Abstract

The utility model discloses an automatic manipulation mechanism on gasoline engine. The device is aim at solving the problem that the throttle control and the parking of the throttle manipulation controlling mechanism of small gasoline engine are separated as two parts, which have few controlling functions and can not satisfy the demands of mechanical use. The main technical proposal of the utility model is that the utility model is added with a speed constraint combination, a constant speed controlling combination and a self locking handle combination on the basis of structure of the manipulation mechanism of prior small gasoline engine, therefore making the manipulation mechanism have the functions of speed limiting control, constant speed control and self locking and control of the throttle, etc. The utility model is mainly used on small gasoline engines of plant protection machinery, garden machinery and forest protection machinery. The utility model is compact in structure, convenient in parking and simple in operation, and the utility model is characterized in increasing the no-fault working time of the gasoline engine, decreasing the labor intensity of operators and reducing accidents.

Description

Automatic controller on a kind of petrol engine

Technical field: the utility model relates to the miniature gasoline engine technical field, especially the power control control mechanism on the miniature gasoline engine.

Background technique: present common miniature gasoline engine; particularly equipment for plant protection, graden machine, the gloomy anti-mechanically power control control mechanism of the miniature gasoline engine of usefulness; Throttle Opening Control and parking are two parts; loosely organized, be difficult for the convenient functions such as the in use desired speed limit of machinery, constant speed, self-locking that realize.The high speed rotating that petrol engine is unnecessary easily causes the petrol engine fault, as scuffing of cylinder bore, and increases oil consumption; Petrol engine does not have constant rotating speed, has increased operator's labor intensity; Throttle does not have from the lock control function, easily has an accident.

Summary of the invention: the technical problems to be solved in the utility model is that power control control mechanism Throttle Opening Control and parking on the miniature gasoline engine are two-part, the mechanical functions such as realization speed limit, constant speed, self-locking that are difficult in manipulating.

The technological scheme of the utility model technical solution problem is, based on existing petrol engine operating mechanism, comprise the handle that left maneuver box, right maneuver box are formed, be located at the shutdown switch combination on the handle, be provided with power control handle, throttle rope, long torsion spring in the handle, be provided with the speed limit combination on handle, the speed limit combination comprises spacing bearing pin, the rotation into and out of restriction power control handle of spacing bearing pin is with the maximum speed of control throttle; Be provided with constant speed control combination on handle, constant speed control combination comprises a locking bearing pin, and advancing or going out locking or unclamp the power control handle a fixed position of locking bearing pin realizes that the constant speed of petrol engine is rotated; On handle, establish from the shank of the key combination, comprise, be in the relative position of power control handle from shank of the key from shank of the key, be in the state that pins the power control handle from shank of the key under the petrol engine idling mode, open behind shank of the key, reserve revolution space for the throttle handlebar, can open the throttle; When unclamping the power control handle to idling mode, the self-locking handle return pins the power control handle.

The end of handle is located in speed limit combination, adopts the turn-knob structure, and spacing bearing pin is a screw, and the nut on it is fixed on the handle, by rotary screw control screw into and out of.

Constant speed control combination comprises the locking bearing pin, lock the axially vertical of bearing pin with the plane of rotation of power control handle, spring bolt is located in the pin-and-hole on the handle, the head of locking bearing pin is provided with flange, in order to pin the power control handle, lock that the locking spring of suit props up on pin-and-hole on the bearing pin, the spring bolt shaft rear end is established knob, and the other end of locking spring props up on knob.Press knob, the locking bearing pin overcomes spring force and gos deep into handle, and the flange of spring bolt shaft head blocks the power control handle, and pins the power control handle under the pressure of locking spring.Continue to press down knob, can throw off the power control handle, return.

Comprise that from the shank of the key combination from shank of the key and self-locking torsion spring, self-locking torsion spring one end is pressed on the handle housing, the other end is pressed on shank of the key, and is corresponding with the power control handle from shank of the key, is divided into the both sides of handle.

Function of the present utility model and operation:

1, Control for Speed Limitation is regulated the speed limit combination screw is stretched out or indentation, stretches out the angle of swing that can limit the power control handle, thereby has limited running up of petrol engine.Rotating speed can be according to the load request free adjustment of petrol engine.

2, constant speed control, when long-time operation, after opening the throttle, press knob, by knob the locking bearing pin is inserted, at this moment unclamp the power control handle, the power control handle circles round to little throttle direction under the effect of long button spring and throttle rope, and the insertion of locking bearing pin makes the power control handle be lockable (concrete rotating speed is decided on load request that petrol engine is joined) in petrol engine constant rotational speed scope

3, throttle self-locking and control must be pressed earlier from shank of the key before opening the throttle, if do not press locking handle earlier, throttle can't strengthen.When pressing, after shank of the key is rotated counterclockwise an angle along the self poisoning axle, reserved revolution space for the throttle handlebar from shank of the key; At this moment can arbitrarily open the throttle, reach the purpose of Throttle Opening Control.When unclamp the power control handle and during from shank of the key, at first the power control handle circles round to little throttle direction under the effect of long button spring and throttle rope, when the power control handle is run into the handle location, the stall of power control handle.At this moment turn clockwise from shank of the key positioning shaft along self under the effect of self-locking torsion spring, when running into the handle location from shank of the key, stop, at this moment just in time hindering the power control handle and rotate (this moment is generally under idling mode) from the position that shank of the key is gone into.Play the purpose of the self-locking and the control of throttle.

4, shutdown switch is assembled in the top of handle, only needs with thumb shutdown switch upwards one to be pushed away gently, just petrol engine is shut down.

The utility model is mainly used in equipment for plant protection, graden machine and the gloomy anti-place that mechanically miniature gasoline engine of usefulness, particularly plant are intensive and uses more convenient.Throttle Opening Control and shutdown switch fit together, compact structure; Can realize high speed limit, reduce unnecessary the running up of petrol engine, improve the time between failures of petrol engine; Constant speed control has alleviated operator's labor intensity; The self-locking of throttle and control have reduced the generation of accident, and it is convenient, simple to operate to stop.
