Abstract
A reinforcement crank relates to the technical field of agricultural machinery. The rocker arm is characterized in that a grooved wheel (3) is fixedly connected to the rocker arm (2), a notch (4) is formed in one side of the grooved wheel (3), and a reinforcing rib (5) is arranged on the grooved wheel (3). A bearing (6) is arranged between the swinging head (7) and the grooved wheel (3). Because the grooved wheel is arranged, the pull rope can be wound on the grooved wheel, and the grooved wheel and a person shaking the rocking handle are simultaneously stressed, so that the machine can be started more easily. In addition, a bearing is added at the supporting point, so that sliding friction is changed into rolling friction, and the friction force is reduced.
Description
The utility model relates to the agricultural machinery technology field.
Traditional crank that agricultural tricycle or four-wheel tractor are used can only be shaken by a people.It is very difficult that the people that strength is little shakes machine.The shake the head strong point of rear portion and machine of the long crank that particularly has is a sliding friction, shakes more difficult.
The purpose of this utility model provides and a kind ofly can apply external force by other people and help the crank people to shake, and reduces the Energizing crank of strong point place friction simultaneously.
For reaching above-mentioned purpose, take following technical scheme: the utility model includes rocking handle 1, rocking arm 2, shakes the head 7, fixedly is connected to sheave 3 on the rocking arm 2, and sheave 3 one sides are jagged 4, and sheave 3 is provided with reinforcement 5.
In addition, shake the head 7 and sheave 3 between be provided with bearing 6.
Owing to be provided with sheave, can on sheave, twine stay cord, afterburning simultaneously with the people of hand rocking handle, start machine with comparalive ease.Add upper bearing (metal) at strong point place in addition, the change sliding friction is rolling friction, has reduced friction.
Below in conjunction with drawings and Examples the utility model is elaborated.
Fig. 1 is the utility model front view,
Fig. 2 is the utility model side view.
Sheave 3 usefulness round steel are processed.Bearing 6 is used standard component.Sheave 3, bearing 5 and traditional crank welded together just can be made into the utility model.During use, rope is entangled in sheave 3 grooves, can more easily starts machine with crank people reinforcing.
Claims (2)
1, a kind of Energizing crank includes rocking handle (1), rocking arm (2), shake the head (7), it is characterized in that: rocking arm (2) is gone up and fixedly is connected to sheave (3), sheave (3) one sides jagged (4), and sheave (3) is provided with reinforcement (5).
2, Energizing crank according to claim 1 is characterized in that: be provided with bearing (6) between (7) and the sheave (3) shaking the head.
