Problems solved by technology

[0002] In today's existing handle-type agricultural machinery, the clutch of the agricultural machinery is to pull the clutch handle to separate the power of the engine, and to release the clutch handle to engage the power of the engine. When the agricultural machinery and the operator encounter a sudden accident It is difficult to protect the personal safety of the operator, and such clutches are becoming less and less suitable for farmers; especially in the supervision program for tillage machines in agricultural machinery, it is required that "the clutch control handle should be of the up-and-off type to ensure reliable operation after the clutch handle is released." cut power"

Embodiment 1

[0026] Embodiment 1: refer to Figure 1 to Figure 9 As shown, a hand-off clutch includes a transmission power shaft, a pulley, a clutch seat, a separation pawl, a clutch device, a driving disc, and a clutch adjusting bolt, wherein the driving disc 2 of the clutch device is set to a concave shape, and the concave shape The inner spline 17 is set inside, and the driving disc 2 is uniformly provided with holes 18 to pass through the spring sleeve 8, and the spring sleeve 8 places the clutch pressure spring 10, and the clutch adjustment bolt 11 of the clutch device that stops when the hand is released passes through the main pressure plate 15, Clutch pressure spring 10 and driving disc 2, and adjust the gap between the main pressure plate 15 and clutch pressure spring 10 with nut II7. At the same time, the clutch pressure spring 10 presses the middle pressure plate 16 and the asbestos sheet 9 through the spring sleeve 8, so that the middle pressure plate 16 Friction is generated b...

Embodiment 2

[0027] Embodiment 2: The overall structure is the same as Embodiment 1, the difference is that the driving disc 2 and the clutch adjusting bolt 11 are further improved, refer to Figure 10 to Figure 13 As shown, specifically, the bolt 4 on the main pressure plate 15 is changed to be welded on the driving disc 2 to enhance the stability of rotation; the clutch adjusting bolt 11 is changed to a countersunk head bolt 19, through the main pressure plate 15 and the nut I3, Nut II 7 cooperates with countersunk head bolt 19 to press the gap between the main pressure plate 15 and countersunk head bolt 19 to adjust the gap between the main pressure plate 15 and the part outside the middle diameter of the clutch stage 10 inside and outside the middle diameter.

[0028] Working principle: install the hand-off clutch device on the transmission power shaft 6 of the agricultural machinery through the bearing 5, the pulley 1 is connected with the engine through the V-belt, start the engine, a...

Abstract

The invention relates to a clutch capable of immediately stopping after hand leaving. The clutch comprises a transmission power shaft, a belt pulley, a clutch seat, a clutch device, a driving disc and clutch adjusting bolts, and is characterized in that the driving disc of the clutch device is concave; besides, an internal spline is arranged in the concave part of the driving disc; holes are uniformly distributed in the driving disc; the driving disc penetrates through a spring sleeve; clutch compression springs are placed inside the spring sleeve; the clutch adjusting bolts penetrate through a main pressing plate, the clutch compression springs and the driving disc; a clearance between the main pressing plate and the clutch compression springs is adjusted through tightening and loosening a nut II; the clutch compression springs press middle pressing plates and asbestos sheets through the spring sleeve, so that friction is generated among the middle pressing plates, the asbestos sheets and the driving disc; and the asbestos sheets drive the middle pressing plates and the driving disc to transmit power onto the transmission power shaft. Compared with the prior art, the clutch has the advantage that the function of protecting agricultural machinery and personal safety of operators is achieved under the condition that original functions of a traditional clutch are not changed.

Description

technical field [0001] The invention belongs to agricultural machinery, in particular to a hand-off clutch that protects the operator's personal safety. Background technique [0002] In today's existing handle-type agricultural machinery, the clutch of the agricultural machinery is to pull the clutch handle to separate the power of the engine, and to release the clutch handle to engage the power of the engine. When the agricultural machinery and the operator encounter a sudden accident It is difficult to protect the personal safety of the operator, and such clutches are becoming less and less suitable for farmers; especially in the supervision program for tillage machines in agricultural machinery, it is required that "the clutch control handle should be of the up-and-off type to ensure reliable operation after the clutch handle is released." Power off." Contents of the invention [0003] The object of the present invention is to provide a hand-off clutch that cuts off th...
