Portable mini tiller engine screw transmission box and frame assembly

Abstract

The invention discloses a portable mini tiller engine screw transmission box and frame assembly. A beam (2) is arranged on the front portion between two horizontal sections of a main pipe (1), the beam (2) and the upper end of a front support (13) are fixed, the left end and the right end of the bottom of the front support (13) are connected with the top of the front end of a screw transmission box (12) through bolts, a support plate (3) is arranged in the middle between the two horizontal sections of the main pipe (1), and an engine (14) is supported onto the support plate (3). Arrangement of the engine, the screw transmission box, rear wheels and the like is facilitated, and the mini tiller can be developed in the miniaturization trend favorably. The engine is a horizontal engine, a user has many choices, the mini tiller size can be further reduced, and the engine is firm and reliable in installation and good in stability. The screw transmission box is horizontally installed, the mini tiller size can be further reduced, and the screw transmission box is firm and reliable in installation and good in stability.

Description

technical field [0001] The invention belongs to the technical field of tillage machines, and in particular relates to an engine, a screw transmission box and a frame assembly 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, blade, handle and ot...

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 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

[0005] 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
