Portable mini tiller rear wheel assembly engine and screw transmission box arrangement structure

Abstract

The invention discloses a portable mini tiller rear wheel assembly engine and screw transmission box arrangement structure. A main pipe (1) is in the shape of a U with the front end closed and the rear end open. The front end of the main pipe (1) is warped upwards to form a bumper (1a). A beam (2) is arranged on the front portion between two horizontal sections of the main pipe (1), the beam (2) and the upper end of a front support (16) are fixed, the left end and the right end of the bottom of the front support (16) are connected with the top of the front end of a screw transmission box (15) through bolts, a support plate (3) is arranged in the middle between the two horizontal sections of the main pipe (1), and an engine (17) is supported on the support plate (3). The rear wheels can be collected and laid down according to requirements, the collection and laying down operation is simple and quick, and the working efficiency of a mini tiller can be improved. The engine and the screw transmission box are installed horizontally, the mini tiller size can be further reduced, the installation is firm, and the stability is good.

Description

technical field [0001] The invention belongs to the technical field of tillage machines, and in particular relates to the arrangement structure of the rear wheel assembly, the engine and the screw transmission box on the 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 arr...

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

[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 screw transmission box is relatively complicated and the reliability is poor; the screw transmission box takes up a lot of space on the frame, and it will also increase the volume of the whole tiller
