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 and 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 clutch labor-saving operating mechanism of a walk-behind cultivator, which comprises a clutch fork transmission arm, a clutch cable, a clutch tension spring, a pulley and an adjustment mechanism. The improvement is that a pulley is installed on the clutch fork transmission arm, the clutch cable is installed on the pulley, the clutch fork transmission arm is connected through the pulley, and the end of the clutch cable bypasses the pulley and is fixedly connected to the gearbox case. In addition, an adjustment mechanism is designed between the clutch fork transmission arm and the clutch fork shaft for connection. The operating mechanism utilizes the principle that the moving pulley saves half the effort to reduce the operating force of the operator's hand, thereby achieving the purpose of labor saving, thereby reducing the labor intensity of the operator and improving the service life of the clutch cable. At the same time, the structure is optimized by adopting the adjustment mechanism, the clutch cable holder, the wire tube holder, etc., so that the device has the advantages of simple structure, convenient installation and adjustment, 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...
