The utility model purpose be to provide a kind of can with can be used for field irrigation and extract the flexible axle pump of mud, mortar of multiple power adapted.
For reaching above-mentioned purpose, the utility model adopts following technological scheme: a kind of flexible axle pump, comprise that belt pulley, belt pulley and anti-reversing driving mechanism transmission axle key connect, transmission shaft lower end and water pump or shell pump propeller shaft couplings, anti-reversing driving mechanism transmission shaft lower end and flexible axle upper end socket, flexible axle lower end and water pump or the socket of shell pump transmission shaft; Flexible axle has the flexible axle sleeve pipe outward, and flexible axle sleeve pipe upper and lower end is connected with water pump or shell pump driving mechanism housing with anti-reversing driving mechanism housing respectively.
Anti-reversing driving mechanism comprises cylindrical shell and the transmission beam barrel and the transmission shaft that are loaded in the housing tube, is provided with bearing between transmission shaft drum outer wall and the housing, and the transmission beam barrel is connected with pulley key; The transmission shaft side axial has the anti-down turn trough of an involute, and the anti-down turn key of Pei Heing passes that keyhole connects with keyhole on the belt pulley on the transmission beam barrel with it.
Belt pulley upper and lower end center hole has the circumferential groove that communicates with anti-down turn key groove outward, is with anti-down turn key Returnning spring in the groove.
Transmission shaft and flexible axle connecting end are square column type, and flexible axle and transmission shaft connecting end are round outside but spuare inside connecting sleeve.
Transmission shaft and flexible axle connecting end are round outside but spuare inside connecting sleeve, and flexible axle and transmission shaft connecting end are square column type.
Between anti-reversing driving mechanism and pump housing driving mechanism, there are some flexible axles to be connected, two mutual sockets in flexible axle termination up and down; Flexible axle is outer also to be coupled to each other between two sleeve pipes up and down.
Fig. 1 is belt pulley and anti-reversing driving mechanism transmission beam barrel, transmission shaft annexation and structural representation;
Fig. 2 is the flexible axle structural representation;
Fig. 3 is belt pulley and anti-reversing driving mechanism and flexible axle, flexible axle sleeve pipe annexation and structural representation;
Fig. 4 is flexible axle, flexible axle sleeve pipe and water pump annexation and structural representation;
Fig. 5 is flexible axle, flexible axle sleeve pipe and shell pump annexation and structural representation.
The utility model is flexible axle and pump housing propeller shaft couplings, flexible axle length can be adjusted according to the water level depth, available 1 flexible axle, also available 2 above flexible axle end socket lengthenings (flexible axle one end is rectangular cylindricality at this moment, end is round outside but spuare inside connecting sleeve in addition), thereby not limited by the water level depth, lift is improved; From the power of motor, diesel engine etc. all can with the belt pulley adapted, adaptability is strong; The pump housing that links to each other with the flexible axle lower end can be water pump, also can change slurry pump, mortar pump as required into, not only can be used for the farmland pumping irrigation but also can be used for mud and mortar extracts, and is applied widely; The hose end connecting sleeve adopts round outside but spuare inside design, both can guarantee the interlock between flexible axle and transmission shaft, flexible pipe and the flexible axle, can avoid again because of with the defective of the friction lifetime of flexible shaft protecting inner tube wall; In the anti-reversing driving mechanism,, solved the anti-reversing problem of transmission shaft simply, dexterously along the anti-down turn trough of involute shape of transmission shaft surface axial design and the setting of anti-down turn key.
Further specify the utility model below in conjunction with accompanying drawing by embodiment.
