Abstract
A mini-tiller starter is suitable for starting a diesel engine of the mini-tiller, and can also be used for starting other diesel engines. The starter consists of three parts of an energy storage mechanism, an energy storage control mechanism and a one-way clutch, and is characterized in that the energy storage control mechanism is arranged on the tail end of a transmission system, i.e. behind a driven disk of the one-way clutch. When energy is stored, the elastic force of a volute spiral spring eliminates a gap between the parts of the whole transmission system, and impact cannot be generated at the moment when the energy is released. The starter is not only labor-saving to operate, but also is low in noise, and has high reliability and a long service life.
Description
Technical field
The present invention is a kind of microtilling machine starter, is applicable to the usefulness of the diesel engine starting of microtilling machine, also can be used for the startup of other diesel engine.
Background technique
What microtilling machine more and more was widely used in the rural holding cultivates, broadcasts receipts.The greatest problem that existing microtilling machine exists is difficulty in starting.The microtilling machine starter that uses at present is stay cord starter, needs enough power just can draw startup, not only operation effort, and boot disk and stay cord also damage easily.
Chinese patent 201110366029.8 discloses " a kind of air-cooled diesel engine starter ", and the unidirectional lock dog of this starter is provided in a side of the front end of transmission system, and namely before clutch driving plate, the lock object of unidirectional lock dog is whirlpool spring gear.During energy storage, clutch driving plate, clutch driven disc all are in free state, have the gap between clutch driving plate and the driven disc, the existence in these gaps, make energy discharge the strong impact of moment generation, damage easily parts, have the shortcoming that rate of fault is high, working life is short.
Summary of the invention
The purpose of this invention is to provide a kind of microtilling machine starter, this starter is the time marquis of energy storage, and the institute of just having eliminated between the transmission system part is gapped, when releasing energy, just do not have impact, not only rapid operation, and reliability is high, low, the long service life of noise.
Technological scheme of the present invention is as follows: the microtilling machine starter is comprised of stored energy mechanism, energy storage control mechanism and overrunning clutch three parts.Stored energy mechanism is comprised of starter housing (1), gearwheel (2) crank handle interface (3), small gear (4), connecting pin (5) and spiral spring (6) as shown in Figure 1 and Figure 2.The energy storage control mechanism is comprised of ratchet handle (8), ratchet (9) as shown in Figure 3, Figure 4, and the other end of ratchet handle is ratchet.Overrunning clutch is comprised of clutch shaft (7), clutch driving plate (11), clutch driven disc (10).It is characterized in that: the energy storage control mechanism is located at the end of transmission system, namely after the driven disc of overrunning clutch.This routine ratchet (9) becomes as a whole with clutch driven disc (10), and is rigidly connected with engine flywheel, and locking ratchet (9) has just locked engine flywheel, also ratchet directly can be designed on the flywheel of motor.And the energy storage control mechanism is not located at before the driving disc of overrunning clutch, that is to say to carry out energy storage by the driving components such as driving disc of locking small gear, gearwheel or overrunning clutch.
During energy storage, the ratchet of ratchet handle (8) is placed the position of locking ratchet (9), shown in the handle position of Fig. 3.The inner of spiral spring is connected with clutch shaft (7), locked by the energy storage control mechanism by overrunning clutch, the inner of spiral spring can not be rotated, connect crank handle rocking-turn small gear (4), driving gearwheel (2) rotates, the outer end of spiral spring (6) namely by connecting pin along with gearwheel rotates, rotate the spiral spring outer end, spring turns tighter and tighter, storage elasticity potential energy, the elastic force of spiral spring runs through whole transmission system, until blocked clutch driven disc (10), this has just eliminated the gap between whole transmission system part.When releasing energy, pull ratchet handle (8), ratchet (9) loses locking, the spring drive engine rotation that releases energy.Because the institute of having eliminated between the transmission system part is gapped, the moment that releases energy just can not produce impact, has realized purpose of the present invention.

Embodiment
As shown in Figure 1, the microtilling machine starter is comprised of stored energy mechanism, energy storage control mechanism and overrunning clutch three parts.Stored energy mechanism is comprised of starter housing (1), gearwheel (2), crank handle interface (3), small gear (4), connecting pin (5), spiral spring (6) again.Small gear (4) axle head is provided with a crank handle interface (3), small gear and gearwheel engagement, gearwheel (2) is provided with connecting pin (5), connecting pin (5) is connected with the outer end of spiral spring (6), gearwheel drives the outer end of spiral spring and rotates when rotating, the inner of spiral spring (6) is connected with clutch shaft (7).
The energy storage control mechanism, it is exactly a ratchet and pawl arrangement, consisted of by the pawl-and-gearing (9) with handle, pull ratchet handle (8) during energy storage as shown in Figure 3, ratchet locking ratchet is pulled ratchet handle (8) as shown in Figure 4 when releasing energy, ratchet is decontroled ratchet, ratchet can rotate, and ratchet and clutch driven disc are as a whole, and is rigidly connected with engine flywheel.
Overrunning clutch comprises that clutch shaft (7), clutch driving plate (11), clutch driven disc (10) form, clutch shaft (7) and clutch driving plate (11) are as a whole, can only the one direction transferring power between clutch driving plate (11) and the clutch driven disc (10), be that driving disc can drive the driven disc rotation, driven disc can not drive driving disc and rotate, after guaranteeing engine start, do not interfere between the motor of running and the starter that stops.
During energy storage, at first pulling ratchet handle (8) makes ratchet place locked position, as shown in Figure 3, locking ratchet (9) has just locked engine flywheel, then connect crank handle rocking-turn small gear (4), driving gearwheel (2) rotates, the connecting pin (5) that is fixed on the gearwheel rotates along with gearwheel, be connected with the outer end of spiral spring (6) on the connecting pin, the outer end of spiral spring (6) namely by connecting pin along with gearwheel rotates, the inner of spiral spring is connected with clutch shaft (7), clutch shaft (7) is locked by the energy storage control mechanism by overrunning clutch, the inner of spiral spring can not be rotated, but the elastic force of spiral spring but acts on clutch shaft (7), clutch driving plate (11), clutch driven disc (10), on the whole parts such as ratchet (9), running through whole transmission system, eliminated the gap between each part of transmission system, continue the rocking-turn crank handle, spring turns tighter and tighter, storage elasticity potential energy, when energy storage arrives enough ato units, pull ratchet handle (8), ratchet is placed leave the position of ratchet, handle position as shown in Figure 4, ratchet namely rotates, this moment, spiral spring released energy, drive motor and make engine start, owing to eliminated the gap between each part of transmission system, the moment that releases energy just can not produce impact, engine speed after the startup increases rapidly, because the effect of overrunning clutch, clutch driven disc (10) can not drive clutch driving plate (11), can not interfere between the motor that namely turns round and the starter that stops.
