Problems solved by technology

[0006] Yet adopt the hand crank starter of the diesel engine in the above-mentioned patent, still there is following defect: 1. the service life is short, through inventor's test, adopt above-mentioned hand crank starter, after using tens times to about a hundred times, the starter will fail and be completely unusable
2. The cost is high. With the above-mentioned manual starter, the spring needs to be replaced after dozens of times of use, which increases the cost of use
3. The startup speed is slow, and it takes an average of 10s to start once

Embodiment 1

[0042] Embodiment 1: as Figure 1-3 As shown, a hand starter includes a rocker arm 1 and a rocker shaft 2 connected to the rocker arm 1, the rocker shaft 2 is connected to a speed-up mechanism 3, and the speed-up mechanism 3 is connected to a throwing block The mechanism 4 is connected, and the described block mechanism 4 drives the starting cup 5 of the engine.

[0043] Using the manual starter of this embodiment, the rocker arm 1 is manually shaken to make the rocker arm shaft 2 rotate, and the rocker arm shaft 2 drives the speed-up mechanism 3 to rotate and achieve the effect of speed-up through the speed-up mechanism 3, and then The speed-up mechanism 3 drives the block-throwing mechanism 4 to rotate, and the block-throwing mechanism 4 drives the starting cup 5 of the engine to rotate through the block. After the engine starts, the starting cup will continue to rotate and drive the block to rotate , at this time the manual shaking can be stopped, and the engine has been s...

Embodiment 2

[0046] Embodiment 2: as Figure 1-5 As shown, a hand starter includes a rocker arm 1 and a rocker shaft 2 connected to the rocker arm 1, the rocker shaft 2 is connected to a speed-up mechanism 3, and the speed-up mechanism 3 is connected to a throwing block The mechanism is connected with 4, and the described block throwing mechanism 4 drives the starting cup 5 of the engine.

[0047] Wherein, the speed-up mechanism 3 includes a planetary gear 31 , the rocker shaft 2 is connected with the planet carrier 32 of the planetary gear 31 , and the sun gear 33 of the planetary gear 31 is connected with the block throwing mechanism 4 . The block throwing mechanism 4 includes an outer casing 41 , and a block throwing part is arranged inside the outer casing 41 . The throwing block part includes a top wall 42 and a bottom wall 43 arranged in the outer casing 41, a support column 46 is arranged between the top wall 42 and the bottom wall 43, and the throwing block 44 is rotatably sleeved...

Embodiment 3

[0052] Embodiment 3: as Figure 1-5 As shown, this embodiment is an improvement on the basis of Embodiment 2. In this embodiment, a frictional pre-tightening force mechanism 6 is also provided between the speed increasing mechanism 3 and the block throwing mechanism 4 .

[0053] Wherein, the speed-up mechanism 3 also includes a top case 34 and a bottom case 35 arranged on both sides of the planetary gear 31, the top case 34, the ring gear of the planetary gear 31 and the bottom case 35 are connected by screws. The bottom shell 35 is sleeved on the rocker shaft 2 through a bearing, and the top shell 34 is sleeved on the gear shaft. An accommodating cavity for accommodating the friction pre-tightening force mechanism 6 is provided on the end wall of the top shell 34 . In this embodiment, the accommodating cavity is set as follows: in the middle of the end of the top case 34, a convex portion extending along the gear shaft is provided, and the convex portion is connected to the ...

Abstract

The invention discloses a hand-operated starter. The hand-operated starter comprises a rocker arm (1) and a rockshaft (2) connected with the rocker arm (1). The hand-operated starter is characterized in that the rockshaft (2) is connected with a speed increasing mechanism (3), the speed increasing mechanism (3) is connected with a flail block mechanism (4); and the flail block mechanism (4) drives a starting cup (5) of an engine. By the hand-operated starter, high starting speed can be guaranteed, and the service life is long.

Description

[0001] Technical field: [0002] The invention relates to a hand starter, and also relates to a tiller with a hand starter. [0003] Background technique: [0004] Tillers are powered by small diesel engines or gasoline engines, and have the characteristics of light weight, small size, and simple structure. Tillers are widely used in dry land, paddy fields, orchards, etc. in plains, mountains, and hills. Equipped with corresponding accessories, it can carry out pumping, power generation, spraying, spraying and other operations, and can also be towed for short-distance transportation. The tiller can be used freely in the field, which is convenient for users to use and store, eliminating the need for large-scale agricultural machinery to enter The troubles of mountainous fields are the best choice for farmers and consumers to replace cattle plowing. [0005] There are two ways to start the micro tillage machine at present. One is to start by hand. The pull plate is started by h...
