Gear Movement Group for Grease Irrigation

A gear movement group for grease irrigation, comprising:

• a main housing having a front end and a rear end;
• a transmission assembly disposed inside the main housing;
• a gear housing and a gear cover disposed inside the main housing;
• wherein,
• the main housing is composed of a main body and a housing cover which are hermetically connected to each other, the main housing has a water inlet and a water outlet respectively located at the front end and the rear end of the main housing;
• the gear housing and the gear cover are hermetically connected to each other to define an oil-added chamber between the gear housing and the gear cover, the transmission assembly is disposed inside the oil-added chamber;
• a water inlet pipe having an inner end is disposed at the water inlet of the main housing and the inner end of the water inlet pipe extends into the main housing, and a toothed shaft at the inner end of the water inlet pipe is in transmission connection to the transmission assembly;
• a water chamber is defined inside the main housing adjacent to the water outlet, an impeller disposed inside the water chamber is in transmission connected to the transmission assembly via a gear shaft;
• a water inlet mechanism for communicating the water inlet pipe with the water chamber is disposed inside the main housing, the water inlet mechanism comprises a swayable water inlet paddle, a base located inside the main body, two hollow water inlet columns disposed axially at an inner side of the base away from the gear housing, a U-shaped support seat disposed between the two water inlet columns for allowing the water inlet paddle to reset against and tilt laterally, and a control lever being inserted into a mounting hole which is formed at the housing cover at a position corresponding to a position of the water inlet paddle;
• each water inlet column has a top opening and has a water outlet hole at a rear end of the water inlet column, the water inlet paddle has a left end and a right end which are respectively located above the top opening of each respective water inlet column;
• the water inlet mechanism further comprise a rotatable head with an arc-shaped bottom resisting against the water inlet paddle, the water inlet paddle has a limiting recess on a top of the water inlet paddle for receiving the bottom of the rotatable head, the bottom of the rotatable head is slidable leftward and rightward inside the limiting recess to tilt the left end and the right end of the water inlet paddle upward and downward, so as to cover one of the two water inlet columns by the water inlet paddle to control water to only enter into one of the two water inlet columns when the water flows into the water inlet mechanism;
• the control lever has a spring hole on a bottom of the control lever for receiving a top end of a spring, and a bottom end of the spring resists against the rotatable head to urge the rotatable head against the limiting recess of the water inlet paddle.
