Two-gear micro ploughing machine

Abstract

The invention discloses a two-gear micro ploughing machine. An engine (1) is mounted at the front end of the top of a main transmission case (5), a handhold assembly (2) is mounted at the rear end of the top of the main transmission case (5), an output shaft of the engine (1) extends into the main transmission case (5) and is connected with a driving wheel shaft (5a), the lower end of a driven wheel shaft (5f) is connected with the input end of a worm transmission case (6), and a ploughing knife (7) or a travelling wheel is mounted on an output shaft of the worm transmission case (6); a positioning frame (10) is arranged in front of the worm transmission case (6) and consists of a top plate and side plates symmetrically arranged left and right, the upper end of a sloped tube (9) is positioned between the two side plates of the positioning frame (10), and a front wheel (8) is mounted under the sloped tube (9). The micro ploughing machine disclosed by the invention is simple and compact in structure, small in size and low in cost; the front wheel has two states of folding and unfolding, so that the requirements for different using states of the micro ploughing machine can be met. The micro ploughing machine has two gears of high speed and low speed, and is smooth and reliable in transmission, and the applicable range is wide.

Description

technical field [0001] The invention belongs to the technical field of agricultural machinery, and in particular relates to a two-speed 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 the majority of farmers to replace cattle plowing. [0003] At present, all the functional components on the tiller are arranged around the frame, which is not only c...

AI Technical Summary

Problems solved by technology

[0003] At present, all functional components on the micro tillage machine are arranged around the frame, which not only has complex structure, difficult assembly, high production cost, but also the large size of the whole machine, which is not conducive to the development of miniaturization

In addition, when the micro-tiller replaces the tiller with a walking wheel, it is only supported by two walking wheels and the ground. When the operator holds the handrail to push the micro-tiller, he has to press down or lift the handrail. To maintain the balance of the whole machine, the operation is very laborious
