Description
Technical field
The utility model belongs to the farm machinery technical field, relates to a kind of mini-size tillage machine, particularly a kind of Mini-tiller power driving control device.
Background technology
At Chinese countryside, the application of mini-size tillage machine is more and more extensive, is ploughing, is bringing into play increasing effect in arable land, farming.Mini-size tillage machine easily occurs in actual applications because controlling the incorrect accident of bleeding that causes, the incorrect main manifestations of above-mentioned control is that engine turns that the control that stops is unreasonable makes the rotor axle that engine shaft with it connects can not be with people's will running, turn round on the contrary such as may need it to stop the time, occuring under emergency situations, potential safety hazard to occur very easily.Traditional engine control has clutch lever to control and two kinds of Throttle Opening Control, be connected connection with rotating shaft to control the clutch connecting engine when controlling with clutch lever, but still can continue running in machine disengaging people's control situation when installing with this, so just be easy to occur security incident.With accelerator control device, acceleration cable is set on handle mainly, realize acceleration, idling and the parking of mini-size tillage machine by adjusting oil mass, but in this kind structure, regulating handle is not well located, when other controlling organizations by mini-size tillage machine such as shutdown handle control to mini-size tillage machine states such as realizing idling, because regulating handle does not obtain spacing preferably, will jump directly to dead ship condition, thereby make mini-size tillage machine stop, so there are the not enough problems such as poor controllability, poor safety performance in mini-size tillage machine.
Summary of the invention
The purpose of this utility model is for the above-mentioned existing state of the art, and provide a kind ofly control proper simple and safe Mini-tiller power driving control device.
The purpose of this utility model can realize by following technical proposal:
a kind of Mini-tiller power driving control device, be arranged in the transmission case between engine shaft and forerunner's axle, it is characterized in that, described Mini-tiller power driving control device comprises controller, transmission mechanism and tensioning apparatus, transmission mechanism includes a driving belt, belt is connected between the driven pulley that arranges on the driving wheel that arranges under engine shaft and forerunner's axle, tensioning apparatus includes regulating wheel and the hinge plate that resets, the hinge that resets plate is hinged in transmission case, one of the hinge plate that resets in transmission case connects regulating wheel, transmission case is stretched out in the other end, the hinge that resets plate case outside one pass through a bracing wire and be connected with controller, use controller can pull the bracing wire drive to reset and cut with scissors the rotation of plate.
Described belt is in relaxed state when not operating, regulating wheel can be realized tensioning and the purpose that relaxes to belt with the position relationship of the hinge plate that resets.
In above-mentioned Mini-tiller power driving control device, described controller comprises handrail and spring-grip, and spring-grip is connected with spring with handrail, and spring-grip can be in some rotation of handrail, and bracing wire is connected on spring-grip.The spring of above-mentioned spring-grip has reset response, and when it is let go, spring-grip resets, and stops the axis' control to the forerunner.
In above-mentioned Mini-tiller power driving control device, described hinge plate one end that resets is connected with back-moving spring, and the other end of back-moving spring is fixed on transmission case.The above-mentioned hinge plate that resets is by pulling bracing wire to make hinging rotary drive regulating wheel near belt, and spring at this moment is among elastic deformation, and spring reset makes regulating wheel away from belt after the bracing wire of hinge plate afterbody is lax.
In above-mentioned Mini-tiller power driving control device, described belt is connected between engine driving wheel and forerunner's axle driven pulley with lax state.Above-mentioned belt carries out degree of tightness by regulating wheel to it to be regulated, forerunner's axle motion during belt tension, and during belt slack, forerunner's axle loses driving force.
In above-mentioned Mini-tiller power driving control device, described forerunner's axle driven pulley bottom connection worm and gear.Worm and gear can be realized the break-in transmission, drives roller or cultivated cutter under it.
compared with prior art, the utility model is controlled forerunner's running in the instant mode of controlling of pressure, hand motion is synchronizeed with rotating shaft, because this mechanism forerunner's axle after unclamping spring-grip loses driving force immediately, the forerunner is decommissioned, so strong instant protective effect under emergency case, avoided having little time to stop controlling when finding dangerous situation as traditional mini-size tillage machine control system and produced the situation of tragedy, not need to restart engine at middle start-stop be will decrease in oil consumption to this device simultaneously, special picture is in northerly winter, outdoor temperature is very low, therefore mini-size tillage machine is difficult to igniting outdoor after restarting, this device has just solved these problems.
Description of drawings
Fig. 1 is Mini-tiller power driving control device structural representation.
Fig. 2 is Mini-tiller power driving control device vertical view.
In figure, 1, back-moving spring; 2, the hinge plate that resets; 3, regulating wheel; 4, forerunner's axle driven pulley; 5, handrail; 6, spring-grip; 7, bracing wire; 8, worm screw; 9, worm gear; 10, belt; 11, transmission case; 12, engine driving wheel.
Embodiment
As shown in Figure 1, the Mini-tiller power driving control device is arranged between engine driving wheel 12 and forerunner's axle driven pulley 4, comprise control handle, transmission mechanism and tensioning apparatus, its middle controller is comprised of handrail 5 and spring-grip 6, spring-grip 6 is connected with spring with handrail 5, spring-grip 6 can be in some rotation of handle, and bracing wire 7 is connected on spring-grip 6.The belt 10 that transmission mechanism includes a relaxed state is connected between engine driving wheel 12 and forerunner's axle driven pulley 4.Tensioning apparatus includes regulating wheel 3, reset hinge plate 2 and a back-moving spring 1, the hinge that resets plate 2 is hinged with transmission case 11,2 one of the hinge plates that reset in transmission case 11 connect regulating wheel 3, transmission case 11 is stretched out in the other end, the hinge that resets plate 2 stretches out a connecting stay wire 7 of transmission case 11, and the position relationship of regulating wheel 3 can be regulated the degree of tightness state of belt 10.Forerunner's axle driven pulley 4 lower ends are connected with worm and gear, and worm and gear can be realized the break-in transmission, drive roller or cultivated cutter under it.
Can see in the vertical view of Fig. 2, when the needs machine is worked, at first the running that keeps engine, then hand is firmly held spring-grip 6, the bracing wire 7 that is connected with spring-grip 6 will be drawn one and is applied on hinge plate 2 one ends that reset that stretch out transmission case 11, again because the hinge plate 2 that resets is articulated and connected with transmission case 11, therefore can rotate around a bit, drive anterior regulating wheel 3 and rely on belt 10, this moment, belt 10 will drive the rotation of forerunner's wheel under the state of tensioning, and the worm and gear that drives under forerunner's wheel also synchronously rotates thereupon.When occuring, emergency situations unclamps immediately spring-grip 6, by the built-in spring reset of spring-grip 6, the hinge that resets plate 2 has also just lost pulling force, reset by back-moving spring 1, regulating wheel 3 leaves belt 10 naturally, belt 10 becomes again relaxed state disappears the driving force that the forerunner takes turns, and reaches the purpose that immediately stops.
