Embodiment 1

[0037] refer to figure 1 figure 2 image 3 Figure 4 , the present invention comprises a casing 1 and a rotating shaft 2 rotatably connected to the center of the bottom surface of the casing, the rotating shaft 2 is a hollow shaft, and a mandrel 3 is fixedly arranged inside it;

[0038] A driven gear 4, a ratchet 5, a scroll spring fixing plate 6, a scroll spring 7 and a starting pawl seat 8 are sequentially installed on the rotating shaft 2;

[0039] The scroll spring fixing plate 6 is fixedly connected with the inner wall of the casing 1;

[0040]The driven gear 4 is meshed with a preload gear 9, and the center of the preload gear 9 is provided with a preload shaft 10. One end of the preload shaft 10 is supported on the scroll spring fixed plate 6, and the other end protrudes from the casing 1 as a preload end 101. , a block 11 is also set on the pretension shaft 10, such as Figure 9 As shown, the edge of the block 11 has a locking tooth 111 arranged perpendicular to ...

Embodiment 2

[0046] like Figure 5 Image 6 , embodiment 2 is a further improvement on the basis of embodiment 1, a protective shell 21 is covered above the starting end 151, as Figure 7 Figure 8 As shown, there is a starting hole 211 on the protective shell 21, the starting hole 211 is facing the top of the starting end 151, and a shielding piece 22 for blocking the starting hole 211 is hinged inside the protective shell 21, and the second pull wire is connected to the end of the shielding piece 22. 23. The other end of the second pull wire 23 passes through the protective case 21 and is connected to the gear shifter of the locomotive. This improvement mainly focuses on the restriction on the starting end 151, because the pretensioning end 101 is the process of tightening the scroll spring 7, and the starting end 151 is the process of releasing the elastic potential energy of the scroll spring 7, so as long as the starting end 151 Install a protective shell 21 additionally. When the ...

Embodiment 3

[0049] like Figure 10 As shown, two pin shafts 24 are fixedly installed on the end face of the ratchet 5, and the two pin shafts 24 are symmetrical to the center of the ratchet 5, and two circles symmetrical to the center of the driven gear 4 are arranged on the end face of the driven gear 4. Arc groove 41, two pin shafts 24 that ratchet 5 passes are embedded in corresponding arc groove 41, and the center angle of arc groove 41 is 80 °, and ratchet 5 is provided with torsion spring, can conveniently like this Pawl 5 returns under the effect of torsion spring.

Abstract

The invention discloses a safety starter for an air-cooled diesel engine. The safety starter comprises a shell and a rotating shaft rotationally connected to the bottom center of the shell, wherein the rotating shaft is a hollow shaft, and a mandrel is fixedly arranged in the hollow shaft; the rotating shaft is sequentially provided with a driven gear, a ratchet wheel, a volute spiral spring fixing plate, a volute spiral spring and a starting jaw seat; the driven gear is meshed with a pre-tightening gear; the center of the pre-tightening gear is provided with a pre-tightening shaft; one end of the pre-tightening shaft is supported on the volute spiral spring fixing plate, and the other end of the pre-tightening shaft extends out of the shell to serve as a pre-tightening end; a check block is sleeved on the pre-tightening shaft; the edge of the check block is provided with a clamping tooth which is perpendicular to the end face of the check block and used for locking the driven gear; the check block is provided with a stay wire fixing end; the end face of the volute spiral spring fixing plate, which is opposite to the bottom of the shell, is provided with a stay wire bayonet; a first stay wire is fixed at the stay wire fixing end; and the first stay wire passes through the stay wire bayonet, extends out of the shell and is connected with an engine shifter. By the safety starter, injury accidents are avoided when the diesel engine is started at a non-neutral position, the safety factor is improved, and the safety starter is simple in structure and low in cost.

Description

technical field [0001] The invention relates to the technical field of diesel engine starting, in particular to an air-cooled diesel engine safety 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 st...
