Abstract
The utility model discloses a kind of microtilling machine and control hand handle, comprise operator handle, described operator is provided with open end for hand-held handlebar rubber cover, described operator on be fixed with clutch hand handle, described operator is provided with the two panels spring sheet of clamping clutch hand handle middle part, described spring sheet is by sheet and a knee-piece combine always, reduce gradually to increase gradually again in the distance described in the direction towards operator handle between two panels spring sheet, and near operator, the amplitude that place reduces is greater than amplitude place reduced away from operator, stiffening rib is provided with between the described spring sheet back side and operator handle.The utility model is simple to operate, and control force is stablized, handling reliable, improve utilization efficiency and the working life of clutch.
Description
Technical field
The utility model relates to a kind of microtilling machine, particularly relates to a kind of control hand handle be applied on microtilling machine.
Background technique
At present, the control hand of the normally open clutch that existing microtilling machine uses controls hand waiting what adopt to be that holding and Double-acting synchronizer control hand are these two kinds of structures with reverse gear, holding Clutch Control hand handle is that operator grips for a long time, the friction plate of clutch is made to combine the object reaching power transmission, this Clutch Control hand is indefinite there is clutch contact force size, power transmission weak effect, accelerate the wearing and tearing of clutch, reduce the life-span of clutch, and the labor intensity of this Clutch Control hand handle is large, affects the manufacturing efficiency of agricultural machinery.
Double-acting synchronizer controls hand handle, although solve the problem that operator's labor intensity is large, but its operation is comparatively complicated, this clutch handle primarily of fixed bearing, clutch hand handle and lock dog are formed, during operation, to hold with a firm grip clutch hand handle, clutch friction plate is contacted, press lock dog integral cast handle again, such operator would not use excessive power to remove holding operation, but just must add a power again when clutch is separated, lock dog on clutch handle is flicked, free fixing, just can make clutch separately, so the use of this clutch just must carry out twice operation, add operator's volume burden, and in machinery uses, because mechanical vibration are large, sometimes locking block can automatically spring open and free fixing, therefore very unreliable in actual applications.
Model utility content
Because the above-mentioned defect of prior art, technical problem to be solved in the utility model is to provide one and is applied on microtilling machine and simple to operate, laborsaving, reliable Mini-tiller clutch controls hand handle.
For achieving the above object, the utility model provides a kind of microtilling machine and controls hand handle, comprise operator handle, described operator is provided with open end for hand-held handlebar rubber cover, described operator on be fixed with clutch hand handle, described operator is provided with the two panels spring sheet of clamping clutch hand handle middle part, reduce gradually to increase gradually again in the distance described in the direction towards operator handle between two panels spring sheet, and near operator, the amplitude that place reduces is greater than amplitude place reduced away from operator, stiffening rib is provided with between the described spring sheet back side and operator handle.
The beneficial effects of the utility model are: the utility model is simple to operate, and control force is stablized, handling reliable, improve utilization efficiency and the working life of clutch.
Accompanying drawing explanation
Fig. 1 is that a kind of microtilling machine of the utility model controls hand the structural representation of embodiment.
Fig. 2 is the structural representation of the utility model spring sheet.
In figure: 1, operator handle; 2, clutch hand handle; 3, knee-piece; 4, spring sheet; 5, stiffening rib, 6, directly sheet.
Embodiment
Below in conjunction with drawings and Examples, the utility model is described in further detail:
See Fig. 1 to Fig. 2, a kind of microtilling machine controls hand handle, comprise operator 1, described operator is provided with 1 open end for hand-held handlebar rubber cover, described operator is being fixed with clutch hand on 12, described operator is provided with clamping clutch hand the two panels spring sheet 4 of 2 in the middle part of 1, described spring sheet 4 is by sheet 6 and a knee-piece 3 combine always, towards operator, the distance between two panels spring sheet 4 described in the direction of 1 is being reduced to increase gradually more gradually, and the amplitude that 1 place reduces is greater than near operator the amplitude 1 place reduced away from operator, described spring sheet 4 back side and operator are provided with stiffening rib 5 between 1.
The utility model when in use process is as follows: owing to being provided with spring sheet 4, when clutch clutch hand 2 time, because spring sheet 4 is greater than near operator the amplitude that 1 place reduces the amplitude 1 place reduced away from operator, so clutch hand 2 by compressing into spring sheet 4 than being easier to, when clutch hand enters 2 clampings after between spring sheet 4, as shown in Figure 2, owing to the distance between two panels spring sheet 4 described in the direction of 1 being reduced to increase gradually more gradually towards operator, so clutch hand can be subject to one towards operator the component in 1 direction 2, now only needing operator to add a smaller power thereon with hand just can make it can not eject, when needs clutch hand ejects spring sheet 42 time, only need operator to let go, clutch hand will automatic spring 2.In order to spring sheet 4 can be in stressed state for a long time, so be provided with stiffening rib 5 on the straight sheet 6 of spring sheet 4, increase its intensity.
More than describe preferred embodiment of the present utility model in detail.Should be appreciated that those of ordinary skill in the art just can make many modifications and variations according to design of the present utility model without the need to creative work.Therefore, all technician in the art according to design of the present utility model on the basis of existing technology by the available technological scheme of logical analysis, reasoning, or a limited experiment, all should by the determined protection domain of claims.
