a transmission case of the rice transplanter are easily corroded due to the working environment of the rice transplanter being a paddy field, so the transmission case is often closed, but the sealing of a bearing cover at the end part of the transmission shaft is often not tight enough, sludge is easily invaded to damage a single-side bearing, the service life is influenced, and the structure is not reasonable enough.

SUMMERY OF THE UTILITY MODEL

The utility model provides a novel transmission case for rice transplanter with reasonable structure, which aims at the defects existing in the prior art.

The utility model aims at realizing through the following technical scheme:

a novel transmission case for a rice transplanter comprises a bearing end cover, a transmission case, a transmission shaft and a first sealing ring, wherein the end part of the bearing end cover is provided with an end plate, a thread groove is formed in the end plate, the outer side of the end plate is provided with a light shaft section, a sleeve groove is formed in the light shaft section, a thread column is arranged on the outer side of the light shaft section, a bearing chuck is arranged on the outer side of the thread column, a connecting groove is formed in the transmission case, a first sealing ring groove is formed in the connecting groove, a second sealing ring groove is formed in the inner side of the first sealing ring groove, a light shaft groove is formed in the inner side of the second sealing ring groove, a thread column groove is formed in the inner side of the light shaft groove, a bearing clamping groove is formed in the inner side of the thread column groove, the first sealing ring is placed in the first sealing ring groove, the second sealing ring is placed in the second, the shaft shoulder is clamped with the outer edge of the bearing inner ring.

The bearing end cover is externally provided with a thread groove, a knurled thread column is in threaded connection with the thread groove, the thread column is in threaded connection with the thread column groove, the bearing end cover is connected with the transmission case, and the end part of the bearing chuck is clamped with the bearing outer ring.

Has the advantages that:

o type sealing ring cup joints with the grooving, a sealing washer inslot is put into to the sealing washer, No. two sealing washers are put into No. two sealing washer inslots, it cooperates mutually and forms triple airtight mechanism, reduce the possibility of external silt and air invasion, a sealing washer, No. two sealing washers, O type sealing ring cross-section is circular, the spacing deformation in pressfitting power and the smooth shaft groove that receives the end plate, can make sealed more inseparable, only need during the dismouting with annular knurl thread post and thread groove spiro union, thereby make thread post groove close soon with the thread post or unscrew, the dismouting of being convenient for, rational in infrastructure.
