Grass grasping machine with diaphragm spring clutch

Abstract

The invention discloses a grass grasping machine with a diaphragm spring clutch. A clutch is the diaphragm spring clutch, and comprises a clutch cover, a friction plate, a pressure plate, support rings, a diaphragm spring and a driving spring, wherein a clutch belt pulley is fixedly connected with the outer edge of the clutch cover; the friction plate is clamped between the end face of the clutch belt pulley and the pressure plate; the driving spring is connected to the outer peripheral surface of the pressure plate; the other end of the driving spring is connected with the clutch cover; the inner edge of the clutch cover is connected with the diaphragm spring through rivets; two support rings which are same are arranged between the two lateral surfaces of the diaphragm spring and the rivets; the outer periphery of the diaphragm spring contacts with the raised part of the lateral surface of the pressure plate; and the inner periphery of the diaphragm spring contacts with a separation bearing. According to the grass grasping machine, a riveting structure is adopted for a diaphragm of the diaphragm spring clutch of the grass grasping machine, and separation gaps between every two of a plurality of separation claws are the same, and are not required to be regulated respectively; and the clutch of the grass grasping machine functions as a pressure element and a separation lever, so that the clutch is uniform in pressure, stable and reliable in torque transmission, smooth in jointing and convenient to operate.

Description

technical field [0001] The invention belongs to the field of agricultural machinery, and in particular relates to a diaphragm spring clutch grass catcher. Background technique [0002] The applicant discloses a small-sized folding grass grabber in the patent application with application number 201120361020.3. The clutch of the grass grabber uses a helical spring clutch. There is a gap △ between the bearings, the pressure plate presses the driven plate under the action of the compression spring, the torque of the engine is transmitted to the driven plate through the flywheel, the clutch pulley and the pressure plate, and then transmitted from the driven plate to the transmission input shaft . When the clutch is disengaged, the clutch pedal needs to be stepped on, and after the gap surface is eliminated through the pull rod, the release shift fork, and the release sleeve, the outer end of the release lever pulls the pressure plate to move backward against the pressure of the ...

AI Technical Summary

Problems solved by technology

After this kind of clutch works for a period of time, the separation gap of the separation lever often changes differently, resulting in poor coupling of the clutch and damage to the clutch. When adjusting the gap, the clutch must be removed and the separation lever adjusted separately, which requires high technical requirements for the operator. High strength, inconvenient to adjust
