Arrangement structure of handle seat, engine and transmission box of a portable tillage machine

Abstract

The invention discloses a portable mini-tiller handle base, engine and transmission case arrangement structure. A transverse beam (2) is fixed with the upper end of a front bracket (16); the left and right ends of the bottom of the front bracket (16) are connected with the top of the front end of a screw rod transmission case (15) through bolts; a supporting plate (3) is arranged on the middle part between two horizontal segments of a main tube (1); the end part of the supporting plate (3) is fixed with the tube body of a corresponding horizontal segment of the main tube by welding; an engine (17) is supported on the supporting plate (3); an output shaft of the engine (17) horizontally extends backwards; the bottom of the engine (17) is fixed with the supporting plate (3) through four bolts which are distributed in a rectangular form. The handle base and a handle tube constructing a handle are separated from each other, so that convenience is brought to disassembly and assembly, and the packaging and transportation costs can be effectively reduced; the engine and the screw rod transmission case are arranged horizontally, so that the size of a mini-tiller can be further reduced, and the mini-tiller is arranged firmly and reliably and has high stability.

Description

technical field [0001] The invention belongs to the technical field of tillage machines, and in particular relates to the arrangement structure of a handle seat, an engine and a transmission box on a 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, ...

AI Technical Summary

Problems solved by technology

The existing micro-tiller frame not only has complex structure, difficult processing and high production cost, but also takes up a lot of space, which will increase the volume of the entire micro-tiller, which is not conducive to the development of micro-tillers in the direction of miniaturization

[0004] The handle on the tiller is generally composed of a handle tube and a handle seat, and the handle tube and the handle seat are usually in one structure, so that the space is large and will increase the cost of packaging and transportation; at the same time, the handle seat is connected on the frame The reliability is poor, and the disassembly operation is inconvenient

[0005] The powertrain on the tiller usually uses 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 other hand, the vertical engine is on the frame. It takes up a lot of space and will increase the volume of the whole tiller

[0006] Corresponding to the engine, the screw transmission box is also installed vertically, so the installation process of the worm transmission box is more complicated and the reliability is poor; the worm transmission box takes up a lot of space on the frame, and it will also increase the volume of the whole tiller
