Embodiment Construction

[0016] The present invention will be further described below in conjunction with the embodiments and accompanying drawings.

[0017] Such as Figure 1-3 As shown, a gear shift mechanism of a micro tillage machine includes a main shaft and a secondary shaft, the main shaft includes a first main shaft 1 and a second main shaft 2 arranged on the same straight line, any end of the first main shaft 1 is connected to the Either end of the second main shaft 2 is looped, that is, an inner cavity 15 is provided at the end of the first main shaft 1 close to the second main shaft 2, and the end of the second main shaft 2 close to the first main shaft 1 Extending into the inner cavity 15, the protruding end of the second main shaft 2 is connected with the wall of the inner cavity 15 through the first needle bearing 16, and the input gear 5 is set on the first main shaft 1. The input gear 5 is connected to the first main shaft 1 by a spline, so that the input gear 5 can slide axially alon...

Abstract

The invention discloses a mini-tiller transmission gear shifting mechanism. The mini-tiller transmission gear shifting mechanism comprises a main shaft and a secondary shaft arranged in parallel, wherein the main shaft includes a first main shaft and a second main shaft arranged on the same straight line; the first main shaft is coated with an input gear; the second main shaft is fixedly coated with a first main gear, and is coated with a main shaft duplex gear; the secondary shaft includes a first secondary shaft and a second secondary shaft; the first secondary shaft, the second secondary shaft and the main shaft are in parallel; the first secondary shaft is movably coated with a secondary shaft duplex gear, and is fixedly coated with a quick-gear driven gear and a slow-gear driven gear; the second secondary shaft is movably coated with a reverse-gear gear; the change of high and low input speed is realized through a first poking fork mechanism controlling sliding of the input gear; a second poking fork mechanism controls sliding of the main shaft duplex gear; and a third poking fork mechanism controls sliding of the reverse-gear gear to realize the reverse gear switchover. The structure provides an advance gear with four different speeds and a reverse gear with two different speeds, is suitable for various cultivation conditions, and satisfies the demands of actual production.

Description

technical field [0001] The invention belongs to the technical field of agricultural machinery, and in particular relates to a gear shift mechanism of a tiller gearbox. Background technique [0002] 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 equipment, it can be used for 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. [0003] The engine and the gearbox of the traditional tiller are only directly connected thr...
