Problems solved by technology

By shifting the positions of the double spur gears on the main shaft and the reverse gear shaft, fast gear, slow gear and reverse gear can be realized. There are few gears, so the forward and reverse speeds of the tiller are relatively single, especially there is only one reverse gear. There are great limitations in actual farming and cannot meet the actual needs of production

Embodiment Construction

[0015] The present invention will be further described below in conjunction with the embodiments and accompanying drawings.

[0016] Such as Figure 1-3 As shown, a high-low speed shifting mechanism of a tiller includes a main shaft A and an auxiliary shaft 3 arranged in parallel, wherein the main shaft A includes a first main shaft 1 and a second main shaft 2 arranged on the same straight line, and the first main shaft 1 Either end of the second main shaft 2 is connected with a looper at any end of the second main shaft 2, that is, an inner cavity 11 is provided at the end of the first main shaft 1 close to the second main shaft 2, and the second main shaft 2 is close to the first main shaft 2. One end of a main shaft 1 protrudes into the inner cavity 11, and the protruding end of the second main shaft 2 is connected with the wall of the inner cavity 11 through a first needle bearing 12, and an input shaft is set on the first main shaft 1. Gear 4, the input gear 4 and the fi...

Abstract

The invention discloses a mini-tiller high-low-speed gearshift which comprises a main shaft and an auxiliary shaft arranged in parallel, wherein the main shaft comprises a first main shaft and a second main shaft which are arranged on the same straight line; an input gear is mounted on the first main shaft in a sleeving manner; a first main gear is fixedly mounted on the second main shaft in a sleeving manner; an auxiliary shaft duplicate gear is movably mounted on the auxiliary shaft in a sleeving manner; a shifting fork mechanism enables the input gear to slide on the first main shaft so as to realize conversion of high and low input speeds. With adoption of the structure which is novel, the situation that the main shaft provides high and low input speeds for a mini-tiller gearbox is realized to double the gears, in other words, the selectable output speed options are doubled; the mini-tiller high-low-speed gearshift is suitable for various farming production situations and environments and meets the practical demands of production.

Description

technical field [0001] The invention belongs to the technical field of agricultural machinery, and in particular relates to a high-low speed shift mechanism of a tiller. 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 t...
