Air-cooled diesel engine pull-free starter

Abstract

The invention relates to a pull-free starter for an air-cooled diesel engine. The pull-free starter comprises a shell, a spiral spring, a spiral spring fixing plate, a spiral spring box, a central shaft and an intermediate shaft. The intermediate shaft is a hollow shaft which passes through the bottom center of the shell. The head of the central shaft is abutted to the outer side of the shell. The intermediate shaft is sleeved on the central shaft. The intermediate shaft is provided with a shaft ring which is provided with through stopper grooves. A one-way stopper is hinged inside each stopper groove. The bottom of each stopper groove is provided with a spring hole. An ejector spring is disposed in each spring hole. The top end of each ejector spring is abutted to the bottom of the corresponding one-way stopper. A first driven gear is fixedly mounted between the head of the intermediate shaft and the shaft ring. A scroll shaft is rotatably connected to the segment between the shaft ring and the tail of the central shaft. The pull-free starter has the advantages that a starting jaw is manually adjusted to extend out before being fitted into a starting jaw disc of the diesel engine, action of pure manual control is soft, the problem of hard impact between the starting jaw and the diesel starting jaw disc is avoided, and the safety is absolute.

Description

technical field [0001] The invention relates to the technical field of diesel engine starting, in particular to an air-cooled diesel engine pull-free starter. Background technique [0002] With the development of the agricultural economy, the degree of agricultural mechanization has gradually increased, and agricultural tillage machines have become more and more popular. The power source is a diesel engine, which is an engine that burns diesel to obtain energy release. It has high power, high thermal efficiency, and good economic performance. Advantages, the diesel engine must use a set of starting mechanism before it can enter the running state. The existing diesel engine starting device has two kinds of manual starting and electric starting. It is also inconvenient, and the traditional manual starting mode is adopted, that is, the starting claw of the starter can be snapped into the claw plate of the diesel engine, and then the manual starter can drive the diesel engine to...

Problems solved by technology

[0003] The technical problem to be solved by the present invention is: in order to overcome the easy damage problem caused by the hard impact between the starting claw and the starting claw disk of the diesel engine in the prior art, and to send the starting claw into the diesel engine by rotating the handle for more than half a circle under the action of the scroll spring In order to solve the problem of personal injury in the hole of the starter claw plate, an air-cooled diesel engine starter with no safety hazards and long service life is provided. It manually rotates the intermediate shaft to make the starter claws stretch out in advance and smoothly snap into the starter of the diesel engine. In the claw plate, there is no hard contact between the starting claw and the starting claw plate during the whole process, it is a very soft contact, which solves the problem of hard impact very well
