To achieve these goals, the rotary gearshift of the microtilling machine that the utility model is designed, it comprises main transformer speed handle, place the gear level under the main transformer speed handle and be socketed in driving lever assembly on the gear level, after rotating, main transformer speed handle drives the motion of driving lever assembly, thereby realize gearshift, it is characterized in that between described gear level and the driving lever assembly being the linkage structure of tooth and teeth groove.
Described driving lever assembly comprises the coupling shaft that is socketed on the gear level, is provided with the driving lever mounting plate that is fixedly connected with it outside coupling shaft, has the connecting plate that is socketed with gear level at the driving lever mounting plate.
In order to make the driving lever assembly cooperate rotation with gear level, be provided with tooth in the described coupling shaft, be provided with the teeth groove that matches with tooth at gear level.
In order to make the driving lever assembly cooperate rotation with gear level, described gear level is provided with double wedge, is provided with the teeth groove that matches with double wedge at coupling shaft.
For with the gear level return and be convenient to pull out gear level, be provided with the with it return spring of socket at gear level, described return spring places the below of connecting plate.
For fixing return spring, do not allow return spring come off, be provided with the packing ring that is socketed on the gear level in the return spring lower end, have bolt for retaining washer at packing ring.
In order to increase the crush resistance of connecting plate and driving lever mounting plate, have vertical shaft at coupling shaft, be provided with connecting sleeve at the vertical shaft two ends, between connecting sleeve and coupling shaft, be provided with plain washer.
The rotary gearshift of the microtilling machine that the utility model obtains is made as the tooth linkage structure with the joint of gear level and driving lever assembly, so that main transformer speed handle can be thrown off the fixing of spline under the extruding of return spring, thereby realize the purpose of the light Rotate 180 of main transformer speed handle °, not only simple in structure, and easy to operate.
Description of drawings
Fig. 1 is the generalized section of gearshift among the embodiment;
Fig. 2 is the fractionation schematic representation of Fig. 1.
Among the figure: main transformer speed handle 1, gear level 2, coupling shaft 31, driving lever mounting plate 32, connecting plate 33, driving lever 34, return spring 4, vertical shaft 5, connecting sleeve 6, plain washer 7, packing ring 8, bolt 9, wear washer 10.
Embodiment
Below in conjunction with drawings and Examples the utility model is further specified.
Embodiment 1:
The rotary gearshift of the microtilling machine that present embodiment provides, as shown in Figure 1 and Figure 2, it comprises main transformer speed handle 1, place the gear level 2 under the main transformer speed handle 1 and be socketed in driving lever assembly on the gear level 2, described gear level 2 upper ends are provided with the teeth groove on the vertical direction, and gear level 2 is connected mutually welding with main transformer speed handle 1; Described driving lever assembly comprises the coupling shaft 31 that is socketed on the gear level 2, described coupling shaft 31 is provided with the tooth that matches with teeth groove, outside coupling shaft 31, be provided with the with it driving lever mounting plate 32 of welding, be provided with driving lever 34 in driving lever mounting plate 32 upper-end surfaces, be provided with connecting plate 33 in driving lever mounting plate 32 lower end surfaces, the end of described connecting plate 33 is enclosed within on the gear level 2; Be provided with the return spring 4 that is socketed in outside the gear level 2 below connecting plate 33, be provided with packing ring 8 at the end of gear level 2, described packing ring 8 external diameters are greater than the external diameter of return spring 4, have bolt 9 for retaining washer 8 at packing ring 8.When needs are changed 180 ° with main transformer speed handle 1, be pulled upwardly main transformer speed handle 1, return spring 4 is squeezed and shortens, and the tooth on the coupling shaft 31 is thrown off the teeth groove on the gear level 2, and at this moment, main transformer speed handle 1 can arbitrarily rotate, and changes direction.
In order to increase the crush resistance of connecting plate 33 and driving lever mounting plate 32, have vertical shaft 5 at coupling shaft 31, be provided with connecting sleeve 6 at vertical shaft 5 two ends, between connecting sleeve 6 and coupling shaft 31, be provided with plain washer 7.
In order to increase the working life of coupling shaft 31 and gear level 2, be provided with the wear washer 10 that is socketed on the gear level 2 above the coupling shaft 31.
In the present embodiment, the tooth on the coupling shaft 31 is splined shaft.
In the present embodiment, also tooth can be arranged on the gear level 2, teeth groove is arranged on the driving lever assembly.
The embodiment of present embodiment is as described below, and as shown in Figure 1, main transformer speed handle 1 is fixedly connected with gear level 2, is provided with the return spring 4 that is enclosed within on the gear level 2 in driving lever assembly lower end.When needs were shifted gears, because gear level 2 is connected with coupling shaft 31 teeth in the driving lever assembly, as long as main transformer speed handle 1 is applied the power of a swing, main transformer speed handle 1 just can drive coupling shaft 31 rotations, thereby so that driving lever move thereupon, thereby realization is shifted gears.Behind the handrail that rotates microtilling machine, main transformer speed handle 1 upwards can be lifted, the tooth in gear level 2 and the driving lever assembly is thrown off, and when tooth broke away from teeth groove fully, namely rotatable main transformer speed handle 1 was realized the rotation of main transformer speed handle 1.Because under the driving lever assembly, gear level 2 is provided with return spring 4, and main transformer speed handle 1 and gear level 2 welding are so when upwards lifting main transformer speed handle 1, return spring 4 will be squeezed.After main transformer speed handle 1 is turned to suitable position, aim at coupling shaft 31 and put down, so that tooth matches with teeth groove.At this moment, under the pulling force of return spring 4, main transformer speed handle 1 and gear level 2 are got back to original position.
Need to prove at last, above embodiment is only in order to the technical solution of the utility model to be described but not the restriction technologies scheme, although the claimant has been described in detail the utility model with reference to preferred embodiment, those of ordinary skill in the art is to be understood that, those are made amendment to the technical solution of the utility model or are equal to replacement, and do not break away from aim and the scope of the technical program, all should be encompassed in the middle of the claim scope of the present utility model.
