Embodiment Construction

[0018] In order to make the technical means, features, goals and effects achieved by the present invention easy to understand, the present invention will be further described below in conjunction with specific illustrations.

[0019] see figure 1 with figure 2 , the illustrated walk-behind cultivator clutch labor-saving operating mechanism includes clutch shift fork transmission arm 1, clutch cable 16, clutch extension spring 7, pulley 15, adjustment mechanism and so on.

[0020] The clutch shift fork transmission arm 1 is designed as a flat L-shaped arm in order to meet the needs of the installation arrangement. Clutch shift fork transmission arm 1 left end is connected with the clutch shift fork shaft 13 that is installed on the gearbox casing 18, can rotate around clutch shift fork shaft 13. An adjustment mechanism is connected between the clutch fork transmission arm 1 and the clutch fork shaft 13, and the adjustment mechanism is composed of a pull rod 14, an adjustment...

Abstract

The invention relates to a clutching labor-saving operating mechanism of a hand-held type cultivator, comprising a clutch shift fork transmission arm, a clutch cable, a clutch tension spring, a pulley and a regulation mechanism. The clutching labor-saving operating mechanism of the hand-held type cultivator is improved in such a way that the clutch shift fork transmission arm is provided with the pulley; the clutch cable is arranged on the pulley and is connected with the clutch shift fork transmission arm through the pulley; the tail end of the clutch cable is fixedly connected with a box body of a gear-box round the pulley; and besides, the regulation mechanism is connected between the clutch shift fork transmission arm and a clutch shift fork shaft. The clutching labor-saving operating mechanism reduces the hand-holding operating force of an operator by utilizing a principle of a movable pulley saving half force, thereby achieving the purpose of saving labor, reducing the labor intensity of the operator and prolonging the service life of the clutch cable; in addition, the clutching labor-saving operating mechanism further has simple structure, convenient installation and regulation, and the like by optimizing the structure through the regulation mechanism, a clutch cable base, a conduit tube base, and the like.

Description

technical field [0001] The invention relates to a clutch opening and closing mechanism, in particular to a clutch opening and closing operating mechanism of an agricultural walk-behind cultivator. The clutch operating mechanism can keep the clutch in a normally open state, and the operation is labor-saving. Background technique [0002] At present, the walk-behind cultivator uses a normally closed clutch, which controls the connection and disconnection of the clutch as required by a set of clutch control mechanism, so that the cultivator works or stops working. [0003] Due to the use of a normally closed clutch, if the operator loses control of the machine due to an accidental trip during work, the machine cannot automatically stop working, so there is a potential safety hazard. In order to avoid the occurrence of the above situation, the prior art discloses a "hand-held working machine clutch control device" (CN100490624C), which can make the clutch in a normally open stat...
