A small tiller

Abstract

The invention discloses a mini-tiller. Main tubes (1) are U-shaped, wherein the front ends of the main tubes (1) are upwards tilted to form bumpers (1a); a support plate (3) is arranged on the middle part between two horizontal sections of each main tube (1); an engine (20) is supported on the support plates (3); a driving wheel (21) is arranged on an output shaft of the engine (20) in a sleeving way, and is connected with a driven wheel (23) through a belt (22); the driven wheel (23) is arranged on an input shaft of a screw transmission case (18) in the sleeving way. According to the mini-tiller, handle brackets and handle tubes, which form handles, form a split structure, so that the mini-tiller is convenient to assemble and disassemble; rear wheels can be simply and rapidly retracted or landed according to needs, so that the working efficiency of the mini-tiller can be effectively improved; the engine and the screw transmission case are horizontally arranged, so that the size of the mini-tiller can be further reduced; moreover, the screw transmission case can be firmly and reliably arranged, and is high in stability.

Description

technical field [0001] The invention belongs to the technical field of tillage machines, and in particular relates to a portable small tillage machine. Background technique [0002] Micro tillage machine is an agricultural tool in the new era. It has the characteristics of light weight, small size and simple structure. It is widely used in dry land, paddy fields, orchards, etc. in plains, mountains, and hills. , spraying and other operations, it can also be towed by a trailer for short-distance transportation. The micro tillage machine has strong flexibility, can drive freely in the field, is convenient for users to use and store, saves the trouble of large agricultural machinery not being able to enter the mountainous fields, and saves farmers a lot of time in the busy season. [0003] The frame is an important part of the tiller, and it is the skeleton of the tiller, which is used to arrange the powertrain, blade, handle and other components. The existing tiller frame no...

AI Technical Summary

Problems solved by technology

The above structure is not only cumbersome to disassemble and assemble, the labor intensity of the staff is high, and it will greatly reduce the working efficiency of the tiller

[0006] The powertrain on the tiller consists of an engine and a screw transmission box. The engine is usually a vertical engine. On the one hand, there are few types of vertical engines, which is not convenient for the tiller to choose the appropriate power according to actual needs; On the one hand, the vertical engine takes up a lot of space on the frame, which will also increase the volume of the whole tiller

The screw transmission box corresponding to the engine is also installed vertically, so the installation process of the worm transmission box is more complicated, the reliability is poor, and it takes up a lot of space on the frame
