Detailed Description

The utility model provides a pedal drive arrangement of kayak, includes the drive arrangement shell body that last casing 4, well casing 5 and casing 6 are constituteed down, last casing 4 in install big synchronous pulley 9 through first pivot 11, install little synchronous pulley 8 through second pivot 10 in the casing 6 down, the outside cover of big synchronous pulley 9 and little synchronous pulley 8 is equipped with hold-in range 12, the outside of casing 4 is all stretched out at the both ends of first pivot 11, the both ends of first pivot 11 all are fixed with running-board 13, the outside of casing 6 is stretched out down to the one end of second pivot 10, should stretch out to serve and be fixed with screw 14.

The utility model discloses install on the kayak, stretch into the aquatic with screw 14 of lower part, in the driven time, both feet are with strength pedal 13, because trample the bicycle generally. The pedal 13 drives the first rotating shaft 11 to rotate, the first rotating shaft 11 drives the large synchronous belt pulley 9 to rotate, the large synchronous belt pulley 9 drives the small synchronous belt pulley 8 to rotate through the synchronous belt 12, the small synchronous belt pulley 8 drives the second rotating shaft 10 to rotate, and the second rotating shaft 10 drives the propeller 14 to rotate, so that driving is achieved.

The transmission ratio between the large synchronous pulley 9 and the small synchronous pulley 8 is set as follows: the large synchronous pulley 9 rotates 1 turn, and the small synchronous pulley 8 rotates 9 turns.

The diameter of the first rotating shaft 11 is 16 mm, and the diameter of the second rotating shaft 10 is 9 mm.

An upper shell cover plate 3 is fixed on one side of the upper shell 4, and a lower shell cover plate 7 is fixed on one side of the lower shell 6.

The middle position of the middle shell 5 is fixed with a water baffle 15, the water baffle 15 is positioned right above the propeller 14, and the water baffle 15 effectively prevents the propeller 14 from splashing water onto the canoe.

Go up casing 4 on rotate and be connected with runing rest 2, runing rest 2 is kept away from the one end of last casing 4 and is fixed with horizontal pole 1, horizontal pole 1 is fixed in the fixed orifices on runing rest 2 by the centre gripping, runing rest 2 centre gripping is fixed on the position in the middle of horizontal pole 1. The rotating support 2 is convenient to fold after rotating, and does not occupy space when not in use, and when in use, two feet can be treaded on the cross rod 1 for rest.

The lower shell 6 is integrally provided with a balance wing plate 6-1 extending downwards, so that the balance of the kayak is kept.

The upper shell 4 and the middle shell 5 are fixedly connected through bolts, and the middle shell 5 and the lower shell 6 are fixedly connected through bolts.

Two sides of the lower part of the water baffle 15 extend downwards to form a side water baffle 15-1, so that the water baffle effect is better.
