Abstract
The utility model discloses a normally disengaged clutch of a micro-cultivator. A clutch body mainly comprises a pressure plate, a pressure plate spline, a center sleeve, a pushing plate and a clutch friction core; and the normally disengaged clutch is characterized in that a plurality of springs are arranged between the pressure plate and the center sleeve, wherein the springs are pressure springs under the pressure of the pressure plate and the center sleeve. For the normally disengaged clutch of the micro-cultivator, the clutch is in normally disengaged type and in separation state for a long term, and only when an operator tightly pinches a handle of the clutch, the clutch is in combination state, friction disks are combined under the pressure, and the springs are in stress state; phenomena such as no or not clear separation, excessive wear and shortened service life of the friction disks, and the like with the reason that the friction disks of an original normally closed clutch are stuck together are avoided; and when the operator operates in a field, emergency parking can be realized at any time according to needs, and only releasing (releasing the handle of the clutch) emergency parking is needed in exceptional circumstances, thus guaranteeing the safety of the operator when in operation, and having easy operation.
Description
Technical field
The utility model relates to a kind of appurtenances clutch of actuating unit, especially mini-size tillage machine normally open clutch.
Background technology
Mini-size tillage machine is mainly used in the farming of the splat of hilly country, because the soil landform variation of hilly country is big, mini-size tillage machine needs to adjust duty because of topographic change at any time, otherwise fortuitous event can occur when the farming operation, and this moment, the operator need be stopped in emergency.In the prior art, the clutch of mini-size tillage machine transmission device all is to adopt normally closed type, clutch all is in bonding state in working order the time, the hand that must swap out when wanting to stop when the farming operation is operated gear lever, have only a palm control the hand steered device of mini-size tillage machine, bring more inconvenience to the operator, had certain potential safety hazard, even can cause security incident.This kind normally closed type clutch is when not operation of mini-size tillage machine, and clutch friction plate and driven disc still are in the bonding state under the pressure effect for a long time, and clutch spring also is in stress and fatigue failure easily for a long time.Because the seasonality of agricultural tillage relation is also long during mini-size tillage machine is obsolete, under the long-term stopped status between the operating period not, friction plate and driven disc are bonded together; When reusing, usually occur dividing too busy to get away or separating unclean phenomenon, influence is normally used, the wearing and tearing that increased friction plate, the life-span of having reduced friction plate.
Summary of the invention
The utility model all is to adopt normally closed type at the clutch of prior art mini-size tillage machine; clutch all is in bonding state in working order the time; there is certain potential safety hazard during parking; and mini-size tillage machine the stopped status between the operating period is not long; friction plate is bonded together with driven disc and branch occurs and be unable to do without or separate unclean phenomenon; the wearing and tearing of friction plate have been increased; the deficiencies such as life-span of friction plate have been reduced; provide a kind of just to be in bonding state in working order the time; be in released state under stopped status for a long time, spring is in relaxed state; friction plate is in the mini-size tillage machine normally open clutch of the released state that does not stress.
The technical solution of the utility model: mini-size tillage machine normally open clutch, clutch body mainly comprise platen, platen spline, center, push-plate, clutch friction core; It is characterized in that: between platen and center, several springs are set, spring is a stage clip, is subjected to the pressure of platen and center.
Further feature is: several spring placement holes are set on platen, in each spring placement hole spring are set, the upper end of spring withstands on the center.
In the contact site of platen and center, be provided with the connection pin.
Platen is provided with cover plate.
Mini-size tillage machine normally open clutch of the present utility model has following characteristics:
1, clutch is open in usual, is in released state for a long time, and only after the operator clutched the clutch handle, clutch just was in bonding state, and just pressurized combination of friction plate, spring just are in stress; Avoided the friction plate of original normally closed type clutch to be bonded together and branch occurred be unableing to do without or separating clean, phenomenons such as friction disc wear is serious, the reduction of friction plate life-span.
2, the operator can be stopped in emergency when farm work as required at any time, one have unexpected situation only need give up (loosen the clutch handle) stop in emergency, making the operator is that safety has had a guarantee in operation, easily operation.
3, clutch of the present utility model has the function of the mini-size tillage machine emergency stop device of Ministry of Agriculture's requirement, has satisfied the needs of safety work.

Embodiment
In Fig. 1,2,3,4,5, mini-size tillage machine normally open clutch of the present utility model comprises clutch body 1, and clutch body 1 mainly comprises platen 2, platen spline 3, center 4, push-plate 5, clutch friction core 6; Clutch friction core 6 is made up of friction plate and the driven disc alternately arranged, be arranged between platen 2 and the center 4, push-plate 5 is arranged on the center 4, and push-plate 5 shakes hands to be connected with outside clutch, active force is acted on the center 4, center 4 is moved vertically; Above as prior art, be not further described at this.
Mini-size tillage machine normally open clutch of the present utility model, its improvement is: between platen 2 and center 4, several springs 7 are set, spring 7 is stage clips, what be subjected to is the pressure of platen 2 and center 4; When specifically being provided with, several spring placement holes 8 are set on platen 2, in each spring placement hole 8 spring 7 are set, the upper end of spring 7 withstands on the center 4, and center 4 is given 7 one pressure of spring.When specifically being provided with, choose the spring 7 of appropriate length and spring ratio, after platen 2, center 4, push-plate 5 fitted together with clutch friction core 6, what spring 7 was subjected to was the pressure of center 4.The material of push-plate 5 is a bearing steel, has reduced the frictional resistance of push-plate 5, has strengthened wearability and has performed service life.
In the contact site of platen 2 with center 4, be provided with connection pin 9, have spacing and guide effect; Platen 2 is provided with cover plate 10, will connect in pin 9 is sealed on, and prevents that it from coming off in long-term running up.
Operation principle of the present utility model, with the platen 2 of clutch body 1, platen spline 3, center 4, push-plate 5, clutch friction core 6, after spring 7 grades fitted together, spring 7 was subjected to the pressure of platen 2; This moment, clutch was a released state, and promptly the friction plate of clutch friction core 6 does not combine with driven disc, not transferring power.After the operator clutches the clutch handle, give 5 one active forces of push-plate through the clutch drag-line, push-plate 5 promotes platen 2 and moves to center 4, has shortened the distance between platen 2 and the center 4, make the friction plate of clutch friction core 6 combine transferring power with driven disc.And behind operator's loosen the clutch handle, the active force that push-plate 5 acts on the platen 2 disappears, and the elastic force of spring 7 promotes platen 2 and outwards moves (away from center 4), the friction plate of clutch friction core 6 is separated, no longer transferring power with driven disc.
Clutch of the present utility model does not change its external dimensions, does not especially change assembly relation and position dimension with miscellaneous part, can be directly installed on the former mini-size tillage machine, and convenient the use has stronger versatility.
