Abstract

The invention relates to a water pumping device which has the technical scheme that a magneto fastening bolt is arranged on a left crank inside an engine; a groove is arranged at the position on a left crank box cover of the engine just facing the magneto fastening bolt; the bottom of the groove is provided with a through hole communicated with an inner cavity of the engine; the groove on the left crank box cover of the engine is fixed with an inner connecting plate, the outer side of which is provided with a water pump by an outer connecting plate; an input shaft of the water pump sequentially passes through a center hole of the outer connecting plate, a center hole of the inner connecting plate and the through hole on the left crank box cover of the engine and then extends into the engine, and is connected with the magneto fastening bolt; and the middle part of the input shaft of the water pump is supported on the outer connecting plate by a bearing. The device leads the water pump to be skillfully installed on the engine of a motorcycle, and utilizes the power of the engine to drive a water pump impeller in a neutral gear state of the motorcycle so as to realize the work of pumping water, thus bringing convenience for pumping water by farmers and greatly lightening the burden of the farmers.

Description

technical field [0001] The invention relates to a water pumping device, so that the engine of the motorcycle can drive the water pump to complete the water pumping work. Background technique [0002] In the vast rural market, farmers friends cannot do without water pumps for drinking, watering and other water. Commonly used water pumps are integrated into a whole by a general-purpose gasoline engine and a water pump, and the output shaft of the gasoline engine drives the rotation of the impeller of the water pump to realize the pumping work. Because the water pumps are bulky and heavy (each at least 100 jin), it is extremely inconvenient to transport them to the pumping site. Especially when pumping water in a field far away from home, it often takes two people to carry the pump to the designated location. At the same time, the cost of the water pump is relatively high, and the price of one unit exceeds 1,000 yuan, which is difficult for farmers to accept. [0003] Two-wh...
